A novel extracorporeal blood circulating PDT system for treating hematopoietic malignancies. (a,b) 5-ALA was administered orally, and the blood was then circulated extracorporeally through medical tubes with a blood pump. Circulating blood is irradiated with light at 630 nm, and the treated blood is returned to the body. (c) Cross-sectional shape of the blood circuit tube.
