PURPOSE In addition to Estrogen Receptor alpha (ERalpha) and Progesterone Receptor (PR), the Second Estrogen Receptor (ERbeta) appears to play an important role not only in estrogen signaling, but also in the pathogenesis of cancer in estrogen dependent tissues. The existence of various isoforms and splice variants of both ERs additionally complicates(More)
The biological significance of estrogen receptor-negative but progesterone receptor-positive breast carcinomas is not clear. In the present study the aggressiveness of breast carcinomas in relation to ER and PgR status has been investigated. The probability of disease-free survival in 297 node-negative breast carcinoma patients was monitored during a(More)
Epidermal growth factor receptor was determined in 106 newly diagnosed breast cancer patients, using the biochemical method. The group consisted of 58 patients in stage I-II, and 48 patients in stage III-IV. Although a significant inverse correlation was found between EGF-R status, and ER or PR status, quantitative content of EGF-R did not correlate either(More)
The purpose of the study was to asses the expression of estrogen-induced pS2 and cathepsin D (CD) that might facilitate biological subgrouping of patients with breast carcinomas (BC) and its potential applicability in clinical oncology. The study included 226 patients with histologically verified BC. Clinico-pathological findings were classified according(More)
In order to address the heterogeneity of the pT1 breast cancer stages, we have been examining the natural and the clinical course of disease in relation to cathepsin D expression, as a molecular marker for the tumor progression that leads to metastasis. The original aim of our pilot study was to determine whether it was possible to distinguish high-risk(More)
Owing to exceptional heterogeneity in the outcome of invasive breast cancer it is essential to develop highly accurate prognostic tools for effective therapeutic management. Based on this pressing need, we aimed to improve breast cancer prognosis by exploring the prognostic value of tumor histology image analysis. Patient group (n=78) selection was based on(More)
Estrogen and progesterone receptor content was determined in 34 patients with synchronous and 23 patients with asynchronous bilateral breast cancer. Steroid receptor content was measured quantitatively by DCC method. It was shown that progesterone receptor content could not be predicted, as well as, that steroid receptor content of the second tumor(More)
AIM The aim of this study was to evaluate clinical usefulness of cathepsin D status in early breast cancer during the first 3 years of follow-up. PATIENTS & METHODS The study included 226 patients with histologically verified, primary operable invasive early breast carcinomas. Concentrations of estrogen receptor (ER) and progesterone receptor (PR) in(More)
BACKGROUND A role of an estrogen-regulated, autocrine motogenic factor was assumed to be a major biological role of trefoil factor 1 (TFF1) in breast cancer. TFF1 is regarded as a predictive factor for positive response to endocrine therapy in breast cancer patients. The aim of our study was to examine TFF1 level distribution in breast carcinomas in order(More)
Objectives were to evaluate the relevance of proliferating fraction (Ki-67) along with apoptotic index (AI) which denoted growth index (Ki-67/AI ratio, GI) to predict pathological response to preoperative chemotherapy, and the pattern of their modifications following chemotherapy in women with locally advanced breast cancer.
