Background: 5-fluorouracil (5-FU) is basically used in the field of postoperative chemotherapy of gastric cancer (GC), the goal of this study was to evaluate improvement of long-term survival rate among GC patients after the 5-FU implants treatment.Methods: The study included 145 patients with gastric cancer who received postoperative chemotherapy with 5-FU implants and had complete follow-up information. According to the sex, age and clinical stage of 5-FU implants group, 74 patients were matched as the control group at the same time. In the study, we compared the 5-year overall survival rate with progression-free survival rate in the two groups, and the drug safety for both groups during the treatment was also compared.Results: The median follow-up time was 85 months (range 60–116 months). 31 patients (21.38%) died of tumor recurrence in 5-FU implants group and 21 (28.38%) in control group. In the control group, metastatic lesions were found in the small intestine, left adrenal gland and peritoneum in three patients. The 5-year progression-free survival (PFS) rate was 79.71% in 5-FU group and 67.12% in control (p = 0.0045). The 5-year overall survival (OS) rate was 77.68% in 5-FU implants group and 64.87% in control (p = 0.0159). Both the 5-years OS and PFS rates in 5-FU group were better than control group without significant side effect.Conclusions: 5-FU implants may improve 5-years OS and PFS rates after surgery in gastric cancer patients, while good safety profile suggests it could be reliable.

Purpose:to study clinical and subclinical characteristics in advanced stage gastric cancer patients and to evaluate response rate, overall survival, progression free survival and toxicities on advanced stage gastric cancer patients treated with first line chemotherapy using epirubicin, oxaliplatin, capecitabin Methods: A retrospective case series study with 134 advanced stage gastric cancer patients on first line chemotherapy using epirubicin, oxaliplatin, capecitabin recruited from oncology department, the Hospital of Hue University of Medicine and Pharmacy and Cancer Center at Hue Central Hospital during January 2015 to June 2019. Results: Patient’s mean age was 54,9; men/women was 2,52/1. The most frequent clinical symptom reported was epigastric pain 81,3%. KPS 80-90% presented in almost patient (93.3%). The most common site of cancer was pyloric antrum (61,9%). 58,2% patients had distant metastasis disease which liver was the most frequent site. The overall response rate, partial response rate, complete response rate were 49,2%, 42,5%, 6,7% respectively. The median progression free survival was 8,6 ± 0,15 months and the overall survival was 10,7 ± 1,1 months. The pathologic type and combined salvage surgery status were response correlated factors. Grade 3, 4 toxicities in term of hematology, liver and kidney function were only exhibited in a few cases. Patients were tolerated well with chemotherapy. No deaths related to chemotherapy. Conclusions: This study shows that EOX regimen was safe and effective. As a results, we can apply this for first line pallative chemotherapy on advanced stage gastric cancer which KPS ≥70%.

Objective. We performed a meta-analysis of available studies to assess the prognostic value of circulating tumor cells detected by cytological methods for patients with gastric cancer. Methods. Two authors systematically searched the studies independently with key words in PubMed, MEDLINE, EMBASE, Science Citation Index Expanded, and Cochrane Library (from inception to April 2016). The estimated hazard ratio, risk ratio, odds ratio, and their 95% confidence intervals were set as effect measures. All analyses were performed by STATA 12.0. Results. Sixteen studies were included in this meta-analysis. CTCs-high status was significantly associated with poor overall survival (HR=2.23, 95% CI: 1.86–2.66) and progression-free survival (HR=2.02, 95% CI: 1.36–2.99). CTCs-high status was also associated with depth of infiltration (OR = 2.07, 95% CI: 1.16–3.70), regional lymph nodes metastasis (OR = 1.85, 95% CI: 1.26–2.71), and distant metastasis (OR = 2.83, 95% CI: 1.77–4.52). For unresectable gastric cancer patients, CTCs-high status was significantly associated with poor overall survival, progression-free survival, and disease control rate before and during chemotherapy group. Conclusions. Our meta-analysis has evidenced the significant prognostic value of CTCs detected for both PFS and OS in gastric cancer patients. For patients treated with chemotherapy alone, we proved that CTCs detected by cytological method showed a significant prognostic value and poor response to chemotherapy.

Abstract Background: New blood vessel formation is a crucial step in the process of tumor growth and systemic metastasis. Recent studies have shown that VEGF expression not in tissues but in serum sample is correlated with tumor vascularity, and the high serum VEGF levels could predict poor prognosis in cancer patients. However there has been no data regarding the clinical and prognostic significance of serum VEGF levels per platelet count in advanced gastric cancer. In this study, we conducted a study to evaluate the prognostic implication of serum VEGF per platelet count in the patients with advanced gastric cancer. Methods: 111 patients with histologically confirmed gastric cancer, 35 patients with early gastric cancer were included and control serum samples were acquired from 25 healthy volunteers. The levels of VEGF were measured using human VEGF quantitative enzymelinked immunosorbent assay (ELISA). Survival curves were calculated using the Kaplan-Meier method and survival comparisons were made by the log rank test in metastatic gastric cancer. The Cox proportional hazards regression model was utilized for multivariate analyses after univariate analysis defined relevant prognostic variables. Results: The mean serum VEGF level was higher in the patients of AGC compared to those with EGC and controls (AGC 465 ± 315.8pg/ml; EGC 306 ± 97.8 pg/ml controls 230.8 ± 53.2 pg/ml, P< 0.033). A trend toward a significant positive correlation between serum VEGF and platelet counts was observed in patients of AGC (r = 0.477, P = 0.000, Fig 2) and there was a significant correlation between serum VEGF levels and differentiation of tumor (p = 0.014), stage (p = 0.036). The overall survival (log rank, p =0.0432) and the progression free survival (median 4.5 vs. 8.9 months; log rank, p =0.0116) were significantly shorter in patients with high VEGF per platelet count (≥1.626 pg/106). In the multivarivate analysis, performance status (P=0.025), the presence of peritoneal carcinomatosis (P=0.006), serum VEGF per platelet (P=0.005) were found to be significantly associated with the short progression free survival Conclusions: This study demonstrated that serum VEGF per platelet count is correlated with short overall survival and progression free survival in advanced gastric cancer patients. Therefore, serum VEGF per platelet may be a useful marker for predicting the prognosis of advanced gastric cancer patients.

Epigenetic modification of several genes is a key component in the development of gastric cancer. The methylation status of RASSF1A, SOX17 and Wif-1 genes was evaluated in the cell free circulating DNA of 70 patients with advanced gastric cancer, using methylation-specific PCR. Patients with higher cell-free DNA concentration seem to have lower PFS, than patients with lower cell-free DNA concentration (p = 0.001). RASSF1A was the tumor suppressor gene, most frequently methylated in metastatic gastric cancer patients, followed by SOX17 and Wif-1 (74.3%, 60.0% and 47.1%, respectively). Patients having the SOX17 promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p < 0.001). Patients having the Wif-1 promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p = 0.001). Patients having the RASSF1A promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p = 0.004). Promoter methylation of the examined genes was significantly associated with a decrease in progression free survival and overall survival, comparing to that of patients without methylation. Simultaneous methylation of the above genes was associated with even worse progression free survival and overall survival. The methylation of RASSF1A, SOX-17 and Wif-1 and genes, is a frequent epigenetic event in patients with advanced gastric cancer.

AbstractAimThis study aimed to evaluate and compare the efficacy and toxicity of common regimens used as perioperative chemotherapy including ECF, DCF, FOLFOX, and FLOT to identify the most effective chemotherapy regimen with less toxicity.Material and MethodsThis retrospective cohort study was based on 152 eligible gastric cancer patients recruited in a tertiary oncology hospital in Isfahan, Iran (2014-2019). All resectable gastric cancer patients who had received one of the four chemotherapy regimens including ECF, DCF, FOLFOX, or FLOT, and followed for at least one year (up to five years) were included. The primary endpoint of this study was Overall Survival (OS), Progression-Free Survival (PFS), Overall Response Rate (ORR), and R0 resection. We also considered toxicity according to CTCAE (v.4.0) criteria as a secondary endpoint. Cox -regression models were used applied to estimate OS and PFS time, controlled for relevant covariates.ResultsOf included patients, 32(21%), 51(33.7%), 37(24.3%), and 32(21%) had received ECF, DCF, FOLFOX and FLOT, respectively. After the median 25 months follow-up, overall survival was higher with the FLOT regimen in comparison with other regimens (hazard ratio [HR] = 0. 052). The median OS of the FLOT regimen was not reachable in Kaplan-Meier analysis and the median OS was 28, 26, and 23 months for DCF, FOLOFX, and ECF regimens, respectively. On the other hand, a median PFS of 25, 17, 15, and 14 months was observed for FLOT, DCF, FOLFOX, and ECF regimens, respectively (Log-rank = 0. 021). FLOT regimen showed 84. 4% ORR which was notably higher than other groups (p-value<0. 01).ConclusionsFor resectable gastric cancer patients, the perioperative FLOT regimen seemed to lead to a significant improvement in patients’ OS and PFS in comparison with ECF, DCF, and FOLFOX regimens. As such, the FLOT regimen could be considered as the optimal option for managing resectable gastric cancer patients.

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.

108 Background: An adjuvant chemotherapy with S-1 has become the standard treatment for patients (pts) with stage II/III gastric cancer (GC) who have undergone gastrectomy with D2 dissection in Japan, but it is assumed that the survival benefit for stage III pts who received S-1 is modest. S-1 plus docetaxel has shown that the response rate and median overall survival (OS) were 56% and 14.3 months in pts with advanced GC. The aims of this phase II study were to evaluate the feasibility and safety of adjuvant S-1 plus docetaxel in pts with stage III GC with D2 surgery. Methods: Pts with pathological stage III GC who underwent gastrectomy with D2 dissection received oral S-1 (80 mg/m2/day) administration for 2 consecutive weeks and intravenous docetaxel (40 mg/m2) on day 1, repeated every 3 weeks (1 cycle). The treatment was started within 45 days after surgery, and repeated for 4 cycles, followed by S-1 administration until 1 year after surgery. The primary endpoint was feasibility of the 4 cycles administration of S-1 plus docetaxel; secondary endpoints were safety, progression-free survival (PFS), OS, and feasibility of S-1 administration until 1 year after surgery. Results: We enrolled 53 pts, 42 males and 11 females with a median age of 65 years (range, 43-78), between May 2007 and August 2008. Pathological stages included IIIA in 36 pts and IIIB in 17 pts. The feasibility of planned 4 cycles of treatment was 77.4% (95% CI 63.8-87.7%, p < 0.001) with 41 pts out of 53 pts. Grade 4 neutropenia was observed in 28% of pts with grade 3 febrile neutropenia in 9%. Non-hematological toxicities of grade 3 or more involved fatigue in 6%, anorexia in 9%, and nausea in 6%. No treatment-related deaths occurred. Reasons for discontinuation were recurrent cancer in 1 pt, adverse events in 10, and miscellaneous in 1, respectively. 3 year overall survival was 78.8% (95% CI 68.4-90.7) and 3 year disease free survival was 50.3% (95% CI 34.4-73.3). Conclusions: Adjuvant S-1 plus docetaxel therapy is feasible and has only moderate toxicity in stage III gastric cancer pts. We believe that this regimen will be a candidate for future phase III trials seeking the optimal adjuvant chemotherapy for stage III gastric cancer patients.

Purpose The first planned interim analysis (median follow-up, 3 years) of the Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer confirmed that the oral fluoropyrimidine derivative S-1 significantly improved overall survival, the primary end point. The results were therefore opened at the recommendation of an independent data and safety monitoring committee. We report 5-year follow-up data on patients enrolled onto the ACTS-GC study. Patients and Methods Patients with histologically confirmed stage II or III gastric cancer who underwent gastrectomy with D2 lymphadenectomy were randomly assigned to receive S-1 after surgery or surgery only. S-1 (80 to 120 mg per day) was given for 4 weeks, followed by 2 weeks of rest. This 6-week cycle was repeated for 1 year. The primary end point was overall survival, and the secondary end points were relapse-free survival and safety. Results The overall survival rate at 5 years was 71.7% in the S-1 group and 61.1% in the surgery-only group (hazard ratio [HR], 0.669; 95% CI, 0.540 to 0.828). The relapse-free survival rate at 5 years was 65.4% in the S-1 group and 53.1% in the surgery-only group (HR, 0.653; 95% CI, 0.537 to 0.793). Subgroup analyses according to principal demographic factors such as sex, age, disease stage, and histologic type showed no interaction between treatment and any characteristic. Conclusion On the basis of 5-year follow-up data, postoperative adjuvant therapy with S-1 was confirmed to improve overall survival and relapse-free survival in patients with stage II or III gastric cancer who had undergone D2 gastrectomy.

Introduction. Hepatocellular carcinoma (HCC) is the most common primary malignant neoplasm of the liver. During the early stages, HCC is asymptomatic, which makes X-ray examination a particularly important diagnostic tool. According to WHO data, the mortality rate from HCC was 782,000 in 2018. HCC is associated with a number of risk factors: a high viral load, liver cirrhosis, detected HBeAg and elevated serum HBsAg levels. Inhibitors of tyrosine kinase receptors increase the overall survival and progression-free survival rates in patients with metastatic HCC. In this article, we conduct an analysis of results of the REFLECT study obtained for Russian patients by the Republican Clinical Oncological Dispensary, Ufa.Materials and methods. The experimental group included 9 patients (52.9%) receiving Lenvatinib. The control group included 8 patients (47.1%)) underwent therapy with Sorafenib at a dose of 800 mg per day 7 (41.17%) patients had a history of chronic hepatitis, of which hepatitis B and chronic hepatitis C was confirmed in 6 and 1 cases, respectively.Results and discussion. Over the period from 2017 up to the present, progression-free survival was observed in three patients (17.6%), of which 2 and 1 received Lenvatinib and Sorafenib, respectively. Overall survival was 10.5 months. The median overall survival rate in the experimental and control groups was 9.8 and 11.2 months, respectively. These parameters are considered comparable, provided that the sample was small.Conclusions. The use of Lenvatinib demonstrated the efficacy comparable to that of Sorafenib in terms of the overall survival rate in patients with inoperable HCC. Lenvatinib allowed statistically and clinically significant improvement in the progression-free survival and time to progression to be achieved.
