Abstract
ObjectiveOral potentially malignant disorders (OPMDs) are oral mucosal conditions that may progress to oral squamous cell carcinoma (OSCC). Although autoimmunity has linked to the malignant transformation potential of various precancerous conditions, its role in OPMD remains unclear. This review aimed to identify the role of systemic autoimmunity on OPMD development and their progression to OSCC. MethodsA comprehensive literature search was conducted using PubMed, Cochrane CENTRAL, and SCOPUS database for articles published up to January 2024. The key questions addressed by this review were “Is autoimmunity associated with the development of OPMD” and “How does systemic autoimmunity influence the potential for malignant transformation of OPMD?”. This review followed the PRISMA guidelines for scoping reviews (PRISMA-ScR). ResultsOf the 1265 articles initially identified, 21 fulfilled the search criteria. Three themes were emerged; 1) the prevalence and prognosis of oral cancers in patients with systemic autoimmune diseases, 2) circulating autoantibodies in OPMD patients, and 3) autoimmune-related markers linked to malignant transformation in OPMD patients. This review indicated that systemic autoimmunity may contribute to chronic inflammatory conditions, disruption of oral mucosal integrity, and interference with the DNA damage repair process, thus influencing malignant transformation in the oral epithelium of patients with OPMD. ConclusionThe co-occurrence of OPMD with circulating autoantibodies or systemic autoimmune diseases underscores the importance of understanding these interactions for improved management of OPMD and early detection of OSCC.
