The Fifth edition of the World Health Organization classification digestive system and American Joint Committee on Cancer staging manual contain substantial refinements information for esophageal tumors. epithelial tumors esophagus are classified as benign, dysplasia, malignant groups. Dysplasia is divided into Barrett dysplasia squamous graded either low-grade or high-grade. Malignant often ad...

objective: the purpose of this pilot study was to determine whether the mri and biomarkers human epididymis protein 4 (he 4 ) and ca 125 correlate with depth of myometrial invasion, histologic grade, cervical involvement and nodal metastases in patients with endometrioid adenocarcinoma of the uterus. materials and methods: this was a prospective, observational study in women with biopsy-proven ...

The progression of Barrett's esophagus to esophageal adenocarcinoma is often characterized by the accumulation of genetic abnormalities. The goal was to evaluate the copy number alterations of several oncogene loci, including 7p12 [epidermal growth factor receptor (EGFR)], 8q24 (c-myc), and 20q13 in the sequence of no dysplasia-dysplasia-adenocarcinoma of Barrett's esophagus. Fluorescence in si...

Barrett's esophagus predisposes affected patients to the development of esophageal adenocarcinoma. The development of adenocarcinoma proceeds along a progression through low- and high-grade dysplasia. Surveillance of Barrett's patients requires serial endoscopic investigations and grading mucosal biopsies. Unfortunately, grading of biopsies by conventional hematoxylin and eosin staining is frau...

prostatic intra-epithelial neoplasia (pin) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. in this study, we applied the pin grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of pro...

BACKGROUND/AIMS Insulin-like growth factor II mRNA-binding protein 3 (IMP3) is an oncofetal protein with vital function during human embryogenesis in terms of cellular growth and migration. Although it has minimum and undetectable expression in human adult tissues, it is highly expressed in various types of cancer. Few studies have recommend application of IMP3 expression to diagnose challengin...

PURPOSE Esophageal adenocarcinoma is a highly aggressive malignancy that frequently develops from Barrett's esophagus, a premalignant pathologic change occurring in the lower end of the esophagus. Identifying Barrett's esophagus patients at high risk of malignant transformation is essential to the prevention of esophageal adenocarcinoma. Although microRNA (miRNA) expression signatures have been...
