Definição	Baseline organ dysfunction precluding standard lenvatinib / sorafenib multikinase inhibitor for RAI-refractory PTC or affecting selective TKI dosing: LVEF <50% (lenvatinib hypertension + cardiac dysfunction), CrCl <30 mL/min (TKI dose adjustment), bilirubin >3× ULN (sorafenib / lenvatinib hepatic clearance), QTc >480 ms (TKI-class QT prolongation), uncontrolled hypertension, or prior fistula / GI perforation (lenvatinib / sorafenib FDA boxed-warning class).

Notas

Lenvatinib carries severe hypertension (~70% any grade), proteinuria, hand-foot, and rare fistula / GI perforation (FDA boxed warning class). Sorafenib similar profile + hand-foot more pronounced. Selective RET (selpercatinib, pralsetinib) and NTRK (larotrectinib, entrectinib) inhibitors better-tolerated alternatives — preferred when fusion+. Dabrafenib + trametinib for BRAF-mut RAI-refractory PTC has lower hypertension burden than lenvatinib but adds pyrexia + cardiac monitoring. Most PTC patients are LVEF-normal at presentation but develop cardiac dysfunction on chronic multikinase TKI exposure — baseline ECHO + 3-monthly during therapy.
