(2020)), it contains 1'301 oncological notes, with 15'978 annotations linked to an ICD-O-3.1 morphology code. Additionally, 15’457 of them are linked to a SNOMED-CT code. DISTEMIST-FR: Originally from DISTEMIST's training set (Miranda-Escalada et al. (2022)), it contains 750 clinical cases, with 8'059 annotations, with 5'132 of them linked to a SNOMED-CT code.
