Provista 002 prospective randomized trial utilizing Videssa in conjunction with imaging to detect breast cancer from patients with imaging findings age 25-75.

31 Background: An approach to detection that relies on biochemical markers of breast cancer would significantly contribute to more accurate detection in women with suspicious lesions. The combination of imaging, which identifies anatomical anomalies consistent with cancer with proteomic approaches promises to provide a powerful detection paradigm. A proteomic detection approach would provide a powerful tool for the detection of breast cancer in women with dense breast, a diagnosis that is difficult utilizing imaging alone. While protein signatures for the presence of breast cancer have remained elusive, we have developed a novel approach that combines serum protein biomarkers with tumor-associated autoantibodies. We utilized prospectively collected serum samples to develop novel algorithms for use in conjunction with imaging. We tested whether the assay was able to distinguish benign from invasive breast cancers in a prospective, randomized setting. Methods: Provista-002 enrolled 509 patients from multipl...
