  • Title: Thyroid nodules: does the suspicion for malignancy really justify the increased thyroidectomy rates?
    Author: Sakorafas GH, Peros G, Farley DR.
    Journal: Surg Oncol; 2006 Jul; 15(1):43-55. PubMed ID: 16950080.
    Abstract:
    Thyroid nodules are frequently diagnosed today, mainly due to the wide use of neck ultrasonography (US). The majority of these are benign; suspicion for malignancy is an indication for surgery, while benign thyroid nodules may be managed conservatively. There is evidence that a large percentage of patients with thyroid nodules (many diagnosed incidentally) are over-treated. Careful and accurate identification of patients with thyroid nodules highly suspicious for underlying malignancy would allow a more reasonable therapeutic approach and would result in a reduction of the number of unnecessary thyroidectomies. Fine-needle aspiration cytology (FNAC), in conjunction with high-resolution thyroid US, are currently the most accurate and cost-effective diagnostic approach for the evaluation of patients with nodular thyroid disease. Radionuclide thyroid scanning should be used selectively. By increasing the use of FNAC, it is expected that the number of unnecessary thyroidectomies will be further diminished, thereby avoiding over-treatment, without exposing the patients to the risk of under-treatment for a highly curable cancer. However, accurate preoperative diagnosis of thyroid cancer within a thyroid nodule is not always possible and, although the problem of unnecessary surgery can further be diminished, it cannot be completely eliminated.
