Abstract

Oral cancer is one of the most common life threatening diseases in Asian countries. Smoking, smokeless tobacco and alcohol are considered to be the most potent risk factor for oral cancer. This study was conducted to investigate the association of smokeless tobacco with oral cancer. A case-control study of 350 cases and 350 controls over a period of 19 months during February 2005 and September 2006 was carried out in Pune, India. The self-reported information about the consumption of smokeless tobacco, alcohol, dietary habits and demographic status was collected by structured questionnaires. Univariate and multivariate analysis was used to identify the risk of substances abuse. The frequency of smokeless tobacco in cases were significantly higher than controls (P < 0.0001). Among smokeless types, consumption of gutkha (P < 0.0001, OR = 12.8, 95% CI =7.0-23.7), chewing tobacco (P < 0.0001, OR = 8.3, 95% CI = 5.4-13.0), supari (P < 0.0001, OR = 6.6, 95% CI =3.0-14.8), mishiri (P < 0.0001, OR = 3.3, 95% CI =2.1-5.4), indicated strong association with oral cancer upon adjustment. Smokeless products were more frequent than smoking among individuals with oral cancer. Of smokeless type; gutkha, supar, i chewing tobacco and mishiri emerged significant in oral cancer development.
