Background: The heterogeneity of gastric cancer makes the identification of potential prognostic indicators particularly important. The Ki67 and BCL2 proteins are known prognostic markers for different types of cancer. Ki67 is associated with cell proliferation, whereas BCL2 has antiproliferative roles. A combined marker based on these opposite functions might provide improved prognostic information in gastric cancer. Method: Ki67 and BCL2 expression was assessed in 276 gastric adenocarcinoma tissue microarrays. A Ki67/BCL2 index based on the relative expression of each protein was divided into low- and high-risk groups using receiver operating characteristic curves. Results: A high Ki67/BCL2 index significantly correlated with advanced stage, recurrence, intestinal type, high histologic grade, and lymphatic and perineural invasion (all p < 0.05). Univariate and multivariate analyses revealed a significant relationship between disease-free or overall survival and the Ki67/BCL2 index in intestinal-type gastric cancer (all p < 0.05). Conclusions: A combined marker using Ki67 and BCL2 could be a useful indicator for predicting survival in patients with intestinal-type gastric cancer.

61 Background: Considering the heterogeneity of gastric cancer, it is particularly important to identify potential prognostic indicators. Ki67 and B-cell lymphoma 2 (BCL2) proteins are known prognostic markers in different types of cancer. Ki67 is associated with cell proliferation, whereas BCL2 has anti-proliferative roles. A combined marker based on these opposite functions might provide improved prognostic information in gastric cancer. The aim of this study is to investigate correlations between a combined marker using Ki67 and BCL2 and clinicopathologic parameters, and to evaluate the prognostic value of the combinatorial marker in patients with different types of gastric cancer. Methods: This study assessed Ki67 and BCL2 expression using tissue microarray obtained from 276 patients with adenocarcinoma of the stomach. A Ki67/BCL2 index based on the relative expression of each protein was divided into low- and high-risk groups using receiver operating characteristic (ROC) curves. Results: High Ki67/BCL2 index was significantly associated with advanced AJCC stage, high recurrence, diffuse or mixed type, high histological grade, and the presence of lymphatic and perineural invasion (all p < 0.05). Univariate and multivariate analyses revealed a significant relationship between disease-free or overall survival and Ki67/BCL2 index in intestinal-type gastric cancer(all p < 0.05). Conclusions: A combined marker using Ki67 and BCL2 could be a useful indicator for predicting survival in patients with intestinal-type gastric cancer.

PURPOSE: The efficacy of adjuvant chemotherapy in gastric cancer is controversial. We conducted a phase III, randomized, multicentric clinical trial with the goal of assessing the efficacy of the combination of mitomycin plus tegafur in prolonging the disease-free survival and overall survival of patients with resected stage III gastric cancer. PATIENTS AND METHODS: Patients with resected stage III gastric adenocarcinoma were randomly assigned, using sealed envelopes, to receive either chemotherapy or no further treatment. Chemotherapy was started within 28 days after surgery according to the following schedule: mitomycin 20 mg/m2 intravenously (bolus) at day 1 of chemotherapy; 30 days later, oral tegafur at 400 mg bid daily for 3 months. Disease-free survival and overall survival were estimated using the Kaplan-Meier analysis and the Cox proportional hazards model. RESULTS: Between January 1988 and September 1994, 148 patients from 10 hospitals in Catalonia, Spain, were included in the study. The median follow-up period was 37 months. The tolerability of the treatment was excellent. The overall survival and disease-free survival were higher in the group of patients treated with chemotherapy (P = .04 for survival and P = .01 for disease-free survival in the log-rank test). The overall 5-year survival rate and the 5-year disease-free survival rate were, respectively, 56% and 51% in the treatment group and 36% and 31% in the control group. CONCLUSION: Our positive results are consistent with the results of recent studies; which conclude that there is a potential benefit from adjuvant chemotherapy in resected gastric cancer.

PURPOSE: To study the invasion-related molecule urokinase-type plasminogen activator receptor (u-PAR) expressed by disseminated tumor cells as a biologic predictor of poor survival in a large prospective series of patients with gastric cancer. PATIENTS AND METHODS: In 156 gastric cancer patients (prospective series), disseminated tumor cells in the bone marrow and the u-PAR expressed by these tumor cells were determined by cytokeratin (CK) 18 immunocytochemistry and u-PAR/CK18 double immunocytochemistry. RESULTS: In contrast to the mere detection of disseminated tumor cells at primary surgery, the additional evidence of u-PAR on these cells correlated significantly with pathologic T stage (P = .0474) and the expression of u-PAR (P = .0093) and plasminogen-activator inhibitor 1 (P = .0145) in the primary tumor (immunohistochemistry, χ2). Kaplan-Meier analysis revealed no association with prognosis for the mere detection of disseminated tumor cells. In contrast, a significant association was seen between detection of u-PAR on these cells and shorter disease-free (P < .0001) and overall survival (P < .0001). Multivariate analysis revealed that u-PAR on disseminated tumor cells at the time of primary surgery is an independent prognostic factor for disease-free (95% confidence interval [CI], 1.72 to 3.21; P = .024) and overall survival (P = .0049; relative risk, 2.89; 95% CI, 1.92 to 4.30). CONCLUSION: This is the first large study to show that u-PAR, detected on disseminated tumor cells in the bone marrow, is an independent prognostic parameter in gastric cancer, in contrast to the mere detection of minimal residual disease (MRD). u-PAR may be a promising marker to define a critical subpopulation of disseminated tumor cells and a target to eliminate MRD. Molecular phenotyping of MRD is critical for defining its individual clinical relevance.

e14670 Background: HER-2 and Topo-2A genes are settled on a chromosome 17 and their co-amplification rates are high. In this study, early gastric cancer patients who received adjuvant chemo-radiotherapy and chemotherapy were evaluated with HER-2 and Topo-2A expression in association with clinical and histopathologic findings. Methods: A total of 103 gastric cancer patients were included the study. The HER-2 and Topo-2A levels were measured by immunohistochemistry in postoperative tumor materials. A standard evaluation method was admitted for HER-2 positivity, while Topo-2A nuclear staining 3+ and 4+ were considered as overexpression. Those with level 2+ or 3+ of HER-2, the FISH test were attempted. Results: The median follow-up was 19 months (ranges 2–70 months). Forty-six patients (44%) relapsed during follow-up whereas 60 patients (58%) had died. The median overall survival (mOS) was 23 months. Histopathologies of HER-2 positive patients were intestinal type in 7 (87.5%) and diffuse type in one (12.5%) patient. In the follow-up period 4 patients (50%) were died (mOS was 17 months in this group). Median overall survival was 23 months in HER-2 negative group (p=0.6). Histopathologies of Topo-2A positive patients were intestinal type in 9 (64.2%) and diffuse type in 5 (35.8%) patient. In the follow-up period 8 patients (57%) were died (mOS was 22 months in this group). Median overall survival was 23 months in Topo-2A negative group (p=0.8). Three patients (37.5%) who had HER-2 positive histopathologies also had Topo-2A positivity. Conclusions: Overexpression rates of HER-2 in gastric cancer were reported 6.8-34%. Racial differences and different scoring techniques thought to be impact the results. Co-amplification rate of HER-2 and Topo-2A was reported 34% in gastric cancer. In our study HER-2 and Topo-2A overexpression rates were 7.7% and 13.6% respectively and co-amplification of HER-2 with Topo-2A rate was 37.5% is also similar to the other studies. Stages of patients with HER-2 and Topo-2A overexpression were similar to the distribution of the overall patients. While intestinal subtypes showed a higher rate of HER-2 overexpression, the median survival times tend to be shorter in HER-2 positive patients.

117 Background: Autologous, tumor-derived heat shock protein Gp96 peptides complexes have shown antitumor potential in various cancers. We conducted the first Phase II trial to evaluate the safety and efficacy of Gp96 vaccination in adjuvant settings for patients with gastric cancer. Methods: Consecutive patients from November 2012 to December 2015 were enrolled. Participants were allocated to the experimental group or control group, receiving Gp96 vaccination plus chemotherapy or chemotherapy alone respectively. The primary endpoints were disease-free survival and toxicity. The secondary outcomes were overall survival and tumor-specific immune responses. Results: Thirty-nine and forty patients received Gp96 vaccination plus chemotherapy and chemotherapy alone in the adjuvant settings respectively. Significant increased tumor-specific immune responses were observed after Gp96 vaccination. There were comparable disease-free survival ( p = 0.413; HR: 0.75; 95% CI: 0.37−1.48) and overall survival ( p = 0.485; HR: 0.68; 95% CI: 0.24−1.96) between experimental group and control group. In subgroup of patients with stage II and stage III gastric cancer, patients who have received Gp96 vaccination had improved disease-free survival compared those who have not ( p = 0.044; HR: 0.45; 95% CI: 0.22−0.96). Gp96 vaccination plus chemotherapy was well tolerated and no Gp96-related serious adverse event has been observed. Conclusions: Gp96 vaccination could elicit tumor-specific immune responses and could be safely used in adjuvant settings combined with chemotherapy. Patients with less aggressive diseases might benefit from Gp96 therapy.

311 Background: There is a lack of research on newly developed sarcopenia postoperatively. The purpose of this study was to investigate the risk factors and the clinical impact of postgastrectomy sarcopenia on the prognosis in patients undergoing radical gastrectomy for gastric cancer (GC). Methods: We retrospectively reviewed clinicopathological data from 430 consecutive GC patients who underwent surgical resection at Chung-Ang University Hospital between January 2011 and December 2015. Their skeletal muscle mass and abdominal fat volume were measured by abdominal CT imaging. Results: A total of 425 patients were analyzed in the study. The mean age was 62 years old and male were 301 (70.8%). Of these, 42 patients (9.9%) were diagnosed as pre-operative sarcopenia. Compared with non-sarcopenic group, pre-operative sarcopenia groups showed more female, higher BMI, less alcoholic, and less smoking. However, there was no significant difference in 5 - year overall survival and disease free survival between the groups (p = 0.836 and p = 0.638, respectively). Among 381 non-sarcopenic patients, 48 patients (12.6%) were diagnosed as newly developed sarcopenia in one year after gastric resection. Compared with non-sarcopenic group, the newly developed sarcopenic group showed more male, more undifferentiated tumor, lower hemoglobin level, less alcoholic, less smoking, and presence of diabetes mellitus. However, there was no significant difference in the 5 - year overall survival and disease free survival among non-sarcopenic, sarcopenic, and newly developed sarcopenic groups (p = 0.521 and p = 0.534, respectively). The relationship between preoperative body fat volume and postoperative muscle mass showed a significant correlation (rho = 0.296, p < 0.001), but only BMI was significantly associated with long term survival. Conclusions: Although newly developed sarcopenia after surgery did not affect the survival rate, patients with nutritional risk of sarcopenia after surgical resection may require early evaluation of nutritional status and nutritional support.

PURPOSE In a randomized clinical trial (European Organization for the Research and Treatment of Cancer [EORTC] no. 40813) on adjuvant chemotherapy in gastric cancer, results obtained after administration of the FAM2 regimen (fluorouracil [5-FU], doxorubicin, and mitomycin) were compared with results obtained after surgery alone to assess the effect of this regimen on overall survival, time to progression, and disease-free interval. PATIENTS AND METHODS Three hundred fourteen patients who had undergone curative resection for stage II or stage III (International Union Against Cancer [UICC] 1978) gastric adenocarcinoma were randomized to receive chemotherapy (treatment arm) or no further treatment (control arm). The chemotherapy schedule was repeated every 43 days for seven cycles. The log-rank test and the Cox model were used for statistical analysis. RESULTS Of 314 patients, 159 comprised the control group and 155 the FAM2 group. Nineteen FAM2 patients never received chemotherapy. The median number of cycles was five. Of the patients started on adjuvant treatment, severe hematologic and nonhematologic toxicity (grades 3 or 4, World Health Organization [WHO] scale) occurred, respectively, in 6% to 9% and in 1% to 29% of cases. The overall 5-year survival rate was 70% for stage II and 32% for stage III patients. No statistically significant difference was found between overall survival of the two treatment arms (P = .295). However, time to progression was significantly delayed in the FAM2 arm (P = .020) and disease-free survival showed borderline significance (P = .068). CONCLUSION FAM2, in view of its high toxicity, cannot be advocated as standard adjuvant treatment for gastric cancer. Large-scale clinical trials using more active, less toxic regimens are required to demonstrate whether adjuvant chemotherapy provides any real benefit.
