Objective To explore the association of c-erbB-2 protein expression with clinicopathological characteristics and prognosis of gastric cancer (GC) after surgery. Methods A total of 133 patients undergoing surgical resection for GC between March 2006 and January 2009 in the Second Affiliated Hospital of Wenzhou Medical University were included in this study. c-erbB-2 protein expression was determined by immunohistochemistry. Afterwards, a meta-analysis was performed to further confirm the association between c-erbB-2 protein expression and GC by employing stringent inclusion and exclusion criteria. All data analyses were conducted with STATA 12.0 and SPSS 19.0. Results There was no significant difference in c-erbB-2 expression among patients with various parameters including age, gender and histological types (all p>0.05). Among 133 GC patients, 32 patients presented c-erbB-2-positive expression and 101 presented c-erbB-2-negative expression (24.1% vs. 75.9%). The c-erbB-2-positive expression rate was significantly higher in GC tissues of patients with lymph node metastasis than those without. Similarly, a significant increase in c-erbB-2 expression was observed in well/moderately differentiated GC tissues compared with poorly differentiated GC. Patients with negative c-erbB-2 expression had a higher 5-year survival rate than those with positive c-erbB-2 expression, which was consistent with the results of the meta-analysis (OR = 0.54, 95% CI 0.37-0.80, p = 0.002). Conclusions Our study demonstrated that high expression of c-erbB-2 protein was strongly associated with lymph node metastasis, histological differentiation and 5-year survival rate in GC patients after surgery.

ObjectiveThis study aimed to assess the relationship between BRCA1 gene methylation, PD-L1 protein expression, and the clinicopathologic features of sporadic ovarian cancer (OC).MethodsBisulfite pyrosequencing and immunohistochemistry were used to detect BRCA1 gene methylation and PD-L1 protein expression, respectively, in tumor tissues from 112 patients with sporadic OC. Their levels were analyzed against clinicopathologic characteristics and prognosis using standard statistical methods.ResultsTwenty percent (22/112) of the OC cases exhibited BRCA1 gene hypermethylation. The frequency of BRCA1 hypermethylation was significantly higher in serous OC (25%) than in nonserous OC (8%; P < 0.05). No significant correlations were discovered between BRCA1 hypermethylation and age, menstrual status, tumor location, stage, lymph node metastasis, and prognosis (P > 0.05). Among the 112 OC cases, 59% (66/112) cases were positive for PD-L1 protein expression. No significant difference existed between PD-L1 expression and age, menstrual status, histological type, tumor location, stage, lymph node metastasis, and prognosis (P > 0.05). Moreover, no correlation existed between BRCA1 methylation and PD-L1 expression (P > 0.05, r = 0.002).ConclusionsThis is the first study linking BRCA1 hypermethylation variability to PD-L1 protein expression and the clinicopathologic features of OC. The data demonstrated that an epigenetic alteration of BRCA1 was closely associated with serous OC. The expression of PD-L1 was unrelated to the clinicopathologic features or BRCA1 hypermethylation in sporadic OC.

Abstract Background: It is well established that retrieved lymph nodes (RLNs) count were positively correlated with better overall survival in gastric cancer (GC). But little is known about the relationship between RLNs count and short-term complications after radical surgery. Methods: A total of 1487 consecutive GC patients between January 2016 and December 2018 at Nanjing Drum Tower Hospital were retrospectively analyzed. Univariate analyses were performed to elucidate the association between RLNs count and postoperative complications. We further identified clinical factors that might affect the RLNs count.Results: Among all of the patients, postoperative complications occurred in 435 (29.3%) patients. The mean RLNs count was 25.1 and 864 (58.1%) patients were diagnosed with lymph node metastasis. Univariate analyses showed no significant difference between RLNs count and postoperative complications (both overall and stratified by CDC grade). We further explored that preoperative serum albumin, type of resection, operation time, tumor invasion, lymph node metastasis, and pTNM stage were associated with RLNs count. Conclusions: The current study demonstrated that RLNs count was not associated with postoperative short-term complications following gastrectomy of GC, which provided a rationale for the determination of a proper RLNs count of curative gastrectomy.

161 Background: Optimal treatment strategy for patients with liver metastasis from gastric cancer (LMGC) has not yet been established. Although systemic chemotherapy remains mainstay of treatment for LMGC, complete resection of primary tumor and LMGC may improve survival outcome. Thus, the aim of this study is to investigate survival outcome and prognostic factors of patients who underwent hepatic resection for LMGC. Methods: From September 2002 to February 2014, 30 patients underwent hepatic resection for LMGC in our hospital. Indications of hepatic resection were as follows; (1) hepatic lesion is not more than three, (2) without extrahepatic metastasis other than lymph node metastasis, (3) adequate liver function. We investigated the overall median survival time (MST) and 5-year survival rate of all eligible patients. Univariate and multivariate analyses were performed to assess the association between each clinicopathological features and overall survival time. Results: There were 25 males and 5 females with a median age of 72 (range, 39-86). There were 16 synchronous LMGCs and 14 metachronous LMGCs. With respect to the number of LMGC, 22 patients had 1 lesion, 7 patients had 2 lesions, and 1 patient had 3 lesions. Overall MST and 5 year survival rates after hepatic resection were 2.8 years and 31.0%, respectively. The significant prognostic factors were age (70 years or older, p=0.029) and blood transfusion (p=0.013). Multivariate analysis showed that lymph node metastasis was an only independent indicator of poor prognosis (HR=6.13, p=0.026). Conclusions: Hepatic resection for patients with LMGC might be a promising treatment strategy, with 5-year survival rate of 31.0%. Lymph node metastasis was an only independent prognostic factor. A multi-institutional confirmatory study will be required to evaluate the role of hepatic resection in patients with LMGC.
