title: LAPAROSCOPIC RADICAL NEPHRECTOMY FOR RENAL TUMOR>7CM.
abstract: (Objectives) Laparoscopic radical nephrectomy (LRN) is now a standard care for the treatment of renal tumors, but the limitation of LRN for large tumors remains to be elucidated. In this study, we examined the safety and efficacy of LRN for >7 cm renal tumors including tumors >10 cm. (Patients and methods) From March 2001 to September 2014, 167 patients received laparoscopic surgery for renal tumors at our institution. Of these, 126 patients (≤4.0 cm: 64 cases, 4.1-7.0 cm: 40 cases, 7.1-10.0 cm: 12 cases, >10.0 cm: 10 cases) underwent LRN. Treatment outcomes including surgical and oncological outcomes among each stage were compared. (Results) Operating time for 7.1-10.0 cm tumors were similar to that <7 cm tumors but that for >10 cm tumors was significantly longer than that <10 cm tumors. There was no significant difference among each stage in terms of complication rate. As expected, recurrence-free survival rate for >10 cm tumors were worse than <10 cm tumors. (Conclusions) Our data suggests that LRN for large tumors >7 cm can be performed safely, but LRN for >10 cm tumors are technically demanding and require longer operation time.
