ABSTRACT
Although surgery remains as a gold standard line for management of hepatocellular carcinoma [HCC], many cases are not candidates for surgery due to underlying chronic liver disease and limited functional reserve even with recent advances in the field of surgery. At the same time several local ablative techniques have emerged and proved to be minimally invasive and effective measures for in situ control of HCC, of these techniques, radiofrequency ablation [RFA], and percutaneous ethanol injection [PEI]. The aim of the current study was to evaluate the safety and efficacy of RFA and ethanol injection for the treatment of HCC, to reach a protocol for proper management of unresectable HCC and, also to assess the quality of life before and after each technique. In the current study we had two groups of patients with HCC on top of cirrhosis due to hepatitis C virus [HCV] infection, one of them was subjected to RFA [G 1] and the other [G2] was subjected to PEI as therapeutic modalities for their HCC. As regards GI, it included 30 patients with 36 HCC lesions with a mean size of 3.02 cm which were treated by percutaneous US guided RFA using cooled-tip electrodes with a mean of 1-2 sessions of RFA. Studied patients were followed over variable periods that ranged between 6-18 months with a mean of 11.6 months. The responses to therapy were as follows: Complete ablation in 32 out of 36 lesions [88.8%], partial response in 3 out of 36 lesions [8.3%], recurrence in 3 [8.3%] lesions, and newly developed lesions in 7 cases. G2 included 20 patients with 26 HCC lesions with a mean size of 3cm for which we used PEI modality, we found that 21 out of 26 lesions [80.7%] had complete response, 4 out of 26[15.3%] had partial response and one [3.8%] showed local recurrence, and newly developed lesions were seen in 5 cases. The period of follow up ranged from 4-12 months with a mean of 10 months. As regards survival, one year survival rate was 75% in GI and 80% in G2. We concluded that, both RFA and PEI are safe and effective procedures and result in significant improvement in quality of life in patients with unresectable HCC. RFA showed higher rate of complete necrosis and requires fewer sessions than PET in the management of HCC
