Definitions for the Radiotherapy logical model.
Guidance on how to interpret the contents of this table can be foundhere
| 0. Radiotherapy | |
| Definition | Logical model representing a radiotherapy treatment course administered to the patient, including intent, timing, and anatomical target. Derived from Cancer_Common_Logical_Model_20260521.xlsx (sheet Radiotherapy). |
| Short | Radiotherapy |
| Control | 0..* |
| Is Modifier | false |
| Logical Model | Instances of this logical model are not marked to be the target of a Reference |
| Invariants | rt-1: If endDate is present, it should be greater than or equal to startDate. (endDate.empty() or endDate >= startDate) |
| 2. Radiotherapy.subject | |
| Definition | Reference to the patient (subject) receiving radiotherapy. |
| Short | Subject |
| Control | 1..1 |
| Type | http://hl7.eu/fhir/cancer-common/StructureDefinition/CancerPatient |
| 4. Radiotherapy.cancerConditionAtDiagnosisReference | |
| Definition | Reference to the cancer condition at diagnosis targeted by radiotherapy. |
| Short | CancerCondition AtDiagnosis Reference |
| Control | 1..1 |
| Type | Reference(CancerConditionAtDiagnosis) |
| 6. Radiotherapy.clinicalCancerProgressionReference | |
| Definition | Reference to the clinical progression event, if radiotherapy is delivered in response to progression. |
| Short | ClinicalCancerProgresionReference |
| Comments | It is not only required at the time of diagnosis; it must be provided in the event of ClinicalCancerProgression. |
| Control | 0..1 |
| Type | Reference(ClinicalCancerProgression) |
| 8. Radiotherapy.intent | |
| Definition | Radiotherapy intent (Definitive/curative vs Palliative). |
| Short | Intent |
| Comments | Choice: Definitive | Palliative |
| Control | 1..1 |
| Type | CodeableConcept |
| 10. Radiotherapy.startDate | |
| Definition | Start date of the radiotherapy course. |
| Short | StartDate |
| Control | 1..1 |
| Type | dateTime |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| 12. Radiotherapy.endDate | |
| Definition | End date of the radiotherapy course (may be missing while ongoing). |
| Short | EndDate |
| Comments | It might not be available while the radiotherapy is still ongoing; however, an end date must eventually be recorded, which in the most extreme case will coincide with the patient's date of death. |
| Control | 0..1 |
| Type | dateTime |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| 14. Radiotherapy.bodySite | |
| Definition | Anatomical site(s) targeted by radiotherapy. |
| Short | BodySite |
| Control | 1..* |
| Type | CodeableConcept |
| 16. Radiotherapy.setting | |
| Definition | Strategic timing/setting of radiotherapy (e.g. neoadjuvant, adjuvant, concomitant, alone). |
| Short | Setting |
| Comments | Choice: Alone | Preoperative/Neoadjuvant | Postoperative/Adjuvant | Concomitant |
| Control | 0..1 |
