OBJECTIVES The aim of this study was to evaluate the prognostic value of nodal involvement in resected adenocarcinoma of the pancreatic head. METHODS For the period between 1980 and 2002, 96 patients underwent pancreaticoduodenectomy for pancreatic cancer. Lymph nodes were numbered and classified into groups according to the Japan Pancreatic Society(More)
BACKGROUND AND OBJECTIVES Lymph node involvement significantly affects survival of cancer patients. The aim of this study was to evaluate the importance of the number, ratio, and location of metastatic lymph nodes in ampullary cancers. METHODS Medical records of 111 patients who underwent curative pancreaticoduodenectomy for ampullary carcinomas were(More)
The purpose of the study was to assess risk factors for intestinal metaplasia arising from H. pylori-related chronic gastritis in a subset of the population referred to endoscopic examinations due to dyspeptic complaints. We aimed specifically to establish whether H. pylori itself may be responsible for the occurrence of intestinal metaplasia and to which(More)
The aim of the study was to test applycability of neural networks to classification of pancreatic intraductal proliferative lesions basing on nuclear features, especially chromatin texture. Material for the study was obtained from patients operated on for pancreatic cancer, chronic pancreatitis and other tumours requiring pancreatic resection. Intraductal(More)
Pancreatic intraepithelial neoplasia is only partially defined. Any attempt to establish the diagnostic criteria of early pancreatic carcinoma has been unsuccessful so far. In the present study we investigate expression of HER-2/neu in hyperplastic pancreatic duct epithelium. Material included resected pancreatic tissue obtained from 13 patients with(More)
Assessment of tumor proliferation rate using Bromodeoxyuridine labeling index (BrdUrdLI) as a possible predictor of rectal cancer response to preoperative radiotherapy (RT). Ninety-two patients were qualified either to short RT (5 Gy/fraction/5 days) and surgery about 1 week after RT (schedule I), or to short RT and 4–5 weeks interval before surgery(More)
The expression of the CD44 antigen and its isoforms is found in many normal and malignant tissues. Numerous studies indicate that the antigen affects the course of the disease, and its v6 isoform exerts a particularly negative effect on the prognosis. High CD44s (standard) and v6 isoform expression has been noted in pancreatic cancer. A similarly common(More)
Vaccination against pertussis has been performed since 1960. Whole cell pertussis vaccine produced by Plant of Sera and Vaccines Biomed S.A. in Kraków, has been used. After vaccination has been introduced, epidemiological situation of pertussis in Poland improved, but in 90's the decrease of immunity was observed. The aim of this work was to determine(More)
The increasing frequency and poor prognosis in pancreatic cancer prompt us to search for morphological lesions being a substrate for its development. Studies of autopsy and surgically resected material as well as recent molecular studies have proved that one of the possible pathways of pancreatic neoplasia is the intraepithelial(More)
A sensitive catalytic voltammetric method for determining trace iron at a bismuth film electrode (BiFE) is described. The method is based on the cathodic reduction of the Fe(III)-triethanolamine (TEA) complex to Fe(II). It has been proved that the addition of KBrO3 causes rapid oxidation of Fe(II) and TEA, and therefore results in a large increase in the(More)
