Etoposide, vincristine, and cyclosporin A with standard‐dose radiation therapy in newly diagnosed diffuse intrinsic brainstem gliomas: A pediatric oncology group phase I study
Bibliographic record
Abstract
BACKGROUND: Brainstem gliomas (BSGs) are resistant to all therapy. Based on their imaging characteristics, we postulated that inhibition of P-glycoprotein (P-gp) associated with endothelial cells of the blood-brain barrier might enhance penetration of xenobiotic antineoplastics. PROCEDURE: Seven patients were enrolled in a Phase I study of etoposide, continuous infusion cyclosporine A given with and escalating doses of vincristine and concomitant standard-dose irradiation. RESULTS: Six patients were entered at the first level and one at the second. Closure of the study was mandated by dose-limiting neurotoxicity, consisting of seizures associated with white-matter changes, and alteration of consciousness with bulbar signs. One patient had tumor necrosis at 6 weeks, suggesting some tumor effect. Median survival for the group was 11 months, and for the patients who completed more than 1 month of therapy it was 11 months. CONCLUSION: This regimen proved excessively toxic.

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.
