Anaplastic Thyroid Cancer

Initial Staging & Treatment Planning

Management Recommendations

1. Multidisciplinary Care

ATC is a unique thyroid malignancy that requires expert care by a team of multidisciplinary specialists who are experienced in ATC management. It is imperative that comprehensive multidisciplinary engagement be achieved prior to defining the goals of care and discussing treatment options with the patient.​1–4​

It is important that patients have appropriate cognitive ability to understand and be able to consent to specific medical decisions that they are required to make. If there is any question as to the patient’s capabilities, then mental health assessment should be rapidly obtained along with input from individual(s) trained in medical ethics to assist in establishing a plan of care.​1​

2. Initial Staging of Patients with ATC Diagnosis

In the expedited evaluation of patients diagnosed with ATC, it is vital to determine the locoregional extent of disease as well as to identify the presence of spread outside the neck. Cross sectional imaging using contrast enhanced CT examinations (or MRI) of the neck, chest, abdomen and pelvis should be performed. FDG PET CT can provide useful information in staging. When indicated, an MRI of the brain should be considered.​1–4​

Other Diagnostic Studies

  • CBC; a white cell count (> 10,000 is poor prognostic finding).​1–4​
  • Liver function tests, BUN, creatinine, and glucose.​1​
  • TSH, free thyroxine, thyroglobulin, and thyroglobulin antibody.​1​

A. Expedited Initial Evaluation is Essential

Due to the rapidity of the growth of ATC, it is essential that a coordinated and expeditious scheduling of appointments for scans and multidisciplinary assessment be achieved.​1,2,4​

The performance of cytologic or pathologic assessment of lesions outside the neck for possible metastatic spread provides important information for the overall plan of care. Some guidelines advocate that these biopsies be performed, however, not allowing such to delay the initiation of primary therapy.​1​ Other guidelines favor initial assessment of resectability prior to consideration of systemic therapy.​3,4​

Due to the invasive nature of ATC, treatment planning and, in particular surgical assessment, depends on an understanding of each patient’s vocal cord function and potential tracheal invasion. Over time, this may require repeat assessment during therapy as indicated by the patient’s evolving clinical symptoms.​1–4​
