## CancerPatient Mapping - FHIR

CancerPatient -> PatientEuCcm / ObservationComorbiditiesEuCcm
Future implementation content This page is provided to show the expected direction of future implementation work. It is not part of the proposed material for evaluation in this publication; mappings, target artefacts and profiling details are expected to evolve in subsequent iterations of this guide.
Yellow row/cells: In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

### CancerPatient -> PatientEuCcm / ObservationComorbiditiesEuCcm

This page explains how elements from the CancerPatient logical model are expressed in the PatientEuCcm and ObservationComorbiditiesEuCcm profiles used by this Implementation Guide.

Mapping Context

- Source logical model: CancerPatient
- Target FHIR profiles: PatientEuCcm, ObservationComorbiditiesEuCcm

CancerPatient -> PatientEuCcm / ObservationComorbiditiesEuCcm
CancerPatient (Logical Model) | Relationship | PatientEuCcm / ObservationComorbiditiesEuCcm
--- | --- | ---
Element | Relation | Resource | Element | Notes
birthDate | equivalent | Patient | birthDate | Use partial date if only year/month is known.
sexAtBirth | equivalent | Patient | extension[recordedSexOrGender] | Use recordedSexOrGender with type = $loinc#76689-9 "Sex assigned at birth"
observedSexGender | related-to | Patient | gender | Use gender when appropriate; consider an extension if distinct from administrative gender.
comorbiditiesAtCancerDiagnosis | related-to | Observation | extension[comorbidConditionPresent] | Use ObservationComorbiditiesEuCcm to represent present comorbidities.
comorbiditiesAtCancerDiagnosis | related-to | Observation | extension[comorbidConditionAbsent] | Use ObservationComorbiditiesEuCcm to represent absent comorbidities.
