Hormotherapy and chemotherapy are still the most important palliative therapeutic approaches for androgen-sensitive prostate cancer (PCa). Recently, the combination of hormotherapy and chemotherapy, namely, chemohormonal therapy has aroused considerable attention. Although synergistic chemohormonal therapy can improve PCa suppression efficacy and prolong the lives of patients, it also leads to severe adverse effects, that is, hormonal tolerance caused by hormotherapy, and leukemia or neutropenia caused by chemotherapy. Therefore, alleviating the adverse effects and improving anti-PCa efficacy are the focuses of the chemohormonal therapy for future researches. In this study, the commercial androgen-deprivation therapy (ADT), polyester microsphere Enantone (ENT), and polypeptide micelles loaded with a clinical antitumor agent mitoxantrone (MTO) are employed for micro/nanocarrier-assisted chemohormonal therapy. Encouragingly, the combined chemohormonal therapy significantly boosts antitumor efficacy and ameliorates side effects in preclinical assessments. With these benefits, the micro/nanocarrier-assisted chemohormonal therapy can be incorporated as an efficient clinical strategy for PCa patients.

聚合物微/纳米载体辅助的协同化学激素疗法治疗前列腺癌

对于雄激素敏感型前列腺癌(PCa),激素疗法和化学疗法仍然是最重要的姑息治疗方法。近来,激素疗法和化学疗法的组合,即化学激素疗法引起了相当大的关注。尽管协同化学激素疗法可以提高PCa抑制效果并延长患者的寿命,但也会导致严重的不良反应,即激素疗法引起的激素耐受性以及化学疗法引起的白血病或中性粒细胞减少。因此,减轻化学药品的不良反应和提高其抗PCa的功效是化学激素治疗的重点。在这项研究中,商业性雄激素剥夺疗法(ADT),聚酯微球庚烯酮(ENT),载有临床抗肿瘤药米托蒽醌(MTO)的多肽胶束用于微/纳米载体辅助化学激素治疗。令人鼓舞的是,在临床前评估中,化学激素联合治疗显着提高了抗肿瘤功效并改善了副作用。有了这些好处,微/纳米载体辅助的化学激素治疗可以作为PCa患者的有效临床策略。
