About
J. Alfred Witjes is a leading urologic oncologist whose work has fundamentally shaped the management of bladder and prostate cancer. He is best known for his central role in developing the European Association of Urology (EAU) Guidelines on Muscle-invasive and Metastatic Bladder Cancer, with the 2020 edition alone accumulating over 2,100 citations, making it an indispensable clinical resource worldwide. His research focuses on optimizing surgical outcomes, particularly through comparative effectiveness studies of robot-assisted versus open radical cystectomy, and on refining risk stratification for prostate cancer. Witjes has advanced the use of multiparametric MRI for local staging, demonstrating its superiority over digital rectal examination, and has externally validated key nomograms for predicting lymph node involvement and extraprostatic extension. His work on the learning curve for intracorporeal robot-assisted cystectomy, published by the EAU Robotic Urology Section, provides crucial guidance for surgical training. With a career spanning landmark guidelines and high-impact surgical studies, Witjes has helped set the standard of care for urologic cancers while equipping clinicians with evidence-based tools for personalized treatment decisions.
