It undertakes re-screening of cases in government hospitals and Cancer Institute (WIA), trace back deathcertificate notifications and collect information on all the deaths, irrespective of the stated cause on the deathcertificate, occurring in the registry area routinely to reduce the under-registration of incident cancer cases andassociated mortality. The completeness of registration during 1982-95 was assessed by conducting an independentsurvey in randomly selected areas in Chennai. The total number of households covered in the survey was 7737 andwere collected which constituted 1% of the Chennai city population. The response rate to the survey was 96%. Atotal of 42,502 incident cancer cases were registered in Chennai PBCR during 1982-95. The total number of cancercases that were already registered in PBCR from the survey area during 1982-95 was 208.

Two newcancer cases hitherto unregistered in the PBCR during 1982-95 were identified from the survey.
