[Indication for surgical and microwave coagulation therapy for multiple (> or = 5) bilobar liver metastases from colorectal cancer].
We analyzed methods and clinicopathological factors for multiple (> or = 5) bilobar liver metastases (H3) from colorectal cancer and evaluated the indication of surgical and microwave coagulation therapy (MCT) for them. Twenty-four patients with H3 underwent surgical therapy and were divided into two groups. Group a: 9 patients with a prognosis of more than 700 days. Group b: the remaining 15 patients. There was no significant difference in prognosis between those receiving MCT and resection + MCT as a surgical therapy. The number and maximum diameter of tumors tended to be smaller in Group a. The number of tumors was less than or equal to 9 and the maximum size of the tumors was 38 mm. Moreover, the tumor could be controlled by MCT alone if the tumor size was less than 30 mm. MCT is a useful therapy for these cases and the indication for surgical therapy may depend on the number and maximum size of tumors.
