title: [Relationship of proportion of DCO cases in cancer registration to gastric cancer screening participation rate and proportion of all referred inpatients diagnosed with neoplasm].
abstract: Of all cancer cases registered the proportion where identification is solely from death certificates, (DCO-Death Certificate Only), is one of the important indices for assessing the accuracy of the cancer registration system. Regional differences exist in the proportion comprised of DCO cases. These differences were analyzed in terms of the regional differences that also exist in gastric cancer screening participation rates, proportion of all referred inpatients with diagnoses of neoplasm by place of residence, and proportion of all referred inpatients with diagnoses of neoplasm by place of treatment. Up to 65% of the regional differences in DCO proportion can be explained by these three factors.
