Assessment

ELN 2022 ELN 2017

Required data at a glance

Core marrow/disease assessment: post-treatment blast assessment, aspirate adequacy, circulating blasts, extramedullary disease, and Auer rods at the response-assessment timepoint.
Blood counts: ANC and platelets are needed to distinguish CR, CRh, CRi, and PR. MLFS can still be assigned without count recovery.
Conditional fields: assessment date is required for pasted/CSV bloods; baseline BM blasts are only required to assess PR; trephine blasts are used when aspirate morphology is inadequate or unavailable.

Choosing “Not stated” is allowed where clinically true, but may return Assessment incomplete rather than assuming absence.

Assessment date Required for paste/CSV Used to select eligible blood counts within the configured 7-day window. Blood count window Required for paste/CSV Default includes the assessment date and the preceding 7 calendar days. Manual entry bypasses window selection.

Marrow

Baseline BM blasts (%) PR only Only needed if post-treatment blasts are in the PR range. Post-treatment BM blasts (%) Required Primary marrow response value when aspirate morphology is adequate.

Aspirate adequacy Required Trephine blasts by IHC (%) If aspirate inadequate Used as fallback when aspirate blast percentage is missing or not evaluable.

Trephine adequacy If trephine used Extramedullary disease at response assessment Required

Circulating blasts at response assessment Required Auer rods at response assessment Required Exclusionary in ELN 2017; documented but not exclusionary in ELN 2022.
