[摘 要] 来曲唑是一种高效的非甾体芳香化酶抑制剂,通过抑制芳香化酶活性降低雌激素水平,在生育力保存领域,尤其是
恶性肿瘤患者中,具有重要的应用价值。对于雌激素敏感型恶性肿瘤如乳腺癌患者,来曲唑可在促排卵过程中降低体内雌激
素水平,从而减少传统促排卵过程中高雌激素对肿瘤的不利影响,同时有效促进卵泡发育。然而,来曲唑带来的体内低雌激素
水平环境可能导致卵子成熟度下降、胚胎质量下降及胚胎着床率降低。未来需进一步开展大规模临床研究,以明确来曲唑在
生育力保存中的长期安全性与疗效,为恶性肿瘤患者的生育力保存提供更加精准的治疗策略。

[Abstract] Letrozole is a highly effective non ⁃ steroidal aromatase inhibitor that reduces estrogen levels by inhibiting aromatase
activity. It has important application value in the field of fertility preservation,especially in patients with malignant tumors. For
patients with estrogen⁃sensitive malignant tumors such as breast cancer,letrozole can reduce the concentration of circulating estrogen
in the body during ovulation induction,thereby reducing the adverse effects of high estrogen on tumors during traditional ovulation
induction,and effectively promote follicular development. However,the low estrogen level environment in the body brought about by
letrozole may lead to decreased oocyte maturity or embryo quality and reduced embryo implantation rate. Further large⁃scale clinical
studies are needed in the future to clarify its long⁃term safety and efficacy in fertility preservation,and provide more precise treatment
strategies for fertility preservation in patients with malignant tumors.
