Background: Contralateral prophylactic mastectomy (CPM) remains a personal decision, influenced by psychosocial factors, including cosmesis and peace of mind. Although use of CPM is disproportionately low among Black patients, the degree to which these disparities are driven by patient- vs hospital-level factors remains unknown., Study Design: Patients undergoing mastectomy for nonmetastatic ductal or lobular breast cancer were tabulated using the National Cancer Database from 2004 to 2020. The primary endpoint was receipt of CPM. Multivariable logistic regression models were constructed with interaction terms between Black-serving hospital (BSH) status and patient race to evaluate associations with CPM. Cox proportional hazard models were used to evaluate long-term survival., Results: Of 597,845 women studied, 70,911 (11.9%) were Black. After multivariable adjustment, Black race (adjusted odds ratio 0.65, 95% CI 0.64 to 0.67) and treatment at BSH (adjusted odds ratio 0.84, 95% CI 0.83 to 0.85) were independently linked to lower odds of CPM. Although predicted probability of CPM was universally lower at higher BSH, Black patients faced a steeper reduction compared with White patients. Receipt of CPM was linked to improved survival (hazard ratio [HR] 0.84, 95% CI 0.83 to 0.86), whereas Black race was associated with a greater HR of 10-year mortality (HR 1.14, 95% CI 1.12 to 1.17)., Conclusions: Hospitals serving a greater proportion of Black patients are less likely to use CPM, suggestive of disparities in access to CPM at the institutional level. Further research and education are needed to characterize surgeon-specific and institutional practices in patient counseling and shared decision-making that shape disparities in access to CPM., (Copyright © 2024 by the American College of Surgeons.

Introduction: Despite national guidelines against contralateral prophylactic mastectomy (CPM) in low- to moderate-risk breast cancer, CPM use continues to rise. Breast reconstruction improves health-related quality of life and satisfaction among women undergoing mastectomy. Given the lack of data regarding factors associated with reconstruction after CPM and the known benefits of reconstruction, we sought to investigate whether disparities exist in receipt of reconstruction after CPM., Methods: The 2004-2017 National Cancer Database was queried to identify women diagnosed with breast cancer who underwent unilateral mastectomy with CPM. Patients were divided into two groups: those who underwent planned reconstruction at any timepoint and those who did not. A secondary analysis comparing types of reconstruction (tissue, implant, combined) was conducted. Patient, tumor, and demographic characteristics were analyzed using chi-square test and odds ratios were calculated using generalized estimating equations., Results: The cohort included 1,73,249 women: 95,818 (55.3%) underwent reconstruction and 77,431 (45.7%) did not. Both the rate CPM and the proportion of women undergoing reconstruction after CPM increased between 2004 and 2017. Of the women who had reconstruction, 40,840 (51.7%) received implants, 29,807 (37.7%) had tissue, and 8352 (10.6%) had combined reconstruction. After adjusted analysis, factors associated with reconstruction were young age, Hispanic ethnicity, private insurance, and living in an area with the highest education and median income (P < 0.01). Patients who underwent reconstruction were less likely to have radiation (P < 0.01) and chemotherapy (P < 0.01), more likely to have stage I disease (P < 0.01), and to be treated at an integrated cancer center (P < 0.01)., Conclusions: Reconstruction after CPM is disproportionately received by younger women, Hispanics, those with private insurance, and higher socioeconomic status and education. While the rate of reconstruction after CPM is increasing, there remain significant disparities. Conscious efforts must be made to eliminate these disparities, especially given the known benefits of reconstruction after mastectomy., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Currently, research on the prognostic factors of unilateral breast cancer (UBC) patients receiving contralateral prophylactic mastectomy (CPM) is limited. This study aimed to construct a new nomogram to predict these patients' overall survival (OS)., Methods: In this retrospective study, 88,477 patients who underwent CPM or unilateral mastectomy (UM) were selected from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier curves and Cox regression analyses were used to determine the difference in the impact of the 2 surgical methods on the prognosis. Multivariate Cox analysis was used to determine the best prognostic variable and construct a nomogram. The concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve, decision curve analysis (DCA), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to evaluate the discrimination capability and clinical effectiveness of the nomogram., Results: The prognosis of patients receiving CPM and UM was significantly different. The DCA curves indicated that the nomogram could provide more excellent clinical net benefits for these patients. The NRI and IDI of the nomogram demonstrated that its performance was better than that of the classical tumor-node-metastasis (TNM) staging system., Conclusion: This study developed and validated a practical nomogram to predict the OS of UBC patients undergoing CPM, which provided a beneficial tool for clinical decision-making management., Competing Interests: Disclosure The authors declare no competing interests., (Copyright © 2024.

Introduction: This study aims to characterize longitudinal care management and evaluate the relationship between various patient factors and the likelihood of choosing risk-reducing behaviors in women with increased risk of developing breast cancer., Methods: A retrospective study was conducted to evaluate all adult female patients who had at least one clinic visit with a surgical provider for discussion of breast cancer risk assessment between January, 2017 to July, 2020 at an academic center. Patients with prior history of breast cancer were excluded. Patient details and strategies pursued at clinic visits were recorded. A time-to-event analysis was performed, and hazard ratios were determined to characterize associations between patient characteristics and time to pursuing risk-reducing care management., Results: There were 283 participants with at least one follow-up visit and 48 (17.0%) ultimately changed their initial strategy to either chemoprevention or prophylactic mastectomy. Patients with gene mutations were 6 times more likely to engage in risk-reducing management compared to those without (hazard ratio (HR) 5.99, P < 0.001). Those with histories of high-risk proliferative changes (HR 7.62, P < 0.001) and hysterectomy (HR 2.99, P = 0.019) were also more likely to engage in risk-reducing management. Age, race, and increased predicted risk of developing breast cancer (estimated by various calculators) were not associated with increased likelihood of engaging in risk-reducing strategies., Conclusion: Known gene mutations, history of high-risk proliferative changes, and prior hysterectomy were factors associated with women who were more likely to engage in risk-reducing strategies. These findings, when paired with patient reported outcome measures, may help guide shared decision-making., (Copyright © 2021. Published by Elsevier Inc.)

Objectives: Risk-reducing mastectomy (RRM) is one of key prevention strategies in female carriers of germline BRCA pathogenic/likely pathogenic variants (PV/LPV). We retrospectively investigated the rate, timing and longitudinal trends of bilateral RRM uptake and the incidence and types of cancers among unaffected BRCA carriers who underwent genetic counseling at the Institute of Oncology Ljubljana in Slovenia., Materials and Methods: Female BRCA carriers without personal history of cancer were included in the study. Clinical data on PV/LPV type, date of RRM, type of reconstructive procedure, occult carcinoma and histopathology results was collected and analyzed., Results: Of the 346 unaffected BRCA carriers (median age 43 years, 70% BRCA1, 30% BRCA2, median follow-up 46 months) who underwent genetic testing between October 1999 and December 2019, 25.1% had a RRM (range 35-50 years, median age at surgery 38 years). A significant difference in time to prophylactic surgery between women undergoing RRM only vs. women undergoing RRM combined with risk-reducing salpingo-oophorectomy was observed (22.6 vs 8.7 months, p = 0.0009). We observed an upward trend in the annual uptake in line with the previously observed Angelina Jolie effect. In 5.7% of cases, occult breast cancer was detected. No women developed breast cancer after RRM. Women who did not opt for surgical prevention developed BRCA1/2-related cancers (9.3%)., Conclusion: The uptake of RRM among unaffected BRCA carriers is 25.1% and is similar to our neighboring countries. No women developed breast cancer after RRM while women who did not opt for surgical prevention developed BRCA1/2 related cancers in 9.3% of cases. The reported data may provide meaningful aid for carriers when deciding on an optimal prevention strategy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 The Authors.

Background: Contralateral prophylactic mastectomy (CPM) is not recommended for average-risk women with breast cancer due to lack of evidence for survival benefit, yet recent studies demonstrate increasing CPM rates., Methods: We identified patients with breast cancer treated with unilateral mastectomy (UM) with or without CPM. Rates of malignancy in CPM specimens and factors in CPM rates were assessed., Results: From 2013 to 2017, 1353 patients had UM and 355 had CPM. Our institution's occult malignancy detection rate was 5.04%. CPM rates decreased from 31.6% to 17.3% (p < 0.001) over 5 years. Compared to patients receiving UM only, patients receiving CPMs had significantly higher reconstruction rates (p < 0.001), which did not significantly change over time (p = 0.551) and tended to be younger (p < 0.001)., Conclusions: Patients having UM have low risk of contralateral malignancy. CPM is associated with younger age and breast reconstruction, suggesting factors to identify for patient and provider education., Competing Interests: Declaration of competing interest The authors of this manuscript declare no conflicts of interest for this publication., (Copyright © 2021 Elsevier Inc.

Purpose: Identification of inherited breast cancer may guide cancer risk management. We sought to compare risk management practices across women with inherited breast cancer genes., Methods: Females with a pathogenic/likely pathogenic (P/LP) variant in BRCA1/2, PALB2, CHEK2, and/or ATM were surveyed about cancer risk management. Comparisons were made across genes., Results: The 235 participants with P/LP variants (186 BRCA1/2, 28 PALB2, 15 CHEK2, and 6 ATM) had a median age of 54 and 61% had a prior breast cancer diagnosis. For women with P/LP variants in BRCA1/2, PALB2, and ATM/CHEK2, bilateral mastectomy (BM) rates were 79%, 61%, and 52%, and bilateral oophorectomy (BO) rates were 89%, 30%, and 37%, respectively. Among women with P/LP variants in PALB2 and ATM/CHEK2, 27% of those who had a BO had a family history of ovarian cancer. Contralateral mastectomy rates for women with P/LP variants in PALB2 and ATM/CHEK2 with unilateral breast cancer were 60% and 58%, and BM rates for those without breast cancer were 57% and 29%, respectively., Conclusion: These findings suggest high rates of both contralateral mastectomies among those with unilateral breast cancer and BM among those without a breast cancer diagnosis across women with P/LP variants in high and moderate penetrance breast cancer genes. BO was also often utilized for risk reduction across these women. These findings suggest potential overtreatment through risk-reducing surgery, and highlight the importance of promoting guideline-adherent, risk-appropriate care.

Background: Breast reconstruction is a favorable option for women with BRCA1 or BRCA2 mutations (BRCA1/2 Mut+ ) who undergo risk-reducing mastectomy (RRM). We assessed characteristics of patients who underwent RRM, with or without breast reconstruction., Methods: We included 46 patients with BRCA1/2 Mut+ who underwent RRM from July 2011 to December 2017., Results: Among the 46 patients who underwent RRM, 3 had not been diagnosed with breast cancer (BC) and 43 had cancer in a single breast; 33 patients (71.7%) underwent breast reconstruction with RRM; and 13 patients (28.3%) did not undergo breast reconstruction. All of 3 patients who had not been diagnosed with BC underwent bilateral RRM with breast reconstruction. There was no significant difference of clinical characteristic between patients undergoing RRM with and without breast reconstruction. However, patients who decided to undergo RRM with the current diagnosis of BC had significantly higher rates of RRM with breast reconstruction than that of patients with a past history of BC (P = 0.043). The rate of nipple-sparing mastectomy (NSM) in patients with breast reconstruction was significantly higher (28 of the 37 breasts, 75.7%) than that in patients without reconstruction (3 of the 14 breasts, 21.4%) (P < 0.001). Two patients who had complications underwent RRM with breast reconstruction, and one of them had a history of irradiation after lumpectomy., Conclusions: For BRCA1/2 Mut+ patients, the decision of taking RRM with the diagnosis of current BC might affect whether they undergo immediate breast reconstruction with RRM. These patients who undergo RRM with breast reconstruction preferred NSM to skin-sparing mastectomies.

Patients undergoing the addition of a contralateral prophylactic mastectomy with unilateral breast cancer have an increased and potentially doubled post-operative complication rate. One documented detriment from post-operative complications is the potential delay in initiating adjuvant therapy. To determine if the addition of a gynecologic and/or plastic reconstructive procedure to breast surgery results in an increased risk of postoperative complications and re-admissions, we evaluated outcomes in patients undergoing single vs multi-site surgery in a large national surgical database. We utilized the National Surgery Quality Improvement Program (NSQIP) database to identify patients who underwent breast surgery between 2011 and 2015. We extracted patients who underwent prophylactic oophorectomy with or without hysterectomy as a comparison group. Chi square analysis was used to assess postoperative outcomes including complications, readmission, and reoperation. All statistics were performed in SPSS v. 24. During the study timeframe, 77 030 patients had a solitary or combined breast surgical procedure and a second cohort of 124 patients underwent gynecologic surgery. Breast cancer patients who did not have a simultaneous reconstruction or gynecologic procedure were older with more comorbidities. Patients undergoing coordinated procedures had a significantly longer length of stay, higher complication, readmission, and reoperation rates (P < 0.001 for all) as compared with patients who underwent single site surgery. Patients with surgery for breast cancer, either with a plastic or gynecologic procedure, have greater postoperative complications. Higher complication rates for those with coordinated operations may lead to delays in adjuvant therapy and discussions regarding the indications for simultaneous surgery are recommended., (© 2019 Wiley Periodicals, Inc.)

Background: Rising use of multigene panel testing has led to increased identification of variants of uncertain significance (VUS). Consensus guidelines state that clinicians should not make medical management decisions based on VUS findings. We sought to analyze how VUS affect management of patients at risk for hereditary breast cancer., Methods: All genetic testing reports for indications of hereditary breast cancer risk from a single tertiary-care institution from 2015 to 2018 were reviewed. Variants were grouped by pathogenicity (benign/likely benign, VUS, or pathogenic/likely pathogenic [P/LP]) and by breast cancer susceptibility (high, moderate, or none). Patient and management characteristics were compared by variant pathogenicity and breast cancer risk., Results: Overall, 563 patients underwent genetic testing for breast cancer risk; 336 VUS were identified in 228 (40.5%) of patients of which 26.4% were in high or moderate penetrance genes. P/LP results were found in 61 (10.8%) patients, of which 61.2% were identified in breast-specific moderate and high penetrance genes, and 38.7% were found in non-breast specific genes. Of variants found in high-risk genes, 54.5% were P/LP and 45.5% were VUS. On multivariable analysis, prophylactic mastectomy was associated with younger age and personal history of cancer, but not variant pathogenicity or penetrance. There were no differences in the use of post-test imaging, oophorectomy, or colonoscopy based on variant findings or age., Conclusions: In this era of multigene panel testing, genetic factors help to inform, but not dictate, complex decision-making in surveillance and management of patients at risk for hereditary breast cancer.

Background: We sought to determine how patient-physician communication affects patients' decision-making when choosing between contralateral prophylactic mastectomy (CPM) and unilateral mastectomy (UM)., Methods: atients with breast cancer who underwent mastectomy at our institution were approached with a survey regarding patient-physician communication in CPM., Results: Of 101 patients who completed the survey, 55 underwent CPM (54.5%). Thirty-three patients (33%) stated that their physician recommended UM, six (6%) stated their physician recommended CPM, and 61 (61%) stated they engaged in active participation in decision-making. Most patients whose doctors recommended UM chose UM (78.8%); similarly, 83.3% of those whose doctors recommended CPM chose CPM. Of 39 patients whose doctors recommended a particular surgical option, eight (20.5%) did not follow their doctor's advice. These patients were equally as satisfied with their decisions as those who followed their doctor's advice (P = 0.441). Patients engaging in active participation in decision-making tended to choose CPM (68.3% versus 30.8%, P < 0.001). Patients who did not engage in active participation were similarly satisfied with their decision as those who did (P = 0.286). Twelve patients (12%) stated they preferred their doctor to provide a recommendation, seven (7%) preferred to make the decision on their own, and 81 (81%) preferred to actively participate in their decision-making with the physician., Conclusions: Patients tend to follow physicians' recommendation of UM or CPM; patients engaging in SDM tend to choose CPM. Most patients prefer to engage in active participation in decision-making with their physician but were equally satisfied with their surgical decision whether they engaged in active participation or not., (Copyright © 2019 Elsevier Inc.

Background: American Society of Breast Surgeons (ASBrS) guidelines state that it is the responsibility of the surgeon to discuss the risks/benefits of and give a recommendation regarding contralateral prophylactic mastectomy (CPM). We conducted a survey of ASBrS members to evaluate the factors that affect this recommendation, confidence in this recommendation, and awareness/adoption of the guidelines., Methods: A survey was sent to the ASBrS membership. Vignettes with the following variables about breast cancer patient were randomly included: age, disease stage, receptor status, family history (FH) of breast cancer, and patient preference for CPM. Respondents were asked to estimate the patient's chance of developing contralateral cancer, whether they would recommend CPM, and their confidence in this recommendation, and about their familiarity with and use of the guidelines., Results: 536 members (21.9%) responded. The odds of recommending CPM and confidence in recommendation were higher in a younger patient, higher-stage disease, triple-negative and human epidermal growth factor receptor (HER)2+ relative to estrogen receptor (ER)+, and in women with FH. Of surgeons, 51% were familiar or very familiar with the guidelines and 38% used the guidelines most or all of the time. Surgeons who used the guidelines were not less likely to recommend CPM., Conclusions: While surgeons generally agree on the factors that are important in making a recommendation on CPM, there is variability in how strongly the different factors influence the recommendation and their confidence in that recommendation. In addition, while most surgeons were at least a little familiar with the ASBrS guidelines, the vast majority do not routinely use them.

Purpose: Previous studies have reported increased rates of contralateral prophylactic mastectomy (CPM) in the United States among women with unilateral breast cancer. These trends have primarily focused on younger breast cancer patients. Given the growing aging population in the United States, we sought to determine whether CPM use is also increasing in elderly patients., Methods: This population-based study identified patients in the surveillance epidemiology and end results (SEER) data. We determined the rate of CPM as a proportion of all surgically treated patients and as a proportion of all mastectomies. We compared the unadjusted CPM rates over the study period using the Cochrane-Armitage test for trend. We used a logistic regression model to test for the factors associated with CPM utilization., Results: We identified 261,281 patients ≥ 65 years who underwent surgical treatment for breast cancer. For all patients treated with surgery for invasive breast cancer, the use of CPM increased from 1 in 2004 to 3% in 2014 (200% increase). Among mastectomy patients, the use of CPM increased from 3 in 2004 to 7% in 2014 (133% increase). Young age, non-Hispanic white race, lobular histology, higher grade, increased stage, negative lymph node status, and recent year of diagnosis were significantly associated with increased CPM rates., Conclusions: For elderly patients the use of CPM has continued to increase in the United States. These observations warrant concern in light of increasing evidence that CPM does not improve oncological outcomes and is associated with increased morbidity in older patients.

Background: The aim of this study was to evaluate the trends of surgical treatments among young patients in T 1 N 0-1 M 0 stage based on the Surveillance, Epidemiology, and End Results database., Materials and Methods: Patients aged less than 40 y diagnosed between 1998 and 2015 were enrolled, with tumors in T 1 N 0-1 M 0 stage and not located in the central area. Differences in clinical-pathological characteristics were evaluated using chi-square tests. Multivariate logistic regression was used to measure the various factors associated with contralateral prophylactic mastectomy (CPM). Independent prognostic factors were evaluated by Cox model., Results: The total rate of breast-conserving surgery (BCS) was 51.6%, which declined from 64.5% in 1998 to 39.6% in 2015. The total rate of CPM was 22.7%, which increased from 3.7% in 1998 to 38.7% in 2014 despite a decline to 32.7% in 2015. Meanwhile, the rate of reconstruction increased in line with that of CPM, from 9.4% in 1998 to 35.0% in 2015. There was a trend of increasing use of implant-based reconstruction. Significant higher odds of CPM were found in recent year of diagnosis between 2010 and 2015 and in implant-based reconstruction. Patients undergoing CPM had similar survival outcomes compared with those undergoing BCS and unilateral mastectomy, whereas those undergoing BCS had better survival outcomes compared with those undergoing unilateral mastectomy., Conclusions: A trend of growing preference for CPM and reconstruction was observed among young patients in early stage in recent years without survival benefits. Efforts should be made to promote efficient communication and evidence-based decision-making., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Decisions made to undergo contralateral prophylactic mastectomy, in women at low risk for bilateral disease, are often attributed to a lack of knowledge. This study examines the role knowledge plays in determining surgical treatment for unilateral breast cancer made by laywomen and surgeons for themselves or loved ones., Methods: The study cohort had three groups: (1) laywomen in the general population, (2) breast surgeons, and (3) plastic surgeons. Laywomen were recruited using Amazon Mechanical Turk Crowd Sourcing. Breast and plastic surgeons from nine states were sent electronic surveys. Demographic and contralateral prophylactic mastectomy-specific data on decisions and knowledge were collected and analyzed., Results: Surveys from 1333 laywomen, 198 plastic surgeons, and 142 breast surgeons were analyzed. A significantly greater proportion of laywomen in the general population favored contralateral prophylactic mastectomy (67 percent) relative to plastic (50 percent) and breast surgeons (26 percent) (p < 0.0001). Breast surgeons who chose contralateral prophylactic mastectomy were younger (p = 0.044) and female (0.012). On assessment of knowledge, 78 percent of laywomen had a low level of breast cancer knowledge. Laywomen with higher levels of breast cancer knowledge had lower odds of choosing contralateral prophylactic mastectomy (OR, 0.37; 95 percent CI, 0.28 to 0.49)., Conclusions: Fewer women are likely to make decisions in favor of contralateral prophylactic mastectomy with better breast cancer-specific education. A knowledge gap likely explains the lower rates with which surgeons choose contralateral prophylactic mastectomy for themselves or loved ones; however, some surgeons who were predominantly young and female favor contralateral prophylactic mastectomy. Improving patient education on surgical options for breast cancer treatment is critical, with well-informed decisions as the goal.

Background: The rate of contralateral prophylactic mastectomy (CPM) in women with unilateral mastectomy is increasing with no plateau., Objectives: The aim of this study was to improve the understanding of patient- and tumor-related factors that influenced the choice of mastectomy with CPM as treatment for early-stage breast cancer at an academic medical center in New Jersey., Methods: This was a retrospective analysis of 10 years of breast cancer data including 1556 women aged 40 to 80 years treated for breast cancer at an academic medical center. Logistic regression models identified possible associations between type of surgery and various patient- and tumor-related characteristics., Results: Women most likely to be treated with CPM were younger (P < .0001), white (P = .003), and privately insured (P < .0001). Factors that increased the odds of receiving CPM included year of surgery (odds ratio, 1.441; confidence interval, 1.328-1.564) and residing in a relatively wealthy community (odds ratio, 11.159; confidence interval, 3.467-35.917)., Conclusions: The rate of CPM as a treatment for unilateral breast cancer continues to rise, and this treatment decision seems to be relatively independent of tumor-related factors and clinical evidence of efficacy. More research is needed to ascertain why women are choosing this surgical option., Implications for Practice: The large majority who are choosing CPM are doing so regardless of the lack of clinical efficacy, yet there are few articles in the nursing literature preparing nurses to understand and counsel these women who may be asking for advice. Nurses are well situated to provide unbiased and fact-based information to help women making potentially life-altering decisions in response to a cancer diagnosis.

Purpose: In 2013, Angelina Jolie disclosed in the New York Times (NYT) that she had undergone risk-reducing bilateral mastectomy (RRBM) after learning that she was a BRCA1 mutation carrier. We examined the rates of BRCA testing and RRBM from 1997 to 2016, and quantified trends before and after the Jolie op-ed., Methods: This observational study of insurance claims data representative of the commercially-insured US population (Truven MarketScan® database) measured BRCA testing and RRBM rates among females ≥ 18 years. Censoring events were breast cancer or ovarian cancer diagnosis, last follow-up date (September 2016), or death. Interrupted time series analyses were used to quantify trends before and after the op-ed., Results: Angelina Jolie's NYT op-ed led to a statistically significant increase in the uptake of genetic testing and in RRBM among women without previous diagnosis of breast or ovarian cancer in the US population, and in women who did not undergo testing for BRCA (P < 0.0001 for both). The rate (slope) of RRBM among women who were previously tested for BRCA (P = 0.70) was unchanged. After excluding women with in-situ tumors, the editorial's effect became less pronounced, suggesting that high-risk women with in-situ breast cancers were most influenced by Jolie's announcement., Conclusion: The Angelina Effect-a term coined by Time magazine to describe the rise in internet searches related to breast cancer genetics and counseling-represents a long-lasting impact of celebrity on public health awareness as significant increases in genetic testing and mastectomy rates were observed and sustained in subsequent years.

Women who inherit a mutated copy of the BRCA gene have a higher lifetime risk of developing breast cancer. No large epidemiological studies exist looking at BRCA mutation carriers in UK populations. All patients with BRCA1/BRCA2 mutation identified between 1995 and 2015 were included. Individuals were identified from a prospectively gathered data base. Genetics case-notes were obtained and retrospective analysis performed. 581 female BRCA mutation carriers were identified with a median age of 34 (18-81) at the time of testing. Of the 301 women who underwent diagnostic testing (symptomatic) 246 had been diagnosed with breast cancer, 89 with ovarian cancer and 37 had both at time of testing. Median age at diagnostic test was 51 (25-81). 33% of women underwent risk-reducing mastectomies (RRM); median age at surgery 45. This compares with 37% of women in this diagnostic group who underwent Risk-reducing bilateral salpingo-oopherectomies (RRBSO) at a median age of 46. Two hundred and eighty women underwent predictive testing (family history, asymptomatic), median age 36 (18-81). 34% of women in this predictive group underwent RRM, median age 37. There was a 29% uptake of RRBSO (median age 44 years). Fifteen women (5%) developed breast cancer after being tested; none of these had undergone RRS. This unique study of all BRCA mutation carriers in Wales shows considerable variation in uptake of RRS. The decision to undergo RRS is complex and involves a number of factors, including a woman's age and life stage. As BRCA testing becomes more frequent and more gene mutation carriers are identified there will be significant implications for service allocation, screening demands, and provision of risk-reducing surgery for this high-risk patient group., (© 2017 Wiley Periodicals, Inc.)

Background and Objectives: The purpose of this study was to determine charges following unilateral mastectomy (UM) and bilateral mastectomy (BM) for patients with unilateral breast cancer (UBC). We hypothesized that BM may be associated with fewer charges over time., Methods: A retrospective review was conducted of patients with UBC treated between 2006 and 2010 with UM and BM in a large healthcare system. Institutional billing data were investigated for 5 years postoperatively to calculate the immediate and subsequent charges of all inpatient and outpatient breast-related care associated with the initial diagnosis for a subset of patients identified using propensity score matching method., Results: A subset of matched patients (n = 320) undergoing UM (n = 160) or BM (n = 160) were included in this analysis. At 1 year, there was a trend toward lower total charges following UM as compared with BM (median, $125 230 vs $138 467; P = .6075). However, during years 2 to 5, total charges were significantly higher following UM vs BM ($22 128 vs $13 478; P = .0116)., Conclusions: While initially higher, overall charges for BM are lower than UM between 2 and 5 years out from surgery. Further study is necessary to determine if this trend is sustained over the long term. These data can inform patient decision making regarding mastectomy for their breast cancer., (© 2018 Wiley Periodicals, Inc.)

Background: Recent literature reports that rates of mastectomy are increasing in early breast cancer. However, data from European institutions are limited and revealed conflicting results. We report on 15-year trends of mastectomy, mastectomy plus immediate reconstruction and contralateral prophylactic mastectomy (CPM) at an academic institution., Methods: We identified women diagnosed with unilateral early breast cancer at stage 0-IIa, with tumour size ≤ 4 cm, between 2002 and 2016. Trends were assessed using the Cochrane-Armitage test. Multivariable logistic regression was used to identify factors associated with receipt of mastectomy plus immediate reconstruction., Results: A total of 2315 patients were identified. Of them, 65.7% underwent breast conserving surgery (BCS), while 34.3% underwent mastectomy as upfront surgery. Two point four per cent also received CPM. Immediate reconstruction was performed in 36.0% of patients receiving mastectomy. There was no change in trends of mastectomy over the 15 years studied (p = 0.69), as well as in trends of patients undergoing CPM (p = 0.44). In contrast, rates of immediate reconstruction rose significantly over the study period (from 12.2% in 2002 to 62.7% in 2016, p < 0.0001). Women were more likely to receive mastectomy plus immediate reconstruction if they were aged 50 years or younger, or had tumours larger than 2 cm, or had non-invasive carcinoma., Conclusions: Our study suggests that rates of both mastectomy and CPM in early breast cancer are not increasing, while use of immediate reconstruction is on the rise., (Copyright © 2018 Elsevier Ltd.

Introduction: Contralateral prophylactic mastectomy (CPM) rates are rising, with fear implicated as a contributing factor. This study used a contralateral breast cancer (CBC) risk stratification tool to assess whether the selection of CPM is reflective of future CBC risk., Patients and Methods: This retrospective study evaluated 404 women with unilateral breast cancer treated with breast conservation, unilateral mastectomy, or bilateral mastectomy within a single multidisciplinary clinic. Women were evaluated by the Manchester risk tool to calculate lifetime CBC risk. Logistic regression analysis was used to evaluate whether CBC risk was associated with CPM, and the clinical rationale for prophylactic mastectomy justification was recorded., Results: Sixty-two percent underwent breast conservation, 18% unilateral mastectomy, and 20% bilateral mastectomy. In the CPM cohort, 36% had > 20% calculated lifetime CBC risk. In the invasive cohort, younger age (odds ratio 2.65, P < .0001) and genetic mutation positivity (odds ratio 35.39, P = .019) independently predicted CPM. Other contributing factors included benign contralateral breast findings (29%) and recommendations against breast conservation due to disease burden (28%). Six percent selected CPM as a result of an unsubstantiated fear regarding breast cancer., Conclusion: The majority of women (63%) who selected CPM had < 20% CBC risk. In these lower-risk women selecting CPM, factors increasing reasonable fear dominated surgical choice (81% of this subset)., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: There is an established relationship between hormone receptor (HR; estrogen and/or progesterone receptors) status, HER2 status, and locoregional recurrence. The purpose of this study was to analyze how HR and HER2 receptor status have influenced the surgical management trends among patients with early stage breast cancer., Patients and Methods: The National Cancer Database was queried for patients with cT1 to cT3, cN0, and cM0 breast carcinoma from 2004 to 2012. Patients were grouped on the basis of receptor status and surgical management (mastectomy or breast-conserving surgery [BCS]). Multivariable analyses were performed to investigate factors associated with increased odds of receiving mastectomy over BCS. Among a subgroup of patients who underwent ipsilateral mastectomy, analyses were performed to determine any association between contralateral prophylactic mastectomy (CPM) and receptor status., Results: We found 280,241 patients who met inclusion criteria for analyzing mastectomy or BCS surgical decision. Patients with HER2-positive (HER2 + ) tumors (HR + /HER + and HR - /HER2 + ) were the most likely to undergo mastectomy (odds ratio [OR], 1.212 and 1.499 respectively, compared with HR + /HER2 - patients, each P < .001). HR status alone did not affect ipsilateral surgical management as patients with HR + /HER2 - and HR - /HER2 - tumors demonstrated similar mastectomy rates (P = .391). Among the 108,018 who underwent mastectomy, 20% underwent CPM. After adjustment, patients with HR + /HER2 + , HR - /HER2 + , and HR - /HER2 - were all more likely to undergo CPM (OR 1.356, 1.608, and 1.358, respectively compared with HR + /HER2 - patients, each P < .001)., Conclusion: This analysis indicates that patients with early stage breast cancer are more likely to undergo a mastectomy and CPM if they have HER2 + tumors., (Copyright © 2017 Elsevier Inc.

Purpose: We sought to determine to what extent the knowledge of carrying a BRCA1 or BRCA2 mutation influences the uptake of preventive surgeries in Bahamian women, including bilateral salpingo-oophorectomy and bilateral mastectomy., Patients and Methods: The study population consisted of 78 female residents of the Bahamas for whom a BRCA1 or BRCA2 mutation had been detected between 2004 and 2014. The mean age of the 78 participants at the time of genetic testing was 46 years (age range 22-73 years). The mean time of follow-up was 4.4 years., Results: Of the 78 study participants, 19 women had a bilateral salpingo-oophorectomy (24%). Seven out of 37 patients who had unilateral breast cancer chose to remove the unaffected contralateral breast (19%). Three of 13 patients with no history of breast cancer chose to have a prophylactic bilateral mastectomy (23%)., Conclusion: Preventive surgery is an acceptable option for a significant proportion of Bahamian women with a BRCA1 or BRCA2 mutation. It will be important to identify and reduce barriers to preventive surgery in the Bahamas in order that the benefit of getting testing can be fully realized., (© 2017 The Authors.

Objective: The objective of this study was to explore the influences on decision-making of younger women (<35) undergoing or considering bilateral prophylactic mastectomy (BPM)., Methods: Qualitative interviews guided by interpretative phenomenological analysis (IPA) were conducted with forty-six women who had a strong family history of breast cancer (BC) who had either undergone (n=26) or were considering (n=20) BPM. Participants were recruited from Australia and New Zealand (NZ) via hospitals, a genetics clinic, a research cohort, a registry and online., Results: Four themes underpinning the influences on decision-making were identified: fear and anxiety, children, personal experiences with BC, health professional's influence., Conclusions: The decision to undergo BPM for younger women (<35) was multifaceted, however, it appeared that fear and anxiety were the main influence. Younger women appear more anxious than previous research with older women. There appears to be few differences between those with confirmed BRCA1/2 mutations and those with no known mutation and this is clinically significant., Practice Implications: These findings have important practice implications, particularly improving communication of risk statistics, especially to those with no known mutation. Health professionals need to take into account the way younger women perceive information given to them when discussing risk., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Importance: Rates of contralateral prophylactic mastectomy (CPM) have markedly increased but we know little about the influence of surgeons on variability of the procedure in the community., Objective: To quantify the influence of the attending surgeon on rates of CPM and clinician attitudes that explained it., Design, Setting, and Participants: In this population-based survey study, we identified 7810 women with stages 0 to II breast cancer treated in 2013 to 2015 through the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles County. Surveys were sent approximately 2 months after surgery. Surveys were also sent to 488 attending surgeons identified by the patients., Main Outcomes and Measures: We conducted multilevel analyses to examine the impact of surgeon influence on variations in patient receipt of CPM using information from patient and surgeon surveys merged to Surveillance, Epidemiology, and End Results data., Results: A total of 5080 women responded to the survey (70% response rate), and 377 surgeons responded (77% response rate). The mean (SD) age of responding women was 61.9 (11) years; 28% had an increased risk of second primary cancer, and 16% received CPM. Half of surgeons (52%) practiced for more than 20 years and 30% treated more than 50 new patients with breast cancer annually. Attending surgeon explained a large amount (20%) of the variation in CPM, controlling for patient factors. The odds of a patient receiving CPM increased almost 3-fold (odds ratio, 2.8; 95% CI, 2.1-3.4) if she saw a surgeon with a practice approach 1 SD above a surgeon with the mean CPM rate (independent of age, diagnosis date, BRCA status, and risk of second primary). One-quarter (25%) of the surgeon influence was explained by attending attitudes about initial recommendations for surgery and responses to patient requests for CPM. The estimated rate of CPM was 34% for surgeons who least favored initial breast conservation and were least reluctant to perform CPM vs 4% for surgeons who most favored initial breast conservation and were most reluctant to perform CPM., Conclusions and Relevance: In this study, attending surgeons exerted influence on the likelihood of receipt of CPM after a breast cancer diagnosis. Variations in surgeon attitudes about recommendations for surgery and response to patient requests for CPM explain a substantial amount of this influence.

The objective of this study was to explore the factors that influence perceived personal risk of developing breast cancer (BC) in younger women (<35) who are considering or have undergone bilateral prophylactic mastectomy (BPM). Qualitative interviews guided by interpretative phenomenological analysis were conducted with 46 women who had a strong family history of BC and had either undergone (n = 26) or were considering (n = 20) BPM. Participants were recruited from Australia and New Zealand via hospitals, a genetics clinic, a research cohort, a registry and online. Three main themes were identified: information that increases fear of BC and death, underlying anxiety and fear and screening anxiety. A further two themes: relief following surgery and confusion about residual risk following surgery were identified. Younger women (<35) appeared to have heightened and sometimes inaccurate perceptions of their BC risk. They appeared less relieved of anxiety and fear of developing BC by BPM surgery, in comparison to previous research with older women (>40). Those who had undergone BPM seemed more anxious about their risk of developing BC than those who were still considering surgery. This research has important implications for practice, particularly improving communication of accurate risk statistics. Future research should examine why some women interpret information differently and explore the benefits of psychological consultation for very anxious women.

Introduction: We evaluated the impact of travel distance and insurance status on contralateral prophylactic mastectomy (CPM) rates in breast cancer., Methods: We queried the National Cancer Data Base (NCDB) for women >18 years of age with a nonmetastatic primary breast cancer of ductal, lobular, or mixed histology. Patient- and facility-specific CPM rates were calculated based on insurance, race, and distance to treatment center. Standard univariable and multivariable regression analysis was performed., Results: Overall, the CPM rate was 6.5% for the 864,105 patients identified. Most patients traveled <20 miles to a treatment center (79.5%) and had private insurance or Medicare (58.3 and 33.4%, respectively). In general, younger, White, non-Hispanic, and privately insured patients residing further from a treatment center was associated with increased rates of CPM. However, distance to the treatment center and insurance type had a greater absolute impact on rates of CPM for Black and Hispanic patients. Absolute CPM rate increases for patients >100 miles from a treatment center compared with those <20 miles from a treatment center were observed to be greater for Black and Hispanic patients (3.5 and 3.9%, respectively) compared with White and non-Hispanic patients (2.5 and 2.6%). Additionally, further patient travel distance was associated with higher treatment center-specific CPM rates., Conclusion: Increased travel distance is independently associated with increased rates of CPM for all patients and increased facility-specific rates of CPM. Black and Hispanic patients were found to be more vulnerable to the impact of travel distance and insurance status on rates of CPM.

Background: How diagnosis with a variant of uncertain significance (VUS) in a BRCA gene impacts clinical decision-making is not well known., Methods: We queried for all patients attending Mayo Clinic Rochester from 2004 to 2016 who tested positive for BRCA1 or BRCA2 VUS and reviewed patient management choices. Groups were compared by using Wilcoxon rank-sum and Chi-square tests., Results: We identified 97 patients (95 females, 2 males) with BRCA VUS. For patients without cancer history (n = 20), 80% had a mother or sister with breast cancer, and median Tyrer-Cuzick (IBIS) lifetime breast cancer risk score was 27% (range 16-62%). Management included bilateral prophylactic mastectomy (BPM) in 39%, where choice for BPM was significantly associated with IBIS score (median 32 vs. 24%, p = 0.02) and first-degree family history of breast cancer (100 vs. 64%, p = 0.03) but not Gail score or total number of family members with cancer. For patients with breast cancer who had known VUS status prior to surgery (n = 9), the rate of contralateral prophylactic mastectomy (CPM) was 22% compared with 25% without known VUS and 83% with known BRCA pathogenic mutation. In 21 of 97 (22%) patients, the BRCA VUS has been reclassified (95% benign, 5% deleterious)., Conclusions: BRCA VUS carriers with cancer elected surgical choices similar to average-risk breast cancer patients. However, VUS carriers without cancer had high rates of BPM, associated with first-degree family history and IBIS score. Over time, a significant proportion of BRCA VUS were reclassified, illustrating the importance of appropriate counseling regarding VUS.

Introduction: We performed the present study to better understand the practices and preferences of women with an elevated risk of breast cancer by merging the registries from 2 separate institutions and comparing the clinical characteristics and outcomes., Materials and Methods: The data from women enrolled in institutional review board-approved registries from 2003 to 2015 at the New York University Langone Medical Center and University of Vermont Medical Center were evaluated. We compared patient characteristics, risk factors, uptake of prevention methods, and cancer rates between the 2 registries., Results: A total of 1035 women were included in the present analysis. We found a 99% concordance of variables collected between the 2 registries. Significant differences were found in age, risk characteristics, uptake of prevention methods, and cancer rates between the 2 registries. The uptake of chemoprevention was low (8% for all women), with greater uptake among women with atypia found on biopsy examination (66%) than among those with a strong family history or BRCA mutations. Women with BRCA mutations accounted for 76% of those undergoing risk-reducing surgery. Of the 1035 women, 43 (4%) developed breast cancer. Of these, 86% were diagnosed with American Joint Committee on Cancer stage 0 or 1 disease, 95% with tumors < 2 cm, and 70% with poor to moderately differentiated pathologic features. Only 1 of the women who developed breast cancer had been undergoing chemoprevention, and none had undergone previous prophylactic surgery., Conclusion: We found a high degree of concordance between registries, suggesting no barriers exist to multi-institutional collaboration. Overall, a low uptake of prevention opportunities was found in this high-risk population. Women developing breast cancer had predominantly low-stage but higher grade disease, which might suggest a benefit to participation in surveillance (or high-risk) programs., (Copyright © 2017 Elsevier Inc.

Background: The increased uptake of contralateral prophylactic mastectomy (CPM) among breast cancer patients remains poorly understood. We hypothesized that the increased rate of CPM is represented in conversations on an online breast cancer community and may contribute to patients choosing this operation., Methods: We downloaded 328,763 posts and their dates of creation from an online breast cancer community from August 1, 2000, to May 22, 2016. We then performed a keyword search to identify posts which mentioned breast cancer surgeries: contralateral prophylactic mastectomy (n = 7095), mastectomy (n = 10,889), and lumpectomy (n = 9694). We graphed the percentage of CPM-related, lumpectomy-related, and mastectomy-related conversations over time. We also graphed the frequency of posts which mentioned multiple operations over time. Finally, we performed a qualitative study to identify factors influencing the observed trends., Results: Surgically related posts (e.g., mentioning at least one operation) made up a small percentage (n = 27,678; 8.4%) of all posts on this community. The percentage of surgically related posts mentioning CPM was found to increase over time, whereas the percentage of surgically related posts mentioning mastectomy decreased over time. Among posts that mentioned more than one operation, mastectomy and lumpectomy were the procedures most commonly mentioned together, followed by mastectomy and CPM. There was no change over time in the frequency of posts that mentioned more than one operation. Our qualitative review found that most posts mentioning a single operation were unrelated to surgical decision-making; rather the operation was mentioned only in the context of the patient's cancer history. Conversely, the most posts mentioning multiple operations centered around the patients' surgical decision-making process., Conclusions: CPM-related conversation is increasing on this online breast cancer community, whereas mastectomy-related conversation is decreasing. These results appear to be primarily informed by patients reporting the types of operations they have undergone, and thus appear to correspond to the known increased uptake of CPM., (Copyright © 2017 Elsevier Inc.

Purpose: Rates of contralateral prophylactic mastectomy (CPM) have increased over the last decade; it is important for surgeons and hospital systems to understand the economic drivers of increased costs in these patients. This study aims to identify factors affecting charges in those undergoing CPM and reconstruction., Methods: Analysis of the Healthcare Cost and Utilization Project National Inpatient Sample was undertaken (2009-2012), identifying women aged ≥18 with unilateral breast cancer undergoing unilateral mastectomy with CPM and immediate breast reconstruction (IBR) (CPM group), in addition to unilateral mastectomy and IBR alone (UM group). Generalized linear modeling with gamma regression and a log-link function provided mean marginal hospital charge (MMHC) estimates associated with the presence or absence of patient, hospital and operative characteristics, postoperative complications, and length of stay (LOS)., Results: Overall, 70,695 women underwent mastectomy and reconstruction for unilateral breast cancer; 36,691 (51.9%) in the CPM group, incurring additional MMHCs of $20,775 compared to those in the UM group (p < 0.001). In the CPM group, MMHCs were reduced in those aged >60 years (p < 0.001), while African American or Hispanic origin increased MMHCs (p < 0.001). Diabetes, depression, and obesity increased MMHCs (p < 0.001). MMHCs increased with larger (p < 0.001) hospitals, Western location (p < 0.001), greater household income (p < 0.001), complications (p < 0.001), and increasing LOS (p < 0.001). MMHCs decreased in urban teaching hospitals and Midwest or Southern regions (p < 0.001)., Conclusion: There are many patient and hospital factors affecting charges; this study provides surgeons and hospital systems with transparent, quantitative charge data in patients undergoing contralateral prophylactic mastectomy and immediate breast reconstruction.

Importance: The use of contralateral prophylactic mastectomies (CPMs) among patients with invasive unilateral breast cancer has increased substantially during the past decade in the United States despite the lack of evidence for survival benefit. However, whether this trend varies by state or whether it is correlated with changes in proportions of reconstructive surgery among these patients is unclear., Objective: To determine state variation in the temporal trend and in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery., Design, Setting, and Participants: A retrospective cohort study of 1.2 million women 20 years of age or older diagnosed with invasive unilateral early-stage breast cancer and treated with surgery from January 1, 2004, through December 31, 2012, in 45 states and the District of Columbia as compiled by the North American Association of Central Cancer Registries. Data analysis was performed from August 1, 2015, to August 31, 2016., Exposure: Contralateral prophylactic mastectomy., Main Outcomes and Measures: Temporal changes in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery by age and state, overall and in relation to changes in the proportions of those who underwent reconstructive surgery., Results: Among the 1 224 947 women with early-stage breast cancer treated with surgery, the proportion who underwent a CPM nationally increased between 2004 and 2012 from 3.6% (4013 of 113 001) to 10.4% (12 890 of 124 231) for those 45 years or older and from 10.5% (1879 of 17 862) to 33.3% (5237 of 15 745) for those aged 20 to 44 years. The increase was evident in all states, although the magnitude of the increase varied substantially across states. For example, among women 20 to 44 years of age, the proportion who underwent a CPM from 2004-2006 to 2010-2012 increased from 14.9% (317 of 2121) to 24.8% (436 of 1755) (prevalence ratio [PR], 1.66; 95% CI, 1.46-1.89) in New Jersey compared with an increase from 9.8% (162 of 1657) to 32.2% (495 of 1538) (PR, 3.29; 95% CI, 2.80-3.88) in Virginia. In this age group, CPM proportions for the period from 2010 to 2012 were over 42% in the contiguous states of Nebraska, Missouri, Colorado, Iowa, and South Dakota. From 2004 to 2012, the proportion of reconstructive surgical procedures among women aged 20 to 44 years who were diagnosed with early-stage breast cancer and received a CPM increased in many states; however, it did not correlate with the proportion of women who received a CPM., Conclusions and Relevance: The increase in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery varied substantially across states. Notably, in 5 contiguous Midwest states, nearly half of young women with invasive early-stage breast cancer underwent a CPM from 2010 to 2012. Future studies should examine the reasons for the geographic variation and increasing trend in the use of CPMs.

Background: Breast cancer (BC) disparities may widen with genomic advances. The authors compared non-Hispanic white (NHW), black, and Hispanic BC survivors for 1) cancer risk-management practices among BRCA carriers and 2) provider discussion and receipt of genetic testing., Methods: A population-based sample of NHW, black, and Hispanic women who had been diagnosed with invasive BC at age 50 years or younger from 2009 to 2012 were recruited through the state cancer registry. Multiple logistic regression was used to compare cancer risk-management practices in BRCA carriers and associations of demographic and clinical variables with provider discussion and receipt of testing., Results: Of 1622 participants, 159 of 440 (36.1%) black women, 579 of 897 (64.5%) NHW women, 58 of 117 (49.6%) Spanish-speaking Hispanic women, and 116 of 168 (69%) English-speaking Hispanic women underwent BRCA testing, of whom 90 had a pathogenic BRCA mutation identified. Among BRCA carriers, the rates of risk-reducing mastectomy and risk-reducing salpingo-oophorectomy were significantly lower among black women compared with Hispanic and NHW women after controlling for clinical and demographic variables (P = .025 and P = .008, respectively). Compared with NHW women, discussion of genetic testing with a provider was 16 times less likely among black women (P < .0001) and nearly 2 times less likely among Spanish-speaking Hispanic women (P = .04) after controlling for clinical and sociodemographic factors., Conclusions: The current results suggest that the rates of risk-reducing salpingo-oophorectomy are lower among black BRCA carriers compared with their Hispanic and NHW counterparts, which is concerning because benefits from genetic testing arise from cancer risk-management practice options. Furthermore, lower BRCA testing rates among blacks may partially be because of a lower likelihood of provider discussion. Future studies are needed to improve cancer risk identification and management practices across all populations to prevent the widening of disparities.

Background: Some women of families at high risk of breast cancer (BC) choose prophylactic mastectomy (PM) in spite of ambiguous evidence for survival benefits. The aim of this study was to investigate counselees' characteristics, decisions on PM, and frequencies of different procedures to better understand how to tailor interventions., Patients and Methods: Eight hundred and forty-nine counselees who attended interdisciplinary consultation for genetic risk adjustment at the University Hospital Heidelberg between July 2009 and July 2011 received a tripartite questionnaire addressing sociodemographic characteristics, psychological parameters, behavioural questions, and medical data., Results: Six hundred and twelve of the 849 counselees (72%) returned the questionnaire. Four hundred were classified as high risk of genetic BC (19.5% BRCA mutation carriers; 4% unclassified variant (UV); and 76.5% calculated as high risk by pedigree). Two hundred and thirteen out of 400 (53%) were diagnosed with BC. Fourteen out of 54 (27%) BRCA mutation carriers with BC chose contralateral PM (CPM) compared to 24/126 (14%) without a mutation but with a personal BC history (p = 0.2175). Of those without BC, 12/27 (44%) mutation carriers opted for bilateral PM (BPM) compared to none without a mutation (p < 0.0001). Women who received any PM (CPM and BPM) reported a higher emotional burden from partners (p = 0.003) and family (p = 0.008), more worries regarding children and family (p = 0.003) and were associated with positive mutation status and higher heterozygous and lifetime risk (all p < 0.001)., Conclusion: Although evidence on survival benefit is unclear in several clinical situations, a relevant number of counselees opt for PM. Counselees may decide based on other reasons than survival benefit.

Objective: To update and examine national temporal trends in contralateral prophylactic mastectomy (CPM) and determine whether survival differed for invasive breast cancer patients based on hormone receptor (HR) status and age., Methods: We identified women diagnosed with unilateral stage I to III breast cancer between 1998 and 2012 within the Surveillance, Epidemiology, and End Results registry. We compared characteristics and temporal trends between patients undergoing breast-conserving surgery, unilateral mastectomy, and CPM. We then performed Cox proportional-hazards regression to examine breast cancer-specific survival (BCSS) and overall survival (OS) in women diagnosed between 1998 and 2007, who underwent breast-conserving surgery with radiation (breast-conserving therapy), unilateral mastectomy, or CPM, with subsequent subgroup analysis stratifying by age and HR status., Results: Of 496,488 women diagnosed with unilateral invasive breast cancer, 59.6% underwent breast-conserving surgery, 33.4% underwent unilateral mastectomy, and 7.0% underwent CPM. Overall, the proportion of women undergoing CPM increased from 3.9% in 2002 to 12.7% in 2012 (P < 0.001). Reconstructive surgery was performed in 48.3% of CPM patients compared with only 16.0% of unilateral mastectomy patients, with rates of reconstruction with CPM rising from 35.3% in 2002 to 55.4% in 2012 (P < 0.001). When compared with breast-conserving therapy, we found no significant improvement in BCSS or OS for women undergoing CPM (BCSS: HR 1.08, 95% confidence interval 1.01-1.16; OS: HR 1.08, 95% confidence interval 1.03-1.14), regardless of HR status or age., Conclusions: The use of CPM more than tripled during the study period despite evidence suggesting no survival benefit over breast conservation. Further examination on how to optimally counsel women about surgical options is warranted.

Background: Bilateral prophylactic mastectomy (BPM) has demonstrated breast cancer risk reduction in high-risk/ BRCA + patients. However, priority of active cancers coupled with inefficient use of operating room (OR) resources presents challenges in offering BPM in a timely manner. To address these challenges, a rapid access prophylactic mastectomy and immediate reconstruction (RAPMIR) program was innovated. The purpose of this study was to evaluate RAPMIR with regards to access to care and efficiency., Methods: We retrospectively reviewed the cases of all high-risk/ BRCA + patients having had BPM between September 2012 and August 2014. Patients were divided into 2 groups: those managed through the traditional model and those managed through the RAPMIR model. RAPMIR leverages 2 concurrently running ORs with surgical oncology and plastic surgery moving between rooms to complete 3 combined BPMs with immediate reconstruction in addition to 1-2 independent cases each operative day. RAPMIR eligibility criteria included high-risk/ BRCA + status; BPM with immediate, implant-based reconstruction; and day surgery candidacy. Wait times, case volumes and patient throughput were measured and compared., Results: There were 16 traditional patients and 13 RAPMIR patients. Mean wait time (days from referral to surgery) for RAPMIR was significantly shorter than for the traditional model (165.4 v. 309.2 d, p = 0.027). Daily patient throughput (4.3 v. 2.8), plastic surgery case volume (3.7 v. 1.6) and surgical oncology case volume (3.0 v. 2.2) were significantly greater in the RAPMIR model than the traditional model ( p = 0.003, p < 0.001 and p = 0.015, respectively)., Conclusion: A multidisciplinary model with optimized scheduling has the potential to improve access to care and optimize resource utilization.

Breast-conserving therapy (BCT) and mastectomy result in equivalent long-term survival. Locoregional recurrence rates after BCT have decreased over time and are now similar to those after mastectomy. Contralateral breast cancer rates are declining as well owing to the widespread use of adjuvant systemic therapy. Despite these improved outcomes, increasing rates of bilateral mastectomy for unilateral cancer have been observed in the United States. Medical indications for mastectomy are well defined and present in a minority of patients, and women at increased risk for contralateral cancer are a small proportion of the breast cancer population. Evidence indicates that increasing use of mastectomy is a patient-driven trend that is most pronounced among younger, educated, and well-insured women, and reflects fear of recurrence and in some cases misunderstanding of future cancer risks. Although satisfaction levels are generally high among patients choosing contralateral prophylactic mastectomy, complications and procedure extent may be underestimated. Improved communication strategies are essential to facilitate this complex decision-making process.

Since the results of randomised controlled trials in the last quarter of the twentieth century were reported, it has been conventionally accepted that breast conservation treatment (BCT) provides equivalent survival to mastectomy for early breast cancer. As expected, there was an initial fall in the use of mastectomy. The first decade of the twenty-first century, however, witnessed a trend of increasing mastectomy rates in some regions. This perplexing circumstance served as an impetus for a relook at survival outcomes with each surgical modality. Recent studies have demonstrated higher survival rates and improved local control associated with BCT. Such findings warrant a re-evaluation of treatment strategies, beginning with whether there is an optimum BCT rate.

Purpose: The rate of contralateral prophylactic mastectomies (CPMs) continues to rise, although there is little evidence to support improvement in quality of life (QOL) with CPM. We sought to ascertain whether patient-reported outcomes and, more specifically, QOL differed according to receipt of CPM., Methods: Volunteers recruited from the Army of Women with a history of breast cancer surgery took an electronically administered survey, which included the BREAST-Q, a well-validated breast surgery outcomes patient-reporting tool, and demographic and treatment-related questions. Descriptive statistics, hypothesis testing, and regression analysis were used to evaluate the association of CPM with four BREAST-Q QOL domains., Results: A total of 7,619 women completed questionnaires; of those eligible, 3,977 had a mastectomy and 1,598 reported receipt of CPM. Women undergoing CPM were younger than those who did not choose CPM. On unadjusted analysis, mean breast satisfaction was higher in the CPM group (60.4 v 57.9, P < .001) and mean physical well-being was lower in the CPM group (74.6 v 76.6, P < .001). On multivariable analysis, the CPM group continued to report higher breast satisfaction (P = .046) and psychosocial well-being (P = .017), but no difference was reported in the no-CPM group in the other QOL domains., Conclusion: Choice for CPM was associated with an improvement in breast satisfaction and psychosocial well-being. However, the magnitude of the effect may be too small to be clinically meaningful. Such patient-reported outcomes data are important to consider when counseling women contemplating CPM as part of their breast cancer treatment., (© 2016 by American Society of Clinical Oncology.)
