C08.0), tonsil (ICD-O: C09), oropharynx (ICD-O: C10), nasopharynx (ICD-O: C11), pyriform sinus (ICD-O: C12), hypopharynx (ICD-O: C13) and other ill-defined part of the lip, mouth and pharynx (ICD-O: C14). The cancer stage denotes the clinical extent of disease at the time of presentation. It consists of three categories- localised, regional and distant. c) Risk factors: It includes history of personal habits like smoking (cigarettes and bidi), alcohol and smokeless tobacco products like chewable tobacco, pan masala, gutka etc. d) Treatment modality: type of cancer treatment - chemotherapy, radiotherapy and/or surgery was analysed. The data on palliative care was also collected. The data were free from personal identifiers and the patient confidentiality was ensured. The collected data were entered in Microsoft Excel and analysed using Statistical Package for Social Sciences (SPSS) version 23. Data were collected as categorical variables and results are displayed as proportions and tables, pie- charts and graphs were used to demonstrate the results. III. R esults A total number of 441 LOCP cancer cases were reported in our hospital during our study period, from January 1, 2017 to December 31, 2017. In the same period, there were 1992 cases of all types of cancer (978 in men and 1014 in women). LOCP cancers comprised about 22.14% of all cancers registered in the study period. Demographic details: Table–1 shows the sociodemographic characteristics of the study population. Among the 441 study subjects, 329 (74.6%) patients were male and 112 (25.4%) were female. Our study population is distributed from the age of 20 to 93 years with a mean age being 58.25±11.4 years. The age group of 51-60 was found to have the highest percentage of cancer cases (142, 32.2%), followed by the age group of 61-70 years (132, 29.9%). As per the socio-economic status by the Modified Kuppuswamy scale, majority of them belonged either to lower (200, 45.4%) or upper lower class (213, 48.3%). The maximum number of cases came from the Coimbatore district (265, 60.1%), followed by Tiruppur (80, 18.1%) and Erode (47, 10.7%) districts respectively. Clinical profile: Figure-1 shows the subtypes of the LOCP cancers. The most common subtype among LOCP cancers is Mouth (27%), followed by tongue (25%). Histopathologically, squamous cell carcinoma is the most common type contributing to 425 (96.5%) of cases. Figure – 2 shows the stage of cancer at the time of presentation. Nearly 73% of cancer cases presented with regional extent of disease. Localised and regional extent contributed to nearly 84% of cases.
