Breast Carcinoma; Human Epidermal Growth Factor Receptor-2 (HER-2) and Grading Correlation
Introduction: Overexpression of Human Epidermal Growth factor Receptor-2 (HER-2) is one of the most important prognostic and predictive factors of breast cancer, observed in 25% - 30% of breast carcinoma patients leading to poor prognosis and feasible anti HER-2 antibody drugs. The objective of this study was to evaluate the HER-2 frequency in target population and its correlat...
متن کاملEpidermal growth factor in breast cyst fluid: relationship with intracystic cation and androgen conjugate content.
In recent years, several studies focused on the biochemical analysis of breast cyst fluid composition. It has been shown that breast cysts lined by apocrine epithelium contain higher levels of potassium and dehydroepiandrosterone-sulphate as compared to cysts lined by flattened cells, and that women with apocrine cysts are more likely to develop breast cancer. In the present study, we measured ...
متن کاملProteases in cyst fluid from human gross cyst breast disease.
Cyst fluid from women with gross cystic breast disease was found to contain protease activity when assayed against [14C]albumin. At least six different proteases were detected when the fluid was fractionated by a combination of S-300 Sephacel, hydroxylapatite, and DEAE-Sephacel chromatographic techniques. The distribution of the proteases appeared to be related to the ionic composition of the f...
متن کاملImaging features of estrogen-negative breast cancers: a correlation study with human epidermal growth factor type II overexpression
Background: Estrogen-negative breast cancers have different clinical course, prognostic features and treatment response in comparison to estrogen receptor-positive (ER-positive) breast cancers. Human epidermal growth factor receptor 2 (HER2) oncoprotein has found to have a pivotal role in natural cell growth and cell division and is suggested to be directly related to tumor invasiveness in brea...
متن کاملEpidermal Growth Factor Receptors and Breast Cancer
Growth factors are polypeptides that stimulate cell proliferation through binding to specific high-affinity cell membrane receptors. Plasma contains small quantities of growth factors. Platelets contain large amounts and it is thought that these are delivered to sites of injury where they may influence wound healing and repair. Growth factors are present in a variety of other tissues and have d...
