DESCRIPTION (provided by applicant): Infertility and premature ovarian senescence are life-changing consequences of cancer in young women. Yet, the reproductive window after cancer treatment in young adult cancer survivors (YA survivors) is not known. In light of growing numbers of YA survivors and emergence of promising interventions on fertility after cancer treatment, there is a clear need to identify and categorize patterns of ovarian aging after cancer and the clinical profiles associated with them to assist in patient counseling and decision making. 1000 female YA survivors who are between ages 18-35 will be enrolled at varying durations after cancer treatment and followed for 18 months. First, the study will test the hypothesis that patterns of anti-mullerian hormone (AMH), follicle stimulating hormone (FSH) and estradiol (E2) after cancer treatment will differ among three broad treatment toxicity groups. Ovarian function biomarker levels will be measured from serial self-collected dried blood spot (DBS) samples in each participant. Data from the entire cohort will then be modeled by time after cancer treatment, and patterns (including time to peak, duration at peak and time to decline of ovarian function) will be compared among minimal, moderate and severe treatment toxicity groups. The aim will demonstrate that these biomarkers can depict differential durations of the reproductive window. Second, spurred by exciting preliminary data, the study will test the hypothesis that disproportionate psychological distress experienced by this population is associated with hypothalamic suppression of ovarian function. The aim will determine the association between distress (measured by patient-reported symptoms and salivary cortisol) and luteinizing hormone (LH), FSH, E2 and AMH. Hypothalamic-pituitary-ovarian axis suppression has never been studied in the context of cancer, and discovery of an association between distress and ovarian function would be critical to future intervention studies on distress to modify reproductive health outcomes. Third, the study will generate clinical risk profiles for te window of ovarian function for the moderate toxicity group, which encompasses the majority of YA survivors. Due to heterogeneity, there are no data on predicting variability in the course of ovarian aging within this group. This aim will identify subpopulations in patterns of ovarian function within the moderate toxicity group, followed by the clinical factors that are associated with them. Building on the PI's K23 data, this proposal directly responds to priorities of the NICHD Fertility Preservation Program to develop biomarkers and clinical parameters to better predict gonadal reserve, and optimize and expand options for fertility preservation. The significance lies in estimating the reproductive lifespan in the context of cancer in order to guid patient counseling, individualize risks and preserve opportunities for biologic parenthood. Through innovative use of social media for recruitment and non-clinic- based, minimally invasive DBS and saliva collection for biosample accrual, the proposal overcomes longstanding, critical barriers to studying young adults with cancer. 1

描述(由申请人提供)：不孕不育和卵巢早衰是年轻女性癌症改变一生的后果。然而，年轻的成年癌症幸存者(YA幸存者)在癌症治疗后的生殖窗口尚不清楚。鉴于YA幸存者的数量不断增加，以及癌症治疗后出现了有希望的生育干预措施，显然有必要确定和分类癌症后卵巢老化的模式和与其相关的临床特征，以帮助患者咨询和决策。1000名年龄在18-35岁之间的女性YA幸存者将在癌症治疗后的不同时间内入选，并进行为期18个月的跟踪调查。首先，这项研究将检验这样一个假设，即癌症治疗后抗苗勒氏激素(AMH)、卵泡刺激素(FSH)和雌二醇(E2)的模式将在三个广泛的治疗毒性组中有所不同。卵巢功能生物标记物水平将从每个参与者的连续自我收集的干血斑(DBS)样本中测量。然后，将根据癌症治疗后的时间对整个队列的数据进行建模，并将在轻度、中度和重度治疗毒性组之间比较模式(包括卵巢功能达到峰值的时间、峰值持续时间和下降时间)。目的将证明这些生物标志物可以描述生殖窗口的不同持续时间。其次，在令人兴奋的初步数据的刺激下，这项研究将检验这一假设，即这一人群经历的不成比例的心理痛苦与下丘脑对卵巢功能的抑制有关。目的是确定痛苦(通过患者报告的症状和唾液皮质醇来衡量)与黄体生成素(LH)、卵泡刺激素(FSH)、雌二醇(E2)和黄体生成素(AMH)之间的联系。下丘脑-垂体-卵巢轴抑制从来没有在癌症的背景下被研究过，发现痛苦和卵巢功能之间的联系对于未来关于痛苦的干预研究以改变生殖健康结果至关重要。第三，这项研究将为包括大多数YA幸存者在内的中度毒性组生成卵巢功能TE窗口的临床风险概况。由于异质性，在这一组中没有预测卵巢老化过程中的变异性的数据。这一目标将确定中度毒性组内卵巢功能模式的亚群，以及与它们相关的临床因素。基于PI的K23数据，这项建议直接回应了NICHD生育力保存计划的优先事项，开发生物标记物和临床参数以更好地预测性腺储备，并优化和扩大生育力保存的选择。其意义在于在癌症的背景下估计生殖寿命，以指导患者咨询，个性化风险并保留为生物父母的机会。通过创新地使用社交媒体进行招募，以及非临床、微创的DBS和唾液收集以获取生物样本，该提案克服了长期存在的关键障碍，无法研究患有癌症的年轻人。1
