Primary current-line option

Standard plan

★ DEFAULT

Indication

IND-GBM-NEWLY-DIAGNOSED-STUPP

Regimen

Stupp protocol — Temozolomide concurrent + adjuvant

Drugs + NSZU

Temozolomide (DRUG-TEMOZOLOMIDE) Concurrent: 75 mg/m² PO daily during RT 6 weeks; Adjuvant: 150 mg/m² PO days 1-5 cycle 1 (escalate to 200 if tolerated) every 28 days × 6 cycles · Concurrent daily × 42 days then 4-week break then adjuvant cycles 1-6 · PO ✓ NSZU covered

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.

Other current-line alternatives (2 tracks)

Same treatment line; review when biomarker, access, contraindication, or patient-context assumptions change.

Standard plan

Indication

IND-GBM-NEWLY-DIAGNOSED-ELDERLY-TMZ

Regimen

Temozolomide monotherapy

Drugs + NSZU

Temozolomide (DRUG-TEMOZOLOMIDE) ✓ NSZU covered

Reason

Current-line alternative presented for HCP consideration

Standard plan

Indication: IND-GBM-NEWLY-DIAGNOSED-ELDERLY-HYPORT
Regimen: Hypofractionated radiotherapy for GBM
Reason: Current-line alternative presented for HCP consideration

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. RF-GBM-INTRACRANIAL-PRESSURE-EMERGENCY
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). RF-GBM-TRANSFORMATION-PROGRESSION

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

Timeline
