HL7 FHIR Implementation Guide: Breast Cancer Data, Release 1 - US Realm (Draft for Comment 2)
This page is part of the Breast Cancer Data Logical Models and FHIR Profiles (v0.2.0: 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 profile is:
http://hl7.org/fhir/us/breastcancer/StructureDefinition/oncology-TumorMargins
The edge or border of the tissue removed in cancer surgery. The margin is described as negative or clean when the pathologist finds no cancer cells at the edge of the tissue, suggesting that all of the cancer has been removed. The margin is described as positive or involved when the pathologist finds cancer cells at the edge of the tissue, suggesting that all of the cancer has not been removed.
This profile builds on US Core Results Profile.
This profile was published on Fri Aug 17 00:00:00 AEST 2018 as a draft by The HL7 Cancer Interoperability Group sponsored by Clinical Interoperability Council Work Group (CIC).
