Smokeless Tobacco Usage and Oral Cancer Risk: A Hospital-Based Case-Control Study From Bangladesh.

ABSTRACT:

Objectives

Smokeless tobacco (SLT) use is common in South Asia and strongly associated with oral cancer. In Bangladesh, where SLT use is widespread, evidence remains limited. This study examined the association between SLT use and oral cancer among Bangladeshi adults and estimated the population-level burden.

Methods

This first hospital-based case-control study from Bangladesh examined the association between SLT use and oral cancer. Conducted in Dhaka between July and December 2015. A total of 169 newly diagnosed oral cancer cases and 338 frequency-matched controls were recruited.
