Prognostic Value of Microvessel Density in Head and Neck Squamous Cell Carcinoma: A Meta-Analysis

الملخص EN

The prognostic value of microvessel density (MVD) in head and neck squamous cell carcinoma (HNSCC) remains disputable.

The purpose of this study was to comprehensively determine the prognostic value of MVD in HNSCC.

Relevant literatures were identified using PubMed, Embase, and Cochrane Library.

A meta-analysis was performed to clarify the prognostic role of MVD in HNSCC patients and different subgroups.

A total of 14 eligible articles were included in this meta-analysis.

The combined hazard ratio (HR) and 95% confidence interval (95% CI) for overall survival (OS) of 11 studies was 1.663 (1.236-2.237, P=0.001), and the pooled HR and 95% CI for progression-free survival (PFS) of 7 studies was 2.069 (1.281-3.343, P=0.003).

Subgroup analyses were also performed on different issues, such as regional distribution of patients, age, tumor location, antibody, and treatment strategy.

To conclude, high MVD is associated with worse OS and PFS in patients with HNSCC.
