Endoscopic therapy of adenomas of the papilla of Vater. A retrospective analysis with long-term follow-up.
2001
Abstract Aims. To compare the efficacy and the complication rate between endoscopic snare resection of adenomas of Vater's papilla and endoscopic palliation. Methods. In a retrospective, non randomized manner, we compared long-term results of our endoscopic strategies in 36 patients with histologically confirmed adenoma of Vater's papilla submitted either to local endoscopic snare resection (n=18) or to simple endoscopic palliation (n=18), respectively. Results. Between 1985 and 1998 results were reviewed. Median age was 76.5 (range 42–89) years in the palliation, and 64.0(23–89) years in the endoscopic snare resection group. Median duration of follow-up was 33 (6–135) and 75.0 (27–123) mon…
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…
Promyelocytic leukemia (PML) gene expression is a prognostic factor in ampullary cancer patients
2008
Background: Promyelocytic leukemia (PML) tumor suppressor gene plays a key role in acute PML pathogenesis but its involvement in pathogenesis and prognosis of solid cancers has not been defined yet. Patients and methods: In all, 62 ampullary adenocarcinoma patients who underwent curative surgery between 1996 and 2005 were included. Expression analysis of PML was carried out by immunohistochemical staining and correlated with disease-free survival (DFS) and overall survival (OS). Results: In 24 tumor specimens (38.7%), PML was classified as absent, in 16 (25.8%) as focally expressed and in 22 (35.5%) as diffusely expressed. By univariate analysis, DFS was significantly influenced by patholog…
Schwannoma of the common bile duct: a rare cause of obstructive jaundice.
2003
The endoscopic diagnosis of bile duct lesions has improved over recent years through the introduction of cholangioscopy and intraductal ultrasound. Combining this with biopsies examined using routinely administered immunohistochemical markers, the diagnosis of tumors of the extrahepatic bile duct can be improved substantially. We report a rare case of a schwannoma of the bile duct causing obstructive jaundice.
Risk factors for extrahepatic biliary tract carcinoma in men: medical conditions and lifestyle: results from a European multicentre case-control stud…
2007
OBJECTIVES: To identify risk factors of carcinoma of the extrahepatic biliary tract in men. METHODS: Newly diagnosed and histologically confirmed patients, 35-70 years old, were interviewed between 1995 and 1997 in Denmark, Sweden, France, Germany and Italy. Population controls were frequency-matched by age and region. Adjusted odds ratios and 95%-confidence intervals were estimated by logistic regression. RESULTS: The analysis included 153 patients and 1421 controls. The participation proportion was 71% for patients and 61% for controls. Gallstone disease was corroborated as a risk factor for extrahepatic biliary tract carcinoma in men (odds ratio 2.49; 95% confidence interval 1.32-4.70), …
Extranodal extension in N1-adenocarcinoma of the pancreas and papilla of Vater: A systematic review and meta-analysis of its prognostic significance
2016
The aim of the study was to investigate the prognostic role of extranodal extension (ENE) of lymph node metastasis in adenocarcinoma of the pancreas (PDAC) and papilla [cancer of the papilla of Vater (CPV)]. A PubMed and SCOPUS search from database inception until 5 January 2015 without language restrictions was conducted. Eligible were prospective studies reporting data on prognostic parameters in individuals with PDAC and/or CPV, comparing participants with the presence of ENE (ENE +) with those with intranodal extension (ENE). Data were summarized using risk ratios for number of deaths/recurrences and hazard ratios for time-dependent risk related to ENE+, adjusted for potential confounde…
Neuroendocrine tumor of the common bile duct: case report
2017
Neuroendocrine tumors (NET) are a very heterogeneous group of neoplasms; in recent years we have seen an increase in their incidence (3.65 /100.000/year). They can be associated with hereditary endocrine syndromes (MEN, Von Hippel Lindau); they can occur at any age and the incidence is slightly higher in men than women. The aetiology of the neuroendocrine tumors is unclear; in most cases, inflammation of the bile ducts may be the underlying cause and for this reason, the initial patient's evaluation should be focused on the different aspects concerning the oncological one and the possible sequelae of the biliary obstructions that can evolve in biliary sepsis. All neuroendocrine tumors have …
