Abstract

Objective: Lymphovascular invasion (LVI) has been reported as a predictor of prognosis in multiple cancers. The aim of this meta-analysis was to investigate the potential value of LVI as a prognostic predictor of oral squamous cell carcinoma (OSCC).

Study design: To identify relevant studies, PubMed, Embase, Web of Science, and Cochrane Library database were searched from inception to October 2020. All studies exploring the association of LVI with overall survival (OS), disease-specific survival (DSS), or disease-free survival (DFS) and lymph node metastasis (LNM) were identified.

Result: Pooled odds ratios for LNM and hazard ratios for survival were calculated using fixed effects or random effects models. Thirty-six studies involving 17,109 patients with OSCC were included and further analyzed. The results showed that positive LVI was significantly associated with LNM and worse survival in patients with OSCC. Moreover, positive LVI was correlated with LNM in patients with early stage OSCC.

Conclusions: These findings indicate that LVI may serve as a prognostic predictor for the metastasis and prognosis of OSCC and could be considered a routine pathologic examination in clinical work.
