[The future of chemotherapy at home--from outpatient chemotherapy to chemotherapy at home].

Chemotherapy for colorectal cancer has changed greatly. A continuous systemic chemotherapy like FOLFOX or FOLFIRI became a standard. It is necessary to get sufficient knowledge and technique of chemotherapy for an infusion port system and a portable pump system. The risk management aspect is very important. Both strict and steady drug mixing and an administration system are necessary. It is also important to make a 24-hour surveillance system for any unusual conditions. The hospital as a whole must come to grips with these problems. The chemotherapy at an outpatient clinic or home will become a standard in the near future because it preserves the patients' QOL.
