Abstract:Objective: To determine the feasibility and efficacy of laparoscopic tumor enucleation (LTE) for T1aN0M0 renal cell carcinoma (RCC). Methods: From October 2006 to October 2012, a total of 179 patients who underwent laparoscopic nephron sparing surgery for T1aN0M0 RCC were divided into two groups according to the theray procedures. The patients in group A, including 94 patients, were treated by LTE, and those in group B, including 85 patients, were subjected to laparoscopic partial nephrectomy (LPN). The efficacy was evaluated by comparing demographic, intraoperative, postoperative, histopathologic and follow-up data. Results: There were no significant differences in age, gender, the greatest tumor diameter, the mean operation time, the rate of clamping the renal artery, the warm ischemia time between two groups (P>0.05). The intraoperative blood loss, the rate of intraoperative blood transfusion, the rate of complications and the hospital stay after operation in group A were significantly decreased as compared with group B (P<0.05). One patient in group A and 3 patients in group B had positive surgical margins, and 22 patients in group A and 27 patients in group B had pseudocapsule with signs of penetration (P>0.05). During the postoperative follow-up period with a mean of (33.5±20.9) months, local recurrence alone elsewhere in the kidney was observed in 1 patient of the two groups respectively. One patient had local recurrence while another one had single lung metastasis in group B. There were no significant differences in the recurrence rate and transfer rate between the two groups (P>0.05). Conclusions: LTE has the similar oncologic outcome compared to LPN for T1aN0M0 RCC, with a better reserved renal function, and decreased rate of complications.
