Stage 1 concept_ids using a query

How can I the get all the Stage 1 concept_ids without a concept set? Stage 1 is in the context of cancer. I’d like to get the concept_ids dynamically with a query without hard coding concept id numbers.

@agolozar Do you happen to know?

Stage 1 and all its descendant. It gives you any kind of Stage 1 or Stage I. If you want to set the staging system (AJCC, 6th, 7th, 8th, COG, Ann Arbor, FIGO etc.) go one down through “Subsumes” and take those descendants.

@Christian_Reich this just what I needed. Thank you.
