108 Background: An adjuvant chemotherapy with S-1 has become the standard treatment for patients (pts) with stage II/III gastric cancer (GC) who have undergone gastrectomy with D2 dissection in Japan, but it is assumed that the survival benefit for stage III pts who received S-1 is modest. S-1 plus docetaxel has shown that the response rate and median overall survival (OS) were 56% and 14.3 months in pts with advanced GC. The aims of this phase II study were to evaluate the feasibility and safety of adjuvant S-1 plus docetaxel in pts with stage III GC with D2 surgery. Methods: Pts with pathological stage III GC who underwent gastrectomy with D2 dissection received oral S-1 (80 mg/m2/day) administration for 2 consecutive weeks and intravenous docetaxel (40 mg/m2) on day 1, repeated every 3 weeks (1 cycle). The treatment was started within 45 days after surgery, and repeated for 4 cycles, followed by S-1 administration until 1 year after surgery. The primary endpoint was feasibility of the 4 cycles administration of S-1 plus docetaxel; secondary endpoints were safety, progression-free survival (PFS), OS, and feasibility of S-1 administration until 1 year after surgery. Results: We enrolled 53 pts, 42 males and 11 females with a median age of 65 years (range, 43-78), between May 2007 and August 2008. Pathological stages included IIIA in 36 pts and IIIB in 17 pts. The feasibility of planned 4 cycles of treatment was 77.4% (95% CI 63.8-87.7%, p < 0.001) with 41 pts out of 53 pts. Grade 4 neutropenia was observed in 28% of pts with grade 3 febrile neutropenia in 9%. Non-hematological toxicities of grade 3 or more involved fatigue in 6%, anorexia in 9%, and nausea in 6%. No treatment-related deaths occurred. Reasons for discontinuation were recurrent cancer in 1 pt, adverse events in 10, and miscellaneous in 1, respectively. 3 year overall survival was 78.8% (95% CI 68.4-90.7) and 3 year disease free survival was 50.3% (95% CI 34.4-73.3). Conclusions: Adjuvant S-1 plus docetaxel therapy is feasible and has only moderate toxicity in stage III gastric cancer pts. We believe that this regimen will be a candidate for future phase III trials seeking the optimal adjuvant chemotherapy for stage III gastric cancer patients.

Abstract Background: This study was conducted to assess the long-term outcomes of elderly patients among propensity-score-matched gastric cancer patients after curative gastrectomy and to propose the proper management of elderly gastric cancer patients.Methods: We enrolled 626 patients with gastric cancer who underwent curative gastrectomy at our institution between January 2004 and December 2015. To minimize selection bias among 2 groups, propensity score matching was performed.Results: Patients were divided into an elderly group over 75 years old (EP group; n=186) and a non-elderly group (NEP group; n=440). After propensity score matching, patients were divided into EP group (n=186) and NEP group (n=186). Five-year overall survival was significantly lower in the EP group than in the NEP group, consistent with a subgroup analysis of each stage. However, the 5-year disease-specific survival among all enrolled patients and those with stage I and II disease did not differ significantly. Moreover, in the subgroup of stage III patients, 5-year disease-specific survival was significantly lower in the EP group (23.0%) than in the NEP group (59.4%; P=0.004). Because elderly patients with stage III disease had an extremely poor prognosis, we decided to compare the two groups with stage III. The EP group contained significantly fewer patients with D2 lymphadectomy (P=0.002) and adjuvant chemotherapy (P<0.001) than the NEP group. Multivariate analysis revealed that older age and lymphatic invasion were independent prognostic factors. C-reactive protein to albumin ratio was significantly higher in patients in the EP group than in the NEP group (P=0.046), and the prognostic nutritional index was significantly lower in EP group patients than NEP group patients (P=0.045). Conclusions: Elderly gastric cancer patients with stage III disease showed poorer disease-specific survival compared with non-elderly patients, which may be due to fewer D2 lymphadenectomies, a lack of adjuvant chemotherapy, and a poorer nutritional and inflammatory background. The safe induction of standard lymphadenectomy and adjuvant chemotherapy with perioperative aggressive nutritional support may improve the prognosis of elderly gastric cancer patients with stage III disease.

TPS4142 Background: Complete surgical resections remains the only chance for cure in patients with gastric cancer, but approximately from 40% to 80% of patients still have recurrences and most patients ultimately die from their disease. The recent adjuvant trials in gastric cancer showed significantly improved survival in patients with adjuvant chemotherapy than those with surgery alone. However, further studies need for the effect of adjuvant chemotherapy following D2 dissected gastric cancer patients, especially in advanced gastric cancer. S-1 is an oral anticancer drug, a prodrug of fluorouracil, very effective in gastric cancer. Docetaxel is the first drug that showed survival benefits when added to the two drugs in advanced gastric cancer patients. And docetaxel is also synergistic anti-cancer effect with S-1 in advanced gastric cancer. Base on this background, the aim of this study is to detect a significant increase in 3 –year disease free survival (DFS) of adjuvant chemotherapy with docetaxel and S-1(DS) relative to those with S-1 and cisplatin (SP) in patients with stage III gastric cancer Methods: This study is an open-label, phase 3, randomized controlled trial, multicenter in South Korea. Patients with stage III (AJCC 7th edition) gastric cancer who had had curative D2 gastrectomy is randomly assigned to receive adjuvant chemotherapy of eight 3-week cycles of intravenous docetaxel (35 mg/m2 on day 1 and 8 of each cycle) plus oral S-1 (35 mg/m2 twice daily on days 1 to 14 of each cycle) for 6 months (DS) or chemotherapy of eight 3-week cycles of oral S1 plus intravenous cisplatin (60 mg/m2). After satisfying the screening criteria, patients have been randomized to the SD or SP arm in a 1:1 ratio. The randomization is stratified by institution and stage of disease (IIIA vs. IIIB vs. IIIC). The each stratum has been randomized by using the method of randomly permuted block. The primary endpoint is 3 year DFS, will analyze by intention to treat. A total of 290 patients will be enrolled, 67 patients have been treated to day, with continuing accrual. The trial is registered at ClinicalTrials.gov (NCT01283217).

Purpose: Various adjuvant chemotherapies have been introduced for gastric cancer patients after gastrectomy with D2 lymph node dissection. Although the mainstream regimen of adjuvant chemotherapy in Korea includes S-1 monotherapy (TS-1) and capecitabine with oxaliplatin (XELOX), few studies have compared the long-term efficacies of these 2 regimens. Methods: Between January 2010 and June 2017, 2021 patients were diagnosed with gastric cancer and underwent curative resection with adjuvant chemotherapy at our institution. Of 1461 patients with stage IB-III gastric cancer, 825 received TS-1 and 636 received XELOX as adjuvant chemotherapy. We retrospectively reviewed their medical records and analyzed the postoperative 5-year overall survival (OS) and disease-free survival (DFS) of these 2 groups. Results: The patients in the XELOX group had more advanced stage of cancer than the TS-1 group (stages III and II: 56.6% and 43.1%, respectively, in XELOX and 35.3% and 57.0% in TS-1; P < .001). The DFS did not differ significantly between the 2 study groups at any pathologic stage. The OS differed significantly only at pathologic stages IIA ( P  = .024) and IIB ( P  = .015). In a multivariate analysis of stage II patients, type of regimen was an independent prognostic factor of OS (XELOX vs TS-1; hazard ratio: 0.47, 95% confidence interval: 0.25-0.89, P  = .021). Conclusion: There were similar long-term efficacies between these 2 regimens in advanced gastric cancer patients who underwent curative surgery. However, the XELOX regimen might be favorable for OS of stage II patients.
