|Guide for use:|
Record whether brachytherapy was administered during the initial course of treatment for cancer.
Brachytherapy is delivered by placing the radiation source in close proximity to the tumour site. The radioactive isotopes are sealed in tiny pellets or “seeds” which are placed in the body using delivery devices such as needles or catheters. Types include interstitial brachytherapy, which uses a source placed within tumour tissue, for example, within a prostate tumour; and intracavitary brachytherapy, whereby the source is placed within a surgical cavity or a body cavity. Brachytherapy can involve the temporary or permanent placement of radioactive sources.
Brachytherapy is likely to be delivered to admitted patients.
The radiotherapy treatment modality will typically be found in the radiation oncologist's summary letter for the initial course of treatment or in the radiotherapy treatment summary in the patient's medical record.
|Comments:||To evaluate patterns of radiotherapy care and analyse patient outcomes, it is necessary to know which treatment modalities were employed in the delivery of treatment.|
