Serous adenocarcinoma of the endocervix is a rare carcinoma similar to the serous carcinoma of the ovary and the endometrium. We report a case of a 63-year-old woman with papillary serous adenocarcinoma arising within the endocervix, describing the clinical...

Gallbladder carcinoma: the role of p53 protein overexpression and Ki-67 antigen expression as prognostic markers.

HPB : the official journal of the International Hepato Pancreato Biliary Association

Hidalgo Grau LA, Badia JM, Salvador CA, Monsó TS, Canaleta JF, Nogués JM, Sala JS.
PMID: 18333072
HPB (Oxford). 2004;6(3):174-80. doi: 10.1080/13651820410025110.

BACKGROUND: The overexpression of p53 protein and the expression of Ki-67 antigen may affect the survival of patients with gallbladder carcinoma. This association has been tested in a series of 41 patients with relatively early carcinoma of the gallbladder.METHODS:...

Comparison of 4 proliferation markers and their significance for evaluation of tumor dignity in intracranial tumors.

International journal of oncology

Hagel C, Schwartz P, Laas R, Stavrou D.
PMID: 21552814
Int J Oncol. 1995 Jul;7(1):107-13. doi: 10.3892/ijo.7.1.107.

The proliferation indices of immunohistochemically detected bromodeoxyuridine, Ki-67 antigen (antibodies Ki-67 and MIB 1), and proliferating cell nuclear antigen were determined manually and with computer assisted morphometry in 38 gliomas, 29 meningeomas, 9 metastases, and 16 other tumors. Comparing...

Expression of her-2/neu oncogene in breast-cancer - correlation of quantitative immunocytochemistry and prognostic factors.

International journal of oncology

Charpin C, Devictor B, Bonnier P, Andrac L, Lavaut M, Allasia C, Piana L.
PMID: 21584622
Int J Oncol. 1992 Dec;1(7):815-23.

HER-2/neu oncogene expression by breast carcinomas (n = 208) was investigated on frozen sections using monoclonal anti-p185 HER-2/neu protein. Results were evaluated by computer-assisted image analysis and correlated with morphological prognostic factors, hormone receptor antigenic sites, Ki 67 antigen...

PURPOSE: Several studies have shown that estrogen receptor (ER) and progesterone receptor (PR) expression and human epidermal growth factor receptor 2 (HER2) expression may vary during tumoral progression. We aimed to describe and compare ER, PR, and HER2 expressions...

Malignancy course of pituitary adenoma in MEN1 syndrome: Clinical-Neuroradiological signs.
