94 Background: Trastuzumab in combination with platinum-based chemotherapy is the standard first line regimen in HER2 positive advanced gastric cancer. However, there is no data concerning continuation of trastuzumab beyond first line progression. Methods: This retrospective multicenter study include all consecutive patients with HER2 + advanced gastric or gastro-esophageal junction (GEJ) adenocarcinoma who received after progression of trastuzumab plus platinum-based chemotherapy, a second line chemotherapy with irinotecan, taxane or platinum salt, with or without trastuzumab. The prognostic variables with P values ≤0.10 in univariate analysis were eligible for the Cox multivariable regression model. Results: From August 2007 to March 2015, 104 patients were included (median age, 60.8 years; male, 78.8%; PS 0-1, 71.2%) with advanced (metastatic : 99%) gastric (45.2%) or GEJ (54.8%) cancer. All patients had received first line treatment based on trastuzumab plus fluoropyrimidine and cisplatin (n=54; 51.9%) or oxaliplatin (n=50; 48.1%). As second line chemotherapy, 67 patients (64.4%) received FOLFIRI regimen, including 19 who have continued trastuzumab; 23 patients (22.1%) received a taxane regimen (paclitaxel or docetaxel), including 12 with trastuzumab; and 14 patients (13.5%) received a platinum-based chemotherapy (different from that used in first-line), including 8 with trastuzumab. When considering all regimens of second-line chemotherapy, continuation (n=39) versus discontinuation (n=65) of trastuzumab was significantly associated with an increase on PFS (4.4 vs 2.3 months; p=0.002) and OS (12.6 vs 6.1 months; p=0.001). In multivariate Cox model (including ECOG PS, tumor grade, number of metastatic site, and second-line treatment), continuation of trastuzumab was significantly associated with longer PFS (HR=0.56; 95%CI [0.35-0.89]; p=0.01) and OS (HR=0.47; 95%CI [0.28-0.79]; p=0.004). Conclusions: This study suggests that maintenance of trastuzumab plus second line chemotherapy beyond disease progression has clinical benefit in patients with HER2 positive advanced gastric cancer. These results deserve a prospective randomized validation.

Abstract Background Paclitaxel is used in second-line conventional chemotherapies to manage patients with unresectable advanced gastric cancer (GC). Paclitaxel-induced peripheral neuropathy is a known adverse event leading to treatment discontinuation. Additionally, oxaliplatin which causes irreversible peripheral neuropathy is now commonly used in first-line chemotherapy for advanced GC in Japan. Thus, examining the incidence of peripheral neuropathy with paclitaxel after oxaliplatin is necessary to improve the quality of life and outcomes of patients with advanced GC in the second-line treatment setting. Methods This prospective observational multicenter study, (which we named IVY study), will evaluate the degree of chemotherapy-induced peripheral neuropathy (CIPN) and the efficacy of second-line chemotherapy for unresectable advanced GC. A patient neurotoxicity questionnaire (PNQ) and the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) will be used to assess CIPN during the second-line treatment. The key eligibility criteria are as follows: 1) unresectable or recurrent GC histologically confirmed to be primary adenocarcinoma of the stomach, 2) age over 20 years, 3) Eastern Cooperative Oncology Group performance status score of 0–2, 4) written informed consent following full study information is provided to the patient, 5) progression or intolerance for first-line chemotherapy comprising fluorinated pyrimidine and platinum anticancer drugs (cisplatin or oxaliplatin) for advanced GC. 6) presence of evaluable lesions as confirmed using a computed tomography (CT) or magnetic resonance imaging. A total of 200 patients is considered to be appropriate for inclusion in this study. Discussion The results of this study will provide some information on CIPN with the sequential usage of oxaliplatin as first-line chemotherapy to paclitaxel as second-line chemotherapy in clinical practice. Trial registration This trial is registered in the University Hospital Medical Information Network’s Clinical Trials Registry with the registration number UMIN000033376 (Registered 11 July 2018).

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. No significant financial relationships to disclose.

e15540 Background: Second-line chemotherapy can now be considered as a proven treatment option for metastatic or locally advanced gastric cancer (AGC). Two global randomized phase III trials (REGARD and RAINBOW) showed that survival benefit was significantly observed in patients treated with ramucirumab (RAM) alone and in combination with weekly doses of PTX, compared with placebo, respectively. The purpose of the study is to evaluate the efficacy and safety of weekly dose of PTX combined with RAM practically as the second-line treatment in Japanese patients with AGC refractory to an S-1-containing chemotherapy regimen. Methods: We conducted a retrospective review of the data of 18 patients with AGC who received more than 2 cycles of PTX/RAM combined chemotherapy as the second-line regimen following S-1-based treatment. The objective response rate (ORR), adverse events, progression-free survival (PFS) and overall survival (OS) were analyzed and compared with PTX monotherapy group. Results: Median number of courses were 5 for the PTX/RAM group and the discontinuation of treatment except for disease progression was found in 2 cases (33.3%). The rates of hematological toxicities of higher than grade 3 were 33.3% in the PTX/RAM group, which were higher than those found in the PTX groups. The tumor responses of the PTX/RAM group were 22% for the ORR and 78% for the DCR, compared with 21% and 48% in the PTX group, respectively. The dose intensities of PTX were 72.4% in the former group. The survival data showed that the MST after second-line exposure was 290 days and the median PFS was 131 days in the PTX/RAM group, compared with 159 days and 90 days in the PTX group, which were not significantly different. Conclusions: PTX/RAM might be one of the best regimens for Japanese patients with AGC as the second-line treatment following S-1-containing chemotherapy.

105 Background: It remains uncertain whether every patient with advanced gastric cancer (AGC) who progresses after first-line chemotherapy should receive second-line chemotherapy. We conducted the present study to identify the optimal indications for second-line chemotherapy. Methods: In this retrospective study, 101 patients were included in univariate and multivariate analyses to identify clinicopathological variables independently associated with longer survival post progression (SPP), defined as the time from recognition of disease progression on first-line chemotherapy to death from any cause or last follow-up. Results: Median SPP of all patients was 340 days. On multivariate analysis, both performance status (PS) 2 (hazard ratio (HR), 14.234; 95% confidence interval (CI), 2.766–73.258), serum albumin (Alb) level < 3.5 g/dl (HR, 2.088; 95% CI, 1.047–4.060) at initiation of second-line chemotherapy, and time to progression (TTP) < 170 days on first-line chemotherapy (HR, 2.497; 95% CI, 1.227–5.083) were identified as independent prognostic factors for shorter SPP. Median SPP was 496, 375, and 232 days in patients with 0, 1, and 2 of these 3 negative prognostic factors, respectively (p = 0.0002). Conclusions: The present study suggests that second-line chemotherapy would be less beneficial in patients with 2 or more of the following 3 negative prognostic factors: PS 2, Alb < 3.5 g/dl at initiation of second-line chemotherapy, and TTP < 170 days on first-line chemotherapy.

132 Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse effect of platinum and paclitaxel (PTX) persisting for long time. In the Gastric Cancer Treatment Guideline (Japanese Gastric Cancer Association, 2018), first-line chemotherapy with fluoropyrimidine plus platinum followed by taxane based chemotherapy is recommended. It is not well known how much CIPN by platinum in the first-line chemotherapy affect the tolerability of second-line chemotherapy containing PTX (second-PTX). Methods: The subjects were advanced gastric cancer patients who received second-PTX after the platinum-containing first-line chemotherapy between March 2015 and June 2018. Patients were divided into two groups according to prior platinum: oxaliplatin (prior L-OHP) and cisplatin (prior CDDP) groups. CIPN was graded according to CTCAE ver.4. Severity of CIPN, dose reduction and discontinuation due to CIPN during the second-PTX were compared between the two groups. Results: 109 patients (50 prior L-OHP group and 59 prior CDDP group) were included in this retrospective study. The severity of CIPN just before second-PTX was 46% for grade 1 and 12% for grade 2 in the prior L-OHP group, and 8.5% and 0% in the prior CDDP group. The initial dose of PTX was reduced in 59 % of the prior L-OHP and in 39 % of the prior CDDP group. The worst grade of CIPN during second-PTX was 40% for grade 1, 34% for grade 2, 14% for grade 3 in the prior L-OHP group, and 33.9%, 20.3%, 0% in the prior CDDP group. Median time to grade 2 neuropathy during second-PTX was 2.5 months in the prior L-OHP group and 8.6 months in the prior CDDP group (p = 0.0004). CIPN-related dose reduction of PTX were 12.0% in the prior L-OHP group and 3.4% in the prior CDDP group (p = 0.177). Discontinuation of second-PTX due to CIPN were 10.0% in the prior L-OHP group and 5.1% in the prior CDDP group (p = 0.541). Conclusions: The severity of CIPN and tolerability of the second-PTX may be affected by prior platinum, L-OHP or CDDP, in the first-line chemotherapy for advanced gastric cancer.
