Surgical treatment with microwave coagulo-necrotic therapy (MCN) and/or hepatic resection for small hepatocellular carcinoma

Abstract

In our institute, hepatic resection and/or MCN have been used for HCC. This study assesses the efficacy of these treatments, especially for small HCC measuring 2 cm or less in greatest diameter.
From July 1994 to March 2004, 60 patients with small HCC underwent hepatic resection (Hr) and/or MCN (Hr, 3; MCN, 55; Hr + MCN, 2).
The cumulative 1-, 3-, and 5-year survival rates in MCN group were 100, 97.0, 91.6%, in Hr group were 100, 100, 100%, and in Hr + MCN group were 100, 100, - %. The cumulative 1-, 3-, and 5-year survival rates of Liver damage (LD)-A group were 100, 100, 100%, of LD-B group were 100, 100, 92.3%, and of LD-C group were 100, 0% (p < 0.0001).
In conclusion, both Hr and MCN, especially MCN are the effective local treatment for small HCC with LD A or B.
