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. Clinical trial information: NCT02226380.

122 Background: Previous phase II trial with combination therapy of S-1 plus oxaliplatin (SOX) demonstrated high response rate and well tolerability in patients with untreated advanced gastric cancer. The aim of this phase II trial was to evaluate the efficacy and safety of SOX as neoadjuvant chemotherapy for locally advanced gastric cancer (AGC). Methods: Eligibility criteria included a histologically proven AGC with stage IIIb, IIIc (AJCC 7th edition), at least 1 measurable lesion, no prior chemotherapy, ECOG 0∼2, adequate hepatic, renal, and bone marrow function. Enrolled patients were staged by EUS and CT. The neoadjuvant chemotherapy consisted of 3-4 cycles of oxaliplatin (130 mg/m2) on day 1 and S-1 (80 mg/m2/day) for 14 days with 7 days rest. After chemotherapy, the patients underwent surgery. Results: From Dec 2009 to Sep 2010, 35 patients (IIIb; 19pts, IIIc; 16pts) were enrolled. The median age of the patients was 54.6 years (range; 20-72 y). All patients were available for evaluating the clinical responese and adverse events. The overall response rate was 68.5% (1CR, 23 PR, 9 SD, 2 PD). 32 patients underwent surgical resection. Of them, 27 patients underwent standard D2 surgery and 5 patients had palliative surgery. 25 patients had R0 resection. Postoperative pathological examination showed that most of the surgical patients were in T4a stage. According to Lauren classification, 71.9% patiens (23/32pts) were diffuse type, SOX showed higher respons rate (1CR, 20 PR, 2 SD, RR: 91.3%) among these patients. Major grade 3/4 hematological toxicities were anemia (5.7%), neutropenia (5.7%) and liver dysfunction (8.6%) and non-hematological toxicities were anorexia (5.7%) and vomiting (11.4%). But most of the adverse events were managable. Conclusions: Neoadjuvant chemotherapy with S-1 plus oxaliplatin (SOX) showed high response rate and and R0 resection rate for locally advanced GC, especially for diffuse type patients. All the patients did not have severe toxicity during the process of chemotherapy. This is the preliminary results, and the survival benefit in locally advanced GC patients that respond to SOX neoadjuvant chemotherapy needs to be addressed by a randomized-controlled trial. No significant financial relationships to disclose.

4095^ Background: Perioperative chemotherapy (CT) has demonstrated as survival benefit in locally advanced gastric cancer (GC) in randomized trials. However, the overall cure rate is 30-40% and a significant number of patients are not able to receive the postoperative part of their CT regimen. In Europe, the trifunctional antibody catumaxomab is approved for the treatment of malignant ascites based on a pivotal trial which also included GC patients. A new multimodal approach combining neoadjuvant CT, followed by gastrectomy and intraperitoneal (i.p.) immunotherapy with catumaxomab was assessed in a single-arm multicenter phase II study. We here report 2-year follow-up data. Methods: GC pts (T2/T3/T4, N+/–, M0) received 3 cycles of neoadjuvant fluoropyrimidin/platinum-based CT followed by ’en-bloc’ R0-gastrectomy. Catumaxomab was administered i.p. as intraoperative bolus (10 µg) followed by 4 consecutive 3-hour infusions of 10-150 µg. Primary safety endpoint was the rate of predefined postoperative complications observed during 30 days after surgery. Key efficacy endpoints included disease-free (DFS) and overall survival (OS). Results: The original study data presented at the WCGC in 2011 (Schuhmacher et al.,Ann Oncol (2011) 22(suppl. 5)) showed that the primary endpoint was met and the described application regimen is safe. At time of surgery, 27.8% of patients were stage I, 27,8% of patients were stage II, 22,3% of patients were stage III and 14,8% of patients were stage IV as assessed according to pTNM measures. At 24 months 39/54 (safety analysis set) patients were still alife,14/54 were dead, (one patient lost to follow-up), 24/37 had no progression, only 13/37 patients relapsed (for 2 patients disease status was not recorded). At the 2 year cut off DFS was 56.4% (95% CI: 41–69%), OS was 75% (95% CI: 60–85%). Conclusions: Catumaxomab as part of a multimodal therapy in primarily resectable GC is a feasible option. The 2-year follow up efficacy results show promising data for DFS and OS in a cohort of locally advanced gastric cancer pts.
