Decipher Genomic Test Predicts Chemotherapy Benefit in Metastatic Prostate Cancer
- The Decipher Prostate Genomic Classifier test successfully identified metastatic prostate cancer patients who benefit from docetaxel chemotherapy, showing a 36% reduction in death risk for high-scoring patients.
- Among 832 metastatic prostate cancer patients in the STAMPEDE trial, those with high Decipher scores had significant survival improvement with docetaxel, while lower-scoring patients showed minimal benefit.
- The 22-gene test becomes the first molecular diagnostic with randomized trial evidence to guide chemotherapy decisions in metastatic prostate cancer, potentially sparing patients from unnecessary treatment side effects.
- Additional analysis revealed that combining Decipher scores with PTEN status further refined patient selection, with high Decipher/PTEN inactive tumors showing 45% reduction in death hazards with docetaxel.
