The outcome of patients with thyroid carcinoma and Graves' disease.
A total 847 consecutive patients with Graves' disease who underwent thyroidectomy between 1965 and 1990 were found to have a 4.3% incidence of coincident carcinoma of the thyroid. In 68.2% of these cases the tumors were less than 1 cm in diameter and were detected in only 7 patients (19.4%) prior to surgery. Dissection of the regional lymph nodes was necessary in only 11 patients. A review of the patients in 1990 revealed no carcinoma-related deaths with metastases occurring most commonly in the patients with larger tumors and in those whose cancer had been detected prior to thyroidectomy. Although the detection of potential tumors occurring with Graves' disease using preoperative echogram may be of interest, our results suggest that occult microcarcinoma occurring coincidentally with Graves' disease is not clinically significant as it did not cause any recurrence in this study. Moreover, there was no evidence to suggest that Graves' disease was associated with the increased or rapid growth of these tumors.
