About
Dr. Tatsuki Koyama is a leading biostatistician and health outcomes researcher whose work centers on improving the quality of care and functional outcomes for men with prostate cancer. His major contributions lie in leveraging large, population-based cohorts to critically evaluate surgical treatments and patient-reported outcomes. His landmark 2015 study, with 64 citations, provided crucial comparative evidence on the harms of open versus robotic prostatectomy, challenging assumptions about the superiority of robotic surgery in real-world settings. Dr. Koyama also advanced the interpretation of the widely used EPIC-26 quality-of-life questionnaire, translating domain scores into meaningful functional outcomes for patients and clinicians. His work with the CEASAR study further demonstrated the need for quality measures that are directly linked to patient outcomes. Through rigorous statistical analysis of prospective data, Dr. Koyama has helped bridge the gap between clinical practice and evidence-based care, offering vital insights that guide treatment decisions and set standards for surgical quality in prostate cancer.
