Researchers from Mount Sinai School of Medicine have identified a six-gene signature that can be used in a test to predict survival in men with aggressive prostate cancer, according to new research published in the October issue of The Lancet Oncology. This is the first study to demonstrate how prognostic markers may be useful in a clinical setting. Using blood from 202 men with treatment-resistant prostate cancer, researchers found six genes characteristic of treatment-resistant prostate cancer. Men with the six-gene signature were high-risk, with a survival time of 7.8 months, and men without it were low-risk, with a survival time of approximately 34.9 months. A replication study of 140 additional patients validated these findings. William K. Oh, MD, Chief of the Division of Hematology and Medical Oncology of The Tisch Cancer Institute at The Mount Sinai Medical Center, led the research team.
