[Outcomes of patients undergoing microwave coagulation therapy for liver metastases from colorectal cancer].
To evaluate the efficacy of microwave coagulation therapy (MCT) for liver metastases from colorectal cancer, we analyzed the survival and the disease-free survival rate. From 1990 to 2001, 18 patients with liver metastases measuring < or = 3 cm in diameter and number of metastases < or = 3 were treated with MCT. The 3- and 5-year survival rates were 62% and 18%, respectively. These results are almost equal to those for liver resection. The disease-free survival rate was 86% and 52%, respectively. Local recurrence has not been observed, which puts the disease-free interval over 24 months. MCT can be considered an effective therapy for liver metastases from colorectal cancer.
