Scientific titleA comparison of an antibody-based and an RT-PCR-based technique for the detection of circulating epithelial tumour cells: A multicentre, observational study
Study acronymDETECT
Study objectivesThe aim of this prospective multi-centre trial was to compare the HER2 status of circulating tumour cells (CTCs) in 254 metastatic breast cancer patients at the time of first diagnosis or disease progression obtained by the antibody-based CellSearch® assay and the RT-PCR approach AdnaTest™ Breast Cancer and to assess the concordance rate between these two techniques.
Ethics approval(s)The local institutional review board of the University of Tuebingen, Germany approved on the 26th of September 2007 (ref: 2007/B01).
Health condition(s) or problem(s) studiedMetastatic breast cancer
InterventionMetastatic breast cancer patients were enrolled in this prospective open non-randomized and non-interventional study. Blood was drawn before the start of a new line of therapy.
1. Blood sampling mandatory (one or two times 50mL)
2. Bone marrow aspiration (not mandatory)
Intervention typeOther
Primary outcome measure(s)

Rate of HER2 positive CTCs with each method

Key secondary outcome measure(s)

Concordance between the two methods in (HER2 positive) CTC detection
