The prevalence of oral squamous cell carcinoma with oral submucous fibrosis.

OBJECTIVE: The objective of the study was to find out the prevalence of oral squamous cell carcinoma (OSCC) with oral submucous fibrosis (OSF) in patients with OSF. MATERIALS AND METHODS: Of 48,757 patients, we found 300 OSF subjects. Three hundred patients of OSF were checked for OSCC. Both OSF and OSCC with OSF (OSCCwOSF) were diagnosed histopathologically. The prevalence of OSCCwOSF was calculated. Descriptive analysis was done. Chi-square test and t-test were calculated for proportions and mean, respectively, to check any difference among OSF and OSCCwOSF groups. Age-specific relative risk was calculated in OSF and OSCCwOSF groups. Multiple logistic regression analysis was done among odd ratios of the different variable between OSF and OSCCwOSF groups. RESULTS: The prevalence of OSCCwOSF among OSF was 13.7% over a period of 1 year. The mean age of OSCCwOSF group was 43.95 +/- 10.22 years in comparison to the OSF group that was 35.51 +/- 11.26 years (P < 0.00). The mean habit duration was significantly less in the OSF group when compared to OSCCwOSFgroup for mishri (P = 0.002). Age-specific adjusted relative risk of OSCC in OSF patient increases from 0.33 (18-34 years) to 3.86 (>/=65 years). CONCLUSION: It could be concluded that a 13.7% prevalence rate of OSCCwOSF in OSF patients should alert the clinician. Clinicians should, therefore, anticipate OSSC in OSF patients. This awareness could lead to the early diagnosis and management of such OSCC.
