The ICDO Mapping Terminology contains a set of terms in NCI Thesaurus (NCIt) that have been mapped to terms with equivalent meaning in the International Classification of Disease for Oncology (ICDO). The files represent mappings to the histology (morphology) and the anatomical site (topography) terms present in the third addition of ICDO (ICDO3).
Files available for download :There are 5 tabs in each file corresponding to: Tab 1: all NCIt codes mapped to any term (both morphology and topography) in the stated version of ICDO; Tab 2: all NCIt codes mapped to the histology (morphology) terms in the stated version of ICDO; Tab 3: all NCIt codes mapped to the histology (morphology) preferred terms (PT) in the stated version of ICDO; Tab 4: all NCIt codes mapped to the anatomical site (topography) terms in the stated version of ICDO; Tab 5:all NCIt codes mapped to the anatomical site (topography) preferred terms (PT) in the stated version of ICDO.
| Spreadsheet Column | Content Description |
|---|---|
| Subset Code | The NCI Thesaurus (NCIt) concept code that has been mapped to the IDCO term. NCIt Codes are unique strings that begin with a C and are followed by a series of digits. |
| Subset Name | The name of the terminology set. |
| Concept Code | The NCI Thesaurus (NCIt) concept code attached to the concept. |
| NCIt Preferred Term | The preferred term chosen by NCI EVS that unambiguously describes the concept. |
| Relationship To Target | A property representing the relationship of the NCI Thesaurus (NCIt) concept to the term from the outside source. There are four possibilities: 1) Has Synonym: the two terms are synonymous; 2) Broader Than: the NCIt concept is broader than the mapped (target) term; 3) Narrower Than: the NCIt concept is narrower than the mapped (target) term; 4) Related To: the NCIt concept is somehow related to the mapped (target) term. |
| Target Code | A property representing the code assigned to the target term in the mapped (target) database. Some databases may not have codes. |
| Target Term | A property representing the term in an outside source that has been mapped to a term within the NCI Thesaurus. |
| Target Term Type | A property representing the term type designation in the mapped (target) database. |
| Target Terminology | A property representing the name of the terminology to which the NCI Thesaurus term is being mapped. In this case ICDO3 |
| Target Terminology Version | A property representing the version of the terminology to which the NCI Thesaurus term is being mapped. |
