Incidence of colorectal cancers in India: A review from population-based cancer registries

Abstract

A number of studies on population-based cancer registries (PBCRs) data have been reported from India about various cancers. However, updated status of colorectal cancer is not available in literature. The objective is to provide an overview of age-specific and age-adjusted colorectal cancer incidence reported in 27 PBCRs in India. Secondary data on age-specific and age-adjusted rates of incidence rate, the lifetime risk of the disease was computed using cumulative risk and a number of cases for all ages (0–75 years), were collected from the report of the National Cancer Registry Program 2012-2014 in 27 population-based control registries. The annual incidence rates (AARs) for colon cancer and rectal cancer in men are 5.36 and 5.17/100,000, respectively. The AAR for colon cancer in women is 4.3/100,000. Males were comparably at higher risk than females. The maximum lifetime risk of developing colon cancer ranged from 167 to 500 females and lifetime risk of developing rectum cancer ranged from 100 to 353 in males. The risk of colorectal cancers was high amongst the Northeast population followed by South regions of India. The management of colon and rectal cancer cases and screening could serve to control the disease.
