Long survival in a case of unresectable hepatic metastasis from rectal carcinoma treated with second-look hepatectomy plus pharmacokinetic modulating chemotherapy (PMC)

A 67-year-old female with rectal cancer and multiple liver metastases underwent low anterior resection by total mesorectal excision (TME), cholecystectomy and hepatic arterial cannulation in June 1995. She was treated with hepatic arterial infusion chemotherapy (HAI) (5-FU 600 mg/m2/day x 2 days/w) and oral UFT (400 mg/body, 5 days/w) once a week for 6 months on an outpatient basis. As the metastatic foci of the liver significantly decreased (83.3%) and extrahepatic disease were not observed, partial resection of the liver (second-look hepatectomy) was performed in March 1996. She continued arterial infusion PMC and venous infusion PMC as an outpatient. During the follow-up period a lung metastasis appeared in November 1997. Her regimen was changed to modified PMC with MMC (mitomycin C) and CPT-11. She has been managed at our outpatient clinic while the lung metastasis remained but with no liver metastasis for 57 months after the first operation, until the present. Second-look hepatectomy and PMC with a two-way port system was a useful option for unresectable hepatic metastases from colorectal carcinoma.
