title: Preoperative physical assessment of thyroid glands in previously irradiated patients.
abstract: The Evanston Hospital maintains an Irradiated Thyroid Evaluation Clinic that has evaluated 695 patients since 1975. One hundred fourteen patients were retrospectively analyzed, and an attempt was made to correlate the preoperative physical examination with the pathologic specimen after thyroidectomy. There was no statistically significant difference between the incidence of carcinoma in glands containing a single nodule (23 per cent) and in multinodular glands. Postirradiation thyroiditis complicated the physical description of glands preoperatively. The categorization of physical findings served only to identify persistent thyroid abnormalities, which must be explored surgically. The overall incidence of carcinoma in the 114 available cases was 34 per cent, with nodal metastases in 18 per cent of the patients with carcinoma.
