 ====== NAACCR ======
-NAACCR (North American Association of Central Cancer Registries) is a data standard used to code data in the US Cancer Registries. NAACCR is arguably the best existing data dictionary that covers majority of cancer types and includes critical diagnostic features and high level treatment classification used in cancer epidemiology.
+Thank you for visiting the wiki! This page has moved to https://github.com/OHDSI/Vocabulary-v5.0/wiki/Vocab.-NAACCR.
-=== Source structure ===
-NAACCR data is not provided in a form of standard ontology. They exist as a list of different cancer-related variables provided with a list of valid values and their codes. Variables themselves are split into schemas representing diagnostically related groups of neoplasms, such as lymphomas or esophageal neoplasms.
-Source tables used for ingestion of NAACCR into OMOP CDM are derived using SEER API.
-=== Internal hierarchy ===
-All NAACCR concepts form ontology from __Schema__ over __Variable__ to __Value__ level. All relationships are stated explicitly through levels, meaning that __Values__ have relations directly to __Schema__ level. Concepts on variable level are also united in kind of hierarchy indicated by relationship_id 'Has parent item' and 'Date of variable'. __Variables__ that belong to mpore than one __Schema__ have stated relations to all of them. Such __Variables__ also don't specify a schema name in their code.
-Currently, source ontology does not participate in forming [[documentation:cdm:concept_ancestor|CONCEPT_ANCESTOR table]], but is fully present in [[documentation:cdm:concept_relationship|CONCEPT_RELATIONSHIP table]].
-=== Code format ===
-All NAACCR codes are ontological, meaning they are built by concatenating all preceding ontological levels to capture meaning.
-Example of code for value representing extent of tumor of colon:
-| **colon**@**2810**@**050** | (Adeno)carcinoma, noninvasive, in a polyp or adenoma|
-Value code contains parent schema name (**colon**), variable code (**2810**) and proper value code (**050**).
-=== Concept classes ===
-^ Schema level ^ Description ^
-| NAACCR Schema | Top level of hierarchy, grouper concepts |
-| NAACCR Proc Schema | Schemas exclusively containing medical and surgical procedures related to cancers |
-^ Variable level ^^
-| NAACCR Variable | Variables belonging to schemas |
-^ Value level ^^
-| NAACCR Value | Concepts representing permissible values for most variables |
-| NAACCR Procedure | Medical procedures belonging to specific schemas |
-| Permisssible Range | Concepts representing certain numeric ranges as answers |
-=== Domains by class ===
-NAACCR concepts belong to different domains depending on their clinical meaning.
-^ Schema level ^ Possible DOMAIN_ID ^ Description ^
-| NAACCR Schema | Observation | Hierarchical level, so concepts are non-specific groupers |
-| NAACCR Proc Schema | ::: | ::: |
-^ Variable level ^^^
-| NAACCR Variable | Measurement, Observation, Metadata, Episode | Various domains depending on clinical meaning |
-^ Value level ^^^
-| NAACCR Value | Meas Value, Procedure, Observation, Drug | Concepts representing permissible values for most variables. Meas value is the most common, other domains are chosen depending on parent variable domain |
-| NAACCR Procedure | Procedure, Observation | Procedure domain is default. Observation domain is for concepts indicating special procedure context (e.g. procedure not performed) |
-| Permisssible Range | Meas Value | Concepts representing certain numeric ranges as answers |
-=== Standard status and mapping, by class ===
-NAACCR concepts currently do not have active mappings to concepts from other vocabularies, excluding some NAACCR variables which are mapped to Standard concepts in [[documentation:vocabulary:episode|Episode]] vocabulary.
-^ Schema level ^ Description ^
-| NAACCR Schema | Non-standard without mapping |
-| NAACCR Proc Schema | ::: |
-^ Variable level ^^
-| NAACCR Variable | Standard and non-standard concepts; non-standard concepts may have mapping to standard concepts |
-^ Value level ^^
-| NAACCR Value | Standard and non-standard unmapped concepts |
-| NAACCR Procedure | Standard concepts, always map to self |
-| Permisssible Range | Non-standard without mapping |
-=== External relations ===
-__NAACCR Schema__ concepts have specific relations to precoordinated standard ICDO Condition concepts from [[documentation:vocabulary:icdo3|ICDO3]] concepts sourced from SEER. These relations indicate relation between neoplasm diagnoses and NAACCR schemas containing variables supporting further detalization of diagnoses and treatment history. They are intended to be used in extended ETL logic.
-^ Source vocabulary ^ Source concept_class_id ^ relationship_id ^ Target vocabulary ^ Target concept_class_id ^
-| NAACCR | NAACCR Schema | Schema to ICDO | ICDO3 | ICDO3 Condition |
-| NAACCR | NAACCR Proc Schema | Proc Schema to ICDO | ICDO3 | ICDO3 Condition |
-^ Reverse relations ^^^^^
-| ICDO3 | ICDO Condition | ICDO to Schema | NAACCR | NAACCR Schema |
-| ICDO3 | ICDO Condition | ICDO to Proc Schema | NAACCR | NAACCR Proc Schema |
