Unraveling the next chapter: sexual development, body image, and sexual functioning in female BRCA carriers

Psychosexual responses to BRCA gene mutations in women of childbearing age

BACKGROUND

Diagnosis of a BRCA gene mutation presents a dilemma because life-changing medical decisions must be made to prevent breast and ovarian cancer. There is minimal evidence regarding how psychosexual functioning, psychological well-being with regard to body image and sexuality, affects the decision to have prophylactic treatment in women of childbearing age (WCBA; 18-49 years) with a BRCA gene mutation.

PURPOSE

To explore, describe, and interpret the experience of women with a BRCA mutation during the treatment and decision-making process.

METHODOLOGY

A qualitative descriptive design was used to recruit participants online through social media postings and from national and local BRCA support groups. Participants participated in semistructured interviews exploring their experience after BRCA diagnosis. Interpretive descriptive analysis was used to identify themes.

RESULTS

The purposive sample comprised 18 women aged 21-49 years. Four major themes, such as body image, sexuality, femininity, and childbearing/childrearing, were identified that influenced decisions related to the diagnosis and management of a BRCA mutation. All participants voiced that concerns regarding body image and sexuality caused hesitancy in their decision to have prophylactic surgery. Women who had undergone bilateral prophylactic mastectomy were concerned about the impact of the surgery, scarring, breast disfigurement, and the lack of sensation resulting from surgical intervention.

CONCLUSIONS

Psychosexual concerns arise from internal and external influences that significantly affect the decision to undergo prophylactic measures. Therefore, body image, sexuality, and sexual orientation should all be addressed during the decision-making process.

IMPLICATIONS

Provider communication and preparation for realistic surgical outcomes can be improved to assist WCBA throughout the decision-making process and enhance psychosexual functioning.

The impact of risk reducing bilateral salpingo-oophorectomy on sexual function in BRCA1/2 mutation carriers and women with Lynch syndrome: A systematic review and meta-analysis

OBJECTIVE

In the absence of an effective screening test, women with a high genetic predisposition for ovarian cancer are recommended to undergo risk-reducing bilateral salpingo-oophorectomy (RRBSO) once childbearing is complete. This reduces the risk of ovarian cancer by up to 96%, but can result in undesirable side effects, including menopausal symptoms and sexual dysfunction. We have performed a systematic review and meta-analysis to investigate the effect of RRBSO on sexual function in women at high risk of breast/and or ovarian cancer.

METHODS

A literature search of the AMED (Allied and complementary medicine), Embase and Medline databases was performed, using search terms including sexual function, risk reducing and oophorectomy. Results were filtered according to the PRISMA protocol. Quality assessment of studies was performed using the Newcastle-Ottawa scale. Data were pooled in meta-analysis.

RESULTS

There were 21 eligible studies, 10 of which reported sufficient data for meta-analysis. Most studies were retrospective cohort or observational studies. Fifteen of the 21 studies (71%) reported a negative impact of RRBSO on sexual function. Participant numbers ranged from 37 to 1522. Meta-analysis was performed with studies including 3201 patients. This demonstrated that RRBSO has a statistically significant negative impact on sexual function (SMD -0.63, [-0.82, -0.44], p = 0.03). There was a trend towards reduced sexual pleasure and increased discomfort but this did not reach statistical significance. There was minimal change in the frequency of sex. There was a significant increase in vaginal dryness post-RRBSO (SMD 9.25, [3.66, 14.83], p < 0.00001). There was no significant difference in sexual function between pre-menopausal and post-menopausal RRBSO. Hormone replacement therapy (HRT) did not abolish this negative impact.

CONCLUSION

Sexual function declines post RRBSO, independent of menopausal status. Comprehensive pre-operative counselling regarding anticipated menopausal and sexual symptoms is key to setting realistic patient expectations and minimising post-operative distress. Information and support regarding management of these side effects should be available to all patients.

Sexual Health in the Era of Cancer Genetic Testing: A Systematic Review

INTRODUCTION

Genetic testing for germline cancer mutations allows individuals to gain specific knowledge of their hereditary cancer risks. Although risk-reducing strategies such as increased screening, prophylactic surgeries, and chemoprevention may be potentially lifesaving, these options can also significantly impact sexual health and function.

AIM

This study overviews current challenges at the intersection of cancer genetic testing and sexual health and describes a systematic review that summarizes this evidence, identifies methodological limitations, and provides future research directions.

METHODS

Articles on the intersection of genetic testing and/or family history of cancer, cancer risk, and sexual health were searched in Medline, PsycINFO, and PsycARTICLES databases.

MAIN OUTCOME MEASURE

The main outcome measure was sexual health in women who pursued risk-reducing surgery.

RESULTS

On the basis of the inclusion criteria, 32 studies were reviewed. 31 contained empiric data from 3,367 participants; one was a conceptual study. All studies were published between 2000 and 2019. Mean ages ranged from 38 to 51.2.

CONCLUSION

Given the prevalence of sexual dysfunction after risk-reducing surgery, evidence-based interventions are needed. Furthermore, quality of life that includes sexual health, in at-risk women who pursue preventive surgery, remains an understudied aspect of cancer genetic testing. Yusufov M, Bober SL.

Interventions to improve psychosocial well-being in female BRCA-mutation carriers following risk-reducing surgery

BACKGROUND

Women who carry a pathogenic mutation in either a BRCA1 DNA repair associated or BRCA2 DNA repair associated (BRCA1 or BRCA2) gene have a high lifetime risk of developing breast and tubo-ovarian cancer. To manage this risk women may choose to undergo risk-reducing surgery to remove breast tissue, ovaries, and fallopian tubes. Surgery should increase survival, but can impact women's lives adversely at the psychological and psychosexual levels. Interventions to facilitate psychological adjustment and improve quality of life post risk-reducing surgery are needed.

OBJECTIVES

To examine psychosocial interventions in female BRCA carriers who have undergone risk-reducing surgery and to evaluate the effectiveness of such interventions on psychological adjustment and quality of life.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and Embase via Ovid, CINAHL, PsycINFO, Web of Science up to April 2019 and Scopus up to January 2018. We also handsearched abstracts of scientific meetings and other relevant publications.

SELECTION CRITERIA

We included randomised controlled trials (RCT), non-randomised studies (NRS), prospective and retrospective cohort studies and interventional studies using baseline and postintervention analyses in female BRCA carriers who have undergone risk-reducing surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed eligibility studies for inclusion in the review. We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We screened 4956 records from the searches, selecting 34 unique studies for full-text scrutiny, of which two met the inclusion criteria: one RCT and one NRS. The included studies assessed 113 female BRCA carriers who had risk-reducing surgery, but there was attrition, and outcome data were not available for all participants at final study assessments. We assessed the RCT as at a high risk of bias whilst the NRS did not have a control group. Our GRADE assessment of the studies was very low-certainty due to the paucity of data and methodological shortcomings of the studies. The primary outcome of quality of life was only measured in the RCT and that was specific to the menopause. Both studies reported on psychological distress and sexual function. Neither study measured body image, perhaps because this is most often associated with risk-reducing mastectomy rather than oophorectomy.The RCT (66 participants recruited with 48 followed to 12 months) assessed the short- and long-term effects of an eight-week mindfulness-based stress reduction (MBSR) training programme on quality of life, sexual functioning, and sexual distress in female BRCA carriers (n = 34) in a specialised family cancer clinic in the Netherlands compared to female BRCA carriers (n = 32) who received usual care. Measurements on the Menopause-Specific Quality of Life Questionnaire (MENQOL) showed some improvement at 3 and 12 months compared to the usual care group. At 3 months the mean MENQOL scores were 3.5 (95% confidence interval (CI) 3.0 to 3.9) and 3.8 (95% CI 3.3 to 4.2) for the MBSR and usual care groups respectively, whilst at 12 months the corresponding values were 3.6 (95% CI 3.1 to 4.0) and 3.9 (95% CI 3.5 to 4.4) (1 study; 48 participants followed up at 12 months). However, these results should be interpreted with caution due to the very low-certainty of the evidence, where a lower score is better. Other outcome measures on the Female Sexual Function Index and the Female Sexual Distress Scale showed no significant differences between the two groups. Our GRADE assessment of the evidence was very low-certainty due to the lack of blinding of participants and personnel, attrition bias and self-selection (as only one-third of eligible women chose to participate in the study) and serious imprecision due to the small sample size and wide 95% CI.The NRS comprised 37 female BRCA carriers selected from three Boston-area hospitals who had undergone a novel sexual health intervention following risk-reducing salpingo-oophorectomy (RRSO) without a history of tubo-ovarian cancer. The intervention consisted of targeted sexual-health education, body awareness and relaxation training, and mindfulness-based cognitive therapy strategies, followed by two sessions of tailored telephone counselling. This was a single-arm study without a control group. Our GRADE assessment of the evidence was very low-certainty, and as there was no comparison group in the included study, we could not estimate a relative effect. The study reported change in psychosexual adjustment from baseline to postintervention (median 2.3 months) using measures of Female Sexual Function Index (n = 34), which yielded change with a mean of 3.91, standard deviation (SD) 9.12, P = 0.018 (1 study, 34 participants; very low-certainty evidence). The Brief Symptom Inventory, Global Severity Index yielded a mean change of 3.92, SD 5.94, P < 0.001. The Sexual Self-Efficacy Scale yielded change with a mean of 12.14, SD 20.56, P < 0.001. The Sexual Knowledge Scale reported mean change of 1.08, SD 1.50, P < 0.001 (n = 36). Participant satisfaction was measured by questionnaire, and 100% participants reported that they enjoyed taking part in the psychoeducation group and felt "certain" or "very certain" that they had learned new skills to help them cope with the sexual side effects of RRSO.

AUTHORS' CONCLUSIONS

The effect of psychosocial interventions on quality of life and emotional well-being in female BRCA carriers who undergo risk-reducing surgery is uncertain given the very low methodological quality in the two studies included in the review. The absence of such interventions highlights the need for partnership between researchers and clinicians in this specific area to take forward the patient-reported outcomes and develop interventions to address the psychosocial issues related to risk-reducing surgery in female BRCA carriers, particularly in this new era of genomics, where testing may become more mainstream and many more women are identified as gene carriers.

Review Article: Sexuality and Risk-Reducing Salpingo-oophorectomy

INTRODUCTION

Women with familial cancer syndromes such as hereditary breast and ovarian cancer syndrome (BRCA1 and BRCA2) and Lynch syndrome are at a significantly increased risk of developing ovarian cancer and are advised to undergo prophylactic removal of their ovaries and fallopian tubes at age 35 to 40 years, after childbearing is complete.

METHODS

A comprehensive literature search of studies on risk-reducing salpingo-oophorectomy (RRSO), sexuality, and associated issues was conducted in MEDLINE databases.

RESULTS

Risk-reducing salpingo-oophorectomy can significantly impact on a woman's psychological and sexual well-being, with women wishing they had received more information about this prior to undergoing surgery. The most commonly reported sexual symptoms experienced are vaginal dryness and reduced libido. Women who are premenopausal at the time of surgery may experience a greater decline in sexual function, with menopausal hormone therapy improving but not alleviating sexual symptoms. Pharmacological treatments including testosterone patches and flibanserin are available but have limited safety data in this group.

CONCLUSIONS

Despite the high rates of sexual difficulties after RRSO, patient satisfaction with the decision to undergo surgery remains high. Preoperative counseling with women who are considering RRSO should include discussion of its potential sexual effects and the limitations of menopausal hormone therapy in managing symptoms of surgical menopause.

Preparing young people for future decision-making about cancer risk in families affected or at risk from hereditary breast cancer: A qualitative interview study

PURPOSE

Women carrying the mutated BRCA gene, have approximately an 80% life-time risk of developing breast cancer with 50% risk of their children inheriting the gene mutation. Many parents find it difficult to know when and how to disclose this information to their children and how such disclosure might affect their child's future decision-making.

METHOD

This study explored the communication of genetic risk information in families using qualitative semi-structured interviews conducted with parents, children (7-11years) and young people (12-18years) affected or at risk from a BRCA gene mutation. Thematic analysis was applied to coded transcripts producing four themes; family communication, perception of cancer risks, risk management strategies and impact of genetic risk communication in children and young people's decision making.

RESULTS

Twenty-seven individuals from 11 families took part, recruited through purposive sampling techniques. Cancer risk caused by a BRCA gene mutation induced a sense of fear in parents about their children's future. As a result, parents with hereditary breast cancer disclosed limited information about the risks associated with prophylactic surgery and/or the psychological and emotional impacts of surgery on body image. This had implications to children and young people's perceptions of prophylactic procedures, which were already influenced by cultural understandings of the 'desirable body' and increasing acceptance and proliferation cosmetic surgery.

CONCLUSION

Lack of risk management information and the acculturation of cosmetic surgery combined to limit children and young people's understanding of the impact of hereditary breast cancer; reducing their ability to actualise the physiological, psychological and emotional consequences of surgery.

Exploration of Male Attitudes on Partnerships and Sexuality with Female BRCA1/2 Mutation Carriers

Women with BRCA mutations are inundated with decisions about managing cancer risks and childbearing considerations. Decisions become more complicated when women face disclosing their mutation and risk-reduction options to a romantic partner. This study identifies the concerns and perspectives of male romantic partners regarding these unique decisions. Twenty-five male participants completed an online survey posted to cancer support group message boards. Participants reported relationship changes regarding intimacy levels (n = 9), attraction (n = 2), and communication (n = 22) after mutation disclosure. Participants whose partners had not undergone prophylactic mastectomy (n = 14) reported concerns regarding sexual relations (n = 5), post-surgical appearance (n = 2), post-surgical attraction (n = 5), and health/lifespan (n = 9). Participants did not express attitude changes toward childbearing. While mutation disclosure conversations and surgical options are concerns for many BRCA mutation carriers in relationships, male partners share these concerns. Aspects of the relationship may change, but male study participants continued to support their partners. This information can benefit female BRCA mutation carriers, their current or future partners, and genetic counselors working with this particular population.

Addressing sexual dysfunction after risk-reducing salpingo-oophorectomy: effects of a brief, psychosexual intervention

INTRODUCTION

Women at high risk for ovarian cancer due to BRCA1 or BRCA2 mutation or family history are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) after age 35 or completion of childbearing. This potentially life-saving surgery leads to premature menopause, frequently resulting in distressing and unaddressed sexual dysfunction.

AIM

To pilot a novel sexual health intervention for women with BRCA1/2 mutations who previously underwent RRSO a using a single-arm trial. Feasibility and primary outcomes including sexual dysfunction and psychological distress were assessed.

METHODS

This single-arm trial included a one-time, half-day educational session comprised of targeted sexual health education, body awareness and relaxation training, and mindfulness-based cognitive therapy strategies, followed by two sessions of tailored telephone counseling. Assessments were completed at baseline and 2 months postintervention.

MAIN OUTCOME MEASURE

Study end points include feasibility and effectiveness as reported by the participant.

RESULTS

Thirty-seven women completed baseline and postintervention assessments. At baseline, participants had a mean age of 44.4 (standard deviation [SD] = 3.9) years and mean duration of 3.8 (SD = 2.7) years since RRSO. Overall sexual functioning (P = 0.018), as well as desire (P = 0.003), arousal (P = 0.003), satisfaction (P = 0.028), and pain (P = 0.018), improved significantly. There were significant reductions in somatization (P = 0.029) and anxiety scores (P < 0.001), and, overall, for the Global Severity Index (P < 0.001) of the Brief Symptom Inventory. Sexual self-efficacy and sexual knowledge also improved significantly from baseline to postintervention (both P < 0.001). Women were highly satisfied with the intervention content and reported utilizing new skills to manage sexual dysfunction.

CONCLUSIONS

This intervention integrates elements of cognitive behavioral therapy with sexual health education to address a much-neglected problem after RRSO. Results from this promising single-arm study provide preliminary data to move toward conducting a randomized, controlled trial.

Genetic testing: when prediction generates stigmatization

Using grounded theory methodology, this study examined the experiences of six BRCA1/2 gene mutation carriers (mean age = 38.5 years). Three types of stigmatization were identified: stigmatization by anticipation, stigmatization through rejection, and stigmatization by affiliation. Participants described potential impacts on their womanhood, felt threatened by others, and revealed fears that their children would inherit their stigmatization. These findings indicate the importance of psychological support in the follow-up of such patients.

Genotype-phenotype correlations among BRCA1 4153delA and 5382insC mutation carriers from Latvia

BACKGROUND

Mutations in the high penetrance breast and ovarian cancer susceptibility gene BRCA1 account for a significant percentage of hereditary breast and ovarian cancer cases. Genotype-phenotype correlations of BRCA1 mutations located in different parts of the BRCA1 gene have been described previously; however, phenotypic differences of specific BRCA1 mutations have not yet been fully investigated. In our study, based on the analysis of a population-based series of unselected breast and ovarian cancer cases in Latvia, we show some aspects of the genotype-phenotype correlation among the BRCA1 c.4034delA (4153delA) and c.5266dupC (5382insC) founder mutation carriers.

METHODS

We investigated the prevalence of the BRCA1 founder mutations c.4034delA and c.5266dupC in a population-based series of unselected breast (n = 2546) and ovarian (n = 795) cancer cases. Among the BRCA1 mutation carriers identified in this analysis we compared the overall survival, age at diagnosis and family histories of breast and ovarian cancers.

RESULTS

We have found that the prevalence of breast and ovarian cancer cases (breast: ovarian cancer ratio) differs significantly among the carriers of the c.5266dupC and c.4034delA founder mutations (OR = 2.98, 95%CI = 1.58 to 5.62, P < 0.001). We have also found a difference in the prevalence of breast and ovarian cancer cases among the 1st and 2nd degree relatives of the c.4034delA and c.5266dupC mutation carriers. In addition, among the breast cancer cases the c.4034delA mutation has been associated with a later age of onset and worse clinical outcomes in comparison with the c.5266dupC mutation.

CONCLUSIONS

Our data suggest that the carriers of the c.4034delA and c.5266dupC founder mutations have different risks of breast and ovarian cancer development, different age of onset and prognosis of breast cancer.

Contralateral prophylactic mastectomy in breast cancer patients who test negative for BRCA mutations

BACKGROUND

Determination of BRCA1 and 2 mutation carrier status is important. Although BRCA carriers are offered bilateral mastectomy and oophorectomy, most who test negative decline. Some women choose contralateral prophylactic mastectomy (CPM) at the time of their breast cancer diagnosis despite testing negative.

METHODS

A total of 110 women with breast cancer received genetic testing before surgical treatment. Patient demographics, tumor characteristics, surgical treatment, and magnetic resonance imaging use were recorded.

RESULTS

Results revealed BRCA1/2 mutation in 33%, variant of unknown significance in 6%, and no mutation in 61% of women. In BRCA-negative women, 37% chose CPM. Marital status was significant for CPM (P = .03). Race, age, stage of presentation, and biomarker status were not associated with choice of CPM. Ninety-six percent of CPM recipients underwent breast reconstruction. Magnetic resonance imaging use did not affect CPM rates (P = .99).

CONCLUSIONS

Increased rates of CPM have been observed. In our study married women were more likely to choose CPM. We recommend genetic genotyping before surgery. These findings warrant further investigation.

Preserving the self: the process of decision making about hereditary breast cancer and ovarian cancer risk reduction

Women who carry BRCA1 or BRCA2 (BRCA1/2) gene mutations have up to an 88% lifetime risk of breast cancer and up to a 65% lifetime risk of ovarian cancer. Strategies to address these risks include cancer screening and risk-reducing surgery (i.e., mastectomy and salpingo-oophorectomy). We conducted a grounded theory study with 22 BRCA1/2 mutation-carrier women to understand how women make decisions about these risk-reducing strategies. Preserving the self was the overarching decision-making process evident in the participants' descriptions. This process was shaped by contextual conditions including the characteristics of health services, the nature of hereditary breast and ovarian cancer risk-reduction decisions, gendered roles, and the women's perceived proximity to cancer. The women engaged in five decision-making styles, and these were characterized by the use of specific decision-making approaches. These findings provide theoretical insights that could inform the provision of decisional support to BRCA1/2 carriers.

Women's constructions of the 'right time' to consider decisions about risk-reducing mastectomy and risk-reducing oophorectomy

BACKGROUND

Women who are notified they carry a BRCA1/2 mutation are presented with surgical options to reduce their risk of breast and ovarian cancer, including risk-reducing mastectomy (RRM) and risk-reducing oophorectomy (RRO). Growing evidence suggests that a sub-group of women do not make decisions about RRM and RRO immediately following genetic testing, but rather, consider these decisions years later. Women's perspectives on the timing of these decisions are not well understood. Accordingly, the purpose of this research was to describe how women construct the 'right time' to consider decisions about RRM and RRO.

METHODS

In-depth interviews were conducted with 22 BRCA1/2 carrier women and analyzed using qualitative, constant comparative methods.

RESULTS

The time that lapsed between receipt of genetic test results and receipt of RRM or RRO ranged from three months to nine years. The findings highlighted the importance of considering decisions about RRM and RRO one at a time. The women constructed the 'right time' to consider these decisions to be when: (1) decisions fit into their lives, (2) they had enough time to think about decisions, (3) they were ready emotionally to deal with the decisions and the consequences, (4) all the issues and conflicts were sorted out, (5) there were better options available, and (6) the health care system was ready for them.

CONCLUSIONS

These findings offer novel insights relevant to health care professionals who provide decision support to women considering RRM and RRO.
