Tumor markers in the early diagnosis of thyroid neoplasms

Radioimmunological techniques were used to assay tumour markers in order to identify neoplasms in patients with thyroid nodules at the earliest possible stage. In the 7 patients with differentiated thyroid tumours, the marker findings were within normal limits. On the basis of these results it is concluded that at the present time these markers are of no value for the early diagnosis of thyroid tumours.
