Population-based cancer registries represent a potentially valuable tool to evaluate treatment; however, information on the completeness of registry treatment data is sparse.
To evaluate the completeness of registry treatment data for patients with colorectal cancer and to identify predictors of complete reporting.
We surveyed physicians or reviewed office records of 1956 northern California patients diagnosed with colorectal cancer during 1996 to 1997 to assess the completeness of registry data regarding use of adjuvant chemotherapy and radiation therapy.
For patients with a record of receipt of chemotherapy in either the registry or physician survey, information was in the original registry records for 82.0%. In the multivariate analysis, completeness of chemotherapy reporting was lower for patients aged 65 to 74, those with colon cancer, [corrected] and higher for patients treated in hospitals that are part of a large health maintenance organization (HMO). For patients with a record of receipt of radiation therapy, information was in the original registry records for 90.2%. In the multivariate analysis, completeness of radiation therapy reporting was higher for patients aged 18 to 54 and those treated in HMO hospitals.
Because the completeness of the registry treatment data varied by patient and hospital characteristics, use of registry data without supplementation could bias estimates of the proportion of patients treated, and of the patient and provider characteristics associated with treatment. Enhanced cancer registry data could be a valuable component of population-based cancer data systems for assessing quality of cancer care.
基于人群的癌症登记系统是评估治疗效果的一个潜在有价值的工具；然而，关于登记系统治疗数据完整性的信息却很稀少。
评估结直肠癌患者登记系统治疗数据的完整性，并确定完整报告的预测因素。
我们调查了医生或查阅了1956名1996年至1997年期间在北加利福尼亚被诊断为结直肠癌患者的办公室记录，以评估登记系统中关于辅助化疗和放疗使用数据的完整性。
对于在登记系统或医生调查中有化疗记录的患者，82.0%的信息存在于原始登记记录中。在多变量分析中，65至74岁的患者、患有结肠癌的患者化疗报告的完整性较低，而在大型健康维护组织（HMO）所属医院接受治疗的患者化疗报告的完整性较高。对于有放疗记录的患者，90.2%的信息存在于原始登记记录中。在多变量分析中，18至54岁的患者以及在HMO医院接受治疗的患者放疗报告的完整性较高。
由于登记系统治疗数据的完整性因患者和医院特征而异，在没有补充的情况下使用登记系统数据可能会使对接受治疗患者比例以及与治疗相关的患者和医疗服务提供者特征的估计产生偏差。强化的癌症登记数据可能是基于人群的癌症数据系统中评估癌症护理质量的一个有价值的组成部分。
