UCA1 copy number gain in serum cfDNA predicts next-generation antiandrogen resistance in metastatic castration-resistant prostate cancer.

Specific blood markers may predict which hormone therapies will work for advanced prostate cancer, guiding smarter treatment choices.

Using WES of ENZA-resistant versus sensitive cell lines followed by digital droplet PCR validation in mCRPC patient cfDNA, UCA1 copy number gain emerged as a predictive marker for ENZA resistance; AR gain predicted abiraterone resistance. These treatment-specific cfDNA biomarkers could inform therapy selection in mCRPC but require larger prospective validation.

What the study was

Study design
Translational biomarker study (cell line WES/transcriptome + clinical cfDNA cohort)
Population
Metastatic castration-resistant prostate cancer (mCRPC) patients receiving enzalutamide, abiraterone, or docetaxel
Sample size
80
Category
Diagnostics
Maturity
Exploratory
Journal
Scientific Reports

Why it surfaced

Novel cfDNA biomarker for treatment-specific resistance in mCRPC; small exploratory cohort (n=20 per arm) limits current applicability.
