Dr. Katsuyoshi Hashine is a leading urological surgeon and researcher whose work centers on the surgical management of prostate cancer, with a particular focus on radical prostatectomy outcomes and health services research. His major contributions include pioneering the use of large-scale, multi-center retrospective data through the Medical Investigation Cancer Network (MICAN) study to analyze surgical trends in Japan. His landmark 2023 paper, cited 4 times, revealed critical shifts in radical prostatectomy utilization between 2010 and 2020 in Ehime, Japan, providing essential epidemiological insights for healthcare planning. Dr. Hashine has also made significant advances in understanding patient-centered outcomes, as demonstrated by his 2022 study on patient-reported outcomes (PROs) following robot-assisted radical prostatectomy (RARP), which examined the institutional learning curve for functional recovery. This work, cited 2 times, directly informs surgical training and quality improvement initiatives. His research bridges the gap between clinical practice and patient experience, offering evidence-based guidance for optimizing surgical approaches. Dr. Hashine’s dedication to rigorous data analysis and functional outcomes has established him as a key figure in Japanese urological oncology, shaping both surgical standards and healthcare policy.
