Laryngotracheal Resection After B-Raf Proto-oncogene Inhibition for Anaplastic Thyroid Carcinoma

Ann Thorac Surg. 2023 May;115(5):e117-e120. doi: 10.1016/j.athoracsur.2022.04.034. Epub 2022 Apr 30.


Anaplastic thyroid carcinoma is a rare but aggressive neoplasm that often presents as advanced inoperable disease. Patients with B-Raf proto-oncogene (BRAF) v600e mutated anaplastic thyroid carcinoma who receive neoadjuvant dabrafenib/trametinib have improved rates of microscopically margin-negative resection and durable locoregional control. However this has not been evaluated in the setting of tracheal resection and primary reconstruction. Here we demonstrate the safety and efficacy of laryngotracheal resection and reconstruction after dabrafenib/trametinib for locoregionally advanced BRAF v600e mutated anaplastic thyroid carcinoma.
