Origine du drapeau rouge

Définition	Age ≥75 with ECOG ≥2 or ≥2 comorbidities — vandetanib / cabozantinib multikinase inhibitors poorly tolerated (severe diarrhea, hand-foot, hypertension, fatigue); selpercatinib / pralsetinib better-tolerated alternatives but still require dose adjustment; for asymptomatic indolent MTC, watchful waiting with calcitonin / CEA monitoring is appropriate.

Notes

MTC is often indolent — watchful waiting with calcitonin doubling time monitoring is appropriate for slow-progressing asymptomatic disease in elderly (ATA recommendation). Cabozantinib (EXAM trial) and vandetanib (ZETA) have meaningful diarrhea + hypertension burden; dose reductions to 60 mg / 200 mg respectively common in elderly. Selpercatinib LIBRETTO-531 demonstrated superior tolerability vs vandetanib — preferred 1L when RET-mutant. Geriatric assessment (G8) ≥70 recommended before TKI initiation. ¹⁷⁷Lu-DOTATATE PRRT is generally well-tolerated in elderly with SSTR+ disease and limited acute toxicity profile.
