研究目的:

开展前瞻性临床研究探索双极雄激素疗法(bipolar androgen therapy, BAT)序贯新型雄激素受体抑制剂或PD-1抑制剂在转移性去势抵抗型前列腺癌患者中的疗效差异,寻找患者筛选和疗效预测的生物标志物,建立晚期前列腺癌治疗新策略。  

Objectives of Study:

To conduct a prospective clinical study to explore the efficacy differences between sequential novel androgen receptor inhibitors and PD-1 inhibitors in patients with metastatic castration-resistant prostate cancer treated with bipolar androgen therapy. To identify biomarkers for patient screening and efficacy prediction, and establish new treatment strategies for advanced prostate cancer.
