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.

64 Background: An altered expression of tumour angiogenesis-related factors has been constantly associated to a more aggressive phenotype and an increased relapse rate in several tumour types, including gastric cancer. Besides correlating with prognosis, tumour-driven angiogenesis seemed also able to influence response/resistance to chemotherapy in pre-clinical models. We examined the role of tumour angiogenesis genotyping in determining clinical outcome in metastatic gastric cancer patients receiving first-line chemotherapy. Methods: VEGF-A, VEGF-C, FLT1, KDR and FLT4 genotyping was performed on gastric tumours from 94 consecutive patients receiving platinum-based first-line chemotherapy. Results: Only theVEGF A rs25648 correlated with RR (PR = 18% among patients showing the VEGF A rs25648 CT or TT genotype vs. 44% among patients showing the VEGF A rs25648 CC genotype, p = 0.04). The VEGF A (rs2010963) and VEGF C (rs4604600 and rs7664413) correlated with mPFS and the VEGF A rs25648 and FLT4 rs307833 correlated with both mPFS and OS. Among other clinical variables tested (sex, age, ECOG performance status, gastrectomy, adjuvant chemotherapy, metastatic sites and second-line chemotherapy) only the use of second-line chemotherapy correlated with improved overall survival (10.2 months vs. 6.3 months for patients who received or did not receive second-line, p= 0.003). At multivariate the VEGF A rs25648 maintained an independent role in determining both median PFS (HR = 1.65 95% CI: 1.12-2.78, p= < 0.0001) and OS (HR = 1.58, 95% CI: 1.17-2.65, p = 0.0003). The use of second-line chemotherapy also showed an independent role in determining median OS (HR = 0.58, 95% CI: 0.38-0.87, p= 0.003). Conclusions: VEGF A rs25648 genotyping may help identifying a patients subgroup unlikely to benefit from a first-line, platinum-based combination and potentially candidate to alternative therapy choices. Our data may help designing future clinical trials with the aim to investigate the outcome of different chemotherapy regimens in different patients groups prospectively stratified according to angiogenesis profile.

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.

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.

15169 Background: Currently, there is no established second-line chemotherapy for pts with advanced gastric cancer who failed to respond or progressed after a first-line chemotherapy. Many of these pts still have a good performance status or have symptoms to be palliated at the time of first-line failure and are candidates for second-line chemotherapy. However, phase II trials demonstrate divergent results about pts more likely to benefit from second-line chemotherapy. We retrospectively analyzed the influence of various clinicopathologic factors on the survival of pts treated with second-line chemotherapy. Methods: Analysis is based on the data of 169 pts consecutively treated at 3 oncology department with a second-line chemotherapy. Univariate and multivariate analyses were performed to determine prognostic factors of survival. The variable used for analysis were: sex, age, ECOG performance status, a weight loss > 5 Kg in the last month; site of primary tumor, histopathology; hemoglobin, serum albumin, and CEA levels, number and site of metastatic disease, response to and time-to-progression (TTP) with the first- line chemotherapy. Results: The variables predictive of better survival were: ECOG PS 0–1 (p<0.001), no weight loss (p=0.001), hemoglobin level > 10 g/dl (p=0.01), CEA level <50 U/ml (p<0.02), number of metastatic sites = 2 (p=0.002), TTP of the first-line chemotherapy > 4 months (p=0.008). Peritoneal carcinomatosis was predictive of poor survival only when associated with one or more signs or symptoms as vomiting, anorexia, abdominal pain, ascites(p=0.03). Four factors were independently associated with better overall survival: ECOG PS 0–1 (p=0.002; HR 0.46; CI 95%, 0.29–0.75), CEA level <50 U/ml (p=0.008; HR 0.54; CI 95%, 0.35–0.85), one or two metastatic sites of disease (p=0.01; HR 0.58; CI 95%, 0.39–0.88), and TTP of the first-line chemotherapy > 4 months (p=0.02; HR 0.66; CI 95%, 0.45–0.95). Conclusions: In the absence of data deriving from randomized, controlled, clinical trials, this analysis suggests that some clinical factors may help clinicians to better select groups of pts with gastric cancer more likely to benefit from a second-line chemotherapy. No significant financial relationships to disclose.

4515 Background: PSA kinetics, and more specifically a 30% decline in PSA following initiation of first-line chemotherapy with docetaxel, has been reported to be a surrogate endpoint for OS in mCRPC pts. The objective of this analysis was to evaluate PSA kinetics as surrogate endpoints for overall survival (OS) in patients who were receiving second line chemotherapy following progression after docetaxel front line therapy. Methods: Data from a phase III trial of 755 mCRPC pts randomized to treatment with cabazitaxel in combination with prednisone (C+P) every 3 weeks or mitoxantrone in combination with prednisone (M+P) were used. All pts were previously treated with a docetaxel-containing regimen. PSA decline (≥30% and ≥50% ) and PSA velocity within the first three months of treatment were evaluated as potential surrogate endpoints for OS. The proportional hazards (PH) model was used to test for Prentice’s criteria and the proportion of treatment explained (PTE) was computed as a second test of surrogacy. PTE was defined as one minus the ratio of the treatment coefficient in the adjusted PH model (includes PSA decline or velocity) to the treatment coefficient in the unadjusted PH model. Results: Of 755 men, 654 had sufficient PSA data to be included in the analysis. Treatment arm (C+P vs. M+P) was prognostic of OS with a hazard ratio (HR) of 0.65 (95% CI=0.54-0.79, p<0.001). A 30% PSA decline within three months of treatment was associated with a HR of 0.46 (95% CI 0.37-0.57, p-value<0.001) for OS. After adjusting for treatment effect, the HR for 30% PSA decline was 0.50 (95% CI= 0.40-0.62, p<0.001) but treatment arm remained statistically significant thus failing Prentice’s third criterion. The PTE for ≥30% decline in PSA within three months was 0.39 (95% CI= 0.36-0.42) indicating a lack of surrogacy for OS. Similar results were observed for pts who experienced ≥50% decline in PSA and PSA velocity. Conclusions: Neither PSA decline (≥30% and ≥50%) nor PSA velocity within the first three months of therapy are surrogate endpoints for OS in pts receiving second line chemotherapy.
