Objectives: BRAFV600E- anaplastic thyroid cancers (ATCs) show remarkable responses to dabrafenib and trametinib (dab/tram) an effect that may be in part immune-mediated. Murine BRAFV600E-ATCs regress upon BRAF inhibition. We find that recurrences are frequent and associated with loss of Mhc class II (MhcII) expression. Our goal was to investigate the mechanisms of loss of antigen presentation by tumor cells and whether this contributes to disease recurren...

Context: Anaplastic (ATC) thyroid carcinoma is an orphan disease accounting for about 2% of all malignant thyroid tumors. ATC confers a dismal prognosis and standard treatment is not established.Objective: To describe the epidemiology, current treatment regimens and outcome of ATC, to identify clinical prognostic markers and treatment factors associated with improved prognosis. To establish a consensus treatment schedule.Design: Re...
