摘要
In medical care systems for cancer, it is important to consider the issues of standardization and centralization. In this study, we employed the Nagasaki Cancer Registry, which has a high registry rate, to investigate standardization and centralization for five major cancers, in addition to childhood malignancies (which are often rare types). Subjects were patients diagnosed with cancer and registered in the Nagasaki Cancer Registry between 1985 and 2004. For standardization, we calculated a Preference Index and five-year survival rate, and for centralization we investigated Pareto curves and Gini coefficients as well as the annual average number of cases per hospital. Results suggested that patients migrate to medical service areas different from where they reside in order to receive treatment at facilities thought to have a better record of treatment. In addition, while the number of patients and treatment facilities for childhood cancer was decreasing due to a decline in the number of children, the centralized tendency differed for the 12 diagnoses assessed. By conducting analyses based on population-based cancer registries using the evaluation methods employed in this study, it should be possible to investigate patients' migrant patterns, as well as to develop systems for providing medical care in secondary medical service areas.
