Genes involved in metastasis in oral squamous cell carcinoma: A systematic review

Abstract

Background and AimsOral squamous cell carcinoma is the most prevalent malignancy in the oral cavity, with a significant mortality rate. In oral squamous cell carcinoma patients, the survival rate could decrease because of delayed diagnosis. Thus, prevention, early diagnosis, and appropriate treatment can effectively increase the survival rate in patients. In this systematic review, we discussed the role of different genes in oral squamous cell carcinoma metastasis. Herein, we aimed to summarize clinical results, regarding the potential genes that promote oral squamous cell carcinoma metastasis.MethodsThis systematic review was carried out under the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines. An electronic search for all relevant articles published in English between January 2018 and April 2022 was performed using Scopus, PubMed, and Google Scholar search engines. All original studies published in English were included, and we excluded studies that were in a non‐English language.ResultsA total of 4682 articles were found, of which 14 were relevant and detected significant genes in oral squamous cell carcinoma progression. These findings investigated the overexpression of interferon‐induced proteins with tetratricopeptide repeats 1 and 3 (IFIT1, IFT3), high‐mobility group A2 (HMGA2), transformed growth factor‐beta‐induced, lectin galactoside‐binding soluble 3 binding protein (LGALS3BP), bromodomain containing 4, COP9 signaling complex 6, heterogeneous nuclear ribonucleoproteins A2B1 (HNRNPA2B1), 5′−3′ exoribonuclease 2 (XRN2), cystatin‐A (CSTA), fibroblast growth factors 8 (FGF8), forkhead box P3, cadherin‐3, also known as P‐cadherin and Wnt family member 5A, ubiquitin‐specific‐processing protease 7, and retinoic acid receptor responder protein 2 genes lead to promote metastasis in oral squamous cell carcinoma. Overexpression of some genes (IFIT1, 3, LGALS3BP, HMGA2, HNRNPA2B1, XRN2, CSTA, and FGF8) was proven to be correlated with poor survival rates in oral squamous cell carcinoma patients.ConclusionStudies suggest that metastatic genes indicate a poor prognosis for oral squamous cell carcinoma patients. Detecting these metastatic genes in oral squamous cell carcinoma patients may be of predictive value and can also facilitate assessing oral squamous cell carcinoma development and its response to treatment.
