Temporary ovarian failure in thyroid cancer patients after thyroid remnant ablation with radioactive iodine.

We studied ovarian function retrospectively in 66 women who had regular menstrual cycles before undergoing complete thyroidectomy for differentiated thyroid cancer and subsequent thyroid remnant ablation with 131I. Eighteen women developed temporary amenorrhea accompanied by increased serum gonadotropin concentrations during the first year after 131I therapy. No correlation was found between the radioactive iodine dose absorbed, thyroid uptake before treatment, oral contraceptive use, or thyroid autoimmunity. Only age was a determining factor, with the older women being the most affected. We conclude that radioiodine ablation therapy is followed by transient ovarian failure, especially in older women.

[Solid cold thyroid nodule. Current data].

Attitudes adopted when confronted with a solid cold thyroid nodule are analyzed in the light of recent developments in paraclinical data represented essentially by results of immunological, ultrasound and fine needle cytopuncture examinations. The use of these new surveillance technics frequently allows surgery to be deferred, while if on the contrary operation is decided then it usually now involves both thyroid lobes to avoid nodular recurrence and repeat surgery. Postoperative follow up surveillance is essential to ensure individual adaptation of attitude: therapeutic abstention, suppressive or possibly compensatory treatment.

[Serum thyroglobulin is elevated in patients with heterogeneous goiter during radioiodide scintigraphy, but normal in those with homogeneous goiter].

Serum thyroglobulin (Tg) levels were determined in 98 biologically euthyroid patients with a diffuse or nodular goiter, and compared to values observed in 33 control subjects. Based on the results of clinical examination and thyroid scanning with radioiodine, patients were divided into 3 groups: group 1 with homogeneous diffuse goiters, group 2 with heterogeneous diffuse goiters without palpable nodules, and group 3 with solitary hypofunctioning nodules. The control group had a mean Tg of 37 +/- 15 micrograms/l. Group 1 (n = 32) had a mean Tg of 46 +/- 28 micrograms/l; six (19%) had an elevated Tg level (level greater than 74 micrograms/l). Group 2 (n = 30) had a mean Tg of 133 +/- 134 micrograms/l; fourteen (47%) had an elevated Tg level. Group 3 (n = 36) had a mean Tg of 188 +/- 191 micrograms/l; twenty (56%) had an elevated Tg level. The comparison of Tg between patient groups, and between patients groups and the control group, showed a significantly higher value in the groups of hypofunctioning nodules and heterogeneous diffuse goiters. It is concluded that the elevated serum Tg level in patients with a diffuse or nodular simple goiter is commonly associated with heterogeneity of the thyroid scan.

Serum thyroglobulin levels in hypofunctioning nodules before and after surgery.

Serum thyroglobulin (Tg) level was determined in 34 biologically euthyroid patients having benign hypofunctioning nodule, before and after surgery. Based on the results of thyroid scanning with radioiodine, 2 groups of patients were considered. Group 1 (n = 18) had solitary hypofunctioning nodule with an otherwise normal thyroid gland and group 2 (n = 16) had hypofunctioning nodule inside an enlarged and/or heterogeneous thyroid. Results were compared to a group of 30 control subjects. Mean Tg level was significantly elevated in both groups 1 and 2 before surgery. No significant difference was found between group 1 and group 2. After surgical removal of the hypofunctioning nodule (follicular adenoma), mean Tg level was normalized in group 1 and decreased but still remained elevated in group 2. It is concluded that the observed elevated serum Tg level is due to the presence of hypofunctioning nodule and/or heterogeneous thyroid tissue. Thus, Tg determination may be useful in the follow-up of operated hypofunctioning nodules in order to detect abnormality in the remaining thyroid tissue.
