About

Dr. Osamu Soma is a leading urological oncologist whose research centers on the intersection of geriatric oncology and prostate cancer care, with a particular focus on frailty assessment and perioperative outcomes. His work has been instrumental in demonstrating how the Geriatric 8 (G8) screening tool can be used to predict treatment patterns and clinical outcomes in elderly prostate cancer patients. In a landmark 2020 study involving 540 patients, Dr. Soma established the association between G8 scores and treatment selection across disease stages, providing a practical framework for personalizing care in older adults. His FRAP study further advanced the field by identifying frailty as a significant predictor of moderate to severe pain following robot-assisted laparoscopic prostatectomy, a finding that has direct implications for pre-surgical counseling and pain management protocols. With his most cited work accumulating over 40 citations, Dr. Soma has emerged as a key voice in the movement toward frailty-guided decision-making in urologic oncology, helping to ensure that treatment intensity aligns with patient resilience rather than chronological age alone.
