患乳腺癌 (BC) 后，许多年轻女性对未来的生育感兴趣，有些人可能希望母乳喂养。然而，关于她们哺乳经历的信息有限。年轻女性乳腺癌研究的参与者，这是一项多中心、前瞻性队列研究，对象为 2006 年至 2016 年间诊断为 0-III 期 BC 的 ≤40 岁女性，并报告有一个或多个活产婴儿诊断后，我们对 BC 治疗后的怀孕和母乳喂养情况进行了调查，包括尝试和停止母乳喂养的原因、满意度和支持。在 143 名符合条件的女性中进行了调查，其中 115 名做出了回应，其中 94 名被纳入分析队列。 55% 的女性（94 人中的 52 人）尝试过母乳喂养。在那些没有尝试过的人中，93% 的人曾做过双侧乳房切除术（42 人中有 39 人）。在那些尝试母乳喂养的人中，69% 的人接受了肿瘤切除术和放射治疗（52 人中的 36 人），其中 83% 的人报告接受治疗的乳房没有产奶（36 人中的 30 人）。大多数人（65%，52 人中的 34 人）至少对自己的母乳喂养能力感到满意。停止母乳喂养的原因包括： 已完成计划持续时间（36%，52 人中的 19 人）；开始/恢复内分泌治疗（21%，52 人中的 11 人）；并恢复乳腺成像（8%，52 人中的 4 人）。大约一半（55 名中的 27 名）未接受双侧乳房切除术的女性回忆起在 BC 后收到过有关母乳喂养的具体信息，主要来自肿瘤学团队（59%，27 名中的 16 名）、在线资源（48%，27 名中的 13 名）或哺乳顾问（44%，27 人中的 12 人）。尽管面临挑战，但大多数尝试母乳喂养的年轻 BC 幸存者都能够对这种经历感到满意。需要特定资源来支持希望母乳喂养的 BC 幸存者。© 2024 美国癌症协会。

Following breast cancer (BC), many young women are interested in future childbearing and some may wish to breastfeed. However, limited information is available regarding their lactation experiences.Participants in the Young Women's Breast Cancer Study, a multicenter, prospective cohort study of women ≤40 years diagnosed with stage 0-III BC between 2006-2016 and who reported one or more live births following diagnosis, were surveyed about pregnancy and breastfeeding after BC treatment, including reasons for attempting and stopping breastfeeding, satisfaction, and supports.Of 143 eligible women sent a survey, 115 responded and 94 were included in the analytic cohort. Breastfeeding was attempted by 55% of women (52 of 94). Among those who had not attempted, 93% noted prior bilateral mastectomies (39 of 42). Among those who attempted breastfeeding, 69% had undergone lumpectomy and radiotherapy (36 of 52), 83% of whom reported no milk production from their treated breast (30 of 36). Most (65%, 34 of 52) were at least somewhat satisfied with their ability to breastfeed. Reasons for stopping breastfeeding included: having completed the planned duration (36%, 19 of 52); to start/resume endocrine therapy (21%, 11 of 52); and to resume breast imaging (8%, 4 of 52). Approximately half (27 of 55) of women who had not undergone bilateral mastectomies recalled receiving specific information about breastfeeding after BC, mostly from the oncology team (59%, 16 of 27), online resources (48%, 13 of 27), or a lactation consultant (44%, 12 of 27).Most young BC survivors who attempted to breastfeed were able to and were satisfied with the experience, despite challenges. Specific resources to support BC survivors who wish to breastfeed are needed.© 2024 American Cancer Society.
