Comparison of survival rates for patients with hepatocellular carcinoma among laparoscopic microwave coagulation, percutaneous microwave coagulation and percutaneous ethanol injection

Abstract

25 patients with solitary HCC were firstly treated by laparoscopic microwave coagulation (LMC), 14 were firstly treated by percutaneous microwave coagulation (PMC), and 39 were initially treated by percutaneous ethanol injection (PEI). For these 78 cases, we analyzed the survival rates and compared the rates among LMC, PMC, and PEI group. 5-year survival rates were 52% in LMC group, 46% in PMC group, and 58% in PEI group. The differences of survival rates were not statistically significant among LMC, PMC, and PEI group. Next, we analyzed survival rates between microwave coagulation (MC) and PEI. When HCC were 20mm or less, 5-year survival rates (45%) in MC group were almost the same percentage as in those (65%) of PEI group (p=0.48). However, when HCC were larger than 20mm, 5-year survival rates (80%) of MC group were significantly higher than those (40%) of PEI group (p=0.011).
