About
Mark Preston is a urologic surgeon and researcher whose work focuses on improving surgical outcomes in prostate cancer treatment, particularly through the study of nerve-sparing techniques and surgical margins. His most cited paper (65 citations) examines the critical trade-off between nerve preservation during radical prostatectomy and the risk of positive surgical margins, a key factor in cancer control. He further advanced this area by investigating the prognostic significance of capsular incision into tumor during prostatectomy (37 citations), helping to refine surgical quality standards. Beyond the operating room, Preston has contributed to surgical education, leading surveys that assessed Canadian senior resident training in laparoscopy, robotics, and endourology—work that highlighted gaps in hands-on experience and helped shape curriculum development. His research directly informs the balance urologists must strike between functional outcomes and oncologic safety. With a career dedicated to evidence-based refinement of surgical technique and training, Preston’s work continues to influence how prostate cancer surgery is taught and performed, ultimately benefiting both surgeons and the patients they treat.
