Abstract:
166 Background: We introduced laparoscopy-assisted distal gastrectomy (LADG) as multi-institutional feasibility study, and already reported that the overall morbidity rate was 1.6% in the study (Gastric Cancer 2012). The aim of this study is to evaluate the long-term survival results of the patients who were enrolled to the study and finished 5-year follow-up. Methods: A total of 165 c-stage I gastric cancer patients who were registered from Kanagawa Cancer Center were included to the study. The Kaplan-Meier method was used to evaluate overall survival and recurrence-free survival. Results: Median follow-up period of the patients was 1901 days. The reconstruction methods were either B-I (n=150), R-Y (n=14), or B-II (n=1). The accuracy for preoperative diagnosis of stage I was 87.2% (144/165). Among 14 patients with p-stage II/III excluding T3N0/T1N2-3, eight patients received postoperative adjuvant chemotherapy. The recurrence rates by pathological stage were 0% (0/123) for stage IA, 4.7% (1/21) for stage IB, 6.2% (1/16) for stage II, and 60% (3/5) for stage III/IV, respectively. The organ of recurrence was mainly observed in liver (n=3), followed by bone, lymph node, peritoneum (n=1). The 5-year recurrence-free survival rates were 94.5% for all patients, 97.2%/92.3%/60% for pT1/pT2/pT3/4, 98.5%/82.4%/71.4%/66.7% for pN0/pN1/pN2/pN3, 97.9%/81.3%/40% for p-stage I/p-stage II/p-stage III/IV. Conclusions: LADG for c-stage I gastric cancer was feasible in long-term result, as well as in short-term outcome.
