Dr Nicholas Van As qualified in medicine in 1995 in South Africa and completed specialist training in clinical oncology at Guy’s and St Thomas’ Hospital, The Royal Marsden and The Institute of Cancer Research.
Dr Van As specialises in urological cancers. He has research interests in stereotactic and image-guided radiotherapy, risk prediction in early prostate cancer, and functional MRI. He has published numerous papers and delivered presentations at international meetings.
Dr Van As is the clinical lead for CyberKnife and leads the stereotactic radiotherapy MDT at The Royal Marsden. He is the chief investigator on the PACE trial. This is the largest international trial looking at stereotactic radiotherapy for prostate cancer. CyberKnife is an exciting new technology which allows the accurate delivery of high-dose image-guided radiotherapy. It has been operational at The Royal Marsden since summer 2011.
