Abstract
OBJECTIVE: We conducted the present meta-analysis with relevant cohort studies to determine whether expression levels of vascular endothelial growth factor. (VEGF) could predict the prognosis of diffuse large B.cell lymphoma. (DLBCL).
MATERIALS AND METHODS: The MEDLINE (1966-2013), the Cochrane Library Database (Issue 12, 2013), EMBASE (1980-2013), CINAHL (1982--2013), Web of Science (1945-2013), and the Chinese Biomedical Database (1982-2013) were searched without any language restrictions. Meta-analysis was conducted using STATA software (Version 12.0, Stata Corporation, College Station, Texas USA). Hazard ratios (HR) and their corresponding 95% confidence intervals (95% CI) were calculated.
RESULTS: Eight clinical cohort studies, which recruited a total 670 DLBCL patients, were included in the meta-analysis. The results of this meta-analysis indicate that DLBCL patients with positive VEGF expression had a shorter overall survival than those with negative VEGF expression. (HR = 1.58, 95% CI = 0.80-2.36, P < 0.001). Ethnicity-stratified analysis illustrates that high expression levels of VEGF may be significantly correlated with poor DLBCL prognosis among both Caucasian and Asian populations. (Caucasian: HR = 1.73, 95% CI = 0.56-2.90, P = 0.004; Asian: HR = 1.45, 95% CI = 0.41-2.50, P = 0.006).
CONCLUSION: The major findings of our meta-analysis reveal that the aberrant expression of VEGF may correspond to shorter overall survival of patients with DLBCL, revealing that VEGF expression could be an unbiased prognostic determinant in the management of DLBCL patients.
