Abstract Background In recent years, numerous investigations have been conducted to determine the clinical significance and critical functions of vascular endothelial growth factor (VEGF) in various malignant cancers. The purpose of this meta-analysis was to comprehensively evaluate the prognostic and clinicopathological value of VEGF in patients with osteosarcoma. Methods We performed a systematic literature retrieval of available databases. Odds ratios (ORs) or standard mean difference (SMD) for clinicopathological parameters, hazard ratios (HRs) for overall survival and disease-free survival were calculated to assess the correlation between VEGF expression and prognosis in patients with osteosarcoma. Results A total of 22 studies with 1144 patients were included in our study. Pooled analyses showed that VEGF overexpression predicted worse overall survival (HR, 2.42; 95% CI, 1.87–3.11, p < 0.001) and disease-free survival (HR, 2.604; 95% CI, 1.698–3.995, p < 0.001), respectively. Furthermore, investigation regarding osteosarcoma clinicopathologic characteristics suggested that high VEGF expression was significantly associated with metastasis (OR, 4.39; 95% CI, 2.77–6.95; p < 0.001), clinical stage (OR, 0.73; 95% CI, 0.62–0.87; p < 0.001), and microvessel density (SMD, 3.33, 95% CI,1.57–5.10, p < 0.001), but not associated with tumor location, gender, age, local recurrence, and chemotherapy response. Conclusion Our meta-analysis findings suggest that elevated VEGF expression may be a predictive biomarker for poor prognosis and adverse clinicopathological characteristics in patients with osteosarcoma.

AbstractObjective:This study assessed the relationship between vascular endothelial growth factor expression and the laryngeal cancer prognosis.Methods:Systematic computerised searches of PubMed were performed up to 31 January 2015. Prognostic endpoints were overall survival and disease-free survival. The pooled hazard ratios for overall survival and disease-free survival were also calculated.Results:Seven studies containing 975 patients were included. The pooled hazard ratio was 1.703 (95 per cent confidence interval, 1.373 to 2.112; z score = 4.85, p = 0.000) for overall survival and was 1.918 (95 per cent confidence interval, 1.410 to 2.609; z score = 4.15, p = 0.000) for disease-free survival. No significant publication bias was found. A sensitivity analysis showed that the results were robust. Power analyses also showed there was enough power to detect the calculated hazard ratios.Conclusion:The study found that vascular endothelial growth factor overexpression predicted a worse prognosis for laryngeal cancer patients. This supports a strategy of targeted therapy by blocking the vascular endothelial growth factor receptor.

PURPOSE: Vascular Endothelial Growth Factor (VEGF) promotes angiogenesis in many different tumor types. VEGF levels may affect tumor growth, metastatic potential, and response to radiotherapy. This study assesses the prognostic value of VEGF protein levels in a cohort of patients with oral and oropharyngeal squamous cell carcinomas. The relationships between clinical outcome and the covariables of tumor-node-metastasis stage, disease stage (I to IV), grade, margin status, race, sex, and age were also determined. PATIENTS AND METHODS: Chart review identified 77 patients with oral or oropharyngeal squamous cell carcinoma treated with gross total surgical resection and postoperative radiation between 1981 and 1992. Sufficient follow-up data and tumor tissue were available in 56 patients (73%). VEGF protein levels were determined using immunohistochemistry. The association between VEGF status, covariables, and outcome was assessed in a bivariate and multivariate model using two-sided statistical tests. RESULTS: Twenty-three tumors (41%) were positive for VEGF expression. VEGF-positive tumors were more likely to recur locally (relative risk [RR] = 3.08; 95% confidence interval [CI], 1.03 to 9.24) and distantly (RR = 4.62; 95% CI, 1.41 to 15.10). In bivariate analysis, VEGF positivity was the most significant predictor of poor disease-free survival (RR = 2.66; 95% CI, 1.27 to 5.56) and overall survival (RR = 3.21; 95% CI, 1.63 to 6.32). In multivariate analysis, VEGF positivity was the most significant predictor of poor disease-free survival (RR = 2.75; 95% CI, 1.30 to 5.79) and overall survival (RR = 3.53; 95% CI, 1.75 to 7.13). CONCLUSION: In this cohort, VEGF positivity was the most significant predictor of poor prognosis. VEGF status may prove to be an important prognostic factor in head and neck cancer.

Background.Vascular endothelial growth factor (VEGF) and microvessel density (MVD) are associated with greater incidence of metastases and decreased survival. Whether they can be used as prognostic indicators of colorectal cancer (CRC) is still controversial.Methods.The authors performed a meta-analysis using the results of a literature search of databases of PubMed and EMBASE, and the references of articles included in the analysis. Meta-analysis was performed using random effects model and hazard ratios (HRs) and 95% confidence intervals (CIs) as effect measures.Results. Twenty studies contributed to the analysis of VEGF, of which 16 were used for overall survival (OS) and 9 for disease-free survival (DFS). High VEGF levels has a relationship with unfavorable survival (OS: HR = 1.98, 95% CI: 1.30–3.02; DFS: HR = 2.10, 95% CI: 1.26–3.49) and a 4.22-fold increase in the rate of distant metastases. Analysis was performed on 18 studies for MVD; the results showed that patients with high MVD expression in tumors appeared to have poorer overall survival (HR = 1.39, 95% CI: 1.22–1.58) and were at a greater risk of having unfavorable clinical characteristics related to prognosis. Corresponding results were obtained from quantitative and/or qualitative analysis of clinicopathological.Conclusions. The meta-analysis demonstrates that VEGF and MVD can be used as prognostic biomarkers for CRC patients.

Background/Aim. Rectal cancer still presents a major health problem. Although a surgery is the mainstay of the rectal cancer treatment, there is now widespread agreement that combined modality therapy is often indicated. Around 20% of T3N0 rectal cancer patients develop distant or local relapse of the disease. There is a need for prognostic biomarkers that could help us determine the subgroup of patients with a high risk for recurrence. The aim of this study was to determine the prognostic potential of vascular endothelial growth factor (VEGF) in patients with T3N0 rectal carcinoma. Methods. This retrospective study included 163 selected T3N0 rectal cancer patients, operated on the Department for Colorectal Surgery of the Clinic for Digestive Surger (First Surgical Clinic), Clinical Centre of Serbia, Belgrade. VEGF expression was immunohistochemically assessed. Oncological outcome was analyzed using data from prospectively designed data base. Parameters of interest were: distant metastases, the disease free and overall survival. Survival and time to recurrence were evaluated using Kaplan Meier`s method and the factors were compared with the long-rank test. Results. There were 102 men and 61 women. The median age was 62 years (age range, 31?88 years). Median follow-up interval was 81 months (range, 4-177 months). During the follow-up period 6 patients developed local recurrence, in 31 patients distant metastases occurred. Three factors were found to be associated with distant metastases: VEGF expression, mucinous adenocarcinoma and tumor differentiation (p < 0.05). In patients with positive VEGF expression, the disease free survival and overall survival were significantly worse than in negative ones (65% and 59%, respectively) (log-rank test, p < 0.05). Conclusion. High VEGF expression in T3N0 rectal carcinomas together with some standard histopathological tumor features can give us enough information to identify subgroup of patients with high risk for recurrence and poorer prognosis.

50 Background: Nuclear factor-κB (NF-κB) and vascular endothelial growth factor (VEGF) are involved in cell proliferation, invasion, angiogenesis and metastases. The principal objective of this study was to assess the prognostic significance of NF-κB and VEGF expression in gastric cancer Methods: The tumor tissues of 154 patients with gastric cancer, all of whom underwent potentially curative resection, were immunohistochemically evaluated using monoclonal antibodies against NF-κB and VEGF. Results: Positivity rates of NF-κB and VEGF were 44.2% and 39.6%, respectively. NF-κB expression in tumor tissues was correlated significantly with VEGF expression (p < 0.001). VEGF expression was related to Lauren’s classification (p = 0.002), differentiation (p = 0.043), depth of invasion (p = 0.005), carcinoembryonic antigen (p = 0.032), and stage (p = 0.026). However, NF-κB expression was not related to any of these parameters. Univariate analysis demonstrated that NF-κB expression was significantly related with both 5-year disease free survival (65.2% vs. 46.4%, p = 0.007), and 5-year overall survival (60.0% vs. 42.5%, p = 0.014). Multivariate analysis verified that NF-κB was independently associated with disease free survival (hazard ratio: 2.082, p = 0.005), and overall survival (hazard ratio: 1.841, p = 0.008). However, VEGF did not appear to be related to adverse clinical outcome. Conclusions: NF-κB expression in tumor tissue is associated with poor survival in gastric cancer patients.
