The purpose of this study is to evaluate the yearly conditional prostate-specific antigen (PSA) progression-free survival (PFS) probabilities in high-risk localized prostate cancer (HR LPC) participants following radical prostatectomy (RP) and perioperative hormonal therapies (that is, hormonal treatment before RP and / or after RP) over 5 years.

| Participants With High-risk Localized Prostate Cancer | Adult participants from Japan, South Korea, and Taiwan with high-risk localized prostate cancer (HR LPC) who received radical prostatectomy (RP) and perioperative (neoadjuvant and/ or adjuvant) hormonal therapy will be observed from the date of confirmed HR LPC diagnosis until death, lost to follow-up (last known visit), or end of study period, whichever comes first. This study will utilize data from electronic medical records (EMR) in South Korea and Taiwan, and data from chart reviews in Japan. Data will be analyzed retrospectively from 1 January 2015 to 30 June 2017, with a follow-up till 30 June 2022. |

| Measure | Description | Time Frame |
|---|---|---|
| Yearly Conditional Prostate-specific Antigen (PSA) Progression-free Survival (PFS) Probability | PSA PFS probability is defined as probability of being PSA progression free given that participant has yet to experience PSA progression or death from any cause. PSA progression is defined as per the prostate cancer working group 2 (PCWG2) consensus. | Up to 5 years |
| Measure | Description | Time Frame |
|---|---|---|
| Localized Prostate Cancer (LPC) Stage at Diagnosis | LPC stage at diagnosis will be based on the latest tumor nodes and metastases (TNM) staging system approved by the American Joint Committee on Cancer (AJCC). | Up to 2.5 years |
| Time from Diagnosis of LPC to Radical Prostatectomy (RP) |
