Hey there! I downloaded a vocabulary from athena for only NCI thesaurus, and the result was only about 2500 concepts. But I downloaded the thesaurus directly from the NCI and it contains about 166k concepts. How do I go about requesting that the NCI thesaurus be updated in OMOP? Thanks!
Currently, OMOP NCIt vocabulary intends to hold the terms only pertaining to cancer staging and to a small extent, protein variants. If you need all the NCIt terms to be present in OMOP vocabulary, normally you would need to provide use cases.
