Extracranial Relapse of an Anaplastic Oligodendroglioma in an Adolescent: Case Report and Review of the Literature
Bibliographic record
Abstract
Oligodendroglioma is an uncommon childhood tumor and is more chemosensitive than other malignant glial neoplasms. Treatment involves gross total resection, and if anaplastic, radiation and chemotherapy. Distinct genetic alterations are associated with improved prognosis. We report a child with a low-grade oligodendroglioma that recurred as a high-grade oligodendroglioma and ultimately as extraneural systemic relapse. It was initially responsive to temozolomide, cyclophosphamide, etoposide, and carboplatin, perhaps predicted by combined loss of heterozygosity at 1p and 19q. This chemotherapy may be promising in treating malignant oligodendroglioma. However, he succumbed to progressive systemic disease. Positron emission spectroscopy scan was useful in sequentially assessing his disease.
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.

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.
