Mechanistically, while stimulation with the AR-agonist R1881 is sufficient to induce nuclear translocation of AR in AR+ TNBC cells, AR inhibition with enzalutamide, apalutamide, or darolutamide blocked AR nuclear translocation. These findings suggest that AR-mediated radioresistance is at least partially due to downstream MAPK/ERK signaling. Together this work builds on the mechanistic understanding of AR-mediated radioresistance in AR+ TNBC which may expose vulnerabilities in resistance to combination treatment with AR inhibition and RT.

He was treated with free water restriction, hypertonic saline, and triplet systemic therapy (docetaxel, androgen deprivation, and darolutamide) and discharged in stable condition. Management of these complications requires addressing the underlying cancer with definitive treatment. The case highlights the vigilance for atypical paraneoplastic manifestations, the need for early genomic testing, and the exploration of novel therapeutic strategies in BRCA2-driven prostate cancer.
