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)
INTRODUCTION Early detection of breast cancer by screening mammography aims to increase treatment options and decrease mortality. Recent studies have shown inconsistent results in their investigations of the possible association between travel distance to mammography and stage of breast cancer at diagnosis. OBJECTIVE The purpose of the study was to(More)
BACKGROUND Self-reported screening behaviors from national surveys often overestimate screening use, and the amount of overestimation may vary by demographic characteristics. We examine self-report bias in mammography screening rates overall, by age, and by race/ethnicity. METHODS We use mammography registry data (1999-2000) from the Breast Cancer(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)
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)
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)
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)
IMPORTANCE A breast pathology diagnosis provides the basis for clinical treatment and management decisions; however, its accuracy is inadequately understood. OBJECTIVES To quantify the magnitude of diagnostic disagreement among pathologists compared with a consensus panel reference diagnosis and to evaluate associated patient and pathologist(More)
PURPOSE The aim of this study was to assess agreement of mammographic interpretations by community radiologists with consensus interpretations of an expert radiology panel to inform approaches that improve mammographic performance. METHODS From 6 mammographic registries, 119 community-based radiologists were recruited to assess 1 of 4 randomly assigned(More)
OBJECTIVES Detection and removal of adenomas and clinically significant serrated polyps (CSSPs) is critical to the effectiveness of colonoscopy in preventing colorectal cancer. Although longer withdrawal time has been found to increase polyp detection, this association and the use of withdrawal time as a quality indicator remains controversial. Few studies(More)
