The quality of the data recorded by the British Columbia Cancer Registry for 521 new cases of invasive cervical cancer was evaluated. The registry's pathological diagnosis in all new registrations of invasive cervical cancer diagnosed in British Columbia between 1977 and 1979 was compared with a best estimate of the true diagnosis, which was determined from the results of the provincial cervical cytology screening program and the clinical charts at the Cancer Control Agency of British Columbia. The registry's data overestimated the true incidence of invasive cervical cancer by approximately 55%, since 184 (35%) of the cases were incorrectly registered. Of the 184, 141 (77%) were cases of preinvasive cervical cancer, 26 (14%) did not meet the criteria for a true case (i.e., they were not newly diagnosed in British Columbia between 1977 and 1979) and 17 (9%) were cases of invasive cancer of another primary site. In addition, 28 cases of invasive cervical cancer diagnosed in the province during the study period had not been reported to the registry. Thus, both over-reporting and under-reporting occurred. There is a need for constant evaluation of registry data if cancer registries are to fulfil their potential contribution to cancer control programs and research.
对不列颠哥伦比亚癌症登记处记录的521例浸润性宫颈癌新病例的数据质量进行了评估。将该登记处在1977年至1979年期间诊断出的不列颠哥伦比亚省所有浸润性宫颈癌新登记病例中的病理诊断，与通过该省宫颈细胞学筛查项目结果及不列颠哥伦比亚癌症控制机构的临床图表确定的真实诊断的最佳估计值进行了比较。该登记处的数据将浸润性宫颈癌的真实发病率高估了约55%，因为有184例（35%）病例登记有误。在这184例中，141例（77%）为宫颈浸润前癌病例，26例（14%）不符合真实病例标准（即它们并非在1977年至1979年期间在不列颠哥伦比亚省新诊断出的病例），17例（9%）为其他原发部位的浸润性癌病例。此外，在研究期间该省诊断出的28例浸润性宫颈癌病例未报告给该登记处。因此，既有报告过多的情况，也有报告不足的情况。如果癌症登记处要充分发挥其对癌症控制项目和研究的潜在贡献，就需要不断评估登记处的数据。
