Progress in the preoperative diagnosis of thyroid nodules: managing uncertainties and the ultimate role for molecular investigation.
The preoperative evaluation of thyroid nodules currently relies on a clinical assessment of risk factors and an algorithm based on imprecise tests. With serum TSH, thyroid ultrasound and fine-needle aspiration (FNA) with or without ultrasound guide, accounting for the routine initial evaluation, indeterminate aspirates remain the major obstacle for confidently advising patients whether to have surgery or not. Recent clinical guidelines have attempted to settle various controversies but many inherent errors of clinical testing result in delayed diagnosis and unnecessary surgery. A better solution may ultimately involve the use of molecular markers of thyroid carcinogenesis but further research is still needed regarding the basic biology of thyroid cancer.
