Correlation Between Clinical and Histopathological Stagings of Oral Submucous Fibrosis: A Clinicopathological Cognizance of 238 Cases From South India.

Abstract

Background This paper aims to descriptively present the clinico-demographic and pathological profile of 238 cases of oral submucous fibrosis (OSMF) with emphasis on the correlation between clinical and histopathological classification systems and the incidence of malignant transformation. Methods A total of 7098 oral biopsies were retrospectively retrieved over a period of 13 years, out of which 238 cases of OSMF were included in the present study. Data were analyzed for age, gender, habits, clinical symptoms, functional staging, histological staging, type and nature of epithelium, signet-ring cell changes, presence/absence of dysplasia or transformation squamous cell carcinoma, and treatment. Results Clinically and histologically, most cases were moderately advanced. Men outnumbered women. The prevalence of dysplasia was found to be 23.94% and the malignant transformation rate was estimated to be 13.8%. There was a significant correlation between clinical staging with age and histological grading. No correlation was found between histological staging and the age of the patients. Conclusions OSMF is a habit-related progressive chronic oral condition with a high malignant transformation rate. Multimodal treatment with auxiliary physiotherapy helps in the improvement of the clinical symptoms.
