Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant disease, but the genetic basis of PDAC is still unclear. In this study, Nectin-2 and DDX3 expression in 106 PDAC, 35 peritumoral tissues, 55 benign pancreatic lesions, and 13 normal pancreatic tissues were measured by immunohistochemical methods. Results showed that the percentage of positive Nectin-2 and DDX3 expression was significantly higher in PDAC tumors than in peritumoral tissues, benign pancreatic tissues, and normal pancreatic tissues (P<0.01). The percentage of cases with positive Nectin-2 and DDX3 expression was significantly lower in PDAC patients without lymph node metastasis and invasion and having TNM stage I/II disease than in patients with lymph node metastasis, invasion, and TNM stage III/IV disease (P<0.05orP<0.01). Positive DDX3 expression is associated with poor differentiation of PDAC. Kaplan-Meier survival analysis showed that positive Nectin-2 and DDX3 expression were significantly associated with survival in PDAC patients (P<0.001). Cox multivariate analysis revealed that positive Nectin-2 and DDX3 expression were independent poor prognosis factors in PDAC patients. In conclusion, positive Nectin-2 and DDX3 expression are associated with the progression and poor prognosis in PDAC patients.

Background. Gastric cancer (GC) is an important malignant disease around the world. Abnormalities of microRNAs (miRNAs) have been implicated in carcinogenesis of various cancers. In the present study, we examined miR-21 expression in human gastric cancer with lymph node metastasis and attempted to uncover its relationship with clinicopathologic data, especially with lymph node metastasis.Materials and Methods. The expression levels of miR-21 in the tumor specimens of GC patients were quantified by RT-PCR. The correlation between miR-21 level and multiple clinicopathological factors was then examined by Mann-Whitney test, Kaplan-Meier survival analysis, and operating characteristic (ROC) analysis.Results. The expression level of miR-21 was higher in GC patients with lymph node metastasis than in those without lymph node metastasis (P<0.05). Expression level of miR-21 was significantly correlated with histologic type, T stage, lymph node metastasis and pTNM stage. The overall survival rates in GC patients with low upregulated miR-21 expression were significantly higher than those with high upregulated miR-21 (P<0.05).Conclusion. A close association is implicated between the elevated miR-21and lymph node metastasis, which could potentially be exploited as a practical biomarker for lymph node metastasis in patients with GC.

Rab27b is reported to associate with the development and progression of several types of human cancers. However, the relationship between Rab27b expression and the clinical characteristics of lung adenocarcinoma (LUAD) is rarely explored. In this present study, the TCGA database was consulted, followed by one-step quantitative reverse transcription polymerase chain reaction (qPCR), Western blot, and immunohistochemistry (IHC) analyses in LUAD cell lines and tissue samples. Rab27b expression levels were statistically higher in LUAD cell lines and tissue samples compared with a noncancerous cell line and tissue samples (p<0.05). Rab27b expression was statistically correlated with lymph node metastasis (p=0.016) and TNM stage (p=0.019). Survival analysis and Kaplan-Meier curve revealed that Rab27b expression (p=0.006) and TNM stage (p=0.027) were independently associated with the unfavorable overall survival of patients with LUAD. These results indicate that high expression of Rab27b correlates with malignant attributes of LUAD and Rab27b may be identified as a potential indicator of metastasis and prognosis for LUAD.

Abstract Background: To explore significance of CA19-9, D-dimer with TNFAIP3 (A20) protein and evaluate its prognostic significance in patients suffering from pancreatic ductal adenocarcinoma (PDAC). Methods: 148 patients suffering from pancreatic ductal adenocarcinoma in Northern Jiangsu People’s Hospital affiliated to Yangzhou University between January 2012 to December 2016 were studied. Cutoff values of prognostic factors were predicted by Receiver operating characteristic curve (ROC curve). Kaplan-Meier method was used to describe survival curve of patients. Univariate and multivariate regression analyses were used to analyze prognostic factors of patients. Results: The recommended cutoff values of the neutrophil-lymphocyte rate (NLR), platelet-lymphocyte rate (PLR), CA19-9 and D-dimer were 2.04 (sensitivity, 0.59; specificity, 0.9; area under the ROC curve (AUC), 0.749; P<0.001), 52.94 (sensitivity, 0.73; specificity, 0.95; AUC, 0.829; P<0.001), 176.66U/ml (sensitivity, 0.7; specificity, 0.9; AUC, 0.794; P<0.001) and 1.18mg/L (sensitivity, 0.82; specificity, 0.9; AUC, 0.845; P<0.001) respectively. The expression of CA19-9 in serum was related with lymph node metastasis (P = 0.010), tumor lymph node metastasis (TNM) stage (P <0.001) and survival ratio (P <0.001). The D-dimer was positively related with differentiation grade (P=0.014), tumor size (P=0.045), TNM stage (P=0.006) and survival ratio (P<0.001). A20 was positively related with differentiation grade (P<0.001), BMI (P<0.001), TNM stage (P=0.024) and survival ratio (P<0.001). The Kaplan-Meier curves showed that the patients with pancreatic ductal adenocarcinoma had a significant difference in the expression of CA19-9 group, expression of D-dimer group and expression of A20 (P<0.05). CA19-9, D-dimer, TNM stage, differentiation grade and A20 were independent prognostic markers for patients sufferingfrom pancreatic ductal adenocarcinoma by univariate and COX multivariate analyses. Conclusions: CA19-9, D-dimer and A20 were independent prognostic markers for pancreatic ductal adenocarcinoma patients.

Background: Nrf2 pathway and autophagy are abnormally activated in response to cellular stress in various types of human cancers. In this study, we selected Beclin1 as an enter point to discuss the relationship between Nrf2 pathway and autophagy, and defined their associations with clinic pathological features and survival of the patients. Method: NSCLC specimens were processed for immunohistochemical and qRT-PCR to analyses the expression of Beclin1 and Nrf2. Kaplan-Meier method and log-rank test were used in the survival data. Results: Beclin1 protein level was found to be significantly associated with more advanced TNM stage (P = 0.035), lymph node metastasis (P = 0.017) and distant metastasis (P = 0.005). The expression of Nrf2 protein was associated with larger tumor size (P = 0.032), more advanced TNM stage (P = 0.011), lymph node metastasis (P = 0.045) and distant metastasis (P = 0.013). Beside there was a strong inverse relationship between Beclin1 and Nrf2 expression in the NSCLC tissues. Distant metastasis, Beclin1, Nrf2, and Beclin1-/Nrf2+ expression was conformed to be independent prognostic factors of patients. Conclusion: Both Nrf2 overexpression and Beclin1 lower-expression are independent indicators of a poor prognosis in NSCLC patients.

Abstract Background: Breast cancer is one of the most common cancers among females with high morbidity and mortality. MicroRNAs (miRNAs) have been reported to play important roles in the development of cancers. However, the prognostic value of microRNA-421 (miR-421) in breast cancer have not been extensively explored.Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the relative expression of miR-421 in breast cancer tissue samples. Relationships between miR-421 expression and clinicopathological factors were analyzed by chi-square test. The effects of several variables on survival status were tested by Kaplan-Meier curve and Cox proportional hazards regression analyses.Results: MiR-421 expression was significantly decreased in breast cancer tissues, compared with adjacent noncancerous tissues (P<0.001). Moreover, abnormal miR-421 expression was closely correlated with lymph node metastasis (P<0.001), TNM stage (P=0.021), and differentiation (P=0.044) of breast cancer patients. Kaplan-Meier analysis revealed that patients with low miR-421 expression had a shorter overall survival time than those with high miR-421 expression (P=0.001). Furthermore, multivariate analysis demonstrated that miR-421 (P=0.014, HR=2.000, 95%CI: 1.149-3.480) was an independent prognostic indicator in breast cancer patients, as well as lymph node metastasis (P=0.016, HR=1.987, 95%CI: 1.137-3.474).Conclusion: The reduced expression of miR-421 may predict the poor prognosis of breast cancer and miR-421 may be involved in the progression of breast cancer.

BACKGROUND and OBJECTIVE: Gastric adenocarcinoma (GAC) is one of the most common malignancies. Increasing data have indicated a correlation between soluble B7-H3 (sB7-H3) levels and tumor malignancies. In this study, we aim to investigate the level of soluble B7-H3 in serum of GAC patients. Further, we analyze the correlation between sB7-H3 level and tissue B7-H3 expression and explore the clinical evaluation value of sB7-H3 associated with pathological characteristics and prognosis of GAC patients. METHODS: One hundred and twenty-eight serum and tissue samples of GAC 20 serum and tissue samples of gastritis patients and 77 serum, 5 tissue samples of healthy controls were collected. The serum levels of sB7-H3 were detected by Enzyme-linked immunosorbent assay (ELISA), while the expression of membrane B7-H3 (mB7-H3) and Ki67 were evaluated by immunohistochemistry. The correlation between sB7-H3 and mB7-H3, sB7-H3 and Ki67, sB7-H3 or mB7-H3 and clinical features were analyzed by Pearson’s Chi-square test. RESULTS: Both serum level of sB7-H3 and tissue B7-H3 of GAC patients were significantly higher than those of gastritis patients and healthy controls. sB7-H3 level was correlated with total B7-H3 expression in tissues (r= 0.2801, P= 0.0014). Notably, the concentration of sB7-H3 was correlated with its expression of membrane form in tumor cells (r= 0.3251, P= 0.002) while not in stromal cells (r= 0.07676, P= 0.3891). Moreover, the levels of sB7-H3 in patients with TNM stage III/IV or with Infiltration depth T3/T4 or with lymph node metastasis were significantly higher than those of patients with TNM stage I/II (P= 0.0020) or with Infiltration depth T1/T2 (P= 0.0169) or with no lymph node metastasis (P= 0.0086). Tumor B7-H3 score, but not stromal B7-H3 score, in patients with TNM stage III/IV or with lymph node metastasis was significantly higher than those with TNM stage I/II (P= 0.0150) or with no lymph node metastasis (P= 0.182). CONCLUSIONS: Soluble B7-H3 level may reflect the tissue B7-H3 expression on tumor cells of GAC tissues. Elevated level of sB7-H3 in serum suggests poor clinical pathological characteristics of GAC patients.
