背景：完成積極治療後的乳癌婦女，性生活問題持續延長至存活期。然而，國內極少研究探究乳癌婦女與伴侶於積極治療完成後，性生活復原情況、不同層面的性生活問題及其影響因素。目的：了解乳癌存活婦女性生活現況及性生活的影響因素。方法：採橫斷相關性研究設計，以方便取樣，於南部某一所醫院癌症中心，招募完成積極治療且未復發之136位乳癌婦女參與。以結構式問卷收集婦女人口學、疾病治療、身體外觀及不同層面性生活；包括性困擾、性表現、性親密及性自尊等相關資料，進而了解影響不同層面性生活之影響因素，並以複迴歸檢測影響整體性生活及其不同層面之可能因素。結果：136位參與者有16.1%乳癌婦女尚未恢復性生活，恢復性生活者亦經歷不同性生活困擾。治療種類對性生活不同層面的影響有限，且不同層面性生活之影響因素有差異。預測不同層面性生活的因素包括：年齡、擔心復發的程度、裸體時對胸部外觀滿意度、及罹病前性生活滿意度；術後伴侶外觀滿意度未形成重要影響因素。結論/實務應用：影響乳癌存活婦女性生活的可能因素為年齡、擔心復發、婦女對自我身體外觀的評價、罹病前性生活滿意度。醫療照護人員不能忽略年長者的性生活問題，且可藉由降低婦女對復發的擔心、協助婦女接受手術後對身體的認同，同時提供緩解性行為過程不適的方法來提升存活婦女的性生活關係。

Background: Women who complete breast cancer surgery, chemotherapy, and hormone therapy may experience sexual disturbances that extend beyond the acute phase of treatment. There is a relative dearth of studies examining different aspects of the sexual life and the related factors among breast cancer survivors. Purpose: This study assesses sexual life and the factors related to different aspects of the sexual life of breast cancer survivors. Method: A cross‐sectional correlation design was used. A total of 136 women who had completed aggressive treatment and who had not experienced recurrence were recruited from a hospital cancer registry in south of Taiwan. After agreeing to participate and signing informed consent, the participants were given questionnaires that included demographic and treatment‐related information, an evaluation of their physical appearance, and relationship and sexuality scales that addressed topics including sexual difficulties, sexual performance, sexual intimacy, and sexual self‐esteem aspects. The data were analyzed using multiple regressions in order to understand the factors related to their sexual life and examine the significant predictors of sexual life in breast cancer survivors. Results: Among the 136 women who participated in this study, 16.1% reported they had not yet recovered their pre‐diagnosis sexual life. Of those who had, all experienced some type of sexual disturbance. Treatmentrelated factors had limited effects on the sexual life of the women, and the factors related to different aspects of their sexual life varied. The significant predictors of overall sexual life included age, breast satisfaction when naked, and sexual satisfaction prior to diagnosis. However, partner’s satisfaction was not an important factor influencing women’s sexual life. Conclusions / Implications for Practice: The findings of this study suggest that age, fear of recurrence, and breast satisfaction when naked, and sexual satisfaction before diagnosis are variables that significantly influence the sexual life of breast cancer survivors. In order to improve the sexual life and intimate relationships of women with breast cancer, health care professionals should focus greater attention on the sexual problems of older women, help survivors decrease their fear of cancer recurrence and improve their self‐identify about their post‐surgery bodies, and provide survivors with information about relieving discomfort during sexual activity.
