Summary Aim: Tumor scintigraphy with 201-TICI is an established diagnostic method in the follow-up of differentiated thyroid cancer. We investigated the relationship between thyroglobulin (Tg) level and tumor detectability. Subject and methods: We analyzed the scans of 122 patients (66 patients with proven tumor). The patient population was divided into groups with Tg above (N = 33) and below (N = 33) 5 ng/ml under TSH suppression or above (N = 33) and below (N = 33) 50 ng/ml under TSH stimulation. Tumor detectability was compared by ROC-analysis (True-Positive-Fraction test, specificity 90%). Results: There was no significant difference (sensitivity 75% versus 64%; p = 0.55) for patients above and below 5 ng/ml under TSH suppression and a just significant difference (sensitivity 80% versus 58%; p = 0.04) for patients above and below 50 ng/ml under TSH stimulation. In 18 patients from our sample with tumor, Tg under TSH suppression was negative, but 201-TICI-scan was able to detect tumor in 12 patients. Conclusion: Our results demonstrate only a moderate dependence of tumor detectability on Tg level, probably without significant clinical relevance. Even in patients with slight Tg elevation 201-TICI scintigraphy is justified.

Background: Low risk thyroid cancer can be treated with lobectomy or total thyroidectomy. Studies have shown that the risk of recurrence does not differ between the two surgeries, although there are higher rates of complications with total thyroidectomy. Our study aimed to find if there were differences in quality of life and thyroid function in the two treatments. Methods: Low risk DTC survivors answered three QoL questionnaires (EQ5D3L, SF36, and EORTC QLQ C30) and had their thyroid function evaluated. Results: Twenty-six lobectomy patients and 101 total thyroidectomy were included. Hypoparathyroidism occurred more in the total thyroidectomy, and TSH was more likely to be on target (0.5-2.0) in lobectomy. There was no difference between groups regarding QoL, but there was a significant difference regarding thyroid function. In SF36 form, TSH off target led to more physical limitations, pain, less vitality, and worse social aspects. Abnormal total T3 level was associated with pain, less vitality, and worse mental health. In the EORTC QLQ C30, off target TSH led to worse role functioning, fatigue, and nausea. EQ5D form showed that worse utility index was found when TT3 was not in normal range. Conclusion: This study showed there was a difference among thyroid function, specially TSH depending on type of surgery. When uncontrolled, TSH was associated with worse aspects of the quality of life. Therefore, lobectomy patients have a better thyroid function control and less surgical complications which might have an impact in some aspects of the quality of life when compared to total thyroidectomy.

Tsh Levels

Less-intense TSH suppression strategies can be used for differentiated thyroid cancer (DTC) patients with a low recurrence risk, but their metabolic outcomes are not well known. We aimed to evaluate changes in the serum cholesterol levels and the risk of hypercholesterolemia according to postoperative TSH levels in 1092 female DTC patients receiving levothyroxine after total thyroidectomy. The preoperative-to-follow-up change in total cholesterol (TC) levels in the TSH level <0.03, 0.03–0.3, 0.3–2, and 2–5 mIU/L groups was −3.69 mg/dL (p = 0.006), +0.13 mg/dL (p = 0.926), +12.46 mg/dL (p < 0.001), and +16.46 mg/dL (p < 0.001), respectively. When compared with TSH levels of 0.03–0.3 mIU/L, those of 0.3–2 mIU/L were found to be associated with hypercholesterolemia (adjusted odds ratio (AOR) = 1.86 and 5.08 for TC 200–240 and ≥240 vs. <200 mg/dL) and hyper-low-density lipoprotein (LDL)-cholesterolemia (AOR = 2.76 for LDL-cholesterol ≥160 vs. <130 mg/dL). Additionally, TSH levels of 2–5 mIU/dL were associated with hypercholesterolemia (AOR = 2.85 and 6.95 for TC 200–240 and ≥240 vs. <200 mg/dL) and hyper-LDL-cholesterolemia (AOR = 2.08 and 4.17 for LDL-cholesterol 130–159 and ≥160 mg/dL vs. <130 mg/dL). In patients with normal TSH level maintenance following thyroidectomy, TC levels markedly increased, resulting in an increased hypercholesterolemia prevalence. Metabolic derangement risk due to insufficient levothyroxine replacement should be considered in the adoption of less-intense TSH suppression strategies, postoperatively, in DTC patients.
