ARTICLE HIGHLIGHTS
Research background
Several clinical and histopathologic factors have been investigated as prognostic indicators of survival in patients with gastrointestinal stromal tumours (GISTs).
Research motivation
Microvessel density (MVD) has been extensively applied as a direct method of tumour vascularity assessment.
Research objectives
This meta-analysis attempted to estimate the pooled effect of tumoral vascularity based on MVD assessment on the survival of patients with GISTs.
Research methods
The present meta-analysis adhered to the Systematic reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions.
Research results
Low vascularized tumours were associated with improved pooled disease-free survival. GISTs with lower MVD values displayed a reduced risk of metastases.
Research conclusions
MVD is significantly associated with the survival outcomes of GIST patients.
Research perspectives
Further prospective randomized controlled trials are required to delineate the exact correlation between MVD and prognosis outcomes in GIST patients.
