Unearthing a Prostate Cancer cfDNA Signature that “Stems” from AR Alterations

Androgen receptor alterations portend a poor prognosis in patients with advanced prostate cancer. A recent study identified a stemness signature enriched in cell-free DNA from androgen receptor–altered patients, associated with worse outcomes. These findings highlight the potential of epigenomic liquid biopsy tools to discover novel clinically relevant tumor molecular subtypes.
