Risk-management decision-making data from a community-based sample of racially diverse women at high risk of breast cancer: rationale, methods, and sample characteristics of the Daughter Sister Mother Project survey

BACKGROUND

To understand the dynamics that limit use of risk-management options by women at high risk of breast cancer, there is a critical need for research that focuses on patient perspectives. Prior research has left important gaps: exclusion of high-risk women not in risk-related clinical care, exclusion of non-white populations, and lack of attention to the decision-making processes that underlie risk-management choices. Our objective was to create a more inclusive dataset to facilitate research to address disparities related to decision making for breast cancer risk management.

METHODS

The Daughter Sister Mother Project survey collects comprehensive information about the experiences of women at high risk of breast cancer. We collected novel measures of feelings about and reactions to cancer screenings; knowledge, barriers, and facilitators of risk-management options; beliefs related to cancer risk and risk management; and involvement with loved ones who had cancer. Eligible individuals were non-Hispanic white and non-Hispanic Black adult women who self-identified as having high risk of breast cancer and had no personal history of cancer. Between October 2018 and August 2019, 1053 respondents completed the online survey. Of these, 717 were confirmed through risk prediction modeling to have a lifetime breast cancer risk of ≥ 20%. Sociodemographic characteristics of this sample were compared to those of nationally representative samples of the US population: the 2019 Health Information National Trends Survey and the Pew Research Center report: Jewish Americans in 2020.

RESULTS

The sample of 717 women at objectively high risk of breast cancer was largely (95%) recruited from non-clinical sources. Of these respondents, only 31% had seen a genetic counselor, 34% had had genetic testing specific to breast cancer risk, and 35% had seen at least one breast or cancer care specialist. The sample includes 35% Black respondents and 8% with Ashkenazi Jewish ancestry. Although encompassing a substantial range of ages, incomes, and education levels, respondents are overall somewhat younger, higher-income, and more educated than the US population as a whole.

CONCLUSIONS

The DSM dataset offers comprehensive data from a community-based, diverse sample of women at high risk of breast cancer. The dataset includes substantial proportions of Black and Ashkenazi Jewish women and women who are not already in clinical care related to their breast cancer risk. This sample will facilitate future studies of risk-management behaviors among women who are and are not receiving high-risk care, and of variations in risk-management experiences across race and ethnicity.

Breast Cancer Risk and Breast-Cancer-Specific Mortality following Risk-Reducing Salpingo-Oophorectomy in BRCA Carriers: A Systematic Review and Meta-Analysis

BACKGROUND

Risk-reducing salpingo-oophorectomy (RRSO) is the gold standard method of ovarian cancer risk reduction, but the data are conflicting regarding the impact on breast cancer (BC) outcomes. This study aimed to quantify BC risk/mortality in BRCA1/BRCA2 carriers after RRSO.

METHODS

We conducted a systematic review (CRD42018077613) of BRCA1/BRCA2 carriers undergoing RRSO, with the outcomes including primary BC (PBC), contralateral BC (CBC) and BC-specific mortality (BCSM) using a fixed-effects meta-analysis, with subgroup analyses stratified by mutation and menopause status.

RESULTS

RRSO was not associated with a significant reduction in the PBC risk (RR = 0.84, 95%CI: 0.59-1.21) or CBC risk (RR = 0.95, 95%CI: 0.65-1.39) in BRCA1 and BRCA2 carriers combined but was associated with reduced BC-specific mortality in BC-affected BRCA1 and BRCA2 carriers combined (RR = 0.26, 95%CI: 0.18-0.39). Subgroup analyses showed that RRSO was not associated with a reduction in the PBC risk (RR = 0.89, 95%CI: 0.68-1.17) or CBC risk (RR = 0.85, 95%CI: 0.59-1.24) in BRCA1 carriers nor a reduction in the CBC risk in BRCA2 carriers (RR = 0.35, 95%CI: 0.07-1.74) but was associated with a reduction in the PBC risk in BRCA2 carriers (RR = 0.63, 95%CI: 0.41-0.97) and BCSM in BC-affected BRCA1 carriers (RR = 0.46, 95%CI: 0.30-0.70). The mean NNT = 20.6 RRSOs to prevent one PBC death in BRCA2 carriers, while 5.6 and 14.2 RRSOs may prevent one BC death in BC-affected BRCA1 and BRCA2 carriers combined and BRCA1 carriers, respectively.

CONCLUSIONS

RRSO was not associated with PBC or CBC risk reduction in BRCA1 and BRCA2 carriers combined but was associated with improved BC survival in BC-affected BRCA1 and BRCA2 carriers combined and BRCA1 carriers and a reduced PBC risk in BRCA2 carriers.

Attitudes towards risk-reducing early salpingectomy with delayed oophorectomy for ovarian cancer prevention: a cohort study

OBJECTIVE

To determine risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) acceptability and effect of surgical prevention on menopausal sequelae/satisfaction/regret in women at increased ovarian cancer (OC) risk.

DESIGN

Multicentre, cohort, questionnaire study (IRSCTN:12310993).

SETTING

United Kingdom (UK).

POPULATION

UK women without OC ≥18 years, at increased OC risk, with/without previous RRSO, ascertained through specialist familial cancer/genetic clinics and BRCA support groups.

METHODS

Participants completed a 39-item questionnaire. Baseline characteristics were described using descriptive statistics. Logistic/linear regression models analysed the impact of variables on RRESDO acceptability and health outcomes.

MAIN OUTCOMES

RRESDO acceptability, menopausal sequelae, satisfaction/regret.

RESULTS

In all, 346 of 683 participants underwent risk-reducing salpingo-oophorectomy (RRSO). Of premenopausal women who had not undergone RRSO, 69.1% (181/262) found it acceptable to participate in a research study offering RRESDO. Premenopausal women concerned about sexual dysfunction were more likely to find RRESDO acceptable (odds ratio [OR] = 2.9, 95% CI 1.2-7.7, P = 0.025). Women experiencing sexual dysfunction after premenopausal RRSO were more likely to find RRESDO acceptable in retrospect (OR = 5.3, 95% CI 1.2-27.5, P < 0.031). In all, 88.8% (143/161) premenopausal and 95.2% (80/84) postmenopausal women who underwent RRSO, respectively, were satisfied with their decision, whereas 9.4% (15/160) premenopausal and 1.2% (1/81) postmenopausal women who underwent RRSO regretted their decision. HRT uptake in premenopausal individuals without breast cancer (BC) was 74.1% (80/108). HRT use did not significantly affect satisfaction/regret levels but did reduce symptoms of vaginal dryness (OR = 0.4, 95% CI 0.2-0.9, P = 0.025).

CONCLUSION

Data show high RRESDO acceptability, particularly in women concerned about sexual dysfunction. Although RRSO satisfaction remains high, regret rates are much higher for premenopausal women than for postmenopausal women. HRT use following premenopausal RRSO does not increase satisfaction but does reduce vaginal dryness.

TWEETABLE ABSTRACT

RRESDO has high acceptability among premenopausal women at increased ovarian cancer risk, particularly those concerned about sexual dysfunction.

Involvement and Influence of Healthcare Providers, Family Members, and Other Mutation Carriers in the Cancer Risk Management Decision-Making Process of BRCA1 and BRCA2 Mutation Carriers

Deciding between increased cancer screening or prophylactic surgery and the timing of such procedures can be a difficult and complex process for women with BRCA mutations. There are gaps in our understanding of involvement of others in the decision-making process for women with BRCA mutations. This study evaluated the management decision-making process of women with BRCA mutations, focusing on the involvement of others. Grounded theory was used to analyze and code risk management decision-making information from interviews with 20 BRCA mutation carriers. Unaffected at-risk participants with a BRCA mutation, those under age 40, and those with no children described having a difficult time making risk management decisions. Physicians were an integral part of the decision-making process by providing decisional support and management recommendations. Family members and other mutation carriers filled similar yet distinct roles by providing experiential information as well as decisional and emotional support for carriers. Participants described genetic counselors as short-term providers of risk information and management recommendations. The study findings suggest that unaffected at-risk women, women under 40, and those who do not have children may benefit from additional support and information during the decision-making process. Genetic counselors are well trained to help women through this process and connect them with resources, and may be under-utilized in long-term follow-up for women with a BRCA mutation.

Psychological factors associated with the intention to choose for risk-reducing mastectomy in family cancer clinic attendees

OBJECTIVES

Women seeking counseling because of familial breast cancer occurrence face difficult decisions, such as whether and when to opt for risk-reducing mastectomy (RRM) in case of BRCA1/2 mutation. Only limited research has been done to identify the psychological factors associated with the decision for RRM. This study investigated which psychological factors are related to the intention to choose for RRM.

MATERIALS & METHODS

A cohort of 486 cancer-unaffected women with a family history of breast cancer completed the following questionnaires prior to genetic counseling: the Cancer Worry Scale, Positive And Negative Affect Scale, Perceived Personal Control Scale, Hospital Anxiety and Depression Scale and State Anxiety Scale and questions regarding socio-demographic characteristics, family history, risk perception and RRM intention. Multivariate logistic regression was used to analyze the relation between psychological factors and women's intention to choose for RRM.

RESULTS

Factors associated with RRM intention were high positive affect (OR = 1.86, 95%CI = 1.12-3.08), high negative affect (OR = 2.52, 95%CI = 1.44-4.43), high cancer worry (OR = 1.65, 95%CI = 1.00-2.72), high perceived personal control (OR = 3.58, 95%CI = 2.18-5.89), high risk-perception (OR = 1.85, 95%CI = 1.15-2.95) and having children (OR = 2.06, 95%CI = 1.21-3.50).

CONCLUSION

Negative and positive affects play an important role in the intention for RRM. Furthermore, perceived personal control over the situation is associated with an intention for RRM. In addition to focusing on accurate risk communication, counseling should pay attention to the influence of perceived control and emotions to facilitate decision-making.

The impact of risk-reducing gynaecological surgery in premenopausal women at high risk of endometrial and ovarian cancer due to Lynch syndrome

Women with Lynch syndrome (LS) have a significantly increased lifetime risk of endometrial cancer (40-60 %) and ovarian cancer (7-12 %). Currently there is little evidence to support the efficacy of screening for the early detection of these cancers. Another option is risk-reducing hysterectomy and/or bilateral salpingo-oophorectomy (BSO). Research on the impact of BSO in premenopausal women with a non-LS associated family history cancer has generally shown that women have a high level of satisfaction about their decision to undergo surgery. However, debilitating menopausal symptoms and sexual dysfunction are common post-surgical problems. We used a mixed methods study to explore the impact of risk-reducing gynaecological surgery in women with LS: 24 women were invited to take part; 15 (62.5 %) completed validated questionnaires and 12 (50 %) participated in semi-structured interviews. Our results suggest that risk reducing surgery does not lead to significant psychological distress and the women tend not to think or worry much about developing cancer. However, they tend to be distressed about the physical and somatic symptoms associated with menopause; their social well-being is somewhat affected, but sexual difficulties are minimal. The women reported being overwhelmingly satisfied with their decision to have surgery and with the quality of information they received prior to the operation. However, they felt underprepared for menopausal symptoms and received conflicting advice about whether or not to use HRT. Recommendations from the study include that professionals discuss the menopause, its side effects and HRT in detail prior to surgery.

Genetic counseling content: How does it impact health behavior?

Women with hereditary breast-ovarian cancer face decisions about screening (transvaginal ultrasound, CA125, mammography, breast exams) and proactive (before cancer) or reactive (after cancer) surgery (oophorectomy, mastectomy). The content of genetic counseling and its relation to these key health behaviors is largely unexamined. Ashkenazi Jewish women (n = 78) were surveyed through the process of genetic testing and had audiorecorded counseling sessions available for Linguistic Inquiry and Word Count analysis. Proportions for participant and counselor cognitive and affective content during sessions were used as primary predictor variables in linear mixed models for change in intentions for screening and treatment and in self-reported screening. Cognitive and affective content were important predictors of behavior. Counselor cognitive content was associated with ovarian screening. An interaction effect also emerged for CA-125, such that counselor cognitive content plus participant cognitive content or counselor affective content were associated with more screening. Teasing out the factors in risk communication that impact decision-making are critical, and affect from a risk communicator can spur action, such as cancer screening.

Adapting the coping in deliberation (CODE) framework: a multi-method approach in the context of familial ovarian cancer risk management

OBJECTIVE

To test whether the coping in deliberation (CODE) framework can be adapted to a specific preference-sensitive medical decision: risk-reducing bilateral salpingo-oophorectomy (RRSO) in women at increased risk of ovarian cancer.

METHODS

We performed a systematic literature search to identify issues important to women during deliberations about RRSO. Three focus groups with patients (most were pre-menopausal and untested for genetic mutations) and 11 interviews with health professionals were conducted to determine which issues mattered in the UK context. Data were used to adapt the generic CODE framework.

RESULTS

The literature search yielded 49 relevant studies, which highlighted various issues and coping options important during deliberations, including mutation status, risks of surgery, family obligations, physician recommendation, peer support and reliable information sources. Consultations with UK stakeholders confirmed most of these factors as pertinent influences on deliberations. Questions in the generic framework were adapted to reflect the issues and coping options identified.

CONCLUSIONS

The generic CODE framework was readily adapted to a specific preference-sensitive medical decision, showing that deliberations and coping are linked during deliberations about RRSO.

PRACTICE IMPLICATIONS

Adapted versions of the CODE framework may be used to develop tailored decision support methods and materials in order to improve patient-centred care.

Intentions for risk-reducing surgery among high-risk women referred for BRCA1/BRCA2 genetic counseling

OBJECTIVE

Genetic testing for breast and ovarian cancer susceptibility is now part of routine clinical practice. Although rates of risk-reducing surgery following genetic testing have been increasing, little is known about attitudes toward risk-reducing surgery in women prior to genetic counseling and testing. This study examines correlates of patient intentions to undergo risk-reducing mastectomy (RRM) and risk-reducing oophorectomy (RRO).

METHODS

Participants were 696 women, ages 21-85, who sought breast cancer gene 1 and 2 (BRCA1/2) genetic counseling and had at least a 10% risk of carrying a mutation. The sample included women who were affected with breast or ovarian cancer and unaffected women with a known familial BRCA1/2 mutation. Participants completed a precounseling telephone questionnaire.

RESULTS

Prior to receiving genetic counseling, 23.3% of participants were considering RRM and 42.5% were considering RRO. Variables that were independently associated with RRM intentions were cancer-specific distress (OR = 1.14, 95% CI = 1.03-1.26), perceived risk of breast cancer (OR = 1.16, 95% CI = 1.05-1.28), education (OR = 1.76, 95% CI = 1.03-2.99), and age (OR = 0.96, 95% CI = 0.95-0.98). Predictors of RRO intentions were perceived risk for ovarian cancer (OR = 1.25, 95% CI = 1.14-1.37), perceived risk of carrying a BRCA1/2 mutation (OR = 1.74, 95% CI = 1.15-2.62), marital status (OR = 1.92, 95% CI = 1.34-2.76), and age (OR = 1.02, 95% CI = 1.00-1.03).

CONCLUSIONS

Because precounseling intentions predict subsequent risk-reducing surgery decisions, this study identified patient factors associated with surgical intentions. These factors reinforce the critical role for pretest genetic counseling in communicating accurate risk estimates and management options, and addressing psychosocial concerns, to facilitate informed decision making regarding RRM and RRO.

Understanding the needs of women considering risk-reducing salpingo-oophorectomy

BACKGROUND

Because of the significantly increased lifetime risk of ovarian cancer associated with inheritance of a germline mutation in the BRCA1/2 genes, women with a deleterious mutation are recommended to undergo risk-reducing salpingo-oophorectomy at age 35 years or once child-bearing is complete. Significant time is often spent by nurses trained in genetics providing counseling to improve the decision-making process. The decision to undergo surgery is complex and laden with several sources of uncertainty.

OBJECTIVE

We conducted a qualitative study among female carriers of deleterious BRCA1/2 mutations to address these uncertainties.

METHODS

Twelve qualitative interviews were conducted with women who had received a positive BRCA1/2 test result to explore their understanding of ovarian cancer risk, prevention options, and resource needs. Qualitative content analysis was performed.

RESULTS

Significant information gaps in level of risk, other factors associated with ovarian cancer, and details of prophylactic oophorectomy were identified. Personal experience with cancer colored the degree of risk perception associated with the inherited mutation. Fear of the adverse effects of surgical menopause, both physiological and psychosocial, was common. Women expressed interest in hearing from other women facing the same decision.

CONCLUSIONS

Women facing the decision to undergo risk-reducing salpingo-oophorectomy have several information gaps and unmet needs despite comprehensive counseling.

IMPLICATIONS FOR PRACTICE

Based on our findings, we make specific recommendations that will guide nursing practice and future research.

The psychological impact of breast and ovarian cancer preventive options in BRCA1 and BRCA2 mutation carriers

This study was performed to describe the impact of preventive options on the psychological condition of BRCA1/BRCA2 carriers. A sample of 52 cancer-affected (C-A) and 27 cancer-unaffected (C-UN) women were enrolled after gene test disclosure (T0). Psychological evaluations were performed at T0 and 15 months later (T1). The surgical options were more likely to be chosen in C-A women (62%), although a consistent proportion of C-UN women (30%) also opt for these preventive measures. At the baseline, both samples had average anxiety and depression scores below the cut-off value, restrained average cancer worry scores and a risk perception consistent with the risk percentage provided during genetic counselling. The longitudinal results indicated no clinically meaningful variations in the anxiety and depression scores in either of the two samples. Statistically significant reductions in cancer-risk perception emerged in women who chose surgery in both C-A and C-UN women. In BRCA1/BRCA2 mutation carriers, surveillance does not influence their initial psychological condition, whereas prophylactic surgery has a significant impact in reducing the perceived risk and worry about getting sick. C-A and C-UN women have to be considered as two separate populations of BRCA mutation carriers requiring personalized approaches to risk management.

Catalysts to withdrawal from familial ovarian cancer screening for surgery and reactions to discontinued screening: a qualitative study

Women at high risk of familial ovarian cancer face a potentially difficult risk management choice between unproven ovarian cancer screening (OCS) and bilateral salpingo-oophorectomy (BSO). It is not fully understood why women who initially opt for OCS may later undergo BSO, nor what the impact of this may be. This study explored the catalysts for surgery and reactions to discontinuing OCS. Semi-structured interviews were completed with 21 women who had undergone surgery having initially chosen OCS to explore their screening experiences, reasons for and feelings about surgery, and reactions to discontinuing OCS. The invasive nature and frequency of OCS were not by themselves a catalyst for surgery. A number of catalysts, including abnormal OCS test results, and secondary considerations, such as age-related factors, were found to prompt surgery. The emotional impact of discontinuing OCS following BSO varied between relief, acceptance, and loss of reassurance. OCS appears to be an acceptable risk management strategy under certain circumstances, but varying factors can prompt the decision to opt instead for BSO. The complexity of this management change decision should not be underestimated and needs to be taken into account by clinicians assisting women making choices. These findings highlight the importance of the timing of decision-making about BSO and that risk management options need routine reconsideration, through clinical discussions, information and support.

Prophylactic Mastectomy: An Appraisal

The main indication of prophylactic mastectomy pertains to BRCA1 or BRCA2 mutation carriers. Prophylactic mastectomy includes the simple method and the subcutaneous method. Both methods can be followed by breast plastic reconstruction either at the same time or later. This review examines key issues regarding prophylactic mastectomy: the selection of patients, its effectiveness, its limitations, convergence/divergence in existing guidelines, and future perspectives.

Follow-up of carriers of BRCA1 and BRCA2 variants of unknown significance: variant reclassification and surgical decisions

PURPOSE

: Approximately 5-10% of patients who undergo genetic testing of BRCA1 and BRCA2 receive a variant of unknown significance (VUS) result. The ambiguous nature of a VUS may increase difficulty in patient understanding and decision making regarding risk reduction and surveillance options, including cancer risk-reducing surgeries. VUS reclassification to benign or deleterious may occur in time; however, clinical decisions may need to be made expeditiously, and some patients may pursue irreversible treatments before VUS reclassification.

METHODS

: We reviewed the surgical decisions of 107 women postdisclosure of a BRCA VUS result counseled at our institute between 1998 and 2009.

CONCLUSION

: Among women receiving a BRCA VUS result at our center, 11 of 107 (10.3%) pursued cancer risk-reducing mastectomy and 22 of 107 (20.6%) pursued cancer risk-reducing bilateral salpingo-oophorectomy. Reclassification of VUS occurred up to 9 years after testing, and 5 of 22 (22.7%) women followed up for 8 or more years continue to have a VUS result. We discuss considerations for providers of genetic services to discuss with patients who receive a VUS result.

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.

Choice of management of southern Chinese BRCA mutation carriers

BACKGROUND

Mutations in the BRCA genes confer greater risk of developing breast, ovarian, and prostate cancer. Families carrying the mutation can have intensive surveillance and take preventative measures. This is the first report on the uptake of such interventions in Chinese mutation carriers residing in Asia.

METHODS

Breast and ovarian cancer index patients and family members referred for genetic counselling and testing who are found to carry the BRCA mutations were included in this multicenter study.

RESULTS

A total of 31 patients with breast and/or ovarian cancer were found to carry BRCA1 or BRCA2 mutations. Forty-one tested family members also carried the mutations. Of the females, 85.7% of the index patients opted for breast surveillance and 23.8% for prophylactic mastectomy. Of the family members, 82.4% chose breast surveillance and 17.7% had prophylactic mastectomy. The majority of index patients and family members preferred ovarian surveillance (84 and 82.4%). Amongst the index patients, 32% decided for prophylactic salpingo-oophorectomy; 17.6% of the family members who did not have history of ovarian cancer decided to have prophylactic salpingo-oophorectomy. All male index patients agreed to breast and prostate surveillance, including breast clinical examination and PSA monitoring. For those male family members found to be BRCA mutation carriers, 56.3% agreed to have breast surveillance and 66.7% agreed to have prostate surveillance. No index patient or family member agreed to any form of chemoprevention.

CONCLUSIONS

Chinese BRCA mutation carriers have a higher uptake of cancer surveillance than prophylactic surgery and have a lack of interest in the use of chemoprevention drugs.

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.

The process of deciding about prophylactic surgery for breast and ovarian cancer: Patient questions, uncertainties, and communication

Many, women who have, or are at risk for, BRCA, 1/2 mutations or breast cancer decline prophylactic surgery, but questions remain as to how they make and experience these decisions. Our methods consisted of interviewing 32 women for 2 hr each; 19 were tested, 20 were symptomatic. Our results showed that these surgical options forced women to confront questions, involving stresses and uncertainties, regarding: implications of test results, prognoses with and without surgery, and effects of surgery (e.g., on self-image). Given these dilemmas, many women turned to doctors who then ranged in what and how they communicated about these issues, and how strongly they offered input. Some patients felt disappointed at provider non-directiveness, while others found providers too directive. Patients turned to family members and friends, who also ranged in how and what they communicated, and whether they agreed with the patient and/or each other. Many women turned to patient communities, but then had to decide how involved to be, and what information to provide or accept. These data suggest that providers and others may need to be more aware of the series of questions, involving stresses and uncertainties, that these women face, and the complex roles providers themselves may play. These data highlight needs for physicians to be able to address these issues flexibly, gauging patient preferences for information and paternalism (vs. autonomy). These data suggest areas for future research: for example, on how providers decide whether, what and how to communicate about these issues, and how these choices shape treatment decisions.

Association of shared decision-making with type of breast cancer surgery: a cross-sectional study

Background

Although some studies examined the association between shared decision-making (SDM) and type of breast cancer surgery received, it is little known how treatment decisions might be shaped by the information provided by physicians. The purpose of this study was to identify the associations between shared decision making (SDM) and surgical treatment received.

Methods

Questionnaires on SDM were administered to 1,893 women undergoing primary curative surgery for newly diagnosed stage 0-II localized breast cancer at five hospitals in Korea. Questions included being informed on treatment options and the patient's own opinion in decision-making.

Results

Patients more likely to undergo mastectomy were those whose opinions were respected in treatment decisions (adjusted odds ratio, aOR), 1.40; 95% confidence interval (CI), 1.14-1.72) and who were informed on chemotherapy (aOR, 2.57; CI, 2.20-3.01) or hormone therapy (aOR, 2.03; CI, 1.77-2.32). In contrast, patients less likely to undergo mastectomy were those who were more informed on breast surgery options (aOR, 0.34; CI, 0.27-0.42). In patients diagnosed with stage 0-IIa cancer, clinical factors and the provision of information on treatment by the doctor were associated with treatment decisions. In patients diagnosed with stage IIb cancer, the patient's opinion was more respected in treatment decisions.

Conclusion

Our population-based study suggested that women's treatment decisions might be shaped by the information provided by physicians, and that women might request different information from their physicians based on their preferred treatment options. These results might need to be confirmed in other studies of treatment decisions.

Ovulation in the absence of the ovarian surface epithelium in the primate

The ovarian surface epithelium (OSE) has a prominent role in ovarian cancer in women, but no studies have been conducted to evaluate its role in normal ovarian function. Data from other species suggest the OSE is needed for ovulation. We have tested whether the OSE is needed for follicle rupture, a necessary step in ovulation, using the nonhuman primate, rhesus macaque. The OSE was removed in two different short-term protocols spanning a single periovulatory interval--one protocol used a cytology brush to remove the OSE only from the follicle apex, and one used mild detergent to remove the entire OSE--and in one long-term protocol spanning 6 wk (two periovulatory intervals) that removed the entire OSE with detergent. Serum levels of estrogen and progesterone (E and P) were monitored, and sectioned ovaries were examined for evidence of successful OSE removal and follicle rupture. In the short-term protocols, removal of the OSE over the follicle apex did not prevent follicle rupture (n = 4 ovaries), but removal of the entire OSE using detergent did in four of six cases. In the long-term protocol, when ovaries were collected after the second periovulatory interval, all the ovaries (n = 5) showed evidence of follicle rupture. In all the protocols, E and P production appeared unaffected. Detergent penetrated up to 40 microm into the ovary. This may have transiently disrupted the stroma and caused follicle rupture failure. We conclude that the primate OSE is not essential for ovulation and perhaps can be removed without lasting consequence.

Perceptions of high-risk care and barriers to care among women at risk for hereditary breast and ovarian cancer following genetic counseling in the community setting

Data are limited regarding barriers to care among women, with or at risk for hereditary breast and ovarian cancer (HBOC), following genetic counseling in the community setting. Using a telephone survey, we retrospectively addressed perceptions of post-genetic counseling medical care and barriers to care among 69 at-risk women from the non-academic setting. Of these, all agreed that following cancer screening recommendations was better than not following them; none felt recommendations were too difficult to follow; all believed screening would help keep them healthy; 57% believed screening would prevent cancer. Twenty-five percent noted discomfort with breast imaging; 29% found ovarian cancer screening uncomfortable. Close to a quarter of participants reported difficulty deciding whether or not to undergo risk-reducing mastectomy while 10% noted difficulty deciding for or against bilateral salpingo-oophorectomy. There were no perceived major barriers to care, although 38% felt that screening reminders would be helpful, and 10% needed more help in following through with care. Overall, participants believed that they were benefiting from their post-genetic counseling medical care. This work identified HBOC-related support needs to include: informational resources that promote improved understanding of cancer risk and high-risk management; screening reminder systems; and decision support tools.

Women's decision making about risk-reducing strategies in the context of hereditary breast and ovarian cancer: a systematic review

Women who have a mutation in the BRCA1 or BRCA2 genes have up to an 87% lifetime risk of breast cancer and up to a 40% lifetime risk of ovarian cancer. Cancer prevention and early detection strategies are often considered by these women to address this heightened risk. Risk-reducing strategies include risk-reducing mastectomy and oophorectomy, breast and ovarian cancer screening, and chemoprevention. This systematic literature review summarizes the factors and contexts that influence decision making related to cancer risk-reducing strategies among women at high-risk for hereditary breast and ovarian cancer. In the 43 published research articles reviewed, three main types of factors are identified that influence high-risk women's decisions about risk-reducing strategies: a) medical and physical factors, b) psychological factors and c) social context factors. How these factors operate in women's lives over time remains unknown, and would best be elucidated through prospective, longitudinal research, as well as qualitative research.

Perception of screening and risk reduction surgeries in patients tested for a BRCA deleterious mutation

BACKGROUND

Women at a high risk for breast cancer are offered choices for screening or prophylactic surgeries. The aim of this study was to evaluate opinions regarding screening and surgical strategies in high-risk women.

METHODS

Women at the authors' institution who received BRCA1 of 2 testing before July 2005 were sent a follow-up patient survey. The authors compared responses of women who tested positive for a deleterious mutation with those who tested negative. For those who expressed an opinion (agree vs disagree), a 2-sided Fisher exact test was used to compare responses.

RESULTS

A total of 540 surveys were sent, and 312 were returned (58%). Of these, 217 had breast cancer, and 86 women tested positive for a mutation. No BRCA+ women felt mammograms were difficult to get because of discomfort, whereas 5.4% of the BRCA- group did (P = .039). Seventy percent of BRCA+ women agreed that prophylactic mastectomy (PM) is the most effective means for reducing risk, compared with 40% of BRCA- women (P < .001). PM was felt to be the only way to reduce worry in 64.7% of BRCA+ and in 34.4% of BRCA- women (P < .001). PM was felt to be too drastic for 36.1% of BRCA+ and 40.5% of BRCA- women (P = .562). Difficulty in deciding between screening and PM occurred in 23.9% of BRCA+ and 12.5% of BRCA- women (P = .046). After excluding women with bilateral breast cancers, 81.0% of women who agreed that PM was best to reduce risk underwent a PM versus 19.1% of those who disagreed (P < .001). Of women who felt PM was the only way to reduce worry, 84.2% underwent PM. Only 15.8% of women who did not believe that it was the only way to decrease worry underwent PM (P < .001).

CONCLUSIONS

BRCA mutation carriers were more likely to believe PM to be the best way to reduce both risk and worry of breast cancer. High-risk women who agreed that PM was more likely to reduce risk and worry of breast cancer were more likely to proceed with this intervention.

Standard psychological consultations and follow up for women at increased risk of hereditary breast cancer considering prophylactic mastectomy

Background

Women at increased (genetic) risk of breast cancer have to weigh the personal pros and cons of prophylactic mastectomy (PM) as an option to reduce their cancer risk. So far, no routine referral to a psychologist has been investigated for women considering PM. Aim of this study was to asses: 1) the acceptance of the offer of a standard psychological consultation as part of pre-surgical decision-making in high-risk women, 2) reasons for PM and reasons for postponing it, 3) the need for additional psychological interventions, and factors associated, and 4) the frequency of psychiatric/psychological treatment history.

Methods

During a 30 months period, women at high risk considering PM were offered a psychological consultation. The content of these, and follow-up, consultations were analyzed.

Results

Most women (70 out of 73) accepted the psychological consultation, and 81% proceeded with PM. Main reasons for undergoing PM were to reduce anxiety about cancer, and to reduce the cancer risk. Uncertainty about surgery and the need for further information were the reasons given most frequently for postponing PM. Additional psychological support was given to 31% before and 14% after PM. The uptake of additional support was significantly higher in women with a BRCA1/2 mutation. A history of psychiatric/psychological treatment was present in 36%, mainly consisting of depression and grief after death of a mother.

Conclusion

The uptake-rate of the standard psychological consultation indicates a high level of acceptability of this service for women deciding about PM. Since anxiety is one of the main reasons for considering PM, and depression and grief were present in a third, a standard consultation with a psychologist for high-risk women considering PM may be indicated. This may help them arrive at an informed decision, to detect and manage psychological distress, and to plan psychological support services.

Uptake and timing of bilateral prophylactic salpingo-oophorectomy among BRCA1 and BRCA2 mutation carriers

PURPOSE

To evaluate prophylactic salpingo-oophorectomy uptake and timing among BRCA1/2 mutation carriers in a cancer risk assessment program.

METHODS

Clinical records of female BRCA1/2 mutation carriers who received cancer genetic counseling between 1996 and 2003 were reviewed to determine the completion and the timing of prophylactic salpingo-oophorectomy. Logistic regression models evaluated associations between subject characteristics and surgery. Survival analysis methods were used to estimate the distribution of time to surgery.

RESULTS

Among 88 women, 70% underwent prophylactic salpingo-oophorectomy. Prophylactic salpingo-oophorectomy was associated with older age, white race, having children, and a family history of ovarian cancer. Many women waited more than 12 months to undergo surgery and some delayed by several years. Younger age and not having children were associated with delays to surgery.

CONCLUSION

Prophylactic salpingo-ooporectomy is an acceptable risk reduction measure for many BRCA1/2 mutation carriers. Some women make this decision many years after genetic testing. Continued discussion of the risks and benefits of risk reduction options may facilitate the uptake of recommended risk reduction interventions among BRCA mutation carriers.

Decision making regarding prophylactic mastectomy: stability of preferences and the impact of anticipated feelings of regret

PURPOSE

Women who test positive for a BRCA1/2 mutation face difficult choices to manage their breast cancer risk; one of these choices is whether to opt for prophylactic mastectomy. Few data are available about this decision-making process. The current study provides data regarding the stability of risk-management preferences over time and the factors that are associated with these preferences.

PATIENTS AND METHODS

We analyzed data from 338 women who opted for breast cancer antigen (BRCA) testing. First, we prospectively assessed preferences of 80 BRCA mutation carriers at five different points in time ranging from 1 week after blood sampling up to 9 months after BRCA-test disclosure. Second, we applied univariate and multivariate regression analyses to examine which medical, sociodemographic, and psychological factors are related to a preference for prophylactic mastectomy.

RESULTS

Ninety percent of the women already indicated a preference regarding risk management at baseline. Moreover, most women had stable preferences over time. Furthermore, anticipated feelings of regret in case of a hypothetical breast cancer diagnosis in the near future were strongly related to risk-management preference (odds ratio = 8.93; P < .0001).

CONCLUSION

Women seem to decide at a relatively early stage about their risk-management preferences. Many of them may be sensitive to the possibility of regret in case of a bad outcome. We discuss whether possible regret in the future is a rational reason for opting for prophylactic mastectomy, or whether it signifies an emotional coping process or strategy in which the future costs are no longer fully considered.

Women with BRCA1 or BRCA2 mutations renegotiating a post-prophylactic mastectomy identity: self-image and self-disclosure

The Facing Our Risk of Cancer Empowered (FORCE) website is devoted to women at risk for hereditary breast and ovarian cancers. One of the most frequently discussed topics on the archived messaged board has been prophylactic mastectomy (PM) for women with a BRCA1/2 mutation. We reviewed the messages, over a 4 year period, of 21 high risk women and their "conversational" partners who originally posted on a thread about genetic testing, genetic counseling and family history. We used a qualitative research inductive process involving close reading, coding and identification of recurrent patterns, relationships and processes in the data. The women sought emotional support, specific experiential knowledge and information from each other. They frequently found revealing their post PM status problematic because of possible negative reactions and adopted self-protective strategies of evasion and concealment outside of their web-based community. The FORCE message board was considered to be a safe place in which the women could be truthful about their choices and feelings. Results are discussed in terms of Goffman's concepts "stigma" and "disclosure" and Charmaz's concepts "interruptions," "intrusions" and a "dreaded future."

Risk reduction and health promotion behaviors following genetic testing for adult-onset disorders

Although clinical genetic testing is available for over 1,000 inherited disorders, consequences of predictive genetic testing have been most extensively examined for hereditary breast and ovarian cancer (HBOC), hereditary colon cancer, and Huntington disease (HD). These focus primarily on psychological, ethical, legal, and social aspects of genetic testing. Genetic testing may also provide information that can lead to behaviors that promote health and reduce risk for disease, reflecting options available for the disorder for which the person is at risk. However, regardless of condition, people completing a genetic test may inform relatives about the results of the test and implications for their risk to develop the condition. Literature on risk reduction behaviors and communication focuses on families with HBOC or colorectal cancer. Few reports document behaviors for other conditions. This paper presents a systematic review of the research literature on risk reduction and health promotion behaviors following clinical genetic testing for adult onset conditions, primarily HBOC, familial colon cancers, and HD. Insights gleaned from this review are discussed as a basis for planning monitoring of health promotion and risk-reduction behaviors for genetic testing for present and future use.
