HL7 FHIR® Implementation Guide: Breast Cancer Data, Release 1 - US Realm (Draft for Comment)
This page is part of the Breast Cancer Data Logical Models and FHIR Profiles (v0.1.0: STU 1 Draft) based on FHIR R3. . For a full list of available versions, see the Directory of published versions 
The official URL for this logical model is:
http://hl7.org/fhir/us/breastcancer/StructureDefinition/oncology-BreastCancerStage-model
The stage of a breast cancer. Different staging systems use different staging groups, so there are currently no terminology bindings associated with this class.
This logical model was published on Sun Apr 01 00:00:00 AEDT 2018 as a draft by The HL7 Cancer Interoperability Group sponsored by Clinical Interoperability Council Work Group (CIC).

|---|---|---|---|---|
  oncology-BreastCancerStage-model | 0..* | |||
  evaluationResultTopic | 1..1 | BackboneElement | The base class, independent of context, for evaluations (measurements, tests, or questions) and a value containing the result (answer). | |
 valueCodeableConcept | 0..1 | Coding | A set of codes drawn from different coding systems, representing the same concept. Binding: BreastCancerStageVS (example) | |
 topicCode | 1..1 | TopicCodeModel | The concept representing the finding or action that is the topic of the statement. | |
 value | 1..1 | Coding | Malignant Neoplasm of Breast Staging | |
  system | Σ | 1..1 | uri | Identity of the terminology system Fixed Value: http://ncimeta.nci.nih.gov |
| version | Σ | 0..1 | string | Version of the system - if relevant |
| code | Σ | 1..1 | code | Symbol in syntax defined by the system Fixed Value: C2216702 |
| display | Σ | 0..1 | string | Representation defined by the system |
| userSelected | Σ | 0..1 | boolean | If this coding was chosen directly by the user |
| findingMethod | 0..1 | FindingMethodModel | The technique used to create the finding; for example, the specific imaging technique, lab test code, or assessment vehicle. | |
| interpretation | 0..1 | InterpretationModel | A clinical interpretation of a finding. | |
| category | 1..* | CategoryModel | A class or division of people or things having particular shared characteristics | |
| value | 1..1 | Coding | Code representing a class or division of people or things having particular shared characteristics Binding: Observation Category Codes (extensible) | |
| deltaFlag | 0..1 | DeltaFlagModel | Indicator of significant change (delta) from the last or previous measurement. | |
| precondition | 0..* | PreconditionModel | A description of the conditions or context of an observation; for example, under sedation, fasting or post-exercise. | |
| evaluationComponent | 0..1 | A simplified, non-separable evaluation consisting of a finding code (represented by the Concept), value (or exception value), reference range, and interpretation. | ||
| breastCancerPrimaryTumorClassification | 0..1 | BreastCancerPrimaryTumorClassificationModel | The size and extent of the primary tumor, based on criteria defined by the staging system being used. | |
| breastCancerRegionalNodesClassification | 0..1 | BreastCancerRegionalNodesClassificationModel | The presence of metastases in regional lymph nodes, based on criteria defined by the staging system being used. | |
| breastCancerDistantMetastasesClassification | 0..1 | BreastCancerDistantMetastasesClassificationModel | The presence of distant metastases, based on criteria defined by the staging system being used. | |
| recordedContext | 1..1 | RecordedContextModel | Context for an evaluation result, used to indicate an evaluation has been made. | |
| encounter | 0..1 | EncounterModel | An abstract class that represents an encounter class. This class has been stubbed out to limit the scope of this implementation guide to classes relevant to this ballot concerning breast cancer. | |
| members | 0..1 | BackboneElement | Members represent the elements of a group of a related but independent evaluations. | |
| value | 0..1 | EvaluationResultRecorded representing members represent the elements of a group of a related but independent evaluations. | ||
 hER2ReceptorStatus | 0..1 | Reference(BC HER2ReceptorStatus Logical Model) | HER2 receptor status. HER2 is a member of the human epidermal growth factor receptor family of proteins and is encoded by the ERBB2 oncogene. HER2 is overexpressed in 20-30% of breast tumors,10 and is associated with an aggressive clinical course and poor prognosis. HER2 status (positive=present or overexpressed; negative=absent) is a factor in determining prognosis and treatment options. | |
| estrogenReceptorStatus | 0..1 | Reference(BC EstrogenReceptorStatus Logical Model) | Estrogen receptor alpha is the predominant estrogen receptor expressed in breast tissue and is overexpressed in around 50% of breast carcinomas. ER status (positive=present or overexpressed; negative=absent) is a factor in determining prognosis and treatment options. | |
| progesteroneReceptorStatus | 0..1 | Reference(BC ProgesteroneReceptorStatus Logical Model) | Progesterone receptor status is a factor in determining prognosis and treatment options. The value is the percentage of cells that test (stain) positive for the presence of a receptor. The interpretation of positive or negative (found in the interpretation property) is based on the staining percentage, and may take into account the staining intensity. | |
| dCISNuclearGrade | 0..1 | Reference(BC DCISNuclearGrade Logical Model) | An evaluation of the size and shape of the nucleus in tumor cells and the percentage of tumor cells that are in the process of dividing or growing. Cancers with low nuclear grade grow and spread less quickly than cancers with high nuclear grade. | |
| breastCancerHistologicGrade | 0..1 | Reference(BC BreastCancerHistologicGrade Logical Model) | The Elston Grade/Nottingham Score, representative of the aggressive potential of the tumor. Well differentiated cells (Grade 1) look similar to normal cells and are usually slow growing, while poorly differentiated cells (Grade 3) look very different than normal and are fast-growing. | |
| stageTimingPrefix | 0..1 | StageTimingPrefixModel | Indicates when the staging was done, in terms of treatment landmarks. | |
