Evaluation of isolated tumour cells in bone marrow (BM) and peripheral blood has become a major focus of translational cancer research. The presence of disseminated tumour cells in BM is a common phenomenon observed in 30-40% of primary breast cancer patients and independently predicts reduced clinical outcome. The detection of circulating tumour cells(More)
Tumour size in breast cancer influences therapeutic decisions. The purpose of this study was to evaluate sizing of primary breast cancer using mammography, sonography and magnetic resonance imaging (MRI) and thereby establish which imaging method most accurately corresponds with the size of the histological result. Data from 121 patients with primary breast(More)
To prospectively assess circulating tumor cell (CTC) status at baseline (CTCBL) and after one cycle of a new line of systemic therapy (CTC1C), and changes from CTCBL to CTC1C (CTC kinetics, CTCKIN) for their utility in predicting response, progression-free (PFS) and overall survival (OS) in metastatic breast cancer (MBC). CTCBL and CTC1C status was(More)
In metastatic breast cancer (MBC), antigen profiles of metastatic tissue and primary tumor differ in up to 20 % of patients. Reassessment of predictive markers, including human epidermal growth factor receptor 2 (HER2) expression, might help to optimize MBC treatment. While tissue sampling is invasive and often difficult to repeat, circulating tumor cell(More)
BACKGROUND The internet portal http://www.brustkrebs-studien.de (BKS) was launched in 2000 by the German Society of Senology (DGS) and the Baden-Württemberg Institute for Women's Health (IFG) to provide expert-written information on breast cancer online and to encourage and facilitate the participation of breast cancer patients in clinical trials. We(More)
OBJECTIVE Detection of disseminated tumor cells (DTCs) in the bone marrow (BM) of patients with breast cancer is associated with poor outcomes. Recent studies demonstrated that DTCs may serve as a prognostic factor in ovarian cancer. The aim of this 3-center study was to evaluate the impact of BM status on survival in a large cohort of patients with ovarian(More)
BACKGROUND Disseminated tumor cells (DTCs) are detectable in the bone marrow (BM) of patients with primary breast cancer (PBC) and predictive of an impaired prognosis. This large trial aimed to analyze the impact of DTC detection on locoregional relapse (LR). PATIENTS AND METHODS Patients with nonmetastatic PBC were eligible for this analysis. BM(More)
PURPOSE To elucidate the influence of ionizing radiation (IR) on the oncolytic activity of Parvovirus H-1 (H-1PV) in human high-grade glioma cells. METHODS Short term cultures of human high-grade gliomas were irradiated at different doses and infected with H-1PV. Cell viability was assessed by determining relative numbers of surviving cells. Replication(More)
PURPOSE Disseminated tumor cells (DTCs) from bone marrow (BM) are a surrogate of minimal residual disease (MRD) in primary breast cancer (PBC) patients and associated with an adverse prognosis. However, BM sampling is an invasive procedure. Although there is growing evidence that circulating tumor cells (CTCs) from the blood are also suitable for monitoring(More)
Neoadjuvant systemic therapy of primary breast cancer (PBC) patients offers the possibility to monitor treatment response. However, patients might have metastatic relapse despite achieving a pathologic complete response (pCR). This indicates that local response to therapy must not be representative for systemic treatment efficacy. Therefore, the aim of this(More)
