Abstract:
Objective To compare the efficacy of open microwave ablation and repeat hepatectomy for recurrent small hepatocellular carcinoma.Methods The clinical data of 75 patients with recurrent small HCC who were admitted to our hospital from January 2007 to December 2010 were retrospectively analyzed.34 received microwave ablation (MWA group) and 41 received repeat hepatectomy (hepatectomy group).The perioperative condition,liver function recovery,the variation of AFP level,mobidities,hospitalization time and overall survival rate and disease-free survival rate were compared.Results The rate of complete elimination to tumor tissue was 100％ and the AFP levels returned to normal within 3 months in both groups.The mean average operation time in MWA group was shorter than that in hepatectomy group [(91 ±33) min vs (156 ±51) min,t =-6.399 5,P =0.000].The blood loss in MWA group was smaller than that in hepatectomy group [(87 ±62) ml vs (254 ± 134) ml,t =-6.691 5,P =0.000].Patients in PFRA group had a shorter hospital stay [(7.5 ± 2.2) d vs (11.3 ± 2.7) d,t =-6.588 8,P =0.000].The mobidities of the MWA group and hepateetomy group were 2.9％ (1/34) and 22.0％ (9/41),respectively (x2 =5.812 7,P =0.016).The overall survive rate of 1,3 and 5-year were 88.1％,68.8％ and 46.1％ in the MWA group,and 86.1％,71.5％ and 50.2％ in the hepatectomy group (x2 =0.16,P =0.692).The disease free survival rate of 1,3 and 5-year were 67.1％,38.2％ and 16.1％ in the MWA group,and 64.4％,45.5％ and 23.6％ in the hepatectomy group (x2 =0.03,P =0.870).Conclusions MWA can achieve survival benefits equivalent to hepatectomy for recurrent small HCC,and it is less traumatic.
