PURPOSE Serum-biomarker based screening for pancreatic cancer could greatly improve survival in appropriately targeted high-risk populations. EXPERIMENTAL DESIGN Eighty-three circulating proteins were analyzed in sera of patients diagnosed with pancreatic ductal adenocarcinoma (PDAC, n = 333), benign pancreatic conditions (n = 144), and healthy control(More)
BACKGROUND AND STUDY AIMS Perforations during endoscopic retrograde cholangiopancreatography (ERCP) are rare, and the management of these perforations is variable, with some patients requiring immediate surgery and others only conservative management. We reviewed all ERCP-related perforations at our institution to determine: a) their incidence; b) clinical(More)
BACKGROUND EUS-guided fine needle aspiration (EUS-FNA) is a highly accurate method of detecting malignant lymphadenopathy. The optimal methods for performing EUS-FNA to maximize sensitivity and to minimize the number of needle passes necessary are unknown. This is a report of the results of a prospective randomized controlled trial to determine the effect(More)
BACKGROUND The current TNM classification system does not consider tumor length or the number of lymph nodes in the staging and classification scheme for patients with esophageal carcinoma. Using data from the National Cancer Institute SEER Program, the authors explored the effect of tumor length and number of positive lymph nodes on survival in patients(More)
BACKGROUND The relationship between hospital procedure volume and outcome has been recognized for various specialties and procedures. Although increasingly used and in existence for 40 years, to date, data on the relationship between hospital volume and outcome of ERCP are scant. OBJECTIVE We sought to examine health-related outcomes after ERCP in(More)
Whether tissue diagnosis is required in the preoperative evaluation of patients with suspected pancreatic cancer remains controversial. We prospectively evaluated the accuracy, safety, and potential impact on surgical intervention of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the preoperative evaluation of suspected pancreatic cancer.(More)
BACKGROUND AND OBJECTIVE The additional diagnostic value of endoscopic ultrasound-fine needle aspiration (EUS-FNA) over lymph node (LN) echofeatures alone in evaluating lymphadenopathy is unknown. The objectives of this study are (1) to prospectively evaluate the utility of EUS-FNA in evaluating mediastinal or peri-intestinal lymphadenopathy and to compare(More)
BACKGROUND The subgroup of patients with gastroesophageal reflux disease (GERD) that should undergo endoscopy to rule out Barrett's esophagus (BE) has not been well defined. GOALS To examine demographic and clinical variables predictive of BE before endoscopy. STUDY A validated GERD questionnaire was administered to 107 patients with biopsy-proven BE(More)
OBJECTIVES Screening for hepatocellular carcinoma (HCC) is advocated in cirrhotic patients to optimize early detection and treatment. However, the cost-effectiveness is not well defined. Our objective was to perform a cost-utility analysis from a third-party payer's perspective of no screening, alpha-fetoprotein (AFP) concentration measurement alone,(More)
