Brief 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, enzaluta...
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 pros...

- Patient is at a castration level and the testosterone level is lower than \<50 ng/dL or 1.7 nmol/L;
- Received abiraterone or enzalutamide and other new second-generation anti-androgenic drugs and have disease progression. Disease progression is defined by PCWG3 :The progression of disease in PCWG3 is defined as satisfying one of the following: according to the increase in PSA levels, there must be three consecutive increases in PSA at least one week apart, and the minimum value is greater than or equal to 5.0 ng/ml; disease progression as assessed by RECIST 1.1, considering PSA levels or not; PCWG3 defines bone disease progression, which is bone scan found 2 or more new lesions;
- Evidence of distant metastatic disease (such as bone scans and CT/MRI results), imaging data that can be used to assess the condition before and after treatment, or imaging experience provided by three imaging hospitals with experience in three hospitals. Test reports and oncology indicators include PSA values;
- The patient can tolerate the primary physician to perform the puncture operation, after receiving the informed consent from the patient and the family members;
- The follow-up period must be at least greater than 2 months;
- Be able to follow the research and follow-up procedures to provide real and effective information;
- The patient or his legal guardian understands the test procedure and content and voluntarily signs the printed informed consent form.
Exclusion
- Cognitive ability and psychological abnormalities
- ECOG score 3-4 points or blood biochemical examination indicates that the patient is not suitable for continuing chemotherapy or chemotherapy has been postponed
- Can not provide enough tumor puncture tissue, not enough tumor cells for subsequent experiments;
- Patient who is unwilling to receive follow-up treatment after the Mini PDX model drug sensitivity test;
- The investigator believes that the subject may not be able to complete the study or may not be able to comply with the requirements of this study (for administrative reasons or other reasons).
