Study finds more than 40 percent of prostate biopsies could be avoided with new blood test

Friday, May 18, 2018, San Francisco: A multi-center study that validates the clinical performance of IsoPSA – a new blood test that has proven to be more accurate in predicting overall risk of prostate cancer than standard prostate-specific antigen (PSA) – will be presented during a special press conference at the 13th Annual Meeting of the American Urological Association (AUA) on May 18 in San Francisco.

Results showed that more than 40 percent of biopsies could have been avoided in both the preliminary study (45.1 percent) and validation study (47 percent), suggesting that use of IsoPSA may substantially reduce the need for biopsy, and may thus lower the likelihood of overdetection and overtreatment of nonlethal prostate cancer.

The study, Prospective Validation of the IsoPSA Assay for Detection of High Grade Prostate Cancer, was conducted as a follow-up to early studies which demonstrated that IsoPSA, a structure-focused protein biomarker, may be an effective means of discriminating between high-grade prostate cancer (Gleason≥7) and low-grade/benign disease (Gleason=6).

The research team, led by Cleveland Clinic’s Eric Klein, M.D., conducted a multicenter validation trial and evaluated performance data with a new cohort, including cutoff parameters derived from a preliminary study, using the detection of
