A Quality Improvement Initiative: Routine End of Therapy Bone Marrow Aspirates in Pediatric B cell Acute Lymphoblastic Leukemia in Oman
Bibliographic record
Abstract
The utility of end of treatment bone marrow aspirates (EOTBMA) and cerebral spinal fluid analysis (EOTCSF) in B-cell acute lymphoblastic leukemia (B-ALL) is unclear. A retrospective review, n=50, B-ALL age 1-18 years at diagnosis, having EOTBMA and EOTCSF, at a single institution 2010-2018 was conducted. No bone marrow or CNS relapse was detected by EOTBMA or EOTCSF. 4/50 (8.0%) patients relapsed at a median of 2.5 years (range 0.9-4.5 years). Consensus to abandon routine EOTBMA occurred by presenting results to faculty. Our data supports absence of utility of routine EOTBMAs and EOTCSF in pediatric B-ALL. Disseminating local data facilitated consensus in implementing best practice.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
