The document includes recommendations regarding initial evaluation of thyroid nodules, clinical and ultrasound criteria for fine-needle aspiration biopsy, initial management of thyroid cancer including staging and risk assessment, surgical management, radioiodine remnant ablation, and levothyroxine therapy, short-term and long-term follow-up strategies, and management of recurrent and metastatic disease. The objective of this consensus is to inform clinicians, patients, researchers, and health policy makers about the best strategies (and their limitations) relating to the diagnosis and treatment of differentiated thyroid cancer.

Incidental diagnosis of PTMC is frequent in a high prevalence of goiter area. PTMC shows a variable degree of aggressiveness. Management protocols should be based on patient- and tumor-related prognostic factors, as for larger tumors.

LA is a well-tolerated outpatient procedure that results in a rapid cytoreduction of cervical nodal metastases of PTC. Mini-invasive procedures may be used in lieu of surgery as an adjunctive therapy for small-burden local/regional disease recurrence. They are occasionally associated with an anatomical or biochemical cure, but long-term follow-up or controlled trials are needed.

In recent years, 2-[ 18 F]-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (FDG-PET/CT) has emerged as an important tool for the postoperative management of patients with differentiated thyroid cancer (DTC) and it is widely used in selected clinical situations. The most valuable role that FDG-PET/CT plays in clinical practice is that it can be used to obtain prognostic information in patients with increasing thyroglobulin (Tg) levels and negative 131 I whole-body scan post-thyroidectomy and radioiodine (RAI) ablation. FDG-PET/CT may also have a potential role in the initial staging and follow-up of high-risk patients with aggressive histological subtypes, in the identification of patients who are at the highest risk of disease-specific mortality, in the management of patients with RAI-refractory disease, in clinical trials of novel targeted therapies in patients with advanced metastatic disease, and in the evaluation of thyroid nodules with indeterminate fineneedle aspiration for cytology. However, several controversies remain to be resolved, namely: the cutoff value of Tg in the selection of DTC patients for FDG-PET/CT, whether FDG-PET/CT scanning should be performed under thyrotropin stimulation or suppression, and the clinical significance of thyroid FDG-PET/CT incidentalomas. The aim of the present article is to provide an overview of the data about the molecular basis for, clinical indications of, and controversies related to the use of FDG-PET/CT in patients with DTC.
