Summary

This completed registry study followed nearly 1,000 Japanese men with high-risk metastatic hormone-naïve prostate cancer to see how well standard treatments work in everyday medical practice. Researchers tracked PSA levels, cancer progression, survival, and quality of life. No new drug was tested; the goal was to gather real-world data on current treatments.
