The aim of this nationwide survey was to investigate the use of Kampo medicine by Japanese physicians who worked in the core cancer treatment hospitals which were designated by Ministry of Health, Labour and Welfare. Among the 900 physicians surveyed, 92.4% reported having prescribed Kampo medications, of whom 73.5% reported having prescribed them for cancer patients. Despite this high percentage and the finding that only 9.7% of the physicians reported that they considered Kampo medications to be harmful, only 23.1% of the physicians expressed high expectations of the efficacy of Kampo medicine in tumor suppression and the exertion of immunostimulatory action. In contrast, many cancer patients have expressed the belief that Kampo medications can suppress tumor growth, and several studies have reported that they exert immunostimulatory action. To resolve this discrepancy in patient and physician expectations and to clarify the research findings, further research into the effectiveness and harmfulness of Kampo medicine in cancer treatment is warranted.
