Background <p>Autophagy is involved in several critical cellular processes regulating cell survival and death. Past research suggests that it may either act as a tumor suppressor or promote tumor progression. The purpose of this systematic review and meta-analysis was to evaluate the clinical and prognostic utility of a significant autophagy related protein—Beclin1, in oral squamous cell carcinoma (OSCC).</p> Methods <p>Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were followed. Relevant literature was retrieved from PubMed, ScienceDirect and Google Scholar database. After removal of duplicates quality of the studies was assessed using Newcastle–Ottawa Scale. Heterogeneity was assessed using I² index. Random effect model was used if I² was more than 50% else fixed effect model was selected. Meta-analysis was carried out using Review Manager (RevMan; Version 5.4).</p> Results <p>Five studies with 494 cases were included in this meta-analysis. Beclin1 expression in OSCC was not significantly associated (p &gt; 0.05) with gender, age, tumor size, lymph node metastasis, histological differentiation and overall survival. Nevertheless, a trend for low Beclin1 expression favoring tumor progression was observed. Sensitivity analysis revealed significant nodal positivity related to low Beclin1 expression.</p> Conclusion <p>This study provided an overview of Beclin1 expression in OSCC and highlighted additional evaluations while its use as a prognostic marker. It is suggested that future studies should assess both nuclear as well as cytoplasmic expression of Beclin1 and report intra- and inter-tumor variations in its expression relating to clinicopathological parameters.</p>
