The 7th edition of Union for International Cancer Control (UICC) staging system moved gastroesophageal junction (GEJ) cancers from gastric to esophageal group. Since clinical management is strongly influenced by this staging system, we looked at molecular fingerprints of GEJ tumors and compared to gastric and esophageal profiles. We aimed at elucidating whether GEJ cancers cluster with gastric ...

Gastric cancer remains one of the deadly diseases with poor prognosis. New classification of gastric cancers based on histologic features, genotypes and molecular phenotypes helps better understand the characteristics of each subtype, and improve early diagnosis, prevention and treatment. The objective of this article is to review the new classification of gastric cancers and the up-to-date gui...

Background: Population based research contributes to our understanding of cancer at many levels. For health program planning and policy making it is important to have information about the incidence of the common cancers in the population. Descriptive epidemiologic studies measure the occurrence of cancer and other health-related factors in relation to person (e.g. age, sex, race, social class,...

BACKGROUND DEK, as an oncoprotein, plays an important role in cancer development and progression. This study aimed to investigate the clinicopathological significance of DEK overexpression in patients with gastric cancer. MATERIALS AND METHODS The expression of DEK protein was evaluated by immunohistochemical (IHC) staining of 172 gastric cancer samples with complete clinicopathological featu...

Animal models have greatly enriched our understanding of the molecular mechanisms of numerous types of cancers. Gastric cancer is one of the most common cancers worldwide, with a poor prognosis and high incidence of drug-resistance. However, most inbred strains of mice have proven resistant to gastric carcinogenesis. To establish useful models which mimic human gastric cancer phenotypes, invest...

Cancers evolve as a result of the accelerated proliferation cancer cells in complicated, enriched, and active microenvironment. Tumor microenvironment (TME) components are master regulators any step development. The tumor is composed many cellular noncellular that contribute to evolution cells. Cancer-associated fibroblasts (CAFs) activated TME implicate progression metastasis dissemination thr...

Gastric cancers arise through a multistep process characterized by the progressive accumulation of molecular alterations in which genetic and epigenetic mechanisms have been implicated. Gastric cancer is one of the human malignancies in which aberrant promoter CpG island hypermethylation is frequently found. Helicobacter pylori and Epstein-Barr virus, which are known carcinogens for gastric can...

BACKGROUND AND STUDY AIMS To suggest an appropriate surveillance strategy after curative endoscopic submucosal dissection (ESD) for early gastric cancers, based on incidence and patterns of local, metachronous, and extragastric recurrence. PATIENTS AND METHODS Between 2003 and 2011, 1497 consecutive patients with 1539 differentiated-type early gastric cancers meeting absolute or expanded indi...

ATP-binding cassette (ABC) transporters are involved in chemotherapy resistance. Multidrug-resistance protein 8 (ABCC11/MRP8) is also involved in 5-fluorouracil (5-FU) metabolism. 5-FU and its derivatives are widely used in the treatment of gastrointestinal tract cancers, but little is known about the contribution of ABCC11/MRP8 to gastrointestinal tract and related cancers. Here, we report our...
