Abstract

The use of partial nephrectomy (PN) to treat patients with large renal cell carcinoma (RCC) remains controversial, particularly among elderly patients. The present study compared the improvement in cancer‑specific survival (CSS) in patients with pT1b RCC who underwent either PN or radical nephrectomy (RN) and investigated the effects of age and sex on CSS. A total of 20,343 patients were identified in the Surveillance, Epidemiology and End Results database. Kaplan‑Meier curves and Cox regression analysis were used to compare the CSS of patients who received PN vs. those who received RN. In total, 5,375 (26.42%) and 14,968 (73.58%) patients with pT1b RCC received PN and RN, respectively. Kaplan‑Meier and Cox regression analysis indicated that PN resulted in an improved CSS compared with RN (P<0.001). In addition, PN was observed to be beneficial in male (P<0.001) and female patients <75 years of age. However, it was not beneficial for female patients of ≥75 years of age (P=0.197). These preliminary results warrant further investigation in clinical trials.
