Sexual Function Post-Breast Cancer

Machine Learning-Based Predictive Model for Mortality in Female Breast Cancer Patients Considering Lifestyle Factors

Purpose

To construct a free and accurate breast cancer mortality prediction tool by incorporating lifestyle factors, aiming to assist healthcare professionals in making informed decisions.

Patients and Methods

In this retrospective study, we utilized a ten-year follow-up dataset of female breast cancer patients from a major Chinese hospital and included 1,390 female breast cancer patients with a 7% (96) mortality rate. We employed six machine learning algorithms (ridge regression, k-nearest neighbors, neural network, random forest, support vector machine, and extreme gradient boosting) to construct a mortality prediction model for breast cancer.

Results

This model incorporated significant lifestyle factors, such as postsurgery sexual activity, use of totally implantable venous access ports, and prosthetic breast wear, which were identified as independent protective factors. Meanwhile, ten-fold cross-validation demonstrated the superiority of the random forest model (average AUC = 0.918; 1-year AUC = 0.914, 2-year AUC = 0.867, 3-year AUC = 0.883). External validation further supported the model's robustness (average AUC = 0.782; 1-year AUC = 0.809, 2-year AUC = 0.785, 3-year AUC = 0.893). Additionally, a free and user-friendly web tool was developed using the Shiny framework to facilitate easy access to the model.

Conclusion

Our breast cancer mortality prediction model is free and accurate, providing healthcare professionals with valuable information to support their clinical decisions and potentially promoting healthier lifestyles for breast cancer patients.

Assessment of sexual function in postmenopausal breast cancer survivors

Background

Breast cancer (BC) is considered a risk factor for sexual dysfunction, which may be associated with the diagnosis itself or with oncological treatments. However, sexual dysfunction often remains underdiagnosed and unaddressed among BC survivors.

Aim

The study sought to evaluate the sexual function of postmenopausal BC survivors compared with postmenopausal women without BC.

Methods

This case-control study included 178 postmenopausal BC survivors (stages I-III), 45 to 70 years of age, with amenorrhea for ≥12 months and sexually active. They were compared with 178 women without BC, matched (±2 years) for age and time since menopause in a 1:1 ratio. Sexual function was evaluated using the Female Sexual Function Index (FSFI), which consists of 6 domains (desire, arousal, lubrication, orgasm, satisfaction, and pain), with a total score ≤26.5 indicating risk of sexual dysfunction. Statistical analysis included Student's t test, chi-square test, and logistic regression (odds ratio [OR]).

Outcomes

Evaluation of sexual function in postmenopausal women treated for BC.

Results

Postmenopausal BC survivors showed poorer sexual function in the desire domain (P = .002). No significant differences were observed between groups in the other FSFI domains and total score (P > .05). Postmenopausal BC survivors had a higher prevalence of risk of sexual dysfunction (64.6% with a total score ≤26.5) compared with the control group (51.6%) (P = .010). Adjusted risk analysis for age and time since menopause revealed a higher risk of sexual dysfunction in BC survivors compared with women without cancer (OR, 1.98; 95% confidence interval, 1.29-2.96; P = .007). Among BC survivors, the use of hormone therapy was associated with a higher risk of sexual dysfunction (OR, 3.46; 95% confidence interval, 1.59-7.51; P = .002).

Clinical Implications

Postmenopausal BC survivors should be regularly assessed before and throughout treatment to enable the early detection and diagnosis of sexual dysfunction.

Strength and Limitations

The main strength is that this study might contribute to a better understanding of sexual function in postmenopausal BC survivors compared with women without BC. The main limitation is that while the FSFI is a valid and reliable tool for the evaluation of female sexual function, it does not allow a comprehensive diagnosis of sexual dysfunction, as it is not applicable to partners.

Conclusion

Compared with postmenopausal women without BC, postmenopausal BC survivors face a higher risk of sexual dysfunction, especially when treated with adjuvant hormone therapy.

Sexual dysfunctions in breast cancer patients: evidence in context

INTRODUCTION

In breast cancer patients, endocrine therapy may exert a negative impact on sexual functioning in both genders, with potentially relevant consequences concerning quality of life and treatment adherence. The availability of effective interventions to maintain and/or restore sexual health in breast cancer patients is a key issue to a research agenda.

OBJECTIVES

To summarize and critically discuss the most updated and qualitatively relevant literature on the therapeutic approach to sexual impairment in breast cancer patients, with a focus on patients treated with endocrine therapy.

METHODS

We searched PubMed from its inception to February 2022 for observational and intervention trials including participants with sexual dysfunctions. We were particularly interested in studies of breast cancer patients with sexual dysfunctions while undergoing endocrine therapy. We developed a search strategy with the aim of maximizing the number of articles considered for screening and potential inclusion.

RESULTS

Forty-five studies were selected: 3 observational and 42 intervention studies. Thirty-five studies were exclusively focused on female breast cancer populations. We could not identify studies exclusively focused on or also including male breast cancer patients. Overall, in female patients, the available armamentarium encompasses vaginal lubricants, moisturizers, estrogens, dehydroepiandrosterone, CO2 laser, ospemifene, and counseling. None of these interventions has been demonstrated to completely solve sexual dysfunctions when singularly considered. More favorable outcomes have come from the combination of different therapies.

CONCLUSION

In female breast cancer, future research is oriented toward the gain of evidence on combined therapies and long-term data on safety issues on the most promising interventions. The lack of evidence on sexual disturbances in male breast cancer patients remains a major concern.

Diagnosis, causes, and treatment of dyspareunia in postmenopausal women

IMPORTANCE AND OBJECTIVES

Evaluation and treatment of dyspareunia remains a significant unmet need despite the availability of safe and effective treatments. The objectives of this review are to consider evaluation techniques, the medical causes, and treatment options for dyspareunia in postmenopausal women.

METHODS

This narrative review used PubMed to search for English-language articles related to postmenopausal dyspareunia. Search terms included, but were not limited to, dyspareunia, genitourinary syndrome of menopause, sexual dysfunction, postmenopausal dyspareunia, posthysterectomy dyspareunia, and postcancer dyspareunia.

FINDINGS

Many postmenopausal women with dyspareunia do not discuss their symptoms with their physicians. Healthcare clinicians should broach the topic of dyspareunia with their patients using oral or written questionnaires. In addition to a thorough medical history and physical examination, various tools can be used as further assessments, including vaginal pH, vaginal dilators, imaging, vulvar biopsy, vulvoscopy and photography, the cotton swab test, sexually transmitted infection screening, and vaginitis testing. Although dyspareunia in postmenopausal women is often due to the genitourinary syndrome of menopause, other conditions can also cause dyspareunia, including hypertonic pelvic floor, hysterectomy, cancer treatment, lichen conditions, vulvar cancer, vestibulodynia, and pelvic organ prolapse. Some of the treatments discussed include lubricants, moisturizers, vaginal estrogen, ospemifene, dehydroepiandrosterone, local testosterone therapy, cannabidiol, and fractional CO2 laser treatments. In some cases, dyspareunia may need to be specifically addressed by pelvic floor physical or sex therapists.

CONCLUSIONS

Dyspareunia is a common issue in postmenopausal women, which remains largely untreated. Women with dyspareunia require a thorough history, targeted physical examination, and coordination of multiple disciplines including medical clinicians, pelvic floor physical therapists, and sex therapists.

Sexual Perception in Spanish Female Breast Cancer Survivors. Cross-Sectional Survey

BACKGROUND

The aim was to assess sexual perception in female breast cancer survivors and establish if women presenting with sexual dysfunctions symptoms receive pelvic floor physiotherapy or request information on treatment.

METHODS

Cross-sectional survey carried out between January and March 2021. An online survey designed by the authors was structured in 3 dimensions: demographic and anthropometric data, medical data and sexual perception data. An open format survey with 23 questions available to any website visitor. The survey followed the CHERRIES guidelines. The study included 130 women who fulfilled the inclusion criteria.

RESULTS

The presence of pain during sexual activity was reported in 56.92% of cases. Specifically, 40.8% reported superficial dyspareunia, which is most commonly expressed by women as a "stinging pain." Surprisingly, only 4.6% of the women had received any type of pelvic floor physiotherapy treatment or had sought information.

CONCLUSIONS

Women breast cancer survivors have a negative perception of their sexuality. In addition, there is a lack of knowledge about the role of physiotherapy in sexual dysfunction, and only a small percentage of women received pelvic floor treatment or information to address their sexual dysfunction.

Long-Term Effects of Breast Cancer Therapy and Care: Calm after the Storm?

Breast cancer is still a lethal disease and the leading cause of death in women, undermining patients' survival and quality of life. Modern techniques of surgery and radiotherapy allow for the obtaining of good results in terms of survival, however they cause long-term side effects that persist over time, such as lymphedema and neuropathy. Similarly, the advent of new therapies such as endocrine therapy revolutionized breast cancer outcomes, but side effects are still present even in years of follow-up after cure. Besides the side effects of medical and surgical therapy, breast cancer is a real disruption in patients' lives considering quality of life-related aspects such as the distortion of body image, the psychological consequences of the diagnosis, and the impact on family dynamics. Therefore, the doctor-patient relationship is central to providing the best support both during treatment and afterwards. The aim of this review is to summarize the consequences of medical and surgical treatment on breast cancer patients and to emphasize the importance of early prevention of side effects to improve patients' quality of life.

Sexual Health after a Breast Cancer Diagnosis: Addressing a Forgotten Aspect of Survivorship

Breast cancer is the most common cancer in women. The life expectancy after a breast cancer diagnosis is improving steadily, leaving many more persons with the long-term consequences of treatment. Sexual problems are a common concern for breast cancer survivors yet remain overlooked in both the clinical setting and the research literature. Factors that contribute to sexual health concerns in breast cancer survivors are biopsychosocial, as are the barriers to addressing and treating these health concerns. Sexual health needs and treatment may vary by anatomy and gender. Multidisciplinary management may comprise lifestyle modifications, medications, sexual health aids such as vibrators, counseling, and referrals to pelvic health physical therapy and specialty care. In this article, we review the contributing factors, screening, and management of sexual difficulties in cisgender female breast cancer survivors. More information is needed to better address the sexual health of breast cancer survivors whose sexual/gender identity differs from that of cisgender women.

Sexual activity and functioning in long-term breast cancer survivors; exploring associated factors in a nationwide survey

PURPOSE

Sexual health is a key quality of life issue. Knowledge concerning sexual health in long-term breast cancer survivors (BCSs) is limited. Within a nationwide sample, we aimed to assess the prevalence of sexual inactivity and to explore factors associated with sexual inactivity and reduced sexual functioning among long-term BCSs.

METHODS

Long-term BCSs aged 20-65 years when diagnosed with early-stage breast cancer in 2011-2012 were identified by the Cancer Registry of Norway in 2019 (n = 2803) and invited to participate in a nationwide survey. Sexual health was measured using the multidimensional Sexual Activity Questionnaire. Factors associated with sexual inactivity and reduced sexual functioning were explored using multivariable logistic- and linear regression analyses with adjustments for relevant sociodemographic, health-, and cancer-related variables.

RESULTS

The final sample consisted of 1307 BCSs with a mean age of 52 years at diagnosis. Fifty-two percent of the BCSs were sexually inactive. Lack of interest was the most common reason for sexual inactivity. Treatment with aromatase inhibitor (OR 1.73, 95% CI 1.23, 2.43) and poor body image (OR 0.99, 95% CI 0.99, 0.995) were associated with sexual inactivity. Among sexually active BCSs, depression (B - 1.04, 95% CI - 2.10, - 0.02) and physical inactivity (B - 0.61, 95% CI - 1.21, - 0.02) were inversely related to sexual pleasure. Treatment with aromatase inhibitor (B 0.61, 95% CI 0.20, 1.01), sleep problems (B 0.37, 95% CI 0.04, 0.70), breast symptoms (B 0.01, 95% CI 0.003, 0.02), and chronic fatigue (B 0.43, 95% CI 0.05, 0.81) were associated with sexual discomfort. Chemotherapy (OR 1.91, 95% CI 1.23, 2.97), current endocrine treatment (OR 1.98, 95% CI 1.21, 3.25), and poor body image (OR 0.98, 95% CI 0.98, 0.99) were associated with less sexual activity at present compared to before breast cancer.

CONCLUSION

Treatment with aromatase inhibitor seems to affect sexual health even beyond discontinuation. Several common late effects were associated with sexual inactivity and reduced sexual functioning. To identify BCSs at risk of sexual dysfunction, special attention should be paid to patients treated with aromatase inhibitor or suffering from these late effects.

Menopause and female sexual dysfunctions (FSDs)

Biological and psycho-relational factors contribute equally to the development of sexual symptoms and associated distress, a key element to diagnose female sexual dysfunctions (FSDs) in menopausal women. Consultation at midlife represents an optimal time to discuss sexual life, and healthcare providers (HCPs) have to be proactive in rising the conversation, as patients may not report their sexual concerns spontaneously. An accurate sexual history is essential to characterize the primary symptom, determine the impact on patient's quality of life and identify risk and precipitating factors. Among FSDs, hypoactive sexual desire disorder (HSDD) is very frequent at midlife together with genitourinary syndrome of menopause (GSM), a chronic condition negatively affecting the full sexual response. A multidimensional approach targeted to the patient's characteristics, goals and expectations is mandatory and should start from educative counselling and correction of modifiable risk factors. When specific treatments are required, they should include non-pharmacological and pharmacological options, often prescribed in combination to address concomitantly the biological and psychosocial components of FSDs.

Impact of mindfulness-based stress reduction on female sexual function and mental health in patients with breast cancer

Purpose

There have been few studies using mindfulness-based stress reduction (MBSR) to improve sexual function in Asian women with breast cancer. This study aimed to evaluate the impact of mindfulness intervention on female sexual function, mental health, and quality of life in patients with breast cancer.

Methods

Fifty-one women with breast cancer were allocated into 6-week MBSR (n=26) sessions or usual care (n=25), without differences in group characteristics. The research tools included the Female Sexual Function Index (FSFI), the Depression Anxiety Stress Scales-21 (DASS-21), and the EuroQol instrument (EQ-5D). The Greene Climacteric Scale (GCS) was used to verify the foregoing scale. The effects of MBSR were evaluated by the differences between the post- and pre-intervention scores in each scale. Statistical analyses consisted of the descriptive dataset and Mann-Whitney ranked-pairs test.

Results

Although MBSR did not significantly improve sexual desire and depression in patients with breast cancer, MBSR could improve parts of female sexual function [i.e., Δarousal: 5.73 vs. -5.96, Δlubrication: 3.35 vs. -3.48, and Δsatisfaction: 8.48 vs. 1.76; all p <.005], with a range from small to medium effect sizes. A significantly benefits were found on mental health [Δanxiety: -10.92 vs.11.36 and Δstress: -10.96 vs.11.40; both p <.001], with large effect sizes, ranging from 0.75 to 0.87.

Conclusion

Our study revealed that MBSR can improve female sexual function and mental health except for sexual desire and depression in women with breast cancer. Medical staff can incorporate MBSR into clinical health education for patients with breast cancer to promote their overall quality of life.

Sexuality, pelvic floor/vaginal health and contraception at menopause

A multitude of biopsychosocial factors influences sexual health at midlife, a common concern in daily practice along with vaginal and pelvic health. Health-care providers (HCPs) need to be proactive in dealing with possible symptoms because in most cases early management prevents distress and improves quality of life. Female sexual dysfunctions (FSDs) may have a complex etiology but sexual history is not difficult implementing basic knowledge of risk factors and some skills helping women to cope with hormonal and age-related changes. This work summarizes key points to approach sexual symptoms in midlife women, providing principles to diagnose and manage hypoactive sexual desire disorder (HSDD) and genitourinary syndrome of menopause (GSM)/vulvovaginal atrophy (VVA), as well as manage contraceptive needs.

Sex Hormones Related Ocular Dryness in Breast Cancer Women

Background: Dry eye syndrome (DES) is strictly connected to systemic and topical sex hormones. Breast cancer treatment, the subsequent hormonal therapy, the subsequent hyperandrogenism and the early sudden menopause, may be responsible for ocular surface system failure and its clinical manifestation as dry eye disease. This local dryness is part of the breast cancer iatrogenic dryness, which affects overall mucosal tissue in the fragile population of those with breast cancer. Methods: A literature review regarding the role of sex hormone changes and systemic hormonal replacement treatments (SHRT) in DES available on PubMed and Web of Science was made without any restriction of language. Results: Androgens exert their role on the ocular surface supporting meibomian gland function and exerting a pro-sebaceous effect. Estrogen seems to show a pro/inflammatory role on the ocular surface, while SHRT effects on dry eye are still not well defined, determining apparently contradictory consequences on the ocular surface homeostasis. The role of sex hormones on dry eye pathogenesis is most likely the result of a strict crosstalk between the protective androgens effects and the androgen-modulating effects of estrogens on the meibomian glands. Conclusions: Patients with a pathological or iatrogenic hormonal imbalance, such as in the case of breast cancer, should be assessed for dry eye disease, as well as systemic dryness, in order to restore their social and personal quality of life.

The 2020 genitourinary syndrome of menopause position statement of The North American Menopause Society

OBJECTIVE

To update and expand the 2013 position statement of The North American Menopause Society (NAMS) on the management of the genitourinary syndrome of menopause (GSM), of which symptomatic vulvovaginal atrophy (VVA) is a component.

METHODS

A Panel of acknowledged experts in the field of genitourinary health reviewed the literature to evaluate new evidence on vaginal hormone therapies as well as on other management options available or in development for GSM. A search of PubMed was conducted identifying medical literature on VVA and GSM published since the 2013 position statement on the role of pharmacologic and nonpharmacologic treatments for VVA in postmenopausal women. The Panel revised and added recommendations on the basis of current evidence. The Panel's conclusions and recommendations were reviewed and approved by the NAMS Board of Trustees.

RESULTS

Genitourinary syndrome of menopause affects approximately 27% to 84% of postmenopausal women and can significantly impair health, sexual function, and quality of life. Genitourinary syndrome of menopause is likely underdiagnosed and undertreated. In most cases, symptoms can be effectively managed. A number of over-the-counter and government-approved prescription therapies available in the United States and Canada demonstrate effectiveness, depending on the severity of symptoms. These include vaginal lubricants and moisturizers, vaginal estrogens and dehydroepiandrosterone (DHEA), systemic hormone therapy, and the estrogen agonist/antagonist ospemifene. Long-term studies on the endometrial safety of vaginal estrogen, vaginal DHEA, and ospemifene are lacking. There are insufficient placebo-controlled trials of energy-based therapies, including laser, to draw conclusions on efficacy and safety or to make treatment recommendations.

CONCLUSIONS

Clinicians can resolve many distressing genitourinary symptoms and improve sexual health and the quality of life of postmenopausal women by educating women about, diagnosing, and appropriately managing GSM. Choice of therapy depends on the severity of symptoms, the effectiveness and safety of treatments for the individual patient, and patient preference. Nonhormone therapies available without a prescription provide sufficient relief for most women with mild symptoms. Low-dose vaginal estrogens, vaginal DHEA, systemic estrogen therapy, and ospemifene are effective treatments for moderate to severe GSM. When low-dose vaginal estrogen or DHEA or ospemifene is administered, a progestogen is not indicated; however, endometrial safety has not been studied in clinical trials beyond 1 year. There are insufficient data at present to confirm the safety of vaginal estrogen or DHEA or ospemifene in women with breast cancer; management of GSM should consider the woman's needs and the recommendations of her oncologist.

Effects of local laser treatment on vulvovaginal atrophy among women with breast cancer: a prospective study with long-term follow-up

PURPOSE

Women with breast cancer (BC) often suffer from severe vulvovaginal atrophy (VVA) which ultimately leads to poor sexual and urinary quality of life. We conducted a prospective study among women with BC and VVA, in order to evaluate the long-term effect of laser therapy on VVA.

METHODS

Women with BC and VVA were proposed to have fractional microablative CO₂ laser therapy (MonaLisaTouch®, DEKA) once per month for 3 months. Efficacy of laser therapy was assessed at baseline, 6 months and 18 months after treatment, using Female Sexual Function Index (FSFI) score, Ditrovie score and vaginal pH. A pap smear was also performed and the epithelial maturation pattern was noted. Paired statistical tests were used to compare results between baseline, 6 months and 18 months.

RESULTS

46 women with BC (median age [interquartile range] 56.5 years [47.0 - 59.4]) were included between May and October 2018. PH level slightly decreased over time (mean Δ at 18 months -0.3, SD = 0.7, p = 0.02) whereas maturation pattern on pap smear did not change. Sexual quality of life was significantly improved at 6 months and 18 months (mean Δ at 6 months 8.3, SD = 6.2 (p < 0.0001) and mean Δ at 18 months 4.3, SD = 8.4 (p = 0.01)). Ditrovie total score improved at 6 months (mean Δ -1.2, SD = 2.7, p = 0.01) but returned to baseline afterwards. Side effects were very mild. Three women developed low (2)- and high (1)-grade HPV-linked cervical lesions during follow-up.

CONCLUSION

Among women with BC, fractional microablative CO₂ laser is effective on the long term on VVA symptoms and gynaecological quality of life.

Perils of prolonged ovarian suppression and hypoestrogenism in the treatment of breast cancer: Is the risk of treatment worse than the risk of recurrence?

Premenopausal breast cancer is usually estrogen receptor positive, and hence, prolonged ovarian suppression by medical or surgical means to prevent recurrence has become standard of management to improve disease-free survival. Ten-year adjuvant tamoxifen therapy is associated with 3.5% fewer recurrences compared to five years. The SOFT trial demonstrated small but statistically significant incremental improvements in long-term disease-free survival by the addition of gonadotropin-releasing hormone analog treatment (triptorelin) to an aromatase inhibitor (exemestane). Profound hypoestrogenism in the premenopausal age group may not be well tolerated due to a host of bothersome side effects (primarily vasomotor symptoms, musculoskeletal complaints, genitourinary syndrome of menopause, and mood disorders). Prolonged hypoestrogenism in younger women is associated with premature development of cardiovascular disease, bone loss, cognitive decline, and all-cause mortality. This paper explores multi-system consequences of prolonged hypoestrogenism in premenopausal women derived from studies of women with and without breast cancer. Pretreatment counseling in estrogen receptor positive breast cancer should emphasize the benefit of prolonged estrogen suppression on breast cancer recurrence and established risks of lifelong hypoestrogenism on quality of life and all-cause mortality. Future genomic research may help identify the best candidates for extended ovarian suppression to avoid treating many women when only a minority benefit.

Sexual quality of life in men and women after cancer

More than 60% of people treated for cancer have long-term sexual dysfunction. However, fewer than 25% of those with sexual problems get help from a health professional. Although cancer-related sexual problems usually begin with physiological damage from cancer treatment, a patient's coping skills and the quality of the sexual relationship are crucial in sexual rehabilitation. Barriers to care for people treated for cancer include a lack of discussion with the oncology team. In repeated surveys, fewer than half of patients recall discussing sex or fertility with their care providers, even during informed consent. Practice guidelines on sexuality and cancer were published in 2017 by the American Society for Clinical Oncology (ASCO) and the National Comprehensive Cancer Network (NCCN). Both agree the following: The oncology team should initiate discussions of sexuality and cancer during treatment planning and at follow-up visits. Psychosocial and medical assessment should take place when a concern or problem is identified. Referrals should be offered for multidisciplinary treatment, since sexual problems frequently have both psychosocial and physiological causes.This article describes a system of care that can meet the guidelines while providing sustainable revenue.
