[The prognosis of Wilm's tumor in childhood].

: From January 1974 to June 1990 33 children suffering from Wilms' tumor were treated at the Department of Pediatrics of the Magdeburg Medical Academy. The cumulative five year survival rate was 0.87. The treatment regimen depended on age of patient, stage and histological subclassification of tumor. In spite of an impressive reduction of therapy during the observation period the survival rate of patients remained high. Since 1989 the Nephroblastoma study No 9 of the European International Society of Pediatric Oncology has been applied to improve furthermore the treatment by a preoperative chemotherapy in all patients.
