BACKGROUND The detection of cytokeratin-19 (CK-19) mRNA-positive circulating tumor cells (CTC) before and/or after adjuvant chemotherapy in patients with operable breast cancer is associated with poor clinical outcome. Reliable prognostic markers for late disease relapse are not available. In this study we investigated the value of CTC detection during the(More)
BACKGROUND To compare detection rates and evaluate the clinical relevance of cytokeratin-19 (CK-19) mRNA-positive cells in the peripheral blood (circulating tumour cells, CTCs) and bone marrow (disseminated tumour cells; DTCs) of patients with early breast cancer. METHODS Paired samples of peripheral blood and bone marrow were obtained from 165 patients(More)
BACKGROUND The purpose of this study was to evaluate the prognostic significance of the molecular detection of cytokeratin 19 (CK-19) mRNA-positive cells in the peripheral blood of women with operable breast cancer after the completion of adjuvant chemotherapy. PATIENTS AND METHODS Blood from 161 patients with stage I and II breast cancer, obtained after(More)
BACKGROUND To investigate the clinical relevance of CK-19mRNA-positive circulating tumour cells (CTCs) detected before the initiation of front-line treatment in patients with metastatic breast cancer (MBC). METHODS The presence of CTCs was detected in 298 patients with MBC using a real-time PCR (RT-PCR assay. In 44 patients, the detection of CTCs was(More)
10554 Background: To investigate the effect of adjuvant taxane-free and taxane-based chemotherapy regimens on the elimination of circulating tumor cells (CTCs) in patients with early breast cancer. METHODS The presence of CK-19 mRNA-positive CTCs in the peripheral blood was evaluated both before and after chemotherapy, using a real-time RT-PCR assay, in(More)
INTRODUCTION To evaluate the incidence of central nervous system (CNS) involvement in patients with breast cancer treated with a taxane-based chemotherapy regimen and to determine predictive factors for CNS relapse. METHODS The medical files of patients with early breast cancer (n = 253) or advanced stage breast cancer (n = 239) as well of those with(More)
