Oocyte and ovarian tissue harvesting and implantation may one day restore fertility in adolescent cancer survivors. Discussion ensues regarding ways to respect patients and address ethical issues in future clinical trials.
To offer a normative analysis of ethical issues in oocyte and ovarian tissue cryopreservation and implantation for adolescent cancer survivors.
Normative ethical analysis.
Oocyte and ovarian tissue harvesting and implantation hold promise in restoring fertility in adolescent cancer survivors; however, more research is required before adolescents can ethically be enrolled in clinical trials. As these methods advance, clinician investigators serve these patients best by (1). ensuring that the intervention does not harm the patient by delaying cancer treatment; (2). ensuring that no remnant cancer cells will be reintroduced in transplantation or fertilization; (3). preventing damaged cryopreserved oocytes from being fertilized and implanted; (4). seeking informed assent from adolescent patients and informed consent from their parents or guardians; (5). developing policies to protect the patient's future rights to her gametes; (6). developing policies addressing the disposition of gametes if the patient dies; and (7). respecting the patient by protecting her from harm while also honoring her right to self-determination.
卵母细胞和卵巢组织的采集与移植或许有一天能恢复青春期癌症幸存者的生育能力。随之而来的是关于在未来临床试验中如何尊重患者并解决伦理问题的讨论。
对青春期癌症幸存者卵母细胞和卵巢组织冷冻保存与移植中的伦理问题进行规范性分析。
规范性伦理分析。
卵母细胞和卵巢组织的采集与移植有望恢复青春期癌症幸存者的生育能力;然而,在伦理上允许青少年参与临床试验之前,还需要更多研究。随着这些方法的推进,临床研究人员能通过以下方式为这些患者提供最佳服务:(1)确保干预措施不会因延迟癌症治疗而对患者造成伤害;(2)确保移植或受精过程中不会重新引入残留癌细胞;(3)防止受损的冷冻保存卵母细胞受精和移植;(4)寻求青少年患者的知情同意和其父母或监护人的知情同意;(5)制定政策保护患者对其配子的未来权利;(6)制定政策处理患者死亡时配子的处置问题;(7)通过保护患者免受伤害同时尊重其自决权来尊重患者。
