PURPOSE To evaluate for an association between 25-hydroxyvitamin D levels (vitamin D) and outcome measures in patients with melanoma after evaluation is controlled for systemic inflammatory response (SIR) on the basis of simultaneous C-reactive protein (CRP) measurement. MATERIALS AND METHODS Plasma samples from 1,042 prospectively observed patients with(More)
PURPOSE Adherence to evidence-based treatment guidelines has been proposed as a measure of cancer care quality. We sought to determine rates of and factors associated with adherence to the National Comprehensive Cancer Network (NCCN) treatment guidelines for colon cancer. PATIENTS AND METHODS Patients within the National Cancer Data Base treated for colon(More)
BACKGROUND The objective of the current study was to examine the impact of adherence to guidelines on stage-specific survival outcomes in patients with stage III and high-risk stage II colon cancer. The National Comprehensive Cancer Network (NCCN) has established working, expert consensus, and evidence-based guidelines for organ-specific cancer care,(More)
PURPOSE Health care access and advanced cancer stage are associated with oncologic outcomes for numerous common cancers. However, the impact of patient travel distance to health care on stage at diagnosis has not been well characterized. METHODS This study used a historical cohort of patients with colon cancer in the National Cancer Data Base from 2003(More)
BACKGROUND The purpose of this study was to determine the overall survival (OS) of patients with resectable gastric cancer treated with preoperative chemoradiation therapy and gastrectomy. STUDY DESIGN The medical records of patients with gastric adenocarcinoma presenting to our institution (January 1995 to August 2012) were reviewed to identify patients(More)
OBJECTIVE To ascertain whether the National Quality Forum-endorsed time interval for adjuvant chemotherapy (AC) initiation optimizes patient outcome. BACKGROUND Delayed AC initiation for stage III colon cancer is associated with worse survival and the focus of a National Quality Forum quality metric (<4 months among patients aged <80 years). METHODS(More)
OBJECTIVE To guide resource utilization, we aimed to determine the impact of routine surveillance imaging for the detection of melanoma recurrences amenable to surgical resection with curative intent. BACKGROUND The National Comprehensive Cancer Network guidelines for melanoma surveillance are largely consensus based. METHODS Using single-institution,(More)
BACKGROUND AND OBJECTIVES The purpose of this study was to identify clinicopathologic factors associated with overall survival (OS) in early T stage gastric cancer in a Western population. METHODS Patients with stage T1 or T2 gastric or gastroesophageal adenocarcinoma who had undergone upfront gastrectomy from 1995 to 2013 were identified in an(More)
BACKGROUND With increasing interest in neuroendocrine tumors (NETs), three staging systems for NETs of the colon and rectum have been published. Their prognostic relevance has not been examined and compared in an independent clinical database. METHODS From the National Cancer Database (NCDB), 5457 patients diagnosed with colorectal neuroendocrine tumor(More)
BACKGROUND To examine the baseline metabolic monitoring (MetMon) for second generation antipsychotics (SGA) among patients with schizophrenia in the Veterans Integrated Service Network (VISN) 16 of the Veterans Health Administration (VHA). METHODS VISN16 electronic medical records for 10/2002-08/2005 were used to identify patients with schizophrenia who(More)
