Inclusion criteria

Inclusion criteria: 1. Age > 20, Japanese men at the time of informed consent. 2. Patients who provided informed consent. If the patient has died, opt-out will be applicable. 3. Patients who are diagnosed as mCRPC between January 1st in 2014 and December 31st in 2018. 4. Patients who have a FFPE tumor sample (primary or metastatic) with Formalin Neutral Buffer Solution 5. Patients which the investigator judges to secure the enough amount of tumor samples from future laboratory test

Exclusion criteria

Exclusion criteria: 1. Patients who have failed HRR-related gene mutation testing with the myChoice HRD plus in screening period. 2. Patients who have an only FFPE primary tumor sample (primary or metastatic) with unbuffered formalin including acidic formalin. 3. Patients who have taken an investigational medical product for prostate cancer from Jan 1st , 2014 to Dec 31st 2020.
