摘要
In May 2005, a 79-year-old woman was referred to our hospital with complaints of right lower quadrant mass and feces mixed with blood. After examination, she was diagnosed with ascending colon cancer and synchronous multiple liver metastases. Postoperative diagnosis after right hemicolectomy and D3 lymph node dissection was T2, N1, H2, P0, M0, and Stage IV. One month after the operation, we started a combination chemotherapy using 5-FU plus UFT as pharmacokinetic modulating chemotherapy with hepatic arterial infusion (HAI-PMC). But abdominal CT scan revealed the increase of multiple liver metastases, PD, after 4 courses of treatment. We then changed to modified HAI-PMC (additional CPT-11, once every four weeks), but had to cancel it due to her exhaustion and inappetence. Therefore, S-1 was started from October, 2005. Each course consisted of daily oral administration of 80 mg S-1 for 4 weeks and withdrawal for 2 weeks. After 4 courses, abdominal CT scan revealed a reduction in the number of multiple liver metastases, PR. PR has continued for a long term to date. As an adverse event, we had grade 3 neutropenia and grade 2 diarrhea in January 2009, and we changed the administration method (80 mg S-1 for 2 weeks and withdrawal for 1 week). She continues to undergo outpatient treatment with good QOL without a lesion for 4 years and 6 months. S-1 is expected to be an effective agent for the treatment of advanced colon cancer.
