Abstract
Given the rarity of RAD51C mutations, the risk and treatment of metachronous breast cancer after the diagnosis of ovarian cancer in RAD51C mutation carriers is not clear, especially for those who have received PARPi treatment. We report the case of a 65-year-old woman diagnosed with stage IIIC high-grade serous primary fallopian tube cancer. The patient had no family history of breast or ovarian cancer. The patient received three cycles of neoadjuvant chemotherapy with paclitaxel and carboplatin and achieved a complete response. After interval debulking surgery, the patient received three cycles of adjuvant chemotherapy. Collection and extraction of saliva DNA for next-generation sequencing identified a RAD51C mutation c.838-2 A > G. The patient received niraparib as front-line maintenance treatment. After 36 months of niraparib treatment, the patient had grade II invasive ductal carcinoma of the left breast that was positive for estrogen receptor (90%) and Ki-67 (30%) and negative for progesterone receptor and human epidermal growth factor receptor 2. Computed tomography revealed the absence of distant metastases. Modified radical mastectomy and axillary lymph node dissection were then performed. The final pathological report of the breast showed a 1.8 cm Bloom-Richardson grade II invasive ductal carcinoma in the left breast with axillary lymph node metastasis (1/21). Finally, the breast cancer was stage IIA, pT1cN1M0. The metachronous breast cancer in this case may be the first report of second primary cancer in fallopian tube cancer patient harboring a RAD51C mutation during niraparib treatment. Further studies are required to determine optimal treatment.

Cost-Effectiveness of Risk-Reducing Surgery for Breast and Ovarian Cancer Prevention: A Systematic Review. Cancers (Basel) 2022; 14:cancers14246117. [PMID: 36551605 PMCID: PMC9776851 DOI: 10.3390/cancers14246117] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 12/04/2022] [Accepted: 12/09/2022] [Indexed: 12/14/2022] Open
Abstract
Policymakers require robust cost-effectiveness evidence of risk-reducing-surgery (RRS) for decision making on resource allocation for breast cancer (BC)/ovarian cancer (OC)/endometrial cancer (EC) prevention. We aimed to summarise published data on the cost-effectiveness of risk-reducing mastectomy (RRM)/risk-reducing salpingo-oophorectomy (RRSO)/risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) for BC/OC prevention in intermediate/high-risk populations; hysterectomy and bilateral salpingo-oophorectomy (BSO) in Lynch syndrome women; and opportunistic bilateral salpingectomy (OBS) for OC prevention in baseline-risk populations. Major databases were searched until December 2021 following a prospective protocol (PROSPERO-CRD42022338008). Data were qualitatively synthesised following a PICO framework. Twenty two studies were included, with a reporting quality varying from 53.6% to 82.1% of the items scored in the CHEERS checklist. The incremental cost-effectiveness ratio/incremental cost-utility ratio and cost thresholds were inflated and converted to US$2020, using the original currency consumer price index (CPI) and purchasing power parities (PPP), for comparison. Eight studies concluded that RRM and/or RRSO were cost-effective compared to surveillance/no surgery for BRCA1/2, while RRESDO was cost-effective compared to RRSO in one study. Three studies found that hysterectomy with BSO was cost-effective compared to surveillance in Lynch syndrome women. Two studies showed that RRSO was also cost-effective at ≥4%/≥5% lifetime OC risk for pre-/post-menopausal women, respectively. Seven studies demonstrated the cost-effectiveness of OBS at hysterectomy (n = 4), laparoscopic sterilisation (n = 4) or caesarean section (n = 2). This systematic review confirms that RRS is cost-effective, while the results are context-specific, given the diversity in the target populations, health systems and model assumptions, and sensitive to the disutility, age and uptake rates associated with RRS. Additionally, RRESDO/OBS were sensitive to the uncertainty concerning the effect sizes in terms of the OC-risk reduction and long-term health impact. Our findings are relevant for policymakers/service providers and the design of future research studies.

Uptake Rates of Risk-Reducing Surgeries for Women at Increased Risk of Hereditary Breast and Ovarian Cancer Applied to Cost-Effectiveness Analyses: A Scoping Systematic Review.

Abstract
The cost-effectiveness of genetic screen-and-treat strategies for women at increased risk for breast and ovarian cancer often depends on the women's willingness to make use of risk-reducing mastectomy (RRM) or salpingo-oophorectomy (RRSO). To explore the uptake rates of RRM and RRSO applied in health economic modeling studies and the impact of uptake rates on the incremental cost-effectiveness ratios (ICER), we conducted a scoping literature review. In addition, using our own model, we conducted a value of information (VOI) analysis. Among the 19 models included in the review, the uptake rates of RRM ranged from 6% to 47% (RRSO: 10% to 88%). Fifty-seven percent of the models applied retrospective data obtained from registries, hospital records, or questionnaires. According to the models' deterministic sensitivity analyses, there is a clear trend that a lower uptake rate increased the ICER and vice versa. Our VOI analysis showed high decision uncertainty associated with the uptake rates. In the future, uptake rates should be given more attention in the conceptualization of health economic modeling studies. Prospective studies are recommended to reflect regional and national variations in women's preferences for preventive surgery.

Abstract
OBJECTIVES BRCA 1 or 2 mutation carriers have increased risk of developing breast cancer (BC) and serous epithelial ovarian cancer (EOC). The incidence of BC over time after EOC is unknown. Optimal BC surveillance for BRCA mutation carriers following EOC has not been defined. METHODS A multi-institutional retrospective chart review was performed. Patients with BRCA -associated EOC diagnosed between 1996 and 2016 were followed for an average of 80 months. Women with previous bilateral mastectomy were excluded; women with prior BC and an intact breast were included. Descriptive statistics, Chi Square, and univariate survival analysis were performed. RESULTS 184 patients with BRCA -associated EOC were identified. Eighteen (10%) were diagnosed with BC a median of 48 months following EOC. Two (1%) with prior BC developed contralateral BC and 16 (9%) developed primary BC. The majority of BC (55%) was diagnosed 3 years following EOC. The 3-, 5- and 10-year incidence of BC was 5.6%, 9.5% and 33.3%. Annual mammography was performed in 43% and MRI in 34%. Twenty-eight (15%) women underwent risk-reducing mastectomy (RRM). There was no statistically significant difference in BC screening between women with, and without, a prior BC. BC was most commonly detected on mammogram. Three (17%) women had occult BC at the time of RRM. Nine (50%) had DCIS, and 8 (44%) had stage I/II BC. Median 5- and 10-year survival was 68% and 43% and was comparable between groups. CONCLUSIONS Ten percent of women developed BC after EOC. The incidence of BC following EOC in BRCA carriers increases over time, and surveillance is recommended given their enhanced survival of EOC. Timely genetic testing for women with EOC is imperative to better triage BC screening resources and treatment.

Abstract
Breast cancer (BC) is the second most common cancer in women, affecting 1 in 8 women in the United States (12.5%) in their lifetime. However, some women have a higher lifetime risk of BC because of genetic and lifestyle factors, mammographic breast density, and reproductive and hormonal factors. Because BC risk is variable, screening and prevention strategies should be individualized after considering patient-specific risk factors. Thus, health care professionals need to be able to assess risk profiles, identify high-risk women, and individualize screening and prevention strategies through a shared decision-making process. In this article, we review the risk factors for BC, risk-assessment models that identify high-risk patients, and preventive medications and lifestyle modifications that may decrease risk. We also discuss the benefits and limitations of various supplemental screening methods.

Abstract
The identification that breast cancer is hereditary was first described in the nineteenth century. With the identification of the BRCA1 and BRCA 2 breast/ovarian cancer susceptibility genes in the mid-1990s and the introduction of genetic testing, significant advancements have been made in tailoring surveillance, guiding decisions on medical or surgical risk reduction and cancer treatments for genetic variant carriers. This review discusses various medical and surgical management options for hereditary breast cancers.

Abstract
In this paper, a cost decision-making model that compares the healthcare costs for diverse treatment strategies is built for BRCA-mutated women with breast cancer. Moreover, this model calculates the cancer treatment costs that could potentially be prevented, if the treatment strategy with the lowest total cost, along the entire lifetime of the patient, is chosen for high-risk women with breast cancer. The benchmark of the healthcare costs for diverse treatment strategies is selected in the presence of uncertainty, i.e., considering, throughout the lifetime of the patient, the risks and complications that may arise in each strategy and, therefore, the costs associated with the management of such events. Our results reveal a clear economic advantage of adopting the cost decision-making model for benchmarking the healthcare costs for various treatment strategies for BRCA-mutated women with breast cancer. The cost savings were higher when all breast cancer patients underwent counseling and genetic testing before deciding on any diagnostic-therapeutic path, with a probability of obtaining savings of over 75%.

Abstract
Hereditary Diffuse Gastric Cancer (HDGC) is a complex inherited syndrome caused by CDH1 germline mutations. DGC is the hallmark cancer of this genetic predisposition, but several other cancers are associated with these CDH1 mutations. In this review, we revised all studies reporting CDH1 mutations in non-GC patients. The selected studies included: (a) families aggregating with GC and other cancers, both, and (b) families presenting only non-gastric tumors association. Among non-gastric tumors, our results show that CDH1 mutations are most frequently identified in breast cancer. The frequency of missense mutations is higher in the non-GC group, as the age at diagnosis in this group. Moreover, the predominant CDH1 mutation affects the extracellular domain. Our data suggest that CDH1 genetic testing should be considered also in other cancers, especially breast tumors.

Abstract
BACKGROUND Surgical options for breast cancer are numerous and span multiple surgical disciplines. Decision analyses aid surgeons in making the most cost-effective choice, thus reducing health care expenditure while maximizing patient outcome. In this study, we aimed to evaluate existing breast surgery cost-effectiveness literature against the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) validated scoring system. METHODS A PRISMA search was performed for cost-effectiveness within breast surgery. Articles were scored with CHEERS criteria on a 0-24 scale and qualitative data were collected. Subgroup analysis was performed comparing pre-CHEERS (published in 2013 or earlier) and post-CHEERS (published in 2014 or later) cohorts. Chi-squared analysis was performed to compare where studies lost points between cohorts. RESULTS Of 2279 articles screened, 46 articles were included. The average CHEERS score was 18.18. Points were most often lost for characterizing heterogeneity, followed by discount rate, incremental costs and outcomes, and abstract. Quality-adjusted life year was the most commonly used health outcome, with visual model or analog scales as the most commonly used measure of effectiveness obtained primarily from surgeons or physicians. Most articles characterized uncertainty by deterministic sensitivity analysis, followed by both deterministic and probabilistic, then probabilistic. Average CHEERS scores were similar between pre- and post-CHEERS cohorts (17.67 vs. 18.40, P > .05) There were several significant differences in where articles lost points between pre- and post-CHEERS cohorts. DISCUSSION In order to standardize the reporting of results, cost-effectiveness studies in breast surgery should adhere to the current CHEERS criteria and aim to better characterize heterogeneity in their analyses.

Abstract
BRCA1 or 2 mutations result in higher cancer risk for breast cancer (BC) and epithelial ovarian cancer (EOC) for carriers than exists in the general population. Optimal breast imaging surveillance in these patients has not been well defined. An Institutional Review Board-approved, multi-institutional retrospective chart review was performed. Patients diagnosed with BRCA-associated EOC between 1990-2015 were identified; demographic and clinical data were collected and analyzed. 192 BRCA mutation–positive patients with EOC were identified. 16/192 (8.3%) women were diagnosed with BC following EOC, at a median of 50 (range 5-327) months following EOC diagnosis and median age 59.5 (45-84) years. Breast cancer was most commonly detected on mammogram 7/16 (44%) or clinical exam 7/16 (44%). 2/16 (12.5%) had occult BC found during risk-reducing mastectomy. 14 (88%) had early-stage (0-2) disease. At mean follow-up of 8.1 years, 6 (37.5%) patients with BC following EOC had died due to EOC. The risk of BC diagnosis following EOC in BRCA mutation carriers is low; most of these BCs are early stage and diagnosed with mammography or physical exam. Overall, survival in BRCA mutation carriers is dominated by EOC-related mortality. Breast cancer surveillance in BRCA mutation carriers following EOC should prioritize nonsurgical strategies.

Abstract
OBJECTIVES Current risk-reducing salpingo-oophorectomy (RRSO) guidelines for individuals with BRCA1/2 mutations do not account for risk variability due to BRCA1/2 cluster region mutations that are associated with varying risks for the development of breast and ovarian cancer. We assessed whether current recommendations are appropriate for individual patients considering mutation-specific risks. METHODS Using a hypothetical cohort of patients with BRCA1/2 mutations, we constructed Markov models allowing for the estimation of mean life expectancy based upon BRCA1/2 mutation, the presence of a cluster region mutation (Ovarian Cancer Cluster Region (OCCR), Breast Cancer Cluster Region (BCCR), or non-BCCR/OCCR), age at time of BRCA1/2 diagnosis (20-65), and age at time of RRSO (21-80). RESULTS For all BRCA1/2 mutation types, the optimal strategy was to undergo RRSO as early as possible. For BRCA1/2 carriers who delayed RRSO or who were identified with a mutation later in life, the OCCR mutation tended to be associated with lower life expectancy estimates than the BCCR and non-BCCR/OCCR mutations. Minimal delays in RRSO (i.e., neighboring 5-year intervals) were associated with minor losses in life expectancy. Variables associated with greatest impact on life expectancy included ovarian cancer risk after RRSO, breast cancer mortality rate, non-cancer mortality associated with RRSO, and breast cancer stage distribution. CONCLUSIONS BRCA1/2 cluster regions may provide more precise estimates of life expectancy in counselling and shared decision-making. The most appropriate timing for RRSO is a complex decision and must be individualized for each patient.

Abstract
In an increasingly data-driven age of medicine, do companies that offer genetic testing directly to patients represent an important part of personalising care, or a dangerous threat to privacy? Should we celebrate this new mechanism of patient involvement, or fear its implications?The Universities of Oxford and Cambridge addressed these issues in the 10th annual Medical Ethics Varsity Debate, through the motion: "This House Regrets the Rise of Direct-to-Consumer Genetic Testing". This article summarises and extends key arguments made in the debate, exploring the impacts of such genetic testing on both the individual patient and broader society, with special consideration as to whether companies can ever truly guarantee anonymity of genetic data.

Different Patterns of Risk Reducing Decisions in Affected or Unaffected BRCA Pathogenic Variant Carriers. Cancer Res Treat 2018; 51:280-288. [PMID: 29747489 PMCID: PMC6333981 DOI: 10.4143/crt.2018.079] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 05/02/2018] [Indexed: 12/14/2022] Open
Abstract
Purpose The purpose of this study was to investigate decision patterns to reduce the risks of BRCArelated breast and gynecologic cancers in carriers of BRCA pathogenic variants. We found a change in risk-reducing (RR) management patterns after December 2012, when the National Health Insurance System (NHIS) of Korea began to pay for BRCA testing and riskreducing salpingo-oophorectomy (RRSO) in pathogenic-variant carriers. Materials and Methods The study group consisted of 992 patients, including 705 with breast cancer (BC), 23 with ovarian cancer (OC), 10 with both, and 254 relatives of high-risk patients who underwent BRCA testing at the National Cancer Center of Korea from January 2008 to December 2016.We analyzed patterns of and factors in RR management. Results Of the 992 patients, 220 (22.2%) were carriers of BRCA pathogenic variants. About 92.3% (203/220) had a family history of BC and/or OC,which significantly differed between BRCA1 and BRCA2 carriers (p < 0.001). All 41 male carriers chose surveillance. Of the 179 female carriers, 59 of the 83 carriers (71.1%) with BC and the 39 of 79 unaffected carriers (49.4%) underwent RR management. None of the carriers affected with OC underwent RR management. Of the management types, RRSO had the highest rate (42.5%) of patient choice. The rate of RR surgery was significantly higher after 2013 than before 2013 (46.3% [74/160] vs. 31.6% [6/19], p < 0.001). Conclusion RRSO was the preferred management for carriers of BRCA pathogenic variants. The most important factors in treatment choice were NHIS reimbursement and/or the severity of illness.

Genet Med 2018; 20:1145-1156. [PMID: 29323669 DOI: 10.1038/gim.2017.255] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Accepted: 12/05/2017] [Indexed: 02/01/2023] Open
Abstract
PURPOSE To review the evidence for the effectiveness and cost-effectiveness of cancer risk management interventions for BRCA carriers. METHODS Comparative effectiveness and cost-effectiveness analyses were identified by searching scientific and health economic databases. Eligible studies modeled the impact of a cancer risk management intervention in BRCA carriers on life expectancy (LE), cancer incidence, or quality-adjusted life years (QALYs), with or without costs. RESULTS Twenty-six economic evaluations and eight comparative effectiveness analyses were included. Combined risk-reducing salpingo-oophorectomy and prophylactic mastectomy resulted in the greatest LE and was cost-effective in most analyses. Despite leading to increased LE and QALYs, combined mammography and breast magnetic resonance imaging (MRI) was less likely to be cost-effective than either mammography or MRI alone, particularly for women over 50 and BRCA2 carriers. Variation in patient compliance to risk management interventions was incorporated in 11/34 studies with the remaining analyses assuming 100% adherence. CONCLUSION Prophylactic surgery and intensive breast screening are effective and cost-effective in models of BRCA carrier risk management. Findings were based predominantly on assuming perfect adherence to recommendations without assessment of the health-care resource use and costs related to engaging patients and maximizing compliance, meaning the real-world impact on clinical outcomes and resource use remains unclear.
