14090 Background: The free abdominal cancer cells in the patients with gastric cancer probably result in peritoneal dissemination. In Japan, the detection of free abdominal cancer cells at Douglas cavity is usually examined immediately after lapalotomy for advanced gastric cancer, because this procedure is recommended in Japanese Classification of Gastric Carcinoma 1999 provided by Japanese Gastric Cancer Association. The patients detected free abdominal cancer cells are diagnosed as stage IV, even if they undergo the surgical curative operation. However some of them have relatively long survival. We investigated that the amount of free abdominal cancer cells or histological type might affect their prognosis. Methods: Surgeon collected 50ml of saline with which Douglas cavity was irrigated. Pathologist stained cells by Papanicolaou follwed by differential centrifugation (2000G for 5 minutes) of saline. Among all 492 patients who underwent surgery for gastric cancer in our institute between 2000 and 2004, 46 patients underwent the curative surgery except free abdominal cancer cells. We investigated the amount of free abdominal cancer cells and histological type as the factors to affect prognosis of these 46 patients. The log-rank test was used to evaluate the survival curves calculated by Kaplan-Maier method. Results: 5 or less and more than 5 cancer cells per 1 cm2 were microscopically detected in 22 (Group A) and 24 patients (Group B), respectively. The median survival time (MST) of Group A and B were 877 and 384 days, respectively (P=0.16). The two-year survival rates of Group A and B are 63.7% and 27.2%, respectively. The cancer cells diagnosed histologically as differentiated and undifferentiated type were detected in 13 (Group X) and 33 patients (Group Y), respectively. The MSTs of Group X and Y were 877 and 383 days, respectively (P=0.13). The two-year survival rates of Group X and Y are 82.1% and 28.9%, respectively. Conclusions: In patients who have advanced gastric cancer with free abdominal cancer cells, a larger number or undifferentiated type of cancer cells may reduce the survival periods of patients with curative resection. No significant financial relationships to disclose.

Purpose: To compare fluorouracil (FU) alone with FU plus cisplatin (FP) and with uracil and tegafur plus mitomycin (UFTM) for patients with advanced gastric cancer in a prospective, randomized, controlled trial. Patients and Methods: A total of 280 patients with advanced gastric cancer were randomly allocated and analyzed for survival, response, and toxicity. The survival curves were compared between groups by log-rank test on an intent-to-treat basis. Results: At the interim analysis, the UFTM arm showed a significantly inferior survival with higher incidences of hematologic toxic effects than did control arm FU alone, and the registration to UFTM was terminated. Both investigational regimens, FP and UFTM, had a significantly higher incidence of hematologic toxic effects than FU alone, although the effects were manageable. The overall response rates of the FU-alone, FP, and UFTM arms were 11%, 34%, and 9%, respectively. The median progression-free survival was 1.9 months with FU alone, 3.9 months with FP, and 2.4 months with UFTM, respectively. Although FP demonstrated a higher response rate (P < .001) and longer progression-free survival than did FU alone (P < .001), no differences in overall survival were observed between the arms. The median survival times and 1-year survival rates were 7.1 months and 28% with FU, 7.3 months and 29% with FP, and 6.0 months and 16% with UFTM, respectively. Conclusion: Neither investigational regimen, FP nor UFTM, showed a survival advantage as compared with FU alone. FU alone will remain a reference arm in our future trial for advanced gastric cancer.

18 Background: The mechanism underlying tumor recurrence following curative surgery remains unclear. It is believed that intraperitoneal free cancer cells leaked into peritoneal cavity during curative surgery play an important role. In gastric cancer, new strategies should be established towards preventing leakage of cancer cells from the primary tumor involved tissues. Our previous research demonstrated the existence of disseminated cancer cells in the mesogastrium, and we proposed laparoscopic D2 lymphadenectomy plus complete mesogastrium excision (D2+CME) as an optimized surgical procedure for advanced gastric cancer (AGC). By dissecting along the surgical planes and embryonic boundary of mesogastrium, D2+CME is repeatable with less blood lost and improved short-term surgical outcomes. In this study, we further evaluated the oncological effect of D2+CME based on the detection of “cancer leak”. Methods: The peritoneal washings were collected prior to and after tumor resection from 45 patients who underwent D2+CME (D2+CME group) and 46 patients who underwent conventional D2 lymphadenectomy (D2 group). RT-PCR was used to determine the presence of cancer cells. Positive samples are defined as those with CEA mRNA level over threshold (cutoff value). Results: Of 91 peritoneal washing samples obtained before gastrectomy, 84 (41 in D2+CME; 43 in D2 alone) showed no presence of cancer cell. After gastrectomy, CEA positive was detected in 17 of 43 (39.5%) samples with D2 group, however, only 5 of 41 (12.2%) samples in D2+CME group detected positive CEA. The average level of CEA expression in D2+CME group was also significant lower than that in D2 group after gastrectomy (p < 0.05). Presence of “cancer leak” was closely associated with pT stage and surgical procedures. The DFS of patients with CEA positive after gastrectomy was significantly poorer than that of patients with CEA negative (p < 0.05). Conclusions: LaparoscopicD2+CME could reduce the leakage of free cancer cells from the envelop of mesogastrium into the peritoneal cavity during radical gastrectomy, and thus, it might potentially increase the prognosis of AGC patients. Clinical trial information: NCT01978444.

Abstract Objective: The aim of this study was to clarify the prognostic value of the pathological lymph node ratio for elderly and non-elderly gastric cancer patients and to evaluate whether there is a difference in the survival of patients with the same LNR (Lymph Node Ratio).Materials and Methods: A total of 222 patients diagnosed with locally advanced gastric cancer and who underwent gastrectomy were included. The patients were divided into two groups according to age. Clinicopathological properties of the two groups were compared. Potential prognostic factors affecting survival were analyzed. Subsequently, the effect of lymphadenectomy and LNR on survival in both groups was evaluated. Results: Significant differences were detected in terms of the location of primary lesions, hemoglobin and albumin levels between elderly patients and non-elderly patients (p < .05). Overall survival (OS) was significantly worse in elderly patients (22 months vs. 67 months, p<0.001). The survival rates in elderly patients were significantly lower from those of non-elderly in the subgroup LNR Stage 2 (12.1% vs. 47.9 %, P = 0.004) and LNR Stage 3 classification (9.1% vs. 34.1%, P = 0.039). LNR was found to be significant for OS with a cut-off point of 0.18. Conclusion: A survival difference was found between the elderly and non-elderly patients with the same LNR. LNR was found to be an independent factor for survival especially in elderly patients. Survival was found to be further decreased in elderly patients compared to non-elderly patients with increasing LNR.

e16019 Background: Postoperative adjuvant chemotherapy is commonly given after the curative resection of gastric cancer (GC) in both Eastern and Western countries. Several studies have investigated the feasibility and safety of S-1 plus docetaxel or S-1 plus cisplatin. However, the best choice of adjuvant treatment for patients with gastric cancer is still debated. Apatinib, an oral small molecular of VEGFR-2 TKI, has been confirmed to improve OS and PFS with acceptable safety profile in patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy. In this study, we aimed to evaluate the efficacy and safety of apatinib combined with S-1/docetaxel for locally advanced gastric cancer (T3-4aN+M0). Methods: This is a prospective, randomized, controlled, multicenter clinical study. Patients with locally advanced gastric cancer, pathological stage T3-4aN+M0 who underwent D2 lymphadenectomy without prior anti-cancer therapy were included. All these patients were assigned to group A or B. Patients in group A received 6 cycles (21 days a cycle) of adjuvant therapy using S-1 (80-120mg/d, d1-14), and docetaxel (40mg/m2, d1). Group B received the same regimen with the addition of apatinib (250mg, qd.). The primary endpoint was disease-free survival (DFS). The final analysis cutoff date was 30 November, 2020. Results: A total of 45 patients were enrolled from January 2019 to November, 2010 and assigned to group A (21) or group B (24). The DFS was not reached in both of the groups. The 1-year disease-free survival rate was 60% in group A and 90% in the group B, while the difference was not significant. The main AEs in group A were anemia (55%), nausea (50%) and neutropenia (40%); The most common AEs in group B were anemia (45%) neutropenia (40%) and diarrhea (25%). There were no treatment-related deaths. The longest administered time of apatinib with no progression was 457 days. And the median time to receive apatinib was 329 days. Conclusions: Combination of apatinib with S-1/docexal chemotherapy shows clinical benefits in locally advanced gastric cancer (T3-4aN+M0), with tolerable toxicity. The study is still ongoing to reach our final endpoint, DFS. Clinical trial information: ChiCTR2000038900.

e20019 Background: Historically, melanoma with brain metastases has a poor prognosis and is a major contributor to patient morbidity and mortality. Recently, the use of ipilimumab has improved overall survival in stage IV melanoma; however, the outcome of patients with brain metastases remains unclear. In this retrospective medical record review, we report the outcome of patients with stage IV melanoma with brain metastases treated with ipilimumab and brain stereotactic radiosurgery (SRS). Methods: All patients with metastatic melanoma treated with ipilimumab from April 2010 to March 2012 were identified and stratified by presence (A) or absence (B) of brain metastases. All patients with brain metastases received SRS. Performance status, dates of stage IV diagnosis, brain SRS and cycle 1 of ipilimumab administration were recorded. We used the Disease Specific Graded Prognostic Assessment (DS-GPA) to estimate the predicted survival. Overall survival was defined as time (months) from the date of the stage IV diagnosis and the time of ipilimumab administration to death or last follow-up. Survival curves were estimated using the Kaplan-Meier method, and compared using a two-tailed log-rank test. Results: Twelve of 30 patients treated with ipilimumab had brain metastases. Median age was 66 years. Median DS-GPA score was 3 (estimated mean survival of 8.7 months). Four patients (33%) in group A and 6 patients (33%) in group B died as of last follow-up. Median number of SRS treatment was 1 (1 to 4), and median total treated lesions were 3 (1-14). Median survivals from date of Stage IV for A and B were 29.1 and 32.9 months, respectively (p=0.67). The estimated 2 year survival rates from date of cycle 1 ipilimumab administration for A and B were 58% (95% CI: 32-100%) and 55% (95% CI: 32-93%), respectively. Ten out of 12 patients in group A maintained an ECOG PS of 0-1 as of last follow-up. Conclusions: Survival of patients with melanoma brain metastases treated with ipilimumab combined with SRS may be comparable to patients without brain metastases. Ipilimumab and SRS do not seem to adversely impact quality of life.

e15524 Background:The predictive value of tumor markers has been previously reported a lot. However, the studies focused on advanced gastric cancer are few. In this study, we tried to investigate the relationship between the tumor markers of advanced gastric cancer and clinical characteristics, therapeutic effect of chemotherapy, and prognosis. Methods:A retrospective study including 146 advanced gastric cancer who had not received any previous anticancer therapy was performed. Blood samples for CEA, AFP, CA125, CA72-4, CA242 and CA19-9 were taken from patients before chemotherapy and monthly during their treatments. Statistical analysis was performed to predict the clinical value of these tumor markers. Results:CEA yielded an ROC value of 0.621 in predicting lymph node metastasis in gastric cancer, which was significantly higher than any of other markers. CA125 had the highest sensitivity, specificity and accuracy in gastric cancer patients with peritoneal metastasis. AFP and CEA were more frequently positive in patients with hepatic metastases. The response rate of Decreasing group, Stable group and Increasing group based on CA19-9, CEA, CA72-4, CA125 and CA242 levels achieved statistical significance. Positive cases of CA125, CA242, CA19-9 and CA72-4 showed poor prognosis, and significant differences in 3 year-survival rates were observed for CA125 and CA242. Conclusions:We found that different tumor markers in gastric cancer indicated different metastasis sits. CEA, CA242, CA19-9, CA125 and CA72-4 are predictive biomarkers in evaluating the effectiveness of chemotherapy. The elevated CA125, CA242, CA19-9 and CA72-4 levels at diagnosed had association with shorter overall survivals, especially CA125 and CA242.

AbstractPresence of free gastric cancer cells in the peritoneal cavity of patients who underwent surgical treatment for gastric cancer is a negative prognostic factor and caused rapid disease recurrence, manifested as peritoneal metastases.Positive peritoneal cytology despite lack of visible peritoneal metastases was regarded as M1 class in the TNM classification (7was to analyze factors associated with positive peritoneal cytology and identify groups of patients in whom diagnostic laparoscopy plus peritoneal lavage in the diagnostic process could affect therapeutic decisions.The study enrolled patients with gastric cancer who underwent surgical treatment at the Department of Surgery, Wielkopolskie Oncology Center in Poznań. During the laparotomy, after opening of the peritoneal cavity, 200 ml of physiological saline at 37°C was administered in the tumor region. After this fluid was mixed, 100 ml of lavage fluid was collected. This fluid was subsequently spun many times to obtain sediment for cytology and immunohistochemistry investigation using anti-BerEp-4, CK 7/20, and B72.3.Results of peritoneal cytology were analyzed jointly with clinical factors – patient’s age, sex and pathology factors – tumor invasion, involvement of lymph nodes, histological grade, histological type according to Lauren and localization of the cancer in the stomach.Analysis of the peritoneal fluid for presence of free cancer cells was done in 51 patients. Positive peritoneal cytology was found in 12 (23.5%) patients. In the group of patients with positive cytology, all patients had T3/T4 tumors and all were found to have lymph node metastases, while G3 cancer was found in 83.3% of patients. In patients with positive cytology, diffuse gastric cancer according to Lauren predominated (9 of 12 patients, 75%), while in patients with negative cytology – intestinal type (20 of 39 patients, 51.2%). In the group of patients with positive histology, the whole stomach was involved by the cancer process in 7 of 12 patients (58.3%), while in the group with negative histology, in 29 of 39 patients the tumor was located in the gastric body and prepyloric part (74.4%).Based on this study we can conclude that determinants of positive peritoneal cytology include: tumor stage T3/T4, N+, G3, cancer located in the whole stomach, diffuse histological type according to Lauren.

Introduction: Gastric cancer is the fourth most common cancer and the second leading cause of death in the world. Despite the recent advances in controlling and treating the disease, the survival rate of this cancer is relatively low. Various factors can affect the survival of the patients with gastric cancer. The aim of this study was to determine the survival rates and the effective factors in the patients with gastric cancer. Methods: The study population included all the patients diagnosed with gastric cancer in Hamadan Province who were referred to Hamadan Imam Khomeini Specialized Clinic between 2004 to 2017. Patients were followed up by periodical referrals and/or telephone contact. The survival rate of the patients was calculated using Kaplan-Meier method and effective survival factors with Cox proportional regression. Data were analyzed using SPSS 23 software at a significance level of 0.05. Results: Out of the 350 patients with gastric cancer, 74.3% were male and 25.7% were female. One-year, three-year and five-year survival rates were 67%, 36% and 27%, respectively. The log -rank test showed that age, type of tumor, stage of disease, type of Surgery and metastasis of the disease were effective on the survival of patients. In Cox's multivariate analysis, the only age variables at the time of diagnosis and chemotherapy were survival variables. (P<0.05). Conclusion: The results of this study showed that age variable is a strong factor in survival, so it is essential to diagnose the disease at the early age and early stages of the disease using a screening program.

Introduction: Gastric cancer is the fifth most commonly diagnosed tumor and is the fourth leading cause of cancer-related mortality, worldwide. Due to the low rate of early diagnosis, approximately two-thirds of patients are first diagnosed at an advanced stage. Neoadjuvant chemotherapy (NAC) is recommended for patients with advanced gastric cancer (AGC). The neutrophil-to-lymphocyte ratio (NLR), a combined inflammatory and immunogenic factor, has been universally used for predicting outcomes in AGC patients. Given that NLR is a dynamic process, in this study, we investigated the value of NLR change for the prediction of chemotherapeutic responses and prognosis in patients with AGC.Methods: We retrospectively enrolled 111 patients with AGC who underwent NAC following curative surgery. Patients were divided into two groups according to the NLR change after chemotherapy into the increased and decreased groups. Outcome measures were overall survival (OS) and disease-free survival (DFS). Univariate was calculated by Kaplan-Meier method. Multivariate analysis was performed using the Cox proportional hazards regression model.Results: Post-chemotherapy, NLR increased in 36 patients and decreased in 75 patients. After a median follow-up time of 19 months, six patients developed local recurrence, 23 developed distant recurrence, and 34 died. Patients with reduced post-chemotherapy NLR showed significantly longer OS (p &lt; 0.001) and DFS (p &lt; 0.001). A decrease in the NLR after NAC was an independent indicator associated with better OS (p &lt; 0.001) and DFS (p &lt; 0.001).Conclusions: In patients with AGC, a decrease in NLR after NAC indicated better survival. NLR change could serve as a robust indicator for the efficiency of NAC and prognostic prediction in patients with AGC.
