Methods: A cross-sectional descriptive study was conducted to assess the tobacco use pattern, its frequency and type. Individual oral examination was done by a single examiner to check the premalignant lesions and oral cancer among tea plantation workers, Nilgiri Hills. Data was collected using a pretested Questionnaire, which included Demographic data, tobacco habits, its frequency and form. The data collected was analysed using SPSS version15.Results: showed that among 400 study population from 5 tea estates, 46% had no formal education and 65% had indigenous brushing habits. 52% of oral mucosal lesions were detected, out of which most commonest was leukoplakia 34%, 42% tobacco pouch keratosis and 6% malignant oral tumours. Prevalence of oral mucosal lesions in the study population was due to tobacco usage and lack of awareness regarding the deleterious effects of the products used.Conclusions: Tobacco use is a major preventable cause of premature deaths and diseases, the dangers from smoking and chewing tobacco are well documented within the literature but the public's lack of knowledge of the risks is a concern. Health professionals are encouraged to ensure that the public is made aware of these risks.

consistently shown to correlate with survival in clinical studies. NAR score is a composite endpoint combining clinical and pathological staging information obtained before and after NCRT which warrants validation in local population. The main objective of this study is to investigate the factors that may influence the achievement of ypCR, such as age, sex, tumour stage and location, presence of threatened CRM and extramural vascular invasion (EMVI) as well as tumour down-staging. Other objectives are to validate the prognostic significance of NAR score and to investigate any factors that are associated with a lower score.
