Abstract
Background: The combination of systemic antiangiogenic therapy and transarterial chemoembolization (TACE) for the treatment of unresectable hepatocellular carcinoma (HCC) is the subject of several ongoing clinical trials. We present a series of patients treated with sorafenib and TACE at our institution, highlighting the technical challenges of combining these two modalities of treatment.
Methods: We retrospectively identified patients with HCC treated with TACE and sorafenib at our institution.
Conclusions: Our observations suggest that the biologically preferable strategy of continuous antiangiogenic therapy should be weighed against the possibility of suboptimal TACE due to poor visualization of lesions on angiography and safety.
Results: Five patients were treated with the combination of TACE and sorafenib given off-protocol based on preliminary reports in the literature. The first four patients started sorafenib 7 days prior to TACE resulting in intratumoral vascular pruning and poor visualization of lesions on angiography. This was managed by either superselective angiography or lobar TACE. The fifth patient stopped sorafenib 7 days prior to TACE with full visualization of multiple hypervascular lesions on angiography prior to embolization.
