Abstract

Background Although many reports have indicated the feasibility of laparoscopic gastrectomy (LG) regarding short-term surgical outcomes, the role of LG remains controversial because studies of long-term outcomes of LG are insufficient. The purpose of this study was to evaluate the long-term oncologic outcomes of patients who have undergone LG. Methods Between May 2003 and December 2009, 714 consecutive patients underwent LG for gastric cancer. After excluding operative mortality (n = 4) and a case of Krukenberg tumor that was not identified at the time of surgery (n = 1), a total of 709 patients were analyzed for long-term oncologic outcomes. Gastric cancer cases were analyzed according to the American Joint Committee on Cancer classification (seventh edition). Overall survival and relapse-free survival were estimated by using the Kaplan-Meier method. Results Median follow-up was 46.2 months. Postoperative recurrence was observed in 26 patients (3.7%). The instances of recurrence were as follows: seven peritoneal, six locoregional, five hematogenous, four distant lymph nodes, and four mixed recurrence. There were neither portsite nor wound site metastases. The 5-year relapse-free survival rates were: 95.8% in stage I, 83.4% in stage II, and 46.4% in stage III. Five-year overall survival rates were: 96.4% in stage I, 83.1% in stage II, and 50.2% in stage III. The independent risk factors for recurrence were T stage and N stage. For survival, age, T stage, and N stage were statistically independent prognostic factors Conclusions Our single-center study of a large patient series revealed that LG for gastric cancer had acceptable long-term oncologic outcomes comparable to those of conventional open surgery.
