Abstract
Longer and more intensive postinduction intensification (PII) improved the outcome of children and adolescents with "higher risk" acute lymphoblastic leukemia (ALL) and a slow marrow response to induction therapy. In the Children's Cancer Group study (CCG-1961), we tested longer versus more intensive PII, using a 2 x 2 factorial design for children with higher risk ALL and a rapid marrow response to induction therapy. Between November 1996 and May 2002, 2078 children and adolescents with newly diagnosed ALL (1 to 9 years old with white blood count 50 000/mm3 or more, or 10 years of age or older with any white blood count) were enrolled. After induction, 1299 patients with marrow blasts less than or equal to 25% on day 7 of induction (rapid early responders) were randomized to standard or longer duration (n = 651 + 648) and standard or increased intensity (n = 649 + 650) PII. Stronger intensity PII improved event-free survival (81% vs 72%, P < .001) and survival (89% vs 83%, P = .003) at 5 years. Differences were most apparent after 2 years from diagnosis. Longer duration PII provided no benefit. Stronger intensity but not prolonged duration PII improved outcome for patients with higher-risk ALL. This study is registered at http://clinicaltrials.gov as NCT00002812.

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
