Helicobacter pylori (Hp) is thought to be a stomach carcinogen from epidemiological findings. To determine the effects of infection with the bacteria on experimental carcinogenesis, a study of the glandular stomach of Mongolian gerbils (MGs) was performed. Male MGs were treated with N-methyl-N'-nitro-N-nitrosoguanidine followed by inoculation with Hp or infected with Hp followed by N-methyl-N'-...

The aim of this study was to analyse changes in cancer mortality in Lithuania from 1978 to 2005. Materials and methods. Age-standardised mortality (World standard) rates were calculated for all the malignant neoplasms as well as for stomach, colorectal, lung, prostate, breast and cervical cancers. A joinpoint regression methodology was used to provide estimated annual percentage changes (EAPCs)...

BACKGROUND Endoscopic submucosal dissection (ESD) is a novel endoluminal technique that permits the resection of gastric neoplasms. AIM To analyse the feasibility of snaring as the final step of ESD. PATIENTS AND METHODS One hundred and ninety-nine consecutive gastric neoplasms resected by four ESD experts from January 2004 to May 2007 were investigated. Forty-five (22.6%) were finally rese...

A 56-year-old manwas referred to our department for evaluation of a gastric mass. His medical history revealed that he had undergone distal gastrectomy for an early gastric carcinoma 18 months previously. Abdominal computed tomography (CT) demonstrated a well-defined, contrastenhancing mass, 3.3cm in diameter, with uniform inner structure in the stomach (●" Fig.1). Esophagogastroduodenoscopy (E...

Summary. Leiomyoma is the most common type of mesenchymal tumor in esophagus (70-80 %) and second (about 45 stomach. But last 20 years, we can find only a small number publications devoted to them. And it leiomyoma mainly became subject differential-diagnostic comparison when evaluating other subepithelial neoplasms.
 Aim. Based on our own experience treating patients with upper gastrointe...

Several reports have recently focused on stromal tumors and their acute or chronic complications [1,2]. Gastro-Intestinal Stromal Tumors (GIST) are mesenchymal neoplasms that represent a small percentage of gastric cancers (1-3%) and arise more often from the stomach (60%) [3]. Expression of c-KIT (CD 117) in the tumor cells define their character in a proportion of 95% with the remaining 5% re...

BACKGROUND The kidney recipient is at a higher risk for cancer than is the general population, although the incidence of neoplasms in general is considered lower in Japan than in Western countries. The cause of this increased risk associated with either transplantation or geography has not yet been established. METHOD The incidences and sites of malignant neoplasms were analyzed in 285 kidney...

Objective: The dynamics of morbidity, disability and death rates due to malignant neoplasms in the population in Uralsk city of the Republic of Kazakhstan were studied for 2011-2015, with a focus on age and sex, as well as tumor location. Methods: Statistics for total morbidity, primary disability and mortality from cancer in the adult population of the city of Uralsk for 2011-2015 were calcula...

Ovary is one of the main endocrine glands, also the source of female fertility and at the same time the organ with the largest number of histological varieties of malignant tumors. The most frequent among primary neoplasms are epithelial tumors. Secondary tumors of the ovary arise by direct tumor extension from adjacent organs or tissues, by transtubal or transperitoneal route, as well as hemat...

The results of an extension of follow up (1976 to 1989) of a cohort of workers employed for at least one year between 1 January 1950 and 31 December 1975 at eight oil refineries in Britain are reported. Over 99% of the workers were successfully traced to determine their vital status at 31 December 1989. The mortality observed was compared with that expected from the death rates of all the male ...
