    Title:

    Circulating tumor DNA-targeted sequencing to reveal germline and somatic alterations that can guide decision-making in metastatic castration-resistant prostate cancer.

    Published date:
    05/28/2020
    Excerpt:
    AR amplification and TP53 or RB1 defect were associated with resistance to abiraterone or docetaxel. CDK12 was more frequently altered in our cohort than those in previous reports which mainly focused on Caucasian population. The patients with CDK12 defect showed rapid resistance to abiraterone and limited efficacy of Poly (ADP-ribose) polymerase inhibitors (PARPi). However, these patients seemed to benefit from chemotherapy, especially platinum-based chemotherapy.
