  * The group discussed SQL showing how to map ICDO Site/Histology combinations to pre-coordinated Condition concepts.

  * The group discussed SQL showing how to find all Site/Histology combinations containing a particular ICDO site or histology.

  * It was announced that ICDO is currently already implemented within Athena and folks should try mapping their ICDO data.

  * The group discussed the plan to adopt NAACCR as OMOPS's standard vocabulary of cancer diagnosis modifiers and the plant to transition NAACCR from a standard vocabulary to source vocabulary by mapping NAACCR to the Nebraska Lexicon.

  * Concern was expressed regarding the timeline for when the Nebraska Lexicon would be completed.

  * There was consensus in the group that the OMOP community needs to standardize the representation of cancer  diagnosis modifiers.  Some members of the group might take a swipe at recommending cancer diagnosis modifiers ahead of the Nebraska Lexicon completion date.

  * It was announced that the Hemonc.org drug regimen ontology has been released within Athena.

  * The group discussed the current state of the Hemonc.org vocabulary.  Regimens and regimen components mapped to RxNorm ingredients.  Plus a better drug oncology classification system.

  * The group asked about the future possibility of including regimen dosing, cycles and indications.  Dmytry informed the group that these items would be part of future releases.
