Abstract:
OBJECTIVE:• To investigate the oncological efficacy of retroperitoneal laparoscopic radical nephrectomy (RLRN) compared with transperitoneal laparoscopic radical nephrectomy (TLRN) for the management of clear-cell renal cell carcinoma (RCC). PATIENTS AND METHODS:• With emphasis on survival and disease recurrence, a retrospective analysis was made of 580 patients who underwent TLRN (472 patients) or RLRN (108 patients) at 23 institutions between January 1997 and December 2007. • Inclusion criteria were clear-cell RCC, stage pT1 to pT2 without any nodal involvement, and metastasis. • Overall survival and recurrence-free survival curves were estimated using the Kaplan-Meier method. • To assess the association between the surgical approach and survival outcomes, Cox proportional hazard models were constructed. RESULTS:• The median follow-up was 30 months in the TLRN group and 35.6 months in the RLRN group. Both groups were comparable regarding age, gender, body mass index (BMI), Fuhrman's grade, size of tumours and stage. • Kaplan-Meier curves and the log-rank test showed no significant difference between the TLRN and RLRN groups in 5-year overall (92.6% vs 94.5%; P = 0.669) and recurrence-free survival (92.0% vs 96.2%; P = 0.244). • In a Cox regression model with age, gender, Eastern Cooperative Oncology Group performance status, BMI, nuclear grade and T-stage adjusted variables, no significant difference was found between the two surgical approaches. CONCLUSION:• The present study is the largest oncological analysis for laparoscopic radical nephrectomy (LRN) comparing transperitoneal and retroperitoneal approaches. The data from it provide the objective evidence to suggest similar oncological outcomes for both approaches to LRN.
