DefiniçãoBaseline organ dysfunction precluding standard cisplatin / paclitaxel / doxorubicin chemoradiation or affecting BRAF-MEK-inhibitor dosing in ATC: CrCl <30 mL/min (cisplatin contraindicated), LVEF <50% (doxorubicin contraindicated; trametinib cardiac monitoring), bilirubin >3× ULN (BRAFi/MEKi hepatic clearance), QTc >480 ms (dabrafenib QT signal), or compromised airway from tumor (tracheostomy or stent required before systemic therapy initiation).

Notas

ATC patients commonly present with rapid neck mass + airway compromise — emergency airway management (tracheostomy / endotracheal stent) is the gating step before any systemic therapy. Cisplatin-paclitaxel weekly with concurrent IMRT is the cytotoxic standard in BRAF-wild- type ATC; CrCl <30 forces switch to carboplatin or omit platinum. Dabrafenib + trametinib better tolerated than cytotoxic in BRAF-mutant ATC — preferred for organ-dysfunction scenarios. LVEF <50% is gating for doxorubicin-containing regimens (DHA-BCG historical). Trametinib carries LVEF decline risk (~5% Gr3+) — baseline ECHO + serial. Critical severity reflects the disease's narrow therapeutic window.
