Radiation therapy
Updates to Article Attributes
Body
was changed:
Radiation therapy, or radiotherapy, is a common oncologic treatment technique utilizing ionizing radiation to control or eliminate malignant cells. Radiotherapy plays a role in primary curative treatment (eg. head and neck cancer), adjuvant therapy (eg. reducing recurrence rate after local breast cancer surgery) and palliation of cancer symptoms (eg. reducing pain from bone metastases). Radiotherapy may be used alone, or synergistically with chemotherapy or immunotherapy.
Techniques
Historically radiotherapy is divided into three categories:
-
external beam radiotherapy (EBRT) where a medical linear accelerator directs ionizing radiation at the tumour from outside the body
- conventional radiation therapy
- three-dimensional conformal radiation therapy (3D-CRT)
- intensity-modulated radiation therapy (IMRT)
- stereotactic
ablativebody radiotherapy(SABR(SBRT or SABR) - stereotactic radiosurgery
- proton therapy
- sealed source radiotherapy (brachytherapy) where a radiation source(s) is placed inside or next to the tissue requiring treatment
- unsealed source radiotherapy (systemic radioisotope therapy) where a radioisotope is delivered through infusion (e.g. 177Lu-DOTATATE for neuroendocrine tumours) or ingestion (e.g. I-131 for thyroid cancer)
