RESUMO
Objective:To investigate the efficacy of stereotactic body radiation therapy with gamma-knife (γ-SBRT) combined with targeted drug sorafenib and hyperthermia for the treatment of recurrent and metastatic hepatocellular carcinoma. Methods:A total of 71 patients with recurrent and metastatic hepatocellular carcinoma were admitted from August 2007 to December 2009. Among these patients, 39 were treated with γ-SBRT and hyperthermia (group 1); 19 were treated with γ-SBRT combined with sorafenib and hyperthermia (group 2). Results: The total efficacy rate after a three-month treatment was 83.1% (59/71). In group 1, the following results were obtained:one-and three-year local control rates of 41.0%(16/39) and 18%(7/39), respectively;one-and three-year overall survival (OS) rates of 41.2% and 17.9%, respectively; and one- and three-year progression-free survival (PFS) rates of 38.4% and 15.4%, respectively. In group 2, the following results were obtained:one-and three-year local rates of 56.3%(18/32) and 28.1%(9/32), respectively;one-and three-year OS rates of 62.5%and 28.1%, respectively;and one-and three-year PFS rates of 59.4%and 25.0%, respectively. Significant differences in OS and PFS were observed between the two groups. Conclusion:The combination ofγ-SBRT with targeted drug sorafenib and hyperthermia can be used effectively to treat recurrent and metastatic hepatocellular carcinoma. Adverse reactions are mild, and patients can tolerate this treatment.
