About

Dr. Kyo Togashi is a leading urologic oncologist whose research focuses on the intersection of frailty, geriatric assessment, and surgical outcomes in prostate cancer. His major contributions include pioneering the use of frailty screening tools—such as the Geriatric 8 (G8) score—to predict postoperative complications, pain severity, and quality of life in elderly patients undergoing robot-assisted radical prostatectomy (RARP). Through landmark studies like the FRART-PC, FRAP, and FRARP-QL trials, Dr. Togashi has demonstrated that frailty and comorbidity are stronger predictors of surgical contraindication and adverse outcomes than chronological age alone. His work has been cited over 75 times, with key papers showing that frail patients are at significantly higher risk for moderate-to-severe pain after RARP and experience worse long-term quality of life and urinary symptoms. Additionally, Dr. Togashi has explored novel biomarkers, such as total cell-free DNA (cfDNA), to objectively quantify surgical damage in urological procedures. His research is reshaping how clinicians evaluate and counsel older men with localized prostate cancer, advocating for personalized, frailty-informed surgical decision-making rather than age-based cutoffs.
