Abstract
PURPOSE OF REVIEW: Since the discovery, in 1994, of recurrent codeletion of chromosome regions 1p36/19q13 in oligodendrogliomas, genetics has accomplished significant advances improving our knowledge in biology of this tumor type and our clinical management of oligodendroglioma patients. Indeed, 1p36/19q13 has been shown successively to predict increased chemosensitivity and better prognosis, to be associated with frontal location in brain and classic oligodendroglioma morphology, to be mutually exclusive with high-level gene amplification, to be actually whole chromosome arms 1p/19q codeletion, to mediate a t(1;19)(q10;p10) and to be associated with IDH mutations. More recently, pivotal studies, using high-throughput approaches, have provided significant novel insights in the molecular oncogenesis of oligodendrogliomas. RECENT FINDINGS: Capicua homolog (Drosophila) (CIC) and Far Upstream element Binding Protein 1 (FUBP1) have been shown to be frequently mutated in 70 and 40% of 1p/19q codeleted oligodendrogliomas, respectively. The biological and clinical significance of these mutations remains unsettled. Additional recent studies have also demonstrated that 1p/19q codeleted oligodendrogliomas exhibit a proneural transcriptomic profile including overexpression of internexin alpha, a neuronal intermediate filament. Finally, 1p/19q codeleted and IDH-mutated tumors have been shown to be hypermethylated, suggesting a strong link between these both molecular alterations detected in the subgroup of oligodendrogliomas with better prognosis. SUMMARY: Next-generation molecular biology technologies have recently identified recurrent CIC and FUBP1 point mutations in 1p/19q codeleted and IDH-mutated oligodendrogliomas. Their clinical and biological values are under investigation.

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.
