RADIATION THERAPY

Radiation therapy uses high-energy rays to combat and shrink tumour cells. When being given treatment, a patient can expect to be treated with an invisible beam of radiation that you cannot see or feel, similar to a diagnostic x-ray but with a much higher energy.

Radiation treatment is specified by two groups – radiation for cure and radiation for palliation (pain and symptom management).

Curative radiation treatment is used on its own, and often in combination with other treatments such as surgery, chemotherapy and hormone therapy. Curative treatments are usually longer and higher dose and can be associated with both short and longer term side effects.

Radiation for palliation is treatment to relieve symptoms such as pain, extend a patient’s life or improve the quality of life for a patient.

All radiation treatment is very specific to a patient’s cancer, targeted to particular parts of the body. Radiation therapy is used to treat some, but not all cancers. About 55 per cent of patients with cancer receive radiation therapy as part of their treatment.

Radiation therapy is administered at all six BC Cancer centres in the province.

Innovation in radiation therapy

Thanks to support from generous donors, Radiation therapy at BC Cancer has seen exciting forward leaps in treatment delivery technology over the last 10 years. BC Cancer provides British Columbians with highly innovative precision radiation therapy (PRT) and a world-class patient experience. 

In 2017, BC Cancer-Vancouver acquired a Vero 4DRT radiotherapy platform. VERO is one of the most advanced stereotactic body radiation therapy (SBRT) systems available in the world. SBRT involves delivering multiple beams of radiation from outside the body in a concentrated (high dose) manner from various directions, effectively targeting a tumour from every possible angle. VERO integrates several cutting-edge precision radiotherapy technologies into one.

In October 2019, the first patient in Canada was treated using VERO's “Dynamic Wave Arc” technique—right here in BC! Dynamic Wave Arc radiation involves the simultaneous rotation of the beam around the patient around two axes, as well as beam shaping to reduce radiation to healthy tissue during treatment. This is an important milestone for BC Cancer, the Canadian radiotherapy community, and most importantly, for patients whose treatment options would otherwise be limited by the proximity of sensitive organs to a tumour. 

GREATEST NEEDS IN RADIATION THERAPY

EQUIPMENT NEEDS
  • "Six Degrees of Freedom" robotic couch: This robotic couch can move up, down, sideways and tilt in two directions, precisely positioning the patient to better target their tumour for Precision Radiation Therapy (PRT). Purchasing a second “Six Degrees of Freedom” couch will increase precision radiation therapy for patients by 50% over two years.
  • Stereotactic radiosurgery (SRS): SRS allows for the delivery of high radiation doses to small regions, as in the brain, that would otherwise be untreatable or require aggressive and potentially debilitating surgery. Bringing this system to Surrey centre will provide a high precision radiotherapy option for patients in the Fraser Valley and will expand capacity for this treatment across the province. 

Clinical research support

The BC Cancer radiation therapy team is involved in innovative and cutting-edge clinical trials that encompass a wide range of tumour types as well as behavioural and screening studies. Donor support is needed to continue the team’s participation in clinical research and trials, and to continue innovative and ground-breaking work.

Currently, there are 75 clinical studies open through the radiation therapy department at BC Cancer, with 10 more opening soon. Some of the trial areas that are currently underway include:

  • Screening
  • Breast cancer
  • Lung cancer
  • Gynecological cancers
  • Pain & symptom management
  • Head & neck cancers
  • Gastrointestinal cancers
