[Assessment of colorectal cancer patients exhibiting bilobular multiple hepatic metastases].
We assessed 23 patients who underwent surgical therapy of hepatectomy or microwave coagulation therapy (MCT) for bilobular multiple hepatic metastatic foci following curative resection of the primary lesion of colorectal cancer. Hepatectomy was the first surgical therapy for 10 patients, and 6 of them received combined intra-arterial chemotherapy. All 13 patients in the MCT group received intra-arterial chemotherapy, and 8 of them underwent combined hepatectomy. The two-year survival rate of the hepatectomy group, classified according to the first surgical therapy, was 40% against 52% in the MCT group. In comparison with the H2 (2-5 foci) patients in the hepatectomy group, there were 7 H2 patients in the MCT group, and the two-year survival rate of these 7 patients was 50%. No significant difference was observed between hepatectomy and the MCT as the first surgical therapy. The survival rates of the 5 patients who received treatment for recurrence after the first surgery and of the 18 patients without any recurrence treatment were 80% and 40%, respectively. No significant difference existed between the two groups, but a p value of 0.06 was noted. MCT was considered to be useful local therapy for cancer as the first therapy and as a therapy following recurrence.
