[Cancer board--new medical system in cancer clinic].

To proceed with more patient-oriented cancer medicine, the development of a new medical system is necessary in Japan. In Ariake Hospital of the Japanese Foundation for Cancer Research, a new medical system has been developed, which is composed of a common outpatient clinic and a conference system. The core conference system is called "Cancer Board". The practice of patient-oriented medicine in gastroenterological cancer has been introduced as a sample of the Cancer Board system in our hospital.
