Incompleteness of ascertainment of new cases of any disease leads to underestimation of its incidence rate and may result in false assumptions about incidence trends if incompleteness varies over the course of time (Fraser et al., 1978). We report an attempt to assess the completeness of ascertainment in a cancer registry in the North-Western Region of England using a method based on independent comparison with accurate morbidity data. A total of 1955 verified cases of cancer from 5 independent sources covering 11 sites were used in the study. The corrected mean level of overall registration completeness was found to be 94% but this varied appreciably with site and source of data. Independent comparison is recommended as an effective method for estimating the completeness of cancer registration.
任何疾病新病例确诊的不完整性都会导致其发病率被低估,如果这种不完整性随时间变化,可能会导致对发病趋势的错误假设(弗雷泽等人,1978年)。我们报告了一项尝试,使用基于与准确发病数据进行独立比较的方法,评估英格兰西北地区一个癌症登记处确诊的完整性。该研究共使用了来自5个独立来源、涵盖11个部位的1955例经核实的癌症病例。发现总体登记完整性的校正平均水平为94%,但这因数据的部位和来源而有明显差异。建议将独立比较作为估计癌症登记完整性的有效方法。
