BACKGROUND Although access to cancer care is known to influence patient outcomes, to the authors' knowledge, little is known regarding geographic access to cancer care, and how it may vary by population characteristics. This study estimated travel time to specialized cancer care settings for the continental U.S. population and calculated per capita(More)
BACKGROUND Little is known about the carcinogenic potential of arsenic in areas with low to moderate concentrations of arsenic (< 100 microg/L) in drinking water. OBJECTIVES We examined associations between arsenic and lung cancer. METHODS A population-based case-control study of primary incident lung cancer was conducted in 10 counties in two U.S.(More)
BACKGROUND Some epidemiologic and laboratory studies have suggested that total joint arthroplasty could increase the risk of cancer. In this meta-analysis, we attempt to clarify the association of joint arthroplasty with subsequent cancer incidence. METHODS We identified population-based studies reporting standardized incidence ratios (SIR) for cancer(More)
The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative,(More)
BACKGROUND We investigated risk factors for inflammatory breast cancer (IBC), a rare, aggressive, and poorly understood breast cancer that is characterized by diffuse breast skin erythema and edema. METHODS We included 617 IBC case subjects in a nested case-control study from the Breast Cancer Surveillance Consortium database (1994-2009). We also included(More)
PURPOSE To examine changes in screening mammogram interpretation as radiologists with and radiologists without fellowship training in breast imaging gain clinical experience. MATERIALS AND METHODS In an institutional review board-approved HIPAA-compliant study, the performance of 231 radiologists who interpreted screen-film screening mammograms from 1996(More)
PURPOSE To identify radiologists' characteristics associated with interpretive performance in screening mammography. MATERIALS AND METHODS The study was approved by institutional review boards of University of Washington (Seattle, Wash) and institutions at seven Breast Cancer Surveillance Consortium sites, informed consent was obtained, and procedures(More)
PURPOSE To examine whether U.S. radiologists' interpretive volume affects their screening mammography performance. MATERIALS AND METHODS Annual interpretive volume measures (total, screening, diagnostic, and screening focus [ratio of screening to diagnostic mammograms]) were collected for 120 radiologists in the Breast Cancer Surveillance Consortium(More)
PURPOSE To investigate the association between radiologist interpretive volume and diagnostic mammography performance in community-based settings. MATERIALS AND METHODS This study received institutional review board approval and was HIPAA compliant. A total of 117,136 diagnostic mammograms that were interpreted by 107 radiologists between 2002 and 2006 in(More)
BACKGROUND Diagnostic test sets are a valuable research tool that contributes importantly to the validity and reliability of studies that assess agreement in breast pathology. In order to fully understand the strengths and weaknesses of any agreement and reliability study, however, the methods should be fully reported. In this paper we provide a(More)
