Abstract Purpose: The CellSearch system (Veridex, Warren, NJ) is designed to enrich and enumerate circulating tumor cells (CTCs) from peripheral blood. Here, we validated the analytic performance of this for clinical use in patients with metastatic breast cancer. Experimental Design: This prospective multicenter study conducted at three independent laboratories involved samples 92 Intra- inter-assay variability using controls containing defined numbers (average, 50 1,000, respectively), cell...

Purpose Recent advances in DNA sequencing have led to the development of breast cancer susceptibility gene panels for germline genetic testing patients. We assessed frequency mutations 17 predisposition genes, including BRCA1 and BRCA2, a large cohort patients with triple-negative (TNBC) unselected family history or ovarian determine utility those TNBC. Patients Methods TNBC (N = 1,824) were recruited through 12 studies, was sequenced identify mutations. Results Deleterious identified 14.6%...

Abstract Introduction MicroRNAs (miRs) are interesting new diagnostic targets that may provide important insights into the molecular pathogenesis of breast cancer. Here we evaluated, for first time, feasibility and clinical utility circulating miRs as biomarkers detection staging Methods The relative concentrations cancer-associated miR10b, miR34a, miR141 miR155 were measured in blood serum 89 patients with primary cancer (M0, n = 59) metastatic disease (M1, 30), 29 healthy women by a TaqMan...

The prognostic significance of disseminated tumor cells (DTC) in bone marrow (BM) breast cancer patients at the time primary diagnosis has been confirmed by a large pooled analysis. In view lack early indicators for secondary adjuvant treatment, we here evaluated whether persistence DTCs after therapy increases risk subsequent relapse and death.Individual patient data from 676 women with stages I-III 3 follow-up studies were pooled. During clinical follow-up, underwent BM aspiration (BMA) to...

Abstract Background The phenotypes of tumor cells change during disease progression, but invasive rebiopsies metastatic lesions are not always feasible. Here we aimed to determine whether initially HER2-negative breast cancer (MBC) patients with HER2-positive circulating (CTCs) benefit from a HER2-targeted therapy. Methods open-label, interventional randomized phase III clinical trial (EudraCT Number 2010-024238-46, CliniclTrials.gov Identifier: NCT01619111) recruited March 2012 until...

Abstract Purpose: Ertumaxomab is an intact bispecific antibody targeting HER2/neu and CD3 with selective binding to activatory Fcγ type I/III receptors, resulting in the formation of a tri-cell complex between tumor cells, T accessory cells. Patients metastatic breast cancer were enrolled into multicenter phase I dose-escalating trial. Experimental Design: Three ascending doses ertumaxomab (10-200 μg) administered i.v. on day 1, 7 ± 13 1. Safety tolerability primary objectives. Secondary...

Abstract Introduction There is a multitude of assays for the detection circulating tumor cells (CTCs) but very limited number studies comparing clinical relevance results obtained with different test methods. The DETECT trial metastatic breast cancer patients was designed to directly compare prognostic impact two commercially available CTC that are prominent representatives immunocytochemical and RT-PCR based technologies.

Abstract BACKGROUND The prognostic significance of isolated tumor cells (ITCs) in bone marrow (BM) from patients with breast carcinoma at the time their primary diagnosis recently was been confirmed by a large pooled analysis. If persistence ITCs after adjuvant therapy confers similar risk for recurrence, then it would be an indication to consider secondary therapy. METHODS authors analyzed BM aspirates 228 during recurrence‐free follow‐up median interval ± standard deviation (SD) 21.3 29.1...

Triple-negative (TN) breast cancer is an aggressive subtype of associated with a unique set epidemiologic and genetic risk factors. We conducted two-stage genome-wide association study TN (stage 1: 1529 cases, 3399 controls; stage 2: 2148 1309 controls) to identify loci that influence risk. Variants in the 19p13.1 PTHLH showed significant associations (P < 5 × 10−8) 1 2 combined. Results also suggested substantial enrichment significantly variants among single nucleotide polymorphisms (SNPs)...
