Prognostic Value of Immunohistochemical Expression of Beta-1 Integrin in Pancreatic Carcinoma
1999
<i>Background: </i>Prognostically relevant factors based on the histological assessment of the resected pancreas are known. However, the knowledge of additional factors associated with the prognosis is helpful in planning the therapy for an individual patient. β<sub>1</sub> Integrin expression is known to have a prognostic influence in some malignant tumors. No data are, however, available on the prognostic value of β<sub>1</sub> integrins in pancreatic carcinoma. <i>Method: </i>We investigated paraffin-embedded specimens of 19 patients undergoing surgical treatment for periampullary carcinoma and of 42 patients for ductal pancreatic carcinoma…
Treatment of advanced adenocarcinomas of the exocrine pancreas and the gallbladder with 5-fluorouracil, high dose levofolinic acid and oral hydroxyur…
1996
BACKGROUND To date there is no established chemotherapeutic treatment for patients with unresectable locally advanced and/or metastatic carcinomas of the exocrine pancreas or the gallbladder. A multicenter Phase II trial has been performed by the Southern Italy Oncology Group with the aim of evaluating the clinical effectiveness and tolerability of weekly 5-fluorouracil (5-FU) in modulation with intravenous (i.v.) high dose levofolinic acid and oral hydroxyurea. METHODS A total of 70 patients fulfilling the standard eligibility for a Phase II study were enrolled in the trial. Forty patients had advanced pancreatic adenocarcinoma and 30 had advanced gallbladder carcinoma. The treatment sched…
Effectiveness of Enteric-Coated Preparations on Nutritional Parameters in Cystic Fibrosis
1988
To evaluate the effectiveness of enteric-coated pancreatic enzyme supplements in comparison to conventional preparations of ingested enzyme on growth and nutritional parameters of patients with cystic fibrosis, we conducted a long-term study involving 40 patients. The data reproduced here were recorded after 6 months of therapy with powder-containing capsules or with enteric-coated products. Fat absorption was estimated by measurement of steatorrhoea with the steatocrit method. All parameters studied improved after enteric-coated pancreatic enzyme therapy, with a statistically significant increase in weight, cholesterol and haemoglobin values. Furthermore, the number of patients with positi…
Pancreatic Endoscopic Sphincterotomy in Patients with Chronic Pancreatitis: A Single-Center Experience in 171 Consecutive Patients
2002
Background and Study Aims: In recent years, interest in endoscopic therapy techniques for pancreatic diseases has been constantly increasing. The aim of the present study was to assess the technical success, technique, and complications of endoscopic pancreatic sphincterotomy (EPS) in patients with chronic pancreatitis. Patients and Methods: A total of 171 patients with chronic pancreatitis and abdominal complaints were identified in whom at least one attempt at EPS was carried out. During the procedure, sphincterotomy was carried out using a guide-wire sphincterotome or a needle-knife papillotome. Patients were followed up after EPS for at least 24 h, including clinical symptoms and labora…
In vivo reprogramming for tissue repair.
2015
Berninger and colleagues define milestones for in vivo reprogramming and discuss recent developments in reprogramming into pancreatic b-cells and neurons. Vital organs such as the pancreas and the brain lack the capacity for effective regeneration. To overcome this limitation, an emerging strategy consists of converting resident tissue-specific cells into the cell types that are lost due to disease by a process called in vivo lineage reprogramming. Here we discuss recent breakthroughs in regenerating pancreatic β-cells and neurons from various cell types, and highlight fundamental challenges that need to be overcome for the translation of in vivo lineage reprogramming into therapy.
Thymidine-dependent Staphylococcus aureus small-colony variants: human pathogens that are relevant not only in cases of cystic fibrosis lung disease.
2008
ABSTRACT We report the isolation of thymidine-dependent small-colony variants (TD-SCVs) of Staphylococcus aureus from unusual infection sites of patients with chronic soft tissue infection, tympanitis, bronchitis, peritonitis, and septicemia. Furthermore, we provide evidence that the essential growth factor for TD-SCVs, i.e., thymidine, and its metabolite dTMP are present in various human specimens.
Robotic pancreatic surgery: old concerns, new perspectives.
2018
Background: Described for the first time in 2003, the robotic pancreatic surgery shows interesting results. The evaluation of post-operative outcomes is necessary once we describe an innovative surgical approach. Methods: We have performed a retrospective analysis of a prospectively maintained database on robotic pancreatic surgery including malignant and benign indications for surgery. Results: A total of 50 consecutive patients underwent robotic pancreatic surgery (26 pancreatico duodenectomy and 24 distal pancreatectomy) between January 2012 and July 2015 in a single centre. The overall operative time was 425 (390–620) min. In a subgroup of highly selected malignant tumours, we were able…
Pancreatoduodenectomy with artery-first approach.
2019
"Artery-first approach" encompasses different aspects for the surgical treatment of pancreatic cancer. It is a surgical technique or set of techniques which share in common the dissection of the main arterial vasculature involved in pancreatic cancer, before any irreversible surgical step is performed. On the other hand it represents the need for a meticulous dissection of the arterial planes and clearing of the retropancreatic tissue between the superior mesenteric artery, the common hepatic artery and portal vein in an attempt to achieve R0 resections. The recent expansion of this approach is based mainly on three factors: venous involvement should not be considered a contraindication for…
Treatment of tumors of the pancreatic head with suspected but unproved malignancy: is a nihilistic approach justified?
1999
The aim of the present prospective observational study was to evaluate the accuracy of preoperative imaging studies and the outcome of patients after pancreaticoduodenectomy for suspected but unproved malignancy. Pancreaticoduodenectomy was performed in 186 patients with a suspected but histologically unproved malignancy of the pancreatic head: 86 with a ductal pancreatic carcinoma, 56 with a periampullary tumor, 18 with a cystadenocarcinoma, 13 with a rare malignant tumor or a metastasis, and 13 with a benign tumor. An accurate differentiation between a ductal pancreatic carcinoma and a nonductal tumor or a benign tumor was neither possible with tumor marker CA 19-9 nor with diagnostic ima…
GADD45α is highly expressed in pancreatic ductal adenocarcinoma cells and required for tumor cell viability
2005
Pancreatic ductal adenocarcinoma is one of the most common causes of cancer death in the western civilization. Recently, NF-kappaB has been shown to be activated in pancreatic ductal adenocarcinoma through constitutive activation of IkappaB kinase (IKK). Inhibition of NF-kappaB by a super-inhibitor of NF-kappaB--delta-N-IkappaBalpha--resulted in impaired proliferation and induction of apoptosis, suggesting an important role of NF-kappaB in pancreatic tumorigenesis. Downstream target genes of IkappaBalpha have not been elucidated in pancreatic ductal adenocarcinoma in detail. Using expression profiling by cDNA array analysis of pancreatic ductal adenocarcinoma cell lines stably transfected w…
