Different tumour grading in smokeless tobacco (Naswar) user and non-user in squamous cell carcinoma.
Objectives: To determine the relationship of Naswar with different tumour grading in squamous cell carcinoma. Study Design: Comparative cross-sectional study using non-probability, consecutive sampling. Setting: Department of Oral Pathology, Rehman College of Dentistry, Peshawar, Khyber Pakhtunkhwa, Pakistan. Period: January 2017 till June 2017. Material & Methods: 60 cases of oral squamous cell carcinoma were included. Half the cases (30) had a history of Naswar use while the other half (30) had no history of Naswar use. Data was analysed using SPSS v 22. Results: This study included 60% male and 40% female cases, ranging from 40 years to 80 years (mean = 57.6 + 11 years). Majority of patients 80% had well differentiated squamous cell carcinoma, while the rest (20%) had poorly differentiated. Distribution of male and female across both groups was equal (p 0.598). Both the groups were comparable in terms of grade of tumour (p 0.519). Conclusion: Naswar use was not associated with any particular histological grade of oral squamous cell carcinoma in our study. However, further research is needed to explore this association.
