e16019 Background: Postoperative adjuvant chemotherapy is commonly given after the curative resection of gastric cancer (GC) in both Eastern and Western countries. Several studies have investigated the feasibility and safety of S-1 plus docetaxel or S-1 plus cisplatin. However, the best choice of adjuvant treatment for patients with gastric cancer is still debated. Apatinib, an oral small molecular of VEGFR-2 TKI, has been confirmed to improve OS and PFS with acceptable safety profile in patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy. In this study, we aimed to evaluate the efficacy and safety of apatinib combined with S-1/docetaxel for locally advanced gastric cancer (T3-4aN+M0). Methods: This is a prospective, randomized, controlled, multicenter clinical study. Patients with locally advanced gastric cancer, pathological stage T3-4aN+M0 who underwent D2 lymphadenectomy without prior anti-cancer therapy were included. All these patients were assigned to group A or B. Patients in group A received 6 cycles (21 days a cycle) of adjuvant therapy using S-1 (80-120mg/d, d1-14), and docetaxel (40mg/m2, d1). Group B received the same regimen with the addition of apatinib (250mg, qd.). The primary endpoint was disease-free survival (DFS). The final analysis cutoff date was 30 November, 2020. Results: A total of 45 patients were enrolled from January 2019 to November, 2010 and assigned to group A (21) or group B (24). The DFS was not reached in both of the groups. The 1-year disease-free survival rate was 60% in group A and 90% in the group B, while the difference was not significant. The main AEs in group A were anemia (55%), nausea (50%) and neutropenia (40%); The most common AEs in group B were anemia (45%) neutropenia (40%) and diarrhea (25%). There were no treatment-related deaths. The longest administered time of apatinib with no progression was 457 days. And the median time to receive apatinib was 329 days. Conclusions: Combination of apatinib with S-1/docexal chemotherapy shows clinical benefits in locally advanced gastric cancer (T3-4aN+M0), with tolerable toxicity. The study is still ongoing to reach our final endpoint, DFS. Clinical trial information: ChiCTR2000038900.

AbstractWhether extensive intraoperative peritoneal lavage (EIPL) after gastrectomy is beneficial to patients with locally advanced gastric cancer (AGC) is not clear. This phase 3, multicenter, parallel-group, prospective randomized study (NCT02745509) recruits patients between April 2016 and November 2017. Eligible patients who had been histologically proven AGC with T3/4NxM0 stage are randomly assigned (1:1) to either surgery alone or surgery plus EIPL. The results of the two groups are analyzed in the intent-to-treat population. A total of 662 patients with AGC (329 patients in the surgery alone group, and 333 in the surgery plus EIPL group) are included in the study. The primary endpoint is 3-year overall survival (OS). The secondary endpoints include 3-year disease free survival (DFS), 3-year peritoneal recurrence-free survival (reported in this manuscript) and 30-day postoperative complication and mortality (previously reported). The trial meets pre-specified endpoints. Estimated 3-year OS rates are 68.5% in the surgery alone group and 70.6% in the surgery plus EIPL group (log-rank p = 0.77). 3-year DFS rates are 61.2% in the surgery alone group and 66.0% in the surgery plus EIPL group (log-rank p = 0.24). The pattern of disease recurrence is similar in the two groups. In conclusion, EIPL does not improve the 3-year survival rate in AGC patients.

PURPOSE It is unclear whether laparoscopic distal gastrectomy for locally advanced gastric cancer is oncologically equivalent to open distal gastrectomy. The noninferiority of laparoscopic subtotal gastrectomy with D2 lymphadenectomy for locally advanced gastric cancer compared with open surgery in terms of 3-year relapse-free survival rate was evaluated. PATIENTS AND METHODS A phase III, open-label, randomized controlled trial was conducted for patients with histologically proven locally advanced gastric adenocarcinoma suitable for distal subtotal gastrectomy. The primary end point was the 3-year relapse-free survival rate; the upper limit of the hazard ratio (HR) for noninferiority was 1.43 between the laparoscopic and open distal gastrectomy groups. RESULTS From November 2011 to April 2015, 1,050 patients were randomly assigned to laparoscopy (n = 524) or open surgery (n = 526). After exclusions, 492 patients underwent laparoscopic surgery and 482 underwent open surgery and were included in the analysis. The laparoscopy group, compared with the open surgery group, suffered fewer early complications (15.7% v 23.4%, respectively; P = .0027) and late complications (4.7% v 9.5%, respectively; P = .0038), particularly intestinal obstruction (2.0% v 4.4%, respectively; P = .0447). The 3-year relapse-free survival rate was 80.3% (95% CI, 76.0% to 85.0%) for the laparoscopy group and 81.3% (95% CI, 77.0% to 85.0%; log-rank P = .726) for the open group. Cox regression analysis after stratification by the surgeon revealed an HR of 1.035 (95% CI, 0.762 to 1.406; log-rank P = .827; P for noninferiority = .039). When stratified by pathologic stage, the HR was 1.020 (95% CI, 0.751 to 1.385; log-rank P = .900; P for noninferiority = .030). CONCLUSION Laparoscopic distal gastrectomy with D2 lymphadenectomy was comparable to open surgery in terms of relapse-free survival for patients with locally advanced gastric cancer. Laparoscopic distal gastrectomy with D2 lymphadenectomy could be a potential standard treatment option for locally advanced gastric cancer.

Abstract Background: peri-operative chemo-radiotherapy played important role in locally advanced gastric cancer. Whether preoperative strategy can improve the long-term prognosis compared with postoperative treatment is unclear. The study purpose to compare long-term oncologic outcomes in locally advanced gastric cancer patients treated with preoperative chemo-radiotherapy (pre-CRT) and postoperative chemo-radiotherapy (post-CRT). Methods: From January 2009 to April 2019, 222 patients from 2 centers with stage T3/4 and/or N positive gastric cancer who received pre-CRT and post-CRT were included. After propensity score matching (PSM), comparisons of local regional control (LC), distant metastasis-free survival (DMFS), disease-free survival (DFS) and overall survival (OS) were performed using Kaplan-Meier analysis and log-rank test between pre- and post-CRT groups.Results: The median follow-up period was 30 months. 120 matched cases were generated for analysis. Three-year LC, DMFS, DFS and OS for pre- vs. post-CRT groups were 93.8% vs. 97.2% (p=0.244), 78.7% vs. 65.7% (p=0.017), 74.9% vs. 65.3% (p=0.042) and 74.4% vs. 61.2% (p=0.055), respectively. Pre-CRT were significantly associated with DFS in uni- and multi-variate analysis. Conclusion: Preoperative CRT showed advantages of long-term outcome compared with postoperative CRT.
