The integrated likelihood (also called the marginal likelihood or the normalizing constant) is a central quantity in Bayesian model selection and model averaging. It is defined as the integral over the parameter space of the likelihood times the prior density. The Bayes factor for model comparison and Bayesian testing is a ratio of integrated likelihoods,(More)
The identification of genes that contribute to the biological basis for clinical heterogeneity and progression of prostate cancer is critical to accurate classification and appropriate therapy. We performed a comprehensive gene expression analysis of prostate cancer using oligonucleotide arrays with 63,175 probe sets to identify genes and expressed(More)
PURPOSE To prospectively determine the impact of genetic counseling and testing on risk-reduction strategies and cancer incidence in a cohort of individuals at hereditary risk for breast and ovarian cancer. PATIENTS AND METHODS Two hundred fifty-one individuals with BRCA mutations were identified at a single comprehensive cancer center from May 1, 1995,(More)
BACKGROUND Risk-reducing salpingo-oophorectomy is often considered by carriers of BRCA mutations who have completed childbearing. However, there are limited data supporting the efficacy of this approach. We prospectively compared the effect of risk-reducing salpingo-oophorectomy with that of surveillance for ovarian cancer on the incidence of subsequent(More)
The prognostic significance of germline mutations in BRCA1 and BRCA2 in women with breast cancer remains unclear. A combined analysis was performed to address this uncertainty. Two retrospective cohorts of Ashkenazi Jewish women undergoing breast-conserving treatment for invasive cancer between 1980 and 1995 (n = 584) were established. Archived tissue(More)
Fanconi anemia (FA) is an autosomal recessive disorder characterized by cellular hypersensitivity to DNA cross-linking agents and cancer predisposition. Recent evidence for the interactions of ataxia-telangiectasia mutated protein ATM and breast cancer susceptibility proteins BRCA1 and BRCA2 (identified as FANCD1) with other known FA proteins suggests that(More)
The androgen-signaling pathway is critical to the development and progression of prostate cancer and androgen ablation is a mainstay of therapy for this disease. We performed a genome-wide expression analysis of human prostate cancer during androgen ablation therapy to identify genes regulated by androgen and genes differentially expressed after the(More)
BACKGROUND Fanconi anemia (FA) is a rare autosomal recessive disorder characterized by a high degree of genomic instability and predisposition to cancer development. Recent evidence suggests that the incidence of head and neck squamous cell carcinoma (HNSCC) may be increased in patients with FA. OBJECTIVE To determine the cumulative incidence, tumor(More)
Markov chain Monte Carlo (MCMC) techniques are applied to simultaneously identify multiple quantitative trait loci (QTL) and the magnitude of their effects. Using a Bayesian approach a multi-locus model is fit to quantitative trait and molecular marker data, instead of fitting one locus at a time. The phenotypic trait is modeled as a linear function of the(More)
Toll-like receptors (TLRs) transmit signals in response to Aspergillus fumigatus conidia and hyphae. In this preliminary study, we examined the association between single nucleotide polymorphisms (SNPs) in TLR1, TLR4, and TLR6 genes and development of invasive aspergillosis (IA) in 127 allogeneic hematopoietic stem cell transplant recipients consisting of(More)
