Abstract

This study focused on the differences in the patterns of care for prostate cancer patients treated with radical external beam radiotherapy between Japan and the United States. Results from the 1999-2001 Japanese Patterns of Care Study (PCS) survey were compared with those of the 1999 PCS in the United States. In addition, the changing trends in the patterns of care between Japan and the United States were also analyzed. Patients in Japan were found to have more advanced primary disease than those in the United States, but the proportions of advanced disease have gradually decreased in Japan. The distributions of CT-based treatment planning, conformal therapy and higher doses were higher in the United States, and a drastic change in these parameters occurred in the United States, while only moderate changes occurred in Japan. These results indicate that patterns of care for prostate cancer in Japan are considerably different from those in the United States, and the changing trends in the patterns of care are also different between the two countries.
