We analyzed the clinicopathological factors in two cases of local recurrence after a disease-free interval (DFI) of more than 12 months following microwave coagulation therapy (MCT) for liver metastases from colorectal cancer. Case 1: A local recurrence was diagnosed at 14 months after MCT for a liver metastasis of 20 mm in diameter from rectal cancer. Following liver resection, the patient remains alive without recurrence at 9 months. Case 2: A local recurrence was diagnosed at 19 months after MCT for a liver metastasis of 20 mm in diameter from rectal cancer. After MCT, the patient remains alive without recurrence at 36 months. We treated two patients with local recurrence who have more than 12 months' DFI after MCT for liver metastases from colorectal cancer. MCT or liver resection was performed as a curative therapy in these cases. Caution is recommended for local recurrence at more than 12 months after MCT for liver metastases from colorectal cancer.
