Abstract:
Objective To compare the clinical outcomes and prognosis of partial nephrectomy (PN) and radical nephrectomy (RN) on pT1bN0M0 renal cell carcinoma (RCC) patients, and to provide reference for treatment selection on pT1b RCC.
Methods We retrospectively analyzed the data of 68 patients (PN=16 cases, RN=52 cases) diagnosed as pT1bN0M0 RCC from January 2004 to December 2010 in Hubei Cancer Hospital. We compared the clinical outcomes including 5-year overall survival (OS), recurrence-free survival (RFS) and cancer-specific survival (CSS) between two groups. We also analyzed renal function by collecting creatinine and estimated glomerular filtration rate(eGFR) before and after the operation.
Results The 5-year OS (90.3% vs. 88.6%, P=0.552), RFS (90.3% vs. 75.4%, P=0.121) and CSS (90.3% vs. 92.8%, P=0.875) between PN and RN groups were not significantly different. The number of patients with a decrease of renal function was fewer in the PN group than that in the RN group (0 vs. 12.6%, P < 0.01). However, the serum creatinine and GFR one year after surgery was not significantly different between two groups (0.2±0.1) vs. (0.3±0.6), P=0.115, (9.8±12.1) vs. (20.1±12.6), P=0.064.
Conclusion There was no significant difference in the clinical outcomes and safety between PN and RN on pT1bN0M0 RCC patients, moreover, postoperative renal function of PN group were better than those of RN group. PN could be an appropriate and safe option for pT1b RCC.
