The investigation and management of thyroid nodules--a retrospective review of 183 cases.

Abstract

The management of the patient with a thyroid nodule remains a clinical challenge because of its risk of malignancy. This is a retrospective audit of 183 patients undergoing thyroidectomy for thyroid nodules at the Queen Elizabeth Hospital, Hong Kong, in 1994. The history, physical examination and investigations done were charted and analysed against the final histopathology of the specimens. Age, sex, symptom duration and nodularity were not associated with malignancy statistically, whereas a nodule hard in consistency was shown to be associated with malignancy (P < 0.05). The sensitivity and specificity of ultrasonography, radionuclide scan and fine-needle aspiration cytology (FNAC) were 71% and 57%, 50% and 43%, and 93% and 60%, respectively. Hence, history and physical examination are unreliable for detecting malignant thyroid nodules and FNAC is mandatory. FNAC is superior to ultrasonography or radionuclide scan for evaluating thyroid nodules and should be used as the initial investigation.
