Primary CNS Tumors and Leptomeningeal, Disseminated and/or Multicentric Disease in Children Treated in Phase II Studies with Antineoplastons A10 and AS2-1
Bibliographic record
Abstract
<p class="cco-body"><span lang="EN-GB">It is estimated that as many as 30% of patients with primary CNS tumors have leptomeningeal, disseminated, and/or multicentric disease (LDM). These patients respond poorly to conventional therapy. Fifty-seven children with LDM (median age of 7.1 years) were treated in multiple prospective phase II clinical studies of high- and low-grade primary CNS tumors with Antineoplastons A10 and AS2-1 (ANP). Their inclusion in this analysis was based on MRI imaging. Patients with glioblastoma were excluded. The patients received ANP therapy 6 times daily; A10: 8.77 g/kg/d; AS2-1: 0.35 g/kg/d. The response to ANP was monitored by MRIs every 8 weeks. Patients evaluable for efficacy (<em>N </em>= 40) received 12 or more weeks of ANP or developed progressive disease (PD) before 12 weeks. 10 patients (17.5%) achieved an objective response (OR) with 4 (7%) achieving a complete response (CR) and 6 (10.5%) had a partial response (PR). Stable disease (SD) was maintained in 7 patients (12.3%) and PD developed in 23 patients (40.4%). Survival analysis of the 57 children showed 2- and 5-year overall survival (OS) were both 28% while 10- and 15-year OS were both 26%. One of the patients achieving an OR had atypical teratoid/rhabdoid tumor (AT/RT) while nine had low-grade gliomas (LGGs). Grade 3 and 4 toxicities included hypokalemia (14.0%); fatigue, anemia, hypernatremia and leukopenia (3.5% each); diarrhea, hypertension, joint pain, thrombocytopenia, and somnolence (1.8% each). These findings suggest the need for a single-arm, phase II study of ANP in children with LDM.</span></p>

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
