Abstract [en]

Neuroblastoma is one of the most enigmatic solid tumors for scientists and pediatric oncologists. Neuroblastoma is primary a childhood form of cancer, consisting of neuroectodermal cells that originate from the neural crest and is destined for the  adrenal medulla and sympathetic nervous system. The Neuroblastoma group at The University of Gothenburg received formalin-fixed paraffin-embedded  tumor samples from Vietnam and this project was to examine if the quality of the DNA from, is good enough to run comparative genome hybridization array experiment  on by using a cheaper technique Multiplex  Ligation-dependent Probe Amplification   technique. Multiplex Ligation-dependent Probe Amplification (MRC Holland) is a multiplex PCR method that can detect abnormalities such as deletions and amplifications. By using probes consisting of one short synthetic arm with a PCR primer sequence Y at the 3´end, and one long probe with a stuffer sequence, and a PCR primer sequence X at the 5´end that can hybridize and ligate. If these probes ligate it is possible to amplify them by PCR just using specific primers for the X and Y sequences. The resulting amplification products can then be analyzed bycapillary electrophoresis. These patient that the DNA was derived from had all stage 4  neuroblastoma, and that is why they all present many aberrations. Among the fascinating data from this experiment, there are many patients with both 11q  deletions and has an extreme amplification of MYCN. In Sweden only a few cases has been discovered. In this material even though all patients are stage 4 patients, 16 have this combination.
