- Genomics
- Biomarker Discovery
Background:
- Prostate cancer is a leading cause of cancer death in men.
- High-throughput sequencing is expanding molecular classification of prostate cancer.
- Translating basic science into clinical biomarkers is crucial for precision medicine.
Purpose of the Study:
- To review applications of molecular biomarkers for prostate cancer screening and prognosis.
- To explore predictive biomarker candidates for targeted therapy selection.
- To advocate for improved clinical trial designs incorporating molecular characterization.
Main Methods:
- Review of current literature on prostate cancer molecular classification.
- Analysis of potential biomarkers including ETS gene rearrangements, PTEN inactivation, and androgen receptor signaling.
- Discussion of innovations in clinical trial design for biomarker development.
Main Results:
- Identified potential biomarkers for improving screening specificity.
- Highlighted biomarkers for differentiating aggressive from indolent prostate cancers.
- Discussed biomarkers predictive of response to targeted therapies.
Conclusions:
