Background The Extensive Intraoperative Peritoneal Lavage (EIPL) has been proposed as a practical prophylactic strategy to decrease the risk of peritoneal metastasis in gastric cancer. Objective To explore the safety and efficacy of the EIPL in our locally advanced gastric cancer patients. Methods This study is an open-label, double-center, single-arm phase II clinical trial developed at two tertiary hospitals from Recife (Pernambuco, Brazil). Results The study protocol was prematurely closed due to slow accrual after only 16 patients had been recruited to participate. Eight of them were excluded of the protocol study during the laparotomy, whereas four cases were also excluded from the per-protocol analysis. Two patients had died in hospital before 30 days and six were alive with no evidence of cancer relapses after a follow-up ranging from five to 14,2 months (median of 10.6 months). In the intention-to-treat analysis, three of eight patients suffered of gastrointestinal leakages and two of them had died. On a per-protocol basis, two of four patients presented this type of postoperative complication and one of them had died. All deaths occurred as a somewhat consequence of gastrointestinal leakages. Conclusion We could not make any conclusion about the safety and efficacy of the EIPL, but the possibility of this approach might increase the rate of gastrointestinal leakage is highlighted.

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.

81 Background: The aim of this study was to evaluate the efficacy and safety of neoadjuvant chemotherapy with the mFOLFOX6 regimen in gastric cancer patients. Methods: This study was a single-arm phase II study. 73 patients with histologically confirmed locally advanced gastric cancer (T2-T4 or N+) were enrolled. The patients were administered the mFOLFOX6 regimen for 3 cycles. Surgery was scheduled 3-4 weeks after the completion of the chemotherapy. Postoperative chemotherapy began 4 weeks after surgery, and the program choice was based on the results of patients’ clinical/pathological evaluations. Perioperative efficacy, toxicity, effects of surgery, postoperative observation, and prognosis were studied. Survival analysis was performed to identify the relationship between the response and outcome and to identify factors predictive of OS. Results: 73 patients received the neoadjuvant chemotherapy, and 67 (91.8%) completed all of the preoperative cycles, with grade 3-4 toxicity arising in 33.0%. Surgery was performed in 71 (97.3%) patients, and radical resection was achieved in 67 (91.8%) patients. Postoperative chemotherapy started in 63 (88.7%) patients. The radiology response rate of chemotherapy was 45.8%. Among the patients who underwent radical surgery, pT downstaging was observed in 22 (32.8%) patients and pN downstaging was observed in 17 (25.4%) patients. All of the patients showed different levels of histological regression of the primary tumour, with a ≥ 50% regression rate of 49.2% and a pCR rate of 3.0%. Univariate analysis identified factors that were associated with OS, including local tumour infiltration, Lauren classification, pre-chemotherapy N stage, ypTNM stage, and pathologic regression rate (GHR)( ≥ 2/3/ < 2/3, ≥ 50%/ < 50%). Multivariate analysis identified both ypTNM stage and Lauren classification as independent predictors of survival. Conclusions: The mFOLFOX6 regimen was very effective and well-tolerated as a neoadjuvant chemotherapy for locally advanced gastric cancer. The ypTNM stage could serve as an independent predictor of survival. GHR ≥ 50% / < 50% could be used as a surrogate marker to guide the selection of a postoperative chemotherapy regimen.
