Abstract/OtherAbstract:
AIM: To compare the pharmacokinetics of RF ablation with chemolipiodolization using cisplatin (CDDP) powder and miriplatin (MPT) in a porcine liver.
METHODS: Twelve pigs were divided equally into four groups. After each CDDP powder-lipiodol suspension (n=6;: groups A and B) or MPT-lipiodol suspension (n=6;:groups C and D) was injected into the lateral left artery, one RF ablation was performed at the lateral left lobe of each pig. Six pigs (groups A and C) were sacrificed on the same day as treatment, whereas the other pigs (groups B and D) were sacrificed 7 days after the treatment. The platinum concentrations in venous blood were assayed at 15, 60, and 120 min, and 7 days after treatment. The platinum concentrations in the ablated area and the surrounding liver were also examined.
RESULTS: Plasma platinum concentrations of the CDDP group peaked at 15 min, and then gradually diminished over time (μg units), while plasma platinum levels in the MPT group gradually increased over time (ng units). Liver tissue platinum concentrations of the CDDP group were significantly lower in non-ablative areas than in ablated areas at days 0 and 7, while liver concentrations of the MPT group were significantly higher in non-ablative areas than in ablated areas at day 7.
CONCLUSION: MPT may be a suitable chemotherapeutic agent to stagnate platinum in the surrounding liver.
