Purpose Neuroendocrine tumors (NETs) are considered rare tumors and can produce a variety of hormones. In this study, we examined the epidemiology of and prognostic factors for NETs, because a thorough examination of neither had previously been performed. Methods The Surveillance, Epidemiology, and End Results (SEER) Program registries were searched to(More)
Introduction. Actual 5-year survival rates of 10–18% have been reported for patients with resected pancreatic adenocarcinoma (PC), but the use of multimodality therapy was uncommon in these series. We evaluated long-term survival and patterns of recurrence in patients treated for PC with contemporary staging and multimodality therapy. Methods. We analyzed(More)
PURPOSE The role of carbohydrate antigen (CA) 19-9 in the evaluation of patients with resectable pancreatic cancer treated with neoadjuvant therapy prior to planned surgical resection is unknown. We evaluated CA 19-9 as a marker of therapeutic response, completion of therapy, and survival in patients enrolled on two recently reported clinical trials. (More)
OBJECTIVE To better understand the impact of a microscopically positive margin (R1) on patterns of disease recurrence and survival after pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma. SUMMARY BACKGROUND DATA A positive resection margin after PD is considered to be a poor prognostic factor, and some have proposed that an R1 margin may be a(More)
Major vascular resection performed at the time of pancreaticoduodenectomy (PD) for adenocarcinoma remains controversial. We analyzed all patients who underwent vascular resection (VR) at the time of PD for any histology at a single institution between 1990 and 2002. Preoperative imaging criteria for PD included the absence of tumor extension to the celiac(More)
Pancreatic adenocarcinoma is the fifth leading cause of cancer-related death in the U.S. In spite of advancements in surgical treatment, nearly 80% of patients thought to have localized pancreatic cancer die of recurrent or metastatic disease when treated with surgery alone. Therefore, efforts to alter the patterns of recurrence and improve survival for(More)
Caroli's Disease (CD) is a rare congenital disorder characterized by cystic dilatation of the intrahepatic bile ducts. This report describes a patient with cholangiocarcinoma arising in the setting of monolobar CD. In spite of detailed investigations including biliary enteric bypass and endoscopic retrograde cholangiography, the diagnosis of mucinous(More)
The effect of in vitro expansion of human adipose-derived stem cells (ASCs) on stem cell properties is controversial. We examined serial subcultivation with expansion on the ability of ASCs to grow and differentiate into osteoblastic lineages. Flow cytometric analysis, growth kinetics, cell population doubling time, light microscopy and confocal analysis,(More)
The present dataset describes a detailed protocol to isolate mesenchymal cells from human fat without the use of collagenase. Human fat specimen, surgically cleaned from non-fat tissues (e.g., blood vessels) and reduced into smaller fat pieces of around 1-3 mm size, is incubated in complete culture media for five to seven days. Then, cells started to spread(More)
