Outline of Final Research Achievements

With the development of medical technology, the results of treatment with anti-cancer drugs have improved, but countermeasures against late complications due to anti-cancer drugs remain a challenge. Our previous research has revealed that anti-cancer drugs that cause erectile dysfunction (ED) can be derived and that it persists even after drug withdrawal. Therefore, the purpose of this research was to clarify a novel therapeutic target for refractory ED caused by anti-cancer drugs.
For ED caused by the anti-cancer drug vincristine, we have found that two substances X and Y were observed to improve erectile function through improvement of vascular function. On the other hand, we also have found that two substances Z and T significantly improved erectile function in ED caused by the anticancer drug doxorubicin.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、抗がん剤治療後の勃起障害(ED)に対する新規治療ターゲットを導出することができ、治療のシーズを発見することができた。引き続き、詳細なメカニズムの解明が必要であるが、将来の治療への応用が期待される。
現在、がん治療成績が向上しており、抗がん剤治療後も生存し続けるがんサバイバーが増加しているが、晩期合併症の対策は遅れているとされている。本研究成果により、抗がん剤治療後のEDを含めた性機能障害の改善効果が得られれば、がんサバイバーの生命の質(QOL)の向上が期待される。
