During a period of 20 years (1965-1985), 206 consecutive patients were operated on for radiation-associated nodular thyroids. The ages ranged between 8 and 76 years (mean 38.7). there were 136 women and 70 men. The average duration between radiation exposure and operation was 27 years. The operations performed were total thyroidectomy (192) or, in patients who had undergone a previous lobectomy in another institution, another lobectomy (14). In addition, 25 patients required a neck dissection for nodal metastases and 27 underwent simultaneous subtotal parathyroidectomy for coexistent hyperparathyroidism. The pathologic findings were: 87 (42.2%) carcinoma (73 papillary, 13 follicular, 1 undifferentiated); 92 (44.7%) follicular adenomas; and 27 (13.1%) thyroiditis. To date, with an average follow-up of 6 years (0.5-31 years), only two patients have expired from recurrent disease. A third died of unrelated cause. A comparison of the first 100 patients (12 years) with the last 106 patients (8 years) demonstrated that the incidence of carcinoma has dropped from 48 to 37%, the incidence of lymph node metastases has decreased from 35 to 26%, and the incidence of bilaterality has fallen from 75 to 54%. On the basis of this series, it was concluded that total thyroidectomy is still indicated for radiation-associated nodular thyroids. However, if the trend of decreasing incidence, bilaterality, and metastatic disease persists, this approach may have to be reevaluated in the near future.
