Provista Diagnostics Announces Enhanced Breast Cancer Detection Using a Simple Blood Test in New Peer-Reviewed Publication


SCOTTSDALE, Ariz.,  /PRNewswire/ -- Provista Diagnostics today announced the results of its latest clinical study of its simple blood test to further validate its proteomic biomarker assay, Videssa®. The article titled "A Non-Invasive Blood-Based Combinatorial Proteomic Biomarker Assay to Detect Breast Cancer in Women over age 50 with BI-RADS 3, 4, or 5 Assessment," was published in Clinical Cancer Research and is available at

The study concluded that Videssa when used in conjunction with breast imaging improved breast cancer detection compared to mammography alone in women with moderate risk of malignancy. When combined with ProvistaDX's previously published data for women under age 50, Videssa achieves a comprehensive 93% sensitivity and 98% NPV in a population of women ages 25 - 75. Had Videssa results been incorporated into the clinical workflow, approximately 45% of biopsies might have been avoided.

This simple blood test is for the early detection of active breast cancer irrespective of breast density. "Videssa has again demonstrated it's a reliable and accurate method of detecting breast cancer when used in combination with mammography", said Gary Altman, CEO.

Performance of Videssa® from two prospective trials that enrolled 1,350 women, ages 25-75, with abnormal or difficult-to-interpret imaging (BI-RADS 3, 4 and 5) was evaluated. The study combined biomarker data with patient clinical data to develop a training cohort (469 women, cancer incidence: 18.5%), resulting in 94% sensitivity and 97% negative predictive value (NPV). Independent validation of the final algorithm in 194 subjects (BC incidence: 19.6%) demonstrated a sensitivity of 95% and a NPV of 97%.
