Laparoscopic nephron sparing surgery and radical nephrectomy in cT1 renal tumors. Comparative analysis of complications and survival.

INTRODUCTION AND OBJECTIVES Comparative analysis of postoperative complications and survival between laparoscopic partial nephrectomy (PN) and radical nephrectomy (RN) in cT1 renal cell carcinoma (RCC). MATERIAL AND METHOD Retrospective study of patients with two kidneys and single renal tumor cT1 treated in our center between 2005 and 2018 by laparoscopic PN or RN. RESULTS 372 patients met the inclusion criteria for the study. RN was performed in 156 (41.9%) patients and PN in 216 (58.1%). Clavien Dindo III-V complications were observed in 10 (4,6%) PN and 6 (3,9%) RN patients (p = 0.75). The comorbidity Charlson index (CCI) was identified as an independent predictor variable of complications (p = 0.02) and surgical approach did not affect multivariate analysis. Estimated overall survival (OS) was 81.2% and 56.8% at 5 and 10 years in the RN group and 90.2% and 75.7% in the PN group, respectively (p = 0.0001). Obesity (HR 2.77, p = 0.01), CCI ≥ 3 (HR 3.69, p = 0.001) and glomerular filtration rate (GFR) <60 mL/min/1.73 m2 at discharge (HR 1.87, p = 0.03) were identified as predictors of overall mortality. Nephrectomy approach showed no influence on OS. Estimated recurrence-free survival (RFS) was 86.1% at 5 and 10 years in the RN group and 93.5% and 83.6% in the PN group, respectively (p = 0.22). CONCLUSIONS Laparoscopic PN is not inferior to RN in terms of oncologic and surgical safety in cT1 RCC. Nephrectomy approach did not influence patient OS, however, obesity, CCI ≥ 3 and GFR <60 mL/min/1.73 m2 at discharge did behave as predictors.
