154 Background: While taxane-monotherapy following fluoropyrimidine plus platinum is recognized as the standard treatment strategy for advanced gastric cancer, triplet chemotherapy with docetaxel, cisplatin and S-1 (DCS) is another option for first-line therapy in Japan. However, efficacy of taxane after DCS therapy has not been sufficiently evaluated. Methods: We retrospectively evaluated the efficacy and safety of taxane-monotherapy after DCS between January 2010 and April 2015 for advanced gastric cancer. The taxane-monotherapy included weekly paclitaxel (PTX) (80 mg/m2, day 1, 8 and 15 of a 28-day cycle) and triweekly nab-PTX (260 mg/m2, day 1). Other selection criteria were: ECOG PS < 2; adequate organ function; no severe ascites; HER2-negative. Results: Thirty of 92 patients who had been treated with DCS received taxane-monotherapy. Fifteen and 15 patients received taxane-monotherapy as the second and third-line treatment, respectively. Patients characteristics of each group (2nd/3rd) were; median age: 64/62 (range 27-75/42-75); ECOG PS ≤ 1: 14/13; number of metastatic sites ≥ 2: 9/12; median taxane-free interval from first-line treatment: 1.6/3.4 (range 0.9-2.3/2.2-8.3) months; median total dose of prior DTX: 349/208 (range 39-844/141-685) mg/m2. Number of patients who received PTX/nab-PTX were 10/5 and 13/2 in the second and third line treatment. Median relative dose intensity of taxane was 96.4% (range 57.6-172.9%) in the second-line, 98.5% (44.0-166.8%) in the third-line group. Response rate and disease control rate were 0% and 37.5% in the second-line, and 0% and 38.5% in the third-line group. Median progression free survival and overall survival were 3.4 and 5.8 months in the second-line group, and 2.0 and 4.5 months in the third-line. Grade 3 or 4 neutropenia, anemia, and anorexia, occurred in 33%, 13% and 13% in the second-line group, and 6.7%, 13% and 6.7% in the third–line group, associated with no treatment related death. Conclusions: It is suggested that taxane-monotherapy has acceptable toxicities but insufficient efficacy in advanced gastric cancer patients after DCS therapy.

AbstractBackground & AimsThe efficacy and safety of lenvatinib (LEN) as a second/third-line treatment for unresectable hepatocellular carcinoma (HCC) after sorafenib (SOR) therapy remains unknown. We evaluated the outcomes of second/third-line treatment of LEN, investigated the sensitivity of SOR-resistant HCC cell line (PLC/PRF5-R2) to LEN, and their signal transduction pathway by protein array analysis.MethodsWe retrospectively enrolled 57 unresectable HCC patients. Radiologic responses in 53 patients were evaluated by modified Response Evaluation Criteria in Solid Tumors. Active signal transduction pathways in cells were identified by protein array analysis, including 1205 proteins.ResultsPatients comprised 34 tyrosine kinase inhibitor (TKI)-naive (first-line), nine SOR-intolerant (second-line), and ten resistant to regorafenib (third-line). Objective response rates (ORRs) were 61.8% (21/34) in TKI-naive, 33.3% (3/9) in second-line, and 20.0% (2/10) in third-line groups. The overall survival (OS) and the progression free survival (PFS) in the first-line was significantly longer than those in third-line group (p<0.05). Patients with better liver functional reserve (Child score, ALBI grade) exhibited higher ORR and longer OS. LEN was well-tolerated as second/third-line treatment. The IC50 value of LEN against PLC/PRF5-R2 cells (30 μM) was significantly higher than that against PLC/PRF5 cells (6.4 μM). LEN inhibited significantly more signal transduction pathways related to FRS2, a crucial FGFR downstream molecule, in PLC/PRF5 than PLC/PRF5-R2 cells.ConclusionsLEN was active and safe as a second/third-line treatment for unresectable HCC. LEN seems to be more effective for HCC patients with better hepatic reserve function or before TKI-resistance is acquired because of partial cross-resistance to SOR.

83 Background: As a result of ATTRACTION2, nivolumab was added to the third line treatment in advanced gastric cancer (AGC), but the response rate was about 10%. As there is no predictive biomarker and no comparison with cytotoxic regimen, it is difficult to choice the regimen. Therefore, we examined the treatment outcome of cytotoxic regimen in third line treatment in the real world retrospectively. Methods: We retrospectively evaluated efficacy and safety of cytotoxic regimen as third-line treatment in patients with AGC between July 2015 and December 2017. Results: Among 138 patients received chemotherapy as first line, 29 patients (21%) received third line therapy. The characteristics were as follows; the median age, 70 years old (range 34-80); male/female, 19 (66%)/10 (34%); performance status (PS) 0/1/2, 7/18/4. The overall response rate was 19% and the disease control rate was 38%. The median overall survival (OS) was 6.6 months and the progression free survival was 3.8 months. The most common grade 3/4 hematological toxicities were neutropenia (27%), followed by anemia (27%) and febrile neutropenia (13.7%). Grade 3/4 nonhematological toxicities included anorexia (27.6%), diarrhea (10%), nausea (10%). Conclusions: Cytotoxic regimen as third line showed acceptable activity, but only 21% of patients could received the third line chemotherapy. The further investigation of predictive biomarker of nivolumab is expected.

Background: The use of nivolumab or irinotecan as the third-line treatment for patients with advanced gastric cancer (AGC) remains controversial. Methods: This study analyzed patients with AGC treated with nivolumab or irinotecan (nivolumab group or irinotecan group, respectively) from May 2016 to April 2019 following two or more previous lines of chemotherapy. Univariate survival analysis was conducted to identify the clinical and molecular factors associated with progression-free survival (PFS). Results: A total of 156 patients (74 treated with nivolumab and 82 treated with irinotecan) were analyzed. The median PFS was 1.9 months in both treatment groups. The median overall survival (OS) was 7.2 and 6.2 months in the nivolumab and irinotecan groups, respectively. Eastern Cooperative Oncology Group performance status of 1 or more, liver metastasis, a large tumor size at baseline, and HER2-positive status were associated with a worse PFS in the nivolumab group compared with the irinotecan group. The nivolumab group showed a significantly longer PFS (median 3.1 versus 2.0 months) and OS (median 12.9 versus 7.8 months) than the irinotecan group in patients with 0 or 1 of these factors, whereas the irinotecan group showed a significantly longer PFS (median 1.0 versus 1.8 months) and a trend of longer OS (median 3.9 versus 6.1 months) in patients with ⩾2 of these factors. Conclusions: Some clinical and molecular factors were associated with outcomes following nivolumab or irinotecan as the third- or later-line treatment in patients with AGC. These factors must be considered while selecting an optimal treatment option.

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.
