About
Shyh-Chyi Chang is a leading urological oncologist whose research focuses on optimizing surgical outcomes for prostate cancer, particularly through comparative effectiveness studies of radical prostatectomy techniques. His major contributions center on evaluating how surgical approach—open, laparoscopic, or robotic-assisted—and hospital volume affect patient prognosis. In a pivotal 2020 nationwide cohort study using the Taiwan Cancer Database (16 citations), Chang demonstrated that positive surgical margin rates and biochemical-failure-free survival did not significantly differ among open, laparoscopic, or robotic radical prostatectomy, challenging assumptions about robotic superiority. Expanding this work in a 2021 study (17 citations), he revealed that higher hospital volume was associated with improved outcomes, particularly for robotic surgery, providing critical evidence for centralizing complex cancer care. These findings have informed clinical guidelines and hospital policy in Taiwan. Chang’s rigorous use of national registry data and focus on real-world outcomes has made him a key voice in evidence-based urologic oncology, helping surgeons and patients make informed decisions about prostate cancer treatment.
