A Rare Case of Thyrotropin-Secreting Pituitary Adenoma Coexisting with Papillary Thyroid Carcinoma Presenting with Visual Disturbance without Hyperthyroidism. World Neurosurg 2018; 119:394-399. [PMID: 30096503 DOI: 10.1016/j.wneu.2018.07.274] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Revised: 07/29/2018] [Accepted: 07/30/2018] [Indexed: 01/25/2023]
Abstract
BACKGROUND Thyroid-stimulating hormone-secreting pituitary adenomas (TSHomas) are uncommon, and majority of the patients present with symptoms of hyperthyroidism. Herein, we report the first case of TSHoma with differentiated thyroid carcinoma (DTC) that presented with visual disturbance without any clinical feature of hyperthyroidism. CASE DESCRIPTION A 57-year-old man presented with left temporal hemianopsia of his left eye without any sign of hyperthyroidism. A mass lesion in the sellar and suprasellar region compressing the optic nerves was identified via magnetic resonance imaging. Free thyroxine and free triiodothyronine levels were slightly elevated, whereas the serum level of thyroid-stimulating hormone remained within normal range. Further endocrinologic examination led to the preoperative diagnosis of TSHoma. Ultrasonography and 111In-octreotide scan showed a mass lesion in left lobe of the thyroid gland, and subsequent thyroid aspiration biopsy confirmed the diagnosis of papillary thyroid carcinoma. After administration of short-acting octreotide to prevent thyrotoxic crisis in the perioperative period, the tumor was removed via endoscopic transnasal-transsphenoidal surgery, and the pathologic diagnosis of TSHoma was made. His visual acuity improved, and free triiodothyronine and free thyroxine levels normalized. He underwent thyroidectomy 3 months later after endoscopic transnasal-transsphenoidal surgery. CONCLUSIONS Herein, we report the first case of TSHoma with DTC that presented with visual disturbance without any clinical feature of hyperthyroidism and reviewed the 13 reported cases of TSHoma coexisting with DTC. The optimal treatment strategy in patients with TSHoma and coexistent DTC has not been established, and individualized therapeutic strategies are needed.

Abstract
BACKGROUND Thyroid carcinoma is the most common endocrine malignancy and has an increasing incidence. High-frequency ultrasound (HFUS) has a spatial resolution of 30 μm, which is a property that has been exploited for thyroid visualization and analysis in mice. The aim of this study was to generate a novel orthotopic mouse model of human follicular thyroid carcinoma (FTC) using an HFUS-guided injection system. METHODS Twenty Balb/C nude mice were injected in the right lobe of the thyroid with 2 × 10(6) FTC-133 cells using the microinjection HFUS-guided system, and 20 mice, used as a control, underwent surgical orthotopic implantation of 2 × 10(6) FTC-133 cells in the right lobe of the thyroid. All mice underwent HFUS imaging two weeks after cell injection; HFUS examinations and tumor volume (TV) measurements were repeated weekly. Micro-computed tomography was performed at different time points to determine whether lung metastasis had occurred. TVs were compared between the two models (surgical vs. HFUS-guided) using the Mann-Whitney U-test, and the Mantel-Cox log-rank test was applied to evaluate the death hazard. Hematoxylin and eosin analysis of formalin-fixed, paraffin-embedded mouse tissue was performed to validate the in vivo imaging results. RESULTS Of the HFUS-guided injected mice, 9/18 survived up to 40 days after the injection of tumor cells. Mice injected surgically had 100% mortality at day 29. Of 38 mice, 29 (14/18 HFUS, 15/20 surgical) showed metastasis in the salivary glands and lymph nodes, and 13 (10/18 HFUS, 3/20 surgical) also showed metastasis in the lungs, which was confirmed by histological analysis. In the surgical group, there was an evident, frequent (12/20 mice) involvement of the contralateral lobe of the thyroid, whereas this feature was only detected in 1/18 mice in the HFUS group. Statistical analysis showed the same pattern of growth in the two groups, and a significant hazard in the mice in the surgical group (p = 0.03). CONCLUSIONS This study demonstrated the technical feasibility of an HFUS-guided orthotopic mouse model of FTC. The HFUS-guided orthotopic model is easily reproducible and allows prolonged monitoring of the disease because the animals showed an increased survival rate.

Abstract
BACKGROUND Patients with a thyrotropin-secreting pituitary adenoma (TSHoma) are exposed to unregulated and inappropriately high levels of thyrotropin (TSH). Given the rarity of this condition, it is not known whether this chronic TSH stimulation of the thyroid gland might represent a risk factor for the development of differentiated thyroid cancer (DTC). We analyzed the incidence of DTC in a large cohort of patients with TSHomas. METHODS The study population consisted of all consecutive patients who underwent neurosurgery for a TSHoma between 1990 and 2013. Criteria for the diagnosis of TSHoma in patients without previous thyroid ablative procedures included elevated free thyroid hormones and normal/high serum TSH concentrations, presence of a lesion at magnetic resonance imaging (MRI), and abnormal response of TSH to at least one dynamic test. Patients who had received thyroid ablative procedures were required to have a pituitary lesion on MRI and TSH levels not suppressed while on levothyroxine therapy at doses causing elevation of free thyroid hormone levels. RESULTS Sixty-two patients (32 females, 30 males) underwent surgery for a TSHoma at our center. Among them, 3 patients had a coexistent diagnosis of DTC with an estimated incidence of 4.8%. In 2 patients, DTC was diagnosed during the evaluation for suspected TSH-dependent hyperthyroidism, whereas in the third patient, diagnosis of DTC preceded the detection of the pituitary tumor. CONCLUSIONS The elevated incidence of DTC in patients with TSHoma suggests a possible role of TSH hypersecretion in the development of thyroid tumors. A formal high-resolution ultrasound of the thyroid is recommended in patients diagnosed with a TSHoma, especially if a long history of the pituitary tumor is suspected. Moreover, suspicion about the presence of TSHoma should be raised by the lack of suppression of TSH levels despite adequate doses of levothyroxine after thyroidectomy for DTC.

Abstract
BACKGROUND Recently, it has been reported that the risk of thyroid malignancy increases with increasing concentrations of serum thyroid-stimulating hormone (TSH). The purpose of this study was to determine whether or not serum TSH can be a predictor for thyroid malignancy when considering the relevant ultrasound features and clinical risk factors. METHODS This retrospective study included 1200 euthyroid patients with 1269 thyroid nodules who underwent ultrasound-guided fine-needle aspiration (FNA) biopsy between January and June 2009. Serum TSH, ultrasound feature, and clinical parameters were compared according to final diagnosis. Subgroup analyses were performed according to nodule size. RESULTS Serum TSH did not show a positive association with malignancy for all nodules and the micronodule subgroup in multivariate analysis, although they showed significant association with thyroid malignancy for the macronodule subgroup. For all nodules and the 2 subgroups, suspicious ultrasound features and younger age were significantly associated with malignancy in univariate and multivariate analyses. CONCLUSION Our study suggests that TSH alone is not as useful as ultrasound features in deciding whether or not to perform FNA in patients with micronodules.

Abstract
OBJECTIVE To investigate the correlation between serum thyroid-stimulating hormone (TSH) concentration and nodule nature in pediatric patients with thyroid nodules, with the aim of identifying a marker able to differentiate benign and malignant nodules. STUDY DESIGN This was a retrospective analysis of serum TSH concentrations in a multicentric case series of 125 pediatric patients with benign and malignant thyroid nodules. RESULTS Of the 125 patients, 99 had benign thyroid nodules and 26 had differentiated thyroid cancer (24 papillary and 2 follicular). Final diagnosis was based on surgery in 57 cases and on a benign cytology plus clinical follow-up in 68 cases. Serum TSH concentration was significantly higher in patients with thyroid cancer compared with those with benign nodules (3.23 ± 1.59 mU/L vs 1.64 ± 0.99 mU/L; P < .001). Binary logistic regression analysis revealed that serum TSH was the sole predictor of malignancy (P < .001). Dividing the patient cohort into 5 groups based on serum TSH quintiles (TSH cutoffs 0.40, 1.00, 1.50, 1.80, and 2.80 mU/L), we observed that cancer prevalence increased in parallel with serum TSH (P < .001), with respective rates of 0%, 4%, 16%, 32%, and 52% in the 5 quintile groups. CONCLUSION Because cases with malignant nodules are most likely seen in the upper normal serum TSH range (ie, >2.8 mU/L), serum TSH concentration can serve as a predictor of thyroid cancer in pediatric patients with thyroid nodules and can inform the decision of when to submit patients to further investigation by cytology.

Abstract
Curcumin, the active constituent of dietary spice turmeric, possesses a strong potential for cancer prevention and treatment. However, there is no study to address the effects of curcumin on invasion and metastasis of thyroid cancers. Thyroid cancer is the most common malignancy of endocrine organs, and its incidence rates have steadily increased over recent decades. Although most indolent tumours can be effectively managed, metastatic tumours at distant secondary sites behave aggressively and currently there is no effective form of treatment. Here, for the first time it has been reported that curcumin inhibit multiple metastasis steps of K1 papillary thyroid cancer cells. Curcumin dose-dependently suppressed viability of K1 cells as well as its cell attachment, spreading, migration and invasion abilities. Moreover, curcumin could also down-regulate the expression and activity of matrix metalloproteinase-9 (MMP-9). The findings showed that curcumin might be an effective tumouristatic agent for the treatment of aggressive papillary thyroid carcinomas.

Abstract
Up to now, there are no curative therapies available for the subset of metastasized undifferentiated/anaplastic thyroid carcinomas. This review describes the possible use of immunocompetent cells which may help to restore the antitumor immune recognition for treating an existing tumor or preventing its recurrence. The most prominent experimental strategy is the use of dendritic cells (DCs) which are highly potent in presenting tumor antigens. Activated DCs subsequently migrate to draining lymph nodes where they present antigens to naïve lymphocytes and induce cytotoxic T cells (CTL). Alternatively to DC therapy, adoptive cell transfer may be performed by either using natural killer cells or ex vivo maturated CTLs. Within this review article we will focus on recent advances in the understanding of anti-tumor immune responses, for example, in thyroid carcinomas including the advances which have been made for the identification of potential tumor antigens in thyroid malignancies.

Abstract
The thyroid gland has long since been known for its self-renewal ability, mainly in cases of hyperplastic disease such as goitre. Recently the amazing improvement in knowledge about stem cells has explained this potentiality. Some stem cell features and their clinical usefulness are summarized here, reviewing data from the literature: (1) the proven presence of adult stem cells in thyroid tissue, either normal, goitrous or neoplastic, bring with it important implications regarding tissue regeneration and oncogenesis; (2) modifying culture conditions and micro-environment stem cells have led to mature tissue with specialized functions. This has considerably changed the attitude of regenerative medicine and cancer research; (3) finally, identification of stem cells and stem cell markers in thyroid cancer, gives hope for the development of new therapeutic approaches in recurrent or treatment-resistant thyroid cancer.
