Oxidative DNA damage is thought to play an important part in the pathogenesis of H. pylori-induced mucosal damage. 8-OHdG is a sensitive marker of DNA oxidation and is repaired by a polymorphic glycosylase (OGG1) more effectively than by OGG1-Cys(326). The aims of this study were to ascertain the respective roles of H. pylori, cagA status and OGG1(More)
Esophageal carcinoma is among the cancers with the worst prognosis. Real chances for cure depend on both early recognition and early treatment. The ability to predict lymph node involvement allows early curative treatment with less invasive approaches. To determine clinicohistopathological criteria correlated with lymph node involvement in patients with(More)
BACKGROUND In the general population, Helicobacter pylori (H. pylori), particularly the cagA positive strain, has been associated with intestinal-type gastric carcinoma. Gastric carcinomas are rarely observed in patients age < or = 40 years. Host-related factors have been thought to be more important than environmental agents in these early-onset cancers.(More)
Crohn's disease can affect the upper gut withreported variable frequency, although concurrentHelicobacter pylori infection has been reported to below. We prospectively investigated the prevalence of esophageal, gastric, and duodenal lesions andHelicobacter pylori infection in 67 Crohn's disease, 41ulcerative colitis patients, and 43 controls.(More)
The major symptom at diagnosis of endometrial cancer is post-menopausal bleeding; it is present in around 90% of cases. Singular bone metastasis is described as an uncommon site for endometrial cancer at diagnosis, showing in just 5-6% of cases. In this report we describe a rare presentation of a singular bone metastasis because of endometrial cancer of a(More)
BACKGROUND Infection with Helicobacter pylori is a major risk factor for the development of atrophic gastritis and gastric cancer. H. pylori strains can differ with respect to the presence of cagA (cytotoxin-associated gene A), a gene encoding a high-molecular-weight immunodominant antigen. H. pylori strains possessing cagA have been associated with(More)
BACKGROUND Determining both the frequency and the spectrum of p53 gene mutation in young patients with gastric cancer might provide clues to the host related genetic mechanism(s) in gastric carcinogenesis. PATIENTS AND METHODS p53 mutations were assessed (by means of polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), followed by(More)
BACKGROUND The cancer risk associated with gastric non-invasive neoplasia (formerly dysplasia) is debated. This prospective long term follow up study investigates the clinicopathological behaviour of non-invasive gastric neoplasia (and related lesions), focusing on the cancer risk associated with each different histological phenotype. PATIENTS AND METHODS(More)
tumors that account for 2 % to 13.6 % of all gastrointestinal carcinoids, and no guidelines are available for their treat− ment. Small (< 2 cm) nonperiampullary duodenal carcinoids without submucosal invasion have been termed early stage duodenal carcinoids (esDC) [1]; their clinical course appears favorable and en− doscopic treatment would seem to be a(More)
