Outline of Final Research Achievements

In order to obtain pancreatic cancer tissue-directed anticancer agents, liposome-conjugated FDG for use in FDG-PET testing was prepared. We studied the therapeutic strategy of the combination of gemcitabine and nab-paclitaxel, which is used as standard therapy for pancreatic cancer in clinical practice, by replicating the combination therapy with FDG-conjugated liposome-encapsulated anticancer agents. The in vivo accumulation and therapeutic effects of FDG-conjugated liposome-incorporated fluorescent reagents and anticancer agents suggested that the therapeutic strategy using FDG-conjugated liposome-incorporated anticancer agents may be effective for pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements

FDG結合リポソーム内包抗がん剤による治療戦略が膵癌に対しても有効である可能性が示唆され、特に、既報よりも40倍少ない用量での投与でも治療効果が得られたことから、FDG結合リポソーム内包ゲムシタビンの治療効果は良好であり、FDG未結合のリポソーム内包ゲムシタビンよりも治療効果は良好な傾向があったことからFDGを結合させることの上乗せ効果が示唆された。予後の極めて悪い膵癌に対する有効な治療戦略である可能性が示され、実用化が可能であれば今後膵癌の治療成績が向上が期待され大きな社会的意義が得られる可能性がある。
