Abstract:
BACKGROUND:Vasculogenic mimicry (VM) is the formation of vascular channels by tumor cells or tumor cell-derived, trans-differentiated cells in highly aggressive, solid tumors. However, the disease features and prognostic value of VM for overall survival of cancer patients remain controversial. METHOD:To systematically investigate the roles of VM in cancer progression and its prognostic values, we performed a meta-analysis based on 36 studies (33 eligible articles) including 3609 patients. The pooled hazard ratios (HRs) with 95 % confidence intervals (95 % CIs) were used to assess the relationship between VM and overall survival in cancer patients. RESULTS:Vasculogenic mimicry was significantly associated with cancer differentiation, lymph node metastasis, distant metastasis, and TNM stage. The prognostic value of VM was significant in overall survival (HR 2.16; 95 % CI 1.98-2.38; P < 0.001). Analyses stratified by confounders, such as cancer type, ethnicity, VM detection methods, sample size, and Newcastle-Ottawa quality score, found similar significant results. CONCLUSIONS:The presence of VM predicts poorer survival outcomes in cancer patients.
