103 Background: Palliative chemotherapy is the mainstay for the treatment of advanced gastric cancer (AGC) patients with peritoneal metastasis. In general, chemotherapy regimen is changed when patients show disease progression on CT scan. However, nearly 40% of these patients have no measurable lesions. It remains uncertain how clinicians can decide the timing of treatment change for AGC patients with non-measurable peritoneal metastasis alone. Methods: There were 217 patients with primary unresectable or recurrent gastric cancer at our institution between April, 2005 and March, 2012. Among them, 50 patients, who had histologically proven non-measurable peritoneal metastasis alone, were retrospectively identified and investigated in this study. They underwent measurements of tumor markers (TM) every month and abdominal CT scan every 2 months. For these 50 patients, chemotherapy regimen was changed based on the following different 2 criteria; 1. elevated TM and/or aggravated clinical symptoms alone (n=21), 2. radiologically confirmed disease progression (n=29). We assessed whether these two different criteria have any impact on overall survival (OS) by univariate and multivariate analyses. Results: Median survival time of all 50 patients was 604 days. Multivariate analysis identified pre-treatment performance status of 0-1 (hazard ratio (HR) 0.211, 95% confidence interval (CI) 0.045–0.998, P=0.049), initial hemoglobin level of 10 mg/dl or more (HR 0.114, 95% CI 0.014–0.936, P=0.043) and the TM / symptom based treatment change (HR 0.124, 95% CI 0.043–0.360, P=0.001) as significant prognostic factors for favorable OS. Conclusions: Early decision making of treatment change based on elevated TM and/or aggravated clinical symptoms alone might contribute to longer OS in AGC patients with non-measurable peritoneal metastasis alone.

Peritoneal metastasis (PM) is detected in 14% of gastric cancers at the time of initial diagnosis, with a median survival time of 4 months. A 66-year-old woman diagnosed with cT4a(SE) N2M1(LYN) cStage IV was treated with three lines of chemotherapy for a year. During the third line of chemotherapy, computed tomography (CT) scan revealed a large amount of ascites, periportal collar sign, and bilateral ureteral stenosis owing to PM. The tumor biomarkers (CEA and CA 19–9) remained elevated similar to the initial levels. The patient was administered 3 mg/kg nivolumab intravenously biweekly as the fourth line of chemotherapy. Three months after the nivolumab treatment, gastroscopy revealed an extreme reduction of the tumor size, while CT scan revealed the absence of ascites and a well-controlled tumor. There was no immune-related adverse event with nivolumab during and after the treatment, and performance status improved to 0. The patient has been alive for about 2.5 years since her first visit with her sixth line of chemotherapy (docetaxel). We report a case of advanced gastric cancer with PM that was treated successfully with nivolumab.

133 Background: We performed multicenter retrospective study to evaluate the activity and the safety of a docetaxel as the third-line chemotherapy in advanced gastric cancer (AGC) patients who had undergone oxaliplatin (FOLFOX) and irinotecan (FOLFIRI)-based chemotherapy regimens. Methods: Thirty-eight patients with AGC previously treated were eligible for this study. Patients received docetaxel 30 mg/m2 +/- cisplatin 30 mg/m2 IV on day 1, 8 or docetaxel 60 mg/m2 +/- cisplatin 60 mg/m2 IV on day 1 every 3 weeks until disease progression, and responses were assessed after every two cycles according to RECIST criteria and toxicity was evaluated by NCI-CTC. Results: Thirty-two out of 38 patients were evaluable for response. A total of 95.1 cycles of chemotherapy (median 2, range 0.5–7) were administered. Relative dose intensities of docetaxel and cisplatin were 93.4% and 87.8%, respectively. The overall response rate was 15.6% and the disease control rate was 50%. With a median follow-up duration of 3.1 months (range 0.3-14.3 months), 36 patients had disease progression, and 34 patients had died at the time of analysis. The median progression-free survival was 1.8 months (95% CI, 1.3–2.3 months). The median overall survival was 3.1 months (95% CI, 2.3–3.9 months). Grade 3 or 4 hematologic toxicities included neutropenia in thirteen patients (38.3%), febrile neutropenia in four patients (11.7%). and thrombocytopenia in one patient (2.9%). Other grade 3 or 4 toxicities included neuropathy in three patients (8.8%) and mucositis in two patients (5.9%). There were three treatment-related deaths (8.8%) caused by infection associated with neutropenia. Conclusions: Salvage docetaxel chemotherapy in AGC patients failed in oxaliplatin and irinotecan-based treatment is not recommend routinely. However, selected patients with good performance status and sufficient albumin levels may have derived some survival benefits from salvage chemotherapy. No significant financial relationships to disclose.

185 Background: Ramucirumab (RAM) is a novel anti-VEGF antibody approved in 2015 in Japan. Predictive factors for RAM in combination with paclitaxel (PTX) remain largely unknown. Methods: We reviewed 77 consecutive advanced gastric cancer patients who were treated with RAM plus PTX between June 2015 and June 2016 in our institution. We evaluated treatment outcome and analyzed potential predictive factors by univariate and multivariate analyses. Results: Median age was 67 years (range 35-83) and 51 % of the patients were male. The ECOG performance status (PS) was ≥ 2 in 8 patients. 89% (69/77) patients were treated as second line chemotherapy. Objective response rate (ORR) in patients who have measurable disease was 52 % (17/33). Median progression free survival (PFS) and overall survival (OS) and was 6.0 months (95% confidence interval [CI] = 4.3-7.1) and 10.4 months (95% CI 6.8-13.6), respectively. The most frequent adverse events were peripheral neuropathy (44%), G3 ≥ neutropenia (34%), hypertension (32%) and bleeding (27%). At multivariate analysis, hypertension was independent factor for OS (Hazard ratio [HR] = 0.35, 95% CI = 0.14-0.90, P = 0.03). Also, bleeding (HR = 0.23, 95% CI = 0.09-0.55, P = 0.001) was independent factor for PFS and hypertension (HR = 0.47, 95% CI = 0.22-1.02, P = 0.06) had trend toward to show better PFS. Conclusions: RAM plus PTX showed promising efficacy for advanced gastric cancer. RAM related toxicities such as hypertension and bleeding/hemorrhage were independent factors for better outcome. Further investigation is warranted to verify our analysis.

4092 Background: A large number of advanced gastric cancer patients undergoing curative gastrectomy with D2 lymph node dissection (D2 gastrectomy) show peritoneal metastasis. The source of these metastatic cells and their treatment remain unclear. We examined the mechanism of surgery-induced peritoneal metastasis and determined the appropriate intraoperative treatment. Methods: (1) Curative gastrectomy was performed for 102 gastric cancer patients. Peritoneal lavage fluid was collected before and after gastrectomy. Cytology, RT-PCR, and cell culture were used to determine the presence of cancer cells. Proliferative potential of tumor cells was evaluated using Ki-67 staining. Tumorigenic capacity was assessed by cell injection into the peritoneal cavity of NOD/ShiJic-scid mice. (2) Fifty clinical T3(SE) or T4(SI) advanced gastric cancer patients undergoing curative D2 gastrectomy prospectively received intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) in a phase II trial. HIPEC comprised 50 mg CDDP, 10 mg MMC, and 1000 mg 5-FU in 5 L saline maintained at 42–43C° for 30 min. Results: (1) Of 102 peritoneal lavage fluid samples obtained before gastrectomy, 57 from both early and advanced cancer patients did not contain CEA or CK20 mRNA amplification products or cancer cells. Of these 57 samples, CEA or CK20 mRNA was detected in 35 and viable cancer cells were identified in 24 after gastrectomy. Viable cancer cells in all 24 cases showed Ki-67 positivity, indicating proliferative activity. Cultured viable cancer cells developed into peritoneal tumor nodules after spill over into the peritoneal cavity in NOD/ShiJic-scid mice. (2) Fifty patients were eligible for the phase II clinical trial. The overall 5-year survival rate for all patients was 92.4%. This rate in patients with pT2(ss) (n = 12), pT3(se) (n = 35), and pT4(si) (n = 3) disease was 90.0%, 92.3%, and 100%, respectively. Only 2 patients (4%) showed peritoneal relapse. Conclusions: Viable tumorigenic cancer cells spilled over the peritoneal cavity during curative gastrectomy. Intraoperative HIPEC following curative D2 gastrectomy effectively prevented peritoneal metastasis, thereby potentially improving the prognosis of patients with advanced gastric cancer.
