# 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](StructureDefinition-CancerPatient.md) 
*  **Target FHIR profiles:** [PatientEuCcm](StructureDefinition-patient-eu-ccm.md), [ObservationComorbiditiesEuCcm](StructureDefinition-observation-comorbidity-eu-ccm.md)

| 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. |
