Coverage of the hospital-based cancer registries and the designated cancer care hospitals in Japan

Abstract

Background 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. Methods 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. Results 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. Conclusions 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.

Impact of the COVID-19 pandemic on the diagnosis of cancer in Japan: analysis of hospital-based cancer registries

“…We used the national HBCR data from 735 hospitals, including all cancer care hospitals designated by the Ministry of Health, Labour and Welfare in Japan and other participating hospitals, which provided all data for cancer cases during 2016–2020. The HBCR database covers \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}$\sim$\end{document} 72% of patients newly diagnosed with cancer in Japan ( 15 ). Trained cancer registrars in a hospital registered each cancer case in the HBCR based on standardized rules and criteria ( 16 ).…”

Clinicopathological features of adrenal malignancies: Analysis of hospital‐based cancer registry data in Japan

“…These data from the HBCR cover at least 70% of all cancers but this coverage may vary by cancer type or patient age. 11 Patient information for newly diagnosed cases are routinely collected by DCCHs and cancer registrars record the details of diagnosed cancer cases based on standardized criteria. We thus used HBCR data from Japan's DCCHs and other core cancer care hospitals to analyze clinicopathological features of adrenal malignancies that were diagnosed.…”

The epidemiology of rare types of hepatobiliary and pancreatic cancer from national cancer registry

“…Monitoring the actual condition of cancer treatment is essential in improving the quality of cancer care. In Japan, the data from hospital-based cancer registries (HBCRs) of cancer care hospitals designated by the national government (designated cancer care hospitals [DCCHs]) has been collected by the National Cancer Center to have a clinical picture of cancer practice and treatment since 2007 [ 2 , 3 ]. Epidemiological information, including the incidence and distribution of age, sex, and region were mainly estimated by HBCRs and organ-specific cancer registries, and comprehensive actual numbers were insufficient.…”
