Pulmonary disease after treatment for Wilms tumor: a report from the national wilms tumor long-term follow-up study.

Purpose: This study was undertaken to evaluate the incidence of pulmonary disease among patients treated with radiation therapy (RT) for pulmonary metastases (PM) from Wilms tumor (WT).

Patients And Methods: We reviewed records of 6,449 patients treated on National Wilms Tumor Studies-1, -2, -3, and -4 whose flow sheets or annual status reports documented one of several pulmonary conditions. Cases were fully evaluable if pulmonary function test (PFT) results were available, pulmonary fibrosis was identified on a chest radiograph or was listed as the primary or a contributing factor to death.

End stage renal disease in patients with Wilms tumor: results from the National Wilms Tumor Study Group and the United States Renal Data System.

Purpose: We sought to assess accurately the full spectrum of end stage renal disease (ESRD) in Wilms tumor survivors by combining the unique resources of the National Wilms Tumor Study Group (NWTSG) and the United States Renal Data System (USRDS), and to confirm preliminary reports of an increased incidence of ESRD in patients with the Wilms tumor-aniridia syndrome (WAGR).

Materials And Methods: ESRD was ascertained in 5,910 patients enrolled in NWTSG studies during 1969 to 1994 by record linkage to USRDS and by direct followup. Cumulative ESRD incidence was estimated accounting for intercurrent mortality.
