C-erb-B-2 oncoprotein and epidermal growth factor receptor in human hepatocellular carcinoma: an immunohistochemical study.
The aim of this study was to evaluate the immunohistochemical expression of epidermal growth factor (EGFR) and c-erb-B-2 oncoprotein in a series of 71 hepatocellular carcinomas as well as in the adjacent hepatic tissue and to assess any correlation with HBsAg expression. The total of the 71 hepatocellular carcinomas (HCCs) was classified into 17 low grade and 54 high grade cases with adjacent n...
متن کاملSignificance of erb-B2 immunoreactivity in cervical cancer.
C-erbB2 is over-expressed or amplified in many carcinomas. We assessed the relationship between erb-B2 immunoreactivity, and its predictive role in progression-free survival and treatment outcome in patients with cervical carcinoma. Sections from 65 cervical carcinoma were immunostained with antibody to p185 erbB2. Immunoreactive ErbB2 was found in 25 patients (38%) [+ 15 pts. (23%); ++ 10 pts....
متن کاملPrognostic value of amplification of c-erb-B2 in bladder carcinoma.
Amplification of c-erb-B2 is examined in patients with transitional cell bladder carcinoma. In a pilot study we found that the amplification correlated with high tumor grade. Tumor grade is a known prognostic factor. Therefore, we next examined the prognostic value of c-erb-B2 amplification in patients with >16 years of clinical follow-up. The gene copy number was determined, using semiquantita...
متن کامل[The relationship between p53 protein and c-erb B-2 expression and apoptosis in colorectal cancer].
In order to elucidate the relationship between tumor growth and various kinds of gene expression and the occurrence of apoptosis in the front portion of neoplastic invasion, 57 advanced colorectal cancers were studied by immunohistochemical staining of p53, c-erb B-2, the TUNEL method and electron microscopy. Light microscopically, the columnar epithelial cells of adenocarcinoma frequently show...
متن کاملThe Predictive and Prognostic Significance of c-erb-B2, EGFR, PTEN, mTOR, PI3K, p27, and ERCC1 Expression in Hepatocellular Carcinoma
BACKGROUND Hepatocellular carcinoma (HCC) is the fifth most common fatal cancer and an important healthcare problem worldwide. There are many studies describing the prognostic and predictive effects of epidermal growth factor receptor 2 (c-erb-B2) and epidermal growth factor receptor 1 (EGFR), transmembrane tyrosine kinases that influence cell growth and proliferation in many tumors. OBJECTIV...
