ABSTRACT
Uniform treatment based on the therapeutic approach of the 1st and 2nd US National Wilms' Tumor Study was decided on in March 1976 by paediatricians, surgeons, urologists and radiotherapists in Austria. Wilms' tumour was diagnosed in 34 children between 1 january 1976 an 29 february 1980 (stage I: n = 11, stage II: n = 8, stage III: n = 8, stage IV: n = 7). Parents of two children refused treatments; both children have since died of metastases. Of the remaining 32 children 29 (90.6%) are alive, 10 for more than 4, 15 for more than 3 and 19 for more than 2 years after diagnosis. 21 children are without need of treatment. Three children have died, one due to postoperative complications, one due to haemorrhagic chickenpox, but free of tumour, and one after insufficient treatment. Two of the five children with a recurrence between 2 1/4 to 15 months after diagnosis had been treated inadequately in the initial phase. The tumour free survival rate in 74.2%. Two children with early occurring or recurrent lung metastases have survived for 53 1/2 and 54 months up to now.
