Background Although appl1 is overexpressed in many cancers, its status in gastric cancer (gc) is not known. In the present study, we used relevant pathologic and clinical data to investigate appl1 expression in patients with gc.Methods In 47 gc and 27 non-gc surgical specimens, immunohistochemistry was used to detect the expression of appl1, and reverse-transcriptase polymerase chain reaction (rt-pcr) was used to detect messenger rna (mrna). A scatterplot visualized the relationship between survival time and mrna expression in gc patients. The log-rank test and other survival statistics were used to determine the association of appl1 expression with the pathologic features of the cancer and clinical outcomes.Results In gc, appl1 was expressed in 28 of 47 specimens (59.6%), and in non-gc, it was expressed in 7 of 23 specimens (30.4%, p < 0.05). The expression of mrna in gc was 0.82 [95% confidence interval (ci): 0.78 to 0.86], and in non-gc, it was 0.73 (95% ci: 0.69 to 0.77; p < 0.05). Immunohistochemistry demonstrated that, in gc, appl1 expression was correlated with depth of infiltration (p = 0.005), lymph node metastasis (p = 0.017), and TNM stage (p = 0.022), but not with pathologic type (p = 0.41). Testing by rt-pcr demonstrated that, in gc, appl1 mrna expression was correlated with depth of infiltration (p = 0.042), lymph node metastasis (p = 0.031), and TNM stage (p = 0.04), but again, not with pathologic type (p = 0.98). The correlation coefficient between survival time and mrna expression was –0.83 (p < 0.01). Overexpression of appl1 protein (hazard ratio: 3.88; 95% ci: 1.07 to 14.09) and mrna (hazard ratio: 4.23; 95% ci: 3.09 to 15.11) was a risk factor for death in patients with gc.Conclusions Expression of appl1 is increased in gc. Overexpression is prognostic for a lethal outcome.

Lymph node metastasis (LNM) in gastric cancer is associated with higher rate of cancer recurrence and poor prognosis. As a result, a reliable biomarker for the prediction of LNM is important and would be valuable in the clinical practice. MiRNA microarray revealed that ten miRNAs were expressed significantly different among patients with or without LNM. A total of 46 gastric cancer patients were enrolled and divided into two groups (23 in each group) according to the presence or absence of LNM. RT-PCR of these 10 miRNAs was investigated and compared between the two groups. MiR-1207-5p was significantly upregulated in gastric cancer patients without LNM compared with those with LNM. Patients with upregulated miR-1207-5p had less scirrhous stromal reaction, less lymphovascular invasion, and earlier pathological T category, N category, and TNM stage, compared with those with downregulated or unchanged miR-1207-5p. Multivariate analysis showed that stromal reaction type, lymphovascular invasion, pathological T category and TNM stage, and expression of miR-1207-5p were independent risk factors of LNM. MiR-1207-5p could serve as a useful biomarker in the prediction of LNM in gastric cancer.

Abstract Background Many cancer researchers have investigated the prognostic significance of LASP1 for survival of patients with various types of cancer. Nevertheless, the role LASP1 palyed in cancer prognosis remains unknown. In consequence, we carried out this study in order to comprehensively analyze the prognostic value of LASP1 in cancer patients. Methods A systematical research was conducted in electronic databases, such as PubMed, Embase and Web of Science. Eighteen studies meeting the inclusion criteria were enrolled. Overall survival (OS), recurrence-free survival (RFS) and various clinicopathological parameters were used as the endpoints in this study. Results A total of 2023 cancer patients from eighteen studies were finally enrolled into our meta-analysis. The results revealed that the cancer patients with high expression of LASP1 exhibited shorter OS (HR = 2.04, 95%CI = 1.77–2.34, P < 0.01) and RFS (HR = 2.11, 95%CI = 1.51–2.95, P < 0.01) than those with low expression of LASP1, and patients whose tumors expressed high LASP1 had shorter OS in lung cancer (HR = 2.20, 95%CI = 1.45–3.36, P < 0.01) and gastric cancer (HR = 1.64, 95%CI = 1.14–2.36, P < 0.01) respectively. Furthermore, the cancer patients whose tumors expressed high LASP1 were apparently associated with advanced TNM stage (OR = 2.92, 2.27–3.76, P < 0.01), earlier lymph node metastasis (OR = 2.69, 1.62–4.45, P < 0.01), advanced T classification (OR = 2.17, 1.48–3.18, P < 0.01) and earlier distant metastasis (OR = 2.56, 1.03–6.35, P = 0.04) when compared to those whose tumors expressed low LASP1. Conclusions Our study showed that the high LASP1 expression might be an undesirable predictor for patients with various types of cancers in the aspect of OS, RFS, TNM stage, lymph node metastasis, T classification and distant metastasis, and the high LASP1 expression might be an undesirable predictor for lung cancer patients and gastric cancer patients. Therefore, the expression of LASP1 might be utilized as a novel indicator in judging the prognosis of cancer patients, especially in lung cancer and gastric cancer.

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.

54 Background: Tumor associated macrophages (TAMs) are major components of tumor environment, and polarized into M1 and M2 type. M1 has been known as antitumorigenic, whereas M2 as protumorigenic. M2 have a significant role in tumor progression by promoting tumor cell invasion, migration and angiogenesis. We evaluated the M2 macrophages to investigate its importance in predicting clinical outcome or prognosis, and the relationship between M2 and angiogenesis in patients with gastric cancer. Methods: Formalin-fixed, paraffin-embedded blocks were obtained from the 88 patients with gastric cancer. CD163+ TAMs and CD105+ vessels were evaluated by immunohistochemical staining and the extent of CD163+ TAMs in tumor were divided into three groups: (A) infiltrated TAMs in cancer cell nest (nest TAMs); (B) infiltrated TAMs in tumor stroma (stroma TAMs); and (C) infiltrated TAMs along the invasive margin of a tumor (margin TAMs). Results: The increased stroma and margin TAMs (>72 and >102, respectively) were closely correlated with lymph node metastasis, TNM stage and lymphatic invasion (p<0.05 in 3 factors) and positive correlation existed between the stroma and margin TAMs (p<0.001). Disease-free survival rate analyzed using the Kaplan– Meier method was significantly lower in patient with high stroma and margin TMAs than patient with low stroma and margin TAMs (p=0.0039 and 0.0499, respectively). CD105+ vessels showed significant correlation with lymph node metastasis and lymphatic invasion.(p=0.006 and p<0.0001, respectively) Stromal, marginal and nest TAMs were positively correlated with CD105+ vessels (p=0.001). Conclusions: M2 infiltration in tumor stroma and tumor margin in gastric cancer showed relationship with aggressive phenotypes such as lymph node metastasis, TNM stage and lymphatic invasion and was correlated with angiogenesis. This study supports the view that the adverse prognostic impact of M2 involves tumor angiogenesis in gastric cancer.

Abstract Background:The relationship between PROX1 expression and clinicopathological characteristics and prognosis in patients with gastric cancer (GC) is hotly contested and continues to be so. The aim of this study is to determine the clinicopathological and prognostic significance of PROX1 expression in patients with GC.Methods:PROX1 expression in GC patients was evaluated clinicopathologically and in terms of overall survival (OS) using a systematic literature search and meta-analysis. Additionally, the Cancer Genome Atlas (TCGA) and The Genotype-Tissue Expression (GTEx) datasets were utilized to examine the relationship between PROX1 expression and clinicopathological significance and overall survival (OS) in GC patients.Results:A total of 8 studies pooling 1289 GC patients were included in the assessment. PROX1 expression, in GC patients, was shown to be unrelated to gender (odds ratio (OR) : 1.234, 95%CI: 0.958-1.590, P = 0.104), depth of tumor invasion (OR: 0.742, 95%CI:0.428-1.287, P = 0.289), lymph node metastasis (OR: 2.161, 95%CI: 0.808-5.779, P = 0.125), TNM stage (OR: 1.324, 95%CI: 0.572-3.066, P = 0.513), tumor size (OR: 0.889, 95%CI: 0.502-1.576, P = 0.687), metastasis (OR: 1.096, 95%CI: 0.470-2.555, P= 0.763), 1-year OS (OR: 0.908, 95%CI: 0.631-1.306, P = 0.602), 3-years OS (OR: 1.234, 95%CI: 0.482-3.160, P = 0.661) and 5-years OS (OR: 0.853, 95%CI: 0.266-2.736, P = 0.790). Patients with high PROX1 expression had a worse OS than those with low PROX1 expression, according to TCGA analyses, however the difference was not statistically significant (p=0.119).Conclusion:The expression of PROX1 was shown to be unrelated to gender, TNM stage, depth of invasion, tumor size, stage, tumor cell metastasis, or lymph node metastasis. The expression of PROX1 was also unrelated to OS and it failed to be a meaningful biomarker to prevent and diagnose GC.

AbstractLymph node metastasis (LNM), a common metastatic gastric-cancer (GC) route, is closely related to poor prognosis in GC patients. Bone marrow-derived mesenchymal stem cells (BM-MSCs) preferentially engraft at metastatic lesions. Whether BM-MSCs are specifically reprogrammed by LNM-derived GC cells (LNM-GCs) and incorporated into metastatic LN microenvironment to prompt GC malignant progression remains unknown. Herein, we found that LNM-GCs specifically educated BM-MSCs via secretory exosomes. Exosomal Wnt5a was identified as key protein mediating LNM-GCs education of BM-MSCs, which was verified by analysis of serum exosomes collected from GC patients with LNM. Wnt5a-enriched exosomes induced YAP dephosphorylation in BM-MSCs, whereas Wnt5a-deficient exosomes exerted the opposite effect. Inhibition of YAP signaling by verteporfin blocked LNM-GC exosome- and serum exosome-mediated reprogramming in BM-MSCs. Analysis of MSC-like cells obtained from metastatic LN tissues of GC patients (GLN-MSCs) confirmed that BM-MSCs incorporated into metastatic LN microenvironment, and that YAP activation participated in maintaining their tumor-promoting phenotype and function. Collectively, our results show that LNM-GCs specifically educated BM-MSCs via exosomal Wnt5a-elicited activation of YAP signaling. This study provides new insights into the mechanisms of LNM in GC and BM-MSC reprogramming, and will provide potential therapeutic targets and detection indicators for GC patients with LNM.

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.
