ESCAT: clinical review pendingBIO-TERTTERT promoter mutation (C228T or C250T) — WHO CNS tumor classification context: GBM (IDH-wild-type; required for molecular diagnosis), oligodendroglioma (IDH-mutant + 1p/19q co-deletion + TERT = canonical)IIB
Standard care
  • SRC-NCCN-CNS-2025: Level Category 1 (Supports, Poor Outcome)
  • SRC-EANO-GBM-2024: Level A (Supports, Poor Outcome)
TERT promoter mutations are central to WHO CNS tumor classification (2021 5th edition): (1) GBM (IDH-wildtype, WHO grade 4): TERT promoter mutation is one of three molecular defining features (together with EGFR amplification and chromosome +7/-10 copy number changes). An IDH-wildtype diffuse astrocytoma with any of these features meets criteria for molecular GBM diagnosis regardless of histologic grade. TERT alone: ~70–80% of GBM. TERT mutation identifies the most aggressive tumor biology within IDH-wildtype astrocytomas. No TERT-directed therapy available. (2) Oligodendroglioma (IDH-mutant, 1p/19q co-deleted): TERT promoter mutation is present in ~70% and is part of the canonical molecular definition. TERT testing is used to confirm oligodendroglioma classification (IDH + 1p/19q + TERT triple positive). (3) IDH-mutant astrocytoma (grade 2–4): TERT promoter mutation is less common (~20%) and associated with worse prognosis within IDH-mutant tumors; CDKN2A/B homozygous deletion is the main grade 4 determinant in IDH-mutant astrocytoma. Standard treatment for GBM is unchanged by TERT status: Stupp protocol (RT + temozolomide, followed by temozolomide maintenance). MGMT promoter methylation — not TERT — determines temozolomide sensitivity. ESCAT IIB: TERT is a diagnostic molecular classifier in glioma with strong prognostic significance but no actionable therapeutic target.Stupp protocol: RT 60 Gy/30 fr + temozolomide 75 mg/m² PO QD during RT, then temozolomide 150–200 mg/m² PO days 1–5 q28d × 6 cycles (MGMT-guided; not TERT-guided)

Reason
Provisional current-line default from ALGO-GBM-NEWLY-DIAGNOSED-1L: step 1 did not select a treatment branch. IDH-mutant glioma grade 4: not GBM per WHO 2021. Manage as astrocytoma IDH-mutant (vorasidenib INDIGO). Separate disease pathway.

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track
  • Symptomatic raised intracranial pressure / mass effect in glioblastoma: declining GCS, new focal deficit, papilledema, midline shift on imaging, or seizure cluster. Mandates immediate neurosurgical / corticosteroid intervention BEFORE oncologic systemic therapy.
    Mass effect emergency — dexamethasone 8-16 mg IV stat, neurosurgical consult for resection / debulking / VP shunt. Anti-epileptics for seizure cluster (levetiracetam preferred — no enzyme induction vs older AEDs that interfere with TMZ…

  • Glioblastoma progression on or after first-line Stupp regimen: MRI evidence of true progression (RANO criteria — distinguished from pseudoprogression by serial imaging / advanced techniques), early recurrence <6 months post-RT (often pseudoprogression — repeat MRI at 4-8 weeks before re-treatment decision), or distant new lesion. Routes from upfront Stupp to recurrent-GBM algorithm (re-resection + bevacizumab / TTF / regorafenib / lomustine / re-irradiation).
    Pseudoprogression occurs in ~30% post-Stupp at 3 mo MRI — does not represent true tumor growth (treatment-related inflammation / radiation effect); RANO criteria require either second confirmatory MRI or outside-RT-field new disease…

CONTRA-AGGRESSIVE

Hard contraindications to escalation

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-GBM-NEWLY-DIAGNOSED-STUPP)
  • Do NOT delay starting RT beyond 6 weeks post-resection
  • Do NOT skip MGMT testing — defines elderly (≥70) regimen choice
  • Do NOT skip PJP prophylaxis (universal lymphopenia → opportunistic infection)
  • Do NOT use enzyme-inducing AEDs (phenytoin, carbamazepine) — accelerate TMZ clearance; use levetiracetam
Standard plan (IND-GBM-NEWLY-DIAGNOSED-ELDERLY-TMZ)
  • Do NOT use TMZ alone in MGMT-unmethylated GBM ≥70 — minimal benefit; prefer hypofractionated RT
  • Do NOT use full Stupp (60 Gy/30 fx) in patients ≥70 or KPS <60 — excessive toxicity
  • Do NOT skip MGMT testing before choosing TMZ vs RT — this is the key biomarker in elderly
  • Do NOT skip PJP prophylaxis (co-trimoxazole) — lymphopenia risk applies to TMZ mono too
Standard plan (IND-GBM-NEWLY-DIAGNOSED-ELDERLY-HYPORT)
  • Do NOT use full Stupp 60 Gy/30 fx in patients ≥70 or KPS <60 — unacceptable toxicity in elderly
  • Do NOT omit TMZ without first checking MGMT status — methylated patients benefit significantly
  • Do NOT skip MGMT testing — drives concurrent TMZ decision
  • Do NOT start RT without post-resection MRI (within 48h of surgery)
  • Do NOT delay RT beyond 6 weeks post-surgery

#OwnerTopicAction
1molecular_geneticistBiomarker status BLOCKINGWhat is the status of MGMT promoter methylation status (BIO-MGMT-METHYLATION)? It is required by track(s): IND-GBM-NEWLY-DIAGNOSED-STUPP, IND-GBM-NEWLY-DIAGNOSED-ELDERLY-TMZ. Expected value: MGMT methylation status (methylated / unmethylated) — required input; methylated patients have substantially better TMZ response (~21.7 mo vs ~12.7 mo OS) but Stupp protocol applies regardless.
