Oliveira D, Fernandes S, Miguel I, Fragoso S, Vaz F. Is There a Role for Risk-Reducing Bilateral Breast Surgery in BRCA1/2 Ovarian Cancer Survivors? An Observational Study. Curr Oncol 2023; 30:7810-7817. [PMID: 37754482 PMCID: PMC10528403 DOI: 10.3390/curroncol30090567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 08/16/2023] [Accepted: 08/21/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Risk-reducing surgeries are an option for cancer risk management in BRCA1/2 individuals. However, while adnexectomy is commonly recommended in breast cancer (BC) survivors, risk-reducing bilateral breast surgery (RRBBS) is controversial in ovarian cancer (OC) survivors due to relapse rates and mortality. METHODS We conducted a retrospective analysis of BRCA1/2-OC survivors, with OC as first cancer diagnosis. RESULTS Median age at OC diagnosis for the 69 BRCA1/2-OC survivors was 54 years. Median overall survival was 8 years, being significantly higher for BRCA2 patients than for BRCA1 patients (p = 0.011). Nine patients (13.2%) developed BC at a median age of 61 years. The mean overall BC-free survival was 15.5 years (median not reached). Eight patients (11.8%) underwent bilateral mastectomy (5 simultaneous with BC treatment; 3 RRBBS) at a median age of 56.5 years. The median time from OC to bilateral mastectomy/RRBBS was 5.5 years. CONCLUSIONS This study adds evidence regarding a lower BC risk after BRCA1/2-OC and higher survival for BRCA2-OC patients. A comprehensive analysis of the competing risks of OC mortality and recurrence against the risk of BC should be individually addressed. Surgical BC risk management may be considered for longer BRCA1/2-OC disease-free survivors. Ultimately, these decisions should always be tailored to patients' characteristics and preferences.

Disparities between Uptake of Germline BRCA1/ 2 Gene Tests and Implementation of Post-test Management Strategies in Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Patients. J Korean Med Sci 2021; 36:e241. [PMID: 34609091 PMCID: PMC8490789 DOI: 10.3346/jkms.2021.36.e241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 08/08/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND To assess the rate of germline BRCA gene tests in epithelial ovarian cancer (EOC) patients and uptake of post-test risk management strategies in BRCA1/2-mutated patients. METHODS Institutional databases were searched to identify patients who were diagnosed with epithelial ovarian, fallopian tube, or primary peritoneal cancer (EOC) between 2009 and 2019 in two academic hospitals. Retrospective review on medical records was performed to collect clinico-pathologic variables, including performance of germline BRCA gene test and its results, as well as conduct of breast cancer screening tests and cascade testing. If annual mammography +/- breast ultrasonography was performed, it was considered that regular breast cancer surveillance was done. RESULTS A total of 840 women with EOC were identified during the study period. Of these, 454 patients (54.0%) received BRCA gene testing and 106 patients (106/454, 23.3%) were positive for BRCA1/2 mutations. The rate of BRCA tests has markedly increased from 25.8% in 2009-2012 to 62.7% in 2017-2019. Among the 93 patients with BRCA1/2 mutation without previous personal breast cancer history, 20 patients (21.5%) received annual mammography with or without breast ultrasonography for regular surveillance. Among the 106 BRCA1/2-mutated EOC patients, cascade testing on family members was performed only in 13 patients (12.3%). CONCLUSION Although BRCA1/2 gene tests have been substantially expanded, the uptake of post-test risk management strategies, including breast cancer screening for BRCA1/2-mutated patients and cascade testing for family members, has remained low. Strategies to increase its uptake and education about the importance of post-test risk managements are needed.

Breast cancer incidence in BRCA mutation carriers with ovarian cancer: A longitudal observational study. Gynecol Oncol 2021; 162:715-719. [PMID: 34172288 DOI: 10.1016/j.ygyno.2021.06.009] [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: 03/22/2021] [Accepted: 06/10/2021] [Indexed: 12/24/2022]
Abstract
OBJECTIVES We evaluated the incidence of breast cancer and overall survival in a multi-center cohort of ovarian cancer patients carrying BRCA1/2 mutations in order to assess risks and formulate optimal preventive interventions and/or surveillance. METHODS Medical records of 502 BRCA1/2 mutation carriers diagnosed with ovarian cancer between 2000 and 2018 at 7 medical centers in Israel and one in New York were retrospectively analyzed for breast cancer diagnosis. Data included demographics, type of BRCA mutations, surveillance methods, timing of breast cancer diagnosis, and family history of cancer. RESULTS The median age at diagnosis of ovarian cancer was 55.8 years (range, 23.9-90.1). A third (31.5%) had a family history of breast cancer and 17.1% of ovarian cancer. Most patients (67.3%) were Ashkenazi Jews, 72.9% were BRCA1 carriers. Breast cancer preceded ovarian cancer in 17.5% and was diagnosed after ovarian cancer in 6.2%; an additional 2.2% had a synchronous presentation. Median time to breast cancer diagnosis after ovarian cancer was 46.0 months (range, 11-168). Of those diagnosed with both breast cancer and ovarian cancer (n = 31), 83.9% and 16.1% harbored BRCA1 and BRCA2 mutations, respectively. No deaths from breast cancer were recorded. Overall survival did not differ statistically between patients with an ovarian cancer diagnosis only and those diagnosed with breast cancer after ovarian cancer. CONCLUSION The low incidence of breast cancer after ovarian cancer in women carrying BRCA1/2 mutations suggests that routine breast surveillance, rather than risk-reducing surgical interventions, may be sufficient in ovarian cancer survivors.
