Background

Biography

Short bio summary:  

Dr. Sean Hassan is a radiation oncologist at the Arthur J.E. Child Comprehensive Cancer Centre and a Clinical Assistant Professor in the Department of Oncology at the University of Calgary. He completed medical school and radiation oncology training in Sydney, Australia, followed by fellowships at the Princess Margaret Cancer Centre in Toronto, where he was named Best Fellow and received a University of Toronto Residents' Award for Excellence in Clinical Teaching. His clinical practice focuses on hematological and gastrointestinal malignancies, with an emphasis on helping patients understand their disease and their treatment options. 

Dr. Hassan is the radiation oncology lead for hematological malignancies and consultant for the Alberta Bone Marrow Transplant Program. He serves on the executives of the Provincial Hematology and Gastrointestinal Tumour Teams, contributing to provincial clinical practice guidelines, and is the cancer centre's radiation oncology representative to the Canadian Cancer Trials Group (CCTG) Hematology Disease Site Committee. His research centres on cutaneous lymphoma, as part of the Calgary Cutaneous Lymphoma Multidisciplinary Program, and on combining radiotherapy with radioligand therapy, work recognized with a Canadian Radioligand Therapy Innovation Award. He sits on the national governing committee of the Canadian Skin Lymphoma Network. Active in global oncology since residency, he is a member of the Canadian Association of Radiation Oncology (CARO) IIDEA/Global Health Committee and the Calgary representative on the Canadian Global Oncology Network steering committee. He also contributes to resident education as a member of the University of Calgary Radiation Oncology Residency Program Competency Committee.

Summary of Research

Dr. Hassan's research aims to improve the precision, effectiveness and accessibility of radiotherapy, with a primary focus on cutaneous lymphoma. As a member of the Calgary Cutaneous Lymphoma Multidisciplinary Program, the national governing committee of the Canadian Skin Lymphoma Network, and the International Lymphoma Radiation Oncology Group (ILROG), he examines how radiotherapy is best used alongside systemic, cellular and emerging therapies for patients with cutaneous and other lymphomas.

He is also interested in the synergy between radiotherapy modalities. He is the Principal Investigator of a study of dosimetry-guided stereotactic ablative radiotherapy (SABR) for patients with metastatic neuroendocrine tumours receiving ¹⁷⁷Lu-DOTATATE, funded by a Novartis Canadian Radioligand Therapy Innovation Award. The study explores whether external beam radiotherapy can complement radioligand therapy by targeting lesions that receive a low absorbed dose.

Dr. Hassan's involvement in global oncology began in residency, when he served for five years as the trainee representative on the Royal Australian and New Zealand College of Radiologists' Asia-Pacific Radiation Oncology Special Interest Group (APROSIG), coordinating projects across the region, including an outreach trip to Cambodia in collaboration with the IAEA and WHO. He has published on the role of radiation oncologists in supporting radiotherapy services in low- and middle-income countries. He is a member of the Canadian Association of Radiation Oncology (CARO) IIDEA/Global Health Committee and the Calgary representative on the steering committee of the Canadian Global Oncology Network.
