- Abstract
Objective: To explore the correlations between the habit of betel quid and areca nut (BQ‐AN) chewing and the prognosis of oral cancer (OC). Methods: We performed a systematic review and meta‐analysis to clarify this issue. Data searches were performed using PubMed, Web of Science, Epistemonikos, and Embase databases through November 2019. The primary outcome was the difference in the prognosis of OC between BQ‐AN chewers and non‐chewers, measured in terms of 5‐year overall survival (OS) and 5‐year disease‐specific survival (DSS) log (HR) reported in articles. The pooled HR with 95% CI of 5‐year OS and 5‐year DSS was calculated using a fixed‐effects model. Results: Ten articles with eleven OS or DSS survival studies (one of the articles contained two studies), which were published between 2003 and 2017, were eligible for inclusion in the present study. All the 11 studies were observational studies, among which 10 were retrospective and 1 was prospective. One study measured both OS and DSS. Eight studies, with a total of 2,761 patients, used 5‐year OS as the primary endpoint and four studies, with a total of 2,551 patients, used 5‐year DSS. Overall, the pooled HR evaluating BQ‐AN chewers was 1.26 (95% CI: 1.09–1.46) for 5‐year OS and 1.40 (95% CI: 1.15–1.70) for 5‐year DSS, compared with non‐chewers. There was a significant association between BQ‐AN chewing and OC survival. Conclusions: Betel quid and areca nut chewing is significantly associated with poor prognosis in patients with OC.
