Attributes

Own

• id _0..1
  • Description: The 'logical' identifier of the entity within the system of record. The simple value of this attribute stands for an identifier of this data object within the system, it can be used as a reference from other objects within the same system (i.e. primary and foreign keys), and it should be unique per type of object. The same data object copied to a different system will likely have a different "id" in the new system since "id" values are system specific and do not represent persistent business identifiers. Business identifiers are assigned outside the information system and are captured in the "identifier" field. The "id" field is more likely to be a serially or randomly generated value that is assigned to the data object as it is created in a system.
  • Range: CrdchString
• identifier _0..*
  • Description: A 'business' identifier or accession number for the entity, typically as provided by an external system or authority, that are globally unique and persist across implementing systems. Also, since these identifiers are created outside the information system through a specific business process, the Identifier type has additional attributes to capture this additional metadata so the actual identifier values are qualified by the context that created those values. This additional context allows "identifier" instances to be transmitted as business data across systems while still being able to trace them back to the system of origin.
  • Range: Identifier
• subject _0..1
  • Description: The subject of this diagnosis.
  • Range: Subject
• age_at_diagnosis _0..1
  • Description: The age in days of the individual at the time of diagnosis
  • Range: Quantity
• diagnosis_date _0..1
  • Description: When the diagnosis was made.
  • Range: TimePoint
• condition _0..1
  • Description: Code that captures the condition being diagnosed (e.g. ICD-O, ICD-10, SNOMED, etc.)
  • Range: CodeableConcept
• primary_site _0..*
  • Description: The anatomical location of the primary condition
  • Range: BodySite
• metastatic_site _0..*
  • Description: The anatomical location(s) of metastatic disease
  • Range: BodySite
• stage _0..*
  • Description: The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body.
  • Range: CancerStageObservationSet
• grade _0..*
  • Description: The degree of abnormality of cancer cells, a measure of differentiation, the extent to which cancer cells are similar in appearance and function to healthy cells of the same tissue type. The degree of differentiation often relates to the clinical behavior of the particular tumor. Based on the microscopic findings, tumor grade is commonly described by one of four degrees of severity. Histopathologic grade of a tumor may be used to plan treatment and estimate the future course, outcome, and overall prognosis of disease. Certain types of cancers, such as soft tissue sarcoma, primary brain tumors, lymphomas, and breast have special grading systems.
  • Range: CancerGradeObservationSet
• morphology _0..1
  • Description: Code that represents the histology of the disease using the third edition of the International Classification of Diseases for Oncology, published in 2000, used principally in tumor and cancer registries for coding the site (topography) and the histology (morphology) of neoplasms.
  • Range: CodeableConcept
  • Examples: 8001/3, 8002/3, 8003/3, 8004/3, 8005/3
• disease_status _0..1
  • Description: A term that refers to the nature and/or clinical outcome of a disease (e.g., primary disease, metastatic disease, recurrent disease, etc.)
  • Range: CodeableConcept
  • Examples: Initial Diagnosis, Progressive Disease, Recurrent Disease, Residual Disease, Unknown, Not Reported
• prior_diagnosis _0..1
  • Description: A reference to a prior cancer diagnosis. In the case of relapse/recurrent disease, this attribute may be populated with a reference to the initial diagnosis.
  • Range: Diagnosis
• method_of_diagnosis _0..1
  • Description: The method used to confirm the patients malignant diagnosis
  • Range: CodeableConcept
  • Examples: Autopsy, Biopsy, Blood Draw, Bone Marrow Aspirate, Core Biopsy, ..
• related_specimen _0..*
  • Description: The specimen from which this diagnosis is made
  • Range: Specimen
• primary_tumor_dimensional_measures _0..1
