Table 6. Pathology findings.

	Pathology findings
Patient 1	Complete necrosis of two lesions (5.2 and 2.4 cm). Glass beads predominantly in areas of sclerosis both within and surrounding the lesions. Mild parenchymal hemorrhage in the immediate peritumoral liver. Hepatic parenchyma away from the lesions with mild steatosis.
Patient 2	Innumerable metastatic foci ranging from 0.4 to 4.5 cm. The largest lesion was completely necrotic with no viable tumor. Glass beads within the necrotic target lesion and throughout the liver including the portal vessels. Hepatic parenchyma away from the lesions without fibrosis.
Patient 3	Complete necrosis of two lesions. The portal vein showed luminal sclerosis with occasional glass beads without viable tumor. Rare glass beads in gallbladder wall with associated sclerosis and bile infarcts. Hepatic parenchyma away from the lesion without fibrosis.
Patient 4	Five viable lesions ranging in size from 0.5 cm to 2.3 cm with 20% tumor necrosis. Resin beads seen within gallbladder vessels and lymph node without associated tissue response. Beads also seen within viable tumor. Clustered beads in peritumoral vessels and vessels away from tumor.
