Cells with distinct phenotypes including stem-cell-like properties have been proposed to exist in normal human mammary epithelium and breast carcinomas, but their detailed molecular characteristics and clinical significance are unclear. We determined gene expression and genetic profiles of cells purified from cancerous and normal breast tissue using markers(More)
Research on the prevention of depressive symptoms in children and adolescents was reviewed and synthesized with meta-analysis. When all 30 studies were included, selective prevention programs were found to be more effective than universal programs immediately following intervention. Both selective and indicated prevention programs were more effective than(More)
OBJECTIVE To provide recommendations for cancer surveillance and risk reduction for individuals carrying mutations in the BRCA1 or BRCA2 genes. PARTICIPANTS A task force with expertise in medical genetics, oncology, primary care, gastroenterology, and epidemiology convened by the Cancer Genetics Studies Consortium (CGSC), organized by National Human(More)
The cognitive diathesis-stress model of depression was tested in a sample of 439 children in grades 5 and 6. Attributional style and cognitions about academic competence and control over achievement were assessed before the occurrence of a potentially stressful event--receiving unacceptable grades on a report card. Depressive symptoms were assessed 1 week(More)
This prospective study examined the contribution of maternal history of depression, mothers' cognitive style, mothers' parenting style, and stressful life events to depressive cognitions in 240 young adolescents. Mothers and adolescents were assessed annually over 3 years starting in sixth grade. The cognitions examined were derived from cognitive models of(More)
BACKGROUND Olaparib, a novel, orally active poly(ADP-ribose) polymerase (PARP) inhibitor, induced synthetic lethality in BRCA-deficient cells. A maximum tolerated dose and initial signal of efficacy in BRCA-deficient ovarian cancers have been reported. We therefore assessed the efficacy, safety, and tolerability of olaparib alone in women with BRCA1 or(More)
CONTEXT Mastectomy and salpingo-oophorectomy are widely used by carriers of BRCA1 or BRCA2 mutations to reduce their risks of breast and ovarian cancer. OBJECTIVE To estimate risk and mortality reduction stratified by mutation and prior cancer status. DESIGN, SETTING, AND PARTICIPANTS Prospective, multicenter cohort study of 2482 women with BRCA1 or(More)
RAD51 is an important component of double-stranded DNA-repair mechanisms that interacts with both BRCA1 and BRCA2. A single-nucleotide polymorphism (SNP) in the 5' untranslated region (UTR) of RAD51, 135G-->C, has been suggested as a possible modifier of breast cancer risk in BRCA1 and BRCA2 mutation carriers. We pooled genotype data for 8,512 female(More)
Germline BRCA1 mutations predispose to breast cancer. To identify genetic modifiers of this risk, we performed a genome-wide association study in 1,193 individuals with BRCA1 mutations who were diagnosed with invasive breast cancer under age 40 and 1,190 BRCA1 carriers without breast cancer diagnosis over age 35. We took forward 96 SNPs for replication in(More)
BACKGROUND Data concerning the efficacy of bilateral prophylactic oophorectomy for reducing the risk of gynecologic cancer in women with BRCA1 or BRCA2 mutations are limited. We investigated whether this procedure reduces the risk of cancers of the coelomic epithelium and breast in women who carry such mutations. METHODS A total of 551 women with(More)
