[Molecular diagnostics enable targeted therapies for anaplastic and poorly differentiated thyroid cancer].

Abstract

Anaplastic and poorly differentiated thyroid cancer (ATC, PDTC) are rare and highly aggressive tumors that historically have been associated with a short life expectancy and low chance of cure. Molecular pathology and the introduction of highly effective targeted drugs have revolutionized the possibilities of management of patients with ATC and PDTC, with BRAF and MEK inhibitors as the most prominent example. Here we provide updated recommendations regarding diagnostics and management, including primary surgical management and targeted therapies based on specific molecular pathological findings.
