The accuracy of patient-reported clinical information, including cancer stage, is not well understood. This study aims to evaluate the agreement between patient-reported survey data and clinical information recorded in hospital-based cancer registries (HBCR).
A total of 730 patients from 166 hospitals in Japan were randomly selected and informed that their survey responses would be validated against HBCR data. Demographic details, including age, sex, cancer stage, and cancer site, were recorded and compared with clinical data from the HBCR. Agreement rates between patients' self-reported demographic and clinical data and the corresponding HBCR records were analyzed. Logistic regression analysis was conducted to identify factors associated with accurate reporting of cancer stage information.
Agreement rates for age, sex, and cancer site were 99.4%, 99.8%, and over 90% across all cancer sites, respectively. The agreement rate for cancer stage reporting was 49.9%. Patients with stage IV cancer had the highest agreement rate at 68.4%. Patients under 75 years of age and those with specific cancer types demonstrated higher odds of reporting data consistent with HBCR records.
For cancer stage data, relying on more credible sources, such as cancer registries, is recommended over patient-reported information to ensure accuracy.
患者报告的临床信息（包括癌症分期）的准确性尚未得到充分了解。本研究旨在评估患者报告的调查数据与医院癌症登记处（HBCR）记录的临床信息之间的一致性。
从日本166家医院中随机选取730名患者，并告知他们的调查回复将与HBCR数据进行验证。记录包括年龄、性别、癌症分期和癌症部位在内的人口统计学细节，并与HBCR的临床数据进行比较。分析患者自我报告的人口统计学和临床数据与相应HBCR记录之间的一致率。进行逻辑回归分析以确定与准确报告癌症分期信息相关的因素。
所有癌症部位的年龄、性别和癌症部位的一致率分别为99.4%、99.8%和90%以上。癌症分期报告的一致率为49.9%。IV期癌症患者的一致率最高，为68.4%。75岁以下的患者和患有特定癌症类型的患者报告与HBCR记录一致数据的几率更高。
对于癌症分期数据，为确保准确性，建议依靠更可靠的来源，如癌症登记处，而不是患者报告的信息。
