Abstract
Approximately 11% of all new breast cancer cases annually are diagnosed in young women, and this continues to be the leading cause of death in women age 20 to 49. Young, premenopausal breast cancer patients present with more advanced stages and with a higher proportion of aggressive subtypes such as triple negative and HER2-enriched tumors. Recently, the United States Preventive Services Task Force (USPSTF) lowered the age threshold to initiate screening mammograms to age 40 to aid in earlier detection. Young age at diagnosis increases the likelihood for a pathogenic mutation, and genetic testing is recommended for all patients age 50 and younger. This population is often underrepresented in landmark clinical trials, and data is extrapolated for the treatment of young women with breast cancer. Despite there being no survival benefit to more extensive surgical treatments, such as mastectomy or contralateral prophylactic mastectomy, many patients opt against breast conservation. Young patients with breast cancer face issues related to treatment toxicities, potential overtreatment of their disease, mental health, sexual health, and fertility preservation. This unique population requires a multidisciplinary care team of physicians, surgeons, genetic counselors, fertility specialists, mental health professionals, physical therapists, and dieticians to provide individualized, comprehensive care. Our aim is to (1) provide a narrative review of retrospective studies, relevant society guidelines, and clinical trials focused on the contemporary treatment and management of YBC patients and (2) discuss important nuances in their care as a guide for members of their multidisciplinary treatment team.

Universal Germline-Genetic Testing for Breast Cancer: Implementation in a Rural Practice and Impact on Shared Decision-Making. Ann Surg Oncol 2024; 31:325-334. [PMID: 37814187 PMCID: PMC10695880 DOI: 10.1245/s10434-023-14394-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 09/15/2023] [Indexed: 10/11/2023]
Abstract
BACKGROUND Whereas the National Comprehensive Cancer Network (NCCN) criteria restrict germline-genetic testing (GGT) to a subset of breast cancer (BC) patients, the American Society of Breast Surgeons recommends universal GGT. Although the yield of pathogenic germline variants (PGV) in unselected BC patients has been studied, the practicality and utility of incorporating universal GGT into routine cancer care in community and rural settings is understudied. This study reports real-world implementation of universal GGT for patients with breast cancer and genetics-informed, treatment decision-making in a rural, community practice with limited resources. METHODS From 2019 to 2022, all patients with breast cancer at a small, rural hospital were offered GGT, using a genetics-extender model. Statistical analyses included Fisher's exact test, t-tests, and calculation of odds ratios. Significance was set at p < 0.05. RESULTS Of 210 patients with breast cancer who were offered GGT, 192 (91.4%) underwent testing with 104 (54.2%) in-criteria (IC) and 88 (45.8%) out-of-criteria (OOC) with NCCN guidelines. Pathogenic germline variants were identified in 25 patients (13.0%), with PGV frequencies of 15 of 104 (14.4%) in IC and ten of 88 (11.4%) in OOC patients (p = 0.495). GGT informed treatment for 129 of 185 (69.7%) patients. CONCLUSIONS Universal GGT was successfully implemented in a rural, community practice with > 90% uptake. Treatment was enhanced or de-escalated in those with and without clinically actionable PGVs, respectively. Universal GGT for patients with breast cancer is feasible within rural populations, enabling optimization of clinical care to patients' genetic profile, and may reduce unnecessary healthcare, resource utilization.

Patient-driven decisions and perceptions of the 'safest possible choice': insights from patient-provider conversations about how some breast cancer patients choose contralateral prophylactic mastectomy. Psychol Health 2023:1-25. [PMID: 38044547 DOI: 10.1080/08870446.2023.2290170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 11/27/2023] [Indexed: 12/05/2023]
Abstract
OBJECTIVE Observe patient-clinician communication to gain insight about the reasons underlying the choice of patients with unilateral breast cancer to undergo contralateral prophylactic mastectomy (CPM), despite lack of survival benefit, risk of harms, and cautions expressed by surgical guidelines and clinicians. METHODS & MEASURES WORDS is a prospective study that explored patient-clinician communication and patient decision making. Participants recorded clinical visits through a downloadable mobile application. We analyzed 44 recordings from 22 patients: 9 who chose CPM, 8 who considered CPM but decided against it, and 5 who never considered CPM. We used abductive analysis combined with constructivist grounded theory methods. RESULTS Decisions to undergo CPM are patient-driven and motivated by perceptions that CPM is the most aggressive, and therefore safest, treatment option available. These decisions are shaped not primarily by the content of conversations with clinicians, but by the history of cancer in patients' families, their own first-hand experiences with cancers among loved ones, fear for their children, and anxiety about cancer recurrence. CONCLUSION The perception that CPM is the safest, most aggressive option strongly influences patients, despite scientific evidence to the contrary. Future efforts to address high CPM rates should focus on patient-driven decision making and cancer-related fears.

Association of Moderate-Risk Breast Cancer Genes with Contralateral Prophylactic Mastectomy and Bilateral Disease. Ann Surg Oncol 2023; 30:6990-6999.

Abstract
BACKGROUND The impact of ATM, CHEK2, and PALB2, the three most prevalent moderate-risk breast cancer genes, on surgical decision making is not well known. METHODS Our retrospective study included patients with resectable non-metastatic breast cancer who underwent multigene panel testing between July 2014 and January 2020 with at least one genetic alteration (pathogenic or variant of uncertain significance [VUS] in ATM [n = 49], CHEK [n = 57], or PALB2 [n = 27]). Our objectives were to determine the rate of contralateral prophylactic mastectomy (CPM) and the rate of bilateral breast cancer. Univariable analyses (UVA) and multivariable analyses (MVA) were performed to identify factors associated with CPM and bilateral breast cancer. RESULTS The rate of CPM was 39% (n = 49/127), with 54% (n = 25/46) of patients with a pathogenic mutation and 30% (n = 24/81) of patients with a VUS choosing CPM. On MVA, premenopausal status (odds ratio [OR] 3.46) and a pathogenic alteration (OR 3.01) were associated with increased use of CPM. Bilateral disease was noted in 16% (n = 22/138). Patients with pathogenic mutations had a 22% (n = 11/51) incidence of bilateral breast cancer, while patients with VUS had a 13% (n = 11/87) incidence, although this was not statistically significant on UVA or MVA. On MVA, premenopausal status was associated with a decreased risk of bilateral disease (OR 0.33, p = 0.022). During follow-up, a breast cancer event occurred in 16% (n = 22/138). CONCLUSIONS Our study identified a high rate of CPM among those with ATM, CHEK2, and PALB2 alterations, including VUS. Further studies are needed to clarify reasons for CPM among patients with moderate-risk alterations.

Abstract
Background: To describe the indications and outcomes of BRCA mutation carriers undergoing nipple-sparing mastectomy (NSM). Methods: In this retrospective study, 76 BRCA mutation carriers with no cancer who opted to undergo risk reduction NSM or diagnosed with breast cancer (BC) who opted to undergo therapeutic NSM were included. Results: Indications for NSM: cancer treatment (n = 33), bilateral risk reduction (n = 39) and contralateral prophylactic NSM (n = 4). In a mean follow-up of 45 months (median: 30 months), one patient (2.5%) undergoing risk-reducing NSM developed a new BC. One (3%) local, one (3%) ipsilateral axillary and one (3%) distant recurrence were observed in BC patients. No partial or total nipple necrosis occurred. Conclusion: NSM is safe for reducing the risk of BC development in BRCA mutation carriers and for treating cancer.

Abstract
OBJECTIVE The ATM gene is one of the most common breast cancer (BC) susceptibility genes after BRCA1/2 and has been shown to be a moderate BC susceptibility gene. The association between ATM germline mutation and clinical features of BC is now unknown. In this article, clinicopathological features of BC patients with ATM germline heterozygous mutation were investigated. MATERIALS AND METHODS Patients admitted to the Medical Genetics department of a tertiary hospital between January 2020 and December 2022 were examined. Only invasive BC patients with pathogenic mutation, likely pathogenic mutation, or variants of uncertain significance (VUS) were included in the study. RESULTS In all, 121 patients were included in the study. The median age at the first cancer diagnosis of the patients was 44 years. Of the total number of patients, 75.2% (91) had the histological subtype of infiltrating ductal carcinoma, and 43% (52) had Luminal B molecular subtype features. At a median follow-up of 16 months, 5.8% (7) of patients developed cancer in the contralateral breast. In addition, 7.4% (9) of the patients developed a second primary cancer during follow-up. When the patients were compared according to ATM variant classification, the localization, histologic types, and molecular subtypes of the BC were not different between all groups (respectively; p=0.68, p=0.65, p=0.32). CONCLUSIONS To the best of our knowledge, this is the first publication that evaluates the clinical and pathological characteristics of BC patients with germline heterozygous ATM mutations in the Turkish population. When patients were compared according to variant classifications of ATM mutation, patients' histological and molecular subtypes were similar.

Abstract
BACKGROUND Contralateral prophylactic mastectomy (CPM) has been performed for several decades in patients with unilateral breast cancer (BC). However, the survival benefits of CPM are controversial, particularly in young women. MATERIALS AND METHOD In this retrospective study, the clinical total of 69,000 young female patients (age ≤ 40 years) who were diagnosed to have unilateral BC and underwent unilateral mastectomy (UM) or CPM between January 1, 2000 and December 31, 2019 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was performed to minimize selection bias and overcome differences in tumor characteristics between the CPM and UM groups. Overall survival (OS) and BC-specific survival (BCSS) were assessed using Kaplan-Meier curves and compared across groups using log-rank test. Multivariable Cox proportional hazards regression analysis was performed to estimate hazard ratios (HRs). RESULTS A total of 36,528 patients (21,600 and 14,928 patients in the UM and CPM groups, respectively) were included in follow study. The CPM group showed a higher 5-year OS rate (82.1% vs. 75.8%) and a higher 5-year BCSS rate (83.5% vs. 77.7%) than the UM group. Multivariate Cox analysis after PSM (n = 13,089) showed that CPM significantly decreased 25% risk of all-cause mortality (OS, HR: 0.75, 95% confidence interval [CI]: 0.70-0.80; P < .001) and 25% risk of BC-specific mortality (BCSS, HR: 0.75, 95% CI: 0.70-0.80; P < .001) in young BC patients as compared to UM. CONCLUSION This study suggests that CPM improved OS and BCSS benefits in young BC patients as compared to UM. Randomized clinical trials with a larger sample size are required in the future to confirm these results.

Abstract
This study aims to assess potential complications and effects on the magnetic resonance imaging (MRI) image quality of a new MRI-conditional breast tissue expander (Motiva Flora®) in its first in-human multi-case application. Twenty-four patients with 36 expanders underwent non-contrast breast MRI with T1-weighted, T2-weighted, and diffusion-weighted imaging (DWI) sequences on a 3 T unit before breast tissue expander exchange surgery, being monitored during and after MRI for potential complications. Three board-certified breast radiologists blindly and independently reviewed image quality using a four-level scale ("poor", "sufficient", "good", and "excellent"), with inter-reader reliability being assessed with Kendall's τb. The maximum diameters of RFID-related artifacts on T1-weighted and DWI sequences were compared with the Wilcoxon signed-rank test. All 24 examinations were completed without patient-related or device-related complications. The T1-weighted and T2-weighted sequences of all the examinations had "excellent" image quality and a median 11 mm (IQR 9-12 mm) RFID artifact maximum diameter, significantly lower (p < 0.001) than on the DWI images (median 32.5 mm, IQR 28.5-34.5 mm). DWI quality was rated at least "good" in 63% of the examinations, with strong inter-reader reliability (Kendall's τb 0.837, 95% CI 0.687-0.952). This first in-human study confirms the MRI-conditional profile of this new expander, which does not affect the image quality of T1-weighted and T2-weighted sequences and moderately affects DWI quality.

Abstract
For patients with newly diagnosed breast cancer, information regarding hereditary predisposition can influence treatment decisions. From a surgical standpoint, patients with known germline mutations may alter decisions of local therapy to reduce the risk of second breast primaries. This information may also be considered in the choice of adjuvant therapies or eligibility for clinical trials. In recent years, the criteria for the consideration of germline testing in patients with breast cancer has expanded. Additionally, studies have shown a similar prevalence of pathogenic mutations in those patients outside of these traditional criteria, prompting calls for genetic testing for all patients with a history of breast cancer. While data confirms the benefit of counseling by certified genetics professionals, the capacity of genetic counselors may no longer meet the needs of these growing numbers of patients. National societies assert that counseling and testing can be performed by providers with training and experience in genetics. Breast surgeons are well positioned to offer this service, as they receive formal genetics training during their fellowship, manage these patients daily in their practices, and are often the first providers to see patients after their cancer diagnosis.

Risk‐reducing mastectomy decisions among women with mutations in high‐ and moderate‐ penetrance breast cancer susceptibility genes. Mol Genet Genomic Med 2022; 10:e2031.

Abstract
Background Women harboring mutations in breast cancer susceptibility genes are at increased lifetime risk of developing breast cancer and are faced with decisions about risk management, including whether to undergo high‐risk screening or risk‐reducing mastectomy (RRM). National guidelines recommend BRCA1 or BRCA2 mutation carriers consider RRM, but that carriers of moderate penetrance mutations (e.g., ATM or CHEK2) should be managed based on family history. We aimed to investigate determinants of decision for RRM, and hypothesized that mutation status, age, family history, partner status, and breast cancer would impact RRM decision making. Methods We performed a retrospective study assessing RRM decisions for 279 women. Results Women with BRCA and moderate penetrance gene mutations, a personal history of breast cancer, or a first degree relative with a history of breast cancer were more likely to undergo RRM. Breast cancer status and age showed an interaction effect such that women with breast cancer were less likely to undergo RRM with increasing age. Conclusion Although national guidelines do not recommend RRM for moderate penetrance carriers, the rates of RRM for this population approached those for BRCA mutation carriers. Further insights are needed to better support RRM decision‐making in this population.

Dettwyler SA, Thull DL, McAuliffe PF, Steiman JG, Johnson RR, Diego EJ, Mai PL. Timely cancer genetic counseling and testing for young women with breast cancer: impact on surgical decision-making for contralateral risk-reducing mastectomy. Breast Cancer Res Treat 2022; 194:393-401. [PMID: 35596825 DOI: 10.1007/s10549-022-06619-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 04/25/2022] [Indexed: 01/02/2023]
Abstract
PURPOSE Genetic testing (GT) can identify individuals with pathogenic/likely pathogenic variants (PV/LPVs) in breast cancer (BC) predisposition genes, who may consider contralateral risk-reducing mastectomy (CRRM). We report on CRRM rates in young women newly diagnosed with BC who received GT through a multidisciplinary clinic. METHODS Clinical data were reviewed for patients seen between November 2014 and June 2019. Patients with non-metastatic, unilateral BC diagnosed at age ≤ 45 and completed GT prior to surgery were included. Associations between surgical intervention and age, BC stage, family history, and GT results were evaluated. RESULTS Of the 194 patients, 30 (15.5%) had a PV/LPV in a BC predisposition gene (ATM, BRCA1, BRCA2, CHEK2, NBN, NF1), with 66.7% in BRCA1 or BRCA2. Of 164 (84.5%) uninformative results, 132 (68%) were negative and 32 (16.5%) were variants of uncertain significance (VUS). Overall, 67 (34.5%) had CRRM, including 25/30 (83.3%) PV/LPV carriers and 42/164 (25.6%) non-carriers. A positive test result (p < 0.01) and significant family history were associated with CRRM (p = 0.02). For the 164 with uninformative results, multivariate analysis showed that CRRM was not associated with age (p = 0.23), a VUS, (p = 0.08), family history (p = 0.10), or BC stage (p = 0.11). CONCLUSION In this cohort of young women with BC, the identification of a PV/LPV in a BC predisposition gene and a significant family history were associated with the decision to pursue CRRM. Thus, incorporation of genetic services in the initial evaluation of young patients with a new BC could contribute to the surgical decision-making process.

Abstract
Abstract
Introduction
Although central breast cancer is not a contraindication to breast conserving, most surgeons still choose to perform total mastectomy. The safety of breast conserving treatment for central breast cancer is still unclear. The purpose of this study is to evaluate the long-term survival outcome of central breast cancer.
Materials and methods
Using SEER database to explore the trend of surgical procedures for patients with central breast cancer. The patients were divided into breast conserving group and non-breast conserving group. Multivariate logistic regression was used to evaluate predictors of breast conserving surgery in central breast cancer. The clinicopathological variables were adjusted through the multivariable Cox risk model, and the stage and T stage were stratified to compare survival results.
Results
A total of 8702 patients with central breast cancer underwent surgical treatment from 2010 to 2015. There were 3870 patients in the breast conserving group and 4832 patients in the non-breast conserving group. The breast preservation rate was 44.4%, which rose from 39.9% in 2010 to 51% in 2015. Elderly patients (p < 0.001) and low tumor malignancy were predictors of breast conserving therapy. In the 1:1 matched case–control analysis, breast cancer-specific survival (BCSS) (p < 0.001) and overall survival (OS) (p < 0.001) in breast conserving therapy group were still higher than those of non-breast conserving. In the subgroup analysis of T staging and stage, the breast conserving therapy group still had higher OS and BCSS.
Conclusion
In central breast cancer, breast-conserving therapy is safe and optional.

Contralateral prophylactic mastectomy in the setting of breast cancer diagnosis and their insurance coverage in the United States. Breast J 2021; 27:746-752. [PMID: 34528334 DOI: 10.1111/tbj.14280] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 08/02/2021] [Accepted: 08/04/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND Contralateral prophylactic mastectomy (CPM) is more common in the United States than the rest of the world. However, the benefit of this procedure is still under question in many breast cancer scenarios. CPM utilization in the United States is in part dependent on a patient's health insurance coverage of breast oncology surgery and any desired reconstruction. However, there are great discrepancies in the coverage provided by insurers. METHODS The authors conducted a cross-sectional analysis of insurance policies for a CPM in the setting of diagnosed breast cancer. One hundred companies were selected based on their state enrollment and market share. Their policies were identified through a Web-based search and telephone interviews, and their medical necessity criteria were extracted. RESULTS Of the 100 companies assessed, 36 (36%) had a policy for CPM. Within those, significantly more provided coverage than denied the procedure (72% vs. 25%, p < 0.0001), with the remainder providing case-by-case coverage. Eleven criteria were identified from preauthorized policies, the most common prerequisite was breast cancer diagnosis under 45 years old (n = 9, 35%). Most policies did not differentiate between gender in their policies (n = 25, 69%), but of those that did, 100% (n = 11) provided coverage for men and women, with 82% (n = 9) requiring further criteria from the female patients. CONCLUSION The coverage of CPM in the United States varies from complete denial to unrestricted approval. This may be due to conflicting reports in the literature as to the utility of the procedure. The decision to undergo this procedure must be taken with thoughtful consideration and the support of a multidisciplinary approach.

Cancers (Basel) 2021; 13:cancers13133294. [PMID: 34209279 PMCID: PMC8267737 DOI: 10.3390/cancers13133294] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 06/21/2021] [Accepted: 06/23/2021] [Indexed: 12/12/2022] Open
Abstract
Simple Summary This study aimed to prove the early presence of circulating tumor cells (CTCs) with viability and tumorigenesis in a murine model that spontaneously develops breast cancer. Serial CTC examinations were performed on NeuN transgenic mice, starting from the age of 8 weeks and continuing after palpable tumor formation. Prior to the detection of palpable tumors, the CTC counts rose over time from 1 ± 1.6 to 16 ± 9.5 per 75 μL; this number continued to grow with tumor development. The viability and tumorigenesis of the collected CTCs were confirmed by re-implanting the cells into a non-cancer-bearing mouse. Ultrasonography with Doppler showed a significant correlation between CTCs and tumor vascular density (p-value < 0.01), rather than tumor volume (p-value 0.076). Abstract Background: This study used NeuN transgenic (NTTg) mice with spontaneous breast tumor development to evaluate the dynamic changes of circulating tumor cells (CTCs) prior to and during tumor development. Methods: In this longitudinal, clinically uninterrupted study, we collected 75 μL of peripheral blood at the age of 8, 12, 16, and 20 weeks in the first group of five mice, and at the age of 32 weeks, the time of tumor palpability, and one week after tumor palpability in the second group of four mice. Diluted blood samples were run through a modified mouse-CMx chip to isolate the CTCs. Results: The CTC counts of the first group of mice were low (1 ± 1.6) initially. The average CTC counts were 16 ± 9.5, 29.0 ± 18.2, and 70.0 ± 30.3 cells per 75 μL blood at the age of 32 weeks, the time of tumor palpability, and one week after tumor palpability, respectively. There was a significant positive correlation between an increase in CTC levels and tumor vascular density (p-value < 0.01). This correlation was stronger than that between CTC levels and tumor size (p-value = 0.076). The captured CTCs were implanted into a non-tumor-bearing NTTg mouse for xenografting, confirming their viability and tumorigenesis. Conclusion: Serial CTCs during an early stage of tumor progression were quantified and found to be positively correlated with the later tumor vascular density and size. Furthermore, the successful generation of CTC-derived xenografts indicates the tumorigenicity of this early onset CTC population.

Abstract
BRCA1, BRCA2, TP53 and ATM gene mutations are the most studied tumour suppressor genes (TSGs) influencing the loco-regional approach to breast cancer (BC). Due to altered radio sensitivity of mutated cancer cells, mastectomy has always been advised in most patients with BC linked to TSGs mutations in order to avoid or minimize the use of adjuvant radiotherapy (ART). Whether ART is safe or not in these carriers is still debated. As a result, this issue has been widely discussed in the recent ASTRO and ASCO papers, yielding important and useful recommendations on the use of ART according to the mutational status. In this review, we have highlighted the impact of these mutations on local control, toxicities, second tumors, and contralateral breast cancers (CBCs) after ART to solve remaining doubts and encourage the safe use of ART when indicated.

Abstract
Simple Summary In this survey study, we examined survey responses from 397 women with stage 0 to III unilateral breast cancer and found that partners, physicians, and the media were significant relative to the patient’s own influence in their decision to undergo a CPM. The findings of this study may inform policy by highlighting the need for educational aids, programs, or tools that help women with unilateral breast cancer make informed, evidence-based decisions regarding CPM efficacy. Abstract (1) Background: The relatively high rate of contralateral prophylactic mastectomy (CPM) among women with early stage unilateral breast cancer (BC) has raised concerns. We sought to assess the influence of partners, physicians, and the media on the decision of women with unilateral BC to undergo CPM and identify clinicopathological variables associated with the decision to undergo CPM. (2) Patients and Methods: Women with stage 0 to III unilateral BC who underwent CPM between January 2010 and December 2017. Patients were surveyed regarding factors influencing their self-determined decision to undergo CPM. Partner, physician, and media influence factors were modeled by logistic regressions with adjustments for a family history of breast cancer and pathological stage. (3) Results: 397 (29.6%) patients completed the survey and were included in the study. Partners, physicians, and the media significantly influenced patients’ decision to undergo CPM. The logistic regression models showed that, compared to self-determination alone, overall influence on the CPM decision was significantly higher for physicians (p = 0.0006) and significantly lower for partners and the media (p < 0.0001 for both). Fifty-nine percent of patients’ decisions were influenced by physicians, 28% were influenced by partners, and only 17% were influenced by the media. The model also showed that patients with a family history of BC had significantly higher odds of being influenced by a partner than did those without a family history of BC (p = 0.015). (4) Conclusions: Compared to self-determination, physicians had a greater influence and partners and the media had a lower influence on the decision of women with unilateral BC to undergo CPM. Strong family history was significantly associated with a patient’s decision to undergo CPM.

Abstract
The most common breast cancer (BC) susceptibility genes beyond BRCA1/2 are ATM and CHEK2. For the purpose of exploring the clinicopathologic characteristics of BC developed by ATM or CHEK2 mutation carriers, we reviewed the archive of our Family Cancer Clinic. Since 2018, 1185 multi-gene panel tests have been performed. Nineteen ATM and 17 CHEK2 mutation carriers affected by 46 different BCs were identified. A high rate of bilateral tumors was observed in ATM (26.3%) and CHEK2 mutation carriers (41.2%). While 64.3% of CHEK2 tumors were luminal A-like, 56.2% of ATM tumors were luminal B-like/HER2-negative. Moreover, 21.4% of CHEK2-related invasive tumors showed a lobular histotype. About a quarter of all ATM-related BCs and a third of CHEK2 BCs were in situ carcinomas and more than half of ATM and CHEK2-related BCs were diagnosed at stage I-II. Finally, 63.2% of ATM mutation carriers and 64.7% of CHEK2 mutation carriers presented a positive BC family history. The biological and clinical characteristics of ATM and CHEK2-related tumors may help improve diagnosis, prognostication and targeted therapeutic approaches. Contralateral mastectomy should be considered and discussed with ATM and CHEK2 mutation carriers at the first diagnosis of BC.

Abstract
Germ-line mutation in BRCA (BReast CAncer gene) 1 or BRCA2 are found in 3–4% of all women with breast cancer. These patients have a significant increased risk of breast and ovarian cancer. They are often younger when diagnosed with the mutation, and the possible breast cancer they get is often aggressive with inferior outcome. There are risk reducing strategies, and the most powerful strategy is risk reducing surgery, both risk reducing bilateral mastectomy (RRM) and risk reducing bilateral salpino-oophorectomy (PBSO). This review is meant to address breast surgery in patients with germline BRCA mutation. The guidelines and techniques applied is under continuous change and it is important for the clinicians to be well informed to provide the patient with the information needed for them to make an informed decision on what risk strategy to choose. Patients with germ-line mutation in BRCA1 or BRCA2 have a significant increased risk of breast and ovarian cancer. There are different risk reducing strategies and the most powerful strategy is risk-reducing surgery, both risk reducing bilateral mastectomy and risk reducing bilateral salpingo-oophorectomy. Guidelines and techniques for the risk reducing surgery of the breast are under continuous change and improvement. Breast conserving therapy is not associated with worse survival and is a good option for a BRCA mutation carrier diagnosed with breast cancer. Risk-reducing mastectomy can be performed in a later setting. The management of BRCA mutation carriers, both affected and unaffected, should be performed in a multidisciplinary team. Physicians need to be systematically educated and updated on the most recent literature.

Abstract
BACKGROUND Carriers of deleterious mutations in breast cancer predisposition genes are presented with critical choices regarding cancer risk management. Risk-reduction mastectomy is a major preventative strategy in this population. Understanding the decision-making process for prophylactic mastectomy is essential in patient-centered care for high-risk carriers and patients with breast cancer. We sought to provide insight into influential factors underlying preventative surgery decisions among individuals with high breast cancer risk. MATERIALS AND METHODS We conducted a retrospective chart review of pathogenic carriers of high-risk breast cancer genes who presented to the Moffitt GeneHome clinic between March 2017 and June 2020. Associations between preventative mastectomy choice and influence variables were analyzed via unadjusted and adjusted logistic regression models. RESULTS Of 258 high-risk mutation carriers, 104 (40.3%) underwent risk-reduction mastectomy. A significantly higher proportion of mastectomy patients reported prior history of breast cancer (68.9% vs. 16.5%; P < .001) and history of other risk-reduction or noncancer-related surgeries (61.7% vs. 25.8%; P < .001). Significant predictors affecting surgery decision included previous breast cancer history (adjusted odds ratio [aOR], 10.48; 95% confidence interval [CI], 5.59-19.63; P < .0001), other risk-reduction or noncancer-related surgical history (aOR, 4.65; 95% CI, 2.28-9.47; P < .0001), and age at presentation to the genetics clinic (< 35 years old: aOR, 2.77; 95% CI, 1.04-7.4; P = .042; 35-55 years old: aOR, 2.48; 95% CI, 1.19-5.18; P = .016). CONCLUSIONS Preventive mastectomy decisions are highly personal and complex. In our sample, we observed prior history or concurrent breast cancer, history of other risk-reduction surgery or noncancer-related surgery, and younger age at presentation to the GeneHome clinic to be predictive of mastectomy uptake.

[PMID: 33030641 DOI: 10.1245/s10434-020-09178-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 09/07/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Currently, data on pathogenic variants in the CHEK2 gene and their impact on cancer risk are lacking. This study aimed to explore the characteristics of breast cancer (BC) patients from families with CHEK2 pathogenic variants in Slovenia. METHODS In the years 2014 to 2019, CHEK2 pathogenic variants/likely pathogenic variants (PV/LPVs) were found in probands from 50 different families who underwent genetic counseling and testing using a multigene panel at the authors' institution. Altogether, the study enrolled 75 individuals from 50 CHEK2 families who were carriers of a CHEK2 PV/LPV. The clinical data on 41 BC patients with CHEK2 PV/LPV and other carriers of CHEK2 PV/LPV from Slovenia were collected and analyzed. RESULTS Breast cancer was diagnosed in 41 of 75 CHEK2 PV/LPV carriers (40 females, 1 male). The mean age at BC diagnosis was 42.8 years (range, 21-63 years), and 27 (65.8%) of the 41 of patients with BC had a positive family history for BC. Contralateral BC (CBC) was observed in 8 (19.5%) of the 41 patients (mean age, 55.6 years). Of 12 patients with human epidermal growth factor receptor 2 (HER2)-positive tumor type, a c.444+1G > A PV/LPV was detected in 4 patients, c.349A > G in 3 patients, deletion of exons 9-10 in 3 patients, deletion of exon 8 in 1 patient, and c.1427C > T PV/LPV in 1 patient. CONCLUSION Bilateral BC was diagnosed in as many as 19.5% of the Slovenian BC patients with CHEK2 PV/LPVs. Breast cancer associated with a germline CHEK2 PV/LPV occurs in younger patients compared with sporadic BC.

[PMID: 32720048 DOI: 10.1245/s10434-020-08889-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 06/15/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND An increasing number of breast cancer patients are undergoing expanded genetic testing and are being identified as germline mutation carriers. We sought to determine rates of contralateral risk-reducing mastectomy (CRRM) in patients with various germline mutations. PATIENTS AND METHODS All women ≥ 18 years of age with unilateral breast cancer who underwent multigene panel testing between January 1, 2014 and August 1, 2019 at our academic institution were identified. Demographic, tumor, and treatment variables were identified from the medical record. Multivariable analyses were performed to compare factors associated with performance of CRRM. RESULTS We identified 1613 patients, of whom 28.1% had a pathogenic variant and 40.1% had variants of uncertain significance (VUS). Overall, 420 patients (26.0%) underwent a CRRM. On multivariable analysis, factors associated with CRRM included age < 50 years (OR 3.8, 95% CI 3.0, 5.0), race (OR 0.5, 95% CI 0.3, 0.7 and OR 0.4, 95% CI 0.2, 0.7 for Black and Asian women, respectively, versus White women), and the presence of any germline mutation or VUS (OR 13.2, 95% CI 8.7, 20.2 for BRCA1/2; OR 3.9, 95% CI 2.7, 5.8 for non-BRCA germline mutation; and OR 1.8, 95% CI 1.3, 2.6 for VUS). CONCLUSIONS In breast cancer patients who undergo multigene panel testing, a sizeable number of women with pathogenic non-BRCA germline findings are opting for CRRM. Given that the risk of contralateral breast cancer in women with most pathogenic mutations other than BRCA1/2 remains poorly characterized, these data have implications for risk counseling and for ascertaining the true risks of contralateral breast cancer in this population.
