Hospital-based cancer registries were developed to describe and improve clinical care for cancer patients. We described the hospital-based cancer registry coverage as a reference for the users, including researchers, policymakers and clinicians.
The hospital-based cancer registry coverage was defined as the proportion of new cases registered in the hospital-based cancer registry to the National Cancer Registry as the denominator. To examine the coverage of respective cancer types, age groups and prefecture in the hospital-based cancer registry, cases were grouped based on the 10th International Statistical Classification of Diseases and Related Health Problems and were compared with the published report of the National Cancer Registry in 2017.
The overall hospital-based cancer registries coverage was 71.7%, and 52.5% of patients were treated at designated cancer care hospitals. The hospital-based cancer registries coverage and treatment rates at designated cancer care hospitals varied per cancer type, age group, and prefecture. The hospital-based cancer registries covered over 80% of the patients with cancers of the larynx, uterus, oesophagus, lip, oral cavity, pharynx and skin, whereas patients' coverage with thyroid cancer was relatively low. The hospital-based cancer registry coverage of young patients (<15 years) was >80%, whereas that for elderly patients (≥85 years) was <55%. The range of coverage in each prefecture was from 43.0 to 89.7%. Over 70% of the patients with cancers of the larynx, lip, oral cavity and pharynx were treated at designated cancer care hospitals.
The hospital-based cancer registry coverage is ~70% of all cancers. Because the coverage differed across cancers and age groups, the respective target groups' analysis should consider this factor.
医院癌症登记处的建立旨在描述和改善癌症患者的临床护理。我们描述了医院癌症登记处的覆盖范围，以供用户参考，包括研究人员、政策制定者和临床医生。
医院癌症登记处的覆盖范围定义为医院癌症登记处登记的新病例数占国家癌症登记处的比例。为了检查医院癌症登记处中各癌症类型、年龄组和地区的覆盖范围，根据第十次国际疾病和相关健康问题统计分类对病例进行分组，并与 2017 年国家癌症登记处公布的报告进行比较。
医院癌症登记处的总体覆盖范围为 71.7%，52.5%的患者在指定癌症治疗医院接受治疗。医院癌症登记处的覆盖范围和指定癌症治疗医院的治疗率因癌症类型、年龄组和地区而异。医院癌症登记处覆盖了超过 80%的喉癌、子宫癌、食管癌、唇癌、口腔癌、咽癌和皮肤癌患者，而甲状腺癌患者的覆盖范围相对较低。<15 岁的年轻患者的医院癌症登记处覆盖范围>80%，而≥85 岁的老年患者的覆盖范围<55%。每个地区的覆盖范围从 43.0%到 89.7%不等。超过 70%的喉癌、唇癌、口腔癌和咽癌患者在指定癌症治疗医院接受治疗。
医院癌症登记处的覆盖范围约为所有癌症的 70%。由于癌症和年龄组之间的覆盖范围存在差异，因此各自的目标群体分析应考虑这一因素。
