BackgroundGiven the expanding clinical applications of laparoscopic surgery and neoadjuvant chemotherapy in advanced gastric cancer treatment, there is an emerging need to summarize the few evidences that evaluated the safety and efficacy of laparoscopic versus open gastrectomy in patients with advanced gastric cancer (AGC) following neoadjuvant chemotherapy (NAC).MethodsFrom January 1 to 2, 2021, we searched Ovid Embase, PubMed, Cochrane central register Trials (Ovid), and web of science to find relevant studies published in English, and two authors independently performed literature screening, quality assessment of the included studies, data extraction, and data analysis. This study was registered with PROSPERO (CRD42021228845).ResultsThe initial search retrieved 1567 articles, and 6 studies were finally included in the meta-analysis review, which comprised 2 randomized control trials and 4 observational studies involving 288 laparoscopic gastrectomy (LG) and 416 open gastrectomy (OG) AGC patients treated with NAC. For intraoperative conditions, R0 resection rate, blood transfusion, intraoperative blood loss, number of lymph nodes dissected, proximal margin, and distal margin were comparable between LG group and open OG group. For postoperative short-term clinical outcomes, LG has significantly less postoperative complications (OR = 0.65, 95%CI: 0.42–1.00, p = 0.05) and shorter postoperative time to first aerofluxus (WMD = -0.57d, 95%CI: -0.89–0.25, p = 0.0004) than OG, and anastomotic leakage, pulmonary infection, pleural effusion, surgical site infection, thrombosis, intestinal obstruction, peritoneal effusion or abscess formation, postoperative time to first defecation, postoperative time to first liquid diet, and postoperative length of stay were comparable between the two groups. For postoperative survival outcomes, there were no significant differences in disease-free survival (DFS) and overall survival (OS) between the two groups.ConclusionThe available evidences indicated that LG is an effective and feasible technology for the treatment of AGC patients treated with NAC, and LG patients have much less postoperative complications and faster bowel function recovery than OG patients.Systematic Review RegistrationPROSPERO database (identifier, CRD42021228845).

e15503 Background: Locally advanced gastric cancer (LAGC) has a poor prognosis. Neoadjuvant chemotherapy can reduce tumor loading, degrade staging and increase possibility of complete resection, thus prolonging the survival of LAGC patients (pts). We conducted a phase II trial to assess the feasibility of SOX regimen in combination with apatinib (an anti-angiogenic agent) as neoadjuvant therapy in LAGC. Methods: This study recruited untreated LAGC pts with pathologically and/or cytologically confirmed adenocarcinoma. Treatment included three 21-day cycles of apatinib (oral, 500 mg qd; discontinued in the last cycle), S-1 (oral, 40-60 mg, bid, day 1-day 14) and oxaliplatin (iv, 130 mg/m2, day 1), followed by radical surgery after 4 weeks. The primary outcome was neoadjuvant therapy related toxicity, and the secondary outcomes included tumor response, R0 resection rate, postoperative pathological evaluation and surgical morbidity. Results: Between December 2, 2016 and August 1, 2018, 31 patients were enrolled. Total 29 patients were eligible for safety and efficacy analyses of SOXA as NAC. During NAC treatment, the incidence of adverse events (AEs, any grade) was 100%, and the incidence of grade 3/4 AEs was 34.48%. No treatment-related death. The ORR of 79.31% (95%CI, 60.28-92.01%) and DCR of 96.55% (95%CI, 82.24-99.91%) were achieved. One patient was evaluated as PD with hepatic metastasis after 3 cycles of preoperative chemotherapy, and this case was inoperable. Resection with curative intent was undertaken in 28 patients with R0 resection rate of 100%. Operative morbidity was observed in 12 of 28 patients including fever (9, 32.14%), anastomotic leakage (1, 3.57%), fat liquefaction of post-surgical incision (1, 3.57%), and gastroparesis (1, 3.57%). Additionally, after surgery 1 patient had pulmonary infection and 1 patient had pleural effusion. The median tumor regression was 90% on pathological findings after surgery. Conclusions: Neoadjuvant therapy with apatinib plus SOX for LAGC showed acceptable toxicity and promising efficacy.
