Neuroblastoma (NB) is an embryonal tumour of neuroectodermal cells, and its prognosis is based on patient age at diagnosis, tumour stage and MYCN amplification, but it can also be classified according to their degree of methylation. Considering that epigenetic aberrations could influence patient survival, we studied the methylation status of a series of 17 genes functionally involved in different cellular pathways in patients with NB and their impact on survival. We studied 82 primary NB tumours and we used methylation-specific-PCR to perform the epigenetic analysis. We evaluated the putative association among the evidence of hypermethylation with the most important NB prognostic factors, as well as to determine the relationship among methylation, clinical classification and survival. CASP8 hypermethylation showed association with relapse susceptibility and, TMS1 and APAF1 hypermethylation are associated with bad prognosis and showed high influence on NB overall survival. Hypermethylation of apoptotic genes has been identified as a good candidate of prognostic factor. We propose the simultaneous analysis of hypermethylation of APAF1, TMS1 and CASP8 apoptotic genes on primary NB tumour as a good prognostic factor of disease progression.
