[Present status and issues regarding X-ray medical checkup vehicles in preventive medicine: usefulness of mass screening for lung cancer by an X-ray medical checkup vehicle].
Although the prevention of habituation-related diseases has become an important topic in Japan, the early detection of cancers such as lung, gastric, and breast cancers is an important issue for X-ray-related imaging modalities. High cost-benefit and cost-effectiveness are necessary to perform mass screenings such as those for lung cancer. In order to assess cost-benefit and cost-effectiveness, a total of 100 institutions nationwide were investigated, with a 41% of recovery rate. There were at least one or two institutions in each prefecture. Cost-benefit analysis was based on factors including the price of the medical check-up vehicle, its service life, and income from the examinations. The mean price of medical check-up vehicles used for chest X-ray examinations was 4,445,000 yen. Cost-effectiveness analysis was based on the expense incurred to discover one lung cancer. According to our research, the cost-effectiveness involved in detecting one lung cancer by conventional chest X-ray examination was about 2,270,167 yen/person. Since this amount seems unduly high, it is necessary to improve cost-effectiveness.
