Abstract
The Japanese Association for Therapeutic Radiation Oncology (JASTRO) has had a seminar for medical students since 1995. Some of participants become radiation oncologists, so the seminar is considered to be effective for increasing the number of radiation oncologists in Japan. To reveal the participants' knowledge, clinical experience and familiarity with radiation oncology, we performed a small examination and questionnaire survey. We found that the satisfaction with the lectures during the seminar depended on the students' previous experience and knowledge. The daily efforts of the teaching staff in medical schools seems to be necessary to motivate students in radiation oncology.
