15159 Background: Increased disease free and overall survivals were seen in curatively resected patients with gastric and gastroesophageal adenocarcinoma treated with postoperative adjuvant CRT compared to surgery alone. There is no study analyzing the outcome of gastric cancer patients who received adjuvant CRT after curative resection in Turkish patients. Thus, we aimed to analyze the treatment outcome of postoperative CRT, and the prognostic significance of various parameters in these patients. Material Metod: Overall 130 patients with gastric cancer staged IB to IV(M0) were treated with chemoradiotherapy after curative resection, in two outpatient clinics in Istanbul. The chemotherapy consisted of fluorouracil 425 mg/m2 plus leucovorin 20 mg/m2 for 5 days, followed by 4500 cGy of radiotherapy for 5 weeks with fluorouracil (400 mg/m2) and leucovorin (20 mg/m2) on the first 4 days and the last 3 days of radiotherapy. Two 5-day cycles of chemotherapy with the doses used in the first cycle were given 4 weeks after the completion of radiotherapy. The demographic features and histopathological characteristics of the patients were analyzed as prognostic factors. Results: The median follow up was 13 months (range: 1–77) starting from surgery date. The median age was 58 years (range:33–75). About 28 % of the patients were female. ECOG performance score (PS) was =1 in 92.9 %, whereas it was 2 in the remaining 7.1%. Twenty-one patients had gastroesophageal junction and 109 had gastric primaries. The rates of T1, T2, T3, and T4 tumors were 3.8%, 26.9%, 61.5%, and 7.7%, respectively. A hundred and nine (83.8%) patients had regional node involvement. The 3 year disease free survival and overall survival for all patients were 50.1%, and 61.7%, respectively. The median overall survival was 54 months. In multivariate Cox regression analysis; nodal status (p: 0.003) was the only independent prognostic factor for overall survival. Tolerance was acceptable, and the main toxicity was related to gastrointestinal system. Conclusion: The adjuvant CRT after curative resection of gastric cancer was feasible, with acceptable toxicities in our Turkish patient population. No significant financial relationships to disclose.

Background: Inflammation plays an important role in tumor progression. Predicting survival is remarkably difficult in patients with gastric cancer receiving neoadjuvant chemotherapy. The aim of the present study is to investigate the potential prognostic significance of the platelet-to-lymphocyte ratio in patients with gastric cancer receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen. Methods: Ninety-one patients with gastric cancer treated with neoadjuvant chemotherapy were enrolled in this study and then underwent operation. The optimal cutoff value was calculated using receiver-operating characteristic curve analyses. The optimal cutoff value of platelet-to-lymphocyte ratio was divided into low platelet-to-lymphocyte ratio <162 group and high platelet-to-lymphocyte ratio ≥162 group. Kaplan-Meier method and log-rank test were used to analyze the survival curves. The independent prognostic factors and prognostic value of the platelet-to-lymphocyte ratio were assessed by univariate and multivariate Cox proportional hazards regression model. The toxicity was evaluated according to the National Cancer Institute Common Toxicity Criteria. Results: Kaplan-Meier analyses revealed that patients with low platelet-to-lymphocyte ratio correlated remarkably with better mean disease-free survival and mean overall survival than those with high platelet-to-lymphocyte ratio (mean disease-free survival 47.33 and 33.62 months, respectively; mean overall survival 51.21 and 36.80 months, respectively). The results demonstrated that platelet-to-lymphocyte ratio had prognostic significance using the cutoff value of 162 on disease-free survival and overall survival, and the mean disease-free survival and overall survival time for patients with low platelet-to-lymphocyte ratio were longer than those with high platelet-to-lymphocyte ratio. Meanwhile, patients with gastric cancer who had lower platelet-to-lymphocyte ratio had longer 1-, 3-, and 5-year rates of disease-free survival and overall survival. Moreover, patients with low platelet-to-lymphocyte ratio had longer mean disease-free survival and overall survival than those with high platelet-to-lymphocyte ratio in receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen. Conclusions: The preoperative platelet-to-lymphocyte ratio may be a promising and convenient prognostic biomarker for patients gastric cancer receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen neoadjuvant chemotherapy. It may be useful to help the doctors identify the high-risk patients for taking efficient treatment strategy decisions.

Abstract Background: MicroRNAs (miRNAs) may function either as oncogenes or tumor suppressors and are heavily involved in the initiation and progression of cancer, and in metastasis of tumor cells. MicroRNA-28-5p (miR-28-5p) targets several cancer-related genes and is hence involved in cell proliferation, migration, invasion and epithelial-mesenchymal transition. In this study, we investigated the potential diagnostic and prognostic significance of miR-28-5p expression in colorectal adenocarcinoma, the most frequent type of colorectal cancer (CRC). Methods: Therefore, we isolated total RNA from 182 colorectal adenocarcinoma specimens and 86 paired non-cancerous colorectal mucosae. After polyadenylation of 2 μg total RNA and its reverse transcription using an oligo-dT-adapter primer, we quantified miR-28-5p levels using an in-house-developed reverse-transcription real-time quantitative polymerase chain reaction (RT-qPCR) method, based on the SYBR Green chemistry. Results: Comparison of miR-28-5p levels among 86 pairs of colorectal tumors and their adjacent non-cancerous mucosae uncovered the downregulation of miR-28-5p expression in the majority of malignant colorectal tumors. More importantly, high miR-28-5p expression predicts poor disease-free survival (DFS) and overall survival (OS) of colorectal adenocarcinoma patients. Multivariate Cox regression analysis revealed that miR-28-5p overexpression is a significant predictor of poor prognosis in colorectal adenocarcinoma, independent of tumor size, histological grade, TNM staging, radiotherapy and chemotherapy. Interestingly, strong miR-28-5p expression retains its predictive potential regarding relapse among patients with negative regional lymph nodes, and predicts poor OS in patients diagnosed with non-metastatic colorectal adenocarcinoma. Conclusions: High miR-28-5p expression predicts poor DFS and OS of colorectal adenocarcinoma patients, independently of clinicopathological prognosticators and standard patient treatment, including radiotherapy and chemotherapy.

CONTEXT: Patients receiving adjuvant chemotherapy for breast cancer have a tendency to gain weight. This tendency has determining factors not completely defined and an unknown prognostic impact. OBJECTIVE: To evaluate weight change during chemotherapy for breast cancer in a defined population and to identify its predisposing factors and possible prognostic significance. DESIGN: Observational, retrospective cohort study. SETTING: Private clinical oncology service. PARTICIPANTS: 106 consecutive patients with breast cancer treated between June 1994 and April 2000, who received neoadjuvant (n = 8), adjuvant (n = 74) or palliative (n = 24) chemotherapy. INTERVETION: Review of medical records and gathering of clinical information, including patients’ body weights before treatment and at follow-up reviews. MAIN MEASUREMENTS: Body weight change, expressed as percentage of body weight per month in treatment; role of clinical data in weight change; and influence of weight change in overall survival and disease-free survival. RESULTS: There was a mean increase of 0.50 ± 1.42% (p = 0.21) of body weight per month of treatment. We noted a negative correlation between metastatic disease and weight gain (r = -0.447, p < 0.0001). In the adjuvant and neoadjuvant therapy groups there was a mean weight gain of 0.91 ± 1.19 % (p < 0.00001) per month, whereas in the metastatic (palliative) group, we observed a mean loss of 0.52 ± 1.21% (p = 0.11) of body weight per month during the treatment. We did not observe any statistically significant correlation between weight changes and disease-free survival or overall survival. CONCLUSIONS: Women with breast cancer undergoing adjuvant or neoadjuvant chemotherapy gain weight, whereas metastatic cancer patients will probably lose weight during palliative chemotherapy. Further studies are needed in order to evaluate the prognostic significance of weight changes during chemotherapy.

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.

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.

Objective. Gastric cancer is a malignant tumor originating from gastric mucosal epithelium. Here, we aimed to investigate the analysis of the threshold change of gastric cancer tumor mutation burden (TMB) and its relationship with the prognosis of patients. Methods. 256 patients with gastric cancer were selected as subjects. All patients were in the advanced stage and received surgical resection of D2 lymph node dissection. After the operation, a follow-up was performed for 24 months, and the disease-free survival and overall survival of patients were counted. The NGS molecular biological was detected to obtain gastric cancer tumor mutation burden (TMB) data. Pearson correlation analysis software was used to analyze the correlation between TMB threshold and disease-free survival or overall survival of patients with gastric cancer, and the multivariate logistic analysis was performed as well. Results. The disease-free survival period and the overall survival period of patients in the low-to-medium TMB group were both longer than those in the high TMB group. Pearson correlation analysis results showed that the TMB threshold was negatively correlated with the disease-free survival and overall survival of gastric cancer patients. Results from multivariate logistic analysis showed that high TMB thresholds have a greater impact on disease-free survival and overall survival of patients, but the impact of medium and low TMB thresholds on disease-free survival and overall survival of patients is weakened. Conclusions. The TMB threshold level has a predictive effect on the effect of surgical resection of D2 lymph node dissection, and high levels of TMB can significantly affect disease-free survival and overall survival of patients with advanced gastric cancer.

Gastric cancer (GC) is the second most common cancer and the third most frequent cause of cancer-related deaths in China. E2Fs are a family of transcription factors reported to be involved in the tumor progression of various cancer types; however, the roles of individual E2Fs are still not known exactly in tumor progression of GC. In this study, we examined the expression of E2Fs to investigate their roles in tumor progression in GC patients using multiple databases, including ONCOMINE, GEPIA2, Kaplan-Meier plotter, cBioPortal, Metascape, LinkedOmics, GeneMANIA, STRING and UCSC Xena. We also performed real-time polymerase chain reaction (RT-PCR) to validate the expression levels of individual E2Fs in several GC cell lines. Our results demonstrated that the mRNA levels of E2F1/2/3/5/8 were significantly higher both in GC tissues and cell lines. The expression levels of E2F1 and E2F4 were correlated with poor overall survival (OS), decreased post-progression survival (PPS), and decreased progression-free survival (FP) in patients with GC. However, overexpression of E2F2, E2F5, E2F7 and E2F8 is significantly associated with disease-free survival and overall survival in patients with GC. In addition, higher E2F3 and E2F6 mRNA expression was found to increase GC patients’ OS and PPS. 224 of 415 patients with STAD (54%) had gene mutations that were associated with longer disease-free survival (DFS) but not OS. Cell cycle pathway was closely associated with mRNA level of more than half of E2Fs (E2F1/2/3/7/8). There were close and complicated interactions among E2F family members. Finally, our results indicated the gene expressions of E2Fs had a positive relationship with its copy numbers. Taken together, E2F1/2/3/5/8 can serve as biomarkers for GC patients with high prognostic value for OS of GC patients or therapeutic targets for GC.
