There is a great need to detect gastrointestinal tract cancer at an early stage. It is well known that most carcinoma tissues of the gastrointestinal tract contain carcinoembryonic antigen (CEA). Stools are a rich source of cells derived from the gastrointestinal tract. We analyzed total fecal CEA in 60 gastrointestinal tract cancer patients, 20 benign gastrointestinal tract disorder patients, ...

CONTEXT Pancreatic cancer is often complicated with upper gastrointestinal lesions. However, there have been few endoscopic studies in pancreatic cancer patients. We retrospectively investigated the upper gastrointestinal lesions in patients with pancreatic cancer who underwent upper gastrointestinal endoscopy. METHODS Upper gastrointestinal endoscopy was performed in 75 patients with pancrea...

peutz–jeghers syndrome is a rare condition characterized by mucocutaneous pigmentation, polyposis and an increased cancer risk at a number of gastrointestinal and extra intestinal organs. we present a patient with a history of gastrointestinal bleeding with no mucocutaneous pigmentation. upper and lower gastrointestinal endoscopy revealed multiple polyps located in the deuodenum and colon. hist...

This meta-analysis aimed to provide an up-to-date comprehensive evaluation on the association between the MDM2 40bp indel polymorphism and cancer susceptibility. Eligible studies were retrieved by searching Web of Science, PubMed, Scopus, and Google scholar databases up to August 27, 2018. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the ...

the gastrointestinal stromal tumor (gist) is a rare mesenchymal tumor of gastrointestinal (gi) tract. this tumor has tendency to liver metastasis and peritoneal recurrence, however; the primarily lymph node involvement or metastasis is rare. here we reported a 17-years-old girl with multifocal gastric gist and multiple lymph node involvement at presentation and recurrence in celiac lymph nodes....

Purpose: The chemokine receptors CCR7 and CXCR4 have been shown to play an important role in cancer invasion and metastasis. This study was aimed to investigate CCR7 and CXCR4 expressions and evaluate the association between their expressions and the clinicopathological features in gastrointestinal cancer. Method: 27 paired tissue samples from patients who had curative surgery for gastrointesti...

Sirtuin 1 (SIRT1), a well-characterized NAD+-dependent histone deacetylase, is generally up-regulated in gastrointestinal cancers. However, the prognostic value of SIRT1 in gastrointestinal cancer remains inconclusive. Therefore, we report a meta-analysis of the association of SIRT1 expression with overall survival (OS) in gastrointestinal cancer. PubMed was systematically searched for studies ...
