Profile of colorectal cancer in Eastern India.

Although colorectal cancer is a major cause of concern in the western population, recent studies are showing the incidence and mortality of colorectal cancer to be rapidly rising in Asia. The present study is an insight into the epidemiological profile of colorectal cancer of a representative Eastern Indian population. Over a period of three years, all histologically proved patients with colorectal cancer were assessed for age, sex, body mass index, dietary habits, socioeconomic status and stage of disease. Of a total of 168 patients male to female ratio was 1.7:1.The mean age of presentation was 47.01 years. Although colorectal cancer has been known as a disease of sedentary obese men, 41.66% of the patients were from a low socioeconomic rural set-up and 40.47% were involved in heavy physical labour with only 15% of being obese; 62% patients were harbouring a locally advanced disease at the time of presentation. The epidemiological pattern of colorectal cancer in India is different from that of the west as regards to earlier age of presentation, prevalence in low socio economic class with low fat diet and scanty meat intake.
