136 Background: Gastric cancer is a worldwide common malignant disease with a high mortality rate. Adjuvant chemotherapy did not result in a survival advantage in Caucasian populations. Therapeutic chemotherapy options consist of either monotherapy or of polychemotherapy and have been applied as neoadjuvant chemotherapy with combinations of epirubicin, cyclophosphamide and 5-fluorouracil or capecitabine as well as cisplatin or oxaliplatin. The aim of this retrospective analysis was to investigate the use of the EOX regimen in the neoadjuvant setting which had shown activity in advanced gastric cancer. Methods: 23 patients (pts) (median age: 70, range 36-85, years; 16 pts >65 years) with locally advanced adenocarcinoma of the upper GI-tract received 3 courses of preoperative chemotherapy with epirubicin 50 mg/m2, day1, oxaliplatin 130 mg/m2, day 1, and capecitabine 2,000 mg/m2, days 1-14, of a 3-week cycle. Toxicity was assessed by CTC (Common Toxicity Criteria) after every cycle. Progression free survival (PFS) was defined as time from surgery to disease progression assessed by PET-CT which was performed at diagnosis and after 3 cycles chemotherapy. Results: 20 pts completed all three planned cycles of preoperative chemotherapy, 2 pts received only 1 cycle because of rapid tumor progression and 1 pt. is currently still on treatment. 16 pts. underwent surgery with curative resection with 2 pCRs on pathological review. 6 pts. remained inoperable despite chemotherapy and 1 pt is currently scheduled for surgery. After surgery, 2 pts. died after a median of 9 months (8-10). 4 pts. died without surgery due to disease progression. After a median follow-up of eight months (range 5-26), median PFS and overall survival was not reached yet. In 2 pts., grade 3-4 toxicities including nausea, diarrhea and hand-foot syndrome and one non-life-threatening pulmonary embolism occurred. Conclusions: In summary, EOX is a well tolerated, safe, and efficacious neoadjuvant treatment in also elderly patients with locally advanced adenocarcinoma of the upper GI-tract. However, more studies with a larger population are needed to corroborate the current results of this promising treatment schedule. [Table: see text]

206 Background: Neoadjuvant chemotherapy (NACT) has became the standard approach for patients with advanced gastric cancer. Clinicopathological characteristics can be utilized to evaluate the effect of NACT, and may be a useful tool to identify responsive patients. Methods: We retrospectively reviewed all patients with GC treated with NACT and R0 resection between 2009 and 2015 from a prospective collected database. Histopathological response to the treatment was graded from 0% to 100% and the clinicopathological characteristics assessed to identify predictors of tumor response. A threshold of 50% histopathological response was used for the analysis. Results: NACT was performed in 45 patients. Cisplatin-irinotecan therapy was used in 64.4% of patients and 11 (24.4%) tumors were located in the proximal stomach. Ten (22.2%) patients demonstrated a tumor regression of at least 50% and one patient had complete response. The mean number of lymph node retrieved was 38.1 and 66.7% patients had lymph node metastasis (LNM). Factors associated with > 50% of response by univariate analyses included lower neutrophil-lymphocyte ratio (NLR) ( p = 0.035), diffuse/mixed Lauren type ( p = 0.007), lower depth of tumor invasion ( p = 0.043) and non cisplatin-irinotecan therapy (p = 0.01). A slight tendency of poorly differentiated tumors respond better to NACT than differentiated type was observed ( p = 0.05). There was no significant difference regarding the presence of mucin, calcification and/or necrosis and the tumor response. Multivariate analysis identified NLR and diffuse/mixed tumors as independent predictors of pathologic response. Median follow-up for all patients was 26.5 months and recurrence-free survival (RFS) rate was 74.3% and 60% for patients with > 50% and < 50% of response, respectively ( p= 0.08). RFS was significantly different in patients without LNM compared to patients who have LNM (100% vs. 55.2%, p = 0.01), and in patients with fibroinflammatory/inflammatory stroma infiltration compared to patients with only fibrotic stroma (80% vs. 53.3%, p = 0.015). Conclusions: Diffuse/mixed histopathological type and lower NLR are independently predictors of tumor response after NACT.

351 Background: TAS-118 is a novel oral agent, containing S-1 and leucovorin. In the SOLAR study (NCT02322593), TAS-118 + oxaliplatin (OHP) significantly improved overall survival compared to S-1 + cisplatin for patients (pts) with advanced gastric cancer (GC). We conducted this open-label study to assess feasibility of perioperative adjuvant chemotherapy with TAS-118 + OHP in pts with locally advanced resectable GC with lymph node metastasis. (Clinical trial information: UMIN000024688). Methods: Eligible pts who had histopathologically confirmed GC with clinical T3-4N1-3M0 on image findings (14th Japanese classification of gastric carcinoma), age 20 to 79 years, were enrolled in this study. The protocol treatment consisted of preoperative 4 courses of TAS-118 (80-120 mg/body, days 1-7) + OHP (85 mg/m2, day 1) every 2 weeks, and gastrectomy with D2 lymphadenectomy, followed by postoperative 12 courses of TAS-118 alone (step1) or 8 cycles of TAS-118 + OHP (step2). The primary endpoints were tolerability of preoperative chemotherapy, gastrectomy and postoperative chemotherapy with TAS-118 plus OHP. Here, we report the feasibility of preoperative chemotherapy and gastrectomy, and pathological response. Results: Between December 2016 and April 2018, 45 pts with a median age of 61 years were enrolled. The numbers of pts with T stage (cT3/4a) and those with N stage (cN1/2/3) were 13/32 and 25/17/3, respectively. The completion rate of preoperative chemotherapy and gastrectomy was 88.9% ( 95% CI 78.0-95.5) and 95.6% (95% CI 86.7-99.2). The relative dose intensity of TAS-118 and OHP was 86.0% and 90.6%. During the 4 cycles of preoperative TAS-118 + OHP, 2 pts discontinued the treatment due to adverse event (AE). Major grade 3-4 AEs were diarrhea (17.8%) and neutropenia (8.9%). R0 resection rate was as high as 95.6%. One pts experienced grade 4 postoperative bleeding, but no treatment-related death was reported. pCR was achieved in 6/45 pts (13.3%) and other 7 pts (28.9%) showed near complete regression (<10 % residual tumor cells). Conclusions: Preoperative TAS-118 + OHP followed by D2 gastorectomy was well tolerated and showed promising efficacy. Clinical trial information: 000024688.

Introduction. In advanced gastric cancer, preoperative chemotherapy is associated with survival benefit. FOLFIRI has demonstrated promising results in terms of survival and tolerance, especially in patients with poor performance status. Case Presentation. A 59-year-old male, diagnosed with pT4bN2M0 gastric cancer, underwent gastrointestinal anastomosis and three cycles of EOX chemotherapy. Due to disease progression, he was switched to FOLFIRI regimen. After 12 cycles, the patient received a subtotal gastrectomy and D2 lymphadenectomy. Microscopic examination achieved pCR, and the patient has been surviving 34 months without recurrence. No severe toxicities of chemotherapy were recorded. Conclusions. FOLFIRI might be a safe and effective option in neoadjuvant treatment for advanced gastric cancer among patients with poor performance status or progression after first-line chemotherapy.
