Clinical outcome of curative liver resections using a microwave tissue coagulator for primary hepatocellular carcinoma

Abstract

We report the clinical outcomes of 214 patients with HCC who underwent partial liver resections using MTC in accordance with the tumor sizes for patients with HCC.
Seventy-three percent of the patients suffered from type C hepatitis and 45% of the patients had pathologically proven liver cirrhosis. The overall patient survival rates were 95, 79, and 65 % at 1, 3 and 5 years, respectively. Disease-free survival rates were 81, 53, and 32% at 1, 3 and 5 years, respectively. Postoperative morbidity was 28% and hospital mortality was 2.4%. Complications in most patients were well controlled although intractable bile leakage was observed in three patients.
In conclusion, liver resections using MCT, in accordance with tumor sizes, can be achieved safely with acceptable results and without the need to use special techniques.
