Multiple liver metastases due to sigmoid colon cancer successfully treated by degradable starch microspheres (DSM)-TAE, radiofrequency ablation therapy, and Uzel/UFT

A69-year-old man was diagnosed with sigmoid colon cancer and underwent resection of the sigmoid colon. He was later diagnosed with multiple liver metastases 11 months after resection of the sigmoid colon cancer. He was treated by intraarterial chemoembolization using degradable starch microspheres (DSM) and radiofrequency ablation therapy. As a systemic therapy, combined oral administration of tegafur/uracil (UFT) and Leucovorin(Uzel) was started (UFT 450 mg/day, Leucovorin 75 mg/day, 4 weeks of therapy followed by a 1-week treatment break). Two months after 4 courses, the liver metastases had markedly diminished and CEA was within the normal range. The metastases had almost disappeared and tumor markers decreased to within normal limits. This treatment was very safe and effective. Such a strategic multidisciplinary treatment can lead to a better prognosis for colorectal cancer with liver metastases.
