Dr. Greg Zagaja specializes in urologic oncology. He is director of the prostate cancer program and has been critical in the development of the University of Chicago Robotic Surgery Program. His areas of expertise are in the management of prostate and bladder cancer. Dr. Zagaja has been a national leader in the development of robotic assisted laparoscopic surgery for the management of prostate cancer. Utilizing minimally invasive surgical techniques, prostate cancer surgery can be performed with similar cancer control rates, when compared to open surgery, while preserving urinary control and sexual function. Dr. Zagaja and his colleagues have critically analyzed their outcomes data assessing the robotic technique. Implementing surgical modifications to the robotics approach, he has helped to maximize quality of life outcomes while ensuring optimal cancer control.


Dr. Zagaja is actively involved in clinical research assessing outcomes as related to prostate cancer surgery, and a multi-institutional study assessing the role of adjuvant chemotherapy (docetaxel) in the management of high risk prostate cancer. He is a reviewer for multiple urological journals, and advisor to the University of Chicago, Clinical Trials Review Committee.
