Ambient UVR and Environmental Arsenic Exposure in Relation to Cutaneous Melanoma in Iowa
Intermittent sun exposure is the major environmental risk factor for cutaneous melanoma (CM). Cumulative sun exposure and other environmental agents, such as environmental arsenic exposure, have not shown consistent associations. Ambient ultraviolet radiation (UVR) was used to measure individual total sun exposure as this is thought to be less prone to misclassification and recall bias. Data were analyzed from 1096 CM cases and 1033 controls in t…
Temporal Trends in Satellite-Derived Erythemal UVB and Implications for Ambient Sun Exposure Assessment
Ultraviolet radiation (UVR) has been associated with various health outcomes, including skin cancers, vitamin D insufficiency, and multiple sclerosis. Measurement of UVR has been difficult, traditionally relying on subject recall. We investigated trends in satellite-derived UVB from 1978 to 2014 within the continental United States (US) to inform UVR exposure assessment and determine the potential magnitude of misclassification bias created by ig…
Assessing physicians' intentions to talk about sex when they vaccinate nine-year-old to 15-year-old girls against HPV
The human papillomavirus (HPV) vaccine provides physicians with an opportunity to have conversations with girls about sex and sex-related topics. Current research suggests that these conversations are not happening. This study was designed to assess whether physicians would use the HPV vaccination as an opening to communicate with nine-year-old to 15-year-old female patients about sex using the Theory of Planned Behavior as a framework. The study…
Agreement of Medicare Claims and Tumor Registry Data for Assessment of Cancer-Related Treatment
BACKGROUND: Although health claims data are increasingly used in evaluating variations in patterns of cancer care and outcomes, little is known about the comparability of these data with tumor registry information. OBJECTIVES: To evaluate the agreement between Medicare claims and tumor registry data in measuring patterns of diagnostic and therapeutic procedures for older cancer patients. RESEARCH DESIGN: Analysis of a database linking Surveillanc…
The Utility of Medicare Claims Data for Measuring Cancer Stage
BACKGROUND: The validity of using claims data for measuring tumor stage, one of the most important determinants of choice of therapy and long-term survival, is unknown. OBJECTIVES: To determine the relative accuracy of both inpatient and hospital Outpatient Medicare claims for measuring the stage of disease of six commonly diagnosed cancers. RESEARCH DESIGN: Analysis of a database linking Surveillance, Epidemiology, and End Results (SEER) registr…
The Sensitivity of Medicare Claims Data for Case Ascertainment of Six Common Cancers
BACKGROUND: Although Medicare claims data have been used to identify cases of cancer in older Americans, there are few data about their relative sensitivity. OBJECTIVES: To investigate the sensitivity of diagnostic and procedural coding for case ascertainment of breast, colorectal, endometrial, lung, pancreatic, and prostate cancer. SUBJECTS: Three hundred and eighty nine thousand and two hundred and thirty-six patients diagnosed with cancer betw…
An ecological study of the effectiveness of mammography in reducing breast cancer mortality
OBJECTIVES: The purpose of this study was to determine the relation of screening mammography to breast cancer incidence and case fatality. METHODS: In a sample of White female Medicare beneficiaries hospitalized in 1990-1991, age-adjusted breast cancer incidence and 2-year case fatality rates were estimated and compared with the frequency of mammographic screening from a population-based survey. RESULTS: The average rates for incidence, case fata…
