[Neuroblastoma: prognostic factors and survival. Experience in Hospital de Pediatria del Centro Medico Nacional del Siglo XXI and review of the literature].
Neuroblastoma (NB) is the most frequent extracranial solid tumor in children according to the literature. In Mexico it is less frequent, fallen to 8th place. Our objective was to analyze our experience and compare it with the one reported in other countries. We included all patients admitted to our hospital during the previous five years and who had not received any treatment. Patients with stages I, II, and IV received cyclophosphamide and epirrubicin. Patients with stages were III and IV received the same chemotherapy alternating with cisplatinum., ifosfamide and etoposide during 12 months as well as massive doses of 131-MIBG and surgical ablation of the remaining tumor when possible. We included 30 patients, 25 with initial presentation in the abdomen. Five were in early stages and 20 (70%) were advanced with an overall survival of 100% and 27% at 5 years respectively. When analyzed by age, 40% were 12 months of age and 60% older, with survival of 100% and 27% in the same period, respectively. According to histology there was 91% survival for differentiated and 23% for undifferentiated tumors. The chemotherapeutic regimen reported is effective but not better than that reported by other authors, in which some benefits are seen with use of transplant and immunotherapy. The most important prognostic factors are still considered to be age, stage and histology.
