In the European Organization for Research and Treatment of Cancer (EORTC) randomized trial 30904, nephron-sparing surgery (NSS) was associated with reduced overall survival compared with radical nephrectomy (RN) over a median follow-up of 9.3 yr (hazard ratio: 1.50; 95% confidence interval [CI], 1.03-2.16).To examine the impact of NSS relative to RN on kidney function in EORTC 30904.This phase 3 international randomized trial was conducted in...
