Chemoembolization and Radioembolization for Difficult Liver Tumors; Choice May Depend on Blood Flow

Two-thirds of primary liver cancer patients and 90 percent of secondary liver cancer patients have inoperable tumors that are unresponsive to systemic chemotherapy and may benefit from transarterial chemoembolization or radioembolization with yttrium-90 (Y-90), both minimally-invasive, palliative procedures. Although research shows transarterial chemoembolization and Y-90 are usually equivalent treatments for most intermediate-stage hepatocellular carcinomas (HCCs)1, Heart and Vascular Institute considers tumor blood supply when deciding which therapy would be most beneficial for a specific patient.

Image on the left: Pre-chemoembolization axial, contrast-enhanced CT scan at the level of the liver. White arrow shows a hypervascular lesion (33.8 mm x 31.6 mm) in segment 7 of the liver consistent with hepatocellular carcinoma.
Image on the right: Post-chemoembolization axial, contrast-enhanced CT scan at the same level as the previous image. White arrows show the treated lesion (22.4 mm x 24.0 mm) in segment 7. The lesion is no longer enhancing and has decreased in size.
