RadiationTherapy¶
Radiation therapy (or radiotherapy) uses ionizing radiation, generally as part of cancer treatment to control or kill malignant cells.
Data model¶
Field | Type | Multiplicity | Description |
---|---|---|---|
modality | OntologyClass | 1..1 | The modality of radiation therapy (e.g., electron, photon,…). REQUIRED. |
body_site | OntologyClass | 1..1 | The anatomical site where radiation therapy was administered. REQUIRED. |
dosage | int32 | 1..1 | the total dose given in units of Gray (Gy). REQUIRED. |
fractions | int32 | 1..1 | The total number of fractions delivered as part of treatment. REQUIRED. |
Explanations¶
modality¶
Terms from the NCIT can be used to represent the modality of radiation therapy. Four examples are shown here:
- Electron Beam (NCIT:C28039)
- Proton Radiation (NCIT:C40431).
- Photon Beam Radiation Therapy (NCIT:C104914)
- High-LET Heavy Ion Therapy (NCIT:C15458).
The NCIT terms themselves specify whether the radiation therapy was administered externally or internally. For instance, NCIT terms from the Internal Radiation Therapy (NCIT:C15195) subhierarchy would be used to indicate a type of internal radiation therapy.
dosage¶
The total dosage administered, indicated in units of Gray.
fractions¶
The number of fractions into which the radiation dosage was divided.
