Fine needle aspiration cytology in the management of solitary thyroid nodules--a comparison with other diagnostic modalities in cost-effectiveness.
This paper assesses the cost effectiveness of fine needle aspiration cytology (FNAC) as a selection criteria for surgery in solitary thyroid nodules compared to scintigraphy and ultrasonography. 98 patients who had FNAC and histological confirmation, scintigraphy and/or ultrasonography were studied. The use of combined diagnostic discriminants of positive FNAC, clinical suspicion and age above 50 years detected all malignancies and would have resulted in fewer patients being subjected to surgery--51% (FNAC) vs 90% (Scans, U/S). This resulted in cost savings of $800 per patient seen. We conclude therefore that FNAC should be the diagnostic modality of choice and that the routine use of scintigraphy and ultrasonography is not justifiable.
