[Partial response of liver metastasis from colon cancer following intermittent oral administration of TS-1 after intra-hepatic arterial single injection of CDDP, doxorubicin and 5-FU].

An intrahepatic arterial injection of CDDP, doxorubicin and 5-FU, followed by 17 courses of oral TS-1 administration (80 mg/day x 14 days, q=28 days), induced a partial response for 9 months after 18 months of stable disease in a 76-year-old male with asynchronous liver metastasis due to ascending colon cancer. TS-1 showed an excellent anticancer effect against colorectal metastatic liver cancers for a long time without loss of QOL or safety.
