-  First findings from study analyzing outcomes of more than 10,000 men in national SEER database who underwent Decipher testing -

Veracyte, Inc. (Nasdaq: VCYT) today announced that new data from a large, population-based study reinforce the clinical utility of the Decipher Prostate genomic classifier. The findings, which will be shared for the first time at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, suggest that the Decipher Prostate tests are helping to guide prostate cancer treatment decisions and improve patient care.

“This is the first study linking patient data from SEER, the most commonly used cancer database in the United States, and the Decipher Prostate genomic classifier, to explore the association between Decipher Prostate test results and prostate cancer treatment decisions,” said Elai Davicioni, Ph.D., Veracyte’s medical director for urology and an author on the study. “The resulting data are exciting, because they demonstrate that population-based prostate cancer treatment patterns are independently associated with Decipher classifier scores.”

Researchers identified 10,528 patients with a primary prostate cancer diagnosis from 2010 to 2018 in the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) database who had undergone testing with either Decipher Prostate Biopsy (n=5,015) or Decipher Prostate RP (n=5,513) between 2014 and 2020. They then evaluated the association between these patients’ Decipher scores (range 0-1) and risk groups (low, intermediate and high), and the use of active surveillance and watchful waiting (AS/WW) as well as adverse pathology at the time of radical prostatectomy (RP).

Results show that use of AS/WW was highest among those men with low risk Decipher Prostate Biopsy results (41%), as compared to men who had intermediate (32%) or high risk (17%) Decipher scores. Conversely, RP usage increased based on individuals’ Decipher test risk group (19% of low, 25% of intermediate, and 34% of high risk). Researchers observed a similar association and trend by Decipher risk group in the use of radiation therapy (13% of low, 19% of intermediate, and 29% of high Decipher risk).

“These findings provide a powerful demonstration that the Decipher Prostate genomic classifiers are giving physicians and patients valuable information to help them make important and often challenging treatment decisions. In other words, the test is positively impacting patient care, as intended,” said Dr. Davicioni. “We are thrilled to be collaborating with the National Cancer Institute’s SEER program and academic researchers from leading comprehensive cancer centers and believe that these data will substantially enrich SEER’s prostate cancer registry and provide a valuable resource for oncology researchers.”

About Decipher Prostate

Decipher Prostate is a 22-gene, microarray-based genomic test intended to help inform treatment decisions for men with localized prostate cancer at initial diagnosis (Decipher Prostate Biopsy) and after surgical removal of the prostate (Decipher Prostate RP). The test reports the Decipher Score, which prognosticates a patient's risk of metastasis within five years and provides risk estimates of prostate cancer-specific outcomes. Decipher Prostate can help guide physicians to better select the appropriate therapy for a specific patient, which in turn can result in improved patient outcomes.
