Contralateral breast cancer (CBC) is the development of a second new breast cancer in the other breast. Women who have either the BRCA1 or BRCA2 mutations have an especially increased risk of developing CBC. Women with a mutation in BRCA1 or BRCA2 face a lifetime risk of breast cancer of ∼80%, and following the first diagnosis the10‐year risk of contralateral breast cancer is ∼30%. For women who had their first breast cancer before the age of 40 years, the cumulative risk of contralateral breast cancer after 25 years was 55.1% for BRCA1, 38.4% for BRCA2, and 28.4% for 245 were diagnosed with breast cancer in the opposite breast (contralateral breast cancer) Using statistical analysis, the researchers found: Up to age 80, breast cancer risk was 72% for women with a BRCA1 mutation and 69% for women with a BRCA2 mutation. Prophylactic contralateral (CLT) breast radiotherapy was associated with significantly fewer and delayed cases of breast cancer in women having standard therapy for their ipsilateral BRCA mutation-associated breast cancers in a study from Israel reported in a poster session at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting . “Among our 41 BRCA mutation carriers, there were seven cases of contralateral breast cancer (17%), while in the mutation noncarriers, 36 patients (8%) experienced contralateral breast cancer.” Multivariate analyses indicated that BRCA status and aromatase inhibitor use were significantly associated with contralateral breast cancer. It is well-known that BRCA mutation carriers are at higher risk of contralateral breast cancer (CBC) than non-carriers, ; BRCA mutations have been therefore regarded as responsible for this excess risk,.

Methods: A total of 128 breast cancer patients with germline BRCA mutations and 4,754 control breast cancer patients were enrolled. 2005-07-04 · The median follow-up time was 69 months (range, 10–280 months). In the 86 BRCA-WT patients, the first event was a local relapse in 3 (3%), metachronous contralateral breast cancer in 7 (8% of the 84 patients with primary unilateral breast cancer) and distant metastases in16 (19%). A contralateral prophylactic mastectomy (CPM) is a risk-reducing mastectomy performed in the clinical setting for the patient diagnosed with an invasive or a noninvasive breast cancer.

BRCA1/2 mutation carriers are at a higher risk of breast cancer and of subsequent contralateral breast cancer (CBC). This study aims to evaluate the evidence of the effect of the BRCA1/2-carriership on CBC cumulative risk in female breast cancer patients. Following a diagnosis of breast cancer, BRCA mutation carriers face an increased risk of developing a second (contralateral) cancer in the unaffected breast. It is important to identify predictors of contralateral cancer in order to make informed decisions about bilateral mastectomy.

Broadly the risk of contralateral breast cancer (CBC) is: • BRCA 1 or 2 gene carrier: 2 - 3% per annum (20-30% at 10yrs)(6). • Woman with no significant FH:.

Aromase inhibitors may reduce the rate of contralateral breast cancer in women who already have the disease and are positive for BRCA mutations. For the 2,213 women eligible for the contralateral breast cancer risk analysis, the cumulative risk of a contralateral breast cancer 20 years after a first breast cancer was 40% for BRCA1 mutation carriers and 26% for BRCA2 mutation carriers.

2019-12-17 · Background Breast cancer survivors are at risk for contralateral breast cancer (CBC), with the consequent burden of further treatment and potentially less favorable prognosis. We aimed to develop and validate a CBC risk prediction model and evaluate its applicability for clinical decision-making.

Contralateral breast cancer risk depends on age at ﬁrst breast cancer and on the affected BRCA gene, and this risk should be considered in treatment planning. J Clin Oncol 27:5887-5892. © 2009

2011-04-12 Tamoxifen and contralateral breast cancer in BRCA1 and BRCA2 carriers: an update. / Gronwald, J; Tung, N; Foulkes, WD; Offit, K; Gershoni, R; Daly, M; Kim-Sing, C Purpose Breast cancer is increasing around the globe, including Asia. We aimed to examine the survival and risk of contralateral breast cancer (CBC) in Asian breast cancer patients with BRCA mutations. Methods: A total of 128 breast cancer patients with germline BRCA mutations and 4,754 control breast cancer patients were enrolled. BRCA 1/2 mutation carriers were more than twice as likely to develop contralateral breast cancer as noncarriers. Compared to patients who did not receive aromatase inhibitors, those who received them had smaller hazard of developing contralateral breast cancer (hazard ratio = 0.42). The risk of a contralateral breast cancer, the decision-making process to undergo a CPM, and outcomes will be reviewed in this topic.
