仅死亡证明（DCO）指数量化了死亡证明向登记处提供唯一通知的患者比例，是一种广泛使用的基于人群的癌症登记不完整性指标。本文提供了一个代数评估和DCO指数和癌症登记不完整性之间的关系的定量说明。结果表明，DCO指数和登记不完整性之间的关系是强烈依赖于病死率和未登记患者中癌症死亡的错误分类率。因此，DCO指数是一个很差的不完整性指标。类似的局限性也适用于DCN指数（死亡证明首次通知的病例比例），该指数已被提议作为衡量不完整性的替代指标。
The death certificate only (DCO) index, which quantifies the proportion of patients for whom the death certificate provides the only notification to the registry, is a widely used measure of incompleteness of population-based cancer registration. This paper provides an algebraic assessment and a quantitative illustration of the relationship between the DCO index and incompleteness of cancer registration. It is shown that the relationship between the DCO index and incompleteness of registration is strongly dependent on the case fatality rate and the misclassification rates of cancer deaths among unregistered patients. Therefore, the DCO index is a very poor indicator of incompleteness. Similar limitations apply to the DCN index (proportion of cases first notified by death certificate), which has been proposed as an alternative measure of incompleteness.
