Abstract Background As neoadjuvant chemotherapy (NCT) has been successfully introduced in gastric cancer (GC), more biomarkers are needed to evaluate the efficacy. Cancer-associated fibroblasts (CAFs) is associated with chemoresistance and prognosis. Three biomarkers, CD10, fibroblast activation protein-α (FAP) and G-protein-coupled receptor 77 (GPR77), have been proved to express in CAFs. However, their predictive values for efficacy of NCT and prognosis in gastric cancer is unknown. Methods Totally, specimens of 171 locally advanced gastric cancer patients who underwent NCT and D2 radical gastrectomy and matched preoperative biopsy specimens were retrospectively analyzed. Tumor regression grade (TRG) is reevaluated according to Mandard TRG. Expressions of CD10, FAP and GPR77 in CAFs before NCT (pre-) and after NCT (post-) were evaluated by immunohistochemistry. Survival curves on overall survival (OS) were obtained by Kaplan-Meier method, and differences were analyzed by log-rank test. Associations between categorical variables were explored by chi-square test or Fisher's exact method. Univariable and multivariate analyses were performed by logistic regression model and Cox proportional hazard regression model. Results High expressions of post-CD10, post-FAP, post-GPR77 and pre-CD10 were related to worse TRG (all p<0.05). In multivariable analysis, post- and pre-FAP were independent predictive factors to TRG (p<0.010). Post-CD10 (p=0.032) and post-FAP (p=0.013) were related to OS in univariable analysis, but none of biomarkers were independent prognostic factors in multivariable analysis. Conclusions Expressions of CD10, FAP and GPR77 in CAFs were related to chemoresistance and overall survival, and these biomarkers have predictive values for tumor regression and prognosis in locally advanced gastric cancer patients.

e15535 Background: Preoperative nutritional status in gastric cancer patients is not only correlated with postoperative complications, also, prognostic nutritional index or Onodera´s nutritional index (PNI) may relate with overall survival (OS) after gastrectomy. There is no available data of preoperative nutritional status in Mexican population. We decide to explore these variables and analyze its impact in outcomes reported in our population. Methods: This is a retrospective included a total of 91 patients patients with locally advanced gastric cancer confirmed by laparoscopy treated in the National Cancer Institute in México between January 2010 and June 2016. The PNI level was determined according the following formula: 10 x serum albumin (g/dl) + 0.005 x total lymphocyte count (per mm3). The optimal cutoff value of PNI in our population was set at 38.7 according the median, we stratified patients in high (PNI > 38.7) or low (PNI < 38.7) nutritional status, clinicopathologic features were compared. Results: We analyzed 91 patients, the mean patients age was 58, 61.5% were man, the 51.6% went to total gastrectomy with D2 dissection, 56% were pathologic stage III and 61.5% of the patients received adjuvant chemotherapy. The patients with high nutritional status had a OS of 46 months vs patients with low nutritional status with 25 months (p = 0.009). Patients with body mass index (BMI) > 23 had a OS of 41 months vs patients with BMI < 23 with 19 months of OS (p = 0.001), finally the patients with albumin > 3.75 had a 39 months of OS vs 23 months with albumin < 3.75 (p = 0.011) Conclusions: The low PNI group had worse OS than the high PNI group (46 months vs 25 months, p = 0.009). Preoperative is a simple and useful marker to predict overall survival in patients with locally advanced gastric cancer

4538 Background: Gastric cancer remains the 3rd leading cancer related death worldwide due to early disease recurrence. We hypothesize that hyperthermic intraperitoneal chemotherapy (HIPEC) may effectively prevent local regional recurrence for locally advanced gastric cancer patients who received curative intent surgery. Methods: Pathology proven gastric cancer patients with clinical T3/T4NxM0 disease are eligible for the study and will be randomized to either control group, who will receive standard radical gastrectomy and D2 lymph node dissection or HIPEC group, who will receive the same surgery and HIPEC with paclitaxel x 2 within the first week after surgery. All patients will receive either XELOX or SOX adjuvant chemotherapy. The primary end point is overall survival. Results: 648 patients from 16 high volume gastric medical centers were enrolled between May, 2015 and March, 2019. 331 and 317 patients were randomized to control and HIPEC groups respectively. The median follow-up time is 12.1 months. The common grade 3/4 toxicities ( > 5%) in control and HIPEC groups are anemia 6% vs. 4.1%, intraabdominal infection 5.4% vs. 3.8%, pneumonia 9.7% vs. 9.8%, fever 10.6% vs. 11.4% and hypoalbunemia 15.1% vs. 16.7% respectively. All three perioperative death (within 30 days after surgery) occurred in control group. One patient died from duodenum stump leak which led to multiple organ failure. One patient died from anastomotic led to intraabdominal infection and shock. The 3rd death was suicide caused by severe depression. At the time of this report, the number of event has not reached for final efficacy analysis. Conclusions: It is safe to administer HIPEC to patients received radical gastrectomy with D2 lymph node dissection within one week of surgery. The primary analysis will be expected in one year.
