Background: Adenocarcinoma of the prostate is an invasive carcinoma, a neoplasm epithelial cells with secretory cell differentiation. Histomorphology glandular. The are sheets or single neoplasia, basal not seen in this carcinoma. Tumor-Infiltrating Lymphocytes (TILs) lymphocytes that migrate to tumor peritumoral cells. In malignancy, T lymphocyte infiltration can be found, indicating immune re...
cancer stem cells (cscs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. recently the role of some of cscs in gastric adenocarcinoma has been studied. this study was performed in order to evaluate cd44 and cd133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological paramete...
Alpha-fetoprotein (AFP) producing gastric adenocarcinoma is considered as a rare subtype of gastric adenocarcinoma. Compared with AFP non-producing gastric adenocarcinoma, our study and other previous studies showed that AFP producing gastric adenocarcinoma is more aggressive and prone to liver metastasis. Using the Protein Pathway Array, 11 of out of 286 proteins tested were found to be differ...
nasal sinuses representing about 70% of malignant tumors. Only between 10% and 20% correspond to adenocarcinomas mostly originated in the minor submucous glands. Less frequent tumors originate in the cavity lining epithelium, such as intestinal-type adenocarcinoma (ITA) and low-grade adenocarcinoma (LGA). The ITA, described by Jarvi in 1945 1 , is also known as mucinous adenocarcinoma, colon ad...
Background & Aims: Solid tumors in their course of development have the stages of dysplasia, carcinoma insitu, angiogenesis, invasion and metastasis. In this process, peptide components having the ability of angiogenesis inhibition (angiostatin) are produced and due to their low molecular weight, they are filtrated. The purpose of this study is to study the probability of primary diagnosis of ...
Background& Aims: Gastric adenocarcinoma has been considered as an infectious disease since 1994, when the Helicobacter pylori (H. pylori) infection categorized as a definite class I human carcinogen. H. pylori uses extensive numbers of virulence factors to overcome host defence mechanisms. One independent H. pylori factor that plays an important role in determining H.pylori pathogenesisis vacu...
1.3.1. Histopathologic types (according to World Health Organization/ International Society of Gynecological Pathology classification) All tumors are to be microscopically verified. The histopathologic types are: • Endometrioid carcinoma: adenocarcinoma; adenoacanthoma (adenocarcinoma with squamous metaplasia); and adenosquamous carcinoma (mixed adenocarcinoma and squamous cell carcinoma). • Mu...
Anal malignancies constitute approximately 1 to 3 % of all large-bowel carcinomas 1, 2 and less than 6 % of all anorectal carcinomas 3,4 . The latter is either squamous or glandular type. The squamous cell carcinoma is much more common than adenocarcinoma. Anal canal adenocarcinoma is subclassified into adenocarcinoma arising in anal mucosa and extamucosal (perianal) adenocarcinoma. The latter ...
Activating mutations in Epidermal growth factor receptor (EGFR) occur approximately 15% White, 40-50% of Asian and Black patients with lung adenocarcinoma. However, its prevalence the nearly 60 million U.S. Hispanics has not been well characterized. Herein we evaluate EGFR mutation frequency Hispanic adenocarcinoma at an academic institute serving a large multi-ethnic area.
background barrett’s oesophagus is a pre-malignant condition at gastroesophageal junction in which normal squamous epithelium is replaced by columnar shape epithelium, which predisposes oesophageal adenocarcinoma. it is known that barrett’s oesophagus evolves as a consequence of chronic gastro-oesophageal reflux disease. although progression of barrett’s oesophagus to adenocarcinoma is still un...
