e15579 Background: More than 50% esophageal cancer cases of the world are in China. The main causative factors that contribute to extremely high incidence of esophageal cancer (9.15/ million) in certain rural areas of China has not yet been elucidated. Screening and diagnosis of precancerous lesions and early stage cancer are main neasures of decreasing incidence rate and mortality rate. Methods: High-risk population (40-69 years old) in high risk areas of esophageal cancer, Cixian and Yangcheng were screened, and 4742 cases were included. They were divided into 4 groups: normal group, esophagitis/gastritis, esophageal neoplasia low-level group and esophageal neoplasia high-level group, according to pathology and electronic gastroscope diagnosis. Diagnostic testing lingual information collection system (DS01-B) was used and tongue image were collected, including tongue color, coating color, fur character, tongue shape, local ecchymosis, et al. Difference of tongue image information was analyzed by multi-factor logistic regression using SPSS and R statistical software. Results: Logistic regression analysis showed that dark purplish tongue colour, and tongue local ecchymosis were correlated to precancerous lesions and early stage cancer (P < 0.01 or P < 0.05). Red and crimson tongue, yellow and white coated tongue, spotted tongue and tongue local ecchymosis were correlated to esophagitis and gastritis(P < 0.01 or P < 0.05). Logistic regression model had diagnostic total coincidence rate (69.4%) for early esophageal cancer screening. Conclusions: Multi-factor logistic regression model based on tongue image information has clinical value of prediction esophageal precancerous lesion.

e15583 Background: Individuals with gastric cancer (GC) are at risk for significant physical, psychological, and financial burden related to their illness and cost of care. This study characterizes cancer-related distress and concerns among survivors of GC and related cancers and the support survivors receive from their health care team for these concerns. Methods: Of 110 GC survivors enrolled in the Cancer Support Community’s online Cancer Experience Registry, 30 (43% stomach, 37% esophageal, 20% GIST) rated their level of concern (0 = not at all; 4 = very seriously) about psychological, emotional, physical and practical concerns (27 items). Risk for clinically significant distress was identified via a 4-item subscale (α = 0.86, cutoff score = 6.) Participants also completed the Impact of Events (IES) intrusion subscale and questions about their healthcare team’s involvement in addressing concerns. Results: Participant median age was 61 years; median time since diagnosis was 3 years. 23% experienced recurrence; 37% had metastatic disease.The highest ranked concerns (rated moderately to very seriously) included: eating and nutrition (62%); fatigue (62%); health insurance or money worries (59%); worry about the future (59%); feeling sad or depressed (50%); changes or disruptions to work, school, or home life (48%); sleep problems (48%); and worry about family (48%). Half of respondents (50%) were at risk for clinically significant emotional distress; 39% reported intrusive thoughts about the cost of cancer care. Fewer than half indicated their health care team asked about emotional distress (43%), lifestyle (43%), work (40%), finances (37%), or family (33%). Participants wished for more help with emotions related to cancer (57%), long-term side effects (55%), and financial advice/assistance (52%). Conclusions: Substantial proportions of gastric cancer survivors express concern about physical symptoms, emotional distress, and financial burden, yet many report they are not counseled about these concerns. Efforts are needed to reduce distress and the financial burden associated with gastric cancer to reduce their potential impact on quality of life, treatment adherence, and other illness outcomes.

e15588 Background: Chemotherapy (CT) and chemoradiotherapy (CTRT) both in neoadjuvant (neoadj) or adjuvant (adj) setting are associated with better overall survival (OS) over surgery alone in patients (pts) with resectable gastroesophageal (GE) adenocarcinoma (ADK). The best sequence and timing of treatments have still not been defined. A large cohort of GE ADKs derived from 2 high-volume Italian centers was analyzed to describe clinical outcomes and prognostic factors. Methods: 497 patients (pts) diagnosed with GE ADK who underwent surgery with curative intent from 2007 to 2016 were considered. Variables analyzed were: age, sex, tumor location, histology, T, N, M, R, G, HER-2, Helicobacter Pylori (HP) infection, (neo)adj CT, and adj CTRT. Analysis was performed according to ITT principle. Results: Median age at diagnosis was 71 years (range 35-92). At 26.7 months (mo) median follow-up, median OS was 27.6 mo (range 1-127) and median time to recurrence (TTR) 10.8 mo (range 7.8-13.1). Adj CT was administered in 203 cases (41%); 116 pts (23%) had adj CTRT and 47 (9%) neoadj CT. Statistically significant variables for OS and/or TTR at 12 months at univariate analysis were: age, T, N, M, R, G, adj CTRT, neoadj CT and adj CT. Results of multivariate analysis (MVA) are shown in Table 1. Conclusions: Despite a short follow-up, our analysis performed on a very large cohort of consecutive pts confirms the prognostic value of T and N for both OS and TTR. Adj CT and CTRT had a significant impact on 1 year OS, while neoadj CT gave only a 12 months TTR significant benefit. Based on these results, perioperative treatment strategies should always be considered in the management of resectable GE cancer. [Table: see text]

e15590 Background: The present study analyzed the expression of tumoral (t-) PD-L1/L2 and stromal (str-) PD-L1/L2, and their impacts on the survival of a relatively large group of Epstein-Barr virus (EBV)-associated gastric cancer (EBVaGC). Methods: After reviewing 1318 consecutive cases of surgically resected or endoscopic submucosal dissected gastric cancers, 120 patients were identified as EBV-positive using EBV-encoded RNA in situ hybridization. Immunohistochemistry of PD-L1 and PD-L2 was carried out and the intensity was scored as an intensity score 0 (no staining), 1 (weak intensity), 2 (intermediate intensity), and 3 (high intensity). The expression was also evaluated in tumor tissues and stromal immune cells and divided into two groups (2 and 3 were interpreted as a positive result). Results: Among the 120 patients, 57 patients (47.5%) and 66 patients (55.0%) were determined as t-PD-L1-positive and str-PD-L1 positive, while 23 patients (19.2%) and 41 patients (34.2%) were determined as t-PD-L2-positive and str-PD-L2 positive. In a univariate analysis, t-PD-L1-positive was significantly associated shorter disease-free survival (DFS, P = 0.032), yet not overall survival (P = 0.482). In a multivariate analysis using a Cox proportional hazard model adjusted for age, pTNM stage, gender, WHO classification, and tumor-infiltrating lymphocytes, t-PD-L1 positivity was independently associated with poor DFS (Hazard ratio = 4.183, P = 0.044). Meanwhile, in the univariate analysis, t-PD-L2-positive and str-PD-L2-positive showed a better DFS trend than t-PD-L2-negative and str-PD-L2-negative, respectively (P = 0.071 and P = 0.092). However, t-PD-L2 and str-PD-L2 expressions showed no prognostic significance on DFS in the multivariate analysis. Conclusions: The level of t-PD-L1 expression represents a significant difference for DFS in patients with EBVaGC. The current findings support the concept that PD-L1 may be a prognostic parameter for predicting patient outcome and act as a therapeutic target in EBVaGC.

e15592 Background: Molecular heterogeneity represents a significant hurdle in realizing precision medicine for gastric cancer (GC). Large-scale whole exome sequencing projects have identified distinct molecular subtypes to help define the heterogeneity of GC. However, it remains unclear whether the targeted gene panel-based sequencing can provide optimum targeted therapies and clinical utility in GC. The aim of this study is to generate comprehensive genomic profiling data and classify Japanese GC into actionable clusters associated with targeted therapies. Methods: FFPE tumor tissues were obtained from surgical or biopsy specimens of 207 Japanese patients with GC. Extracted DNA was subjected to genomic sequencing for 435 cancer related genes including 69 druggable genes with FDA approved targeted therapies. Somatic mutations, copy number alterations (SCNA), microsatellite instability (MSI) and Epstein-Barr virus (EBV) infection were evaluated using sequencing data. Results: Genomic sequencing identified at least one alteration of 435 genes in 194 pts (94%), and that of 69 druggable genes in 141 pts (68%). The most frequently altered druggable gene was ERBB2 (14%), following BRCA2 (11%) and ATM (10%). We successfully classified 207 tumors into four molecular subtypes, similar to the previously report; EBV (4%), MSI (8%), chromosomal instability (58%) and genomically stable subtype (30%). Frequent alterations of druggable genes ( > 5%) were widely observed through these subtypes. To discover the novel classifications associated with targeted therapies, we classified 207 tumors using mutation rate and hierarchical clustering. We identified a hypermutated group (n = 32), and a remaining non-hypermutated group (n = 175) which were sub-divided into six clusters including five actionable ones; ERBB2 (n = 25), CDKN2A and CDKN2B (n = 10), KRAS (n = 10), BRCA2 (n = 9) and ATM cluster (n = 12). Interestingly, we experienced a case of unresectable GC with a remarkable response for anti-HER2 therapy in the ERBB2 cluster. Conclusions: Genomic sequencing using a 435-gene panel has the potential to provide the information of optimum targeted therapies for upcoming precision medicine in Japanese GC.

e15594 Background: TNM staging system is not adequate to define the prognosis of patients with gastric cancer (GC). This system is also unable to predict whether the GC patients are likely to benefit from adjuvant chemotherapy. We postulated that ImmunoScore of GC (ISGC) could markedly improve the prediction of postsurgical survival and adjuvant chemotherapeutic benefits. Methods: 125 GC patients were enrolled as a training cohort to detect the expression of 27 immune features using immunohistochemistry and then constructed a five-feature-based ISGC using the LASSO Cox regression model. Internal validation cohort (126 specimens) and two external validation cohorts (628 specimens) were utilized to validate the prognostic and predictive value of ISGC. Results: We established the ISGC classifier based on the five features: CD3invasive margin (IM), CD3center of tumor (CT), CD8IM, CD45ROCT, and CD66bIM. The ISGC classifier could distinguish GC patients with high-ISGC from those with low-ISGC with significant differences in 5-year disease-free survival (45.0% v.s. 4.4%, p < 0.001) and 5-year overall survival (48.8% v.s. 6.7%, p < 0.001). According to the multivariate analysis, the ISGC classifier was proved to be an independent prognostic factor. A combination of ISGC and TNM had better prognostic value than TNM stage alone. In a further analysis, stage II and III GC patients with high-ISGC exhibited a favorable response to adjuvant chemotherapy. To provide a quantitative method to predict stage II and III GC patients’ probability of 3- and 5-year overall survival, we constructed two nomograms that integrated the ISGC and clinicopathological risk factors. Calibration plots showed that the nomograms performed well compared with an ideal model. The predictive accuracy and clinical usefulness of the nomograms were also demonstrated. Conclusions: The ISGC classifier could effectively predict recurrence and survival of GC, and complemented the prognostic value to TNM system. Moreover, the classifier might be a useful predictive tool to identify candidates with stage II and III GC who would benefit from adjuvant chemotherapy. Therefore, the ISGC might facilitate the counseling and personalize the postoperative management of GC patients.

Authors: Zhu Yingming , Yu Jinming , Li Minghuan 
Published: September 2018

e15602 Background: We assessed the prognostic signi cance of, and the relationship between, the pretreatment lymphocyte- to-monocyte ratio (LMR) and the TILs/tumor-associated macrophages (TAMs) ratio, in patients with esophageal squamous cell carcinoma (ESCC) of pathological stage T3N0M0 (pT3N0M0). Methods: A total of 220 newly diagnosed ESCC patients of stage pT3N0M0 who had not undergone neoadjuvant therapy were included. Densities of CD8+ TILs, CD4+ TILs, CD45RO+ TILs, and CD68+ TAMs were assessed by immunohistochemical staining of tissue microarray cores from all 220 pT3N0M0 ESCC patients (who underwent radical resection). Hematological biomarkers including lymphocyte and monocyte counts were obtained from routine preoperative blood test data, and the LMR and TILs/ TAMs ratios calculated. Cutoff nder for survival predic- tion was plotted to nd out the optimal cutoff point for each parameter. Results: The LMR and TILs/TAMs ratios were interrelated. On univariate analyses of data from the entire cohort, the LMR, CD45RO/CD68 ratio, and CD8/CD68 ratio were significantly associated with both OS and disease-free survival. Only the CD45RO/CD68 ratio was independently prognostic of survival on multivariate analysis. Conclusions: The prognostic significance of the CD45RO/ CD68 ratio was higher than that of the LMR. The CD45RO/ CD68 ratio is a useful independent prognostic marker in patients with pT3N0M0 ESCC who have undergone complete resection without neoadjuvant therapy.

e15604 Background: Although, fluoropyrimidine (FP) and taxane based platinum doublet (TP) chemotherapy have demonstrated efficacy against advanced gastroesophageal cancer, these two regimens have not been compared in prospective trials. We retrospectively compared fluoropyrimidine based (FP)and taxane based platinum doublet (TP)chemotherapy in the frontline setting in patients with mGEAC. Methods: Patients with mGEAC treated at Karmanos Cancer Institute between 2000-2014 were reviewed. We compared progression free survival (PFS), Response rate (RR), and toxicity profile of the two regimens. Outcomes were analyzed using weighted estimates. Fisher’s exact tests and Kruskal-Wallis tests were used for categorical and continuous variables, respectively. Survival differences were assessed by a log-rank test. Results: Of the total136 patients, 39% (53) received FP and 61% (83) received TP chemotherapy. Males were 68% (94) of the patients. Gastric, esophageal and gastroesophageal adenocarcinomas contributed to 47% (64), 26.5% (36) and 26.5% (36) of the cases respectively. FOLFOX was the main regimen in FP (62%), followed by 5FU cisplatin (38%). Carboplatin paclitaxel was the main regimen in the TP group. There was no statistically significant difference between the FP and TP arms in terms of PFS, RR, and median OS. The estimated median PFS was 6.39 (95% CI, 5.54-11.15) for the FP group vs 6.92 months (95% CI, 6.13-9.02) for the TP group, (p = 0.90). Objective response rate was (48% for FP group Vs 56% for TP group, p = 0.70). There was more significant grade 4-5 toxicity in FP vs TP based regimen (79 % vs 55 % respectively, p = 0.004). Conclusions: The efficacy of fluoropyrimidine platinum doublet chemotherapy appears to be as comparable to taxane based platinum doublet in the frontline treatment of mGEC. However, the fluorpyrimidine based regimen appears to have more toxicity. Consideration of treatment adverse effects ought to be a key factor in determining the choice of either regimen in mGEAC.

e15607 Background: Preclinical studies have shown synergy between everolimus, an mTOR inhibitor, radiation and platinum agents in EC. We conducted a multi-institutional phase IB trial to determine the recommended phase II dose (RP2D) of concurrent everolimus with carboplatin and radiation in non-metastatic EC pts. Methods: Patients with untreated, localized EC and ECOG performance status 0-1 were eligible. Following two cycles of induction Capecitabine/Oxaliplatin (XELOX), pts without evidence of disease progression, received concurrent chemoradiation (total dose: 50.4Gy in 28 fractions), weekly carboplatin (AUC = 2), and escalating doses of everolimus. A standard 3+3 dose escalation design was used. Results: Nineteen patients were enrolled. There were two screen failures (thrombocytopenia, metastases) and 4 pts were removed due to poor tolerance of XELOX (2 pts) or disease progression (2 pts). A total of 13 pts with stage II/III (6/7) EC completed concurrent therapy. Median age 58 (44-71yrs), 85% males; all had adenocarcinoma deemed resectable. One pt at dose level 1 (2.5 mg/QOD), was replaced due to ongoing anxiety. One of 6 pts had a DLT (bowel ischemia). At dose level 2 (2.5mg/QD), 2 out of 6 patients had a DLT (fever with neutropenia and nausea). The RP2D of everolimus was 2.5 mg QOD. Clinically relevant ≥ grade 3 toxicities included lymphopenia (25%), dehydration (12%), fatigue, leukopenia, hyponatremia, abdominal pain, vomiting (each 6%). R0 resection was achieved in 100%; a pathologic response rate (RR) of 40% and a pathologic complete response (pCR) rate of 23% were observed. The 2-year PFS and OS were 50% and 49.6% respectively. Conclusions: The RP2D of everolimus with concurrent weekly carboplatin and radiation is 2.5 mg QOD. Despite the 100% R0 resection rate, the pCR and OS rates were within the expected historical controls. (The study was funded by Novartis Pharmaceuticals) Clinical trial information: NCT01490749.

Published: September 2018

e15618 Background: In Mexico there is scarce information about oncological outcomes of biliary tract carcinomas (BTC). Methods: we retrospectively reviewed medical records from 150 patients with histologically confirmed BTC (excluding gallbladder cancer) treated in our institution from January 2005 to December 2015.Clinical and pathological information was recorded. Survival was estimated by Kaplan Meir method and compared by Log rank test. Results: we found 63.3% women and 36.7% men, with a median age of 62 years (23 - 88). Tumor localization was intrahepatic in 34.7%, hilar in 43.3% and distal in 22%. Clinical stage was advanced in 71%, regional in 13% and local in 16%. Diagnostic delay was 3.7 months (0.37 - 32.9). For patients with localized disease (which included local and regional disease, n=43), a potentially curative surgery was attempted in 64% (n=27), achieving a R0 resection in 59% (n=16) of cases. There was a 3.9 months (0.83-29.63) treatment initiation delay. There were 7 surgical deaths. For advanced disease (n=107), treatment initiation delay was 4.2 months (0.5 - 34.5), 59% (n=63) of patients did not received oncological active treatment, and 26% (n=28) of patients received a systemic palliative chemotherapy, more frequently gemcitabine (n=20). At progression just eleven patients received a second chemotherapy line. In localized disease resected patients by univariate analysis high levels of CA 19.9 (p=0.04) and CEA (0.03) were associated with decreased survival. For patients with advanced disease prognostic factors included poorly differentiated histology (p=0.04), high bilirrubin level (p=0.04), low albumin level (p=0.001), abscense of chemotherapy (p=0.000) and high CEA levels (p=0.03). Conclusions: Survival is poor in this Mexican cohort of patients with BTC possibly related to diagnostic and therapeutic delay and advanced disease at presentation. [Table: see text]
