Abstract :

The aim of this study was to investigate the therapeutic efficacy of intra-arterially administrated 188 Re-human serum albumin microsphere ( 188 Re-HSAM) in the GP7TB hepatoma model. Male F344 rats were done with intrahepatic inoculation with GP7TB 1 mm 3 cubes. These studies were performed on rat at 26 d after tumor inoculation. The efficacy of 188 Re-HSAM was performed by a single-dose treatment in GP7TB hepatoma rat via intra-arterial route. Rats were checked for survival every day until death. The body weight was measured once a week. In efficacy study, the median survival time for the rat (n=3), which received normal saline was 80 d. The median survival times for the mice treated with 10 mCi (n=3), 4.8 mCi (n=3) and 2.9 mCi (n=3) of 188 Re-HSAM were 130 d (P=0.003), 90.25 d (P=0.035) and 83.5 d (P=0.617), respectively. The increase in life span of 10 mCi, 4.8 mCi and 2.9mCi of 188 Re-HSAM were 62.5%, 12.8% and 4.4% respectively. The therapeutic studies of 188 Re-HSAM demonstrated better survival time and therapeutic efficacy for rat with increased dose in the GP7TB hepatoma model. These results suggested that intra-arterial administration of 188 Re-HSAM could provide a benefit and promising strategy for delivery of radiotherapeutics in oncology applications.
