Definición	Age ≥75 with ECOG ≥2 or ≥2 comorbidities — lenvatinib full-dose (24 mg) poorly tolerated; consider lenvatinib 14 mg starting dose (Brose et al subgroup), selective RET / NTRK inhibitor monotherapy if fusion+, or watchful waiting if asymptomatic indolent metastatic disease (most PTC indolent — frail elderly often die with rather than from disease).

Notas

PTC is the most indolent thyroid malignancy; for elderly with metastatic but asymptomatic disease, watchful waiting with serial thyroglobulin + imaging is appropriate (especially if doubling time >12 mo). Lenvatinib starting at 14 mg (vs 24 mg standard) tested in Study 211 — PFS comparable, lower hypertension / fatigue / proteinuria burden in elderly. Selpercatinib / pralsetinib (RET+) and larotrectinib / entrectinib (NTRK+) better tolerated than multikinase — preferred in frail elderly when biomarker-positive. Geriatric assessment (G8) ≥70 recommended before TKI initiation. Most PTC patients in this category will benefit more from symptom-focused care + low-dose TKI than full-dose induction.
