A 75-year-old man with a history of sigmoid colon resection for Stage I cancer in 2001 visited in 2006 with severe perianal pain. Radiologic findings showed a solitary sacral tumor and aspiration biopsy cytology pathologically revealed the sigmoid colon cancer metastasis. Systemic chemotherapy and local irradiation showed no response. Transcatheter arterial injection chemotherapy (TAIC) of the tumor-feeding artery was performed 13 times. There were no obviously clinical change of tumor size and decrasing the tumor markers, and he died of multiple lung metastasis for 6 years 8 months after operation. The combination treatment of surgery, systemic chemotherapy and TAIC was needed to bone metastasis of the colon cancer. This rare case is reported and discussed.
