title: The association of smoking, alcoholic consumption, betel quid chewing and oral cavity cancer: a cohort study.
abstract: We aimed to analyze the relationship between smoking, alcoholic consumption and betel quid chewing with oral cavity cancer. All male patients age > or =18 years who visited our clinic received an oral mucosal inspection. Basic data including personal habits were also obtained. A multivariate logistic regression model was utilized to determine relevant risk factors for developing oral cavity cancer. A total of 8,356 patients were enrolled in this study. Abnormal findings were found in 382 patients (4.6%). Two hundred and ninety-seven patients received biopsy and 191 patients were proven to have oral cavity cancer. The results of multivariate logistic regression showed that those who smoked, consumed alcohol and chewed betel quid on a regular basis were most likely to contract oral cancer (odds ratio: 39.66, 95% confidence interval: 26.04-60.38). Therefore, habitual cigarette smokers, alcohol consumers, and betel quid chewers have a higher risk of contracting oral cavity cancer and should receive oral mucosal screening regularly so potential oral cavity cancer can be detected as early as possible, which may result in better and improved survival of oral cancer patients.
