Abstract
To increase the number of radiation oncologists, the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) has provided a radiation oncology seminar for medical students and interns during the summer vacation since 1995. We examined the specialty of the 234 participants to reveal that seminar contributed to an increase of the number of radiation oncologists. Eighty five (36.3%) became radiologists and 41 (17.5%) chose radiation oncology as their specialty. The number of students who became radiation oncologists is significantly different in each of the seminars. There is the possibility that these seminar encourage students to choose radiation oncology as their specialty.
