Objective: Radioactive iodine (RAI) is used to ablate residual thyroid tissue after total thyroidectomy. The aim of this study was to evaluate the response according to the12th-month results of thyroid cancer patients and to investigate the changes in response level during follow-up. Materials and Methods: The study included 97 patients, comprising 88 (90.7%) females and 9 (9.3%) males, with a mean age of 41.68±13.25 years. None of the patients had lymph node or distant metastasis and all received RAI therapy. Thyroid-stimulating hormone (TSH), thyroglobulin (TG), and anti-TG levels and neck USG were examined in the 12th-month. Response to therapy was evaluated as an excellent response, biochemical incomplete response, structural incomplete response, or indeterminate response. Results: In the 12th month, 80 patients (82.47%) had excellent response, 13 patients (13.40%) had an indeterminate response, 3 patients (3.09%) had structural incomplete response and 1 patient (1.03 %) had biochemical incomplete response. Of the 80 patients with excellent response, 15 had no follow-up after the 12th month. The remaining 65 patients were followed up for 31.11±9.58 months. The response changed to indeterminate in the 18th month in 1 (1.54%) patient and to structural incomplete response in the 35th month in 1 (1.54%) patient. The 13 patients with indeterminate responses were followed up for 20.61±6.28 months. Conclusion: The TG level at 12th months provides accurate data about the course of the disease especially in patients with excellent responses. Patients with excellent response in the 12th month may be followed up less often and those with the indeterminate or incomplete responses should be followed up more often.

<b><i>Introduction:</i></b> Struma ovarii (SO) is a rare ovarian teratoma characterized by the presence of thyroid tissue in more than 50% of the tumor. Malignant transformation is rare and the most common associated malignancy is papillary thyroid carcinoma (PTC). Pregnancy may represent a stimulus to differentiated thyroid cancer (DTC) growth in patients with known structural or biochemical evidence of disease, but data about malignant SO evolution during pregnancy are rare. We present the first reported case of a pregnant patient with malignant SO and biochemical evidence of disease. <b><i>Case Presentation:</i></b> A previously healthy 35-year-old female diagnosed with a suspicious left pelvic mass on routine ultrasound was submitted to laparoscopic oophorectomy which revealed a malignant SO with areas of PTC. A 15-mm thyroid nodule (Bethesda V in the fine-needle aspiration cytology) was detected by palpation and total thyroidectomy was performed. Histology revealed a 15 mm follicular variant of PTC (T1bNxMx). Subsequently, she received 100 mCi of radioactive iodine therapy (RAIT) with the whole-body scan showing only moderate neck uptake. Her suppressed thyroglobulin (Tg) before RAI was 1.1 ng/mL. She maintained biochemical evidence of disease, with serum Tg levels of 7.6 ng/mL. She got pregnant 14 months after RAIT, and during pregnancy, Tg increased to 21.5 ng/mL. After delivery, Tg decreased to 14 ng/mL but, 6 months later, rose again and reached 31.9 ng/mL on the last follow-up visit. TSH was always suppressed during follow-up. At the time of SO diagnosis, a chest computed tomography scan showed 4 bilateral lung micronodules in the upper lobes which were nonspecific, and 9 months after diagnosis, a pelvic MRI revealed a suspicious cystic nodule located on the oophorectomy bed. These lung and pelvic nodules remained stable during follow-up. Neck ultrasonography, abdominal MRI, and fluorodeoxyglucose-positron emission tomography showed no suspicious lesions. <b><i>Discussion/Conclusion:</i></b> As for DTC, pregnancy seems to represent a stimulus to malignant SO growth. This can be caused by the high levels of estrogen during pregnancy that may bind to receptors in malignant cells and/or by the high levels of hCG which is known to stimulate TSH receptors.

Utility Analysis

6606 Background: In thyroid cancer patients, follow-up is designed to detect recurrent disease and consists of neck- ultrasonography (US), thyroglobulin measurement (Tg) and radioiodine whole body scan (WBS). Recent guidelines have restricted the use of WBS to suspicious cases. To insure diagnostic accuracy, follow-up control requires TSH stimulation, either with thyroid hormone withdrawal (THW) or rhTSH, which have demonstrated similar diagnostic accuracy. THW induces significant morbidity associated with hypothyroidism, leading to a decrease in patient quality of life and ability to work, whereas rhTSH is an innovative costly drug that avoids such patient burden. A societal cost-utility analysis was conducted to compare 4 follow-up strategies, combining a method of stimulation (rhTSH or THW) and a testing protocol (US+Tg+WBS or US+Tg alone). Methods: A Markov model was built to describe the follow-up of thyroid cancer patients first treated by thyroidectomy and radioiodine ablation, over 5 years. Estimates for diagnostic accuracy values and recurrence rate were extracted from a French multicenter randomized trial. Costs were computed from the perspective of the society, including medical resources consumed (hospitalisation, rhTSH, tests, treatment of recurrence). The model also incorporated the benefits of rhTSH in terms of quality of life (utility scores derived from SF36) and the reduction in duration and overall cost of sick leave. Results: Among the 753 patients included, 13 patients presented recurrence. rhTSH stimulation resulted in a higher utility score (0.802 vs. 0.637) over the period of stimulation and a reduction of 1083 € of absenteeism costs in active patients. As compared to the THW+Tg+US+WBS strategy, the incremental cost-utility ratios (ICER) showed economic dominance for the rhTSH strategies with ratios of −16,876 and −19,297 €/QALY with and without WBS respectively. The ICER for the strategy THW+US+Tg reached 29,333 €/QALY, as compared to THW+Tg+US+WBS strategy. Conclusions: the recommended strategy combining Tg determination and US after rhTSH stimulation appears the most cost-effective in the follow-up of thyroid cancer patients, as it is the strategy the less costly and associated with improved patient quality of life. No significant financial relationships to disclose.
