Michael Tuttle9for the American Thyroid Association Anaplastic Thyroid Cancer Guidelines TaskforceBackground:Anaplastic Thyroid cancer (ATC) is a rare but highly lethal form of Thyroid cancer. Rapid evaluationand establishment of treatment goals are imperative for optimum patient management and require a multi-disciplinary team approach. Here we present Guidelines for the management of ATC.
2 The development of theseguidelines was supported by the American Thyroid Association (ATA), which requested the authors, membersthe ATA Taskforce for ATC, to independently develop Guidelines for :Relevant literature was reviewed, including serial PubMed searches supplemented with additionalarticles. The quality and strength of recommendations were adapted from the Clinical Guidelines Committee ofthe American College of Physicians, which in turn was developed by the Grading of Recommendations As-sessment, Development and Evaluation :The Guidelines include the diagnosis, initial evaluation, establishment of treatment goals, approaches tolocoregional disease (surgery, radiotherapy, systemic therapy, supportive care during active therapy), ap-proaches to advanced/metastatic disease, palliative care options, surveillance and long-term monitoring, andethical issues including end of life.
3 The Guidelines include 65 :These are the first comprehensive Guidelines for ATC and provide recommendations for man-agement of this extremely aggressive malignancy. Patients with stage IVA/IVB resectable disease have the bestprognosis, particularly if a multimodal approach (surgery, radiation, systemic therapy) is used, and some stageIVB unresectable patients may respond to aggressive therapy. Patients with stage IVC disease should be con-sidered for a clinical trial or hospice/palliative care, depending upon their organization of these guidelinesis depicted inTable 1 and directs the reader to both text and the recom-mendations developed from the literature reviewed. Figure 1provides an illustrative overview of the initial management ofpatients suspected to have anaplastic Thyroid carcinoma (ATC),including accurate diagnosis, evaluation, and staging, followedpromptly by establishing goals of care desired by the malignancies are increasing in frequency and ac-count for of all cancers in the United States.

8 In the United States, ATC isresponsible for of all Thyroid cancers, while geographi-cally the prevalence ranges from to (median= )(1). In several countries the prevalence of ATC has decreaseddramatically, due in part to increased dietary iodine and bettermanagement of differentiated Thyroid cancer (DTC) (2,3).Unlike DTC, which is derived from follicular Thyroid cells,and medullary Thyroid cancer (MTC), which are frequentlycured or associated with prolonged survival, ATC patientshave a median survival of 5 months and a 20% 1-year survivalrate (1). All patients are classified by the American JointCommittee on Cancer (AJCC) TNM system as stage IV (A, B,or C) at presentation, and counseling and establishing amanagement plan must be accomplished quickly.
9 While allthyroid cancer patients require a multidisciplinary team ofspecialists for optimal care, the coordinating physician isfrequently an endocrinologist who has established a long-standing relationship with the patient who has DTC or contrast, the sudden onset and explosive course of ATCnecessitates immediate involvement by surgeons, radiationand medical oncologists, and palliative care American Thyroid Association (ATA) has a history ofsupporting the development of Guidelines for the care of pa-tients with Thyroid disease.* This includes several guidelinesfor management of DTC (4 6) and recent first MTC Guidelines (7). No such ATA Guidelines exist for management of patientswith ATC. The Latin American Thyroid Society has alsopublished recommendations for DTC management (8).
10 Otherorganizations have made recommendations for patients withATC. The National Comprehensive Cancer Network devotes37 pages to treating and following DTC patients but onlythree pages for ATC (9). The American Association of ClinicalEndocrinologists Guidelines for Thyroid cancer discuss ATCmanagement in less than one page (10).PageAPPROACHES TO ADVANCED METASTATICDISEASE (STAGE IVC)1123 Defining therapeutic goals, expected/possible adverseevents, appropriate expectations, and limits of care1123 Timing of systemic therapies1123&Recommendation 421123 Approaches to systemic disease (cytotoxic)1123 Taxanes1123 Anthracyclines and platins1123 First-line therapy1124 Second-line or salvage therapy1124 Approaches to systemic disease (novel orinvestigational)1124&Recommendation 431125&Recommendation 441125&Recommendation 451125&Recommendation 461125 Systemic therapy: what is next?
