Sexual outcomes of aromatase inhibitor therapy in women with breast cancer: time for intervention

Investigation on sexual function in young breast cancer patients during endocrine therapy: a latent class analysis

Backgrounds

The aim of this study was to investigate the sexual function status of young breast cancer patients during endocrine therapy, identify potential categories of sexual function status, and analyze the factors affecting the potential categories of sexual function status during endocrine therapy.

Methods

A cross-sectional survey was conducted on 189 young breast cancer patients who underwent postoperative adjuvant endocrine therapy in Shanghai Ruijin Hospital. The latent class analysis was used to identify potential categories of patient sexual function characteristics with respect to the FSFI sex health measures. Logistic regression analysis was used to analyze the influencing factors for the high risk latent class groups. A nomogram prognostic model were then established to identify high risk patients for female sexual dysfunction (FSD), and C-index was used to determine the prognostic accuracy.

Results

Patients were divided into a "high dysfunction-low satisfaction" group and a "low dysfunction-high satisfaction" group depending on the latent class analysis, accounting for 69.3% and 30.7%, respectively. Patients who received aromatase inhibitors (AI) combined with ovarian function suppression (OFS) treatment (p = 0.027), had poor body-image after surgery (p = 0.007), beared heavy medical economy burden(p < 0.001), and had a delayed recovery of sexual function after surgery (p = 0.001) were more likely to be classified into the "high dysfunction-low satisfaction" group, and then conducted into the nomogram. The C-index value of the nomogram for predicting FSD was 0.782.

Conclusion

The study revealed the heterogeneity of sexual function status among young breast cancer patients during endocrine therapy, which may help identify high-risk patients and provide early intervention.

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.

Sexual activity and quality of life in patients after treatment for breast and ovarian cancer

OBJECTIVE

Sexual activity (SA) and functioning (SF) are important factors influencing quality of life (QoL). Anticancer treatment can cause or promote sexual dysfunctions. In this study we analyzed the SA, SF and QoL in patients after completion of treatment for breast cancer (BC) and ovarian cancer (OC).

METHODS

In this retrospective multicenter study 396 BC patients and 93 OC patients aged between 18 and 70 years were surveyed at least 24 months after cancer diagnosis and compared to 60 healthy women. Data were collected through validated questionnaires (Sexual Activity Questionnaire, Female Sexual Function Index-d, EORTC Quality of Life Questionnaire-C30).

RESULTS

45.9% of BC patients and 56.5% of OC patients reported SA. SF and well-being of sexually active BC patients were not influenced by the type and radicality of surgery or the administration of chemotherapy. Patients who received antihormonal therapy at the time of evaluation showed a lower frequency of SA (p = 0.007), less satisfaction (p = 0.003) and more discomfort during SA (p = < 0.001) compared to healthy controls but no differences in experiencing orgasms, health status, QoL and global health status. In contrast, BC patients without antihormonal therapy showed only a higher discomfort score (p = 0.028) than healthy controls and estimated their health status and QoL significantly better than patients who received antihormonal therapy (p = 0006). In general, SA was associated with a better health status (p = 0.007), a better QoL (p = 0.004) and a better global health status (p = 0.004) in BC patients. Sexually active OC patients showed no significant differences in SF, QoL and health status compared to healthy controls.

CONCLUSIONS

Compared to healthy controls BC patients showed limitations in SF with a lower SA rate and more discomfort. Antihormonal therapy was an important factor influencing SF and well-being. Breast and OC survivors reported good physical and psychical health without differences in QoL and health status compared to controls. This might be explained by a change of perspective on life difficulties and altered priorities through a life threatening disease.

The impact of endocrine therapy on sexual dysfunction in postmenopausal women with early stage breast cancer: encouraging results from a prospective study

The goal of this project was to investigate the contentious issue of a possible effect of endocrine therapy (ET) on sexual dysfunction (SD) in postmenopausal early stage breast cancer survivors. To date, few studies have assessed sexual functioning prior to initiating ET and none have taken sexual distress into account when reporting the prevalence of ET-induced SD. We report the findings of a study on the change in SD (defined as experiencing sexual problems causing distress) during the first 6 months of ET usage. Between January 2009 and May 2011, 118 patients entered the study and 66 completed questionnaires prior to initiation of ET and after 6 months of use. Sexual functioning (SF) was evaluated with the female sexual function index while sexual distress was assessed with the female sexual distress scale (FSDS-R). Gynecological symptoms were measured with the FACT-B ES subscale. Over time, the level of gynecological symptoms increased (p < 0.001), whereas no decline in SF was observed. The percentage of women who reported experiencing at least one sexual problem (85 %) and the percentage who were sexually distressed (30 %) remained the same across time. Importantly, the change in the prevalence of SD between baseline (24 %) and 6 months (29 %) was not statistically significant. Women experiencing SD at baseline were more likely to experience SD after 6 months of ET usage (OR = 7.4, 95 % CI = 1.5-36.9) than women who had no SD prior to initiating ET. The observation that SF remained stable across time is encouraging news. However, longer follow-up and the inclusion of women who were premenopausal at diagnosis are needed to determine the potential influence of extended duration of ET (e.g., at least 5 years) on SD. Further studies, including assessing the impact of early identification of patients at risk of developing SD and timely intervention, are warranted.
