Radiation Oncology

Dr. Lisa Barbera, Division Head

Kelsey Knock, Administrative Assistant

The Division of Radiation Oncology currently includes 24 (21.8 FTE) radiation oncologists. All have clinical appointments within the Cumming School of Medicine at the University of Calgary and active staff appointments with Alberta Health Services. We provide Radiation Oncology services to the population of Southern Alberta. The majority of the faculty, clinical service and academic activity are at the Tom Baker Cancer Centre in Calgary but two faculty are full-time at the Jack Ady Cancer Centre in Lethbridge and one is at the Cancer Centre in Grand Prairie. Inpatients under our care are admitted to Foothills Medical Centre, which adjoins the Tom Baker Cancer Centre.

Cancer is a leading cause of illness and death in Canada. Radiation therapy relieves suffering, prolongs survival, and in many cases, cures the disease. To achieve these benefits for patients we use linear accelerators, orthovoltage external beam RT units, high dose rate brachytherapy, permanent seed brachytherapy, Intensity Modulated Radiotherapy (IMRT), and stereotactic body or CNS RT.


To provide exceptional patient care in an academic and outcomes-evaluation environment.

Strategic Plan

  • Precision RT
    • Use of MR in RT
    • Brachytherapy
    • SABR / SRS
  • Person Centred Radiation Oncology Service Enhancement (PROSE)
    • Integration and use of patient reported outcome measures
    • Integration and use of patient reported experience measures
  • Learning Healthcare System
    • Development of infrastructure to learn from every patient encounter
    • Incorporating AI within the radiotherapy treatment planning and delivery process
  • Education
    • Growth in undergraduate and fellowship training opportunities
    • Prior hosts of national examination refresher course
  • Translational research
    • cervix, anal, lung and head/neck cancer


Our division is highly committed to teaching.  The Radiation Oncology Residency Training Program is led by Dr. Shaun Loewen, and is fully accredited by the Royal College of Physicians and Surgeons of Canada. At the end of their training, our residents have been uniformly successful at their Royal College examinations, and in securing fellowship and staff positions. We host a growing number of clinical research fellows from Canadian and International centers. Fellowship experiences have included stereotactic radiosurgery, image guided RT, brachytherapy, palliative RT, translational research and person centred care. We are pleased to provide observerships and elective experiences of any length at the undergraduate and postgraduate levels.


We have organized our research programs along three broad streams:

  • Translational research, with current activity focusing largely on gynecologic, head and neck, anal and lung cancers.
  • Investigation of new technologies, including brachytherapy, stereotactic radiosurgery, IMRT and IGRT.
  • Population and outcome studies; including access to cancer services.

In addition, we are active participants in several cooperative clinical trial groups including the NCIC-CTG, OCOG, NRG Oncology Group, and the Children’s Oncology Group.
