New Data Suggest Decipher GRID-Derived Genomic Signature Can Help Identify Men with Prostate Cancer Who Should Receive High-Dose Radiotherapy
(Nasdaq: VCYT) announced new data demonstrating that a genomic signature derived from the companys Decipher GRID database could help determine which men experiencing prostate cancer progression following radical prostatectomy (RP) would benefit from dose-intensified salvage radiotherapy (SRT).
- (Nasdaq: VCYT) announced new data demonstrating that a genomic signature derived from the companys Decipher GRID database could help determine which men experiencing prostate cancer progression following radical prostatectomy (RP) would benefit from dose-intensified salvage radiotherapy (SRT).
- Post-Operative Radiation Therapy Outcomes Score (PORTOS) is a gene-expression signature of 24 DNA damage, repair and immune pathway genes previously shown to predict benefit from postoperative radiotherapy.
- The new data shared at ASTRO show that the subset of men with higher PORTOS scores had substantial improvement in clinical-progression-free survival (CPFS) with the higher dose of SRT (70Gy).
- Dependent on further studies, this could be the first predictive biomarker to help physicians personalize radiotherapy dose in the postoperative prostate cancer setting.
