A case report of intra-hepatic arterial infusion of mitomycin C with degradable starch microspheres for liver metastases of sigmoid colon carcinoma

摘要

A 46-year-old man underwent polypectomy of sigmoid colon in January 1996. The adenocarcinoma invaded the submucosal layer, and sigmoidectomy and D2 lymph node dissection were performed one month later. Follow-up CT revealed liver metastases, and partial hepatectomy was performed in January 1998. Afterward, weekly high dose intra-hepatic arterial chemotherapy (5-FU: 1,000 mg/body) was performed 41 times, but CT revealed multiple liver metastases in October 1998. Therefore, intra-hepatic arterial infusion of mitomycin C (MMC) with degradable starch microspheres (DSM) was given in November 1998. As follow-up CT revealed that the liver metastases were growing, partial hepatectomy was performed again in March 1999. No carcinoma was seen in the resected liver. After the second hepatectomy, intra-hepatic arterial infusion of MMC with DSM was performed five times. No evidence of recurrence has been seen. Intra-hepatic arterial infusion of MMC with DSM is recommended for liver metastases of colorectal cancer asa second line treatment.
