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-BreastCancerHistologicGrade-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.
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).
