Outline of Final Research Achievements

A prospective multi-center clinical trial was performed to evaluate the clinical utility of hepatic arterial embolization using microsphere in patients with treatment refractory liver metastases. The primary endpoint was response rate at 1 month after embolization, and secondary ones were over all and progression-free survival, and safety. Microsphere was injected slowly from the hepatic artery until hepatic arterial blood flow stagnated. The response rate was as high as 50% at 1 month after embolization with a median survival of 9 months and progression survival of 4 months. There was no severe (G3 or 4) adverse events but increase in liver enzyme. Embolization using microsphere is a safe and useful treatment for patients with treatment refractory liver metastases.

Academic Significance and Societal Importance of the Research Achievements

本邦では死亡原因の第一位が癌である。癌患者の増加とともに肝転移患者の数も増加している。肝転移の治療は主に切除や薬物療法であるが、これら治療が対象外となると、治療法がなく、患者さんの予後は悲惨である。このような患者さんを対象に新たな治療法を模索して行ったのがこの前向き臨床試験である。結果は良好なもので、今後、多くの患者さんの福音になっていく可能性が示された。
