Background Ten patients with breast cancer and a breast cancer susceptibility gene 1 (BRCA1) mutation, who presented with stages I to III breast cancer between December 2006 and 2007, were treated with four cycles of neoadjuvant cisplatin, followed by mastectomy and conventional chemotherapy. Methods The excised breast tissue and lymph nodes were examined(More)
Background:To investigate whether copy number gain of MET or hepatocyte growth factor (HGF) affect trastuzumab sensitivity in HER2-positive metastatic breast cancer (MBC).Methods:We analysed 130 HER2-positive MBC treated with trastuzumab-based therapy. MET and HGF gene copy numbers (GCN) were assessed by fluorescence in situ hybridisation (FISH) in primary(More)
UNLABELLED Molecular mechanisms of lapatinib resistance in breast cancer are not well understood. The aim of this study was to correlate expression of selected proteins involved in ErbB family signaling pathways with clinical efficacy of lapatinib. Study group included 270 HER2-positive advanced breast cancer patients treated with lapatinib and(More)
Material and methods Between December 2006 and August 2011 seventy five women with BRCA1 mutation and diagnosed with breast cancer stage I to III were enrolled. Patients were treated with Cisplatin at dose 75 mg/m2 every three weeks for four cycles. After chemotherapy mastectomy was performed and followed with conventional chemotherapy. Seven patients had(More)
PURPOSE P95HER2 (p95) is a truncated form of the HER2, which lacks the trastuzumab-binding site and contains a hyperactive kinase domain. Previously, an optimal clinical cutoff of p95 expression for progression-free survival (PFS) and overall survival (OS) was defined using a quantitative VeraTag assay (Monogram Biosciences) in a training set of(More)

Patients and methods 50 women with breast cancer and a BRCA1 mutation, who presented with stage I to III breast cancer between December 2006 and April 2010 were enrolled and treated with cisplatin 75 mg/m every three weeks for four cycles, followed by mastectomy and conventional chemotherapy. Eight patients had prior chemotherapy for a previous cancer(More)

502 Background: Neoadjuvant chemotherapy is administered to control disease, make surgical resection possible and increase the possibility of breast tissue conservation. A further advantage of neoadjuvant therapy is that it helps to assess chemo-sensitivity to a particular agent. Induction of a pathological complete response (pCR) is one of the primary(More)
BACKGROUND The knowledge of the epidemiology of left ventricular systolic dysfunction (LVSD) in relationship with cardiovascular diseases, their risk factors and history of previous anticancer therapy may lead to development of safer and more effective therapeutic strategies in patients with breast cancer (BC).
