2020 JUN 03 (NewsRx) -- By a News Reporter-Staff News Editor at NewsRx Medical Devices Daily -- Investigators publish new report on Surgery - Prostatectomy. According to news originating from Ann Arbor, Michigan, by NewsRx correspondents, research stated, “Genomic classifiers (GC) have been shown to improve risk stratification post prostatectomy. However, their clinical benefit has not been prospectively demonstrated.”

Financial supporters for this research include Prostate Cancer Foundation, Center for Information Technology, U.S. Department of Defense, Dr. Spratt is on Janssen and Blue Earth advisory boards, Ivy Zhang is an employee of Decipher Biosciences, Tiffany Le is an employee of Decipher Biosciences, Worlanyo is an employee of Decipher Biosciences, Dr. Davicioni is an employee of Decipher Biosciences, Dr. Dabbas is an employee of Decipher Biosciences.

Our news journalists obtained a quote from the research from the University of Michigan, “We sought to determine the impact of GC testing on postoperative management in men with prostate cancer post prostatectomy. Two prospective registries of prostate cancer patients treated between 2014 and 2019 were included. All men underwent Decipher tumor testing for adverse features post prostatectomy (Decipher Biosciences, San Diego, CA). The clinical utility cohort, which measured the change in treatment decision-making, captured pre-and postgenomic treatment recommendations from urologists across diverse practice settings (n=3455). The clinical benefit cohort, which examined the difference in outcome, was from a single academic institution whose tumor board predefined ‘best practices’ based on GC results (n=135). In the clinical utility cohort, providers’ recommendations pregenomic testing were primarily observation (69%). GC testing changed recommendations for 39% of patients, translating to a number needed to test of 3 to change one treatment decision. In the clinical benefit cohort, 61% of patients had genomic high-risk tumors; those who received the recommended adjuvant radiation therapy (ART) had 2-year PSA recurrence of 3 vs. 25% for those who did not (HR 0.1 [95% CI 0.0-0.6], p=0.013). For the genomic low/intermediate-risk patients, 93% followed recommendations for observation, with similar 2-year PSA recurrence rates compared with those who received ART (p=0.93). The use of GC substantially altered treatment decision-making, with a number needed to test of only 3.”

According to the news editors, the research concluded: “Implementing best practices to routinely recommend ART for genomic-high patients led to larger than expected improvements in early biochemical endpoints, without jeopardizing outcomes for genomic-low/intermediate-risk patients.”
