Veracyte reported a retrospective analysis of 401 patients from the randomized Phase III STAMPEDE trial, treated with androgen deprivation therapy alone or with abiraterone added, showing that the Decipher Prostate Genomic Classifier predicts who benefits from abiraterone in clinically very high risk prostate cancer that has not spread. Adding abiraterone cut distant metastasis at five years by 10 percent for high scores and 11 percent for very high scores, against 2 percent for lower scores, and the difference was significant in patients without node involvement (p=0.01). The data were presented at ESMO 2026 on 24 October.
Our readOncologists could use the score to decide which very high risk patients gain from abiraterone and which can be spared its side effects and cost, moving Decipher from prognosis toward treatment selection. An earlier STAMPEDE analysis was recently added to the NCCN prostate cancer guidelines for high and very high risk disease.
