“…Some studies have indicated that LGD and HGD should be treated, because genomic instability may already be present [49][50][51][52]. However, the European guidelines recommend reassessment with biopsy sampling and surveillance at 6-month to 1-year intervals for patients with HGD in the absence of endoscopically defined lesions [8]. According to whether there is evidence of invasion, there is a potential risk of underdiagnosing a lesion as LGD or HGD, even if it is submucosal or advanced GC.…”

“…There are no universally accepted criteria for invasive growth into the lamina propria [16]. Therefore, histological findings of invasion are defined according to the World Health Organization (WHO) classification and European management guidelines as follows: invasion into the muscularis mucosa or submucosa; lymphovascular invasion; infiltration of the stroma by single cells; small clusters of cells (small nest); small gland formation, and marked glandular crowding; excessive branching, budding, and a trabecular pattern; fused glands, cribriform glands; stromal response (desmoplasia) [6,8]. For objective evaluation of invasion in this study, the Vienna Classification was used (Table 1) [9].…”

Comparative study of Western and Japanese criteria for biopsy-based diagnosis of gastric epithelial neoplasia

et al. 2014

Background In Western countries, gastric cancer (GC) is diagnosed when there is histological evidence of invasion into the lamina propria or beyond the submucosa. In Japan and some other countries, however, diagnosis of GC is based on the degree of structural and cytological abnormality of tumor glands. The aim of the present study was to compare the accuracy of the Western and Japanese criteria for diagnosis of GC. Methods The study included 233 consecutive patients with a postoperative diagnosis of submucosal invasive GC who underwent gastrectomy or endoscopic submucosal dissection. All pretreatment biopsy specimens were independently reviewed by two experts in gastrointestinal pathology employing both the Western and Japanese diagnostic criteria. Diagnostic agreement between pretreatment biopsy specimens and the corresponding resected specimens was evaluated, together with the interobserver agreement for each of the criteria. Results On the basis of the Western and Japanese criteria, the pretreatment biopsy diagnosis was noncancerous (including dysplasia) in 44 lesions and 1 lesion, respectively. Diagnostic accuracy based on biopsy was 81.1 % for the Western criteria and 99.5 % for the Japanese criteria (P \ 0.001). Interobserver agreement based on the Western and Japanese criteria was 73.8 % and 96.5 %, respectively (P \ 0.001). Invasion into the submucosa was detected by biopsy in only 25 cases. Conclusions The Japanese criteria are significantly more accurate for pretreatment biopsy diagnosis of GC. The Western criteria could lead to underdiagnosis of a lesion as high-grade dysplasia, even if submucosal invasive cancer is present.

Hintergrund Vorläuferläsionen des sporadischen MagenkarzinomsIm Gegensatz zum kolorektalen Karzinom, welches nahezu immer aus einer adenomatösen Vorläuferläsion entsteht [14], entwickelt sich das sporadische Magenkarzinom, speziell der intestinale Typ (nach Laurén), in der Regel auf dem Boden einer chronischen Gastritis und nur vergleichsweise selten im Rahmen einer Adenom-Karzinom-Sequenz. Daher sollte der histopathologische Nachweis einer intraepithelialen Neoplasie im Magen stets zunächst an die Möglichkeit einer gastritisassoziierten Dysplasie denken lassen, da diese weitaus häufiger ist als ein Adenom. Die moderne endoskopische Bildgebung erleichtert zunehmend die Detektion der häufig nicht polypösen, d. h flachen dysplastischen Krebsvorstufen [2,3].

Over last three decades, tremendous progress has been made to understand its biology [8][9][10], epidemiology [11][12], pathogenicity [13], treatment [14][15][16][17][18], and laboratory diagnosis [19][20][21][22].

Helicobacter pylori is a micro-aerophilic, slow-growing, Gram-negative spiral bacterium that colonizes the mucous lining of the human stomach. Infection with this bacterium has been identified as a cause of gastritis, peptic ulcer disease, and gastric mucosa-associated lymphoid tissue lymphoma. Globally, the prevalence of H. pylori-related infection is high compared to any other infectious diseases, and the rate of prevalence much higher in developing countries than in developed nations. This review article aims to describe the trend of H. pylori-related works in the Kingdom of Saudi Arabia (KSA) and the use of various laboratory tests for the diagnosis of H. pylori-related infections in adults and children. Therefore, published literature was referenced in the explanation and discussion of the different methods used to diagnose H. pylori-related disease, including papers published in the KSA and other Middle Eastern countries. The PubMed (http://www.ncbi.nlm.nih.gov/pubmed?cmd=search) search engine was used extensively. Culture and histopathology tests have been employed widely to detect this pathogen at the early stage. However, over the years, an array of tests including the rapid urease test, serology, the urea breath test, the fecal antigen test, and molecular testing have been developed to diagnose and better manage H. pylori-associated diseases since the discovery of this novel pathogen.
