(116) SUBJECTIVE AND GENITAL SEXUAL RESPONSE IN FEMALE BREAST CANCER SURVIVORS: RESULTS FROM A PSYCHOPHYSIOLOGY STUDY

Abstract

Abstract Introduction Sexual dysfunction is a prevalent concern affecting more than 70% of female breast cancer survivors, casting a substantial shadow on their quality of life. Beyond the physical impact of cancer and its treatments, the emotional and psychological toll of sexual dysfunction introduces additional challenges, amplifying stress levels and undermining overall well-being. Acknowledging the profound implications of sexual dysfunction in this group and the absence of therapies, there is an urgent need to delve deeper into the intricacies of its manifestations. Objective This study aimed to gather preliminary data on psychophysiological aspects of sexual function in premenopausal breast cancer patients undergoing antihormonal therapy and compare them with a healthy control group. Exploring sexual arousal in breast cancer patients may unveil potential targets for innovative treatment strategies to address sexual dysfunction in this population. Methods Participants were prescreened during a telephone interview. We included 40 premenopausal breast cancer survivors with an age range of 29 to 57 years (M = 43.5, SD = 6.36) on current hormonal treatment and 20 healthy controls with an age range of 22 to 35 (M = 27.55, SD = 3.19). Physiological measures (VPA and HRV), subjective sexual arousal (SSA) and self-reported orgasm were assessed in response to audiovisual stimuli and vibrotactile clitoral stimulation sexual stimuli in breast cancer survivors and healthy controls. Self-reported measures like the Female Sexual Function Index (FSFI), the Sexual Self-Esteem Inventory (SSEI) und the PROMIS29 were incorporated. Data were analyzed using 2-level mixed effect models. Results No significant differences in VPA scores were observed between healthy controls and breast cancer survivors. Both groups exhibited a greater genital response to clitoral vibrator use than to visual stimuli. Group differences emerged in SSA and HRV, with higher SSA and lower HRV being detected. Breast cancer survivors climaxed less frequently than healthy controls and had significantly lower self-reported sexual function. Conclusions Physiological measures of arousal in breast cancer survivors were comparable to healthy controls and only subjective arousal differed. This finding indicates that subjective arousal should be further explored as the focus of intervention and treatment methods for breast cancer patients experiencing sexual dysfunction. Our findings underscore the importance of tailored strategies that resonate with individual narratives, acknowledging the emotional intricacies of post-cancer sexual well-being. This study not only contributes to scientific knowledge but also calls for a compassionate and personalized treatment paradigm, enriching the landscape of survivorship care.
