Oral cancer screening at workplace in India-one-year follow-up

Abstract

Background:Oral cancer remains the commonest form of cancer and cancer-related deaths among Indian males due to popularity of avoidable risk factors such as tobacco and alcohol use. A workplace oral cancer screening and tobacco cessation study was commenced on World No Tobacco Day 2007 at a chemical industry in rural Maharashtra.Aims:The objectives were to screen the employees for oral neoplasia and to correlate it with their tobacco consumption pattern. In addition, the objective was to provide tobacco cessation services at the workplace.Materials and Methods:This is an interventional cohort study among 104 employees of a chemical industrial unit in rural Maharashtra. Naked eye examination of the oral cavity was performed for all employees by a doctor irrespective of the tobacco habits at the beginning and at the end of 1 year. In between, the tobacco users were regularly examined during each follow-up.Statistical analysis used:Through personal interviews of the participants, data were manually recorded and were transferred to electronic data base. Data analysis was conducted in STATA™ 8.2 on intention to treat basis.Results and Conclusions:Among the 104 employees, 50 (48.08%) were current tobacco users at the beginning of the program. Oral precancers were seen exclusively among 20 (40%) tobacco users. After 1 year of workplace tobacco cessation intervention, 80% of oral precancers regressed. This shows that screening of the oral cavity at the workplace is effective when combined with tobacco cessation.

High Level of Estrogen in Male Oral Cancer Patients and Consumption of Smokeless Tobacco

“…Almost similar finding has been seen in India as well as in different parts of the world (Murthy et al, 2011;Petit, 2003). Smokeless form of tobacco use was predominant, and majority of the oral precancers were detected in employees using the smokeless form in a recent study (Uplap, et al, 2011) In the present study, out of 126 oral cancer patients, 101 male and 25 female oral cancer patients were found. Figure 1 shows that prevalence of oral cancer in male patients.…”

Mortality from oral cancer in Aracaju/SE, Brazil: 2000-2009

“…According to the World Health Organization (WHO), oral cancer is responsible for 267,000 new cancer cases, of which approximately two-thirds originate from developing countries 1,5,6 . In these countries, oral cancer is the third most common type of cancer, second only to cervical and stomach cancer 7 .…”

A receiver operated curve-based evaluation of change in sensitivity and specificity of cotinine urinalysis for detecting active tobacco use

“…After 1 year of workplace tobacco cessation intervention, 80% of oral precancers had regressed. [12] Socially undesirable behaviors such as tobacco use are prone to underreporting. [43,44] Trends of underestimation have been reported when smoking prevalence is based on self-report alone.…”

“…[1] Tobacco use, smoking as well as smokeless forms, is associated with increased risk of carcinoma in various Indian studies. [6][7][8][9][10][11][12] Rates of tobacco use, specially smoking rates, are on the rise in low-and middle-income countries. [13] Of greater concern if the fact that by 2030 more than 80% of the world's tobacco-related deaths will be in low-and middle-income countries including India.…”
