[A five-year survived case of more than 5 cm colorectal liver metastases treated with intraoperative microwave coagulation therapy].
A 54-year-old man underwent Hartmann's operation for rectal cancer in October 2003. Diagnostic images showed a single liver tumor in segment 7 of the liver in March 2004. He had a non-B, non-C cirrhosis. Liver damage was defined as B and ICG retention rate after 15 minutes was 54%. Platelet count was 7x10(4)-11x10(4)/mm3 and PT activity was 59%. The S7 tumor size was 6.5 cm in diameter, and we planned a partial resection of the liver. Intraoperative histological diagnosis of needle biopsy showed a metastatic adenocarcinoma from rectal cancer. Because of tuberculous peritonitis, it was difficult to control oozing from dissected plane. Therefore, we changed the method of operation from a partial resection to microwave coagulation therapy (MCT). To avoid a deteriorating liver function, we did not perform any adjuvant chemotherapy. He is alive without recurrence for five years after surgery. Nevertheless metastatic liver tumor is more than 5 cm and in cirrhotic liver, if the tumor located superficial parenchyma, MCT may have a possibility to be a curative treatment.
