ABSTRACT
PURPOSE:
Lipiodol is used for targeting liver cancers by administrating through the hepatic artery. In the present study, feasibility of Re-188-sulfur colloid suspension in lipiodol as a liver cancer targeting agent was investigated. MATERIALS ANDMETHODS:
Re-188-sulfur colloid was prepared, harvested by centrifugation, washed with organic solvent and then suspended into lipiodol. Biodistribution of Re-188-sulfur colloid in normal saline and its suspension in lipiodol in mice after 1 hr of injection through the tail vein were investigated. Biodistribution and autoradiography of tumor-bearing liver was acquired after 5 min post-injection into left ventricle of the tumor-inoculated rats.RESULTS:
After 1 hr of injection with Re-188-sulfur colloid suspensiob in lipiodol through the tail vein in normal mice (n=3), the uptakes in the liver and lung were 5.2+/-0.7 and 91.0+/-1.7% ID/organ, respectively. After 5 min of injection with Re-188-sulfur colloid suspention in lipiodol through the left ventricle in the tumor-inoculated rats (n=4), uptakes in the normal liver, hepatoma, and lung were 0.41+/-0.28, 1.88+/-1.57, and 1.65+/-1.54% ID/organ, respectively. And autoradiography of hepatoma showed increased uptake than normal liver tissues.CONCLUSION:
Re-188-sulfur colloid suspension in lipiodol injected through the artery shows higher uptake in the hepatoma than normal liver tissue that indicates the feasibility as a new radiopharmaceutical for therapy of hepatoma.
