Arjun Sahgal

Dr. Arjun Sahgal is an international clinical and research leader in the field of high precision stereotactic radiation to the brain and spine for both metastases and primary tumors and to oligometastases. He has published over 600 peer-reviewed papers including in high impact journals like the Journal of Clinical Oncology, Lancet Oncology and New England Journal of Medicine, and 40 international guidelines specific to SRS and SBRT. He has given over 200 lectures as an invited international speaker. He invented the 24 Gy in 2 SBRT fractions regimen for spinal metastases which was tested in his landmark international CCTG SC24 randomized trial, proving superiority over conventional palliative radiation with respect to complete pain response. He developed the field of MR Linac adaptive radiotherapy for High Grade Glioma, and built an internationally recognized imaging and therapeutic research program. His group has presented the first trial to evaluate treatment volume reduction via weekly, on-line and real time, MR adaptive radiation (UNITED). He continues his research and collaborations specific to adaptive RT, vertebral compression fracture risk prediction using machine learning methods and leads the Canadian randomized trial of SBRT vs. conventional radiation for non-spine bone metastases (CCTG SC-29).
