Use of G‐CSF in Matched Sibling Donor Pediatric Allogeneic Transplantation: A Consensus Statement from the Children's Oncology Group (COG) Transplant Discipline Committee and Pediatric Blood and Marrow Transplant Consortium (PBMTC) Executive Committee
Bibliographic record
Abstract
Preliminary studies indicate that G-CSF-primed marrow harvesting may result in a graft with increased mononuclear cells collected, increased CD34(+) stem and progenitor cell dose and a potential for more rapid engraftment. Increased cell dose plus other potential positive effects of G-CSF priming have resulted in improved survival in non-randomized preliminary studies. These benefits may be available without the increased risk of chronic graft versus host disease (GVHD) that is experienced with allogeneic peripheral blood stem cell (PBSC) transplant. A phase III Children's Oncology Group (COG)/Pediatric Blood and Marrow Transplant Consortium (PBMTC) trial comparing G-CSF-primed marrow to standard marrow has been proposed. This document reviews background studies of G-CSF-primed marrow and addresses benefits and risks of G-CSF administration to normal pediatric donors. We conclude that the approach is promising and warrants further study. Risks of G-CSF to the donor are minimal and benefits to both donor and recipient may occur.

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.
