Compared with the SU2C/PCF mCRPC cohort, clival metastases showed significant enrichment of BRAF and CHEK2 alterations as well as homologous recombination repair (HRR) with relative depletion of AR-related, PI3K pathway, and G2-M pathway alterations.<h4>Conclusion</h4>Prostate cancers giving rise to clival metastases exhibit a distinct molecular profile enriched for DNA damage-repair and RAF kinase alterations, suggesting unique metastatic biology and potential therapeutic vulnerabilities. Here, AR is linked to prostate carcinoma.
