Origine du drapeau rouge

Définition	Frailty profile precluding standard FL combination immunochemo (BR / R-CHOP / G-B / R-Len): ECOG ≥3, OR (age ≥80 with any moderate comorbidity), OR composite frailty (age ≥75 + Charlson ≥3 + albumin <3.5). Triggers de-escalation to rituximab monotherapy or rituximab + chlorambucil (well-tolerated, palliative-curative balance).
Direction clinique	désescalade
Catégorie	âge de fragilité

Notes

FL is indolent and frequently watch-and-wait appropriate. When treatment is required (per GELF criteria), rituximab monotherapy weekly x4 then maintenance — well-tolerated, response durable in low-burden disease, and can be repeated at progression. Rituximab + chlorambucil oral schedule (StiL NHL2) reasonable for mid-frailty. Avoid bendamustine in elderly with active infection / prior PJP / hypogamma — opportunistic infection risk substantial. Lenalidomide in frail elderly causes cytopenias / fatigue — start reduced-dose (10 mg) and titrate.
