Treatment of childhood neuroblastoma at the Clinic of Pediatric Oncology of the Faculty Hospital in Prague during 1965-1982.

The results of a complex treatment of 93 patients with neuroblastoma treated at the Clinic of Pediatric Oncology in Prague during the period of 1965-1982 are presented. A group of 41 patients treated during 1965-1977 was compared to that of 52 patients treated during 1978-1982. The latter group received a more intense chemotherapy treatment. In Group A there survived 7 patients (16.28%), all of them without symptoms of neuroblastoma. In Group B did so 31 patients (59.61%), 25 of them (48.08%) without symptoms of the disease, however, the results obtained in this group are of rather recent origin. A comparison made by means of the log-rank test and by extrapolating the data from curves of survival rates revealed no statistically significant improvement.
