Summary

The investigators intend to use the Second-generation sequencing（NGS）and MiniPDX drug sensitivity models to guide the treatment decision-making for patients who were resistant to abiraterone, enzalutamide or other new second-generation anti-androgenic drugs. In order to develop precise personalized treatment plans for patients and extent their lifetimes.

Detailed description

Most patients with metastatic prostate cancer are effective in endocrine therapy at the beginning, but after a median survival of 12 to 18 months, almost all patients develop castration-resistant prostate cancer (CRPC). Since the pathogenesis of CRPC is still unknown, the clinical lack of precise treatment for the cause is a difficult and hot topic in current research and treatment. Mini patient derived xenograft (MiniPDX) is a drug sensitivity test model established by transplanting primary human tumor cells into immunodeficient mice by special methods. This efficient drug sensitivity test can provide sensitivities of single drug or drug combination in order to screen out the optimal individualized regimens for each patient.
