Prevalence of oral squamous cell carcinoma in Bareilly Region: A seven year institutional study.

Background: Oral squamous cell carcinoma is a major contributor to disability and death caused by malignant tumors. Variations in social, cultural, and geographic factors affect the tumor behavior and response to treatment. In this study, we undertake a seven years institutional review and analysis of Oral squamous cell carcinoma cases in Bareilly.

Materials and methods: A total of 1938 histologically diagnosed cases during the period of seven years i.e. from 2010 to 2016 were extracted from the archives of Department of Oral & Maxillofacial Pathology, Institute of Dental Sciences, Bareilly and evaluated to know the prevalence of Oral squamous cell carcinoma. The details like age, sex, habits and anatomical site were also recorded from the archived patient's case sheets.

Results: Out of the total 1938 cases, 318 were found to be Oral squamous cell carcinoma of which 232 were males and 86 were females. Incidence was highest in 40-49 year age group. The most common site was buccal mucosa (190 cases), followed by tongue (68 cases). Most lesions were well differentiated Oral squamous cell carcinoma (230 cases). Patients with poorly differentiated lesions had a comparatively lower mean age than their counterparts with other histological varieties.

Conclusion: The pattern of Oral squamous cell carcinoma differs from that of previous studies in relation to incidence and age correlation with the grade of carcinoma. The majority of the lesions were well differentiated. There is a need for intensive oral health awareness to encourage early presentation to cancer center as early detection will further enhance prognosis.
