OBJECTIVE To determine whether receptor status and HER-2/neu status remains same in primary and metastatic breast carcinoma to corresponding lymph nodes of individual patients. METHODS Estrogen receptors, progesterone receptors and HER-2/neu immunohistochemical stains were performed on primary and metastatic breast carcinoma to axillary lymph nodes in 100 patients. Data was collected on a Per...

BACKGROUND We investigated the reliability of core needle biopsy (CNB) in evaluating the status of hormone receptor (HR), human epidermal growth factor receptor (HER)-2, and Ki-67 status, and the effect of neoadjuvant chemotherapy (NAC) on the expression of these immunohistochemical markers. METHODS Among 177 patients with breast adenocarcinoma, 95 patients underwent NAC and the remaining 82 ...

BACKGROUND Mammographic density is a potentially modifiable risk factor for breast cancer. To what extent mammographic density is a predictor for both hormone receptor-positive and hormone receptor-negative tumors is unclear. Even less is known about whether mammographic density predicts subtypes of breast cancer defined by expression status of the three receptors: estrogen receptor (ER), proge...

gastric adenocarcinoma is the second leading cause of death due to cancer in the world and in advanced stages the prognosis is poor with current therapies. over-expression of her-2/neu has been seen in several cancers such as gastric cancer and its expression is associated with poor prognosis. the aim of this study is to evaluate the over-expression of her-2/neu in gastric biopsy samples of pat...
