description: Profile for observations regarding cancer stage, grade, or classification. The stage is an assessment of the extent of the cancer in the body, according to a given cancer staging classification system. The key elements are the code, method, value, and optionally, prognostic factors referenced in the hasMember (if the prognostic factor is captured in a different profile) or component (if the prognostic factor is not captured in a different profile) element. package_name: hl7.fhir.us.mcode derivation: constraint name: CancerStage type: Observation elements: referenceRange: {short: Not used in this profile, index: 8} hasMember: {short: Prognostic factors contributing to stage determination., index: 9} method: short: The staging system used. binding: {strength: preferred, valueSet: 'http://hl7.org/fhir/us/mcode/ValueSet/mcode-cancer-staging-method-vs'} mustSupport: true index: 6 value: short: The value of the stage choices: [valueCodeableConcept] index: 4 component: elements: code: short: Type of prognostic factor binding: {strength: preferred, valueSet: 'http://hl7.org/fhir/us/mcode/ValueSet/mcode-cancer-staging-prognostic-factor-type-vs'} index: 10 value: short: Prognostic factor value choices: [valueCodeableConcept] index: 12 valueCodeableConcept: {type: CodeableConcept, short: Prognostic factor value, choiceOf: value, index: 13} code: short: The type of stage information reported. binding: {strength: preferred, valueSet: 'http://hl7.org/fhir/us/mcode/ValueSet/mcode-cancer-stage-type-vs'} index: 0 valueCodeableConcept: {type: CodeableConcept, short: The value of the stage, choiceOf: value, index: 5} focus: type: Reference short: The cancer condition associated with staging assessment. mustSupport: true refers: ['http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-primary-cancer-condition'] index: 2 device: {short: Not used in this profile, index: 7} subject: type: Reference refers: ['http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-cancer-patient'] index: 1 package_version: 4.0.0 class: profile kind: resource url: http://hl7.org/fhir/us/mcode/StructureDefinition/mcode-cancer-stage base: http://hl7.org/fhir/us/core/StructureDefinition/us-core-simple-observation version: 4.0.0
