Background:
At time of diagnosis 80% of the patients with hepatocellular carcinoma (HCC) could not be treated with surgical treatments, so that transarterial chemoembolization (TACE) was used as an neoadjuvant or palliative treatment modality.
Material And Methods:
60 patients were treated with 217 TACE courses, in the mean 3.6 TACE treatments per patient with an 4 week interval. TACE was performed with a dispersion of lipiodol, mitomycin C and spherex. 11 patients (18.3%) were treated in a neoadjuvant protocol with successful ablation. Lipiodol retention and size of the tumors were evaluated by CT and MRI.
Results:
60 patients were successful treated with TACE. After treatment a primary high lipiodol retention was displayed and in 68 (63.3%) patients a reduction of the tumor size and in 11 (20%) patients a reduction of tumor growth rate was noted. The 1 year survival rate was 59%. After response to TACE and reducing the tumor size 11 patients could be treated with MR-guided LITT 4 to 6 weeks post embolization.
Conclusion:
Chemoembolization is a minimal invasive and outpatient treatment protocol for HCC. TACE might be indicated as a palliative treatment to control the diseased liver. If repeated TACE alters the size and structure of primary unresectable HCC TACE expands the indication for MR-guided LITT.
