[Value of thyroglobulin determination in the follow up treatment of patients with thyroid cancer].

Tg measurements were performed regularly in 96 thyroid carcinomas in order to evaluate metastases and local recurrencies. Elevated Tg level was detected in 11 patient. 7 of them were operated on because of local recurrencies and lymph node metastases. All patients that needed reoperation had elevated Tg level. During the follow up period no patient needed reoperation who had elevated Tg level or metastases detected by other diagnostic procedures. Summarising the results they found the Tg level measurements valuable in the follow up of patients with differentiated thyroid cancer. The Tg level measurements can supplement or sometimes replace 131J thyroid scanning.
