Purpose. This study is aimed at evaluating the clinicopathological features and prognostic significance of gastric outlet obstruction (GOO) in patients with distal gastric cancer. Methods. A retrospective review of 1564 individuals with distal gastric cancer from 2002 to 2010 was performed. In total, 157 patients had GOO. The clinicopathological features of the patients with GOO were compared with those of the patients without GOO. A Kaplan-Meier survival analysis and Cox proportional hazard model were used to assess the overall survival. Results. The patients with distal gastric cancer with GOO generally presented more aggressive pathologic features, a poorer nutritional status, more duodenal infiltration, and peritoneal dissemination than those with cancer without GOO. In the univariate analysis, curability, GOO, age, prealbumin, albumin, hemoglobin (Hb), the tumor size, the macroscopic type, lymph node metastasis, and the depth of invasion had a statistically significant influence on prognosis. The multivariate analysis showed that curability, GOO, the tumor size, lymph node metastasis, and the depth of invasion were independent prognostic factors. Conclusions. Gastric cancer with GOO exhibits aggressive biological features and has poor outcomes. The multivariate analysis showed that curability, GOO, the tumor size, lymph node metastasis, and the depth of invasion were independent prognostic factors. The gastric outlet status should be considered in the selection of surgical treatment methods for patients with gastric cancer.

Abstract Background Since the definition of early gastric cancer (EGC) was first proposed in 1971, the treatment of gastric cancer with or without lymph node metastasis (LNM) has changed a lot. The present study aims to identify risk factors for LNM and prognosis, and to further evaluate the indications for adjuvant chemotherapy (AC) in T1N + M0 gastric cancer. Methods A total of 1291 patients with T1N + M0 gastric cancer were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate analyses were performed to identify risk factors for LNM. The effect of LNM on overall survival (OS) and cancer-specific survival (CSS) was compared with patients grouped into T1N0-1 and T1N2-3, as the indications for AC. Results The rate of LNM was 19.52%. Multivariate analyses showed age, tumor size, invasion depth, and type of differentiation and retrieved LNs were associated with LNM (p < 0.05). Cox multivariate analyses indicated age, sex, tumor size, N stage were independent predictors of OS and CSS (p < 0.05), while race was indicator for OS (HR 0.866; 95%CI 0.750–0.999, p = 0.049), but not for CSS (HR 0.878; 95% CI 0.723–1.065, p = 0.187). In addition, survival analysis showed the proportion of patients in N+/N0 was better distributed than N0-1/N2-3b. There were statistically significant differences in OS and CSS between patients with and without chemotherapy in pT1N1M0 patients (p༜0.05). Conclusions Both tumor size and invasion depth are associated with LNM and prognosis. LNM is an important predictor of prognosis. pT1N + M0 may be appropriate candidates for AC. Currently, the treatment and prognosis of T1N0M0/T1N + M0 are completely different. An updated definition of EGC, taking into tumor size, invasion depth and LNM, may be more appropriate in an era of precision medicine.

e16547 Background: It is reported that hyperfibrinogenemia is commonly seen in gastric cancer. This study aim to discuss the association between fibrinogen level and preoperative clinicopathological factors and to evaluate the value as a predictor of prognosis. Methods: Retrospectively reviewed the medical records and follow-up data of patients with gastric cancer who underwent curative resection from January 2011 to December 2014 at Surgery Department of the Fourth Hospital of Hebei Medical University. Fibrinogen was measured a week before the surgery. Results: A total of 248 cases were enrolled. The means±SD of fibrinogen was 3.28±1.06g/L. Fibrinogen level was higher in older adults(≥60y), advanced tumor, poorly differentiated, deep invasion, lymph node metastasis, large tumor size and in those with high CEA, platelet count, albumin, NLR and PLR,( P< 0.05). All the people were divided by the TNM staging system and found that the plasma fibrinogen was higher in stageⅡand Ⅲ (stageⅠvs. stageⅡ: 2.84±0.72g/L vs. 3.36±1.18g/L, P= 0.009;stageⅠvs. stage Ⅲ: 2.84±0.72g/L vs. 3.43±1.07g/L, P< 0.001), however, there was no difference between stageⅡand Ⅲ( P= 0.662)(our study did not enrolled stage IV patients).When patients were classified into 4 groups according to the T classification, the plasma fibrinogen level gradually increased with increasing depth of cancer invasion (one way ANOVA; P= 0.002). Yet, when the patients who have lymph nodes metastasis classified according to the N classification, the differences among them did not have statistically significance ( P= 0.333). Multivariate analysis revealed that hyperfibrinogenemia had an independent association with advanced cancer (odds ratio,2.686(1.012-7.125); P= 0.047), lymph node metastasis (odds ratio,2.012 (1.012-3.125); P= 0.035) and tumor size(odds ratio,1.949 (1.099-3.454); P= 0.022). Our study aslo suggested that the patients with hyperfibrinogenemia before surgery showed a significantly lower survival rate (Log-Rank test; P< 0.001), hyperfibrinogenemia was a independent predictor on the overall survival, which could predict worse clinical outcome. Conclusions: Hyperfibrinogenemia may be considered a useful biomarker to predict advanced tumor, lymph node metastasis and large tumor size and can be a good predictor of worse clinical outcome.

Background: It is challenging to identify the prevalence of lymph node metastasis (LNM) and residual tumor in patients with early gastric cancer (EGC) who underwent noncurative endoscopic resection (ER). This present meta-analysis was aimed to establish imperative potential predictive factors in order to select the optimal treatment method. Methods: A systematic literature search of PubMed, Embase, and Cochrane Library databases was performed through 1 February 2019 to identify relevant studies, which investigated risk factors for LNM and residual tumor in patients with EGC who underwent noncurative ER. Eligible data were systematically reviewed through a meta-analysis. Results: Overall, 12 studies investigating the risk factor of LNM were included, totaling 3015 patients, 7 of which also involved cancer residues. After the present meta-analysis, six predictors, including tumor size >30 mm, tumor invasion depth (⩾500 μm from the muscularis mucosae), macroscopic appearance, undifferentiated histopathological type, positive vertical margin, and presence of lymphovascular invasion (including lymphatic invasion and vascular invasion) were significantly associated with LNM, whereas tumor size >30 mm, positive horizontal margin, and positive vertical margin were identified as significant predictors for the risk of residual tumor. No evidence of publication bias was observed. Conclusions: Six and three variables were established as significant risk factors for LNM and residual tumor in patients with EGC who underwent noncurative ER, respectively. Patients with EGC who present these risk factors after noncurative ER are strongly suggested to receive additional surgery, while others might be suitable for strict follow-up. This might shed some new light on the selection of follow-up treatment for noncurative ER.

Abstract Background It remains controversial whether splenic hilum lymph nodes (SHLNs) should be excised in radical gastrectomy with D2 lymph node dissection. In this study, we evaluated the role of clinicopathological features in patients with gastric cancer in predicting splenic hilum lymph nodes metastasis.Methods We searched the Medline, Embase, PubMed and Web of Science databases from inception to May 2020 and consulted related references. 15 articles with a total of 4377 patients were included finally. The odds ratios (ORs) of each risk factor and the corresponding 95% confidence interval (CI) were determined using Revman 5.3 software. Results Meta-analysis showed that tumor size greater than 5 cm (p < 0.01), tumor localization in the greater curvature (p < 0.01), diffuse type (Lauren’s type) (p < 0.01), Borrman type 3–4 (p < 0.01), poor differentiation and undifferentiation (p < 0.01), depth of invasion T3–T4 (p < 0.01), number of lymph node metastases N2–N3 (p < 0.01), distance metastasis M1 (p < 0.01), TNM stage 3–4 (p < 0.01), vascular invasion (p = 0.01), and lymphatic invasion (p < 0.01) were risk factors of SHLNs metastasis. Moreover, No. 1-, 2-, 3-, 4sa-, 4sb-, 4d-, 6-, 7-, 9-, 11-, and 16-positive lymph node metastasis are strongly associated with splenic hilum lymph nodes metastasis.Conclusions Tumor size, tumor location, Lauren’s type, Borrman type, degree of differentiation, T stage, N stage, M stage, TNM stage, vascular invasion, lymphatic infiltration, and other positive lymph nodes metastasis were risk factors for SHLNs.

Abstract Background: Despite the decline in the incidence of gastric cancer, the incidence of early gastric cancer has increased. Hence, understanding the clinicopathological and prognostic features of early gastric cancers could help us understand the development of gastric cancer and improve the prognosis of early gastric cancer. Methods: A total of 244 patients diagnosed with early gastric cancer after surgery at Xiangya Hospital Central South University were retrospectively analyzed. Results: General data showed that in patients with a mean age of 54.30±10.68 years (M:F = 1.6:1), the median tumor size was 2.203±1.245 cm. A total of 15.6% of patients had lymph node metastasis. By univariate analysis, the longest diameter of the tumor, T stage, total number of dissected lymph nodes, number of metastatic lymph nodes, metastatic-to-total dissected lymph node (LN) ratio, vascular invasion, NLRc, and MLRc were associated with disease-free survival; tumor size, invasive depths, vascular invasion, NLRc, MLRc, NWRc and LWRc were associated with lymph node metastasis. Additionally, the longest diameter of tumor and total number of dissected lymph nodes were independent factors for early gastric cancer patients; tumor size, invasive depths, vascular invasion and NLRc were independent risk factors for lymph node metastasis in EGC. Conclusion: The longest diameter of the tumor and total number of dissected LNs were independent prognostic factors for EGC patients. Additionally, the longest diameter of the tumor, tumor invasive depths, vascular invasion and NLRc were the independent risk factors for lymph node metastasis in EGC patients.

84 Background: Use of perioperative chemotherapy (CTx) alone versus chemo-radiation therapy (cXRT) in the treatment of resectable gastric cancer remains varied. We sought to define the utilization and effect of CTx alone versus cXRT on patients having undergone curative-intent resection for gastric cancer. Methods: Using the multi-institutional U.S. Gastric Cancer Collaborative database, we identified 505 patients between 2000 and 2012 with gastric cancer who received perioperative therapy in addition to curative-intent resection. The impact of perioperative therapy on survival was analyzed by the use of propensity-score matching of clinicopathologic factors among patients who received CTx alone versus cXRT. Results: Median patient age was 62 years and the majority of patients were male (58%). Surgical resection involved either partial gastrectomy (54%) or total gastrectomy (46%). On pathology, median tumor size was 5.0 cm; most patients had a T3 (37%) or T4 (36%) lesion and lymph node metastasis (74%). Margin status was R0 in most patients (89%). 211 (42%) patients received perioperative CTx alone whereas the remaining 294 (58%) patients received 5-FU based cXRT. Factors associated with receipt of cXRT were younger age (OR 0.98), T3 tumors (OR 1.52), and lymph node metastasis (OR 2.03) (all P < .05). Recurrence occurred in 214 (39%) patients. At a median follow-up of 28 months, median overall survival (OS) was 33.4 months and 5-year survival was 36.7%. Factors associated with worse OS included tumor size (HR 1.1), T-stage (HR 1.5), and lymph node metastasis (HR 1.58) (all P<0.05). In contrast, receipt of cXRT was associated with improved long-term OS (CTx alone: 21 months vs. cXRT 45 months; p<0.001). In the propensity-matched multivariate model that adjusted for tumor size, T-stage, and nodal status, cXRT remained associated with an improved long-term disease-free (HR 0.43) and overall (HR 0.41) survival (both P<0.001). Conclusions: XRT was utilized in 58% of patients undergoing curative-intent resection for gastric cancer. Using propensity-matched analysis, cXRT was an independent factor associated with improved recurrence-free and overall survival.

Abstract Objective This study analyzed the characteristics of early gastric cancer lymph node metastasis and survival prognosis after surgical resection in western population, and established a predictive model.MethodsPatients with stage T1a and T1b gastric cancer from 2010 to 2015 were screened from the surveillance, epidemiology and final outcome databases. Patients with multiple in situ tumors, distant metastases, and incomplete data were excluded. The risk factors for lymph node metastasis in early gastric cancer were analyzed by binary logistic regression and the chi-square test. Multivariate Cox analysis and the Kaplan-Meier test were used to evaluate the prognostic factors and survival rates of patients with early gastric cancer after surgical resection. The prediction model of lymph node metastasis and survival rate of early gastric cancer was established and verified by R software.ResultsIn 2294 patients, the lymph node metastasis rate was 14.5% (333/2294). Binary logistic multivariate regression analysis showed that tumor size (>2cm), tumor grade (III/IV), and stage T1b were risk factors for lymph node metastasis of early gastric cancer. Area under the curve (AUC) is 0.782.A predictive model was developed based on risk factors, and the model C index was 0.771, indicating that the model has good predictive ability. In addition, survival analysis of 2294 patients showed that the 5-year OS and CSS (75.4% and 88.7%) in patients without EGC were significantly higher than those with lymph node metastasis (64.3% and 72.8%) (P<0.05). Multivariate COX analysis showed that age, sex, race, tumor size, submucosal invasion and lymph node metastasis were independent factors influencing the prognosis of early gastric cancer. A cancer-specific survival (CSS) prediction model was constructed based on prognostic risk factors. The 3-year area under the CSS curve (AUC) was 0.706, and the 5-year area under the CSS curve (AUC) was 0.710. The prediction model is more consistent with the actual situation.ConclusionsWe established a reliable prediction model for lymph node metastasis of early gastric cancer and a prognostic model for early gastric cancer, which provided a good basis for clinical treatment decision.

Background. Neuropilin 1 (NRP1) is involved in tumorigenesis, development, invasion, and metastasis by promoting angiogenesis of tumors. The study is aimed at evaluating the correlation between the expression of NRP1 protein and clinicopathological features of gastric cancer by meta-analysis. Methods. The published studies were searched in databases including CNKI, Wanfang, Chongqing VIP, Web of Science, and PubMed online. Clinical case studies were included to compare the correlation between NRP1 protein expression and clinicopathological characteristics of gastric cancer. The quality of the included literatures was evaluated by NOS scale. Meta-analysis was performed by Stata software to calculate the odds ratio (OR) and 95% confidence interval (CI). Results. A total of 12 studies were included in this analysis, involving 1,225 patients with gastric cancer. The analysis indicated that the expression of NRP1 protein in gastric cancer tissues was lower in the group of early stage versus advanced stage (OR=0.128, 95%CI=0.059−0.277, P≤0.001), tumor size less than 5 cm versus more than 5 cm (OR=0.443, 95%CI=0.310−0.632, P≤0.001), TNM stage I-II group versus stage III-IV patients (OR=0.736, 95%CI=0.589−0.919, P=0.007), well to medium differentiation group versus poor differentiation group (OR=0.735, 95%CI=0.632−0.854, P≤0.001), and nonlymph node metastasis group versus lymph node metastasis group (OR=0.667, 95%CI=0.522−0.854, P≤0.001). The expression of NRP1 protein in gastric cancer was not related to gender, age, and Laurèn’s classification. Conclusion. The expression of NRP1 protein in gastric cancer is closely correlated to clinical stage, tumor size, TNM stage, differentiation, and lymph node metastasis.
