AIM:To assess the efficacy of combined transcatheter arterial chemoembolization(TACE)and percutaneous microwave coagulation therapy(PMCT)for small hepatocellular carcinoma(HCC). METHODS:Thirty-five patients with a total of 41 HCC nodules(≤3 cm in diameter)were treated with TACE followed by computed tomograghy(CT)-guided percutaneous microwave coagulation therapy(PMCT) within 1-3 wk. RESULTS:By biopsies and enhanced CT scans, complete necrosis of the tumor and 3-5 mm of the surrounding non-cancerous area were observed in 34 foci.In seven foci,incomplete necrosis of the surrounding parenchyma was observed.Serum alpha- fetoprotein(AFP)levels returned to normal 10 d after treatment in 25 patients who originally had high serum AFP levels.The follow-up period was 6-31 mo,and all patients remained alive.One patient had a recurrence in the subsegments of the liver,and another patient had a recurrence near the original lesion. CONCLUSION:Combined therapy with TACE and PMCT is a safe and effective treatment without severe complications for small HCC.

Serum alpha-fetoprotein (AFP) levels returned to normal 10 d after treatment in 25 patients who originally had high serum AFP levels. The follow- up period was 6-31 mo, and all of the patients were alive. One patient had a recurrence in the subsets of the liver, and another patient had a recurrence near the original lesion. CONCLUSION: Combined therapy with TACE and PMCT is a safe and effec tive treatment without severe complications for small HCC.
