The neutrophil/lymphocyte ratio (NLR) has recently been described as a predictor of mortality in patients who undergo percutaneous coronary intervention. The aim of this study was to investigate the utility of admission NLRs in predicting outcomes in patients with acute coronary syndromes (ACS). A total of 2,833 patients admitted to the University of(More)
Despite a known optimal treatment protocol for the management of glioblastoma multiforme (GBM), many patients fail to receive complete surgical resection or post-operative radiation therapy (PORT). The underlying reasons behind this disparity are unclear. Our study investigates the influence of regional health system resources on the surgical management and(More)
PURPOSE To evaluate trends in the geographic distribution of the radiation oncology (RO) workforce. METHODS AND MATERIALS We used the 1995 and 2007 versions of the Area Resource File to map the ratio of RO to the population aged 65 years or older (ROR) within different health service areas (HSA) within the United States. We used regression analysis to(More)
OBJECTIVE To determine whether there is an association between dermatologist density and melanoma mortality. DESIGN A regression model was developed to test the association between melanoma mortality and dermatologist density, controlling for county demographics, health care infrastructure, and socioeconomic factors. Data were collected from the Area(More)
BACKGROUND Combined temozolomide and radiotherapy (RT) is the standard postoperative therapy for glioblastoma multiforme (GBM). However, the clearest benefit of concurrent chemoradiotherapy (CRT) observed in clinical trials has been among patients who undergo surgical resection. Whether the improved survival with CRT extends to patients who undergo "biopsy(More)
BACKGROUND The distribution of radiation oncologists across the United States varies significantly among geographic regions. Accompanying these variations exist geographic variations in prostate cancer mortality. Prostate cancer outcomes have been linked to variations in urologist density, however, the impact of geographic variation in the radiation(More)
A sufficient cardiology workforce is necessary to ensure access to cardiovascular care. Specifically, access to cardiologists is important in the management and treatment of chronic cardiovascular disease. Given this, we examined the supply and distribution of the cardiologist workforce. In doing so, we mapped the ratios of cardiologists, primary care(More)

605 Background: Although the use of radiation therapy is increasing, there exists geographic variation among the distribution of radiation oncologists. The impact of this variation on colorectal cancer (CRC) outcomes remains unexplored. The goal of this study was to determine the effect of radiation oncologist density on CRC mortality. METHODS Using(More)

72 Background: There exists a geographic variation among the distribution of radiation oncologists (RO). The goal of this study was to determine the effect of RO density (ROD) on prostate cancer (PC) mortality (PCM). METHODS Using county- level data from the 2008 Area Resource File, National Program for Cancer Registries, and US Centers for Disease(More)
Radiation oncology encompasses a diverse spectrum of treatment modalities, including stereotactic radiosurgery, hypofractionated radiotherapy, and brachytherapy. Though all these modalities generally aim to do the same thing-treat cancer with therapeutic doses of radiation while relatively sparing normal tissue from excessive toxicity, the general(More)
