THE RANK OF THE OPERATIVE TREATMENT IN WI LMS-TUMORS

Over the last 25 years, 74 patients with Wilms' tumor have been treate d at the University Hospital in Mainz. The stage-adapted treatment pla n always involved surgery, and ca. 30 % of the children had undergone preoperative treatment. In 94% (= 75/80) of the operations, complete t umor removal was achieved. In 4 children, subtotal or partial resectio n was possible and in one the tumor proved inoperable. The observation of significant operative complications as high as 20% within the Nati onal Wilms' Tumor Study 3 could not be found.
