Ursprung der Roten Flagge

Begriffsbestimmung	Baseline organ dysfunction precluding standard PCV (procarbazine / CCNU / vincristine) or temozolomide adjuvant in low-grade glioma: CrCl <30 mL/min (CCNU / temozolomide dose adjustment), bilirubin >3× ULN (CCNU / vincristine hepatic clearance), severe cytopenias (ANC <1.5, platelets <100), or DLCO <60% (CCNU pulmonary fibrosis signal at cumulative doses).
Klinische Richtung	Eskalation

Anmerkungen

RTOG 9802 established RT + PCV as standard for high-risk LGG; PCV is marrow-suppressive (cumulative thrombocytopenia from CCNU is a leading cause of treatment discontinuation). Temozolomide is better-tolerated alternative widely substituted in practice (CATNON, EORTC 22033 data in IDH-mut anaplastic gliomas) — also marrow-suppressive but more predictable. CrCl <30: temozolomide dose reduce 25%, CCNU contra- indicated. Cytopenias at baseline frequently reflect prior RT — defer systemic therapy until recovery. Vorasidenib (IDH-mut LGG, INDIGO trial) is now an option with more favorable toxicity profile — consider in organ-dysfunction setting if IDH-mut.
