Abstract

fetched live from OpenAlex

The concurrence of acute lymphoblastic leukemia (ALL) and an asymptomatic juvenile pilocytic astrocytoma is described. A 6-year-old boy without clinical evidence of neurofibromatosis had a juvenile pilocytic astrocytoma diagnosed on radiologic examination and before treatment of acute pre-B cell lymphoblastic leukemia. The patient has had a partial resection of the astrocytoma and is 9 months into treatment of his ALL, which is in complete remission. p53 gene mutation was not identified in this patient. The concurrent diagnosis before treatment of ALL and juvenile pilocytic astrocytoma, the latter normally an indolent tumor, suggests that some cases of astrocytoma previously ascribed to radiotherapy or other treatment may in fact be caused by other factors.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
