Objectives:
To describe the first reported use of neoadjuvant dabrafenib and trametinib specifically to permit organ conservation surgery in locally advanced recurrent differentiated thyroid carcinoma.
Patients And Methods:
A patient presented with locally recurrent, radioiodide-resistant DTC with a BRAF V600E mutation invading the laryngotrachea. Definitive treatment would require a total laryngectomy. She was offered neoadjuvant dabrafenib and trametinib prior to surgery.
Results:
A significant radiographic response permitted partial laryngectomy, enabling preservation of voice, early resumption of oral feeding, and avoidance of permanent tracheostomy. At 9 months, she remained free of disease.
Conclusion:
Neoadjuvant tyrosine kinase inhibitor treatment prior to definitive surgery for locally-invasive recurrent DTC is a potential approach that may limit the degree of surgery and associated morbidity.
