Abstract
The preliminary results of a controlled clinical trial organized by the S.I.O.P. of radiotherapy and chemotherapy in patients with nephroblastoma are presented. Forty-two centers have participated. Between September 1971 and October 1974, 398 patients were registered; 195 were eligible for the trial and were randomized. The remaining 203 patients were excluded from the trial, but were followed in the same way as the patients in the trial. The results were evaluated in terms of recurrence-free survival rate and survival rate. Results in patients who received preoperative and postoperative radiotherapy (group A, 73 patients) were compared with the results in patients who recieved only postoperative radiotherapy (group B, 64 patients). The tumor ruptured at surgery in three patients of group A, and in 20 patients of group B, a difference that is statistically significant. No significant difference in survival and recurrence-free survival between groups A and B is observed at present. Results in patients treated with a single course of actinomycin D (group I, 80 patients) were compared with the results in patients treated with multiple courses (group II, 80 patients). At present, no significant difference is found between the two groups.This publication has 4 references indexed in Scilit:
