BACKGROUND Use of the conventional Western and Japanese classification systems of gastrointestinal epithelial neoplasia results in large differences among pathologists in the diagnosis of oesophageal, gastric, and colorectal neoplastic lesions. AIM To develop common worldwide terminology for gastrointestinal epithelial neoplasia. METHODS Thirty one(More)
In this paper, we review the histological features of coeliac disease and propose a standardized report scheme based on the Marsh classification. Furthermore, terms used by pathologists are defined. The most important histological differential diagnoses are given, as well as a definition of the different clinical forms of coeliac disease such as(More)
BACKGROUND The course of Crohn's disease is characterised by the occurrence of intestinal complications such as strictures, intra-abdominal fistulas, or abscesses. Standard diagnostic procedures may fail to show these complications, in particular fistulas. AIMS To test the value of transabdominal bowel sonography (T) for the detection of intestinal(More)
BACKGROUND & AIMS In the absence of pathognomonic markers for Crohn's disease (CD) and ulcerative colitis (UC), the diagnosis of inflammatory bowel disease depends on a compendium of clinical, radiographic, endoscopic, and histologic criteria that bears imperfect specificity to the individual disorders. In 10% of cases of colitis, no differentiation can be(More)
Intraepithelial lymphocytes (IELs) and lamina propria lymphocytes (LpLs) have not been well studied in gastric mucosa, particularly in lymphocytic gastritis. Therefore, they were immunohistologically characterized with antibodies recognizing CD3, CD8, CD57, T cell-restricted intracellular antigen (TIA-1), and granzyme B (GrB). The TIA-1 labels cytotoxic(More)
Hypoxia-inducible factor 1alpha (HIF-1alpha) is a transcriptional factor that regulates genes involved in response to hypoxia and promotes neoangiogenesis, which are considered essential for tumor growth and progression. Using immunohistochemistry, we investigated the influence of HIF-1alpha expression on prognosis in 91 patients with cervical cancer stage(More)
Detection and typing of human papillomavirus (HPV) infection may have a major impact in cervical-screening and follow-up. In this study various commercially available techniques for the detection of HPV were evaluated. HPV-status was determined in 86 samples of cervical cancer by PCR and direct sequencing, catalyzed signal amplified colorimetric DNA in situ(More)
PURPOSE Hypoxia-inducible factor (HIF)-1alpha is a transcription factor that supports the adaptation of human cancer cells to hypoxia and is involved in various pathways supporting tumor growth and progression. The aim of this study was to determine the prognostic influence of HIF-1alpha expression in patients with advanced-stage breast cancer, evident by(More)
PURPOSE The purpose of this study was to investigate the prognostic significance of assessment of human epidermal growth factor receptor (HER)-2 oncogene protein overexpression of breast cancer tissue by the United States Food and Drug Administration (FDA)-approved HercepTest and grading system (negative, 0 or 1+; weakly positive, 2+; strongly positive,(More)

The diagnosis of celiac disease (CD) is based upon histologic findings in duodenal or jejunal biopsies. In the past few years it has turned out that the development of CD lesion in the small bowel is a dynamic process which may present in various histologic forms. At one end of the spectrum is a mucosa with normal architecture and an increase in(More)
