OBJECTIVE Infertility due to anticancer treatments is a major source of distress for young patients with cancer. A survey was performed among breast cancer patients younger than 35 years, to evaluate the acceptance of chemotherapy in the context of infertility risk. METHODS After obtaining written informed consent, we asked 400 premenopausal, early stage(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. Archival material of diagnostic(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)
The aim of this study was to determine the relationship between amplification of HER2 (Human epidermal growth factor receptor 2) and Topo2a (topoisomerase 2a) and their influence on prognosis in metastatic breast cancer (MBC) patients. Amplification of both HER2 and Topo2a genes was determined by chromogenic in situ hybridization (CISH) in primary tumor(More)
In tumors in which estrogen receptor (ER) and growth factor signaling pathways are simultaneously active, there is a bidirectional cross-talk that results in a positive feedback cycle of cell survival and proliferation stimuli. Beside the postulated inverse correlation between ER and �ER2 (human epidermal growth factor receptor 2) as a consequence of(More)
