Abstract

Unresectable primary and secondary liver malignancies present a major problem in the treatment of solid tumors. Transarterial radioembolization (TARE) is an increasingly used technique for treating various types of malignant liver tumors. This approach is appealing, as the mechanism of action is independent from other loco-regional treatments and potentially complementary to systemic therapies. There are two commercially available products in use for TARE: 90Y-resin and 90Y-glass microspheres. Currently available data indicates TARE so be safe and effective in hepatocellular carcinoma (HCC) and metastatic liver disease. In HCC the results compare well with chemoembolization, while the role of TARE in combination with kinase inhibitors has yet to be established. Current data on TARE in metastatic liver disease is promising, but there is a strong need for prospective randomized trials comparing TARE and modern chemotherapeutic regimen to support the growing role of TARE in metastatic liver disease.

Core tip: Transarterial radioembolization (TARE) with 90Y microspheres is a targeted therapy indicated for unresectable primary and secondary liver malignancies. Current data proves its safety and effectiveness, but its definitive role in the treatment of hepatocellular carcinoma and metastatic liver disease within interdisciplinary treatment algorithms is still to be established. There is a strong need for randomized controlled trials comparing TARE to transarterial chemoembolization in primary liver cancer and to modern chemotherapeutic regimen in metastatic liver disease.
