Background: Oral squamous cell carcinoma (OSCC) is one of the most common malignancies and is a serious problem worldwide. The role of HPV in oral cavity squamous cell carcinoma has been studied in several researches. This present review and meta-analysis aimed to investigate the relation between human papillomavirus (HPV) and oral cancer.
Methods: Relevant studies were found using online international databases including Science direct, Web of science (ISI), PubMed, Scopus, Embase, and Google scholar, to determine relevant studies published between 2000 and Jan 2020. Suitable studies were selected and assessed by two independent researchers. The quality of all papers were determined by a checklist. Heterogeneity assay among the primary studies was evaluated by Cochran's Q test and I2 index. The statistical analyses were done using Stata SE, V.11 software. Trim and Fill method was applied to confirm the validity of the results.
Results: This meta-analysis consists of 8 primary studies on the incidence of HPV infection in Iranian patients with oral diseases. The odds ratio between HPV infection and risk of oral cancer was 4.00 (95%CI: 2.31, 6.93).
Conclusion: This meta-analysis showed associations between prevalence of HPV infection and oral cancer among Iranian patients. The chance of developing oral cancer among HPV positive patients was higher than that in HPV negative patients.
Keywords: Human papillomavirus; Iran; Oral cancer.
