PURPOSE The risks, benefits, and utilities of multiplex panels for breast cancer susceptibility are unknown, and new counseling and informed consent models are needed. We sought to obtain patient feedback and early outcome data with a novel tiered-binned model for multiplex testing. METHODS BRCA1/2-negative and untested patients completed pre- and(More)
PURPOSE Multiplex genetic testing, including both moderate- and high-penetrance genes for cancer susceptibility, is associated with greater uncertainty than traditional testing, presenting challenges to informed consent and genetic counseling. We sought to develop a new model for informed consent and genetic counseling for four ongoing studies. METHODS(More)
UNLABELLED BRCA1 and BRCA2 are the most important breast and ovarian cancer susceptibility genes. Biallelic mutations in BRCA2 can lead to Fanconi anemia and predisposition to cancers, whereas biallelic BRCA1 mutations have not been confirmed, presumably because one wild-type BRCA1 allele is required during embryogenesis. This study describes an individual(More)
During the last 30 years, key advances in the field of cancer genetics have improved identification of high-risk families in which cancer risk can be linked to mutations in cancer susceptible genes. Identification of individuals with heritable cancer risk may influence short- and long-term medical management issues. Heightened screening and risk reducing(More)
PURPOSE Clinical testing for germ-line variation in multiple cancer susceptibility genes is available using massively parallel sequencing. Limited information is available for pretest genetic counseling regarding the spectrum of mutations and variants of uncertain significance in defined patient populations. METHODS We performed massively parallel(More)
BACKGROUND Men with germline breast cancer 1, early onset (BRCA1) or breast cancer 2, early onset (BRCA2) gene mutations have a higher risk of developing prostate cancer (PCa) than noncarriers. IMPACT (Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted screening in BRCA1/2 mutation carriers and controls) is an international(More)
The bones are the most common sites of breast cancer metastasis. Upon arrival within the bone microenvironment, breast cancer cells coordinate the activities of stromal cells, resulting in an increase in osteoclast activity and bone matrix degradation. In late stages of bone metastasis, breast cancer cells induce apoptosis in osteoblasts, which further(More)
BACKGROUND This study sought to estimate the risk of breast cancer (BC) after a diagnosis of ovarian cancer (OC) associated with mutation of the BRCA1/2 (breast cancer, early onset) genes (BRCA-OC). METHODS The Memorial Sloan-Kettering Cancer Center and the University of Pennsylvania, clinical genetics databases were searched to identify women with(More)
