    Gåvan till liv: upplevelser av att donera en njure2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att ge bort en del av sig själv för att förbättra livet för en annan människa, är att ge gåvan till liv. Levande njurdonatorers upplevelser kommer ofta i skymundan eftersom studier ofta fokuserat på mottagarens upple-velse av njurtransplantationen. Donationen beskrivs med både positiva och negativa upplevelser. De negati-va upplevelserna förknippas med fysiska och psykiska komplikationer efter donationen. De positiva upplevel-serna beskrivs som ökad livskvalitet och glädje inför att hjälpa en människa till ett bättre liv. Syftet med denna litteraturstudie var att beskriva levande donatorers upp-levelser av att donera en njure från beslutsfattandet till tiden efter donationen. Studien genomfördes som en lit-teraturstudie, där 13 artiklar granskades och analysera-des. Resultatet visar att det finns flera faktorer, såsom oro inför mottagarens situation och oro inför sin egen framtid som påverkar donatorernas beslutsfattande. Det framkom även att både fysiska och psykiska upplevelser förekommer efter donationen. De fysiska upplevelserna var framförallt smärta, illamående samt ömhet och obe-hag runt operationssåret. Donatorns psykiska upplevel-ser efter donationen var vanligen oro inför mottagarens tillfrisknande, stress, depression samt nedstämdhet. Överlag upplevde donatorerna donationen positivt och var nöjda med sitt beslut. Mer forskning kring levande njurdonatorers upplevelser kan bidra till att sjuksköters-kor lättare kan stödja donatorer i donationsprocessen samt att blivande donatorer kan få en inblick i hur dona-tionen upplevs.

    Increased CD4(+) T cell lineage commitment determined by CpG methylation correlates with better prognosis in urinary bladder cancer patients2018In: Clinical Epigenetics, E-ISSN 1868-7083, Vol. 10, article id 102Article in journal (Refereed)
    Abstract [en]

    Background: Urinary bladder cancer is a common malignancy worldwide. Environmental factors and chronic inflammation are correlated with the disease risk. Diagnosis is performed by transurethral resection of the bladder, and patients with muscle invasive disease preferably proceed to radical cystectomy, with or without neoadjuvant chemotherapy. The anti-tumour immune responses, known to be initiated in the tumour and draining lymph nodes, may play a major role in future treatment strategies. Thus, increasing the knowledge of tumour-associated immunological processes is important. Activated CD4(+) T cells differentiate into four main separate lineages: Th1, Th2, Th17 and Treg, and they are recognized by their effector molecules IFN-gamma, IL-13, IL-17A, and the transcription factor Foxp3, respectively. We have previously demonstrated signature CpG sites predictive for lineage commitment of these four major CD4(+ )T cell lineages. Here, we investigate the lineage commitment specifically in tumour, lymph nodes and blood and relate them to the disease stage and response to neoadjuvant chemotherapy.

    Results: Blood, tumour and regional lymph nodes were obtained from patients at time of transurethral resection of the bladder and at radical cystectomy. Tumour-infiltrating CD4(+ )lymphocytes were significantly hypomethylated in all four investigated lineage loci compared to CD4(+) lymphocytes in lymph nodes and blood (lymph nodes vs rumour-infiltrating lymphocytes: IFNG -4229 bp p < 0.0001, IL13 -11 bp p < 0.05, IL17A -122 bp p < 0.01 and FOXP3 -77 bp p> 0.05). Examination of individual lymph nodes displayed different methylation signatures, suggesting possible correlation with future survival. More advanced post-cystectomy tumour stages correlated significantly with increased methylation at the IFNG -4229 bp locus. Patients with complete response to neoadjuvant chemotherapy displayed significant hypomethylation in CD4(+ )T cells for all four investigated loci, most prominently in IFNG p < 0.0001. Neoadjuvant chemotherapy seemed to result in a relocation of Th1-committed CD4(+) T cells from blood, presumably to the tumour, indicated by shifts in the methylation patterns, whereas no such shifts were seen for lineages corresponding to IL13, IL17A and FOXP3.

    Conclusion: Increased lineage commitment in CD4(+) T cells, as determined by demethylation in predictive CpG sites, is associated with lower post-cystectomy tumour stage, complete response to neoadjuvant chemotherapy and overall better outcome, suggesting epigenetic profiling of CD4(+) T cell lineages as a useful readout for clinical staging.

    Large-scale fine mapping of the HNF1B locus and prostate cancer risk2011In: Human Molecular Genetics, ISSN 0964-6906, E-ISSN 1460-2083, Vol. 20, no 16, p. 3322-3329Article in journal (Refereed)
    Abstract [en]

    Previous genome-wide association studies have identified two independent variants in HNF1B as susceptibility loci for prostate cancer risk. To fine-map common genetic variation in this region, we genotyped 79 single nucleotide polymorphisms (SNPs) in the 17q12 region harboring HNF1B in 10 272 prostate cancer cases and 9123 controls of European ancestry from 10 case-control studies as part of the Cancer Genetic Markers of Susceptibility (CGEMS) initiative. Ten SNPs were significantly related to prostate cancer risk at a genome-wide significance level of P < 5 × 10(-8) with the most significant association with rs4430796 (P = 1.62 × 10(-24)). However, risk within this first locus was not entirely explained by rs4430796. Although modestly correlated (r(2)= 0.64), rs7405696 was also associated with risk (P = 9.35 × 10(-23)) even after adjustment for rs4430769 (P = 0.007). As expected, rs11649743 was related to prostate cancer risk (P = 3.54 × 10(-8)); however, the association within this second locus was stronger for rs4794758 (P = 4.95 × 10(-10)), which explained all of the risk observed with rs11649743 when both SNPs were included in the same model (P = 0.32 for rs11649743; P = 0.002 for rs4794758). Sequential conditional analyses indicated that five SNPs (rs4430796, rs7405696, rs4794758, rs1016990 and rs3094509) together comprise the best model for risk in this region. This study demonstrates a complex relationship between variants in the HNF1B region and prostate cancer risk. Further studies are needed to investigate the biological basis of the association of variants in 17q12 with prostate cancer.

    FGFR3, TERT and OTX1 as a Urinary Biomarker Combination for Surveillance of Patients with Bladder Cancer in a Large Prospective Multicenter Study2017In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 197, no 6, p. 1410-1418Article in journal (Refereed)
    Abstract [en]

    Purpose: Patients with nonmuscle invasive bladder cancer are followed with frequent cystoscopies. In this study FGFR3, TERT and OTX1 were investigated as a diagnostic urinary marker combination during followup of patients with primary nonmuscle invasive bladder cancer.

    Materials and Methods: In this international, multicenter, prospective study 977 patients with nonmuscle invasive bladder cancer were included. A total of 2,496 urine samples were collected prior to cystoscopy during regular visits. Sensitivity was estimated to detect concomitant recurrences. Kaplan-Meier curves were used to estimate the development of future recurrences after urinalysis and a negative cystoscopy.

    Results: Sensitivity of the assay combination for recurrence detection was 57% in patients with primary low grade, nonmuscle invasive bladder cancer. However, sensitivity was 83% for recurrences that were pT1 or muscle invasive bladder cancer. Of the cases 2% progressed to muscle invasive bladder cancer. Sensitivity for recurrence detection in patients with primary high grade disease was 72% and 7% of them had progression to muscle invasive bladder cancer. When no concomitant tumor was found by cystoscopy, positive urine samples were more frequently followed by a recurrence over time compared to a negative urine sample (58% vs 36%, p < 0.001). High stage recurrences were identified within 1 year after a positive urine test and a negative cystoscopy.

    Conclusions: Recurrences in patients with primary nonmuscle invasive bladder cancer can be detected by a combination of urine assays. This study supports the value of urinalysis as an alternative diagnostic tool in patients presenting with low grade tumors and as a means to identify high stage tumors earlier.

    Updated European Association of Urology Guidelines for Cytoreductive Nephrectomy in Patients with Synchronous Metastatic Clear-cell Renal Cell Carcinoma2018In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 74, no 6, p. 805-809Article in journal (Refereed)
    Abstract [en]

    Cytoreductive nephrectomy (CN) has been the standard of care in patients with metastatic clear-cell renal cancer who present with the tumour in place. The CARMENA trial compared systemic therapy alone with CN followed by systemic therapy. This article outlines the new guidelines based on these data.

    Patient summary: The CARMENA trial demonstrates that immediate cytoreductive nephrectomy should no longer be considered the standard of care in patients diagnosed with intermediate and poor risk metastatic renal cell carcinoma when medical treatment is required. However, the psychological burden poor risk patients experience hearing that removal of their primary tumour will not be beneficial, should be carefully considered.

    The multifaceted role of complement in kidney transplantation2018In: Nature Reviews Nephrology, ISSN 1759-5061, E-ISSN 1759-507X, Vol. 14, no 12, p. 767-781Article, review/survey (Refereed)
    Abstract [en]

    Increasing evidence indicates an integral role for the complement system in the deleterious inflammatory reactions that occur during critical phases of the transplantation process, such as brain or cardiac death of the donor, surgical trauma, organ preservation and ischaemia-reperfusion injury, as well as in humoral and cellular immune responses to the allograft. Ischaemia is the most common cause of complement activation in kidney transplantation and in combination with reperfusion is a major cause of inflammation and graft damage. Complement also has a prominent role in antibody-mediated rejection (ABMR) owing to ABO and HL A incompatibility, which leads to devastating damage to the transplanted kidney. Emerging drugs and treatment modalities that inhibit complement activation at various stages in the complement cascade are being developed to ameliorate the damage caused by complement activation in transplantation. These promising new therapies have various potential applications at different stages in the process of transplantation, including inhibiting the destructive effects of ischaemia and/or reperfusion injury, treating ABMR, inducing accommodation and modulating the adaptive immune response.

    Radical Prostatectomy or Watchful Waiting in Early Prostate Cancer2014In: New England Journal of Medicine, ISSN 0028-4793, E-ISSN 1533-4406, Vol. 370, no 10, p. 932-942Article in journal (Refereed)

    BackgroundRadical prostatectomy reduces mortality among men with localized prostate cancer; however, important questions regarding long-term benefit remain. MethodsBetween 1989 and 1999, we randomly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy and followed them through the end of 2012. The primary end points in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) were death from any cause, death from prostate cancer, and the risk of metastases. Secondary end points included the initiation of androgen-deprivation therapy. ResultsDuring 23.2 years of follow-up, 200 of 347 men in the surgery group and 247 of the 348 men in the watchful-waiting group died. Of the deaths, 63 in the surgery group and 99 in the watchful-waiting group were due to prostate cancer; the relative risk was 0.56 (95% confidence interval [CI], 0.41 to 0.77; P=0.001), and the absolute difference was 11.0 percentage points (95% CI, 4.5 to 17.5). The number needed to treat to prevent one death was 8. One man died after surgery in the radical-prostatectomy group. Androgen-deprivation therapy was used in fewer patients who underwent prostatectomy (a difference of 25.0 percentage points; 95% CI, 17.7 to 32.3). The benefit of surgery with respect to death from prostate cancer was largest in men younger than 65 years of age (relative risk, 0.45) and in those with intermediate-risk prostate cancer (relative risk, 0.38). However, radical prostatectomy was associated with a reduced risk of metastases among older men (relative risk, 0.68; P=0.04). ConclusionsExtended follow-up confirmed a substantial reduction in mortality after radical prostatectomy; the number needed to treat to prevent one death continued to decrease when the treatment was modified according to age at diagnosis and tumor risk. A large proportion of long-term survivors in the watchful-waiting group have not required any palliative treatment. (Funded by the Swedish Cancer Society and others.) The randomized Swedish trial of prostatectomy versus watchful waiting in disease detected mainly clinically (not by PSA screening) continues to show a benefit for early prostatectomy. The number of men younger than 65 needed to treat to prevent one death is now four. The Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4), a randomized trial of radical prostatectomy versus watchful waiting in men with localized prostate cancer diagnosed before the era of prostate-specific antigen (PSA) testing, showed a survival benefit of radical prostatectomy as compared with observation at 15 years of follow-up.(1) By contrast, the Prostate Cancer Intervention versus Observation Trial (PIVOT), initiated in the early era of PSA testing, showed that radical prostatectomy did not significantly reduce prostate cancer-specific or overall mortality after 12 years.(2) PSA screening profoundly changes the clinical domain of study. Among other considerations, the substantial additional lead time ...

    Radical Prostatectomy or Watchful Waiting in Prostate Cancer: 29-Year Follow-up2018In: New England Journal of Medicine, ISSN 0028-4793, E-ISSN 1533-4406, Vol. 379, no 24, p. 2319-2329Article in journal (Refereed)
    Abstract [en]

    BACKGROUND Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term followup is sparse.

    METHODS We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated. We evaluated the prognostic value of histopathological measures with a Cox proportional-hazards model.

    RESULTS By December 31, 2017, a total of 261 of the 347 men in the radical-prostatectomy group and 292 of the 348 men in the watchful-waiting group had died; 71 deaths in the radical-prostatectomy group and 110 in the watchful-waiting group were due to prostate cancer (relative risk, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001; absolute difference in risk, 11.7 percentage points; 95% CI, 5.2 to 18.2). The number needed to treat to avert one death from any cause was 8.4. At 23 years, a mean of 2.9 extra years of life were gained with radical prostatectomy. Among the men who underwent radical prostatectomy, extracapsular extension was associated with a risk of death from prostate cancer that was 5 times as high as that among men without extracapsular extension, and a Gleason score higher than 7 was associated with a risk that was 10 times as high as that with a score of 6 or lower (scores range from 2 to 10, with higher scores indicating more aggressive cancer).

    CONCLUSIONS Men with clinically detected, localized prostate cancer and a long life expectancy benefited from radical prostatectomy, with a mean of 2.9 years of life gained. A high Gleason score and the presence of extracapsular extension in the radical prostatectomy specimens were highly predictive of death from prostate cancer.

    Prediction of clinical progression after radical prostatectomy in a nationwide population-based cohort2016In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 50, no 4, p. 255-259Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to create a model for predicting progression-free survival after radical prostatectomy for localized prostate cancer. Material and methods: The risk of biochemical recurrence (BCR) was modelled in a cohort of 3452 men aged 70 years or younger who were primarily treated with radical prostatectomy after being diagnosed between 2003 and 2006 with localized prostate cancer [clinical stage T1c-T2, Gleason score 5-10, N0/NX, M0/MX, prostate-specific antigen (PSA)<20 ng/ml]. The cohort was split into two: one cohort for model development (n = 3452) and one for validation (n = 1762). BCR was defined as two increasing PSA values of at least 0.2 ng/ml, initiation of secondary therapy, distant metastases or death from prostate cancer. Multivariable Cox proportional hazard regression was applied, predictive performance was assessed using the bootstrap resampling technique to calculate the c index, and calibration of the model was evaluated by comparing predicted and observed Kaplan-Meier 1 year BCR. Results: The overall 5 year progression-free survival was 83% after a median follow-up time of 6.8 years in the development cohort and 7.3 years in the validation cohort. The final model included T stage, PSA level, primary and secondary Gleason grade, and number of positive and negative biopsies. The c index for discrimination between high and low risk of recurrence was 0.68. The probability of progression-free survival ranged from 22% to 97% over the range of risk scores in the study population. Conclusions: This model is based on nationwide population-based data and can be used with a fair predictive accuracy to guide decisions on clinical follow-up after prostatectomy. An online calculator for convenient clinical use of the model is available at www.npcr.se/nomogram

    Accuracy of GFR estimating equations combining standardized cystatin C and creatinine assays: a cross-sectional study in Sweden2015In: Clinical Chemistry and Laboratory Medicine, ISSN 1434-6621, E-ISSN 1437-4331, Vol. 53, no 3, p. 403-414Article in journal (Refereed)
    Abstract [en]

     Background: The recently established international cystatin C calibrator makes it possible to develop non-laboratory specific glomerular filtration rate (GFR) estimating (eGFR) equations. This study compares the performance of the arithmetic mean of the revised Lund-Malmö creatinine and CAPA cystatin C equations (MEANLM-REV+CAPA), the arithmetic mean of the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI) creatinine and cystatin C equations (MEANCKD-EPI), and the composite CKD-EPI equation (CKD-EPICREA+CYSC) with the corresponding single marker equations using internationally standardized calibrators for both cystatin C and creatinine.

    Methods: The study included 1200 examinations in 1112 adult Swedish patients referred for measurement of GFR (mGFR) 2008-2010 by plasma clearance of iohexol (median 51 mL/min/1.73 m2). Bias, precision (interquartile range, IQR) and accuracy (percentage of estimates ±30% of mGFR; P30) were compared.

    Results: Combined marker equations were unbiased and had higher precision and accuracy than single marker equations. Overall results of MEANLM-REV+CAPA/MEANCKD-EPI/CKD-EPICREA+CYSC were: median bias -2.2%/-0.5%/-1.6%, IQR 9.2/9.2/8.8 mL/min/1.73 m2, and P30 91.3%/91.0%/91.1%. The P30 figures were about 7-14 percentage points higher than the single marker equations. The combined equations also had a more stable performance across mGFR, age and BMI intervals, generally with P30 ≥90% and never <80%. Combined equations reached P30 of 95% when the difference between eGFRCREA and eGFRCYSC was <10% but decreased to 82% at a difference of ≥40%.

    Conclusions: Combining cystatin C and creatinine assays improves GFR estimations with P30 ≥90% in adults. Reporting estimates of both single and combined marker equations in clinical settings makes it possible to assess the validity of the combined equation based on the agreement between the single marker equations.

    Postoperative mortality 90 days after robot-assisted laparoscopic prostatectomy and retropubic radical prostatectomy: a nationwide population-based study2016In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 118, no 2, p. 302-306Article in journal (Refereed)
    Abstract [en]

    Objective To assess 90-day postoperative mortality after robot-assisted laparoscopic radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP) using nationwide population-based registry data. Patients and Methods We conducted a cohort study using the National Prostate Cancer Register of Sweden, including 22 344 men with localized prostate cancer of clinical stage T1-T3, whose prostate-specific antigen levels were <50 mu g/mL and who had undergone primary radical prostatectomy in the period 1998-2012. Vital status was ascertained through the Total Population Register. The rates for 90-day postoperative mortality were analysed using logistic regression analysis, and comparisons of 90-day mortality with the background population were made using standardized mortality ratios (SMRs). Results Of the 14 820 men who underwent RRP, 29 (0.20%) died, and of the 7 524 men who underwent RARP, 10 (0.13%) died. Mortality in the cohort during the 90-day postoperative period was lower than in an age-matched background population: SMR 0.57 (95% confidence interval [CI] 0.39-0.75). There was no statistically significant difference in 90-day mortality according to surgical method: RARP vs RRP odds ratio (OR) 1.14; 95% CI 0.46-2.81. Postoperative 90-day mortality decreased over time: 2008-2012 vs 1998-2007 OR 0.44; 95% CI 0.21-0.95, mainly because of lower mortality after RARP. Conclusion The 90-day postoperative mortality rates were low after RARP and RRP and there was no statistically significant difference between the methods. Given the long life expectancy among men with low-and intermediate-risk prostate cancer, very low postoperative mortality is a prerequisite for RP, which was fulfilled by both RRP and RARP. The selection of healthy men for RP is highlighted by the lower 90-day mortality after RP compared with the background population.

    ABCB1 Variation Affects Myelosuppression, Progression-free Survival and Overall Survival in Paclitaxel/Carboplatin-treated Ovarian Cancer Patients2018In: Basic & Clinical Pharmacology & Toxicology, ISSN 1742-7835, E-ISSN 1742-7843, Vol. 123, no 3, p. 277-287Article in journal (Refereed)
    Abstract [en]

    The standard chemotherapy for ovarian cancer is paclitaxel/carboplatin. Patients often exhibit myelosuppressive toxicity, and the treatment response varies considerably. In this study, we investigated the previously reported SNPs 1199Gamp;gt;A (rs2229109), 1236Camp;gt;T (rs1128503), 2677Gamp;gt;T/A (rs2032582), 3435Camp;gt;T (rs1045642) in ABCB1, and 1196Aamp;gt;G (rs10509681) in CYP2C8 and their association with treatment-induced myelosuppression, progression-free survival (PFS) and overall survival (OS). From the phase III study, OAS-07OVA, 525 patients (All) treated with carboplatin and paclitaxel administered as Paclical (Arm A, n=260) or Taxol((R)) (Arm B, n=265) were included and genotyped using pyrosequencing. Genotype associations with myelosuppression, PFS and OS were investigated using anova, Kaplan-Meier analysis and Cox proportional hazard models. The most prominent finding was for the ABCB1 variant 3435TT, which was significantly associated with increased PFS in All (hazard ratio (HR) = 0.623), in Arm A (HR=0.590) and in Arm B (HR=0.627), as well as increased OS in All (HR=0.443) and in Arm A (HR=0.372) compared to the wild-type, 3435CC. For toxicity, the most interesting finding concerned the haplotype, including 1236TT, 2677TT and 3435TT, which was associated with higher neutrophil values in Arm B (p=0.039) and less neutrophil decrease in All (p=0.048) and in Arm B (p=0.021). It is noteworthy that the results varied depending on the treatment arm which indicates that the effects of ABCB1 variants vary with the treatment regimen. Our results reflect the contradictory results of previous studies, confirming that small variations in the composition of treatment regimens and patient populations may influence the interpretation of SNPs effects on treatment outcome.

    Prostate Cancer Radiation Therapy and Risk of Thromboembolic Events2017In: International Journal of Radiation Oncology, Biology, Physics, ISSN 0360-3016, E-ISSN 1879-355X, Vol. 97, no 5, p. 1026-1031Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate the risk of thromboembolic disease (TED) after radiation therapy (RT) with curative intent for prostate cancer (PCa). Patients and Methods: We identified all men who received RT as curative treatment (n=9410) and grouped according to external beam RT (EBRT) or brachytherapy (BT). By comparing with an age-and county-matched comparison cohort of PCa-free men (n = 46,826), we investigated risk of TED after RT using Cox proportional hazard regression models. The model was adjusted for tumor characteristics, demographics, comorbidities, PCa treatments, and known risk factors of TED, such as recent surgery and disease progression. Results: Between 2006 and 2013, 6232 men with PCa received EBRT, and 3178 underwent BT. A statistically significant association was found between EBRT and BT and risk of pulmonary embolism in the crude analysis. However, upon adjusting for known TED risk factors these associations disappeared. No significant associations were found between BT or EBRT and deep venous thrombosis. Conclusion: Curative RT for prostate cancer using contemporary methodologies was not associated with an increased risk of TED.

    Subgroups of castration-resistant prostate cancer bone metastases defined through an inverse relationship between androgen receptor activity and immune response2017In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 71, no 5, p. 776-787Article in journal (Refereed)
    Abstract [en]

    Background: Novel therapies for men with castration-resistant prostate cancer (CRPC) are needed, particularly for cancers not driven by androgen receptor (AR) activation. Objectives: To identify molecular subgroups of PC bone metastases of relevance for therapy.

    Design, setting, and participants: Fresh-frozen bone metastasis samples from men with CRPC (n = 40), treatment-naïve PC (n = 8), or other malignancies (n = 12) were characterized using whole-genome expression profiling, multivariate principal component analysis (PCA), and functional enrichment analysis. Expression profiles were verified by reverse transcription–polymerase chain reaction (RT-PCR) in an extended set of bone metastases (n = 77) and compared to levels in malignant and adjacent benign prostate tissue from patients with localized disease (n = 12). Selected proteins were evaluated using immunohistochemistry. A cohort of PC patients (n = 284) diagnosed at transurethral resection with long follow-up was used for prognostic evaluation.

    Results and limitations: The majority of CRPC bone metastases (80%) was defined as AR-driven based on PCA analysis and high expression of the AR, AR co-regulators (FOXA1, HOXB13), and AR-regulated genes (KLK2, KLK3, NKX3.1, STEAP2, TMPRSS2); 20% were non–AR-driven. Functional enrichment analysis indicated high metabolic activity and low immune responses in AR-driven metastases. Accordingly, infiltration of CD3+ and CD68+ cells was lower in AR-driven than in non–AR-driven metastases, and tumor cell HLA class I ABC immunoreactivity was inversely correlated with nuclear AR immunoreactivity. RT-PCR analysis showed low MHC class I expression (HLA-A, TAP1, and PSMB9 mRNA) in PC bone metastases compared to benign and malignant prostate tissue and bone metastases of other origins. In primary PC, low HLA class I ABC immunoreactivity was associated with high Gleason score, bone metastasis, and short cancer-specific survival. Limitations include the limited number of patients studied and the single metastasis sample studied per patient.

    Conclusions: Most CRPC bone metastases show high AR and metabolic activities and low immune responses. A subgroup instead shows low AR and metabolic activities, but high immune responses. Targeted therapy for these groups should be explored. Patient summary: We studied heterogeneities at a molecular level in bone metastasis samples obtained from men with castration-resistant prostate cancer. We found differences of possible importance for therapy selection in individual patients.

    Erythrocytes as volume markers in experimental pd show that albumin transport in the extracellular space depends on pd fluid osmolarity2016In: Peritoneal Dialysis International, ISSN 0896-8608, E-ISSN 1718-4304, Vol. 36, no 3, p. 247-256Article in journal (Refereed)
    Abstract [en]

    Background: Macromolecules, when used as intraperitoneal volume markers, have the disadvantage of leaking into the surrounding tissue. Therefore, Cr-51-labeled erythrocytes were evaluated as markers of intraperitoneal volume and used in combination with I-125-labeled bovine serum albumin to study albumin transport into peritoneal tissues in a rat model of peritoneal dialysis (PD).

    Methods: Single dwells of 20 mL of lactate-buffered filter-sterilized PD fluid at glucose concentrations of 0.5%, 2.5%, and 3.9% were performed for 1 or 4 hours. Tissue biopsies from abdominal muscle, diaphragm, liver, and intestine, and blood and dialysate samples, were analyzed for radioactivity.

    Results: The dialysate distribution volume of labeled erythrocytes, measured after correction for lymphatic clearance to blood, was strongly correlated with, but constantly 3.3 mL larger than, drained volumes. Erythrocyte activity of rinsed peritoneal tissue biopsies corresponded to only 1 mL of dialysate, supporting our utilization of erythrocytes as markers of intraperitoneal volume. The difference between the distribution volumes of albumin and erythrocytes was analyzed to represent the albumin loss into the peritoneal tissues, which increased rapidly during the first few minutes of the dwell and then leveled out at 2.5 mL. It resumed when osmotic ultrafiltration turned into reabsorption and, at the end of the dwell, it was significantly lower for the highest osmolarity PD fluid (3.9% glucose). Biopsy data showed the lowest albumin accumulation and edema formation in abdominal muscle for the 3.9% fluid.

    Conclusion: Labeled erythrocytes are acceptable markers of intraperitoneal volume and, combined with labeled albumin, provided novel kinetic data on albumin transport in peritoneal tissues.

    Open-label, clinical phase I studies of tasquinimod in patients with castration-resistant prostate cancer2009In: British Journal of Cancer, ISSN 0007-0920, E-ISSN 1532-1827, Vol. 101, no 8, p. 1233-40Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Tasquinimod is a quinoline-3-carboxamide derivative with anti-angiogenic activity. Two open-label phase I clinical trials in patients were conducted to evaluate the safety and tolerability of tasquinimod, with additional pharmacokinetic and efficacy assessments. METHODS: Patients with castration-resistant prostate cancer with no previous chemotherapy were enrolled in this study. The patients received tasquinimod up to 1 year either at fixed doses of 0.5 or 1.0 mg per day or at an initial dose of 0.25 mg per day that escalated to 1.0 mg per day. RESULTS: A total of 32 patients were enrolled; 21 patients were maintained for >or=4 months. The maximum tolerated dose was determined to be 0.5 mg per day; but when using stepwise intra-patient dose escalation, a dose of 1.0 mg per day was well tolerated. The dose-limiting toxicity was sinus tachycardia and asymptomatic elevation in amylase. Common treatment-emergent adverse events included transient laboratory abnormalities, anaemia, nausea, fatigue, myalgia and pain. A serum prostate-specific antigen (PSA) decline of >or=50% was noted in two patients. The median time to PSA progression (>25%) was 19 weeks. Only 3 out of 15 patients (median time on study: 34 weeks) developed new bone lesions. CONCLUSION: Long-term continuous oral administration of tasquinimod seems to be safe, and the overall efficacy results indicate that tasquinimod might delay disease progression.

    The Study of Active Monitoring in Sweden (SAMS): A randomized study comparing two different follow-up schedules for active surveillance of low-risk prostate cancer2013In: Scandinavian Journal of Urology, ISSN 2168-1805, Vol. 47, no 5, p. 347-355Article, review/survey (Refereed)
    Abstract [en]

    Objective. Only a minority of patients with low-risk prostate cancer needs treatment, but the methods for optimal selection of patients for treatment are not established. This article describes the Study of Active Monitoring in Sweden (SAMS), which aims to improve those methods. Material and methods. SAMS is a prospective, multicentre study of active surveillance for low-risk prostate cancer. It consists of a randomized part comparing standard rebiopsy and follow-up with an extensive initial rebiopsy coupled with less intensive follow-up and no further scheduled biopsies (SAMS-FU), as well as an observational part (SAMS-ObsQoL). Quality of life is assessed with questionnaires and compared with patients receiving primary curative treatment. SAMS-FU is planned to randomize 500 patients and SAMS-ObsQoL to include at least 500 patients during 5 years. The primary endpoint is conversion to active treatment. The secondary endpoints include symptoms, distant metastases and mortality. All patients will be followed for 10-15 years. Results. Inclusion started in October 2011. In March 2013, 148 patients were included at 13 Swedish urological centres. Conclusions. It is hoped that the results of SAMS will contribute to fewer patients with indolent, low-risk prostate cancer receiving unnecessary treatment and more patients on active surveillance who need treatment receiving it when the disease is still curable. The less intensive investigational follow-up in the SAMS-FU trial would reduce the healthcare resources allocated to this large group of patients if it replaced the present standard schedule.

    Family History and Probability of Prostate Cancer, Differentiated by Risk Category: A Nationwide Population-Based Study2016In: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 108, no 10, article id djw110Article in journal (Refereed)
    Abstract [en]

    Background: Familial prostate cancer risk estimates are inflated by clinically insignificant low-risk cancer, diagnosed after prostate-specific antigen testing. We provide age-specific probabilities of non-low-and high-risk prostate cancer. Methods: Fifty-one thousand, eight hundred ninety-seven brothers of 32 807 men with prostate cancer were identified in Prostate Cancer data Base Sweden (PCBaSe). Nelson-Aalen estimates with 95% confidence intervals (CIs) were calculated for cumulative, family history-stratified probabilities of any, non-low-(any of Gleason score >= 7, prostate-specific antigen [PSA] >= 10 ng/mL, T3-4, N1, and/or M1) and high-risk prostate cancer (Gleason score >= 8 and/or T3-4 and/or PSA >= 20 ng/mL and/or N1 and/or M1). Results: The population probability of any prostate cancer was 4.8% (95% CI = 4.8% to 4.9%) at age 65 years and 12.9% (95% CI = 12.8% to 12.9%) at age 75 years, of non-low-risk prostate cancer 2.8% (95% CI = 2.7% to 2.8%) at age 65 years and 8.9% (95% CI = 8.8% to 8.9%) at age 75 years, and of high-risk prostate cancer 1.4% (95% CI = 1.3% to 1.4%) at age 65 years and 5.2% (95% CI = 5.1% to 5.2%) at age 75 years. For men with one affected brother, probabilities of any prostate cancer were 14.9% (95% CI = 14.1% to 15.8%) at age 65 years and 30.3% (95% CI = 29.3% to 31.3%) at age 75 years, of non-low-risk prostate cancer 7.3% (95% CI = 6.7% to 7.9%) at age 65 years and 18.8% (95% CI = 17.9% to 19.6%) at age 75 years, and of high-risk prostate cancer 3.0% (95% CI = 2.6% to 3.4%) at age 65 years and 8.9% (95% CI = 8.2% to 9.5%) at age 75 years. Probabilities were higher for men with a stronger family history. For example, men with two affected brothers had a 13.6% (95% CI = 9.9% to 17.6 %) probability of high-risk cancer at age 75 years. Conclusions: The age-specific probabilities of non-low-and high-risk cancer presented here are more informative than relative risks of any prostate cancer and more suitable to use for counseling men with a family history of prostate cancer.

    Undertreatment of Men in Their Seventies with High-risk Nonmetastatic Prostate Cancer2015In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 68, no 1, p. 53-58Article in journal (Refereed)
    Abstract [en]

    Background: Many elderly men with high-risk nonmetastatic prostate cancer (HRnMPCa) do not receive radical treatment, despite the high mortality associated with conservative management. Objective: To investigate how age and comorbidity affect treatment of men with HRnMPCa. Design, setting, and participants: This was an observational nationwide register study during 2001-2012. We identified 19 190 men of <80 yr of age diagnosed with HRnMPCa in the National Prostate Cancer Register of Sweden and 95 948 age-matched men without prostate cancer in the register of the total population. Outcome measurements and statistical analysis: The outcome was the proportion of men with HRnMPCa receiving radical treatment (radical prostatectomy or radiotherapy). Vital status and the Charlson comorbidity index (CCI) were obtained from nationwide registers. The 10-yr survival of men without prostate cancer, stratified by age and CCI, was used as a measure of the life expectancy of the men with prostate cancer. Results and limitations: The proportions receiving radical treatment varied with life expectancy among men younger than 70 yr, whereas use of these treatments did not match the long life expectancy of men in their seventies with CCI 0-1. Only 10% of men aged 75-80 yr with CCI 0 received radical treatment despite 52% probability of 10-yr life expectancy, compared with approximately half of the men younger than 70 yr with a similar life expectancy. The use of radical treatment for HRnMPCa increased with time in all Swedish counties, but a threefold difference between counties remained in 2009-2012 for patients aged 70-80 yr with CCI 0-1. Uncertain external validity is a study limitation, and the impact of physician versus patient preferences on treatment selection could not be assessed. Conclusions: Otherwise healthy men in their seventies with HRnMPCa were less likely to receive radical treatment than younger men with a similar life expectancy, although increasing use of radical treatment was observed during the study period. Our findings highlight the need for improved methods for clinical decision-making, including improved assessment of life expectancy. Patient summary: We performed a nationwide register study that showed that many healthy men in their seventies live for at least another 10 yr. Despite this long life expectancy, men in their seventies with high-risk nonmetastatic prostate cancer were often not treated with radical prostatectomy or radiotherapy, possibly because their life expectancy was underestimated. Our study highlights the need for improved clinical decision-making, which should incorporate an assessment of the patient's life expectancy.

    The Value of an Extensive Transrectal Repeat Biopsy with Anterior Sampling in Men on Active Surveillance for Low-risk Prostate Cancer: A Comparison from the Randomised Study of Active Monitoring in Sweden (SAMS)2019In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 76, no 4, p. 461-466Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: A systematic repeat biopsy is recommended for men starting on active surveillance for prostate cancer, but the optimal number and distribution of cores are unknown.

    OBJECTIVE: To evaluate an extensive repeat transrectal biopsy with anterior sampling in men starting on active surveillance.

    DESIGN, SETTING, AND PARTICIPANTS: Randomised multicentre trial. From 2012 to 2016, 340 Swedish men, aged 40-75yr, with recently diagnosed low-volume Gleason grade group 1 prostate cancer were included.

    INTERVENTION: Either an extensive transrectal biopsy with anterior sampling (median 19 cores) or a standard transrectal biopsy (median 12 cores).

    OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome measure: Gleason grade group ≥2 cancer.

    SECONDARY OUTCOMES: Cancer in anteriorly directed biopsy cores and postbiopsy infection. Nonparametric statistical tests were applied.

    RESULTS AND LIMITATIONS: Gleason grade group ≥2 cancer was detected in 16% of 156 men who had an extensive biopsy and in 10% of 164 men who had a standard biopsy, a 5.7% difference (95% confidence interval [CI]-0.2% to 13%, p=0.09). There was a strong linear association between prostate-specific antigen (PSA) density and cancer in the anteriorly directed biopsy cores. The odds ratios for cancer in the anteriorly directed cores were for any cancer 2.2 (95% CI 1.3-3.9, p=0.004) and for Gleason grade group ≥2 cancer 2.3 (95% CI 1.2-4.4, p=0.015) per 0.1-ng/ml/cm3 increments. Postbiopsy infections were equally common in the two groups. A limitation is that magnetic resonance imaging was not used.

    CONCLUSIONS: The trial did not support general use of the extensive transrectal repeat biopsy template, but cancer in the anteriorly directed cores was common, particularly in men with high PSA density. The higher the PSA density, the stronger the reason to include anterior sampling at a systematic repeat biopsy.

    PATIENT SUMMARY: This trial compared two different templates for transrectal prostate biopsy in men starting on active surveillance for low-risk prostate cancer. Cancer was often found in the front part of the prostate, which is not sampled on a standard prostate biopsy.

    Methodology used in studies reporting chronic kidney disease prevalence: a systematic literature review2015In: Nephrology, Dialysis and Transplantation, ISSN 0931-0509, E-ISSN 1460-2385, Vol. 30, no S4, p. 6-16Article, review/survey (Refereed)
    Abstract [en]

    Background. Many publications report the prevalence of chronic kidney disease (CKD) in the general population. Comparisons across studies are hampered as CKD prevalence estimations are influenced by study population characteristics and laboratory methods. Methods. For this systematic review, two researchers independently searched PubMed, MEDLINE and EMBASE to identify all original research articles that were published between 1 January 2003 and 1 November 2014 reporting the prevalence of CKD in the European adult general population. Data on study methodology and reporting of CKD prevalence results were independently extracted by two researchers. Results. We identified 82 eligible publications and included 48 publications of individual studies for the data extraction. There was considerable variation in population sample selection. The majority of studies did not report the sampling frame used, and the response ranged from 10 to 87%. With regard to the assessment of kidney function, 67% used a Jaffe assay, whereas 13% used the enzymatic assay for creatinine determination. Isotope dilution mass spectrometry calibration was used in 29%. The CKD-EPI (52%) and MDRD (75%) equations were most often used to estimate glomerular filtration rate (GFR). CKD was defined as estimated GFR (eGFR) <60 mL/min/1.73 m(2) in 92% of studies. Urinary markers of CKD were assessed in 60% of the studies. CKD prevalence was reported by sex and age strata in 54 and 50% of the studies, respectively. In publications with a primary objective of reporting CKD prevalence, 39% reported a 95% confidence interval. Conclusions. The findings from this systematic review showed considerable variation in methods for sampling the general population and assessment of kidney function across studies reporting CKD prevalence. These results are utilized to provide recommendations to help optimize both the design and the reporting of future CKD prevalence studies, which will enhance comparability of study results.

    CKD Prevalence Varies across the European General Population2016In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 27, no 7, p. 2135-2147Article in journal (Refereed)
    Abstract [en]

    CKD prevalence estimation is central to CKD management and prevention planning at the population level. This study estimated CKD prevalence in the European adult general population and investigated international variation in CKD prevalence by age, sex, and presence of diabetes, hypertension, and obesity. We collected data from 19 general-population studies from 13 European countries. CKD stages 1-5 was defined as eGFR <60 ml/min per 1.73 m(2), as calculated by the CKD-Epidemiology Collaboration equation, or albuminuria >30 mg/g, and CKD stages 3-5 was defined as eGFR<60 ml/min per 1.73 m(2). CKD prevalence was age- and sex-standardized to the population of the 27 Member States of the European Union (EU27). We found considerable differences in both CKD stages 1-5 and CKD stages 3-5 prevalence across European study populations. The adjusted CKD stages 1-5 prevalence varied between 3.31% (95% confidence interval [95% CI], 3.30% to 3.33%) in Norway and 17.3% (95% Cl, 16.5% to 18.1%) in northeast Germany. The adjusted CKD stages 3-5 prevalence varied between 1.0% (95% CI, 0.7% to 1.3%) in central Italy and 5.9% (95% CI, 5.2% to 6.6%) in northeast Germany. The variation in CKD prevalence stratified by diabetes, hypertension, and obesity status followed the same pattern as the overall prevalence. In conclusion, this large-scale attempt to carefully characterize CKD prevalence in Europe identified substantial variation in CKD prevalence that appears to be due to factors other than the prevalence of diabetes, hypertension, and obesity.

    The impact of the extent of lymphadenectomy on oncologic outcomes in patients undergoing radical cystectomy for bladder cancer: a systematic review2014In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 66, no 6, p. 1065-1077Article in journal (Refereed)
    Abstract [en]

    CONTEXT: Controversy exists regarding the therapeutic value of lymphadenectomy (LND) in patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). OBJECTIVE: To systematically review the relevant literature assessing the impact of LND on oncologic and perioperative outcomes in patients undergoing RC for MIBC. EVIDENCE ACQUISITION: Medline, Medline In-Process, Embase, the Cochrane Central Register of Controlled Trials, and the Latin American and Caribbean Center on Health Sciences Information (LILACS) were searched up to December 2013. Comparative studies reporting on no LND, limited LND (L-LND), standard LND (S-LND), extended LND (E-LND), superextended LND (SE-LND), and oncologic and perioperative outcomes were included. Risk-of-bias and confounding assessments were performed. EVIDENCE SYNTHESIS: Twenty-three studies reporting on 19 793 patients were included. All but one study were retrospective. Planned meta-analyses were not possible because of study heterogeneity; therefore, data were synthesized narratively. There were high risks of bias and confounding across most studies as well as extreme heterogeneity in the definition of the anatomic boundaries of LND templates. All seven studies comparing LND with no LND favored LND in terms of better oncologic outcomes. Seven of 14 studies comparing (super)extended LND with L-LND or S-LND reported a beneficial outcome for (super)extended LND in at least a subset of patients. No difference in outcome was reported in two studies comparing E-LND and S-LND. The comparative harms of different extents of LND remain unclear. CONCLUSIONS: Although the quality of the data was poor, the available evidence indicates that any kind of LND is advantageous over no LND. Similarly, E-LND appears to be superior to lesser degrees of dissection, while SE-LND offered no additional benefits. It is hoped that data from ongoing randomized clinical trials will clarify remaining uncertainties. PATIENT SUMMARY: The current literature suggests that removal of lymph nodes in bladder cancer surgery is beneficial and might result in better outcomes in terms of prolonging survival; however, the quality of the available studies is poor, and high-quality studies are needed.

    Ouabain Protects against Shiga Toxin-Triggered Apoptosis by Reversing the Imbalance between Bax and Bcl-xL2013In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 24, no 9, p. 1413-1423Article in journal (Refereed)
    Abstract [en]

    Hemolytic uremic syndrome, a life-threatening disease often accompanied by acute renal failure, usually occurs after gastrointestinal infection with Shiga toxin 2 (Stx2)-producing Escherichia coli. Stx2 binds to the glycosphingolipid globotriaosylceramide receptor, expressed by renal epithelial cells, and triggers apoptosis by activating the apoptotic factor Bax. Signaling via the ouabain/Na,K-ATPase/IP3R/NF-B pathway increases expression of Bcl-xL, an inhibitor of Bax, suggesting that ouabain might protect renal cells from Stx2-triggered apoptosis. Here, exposing rat proximal tubular cells to Stx2 in vitro resulted in massive apoptosis, upregulation of the apoptotic factor Bax, increased cleaved caspase-3, and downregulation of the survival factor Bcl-xL; co-incubation with ouabain prevented all of these effects. Ouabain activated the NF-B antiapoptotic subunit p65, and the inhibition of p65 DNA binding abolished the antiapoptotic effect of ouabain in Stx2-exposed tubular cells. Furthermore, in vivo, administration of ouabain reversed the imbalance between Bax and Bcl-xL in Stx2-treated mice. Taken together, these results suggest that ouabain can protect the kidney from the apoptotic effects of Stx2.

    Prevention of apoptosis averts glomerular tubular disconnection and podocyte loss in proteinuric kidney disease2016In: Kidney International, ISSN 0085-2538, E-ISSN 1523-1755, Vol. 90, no 1, p. 135-148Article in journal (Refereed)
    Abstract [en]

    There is a great need for treatment that arrests progression of chronic kidney disease. Increased albumin in urine leads to apoptosis and fibrosis of podocytes and tubular cells and is a major cause of functional deterioration. There have been many attempts to target fibrosis, but because of the lack of appropriate agents, few have targeted apoptosis. Our group has described an ouabain-activated Na,K-ATPase/IP3R signalosome, which protects from apoptosis. Here we show that albumin uptake in primary rat renal epithelial cells is accompanied by a time-and dose-dependent mitochondrial accumulation of the apoptotic factor Bax, down-regulation of the antiapoptotic factor Bcl-xL and mitochondrial membrane depolarization. Ouabain opposes these effects and protects from apoptosis in albumin-exposed proximal tubule cells and podocytes. The efficacy of ouabain as an antiapoptotic and kidney-protective therapeutic tool was then tested in rats with passive Heymann nephritis, a model of proteinuric chronic kidney disease. Chronic ouabain treatment preserved renal function, protected from renal cortical apoptosis, up-regulated Bax, down-regulated Bcl-xL, and rescued from glomerular tubular disconnection and podocyte loss. Thus we have identified a novel clinically feasible therapeutic tool, which has the potential to protect from apoptosis and rescue from loss of functional tissue in chronic proteinuric kidney disease.

    Who should record surgical complications?: Results from a third-party assessment of complications after radical cystectomy2019In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813Article in journal (Refereed)
    Abstract [en]

    Objective: In Sweden complications after radical cystectomy have been reported to the nationwide population-based Swedish Cystectomy Registry since 2011. Here, validation of the reporting was assessed in two healthcare regions.

    Materials and methods: Complications were ascertained from patient records by a third party not involved in the care delivered to 429 randomly selected patients from 949 who had undergone radical cystectomy since 2011 in four hospitals. Without knowledge of the outcome in the primary registration, post-operative complications within 90 days post-operatively were assessed by an independent review of patient charts, and the results were compared with the primary reports in the Swedish Cystectomy Registry.

    Results: The third-party assessment identified post-operative complications in 310 patients (72%). Low-grade complications (Clavien-Dindo I-II) were noted in 110 (26%) of the patients in the primary registration, but increased to 182 (42%) in the validation (p < 0.00001). High-grade complications (Clavien-Dindo III-V) were reported in 113 (26%) patients in the primary registration, but in 128 (30%) of the patients in the validation (p = 0.02). According to the third-party assessment, 18 patients (4%) had Clavien-Dindo grade IV complications and 12 (3%) died within 90 days of surgery (Clavien-Dindo grade V); corresponding values in the primary registration were 15 (3%) and 9 (2%), respectively. The readmission rate within 90 days increased from 27 to 32% in the validation (p < 0.00001).

    Conclusions: Compared with registry data, third-party assessment revealed more complications and readmissions after radical cystectomy. Hence such evaluation may improve the validity of reported complication data.

    Variety in vegetable and fruit consumption and risk of bladder cancer in the European prospective investigation into cancer and nutrition2011In: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 128, no 12, p. 2971-2979Article in journal (Refereed)
    Abstract [en]

    Recent research does not show an association between fruit and vegetable consumption and bladder cancer risk. None of these studies investigated variety in fruit and vegetable consumption, which may capture different aspects of consumption. We investigated whether a varied consumption of vegetables and fruits is associated with bladder cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Detailed data on food consumption and complete follow-up for cancer incidence were available for 452,185 participants, who were recruited from ten European countries. After a mean follow-up of 8.7 years, 874 participants were diagnosed with bladder cancer. Diet diversity scores (DDSs) were used to quantify the variety in fruit and vegetable consumption. Multivariable Cox proportional hazard models were used to assess the effect of the DDSs on bladder cancer risk. There was no evidence of a statistically significant association between bladder cancer risk and any of the DDSs when these scores were considered as continuous covariates. However, the hazard ratio (HR) for the highest tertile of the DDS for combined fruit and vegetable consumption was marginally significant compared to the lowest (HR = 1.30, 95% confidence interval: 1.00-1.69, p-trend = 0.05). In EPIC, there is no clear association between a varied fruit and vegetable consumption and bladder cancer risk. This finding provides further evidence for the absence of any strong association between fruit and vegetable consumption as measured by a food frequency questionnaire and bladder cancer risk.

    Exome-Based Rare-Variant Analyses in CKD2019In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 30, no 6, p. 1109-1122Article in journal (Refereed)
    Abstract [en]

    Background Studies have identified many common genetic associations that influence renal function and all-cause CKD, but these explain only a small fraction of variance in these traits. The contribution of rare variants has not been systematically examined. Methods We performed exome sequencing of 3150 individuals, who collectively encompassed diverse CKD subtypes, and 9563 controls. To detect causal genes and evaluate the contribution of rare variants we used collapsing analysis, in which we compared the proportion of cases and controls carrying rare variants per gene. Results The analyses captured five established monogenic causes of CKD: variants in PKD1, PKD2, and COL4A5 achieved study-wide significance, and we observed suggestive case enrichment for COL4A4 and COL4A3. Beyond known disease-associated genes, collapsing analyses incorporating regional variant intolerance identified suggestive dominant signals in CPT2 and several other candidate genes. Biallelic mutations in CPT2 cause carnitine palmitoyltransferase II deficiency, sometimes associated with rhabdomyolysis and acute renal injury. Genetic modifier analysis among cases with APOL1 risk genotypes identified a suggestive signal in AHDC1, implicated in Xia-Gibbs syndrome, which involves intellectual disability and other features. On the basis of the observed distribution of rare variants, we estimate that a two-to three-fold larger cohort would provide 80% power to implicate new genes for all-cause CKD. Conclusions This study demonstrates that rare-variant collapsing analyses can validate known genes and identify candidate genes and modifiers for kidney disease. In so doing, these findings provide a motivation for larger-scale investigation of rare-variant risk contributions across major clinical CKD categories.

    Use of Proteomics To Investigate Kidney Function Decline over 5 Years2017In: American Society of Nephrology. Clinical Journal, ISSN 1555-9041, E-ISSN 1555-905X, Vol. 12, no 8, p. 1226-1235Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Using a discovery/replication approach, we investigated associations between a multiplex panel of 80 circulating proteins associated with cardiovascular pathology or inflammation, and eGFR decline per year and CKD incidence.

    DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used two cohorts, the Prospective Investigation of the Vasculature in Uppsala Seniors Study (PIVUS; n=687, mean age of 70 years, 51% women) and the Uppsala Longitudinal Study of Adult Men (ULSAM; n=360 men, mean age of 78 years), with 5-year follow-up data on eGFR. There were 231 and 206 incident cases of CKD during follow-up in the PIVUS and ULSAM studies, respectively. Proteomic profiling of 80 proteins was assessed by a multiplex assay (proximity extension assay). The assay uses two antibodies for each protein and a PCR step to achieve a high-specific binding and the possibility to measure multiple proteins in parallel, but gives no absolute concentrations.

    RESULTS: In the discovery cohort from the PIVUS Study, 28 plasma proteins were significantly associated with eGFR decline per year, taking into account the multiple testing. Twenty of these proteins were significantly associated with eGFR decline per year in the replication cohort from the ULSAM Study after adjustment for age, sex, cardiovascular risk factors, medications, and urinary albumin-to-creatinine ratio (in order of significance: TNF-related apoptosis-inducing ligand receptor 2*, CD40L receptor, TNF receptor 1*, placenta growth factor*, thrombomodulin*, urokinase plasminogen activator surface receptor*, growth/differentiation factor 15*, macrophage colony-stimulating factor 1, fatty acid-binding protein*, cathepsin D, resistin, kallikrein 11*, C-C motif chemokine 3, proteinase-activated receptor 1*, cathepsin L, chitinase 3-like protein 1, TNF receptor 2*, fibroblast growth factor 23*, monocyte chemotactic protein 1, and kallikrein 6). Moreover, 11 of the proteins predicted CKD incidence (marked with * above). No protein consistently predicted eGFR decline per year independently of baseline eGFR in both cohorts.

    CONCLUSIONS: Several circulating proteins involved in phosphate homeostasis, inflammation, apoptosis, extracellular matrix remodeling, angiogenesis, and endothelial dysfunction were associated with worsening kidney function. Multiplex proteomics appears to be a promising way of discovering novel aspects of kidney disease pathology.

    Urinary Kidney Injury Molecule-1 and the Risk of Cardiovascular Mortality in Elderly Men2014In: Clinical journal of the American Society of Nephrology : CJASN, ISSN 1555-905X, Vol. 9, no 8, p. 1393-1401Article in journal (Refereed)
    Abstract [en]

    Background and objectives

    Kidney injury molecule-1 (KIM-1) has been suggested as a clinically relevant highly specific biomarker of acute kidney tubular damage. However, community-based data on the association between urinary levels of KIM-1 and the risk for cardiovascular mortality are lacking. This study aimed to investigate the association between urinary KIM-1 and cardiovascular mortality.

    Design, setting, participants, & measurements

    This was a prospective study, using the community-based Uppsala Longitudinal Study of Adult Men (N=590; mean age 77 years; baseline period, 1997–2001; median follow-up 8.1 years; end of follow-up, 2008).

    Results

    During follow-up, 89 participants died of cardiovascular causes (incidence rate, 2.07 per 100 person-years at risk). Models were adjusted for cardiovascular risk factors (age, systolic BP, diabetes, smoking, body mass index, total cholesterol, HDL cholesterol, antihypertensive treatment, lipid-lowering treatment, aspirin treatment, and history of cardiovascular disease) and for markers of kidney dysfunction and damage (cystatin C–based eGFR and urinary albumin/creatinine ratio). Higher urinary KIM-1/creatinine (from 24-hour urine collections) was associated with a higher risk for cardiovascular mortality (hazard ratio per SD increase, 1.27; 95% confidence interval [95% CI], 1.05 to 1.54; P=0.01). Participants with a combination of high KIM-1/creatinine (upper quintile, ≥175 ng/mmol), low eGFR (≤60 ml/min per 1.73 m2), and microalbuminuria/macroalbuminuria (albumin/creatinine ratio≥3 g/mol) had a >8-fold increased risk compared with participants with low KIM-1/creatinine (<175 ng/mmol), normal eGFR (>60 ml/min per 1.73 m2), and normoalbuminuria (albumin/creatinine ratio<3 g/mol) (hazard ratio, 8.56; 95% CI, 4.17 to 17.56; P<0.001).

    Conclusions

    These findings suggest that higher urinary KIM-1 may predispose to a higher risk of cardiovascular mortality independently of established cardiovascular risk factors, eGFR, and albuminuria. Additional studies are needed to further assess the utility of measuring KIM-1 in the clinical setting.

    Soluble TNF Receptors and Kidney Dysfunction in the Elderly2014In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 25, no 6, p. 1313-1320Article in journal (Refereed)
    Abstract [en]

    The importance of TNF-α and its soluble receptors (sTNFR1 and sTNFR2) in the development of kidney disease is being unraveled. Yet, community-based data regarding the role of sTNFRs are lacking. We assessed serum sTNFRs and aspects of kidney damage cross-sectionally in two independent community-based cohorts of elderly participants: Prospective Investigation of the Vasculature in Uppsala Seniors (n=815; mean age, 75 years; 51% women) and Uppsala Longitudinal Study of Adult Men (n=778; mean age, 78 years). Serum sTNFR1 correlated substantially with different aspects of kidney pathology in the Uppsala Longitudinal Study of Adult Men cohort (R=-0.52 for estimated GFR, R=0.22 for urinary albumin-to-creatinine ratio, and R=0.17 for urinary kidney injury molecule-1; P<0.001 for all), with similar correlations in the Prospective Investigation of the Vasculature in Uppsala Seniors cohort. These associations remained significant after adjustment for age, sex, inflammatory markers, and cardiovascular risk factors and were also evident in participants without diabetes. Serum sTNFR2 was associated with all three markers in the Prospective Investigation of the Vasculature in Uppsala Seniors cohort (P<0.001 for all). Our findings from two independent community-based cohorts confirm and extend results of previous studies supporting circulating sTNFRs as relevant biomarkers for kidney damage and dysfunction in elderly individuals, even in the absence of diabetes.

    Soluble Tumor Necrosis Factor Receptor 1 Is Associated with Glomerular Filtration Rate Progression and Incidence of Chronic Kidney Disease in Two Community-Based Cohorts of Elderly Individuals2015In: Cardiorenal Medicine, ISSN 1664-3828, Vol. 5, no 4, p. 278-288Article in journal (Refereed)
    Abstract [en]

    Objective: We aimed to explore and validate the longitudinal associations between soluble tumor necrosis factor receptor 1 (sTNFR1), glomerular filtration rate (GFR) progression, and chronic kidney disease (CKD) incidence in two independent community-based cohorts of elderly individuals with prespecified subgroup analyses in individuals without prevalent diabetes. Research Design and Methods: Two community-based cohorts of elderly individuals were used with 5-year follow-up data on estimated GFR: the Uppsala Longitudinal Study of Adult Men (ULSAM; n = 437 men; mean age: 78 years) and the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; n = 703; mean age: 70 years; 51% women). GFR categories were defined as >= 60, 30-60, and = 60 ml/min/1.73 m(2) at baseline, higher sTNFRs were associated with incident CKD after 5 years in both cohorts [ULSAM: OR per SD increase 1.49 (95% CI 1.16-1.9) and PIVUS: OR 1.84 (95% CI 1.50-2.26)]. Associations were similar in individuals without diabetes. Conclusions: Higher circulating sTNFR1 independently predicts the progression to a worse GFR category and CKD incidence in elderly individuals even in the absence of diabetes. Further studies are warranted to investigate the underlying mechanisms, and to evaluate the clinical relevance of our findings.

    The potential role of miR-126, miR-21 and miR-10b as prognostic biomarkers in renal cell carcinoma2019In: Oncology Letters, ISSN 1792-1074, E-ISSN 1792-1082, Vol. 17, no 5, p. 4566-4574Article in journal (Refereed)
    Abstract [en]

    Renal cell carcinoma (RCC) is the most commonly diagnosed renal tumor, consisting of ~3% of all malignancies worldwide. The prognosis of RCC can vary widely, and detecting patients at risk of recurrence at an early stage of disease may improve patient outcome. The factors presently used in a clinical setting cannot reliably predict the natural history of the disease. Therefore, there is a requirement to identify novel biomarkers that can aid in predicting patient outcome. Previous studies have indicated that microRNAs (miRNAs/miRs) are potential candidates as prognostic biomarkers for patients suffering from RCC. Consequently, the aims of the present study were to validate the potential of 3 of these miRNAs to predict the prognosis of patients with RCC, and to investigate the stability of endogenous control genes for miRNA studies in RCC tissues. The expression of 7 endogenous controls was measured using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in formalin-fixed paraffin-embedded tumor and benign tissues from patients suffering from clear cell RCC (ccRCC). The analyses identified RNU48 and U47 as the most stable endogenous controls. The expression of miR-126, miR-21 and miR-10b was analyzed using RT-qPCR in renal tissues from 116 patients diagnosed with ccRCC. All three investigated miRNAs were differentially expressed between malignant and benign tissues. miR-126 and miR-10b were also differentially expressed between grades and stages of ccRCC. In a univariate, but not in a multivariate model, low expression of miR-126 was associated with shorter time to recurrence of the disease. The results of the present study indicate that of the 3 miRNAs investigated, the expression of miR-126 has the strongest potential as a prognostic biomarker for patients suffering from ccRCC.

    Prostate cancer and inflammation: The role of miRNAs2013In: European Medical Journal Oncology, ISSN 2054-619X, p. 56-60Article, review/survey (Refereed)
    Abstract [en]

    Approximately 15-20% of all human cancers are assumed to be a result of infection and chronic inflammation due to a constant supply of cytokines and reactive oxygen species, giving rise to genomic instability and a subsequent tumour development. In recent years, chronic inflammation has also been hypothesised to influence prostate carcinogenesis, since both acute and chronic inflammation is commonly seen in prostatic tissues. The signalling pathways involved in the immune response and tumour development are overlapping with each other, and it has been proposed that miRNAs are a possible link between the two processes. In this review, we are describing some of the miRNAs which could constitute a conceivable link between inflammation and prostate cancer.

    Quantity and quality of nucleic acids extracted from archival formalin fixed paraffin embedded prostate biopsies2018In: BMC Medical Research Methodology, ISSN 1471-2288, E-ISSN 1471-2288, Vol. 18, no 1, article id 161Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: In Sweden, human tissue samples obtained from diagnostic and surgical procedures have for decades been routinely stored in a formalin-fixed, paraffin-embedded, form. Through linkage with nationwide registers, these samples are available for molecular studies to identify biomarkers predicting mortality even in slow-progressing prostate cancer. However, tissue fixation causes modifications of nucleic acids, making it challenging to extract high-quality nucleic acids from formalin fixated tissues.

    METHODS: In this study, the efficiency of five commercial nucleic acid extraction kits was compared on 30 prostate biopsies with normal histology, and the quantity and quality of the products were compared using spectrophotometry and Agilent's BioAnalyzer. Student's t-test's and Bland-Altman analyses were performed in order to investigate differences in nucleic acid quantity and quality between the five kits. The best performing extraction kits were subsequently tested on an additional 84 prostate tumor tissues. A Spearman's correlation test and linear regression analyses were performed in order to investigate the impact of tissue age and amount of tissue on nucleic acid quantity and quality.

    RESULTS: Nucleic acids extracted with RNeasy® FFPE and QIAamp® DNA FFPE Tissue kit had the highest quantity and quality, and was used for extraction from 84 tumor tissues. Nucleic acids were successfully extracted from all biopsies, and the amount of tumor (in millimeter) was found to have the strongest association with quantity and quality of nucleic acids.

    CONCLUSIONS: To conclude, this study shows that the choice of nucleic acid extraction kit affects the quantity and quality of extracted products. Furthermore, we show that extraction of nucleic acids from archival formalin-fixed prostate biopsies is possible, allowing molecular studies to be performed on this valuable sample collection.

    PD-L1 Expression is Associated With Poor Prognosis in Renal Cell Carcinoma2019In: Applied immunohistochemistry & molecular morphology (Print), ISSN 1541-2016, E-ISSN 1533-4058Article in journal (Refereed)
    Abstract [en]

    Programmed death ligand 1 (PD-L1) is a protein which, when interacting with its receptor programmed death 1, acts as a negative regulator of the antitumor T-cell-mediated immune response. The prognostic value of PD-L1 expression in renal cell carcinoma (RCC) has been controversial. In this study, the prognostic value of PD-L1 expression in RCC was evaluated by analyzing PD-L1 immunoreactivity in tumor cells and tumor-infiltrating immune cells (TIICs) in 346 RCC patients with long-term follow-up. PD-L1 positivity in tumor cells was associated with higher World Health Organization nucleolar grade (P<0.001), recurrence (P=0.011), and death due to RCC (P=0.031). PD-L1 positivity in TIICs was associated with higher nucleolar grade (P<0.001), higher T-stage (P=0.031), higher N-stage (P=0.01), recurrence (P=0.007), and death due to RCC (P=0.001). A significant positive association of time to cancer-specific death with both PD-L1-positive tumor cells and TIICs were also found. The data indicate that RCC patients with PD-L1-positive tumor cells and TIICs are at significant risk for cancer progression and the expression may be used as a complementary prognostic factor in the management of RCC patients.

    High Concentrations of the Angiogenic Peptide VEGF-A in Seminal Fluid and its Association to Prostasomes2016In: Clinical Laboratory, ISSN 1433-6510, Vol. 62, no 8, p. 1515-1520Article in journal (Refereed)
    Abstract [en]

    Background: Angiogenesis is the formation of new blood vessels by capillary sprouting from pre-existing vessels. This process is associated with increased expression of angiogenic factors like vascular endothelial growth factor (VEGF). The VEGF family consists of five members denoted VEGF-A, B, C, D and placenta growth factor (PlGF). Prostasomes are exosome-like extracellular vesicles existing in seminal plasma. The present study aimed at investigating the possible relationship between VEGF-A in seminal fluid and blood plasma and the prostasomal association of VEGF-A.

    Methods: Measurement of VEGF-A concentrations was carried out in seminal plasma from 40 males and in blood plasma from 40 male blood donors utilizing commercial ELISA kits. The prostasomal association of VEGF-A was investigated by flow cytometry.

    Results: We found highly elevated concentrations of VEGF-A in seminal fluid (median value 150000 pg/mL) compared with those of blood plasma. Flow cytometric analysis showed that VEGF-A is bound to the surface of prostasomes.

    Conclusions: Prostasomes and seminal plasma contain the angiogenic factor VEGF-A in high concentrations exceeding that of blood plasma by 1000 times.
