PI3K-Akt-mTOR and androgen receptor (AR) signaling are commonly aberrantly activated in metastatic castration-resistant prostate cancer (mCRPC), with PTEN loss associating with poor prognosis.
Aberrations of AR, ETS genes, TP53, and PTEN were frequent (40%-60% of cases), with TP53 and AR alterations enriched in mCRPC compared to primary prostate cancer.

To evaluate everolimus, an inhibitor of mTOR, in patients with metastatic castration-resistant prostate cancer (mCRPC), and to explore potentially predictive serum biomarkers by proteomics, the significance of PTEN status in tumor tissue, and the impact of everolimus on immune cell subpopulations and function.
