[Successful resection of multiple liver metastases from rectal cancer following initial treatment using hepatic arterial infusion chemotherapy and radiotherapy].

A 69-year-old-man was referred to our hospital because of rectal cancer with multiple liver metastases. He was initially treated by hepatic arterial chemotherapy using an infusion reservoir (HACR) and radiotherapy for the rectal cancer. An abdomino-perineal resection and extended left lobectomy of the liver were performed and resulted in a reduction in size of the liver tumor. He was diagnosed as having a recurrent liver metastasis (S7) at 3 months after the operation, and was retreated by HACR in the outpatient clinic. A partial hepatectomy was reperformed at 6 months after the operation. Adjuvant hepatic arterial infusion chemotherapy (HAIC) was performed on an outpatient basis and the patient is doing well without recurrence or relapse. Preoperative arterial chemotherapy for metastatic liver tumor may be of some benefit for certain patients with far advanced colorectal carcinoma.
