The experience of women carriers of BRCA mutations following risk-reducing surgery: A cultural perspective

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.

Breast cancer genetic mutation: Synthesis of women's experience

AIMS AND OBJECTIVES

To systematically identify and synthesise the experiences reported by women with a breast cancer mutation who do not have cancer as reported in qualitative research published between 2013 and 2020.

BACKGROUND

Women carrying a BReast CAncer (BRC) genetic mutation have an increased risk for breast and ovarian cancer. They must engage in emotional decision-making regarding risk management strategies to prevent cancer, including risk-reducing bilateral mastectomy and bilateral salpingo-oophorectomy.

DESIGN AND METHODS

The ENTREQ statement guided this review. Eight databases were systematically searched (CINAHL, Pubmed, Embase, Psychinfo [Ovid], Web of Science, Scopus, Proquest and Lenus). Synthesis was guided by "best fit" framework. The Critical Appraisal Skills Programme guided assessment of methodological limitations and confidence in the review findings was informed by GRADE-CERQual.

RESULTS

Twenty studies met the inclusion criteria for synthesis. Six themes were synthesised from the included studies (anxiety; family planning; it's a family affair; empowerment; actions; pragmatic adjustments).

CONCLUSIONS

The multidimensional experiences of women living with a BRCA1/2 mutation require an individualised response based on women's needs at their life stages. A decision coaching model adopted during consultations could support women to guide decision-making regarding cancer risk-reducing strategies.

Cost-utility analysis of risk-reducing strategies to prevent breast and ovarian cancer in BRCA-mutation carriers in Switzerland

OBJECTIVE

We aimed to identify the most cost-effective of all prophylactic measures available in Switzerland for women not yet affected by breast and ovarian cancer who tested positive for a BRCA1/2 mutation.

METHODS

Prophylactic bilateral mastectomy (PBM), salpingo-oophorectomy (PBSO), combined PBM&PBSO and chemoprevention (CP) initiated at age 40 years were compared with intensified surveillance (IS). A Markov model with a life-long time horizon was developed from the perspective of the Swiss healthcare system using mainly literature-derived data to evaluate costs, quality-adjusted life years (QALYs) and survival. Costs and QALYs were discounted by 3% per year. Robustness of the results was tested with deterministic and probabilistic sensitivity analyses.

RESULTS

All prophylactic measures were found to be cost-saving with an increase in QALYs and life years (LYs) compared to IS. PBM&PBSO were found to be most cost-effective and dominated all other strategies in women with a BRCA1 or BRCA2 mutation. Lifetime costs averaged to 141,293 EUR and 14.5 QALYs per woman with a BRCA1 mutation under IS, versus 76,639 EUR and 19.2 QALYs for PBM&PBSO. Corresponding results for IS per woman with a BRCA2 mutation were 102,245 EUR and 15.5 QALYs, versus 60,770 EUR and 19.9 QALYs for PBM&PBSO. The results were found to be robust in sensitivity analysis; no change in the dominant strategy for either BRCA-mutation was observed.

CONCLUSION

All more invasive strategies were found to increase life expectancy and quality of life of women with a BRCA1 or BRCA2 mutation and were cost-saving for the Swiss healthcare system compared to IS.

BRCA and Motherhood: A Matter of Time and Timing

The threat of cancer and the effects of risk-reducing surgery can have a significant impact on family planning and family life. In this qualitative study, we examine intersecting experiences of BRCA carrier status, subsequent risk-reducing surgery, and motherhood by analyzing in-depth interviews with 16 Jewish, Israeli mothers (ages 36-57) who underwent risk-reducing mastectomies and/or oophorectomies. Time emerged as a prism through which the BRCA motherhood experience could be viewed. In the "Findings" section, we present concepts of BRCA time and maternal time through three subthemes: (a) objective and subjective fertility clocks and BRCA: the child who won't be born; (b) synchronizing the clocks: the "correct" tempo and chronology; and (c) back to the future: intergenerational coalescence of time. We discuss the notions of time and existential health threats and subjective time in the primary mother-infant relational system within the context of the cultural ideal of the "motherhood myth."
