Abstract:
122 Background: The efficacy of laparoscopic D2 gastrectomy for the treatment of advanced gastric cancer (AGC) with curative intent is still controversial. Thus, the Chinese Laparoscopic Gastrointestinal Surgery Study (CLASS) group conducted a multicenter prospective randomized controlled trial, aiming to evaluate the surgical safety and long-term outcomes of laparoscopic D2 gastrectomy compared with conventional open surgery for AGC. (NCT01609309) Methods: The patients with tumor located at distal stomach at clinical T2-4a, N0-3, M0 stage were eligible for enrollment, treated by either laparoscopic D2 distal subtotal gastrectomy (LG) or open D2 gastrectomy (OG) after randomization. Seventeen institutions currently participated in the study. The morbidity and mortality within postoperative 30 days were compared between the two groups. Results: A total of 607 consecutive eligible patients were randomly assigned to either LG group (n=308) or OG group (n=299) between September 2012 and January 2014. The compliance rates of D2 lymphadenectomy in the LG group and OG group were similar (97.4% vs. 98.3%; P=0.591). Open conversion rate was 4.5%. There was no significant differences between the LG group and OG group in the incidence of intraoperative complication (5.8% vs. 4.3%; P=0.402), postoperative morbidity (18.8% vs. 14.7%; P=0.175), and mortality (0.6% vs. 0; P=0.499). The severity grade pattern was also similar according to the Clavien-Dindo classification (P=0.372). Conclusions: Laparoscopic D2 distal subtotal gastrectomy for AGC could be safely performed by experienced surgeons. Thus, our multicenter prospective study on long-term outcomes can be ongoing. Clinical trial information: NCT01609309.
