207 Background: Gastric cancer is the second causes of cancer-related deaths in the world and its incidence of advanced gastric cancer (AGC) in the elderly is increasing as a result of increased life expectancy. However, elderly patients have been underrepresented in many kinds of chemotherapy clinical trials. Therefore it is difficult to evaluate the efficacy and safety of chemotherapy for elderly patients and select the appropriate patients aged 70 years or older who are likely to benefit from the chemotherapy. Methods: There were 265 patients with primary unresectable or recurrent gastric cancer treated at our institution between April 2007 and March 2014. Of all, 90 patients aged 70 years or older were retrospectively identified. We evaluated the efficacy of the chemotherapy and prognostic significance of clinico-pathologic factors to identify the optimal indications for chemotherapy. Univariate and multivariate analyses were perfomed on the base-line characteristics such as patient’s performance status (PS), gender, chemotherapy regimens, history of gastrectomy, presense of co-morbidity, serum LDH level, serum C reactive protein, and nutritional status, at the initiation of the first-line chemotherapy. Results: The median overall survival time (OS) was 343 days and the median TTF on first-line chemotherapy was 111 days. The toxicity was mild and tolerable. There were no significant difference in overall survival between patients receiving monotherapy and combination therapy. On multivariate analyses, PS 1 or 2 (hazard ratio (HR), 1.883; 95% confidence interval (CI), 1.047–3.390), presence of primary tumor (HR, 1.916; 95% CI, 1.063–3.448) at the initiation of the first- line chemotherapy were identified as significant independent poor prognostic factors for overall survival. Especially in patients aged 75 years or older, only PS was an independent prognostic factor for OS (HR, 3.703; 95% CI, 1.314–9.900). Conclusions: Analysis of our results shows that patients aged 70 years or older with good performance status and absence of primary tumor might achieve clinical benefit from chemotherapy.

15113 Background: First-line chemotherapy for advanced/recurrent gastric cancer has limited efficacy, achieving a median survival time (MST) of about 7 months, while addition of second-line and subsequent chemotherapy may prolong MST to about 11.5 months. In practice, however, about half of patients failing with first-line chemotherapy are unable to receive second-line chemotherapy because of worsening of their performance status (PS), disease progression, or toxicities during protracted first-line chemotherapy. We studied the feasibility of a sequential fixed regimen devised to ensure prompt initiation of second-line chemotherapy after first-line failure. Methods: Between December 2002 and December 2006, patients with advanced or recurrent gastric cancer were enrolled who met the following requirements: 1) major organ function preserved; 2) PS 0–2; 3) presence of at least one evaluable lesion; and 4) written informed consent. The treatment regimen consisted of 3 courses of single-agent S-1 or S-1/cisplatin combination followed by weekly paclitaxel (wPTX). The endpoints of the study were entry to the second-line treatment, time to failure (TTF), and MST. Results: Of 39 patients enrolled, 37 completed first- line S-1. Twenty-eight patients (76%) then received wPTX, 2 non-wPTX chemotherapy, and 6 surgery; only 1 received no additional treatments. Second-line wPTX was followed by a third-line treatment in 23/28 patients (82%). The TTF with the sequential fixed regimen was 7 months. The MST and the 1- and 2-year survival rates in the 37 completing first-line treatment were 14.6 months, 61% and 25%, while those in the 28 switched over to wPTX were 12.5 months, 51% and 17%. Conclusions: Patients with advanced/recurrent gastric cancer treated sequentially with a fixed number of courses of S-1 followed by wPTX may have a good chance of treatment continuation. A sequential fixed regimen may further improve survival of patients with advanced/recurrent gastric cancer only with combinations of currently available drugs.

e15173 Background: S-1 monotherapy or S-1/CDDP have remained important as a standard chemotherapy regimen for patients with advanced gastric cancer (AGC), based on the randomized phase III trials. Although S-1/docetaxel has been reported highly active and well tolerated for AGC by many researchers, it could not show the superiority compared with S-1 monotherapy in the recent international randomized trial. We have also demonstrated that it might be effective for patients with Stage III AGC in both preoperative and postoperative adjuvant setting. The aim of this study was to evaluate efficacy, toxicity and validity of S-1/docetaxel retrospectively, compared with the standard regimens. Methods: We conducted a retrospective review of the data of 89 patients with AGC who received chemotherapy who were given S-1-containing regimens as the first line chemotherapy; 15 patients treated with S-1 monotherapy, 21 with S-1/CDDP, and 53 with S-1/docetaxel. The objective response, adverse event (AE), progression-free survival (PFS), and overall survival (OS) were compared between the three groups. Results: The overall response rates (ORRs) were obtained 6.7%, 38.1% and 30.2% for S-1 monotherapy, S-1/CDDP, and S-1/docetaxel, respectively. The incidence of AEs was more frequent in S-1 based combined treatments than in the S-1 monotherapy, however there was no significant difference in the severe AEs between each group. Survival data showed that the PFSs were 121 days, 199 days and 178 days, respectively, and there was the significant difference between S-1 monotherapy and S-1/docetaxel (p<0.05). The overall survival showed that the MSTs were not significantly different. The conversion rate to the subsequent treatments following S-1 monotherapy was higher than the other treatments. Conclusions: S-1/docetaxel was active and well tolerated for the patients with ARGC as the first line. Although the Japanese guideline for treatment of gastric cancer recommends S-1 monotherapy or S-1/CDDP as the standard regimens, docetaxel could be applied for patients with AGC in case of CDDP-resistant or –naïve patients.

e15544 Background: Although combination chemotherapy as ECF (epirubicin, cisplatin, and 5-FU) and DCF (docetaxel, cisplatin, and 5-FU) are effective advanced gastric cancer, but it is too toxic to apply for elderly patients with increased comorbidity. Combination of oxaliplatin and 5-FU has proven to be a effective and tolerable regimen in advanced gastric cancer, and we investigated the efficacy and safety of reduced-dose combination chemotherapy of oxaliplatin/5-FU/folic acid as first-line chemotherapy in elderly patients with metastatic or recurrent gastric cancer. Methods: Elderly patients (≥60 years) with measurable, metastatic or recurrent gastric cancer were enrolled. Patients received oxaliplatin 75mg/m2 (2-hour intravenous infusion on D1), 5-FU 1000mg/m2 (12-hour continuous infusion on D1,2), and folic acid 20mg/m2 (15-minute infusion on D1,2) every 2 weeks. Results: Total 37 patients were enrolled between April 2004 and August 2008. Median age was 67 years old (range, 60 to 80 years), and 22 patients (59.5%) had increased Charlson comorbidity index score (CCI ≥1). Of 36 evaluable patients, 2 patients achieved complete response (CR), and 12 patients partial response (PR) with representing overall response rate of 44.4% (95% CI 27.7- 60.2). Stable disease (SD) was observed in 12 patients (33.3%), and progressive disease in 8 patients (22.3%). The median time to progression was 4.6 months, and median overall survival was 9.2 months. Relative dose intensity was 97.4% in both oxaliplatin and 5-FU. Grade 3 or 4 hematologic toxicities included neutropenia in one patients (2.7%), and anemia in three patients (8.1%). Peripheral neuropathy occurred (grade 2) was only observed in three patients (8.1%). Conclusions: The reduced-dose combination chemotherapy of oxaliplatin/5-FU/folic acid was effective and tolerable in elderly patients with metastatic or recurrent gastric cancer as first-line treatment.

15035 Background: Paclitaxel has been shown to be effective in patients with advanced gastric cancer. We assess the combination of paclitaxel (Anzatax®, Mayne Pharma), infusional 5-fluorouracil and Cisplatin as first-line chemotherapy for metastatic or recurrent gastric cancer. Methods: Patients with previously untreated metastatic gastric adenocarcinomas are eligible. Fifty patients received paclitaxel (Anzatax®, Mayne Pharma) 150mg/m2 by 2-hour infusion day 1, cisplatin 15 mg/m2 daily days 1 through 5, and 5- fluorouracil by continuous infusion at a dose of 600 mg//m2 daily days 1 through 5. Cycles were repeated every 3weeks until progression. Objective tumor responses, duration of response, time to progression, and toxicity profile are the end points evaluated in this study. Results: Total 50 patients were enrolled (41 men, 9 women). The median age was 59 years (range 32 - 75). All patients had ECOG performance status (PS) 0–2 and adequate organ functions. 50 patients completed one-six cycles (mean 3 cycles). Forty-four patients were evaluable and all patients were assessable toxicity. In these 44 assessable patients, 1 CRs and 14 PRs were obtained, resulting in an overall response rate of 34%. 19 patients (43.2%) had stable disease, and 3 patients (8.9%) progressed. The tumor control rate was 77.3%. The median time to progression(TTP) was 5 months. The major (Grade 3–4) toxicities were neutropenia (22%) and anorexia (4%). There were no treatment-related deaths were recorded in all patients. The median and overall survival times are now being followed up and the results will be announced during the ASCO 2007 annual meeting. Conclusion: The combination of paclitaxel (Anzatax®, Mayne Pharma), cisplatin,and 5-FU has substantial antitumor activity in advanced gastric cancer. The toxicity of this regimen is within acceptable range, but no remarkable response rate was noted. Paclitaxel is an important new agent in the treatment of gastric cancer, and further evaluation of this agent in combination chemotherapy is warranted.
