Abstract
A treatment method and a treatment system capable of effectively irradiating an antibody-photosensitive substance bound to a tumor cell with a near-infrared ray. The treatment method includes: intravenously administering the antibody-photosensitive substance; inserting a guide wire and a catheter into a main artery of an organ having the tumor cell; removing the guide wire; inserting an optical fiber into the catheter and advancing the optical fiber to a target position while checking a position of the optical fiber with an orientation marker disposed on the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane with the near-infrared ray from the optical fiber while reducing an influence of blood in the artery on the near-infrared ray after 12 hours to 36 hours from intravenous administration.
