Primary renal sarcomas in the Intergroup Rhabdomyosarcoma Study Group (IRSG) experience, 1972–2005: A report from the Children's Oncology Group

Abstract

Purpose To describe clinical and pathologic characteristics and outcome of patients with renal sarcomas. Patients/Methods The IRSG database includes newly diagnosed patients Aspergillus pneumonia. The six Group I and II patients survive, continuously disease‐free, at 2.7–17.3 years (median, 4.7 years). Conclusions Patients with renal sarcomas often present with large tumors, many of them containing anaplastic features. Removing all gross disease at diagnosis, if feasible, is a critical component of treatment to curing patients with renal sarcoma. Pediatr Blood Cancer 2008;51:339–343.
