BACKGROUND: In the Indian scenario, a large percentage of tobacco abuse is in the form of Smokeless tobacco (ST) and the usage pattern has undergone a gradual change over the years with chewers becoming lesscommon. Hence, there is a need to reassess the epidemiology of oral cancer with respect to these recent tobacco product usage. AIM OF THE STUDY: This study aims to find the usage pattern of non-smoking tobacco in patients with oral cancer in comparison with people without cancer. MATERIALS AND METHODS: 100 cases of established oral cancer patients with history of quid use were compared with 100 age matched controls with quid use but no cancer. Both were administered semi-structured questionnaires and data analysed with SPSS. RESULTS: The most common age group affected by cancer was 46-55 yrs. (35%), mean age of presentation was 51.5 years and 31% presented with cancer at age <45 yrs. The mean years of exposure for tobacco quids placed in mouth was 20.85 with significantly more quids use number, overnight usage pattern (69%) and placement for more than 1 hour/ usage (38%) among cases than controls. Other abuses like bidi (52%), cigarette (47%), alcohol (53%) and other types of smokeless tobacco (54%) were significantly more than in controls. Awareness of ill effects was lesser (53%) and abstinence was more in cases (54%) than in controls. CONCLUSION: The study has found that a person who has oral cancer and primarily uses tobacco quids tends to use it more frequently, for longer periods of time than controls and is more likely to consume alcohol, cigarettes and bidis on a regular basis. The disfigurement and loss of function caused by oral cancer, its treatment, the number of life years lost due to the disease and the ever growing incidence of Oral squamous carcinoma in our country point to the fact that we need to emphasise on increasing public awareness, screening, early diagnosis and treatment.
