Annexin A3 (ANXA3) as Protein-Based Marker for Non-Invasive Molecular Diagnostics of Prostate Carcinoma


The aim of this multi centre and double-blinded study was to investigate specificities and
sensitivities of early detection of prostate cancer with a new protein biomarker, annexin
A3, using urine after digital rectal examination/massage (exprimate urine) in direct
comparison to the corresponding measurements of the gold standard, total PSA. The material
obtained by this non-invasive procedure was moreover used to determine appropriate cut-off
values and optimal fractions (e.g. after centrifugation) and calibrations for quantitative
measurements of this novel marker.

Patients (500-750) were (and are) continuously recruited from four clinical centres in
Germany (Berlin, Tübingen, Ludwigshafen) and Austria (Innsbruck). The major aspect was:

• Can annexin A3 provide a better specificity than tPSA, in particular in the grey zone of
PSA (2-10 ng/ml) and can annexin A3 thus contribute to a significant reduction of invasive
transrectal biopsies?
