Abstract
Abstract Background Children’s Oncology Group ACNS0333 treated atypical teratoid/rhabdoid tumor (ATRT) with surgery, chemotherapy (induction and consolidation) and radiation therapy (RT). M0 had focal RT and M+ had physician-selected focal RT or craniospinal (CSI). Methods Forty patients (29 M0, 11 M+) received RT. Pre-RT chemotherapy response was complete, partial, or stable disease. RT timing (age/stage-based) was pre-consolidation (RT-first) or post-consolidation (consolidation-first). Event-free survival (RT-EFS), overall survival (RT-OS), and cumulative incidence of local relapse (CILR) or distant relapse (RT-CIDR) were calculated. Analyses included log-rank tests and relative hazard rates with 95% confidence intervals to estimate proportional hazards regression. Results Four-year RT-EFS was 56.8% and 4-year RT-OS was 58.8% focal RT: 34 patients, CSI: 6 patients). A trend for superior RT-EFS for M+ compared to M0 (P = .0625, RHR 0.26; 95% CI 0.06-1.18) was shown. RT-EFS was improved for consolidation-first compared to RT-first timing (P = .037, RHR 0.43; 95% CI 0.13-1.37). Pre-RT chemotherapy response was associated with improved RT-EFS (P = .031) and RT-OS (P = .0069). Four-year RT-CILR was 7.84%; no differences in RT-CILR were shown for higher primary RT dose (≥5400 cGy, P = .38) or gross total resection (P = .80). 4-year RT-CIDR was 27.8% for M0 and 9.1% for M+ patients (P = .22). M+ had CSI (n = 6) or focal RT (n = 5). Fatal necrosis potentially-attributable to RT occurred in 3 RT-first patients (occuring either 1.6, 4.6, or 16.2 months post-treatment). Conclusions RT with intensive systemic therapy showed promising survival outcomes and effective primary disease control in ATRT. Sequencing RT prior to myeloblative chemotherapy, rather than post-consolidation, may be associated with increased risk of fatal radionecrosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
