0. CancerConditionAtDiagnosis
Definition | Logical model representing the cancer condition at first diagnosis, capturing initial tumour characteristics and the diagnostic context that initiates the cancer journey. Derived from Cancer_Common_Logical_Model_20260521.xlsx (sheet CancerConditionAtDiagnosis).
Short | CancerConditionAtDiagnosis
Control | 0..*
Is Modifier | false
Logical Model | Instances of this logical model are not marked to be the target of a Reference
Invariants | ccad-1: At least one of visitDate, biopsyDate, imagingDate, labReportDate must be present, since the model requires a diagnosis date for the Cancer Condition. (`(visitDate | biopsyDate | imagingDate | labReportDate).exists()`)
2. CancerConditionAtDiagnosis.subject
Definition | Reference to the patient (subject) affected by the cancer condition at first diagnosis.
Short | Subject
Control | 1..1
Type | Reference(Cancer Patient)
4. CancerConditionAtDiagnosis.histologyBehaviour
Definition | Histology and behaviour of the neoplasm at first diagnosis. Histology describes the tumour cell type (morphology), while behaviour indicates whether the tumour is malignant, benign, carcinoma in situ, or of uncertain/borderline malignancy. This information may be unavailable during early diagnostic workup (e.g., before biopsy results are final) but is expected to be present once the diagnostic workup is completed.
Short | HistologyBehaviour
Comments | WG recommends ICD03, the WG will monitor possible next versions. This attribute becomes mandatory once the cancer has been diagnosed; however, during the diagnostic workup it may still be absent, as the biopsy resulting from the surgery may not yet be available.
Control | 0..1
Type | CodeableConcept
6. CancerConditionAtDiagnosis.bodySite
Definition | Primary anatomical site where the cancer condition was first detected.
Short | BodySite
Comments | WG recommends ICD03, the WG will monitor possible next versions. It is required to choose the most specific code available, meaning the most detailed code in the hierarchical terminology that precisely identifies the body site.
Control | 1..1
Type | CodeableConcept
8. CancerConditionAtDiagnosis.tumourGradeSystem
Definition | Classification system used to define tumour grade, describing how abnormal tumour cells and tissue appear under microscopic examination (e.g. Gleason for prostate cancer, FNCLCC for soft tissue sarcomas). The grading system provides an indication of the biological aggressiveness of the tumour.
Short | TumourGradeSystem
Comments | It represents the classification system used to define the tumour grade, such as Gleason (a grading system for prostate cancer) or FNCLCC (a grading system for soft tissue sarcomas).
Control | 0..1
Type | CodeableConcept
10. CancerConditionAtDiagnosis.tumourGradeValue
Definition | Grade value assigned according to the selected TumourGradeSystem. The grade reflects the degree of cellular differentiation and biological aggressiveness of the tumour and may evolve over time.
Short | TumourGradeValue
Comments | It represents the measured grade value based on the specific classification defined in the TumourGradeSystem.
Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
12. CancerConditionAtDiagnosis.visitDate

Comments | At least one of visitDate, biopsyDate, imagingDate, labReportDate must be present, since the model requires a diagnosis date for the Cancer Condition.
Control | 0..1
Type | dateTime

14. CancerConditionAtDiagnosis.biopsyDate
Definition | Date of the biopsy supporting the diagnosis (one of the diagnosis dates).

16. CancerConditionAtDiagnosis.imagingDate

18. CancerConditionAtDiagnosis.labReportDate
Definition | Date of the laboratory report supporting the diagnosis, including biomarkers when applicable.
