[Microwave coagulo-necrotic therapy for hepatocellular carcinoma]

We performed microwave coagulo-necrotic therapy (MCN), a new surgical treatment for hepatocellular carcinoma (HCC) under laparotomy on 41 cases and under laparoscopy on 5 cases for a total of 46 cases (70 cancer nodules). The indications for MCN include: 1) cases in which an early recurrence is judged as likely to occur. For example, multinodular cases, or intrahepatic metastasis (im1-3) 25 cases (54.3%), 9 cases (19.6%) in which multiple adenomatous hyperplasia was detected, VP2 1 case (2.2%). 2) 7 cases (15.2%) in which if hepatectomy is conducted, there is a high risk of postoperative liver failure, or cases in which it is judged postoperative management will be very difficult. In only 4 cases was it because the patients requested laparoscopic MCN (lapa. MCN). Also, the tumor size was less than 15 mm in 4 cases, 16 to 20 mm in 6 cases, 21-30 mm in 21 cases, 31-50 mm in 6 cases, and larger than 51 mm in 9 cases (maximum 90 x 65 mm). Only 1 case who died on the 17th postoperative day due to sudden ventricular arrhythmia, and 3 cases who died cancer death at 1 year 6 months, 2 year 2 months, and 4 years 1 months after the operation for a total of 4 cases, so that 42 patients have survived 4 years and 3 months as of this writing. Thus MCN was in no way inferior to hepatectomy.
