Factors Impacting on Decision-Making towards Prophylactic Surgeries in BRCA Mutation Carriers and Women with Familial Predisposition

Short-term Patient-Reported Outcomes Following Bilateral Risk-Reducing Mastectomy for Patients at a High Risk for Breast Cancer: A Systematic Review

BACKGROUND

Bilateral risk-reducing mastectomies (RRMs) have been proven to decrease the risk of breast cancer in patients at high risk owing to family history or having pathogenic genetic mutations. However, few resources with consolidated data have detailed the patient experience following surgery. This systematic review features patient-reported outcomes for patients with no breast cancer history in the year after their bilateral RRM.

METHODS

The databases MEDLINE, Embase, and Scopus were used to identify studies. Studies were then evaluated by multiple authors, and their quality was assessed by using the Methodological Index for Non-Randomized Studies score.

RESULTS

Our search identified 1858 unique studies, of which 11 met our inclusion criteria. Only two of these studies included patients who did not receive postmastectomy reconstruction. The included studies were either retrospective cohort studies or prospective studies. General satisfaction with the outcome of RRM and the decision to undergo RRM was high across many of the studies, with low levels of regret. There was also a noticeable trend of improved psychosocial outcomes following RRM. For postoperative sexual well-being, body image, aesthetic satisfactions, and somatosensory function, there were a mix of positive and negative outcomes.

CONCLUSIONS

The patients who elected to manage their breast cancer risk with bilateral RRM (mostly with reconstruction) tend to be satisfied with their decision and the surgical outcomes. This may be related to decreased cancer-related anxiety. Postmastectomy psychosocial well-being tends to improve while physical health after surgery varies by patient.

Exploring the role of a multidisciplinary hereditary gynecologic oncology clinic in epithelial ovarian cancer risk-reducing surgical decision-making practices: A mixed-methods study

Individuals that have gynecologic reproductive organs with pathogenic variants in BRCA1 or BRCA2 ("BRCA-positive") have an increased risk of developing high-grade serous ovarian cancer (HGSOC). The majority of HGSOC develops in the fallopian tubes and later spreads to the ovaries and peritoneal cavity. Therefore, risk-reducing salpingo-oophorectomy (RRSO) is recommended for those who are BRCA-positive to preventatively remove their ovaries and fallopian tubes. The Hereditary Gynecology Clinic (HGC) is a provincial program in Winnipeg, Canada, that specifically targets care to the unique needs of such individuals through an interdisciplinary team of gynecological oncologists, menopause specialists, and registered nurses. A mixed-methods study design was used to explore the decision-making processes of these BRCA-positive individuals who have been recommended (or who completed) RRSO and experiences with healthcare providers at the HGC influenced this decision. Individuals who are BRCA-positive without a previous diagnosis of HGSOC and who had previously received genetic counselling were recruited from the HGC and the provincial cancer genetics program (Shared Health Program of Genetics & Metabolism). Forty-three people completed a survey and 15 participated in an in-depth interview about their experiences and decisions surrounding RRSO. Surveys were analyzed to compare scores on validated scales related to decision-making and cancer-related worry. Qualitative interviews were transcribed, coded, and analyzed using interpretive description. Participants described the complex decisions faced by those who are BRCA-positive, which are intertwined with life experiences and circumstances including age, marital status, and family disease history. Participants interpreted their HGSOC risk through a personalized "lens" of contextual factors that impacted perceptions about the practical and emotional implications of RRSO and the need for surgery. Mean scores on validated scales evaluating the HGC's impact on decisional outcomes and preparedness for decision-making about RRSO were not significant, indicating that the HGC played a supportive role, rather than helping with decision-making itself. Therefore, we present a novel framework that consolidates the various influences on decision-making and connects them to the psychological and practical implications of RRSO in the context of the HGC. Strategies for improving support, decisional outcomes, and the overall experiences of individuals who are BRCA-positive attending the HGC are also described.

"There's gonna be a lot more heartache". Coping with a BRCA1/2 alteration: A qualitative reflexive thematic analysis

BACKGROUND

This examines the coping needs of individuals with a BRCA1/2 alteration in Ireland. This study examined coping and information needs in this cohort, and was nested within a larger study in order to develop an online tool to promote positive adaptation following the identification of a BRCA1/2 alteration.

METHOD

A total of 18 participants took part in individual, semi-structured online interviews. A reflexive thematic analysis was employed to analyse data. A public and patient involvement panel of six individuals with a BRCA1/2 alteration provided input on terminology and study design.

RESULTS

Two key themes were identified. "Adjusting to a new perspective" was the first, referring to how individuals readjusted to their life after finding out about their BRCA1/2 genetic status. This theme had two subthemes (i) "emotional aspects", reflecting how participants navigated the emotive aspects of their BRCA1/2 alteration status and (ii) "relationships changing", which encompassed the ways in which interpersonal relationships were impacted by BRCA1/2. The second theme, "making sense of BRCA" had two subthemes, (i) "meaning making", depicting how participants found meaning through their BRCA1/2 alteration status, and (ii) "hope", which details the frequent reliance on hope as a means to cope with their genetic status.

CONCLUSIONS

Individuals with a BRCA1/2 alteration require specialised psychological support to assist with navigating their situation, with a focus on how to prepare for the emotional and relationship changes that the identification of BRCA1/2 alteration in the family can elicit. Providing decisional aids and informational tools may assist in meeting this need.

BRCA carriers after risk-reducing bilateral salpingo-oophorectomy: menopausal hormone therapy knowledge gaps, and the impact of physicians' recommendations

OBJECTIVE

Female carriers of BRCA1/2 gene mutations are at an increased lifetime risk for breast and ovarian cancers. They are recommended to undergo risk-reducing surgery, including bilateral salpingo-oophorectomy (RR-BSO), upon completion of childbearing. RR-BSO surgery decreases morbidity and mortality but results in early menopause. Menopausal hormone therapy (MHT) is under-utilized despite being shown as safe for carriers. We aim to evaluate the factors associated with decision-making regarding MHT use following RR-BSO in healthy BRCA mutation carriers.

METHODS

Female carriers aged <50 years who underwent RR-BSO and were followed in a multidisciplinary clinic completed online multiple-choice and free-text questionnaires.

RESULTS

A total of 142 women met the inclusion criteria and filled the questionnaire: 83 were MHT users and 59 were non-users. MHT users underwent RR-BSO earlier than non-users (40.82 ± 3.91 vs. 42.88 ± 4.34; p < 0.0001). MHT usage was positively associated with MHT explanation (odds ratio 4.318, 95% confidence interval [CI] [1.341-13.902], p = 0.014), and knowledge regarding the safety of MHT and its effects on general health (odds ratio 2.001, 95% CI [1.443-2.774], p < 0.0001). MHT users and non-users retrospectively evaluated their comprehension of RR-BSO consequences as significantly lower than before surgery (p < 0.001).

CONCLUSION

Post-RR-BSO outcomes, including the effects on women's quality of life and its possible mitigation through MHT use, need to be addressed pre surgery by healthcare providers.

Person-based co-design of a decision aid template for people with a genetic predisposition to cancer

Background

People with genetic predispositions to cancer are faced with complex health decisions about managing their risk. Decision aids can support informed, values-based decisions, alongside shared decision-making with a clinician. Whilst diagnoses of genetic predispositions to cancer are increasing, there is no scalable decision aid to support these people. This paper presents an accessible, relevant decision aid template which can be adapted for different predispositions to cancer.

Methods

The decision aid template was co-developed with 12 patients affected by cancer and informed by empirical and theoretical literature. In addition, consultations were conducted with a further 19 people with Lynch syndrome; a specific genetic predisposition to cancer. Clinical stakeholders were consulted regularly. Coulter's framework for decision aid development guided the process, and these activities were complemented by the International Patient Decision Aid Standards, and the latest evidence on communicating risk in decision aids. Programme theory was developed to hypothesise how the decision aid would support decision-making and contextual factors which could influence the process. Guiding principles co-developed with the patient panel described how the decision aid could effectively engage people.

Results

The in-depth co-design process led to the identification of five core components of an accessible decision aid template for people with a genetic predisposition to cancer: defining the decision; option grid showing implications of each option; optional further details such as icon arrays to show tailored risk and personal narratives; values clarification activity; and a summary to facilitate discussion with a clinician. Specific guidance was produced describing how to develop each component. The guiding principles identified that the decision aid template needed to promote trust, reduce distress, and be comprehensive, personally relevant and accessible in order to engage people.

Conclusion

Adopting a co-design process helped ensure that the decision aid components were relevant and accessible to the target population. The template could have widespread application through being adapted for different genetic predispositions. The exact content should be co-designed with people from diverse backgrounds with lived experience of the specific predisposition to ensure it is as useful, engaging and relevant as possible.

A qualitative reflexive thematic analysis into the experiences of being identified with a BRCA1/2 gene alteration: "So many little, little traumas could have been avoided"

Background

BRCA1/2 alterations increase females’ lifetime breast cancer risk to 40 – 90%, ovarian cancer to 10 – 60%, and males’ lifetime prostate cancer risk to ~ 10 – 25%. Psychosocial issues such as heightened distress can, therefore, occur in this population. This study aimed to explore the subjective experiences and needs of the BRCA1/2 alteration population in navigating cancer risk reduction measures.

Method

This study aimed to explore the experiences and identify the needs of 18 BRCA1/2 alteration carriers, recruited through strategic sampling. A public and patient panel (N = 6) collaborated on study development. Data were analysed using reflexive thematic analysis.

Results

Two themes were identified: (i) Healthcare Services as a Burden to Navigate, and (ii) Burden Experienced Through Interactions with Healthcare Professionals. Results indicated uncertainty regarding care pathways, alongside a lack of relevant information. Participants felt unsupported by healthcare professionals, and as though healthcare professionals often perceive them as a burden.

Conclusions

These findings suggest that the quality of interactions in healthcare systems are of relevance to the BRCA1/2 alteration population, and that uncertainty surrounding access to services and information is prevalent. The establishment of specialist hereditary cancer clinics could reduce such burden.

Rate of breast biopsy referrals in female BRCA mutation carriers aged 50 years or more: a retrospective comparative study and matched analysis

PURPOSE

To evaluate the total biopsy and positive biopsy rates in women at high risk of breast cancer compared to the general population.

METHODS

The study group consisted of 330 women with pathogenic variants (PVs) in BRCA1/2 attending the dedicated multidisciplinary breast cancer clinic of a tertiary medical center in Israel. Clinical, genetic, and biopsy data were retrieved from the central healthcare database and the medical files. Patients aged 50 years or older during follow-up were matched 1:10 to women in the general population referred for routine breast cancer screening at the same age, as recommended by international guidelines. The groups were compared for rate of biopsy studies performed and percentage of positive biopsy results. Matched analysis was performed to correct for confounders.

RESULTS

The total biopsy rate per 1000 follow-up years was 61.7 in the study group and 22.7 in the control group (p < 0.001). The corresponding positive biopsy rates per 1000 follow-up years were 26.4 and 2.0 (p < 0.001), and the positive biopsy percentages, 42.9% and 8.7% (p < 0.0001).

CONCLUSION

Women aged 50 + years with PVs in BRCA1/2 attending a dedicated clinic have a 2.7 times higher biopsy rate per 1000 follow-up years, a 13.2 times higher positive biopsy rate per 1000 follow-up years, and a 4.9 times higher positive biopsy percentage than same-aged women in the general population.

Breast Cancer Phenotype Associated With Li-Fraumeni Syndrome: A Brazilian Cohort Enriched by TP53 p.R337H Carriers

Breast cancer (BC) is the most prevalent malignancy in women with Li-Fraumeni syndrome (LFS). The literature on BC in LFS is limited due to its rarity worldwide. A TP53 founder pathogenic variant (c.1010G>A; p.R337H) is responsible for the higher prevalence of this syndrome among women of Brazilian ancestry.

Outcomes of support groups for carriers of BRCA 1/2 pathogenic variants and their relatives: a systematic review

People tested positive for BRCA1/2 face an increased risk of cancer; to help them cope with the genetic information received, support to BRCA1/2 families should be continued after testing. Nonetheless how such support should be provided has not been established yet. As a potentially valuable option is represented by support groups, the aim of this systematic review was to assess studies exploring the outcomes of support groups for BRCA1/2 carriers. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42021238416). Peer-reviewed papers published between January 1995 and February 2021 were searched for, using four databases. Among 1586 records identified, 34 papers were reviewed in full-text and eleven were included in the qualitative synthesis of the results. Three themes emerged as major focuses of support groups: risk management decisions, family dynamics and risk communication, and psychosocial functioning. Our findings show that support groups proved helpful in supporting women's decision-making on risk-reducing options. Moreover, during those interventions, BRCA1/2 carriers had the opportunity to share thoughts and feelings, and felt that mutual support through interacting with other mutation carriers help them release the emotional pressure. However, no significant impact was reported in improving family communication. Overall, a high level of satisfaction and perceived helpfulness was reported for support group. The findings suggest that support groups represent a valuable tool for improving BRCA1/2 families care.

“It was a no-brainer”: A Qualitative Study of Factors Driving Previvors’ Decision-Making when Considering Risk-Reducing Salpingectomy with Delayed Oophorectomy

•

Self-advocacy and building rapport with providers facilitated decision-making for RRS-DO-focused previvors.

•

Avoiding menopause through RRS was a key motivator for RRS-DO-focused previvors.

•

RRS-DO-focused previvors viewed RRS as a stepwise approach to risk reduction.

•

Understanding previvor priorities and experiences can help optimize shared decision-making.

Objective

Previvors are becoming more aware of the option of risk-reducing salpingectomy with delayed oophorectomy (RRS-DO) to mitigate their risk of ovarian cancer. In this qualitative study, we explored the clinical and non-clinical factors that impacted previvors’ decision-making to pursue RRS-DO as a risk reduction strategy.

Methods

Semi-structured telephone interviews were conducted with previvors and transcribed verbatim. Using ATLAS.ti® software, two primary investigators interpreted data through thematic analysis. After coding four interviews, the investigators discussed discrepancies between codes with a moderator and resolved and refined code. The investigators applied the universal codebook to all interviews and revised the codebook using an iterative approach. Examining codes within and across interviews allowed for major themes and patterns to emerge.

Results

Interviews were conducted with seventeen previvors (ages 31–46). 6 (25%) previvors had a BRCA1 mutation, 7 (41%), a BRCA2 mutation, 3 (13%), a Lynch-related mutation, and 1 (6%), other (MUTYH mutation). At the time of interview, 12 previvors (71%) were planning (6) or had undergone (6) RRS-DO, 4 (23%) were planning (1) or had undergone (3) risk reducing salpingo-oophorectomy (RRSO), and 1 (6%) was undecided. Three major themes emerged: motivating factors for selecting surgical risk reduction option, barriers complicating surgical decision-making, and facilitating factors for surgical decision-making. RRS-DO-focused previvors prioritized avoiding menopause, and they also emphasized that self-advocacy and building rapport with providers facilitated their decision-making.

Conclusion

By understanding previvors’ priorities and experiences, physicians can better partner with previvors as they navigate their ovarian cancer risk reduction journey. This will ultimately optimize shared decision-making.

COVID-19 experiences predicting high anxiety and depression among a sample of BRCA1/BRCA2-positive women in the US

During the COVID-19 pandemic, breast and ovarian cancer survivors experienced more anxiety and depression than before the pandemic. Studies have not investigated the similarities of this trend among BRCA1/2-positive women who are considered high risk for these cancers. The current study examines the impact of COVID-19 experiences on anxiety and depression in a sample of BRCA1/2-positive women in the U.S. 211 BRCA1/2-positive women from medically underserved backgrounds completed an online survey. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression for associations between COVID-19 experiences and self-reported anxiety and depression stratified by demographic factors. Overall, women who reported COVID-19 stigma or discrimination (aOR, 5.14, 95% CI [1.55, 17.0]) experienced significantly more depressive symptoms than women who did not report this experience. Racial/ethnic minority women caring for someone at home during COVID-19 were 3.70 times more likely (95% CI [1.01, 13.5]) to report high anxiety while non-Hispanic white women were less likely (aOR, 0.34, 95% CI [0.09, 1.30], p interaction = 0.011). To date, this is the first study to analyze anxiety and depression considering several COVID-19 predictors among BRCA1/2-positive women. Our findings can be used to inform future research and advise COVID-19-related mental health resources specific to these women.

COVID-19 Experiences Predicting High Anxiety and Depression Among a Sample of BRCA1/BRCA2-positive Women in the US

Purpose.

During the COVID-19 pandemic, breast and ovarian cancer survivors experienced more anxiety and depression than before the pandemic. Studies have not investigated the similarities of this trend among BRCA1/2-positive women who are considered high risk for these cancers. The current study examines the impact of COVID-19 experiences on anxiety and depression in a sample of BRCA1/2-positive women in the U.S.

Methods.

211 BRCA1/2-positive women from medically underserved backgrounds completed an online survey. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression for associations between COVID-19 experiences and self-reported anxiety and depression stratified by demographic factors.

Results.

Overall, women who reported quarantining/isolation (aOR, 0.46, 95% CI, 0.24–0.88) experienced significantly fewer depressive symptoms than women who did not report this experience. Racial/ethnic minority women caring for someone at home during COVID-19 were 3.78 times more likely (95% CI, 1.04–13.6) to report high anxiety while non-Hispanic white women were less likely (aOR, 0.36, 95% CI, 0.10–1.33, p-interaction=0.011).

Conclusions.

To date, this is the first study to analyze anxiety and depression considering several COVID-19 predictors among BRCA1/2-positive women. Our findings can be used to inform future research and advise COVID-19-related mental health resources specific to these women.
