The utility of end‐of‐treatment bone marrow aspirates in pediatric acute lymphoblastic leukemia: A quality improvement project
Bibliographic record
Abstract
We reviewed the use, results and costs of end-of-treatment bone marrow aspirates (EOTBMAs) performed locally in patients diagnosed with ALL between 2000 and 2005. Of 193 patients, 188(97%) received EOTBMAs. Though 15/188(8.0%) patients experienced relapse at a median time of 1.1 years (range 0.1-4 years), no sign of relapse was detected on any EOTBMA. After communication of results to clinical staff, only 2/17 (12%) of patients with ALL finishing treatment in the subsequent 5 months received an EOTBMA (P < 0.0001). Our results confirm the futility of EOTBMAs in a large contemporary cohort. Disseminating local results may help ensure adherence to best practices.

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.
