Origine du drapeau rouge

Définition	Active or latent infection requiring resolution / prophylaxis before initiating PCV or temozolomide adjuvant for low-grade glioma: HBsAg-positive (HBV reactivation on cytotoxic chemotherapy plus steroid co-therapy common with brain edema), anti-HBc-positive (occult HBV), HIV-positive (ART coordination + Pneumocystis prophylaxis), or active TB. Steroid-induced reactivation amplifies risk.
Direction clinique	en attente
Catégorie	dépistage des infections

Notes

Brain-tumor patients commonly receive concurrent dexamethasone for edema — chronic steroid exposure compounds HBV-reactivation risk on temozolomide / PCV. HBsAg+ → entecavir / tenofovir prophylaxis pre- chemo through 12 mo post. HIV+ glioma patients require Pneumocystis prophylaxis on dex + alkylator combo (lymphopenia is profound). Active TB: complete anti-TB before chemoradiotherapy when feasible; isoniazid hepatotoxicity + temozolomide hepatic clearance create monitoring burden. Surfaces hold via parallel pre-treatment workup rather than indication switch.
