BACKGROUND Colorectal cancer (CRC) is the second leading cause of cancer death in the United States, and endoscopic screening can both detect and prevent cancer, but utilization is suboptimal and varies across geographic regions. We use multilevel regression to examine the various predictors of individuals' decisions to utilize endoscopic CRC screening.(More)
OBJECTIVES We study a cohort of Medicare-insured men and women aged 65+ in the year 2000, who lived in 11 states covered by Surveillance, Epidemiology, and End Results (SEER) cancer registries, to better understand various predictors of endoscopic colorectal cancer (CRC) screening. METHODS We use multilevel probit regression on two cross-sectional periods(More)
OBJECTIVES Examine how differences in state regulatory environments predict geographic disparities in the utilization of cancer screening. DATA SOURCES/SETTING 100% Medicare fee-for-service population data from 2001-2005 was developed as multi-year breast (BC) and colorectal cancer (CRC) screening utilization rates in each county in the US. STUDY DESIGN(More)
In the United States, renal cell carcinoma (RCC) has rapidly increased in incidence for over two decades. The most common histologic subtypes of RCC, clear cell, papillary, and chromophobe have distinct genetic and clinical characteristics; however, epidemiologic features of these subtypes have not been well characterized, particularly regarding any(More)
BACKGROUND Colorectal and breast cancers are the second most common causes of cancer deaths in the US. Population cancer screening rates are suboptimal and many cancers are diagnosed at an advanced stage, which results in increased morbidity and mortality. Younger populations are more likely to be diagnosed at a later stage, and this age disparity is not(More)
BACKGROUND This community-based intervention study examined the effects of 2 different message strategies for presenting information about the prostate specific antigen (PSA) test. METHODS A quasi-experimental longitudinal design with 2 intervention and 1 control group. RESULTS Knowledge increased significantly among participants who received either(More)
We determined whether the current SEER registries are representative of the nation’s cancer cases or the socio-demographic characteristics. We used breast cancer (BC) and colorectal cancer (CRC) cases diagnosed 2004–2009 from the US Cancer Statistics (USCS) database. Cases were classified into groups residing in SEER coverage areas and the other areas. We(More)
Safety net hospitals (SNHs) have played a critical role in the U.S. health system providing access to health care for vulnerable populations, in particular the Medicaid and uninsured populations. However, little research has examined how access for these populations changes when contraction of the safety net occurs. Institutional policies, such as hospital(More)
