PURPOSE Contrary to the extensive data accumulated regarding pancreatic carcinogenesis, the clinical and molecular features characteristic of advanced stage (stage III and IV) disease are unknown. A comprehensive study of pancreatic cancers from patients who have succumbed to their disease has the potential to greatly expand our understanding of the most(More)
BACKGROUND The PatientViewpoint website collects patient-reported outcomes and links them with the electronic health record to aid patient management. This pilot test evaluated PatientViewpoint's use, usefulness, and acceptability to patients and clinicians. METHODS This was a single-arm prospective study that enrolled breast and prostate cancer patients(More)
Pancreatic cancer is currently one of the deadliest of the solid malignancies. However, surgery to resect neoplasms of the pancreas is safer and less invasive than ever, novel drug combinations have been shown to improve survival, advances in radiation therapy have resulted in less toxicity, and enormous strides have been made in the understanding of the(More)
Assessing patient-specific risk factors for long-term mortality following resection of pancreatic adenocarcinoma can be difficult. Sarcopenia—the measurement of muscle wasting—may be a more objective and comprehensive patient-specific factor associated with long-term survival. Total psoas area (TPA) was measured on preoperative cross-sectional imaging in(More)
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Pancreatic Adenocarcinoma discuss the workup and management of tumors of the exocrine pancreas. These NCCN Guidelines Insights provide a summary and explanation of major changes to the 2012 NCCN Guidelines for Pancreatic Adenocarcinoma. The panel made 3 significant updates to the(More)
Survival for pancreatic ductal adenocarcinoma is low, the role of adjuvant therapy remains controversial, and recent data suggest adjuvant chemoradiation (CRT) may decrease survival compared with surgery alone. Our goal was to examine efficacy of adjuvant CRT in resected pancreatic adenocarcinoma compared with surgery alone. Patients with pancreatic(More)
Fifty-three patients with resected pancreatic adenocarcinoma were studied to determine if adjuvant chemo-radiation causes severe lymphopenia and if this is associated with adverse outcomes. Total lymphocyte counts (TLC) were normal in 91% before adjuvant chemo-radiation. Two months later, TLC fell by 63% (p < .0001) with 45% of patients having TLC < 500(More)
Hilar cholangiocarcinoma (HC) is a rare disease with a poor prognosis which typically presents in the 6(th) decade of life. Of the 3,000 cases seen annually in the United States, less than one half of these tumors are resectable. A variety of risk factors have been associated with HC, most notably primary sclerosing cholangitis (PSC), biliary stone disease(More)
Methodological limitations of prior studies have prevented progress in the treatment of patients with borderline resectable pancreatic adenocarcinoma. Shortcomings have included an absence of staging and treatment standards and pre-existing biases with regard to the use of neoadjuvant therapy and the role of vascular resection at pancreatectomy. In this(More)
OBJECTIVE The purpose of this study is to evaluate the performance of PET-derived parameters as prognostic markers for overall survival (OS) and progression-free survival (PFS) outcome in patients with pancreatic adenocarcinoma. MATERIALS AND METHODS We conducted a retrospective study of 106 patients (62 men and 44 women) with histologically proven(More)
