Meet the Team

The Yorkshire Kidney Screening Trial (YKST) is the first trial of its kind in the world. The study is designed and run by some of the UK's leading researchers in kidney cancer and urology from Cambridge and Leeds universities. The study is funded by Yorkshire Cancer Research, coordinated at the University of Cambridge, and delivered in partnership with Leeds Teaching Hospitals NHS Trust, the University of Leeds and Leeds City Council.

Professor Grant Stewart - Chief Investigator

Grant is an academic surgeon at the University of Cambridge with a broad and impactful portfolio of translational research and a particular interest in optimising early detection and management of patients with initially localised renal cell cancer. He has been joint Programme lead of the Urological Malignancies Programme since early 2020, following his appointment as Professor of Surgical Oncology at the University of Cambridge. With over 150 peer reviewed publications and £52 million in research grants and clinical trial income, he is a global leader in renal cell cancer research and coordinates the a group of over 40 clinicians, translational researchers and basic scientists across the Cambridge Biomedical Campus with a shared interest in renal cell cancer research (CamRenCan). Clinically, Grant provides all modes of treatment for kidney cancer, from major open surgery to robotic minimally invasive approaches.
