    Differentiated thyroid carcinoma (DTC) is the most common endocrine malignancy. Surgical removal with radioactive iodine therapy is recommended for recurrent thyroid carcinoma, and the postsurgical thyroid removal is critical. This study evaluated the clinical values of radiofrequency ablation (RFA) in the postsurgical thyroid removal for DTC. 35 DTC patients who had been treated by subtotal thyroidectomy received RFA for postsurgical thyroid removal. Before and two weeks after RFA, the thyroid was examined by ultrasonography and 99mTcO4 - thyroid imaging, and the serum levels of free triiodothyronine (FT3), free thyroxin (FT4), thyroid stimulating hormone (TSH) and thyroglobulin (Tg) were detected. The efficacy and complications of RFA were evaluated. Results showed that, the postsurgical thyroid removal by RFA was successfully performed in 35 patients, with no significant complication. After RFA, the average largest diameter and volume were significantly decreased in 35 patients (P > 0.05), and no obvious contrast media was observed in ablation area in the majority of patients. After RFA, the serum FT3, FT4 and Tg levels were markedly decreased (P < 0.05), and TSH level was significantly increased (P < 0.05). After RFA, radioiodine concentration in the ablation area was significantly reduced in the majority of patients. The reduction rate of thyroid update was 0.69±0.20%. DTC staging and interval between surgery and RFA had negative correlation (Pearson coefficient = -0.543; P = 0.001), with no obvious correlation among others influential factors. RFA is an effective and safe method for postsurgical thyroid removal of DTC. PMID:27186311

    An analysis of differentiated thyroid carcinomas in children and adolescents revealed that the incidence was 3.05% of total number of patients with differentiated thyroid cancers in all age groups. There was a female preponderance. The incidence of papillary, follicular and papillary with follicular elements was equal. There were no papillary carcinomas observed in children younger than 10 years. The predominant mode of presentation was a solitary nodule of thyroid and some of them had associated cervical adenopathy. A considerable number presented with only cervical adenopathy. The incidence of nodal metastases was 50% at time of presentation and lung involvement was present in 15% of children at the time of diagnosis. Radioiodine treatment was given in 70% of children. Ablation was achieved in 86% of patients given two doses of radioiodine (200 millicuries). The more resistant cases were those with lung and nodal metastases. There was complete ablation in 100% with only residual thyroid tissue, 83% in those with associated nodal metastases, and 57% in those with lung involvement. Average duration of follow-up was 10.3 years (range, 2 to 19 years). Recurrence rate or relapse was observed in 8.5% and was in the regional nodes. There was no recorded mortality due to the disease.

  4. External Beam Radiation in Differentiated Thyroid Carcinoma.

    The treatment of differentiated thyroid carcinoma (DTC) is surgery followed in some cases by adjuvant treatment, mostly with radioactive iodine (RAI). External beam radiotherapy (EBRT) is less common and not a well-established treatment modality in DTC. The risk of recurrence depends on three major prognostic factors: extra-thyroid extension, patient's age, and tumor with reduced iodine uptake. Increased risk for recurrence is a major factor in the decision whether to treat the patient with EBRT. Data about the use of EBRT in DTC are limited to small retrospective studies. Most series have demonstrated an increase in loco-regional control. The risk/benefit from giving EBRT requires careful patient selection. Different scoring systems have been proposed by different investigators and centers. The authors encourage clinicians treating DTC to become familiarized with those scoring systems and to use them in the management of different cases. The irradiated volume should include areas of risk for microscopic disease. Determining those areas in each case can be difficult and requires detailed knowledge of the surgery and pathological results, and also understanding of the disease-spreading pattern. Treatment with EBRT in DTC can be beneficial, and data support the use of EBRT in high-risk patients. Randomized controlled trials are needed for better confirmation of the role of EBRT.

    The aim of follow-up of differentiated thyroid carcinoma (CTD) is the assessment of remission, and, in further steps, the early recognition of patients who develop a recurrence. Tools for the follow-up of CTD include the assessment of thyroglobulin and imaging procedures. Thyroglobulin (Tg) is a strong marker of persistent or recurrent disease, but it must be known that Tg antibodies may give falsely low Tg concentration. TSH stimulation, mainly by the mean of recombinant human TSH, improves the sensitivity of Tg determination. New highly sensitive assays may preclude the need for TSH stimulation, at least in some situations. In the last decades, (131)iodine whole body scan gave place to neck ultrasonography (US) as the most performing imaging procedure in the follow-up of CTD. Criteria to identify cervical lymph node suspect of metastasis have been described, and standardized procedures proposed. Finally, the proof of tumoral invasion is brought by cytological analysis of fine needle biopsies of suspicious lymph nodes. (18)FDG PET is a valuable tool for diagnosis and prognosis in metastatic patients, especially with negative (131)I WBS. Initial response to therapy, assessed by Tg determination and neck US, allows re-stratification of the risk of relapse. According to this "reassessed risk", adapted rhythms and modalities of follow-up have been recently proposed. PMID:26826480

  6. Genomic Landscape of poorly Differentiated and Anaplastic Thyroid Carcinoma.

    2016-09-01

    Poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid carcinoma (ATC) are aggressive thyroid tumors associated with a high mortality rate of 38-57 % and almost 100 % respectively. Several recent studies utilizing next generation sequencing techniques have shed lights on the molecular pathogenesis of these tumors, providing evidence to support a stepwise tumoral progression from well-differentiated to poorly differentiated, and finally to anaplastic thyroid carcinomas. While BRAF (V600E) and RAS mutations remain the main drivers in aggressive thyroid carcinoma, PDTC and ATC gains additional mutations, e.g., TERT promoter mutation, TP53 mutation, as well as frequent alterations in PIK3CA-PTEN-AKT-mTOR pathway, SWI-SNF complex, histomethyltransferases, and mismatch repair genes. RAS-mutated PDTCs are commonly associated with a histologic phenotype defined by Turin proposal, high frequency of distant metastasis, high thyroid differentiation score, and a RAS-like gene expression profile, whereas BRAF-mutated PDTCs are usually defined solely by the Memorial Sloan Kettering Cancer Center (MSKCC) criteria with a propensity for nodal metastasis and are less differentiated with a BRAF-like expression signature. Such demarcation is largely lost in ATC which is characterized by genomic complexity, heavy mutation burden, and profound undifferentiation. Additionally, several molecular events, e.g., EIF1AX mutation, mutation burden, and chromosome 1q gain in PDTCs, as well as EIF1AX mutation, chromosome 13q loss, and 20q gains in ATCs, may serve as adverse prognostic markers predicting poor clinical outcome.

    Background: The clinical behavior and management of poorly differentiated thyroid carcinoma (PDTC) are very different from papillary thyroid carcinoma (PTC). By comparing the clinical and ultrasonographic features between the two tumors, we proposed to provide more possibilities for recognizing PDTC before treatment. Methods: The data of 13 PDTCs and 39 age- and gender-matched PTCs in Peking Union Medical College Hospital between December 2003 and September 2013 were retrospectively reviewed. The clinical and ultrasonic features between the two groups were compared. Results: The frequencies of family history of carcinoma, complication with other thyroid lesions, lymph node metastases, recurrent laryngeal nerve injuries, and distant metastases were higher in PDTCs (30.8%, 61.6%, 69.2%, 23.1%, and 46.2%, respectively) than those in PTCs (2.6%, 23.1%, 25.6%, 2.6%, and 2.6%, respectively) (P < 0.05). The mortality rate of PDTCs was greatly higher than PTCs (P < 0.01). Conventional ultrasound showed that the size of PDTCs was larger than that of PTCs (3.1 ± 1.9 cm vs. 1.7 ± 1.0 cm). Clear margins and rich and/or irregular blood flow were found in 92.3% of PDTCs, which differed substantially from PTCs (51.7% and 53.8%, respectively) (P < 0.05). Conclusions: PDTC is more aggressive and its mortality rate is higher than PTCs. Accordingly, more attention should be given to suspicious thyroid cancer nodules that show large size, regular shape, and rich blood flow signals on ultrasound to exclude the possibility of PDTCs.

    Differentiated thyroid carcinoma (DTC) comprises over 90% of thyroid tumors and includes papillary and follicular carcinomas. Patients with DTC have an excellent prognosis, with a 10-year survival rate of over 90%. However, the risk of recurrent tumor ranges between 5% and 30% within 10 years of the initial diagnosis. Cervical lymph node disease accounts for the majority of recurrences and in most cases is detected during follow-up by ultrasound or elevated levels of serum thyroglobulin. Recurrent disease is accompanied by increased morbidity. The mainstay of treatment of nodal recurrence is surgical management. We provide an overview of the literature addressing surgical management of recurrent or persistent lymph node disease in patients with DTC. PMID:26886954

    Current methods for diagnosing thyroid carcinoma are time consuming or expensive. Thus, alternative approaches are required. In the present study, microRNAs (miRNAs) with higher sensitivity and specificity were screened while distinguishing between differentiated thyroid carcinoma (DTC) and subtype papillary thyroid carcinoma (PTC). A total of 120 cases suspected of having thyroid carcinoma were selected and examined using clinical color Doppler ultrasound, and computed tomography scan at the same time. The tissue specimens were obtained with fine needle aspiration, multiphase biopsy and surgical resection. The expression of miR146b, miR221 and miR222 was detected uisng the RT-quantitative polymerase chain reaction method. The receiver operating characteristic curve was used to obtain the cut-off value. Pathological examination identified 8 cases of normal thyroid tissue; 9 cases of hyperplastic nodules; 12 cases of thyroid adenoma; and 91 cases of thyroid carcinoma, of which 59 cases were DTC, 15 cases were follicular carcinoma and 17 cases were undifferentiated carcinoma. In the thyroid carcinoma, the expression levels of miR146b, miR221 and miR222 were significantly higher than those of other tissues (P<0.05). The expression levels of these miRNAs in the differentiated type were also significantly higher than those in the undifferentiated type (P<0.05). A comparison of the differentiated subunit identified no statistically significant difference (P>0.05). Following diagnosis of DTC, the area under curve (AUC) of miR146b, miR221 and miR222 was 0.832, 0.806 and 0.745, respectively; the cut-off values were 1.346, 1.213 and 1.425, respectively; susceptibility was 72.8, 71.5 and 68.7%, respectively; and specificity was 62.3, 60.9 and 59.3%, respectively. The AUC of the combined miR-146b and −221 following diagnosis of PTC was 0.695; the cut-off values were 1.506 and 1.462, respectively; susceptibility was 78.9%; and specificity was 68.5%.

    Carcinoma showing thymus-like differentiation (CASTLE) is a rare intrathyroidal neoplasm, probably arising from ectopic thymus or branchial pouch remnants. The tumor was first reported by Miyauchi et al. [1].The clinical and pathological features of this tumor were classified by Chan et al. [2] into 4 groups: ectopic hamartomatous thymoma, ectopic cervical thymoma, spindle ephithelial tumor with thymic-like differentiation (SETTLE), and carcinoma showing thymus-like differentiation (CASTLE). Recently, CASTLE has been designated as an independent clinicopathologic entity of thyroid tumors in the most recent edition of the World Health Organization classification of tumors of endocrine organs[3].To our knowledge, less than 100 cases of CASTLE have been reported in the literature, 45 cases of which (including one of the authors' patient) have been identified in China. We report a new case of this entity and suggest recommendations for diagnosis. PMID:23920320

    Differentiated thyroid carcinoma was studied with regard to mode of presentation, initial findings, treatment and survival. The classic signs, symptoms, physical and scan findings were found to be present in approximately 70% of the patients. Prognosis was found to be dependent on age of presentation more than any other factor. Patients with prior exposure to radiation were found to have more extensive disease and require more extensive surgery but ultimately had the same prognosis for 15-year cure. Treatment for distant metastatic disease by surgery, radioactive iodine and external radiation all resulted in long-term survival in certain cases.

    Background: Poorly differentiated thyroid carcinomas (PDTCs) lie, both morphologically and behaviorally, between well-differentiated and undifferentiated carcinomas. Metastasis of poorly differentiated thyroid carcinoma to the intranasal cavity has not been reported previously in the literature. Case Report: A 48-year-old male patient presented with massive epistaxis and nasal obstruction. On nasal examination, a bleeding, vascular mass was seen filling the left nasal cavity. The histopathological report of the nasal mass was well-differentiated thyroid carcinoma metastasis. Whole body scintigraphy, ultrasonography and positron emission tomography were done to rule out other possible metastases in the body and determine the origin of the tumor, which was identified as the left lobe of the thyroid gland, and there were multiple metastases involving the lung, sacroiliac area, and left humerus. Histopathological examination of a thyroidectomy specimen revealed PDTC consisting of insular, follicular, and papillary components. Postoperatively, the patient received radioactive iodine ablation therapy (iodine-131) and a course of external beam radiation therapy to the sacroiliac area and other metastatic regions. No recurrences were observed in a follow-up period of 5 years after surgery. Conclusion: The metastasis of differentiated thyroid carcinoma as a component of PDTC to the intranasal cavity has not been reported before. It is interesting that the well-differentiated component of the tumor was metastasized in our patient. Due to the aggressiveness of PDTC and the poor survival rates in patients who undergo surgery alone, a multidisciplinary treatment approach is required. PMID:26185723

    We evaluated the correlation between serum thyroid-stimulating hormone (TSH) levels and tumor size and other invasiveness parameters of tumor in patients with differentiated thyroid carcinoma (DTC). Several clinical studies have reported that TSH may also have a role as a regulator of the development and function of the thyroid gland. It is currently not clear whether TSH is involved in the existence of thyroid cancer or progression of thyroid cancer or both. Patients with DTC who underwent thyroid surgery between 2003 and 2008 were included this study. Preoperative serum T3, T4, and TSH levels were compared with the size and invasiveness of cancer, retrospectively. DTC was observed in 110 patients over the 5-year period. Seventy-seven (70 %) of them were euthyroid and classified as the "normal-TSH group" (NTG), and 33 (30 %) have an overt or subclinical hyperthyroidism, classified as the "low-TSH group" (LTG). The mean tumor diameter in the LTG was found to be 8.91 ± 8.03 mm; however, it was found to be 18.19 ± 16.24 mm in the NTG. There were significantly differences among the groups related to the diameter of tumor (p = 0.001). Microcarcinoma was determined in 36 patients (46.8 %) in the NTG and 23 patients (69.7 %) in the LTG (p = 0.027). Although there were no significant differences, tumor capsule invasion (33.8 vs. 18.2 %, p = 0.099) and lymphovascular invasion (16.9 vs. 6.1 %, p = 0.130) rates were higher in the NTG. These findings suggest that TSH has effects on growing and proliferation of not only normal thyroid cells but also cancer cells in DTC. This study revealed that serum TSH level can be explored as an important factor that affects the size and invasiveness of tumor in DTC. PMID:27011492

    Purpose: The aim of this study has been to perform a dosimetric study in the treatments of differentiated thyroid cancer (DTC) performed in our center in order to find a dose-effect correlation. Methods: Thirty patients treated for DTC with 3700 MBq of {sup 131}I have been included in this study. For reasons of radiological protection all of them spent two nights as inpatients. Dose rate at 1 m from all patients was measured approximately 20 and 44 h after the administration of the radioiodine and a whole body scan in the gamma camera was performed approximately 1 week later. With those measurements and by using a model of two compartments the activities in thyroid bed remnants and in the whole body were calculated as a function of time. The integration of both activities yields the corresponding cumulated activities. Absorbed doses to thyroid bed remnants and to the whole body can be calculated following the MIRDOSE method-that is, by multiplying the corresponding cumulated activities by the corresponding S factors. Results: The absorbed doses to thyroid bed remnants calculated in this study fall into a very wide range (13-1161 Gy) and showed the highest correlation factors with the following parameters: the absorbed dose rate to thyroid bed remnants, the cumulated activity in thyroid bed remnants, and the maximum radioiodine uptake in thyroid bed remnants. The absorbed doses to the whole body range from 0.12 to 0.23 Gy. The ablation was successful in all patients, and in spite of the wide range of absorbed doses to thyroid bed remnants obtained, no dose-effect correlation could be obtained. Conclusions: Facing DTC treatments from a dosimetric viewpoint in which a predosimetry to calculate the activity of {sup 131}I to be administered is performed is a subject difficult to handle. This statement is based on the fact that although a very wide range of absorbed doses to thyroid bed remnants was obtained (including several absorbed doses well below some dose

    The inherent diagnostic limitations of thyroid fine needle aspiration (FNA), especially in the "indeterminate" category, can be partially overcome by molecular analyses. We aimed at the identification of miRNAs that could be used to improve the discrimination of indeterminate FNAs. miRNA expression profiling was performed for 17 follicular carcinomas (FTCs) and 8 follicular adenomas (FAs). The microarray results underwent cross-comparison using three additional microarray data sets. Candidate miRNAs were validated by qPCR in an independent set of 32 FTCs and 46 FAs. Sixty-eight differentially expressed miRNAs were identified. Thirteen miRNAs could be confirmed by cross comparison. A two-miRNA-classifier was established improving the diagnostic applicability and resulted in a sensitivity of 82% and a specificity of 49%. We present a classifier that has the potential to be successfully evaluated in cytology material for its capability to discriminate (mutation negative) indeterminate cytologies and thereby improving the pre-surgical diagnostics of thyroid nodules.

    BRAF V600E mutation, RET rearrangements, and RAS mutations are the common genetic alterations in differentiated thyroid carcinomas derived from follicular thyroid cells. However, the relationship between these alterations and iodine intake is still controversial. To clarify the influence of iodine intake on the occurrence of differentiated thyroid carcinomas, we performed molecular analyses for two differentiated carcinomas, papillary thyroid carcinomas (PTCs) and follicular thyroid carcinomas (FTCs), from an iodine-rich country (Japan) and an iodine-deficient country (Vietnam). We examined 120 PTCs (67 Japanese and 53 Vietnamese) and 74 FTCs (51 Japanese and 23 Vietnamese). We carried out allele-specific polymerase chain reaction (AS-PCR) for BRAF V600E, PCR and direct sequencing for RAS mutations (codon 12, 13, and 61 in NRAS, HRAS, and KRAS), and RT-PCR for RET/PTC1 and RET/PTC3. BRAF V600E was present in 55/67 (82.1%) Japanese PTCs and 44/53 (83%) Vietnamese PTCs. RET/PTC1 was identified in only one PTC from each country, and no samples had RET/PTC3. NRAS mutation was found in 17/51 (33.3%) Japanese FTCs and 4/23 (17.4%) Vietnamese FTCs. NRAS mutation was cited in codon 61 (20 cases) and codon 12 (one case). None of FTCs had KRAS or HRAS mutations. There were no significant differences in the prevalence of BRAF V600E, RET/PTC, or RAS mutations between the two countries. Our study showed no differences in genetic alterations of thyroid cancers from iodine-rich and iodine-deficient countries, possibly suggesting that iodine intake might not affect the genetic alterations of differentiated thyroid cancer.

    Background Minimally invasive video-assisted thyroidectomy (MIVAT), the modified Miccoli’s thyroid surgery, is the most widespread minimally invasive technique and has been widely used for treatment of thyroid disease. This study aimed to verify the potential benefits of the modified Miccoli’s thyroid surgery, determine the feasibility of the MIVAT for early-stage differential thyroid carcinoma and evaluate the likelihood of the surgical method as a standard operation for early malignant thyroid carcinoma. Methods A total of 135 patients were retrospectively compared which included two groups of patients: the first group underwent the conventional thyroidectomy; the other group underwent MIVAT. Patients with thyroid nodule smaller than 20 mm and without previous neck surgery were included while those with wide-ranging and distant metastases of cervical tissues, or any suspected thyroid nodal metastases were excluded for analysis. MIVAT and the central compartment (level VI) lymph nodes dissection (LND) were considered as a new treatment method for this retrospective study. In addition to the comparison of surgical outcomes between the new treatment and the conventional thyroid surgery, other surgical parameters including operative time, operative volume of hemorrhage, incisional length, postoperative volume of drainage, length of hospitalization, accidence of hoarse voice, accidence of bucking, accidence of hypocalcemia and peak angle of cervical axial rotation were also compared. Results Out of 135 patients, 111 patients underwent conventional thyroid surgery and 24 patients underwent MIVAT plus level VI LND for treatment of early-stage differential malignant carcinoma. Patients who received the new surgical treatment had significantly shorter incisional length (3.1 cm vs. 6.9 cm, p < 0.0001), shorter operative time (109 min vs. 139 min, p = 0.014) and fewer operative hemorrhage (29.5 ml vs. 69.7 ml, p < 0.0001) when compared to the conventional treatment

    Thyroid cancer is the most common human endocrine malignancy with increasing global incidence. Papillary thyroid carcinomas (PTC) and follicular thyroid carcinomas (FTC) are well-differentiated thyroid cancers (WDTC) accounting for 95% of all thyroid cancer cases, with survival rates of almost 100% when diagnosed early. Since PTC and FTC have different modes of metastasis, they require different treatment strategies. Standard diagnosis by fine needle aspiration with cytopathological examination can be inaccurate in approximately 10-30% of all cases and difficult to definitively classify as WDTC. Currently, there is no single or panel of biomarkers available for thyroid cancer diagnosis and classification. This study identified novel biomarkers for thyroid cancer diagnosis and classification using proteomics, which may be translated into a biomarker panel for clinical application. Two-dimensional SDS-PAGE and mass spectrometry were used to identify potential biomarkers in papillary and follicular thyroid carcinoma cell lines, and the biomarkers were validated in five PTC and five FTC tissues, with their adjacent normal tissues from Thai patients. Eight biomarkers could distinguish PTC from normal tissues, namely enolase 1, triose phosphate isomerase, cathepsin D, annexin A2, cofilin 1, proliferating cell nuclear antigen (PCNA), copine 1 and heat shock protein 27 kDa (HSP27). These biomarkers can also discriminate FTC from normal tissues, except for annexin A2. On the contrary, annexin A2, cofilin 1, PCNA and HSP27 can be used to classify the types of WDTC. These findings have potential for use as a novel multi-marker panel for more accurate diagnosis and classification to better guide physicians on thyroid cancer treatment. Moreover, our results suggest the involvement of proteins in cell growth and proliferation, and the p53 pathway in the carcinogenesis of WDTC, which may lead to targeted therapy for thyroid cancer.

    Differentiated thyroid carcinoma (DTC) has good prognosis but 5% of the patients already have distant metastasis at the diagnosis. Tumour cells can lose their iodine uptake ability and enter a state of dedifferentiation. Treatment for differentiated thyroid carcinoma that is not suitable for the local surgery and unresponsive to radioactive iodine uptake is not always easy for physicians. We present a case of a 64-year-old man who had total thyroidectomy surgery and central lymph node dissection with diagnosis of multinodular goitre disease. Histopathological evaluation was papillary thyroid cancer with tall cell variant. Treatment using 150 mCi radioiodine was administered to the patient three times but could not effect a cure. We performed Ga-68 labelled DOTATE (synthetic somatostatin analogue peptide). This provided a good outcome. As evident from our case, Lu-177 radionuclide labelled synthetic somatostatin analogue peptides have therapeutic effect on radioiodine refractory DTC, as an alternative treatment modality.

    Ectopic thymic tissue can be present in the thyroid gland and a carcinoma showing thymus-like differentiation (CASTLE) may arise from such tissue. We are reported the case of a 26-year-old man with CASTLE, with cervical subcutaneous nodules relapse, who showed a good response to treatment with surgery, chemotherapy and radiotherapy. The problematic aspect of this case was the diagnosis; only on review were we able to make a final diagnosis. CASTLE is a very rare neoplasm. It is important to differentiate this cancer from others tumors such as primary or metastatic squamous cell carcinoma of the head and neck or squamous cell thyroid carcinoma, because the therapy and prognosis are different. Diagnosis is complicated and requires careful histological analysis (CD5- and P63-positive with presence of Hassall’s corpuscles); unfortunately there is no gold standard treatment so, in this case, we administered a sandwich of chemotherapy and radiotherapy.

    Introduction The search for a specific marker that could help to distinguish between differentiated thyroid carcinoma and benign lesions remains elusive in clinical practice. Heparanase (HPSE) is an endo-beta-glucoronidase implicated in the process of tumor invasion, and the heparanase-2 (HPSE2) modulates HPSE activity. The aim of this study was to evaluate the role of heparanases in the development and differential diagnosis of follicular pattern thyroid lesions. Methods HPSE and HPSE2 expression by qRT-PCR, immunohistochemistry evaluation, western blot analysis and HPSE enzymatic activity were evaluated. Results The expression of heparanases by qRT-PCR showed an increase of HPSE2 in thyroid carcinoma (P = 0.001). HPSE activity was found to be higher in the malignant neoplasms than in the benign tumors (P<0.0001). On Western blot analysis, HPSE2 isoforms were detected only in malignant tumors. The immunohistochemical assay allowed us to establish a distinct pattern for malignant and benign tumors. Carcinomas showed a typical combination of positive labeling for neoplastic cells and negative immunostaining in colloid, when compared to benign tumors (P<0.0001). The proposed diagnostic test presents sensitivity and negative predictive value of around 100%, showing itself to be an accurate test for distinguishing between malignant and benign lesions. Conclusions This study shows, for the first time, a distinct profile of HPSE expression in thyroid carcinoma suggesting its role in carcinogenesis. PMID:26488476

    Differentiated thyroid cancer (DTC) is a common and diverse endocrine malignancy. In most patients DTC results in an indolent and curable disease. Nevertheless, disease recurrence rates are relatively high (10%–30%), while 5% of the patients are resistant to conventional treatment and some of these patients are incurable. Over the past 20 years much progress has been made in identifying genetic changes that occur in DTC. In addition, studies aimed to understand the role of these genetic changes in tumorigenesis and their effects on the clinical characteristics of the disease have been conducted. The accrued knowledge has set the stage for development of genetic tests aimed to identify these changes in samples obtained from DTC patients and use this information in the clinical decision process. This paper reviews genetic changes that were identified in DTC, and how the emerging data obtained by genetic testing are currently used to gain key information on the diagnosis, risk stratification, and personalized care of DTC patients.

    Thyroid carcinoma showing thymic-like differentiation (CASTLE) comprises a rare neoplasm of the thyroid gland which arises from ectopic thymic tissue or remnants of brachial pouches. CASTLE is regarded as an indolent neoplasm with a favorable prognosis, irrespective of its metastatic potential. Diagnosis is difficult as clinicopathological features have not been yet well-defined. Radiological findings are not specific and only immunohistochemical positivity for CD5 and CD117 staining is highly suggestive of CASTLE. Despite lack of universally accepted treatment recommendations, the mainstay treatment includes thyroidectomy and systematic lymph node dissection. We report a case of CASTLE tumour with very uncommon characteristics developed in a 76-year-old man, who presented with rapidly deteriorating dyspnea and severe cough, resulting in respiratory failure. At surgery, a suspicious looking tumour arising from the upper pole of the right lobe of the thyroid gland, surrounding the trachea and displacing the right common carotid artery, was identified. The patient underwent en bloc resection of the tumour with the thyroid gland and regional lymph node dissection. This is the first reported case of CASTLE causing tracheal ring fracture.

    Metastatic differentiated thyroid carcinoma (DTC) is an uncommon cause of malignant pleural effusion (MPE) and the characteristics and clinical course have been rarely described. Herein, we report a retrospective review of the clinical course of 18 patients (15 women and 3 men) with MPE from DTC who underwent treatment at our institution between January 2005 and December 2014. MPE from DTC was diagnosed based on cytology and/or level of thyroglobulin in the pleural fluid. Pathologically, papillary carcinoma was found in 16 patients and follicular carcinoma in 2 patients. Median ages at initial diagnosis of DTC and MPE were 64 years (range, 22-79) and 74 years (range, 39-86), respectively. All patients showed radiologically apparent lung metastases, with MPE developing after 0-212 months (median, 25). In 16 patients (88.9%), other coexistent distant metastases at the time of MPE diagnosis were found in the bone (n = 10), brain (n = 5), and skin (n = 2). All patients were treated conservatively with palliative thoracentesis or chest tube drainage with or without pleurodesis. Recurrent MPE after treatment was seen in 9 patients; discharge to home health care after treatment for MPE was possible for 14 patients. The overall survival after initial diagnosis varied considerably from 14 months to 37 years, but the median survival after appearance of MPE was 10 months (range, 1-28). Systemic therapy for iodine-resistant recurrent thyroid disease may need to be considered as a treatment option for patients with MPE. PMID:26655349

    The aim of this study was to evaluate female fertility, carcinogenic, and genetic effects after treatment with {sup 131}I of differentiated thyroid carcinoma. A total of 814 females of child-bearing age were studied. The fertility of 627 females who received {sup 131}I therapy was compared to 187 untreated females. Birth histories of the children born from these women were registered. The carcinogenic effect was evaluated by comparing the incidence of tumors in 730 patients treated with {sup 131}I with an internal control group, as well as with local population incidence. There was no significant difference in the fertility rate, birth weight and prematurity between the two groups. Only one case of a ventricular septal defect was observed in a child born to a woman treated with {sup 131}I. The overall standardized incidence ratio (SIR) of second tumors was 1.19 (95% CI: 0.76-1.77) in patients treated with {sup 131}I. An elevated SIR was registered for salivary gland tumors and melanoma. No case of leukemia was registered. The risk of long-term effects of {sup 131}I treatment of differentiated thyroid carcinoma is quite low. Iodine-131 may be safely used in treating cases with a high risk of recurrence. 35 refs., 7 tabs.

    The study was set out to determine whether characteristic changes in the gene expression profile in papillary thyroid carcinoma (PTC) discovered by microarray assays can be used for conventional molecular diagnosis. Expression levels of five reported to be overexpressed and three underexpressed genes were examined in PTC and normal human tissues by real-time PCR and semi-quantitative duplex PCR. Stepwise logistic regression analysis, duplex PCR data evaluation with recursive partition machine algorithm and hierarchical cluster analysis identified SFTPB (upregulated) and TFF3 (downregulated) gene combination as most favorable for differential molecular diagnosis of PTC. Sensitivity, specificity and accuracy obtained in a series of histologically characterized thyroid tumor and normal tissue samples were 88.9, 96.7 and 94.9%, respectively. Applicability of the method to fine needle aspiration biopsy (FNAB) samples was demonstrated using a collection of needle washouts. In spite individual thyroid tumor and normal tissues as well as FNAB samples displayed a substantial degree of variability in the expression levels of analyzed genes, simultaneous molecular analysis of a panel of optimal markers allows making a high probability predictive estimate and may be considered as an informative method of preoperative PTC diagnosis.

    To evaluate the usefulness and accuracy of Thallium-201 imaging for detecting metastases from thyroid carcinoma, the authors have compared it with radioiodine scans and serum thyroglobulin levels, which are currently the most sensitive technique for detecting and localizing metastases. Of the sixty-nine patients, fifty-three had lymph node, lung and/or bone metastases. All patients were treated for differentiated thyroid carcinoma with various combinations of total thyroidectomy, radioiodine ablation and thyroid hormone. Scintigraphy with Tl-210 chloride was abnormal in 39 of 53 patients (sensitivity 74%), whereas 34 of 47 patients with I-131 (sensitivity 72%). Positive ratio of I-131 was correlated with histological type (93% of follicular type and 48% of papillary), whereas in the results with Tl-201 no correlation with histopathology was seen. In 13 patients with I-131 scan was negative, but in 11 patients Tl-201 scan revealed the presence of non-functioning metastases. The positive ratio of Tl-201 scans was correlated well with the size of metastases tumors (P<0.005). Of 43 patients with metastases whose thyroglobulin levels (Tg) were measured by radioimmunoassay, Tg were elevated more than 20ng/ml in 37 (86%); the remaining 14% were below 20 ng/ml in spite of having functioning metastases. These patients were subsequently to have elevation of Tg (>80ng/ml) during hypothyroidism. These results indicate Tl-201 scans correlate with serum thyroglobulin levels and have the added advantage of detecting and localizing non-functioning metastases which would not be detected by I-131 scans.

    The value of hTg-measurements are still discussed controversially. Also, there are no tables with sensitivity/specificity pairs for different cutoffs, since valuable information is lost by presenting only one sensitivity/specificity pair. Therefore, we wanted to determine these values for hTg by a ROC-analysis. Inclusion criteria were: (a) differentiated thyroid carcinoma (papillary or follicular), (b) no thyroid-rest after primary therapy (e.g. no detectable hTg and nc iodine accumulating foci in iodine-whole body scan), (c) no detectable hTg- antibodies, (d) an observation period of at least 1 year, hTg was determined by TG-RIA and hTg-antibodies by IMMUtest anti-Tg. Recurrence was proven by iodine-whole-body scans under maximal endogenous TSH-stimulation or by histology. Sensitivity and specificity were calculated for different hTg-cutoffs. During 10/80 and 10/89 93 patients met these criteria. There were 71 female and 22 male with a mean age of 48.6 {plus_minus} 16.3 years. 51 patients had papillary carcinomas, 42 patients follicular carcinomas. The observation period was 78.4 {plus_minus} 40.9 months. In these 93 patients there were 16 recurrences during the observation period. Sensitivity/specificity pairs for different cutoffs are given. These sensitivity/specificity pairs avoid the reduction of the original continuous data to a Yes/No decision. The knowledge of these data and of the ROC-curve could improve the intuitive rating of a laboratory result by the physician.

    Differentiated thyroid carcinoma (DTC) is a common malignancy. The general treatments are thyroidectomy of the affected lobe along with lymphadenectomy. However, bone metastasis is rare in DTC compared with other malignancies and the management of metastasis foci is still controversial. Here we present a case of follicular thyroid carcinoma with the 6th cervical vertebra body metastasis successfully treated by total thyroidectomy, cervical corpectomy, and internal fixation, followed by hormone replacement therapy and radioiodine therapy. Eleven additional patients diagnosed as thyroid carcinoma with bone metastasis collected from Chinese literature between January 1996 and December 2013 were also reviewed. The mean age of the 12 patients at presentation was (53.9±9.2) years (rang, 42–72 years) and the male to female ratio was 1:2. Nine cases received total/near-total thyroidectomy or lobectomy while the other three patients refused for personal reasons. The interventions for bone metastasis were one-stage operation (9/12), I131 adjuvant therapy (3/12), chemotherapy (1/12), and no intervention (1/12). During the follow-up, two patients died of metastatic carcinoma recurrence, one died of multiple organ metastasis, and one with an unknown reason. We conclude that the management of thyroid carcinoma with bone metastasis needs multidisciplinary cooperation. Surgical resection is still the first choice for cure, while the combined one-stage operation on the primary and metastatic sites followed by hormone replacement therapy and radioiodine therapy is an applicable treatment.

    Medullary thyroid carcinoma (MTC) is a neuroendocrine cancer of thyroid C-cells, for which few treatment options are available. We have recently reported a role for cyclin-dependent kinase 5 (CDK5) in MTC pathogenesis. We have generated a mouse model, in which MTC proliferation is induced upon conditional overexpression of the CDK5 activator, p25, in C-cells, and arrested by interrupting p25 overexpression. Here, we identify genes and proteins that are differentially expressed in proliferating versus arrested benign mouse MTC. We find that downstream target genes of the tumor suppressor, retinoblastoma protein, including genes encoding cell cycle regulators such as CDKs, cyclins and CDK inhibitors, are significantly upregulated in malignant mouse tumors in a CDK5-dependent manner. Reducing CDK5 activity in human MTC cells down-regulated these cell cycle regulators suggesting that CDK5 activity is critical for cell cycle progression and MTC proliferation. Finally, the same set of cell cycle proteins was consistently overexpressed in human sporadic MTC but not in hereditary MTC. Together these findings suggest that aberrant CDK5 activity precedes cell cycle initiation and thus may function as a tumor-promoting factor facilitating cell cycle protein expression in MTC. Targeting aberrant CDK5 or its downstream effectors may be a strategy to halt MTC tumorigenesis. PMID:25900242

    Prophylactic central neck dissection (pCND) in differentiated thyroid carcinoma (DTC) is one of the most controversial surgical subjects in recent times. To date, there is little evidence to support the practice of pCND in patients with DTC undergoing total thyroidectomy. Although the recently revised American Thyroid Association (ATA) guideline has clarified many inconsistencies regarding pCND and has recommended pCND in “high-risk” patients, many issues and controversies surrounding the subject of pCND in DTC remain. The recent literature has revealed an insignificant trend toward lower recurrence rate in patients with DTC who undergo total thyroidectomy and pCND than those who undergo total thyroidectomy alone. However, this was subjected to biases, and there are concerns whether pCND should be performed by all surgeons who manage DTC because of increased surgical morbodity. Performing a unilateral pCND may be better than a bilateral pCND given its lower surgical morbidity. Further studies in this controversial subject are much needed. PMID:21977029

    Since thallium-201 imaging has been reported as a potential means of follow-up of patients with differentiated thyroid carcinoma (DTC) during ongoing thyroid suppression therapy, the authors evaluated the diagnostic sensitivity of this procedure in 31 patients known to have metastases or local recurrence. Among 51 tumor sites /sup 201/TI imaging had a detection rate of 45% whereas 84% was noted for imaging with /sup 131/I administered in therapeutic doses. Thus, even though the effectiveness of the two radionuclides is not strictly comparable due to the difference in the administered doses, Thallium imaging cannot be recommended as the only modality for the follow-up of patients with DTC. Six of the eight tumor sites negative with /sup 131/I were positive with /sup 201/TI (especially metastatic cervico-mediastinal lymph nodes). So /sup 201/TI imaging may particularly be helpful in localizing metastases or recurrences in patients with a negative /sup 131/I scan and abnormal levels of serum thyroglobulin.

    A questionnaire administered in 2009 found that members of the Korean Association of Thyroid-Endocrine Surgeons (KATES) favored more aggressive treatment of well-differentiated thyroid carcinoma (WDTC) than physicians from other countries. This study assessed the changes in practical management of WDTC in Korea from the previous survey. Questionnaires were sent by e-mail to KATES members. A total of 101 members completed the questionnaire. Their responses were compared with response for the 2009 survey. Of the respondents, 53.5% and 80.2% indicated that they would perform fine-needle aspiration cytology on nodules that were <0.5 cm and 0.5-1.0 cm in diameter, respectively. If the cytology was positive, a large number of respondents favored surgical treatment, regardless of tumor size. Compared with the 2009 survey, a slightly higher percentage favored observation for patients with tumors that were <0.5 cm in diameter, and a larger percentage recommended less-than-total thyroidectomy for patients with T1 cancers. Respondents in 2014 favored aggressive lymph node dissection less, irrespective of tumor size, preferring short-term treatment with thyroid stimulating hormone suppressors. The percentage preferring postoperative high-dose radioactive iodine therapy slightly increased, whereas the percentage favoring external irradiation decreased, in 2014 compared with 2009. The management of Korean patients with WDTC changed from 2009 to 2014. In 2009, Korean respondents favored more aggressive treatment of WDTC compared with respondents from other countries. In 2014, however, Korean respondents favored a more conservative approach, especially in patients with microcarcinomas. PMID:26961223

    The aim of the present study was to assess whether {sup 131}I therapy for differentiated thyroid carcinoma (DTC) can affect endocrine testicular function. Serum follicle-stimulating hormone (FSH) and testosterone (T) concentrations were measured in 103 patients periodically submitted for radioiodine therapy for residual or metastatic disease. Mean follow-up was 93.7{+-}54 mo (range 10-243 mo). Mean FSH values in {sup 131}I-treated patients tested after their last treatment were 15.3{+-}9.9 mU/ml, significantly higher than those of 19 untreated patients (6.5{+-}3.1 mU/ml). Considering the mean +3 s.d. FSH of untreated subjects as the upper limit of normal range, 36.8% of the patients had an abnormal increase in serum FSH. Longitudinal analysis performed in 21 patients showed that the behavior of FSH in response to {sup 131}I therapy was not universal. Six patients had no change or a slight increase in serum FSH after {sup 131}I administration; eleven patients had a transient increase above normal values 6-12 mo after {sup 131}I treatment, with return to normal levels in subsequent months. The administration of a second dose was followed by a similar increase in FSH levels. Finally, four patients, followed for a long period of time and treated with several {sup 131}I doses, showed a progressive increase in serum FSH, which eventually became permanent. Semen analysis, performed in a small subgroup of patients, showed a consistent reduction in the number of normokinetic sperm. No change was found in serum T levels between treated and untreated patients. The results indicate that {sup 131}I therapy for thyroid carcinoma is associated with transient impairment of testicular germinal cell function. The damage may become permanent for high-radiation activities delivered year after year and might pose a significant risk of infertility. 14 refs., 8 figs., 1 tab.

    Nine hundred thirty-two patients with papillary and follicular thyroid carcinomas were seen at the Departments of Medicine, Surgery, and Radiology of the University of Essen, Essen, Germany, between 1970 and 1986. In addition to standard treatment by surgery, radioactive iodine and medical thyroid stimulating hormone (TSH) suppression, 346 patients had received conventional external irradiation to the neck before referral to our institutions, whereas 586 patients had not received radiotherapy. From the follow-up data of these patients, survival rates were calculated separately for tumor Stages T1 (n = 203), T2 (n = 552), and T3/T4 (n = 277) using life-table analysis. Distribution of risk factors (histologic type of tumor, grading of malignancy, presence of distant metastases, age and sex) was similar in all groups with the one exception, that the radiotherapy patients with Stage T3/T4 were older. There was no significant difference in the life expectancy of irradiated and not irradiated patients by Breslow and Mantel-Cox tests. In Stages T1, T2, and T3/T4, 75% of the radiotherapy patients survived for 10.6 +/- 0.32, 11.5 +/- 0.61, and 6.71 +/- 0.85 years, respectively; the figures for the nonirradiated patients were 9.4 +/- 0.17, 10.8 +/- 0.37, and 6.26 +/- 0.51 years, respectively. When survival rates were calculated separately for patients with Stage T3/T4 older and younger than 40 years, there was no obvious effect of radiotherapy in the younger group, whereas in the older patients, improvement of survival by radiation just failed to reach statistical significance. In conclusion, this retrospective analysis failed to prove that survival is prolonged in patients with differentiated carcinoma by administration of conventional external radiotherapy after surgery. A benefit to older patients with locally advanced tumors has still to be demonstrated.

    Differentiated thyroid carcinoma (TC) is threefold more common in women than in men and, therefore, a role of female hormones in the etiology of differentiated TC has been suggested. We assessed these hypotheses in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Among 345,157 women (mean age 51) followed for an average of 11 years, 508 differentiated TC cases were identified. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression models. No significant associations were observed between differentiated TC risk and number of pregnancies, breast feeding, menopausal status, and age at menarche and at menopause. Significant associations were found with history of infertility problems (HR 1.70; 95% CI 1.12-2.60), a recent pregnancy (HR for ≤ 5 vs. >5 years before recruitment 3.87; 95% CI 1.43-10.46), menopause type (HR for surgical vs. natural menopause: 2.16; 95% CI 1.41-3.31), oral contraceptive (OC) use at recruitment (HR: 0.48; 95% CI 0.25-0.92) and duration of OC use (HR for ≥ 9 vs. ≤ 1 year: 0.66; 95% CI: 0.50-0.89). An increased risk was also found with hormone replacement therapy use at recruitment (HR = 1.30, 95% CI 1.02-1.67), but this was not significant after adjustment for type of menopause (HR = 1.22, 95% CI 0.95-1.57). Overall, our findings do not support a strong role of reproductive and menstrual factors, and female hormone use in the etiology of differentiated TC. The few observed associations may be real or accounted for by increased surveillance in women who had infertility problems, recent pregnancies or underwent surgical menopause. PMID:25041790

    BACKGROUND This study aimed to investigate the parameters influencing the effectiveness of first 131I thyroid remnant ablation and then 131I treatment of metastatic lesions in children and adolescents with differentiated thyroid carcinoma (DTC). MATERIAL AND METHODS A total of 88 children and adolescents with DTC were divided into 2 groups: 56 in the complete-ablation group and 32 in the incomplete-ablation group for the first 131I ablation; 32 in the incomplete-ablation group were further divided: 19 in the complete-remission group and 13 in the incomplete-remission group for subsequent 131I treatment of metastatic lesions. Influential parameters were analyzed using t test, t' test, rank-sum test, χ2-test, and Fisher exact test, and logistic regression analysis was performed. Radioactive iodine uptake (RAIU), lymph node metastases, and pulmonary metastases were selected as influential parameters. RESULTS After logistic regression analysis, RAIU, only lymph node metastases, and pulmonary metastasis were significantly associated with the complete-ablation rate. High levels of RAIU and serum thyroglobulin (Tg) were not conducive to disease remission after subsequent 131I treatment of metastatic lesions. The remission rate of patients with pulmonary metastasis was lower than the rate of patients with lymph node metastases or no metastases. CONCLUSIONS Results demonstrated that a high remission rate is associated with low postoperative RAIU and Tg. Lymph node metastasis and pulmonary metastasis reduce the complete-remission rate of first 131I ablation therapy. Pulmonary metastasis reduces the remission rate of subsequent 131I treatment. Also, 131I treatment for pediatric DTC with pulmonary metastasis achieved progression-free survival. PMID:27576533

    The objective of the study was to identify microRNAs (miRs) characteristic for follicular thyroid carcinoma (FTC) and to define their role in tumorigenesis. A miR-microarray study was conducted to identify miRs differentially expressed between FTCs and their surrounding tissues. Selection was further reinforced by a literature review. Four miRs were selected and confirmed by RT-qPCR: miR-146b, -183, -221 were up-regulated, whereas miR-199b down-regulated in FTCs. The influence of these miRs on cell proliferation, cell cycle, apoptosis and migration was studied in HTori and FTC-133 cells. Functional characterization suggests an impact of miR-183 and miR-146b in FTC development. Overexpression of both miRs significantly induces migration. Moreover, overexpression of miR-183 significantly represses apoptosis. MiR-199b and -221 do not have significant effects on proliferation, cell cycle, apoptosis or migration in HTori and FTC-133 cells. Our data suggest that miR-146b and miR-183 may influence FTC development through the induction of migration and apoptosis inhibition. PMID:24631480

    Metastatic carcinoma to the thyroid gland rarely is encountered in clinical practice; however, autopsy series have shown that it is not a rare occurrence. A case of adenocarcinoma of the colon with metastases to the thyroid is reported. A review of the literature reveals that melanoma, breast, renal, and lung carcinomas are the most frequent tumors to metastasize to the thyroid. Metastatic disease must be considered in the differential diagnosis of cold nodules on radionuclide thyroid scans, particularly in patients with a known primary.

    Background Common polymorphisms of the vitamin D receptor gene have been reported to affect the risk of breast, colon, prostate, and differentiated thyroid cancer (DTC), but polymorphisms within the genes of vitamin D metabolizing enzymes have not been studied in DTC. The aim of the present study was to investigate the genes for vitamin D enzymes in patients with DTC and healthy controls (HC) as well as the vitamin D (25-hydroxyvitamin D3, and 1,25-hydroxyvitamin) status. Methods German patients (n=253) with DTC (papillary thyroid carcinoma [PTC] and follicular thyroid carcinoma [FTC]) and HC (n=302) were genotyped for polymorphisms within the vitamin D metabolizing enzymes such as 25-hydroxylase (CYP2R1[rs12794714, rs10741657]), 25-hydroxyvitamin D-1α-hydroxylase (CYP27B1[rs10877012, rs4646536]), and 25-hydroxyvitamin D 24-hydrolase (CYP24A1[rs927650, rs2248137, rs2296241]). Furthermore, the 25-hydroxyvitamin D3 [25(OH)D3] and 1,25-hydroxyvitamin [1,25(OH)2D3] plasma levels were measured by a radioimmunoassay. Results There was no difference in the genotypes; however, the CYP24A1 haplotype analysis showed that rs2248137C/rs2296241A (13.1% vs. 19.1%; corrected p [pc]=0.04) was less frequent in the PTC, whereas the haplotypes rs2248137C/rs2296241G (56.0% vs. 41.9%; pc=0.03), rs927650C/rs2296241G (22.5% vs. 8.4%; pc=1.6×10−3), and rs927650C/rs2248137C/rs2296241G (21.1% vs. 7.3%; pc=1.5×10−3) were more frequent in the FTC compared with HC. Furthermore, if patients and controls were grouped according to four 25(OH)D3 categories (severely deficient, deficient, insufficient, and sufficient), then the patients with both DTC subtypes had significantly lower levels of circulating 1,25(OH)2D3, especially in the group with a deficient 25(OH)D3 status compared with the controls. Although the polymorphisms showed no differences stratified for the four 25(OH)D3 categories, the activation status by 1,25(OH)2D3 differed significantly depending on the genotypes of the

    Radioiodine scintigraphy influences staging and treatment in patients with differentiated thyroid carcinoma. The limit of detection for fractional uptake in an iodine avid focus in a scintigraphic image was determined from the number of lesion net counts and the count density of the tissue background. The count statistics were used to calculate the diagnostic activity required to elevate the signal from a lesion with a given uptake significantly above a homogeneous background with randomly distributed counts per area. The dependences of the minimal uptake and the minimal size of lesions visible in a scan on several parameters of influence were determined by linking the typical biokinetics observed in iodine avid tissue to the lesion mass and to the absorbed dose received in a radioiodine therapy. The detection limits for fractional uptake in a neck lesion of a typical patient are about 0.001% after therapy with 7000 MBq, 0.01% for activities typically administered in diagnostic assessments (74-185 MBq), and 0.1% after the administration of 10 MBq I-131. Lesions at the limit of detection in a diagnostic scan with biokinetics eligible for radioiodine therapy are small with diameters of a few millimeters. Increasing the diagnostic activity by a factor of 4 reduces the diameter of visible lesions by 25% or about 1 mm. Several other determinants have a comparable or higher influence on the limit of detection than the administered activity; most important are the biokinetics in both blood pool and target tissue and the time of measurement. A generally valid recommendation for the timing of the scan is impossible as the time of the highest probability to detect iodine avid tissue depends on the administered activity as well as on the biokinetics in the lesion and background in the individual patient.

    We aimed to evaluate the diagnostic utility of the novel immunohistochemical marker TROP-2 on thyroid specimens (226 tumours and 207 controls). Whole slide immunohistochemistry was performed and scored by automated digital image analysis. Non-neoplastic thyroid, follicular adenomas, follicular carcinomas, and medullary carcinomas were negative for TROP-2 immunostaining. The majority of papillary thyroid carcinoma (PTC) specimens (94/114, 82.5%) were positive for TROP-2; however, the pattern of staining differed significantly between the histopathological variants. All papillary microcarcinomas (mPTC), PTC classic variant (PTC cv), and tall cell variant (PTC tcv) were TROP-2 positive, with mainly diffuse staining. In contrast, less than half of the PTC follicular variant specimens were positive for TROP-2, with only focal immunoreactivity. TROP-2 could identify PTC cv with 98.1% sensitivity and 97.5% specificity. ROC curve analysis found that the presence of >10% of TROP-2 positive cells in a tumour supported a diagnosis of PTC. The study of intratumoural heterogeneity showed that low-volume cytological samples of PTC cv could be adequately assessed by TROP-2 immunostaining. The TROP-2 H-score (intensity multiplied by proportion) was significantly associated with PTC variant and capsular invasion in encapsulated PTC follicular variant (p<0.001). None of the baseline (age, gender) and clinical (tumour size, nodal disease, stage) parameters were correlated with TROP-2 expression. In conclusion, TROP-2 membranous staining is a very sensitive and specific marker for PTC cv, PTC tcv, and mPTC, with high overall specificity for PTC. PMID:27311870

    Follicular carcinomas are rare thyroid malignancies that are difficult to diagnose preoperatively. Fine needle aspiration is an excellent diagnostic tool and should be the initial step in managing the solitary thyroid nodule. Follicular carcinoma cannot be diagnosed with certainty by cytologic features alone; the diagnosis rests on the histologic findings of blood vessel or tumor capsule invasion. Surgical resection is the primary option for treatment. The extent of thyroidectomy for optimal survival outcome has not been determined scientifically. The outcome is excellent in minimally invasive follicular carcinoma with lobectomy and isthmusectomy; it is difficult to argue that total thyroidectomy is necessary. In a low risk prognostic group, for tumors other than minimally invasive carcinoma, lobectomy and isthmusectomy or total thyroidectomy can be justified. However, if total thyroidectomy can be done safely with a minimum of complications, then it has definite advantages for staging, postoperative surveillance, treatment, and possibly a lower recurrence rate and better survival rate. For all patients at high risk of recurrence, total thyroidectomy is preferred. PMID:12074771

    Despite the fact that differentiated thyroid carcinoma (DTC) is not classified as a neuroendocrine tumor, there is an increasing interest for the use of somatostatin receptors scintigraphy (SRS) in this disease. We evaluated SRS in DTC patients having no or a poor radioiodine uptake at the level of their tumor sites. Nine patients (pts) (7 men, 2 women; aged from 52 to 65 years) were previously treated (surgery of the primary: 9/9pts; followed by cervical radiotherapy: 4/9pts; radioiodine therapy: 8/9pts; surgery or radiotherapy to bone metastases: 2/9 pts) for DTC (papillary form: 6 pts; follicular; 1 pts; insular: 2 pts). They were explored by conventional imaging modalities (CIM) including Tc-99m MDP bone scans. High activity radioiodine scans were obtained 5 days after I-131 therapy. SRS was carried out during thyroxine therapy using Indium-111 pentetreotide (120 MBq) with imaging at 4 and 24 hours after injection (whole body scans and, when necessary, SPECT). Thyroglobulin blood level ranged from 120 to 60,000ng/ml. SRS was positive at the level of all tumor sites in 8/9 pts; radioiodine scans were negative in 4 pts (1pt with an insular DTC, 3 pt with a papillary DTC), slightly positive in 2 pts (papillary DTC), positive only on part of tumor sites in 1 pts (insular DTC), positive in 1 pt (follicular DTC) and not done in 1 pt. SRS demonstrated 3 new tumor sites (1 to bone, 1 to lung and 1 to mediastinal lymph nodes) in 2 pts; in an other pt, SRS clarified out a doubtful Tc-99m bone scan result and led to definitive confirmation of bone metastases. We had only 1 false negative result in 1 pt having pulmonary metastases (slightly positive radioiodine scan) which had been stable in size on CT for 6 years. These results indicate that, when radioiodine scans are ineffective, SRS is a powerful modality for imaging DTC tumor sites.

    The effect of subclinical hyperthyroidism on bone mineral density is controversial and could be significant in patients with differentiated thyroid carcinoma who receive suppressive doses of levothyroxine (LT4). To ascertain whether prolonged treatment with LT4 to suppress thyrotropin had a deleterious effect on bone mineral density and/or calcium metabolism in patients thyroidectomized for differentiated thyroid cancer we have performed a cross-sectional study in a group of 88 women (mean +/- SD age: 51 +/- 12 years) treated with LT4 after near-total thyroidectomy and in a control group of 88 healthy women (51 +/- 11 years) matched for body mass index and menopausal status. We determined calcium metabolism parameters, bone turnover marker N-telopeptide and bone mass density by dual-energy X-ray absorptiometry. No differences were found between patients and controls in calcium metabolism parameters or N-telopeptide except for PTH, which was significantly increased in controls. No differences were found between groups in bone mineral density in femoral neck (0.971 +/- 0.148 gr/cm(2) vs 0.956 +/- 0.130 gr/cm(2) in patients and controls respectively, P = 0.5). In lumbar spine, bone mineral density values were lower in controls than in patients (1.058 +/- 0.329 gr/cm(2) vs 1.155 +/- 0.224 gr/cm(2) respectively, P < 0.05). When premenopausal (n = 44) and postmenopausal (n = 44) patients were compared with their respective controls, bone mineral density was similar both in femoral neck and lumbar spine. The proportion of women with normal bone mass density, osteopenia and osteoporosis in patient and control groups was similar in pre- and postmenopausal women. In conclusion, long-term suppressive LT4 treatment does not appear to affect skeletal integrity in women with differentiated thyroid carcinoma. PMID:16322336

    Medullary thyroid carcinoma (MTC) is developed from thyroid C cells that secrete calcitonin (CT). MTC represents 5-10% of thyroid cancers with a 1-2% incidence in nodular thyroid diseases. Diagnosis is usually made by a solitary nodule often associated to nodal metastasis and confirmed by a high basal CT level which represents its biological marker. MTC may present as a sporadic form and in about 30% of case as a familial form as a part of multiple endocrine neoplasia syndrome, an hereditary dominant inherited disease related to germline mutation of the proto-oncogene RET. Both biological (CT) and genetic (RET) markers allows the optimal diagnosis and treatment of MTC; the former allows screening and early diagnosis of MTC by routinely CT measurements in nodular thyroid diseases that make the adequate and complete surgery required to be performed. The former leads to diagnose familial MTC and to identify at risk subjects in whom early or prophylactic surgery may be performed. Treatment of MTC is based on the complete surgical resection: total thyroidectomy associated to central and laterocervical nodal dissection. For locally advanced or metastatic MTC, complete cervical surgery is required and needs to be associated to other systemic treatments: as chemotherapy is not very efficient, radioimmunotherapy and RET target gene therapy (mainly tyrosine kinase inhibitors) appears as possible valuable therapeutic options for the future. Prognosis of MTC is mainly related to both the stage of the disease and the extend of the initial surgery. Ten-year survival is about 80% when the patients are not surgically cured and reaches 95% when the biological marker CT is normalized after surgery. PMID:17572372

    Differentiated thyroid carcinoma (DTC) is generally indolent in nature and, even though it metastasizes to distant organs, the prognosis is normally excellent. In contrast, the overall survival (OS) of patients with radioactive iodine (RAI)-refractory and progressive metastases is dire, because no effective therapies have been available to control the metastatic lesions. However, recently, administration of tyrosine-kinase inhibitors (TKIs) has become a new line of therapy for RAI-refractory and progressive metastases. Previous studies have reported significant improvement regarding the progression-free survival rates of patients with metastatic lesions. However, TKIs cause various severe adverse events (AEs) that damage patients' quality of life and can even be life-threatening. Additionally, metastatic lesions may progress significantly after stopping TKI therapy. Therefore, it is difficult to determine who is a candidate for TKI therapy, as well as how and when physicians start and stop the therapy. The present review, created by Committee of pharmacological therapy for thyroid cancer of the Japanese Society of Thyroid Surgery (JSTS) and the Japan Association of Endocrine Surgeons (JAES) describes how to appropriately use TKIs by describing what we do and do not know about treatment using TKIs.

    Imaging plays an important role in early detection and staging of medullary thyroid carcinoma (MTC) as well as in follow-up to localize early recurrence. MTC is a rare, calcitonin-secreting thyroid malignancy often diagnosed by ultrasound and calcitonin screening as part of the routine workup for any thyroid nodule. If calcitonin is elevated, imaging studies are needed for preoperative staging, which dictates surgical management. This can be done by ultrasound of the neck and abdomen. Computed tomography (CT) or magnetic resonance imaging (MRI) studies for more distant disease are done preoperatively if calcitonin levels are higher than 500 pg/ml. Neither FDG-PET/CT nor F-DOPA-PET/CT are used routinely for preoperative staging but may contribute in doubtful individual cases. Postoperative elevated calcitonin is related to persistence or recurrence of MTC. Imaging studies to localize tumor tissue during postoperative follow-up include ultrasound, CT, MRI as well as PET studies. They should be used wisely, however, since treatment consequences are often limited, and even patients with persistent disease may survive long enough to accumulate significant radiation doses. Imaging studies are also useful for diagnosis of associated components of the hereditary MTC such as pheochromocytoma and primary hyperparathyroidism (pHPT). PMID:26494385

    Medullary thyroid carcinoma (MTC), which originates from thyroid parafollicular C cells, accounts for 3 to 5% of thyroid malignancies. MTC occurs either sporadically or in an inherited autosomal dominant manner. Hereditary MTC occurs as a familial MTC or as a part of multiple endocrine neoplasia (MEN) type 2A and B syndromes. A strong genotype-phenotype correlation has been observed between hereditary MTC and germ-line “gain of function” mutations of the RET proto-oncogene. Most cases of pediatric MTC are hereditary whereas sporadic MTC is rare in children and is usually diagnosed in adults. Therefore, MTC in children is most often diagnosed in the course of a familial genetic investigation. The standard treatment of MTC mainly requires surgery involving total thyroidectomy and central neck node dissection before extrathyroidal extension occurs. To prevent MTC development in hereditary syndromes, prophylactic thyroidectomy is performed in presymptomatic patients. An appropriate age at which the surgery should take place is determined based upon the data from genotyping, serum calcitonin measurements, and ultrasonography. For the treatment of advanced MTC cases, the broad spectrum receptor tyrosine kinase inhibitors vandetanib and cabozantinib, which also inhibit RET, are used although they are not always effective.

    Medullary thyroid carcinoma accounts for 2% to 5% of thyroid malignancies, of which 75% are sporadic and the remaining 25% are hereditary and related to multiple endocrine neoplasia type 2 syndrome. Despite a genotype-phenotype correlation with specific germline RET mutations, knowledge of pathways specifically associated with each mutation and with non-RET-mutated sporadic MTC remains lacking. Gene expression patterns have provided a tool for identifying molecular events related to specific tumor types and to different clinical features that could help identify novel therapeutic targets. Using transcriptional profiling of 49 frozen MTC specimens classified as RET mutation, we identified PROM1, LOXL2, GFRA1, and DKK4 as related to RET(M918T) and GAL as related to RET(634) mutation. An independent series of 19 frozen and 23 formalin-fixed, paraffin-embedded (FFPE) MTCs was used for validation by RT-qPCR. Two tissue microarrays containing 69 MTCs were available for IHC assays. According to pathway enrichment analysis and gene ontology biological processes, genes associated with the MTC(M918T) group were involved mainly in proliferative, cell adhesion, and general malignant metastatic effects and with Wnt, Notch, NFκB, JAK/Stat, and MAPK signaling pathways. Assays based on silencing of PROM1 by siRNAs performed in the MZ-CRC-1 cell line, harboring RET(M918T), caused an increase in apoptotic nuclei, suggesting that PROM1 is necessary for survival of these cells. This is the first report of PROM1 overexpression among primary tumors. PMID:23201134

    Differentiated thyroid carcinoma (DTC) generally has a favorable outcome. Thyroid disease, treatments, stress, and comorbidity can compromise health-related quality of life (QoL) and indirectly weigh upon the outcome. From 2004 to 2008, we evaluated QoL longitudinally in 128 DTC subjects. During scheduled examinations, subjects were asked to undergo a semi-structured psychiatric interview and five rated inventories. The same examination was conducted in 219 subjects after surgery for benign thyroid pathology. Low scores represent a better QoL. DTC and control subjects were similar in terms of age, male/female ratio, concomitant psychopharmacological treatments, and frequency of psychiatric diseases. In DTC subjects, Billewicz scale (BS) scores showed an increasing trend over time, especially among females. The ad hoc thyroid questionnaire (TQ) scores were similar in both groups and did not change over time, but at the end of the study ad hoc TQ and BS were significantly related. Ad hoc TQ scores were also related to age on entry to the study. In both male and female DTC subjects, Hamilton’s tests for anxiety (HAM-A), but not for depression (HAM-D), showed an improving trend. At the end of the study, HAM-A and HAM-D scores were comparable to those of the control group. HAM-A and HAM-D were both positively correlated with the stage of cancer and the time between diagnosis and treatment. Only HAM-D correlated with age on entry to the study. Kellner symptom questionnaire (KSQ) item scores were higher in DTC subjects than in controls. The change over time in the items including anxiety, somatization, depression, and hostility was significant. Somatization and hostility were more significantly reduced in DTC females than in DTC males. Hostility scores were significantly lower in DTC subjects than in controls at the end of the study. Somatization and depression were significantly related to staging on diagnosis and age on entry to the study. Our study confirms a wide

    Patients with differentiated thyroid carcinoma (DTC) are commonly treated long-term with thyrotropin (TSH)- suppressive thyroxine replacement therapy resolving in a state of subclinical hyperthyroidism. The relationship between subclinical hyperthyroidism and osteoporosis is not clear. In this review, we systematically selected and analyzed 21 studies addressing this issue. Although multiple methodological differences between studies prevented a structured meta-analysis, our data suggest that postmenopausal women with subclinical hyperthyroidism are most at risk, whereas no increased risk was observed in men and premenopausal women. Based on these findings we believe that measurement of bone mineral density is recommended in postmenopausal women with DTC starting TSH suppressive therapy. This should be subsequently regularly measured to enable timely intervention with bone protective agents. PMID:16839260

    Fifty-eight cases of pulmonary metastases (PM) from 831 cases of differentiated thyroid carcinoma (DTC) were studied. PM were found in about 10% of follicular and 5% of papillary tumors. /sup 131/I uptake was found in 55% of the cases, irrespective of histology. Twenty-one patients were treated by /sup 131/I only and 12 were cured. Micronodular metastases, 92% papillary, with 86% positive /sup 131/I uptake and 77% 8-year survival rate, are the most favorable forms. In others the influence of PM size/age, uptake, delay of appearance, presence of cervical or mediastinal lymph nodes is discussed. Occurrence of late PM according to treatment of the primary tumor was 1.3% thyroidectomy + /sup 131/I; 3% thyroidectomy; 5% partial thyroidectomy + /sup 131/I; 11% partial thyroidectomy only. Thus prevention in DTC of severe PM (28% 8-year survival rate) can best be achieved by complete thyroidectomy + /sup 131/I ablation dose.

Mean age at diagnosis was 61 years. The manifestation of bone metastases was the presenting symptom in 18 patients (60%). Treatment included total thyroidectomy, levothyroxine sodium therapy, and radioactive iodine treatments. Twenty-seven patients had bone metastases from the initial observation, with 44 sites involved. Of the sites, 27 (61%) were shown both on iodine 131 whole-body scan (WBS) and on x-ray film, 11 (25%) only on WBS, and six (14%) only on x-ray film. Multiple involvement was observed in 11 patients. The radiologic appearance was invariably osteolytic. Serum thyroglobulin was elevated in all patients. After radioactive iodine, no WBS+/X-ray+ metastases showed a complete response, although a sclerotic border was noted in several cases, whereas six WBS+/X-ray- lesions were no longer detectable by WBS. Treatment with radioactive iodine and bone surgery resulted in a complete cure in three patients and in a reduction of tumor mass in three. Twenty-one (70%) of the patients died of thyroid cancer after a mean survival of 86 months. Of the nine patients still alive, two are free of disease, three have a good quality of life, and four have severe disability.

    The thyroid gland is a rare site for cancer metastasis. We report a 75-year-old man who was referred with a history of hematuria and generalized bone pain for the past few months. He had a past history of partial left lobe thyroidectomy for follicular adenoma. Subsequently he was referred for a thyroid mass and a subtotal thyroidectomy showed a poorly-differentiated carcinoma. On the latest admission, the patient underwent resection of a bladder tumour with malignant histology and an immunohistochemical profile of CK7+/CK20+/34 Beta E12+/CEA-/PSA-. Re-examination of thyroid sections with immunohistochemical stains revealed the malignant cells to be CK7+/CK20+/34 Beta E12+/CEA-/TTF1-. The findings were compatible with metastasis of the bladder transitional cell carcinoma to the thyroid gland.Scans revealed multiple liver and bone metastases. The patient died 2 months after the diagnosis. PMID:27126668

    Dedifferentiated thyroid carcinoma (DTC) with the loss of radioiodine uptake (RAIU) is often observed in clinical practice under radioiodine therapy, indicating the challenge for poor prognosis. MicroRNA (miRNA) has emerged as a promising therapeutic target in many diseases; yet, the role of miRNAs in RAIU has not been generally investigated. Based on recent studies about miRNA expression in papillary or follicular thyroid carcinomas, the expression profiles of several thyroid relative miRNAs were investigated in one DTC cell line, derived from normal DTC cells by radioiodine treatment. The top candidate miR-146b, with the most significant overexpression profiles in dedifferentiated cells, was picked up. Further research found that miR-146b could be negatively regulated by histone deacetylase 3 (HDAC3) in normal cells, indicating the correlation between miR-146b and Na{sup +}/I{sup −} symporter (NIS)-mediated RAIU. Fortunately, it was confirmed that miR-146b could regulate NIS expression/activity; what is more important, miR-146b interference would contribute to the recovery of radioiodine-sensitivity in dedifferentiated cells via positively regulating NIS. In the present study, it was concluded that NIS-mediated RAIU could be modulated by miR-146b; accordingly, miR-146b might serve as one of targets to enhance efficacy of radioactive therapy against poorly differential thyroid carcinoma (PDTC). - Highlights: • Significant upregulated miR-146b was picked up from thyroid relative miRNAs in DTC. • MiR-146b was negatively regulated by HDAC3 in normal thyroid carcinoma cells. • NIS activity and expression could be regulated by miR-146b in thyroid carcinoma. • MiR-146b inhibition could recover the decreased radioiodine-sensitivity of DTC cells.

    Thyroglossal duct and lingual thyroid ectopic lesions are exceedingly rare synchronous findings. Papillary thyroid carcinoma of these ectopic thyroid sites is well understood but still a rare finding. This case points to some management nuances in regard to ectopic thyroid screening with imaging and also shows the effectiveness of minimally invasive transoral robotic surgery for lingual thyroid.

    Between 1984 and 2002, pulmonary metastases were detected in 42 (4%) out of 1,023 patients with differentiated thyroid carcinoma (DTC) in our department. The age at diagnosis ranged from 6 to 77 years. Lung metastases were diagnosed by both increased thyroglobulin (Tg) levels and positive uptake of iodine-131 on scans, and/or positive radiological findings. The primary tumours were histologically classified as papillary (30 patients), follicular (nine patients) and poorly differentiated (two tall cell, one insular carcinoma). The duration of follow-up ranged from 24 to 228 months. The end-results of the (131)I therapy were evaluated. The treatment of choice was (131)I therapy of metastases after total thyroidectomy plus lymph node dissection (if lymph node metastases were present). Applied single and total (131)I activities were 1.8-10.4 GBq and 5.5-43.7 GBq, respectively. Lung metastases were present at the time of diagnosis in 30 patients and developed during the follow-up period in the remaining 12. Twelve patients with extensive metastases died of thyroid carcinoma and another died due to secondary malignancy (malignant mesothelioma). Ten patients with lung metastases remain completely free of disease and are probably cured, while another seven were stable at the time of study. Three- and five-year survival rates were 86% (36/42) and 76% (32/42), respectively. To define the diagnostic value of high-resolution computed tomography (HRCT) and identify the distinctive features of lung metastases from DTC, 22 patients were further examined with HRCT within 2 weeks of the initial diagnosis of lung metastases and the results were compared with chest X-ray findings. HRCT detected metastases in 10 out of 14 patients with a normal chest X-ray and confirmed metastases in all patients with positive (n=5) and suspicious (n=3) chest X-ray. HRCT did not show any abnormalities in four patients with positive lung uptake on (131)I whole-body images. Stage of disease, existence

    The thyrocytes are exposed to high levels of oxidative stress which could induce DNA damages. Base excision repair (BER) is one of the principal mechanisms of defense against oxidative DNA damage, however recent evidences suggest that also nucleotide excision repair (NER) could be involved. The aim of present work was to identify novel differentiated thyroid cancer (DTC) risk variants in BER and NER genes. For this purpose, the most strongly associated SNPs within NER and BER genes found in our previous GWAS on DTC were selected and replicated in an independent series of samples for a new case-control study. Although a positive signal was detected at the nominal level of 0.05 for rs7689099 (encoding for an aminoacid change proline to arginine at codon 117 within NEIL3), none of the considered SNPs (i.e. rs7990340 and rs690860 within RFC3, rs3744767 and rs1131636 within RPA1, rs16962916 and rs3136166 in ERCC4, and rs17739370 and rs7689099 in NEIL3) was associated with the risk of DTC when the correction of multiple testing was applied. In conclusion, a role of NER and BER pathways was evoked in the susceptibility to DTC. However, this seemed to be limited to few polymorphic genes and the overall effect size appeared weak.

    Tyrosine kinase inhibitors (TKI) have shown clinical effectiveness in iodine-refractory differentiated thyroid cancer (DTC). The corresponding role of serum thyroglobulin (Tg) in iodine-refractory DTC has not been investigated yet. 9 patients (3 female, 61 ± 8y) with progressive iodine-refractory DTC starting on lenvatinib were considered. Tumor restaging was performed every 2-3 months including contrast-enhanced computed tomography (CT, RECIST 1.1). Serum Tg was measured and compared to imaging findings. After treatment initiation, serum Tg levels dropped in all patients with a median reduction of 86.2%. During long-term follow-up (median, 25.2 months), fluctuations in Tg could be observed in 8/9 subjects. According to RECIST, 6/9 subjects achieved a partial response or stable disease with the remaining 3/9 experiencing progressive disease (2/3 with Tg levels rising above baseline). All of the patients with disease progression presented with a preceding continuous rise in serum Tg, whereas tumor marker oscillations in the subjects with controlled disease were only intermittent. Initiation of lenvatinib in iodine-refractory DTC patients is associated with a significant reduction in serum Tg levels as a marker of treatment response. In the course of treatment, transient Tg oscillations are a frequent phenomenon that may not necessarily reflect morphologic tumor progression. PMID:27306607

    Well-differentiated thyroid cancers (WDTCs) are generally indolent cancers that are associated with a low mortality. Although the incidence of these tumors is increasing, there has not been an associated increase in the mortality rates. As we gain a greater understanding and more experience with these good prognosis cancers, the way in which we treat these tumors is evolving. The definition of persistent or recurrent disease has seen a shift from being a clinical and/or radiological diagnosis to now one based on a biochemical blood marker, thyroglobulin. Central lymph node metastases are a very common problem in WDTC, being present in up to 90% of patients. The optimal surgical management of the central lymph node compartment remains a hotly debated topic. This paper identifies these controversies and presents available data surrounding these issues. Biochemical tumor markers are gaining wider use in practice and in time hopefully provide more specific information with which surgical decision-making can be based. A summary of the clinically available markers is presented. PMID:21969828

    Over the past decades, the incidence of differentiated thyroid carcinoma (DTC) has steadily increased, with especially a growing number of low-risk patients. Whereas DTC used to be treated rather aggressively, it is now acknowledged that aggressive treatment does not affect outcome for low-risk patients and that it can induce adverse effects. In this review an overview of the most clinically relevant adverse effects of radioiodine treatment and thyroid hormone suppression therapy (THST) is presented, and the trend toward less aggressive treatment for low-risk patients is outlined. Salivary gland dysfunction occurs in roughly 30% of patients, and is probably due to the concentration of radioiodine in the salivary glands by the sodium/iodide symporter. Beta radiation from radioiodine can result in sialoadenitis and eventually fibrosis and loss of salivary function. Furthermore, patients can experience bone marrow dysfunction following radioiodine treatment. Although this is in general subclinical and transient, patients that receive very high cumulative radioiodine doses may be at risk for more severe bone marrow dysfunction. THST can induce adverse cardiovascular effects in patients with DTC, such as diastolic and systolic dysfunction, and also adverse vascular and prothrombotic effects have been described. Finally, the effects of THST on bone formation and resorption are outlined; especially postmenopausal women with DTC on THST seem to be at risk of bone loss. In the past years, advances have been made in preventing low-risk patients from being overtreated. Improved biomarkers are still needed to further optimize risk stratification and personalize medicine. PMID:26279993

    Hypercalcitoninemia has frequently been reported as a marker for medullary thyroid carcinoma. Currently, calcitonin measurements are mostly useful in the evaluation of tumor size and progression, and as an index of biochemical improvement of medullary thyroid carcinomas. Although measurement of calcitonin is a highly sensitive method for the detection of medullary thyroid carcinoma, it presents a low specificity for this tumor. Several physiologic and pathologic conditions other than medullary thyroid carcinoma have been associated with increased levels of calcitonin. Several cases of thyroid nodules associated with increased values of calcitonin are not medullary thyroid carcinomas, but rather are related to other conditions, such as hypercalcemias, hypergastrinemias, neuroendocrine tumors, renal insufficiency, papillary and follicular thyroid carcinomas, and goiter. Furthermore, prolonged treatment with omeprazole (> 2–4 months), beta-blockers, glucocorticoids and potential secretagogues, have been associated with hypercalcitoninemia. An association between calcitonin levels and chronic auto-immune thyroiditis remains controversial. Patients with calcitonin levels >100 pg/mL have a high risk for medullary thyroid carcinoma (~90%–100%), whereas patients with values from 10 to 100 pg/mL (normal values: <8.5 pg/mL for men, < 5.0 pg/mL for women; immunochemiluminometric assay) have a <25% risk for medullary thyroid carcinoma. In multiple endocrine neoplasia type 2 (MEN2), RET mutation analysis is the gold-standard for the recommendation of total preventive thyroidectomy to relatives at risk of harboring a germline RET mutation (50%). False-positive calcitonin results within MEN2 families have led to incorrect indications of preventive total thyroidectomy to RET mutation negative relatives. In this review, we focus on the differential diagnosis of hypercalcitoninemia, underlining its importance for the avoidance of misdiagnosis of medullary thyroid carcinoma and

    Purpose. To systematically review clinical studies examining the effectiveness of nonpharmacological methods to prevent/minimize salivary gland damage due to radioiodine treatment of differentiated thyroid carcinoma (DTC). Methods. Reports on relevant trials were identified by searching the PubMed, CINHAL, Cochrane, and Scopus electronic databases covering the period 01/2000-10/2015. Inclusion/exclusion criteria were prespecified. Search yielded eight studies that were reviewed by four of the present authors. Results. Nonpharmacological methods used in trials may reduce salivary gland damage induced by radioiodine. Sialogogues such as lemon candy, vitamin E, lemon juice, and lemon slice reduced such damage significantly (p < 0.0001, p < 0.05, p < 0.10, and p < 0.05, resp.). Parotid gland massage also reduced the salivary damage significantly (p < 0.001). Additionally, vitamin C had some limited effect (p = 0.37), whereas no effect was present in the case of chewing gum (p = 0.99). Conclusion. The review showed that, among nonpharmacological interventions, sialogogues and parotid gland massage had the greatest impact on reducing salivary damage induced by radioiodine therapy of DTC. However, the studies retrieved were limited in number, sample size, strength of evidence, and generalizability. More randomized controlled trials of these methods with multicenter scope and larger sample sizes will provide more systematic and reliable results allowing more definitive conclusions.

    Lung metastases were demonstrated by total-body /sup 131/I scans in 23 patients with differentiated thyroid carcinoma, at a time when chest x-ray was normal. This total-body /sup 131/I scan was performed after the administration of 2 mCi (in 11 patients) or 100 mCi (in 12 patients). Overall uptake of 131I in lungs was less than 1% of the administered dose in 11 patients. All patients were treated with radioiodine. No lung uptake was found in 20 patients at the last 100 mCi post-therapy scan. Among them, Tg level became undetectable during T4 treatment in eight, lung CT scan showed the disappearance of the micronodules in seven, and lung biopsy did not show evidence of disease in two patients. No patient developed radiation lung fibrosis. In conclusion, favorable responses to radioiodine treatment were observed despite relatively low overall uptake, in relation to the small size of lung metastases. This provides high concentrations of radioiodine and therefore high radiation doses.

    Radiation safety is an integral part of targeted radionuclide therapy. The aim of this work was to study the external dose rate and retained body activity as functions of time in differentiated thyroid carcinoma patients receiving 131I therapy. Seventy patients were stratified into two groups: the ablation group (A) and the follow-up group (FU). The patients’ external dose rate was measured, and simultaneously, their retained body radiation activity was monitored at various time points. The equations of the external dose rate and the retained body activity, described as a function of hours post administration, were fitted. Additionally, the release time for patients was calculated. The reduction in activity in the group receiving a second or subsequent treatment was more rapid than the group receiving only the initial treatment. Most important, an expeditious method was established to indirectly evaluate the retained body activity of patients by measuring the external dose rate with a portable radiation survey meter. By this method, the calculated external dose rate limits are 19.2, 8.85, 5.08 and 2.32 μSv·h−1 at 1, 1.5, 2 and 3 m, respectively, according to a patient’s released threshold level of retained body activity <400 MBq. This study is beneficial for radiation safety decision-making. PMID:25337944

    Incidence rates of differentiated thyroid carcinoma (TC) have increased in many countries. Adiposity and dietary risk factors may play a role, but little is known on the influence of energy intake and macronutrient composition. The aim of this study was to investigate the associations between TC and the intake of energy, macronutrients, glycemic index (GI) and glycemic load in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The study included 477,274 middle-age participants (70.2% women) from ten European countries. Dietary data were collected using country-specific validated dietary questionnaires. Total carbohydrates, proteins, fats, saturated, monounsaturated and polyunsaturated fats (PUFA), starch, sugar, and fiber were computed as g/1,000 kcal. Multivariable Cox regression was used to calculate multivariable adjusted hazard ratios (HR) and 95% confidence interval (CI) by intake quartile (Q). After a mean follow-up time of 11 years, differentiated TC was diagnosed in 556 participants (90% women). Overall, we found significant associations only with total energy (HRQ4 vs .Q1 , 1.29; 95% CI, 1.00-1.68) and PUFA intakes (HRQ4 vs .Q1 , 0.74; 95% CI, 0.57-0.95). However, the associations with starch and sugar intake and GI were significantly heterogeneous across body mass index (BMI) groups, i.e., positive associations with starch and GI were found in participants with a BMI ≥ 25 and with sugar intake in those with BMI < 25. Moreover, inverse associations with starch and GI were observed in subjects with BMI < 25. In conclusion, our results suggest that high total energy and low PUFA intakes may increase the risk of differentiated TC. Positive associations with starch intake and GI in participants with BMI ≥ 25 suggest that those persons may have a greater insulin response to high starch intake and GI than lean people.

    The adrenal metastasis from differentiated thyroid carcinoma is uncommon. Metastatic involvement of both adrenal and brain in the same patient from differentiated thyroid carcinoma is rare. Here, we described an unusual case with iodine-avid lung, bone, adrenal, liver, and brain metastases from follicular thyroid carcinoma confirmed by 131I SPECT/CT. The utilization of SPECT/CT in thyroid cancer patients can detect the presence of metastases and also exclude potential false-positive lesions. Our case demonstrates that SPECT/CT is helpful in localizing and confirming metastatic lesions from differentiated thyroid carcinoma in rare and unusual sites. PMID:26018699

    Thyroid cancer incidence has significantly increased in the last three decades and many patients seek medical attention for its treatment every year. Among follicular cell-derived tumors, the majority are differentiated thyroid carcinomas (DTC), whose prognosis is very good with only 15% of the cases presenting disease persistence or recurrence after initial treatment. Medullary thyroid carcinoma has a worse prognosis, especially in patients with diffused cancers at the time of initial surgery. Traditional treatment options for persistent or recurrent disease include additional surgery, radioiodine treatment and TSH-suppression in DTC patients; external beam radiotherapy, and cytotoxic chemotherapy, often have low efficacy and many patients with advanced disease ultimately die. In the last two decades many of the molecular events involved in cancer formation have been uncovered. This knowledge has prompted the development of novel therapeutic strategies mainly based on the inhibition of key molecular mediators of the tumorigenic process. In particular the class of small-molecule tyrosine kinase inhibitors was enriched by many compounds that have reached clinical trials and in some cases have had approval for clinical use in specific cancers. Many of these compounds entered clinical trials also for locally advanced or metastatic thyroid carcinomas showing very promising results. PMID:20126863

    Thyroid nodules are a frequent finding but engender concern primarily because of a large size or, occasionally, as a manifestation of a carcinoma. Needle biopsy permits a definite diagnosis in the majority of cases. Well-differentiated thyroid carcinoma is treated by surgery, the extent of which would be based on the gross evidence of the extent of the disease, the histologic features of the lesion, the patient's age and overall medical status, and the need to avoid postoperative complications. The appropriate care after surgery is also based on the individual patient. Medullary thyroid carcinoma is best treated by total thyroidectomy with cervical lymph node dissection on the side of a palpable nodule. Serum calcitonin determinations provide diagnostic and some prognostic data. Anaplastic carcinoma is usually best treated by radiation therapy. The outlook is good for most thyroid carcinoma recognized reasonably early.

    Background Predictive role of undetectable thyroglobulin (Tg) in patients with poorly differentiated thyroid carcinoma (PDTC) is unclear. Our goal was to report on Tg levels following total thyroidectomy and adjuvant RAI in PDTC patients and to correlate Tg levels with recurrence. Methods Forty patients with PDTC with no distant metastases at presentation (M0) and managed by total thyroidectomy and adjuvant RAI were identified from a database of 91 PDTC patients. Of these, 31 patients had Tg values recorded and formed the basis of our analysis. A nonstimulated Tg level <1 ng/ml was used as a cutoff point for undetectable Tg levels. Association of patient and tumor characteristics with Tg levels was examined by χ2 test. Recurrence-free survival (RFS) stratified by postop Tg level was calculated by Kaplan–Meier method and compared by log-rank test. Results Twenty patients had undetectable Tg (<1 ng/ml) and 11 had detectable Tg (≥1 ng/ml; range 2–129 ng/ml) following surgery. After adjuvant RAI, 24 patients had undetectable Tg (<1 ng/ml) and 7 had detectable Tg (≥1 ng/ml; range 1–57 ng/ml). Patients with undetectable Tg were less likely to have pathologically positive margins compared to those with detectable Tg (33 vs. 72 % respectively; p = 0.03). Patients with undetectable Tg levels had better 5-year regional control and distant control than patients with detectable Tg level (5-year regional recurrence- free survival 96 vs. 69 %; p = 0.03; 5-year distant recurrence-free survival 96 vs. 46 %, p = 0.11). Conclusion Postoperative thyroglobulin levels in subset of patients with PDTC appear to have predictive value for recurrence. Patients with undetectable Tg have a low rate of recurrence.

    Sorafenib (Nexavar®) is the first tyrosine kinase inhibitor to be approved for the treatment of radioactive iodine (RAI)-refractory differentiated thyroid carcinoma (DTC). In the pivotal phase III DECISION trial in patients with RAI-refractory, locally advanced or metastatic DTC, oral sorafenib 400 mg twice daily significantly prolonged median progression-free survival (PFS) relative to placebo. The PFS benefit of sorafenib over placebo was evident in all pre-specified clinical and genetic biomarker subgroups, and neither BRAF nor RAS mutation status was predictive of sorafenib benefit for PFS. The objective response rate was significantly higher in patients receiving sorafenib than in those receiving placebo; all objective responses were partial responses. The overall survival benefit of sorafenib is as yet unclear, with no significant benefit observed at the time of primary analysis or at 9 months following the primary analysis. Overall survival was possibly confounded by the crossover of patients in the placebo group to sorafenib upon disease progression. The adverse events associated with sorafenib in the DECISION trial were consistent with the known tolerability profile of the drug, with hand-foot skin reaction, diarrhea, and alopecia reported most commonly. Most treatment-emergent adverse events were grade 1 or 2 in severity and occurred early in treatment. However, a high proportion of patients discontinued sorafenib therapy or required dose reductions or interruptions because of toxicity. Although final overall survival data are awaited, current evidence suggests that sorafenib is a promising new treatment option for patients with RAI-refractory, metastatic DTC. PMID:25742918

    To date a few studies have focused on the possible effects of subclinical hyperthyroidism on bone metabolism, showing conflicting results. This study was designed to evaluate this possibility. Sixty-six patients, 22 pre-menopausal women, 33 post-menopausal women and 11 men, who had received iodine-131 ((131)I) ablation postoperatively for well differentiated thyroid carcinoma (WDTC) and were treated for a long term with levothyroxine (T(4)), entered the study and were compared with sixty-six healthy controls individually matched to the patients for age, gender and menopausal status. The bone mineral density (BMD) of lumbar and hip regions of the patients was measured, while on the T(4) suppressive treatment, with average duration of 14.93+/-2.17 months after initiation of the T(4) suppressive treatment and was compared with the BMD of healthy controls. All patients were in the subclinical hyperthyroid state, while all controls were serologically and clinically euthyroid. Our results show that there was no significant difference in BMD measured at the lumbar spine of patients and controls in any subgroup (P>0.05). Analysis of the data of BMD from the hips in men, premenopausal women and controls, also revealed no difference. It was noted that the mean BMD of the femur in the postmenopausal women were at the statistical limit of significance as compared to the control group (P=0.05). In conclusion, our findings indicate that the replacement dose of T(4) in WDTC patients after (131)I ablation, does not have a significant effect on BMD in men, in pre and post-menopausal women and hence on the risk of osteoporosis. In post-menopausal women, the mean femoral BMD was at the limit of statistical significance. PMID:19081859

    Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. Here, we describe the genomic landscape of 496 PTCs. We observed a low frequency of somatic alterations (relative to other carcinomas) and extended the set of known PTC driver alterations to include EIF1AX, PPM1D, and CHEK2 and diverse gene fusions. These discoveries reduced the fraction of PTC cases with unknown oncogenic driver from 25% to 3.5%. Combined analyses of genomic variants, gene expression, and methylation demonstrated that different driver groups lead to different pathologies with distinct signaling and differentiation characteristics. Similarly, we identified distinct molecular subgroups of BRAF-mutant tumors, and multidimensional analyses highlighted a potential involvement of oncomiRs in less-differentiated subgroups. Our results propose a reclassification of thyroid cancers into molecular subtypes that better reflect their underlying signaling and differentiation properties, which has the potential to improve their pathological classification and better inform the management of the disease.

    Untreated hyperthyroidism and high-dose thyroid hormone are associated with osteoporosis, and increased bone mineral density (BMD) has been demonstrated in postmenopausal females with hypoparathyroidism. Studies on the effect of suppressive levothyroxine (LT4) therapy on BMD and bone metabolism after total thyroidectomy in patients with differentiated thyroid carcinoma have presented conflicting results, and few studies in relation to the status of hypoparathyroidism have been studied. One hundred postmenopausal women and 24 premenopausal women on LT4 suppression therapy were included in this study. BMD of lumbar spine and femur and bone turnover markers were measured at the baseline and during the follow-up period up to 18 months using dual energy X-ray absorptiometry. Biochemical marker of bone resorption was measured by urine deoxypyridinoline and bone formation by serum osteocalcin. The age ranged from 36 to 64 years old. Thyroid stimulating hormone (TSH) was suppressed during the study. The results showed that BMD of femur and lumbar spine were not significantly changed in both pre- and postmenopausal women except femur neck in postmenopausal women without hypoparathyroidism. Patients with hypoparathyroidism had higher BMD gain than those without hypoparathyroidism in total hip (1.25 vs. -1.18%, P=0.015). Biochemical markers of bone turnover, serum osteocalcin, and urine deoxypyridinoline did not show significant change. In conclusion, patients with well differentiated thyroid carcinoma are not at a great risk of bone loss after LT4 suppressive therapy. The state of hypoparathyroidism is associated with increased BMD, particularly in postmenopausal women. PMID:26389089

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

    The presence of hyperthyroidism is no longer an insurance against the occurrence of thyroid cancer. The combination of the two is common. This is a retrospective study of 355 files of patients followed for differentiated thyroid cancer in the endocrinology department at CHU IBN ROCHD from 1986 to 2014. 12 of those patients were followed for hyperthyroidism, and a fortuitous association with differentiated thyroid cancer was found during the anatomopathological exam, giving us a 3.38% prevalence. The average age of discovery is 44.8 years, with a marked female predominance (8/12). Eight patients had a toxic nodule, 3 had Basedow's goiters, and one had Graves' disease. All underwent total thyroidectomy. In all patients, the cancer was a papillary carcinoma. Microcarcinoma was the most predominant (6 patients). An insular carcinoma was found in a patient with spinal and retro-orbital metastases. Treatment with radioactive iodine was prescribed to five patients. The diagnosis of hyperthyroidism does not eliminate the possibility of an associated thyroid cancer. Malignancy should always be kept in mind and therefore lead to a diagnostic approach comparable to that for any thyroid nodule. PMID:27583082

    Background There are limited data about whether patients who receive initial treatment for differentiated thyroid cancer (DTC) gain or lose weight during long-term follow-up under thyroid stimulating hormone (TSH) suppression. This study was aimed to evaluate whether DTC patients under TSH suppression experience long-term weight gain after initial treatment. We also examined the impact of the radioactive iodine ablation therapy (RAIT) preparation method on changes of weight, comparing thyroid hormone withdrawal (THW) and recombinant human TSH (rhTSH). Methods We retrospectively reviewed 700 DTC patients who underwent a total thyroidectomy followed by either RAIT and levothyroxine (T4) replacement or T4 replacement alone. The control group included 350 age-matched patients with benign thyroid nodules followed during same period. Anthropometric data were measured at baseline, 1 to 2 years, and 3 to 4 years after thyroidectomy. Comparisons were made between weight and body mass index (BMI) at baseline and follow-up. Results Significant gains in weight and BMI were observed 3 to 4 years after initial treatment for female DTC but not in male patients. These gains among female DTC patients were also significant compared to age-matched control. Women in the THW group gained a significant amount of weight and BMI compared to baseline, while there was no increase in weight or BMI in the rhTSH group. There were no changes in weight and BMI in men according to RAIT preparation methods. Conclusion Female DTC patients showed significant gains in weight and BMI during long-term follow-up after initial treatment. These changes were seen only in patients who underwent THW for RAIT.

    An activated ras oncogene induces a program of differentiation in the human medullary thyroid cancer cell line TT. This differentiation process is accompanied by a marked increase in the transcription of the human calcitonin (CT) gene. We have localized a unique Ras-responsive transcriptional element (RRE) in the CT gene promoter. DNase I protection indicates two domains of protein-DNA interaction, and each domain separately can confer Ras-mediated transcriptional inducibility. This bipartite RRE was also found to be Raf responsive. By affinity screening, we have cloned a cDNA coding for a zinc finger transcription factor (RREB-1) that binds to the distal RRE. The consensus binding site for this factor is CCCCAAACCACCCC. RREB-1 is expressed ubiquitously in human tissues outside the adult brain. Overexpression of RREB-1 protein in TT cells confers the ability to mediate increased transactivation of the CT gene promoter-reporter construct during Ras- or Raf-induced differentiation. These data suggest that RREB-1 may play a role in Ras and Raf signal transduction in medullary thyroid cancer and other cells. PMID:8816445

    Metastatic and recurrent differentiated thyroid carcinoma is preferably treated with 131I, whose administered activity is limited by red marrow (RM) toxicity, originally correlated by Benua to a blood absorbed dose higher than 2 Gy. Afterward a variety of dosimetric approaches has been proposed. The aim of this work is to compare the results of the Benua formula with the ones of other three blood and RM absorbed dose formulae. Materials and methods have been borrowed by the dosimetric protocol of the Italian Internal Dosimetry group and adapted to the routine of our centre. Wilcoxon t-tests and percentage differences have been applied for comparison purposes. Results are significantly different (p < 0.05) from each other, with an average percentage difference between Benua versus other results of -22%. The dosimetric formula applied to determine blood or RM absorbed dose may contribute significantly to increase heterogeneity in absorbed dose and dose-response results. Standardization should be a major objective.

    Epithelial–mesenchymal transition is an important mechanism of epithelial tumor progression, local invasion and metastasis. The E-cadherin (CDH1) repressor SLUG (SNAI2) and the basic helix–loop–helix transcription factor TWIST1 inhibit CDH1 expression in poorly differentiated malignancies as inducers of epithelial– mesenchymal transition. Epithelial–mesenchymal transition has been implicated in progression from well to poorly differentiated/anaplastic thyroid carcinoma but the expression of SNAI2 and TWIST1 proteins and their phenotypic association in human thyroid cancers has not been extensively studied. We examined the expression of SNAI2, TWIST1 and CDH1 by immunohistochemistry in a panel of well-differentiated and anaplastic thyroid cancers and by qRT-PCR in thyroid cell lines. Ten normal thyroids, 33 follicular adenomas, 56 papillary thyroid carcinomas including 28 follicular variants, 27 follicular carcinomas and 10 anaplastic thyroid carcinomas were assembled on a tissue microarray and immunostained for SNAI2, TWIST1 and CDH1. Most (8/10) anaplastic thyroid carcinomas demonstrated strong nuclear immunoreactivity for SNAI2 with associated absence of CDH1 in 6/8 cases (75%). TWIST1 was expressed in 5/10 anaplastic thyroid carcinomas with absence of CDH1 in 3/5 (60%) cases. These findings were confirmed in whole sections of all anaplastic thyroid carcinomas and in a separate validation set of 10 additional anaplastic thyroid carcinomas. All normal thyroids, follicular adenomas, papillary and follicular thyroid carcinomas were negative for SNAI2 and TWIST1 (P<0.0001) and all showed strong diffuse immunoreactivity for CDH1 (P=0.026). Expression of SNAI2, TWIST1 and CDH1 mRNA varied in a normal thyroid, papillary carcinoma and two anaplastic thyroid carcinoma cell lines tested, but the highest levels of CDH1 mRNA were detected in the normal thyroid cell line while the anaplastic thyroid carcinoma cell line demonstrated the highest levels of SNAI2 and

    Background and aim This study aimed at determining whether there is a risk regarding the development of second primary malignancies after patient exposure to the low and medium radioiodine activity used during the treatment of differentiated thyroid cancers (DTC). Methods Second primary malignancies that occurred after DTC were detected in 1,990 patients treated between 1970 and 2003. The mean long-term follow-up period was 182 months. Results Radioiodine I-131was administrated at a mean dose of 63.2 mCi. There were 93 patients with at least one second primary malignancy. The relative risk of development of second malignancy in DTC patients was increased (p<0.0001) for breast, uterine and ovarian cancers compared with the general population. Conclusions The overall risk concerning the development of second primary malignancies was related to the presence of DTC, but not to exposure to the low and medium activities of radioiodine administered as adjuvant therapy.

    Since 1975, the American Cancer Society, Illinois Division, has published end results of major cancer sites drawn from patient data contributed voluntarily by hospital cancer registries throughout the state. The current study was undertaken, in part, to apprehend information regarding contested areas in the management of patients having differentiated (papillary/follicular) thyroid cancer. A total of 2,282 patients with either papillary or follicular carcinoma of the thyroid from 76 different Illinois hospitals and providing 10 years of follow-up information (life-table analysis) were retrospectively analyzed for demographic, disease, and treatment-related predictors of survival. Multivariate analysis using the Cox proportional hazards method was made for stage, age, race, sex, morphology, history of radiation exposure, presence of positive lymph nodes, initial surgical treatment, postoperative iodine 131 therapy, and replacement/suppressive thyroid hormone treatment. Statistically significant (p less than or equal to 0.05) predictors of favorable survival after thyroid cancer were low stage (I and II), young age (less than 50 years), white race, female sex, and the administration, postoperatively, of either thyroid hormone or radioactive iodine. Factors that had no influence on survival were lymph node status, choice of initial surgical treatment, and a history of prior irradiation. We suggest that where a prospective clinical trial is impracticable, a retrospective analysis of a large and detailed database, such as that available from cooperating hospital-based tumor registries, may yet provide useful insights to solutions of cancer management problems.

    A study directed to the cytogenetic and dosimetric aspects of radionuclides of medical interest is very valuable, both for an accurate evaluation of the dose received by the patients, and consequently of the genetic damage, and for the optimization of therapeutic strategies. Cytogenetic and dosimetric effects of (131)I in lymphocytes of thyroidectomized differentiated thyroid cancer (DTC) patients were evaluated through chromosome aberration (CA) technique: Euthyroid patients submitted to recombinant human thyroid-stimulating hormone (rhTSH) therapy (group A) were compared with hypothyroid patients left without levothyroxine treatment (group B). CA analysis was carried out prior to and 24 h, 1 week, 1 month and 1 year after radioiodine administration (4995-7030 MBq) in both groups. An activity-response curve of (131)I (0.074-0.740 MBq/mL) was elaborated, comparing dicentric chromosomes in vivo and in vitro in order to estimate the absorbed dose through Monte Carlo simulations. In general, radioiodine therapy induced a higher total CA rate in hypothyroid patients as compared to euthyroid patients. The frequencies of dicentrics obtained in DTC patients 24 h after treatment were equivalent to those induced in vitro (0.2903 ± 0.1005 MBq/mL in group A and 0.2391 ± 0.1019 MBq/mL in group B), corresponding to absorbed doses of 0.65 ± 0.23 Gy and 0.53 ± 0.23 Gy, respectively. The effect on lymphocytes of internal radiation induced by (131)I therapy is minimal when based on the frequencies of CA 1 year after the treatment, maintaining a higher quality of life for DTC patients receiving rhTSH-aided therapy.

    Tyrosine kinase inhibitors (TKI) have shown clinical effectiveness in iodine-refractory differentiated thyroid cancer (DTC). The corresponding role of serum thyroglobulin (Tg) in iodine-refractory DTC has not been investigated yet. 9 patients (3 female, 61 ± 8y) with progressive iodine-refractory DTC starting on lenvatinib were considered. Tumor restaging was performed every 2–3 months including contrast-enhanced computed tomography (CT, RECIST 1.1). Serum Tg was measured and compared to imaging findings. After treatment initiation, serum Tg levels dropped in all patients with a median reduction of 86.2%. During long-term follow-up (median, 25.2 months), fluctuations in Tg could be observed in 8/9 subjects. According to RECIST, 6/9 subjects achieved a partial response or stable disease with the remaining 3/9 experiencing progressive disease (2/3 with Tg levels rising above baseline). All of the patients with disease progression presented with a preceding continuous rise in serum Tg, whereas tumor marker oscillations in the subjects with controlled disease were only intermittent. Initiation of lenvatinib in iodine-refractory DTC patients is associated with a significant reduction in serum Tg levels as a marker of treatment response. In the course of treatment, transient Tg oscillations are a frequent phenomenon that may not necessarily reflect morphologic tumor progression. PMID:27306607

    Background Cardiac metastases from papillary thyroid carcinoma are very uncommon. Their incidence is rising due to improvements in survival and diagnosis; nevertheless, our patient is the fourth case reported up to date. There are no clinical trials available in this scenario. Therefore, treatment choice is made based on clinical experience and case reports; notably, the largest case report series was prior to the approval for using tyrosine-kinase inhibitors in thyroid cancer. Patient A 73-year-old lady had dedifferentiated papillary thyroid cancer with ongoing sorafenib. After 9 months on this treatment, she presented with dyspnea and heart failure. Differential diagnosis included infection, progression of disease and cardiotoxicity. After a comprehensive assessment (echocardiography, computed tomography, PET, magnetic resonance), we found progression of lung disease, and the appearance of heart metastases. Results After recovering from the basal status, she started on second-line treatment with sunitinib, which was well-tolerated. She achieved stable disease with a decrease in tumor marker levels. Conclusions We should include cardiac metastases in the differential diagnosis of heart failure in cancer patients. Magnetic resonance imaging is the gold standard for assessment. Sorafenib is the mainstay of the first-line therapy in metastatic thyroid cancer, achieving long-term disease control with good tolerance. Sunitinib could be a safe second-line treatment option (not cardiotoxicity related) with promising results. Therefore, our report presents a sequence of treatment with tyrosine-kinase inhibitors in metastatic thyroid carcinoma with an encouraging outcome, which deserves further investigation.

    Summary Resistance to thyroid hormone (RTH) is a syndrome of reduced tissue responsiveness to thyroid hormones. RTH is majorly caused by mutations in the thyroid hormone receptor beta (THRB) gene. Recent studies indicated a close association of THRB mutations with human cancers, but the role of THRB mutation in carcinogenesis is still unclear. Here, we report a rare case of RTH with a papillary thyroid carcinoma (PTC). A 26-year-old woman was referred to our hospital due to a thyroid tumor and hormonal abnormality. She had elevated serum thyroid hormones and non-suppressed TSH levels. Genetic analysis of THRB identified a missense mutation, P452L, leading to a diagnosis of RTH. Ultrasound-guided fine-needle aspiration biopsy of the tumor and lymph nodes enabled the cytological diagnosis of PTC with lymph node metastases. Total thyroidectomy and neck lymph nodes dissection were performed. Following surgery, thyroxine replacement (≥500 μg) was necessary to avoid the symptoms of hypothyroidism and to maintain her TSH levels within the same range as before the operation. During the follow-up, basal thyroglobulin (Tg) levels were around 6 ng/ml and TSH-stimulated Tg levels were between 12 and 20 ng/ml. Up to present, the patient has had no recurrence of PTC. This indicates that these Tg values are consistent with a biochemical incomplete response or an indeterminate response. There is no consensus regarding the management of thyroid carcinoma in patients with RTH, but aggressive treatments such as total thyroidectomy followed by radioiodine (RAI) and TSH suppression therapy are recommended. Learning points There are only a few cases reporting the coexistence of RTH and thyroid carcinoma. Moreover, our case would be the first case presenting one with lymph node metastases. Recent studies indicated a close association of THRB mutations with human cancers, but the role of THRB mutation in carcinogenesis is still unclear. When total thyroidectomy is performed in

    Objective. Currently, total thyroidectomy (TT) is widely used to treat benign thyroid diseases and thyroid carcinoma. The differential diagnosis between benign and malignant thyroid disorders and the potential identification of thyroid microcarcinomas with biochemical markers remain controversial. This retrospective study aimed to estimate the prognostic validity of thyroid autoantibodies, thyroglobulin (Tg), and the thyroid disease type in diagnostic approaches regarding the co-existence of incidental thyroid carcinoma (ITC) with benign thyroid diseases. Methods. A cohort of 228 patients was treated with TT for benign thyroid disorders between 2005 and 2010. Thyroid autoantibodies and Tg were preoperatively estimated. Patients were classified according to the preoperative and histologically established diagnoses, and the median values of the biochemical markers were compared between the groups. Results. ITC was detected in 33/228 patients and almost exclusively in the presence of nontoxic thyroid disorders (P = 0.014). There were no statistically significant differences in the median values of the biochemical markers between the benign and malignant groups. There was also no significant association between ITC and chronic lymphocytic thyroiditis. Conclusions. The co-existence of ITC with benign and especially nontoxic thyroid diseases is significant, and treatment of these disorders with TT when indicated can lead to the identification and definitive cure of microcarcinomas. Further studies are required to establish precise markers with prognostic validity for TC diagnosis. PMID:24348554

    Twelve patients with coexistent well-differentiated thyroid carcinoma and primary hyperparathyoidism were studied to determine the frequency of previous radiation exposure. Eight were found to have received prior irradiation. External radiation was administered to the head and neck region for benign conditions such as tonsillar enlargement, acne, scrofula, and thyroid enlargement. One patient received 131I therapy for carcinoma of the thyroid. The observation that 67% of the patients in this series had previous radiation to the head and neck strongly implicates radiation exposure in the development of coexistent well-differentiated thyroid carcinoma and hyperparathyroidism.

    Insular carcinoma, once considered a poorly-differentiated thyroid cancer, has been reclassified as a distinct thyroid neoplasm. Since this neoplasm is composed of follicular epithelial cells, it may concentrate radioiodide (131I) making postoperative 131I imaging for detection of metastases and radiotherapy possible. A 20-yr review of 35 cases diagnosed as anaplastic or undifferentiated thyroid carcinoma at this medical center revealed five patients with insular carcinoma. Four patients showed postoperative 131I localization and received therapeutic doses of 131I. Three of the four showed extrathyroidal 131I localization in neoplastic lesions. In one patient, the resolution of metastatic lesions by magnetic resonance and 131I imaging suggests that 131I may have an important therapeutic role in this aggressive neoplasm.

    Lymph node metastasis of nasopharyngeal carcinoma follows an orderly pattern, and diagnosis of nasopharyngeal carcinoma is often made by lymph node biopsy. In the present study, following neck palpation, ultrasonography and cervical computer tomography, a 52-year-old female patient with thyroid adenoma and enlarged cervical lymph nodes was misdiagnosed as thyroid carcinoma without undergoing preoperative biopsy, followed by unnecessary total thyroidectomy. Systematic CT scan and nasal endoscopic biopsy confirmed the correct diagnosis of primary NPC concurrent with thyroid adenoma. The patient received palliative radiotherapy and L-thyroxine substitution therapy, and was followed up closely via internet-based approaches with life-style intervention, medication consultation and psychological support for improvement of life quality after radiotherapy. In conclusion, primary malignancies with thyroid metastasis must be considered in the differential diagnosis of thyroid tumors with enlarged cervical lymph nodes. PMID:27347179

    Abstract This article investigates the association of the time interval between the diagnostic dose and ablation with the stunning effect, when a 74 MBq 131I pretherapy scanning was performed on patients with differentiated thyroid carcinoma (DTC); the patients who were diagnosed as DTC and would be performed radioiodine (RAI) ablation of thyroid remnants or metastases were recruited during January 2011 and May 2012 in our hospital. Thirty-seven patients with DTC who had the RAI ablation of thyroid remnants or metastases for the first time were recruited. All the patients received a dose of 1850 to 7400 MBq of 131I for ablation and a diagnostic scan was performed 24 hours after the administration of 74 MBq 131I before ablation. A posttherapy scan was performed 2 to 7 days after the ablation. The patients were broken down into 3 groups (G1, G2, and G3) according to the interval time between the diagnostic dose and therapy (1–3, 4–7, and >7 days). The fractional concentrations of 131I in remnants or functional metastases were quantified and expressed as therapeutic/diagnostic (Rx/Dx). The level of significance was set at 0.05. Sixty-seven foci were found both on pretherapy and posttherapy scans, the mean ratio of Rx/Dx was 0.43 ± 0.29, and the ratio of 49 foci (73.13%) was <0.6. The ratios in G1, G2, and G3 were 0.46 ± 0.29, 0.29 ± 0.18, and 0.55 ± 0.33, respectively. The differences between G1 and G2, and G2 and G3 were statistically significant (t = 2.40, P = 0.021 and t = 3.28, P = 0.002), whereas the difference between G1 and G3 was not significant (t = 1.01, P = 0.319). By a diagnostic scan of 74 MBq 131I, stunning prominently occurs with a time of 4 to 7 days between the diagnostic dose and ablation. We recommend that for less stunning effect, RAI ablation should be performed within 3 days or postponed until 1 week after the diagnostic dose administrated. PMID:26252311

    Intratumoural hypoxia (low oxygen tension) is associated with aggressive disease and poor prognosis. Hypoxia-inducible factor-1 is a transcription factor activated by hypoxia that regulates the expression of genes that promote tumour cell survival, progression, metastasis, and resistance to chemo/radiotherapy. In addition to hypoxia, HIF-1 can be activated by growth factor-signalling pathways such as the mitogen-activated protein kinases- (MAPK-) and phosphatidylinositol-3-OH kinases- (PI3K-) signalling cascades. Mutations in these pathways are common in thyroid carcinoma and lead to enhanced HIF-1 expression and activity. Here, we summarise current data that highlights the potential role of both hypoxia and MAPK/PI3K-induced HIF-1 signalling in thyroid carcinoma progression, metastatic characteristics, and the potential role of HIF-1 in thyroid carcinoma response to radiotherapy. Direct or indirect targeting of HIF-1 using an MAPK or PI3K inhibitor in combination with radiotherapy may be a new potential therapeutic target to improve the therapeutic response of thyroid carcinoma to radiotherapy and reduce metastatic burden.

    Primary thyroid paraganglioma (TP) is an uncommon tumor, and in rare cases, this disease tends to mimic medullary thyroid carcinoma (MTC). The present study reports a rare case of primary TP mimicking thyroid carcinoma, accompanied by hyperthyroidism. A 30-year-old female presented with an anterior cervical mass. Pre-operative radiological studies and operative frozen section analysis indicated an atypical MTC. Primary TP was finally diagnosed by pathology and immunohistochemical staining. Laboratory examinations (thyroid hormones tests) and Tc99m emission computed tomography revealed hyperthyroidism. Gene analysis of TP-associated gene mutations was negative. Surgical resection was performed as a curative approach and there is currently no metastasis after 36 months of follow-up. Surgeons must be aware of this disease in order to ensure a correct diagnosis and to prevent them from performing unnecessary procedures. The current study presents a case of primary TP mimicking MTC, discusses the radiographic results and histological characteristics, and provides a review of the associated literature. PMID:26622613

    Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy. We performed shotgun liquid chromatography (LC)/tandem mass spectrometry (MS/MS) analysis on pooled protein extracts from patients with PTC and compared the results with those from normal thyroid tissue validated by real-time (RT) PCR and immunohistochemistry (IHC). We detected 524 types of protein in PTC and 432 in normal thyroid gland. Among these proteins, 145 were specific to PTC and 53 were specific to normal thyroid gland. We have also identified two important new markers, nephronectin (NPNT) and malectin (MLEC). Reproducibility was confirmed with several known markers, but the one of two new candidate markers such as MLEC did not show large variations in expression levels. Furthermore, IHC confirmed the overexpression of both those markers in PTCs compared with normal surrounding tissues. Our protein data suggest that NPNT and MLEC could be a characteristic marker for PTC. PMID:22518348

    Even though it is a rare event, most associations of thyroid carcinoma with subacute thyroiditis described in the literature are related to its granulomatous form (Quervain's thyroiditis). We present a patient with subacute lymphocytic thyroiditis (painless thyroiditis) and papillary thyroid cancer that was first suspected in an initial ultrasound evaluation. A 30-year old female patient who was referred to the emergency room due to hyperthyroidism symptoms was diagnosed with painless thyroiditis established by physical examination and laboratory findings. With the presence of a palpable painless thyroid nodule an ultrasound was prescribed and the images revealed a suspicious thyroid nodule, microcalcification focus in the heterogeneous thyroid parenquima and cervical lymphadenopathy. Fine needle aspiration biopsy was taken from this nodule; cytology was assessed for compatibility with papillary thyroid carcinoma. Postsurgical pathology evaluation showed a multicentric papillary carcinoma and lymphocytic infiltration. Subacute thyroiditis, regardless of type, may produce transitory ultrasound changes that obscure the coexistence of papillary carcinoma. Due to this, initial thyroid ultrasound evaluation should be delayed until clinical recovery. We recommended a thyroid ultrasound exam for initial evaluation of painless thyroiditis, particularly in patients with palpable thyroid nodule. Further cytological examination is recommended in cases presenting with suspect thyroid nodule and/or non-nodular hypoechoic (> 1 cm) or heterogeneous areas with microcalcification focus.

    The most common sites of metastatic differentiated thyroid cancer are the neck lymph nodes, while distant metastases typically involve the lungs, the bones, and less frequently the brain. Uncommon metastatic sites include the liver, adrenal gland, kidney, pancreas, and skin. The epidemiological aspects of thyroid metastases in rare sites are largely unknown and their identification could have a significant impact on patients management. A mini-series of unusual metastatic sites of thyroid carcinoma is proposed as a contribution to current knowledge on anatomopathological characteristics and clinical outcome. Of the six cases that were assessed, the metastases were the following: skin metastases (2), skin and pancreas metastases (1), renal metastasis (1), adrenal metastasis (1), and liver metastasis (1). In our experience, metastases in rare sites do not always represent a negative prognostic factor for disease outcome. In fact they can occur as single distant lesion and if surgically resectable, their treatment can also lead to local disease remission. PMID:26662609

    The aim of this study was to evaluate the efficacy of different radioactive iodine (I-131) activities used for re-ablation, to compare various combinations of treatment activities, and to identify predictors of re-ablation failure in low- and intermediate-risk differentiated thyroid carcinoma (DTC) patients. The study included 128 consecutive low- and intermediate-risk patients with DTC with ablation failure after total thyroidectomy. Patient characteristics, T status, tumor size, lymph node involvement, postoperative remnant size on whole-body scintigraphy, serum thyroglobulin (Tg), thyroid-stimulating hormone (TSH), anti-Tg antibody (TgAb), and Tg/TSH ratio were analyzed as potential predictors of the re-ablation success. Re-ablation was successful in 113 out of 128 patients (88.3 %). Mean first I-131 activity was 2868 ± 914 MBq (77.5 ± 24.7 mCi) and mean second I-131 activity 3004 ± 699 MBq (81.2 ± 18.9 mCi). There was no association between the first, second, and cumulative activity with re-ablation treatment outcome. Treatment failure was associated with higher Tg levels prior to re-ablation (Tg2) (OR 1.16, 95 % CI 1.05-1.29, P = 0.003) and N1a status (OR 3.89, 95 % CI 1.13-13.41, P = 0.032). After excluding patients with positive-to-negative TgAb conversion, Tg2 level of 3.7 ng/mL predicted treatment failure with a sensitivity of 75.0 %, specificity of 80.5 %, and a negative predictive value of 97.1 %. Patients with positive-to-negative TgAb conversion had higher failure rates (OR 2.96, 95 % CI 0.94-9.29). Re-ablation success was high in all subgroups of patients and I-131 activity did not influence treatment outcome. Tg may serve as a good predictor of re-ablation failure. Patients with positive-to-negative TgAb conversion represent a specific group, in whom Tg level should not be used as a predictive marker of treatment outcome. PMID:26732041

    Bone mineral density (BMD) seems not to be decreased in young patients given long-term suppressive doses of levothyroxine (LT4), but information regarding the bone microstructure in these patients is lacking. The aim of this study was to determine whether supraphysiologic doses of LT4, initiated during childhood or adolescence for treatment of differentiated thyroid carcinoma (DTC), have any detrimental effects on bone microarchitecture as evaluated by high-resolution peripheral quantitative computed tomography (HR-pQCT). Seventeen patients (27.3 ± 7.1 years old) with DTC with subclinical hyperthyroidism since adolescence and 34 healthy volunteers matched for age, sex, and body mass index were studied by dual-energy X-ray absorptiometry (DXA) to determine the areal BMD at the lumbar spine, hip, and proximal third of the radius. Volumetric BMD and structural parameters of the trabecular and cortical bone were assessed by HR-pQCT of the distal radius and distal tibia. DTC patients were given suppressive doses of LT4 starting at a mean age of 12.6 years, and the mean duration of treatment was 14.2 years. In DTC patients, clinical parameters did not correlate with DXA or HR-pQCT parameters. No differences were found between the patients and controls with respect to BMD and Z scores at any site evaluated by DXA, and no differences were found in the bone microstructure parameters evaluated by HR-pQCT. This cross-sectional study suggests that long-standing suppressive therapy with LT4 during the attainment of peak bone mass may have no significant adverse effects on bone density or microarchitecture.

    Only three examples of acinic cell carcinoma of the larynx or trachea are found in the recent literature. A case of acinic cell carcinoma of the subglottic larynx and trachea was diagnosed and treated at the University of Virginia Medical Center. To our knowledge this is the first such case with a prior history of radiation to the neck. The patient is a 56-year-old woman who was irradiated for hyperthyroidism 46 years ago. When seen she also had parathyroid hyperplasia and multiple thyroid adenomas, conditions that frequently follow irradiation of the thyroid in children. These findings in this case support the concept that radiation may be responsible for inducing this tumor, which otherwise rarely occurs in this location. The use of electron microscopy was extremely useful in the diagnosis of this tumor. She was treated with total laryngectomy and right neck dissection and is now free of disease one year after surgery.

    ETV6-NTRK3 fusion was identified in several cancers including the recently described mammary analog secretory carcinoma (MASC) of the salivary glands and a minority of papillary thyroid carcinomas. We describe three cases of primary MASC of the thyroid gland and provide a detailed clinical and pathological characterization of the tumor morphology, immunoprofile, and genetic background. Immunohistochemistry for PAX8, TTF-1, thyroglobulin, mammaglobin, GCDFP-15, S-100 protein, and p63 was used to define the tumor immunophenotype. Fluorescence in situ hybridization for ETV6 rearrangement was performed in three, and the next-generation sequencing assay MSK-IMPACT™ (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets) was performed in two cases. Primary MASC of the thyroid occurred in two women and one man, age 47-72 years. All patients presented with high T stage, infiltrative, locally aggressive tumors with extrathyroidal extension. Two cases were associated with well-differentiated papillary thyroid carcinoma. Histologically, they appeared as low-grade tumors, resembling MASC of the salivary glands and labeled positive for mammaglobin, GCDFP-15, S-100 protein, p63, weakly positive for PAX8, and negative for TTF-1 and thyroglobulin. Fluorescence in situ hybridization revealed ETV6 rearrangement in all cases. In two tested cases MSK-IMPACT™ confirmed the presence of ETV6-NTRK3 gene fusion. Two patients had at least two local recurrences, one was alive with disease, and one was alive and free of disease after 14 and 17 years, respectively. The third patient was alive and free of disease after 2 years. MASC of the thyroid is histologically, immunophenotypically, and genetically similar to its salivary gland counterpart. Thyroid MASC can be associated with a well-differentiated papillary thyroid carcinoma component, supporting follicular cell origin.

    Anaplastic thyroid carcinoma (ATC) is a rare, poorly differentiated type of thyroid cancer occurring in less than 5% of all thyroid cancers. Patients typically have a poor prognosis with very few options for treatment.2 With current therapy of surgery, chemotherapy, and radiation, median survival is only 6 months from the time of diagnosis. Several mutations in cell cycle regulation have been discovered in ATC that contribute to its undifferentiated state, one of which is the BRAF kinase mutation. This mutation results in activation of the MAPK pathway and uncontrolled cell proliferation. In this case report, a 51 y old male presented with a 2-week history of hoarseness and was diagnosed with ATC. Genetic analysis revealed a mutation in BRAF kinase; the patient subsequently began therapy with vemurafenib, a BRAF kinase inhibitor indicated for melanoma. After an initial response, the patient quickly declined and consequently died from his disease. Anaplastic thyroid carcinoma is a deadly cancer without an effective treatment. Inhibiting mutated enzymes that drive the development of this cancer is a potential drug target that may improve outcomes in patients with ATC. PMID:26176686

    Human medullary thyroid carcinomas from 19 patients were analyzed for their content in somatostatin (SRIF) receptors using receptor autoradiography with a SRIF-28 analogue and the SRIF octapeptide (Tyr3)-SMS 201-995 as iodinated radioligands. Four out of 19 cases were SRIF receptor positive with the SRIF octapeptide radioligand. These cases as well as four additional tumors were also positive with the SRIF-28 radioligand 125I-(Leu8, D-Trp22, Tyr25)-SRIF-28. High affinity binding sites pharmacologically specific for bioactive SRIF analogues, specifically located on tumor tissue, were identified. In some cases the SRIF receptors were distributed in a non-homogeneous pattern, with labelling occurring preferentially in highly differentiated tumor regions. Numerous cases were shown to have a high tumoral SRIF content measured by radioimmunoassay or immunohistochemical technique. However, there was no correlation between SRIF receptor status and tumor levels of endogenous SRIF. No correlation was seen between the clinical outcome or the survival of the patients and their tumoral SRIF receptor content. Whereas some medullary thyroid carcinomas seem to be a target for SRIF, the SRIF function in these tumors remains unclear. SRIF receptors in a group of medullary thyroid carcinomas may be useful morphological marker of these tumors and of potential interest for their in vivo localization.

    During the years 1969-1975, 58 patients were treated for thyroid carcinoma. 48 patients had differentiated and 10 had anaplastic carcinomas. The material is presented with special attention given to diagnostic methods and treatment for the differentiated forms. The value of cytological examination of fine needle biopsy is clearly documented. 40 patients with differentiated carcinomas were treated with total thyroidectomy, with low complication rate. Accidental persistent recurrent nerve paralysis as well as persistent hypoparathyroidism occurred in less than 3%, Subdivision of papillary and follicular carcinomas on the basis of their local growth pattern is emphasized as being of value in the determination of subsequent therapy.

    The authors have previously shown that the definition of ablation of thyroid tissue in patients treated with thyroidectomy and radioiodine (I-131) for thyroid carcinoma depends upon the dose of I-131 used to scan the patient. The therapeutic response to I-131 therapy was evaluated in a group of ten differentiated thyroid cancer patients who had a negative 2-mCi (-2 mCi) diagnostic study, but had a positive 10-mCi (+10 mCi) diagnostic study (group 1) during their follow-up evaluation. These results were compared to another group of ten differentiated thyroid cancer patients who received I-131 ablation therapy based on a positive 2-mCi (+2 mCi) I-131 scan (group 2). Six patients in group 1 and eight in group 2 had improvement or ablation of residual tissue based on the 10-mCi scan following therapy. The difference in response between the two groups was not statistically significant (P = 0.63) by two-tailed Fisher's exact test, indicating that even patients with -2-mCi, but +10-mCi scans may respond to I-131 therapy. Whether the large dose therapy makes any impact on the clinical outcome has not been answered by this study.

    A 37-year-old man with papillary carcinoma in an ectopic thyroid is presented. Excisional biopsy revealed the cervical mass to be a metastasis from thyroid cancer. X-ray, ultrasonography, and computed tomography, however, failed to identify the primary tumor in the thyroid. Incidental TI-201 uptake was noted in the midline of the anterior neck, and a palpable nodule was discovered in this area. Fine needle aspiration cytology demonstrated Class V papillary adenocarcinoma, and subsequent surgery confirmed a papillary carcinoma in the ectopic thyroid. This case suggests the usefulness of TI-201 scintigraphy for the detection of ectopic thyroid malignancy.

    Understanding the molecular mechanisms involved in thyroid cancer progression may provide targets for more effective treatment of aggressive thyroid cancers. Epithelial-mesenchymal transition (EMT) is a major pathologic mechanism in tumor progression and is linked to the acquisition of stem-like properties of cancer cells. We examined expression of ZEB1 which activates EMT by binding to the E-box elements in the E-cadherin promoter, and expression of E-cadherin in normal and neoplastic thyroid tissues in a tissue microarray (TMA) which included 127 neoplasms and 10 normal thyroid specimens. Thyroid follicular adenomas (FA, n=32), follicular thyroid carcinomas (FTC, n=28), and papillary thyroid carcinomas (PTC, n=57) all expressed E-cadherin and were mostly negative for ZEB1 while most anaplastic thyroid carcinomas (ATC, n=10) were negative for E-cadherin, but positive for ZEB1. A validation set of 10 whole sections of ATCs showed 90% of cases positive for ZEB1 and all cases were negative for E-cadherin. Analysis of three cell lines (normal thyroid, NTHY-OR13-1; PTC, TPC-1 and ATC, THJ-21T) showed that the ATC cell line expressed the highest levels of ZEB1 while the normal thyroid cell line expressed the highest levels of E-Cadherin. Quantitative RT-PCR analyses showed that Smad7 mRNA was significantly higher in ATC than in any other group (p<0.05). These results indicate that ATCs show evidence of EMT including decreased expression of E-cadherin and increased expression of ZEB1 compared to well differentiated thyroid carcinomas and that increased expression of Smad7 may be associated with thyroid tumor progression.

    Anaplastic thyroid carcinoma is a highly aggressive cancer accounting for 1-2% of thyroid malignancies. Cutaneous metastases from anaplastic thyroid carcinoma are exceedingly rare. We report a 65-year-old woman with anaplastic thyroid carcinoma (BRAF V600E mutation) who had lymph node metastases (pT4 N1b) treated by total thyroidectomy, postoperative radiotherapy, adjuvant chemotherapy (paclitaxel and pazopanib) and targeted therapy (vemurafenib). Nine months after initial diagnosis, radiographic studies revealed multiple pulmonary metastases. A dermatologic examination showed a solitary 1.2-cm chest nodule. Skin biopsy from this nodule revealed infiltrative dermal spindle cells arranged in poorly formed fascicles. Immunohistochemical studies demonstrated the tumor cells to be PAX-8 (+), pancytokeratin (+, focally), TTF-1 (-) and SOX-10 (-). Comparison with the patient's primary anaplastic thyroid carcinoma revealed focal areas of poorly differentiated spindle cells morphologically similar to the malignant spindle cells in the skin biopsy. Together, these findings confirmed the diagnosis of anaplastic thyroid carcinoma metastatic to skin. Cutaneous metastasis of anaplastic thyroid carcinoma composed exclusively of spindle cells broadens the histologic differential diagnosis of cutaneous spindle cell malignancies and presents further diagnostic challenges. PAX-8 may be useful in discerning the spindle cell component of anaplastic thyroid carcinoma from other spindle cell malignancies in the skin. PMID:26347145

    Extrathyroidal extension (ETE) of papillary thyroid carcinoma (PTC) is common and clinical presentation can vary from minimal to extensive locoregional involvement. Although PTC is generally considered the most benign among all thyroid carcinomas, it may present with local invasion with poor prognosis. Our retrospective study involved 3267 PTC patients undergoing regular follow-up at Chang Gung Medical Center in Linkou, Taiwan. Among them, 269 were PTC cases with ETE, having tumors greater than 1 cm in size and treated with total or complete thyroidectomy with or without lymph node dissection for which the follow-up period was over 10 years. The mean age of 269 cases was 46.8 ± 15.1 (range 11-83 years) years. The number of females was 204 (75.8 %). Patients were categorized into minimal ETE (175 cases) and extensive ETE (94 cases) groups according to surgical findings and pathological reports. Mean follow-up period was 13.3 ± 5.5 (range 0.2-29.3) years, during which 28 (10.4 %) patients died of thyroid cancer; and 63 (23.4 %) of all-cause mortality. Multivariate analysis showed that age, gender, extensive ETE, and lymph node metastasis had a statistically significant effect on thyroid cancer mortality. Survival rates were significantly different between minimal ETE and extensive ETE groups (p < 0.0001). In conclusion, perithyroidal soft tissue involvement by PTC is an important factor that determines patient prognosis and a closer follow-up and more aggressive treatment is necessary for patients who are old, male, extensive ETE, and with lymph node involvement.

    Background Orthotopic mouse models of human cancer represent an important in vivo tool for drug testing and validation. Most of the human thyroid carcinoma cell lines used in orthotopic or subcutaneous models are likely of melanoma and colon cancer. Here, we report and characterize a novel orthotopic model of human thyroid carcinoma using a unique thyroid cancer cell line. Methods We used the cell line 8505c, originated from a thyroid tumor histologically characterized by anaplastic carcinoma cell features. We injected 8505c cells engineered using a green fluorescent protein–positive lentiviral vector orthotopically into the thyroid of severe combined immunodeficient mice. Results Orthotopic implantation with the 8505c cells produced thyroid tumors after 5 weeks, showing large neck masses, with histopathologic features of a high-grade neoplasm (anaplasia, necrosis, high mitotic and proliferative indexes, p53 positivity, extrathyroidal invasion, lymph node and distant metastases) and immunoprofile of follicular thyroid cell origin with positivity for thyroid transcription factor-1 and PAX8, and for cytokeratins. Conclusions Here we describe a novel orthotopic thyroid carcinoma model using 8505c cells. This model can prove to be a reliable and useful tool to investigate in vivo biological mechanisms determining thyroid cancer aggressiveness, and to test novel therapeutics for the treatment of refractory or advanced thyroid cancers.

    Background Aquaporin3 (AQP3) and Aquaporin4 (AQP4) play a major role in transcellular and transepithelial water movement as water channel membrane proteins. Little is known of their expression and significance in human thyroid tissues. Thus, we examined the expression of AQP3 and AQP4 in normal, hyperplastic and neoplastic thyroid tissues in conjunction with human thyroid cancer cell lines. Methods and Results Immunohistochemical analyses demonstrated AQP3 in the cytoplasmic membrane of normal C cells, but not in follicular cells. In contrast, AQP4 was not found in C cells but was identified in normal follicular cells. AQP4 was positive in 92% of Graves’ disease thyroids and 97% of multinodular goiters, and we failed to demonstrate AQP3 in these hyperplastic tissues. In neoplastic thyroid lesions, we observed AQP3 in 91% of medullary thyroid carcinomas but in no other follicular cell tumors. AQP4 was demonstrated in 100% of follicular adenomas, 90% of follicular carcinomas, and 85% of papillary carcinomas, while it was negative in all medullary carcinomas and undifferentiated carcinomas. Reverse transcriptase polymerase chain reaction (RT-PCR) analyses revealed AQP3 mRNA expression only in medullary carcinomas and AQP4 mRNA expression in follicular cell-derived tumors except for undifferentiated carcinomas. In thyroid cancer cell lines, using RT-PCR and western blotting, AQP3 mRNA and protein were only identified in the TT cell line (human medullary carcinoma cell line) and AQP4 in the other cell lines. In addition, AQP3 mRNA expression was up-regulated by FBS and calcium administration in both a dose and time dependent manner in TT cells. Conclusion The differential expressions of AQP3 and AQP4 may reflect the biological nature and/or function of normal, hyperplastic, and neoplastic thyroid cells and additionally may have value in determining differential diagnoses of thyroid tumors.

    2013-01-01

    Background Differential diagnosis between malignant follicular thyroid cancer (FTC) and benign follicular thyroid adenoma (FTA) is a great challenge for even an experienced pathologist and requires special effort. Molecular markers may potentially support a differential diagnosis between FTC and FTA in postoperative specimens. The purpose of this study was to derive molecular support for differential post-operative diagnosis, in the form of a simple multigene mRNA-based classifier that would differentiate between FTC and FTA tissue samples. Methods A molecular classifier was created based on a combined analysis of two microarray datasets (using 66 thyroid samples). The performance of the classifier was assessed using an independent dataset comprising 71 formalin-fixed paraffin-embedded (FFPE) samples (31 FTC and 40 FTA), which were analysed by quantitative real-time PCR (qPCR). In addition, three other microarray datasets (62 samples) were used to confirm the utility of the classifier. Results Five of 8 genes selected from training datasets (ELMO1, EMCN, ITIH5, KCNAB1, SLCO2A1) were amplified by qPCR in FFPE material from an independent sample set. Three other genes did not amplify in FFPE material, probably due to low abundance. All 5 analysed genes were downregulated in FTC compared to FTA. The sensitivity and specificity of the 5-gene classifier tested on the FFPE dataset were 71% and 72%, respectively. Conclusions The proposed approach could support histopathological examination: 5-gene classifier may aid in molecular discrimination between FTC and FTA in FFPE material. PMID:24099521

    The last few years have witnessed numerous publications addressing the management of thyroid nodules and differentiated thyroid cancers. The purpose of this review is to provide a simplified summary of the newly released guidelines by the American Thyroid Association. A systematic approach has been recommended to evaluate a thyroid nodule through clinical assessment, measurement of serum Thyroid Stimulating Hormone, neck ultrasonography and Fine Needle Aspiration where appropriate. This is followed by cytology analysis using the Bethesda scoring system to detect malignancy. Once diagnosed, thyroid cancers need to be staged and risk stratification needs to be applied to develop further treatment plans. Lastly, several recommendations have been presented to assure proper follow-up and support for thyroid cancer patients regardless of the treatment received. PMID:27607088

    The incidence of well-differentiated thyroid cancer has seen a worldwide increase in the last three decades. Whether this is due to a ‘true increase’ in incidence or simply increased detection of otherwise subclinical disease remains unclear. The treatment of thyroid cancer revolves around appropriate surgical intervention, minimising complications and the use of adjuvant therapy in select circumstances. Prognostic features and risk stratification are crucial in determining the appropriate treatment. There continues to be considerable debate in several aspects of management in these patients. Level 1 evidence is lacking, and there are limited prospective data to direct therapy, hence limiting decision-making to retrospective analyses, treatment guidelines based on expert opinion and personal philosophies. This overview focuses on the major issues associated with the investigation of thyroid nodules and the extent of surgery. As overall survival in well-differentiated thyroid cancer exceeds 95%, it is important to reduce over-treating the large majority of patients, and focus limited resources on high-risk patients who require aggressive treatment and closer attention. The onus is on the physician to avoid treatment-related complications from thyroid surgery and to offer the most efficient and cost-effective therapeutic option. PMID:20381323

    2015-07-01

    Papillary thyroid carcinoma (PTC) is the most common form of thyroid cancer, accounting for greater than 80% of cases. Surgical resection, with or without postoperative radioiodine therapy, remains the standard of care for patients with PTC, and the prognosis is generally excellent with appropriate treatment. Despite this, significant numbers of patients will not respond to maximal surgical and medical therapy and ultimately will die from the disease. This mortality reflects an incomplete understanding of the oncogenic mechanisms that initiate, drive, and promote PTC. Nonetheless, significant insights into the pathologic subcellular events underlying PTC have been discovered over the last 2 decades, and this remains an area of significant research interest. Chromosomal rearrangements resulting in the expression of fusion proteins that involve the rearranged during transfection (RET) proto-oncogene were the first oncogenic events to be identified in PTC. Members of this fusion protein family (the RET/PTC family) appear to play an oncogenic role in approximately 20% of PTCs. Herein, the authors review the current understanding of the clinicopathologic role of RET/PTC fusion proteins in PTC development and progression and the molecular mechanisms by which RET/PTCs exert their oncogenic effects on the thyroid epithelium.

    Collision tumours are a rare entity, in this report, we describe a case of 73-year-old woman presented with a rapid enlargement of left upper cervical lymph node (LN) associated with right thyroid nodular goiter. The histopathological examination of the excised LN showed definite areas of papillary thyroid carcinoma admixed with moderately differentiated squamous cell carcinoma (SCC). Thyroglobulin immunostaining was positive in papillary carcinomatous areas confirming thyroid gland as a source of metastasis. Then the patient underwent total thyroidectomy and neck dissection, which revealed multicentric classic papillary thyroid carcinoma with an absence of squamous differentiation on extensive sampling. The patient received adjuvant radioactive iodine, but the neck swelling was rapidly progressing, ulcerated and infected. Computed tomography (CT) revealed left large cervical amalgamated LN and two metastatic lung nodules, the patient received 2 cycles of chemotherapy and was planned for external beam radiotherapy but she died within 7 months of first presentation. Collision tumours pose a diagnostic as well as therapeutic challenge and carry a rapidly progressive course and a fatal outcome. SCC is considered as a dedifferentiation of papillary thyroid carcinoma, which may appear in metastatic site rather than the primary site. PMID:27042475

    AIMS: To examine neuroendocrine differentiation, as shown by chromogranin A (CGA) expression, in cervical carcinomas. METHODS: Sixty seven cervical carcinomas were studied and were classified as adenocarcinomas, adenosquamous carcinomas or squamous cell carcinomas based on the assessment of haematoxylin and eosin staining and stains for mucin. Where features of glandular differentiation were identified, sections were also stained for evidence of intestinal type mucin. CGA immunostaining was done and the results were graded on a three point scale: 0, + (1-5% of cells positive) and ++ (> 5% of cells positive). These findings were then analysed with respect to lymph node status, tumour differentiation and clinical outcome. RESULTS: There were 32 adenocarcinomas, 18 adenosquamous carcinomas and 17 squamous cell carcinomas. Positive staining was seen in 14 (20.9%) cases, of which four were strongly positive. All but one case were either adenocarcinomas or adenosquamous carcinomas. There was a trend for CGA positivity to be related to intestinal differentiation but this failed to reach statistical significance. No correlation could be demonstrated between CGA staining and lymph node status, tumour differentiation and clinical outcome. CONCLUSIONS: Neuroendocrine differentiation is common in cervical carcinomas where there is evidence of glandular differentiation. Whilst the numbers in this study are relatively small, the presence of neuroendocrine cells in otherwise typical carcinomas does not seem to have any association with clinical behaviour.

    MicroRNAs (miRNAs) represent a class of short endogenous non-coding RNAs that negatively regulate gene expression at the post-transcriptional level in many biological processes, including proliferation, differentiation, stress response and apoptosis. In this study we analyzed a set of seven miRNA molecules in sera of patients with papillary thyroid cancer, multinodular goiter and healthy controls to identify miRNA molecules that may have utility as markers for PTC. MiR-21 serum levels in the preoperative PTC and MG groups were significantly higher than the control group. Likewise, postoperative levels of miR-151-5p, miR-221 and miR-222 were significantly lower in patients with PTC. When serum miRNA levels were evaluated according to stage, postoperative levels of miR-151-5p and miR-222 were significantly lower in patients with advanced stages of the disease. The miRNA levels were also found associated with the size of the primary tumor. Our data imply that specific miRNA molecules which are differentially expressed in thyroid tumors may play role in the development of papillary thyroid carcinoma. PMID:27162538

    INTRODUCTION: Medullary thyroid carcinoma may occur in a sporadic (s-medullary thyroid carcinoma, 75%) or in a multiple endocrine neoplasia type 2 form (MEN2, 25%). These clinical forms differ in many ways, as s-medullary thyroid carcinoma cases are RET-negative in the germline and are typically diagnosed later than medullary thyroid carcinoma in MEN2 patients. In this study, a set of cases with s-medullary thyroid carcinoma are documented and explored. PURPOSE: To document the phenotypes observed in s-medullary thyroid carcinoma cases from a university group and to attempt to improve earlier diagnosis of s-medullary thyroid carcinoma. Some procedures for diagnostics are also recommended. METHOD: Patients (n=26) with apparent s-medullary thyroid carcinoma were studied. Their clinical data were reviewed and peripheral blood was collected and screened for RET germline mutations. RESULTS: The average age at diagnosis was 43.9 years (± 10.82 SD) and did not differ between males and females. Calcitonin levels were increased in all cases. Three patients presented values that were 100-fold greater than the normal upper limit. Most (61.54%) had values that were 20-fold below this limit. Carcinoembryonic antigen levels were high in 70.6% of cases. There was no significant association between age at diagnosis, basal calcitonin levels or time of disease onset with thyroid tumor size (0.6–15 cm). Routine thyroid cytology yielded disappointing diagnostic accuracy (46.7%) in this set of cases. After total thyroidectomy associated with extensive cervical lymph node resection, calcitonin values remained lower than 5 pg/mL for at least 12 months in eight of the cases (30.8%). Immunocyto- and histochemistry for calcitonin were positive in all analyzed cases. None of the 26 cases presented germline mutations in the classical hotspots of the RET proto-oncogene. CONCLUSION: Our cases were identified late. The basal calcitonin measurements and immunostaining for calcitonin were

    Background: We tried to evaluate the female fertility and genetic risk to the offspring from the exposure to high-dose {sup 131}I by assessing the pregnancy outcomes and health status of the children of female patients with differentiated thyroid cancer who had received therapeutic doses of {sup 131}I. Materials and Methods: From 1967 to 2002, a total of 1,282 women had been treated with {sup 131}I. Of these patients, 692 (54%) were in the reproductive age group (18-45 years). Forty women had a total of 50 pregnancies after high-dose {sup 131}I. Age at presentation ranged from 16 to 36 years (mean, 23 {+-} 4 years). Histopathology was papillary thyroid cancer in 32 cases and follicular thyroid cancer in 8 cases. Results: Single high-dose therapy was given in 30 cases, 2 doses were given in 7 cases, 3 doses were given in 2 cases, and four doses were given in 1 case in which lung metastases had occurred. In 37 patients (92%), disease was successfully ablated before pregnancy. Ovarian absorbed-radiation dose calculated by the MIRD method ranged from 3.5 to 60 cGy (mean, 12 {+-} 11 cGy). The interval between {sup 131}I therapy and pregnancy varied from 7 to 120 months (37.4 {+-} 28.2 months). Three spontaneous abortions occurred in 2 women. Forty-seven babies (20 females and 27 males) were born. Forty-four babies were healthy with normal birth weight and normal developmental milestones. Twenty women delivered their first baby after {sup 131}I therapy. The youngest child in our series is 11 months of age, and the oldest is 8.5 years of age. Conclusions: Female fertility is not affected by high-dose radioiodine treatment, and the therapy does not appear to be associated with any genetic risks to the offspring.

    Systemic vasculitis secondary to thyroid carcinomas is exceptional. We report the case of a 55-year-old woman who presented with systemic vasculitis involving leucocytoclastic cutaneous vasculitis and renal disorders secondary to papillary thyroid carcinoma (PTC). Her symptoms resolved completely after total thyroidectomy. Other causes of vasculitis were excluded. To our knowledge, this is only the second case reported of systemic vasculitis associated with PTC in a paraneoplastic manner. PMID:27416971

    Skull base metastasis from differentiated thyroid carcinoma, including papillary and follicular thyroid carcinoma, is a rare manifestation. Herein, we present three cases of skull base metastasis of papillary thyroid carcinoma. The mean age of the patients was 68.6 (65–74) years, and the mean interval between initial diagnosis and skull base metastasis was 56.3 (28–89) months. Cranial nerve palsies were seen in all patients. Intensity modulated radiation therapy to deliver 6,000–6,600 cGy to the skull base metastasis was given to all patients, in addition to partial resection in one patient. At the time of last follow-up, all skull base metastases were well controlled. PMID:26203287

    Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid. PMID:26589365

    Immunoreactive proteins in follicular cells, fibroblasts and endothelial cells were assessed in canine thyroid carcinomas and healthy thyroid glands. No differences were detected in thyrotropin receptor and thyroglobulin staining between cancer and normal tissues, but expression was higher in follicular cells than in fibroblasts. Fibroblast growth factor-2 staining was more intense in healthy follicular cells than in those of carcinomas. Follicular cells in carcinomas presented two- to three-fold greater staining intensity of thyroid transcription factor-1 and proliferating cell nuclear antigen, respectively, than healthy cells, and a similar trend was found for the latter antigen in fibroblasts. Vascular endothelial growth factor staining was more intense in the endothelial cells of tumours than in those of normal tissues. In conclusion, greater expression of factors related to proliferation and angiogenesis was demonstrated in several cell types within thyroid carcinomas compared to healthy tissues, which may represent mechanisms of tumour progression in this disease.

    Micropapillary carcinoma of thyroid is said to be low risk differentiated thyroid malignancy with excellent prognosis. We report the identification of an isolated FDG avid muscle deposit in a treated case of micropapillary carcinoma of the right lobe and widely invasive follicular carcinoma of the left lobe thyroid gland. Patient was found to have an elevated thyroglobulin level with negative iodine scan (TENIS syndrome) on follow up at 6 months. An 18F FDG PET CT (18 fluorine-fluorodeoxyglucose positron emission computed tomography) whole body study revealed a solitary FDG avid deltoid muscle deposit which was histopathologically confirmed to be metastatic papillary carcinoma. While follicular carcinoma is known to have distant metastases, this may be the first reported case of solitary skeletal metastases from micropapillary carcinoma of thyroid and probably the second reported skeletal muscle deposit from DTC detected on 18F FDG PET CT done following elevated thyroglobulin level and negative 131 iodine WB scan (TENIS). This case also assumes importance because it demonstrates possibility of metastases even from a micropapillary carcinoma in contrast to American Thyroid Association guidelines (2009) which suggests that micropapillary carcinoma of thyroid does not merit further treatment after a Total Thyroidectomy.

    RAC1b is a hyperactive variant of the small GTPase RAC1 known to be a relevant molecular player in different cancers. Previous studies from our group lead to the evidence that its overexpression in papillary thyroid carcinoma (PTC) is associated with an unfavorable prognosis. In the present study, we intended to extend the analysis of RAC1b expression to thyroid follicular neoplasms and to seek for clinical correlations. RAC1b expression levels were determined by RT-qPCR in thyroid follicular tumor samples comprising 23 follicular thyroid carcinomas (FTCs) and 33 follicular thyroid adenomas (FTAs). RAC1b was found to be overexpressed in 33% of carcinomas while no RAC1b overexpression was documented among follicular adenomas. Patients with a diagnosis of FTC were divided into two groups based on longitudinal evolution and final outcome. RAC1b overexpression was significantly associated with both the presence of distant metastases (P = 0.01) and poorer clinical outcome (P = 0.01) suggesting that, similarly to that previously found in PTCs, RAC1b overexpression in FTCs is also associated with worse outcomes. Furthermore, the absence of RAC1b overexpression in follicular adenomas hints its potential as a molecular marker likely to contribute, in conjunction with other putative markers, to the preoperative differential diagnosis of thyroid follicular lesions.

    The reported incidence of thyroid carcinoma in Hashimoto's thyroiditis varies widely. For this reason the specific subpopulation of patients with Hashimoto's thyroiditis and a solitary cold nodule was analyzed. Between 1972 and 1984 we operated on 146 consecutive patients with solitary cold nodules and Hashimoto's thyroiditis. There were 47 carcinomas, for an incidence of 32%. The mean age of the 146 patients was 43 1/2 years (median 44 years), with 126 females and 20 males. There was a history of prior head and neck radiation exposure in 54 patients, with a 33% incidence of thyroid carcinoma. The 92 patients without a history of radiation exposure had a 31.5% incidence of carcinoma. The frequency of multicentricity (bilateralism) was 33% in the group that underwent radiation and 24% in the group that did not. To date, with a mean follow-up of 4.7 years, there have been no deaths and no evidence of recurrence. In conclusion, we report a 32% incidence of thyroid carcinoma in patients with Hashimoto's thyroiditis and a solitary cold nodule, with no apparent difference between the patients with or without a history of radiation exposure, although there was a higher incidence of bilateralism (33% versus 24%) in the carcinomas of the patients with a history of head and neck irradiation. We suggest that the operative management of these patients is total thyroidectomy for those with a history of head and neck radiation and thyroid lobectomy for patients with no history of radiation, followed by contralateral lobectomy if a carcinoma is demonstrated.

  10. Nonpalpable thyroid carcinoma: clinical controversies on preoperative selection.

    This article emphasizes some controversies concerning the preoperative selection of nonpalpable thyroid tumors. The prevalence of occult thyroid carcinoma in surgical series (1.8-10%) is not higher than in autopsy thyroid series (2.7-24%). The prevalence of occult thyroid carcinoma in thyroid glands examined in the same institution by ultrasound, for a clinical thyroid abnormality or for investigation of other neck structures without clinically evident or suspected thyroid disease, varies from 3% to 8% and is very similar independent of the fact that a thyroid abnormality is or is not the indication for ultrasonography. These data suggest that the presence of a thyroid disease is not a risk factor for harboring an occult thyroid carcinoma (except for C-cell hyperplasia in the rare case of MEN 2 syndromes). As it is not cost effective to examine all the nonpalpable lesions with fine-needle aspiration (FNA) guided by ultrasounds, it is necessary to define to which extent ultrasound is useful in selecting those lesions to be examined cytologically by FNA. The use of ultrasound to select these lesions is very controversial. Ultrasound-guided cytologic diagnosis of nonpalpable nodules is not as accurate as in the case of palpable nodules. Sampling of material adequate for cytologic analysis depends on the lesion size; it is 64% for a 0.7-cm lesion and it increases to 86.7% for a mean size of 1.1 cm. For the diagnosis of occult thyroid carcinomas (< or =1 cm), sensitivity is 35.8% and false-negative results are 49.3%. Nonpalpable nodules with a size of 1.5 cm represent an absolute indication to perform an ultrasound-guided FNA because this is the size limit for dividing thyroid nodules in probably innocuous or potentially dangerous categories and because the cytologic diagnosis of nodules of this size is sufficiently reliable. For the smaller incidentally discovered thyroid nodules following ultrasound, physicians should discuss with the patient whether and when to

    The cysteine peptidase cathepsin B is important in thyroid physiology by being involved in thyroid prohormone processing initiated in the follicular lumen and completed in endo-lysosomal compartments. However, cathepsin B has also been localized to the extrafollicular space and is therefore suggested to promote invasiveness and metastasis in thyroid carcinomas through, e.g., ECM degradation. In this study, immunofluorescence and biochemical data from subcellular fractionation revealed that cathepsin B, in its single- and two-chain forms, is localized to endo-lysosomes in the papillary thyroid carcinoma cell line KTC-1 and in the anaplastic thyroid carcinoma cell lines HTh7 and HTh74. This distribution is not affected by thyroid stimulating hormone (TSH) incubation of HTh74, the only cell line that expresses a functional TSH-receptor. Immunofluorescence data disclosed an additional nuclear localization of cathepsin B immunoreactivity. This was supported by biochemical data showing a proteolytically active variant slightly smaller than the cathepsin B proform in nuclear fractions. We also demonstrate that immunoreactions specific for cathepsin V, but not cathepsin L, are localized to the nucleus in HTh74 in peri-nucleolar patterns. As deduced from co-localization studies and in vitro degradation assays, we suggest that nuclear variants of cathepsins are involved in the development of thyroid malignancies through modification of DNA-associated proteins.

    Occult thyroid carcinoma is very common in the clinic and is generally divided into four groups. Here, we proposed two types of occult thyroid carcinoma as the fifth group. The first type was locoregional lymph node metastases from thyroid carcinoma, and the second type was distant organ metastases from thyroid carcinoma. The unique aspect of the fifth group was that the primary carcinoma of the fifth group was not finally found by pathological examination. To better understand the fifth group, we reported a typical case. Furthermore, we discussed the diagnostic criteria and procedures and the management of the fifth group of occult thyroid carcinoma.

    Background. BRAF V600E mutation is associated with poor prognosis in patients with papillary thyroid carcinoma (PTC). PTC is often multifocal, and there are no guidelines on how many tumors to test for BRAF mutation in multifocal PTC. Methods. Fifty-seven separate formalin-fixed and paraffin-embedded PTCs from twenty-seven patients were manually macrodissected and tested for BRAF mutation using a commercial allele-specific real-time polymerase chain reaction-based assay (Entrogen, Woodland Hills, CA). Data related to histologic characteristics, patient demographics, and clinical outcomes were collected. Results. All mutations detected were BRAF V600E. Seventeen patients (63%) had concordant mutation status in the largest and second-largest tumors (i.e., both were positive or both were negative). The remaining ten patients (37%) had discordant mutation status. Six of the patients with discordant tumors (22% overall) had a BRAF-negative largest tumor and a BRAF-positive second-largest tumor. No histologic feature was found to help predict which cases would be discordant. Conclusions. Patients with multifocal PTC whose largest tumor is BRAF-negative can have smaller tumors that are BRAF-positive. Therefore, molecular testing of more than just the dominant tumor should be considered. Future studies are warranted to establish whether finding a BRAF mutation in a smaller tumor has clinical significance. PMID:26448939

    Hereditary medullary thyroid carcinoma (MTC) represents up to one-third of MTC cases and includes multiple endocrine neoplasia syndrome type 2A (and its variant familial MTC) and 2B. The aim of this paper is to provide an overview of the disease focusing on the management of hereditary MTC patients, who have already developed tumor, as well as discuss the recommended approach for asymptomatic family members carrying the same mutation. A PubMed search was performed to review recent literature on diagnosis, genetic testing, and surgical and medical management of hereditary MTC. The wide use of genetic testing for RET mutations has markedly influenced the course of hereditary MTC. Prophylactic thyroidectomy of RET carriers at an early age eliminates the risk of developing MTC later in life. Pre-operative staging is a strong prognostic factor in patients, who have developed MTC. The use of recently approved tyrosine kinase inhibitors (vandetanib, cabozantinib) holds promising results for the treatment of unresectable, locally advanced, and progressive metastatic MTC. Genetic testing of the RET gene is a powerful tool in the diagnosis and prognosis of MTC. Ongoing research is expected to add novel treatment options for patients with advanced, progressive disease.

The members of the Working Group have been chosen from the specialists involved in medical care of patients with thyroid carcinoma. Directly before the preparation of the Polish national recommendations the American Thyroid Association (ATA) published its own guidelines together with a wide comment fulfilling evidence-based medicine (EBM) criteria. ATA Guidelines are consistent with National Comprehensive Cancer Network (NCCN) Recommendation. According to the members of the Working Group, it is necessary to adapt them to both the specific Polish epidemiological situation as well as to the rules referring to the Polish health system. Therefore, the Polish recommendations constitute a consensus of the experts' group, based on ATA information. The experts analysed previous Polish Guidelines, published in 2010, and other available data, and after discussion summed up the results in the form of these guidelines. It should be added that Part II, which

    Incidence of differentiated thyroid carcinoma varies considerably between countries and ethnic groups, with particularly high incidence rates in Melanesians of New Caledonia. Differentiated thyroid cancer (DTC) has a familial relative risk higher than other cancers, highlighting the contribution of inherited factors to the disease. Recently, genome-wide association studies (GWAS) identified several DTC susceptibility loci. The most robust associations were reported at loci 9q22 (rs965513 and rs1867277) and 14q13 (rs944289 and rs116909734). In this study, we performed a fine-mapping study of the two gene regions among Europeans and Melanesians from Metropolitan France and New Caledonia. We examined 81 single nucleotide polymorphisms (SNPs) at 9q22 and 561 SNPs at 14q13 in Europeans (625 cases/776 controls) and in Melanesians (244 cases/189 controls). The association with the four SNPs previously identified in GWAS was replicated in Europeans while only rs944289 was replicated in Melanesians. Among Europeans, we found that the two SNPs previously reported at 9q22 were not independently associated to DTC and that rs965513 was the predominant signal; at 14q13, we showed that the haplotype rs944289[C]-rs116909374[C]-rs999460[T] was significantly associated with DTC risk and that the association with rs116909374 differed by smoking status (p-interaction = 0.03). Among Melanesians, a new independent signal was observed at 14q13 for rs1755774 which is strongly correlated to rs2787423; this latter is potentially a functional variant. Significant interactions with parity (p < 0.05) and body mass index were observed for rs1755774 and rs2787423. This study contributed to a better characterization of the DTC loci 9q22 and 14q13 in Europeans and in Melanesians and has identified novel variants to be prioritized for further functional studies.

    The macrofollicular variant of papillary thyroid carcinoma (MFPTC) is a well-established entity with characteristic large follicles containing pale colloid and lined by cells with nuclear features of papillary thyroid carcinoma (PTC). In this study, we present three cases of MFPTC, along with a brief review of the literature. For all three of our cases, the histology of the resected specimen showed predominantly macrofollicular structures lined by cells with nuclear characteristics of PTC. Immunohistochemically, the three cases show positivity for galactin-3, cytokeratin-19, and HBME-1. These cases will help us in understanding the distinction from other benign and malignant follicular lesions of the thyroid, which is of utmost importance. The key to diagnosis is a high-power examination of any macrofollicular lesion of the thyroid. PMID:22048513

    Papillary thyroid carcinoma (PTC) is the most common type of thyroid neoplasias; however, primary thyroid gland lymphoma (PTL) is uncommon and their simultaneous occurrence is very rare.Herein, we reported a 25-year-old female patient with Hashimoto's thyroiditis (HT), who developed a small goiter with a palpable 1.2-cm nodule in the right lobe. A fine-needle aspiration (FNA) biopsy revealed atypical follicular epithelial cells and lymphoid cells in a background of lymphocytic thyroiditis. A total thyroidectomy was performed. The pathology showed multicentric papillary thyroid carcinoma, concomitant thyroid mucosa-associated lymphoid tissue (MALT) lymphoma, and Hashimoto's thyroiditis. Postoperatively, he received chemotherapy and radioactive iodine ablation treatment. Nowadays the thyroglobulin of the patient is undetectable, without recurrences at 2 years of follow-up.It is concluded that the PTC and MALT lymphoma can exist concomitantly, especially in patients with HT. For the diagnostic workup and optional management of this rare coexistence, a multidisciplinary approach and close surveillance are needed. PMID:26717396

    Samples from a biological serum bank taken up to 23 years prior to diagnosis of thyroid carcinoma were analysed for human thyroglobulin, thyroid-stimulating hormone and thyroxin. After exclusions, the final study material consisted of 59 cases of papillary and follicular carcinomas. These cases were compared with 164 controls, matched for sex, age and time of sample taking. The most interesting finding was that concentrations of thyroglobulin in serum were abnormally elevated in cases compared with controls, equal to or above 30 microg/L, with odds ratio 7.0 (CI 3.1-15.7). This elevation of serum thyroglobulin occurred in 44% of the carcinoma cases. Sensitivity was around 50 for measurements taken up to 15 years prior to diagnosis, but 21 when the interval was over 15 years. Specificity was 89. No differences were found between cases and controls in values for thyroid-stimulating hormone and thyroxin. PMID:11207005

We report a patient with an extremely unusual clinical presentation of Hürthle cell carcinoma in thyroid and parathyroid carcinoma. The patient displayed a rare presentation of life-threatening hypercalcaemia after total para-thyroidectomy and failed to respond to standard therapy. Our review of available literature yielded insufficient evidence in managing such. When a patient with thyroid cancer is diagnosed, checking for serum calcium is advised. This is considered a useful method for detecting possible incidental parathyroid lesion and screening the probable concealed parathyroid pathology. PMID:26813941

    Introduction: The American Thyroid Association appointed a Task Force of experts to revise the original Medullary Thyroid Carcinoma: Management Guidelines of the American Thyroid Association. Methods: The Task Force identified relevant articles using a systematic PubMed search, supplemented with additional published materials, and then created evidence-based recommendations, which were set in categories using criteria adapted from the United States Preventive Services Task Force Agency for Healthcare Research and Quality. The original guidelines provided abundant source material and an excellent organizational structure that served as the basis for the current revised document. Results: The revised guidelines are focused primarily on the diagnosis and treatment of patients with sporadic medullary thyroid carcinoma (MTC) and hereditary MTC. Conclusions: The Task Force developed 67 evidence-based recommendations to assist clinicians in the care of patients with MTC. The Task Force considers the recommendations to represent current, rational, and optimal medical practice. PMID:25810047

    Although minimally invasive follicular thyroid carcinoma (MI-FTC) is regarded as an indolent tumour, treatment strategies remain controversial. Our aim was to investigate the outcome for patients with MI-FTC and to identify prognostic parameters to facilitate adequate treatment and follow-up. This retrospective follow-up study involved all cases of MI-FTC operated at the Karolinska University Hospital between 1986 and 2009. Outcome was analysed using death from MI-FTC as endpoint. Fifty-eight patients (41 women and 17 men) with MI-FTC were identified. The median follow-up time was 140 (range 21-308) months. Vascular invasion was observed in 36 cases and was associated with larger tumour size [median 40 (20-76) compared with 24 (10-80) mm for patients with capsular invasion only (P = 0.001)] and older patients [54 (20-92) vs. 44 (11-77) years; P = 0.019]. Patients with vascular invasion were more often treated with thyroidectomy (21/36 compared to 7/22 with capsular invasion only; P = 0.045). Five patients died from metastatic disease of FTC after a median follow-up of 114 (range 41-193) months; all were older than 50 years (51-72) at the time of the initial surgery; vascular invasion was present in all tumours and all but one were treated with thyroidectomy. Univariate analysis identified combined capsular and vascular invasion (P = 0.034), age at surgery ≥50 years (P = 0.023) and male gender (P = 0.005) as related to risk of death from MI-FTC. MI-FTC should not be considered a purely indolent disease. Age at diagnosis and the existence of combined capsular and vascular invasion were identified as important prognostic factors.

    Invasion of the laryngeal framework by thyroid carcinoma requires specific surgical techniques and carries a higher rate of complications that deserve to be highlighted. We reviewed our data from 1995 to 2012 and found six patients with laryngotracheal invasion by thyroid carcinoma. All underwent total thyroidectomy and single-stage cricotracheal resection, plus anterolateral neck dissection. Three had airway obstruction that necessitated prior endoscopic debulking. None of the patients needed a tracheotomy. There were four cases of papillary carcinoma, and two cases of undifferentiated carcinoma. One patient died of complications of the procedure (anastomotic dehiscence and tracheo-innominate artery fistula). Another died 2 months after the procedure from local recurrence and aspiration pneumonia. One case presented recurrence at 15 months, which was managed by re-excision and adjuvant radiotherapy; after 26 months of follow-up, he has no evidence of locoregional recurrence. The three other patients are alive without evidence of disease at 6, 18 and 41 months, respectively. Cricotracheal resection for subglottic invasion by thyroid carcinoma is an effective procedure, but carries significant risks of complications. This could be attributed to the devascularisation of the tracheal wall due to the simultaneous neck dissection, sacrifice of the strap muscles or of a patch of oesophageal muscle layer. We advocate a sternocleidomastoid flap to cover the anastomosis. Cricotracheal resection for subglottic invasion can be curative with good functional outcomes, even for the advanced stages of thyroid cancer. Endoscopic debulking of the airway prior to the procedure avoids tracheotomy. PMID:24129693

    A mixed differentiated thyroid carcinoma was found in a small asymptomatic nodule in a 44-yr-old woman with recurrent chest infections and bronchiectasis. After total thyroidectomy and 162 mCi (6 GBq) radioiodine ablation there was uptake in the thyroid remnant and in both lungs, interpreted as lung metastases. In 2 years she received further three 162 mCi (6 GBq) doses of /sup 131/I, as scans showed very similar lung activity. Another scan, during thyroxin suppression, showed again activity in the lungs. A 47-yr-old male patient with similar respiratory disease and no history of thyroid disorder volunteered to undergo radioiodine scan while on triiodothyronine suppression. His scan, too, showed concentration in the lungs. The female patient died 7 years after the diagnosis of lung thyroid metastases was made. No metastasis was found at autopsy. Radioiodine lung uptake may occur in patients with chronic inflammatory lung disease, presenting a potential diagnostic pitfall in patients with differentiated thyroid carcinoma.

    Background: Recently, VE1, a monoclonal antibody against the BRAFV600E mutant protein, has been investigated in terms of its detection of the BRAFV600E mutation. Although VE1 immunostaining and molecular methods used to assess papillary thyroid carcinoma in surgical specimens are in good agreement, evaluation of VE1 in thyroid cytology samples is rarely performed, and its diagnostic value in cytology has not been well established. In present study, we explored VE1 immunoexpression in cytology samples from ex vivo papillary thyroid carcinoma specimens in order to minimize limitations of low cellularity and sampling/targeting errors originated from thyroid fineneedle aspiration and compared our results with those obtained using the corresponding papillary thyroid carcinoma tissues. Methods: The VE1 antibody was evaluated in 21 cases of thyroid cytology obtained directly from ex vivo thyroid specimens. VE1 immunostaining was performed using liquid-based cytology, and the results were compared with those obtained using the corresponding tissues. Results: Of 21 cases, 19 classic papillary thyroid carcinomas had BRAFV600E mutations, whereas two follicular variants expressed wild-type BRAF. VE1 immunoexpression varied according to specimen type. In detection of the BRAFV600E mutation, VE1 immunostaining of the surgical specimen exhibited 100% sensitivity and 100% specificity, whereas VE1 immunostaining of the cytology specimen exhibited only 94.7% sensitivity and 0% specificity. Conclusions: Our data suggest that VE1 immunostaining of a cytology specimen is less specific than that of a surgical specimen for detection of the BRAFV600E mutation, and that VE1 immunostaining of a cytology specimen should be further evaluated and optimized for clinical use.

    Abstract This was an extremely rare case of unusual granular cell tumor of the trachea coexisting with recurrent papillary thyroid carcinoma. We initially misdiagnosed this patient as having tracheal invasion from recurrent thyroid carcinoma even after a computed tomography scan and fine-needle aspiration cytology. Clinicians should be aware of the possibility of granular cell tumor of the trachea occurring simultaneously with papillary thyroid carcinoma. PMID:27149467

    Aim The aim of the present retrospective study was to assess the feasibility of loboisthmectomy for the treatment of differentiated thyroid cancer in a endemic area, evaluating the histopathological features and the results of a case series of 1154 patients. Patients and Methods The clinical records of 1154 patients submitted to total thyroidectomy in our Department were retrospectively reviewed to analyze the histopathological characters and the results. Results In 1044 cases (90.5%) a papillary cancer was observed, in 110 (9.5%) a follicular carcinoma; microcarcinomas were 399 (34.5%). Multifocality was present in 323 cases (28%), in 142 unilateral (12.3%) and in 181 bilateral (15.7%). Thyroiditis coexisted in 472 patients (40.9%), multinodular goiter in 404 (35%), Graves’ disease in 48 (4.1%), and multinodular toxic goiter in 38 (3.3%). Complications were: postoperative bleeding in 20 patients (1.7%), transient unilateral vocal cord paralysis in 20 (1.7%) definitive in 10 (0.86%), a transient bilateral paralysis in 1 (0.08%), a transient hypoparathyroidism in 351 (30.4%), and a definitive in 24 (2.07%). Nodal recurrence occurred in 25 patients (2.16%). Conclusions Total thyroidectomy remains the safest treatment in differentiated thyroid cancer, especially if performed in high volume centers in which complications can be minimized. Loboisthmectomy can be a viable and safe alternative in small (< 1 cm) unifocal tumors in patients at low risk. Loboisthmectomy is limited in endemic areas by the association with other thyroid diseases. A correct and detailed information of the patient is essential before planning surgery. PMID:26888701

    Benign hypofunctional cold thyroid nodules (CTNs) are a frequent scintiscan finding and need to be distinguished from thyroid carcinomas. The origin of CTNs with follicular morphologic features is unresolved. The DNA damage response might act as a physiologic barrier, inhibiting the progression of preneoplastic lesions to neoplasia. We investigated the following in hypofunctional follicular adenoma (FA) and follicular thyroid cancer (FTC): i) the mutation rate of frequently activated oncogenes, ii) the activation of DNA damage response checkpoints, and iii) the differential proteomic pattern between FA and FTC. Both FTC and FA, which did not harbor RAS, phosphoinositide-3-kinase, or PAX/peroxisome proliferator activated receptor-γ mutations, express various proteins in common and others that are more distinctly expressed in FTC rather than in FA or normal thyroid tissue. This finding is in line with the finding of constitutive DNA damage checkpoint activation (p-Chk2, γ-H2AX) and evidence for replicative stress causing genomic instability (increased cyclin E, retinoblastoma, or E2F1 mRNA expression) in FTC but not FA. We discuss the findings of the increased expression of translationally controlled tumor protein, phosphatase 2A inhibitor, and DJ-1 in FTC compared with FA identified by proteomics and their potential implication in follicular thyroid carcinogenesis. Our present findings argue for the definition of FA as a truly benign entity and against progressive development of FA to FTC. PMID:21983636

    Traditionally, withdrawal of thyroid hormone to increase serum levels of thyroid-stimulating hormone (TSH) has been used in patients with differentiated thyroid carcinoma (DTC) to optimize radio-iodine uptake and serum thyroglobulin (Tg) stimulation during follow-up and in preparation for radio-iodine therapy. However, this procedure is associated with signs and symptoms of hypothyroidism which negatively affect the patient's quality of life. Recombinant human thyrotropin (rhTSH) has provided an effective alternative to thyroid hormone withdrawal. After favourable experimental trials in humans, rhTSH obtained regulatory approval in North America and in Europe as a diagnostic tool, and more recently as a preparation for radio-iodine thyroid remnant ablation. Since then, rhTSH has radically changed the diagnostic and therapeutic management of DTC patients. This review will focus on the clinical application of rhTSH in the management of DTC, highlighting current indications and future perspectives. PMID:19041828

    Metastases to the thyroid are uncommon [<0.2% of thyroid fine needle aspirations (FNA)]. Of metastases to the thyroid, breast carcinoma is relatively common. The diagnosis of metastasis to the thyroid has important therapeutic and prognostic implications. To our knowledge, a morphologic and immunophenotypic comparison of metastatic ductal carcinoma of the breast and primary thyroid carcinomas has not been reported. Here, we report the case of a 37-year-old female with a history of metastatic ductal carcinoma of the breast (modified Bloom-Richardson grade 2; ER+, PgR+, HER2+) diagnosed 6 years prior. She developed hoarseness, prompting a CT scan. Multiple thyroid nodules were found, including a 1.5 cm hypoechoic, solid, irregularly-shaped nodule. On FNA, cells were arranged singly and in crowded groups, varied in size and degree of pleomorphism, and exhibited rare nuclear grooves, inconspicuous nucleoli, and rare intracytoplasmic lumina with no nuclear pseudoinclusions or colloid (Figs. 1A and B). These findings raised the differential of papillary thyroid carcinoma (Fig. 1C), follicular neoplasm (Fig. 1D), medullary carcinoma (Fig. 1E), parathyroid (Fig. 1F), and metastatic breast carcinoma. Immunostaining for GATA-3 (+), ER (+), PAX-8 (-), and TTF-1 (-) was consistent with metastatic breast carcinoma (Fig. 2). We conclude that metastatic breast carcinoma to the thyroid may morphologically mimic primary thyroid carcinoma on FNA; a panel of immunomarkers, such as GATA-3, hormonal marker(s), PAX-8, and TTF-1, may be useful in some cases. GATA-3 immunostaining for metastatic breast carcinoma was helpful in our case and has not been previously reported in a thyroid metastasis sampled by FNA. Diagn.

    Among primary thyroid neoplasms, papillary thyroid carcinoma (PTC) and primary thyroid lymphoma (PTL) are known to coexist and are pathogenetically linked with Hashimoto's thyroiditis (HT). However, HT occurring in association with medullary thyroid carcinoma (MTC) is rarely documented. We report here an interesting case. A 34-year-old female with a solitary thyroid nodule underwent fine needle aspiration cytology (FNAC) that was interpreted as “MTC with admixed reactive lymphoid cells, derived possibly from a pretracheal lymph node.” Total thyroidectomy specimen showed “MTC with coexisting HT.” At a later stage, a follow-up FNAC from the recurrent thyroid swelling showed features consistent with HT. As an academic exercise, the initial smears on which a diagnosis of MTC was offered were reviewed to look for evidence of coexisting HT that showed scanty and patchy aggregates of reactive lymphoid cells without Hürthle cells. Our case highlights an unusual instance of MTC in concurrence with HT that can create a tricky situation for cytopathologists. PMID:27279687

    The aim of this study was to clarify the histopathological features of anaplastic thyroid carcinoma in patients who achieved long-term survival. We reviewed 88 anaplastic thyroid carcinoma cases in which the patient survived less than 3 months (short-term survival), and 68 anaplastic thyroid carcinoma cases in which the patient survived more than one year (long-term survival) from the database of the Anaplastic Thyroid Carcinoma Research Consortium of Japan. We examined these cases both histologically and immunohistochemically. Six (6.8%) short-term survival cases and 27 (39.7%) long-term survival cases were considered not to be anaplastic thyroid carcinoma after central review. Of these, 12 were revised to papillary carcinoma with squamous cell carcinoma. In cases without chemotherapy, long-term survival was significantly more common if there was a pre-existing tumor, epithelial growth, or lymphocytic infiltration, and short-term survival was more common if neutrophilic infiltration was present. In cases with chemotherapy, long-term survival was significantly more common if epithelial growth or a squamous cell carcinoma component was present, whereas short-term survival was more common in cases with rhabdoid cells. Immunohistochemical results were not related to survival. Some long-term survival cases showed histological findings other than those typically associated with anaplastic thyroid carcinoma. The presence of a pre-existing tumor, epithelial growth, a squamous cell carcinoma component, no neutrophilic infiltration and lymphocytic infiltration may therefore be favorable prognostic factors in anaplastic thyroid carcinoma.

    Hashimoto's thyroiditis with thyroid cancer in childhood is not as common in the adult population. Hashimoto's thyroiditis is an autoimmune disease associated with autoantibodies, and the association between Hashimoto's thyroiditis and papillary carcinoma of the thyroid remains controversial. The present study reported a 15-year-old adolescent girl with the diagnosis of Hashimoto's thyroiditis with thyroid cancer. With the complexity of the clinical manifestations of Hashimoto's thyroiditis, it can be expressed as not only hyperthyroidism or hypothyroidism, but also normal thyroid function. The long-term treatment, and for children with thyroid cancer, early diagnosis is particularly difficult. In the present case, the diagnosis of Hashimoto's thyroiditis is primarily based on clinical manifestations, anti-thyroglobulin antibody and anti-thyroid microsomal antibody. The only diagnostic imaging ultrasound was negative. The present study discussed the possible reason and the identification of this unique case of Hashimoto's thyroiditis with thyroid cancer.

    Focal hot nodules on iodine thyroid images are associated with an exceedingly low incidence of malignancy. Most previously reported hot carcinomas represent the coexistence of small malignancies in or adjacent to a benign hot lesion. Described here is a 3-cm papillary carcinoma that fulfilled the criteria for benignancy on Tc-99m and I-123 imaging. Coincidental carcinoma within a benign lesion was excluded by detailed scintigraphic-pathologic correlation of the tumor. The implications of this case on the management of the solitary hot nodule are discussed and the literature reviewed.

    Incidence of unexpected diagnosis of thyroid carcinoma among operations on benign thyroid surgical diseases (nodular goiter and Graves' disease) was studied in 608 patients within 2008-2009 years in specialized clinic of endocrine surgery. In 56 (9.2%) patients the "incidental" thyroid carcinoma including 43 (77%) - papillary microcarcinoma were diagnosed in histological investigations. In 10 (18%) patients which were performed within the first postoperative week. Repeated surgery demonstrates increased risk of complication (damage of parathyroid glands, recurrent laryngeal nerves and other anatomic structures of neck) considering less favoring conditions for secondary operations, it is worth to implement wider indications to frozen section, radical primary operation (total thyroidectomy at multi-nodular bilateral goiter and Graves' disease), and also maximal complete examination prior to surgery.

    Over a period of 25 years (1961-1986), 30 consecutive patients were operated upon for solitary HOT nodules. The autonomy of these nodules was substantiated by cytomel nonsuppressibility on /sup 131/I or /sup 123/I scanning, or TSH stimulated enhancement of the remaining suppressed thyroid tissue (n = 24); or as a solitary toxic hot nodule with suppression of the remaining thyroid tissue (n = 6). Seventeen of these patients were euthyroid and 13 were thyrotoxic and required preoperative preparation with antithyroid medication. Five patients had a history of head and neck irradiation. The population consisted of 24 women and six men. Their ages ranged from 14 to 68 years. The tumors ranged in size from 1.5 to 7 cm. The pathologic findings consisted of colloid adenoma in nine patients, follicular adenoma in 19 patients, and a follicular carcinoma in two patients, for an incidence of 6 per cent. It is of interest that neither of the patients with thyroid carcinoma were toxic or had a history of radiation exposure. These findings support the concept that the incidence of carcinoma in truly autonomous HOT thyroid nodules is not negligible.

    Background: Findings of recent studies have demonstrated a rapid increase of the incidence of papillary thyroid carcinoma (PTC), which accounts for nearly 80% of thyroid cancers. Objectives: The aim of this study was to explore the association between AXIN2 gene polymorphism and papillary thyroid carcinoma (PTC). Patients and Methods: 106 blood samples (56 PTC patients and 50 healthy controls) were drawn from China-Japan Union Hospital in Jilin province, China, during October 2010 to March 2011. A case-control study was designed to examine the association between AXIN2 and PTC. Seven tag single nucleotide polymorphisms (tag SNPs) in AXIN2 were selected and genotyped. Frequencies of different genotypes and alleles were analyzed between the patients and the controls, using the R × C column contingency table χ2 test. The possible association of haplotypes constructed by the combined effects of two or more loci with PTC was analyzed through the UNPHASED 3.1.4 program. Results: Rs11655966, rs3923086 and rs7591 of AXIN2 showed significant associations with PTC (P < 0.05). The result of haplotypes analysis showed that rs11655966-rs3923086-rs4791169 had statistically significant differences between the two groups (P < 0.05). Conclusions: Together with the functions of the target genes, we further elucidated that AXIN2 is associated with papillary thyroid carcinoma in the Chinese Han population. PMID:27168945

    Abstract Thyroid-like follicular carcinoma of the kidney (TLFCK) is an extremely rare subtype of renal cell carcinoma with close resemblance to the well-differentiated thyroid follicular neoplasms. TLFCK has not been included in the 2004 World Health Organization (WHO) classification due to the limited data available. Only 27 cases have been reported in the literature to date. Herein, we report a unique case of TLFCK that presented as a striking skull and meningeal metastasis 5 years after the initial diagnosis; this is the first case of TLFCK with such a novel metastasis pattern. A 68-year-old woman was found to have a right renal lesion using computed tomography (CT) during her regular clinical follow-up visit for bladder cancer, but she exhibited no obvious clinical symptoms. The CT scan showed a 4.4-cm diameter, slightly lobulated soft tissue mass in the right lower kidney, the pathological findings of which showed a TLFCK. Five years later, the patient had progressed to skull and meningeal metastasis. Both the renal tumor and the metastasis lesion were composed almost entirely of follicles with a dense, colloid-like material that resembled thyroid follicular carcinoma. However, no lesion was found in the thyroid gland. The neoplastic epithelial cells were strongly immunoreactive for cytokeratin 7 (and vimentin but negative for thyroid transcription factor-1 and thyroglobulin. This is the first reported case of TLFCK to consist of widespread metastases to the skull and meninges and provides evidence that this rare variant of renal cell carcinoma has uncertain malignant potential and can be more clinically aggressive than previously believed.

    The adrenal gland is an uncommon site of metastasis from differentiated thyroid carcinoma, and I-avid adrenal metastatic lesions are even rarer. Here, we describe a 54-year-old woman with I-avid adrenal metastasis from follicular thyroid carcinoma identified using I whole-body scan (I-WBS) and I-SPECT/CT. I-SPECT/CT allowed superior localization of the equivocal I uptake in the I-WBS. It provides metabolic and anatomic information about a lesion, resulting in accurate localization and improved definition of I-WBS findings. PMID:22889799

    Prophylactic neck dissection (PND) for papillary thyroid carcinoma (PTC) is controversial. Our aim was to assess current levels of evidence (LE) according to the Oxford Centre for Evidence-based Medicine (http://www.cebm.net/?O=1025) regarding the oncologic benefits of PND. Data were analyzed via MEDLINE key-words: PTC, differentiated thyroid carcinoma, PND, central lymph node metastases, central compartment, recurrence-free survival. There was conflicting evidence regarding the rate of reoperation for recurrence, with some studies showing a lower rate after PND with increased recurrence-free survival and a higher rate of undetectable pre- and post-ablation thyroglobulin levels (LE 4), whereas other studies did not show a difference (LE 4). Only one study (LE 4) showed improved disease-specific survival with PND. PND may improve recurrence-free survival, although this is supported by only a low LE. Current recommendations can only be based on low-level evidence. PMID:25022716

    Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only rare cases of ectopic PTC without any evidence of occult thyroid cancer in the orthotopic thyroid or cervical lymph nodes have been reported. We report on a 39 year old woman who was operated for a mediastinal mass. The initial diagnosis was a malignant thymic lesion, which was later confirmed to be a papillary thyroid carcinoma. Consequently, total thyroidectomy was performed and pathology report showed normal thyroid tissue with no evidence of any neoplastic involvement. Until now, only one similar case has been reported.

    Spindle epithelial tumor with thymus-like differentiation (SETTLE) is a rare tumor of the thyroid gland which occurs predominantly in children, adolescents, and young adults. It usually presents as a painless neck or thyroid mass and only exceptionally as a diffusely enlarged thyroid gland, without metastatic disease at diagnosis. We report on the case of 12-yr-old girl who had diffusely enlarged thyroid gland for about 1 yr and was initially treated for thyroiditis. Fine-needle aspiration biopsy (FNAB) was performed 8 mo after the first admission. Cytological examination of smears showed unusual morphological features. FNAB smears were cellular, with dissociated cells, naked oval nuclei, aggregates, and groups. Three main cell types were observed: spindle, epithelioid, and epithelial. These cells were uniform, cytologically bland, with few mitotic figures. The distinction between these cells was not always unequivocal. In the background of the smears abundant red extracellular material in the form of fine, dust-like granules and irregular patches were present. It was also observed in some aggregates and groups of tumor cells. Spindle and epithelioid cells were immunocytochemically diffusely pan-cytokeratin-positive. In the differential diagnosis, medullary thyroid carcinoma and SETTLE were suggested. The final histological diagnosis was SETTLE. In cases of SETTLE presented as a diffuse thyromegaly the correct diagnosis may be delayed because clinically and ultrasonographically thyroiditis is suspected. To avoid such a delay, FNAB should be used preoperatively. It can provide specific cytological diagnosis based on morphological features and certain immunocytochemical characteristics of the tumor.

    Introduction We report a case of malignant melanoma arising in medullary thyroid carcinoma that has not yet been described. Presentation of case A 66-year-old woman presented with a mass in her thyroid. The resected mass was black in color, and was composed of a mixture of classic medullary thyroid carcinoma and pleomorphic atypical cells containing melanin pigments. The pleomorphic atypical cells were morphologically consistent with malignant melanoma, and expressed Melan-A, HMB-45, and S-100 protein as determined by immunohistochemistry. Some of these cells were also positive for calcitonin and chromogranin A. Although the malignant melanoma metastasized to the lymph nodes, the patient remained free from local recurrence and distant metastasis and the primary malignant melanoma lesion was not identified for up to 11 years after the thyroidectomy. Discussion 11 melanin-producing MTC cases have been reported to date. In the reported cases, the term “malignant melanoma” was not used, likely because the melanin-containing carcinoma cells were not morphologically consistent with malignant melanoma, but with medullary carcinoma. Conclusion Malignant melanoma arising in MTC may have a favorable prognosis. PMID:26852361

    Cytogenetic and molecular analyses of thyroid tumors have indicated that these neoplasms represent a good model for analyzing human epithelial cell multistep carcinogenesis. They comprise, in fact, a broad spectrum of lesions with different phenotypes and variable biological and clinical behavior. Molecular analysis has detected specific genetic alterations in the different types of thyroid tumors. In particular, the well-differentiated carcinomas of the papillary type are characterized by activation of the receptor tyrosine kinases (RTKs), RET and NTRK1 proto-oncogenes. Cytogenetic analysis of these tumors has contributed to defining the chromosomal mechanisms leading to RTK oncogenic activation. In the majority of cases, intrachromosomal inversions of chromosome 10 and chromosome 1 led to the formation of RET-derived and NTRK1-derived oncogenes, respectively. Interestingly, molecular analysis of these oncogenes revealed their nature of chimeric fusion proteins all sharing the tyrosine kinase (TK) domains of the respective proto-oncogenes. Moreover, the sequencing of the oncogenic rearrangements led to the identification of a breakpoint cluster region in both RTK proto-oncogenes. Exposure to ionizing radiation is associated with papillary carcinomas and RET activation has been suggested to be related to this event. Conversely, RAS point mutations are frequently observed in tumors with follicular histology and have been associated with metastatic dissemination. Iodide-deficient areas seem to provide a higher frequency of RAS positive follicular carcinomas. Finally, a high prevalence of TPS3 point mutations has been detected only in undifferentiated or anaplastic carcinomas and found to correlate inversely with 8CL2 expression. All of these findings are contributing to the definition of genetic and environmental factors relevant for the pathogenesis of thyroid tumors. Moreover, the characterization of specific genetic lesions could provide significant molecular

    Selection of novel molecular markers is an important goal of cancer genomics studies. The aim of our analysis was to apply the multivariate bioinformatical tools to rank the genes – potential markers of papillary thyroid cancer (PTC) according to their diagnostic usefulness. We also assessed the accuracy of benign/malignant classification, based on gene expression profiling, for PTC. We analyzed a 180-array dataset (90 HG-U95A and 90 HG-U133A oligonucleotide arrays), which included a collection of 57 PTCs, 61 benign thyroid tumors, and 62 apparently normal tissues. Gene selection was carried out by the support vector machines method with bootstrapping, which allowed us 1) ranking the genes that were most important for classification quality and appeared most frequently in the classifiers (bootstrap-based feature ranking, BBFR); 2) ranking the samples, and thus detecting cases that were most difficult to classify (bootstrap-based outlier detection). The accuracy of PTC diagnosis was 98.5% for a 20-gene classifier, its 95% confidence interval (CI) was 95.9–100%, with the lower limit of CI exceeding 95% already for five genes. Only 5 of 180 samples (2.8%) were misclassified in more than 10% of bootstrap iterations. We specified 43 genes which are most suitable as molecular markers of PTC, among them some well-known PTC markers (MET, fibronectin 1, dipeptidylpeptidase 4, or adenosine A1 receptor) and potential new ones (UDP-galactose-4-epimerase, cadherin 16, gap junction protein 3, sushi, nidogen, and EGF-like domains 1, inhibitor of DNA binding 3, RUNX1, leiomodin 1, F-box protein 9, and tripartite motif-containing 58). The highest ranking gene, metallophosphoesterase domain-containing protein 2, achieved 96.7% of the maximum BBFR score. PMID:17914110

    Anaplastic thyroid carcinoma is the least common but most lethal of thyroid cancers. All patients are classified as stage IV, with the primary lesion restricted to the thyroid gland in stage IVA; locoregional lymph nodes may exist in IVA/IVB; and IVC disease is defined by distant metastases. Prognosis is highly dependent on disease extent at presentation, and staging and establishing a plan of care must be accomplished quickly. Although almost all studies are biased due to their retrospective nature, the most important factors associated with longer survival are completeness of surgical resection (achievable in only a minority of patients) and high-dose (>40 Gy) external beam radiotherapy (preferably intensity modulated radiation therapy). Recent reports suggest that a multimodal approach (surgery, radiation, and chemotherapy) is beneficial. Given the high lethality even with apparent local disease, combination systemic therapy (cytotoxics and/or targeted agents) may improve outcomes in stage IVA/IVB patients. Newer, more effective drug combinations are urgently needed for IVC patients who want aggressive therapy. A candid discussion of the prognosis and management options, including palliative care/hospice, should be held with the patient and caregiver as soon as possible after diagnosis to clarify the patient's preference and expectations. Prospective multicenter clinical trials, incorporating molecular analyses of tumors, are required if we are to improve survival in anaplastic thyroid carcinoma. PMID:22869844

    From 1999 to 2007 we performed 104 surgical operations for thyroid malignancies. Over the same period, 312 patients underwent surgery for benign lesions of the thyroid gland. The patients were subdivided on the basis of age bracket and gender and the distribution of cancer and benign nodules was evaluated. Feasibility and diagnostic accuracy of ultrasonography, scintigraphy and fine needle aspiration cytology were also evaluated. The incidence of thyroid cancer was 25% in all patients. Patients aged < 30 years and > 71 had the highest rate of malignancies: 52% of patients under 30 years of age and 46% over 70 years. Males showed a higher incidence than females. The scintigraphic findings were an area of low uptake in 19 cases (47.5%), an irregular pattern in 12 patients (30%) and a high uptake in 9 cases (22.5%); in 3 of them (7.5%), cancer was in the contralateral lobe and in 2 cases (5%) the dimensions were 8 and 4 mm. Forty-three patients had a single hypoechoic nodule at ultrasonography (41.3%), 3 (3%) were found with hypoechoic nodules containing calcifications and 1 (0.9%) a single anechoic nodule. Fifty-six patients (53.9%) had multiple nodules and 1 (0.9%) was admitted for a latero-cervical lymph node. FNAC revealed 11 cases of fibronectin expression (14.4%): in particular, 3 patients (4%) had cancer in the contralateral lobe and 3 patients (4%) had tumours measuring less than 5 mm. Thyroid surgery is safe and the morbidity rate is about 2%. We observed only one lesion of recurrent nerve (0.5% of patients), temporary recurrent palsy in 2.8% of patients and transient hypocalcaemia in 6.7% of cases. PMID:19062491

    Anaplastic thyroid carcinoma (ATC) is the most aggressive form of thyroid cancer, and often derives from pre-existing well-differentiated tumors. Despite a relatively low prevalence, it accounts for a disproportionate number of thyroid cancer-related deaths, due to its resistance to any therapeutic approach. Here we describe the first mouse model of ATC, obtained by combining in the mouse thyroid follicular cells two molecular hallmarks of human ATC: activation of PI3K (via Pten deletion) and inactivation of p53. By 9 months of age, over 75% of the compound mutant mice develop aggressive, undifferentiated thyroid tumors that evolve from pre-existing follicular hyperplasia and carcinoma. These tumors display all the features of their human counterpart, including pleomorphism, epithelial-mesenchymal transition, aneuploidy, local invasion, and distant metastases. Expression profiling of the murine ATCs reveals a significant overlap with genes found deregulated in human ATC, including genes involved in mitosis control. Furthermore, similar to the human tumors, [Pten, p53]thyr−/− tumors and cells are highly glycolytic and remarkably sensitive to glycolysis inhibitors, which synergize with standard chemotherapy. Taken together, our results show that combined PI3K activation and p53 loss faithfully reproduce the development of thyroid anaplastic carcinomas, and provide a compelling rationale for targeting glycolysis to increase chemotherapy response in ATC patients.

Distant metastases are rare events at the onset of DTC. Among these presentations, metastasis to the liver is even more unusual. Only 11 cases of DTC with liver metastasis were previously reported in the literature. We present a 55-year-old male on Iodine-131 whole body scintigraphy showed intense uptake in thyroid bed, metastasis in both lungs and right lobe of the liver. Radioiodine concentration in liver metastases made him amenable to high-dose radioiodine therapy patient. PMID:26430327

    Hashimoto thyroiditis (HT) is an autoimmune disease, known to be the most common cause of hypothyroidism in nonendemic goitrous areas. It is usually characterized by symmetric, painless, and diffused but sometimes localized swelling of the thyroid gland with features of hypothyroidism. Papillary thyroid carcinoma (PTC), on the other hand, is the most common yet less aggressive form of thyroid cancer, especially in iodine-deficient areas. The coexistence of the two diseases is possible but not common. This case study reports a 50-year-old female with a 10-year history of a huge goiter, which was essentially symptom-free until about 3 months prior to presentation when the patient started complaining of neck pain, dysphagia, productive cough, and cold intolerance. Physical examination revealed focal cystic and tender area in the multinodular swelling and associated cervical lymphadenopathy on the left side of the neck. The serum thyroid stimulating hormone was high, sub-normal T3, and the T4 was low. The fine needle aspiration cytology yielded 10 ml of aspirate of pus admixed with altered blood which on microscopy showed a few suspicious follicular epithelial cells with open nuclei admixed with mainly neutrophil polymorphs, siderophages, and foam cells in a hemorrhagic background. The patient had an incision biopsy that showed areas displaying PTC and HT. PMID:26903704

    Disrupted thyroid hormone function evokes severe physiological consequences in the immature brain. In adulthood, although clinical reports document an effect of thyroid hormone status on mood and cognition, the molecular and cellular changes underlying these behavioural effects are poorly understood. More recently, the subtle effects of thyroid hormone on structural plasticity in the mature brain, in particular on adult hippocampal neurogenesis, have come to be appreciated. However, the specific stages of adult hippocampal progenitor development that are sensitive to thyroid hormone are not defined. Using nestin-green fluorescent protein reporter mice, we demonstrate that thyroid hormone mediates its effects on hippocampal neurogenesis by influencing Type 2b and Type 3 progenitors, although it does not alter proliferation of either the Type 1 quiescent progenitor or the Type 2a amplifying neural progenitor. Thyroid hormone increases the number of doublecortin (DCX)-positive Type 3 progenitors, and accelerates neuronal differentiation into both DCX-positive immature neurones and neuronal nuclei-positive granule cell neurones. Furthermore, we show that this increase in neuronal differentiation is accompanied by a significant induction of specific transcription factors involved in hippocampal progenitor differentiation. In vitro studies using the neurosphere assay support a direct effect of thyroid hormone on progenitor development because neurospheres treated with thyroid hormone are shifted to a more differentiated state. Taken together, our results indicate that thyroid hormone mediates its neurogenic effects via targeting Type 2b and Type 3 hippocampal progenitors, and suggests a role for proneural transcription factors in contributing to the effects of thyroid hormone on neuronal differentiation of adult hippocampal progenitors.

    Background. The aims of this study were to analyze the clinical characteristics of SPM in patients with well-differentiated thyroid cancer and to determine the long-term prognosis in patients with double malignancies. Materials and Methods. We retrospectively analyzed 2,864 patients with well-differentiated thyroid cancer and a mean age of 44.0 ± 14.4 years. Of these, 200 (7.0%) were diagnosed with SPM, 115 of which were diagnosed with metachronous SPM. Results. Of 2,864 patients, 163 (5.7%) patients died of thyroid cancer and 301 (10.5%) died of any cause by the end of the follow-up period. Multivariate analysis identified age, SPM, external radiotherapy, TNM stage, and postoperative serum Tg level to be factors independently associated with decreased survival. Of 200 patients with SPM, 74 (37.0%) died. In comparison to the anachronous and synchronous groups, the metachronous SPM group had a higher mean age; more advanced tumor, node, and metastasis stage; lower remission rate; higher postoperative radioactive iodide (131I) accumulated dose; a higher proportion of patients who underwent external radiotherapy; and higher thyroid cancer and total mortality rates. Conclusions. Patients with well-differentiated thyroid carcinoma and metachronous SPM had worse prognoses compared to patients without SPM. PMID:27118971

    Thyroid carcinoma (TC) is the most common endocrine malignancy, and its frequency is still rising. Papillary thyroid carcinoma (PTC) accounts for 80% of all TCs and usually is related to a very good prognosis. However, the standard therapeutic approaches are not always sufficient and disease progression is sometimes observed. These data highlight the limitation of our understanding of molecular mechanisms underlying tumorigenesis and how they vary between individual patients. Over the last 19 years mouse models of thyroid cancers have been developed in order to give answers to questions about their genetic background, relations of key molecular events with pathways fundamental for cancer, and many others. Among these models genetically engineered mice were of utmost importance regarding the input of knowledge about human tumorigenesis. In the present review the most significant mouse models of PTC are described with particular emphasis on BRAFV600E-induced ones, for the sake of its frequency in PTC, relation to factors of poor prognosis, and the fact that, since its identification, it became an attractive target in novel therapies. For the presented mouse models phenotype consequences of particular genetic alterations are described as well as the limitations of the used methods. (Endokrynol Pol 2016; 67 (2): 212-223).

    Trace elemental analysis was carried out in the biological samples of normal, adenoma and carcinoma thyroids using particle induced X-ray emission technique (PIXE). A 2 MeV proton beam was employed to excite the samples. The elements Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Sr, I, Hg and Pb were identified and their concentrations were estimated. The concentrations of the elements Ca, Cu, Zn, As, I and Hg are found to be much lower in carcinoma thyroid than those in the normal thyroid while the concentration of the elements K, Ti, V, Cr, Mn, Fe, Co and Sr in carcinoma thyroid are higher than the concentrations in normal thyroid. The lower and higher values of some of the elements in carcinoma thyroid may be attributed to some pathological factors.

    Introduction Intraoperative management of thyroid gland in laryngeal and hypopharyngeal cancer is controversial. Aim The objectives of this study were to determine the incidence of thyroid gland invasion in patients undergoing surgery for laryngeal or hypopharyngeal carcinoma, to assess predictive factors and to assess the prognosis in patients with and without thyroid gland invasion. Materials and Methods One hundred and thirty-three patients who underwent surgery for carcinoma larynx and hypopharynx from 2006 to 2010 were reviewed retrospectively. Surgical specimens were examined to determine the incidence of thyroid gland invasion and predictive factors were analysed. The recurrence rate and the survival in patients with and without thyroid gland invasion were also analysed. Results Out of the 133 patients with carcinoma larynx and hypopharynx who underwent surgery, histological thyroid gland invasion was observed in 28/133 (21%) patients. Significant relationship was found between histological thyroid gland invasion and preoperative evidence of thyroid cartilage erosion by CT scan and also when gross thyroid gland involvement observed during surgery. There is significant association between thyroid gland invasion when there is upper oesophageal or subglottic involvement. Conclusion After analysing the retrospective data from our study, we would like to suggest that thyroid gland need not be removed routinely in all laryngectomies, unless there is advanced disease with thyroid cartilage erosion and gross thyroid gland involvement or disease with significant subglottic or oesophageal involvement.

    The DICER1 gene encodes an endoribonuclease involved in the production of mature microRNAs which regulates gene expression through several mechanisms. Carriers of germline DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 syndrome. Pleuropulmonary blastoma is the most frequent lesion seen in this syndrome. Thyroid abnormalities are also a common finding, essentially concerning multinodular goiter. However, differentiated thyroid carcinoma is infrequently seen in such pedigrees. In addition to germline DICER1 mutations, specific somatic mutations have been identified in the DICER1 RNase IIIb catalytic domain in several tumor types, including ovarian Sertoli-Leydig cell tumors. We report two cases of differentiated thyroid carcinoma associated with ovarian Sertoli-Leydig cell tumor and with a heterozygous DICER1 gene mutation, occurring in two unrelated young girls without pleuropulmonary blastoma. Both thyroid carcinomas showed an E1813 mutation in exon 25 while the ovarian tumors harboured a somatic mutation in E1705 in exon 24 and a D1709 mutation in exon 25. Our observations confirm that the occurrence of an ovarian Sertoli-Leydig cell tumor with a thyroid carcinoma is highly suggestive of a DICER1 syndrome. We contend that the possibility of a relationship between sporadic thyroid carcinoma in young patients and somatic DICER1 gene mutation needs further investigation. PMID:26983701

    The incidence of thyroid cancer is increasing, especially papillary thyroid carcinoma (PTC), making it currently the fastest-growing cancer among women. Reasons for this increase remain unclear, but several risk factors including radiation exposure and improved detection techniques have been suggested. Recently, the induction of chromosomal fragile site breakage was found to result in the formation of RET/PTC1 rearrangements, a common cause of PTC. Chromosomal fragile sites are regions of the genome with a high susceptibility to forming DNA breaks and are often associated with cancer. Exposure to a variety of external agents can induce fragile site breakage, which may account for some of the observed increase in PTC. This paper discusses the role of fragile site breakage in PTC development, external fragile site-inducing agents that may be potential risk factors for PTC, and how these factors are especially targeting women.

    Ninety-one patients with histologically proven anaplastic carcinoma of the thyroid were referred to the Beatson Oncology Centre between 1961 and 1986. The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dysphagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

Tracheal incubation was performed safety by using percutaneous cardiopulmonary support. A subtotal thyroidectomy was performed by midsternotomy with cervical incision. The weight of the resected specimen was 340 g and the pathological diagnosis was follicular thyroid carcinoma. The postoperative course was uneventful and the patient suffered no hoarseness and dyspnea. PMID:18464485

    Papillary thyroid carcinoma (PTC) commonly metastasizes to cervical lymph nodes. Distant metastases are unusual with the lungs most frequently involved. Well-differentiated thyroid carcinoma very rarely presents with metastases to the spleen. This is the case of a 25-year-old man with a history of PTC (1.4 cm primary; no capsular invasion and negative lymph node metastases). One year after initial surgery, recurrent disease was found in multiple neck nodes by central neck dissection. Whole body scan (WBS) following a therapeutic ablation dose of 150 mCi I(131) revealed mediastinal metastases. Computerized axial tomography (CT) of the chest one year later showed no gross mediastinal or pulmonary disease. However, multiple large splenic lesions were incidentally noted. Evaluation by ultrasound (US) showed lesions to be solid echogenic masses without remarkable Doppler characteristics to suggest vascular tumors. US-guided percutaneous fine-needle aspiration biopsy (FNAB) of one lesion was nondiagnostic. After withdrawal from Levothyroxine, serum TSH was >100 mU/L with a thyroglobulin of 9.4 ng/mL and negative anti-thyroglobulin antibodies. Diagnostic WBS revealed faint splenic uptake but was otherwise unremarkable. Following treatment with 192 mCi I(131), WBS demonstrated increased activity in the mediastinum as well as in the spleen suggesting mediastinal and splenic metastases. Contrast CT of the abdomen showed multiple low-attenuated heterogeneously enhancing splenic masses, normal liver and no intra-abdominal lymphadenopathy. The largest mass (4.5 x 3.5 cm) was exophytic and in close proximity to the splenic capsule. Despite the serum thyroglobulin of only 9.4 ng/mL, the finding of I(131) accumulation within solid splenic masses led to a preoperative diagnosis of thyroid carcinoma metastases. To establish the diagnosis and to remove the risk for splenic rupture, a laparoscopic splenectomy was performed. Histopathologic analysis showed large littoral cell angiomas

    We present the second reported mammary analog secretory carcinoma (MASC) apparently arising in the thyroid and propose a potential close relationship to ETV6-NTRK3 fusion papillary thyroid carcinoma. The patient, a 36 year old woman, presented with a neck mass of 1 year's duration. Imaging studies showed a tumor involving most of the thyroid with enlarged regional lymph nodes. FNA biopsy yielded a diagnosis of "papillary thyroid carcinoma". Resection revealed a 4.5 cm infiltrative tumor. Final diagnosis was "papillary thyroid carcinoma (PTC) consistent with diffuse sclerosing variant" with positive lymph nodes (2+/4) and margins. Histologic features included mixed microcystic, solid, follicular and papillary architecture, prominent nucleoli, abundant nuclear grooves and rare nuclear pseudo-inclusions. Despite radioactive iodine, radiotherapy and multiagent chemotherapy, the patient progressed over 6 years with local recurrence and additional lymph node involvement finally developing widespread distant metastases. Prompted by the breast carcinoma-like histopathology of a metastasis, immunohistochemical staining was performed and revealed strong expression of GATA3 and mammaglobin with no reactivity for thyroglobulin or TTF-1. The original tumor was then tested and showed the same immunoprofile. RT-PCR confirmed the presence of an ETV6-NTRK3 fusion consistent with a diagnosis of MASC. Our patient's clinical, imaging and morphologic features remarkably mimicked papillary thyroid carcinoma. At the molecular level, the ETV6-NTRK3 fusion in this patient involved exons reported in the rare "papillary thyroid carcinoma" with this translocation. Given the immunophenotype of this case, it is possible that at least some ETV6-NTRK3 fusion positive PTC are actually MASC masquerading as papillary thyroid carcinoma. PMID:27075025

    Objective: Thyroid cancer constitutes approximately 1% of all cancers, approximately 90% of the endocrine malignancies, and is responsible for 0.4% of cancer-related deaths. Additional markers are required for the accurate diagnosis of thyroid malignancies. There is no marker that can accurately facilitate pre-operative benign-malignant differentiation of thyroid nodules. The present study aims to evaluate the diagnostic value of preoperative serum Galectin-3 levels in thyroid cancer and to avoid unnecessary aggressive interventions. Material and Methods: Sixty-four patients who were operated between May 2009 and April 2011 were included in this study prospectively. Patients with toxic nodules and those with malignancies detected in preoperative fine needle aspiration biopsies (FNAB) were excluded. Patients with thyroid nodules of >3 cm in ultrasonography or having suspicious cytological findings in their preoperative FNABs regardless of the nodule size were included. Patients were divided into 2 groups, “control”and “cancer,” according to the postoperative pathology results. Results: The control group included 50 and cancer group included 14 patients. The mean age of the control group was 44.84±13.17 (19–79), while it was 44.14±15.94 (25–72) in the cancer group. A statistically significant difference was found between Galectin-3 levels in the cancer and control groups (p<0.001). Conclusion: In the present study, serum Galectin-3 levels in patients with malignant nodules were statistically significant. PMID:26668525

    Hürthle cell carcinoma (HCC) is a variant of a follicular carcinoma with a tendency to higher frequency of metastases and a lower survival rate. However, intracavitary cardiac metastases from thyroid HCC are extremely rare. We describe the case of a 57-year-old female with thyroid HCC, 5 years after total thyroidectomy, who presented with dyspnea associated with hypoxia and hypotension. The computed tomography angiogram showed extensive pulmonary embolism and a 6-cm right atrial mass while the lower-extremity deep vein thrombosis studies were negative. This patient received a cardiac thrombectomy using cardiopulmonary bypass support. However, intraoperatively, we found out that the mass was from the mediastinum, directly extending into the heart and clearly unresectable since it effaced at least 1/3 of the right atrial wall. The core biopsy of the mass confirmed that it was metastatic poorly differentiated HCC of thyroidal origin. The patient eventually died of respiratory failure due to a massive pulmonary embolism. For cancer patients with unexplained dyspnea, cardiac metastases should be considered regardless of anticoagulation prophylaxis, especially when there is no deep vein thrombosis in the lower limbs. Early recognition of intracavitary cardiac metastases may help in providing prompt treatment and improving the prognosis. PMID:26078743

    Struma ovarii (SO) is a slow-growing ovarian neoplasm with thyroid tissue as its predominant component. It is an uncommon neoplasm, usually asymptomatic with an unknown risk of malignant transformation. Due to difficulties in assessing the rare biological nature and the discrepancies in the reported cases, a consensus on the appropriate treatment has not been definitively reached. A 50-year-old female was subjected to upper gut endoscopy which showed a 30-mm mass located in the gastric antrum, suggestive of mesenchimal tumor. Incidentally, a pelvic CT scan also documented a solid mass in the right adnexa, with morphological characteristics of ovarian neoplasm. The patient underwent gastrectomy, total hysterectomy, bilateral salpingo-oophorectomy with lymph node dissection, and omentectomy. Histology documented the presence of gastric cavernous angioma, and, in the right adnexa, foci of follicular thyroid-type carcinoma arising in SO with a well-differentiated neuroendocrine component.Here we report and discuss the clinical and morphological presentation of follicular thyroid-type carcinoma arising in SO. The neoplasm was discovered incidentally and had a favorable clinical outcome at 1-year follow-up. PMID:22613573

    Anaplastic thyroid carcinoma is an aggressive variant of thyroid cancer that in most cases arises from anaplastic transformation of terminally differentiated thyroid carcinomas. This process usually occurs in the thyroid or cervical lymph nodes. Anaplastic transformation in distant metastatic sites is exceedingly rare, only previously documented in a few case reports. We report a rare case of anaplastic transformation of papillary thyroid carcinoma within a large retroperitoneal metastasis in a 64-year-old male 30 years after the initial diagnosis. PMID:26351607

  20. FAP Associated Papillary Thyroid Carcinoma: A Peculiar Subtype of Familial Nonmedullary Thyroid Cancer

    2015-01-01

    Familial Nonmedullary Thyroid Carcinoma (FNMTC) makes up to 5–10% of all thyroid cancers, also including those FNMTC occurring as a minor component of familial cancer syndromes, such as Familial Adenomatous Polyposis (FAP). We give evidence that this extracolonic manifestation of FAP is determined by the same germline mutation of the APC gene responsible for colonic polyps and cancer but also shows some unusual features (F : M ratio = 80 : 1, absence of LOH for APC in the thyroid tumoral tissue, and indolent biological behaviour, despite frequent multicentricity and lymph nodal involvement), suggesting that the APC gene confers only a generic susceptibility to thyroid cancer, but perhaps other factors, namely, modifier genes, sex-related factors, or environmental factors, are also required for its phenotypic expression. This great variability is against the possibility of classifying all FNMTC as a single entity, not only with a unique or prevalent causative genetic factor, but also with a unique or common biological behavior and a commonly dismal prognosis. A new paradigm is also suggested that could be useful (1) for a proper classification of FAP associated PTC within the larger group of FNMTC and (2) for making inferences to sporadic carcinogenesis, based on the lesson from FAP.

    Adhesion of tumor cells to the extracellular matrix (ECM) is a crucial step for the development of metastatic disease and is mediated by specific integrin receptor molecules (IRM). The pattern of metastatic spread differs substantially among the various histotypes of thyroid cancer (TC). However, IRM have only occasionally been characterized in TC until now. IRM expression was investigated in 10 differentiated (FTC133, 236, 238, HTC, HTC TSHr, XTC, PTC4.0/4.2, TPC1, Kat5) and two anaplastic TC cell lines (ATC, C643, Hth74), primary cultures of normal thyroid tissue (Thy1,3), and thyroid cancer specimens (TCS). Expression of 16 IRM (beta1-4, beta7, alpha1-6, alphaV, alphaIIb, alphaL, alphaM, alphaX) and of four IRM heterodimers (alpha2beta1, alpha5beta1, alphaVbeta3, alphaVbeta5), was analyzed by fluorescent-activated cell sorter (FACS) and immunohistochemical staining. Thyroid tumor cell adhesion to ECM proteins and their IRM expression in response to thyrotropin (TSH) was assessed. Follicular TC cell lines presented high levels of integrins alpha2, alpha3, alpha5, beta1, beta3 and low levels of alpha1, whereas papillary lines expressed a heterogenous pattern of IRM, dominated by alpha5 and beta1. ATC mainly displayed integrins alpha2, alpha3, alpha5, alpha6, beta1 and low levels of alpha1, alpha4 and alphaV. Integrin heterodimers correlated with monomer expression. Evaluation of TCS largely confirmed these results with few exceptions, namely alpha4, alpha6, and beta3. The ability of TC cell lines to adhere to purified ECM proteins correlated with IRM expression. TSH induced TC cell adhesion in a dose-dependent fashion, despite an unchanged array of IRM expression or level of a particular IRM. Thyroid carcinoma cell lines of different histogenetic background display profoundly different patterns of IRM expression that appear to correlate with tumor aggressiveness. In vitro adhesion to ECM proteins and IRM expression concur. Finally, TSH-stimulated adhesion of

    We have presented a case of sporadic medullary carcinoma of the thyroid with documentation of localization of tracer {sup 131}I-MIBG within the primary neoplasm. A review of the nuclear medicine literature of localization techniques for MCT demonstrates that {sup 131}I-MIBG, while an excellent choice for diagnosis of pheochromocytoma and neuroblastoma, produces low yield and unpredictable concentration in other neural crest apudomas, including MCT. A low incidence of true-positive results with {sup 131}I-MIBG uptake and a high incidence of false-negative results make this radiopharmaceutical a suboptimal choice for diagnostic studies, but a potentially promising one as a therapeutic agent.33 references.

    Molecular etiology of thyroid cancers has been widely studied, and several molecular alterations have been identified mainly associated with follicular and papillary histotypes. However, the molecular bases of the complex pathogenesis of thyroid carcinomas remain poorly understood. HOX genes regulate normal embryonic development, cell differentiation and other critical processes in eukaryotic cell life. Several studies have shown that HOX genes play a role in neoplastic transformation of several human tissues. In particular, the genes belonging to HOX paralogous group 13 seem to hold a relevant role in both tumor development and progression. We have identified a significant prognostic role of HOX D13 in pancreatic cancer and we have recently showed the strong and progressive over-expression of HOX C13 in melanoma metastases and deregulation of HOX B13 expression in bladder cancers. In this study we have investigated, by immunohistochemisty and quantitative Real Time PCR, the HOX paralogous group 13 genes/proteins expression in thyroid cancer evolution and progression, also evaluating its ability to discriminate between main histotypes. Our results showed an aberrant expression, both at gene and protein level, of all members belonging to paralogous group 13 (HOX A13, HOX B13, HOX C13 and HOX D13) in adenoma, papillary and follicular thyroid cancers samples. The data suggest a potential role of HOX paralogous group 13 genes in pathogenesis and differential diagnosis of thyroid cancers. PMID:24189220

    The main nonmedullary form of thyroid cancer is papillary thyroid carcinoma (PTC) that accounts for 80–90% of all thyroid malignancies. Only 3–10% of PTC patients have a positive family history of PTC yet the familiality is one of the highest of all cancers as measured by case control studies. A handful of genes have been implicated accounting for a small fraction of this genetic predisposition. It was therefore of considerable interest that a mutation in the HABP2 gene was recently implicated in familial PTC. The present work was undertaken to examine the extent of HABP2 variant involvement in PTC. The HABP2 G534E variant (rs7080536) was genotyped in blood DNA from 179 PTC families (one affected individual per family), 1160 sporadic PTC cases and 1395 controls. RNA expression of HABP2 was tested by qPCR in RNA extracted from tumor and normal thyroid tissue from individuals that are homozygous wild-type or heterozygous for the variant. The variant was found to be present in 6.1% familial cases, 8.0% sporadic cases (2 individuals were homozygous for the variant) and 8.7% controls. The variant did not segregate with PTC in one large and 6 smaller families in which it occurred. In keeping with data from the literature and databases the expression of HABP2 was highest in the liver, much lower in 3 other tested tissues (breast, kidney, brain) but not found in thyroid. Given these results showing lack of any involvement we suggest that the putative role of variant HABP2 in PTC should be carefully scrutinized. PMID:26745718

    Tumor necrosis factor receptor-associated protein 1 (TRAP1) is a heat shock protein 90 (HSP90) molecular chaperone upregulated in several human malignancies and involved in protection from apoptosis and drug resistance, cell cycle progression, cell metabolism and quality control of specific client proteins. TRAP1 role in thyroid carcinoma (TC), still unaddressed at present, was investigated by analyzing its expression in a cohort of 86 human TCs and evaluating its involvement in cancer cell survival and proliferation in vitro Indeed, TRAP1 levels progressively increased from normal peritumoral thyroid gland, to papillary TCs (PTCs), follicular variants of PTCs (FV-PTCs) and poorly differentiated TCs (PDTCs). By contrast, anaplastic thyroid tumors exhibited a dual pattern, the majority being characterized by high TRAP1 levels, while a small subgroup completely negative. Consistently with a potential involvement of TRAP1 in thyroid carcinogenesis, TRAP1 silencing resulted in increased sensitivity to paclitaxel-induced apoptosis, inhibition of cell cycle progression and attenuation of ERK signaling. Noteworthy, the inhibition of TRAP1 ATPase activity by pharmacological agents resulted in attenuation of cell proliferation, inhibition of ERK signaling and reversion of drug resistance. These data suggest that TRAP1 inhibition may be regarded as potential strategy to target specific features of human TCs, i.e., cell proliferation and resistance to apoptosis. PMID:27422900

    The incidence of thyroid cancer is increasing rapidly. A large percentage of new cases identified fall into a low-risk category. As the incidence has increased, clinical experience has confirmed that the majority of patients will have excellent outcomes and that those at risk of doing badly can be reliably identified. Treatment for thyroid cancer is predominantly surgical. The decision about how aggressively this disease should be managed has remained controversial due to the excellent outcomes irrespective of the nature of surgical procedure chosen. This article reviews the developments in our understanding of the biology of thyroid cancer and the evidence that supports the approach to management. PMID:26918146

    Poorly differentiated tumors of the thyroid gland (PDTC) are generally characterized by a poor prognosis due to their resistance to available therapeutic approaches. The relative rarity of these tumors is a major obstacle to our understanding of the molecular mechanisms leading to tumor aggressiveness and drug resistance, and consequently to the development of novel therapies. By simultaneously activating Kras and deleting p53 in thyroid follicular cells, we have developed a novel mouse model that develops papillary thyroid cancer invariably progressing to PDTC. In several cases, tumors further progress to anaplastic carcinomas. The poorly differentiated tumors are morphologically and functionally similar to their human counterparts and depend on MEK/ERK signaling for proliferation. Using primary carcinomas as well as carcinoma-derived cell lines, we also demonstrate that these tumors are intrinsically resistant to apoptosis due to high levels of expression of the Bcl2 family members Bcl2a1 and Mcl1, and can be effectively targeted by Obatoclax, a small molecule pan-inhibitor of the Bcl2 family. Furthermore, we show that Bcl2 family inhibition synergizes with MEK inhibition as well as with doxorubicin in inducing cell death. Thus, our studies in a novel, relevant mouse model, uncover a promising druggable feature of aggressive thyroid cancers. PMID:25012986

    Recent advances in molecular diagnostics have led to significant insights into the genetic basis of thyroid tumorigenesis. Among the mutations commonly seen in thyroid cancers, the vast majority are associated with the mitogen-activated protein kinase pathway. B-Raf proto-oncogene (BRAF) mutations are the most common mutations observed in papillary thyroid cancers (PTCs), followed by RET/PTC rearrangements and RAS mutations, while follicular thyroid cancers are more likely to harbor RAS mutations or PAX8/peroxisome proliferator-activated receptor γ (PPARγ) rearrangements. Beyond these more common mutations, alterations in the telomerase reverse transcriptase (TERT) promoter have recently been associated with clinicopathologic features, disease prognosis, and tumorigenesis in thyroid cancer. While the mutations underlying thyroid tumorigenesis are well known, the frequency of these mutations is strongly associated with geography, with clear differences reported between Asian and Western countries. Of particular interest is the prevalence of BRAF mutations, with Korean patients exhibiting the highest rate of BRAF-associated thyroid cancers in the world. Here, we review the prevalence of each of the most common mutations in Asian and Western countries, and identify the characteristics of well-differentiated thyroid cancer in Asians. PMID:26435130

    We report a rare case of black thyroid accompanied by papillary carcinoma in a patient with an extended history of minocycline treatment. A 78-year-old man was referred to our outpatient clinic with swelling in his neck. He had been taking minocycline for the previous 2 years and 7 months to treat chronic perianal pyoderma. Neck ultrasonography and computed tomography demonstrated a 3.5 × 3.7 × 5.0-cm nodule in the left thyroid lobe, and fine-needle aspiration cytology identified it as a papillary carcinoma. The patient underwent a total thyroidectomy and neck dissection. During the procedure, a distinct black discoloration of the thyroid parenchyma was observed. Histopathology confirmed both the black thyroid and the papillary carcinoma. Based on the thyroid gland's discoloration and the history of minocycline use, the patient was diagnosed with minocycline-induced black thyroid. He was symptom-free 20 months after surgery.

    The rare reports of mucinous variant of follicular carcinoma of the thyroid gland have not provided enough evidence to support the recognition of these tumors as a distinct clinicopathologic entity or to understand their etiopathogenesis. We report the fourth case of mucinous variant of follicular carcinoma displaying a minimally invasive tumor with diffuse expression of thyroglobulin, TTF-1, CD56, PAX-8, cytokeratins 7 and 19, in the absence of monoclonal carcinoembryonic antigen (CEA), cytokeratin 20, chromogranin, HBME-1, P63 expression, and BRAF gene mutation, in a 51-year-old woman who is alive without signs of disease 13 months after total thyroidectomy, bilateral neck dissection, and radioactive iodine. Herein, fine-needle aspiration cytology disclosed "worrisome" cytologic features consisting of large epithelial cells arranged in clusters or singularly, with high nucleocytoplasmic ratio, nuclear grooves and evident nucleoli which were shared by those of mucin-producing papillary thyroid carcinoma. Therefore, knowledge of the cytological and histopathological spectrum of this lesion is important to avoid misdiagnosis. The morphologic clues leading to the correct diagnosis of mucinous variant of follicular neoplasm have been correlated with the data of the literature, and the differential diagnosis is briefly discussed.

    There have only been a few reports of thyroid-like follicular carcinoma of the kidney (TLFCK) to date. In the present study, two patients with TLFCK are reported. Patient 1 was a 65-year-old male exhibiting repeated hematuria and right back pain. No tumors were located in the patient's thyroid or lungs. The physical examination revealed percussion tenderness over the right kidney region was noticed. Enhanced computed tomography (CT) indicated a right renal pelvic carcinoma, for which the patient underwent a radical right nephrectomy. Patient 2 was a 59-year-old male with a mass in the right kidney, located during a health examination and who exhibited no obvious clinical symptoms. The patient was clinically diagnosed with right renal carcinoma, confirmed by an enhanced CT. The patient underwent a radical right nephrectomy. The clinical features, imaging results, pathology, immune phenotypes, treatment and prognosis were analyzed. The associated literature was also reviewed. The cut surface of each tumor showed gray-white material with a central solid area, including scattered gray-brown necrotic and gray hemorrhagic areas and small cystic cavities.

    Papillary carcinoma of the thyroid is the commonest type of thyroid cancer. Laryngeal infiltration from papillary thyroid carcinoma is extremely rare, with only a few cases of partial invasion described in the literature. We present a very unusual case of complete infiltration of both thyroid and cricoid cartilages from a neglected papillary thyroid carcinoma in a 59-year-old male. This sequel resulted from refusal of the patient to undergo treatment when initially diagnosed. An invasion to such an extent has not been described in the literature before, and in this case warranted a total laryngectomy followed by radioactive iodine. Prompt management of papillary carcinomas is crucial for avoiding such complications. Future guidelines should include management options for the patients who deny treatment initially. PMID:27458595

    The hybridisation of an Affymetrix HG_U95Av2 oligonucleotide array with RNAs extracted from six human thyroid carcinoma cell lines and a normal human thyroid primary cell culture led us to the identification of the UbcH10 gene that was upregulated by 150-fold in all of the carcinoma cell lines in comparison to the primary culture cells of human normal thyroid origin. Immunohistochemical studies performed on paraffin-embedded tissue sections showed abundant UbcH10 levels in thyroid anaplastic carcinoma samples, whereas no detectable UbcH10 expression was observed in normal thyroid tissues, in adenomas and goiters. Papillary and follicular carcinomas were only weakly positive. These results were further confirmed by RT–PCR and Western blot analyses. The block of UbcH10 protein synthesis induced by RNA interference significantly reduced the growth rate of thyroid carcinoma cell lines. Taken together, these results would indicate that UbcH10 overexpression is involved in thyroid cell proliferation, and may represent a marker of thyroid anaplastic carcinomas. PMID:16106252

    Introduction: Struma ovarii is an ovarian teratoma, represented in more than 50% by thyroid tissue. Five percent of struma ovarii cases have been proven to be malignant and, as in the thyroid gland, papillary thyroid carcinoma is the most common histotype arising in struma ovarii. Because of the unusual occurrence of this tumor, its management and follow-up after pelvic surgery is still controversial. Usually, total thyroidectomy followed by radioiodine treatment is the choice treatment in metastatic malignant struma ovarii, while these procedures are still controversial in non-metastatic thyroid cancer arising in struma ovarii. Case Presentation: We report a female with follicular variant of papillary thyroid carcinoma arising in struma ovarii. After pelvic surgery, thyroid morphofunctional examinations were performed and a single nodular lesion in the left lobe was discovered. The patient underwent total thyroidectomy and histological examination showed a papillary carcinoma. Radioiodine-ablation of residual thyroid tissue was performed and levothyroxine mildly-suppressive treatment was started. Conclusions: A more aggressive treatment should not be denied for malignant struma ovarii without any evidence, even when apparently confined into the ovary. However, in selected cases, aggressive treatment may be advisable to decrease the risk of recurrence and to allow an accurate follow-up. PMID:25745492

    O-linked N-acetylglucosamine (O-GlcNAc) glycosylation (O-GlcNAcylation), a dynamic post-translational modification of nuclear and cytoplasmic proteins, may have a critical role in the regulation of biological cell processes and human cancer. O-GlcNAcylation is dynamically regulated by O-GlcNAc transferase (OGT) and O-GlcNAc hydrolase (OGA). Accumulating evidence suggests that O-GlcNAcylation is involved in a variety of types of human cancer. However, the exact role of O-GlcNAcylation in tumor pathogenesis or progression remains to be established. Computed tomography scans of patients with anaplastic thyroid carcinoma (ATC) reveal a rapid growth rate and invasion. The present study demonstrated that O-GlcNAcylation accelerates the progression of ATC. The global O-GlcNAc level of intracellular proteins was increased by overexpression of OGT or downregulation of OGA activity with the specific inhibitor Thiamet-G. By contrast, the global O-GlcNAc level was decreased by silencing of OGT. MTT assay indicated that O-GlcNAcylation significantly promotes cell proliferation. Furthermore, O-GlcNAcylation enhanced cellular biological functions, such as colony formation ability, migration and invasion, of ATC cells in vitro. The findings of the present study suggest that O-GlcNAcylation is associated with malignant properties of thyroid cancer, and may be a potential target for the diagnosis and treatment of thyroid cancer.

    Thyroid carcinoma presenting as a hyperfunctioning thyroid nodule is rare. A further complexity is added when interpretation of the histopathology itself is not straightforward. We describe a case of a 16-year-old girl presenting with clinical and biochemical evidence of thyrotoxicosis, and a 4 cm thyroid mass. An ultrasound and thyroid uptake scan demonstrated a toxic adenoma. Owing to the nodule size, fine needle aspiration of the thyroid adenoma was performed, which showed findings consistent with toxic adenoma. However, in view of the size of the nodule, a hemithyroidectomy was performed. Histological examination of the thyroid revealed a follicular variant of papillary carcinoma of the thyroid, and the patient underwent completion thyroidectomy. We report on the case and briefly review the available literature relating to the diagnostic challenge of this presentation. PMID:25948842

    TT cell line is the best known stabilized cell line derived from the human medullary thyroid carcinoma. The ultrastructural characteristics of these cells include well developed rough endoplasmic reticulum, a prominent Golgi apparatus and a considerable number of secretory granules. Numerous hormones were immunocytochemically demonstrated in TT cells of which calcitonin and calcitonin gene-related peptide (CGRP) are the products of the same gene but an alternative RNA processing. TT cells were found to produce some other hormones as well, namely ACTH, neurotensin, enkephalin, PTHrP, gastrin-releasing peptide (GRP), serotonin but also functional proteins of the chromogranin group, synaptophysin, NSE, calbindin and tyrosine hydroxylase. Some marker proteins have been detected in the cytosol (CEA) and in the cytoskeleton (alpha-tubulin, cytokeratin). The influence of numerous factors on the secretory activity of these cells has been demonstrated so far, including effects of 1,25-dihydroxycholecalciferol, glucocorticoids, sex steroids, cAMP, gastrin-releasing peptide, sodium butyrate, phorbol esters, ionomycin and forskolin. The investigators performed on the TT cell line demonstrate that this is the most reliable model system for the human parafollicular cells developed so far, in comparison to other cell lines derived from the medullary carcinoma of the thyroid.

    Monoclonal antibody (MAb) JT-95 was produced by immunization of mice with membrane fractions of a human thyroid carcinoma. Immuno-histochemical staining has demonstrated that the antigen recognized by JT-95 is strongly expressed in 95 (95%) of 100 cases of papillary carcinomas and in 3 (75%) of 4 cases of follicular carcinomas. In benign diseases of the thyroid gland, MAb JT-95 reacted with 0 (0%) of 39 adenomas, 1 (4%) of 21 adenomatous goiters, 0 (0%) of 8 hyperthyroidism specimens, and 3 (38%) of 8 chronic thyroiditis specimens. The antigen detected by MAb JT-95 has an apparent Mr 250,000 in thyroid carcinomas. Moreover, circulating antigen in thyroid carcinoma patients was detected by MAb JT-95 in an ELISA and in Western blotting. The circulating antigen has a Mr 105,000. MAb JT-95 conjugated with (131) I was administrated to nude mice bearing a human thyroid carcinoma. JT-95 131I accumulation at the transplanted tumor was visualized by autoradiography with 2.68-14.75-fold higher levels detected at the xenograft compared to that for normal organs. Based on these data, MAb JT-95 may be useful in the diagnosis detection and therapy of thyroid carcinoma. PMID:8620498

    Although fine-needle aspiration biopsy (FNAB) is a useful tool for diagnosing thyroid carcinoma, there are some risks of complications. In this study, we investigated tumor implantation by FNAB of papillary carcinoma. We compared the characteristics of the main tumors and implanted tumors of patients showing FNAB implantations. Between 1990 and 2002, 4912 patients underwent FNAB and were diagnosed as having papillary carcinoma. We encountered 7 cases of needle tract implantation, which account only for 0.14%. We reviewed these 7 cases as well as 3 other patients who underwent FNAB in other hospitals. The intervals between FNAB and detection of the implanted tumor ranged from 2 to 131 months. For these 10 patients, the main tumors in 6 were diagnosed as poorly differentiated carcinoma, and 7 showed extrathyroid extension. Five showed the development of implanted tumor after comparatively shorter intervals (2-68 months), and we classified these as the short interval group. The remaining 5 were classified as the long interval group, because tumor development occurred after 87-131 months. All 5 cases in the short interval group involved preoperatively detectable lymph node metastasis; those in the long interval group did not. The MIB-1 labeling index of the implanted tumor was high in 4 cases in the short interval group, but it was low in all cases in the long interval group. The implanted tumors could be surgically removed without recurrence at the focal sites. These findings indicate that, although high growth activity in the metastatic lesions may be a risk factor of FNAB, inducing the growth of implanted tumors along the needle tract within a short interval after the procedure, FNAB remains the most useful technique for diagnosing thyroid carcinoma. The incidence of implantation was low, and when it did occur, the tumors could be surgically removed without recurrence. PMID:16311845

    Activating germ-line point mutations in the RET receptor are responsible for multiple endocrine neoplasia type 2-associated medullary thyroid carcinoma (MTC), whereas somatic RET rearrangements are prevalent in papillary thyroid carcinomas (PTCs). Some rare kindreds, carrying point mutations in RET, are affected by both cancer types, suggesting that, under specific circumstances, point mutations in RET can drive the generation of PTC. Here we describe a family whose siblings, affected by both PTC and MTC, carried a germ-line point mutation in the RET extracellular domain, converting cysteine 634 into serine. We tested on thyroid follicular cells the transforming activity of RET(C634S), RET(K603Q), another mutant identified in a kindred with both PTC and MTC, RET(C634R) a commonly isolated allele in MEN2A, RET(M918T) responsible for MEN2B and also identified in kindreds with both PTC and MTC, and RET/PTC1 the rearranged oncogene that characterizes bona fide PTC in patients without MTC. We show that the various RET point mutants, but not wild-type RET, scored constitutive kinase activity and exerted mitogenic effects for thyroid PC Cl 3 cells, albeit at significantly lower levels compared to RET/PTC1. The low mitogenic activity of RET point mutants paralleled their reduced kinase activity compared to RET/PTC. Furthermore, RET point mutants maintained a protein domain, the intracellular juxtamembrane domain, that exerted negative effects on the mitogenic activity. In conclusion, RET point mutants can behave as dominant oncogenes for thyroid follicular cells. Their transforming activity, however, is rather modest, providing a possible explanation for the rare association of MTC with PTC. PMID:15277225

    It has been reported that papillary thyroid carcinoma (PTC) with chronic lymphocytic thyroiditis (CLT) is less associated with extrathyroidal extension (ETE), advanced tumor stage and lymph node (LN) metastasis. Other studies have suggested that concurrent CLT could antagonize PTC progression, even in BRAF-positive patients. Since the clinical significance of the BRAF mutation has been particularly associated with conventional PTC, the purpose of this study was to determine the clinical significance of CLT according to BRAF mutation status in conventional PTC patients. We retrospectively reviewed the medical records of 3332 conventional PTC patients who underwent total thyroidectomy with bilateral central neck dissection at the Thyroid Cancer Center of Samsung Medical Center between January 2008 and June 2015. In this study, the prevalence of BRAF mutation was significantly less frequent in conventional PTC patients with CLT (76.9% vs 86.6%). CLT was an independent predictor for low prevalence of ETE in both BRAF-negative (OR=0.662, P=0.023) and BRAF-positive (OR=0.817, P=0.027) conventional PTC patients. In addition, CLT was an independent predictor for low prevalence of CLNM in both BRAF-negative (OR=0.675, P=0.044) and BRAF-positive (OR=0.817, P=0.030) conventional PTC patients. In conclusion, BRAF mutation was significantly less frequent in conventional PTC patients with CLT. However, CLT was an independent predictor for less aggressiveness in conventional PTC patients regardless of BRAF mutation status. PMID:26598713

    Background Whereas 40 % to 70 % of papillary thyroid carcinomas (PTCs) are characterized by a BRAF mutation (BRAFmut), unified biomarkers for the genetically heterogeneous group of BRAF wild type (BRAFwt) PTCs are not established yet. Using state-of-the-art technology we compared RNA expression profiles between conventional BRAFwt and BRAFmut PTCs. Methods Microarrays covering 36,079 reference sequences were used to generate whole transcript expression profiles in 11 BRAFwt PTCs including five micro PTCs, 14 BRAFmut PTCs, and 7 normal thyroid specimens. A p-value with a false discovery rate (FDR) < 0.05 and a fold change > 2 were used as a threshold of significance for differential expression. Network and pathway utilities were employed to interpret significance of expression data. BRAF mutational status was established by direct sequencing the hotspot region of exon 15. Results We identified 237 annotated genes that were significantly differentially expressed between BRAFwt and BRAFmut PTCs. Of these, 110 genes were down- and 127 were upregulated in BRAFwt compared to BRAFmut PTCs. A number of molecules involved in thyroid hormone metabolism including thyroid peroxidase (TPO) were differentially expressed between both groups. Among cancer-associated molecules were ERBB3 that was downregulated and ERBB4 that was upregulated in BRAFwt PTCs. Two microRNAs were significantly differentially expressed of which miR492 bears predicted functions relevant to thyroid-specific molecules. The protein kinase A (PKA) and the G protein-coupled receptor pathways were identified as significantly related signaling cascades to the gene set of 237 genes. Furthermore, a network of interacting molecules was predicted on basis of the differentially expressed gene set. Conclusions The expression study focusing on affected genes that are differentially expressed between BRAFwt and BRAFmut conventional PTCs identified a number of molecules which are connected in a network and affect

    Napsin A and thyroid transcription factor-1 (TTF-1) are useful biomarkers for differentiating lung adenocarcinoma from squamous cell carcinoma and also for differentiating primary lung adenocarcinoma from metastatic lung carcinoma. Pair-boxed 8 (PAX8) can help in distinguishing primary lung carcinoma from metastatic carcinomas and help to determine the primary sites of metastatic carcinomas. Immunohistochemistry for Napsin A, TTF-1, and PAX8 were performed on 193 cases of carcinoma: 50 primary lung carcinoma and 143 carcinomas from other sites. Napsin A and TTF-1 were positive in 54, 52 % of lung carcinomas cases, respectively. While in adenocarcinoma cases, their expressions were 86.7 and 83.3 %, respectively. PAX8 was negative in all lung carcinomas. TTF-1 and PAX8 were positive in 93.3 and 96.7 % of thyroid carcinoma cases and in 87.5 and 93.8 % of papillary carcinoma respectively, and both were positive in 100 % of follicular carcinoma. Napsin A was negative in all thyroid carcinomas. Napsin A and PAX8 were positive in 50 and 93.3 % of renal carcinoma cases and in 81.8 and 100 % of papillary carcinoma, 38.5 and 92.3 % of clear cell carcinoma, and 16.7 and 83.3 % of chromophobe carcinoma respectively. TTF-1 was negative in all renal carcinomas. PAX8 was positive in 80 % of ovarian carcinoma cases; 100 and 60 % of serous mucinous carcinomas, respectively. It was also positive in 100 % of endometrial carcinoma. Napsin A and TTF-1 were negative in both ovarian and endometrial carcinomas. Our data demonstrated that combined use of Napsin A, TTF-1, and PAX8 may help in differentiating between primary lung adenocarcinoma and metastatic lung carcinomas. PMID:26427663

    Incidental papillary carcinoma of the thyroid in patients treated surgically for benign thyroid diseases including Graves' disease is a known phenomenon. However, the management of these patients remains an issue of concern and controversy for those who care for them. We report a case of metastatic papillary carcinoma of the thyroid in a patient previously treated for Graves' disease. The subject of this presentation is a 50-year-old lady who was diagnosed with Graves' disease at the age of 29, for which she had a subtotal thyroidectomy following failure of medical and radioactive iodine treatment. Three years later, the patient was referred to our nuclear medicine department with a clinical diagnosis of suspected metastatic lymph nodes presumably from a thyroid malignancy.She had an 123I diagnostic whole body scan that showed 123I avid areas in the thyroid bed as well as left cervical lymph nodes, which later turned out to be metastatic papillary carcinoma of the thyroid on histology. She was treated with therapeutic doses of 131I. Follow-up radioactive iodine scans and serum thyroglobulin assays showed no evidence of malignant thyroid tissue. The occurrence of papillary carcinoma of the thyroid after a subtotal thyroidectomy for Graves' disease is hereby reported. The need for vigilance and regular follow-up in patients who receive all forms of treatment for benign thyroid diseases is emphasized. PMID:24705115

    We describe 2 adult women (72 and 54 years), 1 with a low-grade noninvasive papillary urothelial carcinoma of the renal pelvis, who 14 years later developed a papillary carcinoma in 1 thyroid lobe and a medullary carcinoma in the contralateral lobe. Both neoplasms were similar in size and appeared symmetrical. Despite its small size, the medullary carcinoma metastasized in multiple cervical lymph nodes. The second patient had a high-grade invasive papillary urothelial carcinoma of the renal pelvis that infiltrated the renal parenchyma and metastasized in one of the lungs. Five months later, a papillary carcinoma was discovered in the thyroid gland. The 2 papillary thyroid carcinomas were of the follicular variant. Adjacent to 1 papillary carcinoma, there was a dominant nodule of a colloid and adenomatous goiter. The medullary carcinoma contained stromal amyloid and was immunoreactive for calcitonin and carcinoembryonic antigen. There was no C-cell hyperplasia (medullary carcinoma in situ). The 2 patients are alive, 1 is living with pulmonary metastasis from the high-grade urothelial carcinoma. Twelve cases of this neoplastic association were registered in the Survey, Epidemiology, and End Results Program from 1980 to 2009. We believe that the combination of these unusual neoplasms in the same patient may represent a new sporadic neoplastic syndrome. PMID:25175810

    Background Follicular variant of papillary thyroid carcinoma (FVPTC) and follicular adenoma (FA) are histologically closely related tumors and differential diagnosis remains challenging. RNA expression profiling is an established method to unravel molecular mechanisms underlying the histopathology of diseases. Methods BRAF mutational status was established by direct sequencing the hotspot region of exon 15 in six FVPTCs and seven FAs. Whole-transcript arrays were employed to generate expression profiles in six FVPTCs, seven FAs and seven normal thyroid tissue samples. The threshold of significance for differential expression on the gene and exon level was a p-value with a false discovery rate (FDR) < 0.05 and a fold change cutoff > 2. Two dimensional average linkage hierarchical clustering was generated using differentially expressed genes. Network, pathway, and alternative splicing utilities were employed to interpret significance of expression data on the gene and exon level. Results Expression profiling in FVPTCs and FAs, all of which were negative for a BRAF mutation, revealed 55 transcripts that were significantly differentially expressed, 40 of which were upregulated and 15 downregulated in FVPTCs vs. FAs. Amongst the most significantly upregulated genes in FVPTCs were GABA B receptor, 2 (GABBR2), neuronal cell adhesion molecule (NRCAM), extracellular matrix protein 1 (ECM1), heparan sulfate 6-O-sulfotransferase 2 (HS6ST2), and retinoid X receptor, gamma (RXRG). The most significantly downregulated genes in FVPTCs included interaction protein for cytohesin exchange factors 1 (IPCEF1), G protein-coupled receptor 155 (GPR155), Purkinje cell protein 4 (PCP4), chondroitin sulfate N-acetylgalactosaminyltransferase 1 (CSGALNACT1), and glutamate receptor interacting protein 1 (GRIP1). Alternative splicing analysis detected 87 genes, 52 of which were also included in the list of 55 differentially expressed genes. Network analysis demonstrated multiple interactions

    Background: Previous guidelines for the management of thyroid nodules and cancers were geared toward adults. Compared with thyroid neoplasms in adults, however, those in the pediatric population exhibit differences in pathophysiology, clinical presentation, and long-term outcomes. Furthermore, therapy that may be recommended for an adult may not be appropriate for a child who is at low risk for death but at higher risk for long-term harm from overly aggressive treatment. For these reasons, unique guidelines for children and adolescents with thyroid tumors are needed. Methods: A task force commissioned by the American Thyroid Association (ATA) developed a series of clinically relevant questions pertaining to the management of children with thyroid nodules and differentiated thyroid cancer (DTC). Using an extensive literature search, primarily focused on studies that included subjects ≤18 years of age, the task force identified and reviewed relevant articles through April 2014. Recommendations were made based upon scientific evidence and expert opinion and were graded using a modified schema from the United States Preventive Services Task Force. Results: These inaugural guidelines provide recommendations for the evaluation and management of thyroid nodules in children and adolescents, including the role and interpretation of ultrasound, fine-needle aspiration cytology, and the management of benign nodules. Recommendations for the evaluation, treatment, and follow-up of children and adolescents with DTC are outlined and include preoperative staging, surgical management, postoperative staging, the role of radioactive iodine therapy, and goals for thyrotropin suppression. Management algorithms are proposed and separate recommendations for papillary and follicular thyroid cancers are provided. Conclusions: In response to our charge as an independent task force appointed by the ATA, we developed recommendations based on scientific evidence and expert opinion for the

    The aim of the present study was to identify potential therapeutic targets for papillary thyroid carcinoma (PTC) and to investigate the possible mechanism underlying this disease. The gene expression profile, GSE53157, was downloaded from the Gene Expression Omnibus database. Only 10 chips, including 3 specimens of normal thyroid tissues and 7 specimens of well-differentiated thyroid carcinomas, were analyzed in the present study. Differentially-expressed genes (DEGs) between PTC patients and normal individuals were identified. Next, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses of DEGs were performed. Modules in the protein-protein interaction (PPI) network were identified. Significant target genes were selected from the microRNA (miRNA) regulatory network. Furthermore, the integrated network was constructed with the miRNA regulatory and PPI network modules, and key target genes were screened. A total of 668 DEGs were identified. Modules M1, M2 and M3 were identified from the PPI network. From the modules, DEGs of cyclin-dependent kinase inhibitor 1A, S100 calcium binding protein A6 (S100A6), dual specificity phosphatase 5, keratin 19, met proto-oncogene (MET) and lectin galactoside-binding soluble 3 were included in the Malacards database. In the miRNA regulatory and integrated networks, genes of cyclin-dependent kinase inhibitor 1C (CDKN1C), peroxisome proliferator-activated receptor γ, aryl hydrocarbon receptor, basic helix-loop-helix family, member e40 and reticulon 1 were the key target genes. S100A6, MET and CDKN1C may exhibit key roles in the progression and development of PTC, and may be used as specific therapeutic targets in the treatment of PTC. However, further experiments are required to confirm these results. PMID:26870166

    The recent increase in the detection of papillary thyroid carcinoma (PTC) has been influenced by the finding of incidental tumours. To this group, carcinomas measuring less than 1 cm (the so-called microcarcinomas) as well as those above 1 cm belong. Analyzing a case series from our own experience, this paper focuses on the current pre-operative diagnostic challenges that can lead to PTC incidental discovery. For this retrospective study, 287 patients with a PTC diagnosis were selected. For each, the following variables were analysed: sex, age, ultrasound (US) appearance, number of thyroid nodules, PTC size, PTC variants and presence of other associated pathology. Pre-operative fine needle aspiration (FNA) results were classified according to the five-tiered SIAPEC system. For 281 patients, the US-guided FNA results were available. Cytohistological correlation was evaluated in terms of FNA sensitivity and false negative rate. An incidental PTC was found in 45.2 % of patients. The majority of these were due to unsuccessful US detection of malignant nodules (103 cases); incorrect cytological diagnosis was responsible for the other 24 cases. The most powerful clinical confounding factors were: multinodular background versus single nodule presentations (p < 0.001) and histotype (follicular vs conventional variant, p < 0.05). Of course, tumour size remains a strongly influential feature on pre-operative diagnosis, with greater difficulties arising for carcinomas <5 mm. Moreover, FNA sensitivity was lower also in large PTCs (>2 cm) due to tumour heterogeneity. Although with limitations related to the tumour's intrinsic features and the thyroid background, US-guided FNA, especially if performed by a dedicated multidisciplinary team, is a powerful diagnostic tool for detecting malignant thyroid nodules. To the state of the art, we propose a practical clinical-pathological cut-off for this procedure, setting it at 5 mm. PMID:24997780

  10. RET/PTC Translocations and Clinico-Pathological Features in Human Papillary Thyroid Carcinoma

    Thyroid carcinoma is the most frequent endocrine cancer accounting for 5–10% of thyroid nodules. Papillary histotype (PTC) is the most prevalent form accounting for 80% of all thyroid carcinoma. Although much is known about its epidemiology, pathogenesis, clinical, and biological behavior, the only documented risk factor for PTC is the ionizing radiation exposure. Rearrangements of the Rearranged during Transfection (RET) proto-oncogene are found in PTC and have been shown to play a pathogenic role. The first RET rearrangement, named RET/PTC, was discovered in 1987. This rearrangement constitutively activates the transcription of the RET tyrosine-kinase domain in follicular cell, thus triggering the signaling along the MAPK pathway and an uncontrolled proliferation. Up to now, 13 different types of RET/PTC rearrangements have been reported but the two most common are RET/PTC1 and RET/PTC3. Ionizing radiations are responsible for the generation of RET/PTC rearrangements, as supported by in vitro studies and by the evidence that RET/PTC, and particularly RET/PTC3, are highly prevalent in radiation induced PTC. However, many thyroid tumors without any history of radiation exposure harbor similar RET rearrangements. The overall prevalence of RET/PTC rearrangements varies from 20 to 70% of PTCs and they are more frequent in childhood than in adulthood thyroid cancer. Controversial data have been reported on the relationship between RET/PTC rearrangements and the PTC prognosis. RET/PTC3 is usually associated with a more aggressive phenotype and in particular with a greater tumor size, the solid variant, and a more advanced stage at diagnosis which are all poor prognostic factors. In contrast, RET/PTC1 rearrangement does not correlate with any clinical–pathological characteristics of PTC. Moreover, the RET protein and mRNA expression level did not show any correlation with the outcome of patients with PTC and no correlation between RET/PTC rearrangements and the

    The thyroid imaging reporting and data system (TIRADS) and Bethesda system for reporting thyroid cytopathology (BSRTC) have been used for interpretation of ultrasound and fine-needle aspiration cytology (FNAC) results of thyroid nodules. BRAFV600E mutation analysis is a molecular tool in diagnosing thyroid carcinoma. Our objective was to compare the diagnostic value of these methods in differentiating high-risk thyroid nodules. Total 220 patients with high-risk thyroid nodules were recruited in this prospective study. They all underwent ultrasound, FNAC and BRAFV600E mutation analysis. The sensitivity and specificity of TIRADS were 73.1% and 88.4%. BSRTC had higher specificity (97.7%) and similar sensitivity (77.6%) compared with TIRADS. The sensitivity and specificity of BRAFV600E mutation (85.1%, 100%) were the highest. The combination of BSRTC and BRAFV600E mutation analysis significantly increased the efficiency, with 97.8% sensitivity, 97.7% specificity. In patients with BSRTC I-III, the mutation rate of BRAFV600E was 64.5% in nodules with TIRADS 4B compared with 8.4% in nodules with TIRADS 3 or 4A (P < 0.001). Our study indicated that combination of BSRTC and BRAFV600E mutation analysis bears a great value in differentiating high-risk thyroid nodules. The TIRADS is useful in selecting high-risk patients for FNAB and patients with BSRTC I-III for BRAFV600E mutation analysis. PMID:26597052

    The objective of this study was to determine the incidence of thyroid gland invasion in laryngeal and hypopharyngeal squamous cell carcinoma; and the association between clinicopathological parameters and thyroid gland invasion. Medical records of 75 patients with laryngeal and hypopharyngeal squamous cell carcinoma who underwent total laryngectomy with thyroidectomy were reviewed, retrospectively. Preoperative computed tomography scans, clinical and operative findings, and histopathological data of the specimens were evaluated. There were 73 male and two female patients with an age range of 41-88 years (mean 60.4 years). Hemithyroidectomy was performed in 62 (82.7 %) and total thyroidectomy was performed in 13 patients (17.3 %). Four patients had histopathologically proven thyroid gland invasion (5.3 %). In three patients, thyroid gland involvement was by means of direct invasion. Thyroid gland invasion was significantly correlated with thyroid cartilage invasion. Therefore, prophylactic thyroidectomy should not be a part of the treatment policy for these tumors. PMID:26547312

    Background/Objectives Thyroid hormone receptors are present on brown adipose tissue (BAT), indicating a role for thyroid hormone in the regulation of BAT activation. The objective of this study was to examine the effect of thyroid hormone withdrawal followed by thyroid hormone in TSH-suppressive dosages, on energy expenditure and brown adipose tissue activity. Subjects/Methods This study was a longitudinal study in an academic center, with a follow-up period of 6 months. Ten patients with well-differentiated thyroid carcinoma eligible for surgical treatment and subsequent radioactive iodine ablation therapy were studied in a hypothyroid state after thyroidectomy and in a subclinical hyperthyroid state (TSH-suppression according to treatment protocol). Paired two-tailed t-tests and linear regression analyses were used. Results Basal metabolic rate (BMR) was significantly higher after treatment with synthetic thyroid hormone (levothyroxine) than in the hypothyroid state (BMR 3.8 ± 0.5 kJ/min versus 4.4 ± 0.6 kJ/min, P = 0.012), and non-shivering thermogenesis (NST) significantly increased from 15 ± 10% to 25 ± 6% (P = 0.009). Mean BAT activity was significantly higher in the subclinical hyperthyroid state than in the hypothyroid state (BAT standard uptake value (SUVMean) 4.0 ± 2.9 versus 2.4 ± 1.8, P = 0.039). Conclusions Our study shows that higher levels of thyroid hormone are associated with a higher level of cold-activated BAT. Trial Registration ClinicalTrials.gov NCT02499471 PMID:26784028

    We report the results of ultrasound screening of the thyroid gland in 3,051 Belarus children 4-14 years of age exposed to radioactive fallout due to the Chernobyl accident. Screening was performed in 1990, 1993 and 1998. The study demonstrated that with time the prevalence of thyroid nodules in this contaminated region increased from 1.2% to 3.5%, mostly due to pathologically verified nodular goiter and non-verified small solid nodules and cysts. In contrast, the prevalence of thyroid carcinoma decreased from 0.6% in 1990 to 0.3% in 1993. We found 15 patients with carcinoma. On analysis of the ultrasound pattern of all carcinomas, we observed nodular and diffuse variants. Thus, we can conclude that systematic ultrasound screening is useful for the early detection of thyroid carcinoma in the population of Belarus exposed to radiation due to the Chernobyl accident.

    Somatic gene copy number variation contributes to tumor progression. Using comparative genomic hybridization (CGH) array, the presence of genomic imbalances was evaluated in a series of 27 papillary thyroid carcinomas (PTCs). To detect only somatic imbalances, for each sample, the reference DNA was from normal thyroid tissue of the same patient. The presence of the BRAF V600E mutation was also evaluated. Both amplifications and deletions showed an uneven distribution along the entire PTC cohort; amplifications were more frequent than deletions (mean values of 17.5 and 7.2, respectively). Number of aberration events was not even among samples, the majority of them occurring only in a small fraction of PTCs. Most frequent amplifications were detected at regions 2q35, 4q26, and 4q34.1, containing FN1, PDE5A, and GALNTL6 genes, respectively. Most frequent deletions occurred at regions 6q25.2, containing OPMR1 and IPCEF1 genes and 7q14.2, containing AOAH and ELMO1 genes. Amplification of FN1 and PDE5A genomic regions was confirmed by quantitative PCR. Frequency of amplifications and deletions was in relationship with clinical features and BRAF mutation status of tumor. In fact, according to the American Joint Committee on Cancer stage and American Thyroid Association (ATA) risk classification, amplifications are more frequent in higher risk samples, while deletions tend to prevail in the lower risk tumors. Analysis of single aberrations according to the ATA risk grouping shows that amplifications containing PDE5A, GALNTL6, DHRS3, and DOCK9 genes are significantly more frequent in the intermediate/high risk group than in the low risk group. Thus, our data would indicate that analysis of somatic genome aberrations by CGH array can be useful to identify additional prognostic variables. PMID:25863487

    Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma, and our understanding of its pathogenesis is incomplete. To elucidate the mechanisms underlying such progression and identify novel diagnostic markers, we aimed to discover the underlying gene associated with PTC. Integrated analysis of microarray datasets was performed to identify differentially expressed genes (DEGs) between PTCs and normal tissues. GO enrichment analysis and KEGG pathway enrichment analysis were then performed to uncover the functions of DEGs. Furthermore, the protein-protein interaction (PPI) network of DEGs was constructed. Five GEO datasets were obtained. Totally, 154 DEGs across the studies were identified, including 26 upregulated and 128 downregulated DEGs. In the PPI network, MLLT1, DLG2, and EFEMP1 were the hub proteins, in which DLG2 and EFEMP1 were involved in tumor progression. Among the top 10 up- and downregulated genes, the dysregulation genes of TPO, CDH16, and MPPED2 may be closely related to the tumorigenesis of PTC. By integrated analysis of multiple gene expression profiles, we propose that the dysregulation genes of TPO and MPPED2 will be the promising diagnostic markers for PTCs. PMID:26756467

    Introduction Thyroid carcinoma represents less than 1% of all cancers. The first line of treatment for thyroid cancer is partial/total thyroidectomy. High-dose Iodine131 therapy using Iodine radioisotopes is commonly used in patients with well differentiated thyroid carcinoma after total thyroidectomy. In this process, the non-thyroidal tissues, such as, salivary gland, stomach and breast tissues also take up radioactive iodine. Salivary gland scintigraphy is widely accepted as a sensitive and valid method for evaluation of salivary gland dysfunction after Radioactive Iodine131 Therapy (RIT). Aim To assess and compare the salivary flow rates, relative uptake and ejection fractions in parotid and submandibular glands just before and one month after Iodine131 therapy. Materials and Methods The study was conducted on 24 patients diagnosed with well differentiated thyroid carcinoma who underwent partial/total thyroidectomy and were due for radioactive iodine therapy. These patients were divided into two groups based on the lesion based dosimetry (Group A: 60-100Gy; Group B: 100-150Gy). Salivary gland assessment was done by salivary gland scintigraphy before and after RIT. Statistical Analysis The data collected was tabulated and statistically analysed using SPSS software version16 using paired t-test and individual sample t-test. Results A statistically significant difference in the uptake percent and ejection fraction percent in the parotid and submandibular glands before RIT and one month after RIT was observed in the study. Conclusion We inferred from the study that there was an overall decrease in uptake percent and ejection fraction percent one month post RIT in both parotid and submandibular glands. Also, a statistically significant difference was noted in the uptake and ejection fraction percent between Group A and Group B concluding the fact that the damage is dose related. PMID:26894178

    Calcitonin (CT), the major biochemical marker in medullary thyroid carcinoma (MTC) is prone to in vitro instability and suffers from scarcity of clinical laboratory platforms. Procalcitonin (PCT), the precursor of CT, free of these shortcomings, has been reported as a potential MTC marker. The aim of this study was to assess the negative predictive value (NPV) of PCT as a first-line marker in MTC. 476 serum samples referred to our laboratory for CT measurements were analyzed for PCT. NPVs of PCT were assessed at 3 cut-offs (0.05, 0.10 and 0.15 ng/mL) and the diagnosis of MTC was based on CT levels. PCT and CT levels were correlated (r=0.7554 for CT levels above 10 pg/mL, n=66). Accepting the CT cut-off based on the upper reference limit the NPV of PCT were 98.1% (0.05 ng/mL), 96.3% (0.10 ng/mL) and 95.4% (0.15 ng/mL) respectively. For a CT cut-off of 100 pg/mL the NPVs of PCT were 100% for all PCT thresholds. Serum PCT has a strong NPV and could be a good candidate for a first-line screening test to exclude MTC in patients with suspicious thyroid nodules or suggestive symptoms. Larger prospective studies are necessary to confirm our results. PMID:26806393

  2. What is the Minimal Surgery for Papillary Thyroid Carcinoma?

    Although thyroid surgery for treatment of papillary thyroid carcinoma (PTC) has been practiced for more than 100 years, there is still controversy regarding the minimal surgery needed for cure. The main reason for this controversy is lack of prospective randomized trials. The data accumulated in the last four decades indicate that hemithyroidectomy can be sufficient and safely practiced in low-risk patients with PTC. Patients <45 years of age with a single tumor less than 2 cm, with no lymphatic spread, and in the absence of other risk factors, can be equally managed by hemithyroidectomy or total thyroidectomy. A slight increase in the risk of vocal cord paralysis and hypocalcemia after total thyroidectomy suggests that hemithyroidectomy is appropriate for the management of patients with stage T1 disease. Any choice regarding the extent of surgery should be made with the patient and his family and in a multidisciplinary setup, which has been shown to improve decision-making procedures before the operation and during follow-up.

    In a total of 1665 patients with malignant thyroid neoplasms 90 oxyphilic thyroid carcinomas (OTC) were found of whom 55 could be re-examined and newly classified. Morphological and clinical parameters influencing the clinical course were determined. During a mean follow-up period of 6.5 y metastases or local recurrent disease occurred in 12 patients (24%). Apart from 3 early manifestations of metastases, 9 patients developed recurrent disease within, on average, 4.7 y after thyroidectomy: local lymph node metastases and local recurrences occurred within an average of 5.4 y, distant metastases after only 2.7 y. Thyroglobulin proved to be reliable for follow-up with a sensitivity of 88% on levothyroxine and 75% on endogenous TSH-stimulation (specificity: 98%). The frequency of metastases and local recurrences correlated with age at the time of tumor diagnosis, the degree of invasiveness and the local tumor extension (pT4 vs. pT1-3), whereas other factors such as the absolute diameter of the tumor or patient's sex had no influence on the clinical course. The survival probability for 5 and 10 years was 95 and 75%, respectively. All OTC patients should be examined regularly at least once a year by cervical sonography and thyroglobulin measurement. Because 18% recurrences occurred within 4.7 y such examinations should be repeated beyond year 5 after thyroidectomy. PMID:1491962

    Circulating afamin (AFM) concentrations have been investigated as a tumor biomarker in various types of carcinomas. However, suitable cell lines expressing human afamin have not yet been reported and current knowledge of the functions of afamin, particularly at the mechanistic molecular level, is very limited. In the current study, thyroid cancer cell lines 8505c and K1 were used to investigate the potential functions of afamin. AFM over-expression models and vector controls of 8505c (8505c + AFM and 8505c + NC) and K1 (K1 + AFM and K1 + NC) were successfully established by Lenti-LV5-AFM and Lenti-LV5-NC transfection. The change of gene expression was detected by qRT-PCR and western blotting analysis. (18)F-FDG imaging in xenografts model was performed using a micro PET/CT. We found that protein level of GAPDH, GLUT1, HK2, p-AKT, AKT, p-mTOR and PARP1 were up-regulated in K1 + AFM cells when compared to K1 and K1 + NC. While in 8505c, 8505c + NC and 8505c cells, the expression level of these genes were not significantly changed. (18)F-FDG uptake was much higher in K1 + AFM cells when compared to K1 and K1 + NC in vitro and in vivo. In conclusion, afamin could promote glycometabolism by up-regulating the glucose metabolism key enzymes in papillary thyroid carcinoma. These findings reveal new clues of the molecular function of AFM. PMID:27329154

    Diarrhoea, which is present in roughly one third of cases of medullary carcinoma of the thyroid, was investigated in five cases. Excessive loss of water and electrolytes in the stools was the major factor. Steatorrhoea was mild or absent, and intestinal absorption of glucose and vitamin B12 was normal; the histological appearance of the small intestinal mucosa was normal or subnormal. Water and sodium diarrhoea seems to be linked to a sometimes considerable increase in the rate of transit through the small intestine and colon, and may be relieved by codeine or codethyline. The frequent increase in the maximum blood sugar level during an oral tolerance test should not be interpreted as evidence of a paradiabetic condition. In fact, the intravenous glucose tolerance test is usually normal and the excessive rise in blood sugar after oral administration seems to be the consequence of the increased rate of transit through the small intestine. The link between the tumour and the disordered motility seems definite in view of certain cases in which removal of the tumour caused the diarrhoea to disappear immediately. Production by the tumour of serotonin or other derivatives of tryptophan or of kallikrein, which activates bradykinin, is rare. With regard to prostaglandins, high concentrations have been observed in the tumours and in the venous blood draining the tumours, but their presence in systemic blood is inconstant. The only hormonal substance, concentration of which seems to be definitely increased in the systemic blood of patients with a medullary carcinoma of the thyroid, is thyrocalcitonin but this hormone does not seem to have any effect on the motor activity of the digestive tract.

    Development of thyroid nodule during pregnancy is rare, however the cancer rate of this nodule is high. Herein, we present medical outcomes of three pregnant women who were operated with the diagnosis of differentiated thyroid carcinoma in the light of literature. As sonographic findings of three cases showed malignant characteristics, fine needle aspiration biopsy (FNAB) was performed. Cytological examination result was reported as papillary thyroid carcinoma (PTC). Surgery was performed in the second trimester in all cases. One case underwent total thyroidectomy with neck dissection at level III and VI and two cases underwent total thyroidectomy with neck dissection at level VI. Pathological examination result was also reported as PTC. Lymph node metastases in the dissected materials were detected. During the intraoperative and early postoperative period, no complications occurred and no findings of recurrence or residues were observed during one-year follow-up following surgery. In conclusion, as the first trimester has an increased risk of congenital malformations, elective surgery should be performed at the second trimester, if applicable. In pregnants with malignant sonographic features and PTC confirmed by FNAB, surgery can be applied safely by taking precautions during pre-/peri- and postoperative period. These patients should not be given premedication for anesthesia, should be properly positioned and teratogenic agents should be avoided. After surgery, mother and fetus should be monitored closely.

    Despite a more advanced stage of disease at presentation, a better response to radioiodine (RAI) therapy and a reduced overall mortality have been reported in pediatric differentiated thyroid cancer (DTC) in comparison to adult DTC. Few studies suggested that the better response to RAI therapy in pediatric patients might be associated with an increased expression of NIS. However, a marked heterogeneity within the pediatric group has been recognized. Children (<10 years old) usually present a more aggressive disease than adolescents (≥10–18 years old). By analyzing the expression of thyroid-specific genes in 38 sporadic pediatric tumors, we show that the expression of NIS, PDS, and TSHR was lower in children than adolescents (P < 0.05). A linear regression confirmed the association between NIS expression and age. Most significantly, NIS was expressed at similar levels in DTC from children and adults, whereas PDS and TSHR expression was even lower in DTC from children, compared to adolescents and adults. Our data suggest that biological behaviors of DTC in adolescents might differ from those in children and adults. Therefore, the premise that the expression of thyroid-specific genes is higher in tumors from pediatric patients than in adults is not entirely true and might be too oversimplified. PMID:27022395

For evaluation of hypercalcemia, (99m) Tc-MIBI scintigraphy was done and showed focal uptake at the thyroid level of the right anterior neck. Subsequent neck sonography showed several thyroid nodules, but there was no parathyroid tumor. Percutaneous fine-needle aspiration of the dominant thyroid nodule indicated a follicular nodule. After surgery, final histopathology revealed intrathyroidal parathyroid carcinoma. This case illustrates the difficulty in diagnosing parathyroid carcinoma via fine-needle aspiration. PMID:24037737

    In the majority of cases, carcinoma of the thyroid presents as a cold nodule by radioiodine and Tc-99m sodium pertechnetate scintigraphy. Whereas the presence of a hot nodule usually implies a benign entity, it does not provide complete assurance against thyroid malignancy. Presented is a rare case of metastatic pure papillary thyroid carcinoma appearing as a hot nodule on Tc-99m sodium pertechnetate and I-123 sodium iodide scintigraphy. The implications of such a case, its management, and review of the pertinent literature are discussed. PMID:9619317

    The role of thallium-201 ({sup 201}TI) scintigraphy in the follow-up evaluation of differentiated thyroid carcinoma (DTC) is controversial. Desirable characteristics of {sup 201}TI scintigraphy including the potential for no thyroid hormone withdrawal, immediate imaging postinjection, and low radiation burden relative to iodine-131 ({sup 131}I) suggests it is logistically superior to {sup 131}I scintigraphy. Fifty-two patients with DTC were evaluated with {sup 201}TI and {sup 131}I neck and chest images, and serum thyroglobulin measurements. In post-thyroidectomy and pre-{sup 131}I ablation therapy patients, very little {sup 201}TI accumulation was noted within the thyroid bed, with discordantly increased {sup 131}I activity and normal serum thyroglobulin measurements. Twenty-nine percent of patients evaluated after {sup 131}I ablative therapy had elevated serum thyroglobulin levels and localized neck and chest abnormalities on 201TI scan that were not seen on {sup 131}I studies. Our data suggest that {sup 201}TI is more sensitive than {sup 131}I diagnostic (5 mCi) studies for detection of DTC, while {sup 131}I is more sensitive in detecting normal residual thyroid tissue postoperatively.

    A 70-year-old man with prostate cancer and increased prostate-specific antigen level of 55 ng/mL underwent staging F-fluorocholine PET/CT, which demonstrated the primary prostate tumor and a focal area corresponding to a 2-cm hypodense nodule in the left thyroid lobe. Fine-needle aspiration and subsequent total thyroidectomy with central lymph node dissection showed an oxyphilic papillary thyroid carcinoma and a medullary microcarcinoma. Oxyphilic tumors represent a significant proportion of the few case reports of incidental focal thyroid fluorocholine thyroid uptake. PMID:26914574

    Background microRNAs (miRNAs) are a group of non-coding single stranded RNAs measuring approximately 22 nt in length that have been found to control cell growth, differentiation and apoptosis. miRNAs negatively regulate their target genes and recently have been implicated in tumourigenesis. Furthermore, miRNA expression profiling correlates with various cancers, with these genes thought to act as both tumour suppressors and oncogenes. ret/PTC 1 is an oncogene with constitutive kinase activity implicated in the development of papillary thyroid carcinoma (PTC). This rearrangement leads to aberrant MAPK activation that is implicated in PTC tumourigenesis. Aim The aim of this study was to identify the effect that ret/PTC 1 has on transcription and post-transcriptional regulation in PTC by using DNA microarray and microRNA analysis. Results DNA microarray analysis revealed a group of genes differentially expressed between normal thyroid cell lines and those harbouring a ret/PTC 1 rearrangement. Furthermore, a unique miRNA expression signature differentiated between PTC cell lines with ret/PTC 1 and a normal thyroid cell line. 21 miRNAs showed significant overexpression and 14 miRNAs showed underexpression in these cell lines when compared to normal thyroid. Several of these up/down regulated miRNAs may be involved in PTC pathogenesis. PMID:17156473

    During the past 38 years, 260 patients with thyroid carcinoma have been operated upon at the University of California Hospital. In 26 of these patients the first symptom was a mass distant from the thyroid gland, and the gland was considered normal on clinical examination. In all but three of the 26 cases a small carcinoma of the thyroid gland was observed at operation or in pathological examination. Radical neck dissection with either total lobectomy or total thyroidectomy would seem to be the operation of choice in the treatment of these patients. The ultimate prognosis, even in the presence of metastases, is relatively good. Primary carcinoma of the thyroid gland should be considered in the presence of tumors of the side of the neck even in the absence of palpable nodules in the gland itself. ImagesFigure 2.

    The recognition of bronchioloalveolar carcinoma (BAC) as distinct from adenocarcinoma of the lung, is controversial. Using strict pathologic criteria, 43 consecutive patients with BAC were matched by year of diagnosis and compared with a similar number of patients with adenocarcinoma, and for contrast, with those with squamous and oat cell carcinoma of the lung. We demonstrated that BAC is not sex related, and is not as smoking related as the other neoplasms. Unlike epidermoid carcinoma, BAC does not show a predilection for those occupations requiring manual labor. Also, BAC is frequently distinguishable radiologically from the other three by being smaller and peripheral. A pleural tag and an air bronchogram in a mass are rather specific, and BAC is less likely to have large airway involvement and adenopathy. The percentage of patients who were free of tumor after 2 yr was greater in the BAC group than in the others, but the overall survival rate between the BAC group and the adenocarcinoma group was not. Based on inter-observer variability, there is some overlap pathologically between these 2 groups. However, when the overlap between the adenocarcinoma and the BAC groups is compared with that between the adenocarcinoma and the squamous cell carcinoma groups, the difference is not significant. We conclude that BAC should be considered a distinct clinical entity. PMID:6278997

    The Wnt/β-catenin signaling pathway is involved in the normal development of thyroid gland, but its disregulation provokes the appearance of several types of cancers, including papillary thyroid carcinomas (PTC) which are the most common thyroid tumours. The follow-up of PTC patients is based on the monitoring of serum thyroglobulin levels which is regulated by the thyroid transcription factor 1 (TTF-1): a tissue-specific transcription factor essential for the differentiation of the thyroid. We investigated whether the Wnt/β-catenin pathway might regulate TTF-1 expression in a human PTC model and examined the molecular mechanisms underlying this regulation. Immunofluorescence analysis, real time RT-PCR and Western blot studies revealed that TTF-1 as well as the major Wnt pathway components are co-expressed in TPC-1 cells and human PTC tumours. Knocking-down the Wnt/β-catenin components by siRNAs inhibited both TTF-1 transcript and protein expression, while mimicking the activation of Wnt signaling by lithium chloride induced TTF-1 gene and protein expression. Functional promoter studies and ChIP analysis showed that the Wnt/β-catenin pathway exerts its effect by means of the binding of β-catenin to TCF/LEF transcription factors on the level of an active TCF/LEF response element at [−798, −792 bp] in TTF-1 promoter. In conclusion, we demonstrated that the Wnt/β-catenin pathway is a direct and forward driver of the TTF-1 expression. The localization of TCF-4 and TTF-1 in the same area of PTC tissues might be of clinical relevance, and justifies further examination of these factors in the papillary thyroid cancers follow-up.

    Background Well-differentiated thyroid cancer (WDTC) is the most common form of thyroid malignancy. While it is typically associated with good prognosis, it may exhibit higher recurrence and mortality rates in selected groups, particularly Filipinos. This paper aims to describe the experience of a Philippine Hospital in managing patients with differentiated thyroid cancer. Methods We performed a retrospective cohort study of 723 patients with WDTC (649 papillary and 79 follicular), evaluating the clinicopathologic profiles, ultrasound features, management received, tumor recurrence, and eventual outcome over a mean follow-up period of 5 years. Results The mean age at diagnosis was 44±13 years (range, 18 to 82), with a majority of cases occurring in the younger age group (<45 years). Most tumors were between 2 and 4 cm in size. The majority of papillary thyroid cancers (PTCs, 63.2%) and follicular thyroid cancers (FTCs, 54.4%) initially presented as stage 1, with a greater proportion of FTC cases (12.7% vs. 3.7%) presenting with distant metastases. Nodal metastases at presentation were more frequent among patients with PTC (29.9% vs. 7.6%). A majority of cases were treated by complete thyroidectomy, followed by radioactive iodine therapy and thyroid stimulating hormone suppression, resulting in a disease-free state. Excluding patients with distant metastases at presentation, the recurrence rates for papillary and FTC were 30.1% and 18.8%, respectively. Conclusion Overall, PTC among Filipinos was associated with a more aggressive and recurrent behavior. FTC among Filipinos appeared to behave similarly with other racial groups. PMID:26754584

    ABSTRACT Oncogenic mutations in BRAF are common in melanoma and thyroid carcinoma and drive constitutive activation of the MAPK pathway. Molecularly targeted therapies of this pathway improves survival compared to chemotherapy; however, responses tend to be short-lived as resistance invariably occursCell line models of melanoma and thyroid carcinoma, +/− BRAFV600E activating mutation, were treated with the MEK inhibitor PD0325901. Treated and naive samples were assayed for expression of key members of the MAPK pathway. Global microRNA expression profiling of naive and resistant cells was performed via next generation sequencingand indicated pluripotency pathways in resistance. Parental cell lines were progressed to holoclones to confirm the miRNA stemness profileMembers of the MIR302/373/374/520 family of embryonic stem cell specific cell cycle regulating (ESCC) microRNAs were identified as differentially expressed between resistant BRAFV600E melanoma and thyroid cell lines. Upregulated expression of gene and protein stemness markers, upregulated expression of MAPK pathway genes and downregulation of the ESCC MIR302 cluster in BRAFV600E melanoma indicated an increased stem-like phenotype in resistant BRAFV600E melanoma. Conversely, downregulated expression of gene and protein stemness markers, downregulated expression of MAPK pathway genes, upregulation of the ESCC MIR520 cluster, reeexpression of cell surface receptors, and induced differentiation-associated morphology in resistant BRAFV600E indicate a differentiated phenotype associated with MEK inhibitor resistance in BRAFV600E thyroid cellsThe differential patterns of resistance observed between BRAFV600E melanoma and thyroid cell lines may reflect tissue type or de novo differentiation, but could have significant impact on the response of primary and metastatic cells to MEK inhibitor treatment. This study provides a basis for the investigation of the cellular differentiation/self-renewal access and its role

    Metastases to the pituitary gland and sella turcica are uncommon. The distinction between primary and secondary metastatic pituitary tumours is challenging as carcinomas from distant sites might closely resemble, both clinically and histopathologically, non-functional adenomas or primary pituitary carcinomas. Among metastases to pituitary gland ones from thyroid carcinoma are extremely rare. We present a unique case of a 53-year-old male patient with a past history of thyroid carcinoma who underwent repeated surgeries over a period of 7 years for a sellar-parasellar mass with paranasal sinus involvement. Morphologically, the tumour was composed of solid sheaths of monomorphic cells exhibiting oncocytic features. In electron microscope images, the cytoplasm of tumour cells was filled with numerous mitochondria. The tumour was negative for pituitary hormones but exhibited immunoreactivity for cytokeratin AE1/AE3, thyroglobulin and thyroid transcription factor 1 (TTF-1). Based on the clinical data and immunophenotypic profile, the tumour was finally diagnosed as an oncocytic variant of follicular thyroid carcinoma. To our knowledge, this is probably the first report of such peculiar histopathological variant of follicular thyroid carcinoma metastasizing to the pituitary gland. The diagnostic dilemmas considering oncocytic features of the presented case are discussed. PMID:24114644

    Background: Differentiated thyroid carcinomas originating from thyroid follicular cells are frequent tumors of the thyroid with relatively good prognosis due to improved surgical techniques and follow-up procedures. Poorly differentiated thyroid cancers, which lose iodine uptake ability, in most cases still express thyrotropin (TSH) receptors (TSHR). Therefore, the aim of this study was to radiolabel a superagonist recombinant human TSH (rhTSH) analogue for imaging poorly differentiated thyroid cancer. Methods: The TSHR superagonist, TR1401, was labeled with 99mTc using an indirect method via succinimidyl-6-hydrazinonicotinate hydrochloride conjugation. In vitro quality controls included SDS-PAGE, cysteine challenge, and cell-binding assay on TSHR positive cell lines (JP09 and ML-1). In vivo studies included tumor targeting experiments in athymic nude CD-1 mice xenografted with several different TSHR positive cells (JP09, K1, and ML-1) and TSHR negative cells (JP02) as control. Results: The superagonist rhTSH analogue TR1401 was labeled with high labeling efficiency (>95%) and high specific activity (9250 MBq/mg). The labeled molecule retained its biologic activity and structural integrity. In tumor targeting experiments, a focal uptake of radiolabeled TR1401 was observed in TSHR positive cells but not in TSHR negative cells. The same observation was made in a dog with spontaneous intraglandular thyroid cancer. Conclusions: We were able to radiolabel the rhTSH superagonist analogue TR1401 with 99mTc efficiently with retention of in vitro and in vivo binding capacity to TSHR. The relative role of such novel radiopharmaceutical versus 131I scanning of thyroid cancer will require future histopathologic and clinical studies, but it may open new perspectives for presurgical staging of thyroid cancer, and diagnosis of radioiodine negative local relapses and/or distant metastases.

    Medullary thyroid carcinoma (MTC) is a rare form of malignancy, having an intermediate prognosis. Controversies exist regarding the best surgical approach. The aim of the study was to analyze the outcome in a group of patients with MTC, diagnosed and followed up in a single care center. We performed a retrospective analysis of all the patients diagnosed with MTC in the Department of Endocrinology from the County Emergency Hospital Timisoara between 1992 and 2012. The study group included 19 patients, 6 men (31.6 %), mean age 41.2 ± 12.5 years (20-72 years). The preoperative diagnosis was based on the protocol for nodular thyroid disease. Total or near-total thyroidectomy was performed in 10 out of 16 patients who could be operated. Postoperative follow-up included repeated measurements of serum calcitonin and imaging investigations. Nine out of the total of 19 (47.3 %) patients had hereditary forms of MTC. Most of the cases (84.2 %) were submitted to surgery. The median duration of follow-up was 84 months. The pTNM staging indicated that the majority of the patients with hereditary MTC were diagnosed in an earlier stage. Disease remission was achieved in 7 cases (43.8 %). Four patients, all with sporadic forms, died. Survival rates at 1, 5 and 10 years were significantly higher (p = 0.048) in patients with hereditary MTC. An early diagnosis of MTC allows a better surgical approach and an improved survival rate. We support the general recommendation that modified radical neck dissection is not necessary for all the patients with MTC. PMID:27574350

    The aim of the present study was to assess the apparent diffusion coefficient (ADC) in diffusion-weighted imaging (DWI), thyroid radioactive iodine uptake (RAIU), thyroid scintigraphy and thyrotropin receptor antibody (TRAb) levels in the differential diagnosis between Graves' disease (GD) and painless thyroiditis (PT). A total of 102 patients with GD and 37 patients with PT were enrolled in the study. DWI was obtained with a 3.0-T magnetic resonance scanner, and ADC values were calculated. RAIU and thyroid scintigraphy were performed. Tissue samples were obtained from patients with GD (6 cases) following thyroidectomy, and from patients with PT (2 cases) following biopsy. Receiver operating characteristic (ROC) curves were drawn, optimal cut-off values were selected, and the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were assessed. It was found that the ADC, TRAb and RAIU were significantly higher in GD than in PT (P<0.05). ROC curves showed areas under the curves for RAIU, ADC and TRAb that were >0.900. RAIU was the reference method. Sensitivity, specificity, accuracy, PPV and NPV were 96.078, 91.892, 95.000, 97.059 and 89.474% for ADC, and 88.235, 75.676, 84.892, 90.909 and 70.000% for TRAb, after the optimal thresholds of 1.837×10−3 mm2/sec and 1.350 IU/ml were determined respectively. Histopathology showed that tissue cellularity in PT was much higher than in GD due to massive lymphocytic infiltration. The results of the present study indicate that RAIU, ADC and TRAb are of diagnostic value for differentiating between GD and PT. DWI has great potential for thyroid pathophysiological imaging because it reflects differences in tissue cellularity between GD and PT. PMID:26136954

    Generally, calcitonin (CT) values below the upper reference limit rule-out medullary thyroid carcinoma (MTC) with very high accuracy. However, sparse cases of serum-calcitonin-negative MTC (CT-NEG-MTC) have been reported. Here we reviewed CT-NEG-MTC reported in literature, discussed the potential causes and proposed a practical laboratory and clinical approach. A comprehensive literature search was conducted by using the terms "medullary thyroid carcinoma" AND "non-secreting calcitonin" OR "undetectable calcitonin". The search was updated until December 2014. Original articles that described CT-NEG-MTC were eligible for inclusion. Only MTC cases with preoperative CT below the upper reference limit were included in the present review. Eleven papers with 18 CT-NEG-MTC cases (age 50 years, size 26 mm) were retrieved. Four patients with poorly differentiated MTC died within 3 years. Different CT assays were employed and different reference values were adopted. Preoperative serum CT values were below the institution cut-off levels in all cases, and undetectable in four patients. In some papers negative CT results were confirmed by additional tests. Further laboratory investigations were performed in some of the included studies. In patients with well founded suspicious of MTC and within the reference limits/undetectable CT other laboratory investigations [carcinoembryonic antigen (CEA), procalcitonin, CT stimulation, CT in washout of nodule's aspiration] have to be performed. Surgical approach to CT-NEG-MTC does not differ from those secreting CT. Postoperative follow-up of these rare cases should include periodical imaging and measurement of all potential markers. Patients with poorly differentiated MTC are at higher risk of disease-related death, and require more aggressive follow-up strategy. PMID:25781697

    Total levels of thyroxine (T4) and thyroid-stimulating hormone (TSH) were measured in 37 patients who had previously had carcinoma of the larynx treated by radiotherapy and total laryngectomy with thyroid lobectomy. Ten percent of the patients had clinical features of hypothyroidism and 30% had total T4 levels below the lower limit of normal. A further 40% had results in the low normal range. Forty-four percent of patients had raised TSH levels, 90% of these having low or low normal T4 levels. The histology of the thyroid gland was normal in all 37 patients. Attention should be given to preserving intact the vasculature of the contralateral thyroid lobe whenever it is necessary to remove the ipsilateral thyroid lobe during a laryngectomy. Proper postoperative assessment of thyroid gland function is desirable in all these patients to identify those at risk of hypothyroidism and to avoid unnecessary morbidity.

    First introduced in 1946, radioactive iodine (I-131) produces short-range beta radiation with a half-life of 8 days. The physical properties of I-131 combined with the high degree of uptake in the differentiated thyroid cancers (DTCs) led to the use of I-131 as a therapeutic agent for DTC in adults. There are two indications for the potential use of I-131 therapy in pediatric thyroid disorders: nonsurgical treatment of hyperthyroidism owing to Graves' disease and the treatment of children with intermediate- and high-risk DTC. However, children are not just miniature adults. Not only are children and the pediatric thyroid gland more sensitive to radiation than adults but also the biologic behavior of DTC differs between children and adults as well. As opposed to adults, children with DTC typically present with advanced disease at diagnosis; yet, they respond rapidly to therapy and have an excellent prognosis that is significantly better than that in adult counterparts with advanced disease. Unfortunately, there are also higher rates of local and distant disease recurrence in children with DTC compared with adults, mandating lifelong surveillance. Further, children have a longer life expectancy during which the adverse effects of I-131 therapy may become manifest. Recognizing the differences between adults and children with DTC, the American Thyroid Association commissioned a task force of experts who developed and recently published a guideline to address the unique issues related to the management of thyroid nodules and DTC in children. This article reviews the epidemiology, diagnosis, staging, treatment, therapy-related effects, and suggestions for surveillance in children with DTC, focusing not only on the differences between adults and children with this disease but also on the latest recommendations from the inaugural pediatric management guidelines of the American Thyroid Association.

    The aim of this study was to evaluate the oncologic safety of robot thyroid surgery compared to open thyroid surgery for papillary thyroid carcinoma (PTC). We enrolled 722 patients with PTC who underwent a total thyroidectomy with central compartment node dissection (CCND) from January 2009 to December 2010. These patients were classified into open thyroid surgery (n = 610) or robot thyroid surgery (n = 112) groups. We verified the impact of robot thyroid surgery on clinical recurrence and ablation/control-stimulated thyroglobulin (sTg) levels predictive of non-recurrence using weighted logistic regression models with inverse probability of treatment weighting (IPTW). Age, sex, thyroid weight, extent of CCND, and TNM were significantly different between the two groups (p < 0.05); however, there was no significant difference in recurrence between the open and robot groups (1.5% vs. 2.7%; p = 0.608). The proportion of patients with ablation sTg < 10.0 ng/mL and control sTg < 1.0 ng/mL was comparable between the two groups (p > 0.05). Logistic regression with IPTW using the propensity scores estimated by adjusting all of the parameters demonstrated that robot thyroid surgery did not influence the clinical recurrence (OR; 0.784, 95% CI; 0.150–3.403, p = 0.750), ablation sTg (OR; 0.950, 95% CI; 0.361–2.399, p = 0.914), and control sTg levels (OR; 0.498, 95% CI; 0.190–1.189, p = 0.130). Robot thyroid surgery is comparable to open thyroid surgery with regard to oncologic safety in PTC patients. PMID:27285846

    Anaplastic Thyroid carcinoma is an extremely aggressive solid tumor that resists most treatments and is almost always fatal. Galectin-3 (Gal-3) is an important marker for thyroid carcinomas and a scaffold of the K-Ras protein. S-trans, transfarnesylthiosalicylic acid (FTS; Salirasib) is a Ras inhibitor that inhibits the active forms of Ras proteins. Modified citrus pectin (MCP) is a water-soluble citrus-fruit-derived polysaccharide fiber that specifically inhibits Gal-3. The aim of this study was to develop a novel drug combination designed to treat aggressive anaplastic thyroid carcinoma. Combined treatment with FTS and MCP inhibited anaplastic thyroid cells proliferation in vitro by inducing cell cycle arrest and increasing apoptosis rate. Immunoblot analysis revealed a significant decrease in Pan-Ras, K-Ras, Ras-GTP, p-ERK, p53, and Gal-3 expression levels and significant increase in p21 expression levels. In nude mice, treatment with FTS and MCP inhibited tumor growth. Levels of Gal-3, K-Ras-GTP, and p-ERK were significantly decreased. To conclude, our results suggest K-Ras and Gal-3 as potential targets in anaplastic thyroid tumors and herald a novel treatment for highly aggressive anaplastic thyroid carcinoma. PMID:27551476

    An unusual case of iodide-induced thyrotoxicosis is documented in this article. The patient was a 64-year-old euthyroid man with acromegaly. He also had multiple follicular and papillary thyroid carcinomas with a metastatic lesion in the lumbar vertebrae. After a total thyroidectomy, he became slightly hypothyroid, and the lumbar lesion began to incorporate /sup 131/I by scintigraphy. When an iodine-containing contrast medium happened to be injected, a transient increase of serum thyroid hormone level was observed. After complete thyroid ablation with 83 mCi of /sup 131/I, the oral administration of 100 mg of potassium iodide for 7 days induced a prominent increase of serum thyroid hormone level. These findings indicated that the metastatic thyroid carcinoma could produce excess thyroid hormone insofar as a sufficient amount of iodide was given. Although this is the first report of such a case, iodide-induced thyrotoxicosis may not be rare in patients with thyroid carcinomas because the Wolff-Chaikoff effect is thought to be lost, and the organic iodinating activity and lysosomal protease activity are well-preserved.

    Malignant melanoma can be successfully treated when it is identified in its early stages, but the disease is associated with a poor prognosis when it is detected in an advanced stage. Papillary thyroid carcinoma is a thyroid cancer that has a good prognosis. The present study reports a rare case of malignant melanoma and papillary thyroid carcinoma that were diagnosed concurrently and treated simultaneously. The present patient was a 37-year-old male, in whom examination of a skin biopsy that was obtained from a lesion in the right retroauricular region revealed the lesion to be consistent with malignant melanoma. The patient underwent radical neck dissection upon the detection of malignant melanoma metastasis to the sentinel lymph node. Metastases of papillary thyroid carcinoma were detected in four out of 38 lymph nodes. The patient was then diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy. The patient was administered with high-dose followed by moderate-dose interferon-α therapy for the treatment of malignant melanoma. The patient also received concurrent radioactive iodine therapy for the treatment of papillary thyroid carcinoma, at the same time as the interferon therapy. The two primary tumors of the patient were treated successfully. During therapy, no serious side-effects were observed, with the exception of fever caused by high-dose interferon therapy. Malignant melanoma and papillary thyroid carcinoma may occur concurrently, although this is rarely observed. The present study reports a rare case that demonstrates that the two tumors can be successfully treated simultaneously. PMID:25436010

    Introduction: Thyroid carcinoma initially presents with clinical symptoms due to metastatic lesions in less than 5% of cases. Spinal cord compression from an epidural metastatic lesion as a first symptom is extremely rare. One would expect such a presentation to occur much later in the course of the disease. Methods: We are presenting a case report of a follicular thyroid carcinoma that presented with spinal cord compression from a thoracic epidural metastatic lesion in a previously healthy 55-year-old male. A single metastasis of follicular thyroid carcinoma presenting with posterior spinal cord compression is rare. In this particular case, our management included a mid-thoracic laminectomy, followed by resection of the epidural lesion. Once the surgical pathology confirmed the diagnosis of a follicular thyroid carcinoma, the general surgery team performed a near total thyroidectomy, after which he received radioactive iodine therapy. The patient is symptom-free at his three-year follow-up. Conclusion: Initial presentation of follicular thyroid carcinoma with symptomatic thoracic myelopathy from an epidural metastasis is very uncommon. An early diagnosis and prompt surgical intervention provided an excellent outcome. PMID:26623201

    Genes regulated cell-cell and cell-matrix adhesion and degradation of the extracellular matrix (ECM) have been screened as potential markers of malignant thyroid nodules. The mRNA expression levels of two of them, the ECM protein-1 (ECM1) and the type II transmembrane serine protease-4 (TMPRSS4), were shown to be an independent predictor of an existing thyroid carcinoma. The vitamin D receptor (VDR) is expressed in epithelial cells of the normal thyroid gland, as well as in malignant dividing cells, which respond to the active metabolite of vitamin D by decreased proliferative activity in vitro. We evaluated the relationship between mRNA gene expressions of TMPRSS4, ECM1 and VDR in 21 papillary thyroid carcinoma samples and compared it to 21 normal thyroid tissues from the same patients. Gene expression was considered as up- or down-regulated if it varied by more or less than 2-fold in the cancer tissue relative to the normal thyroid tissue (Ca/N) from the same patient. We found an overall significant adjusted correlation between the mRNA expression ratio (ExR) of VDR and that of ECM1 in Ca/N thyroid tissue (R=0.648, P<0.001). There was a high ExR of VDR between Ca/N thyroid tissue from the same patient (3.06±2.9), which also exhibited a high Ca/N ExR of ECM1 and/or of TMPRSS4 (>2, P=0.05).The finding that increased VDR expression in human thyroid cancer cells is often linked to increased ECM1 and/or TPMRSS4 expression warrants further investigation into the potential role of vitamin D analogs in thyroid carcinoma.

    Abstract Here we present the case of a 14-yr-old girl who developed thyroid follicular carcinoma accompanied by Graves’ disease. She was diagnosed with Graves’ disease at 10 yr of age and soon achieved a euthyroid state after starting treatment. When she was 13 yr of age, her hyperthyroidism and goiter worsened despite medical therapy. Multiple nodules were found in her enlarged thyroid gland by ultrasonography. Her serum Tg level seemed within the normal range. She underwent near-total thyroidectomy for control of thyroid function. Histopathological study demonstrated that multiple oxyphilic follicular neoplasms were surrounded by the thyroid tissue compatible with Graves’ disease. Capsular invasion was identified in one of the nodules, and thus the histological diagnosis was minimally invasive follicular carcinoma. She did not have signs suggesting metastasis, and has had no relapse for 18 mo after the operation. Although some previous studies showed a high prevalence of thyroid cancer with an aggressive nature in adult patients with Graves’ disease, few reports about thyroid cancer accompanied by Graves’ disease are available in children. The present case, however, suggests that careful investigation is needed when we detect thyroid nodules or progressive thyroid enlargement, especially in children with Graves’ disease. PMID:24790388

    This study attempted to review the impact of extent of squamous differentiation in 56 infiltrating duct carcinomas (IDC) with squamous differentiation (metaplastic squamous carcinomas [MSC]). Tumors showing 100% squamous elements were labeled as primary squamous carcinomas (PSC; n = 28) and compared with 28 MSC showing lesser squamous components. A clinicopathological comparison revealed that lymphovascular emboli were never seen in any PSC but were noted in 7/28 of other MSC, while perineural invasion was seen only in PSC and not in MSC. Nodal metastasis was significantly more in other MSC as opposed to PSC. Most MSC presented with 2- to 5-cm sized tumors while PSC were 5 to 10 cm in size. PSC showed cystic change while MSC did not. Disease free survival (DFS) for MSC versus PSC was 64% versus 39.8%, while overall survival (OAS) was 72.7% in MSC versus 66.7% in PSC. Tumor stage affected DFS in MSC while none of the factors affected DFS/OAS in PSC. The extent of squamous differentiation affected DFS with best behavior for metaplastic carcinomas showing <40% squamous elements and worse for those with >90% squamous component (P = .024). PSC of breast is an aggressive disease and show distinct clinicopathological features from other MSC, and though the current definition of MSC does not advocate quantifying the squamous element, clearly this affects prognosis.

    Thyroid-like follicular carcinoma of the kidney (TLFCK) is a provisional new entity of renal cell carcinoma (RCC). We herein reported and compared one TLFCK case and one PRCC case with thyroid-like feature. The former entirely consisted of thyroid-like follicular architecture and the tumor cells were diffusely positive for PAX-8, but negative for CK7, AMACR, and CD10. By contrast, both papillary architecture (~60%) and thyroid-like follicular architecture (~40%) were identified in the latter. Tumor cells in both histological components exhibited diffusely positive staining for PAX-8, CK7, AMACR, but negative for CD10. FISH analysis showed no aberration in TLFCK case but trisomy of chromosome 17 in PRCC case. Along with a brief literature review, we presented that recognition of TLFCK is important to distinguish it from other conditions that show thyroid-like features. Additionally, a diagnosis of TLFCK should be cautiously made when papillary component is present in the tumor. PMID:26663803

    This report describes the gross, histological, and immunohistochemical features of medullary thyroid carcinoma (MTC) with pulmonary metastases in a young dog. Sheets of pleomorphic cells supported by fibrous stroma characterized the primary mass, while metastatic nodules had a neuroendocrine pattern. Despite differing histologic features, all masses showed marked immunoreactivity against calcitonin and multiple neuroendocrine markers consistent with MTC. Although MTC is a well-recognized entity, it may be difficult to distinguish this mass from other thyroid neoplasms, necessitating immunohistochemical characterization. PMID:24690600

    Papillary thyroid carcinoma (PTC) is frequently associated with RET gene rearrangements that generate the so-called RET/PTC oncogenes. In this review, we examine the data about the mechanisms of thyroid cell transformation, activation of downstream signal transduction pathways and modulation of gene expression induced by RET/PTC. These findings have advanced our understanding of the processes underlying PTC formation and provide the basis for novel therapeutic approaches to this disease. PMID:17062879

    After surgery, patients with medullary thyroid carcinoma (MTC) should be assessed regarding the presence of residual disease, the localization of metastases, and the identification of progressive disease. Postoperatively, patients with MTC are staged to separate those at low risk from those at high risk of recurrence. The TNM staging system is based on tumor size, extra-thyroidal invasion, nodal metastasis, and distant spread of cancer. In addition, the number of lymph-node metastases, the number of compartments involved, and the postoperative calcitonin (CTN) and carcinoembryonic antigen (CEA) levels should be documented. The postoperative normalization of the serum CTN level is associated with a favorable outcome. When patients have basal serum CTN levels less than 150 pg/ml after a thyroidectomy, any persistent or recurrent disease is nearly always confined to lymph nodes in the neck. When the postoperative serum CTN level exceeds 150 pg/ml, patients should be evaluated with imaging procedures, including computed tomography (CT) of the neck and chest, contrast-enhanced magnetic resonance imaging (MRI) and ultrasound (US) of the liver, bone scintigraphy, MRI of the bone, and positron emission tomography (PET)/CT. One can estimate the growth rate of MTC metastases by quantifying increases in tumor size over time from sequential imaging studies analyzed with response evaluation criteria in solid tumors (RECIST), and by determining the tumor marker doubling time from sequential measures of serum CTN or CEA levels over multiple time points. One of the main challenges remains to find effective adjuvant and palliative options for patients with metastatic disease. Patients with persistent or recurrent MTC localized to the neck following thyroidectomy are candidates for neck operations, depending on the tumor extension. Once metastases appear, the clinician must decide which patients require therapy. This requires a balance between the (often) slow rate of tumor

    Context and Objective: Oncocytic thyroid carcinoma, also known as Hürthle cell thyroid carcinoma, accounts for only a small percentage of all thyroid cancers. However, this malignancy often presents at an advanced stage and poses unique challenges to patients and clinicians. Surgical resection of the tumor accompanied in some cases by radioactive iodine treatment, radiation, and chemotherapy are the established modes of therapy. Knowledge of the perturbed oncogenic pathways can provide better understanding of the mechanism of disease and thus opportunities for more effective clinical management. Design and Patients: Initially, two oncocytic thyroid carcinomas and their matched normal tissues were profiled using whole genome sequencing. Subsequently, 72 oncocytic thyroid carcinomas, one cell line, and five Hürthle cell adenomas were examined by targeted sequencing for the presence of mutations in the multiple endocrine neoplasia I (MEN1) gene. Results: Here we report the identification of MEN1 loss-of-function mutations in 4% of patients diagnosed with oncocytic thyroid carcinoma. Whole genome sequence data also revealed large regions of copy number variation encompassing nearly the entire genomes of these tumors. Conclusion: Menin, a ubiquitously expressed nuclear protein, is a well-characterized tumor suppressor whose loss is the cause of MEN1 syndrome. Menin is involved in several major cellular pathways such as regulation of transcription, control of cell cycle, apoptosis, and DNA damage repair pathways. Mutations of this gene in a subset of Hürthle cell tumors point to a potential role for this protein and its associated pathways in thyroid tumorigenesis. PMID:25625803

    After the accident at the Fukushima Daiichi Nuclear Power Plant, the thyroid ultrasound screening program for children aged 0-18 at the time of the accident was started from October 2011. The prevalence of thyroid carcinomas in that population has appeared to be very high (84 cases per 296,253). To clarify the pathogenesis, we investigated the presence of driver mutations in these tumours. 61 classic papillary thyroid carcinomas (PTCs), two follicular variant PTCs, four cribriform-morular variant PTCs and one poorly-differentiated thyroid carcinoma were analysed. We detected BRAF(V600E) in 43 cases (63.2%), RET/PTC1 in six (8.8%), RET/PTC3 in one (1.5%) and ETV6/NTRK3 in four (5.9%). Among classic and follicular variant PTCs, BRAF(V600E) was significantly associated with the smaller size. The genetic pattern was completely different from post-Chernobyl PTCs, suggesting non-radiogenic etiology of these cancers. This is the first study demonstrating the oncogene profile in the thyroid cancers discovered by large mass screening, which probably reflects genetic status of all sporadic and latent tumours in the young Japanese population. It is assumed that BRAF(V600E) may not confer growth advantage on paediatric PTCs, and many of these cases grow slowly, suggesting that additional factors may be important for tumour progression in paediatric PTCs.

    Elevated levels of carcinoembryonic antigen (CEA) or calcitonin after surgical therapy for medullary carcinoma of the thyroid gland (MCT) indicate the presence of residual or metastatic disease. CEA elevations appear to be prognostically more reliable in patients with metastatic disease and suggest a more virulent tumor. Attempts to stage the disease with use of conventional imaging techniques are usually inadequate, as is the therapy for disseminated or recurrent MCT. An indium-111-labeled anti-CEA monoclonal antibody (ZCE-025) was used to image metastases in a patient with MCT. Potential applications of monoclonal antibody technology in the management of MCT would include (1) preoperative differentiation of unicentric from multicentric thyroid gland involvement, (2) detection of regional or distant metastases or both, (3) measurement of response to systemic therapy, and (4) the facilitation of radionuclide immunoconjugate therapy.

    We evaluate the gray-scale ultrasonographic characteristics that differentiate between nodular hyperplasia (NH) and neoplastic follicular-patterned lesions (NFPLs) of the thyroid gland. Ultrasonographic features of 750 patients with 832 thyroid nodules (NH, n = 361; or NFPLs, follicular adenoma, n = 123; follicular carcinoma, n = 159; and follicular variant papillary carcinoma, n = 189) were analyzed. Except for echogenicity, over two-thirds of the cases of NH and NFPLs share the ultrasonographic characteristics of solid internal content, a well-defined smooth margin and round-to-ovoid shape. Independent predictors for NH were non-solid internal content (sensitivity 27.1%, specificity 90.2%), isoechogenicity (sensitivity 69.5%, specificity 63.5%) and an ill-defined margin (sensitivity 18.8%, specificity 94.5%). Independent predictors for NFPLs were hypoechogenicity (sensitivity 60.5%, specificity 70.4%), marked hypoechogenicity (sensitivity 2.8%, specificity 99.4%) and taller-than-wide shape (sensitivity 6.6%, specificity 98.1%). Although NH and NFPLs commonly share ultrasonographic characteristics, non-solid internal content and ill-defined margin are specific to NH and marked hypoechogenicity and taller-than-wide shape are specific to NFPLs.

    Thyroid nodules are encountered in clinical practice during the diagnostic procedures or patients' follow-up due to other diseases quite far from the thyroid gland with prevalence 4-50% in general population, depending on age, diagnostic method and race. The prevalence of thyroid nodules increases with age and their clarification should be done for their adequate treatment. An 18F-FDG PET/CT was done with a PET/CT scanner (Philips Gemini TF), consisting of dedicated lutetium orthosilicate full ring PET scanner and 16 slice CT. The PET/CT scan of the whole-body revealed on the CT portion a hypodense nodular lesion in the left lobe of the thyroid gland with increased uptake of 18F-FDG on the PET with SUVmax 10.3 and demonstrated a complete response to the induction therapy of the main oncological disease of the patient--squamous cell carcinoma. This clinical case demonstrates that whole-body 18F-FDG-PET/CT has an increasingly important role in the early evaluation of thyroid cancer as a second independent malignant localization. Focal thyroid lesion with high risk of thyroid malignancy was incidentally found on 18F-FDG PET/CT. PMID:25088110

    Abstract This study aims to investigate the impact of psammoma body (PB) on papillary thyroid carcinoma (PTC), and evaluate the association among PB, Hashimoto thyroiditis (HT), and other clinicopathologic characteristics in PTC patients. We conducted a retrospective case-control study involving 1052 PTC patients who underwent total thyroidectomy or lobectomy with lymph node dissection. Psammoma body was observed in 324 out of 1052 PTC (30.8%) patients. Ultrasonographic (US) calcification (P < 0.001), multifocality of the tumor (P = 0.047), lymph node metastasis (LNM) (P < 0.001), HT (P < 0.001), and Primary tumor (T), Regional lymph nodes (N), Distant metastasis (M) staging (P = 0.001) were significantly related to the presence of PB. The presence of PB was significantly associated with US microcalcification (P < 0.001). In the subgroup with HT, compared with the patients without PB, the patients with PB exhibited a higher frequency of central LNM (54.7% vs 32.1%; P < 0.001) and US microcalcification (94.7% vs 38.8%; P < 0.001), as well as smaller tumors (0.9 ± 0.6 vs 1.3 ± 0.9 cm; P < 0.001). In the subgroup without HT, the patients with PB displayed a higher incidence of lateral LNM (25.8% vs 14.6%; P < 0.001), US microcalcification (87.3% vs 52.5%; P < 0.001), and extrathyroidal extension (47.2% vs 34.8%; P = 0.001), as well as larger tumors (1.3 ± 0.9 vs 1.0 ± 0.8 cm; P < 0.001) than without PB. Moreover, in the subgroup with PB, the PTC patients with HT showed a higher LNM (77.9% vs 57.2%; P < 0.001) and a lower frequency of extrathyroidal extension (20.0% vs 47.2%; P < 0.001) than without HT. Psammoma body is a useful predictor of aggressive tumor behavior in PTC patients. HT with PB shows more aggressive behaviors than non-HT with PB in PTC patients. PMID:26554782

    Thyroid carcinoma is the most common malignancy of the endocrine system and it accounts approximately 1%-3% of all human cancers. Among the three subtypes of thyroid cancers, medullary thyroid carcinoma (MTC) is the most common cause of death in patients with multiple endocrine neoplasia (MEN) type 2A (MEN2A), MEN type 2B (MEN2B) and familial medullary thyroid carcinoma (FMTC). Generally, MTC accounts for up to 10% of all types of thyroid cancers. It is one of the aggressive forms of thyroid carcinoma which is manifested in childhood ages more than adults, and it comprises about 17% of all pediatric thyroid cancer. Like the other cancers, prevention of MTC is easier than its cure. In the recent decades (from 1993) the diagnosis of asymptomatic child carrying RET mutations in the affected families by MTC, has been provided by genetic screening, and prophylactic thyroidectomy is an efficacy therapeutic procedure. On the one hand, according to near the complete penetrance of the disease and its onset in the early years of life, it is required to accelerate the protection of at-risk children with relative affected by MTC and on the other hand, there are several obstructions to MTC treatment including: 1) the proband's refusal to disclose the RET mutation genetic testing results, 2) children's vulnerability because of their inability to participate in the informed consent, and 3) the existence of conflict between physicians and children's guardian. In this review article, the recommendations and ethical issues of MTC treatment in asymptomatic and at-risk children have been summarized. PMID:26974132

    The purpose of this prospective study was to determine the incidence of thyroid dysfunction in cancer patients receiving immunotherapy with interleukin-2 (IL-2) alone, and to assess the relationship of hypothyroidism to clinical response. A cohort of 281 consecutive patients with metastatic melanoma or renal carcinoma were treated with IL-2 alone from July 1, 1989 until June 30, 1993. The majority (n = 216) received high-dose IL-2 and the remainder (n = 65) received low-dose therapy. Thyroid function was measured before, during, and after immunotherapy. Forty-one percent of initially euthyroid patients developed thyroid dysfunction after starting high-dose IL-2-alone therapy. The most common abnormality was hypothyroidism, occurring in 35% of patients, although moderate or severe hypothyroidism requiring thyroid hormone replacement occurred in 9% of patients. Hypothyroidism was related to duration of IL-2 therapy and was not associated with clinical response. Hyperthyroidism developed in 7% of previously euthyroid patients receiving high-dose IL-2. Overall, the incidence of thyroid dysfunction was similar in the high- and low-dose IL-2 regimens. In conclusion, thyroid dysfunction is a common sequela of IL-2 therapy. Thyroid function should be measured routinely in cancer patients receiving IL-2-based treatment. It is recommended that thyroid hormone replacement be given to patients with moderate or severe hypothyroidism. PMID:8680655

    Over a period of 32 years from 1954 to 1986, 65 patients under the age of 21 years, 52 girls and 13 boys, were operated for nodular thyroids: the overall incidence of carcinoma was 37 per cent. It was 46 per cent in those patients presenting with a solitary nodule. Among the 24 patients with a malignancy, the carcinoma was of the papillary variety in 63 per cent, follicular in 25 per cent and medullary in 12 per cent. Two thirds of the patients had metastatic disease at the time of presentation. All patients with thyroid carcinoma were treated with total thyroidectomy. Other measures included neck dissection and radioactive iodine. When the eight patients with a history of head and neck irradiation and the three patients with medullary carcinoma were excluded, the incidence of carcinoma was 28 per cent. In summary, in spite of the decline in radiation associated cases, the incidence of carcinoma in nodular thyroid disease in the population under 21 years, remains at the relatively high figure of 28 per cent.

    Podoplanin (PDPN), a mucin-type transmembrane glycoprotein specific to the lymphatic system is expressed in a variety of human cancers, and is regarded as a factor promoting tumor progression. The purpose of this study was to elucidate the molecular role of PDPN in the biology of thyroid cancer cells. PDPN expression was evaluated in primary thyroid carcinomas and thyroid carcinoma cell lines by RT-qPCR, Western blotting, IF and IHC. To examine the role of podoplanin in determining a cell's malignant potential (cellular migration, invasion, proliferation, adhesion, motility, apoptosis), a thyroid cancer cell line with silenced PDPN expression was used. We observed that PDPN was solely expressed in the cancer cells of 40% of papillary thyroid carcinoma (PTC) tissues. Moreover, PDPN mRNA and protein were highly expressed in PTC-derived TPC1 and BcPAP cell lines but were not detected in follicular thyroid cancer derived cell lines. PDPN knock-down significantly decreased cellular invasion, and modestly reduced cell migration, while proliferation and adhesion were not affected. Our results demonstrate that PDPN mediates the invasive properties of cells derived from papillary thyroid carcinomas, suggesting that podoplanin might promote PTC progression. PMID:24797369

    The aim of this retrospective study was to determine the rate of metastases in the central neck compartment and examine the morbidity and rate of recurrence in patients with differentiated thyroid cancer treated with or without a central neck dissection. Two hundred and fifteen patients undergoing total thyroidectomy with preoperative diagnosis of differentiated thyroid cancer, in the absence of suspicious nodes, were divided in two groups: those who underwent a thyroidectomy only (group A; n = 169) and those who also received a central neck dissection (group B; n = 46). Five cases (2.32%) of nodal recurrence were observed: 3 in group A and 2 in group B. Tumor histology was associated with a risk of recurrence: Hürthle cell-variant and tall cell-variant carcinomas were associated with a high risk of recurrence. Multifocality and extrathyroidal invasion also presented a higher risk, while smaller tumors were at lower risk. The results of this study suggest that prophylactic central neck dissection should be reserved for high-risk patients only. A wider use of immunocytochemical and genetic markers to improve preoperative diagnosis and the development of methods for the intraoperative identification of metastatic lymph nodes will be useful in the future for the improved selection of patients for central neck dissections.

    Poorly differentiated gastric adenocarcinoma of solid type is known to show a clinicopathological diversity, but its morphological characteristics have rarely been investigated. In this study, we defined poorly differentiated medullary carcinoma indicating the following three characteristics: (i) more than 90% of the entire tumor were composed of poorly differentiated adenocarcinoma in a medullary growth, (ii) the tumor exhibited an expansive growth at the tumor margin, and (iii) special types such as an α-fetoprotein-producing carcinoma, neuroendocrine carcinoma, and carcinoma with lymphoid stroma were excluded. Based on the definition, we subclassified the poorly differentiated gastric adenocarcinoma of solid type into the two groups: medullary carcinoma and non-medullary carcinoma, and clinicopathologically analyzed 23 cases of medullary carcinomas and 38 cases of non-medullary carcinomas. The medullary carcinomas less frequently displayed lymphatic invasion, venous invasion, and lymph node metastasis, compared with the non-medullary carcinoma (P < 0.001, P = 0.002, and P < 0.001, respectively). The patients with medullary carcinomas significantly showed better disease-free survival (P = 0.017). This is the first study to demonstrate that poorly differentiated adenocarcinoma of solid type can be subclassified into tumors with low and high malignant potentials. Gastric poorly differentiated medullary carcinoma is considered to be a novel histological type predicting good patients' prognosis. PMID:27108877

    Background The impact of varying degrees of extrathyroid extension (ETE), especially microscopic ETE (METE), on survival in thyroid carcinomas (TC) has not been well established. Our objective was to analyze ETE at the molecular and histologic levels and assess the effect of its extent on outcome. Methods All cases of TC with ETE but without nodal metastases at presentation (NMP) were identified over a 20-year period and grouped into gross and METE. Twelve papillary thyroid carcinomas (PTCs) without ETE and NMP were also analyzed. Cases with paraffin tissues were subjected to mass spectrometry genotyping encompassing the most significant oncogenes in TC: 111 mutations in RET, BRAF, NRAS, HRAS, KRAS, PIK3CA, and AKT1, and other related genes were surveyed. Results Eighty-one (10%) of 829 patients in the database had ETE and no NMP. There was a much higher frequency of poorly differentiated and anaplastic carcinomas (12/29, 41%) in patients with gross ETE than in those with METE (3/52, 6%) (p < 0.01). There was a higher disease-specific survival (DSS) in patients with METE than in those with gross ETE (p < 0.0001). Except for an anaplastic case, no recurrences were detected in 45 patients with METE, including 23 PTC patients followed up for a median of 10 years without radioactive iodine therapy. Within patients with gross invasion into trachea/esophagus, tumors with high mitotic activity and/or tumor necrosis correlated with worse DSS (p < 0.05). Fifty-six cases with ETE were genotyped as follows: BRAFV600E, 39 (70%); BRAFV600E-AKT1, 1 (1.8%); NRAS, 1 (1.8%); KRAS, 1 (1.8%); RET/PTC, 3 (5%); wild type, 11 (19.6%). Within PTCs, BRAF positivity rate increased the risk of ETE (p = 0.01). If PTC follicular variants are excluded, BRAF positivity does not correlate with ETE status within classical/tall cell PTC. Conclusion (i) PTCs with METE without NMP have an extremely low recurrence rate in contrast to tumors with gross ETE. (ii) High mitotic activity

    The increased prevalence of BRAF mutations in thyroid carcinoma and primary cutaneous melanoma (PCM) hint that dysregulation of BRAF might contribute to the noted association between PCM and thyroid carcinoma. A recent study evaluating the rate of BRAFV600E mutations among patients who had been diagnosed with primary papillary thyroid carcinoma (PTC) and PCM showed that patients with either PCM or PTC were at an increased risk of developing the other as a second primary malignant neoplasm. Furthermore, the authors noted that samples from patients suffering from both malignancies exhibited a higher rate of incidence of the BRAFV600E mutation, compared with patients not suffering from both malignancies. These studies support the hypothesis that the pathogenesis of these 2 malignancies might share a conserved molecular pattern associated with dysregulation of the BRAF protein. One mechanism through which BRAF might contribute to PCM and thyroid carcinoma progression is through induction of epithelial-mesenchymal transition (EMT). Specifically, the Snail/E-cadherin axis has been demonstrated as a pathway dysregulated by BRAF, leading to EMT in both malignancies. Our analysis focuses on the results of these recent investigations, and through a review of select molecules relevant to EMT, looks to provide a context by which to better understand the relevance and role of stromal-parenchymal signaling and the BRAF mutation in the pathogenesis of PTC and PCM.

    We present a patient with a complex clinical picture of primary hyperparathyroidism with multiple destructive skeletal lesions suspicious of bone metastases and concomitant multifocal papillary thyroid carcinoma with a metastatic central lymph node. He presented with progressively worsening right hip pain and restricted motion. Magnetic resonance imaging revealed multiple lytic lesions involving predominantly the right trochanter minor and the left inferior and posterior pubic rami. Biochemical tests were consistent with primary hyperparathyroidism. Neck ultrasound and parathyroid scintigraphy revealed a single parathyroid adenoma and a thyroid nodule, preoperative cytology of which confirmed papillary thyroid carcinoma, as did the final surgical specimen. Biochemical results, regarding hyperparathyroidism, declined to normal levels and his complaints gradually decreased after surgery. Postoperative whole body bone scintigraphy showed increased tracer uptakes at multiple sites, but they were proved to be metabolically inactive by fluorodeoxyglucose positron emission tomography/computed tomography.

    Differentiation of functional thyroid epithelia from pluripotent stem cells (PSCs) holds the potential for application in regenerative medicine. However, progress toward this goal is hampered by incomplete understanding of the signaling pathways needed for directed differentiation without forced overexpression of exogenous transgenes. Here we use mouse PSCs to identify key conserved roles for BMP and FGF signaling in regulating thyroid lineage specification from foregut endoderm in mouse and Xenopus. Thyroid progenitors derived from mouse PSCs can be matured into thyroid follicular organoids that provide functional secretion of thyroid hormones in vivo and rescue hypothyroid mice after transplantation. Moreover, by stimulating the same pathways, we were also able to derive human thyroid progenitors from normal and disease-specific iPSCs generated from patients with hypothyroidism resulting from NKX2-1 haploinsufficiency. Our studies have therefore uncovered the regulatory mechanisms that underlie early thyroid organogenesis and provide a significant step toward cell-based regenerative therapy for hypothyroidism.

    Thyroid cancer is the fifth most common cancer in women with approximately 60,220 expected new cases in the United States in 2013, and the incidence continues to increase each year. Fortunately, the majority are well-differentiated thyroid cancers with excellent overall prognosis. Controversy persists regarding the optimal surgical management of differentiated thyroid cancer in terms of the extent of thyroid resection (thyroid lobectomy vs total thyroidectomy) and the utility of prophylactic central neck dissection (pCND) in low-risk PTC, and papillary thyroid microcarcinoma (PTMC, defined as <10 mm). Thyroid surgical approaches have progressed from the Kocher open incision to minimally invasive techniques that include endoscopic and robotic thyroidectomy. Overall, these minimally invasive techniques have been shown to be safe, and appear to be associated with improved cosmesis and decreased pain compared to open thyroidectomy. PMID:26504264

    A substantial increase in papillary thyroid carcinoma (PTC) among children exposed to the radioiodine fallout has been one of the main consequences of the Chernobyl reactor accident. Recently, the investigation of PTCs from a cohort of young patients exposed to the post-Chernobyl radioiodine fallout at very young age and a matched nonexposed control group revealed a radiation-specific DNA copy number gain on chromosomal band 7q11.23 and the radiation-associated mRNA overexpression of CLIP2. In this study, we investigated the potential role of CLIP2 as a radiation marker to be used for the individual classification of PTCs into CLIP2-positive and -negative cases-a prerequisite for the integration of CLIP2 into epidemiological modelling of the risk of radiation-induced PTC. We were able to validate the radiation-associated CLIP2 overexpression at the protein level by immunohistochemistry (IHC) followed by relative quantification using digital image analysis software (P=0.0149). Furthermore, we developed a standardized workflow for the determination of CLIP2-positive and -negative cases that combines visual CLIP2 IHC scoring and CLIP2 genomic copy number status. In addition to the discovery cohort (n=33), two independent validation cohorts of PTCs (n=115) were investigated. High sensitivity and specificity rates for all three investigated cohorts were obtained, demonstrating robustness of the developed workflow. To analyse the function of CLIP2 in radiation-associated PTC, the CLIP2 gene regulatory network was reconstructed using global mRNA expression data from PTC patient samples. The genes comprising the first neighbourhood of CLIP2 (BAG2, CHST3, KIF3C, NEURL1, PPIL3 and RGS4) suggest the involvement of CLIP2 in the fundamental carcinogenic processes including apoptosis, mitogen-activated protein kinase signalling and genomic instability. In our study, we successfully developed and independently validated a workflow for the typing of PTC clinical samples into CLIP2

    Differentiated thyroid cancers (DTC) are malignancies of follicular cell derivation. Histopathologically and oncologically, DTC fall into two broad tumor categories: papillary (PTC) and follicular thyroid cancer (FTC). These major tumor categories, based on clinical manifestation and biological behavior, are further subdivided into low-risk [papillary microcarcinoma (mPTC); minimally invasive follicular cancer (MIFTC)] and high-risk DTC [PTC>1 cm or metastatic; MIFTC with histopathological angioinvasion; widely invasive FTC (WIFTC)]. Recently, a surgical approach has been adopted that differentiates between low-risk and high-risk DTC. The rationale behind this new concept is to better balance oncologic risk (high vs low) with the surgical morbidity attendant to the procedure (recurrent laryngeal nerve palsy and hypoparathyroidism). This surgical risk is larger with routine total thyroidectomy (TT) and central node dissection (CND) than with less than TT or TT without CND.Whereas TT with CND remains the treatment of choice for high-risk DTC with metastases, the extent of thyroid resection and lymph node dissection can be reduced in low-risk PTC and FTC without demonstrable loss of oncological benefit. In the new millennium, the surgical approach to DTC, especially low-risk PTC and FTC, has undergone considerable change, resulting in less extensive procedures. This risk-adapted strategy relies not only on the skillful histopathologic detection of multifocality in PTC and vascular invasion in MIFTC, but likewise necessitates diligent follow-up to spot and adequately treat local recurrences and distant metastases as they become clinically apparent.

    In this communication, the authors discuss the issue of individualization of thyrotropin suppressive therapy in differentiated thyroid carcinoma (DTC) patients and share their views with respect to optimizing the dose of levothyroxine (LT) prescription both during discharge from radioiodine therapy ward and during follow-up. The changing management paradigm at our Institute during post-thyroidectomy period and during the preparation for radioiodine scan is also briefly highlighted. Five factors can be identified as important determinants for the dose individualization approach: (1) Persistence or absence of metastatic disease, (2) the risk characteristics of the patient and the tumor (3) patient's clinical profile, symptomatology, and contraindications (4) the feasibility to ensure a proper thyroid stimulating hormone TSH suppression level (depends on patient's socio-economic and educational background, the connectivity with the local physician and his expertise) (5) time period elapsed since initial diagnosis. While discussing each individual case scenario, the authors, based upon their experience in one of the busiest thyroid cancer referral centers in the country, discuss certain unaddressed points in the current guideline recommendations, deviations made and some challenges toward employing them into practice, which could be situation and center specific. In addition to these, the value of clinical examination, patient profile and detailed enquiry about clinical symptomatology by the attending physician in each follow-up visit cannot be overemphasized. According to the authors, this aspect, quite important for dose determination in an individual, is relatively underrepresented in the present guidelines. It would also be worthwhile to follow a conservative approach (till clear data emerges) in patients who have characteristics of “high-risk” disease, but are clinically and biochemically disease free, if no medical contraindications exist and patient

    Childhood papillary thyroid carcinoma is associated with more locally aggressive and more frequent distant disease than its adult counterpart. Recurrence rates tend to be higher in children, but cause-specific mortality remains low. Optimal initial treatment of childhood papillary thyroid carcinoma should include total or near-total thyroidectomy and central compartment node clearance. Modified neck dissections should be performed for biopsy-proven lateral neck disease. Every effort should be made to maintain parathyroid and laryngeal nerve function. Radical neck dissections are to be avoided. Radioiodine remnant ablation (RRA), appropriate thyroid hormone suppressive therapy (THST), and judicious use of therapeutic doses of (131)I are applied to achieve a disease-free status, which is most often confirmed by negative neck ultrasonography, negative whole-body scan (either withdrawal or recombinant human thyroid-stimulating hormone-stimulated), and extremely low levels of serum thyroglobulin. Appropriate utilization of (131)I, THST, repeat surgery, external beam radiotherapy, and rarely chemotherapy may provide long-term palliation and some cures in patients with recurrent/persistent disease. Follow-up should be lifelong, and the care of children after age 17 should subsequently be transferred to adult-care endocrinologists with expertise in managing thyroid neoplasia. Optimal surgical management can be achieved if adequate operations are routinely carried out by "high-volume" thyroid surgeons with expertise in the care of children. Nowhere is a multidisciplinary approach (endocrinologists, surgeons, nuclear medicine physicians, pediatricians, pathologists, oncologists) more critical than in the long-term management of papillary thyroid carcinoma that presents during childhood.

    Objective: The current study aimed to determine the efficacy of radioiodine-131 (131I) ablation therapy with thyroid hormone replacement one day before 131I administration in patients with well-differentiated thyroid cancer (DTC). Methods: This retrospective study included 29 patients who underwent 131I therapies twice for DTC during 6-12 months. Since all the patients obviously had residual lesions by their serum thyroglobulin levels or their scintigrams at the first therapies, they underwent the second 131I therapies without diagnostic scintigraphy after the first therapies. After confirming the sufficient elevation of TSH concentration, thyroid hormone replacement was resumed one day before 131I administration (3.7-7.4GBq). The ablation rate of thyroid remnant at the first 131I therapy was evaluated by comparing 131I post-therapeutic images of the two treatments. Results: Three patients were administrated thyroid hormone after 131I therapy because of insufficient TSH concentration under thyroid hormone withdrawal. In the remaining 26 patients, 41 thyroid remnant accumulations were detected in all 26 patients at the first 131I therapy. Based on the second 131I post-therapeutic images, successful ablation was confirmed in 24 of 26 patients (92.3%) and 38 of 41 sites (92.7%), which was comparable with historically reported ablation rates. Conclusion: Thyroid hormone replacement one day before 131I therapy could provide a sufficiently high ablation rate in patients with DTC.

  7. Risk Stratification in Differentiated Thyroid Cancer: An Ongoing Process

    PubMed Central

    2016-01-01

    Thyroid cancer is an increasingly common malignancy, with a rapidly rising prevalence worldwide. The social and economic ramifications of the increase in thyroid cancer are multiple. Though mortality from thyroid cancer is low, and most patients will do well, the risk of recurrence is not insignificant, up to 30%. Therefore, it is important to accurately identify those patients who are more or less likely to be burdened by their disease over years and tailor their treatment plan accordingly. The goal of risk stratification is to do just that. The risk stratification process generally starts postoperatively with histopathologic staging, based on the AJCC/UICC staging system as well as others designed to predict mortality. These do not, however, accurately assess the risk of recurrence/persistence. Patients initially considered to be at high risk may ultimately do very well yet be burdened by frequent unnecessary monitoring. Conversely, patients initially thought to be low risk, may not respond to their initial treatment as expected and, if left unmonitored, may have higher morbidity. The concept of risk-adaptive management has been adopted, with an understanding that risk stratification for differentiated thyroid cancer is dynamic and ongoing. A multitude of variables not included in AJCC/UICC staging are used initially to classify patients as low, intermediate, or high risk for recurrence. Over the course of time, a response-to-therapy variable is incorporated, and patients essentially undergo continuous risk stratification. Additional tools such as biochemical markers, genetic mutations, and molecular markers have been added to this complex risk stratification process such that this is essentially a continuum of risk. In recent years, additional considerations have been discussed with a suggestion of pre-operative risk stratification based on certain clinical and/or biologic characteristics.

    Primary mucoepidermoid carcinoma (MEC) of the thyroid and columnar cell variant of papillary carcinoma of the thyroid (PCT) are uncommon neoplasms. We report the first case of composite MEC and columnar cell variant of PCT. An 86-year-old man consulted for a 47-mm thyroid nodule, cytologically compatible with PCT. Total thyroidectomy was performed. Histological diagnosis, with support of histochemistry and immunohistochemistry, was mixed primary carcinoma of the thyroid, associating an MEC component with predominantly columnar cell variant of PCT. Sixteen months after surgery and external beam radiation therapy, the patient was free of recurrence or distant metastasis. This case report offers an opportunity to highlight the potential pitfalls concerning the interpretation of mucin histochemistry in thyroid tumors. PMID:26755714

    Objective This study investigated clinical and pathological characteristics and risk factors in papillary thyroid carcinoma (PTC) patients’ native to Yunnan plateau in southwestern China. Methods Clinical data from 1,198 patients diagnosed with PTC (n=578) and control subjects (n=620) with benign thyroid disease (ie, thyroid nodule disease, benign thyroid diseases [BTD]) in Yunnan province were analyzed retrospectively. Results The mean patient age was lower for PTC than for BTD. Positive ratios of thyroid peroxidase antibody, thyroglobulin antibody (TGAb), and thyrotrophin receptor antibody (TRAb) were higher in PTC than in BTD patients. The ratio of PTC coexisting with Hashimoto’s thyroiditis (HT) or with lymphocytic thyroiditis was higher than that of BTD. The number of patients whose age at menarche was ≤13 years, who had given birth to less than or equal to two children, or who were in premenopause were higher in the PTC than in the BTD group. Multivariate conditional logistic regression analyses revealed that age >45 years, nodal size >1 cm, and elevated TG levels were protective factors against PTC. Abnormally elevated TGAb and TRAb levels were independent risk factors for PTC in females. Conclusion HT was not an independent risk factor for but was associated with PTC. TRAb is a risk factor for PTC in individuals living in the Yunnan plateau, but not for those in the plains region. PMID:27418831

    Papillary thyroid carcinoma (PTC) is the commonest thyroid malignancy worldwide for which the radiation exposure is the most influential risk factor. The levels of oxidative stress in PTC are not well characterized on the tissue level. The objective of this study was to evaluate total oxidant status (TOS) and total antioxidant status (TAS) in PTC and benign goiter (BG) tissues and to examine their association with clinicopathological characteristics. Tumor and normal thyroid tissue samples were collected from 59 PTC patients, and goiter tissues were collected from 50 BG patients. TOS and TAS were quantified in the tissue homogenates by spectrophotometric assays. TOS values in tumor tissues did not differ significantly from normal and goiter tissues; however, PTC tissues have significantly higher TAS values than normal and goiter tissues. TOS values correlated with retrosternal growth in BG patients. The significant correlations were found between TOS and TAS values and thyroid function parameters. In 17 PTC patients with multiple tumor foci (multicentric phenotype), TAS values were significantly lower, compared to 42 patients with unicentric PTC. TAS and TOS are the most useful predictors of thyroid capsular invasion by PTC. The age, sex, body mass index, smoking, familial history of thyroid disease and nodule size did not influence TOS and TAS in PTC or BG patients. In conclusion, we show the profiles of TOS and TAS in PTC and BG tissues. Importantly, PTC tissues possess increased antioxidant capacity. The redox status influences the parameters of the thyroid function and tumor's biological behavior. PMID:27615359

    A previous study on papillary thyroid carcinomas (PTC) in young patients who were exposed to 131iodine from the Chernobyl fallout revealed an exclusive gain of chromosomal band 7q11.23 in exposed cases compared to an age-matched control cohort. CLIP2, a gene located within band 7q11.23 was shown to be differentially expressed between exposed and non-exposed cases at messenger RNA and protein level. Therefore, a standardized procedure for CLIP2 typing of PTCs has been developed in a follow-up study. Here we used CLIP2 typing data on 117 post-Chernobyl PTCs from two cohorts of exposed patients with individual dose estimates and 24 non-exposed controls to investigate a possible quantitative dose-response relationship of the CLIP2 marker. The ‘Genrisk-T’ cohort consisted of 45 PTCs and the ‘UkrAm’ cohort of 72 PTCs. Both cohorts differed in mean dose (0.59 Gy Genrisk-T, 1.2 Gy UkrAm) and mean age at exposure (AaE) (2 years Genrisk-T, 8 years UkrAm), whilst the median latency (16 years Genrisk-T, 18 years UkrAm) was comparable. We analyzed the association between the binary CLIP2 typing and continuous thyroid dose with logistic regression. A clear positive dose-response relationship was found for young PTC cases [age at operation (AaO) < 20 years, AaE < 5 years]. In the elder age group a higher proportion of sporadic tumors is assumed due to a negligible dose response, suggesting different molecular mechanisms in sporadic and radiation-induced cases. This is further supported by the association of elder patients (AaO > 20 years) with positivity for BRAF V600E mutation. PMID:25957251

    Background Through a transcriptome microarray analysis, we have isolated Anterior gradient protein 2 (AGR2) as a gene up-regulated in papillary thyroid carcinoma (PTC). AGR2 is a disulfide isomerase over-expressed in several human carcinomas and recently linked to endoplasmic reticulum (ER) stress. Here, we analyzed the expression of AGR2 in PTC and its functional role. Methods Expression of AGR2 was studied by immunohistochemistry and real time PCR in normal thyroids and in PTC samples. The function of AGR2 was studied by knockdown in PTC cells and by ectopic expression in non-transformed thyroid cells. The role of AGR2 in the ER stress was analyzed upon treatment of cells, expressing or not AGR2, with Bortezomib and analyzing by Western blot the expression levels of GADD153. Results PTC over-expressed AGR2 at mRNA and protein levels. Knockdown of AGR2 in PTC cells induced apoptosis and decreased migration and invasion. Ectopic expression of AGR2 in non-transformed human thyroid cells increased migration and invasion and protected cells from ER stress induced by Bortezomib. Conclusions AGR2 is a novel marker of PTC and plays a role in thyroid cancer cell survival, migration, invasion and protection from ER stress. PMID:24976026

    Anaplastic thyroid carcinoma (ATC) is the most lethal form of thyroid neoplasia and represents the end stage of thyroid tumor progression. No effective treatment exists so far. ATC frequently derive from papillary thyroid carcinomas (PTC), which have a good prognosis. In this study, we analyzed the mRNA expression profiles of 59 thyroid tumors (11 ATC and 48 PTC) by microarrays. ATC and PTC showed largely overlapping mRNA expression profiles with most genes regulated in all ATC being also regulated in several PTC. 43% of the probes regulated in all the PTC are similarly regulated in all ATC. Many genes modulations observed in PTC are amplified in ATC. This illustrates the fact that ATC mostly derived from PTC. A molecular signature of aggressiveness composed of 9 genes clearly separates the two tumors. Moreover, this study demonstrates gene regulations corresponding to the ATC or PTC phenotypes like inflammatory reaction, epithelial to mesenchymal transition (EMT) and invasion, high proliferation rate, dedifferentiation, calcification and fibrosis processes, high glucose metabolism and glycolysis, lactate generation and chemoresistance. The main qualitative differences between the two tumor types bear on the much stronger EMT, dedifferentiation and glycolytic phenotypes showed by the ATC. PMID:23115614

    Distant metastases are more common in follicular thyroid carcinoma (FC) than in papillary thyroid carcinoma. However, FC metastasis to the kidney with eggshell calcification, as observed in the present case, is rare. The current report presents a case of a 67-year-old woman exhibiting a solitary tumor in the mid pole of the left kidney. Radical nephrectomy was performed, as the tumor was diagnosed as a primary renal carcinoma using contrast-enhanced computed tomography. Once the tumor was confirmed to be FC, total thyroidectomy was performed. Following administration of an oral therapeutic dose of 100 mCi 131I, functional imaging demonstrated the presence of multifocal metastases in the chest and abdomen. Euthyrox® was prescribed orally to aid normal thyroid function. Follow-up 6 months later using radionuclide imaging demonstrated the disappearance of the multifocal metastases in the chest and abdomen. The distant metastasis of FC may represent the initial symptom of the primary lesion, which was neglected. Ultrasound is an effective method to examine nodules located on the thyroid. PMID:27123105

    Embryonic develop-associated gene 1 (EDAG-1), a hematopoietic tissue-specific protein, is usually highly expressed in the placenta, fetal liver, bone marrow and leukemia cells, but the expression status in normal or solid tumor tissues is rarely reported. In this study, we found that EDAG-1 was up-regulated in thyroid carcinoma tissues and cells. Knockdown of EDAG-1 suppressed proliferation and enhanced cisplatin-induced apoptosis of thyroid carcinoma cells. We also demonstrated that knockdown of EDAG-1 inactivated the phosphatidylinositol-3 kinase (PI3K)/Akt signaling pathway in vitro and in vivo. Moreover, knockdown of EDAG-1 suppressed tumorigenesis of thyroid carcinoma in vivo. Taken together, these results suggest that EDAG-1 regulates the proliferation and apoptosis of thyroid carcinoma via the PI3K/Akt signaling pathway. PMID:27261581

    The objective of the present study was to compare the effects of isotretinoin 9-cis (RA9-cis) as a post-surgery treatment of thyroid carcinoma to a traditional treatment (doxorubicin) and no treatment. Owners who did not want their dogs to receive treatment were placed into the control group A (GA; n=10). The remaining dogs were randomly placed into either group B (GB; n=12) and received doxorubicin at a dose of 30 mg/m2 every three weeks, for six complete cycles or group C (GC; n=15) and treated with RA9-cis at a dose of 2 mg/kg/day for 6 months. The time of the recurrence was significantly shorter in the GA and GB compared to GC (P=0.0007; P=0.0015 respectively), while we did not detect differences between GA and GB. The hazard ratio of recurrence between GA and GB compared to GC were 7.25 and 5.60 times shorter, respectively. We did not detect any differences between the other groups. The risk ratio of recurrence was 2.0 times higher in GA compared to GC and 2.1 times higher in GB compared to GC. The type of carcinoma had an effect on time of survival with follicular carcinomas having an increased mean survival time than follicular-compact carcinomas (P<0.0001) and follicular-compact carcinomas had a longer mean survival time than compact carcinomas. The interaction among treatment and type was significant, but survival time in follicular carcinomas did not differ between treatments. In follicular-compact carcinomas the survival time of GC was greater than GB (P<0.05), but we did not detect a difference between GA and GB. In conclusion, this study shows that the use of surgery in combination with RA9-cis treatment significantly increases survival rate and decreases the time to tumor recurrence when compared to doxorubicin treated or untreated dogs. The histological type of carcinoma interacted with treatment for time to recurrence and survival time, with more undifferentiated carcinomas having a worse prognosis than differentiated carcinomas.

    PAX8 is a thyroid-specific transcription factor whose expression is dysregulated in thyroid cancer. A recent study using a conditional knock-out mouse model identified 58 putative PAX8 target genes. In the present study, we evaluated the expression of 11 of these genes in normal and tumoral thyroid tissues from patients with papillary thyroid cancer (PTC). ATP1B1, GPC3, KCNIP3, and PRLR transcript levels in tumor tissues were significantly lower in PTCs than in NT, whereas LCN2, LGALS1 and SCD1 expression was upregulated in PTC compared with NT. Principal component analysis of the expression of the most markedly dysregulated PAX8 target genes was able to discriminate between PTC and NT. Immunohistochemistry was used to assess levels of proteins encoded by the two most dyregulated PAX8 target genes, LCN2 and GPC3. Interestingly, GPC3 was detectable in all of the NT samples but none of the PTC samples. Collectively, these findings point to significant PTC-associated dysregulation of several PAX8 target genes, supporting the notion that PAX8-regulated molecular cascades play important roles during thyroid tumorigenesis.

    Introduction. Navarra has the highest incidence of differentiated thyroid cancer in Spain. The aim of this study was to review its management carried out by the Navarra's multidisciplinary Thyroid Disease Unit, from 1987 to 2003. Material and Methods. 325 patients were studied to find the incidence, prevalence, and prognostic factors. Statistical analysis comprised univariate and multivariate Cox proportional hazards regression models for survival and tumor recurrence. Results. The average annual incidence was 3.6 per 100,000 inhabitants, with a final prevalence of 82.4 per 100,000. Regarding survival and recurrence, statistical significance was observed for stage IV, follicular carcinoma, capsular and prethyroid muscles invasion, and T4 group. Only survival was related to tumour size larger than 40 mm. Only recurrence was related to lymph node metastases and radioiodine dose higher than 100 mCi. Conclusions. Attendance of patients in a functional unit setting has allowed us to classify them into three risk groups. PMID:22084734

    Neck ultrasonography (US) is recommended for the assessment of all patients with thyroid carcinoma after initial therapy, since even low-risk patients with undetectable stimulated thyroglobulin (Tg) may present cervical metastases. In the case of these metastases, US is the most sensitive method and is superior to whole-body 131I scanning. Cervical lymph nodes with a diameter > 5 mm presenting thin calcifications and/or cystic degeneration have almost always a malignant etiology. In the absence of these characteristics, a round shape and the absence of an echogenic hilum are "suspicious" findings, whereas elongated lymph nodes with a visible echogenic hilum are considered benign. Doppler flow analysis helps with the differential diagnosis, usually revealing peripheral or mixed hypervascularization in malignant cases. In the presence of "suspicious" lymph nodes upon US, fine-needle aspiration cytology and measurement of Tg in the needle lavage fluid are useful and complementary exams for the definition of the etiology, with the combination of the two methods showing elevated sensitivity and 100% specificity. US is also useful before thyroidectomy, even contributing in some cases to modify the surgical planning, and before ablation for the measurement of thyroid remnants and detection of persistent lymph node metastases. Another application of this imaging method is to guide the injection of ethanol (sclerotherapy) or the introduction of electrodes for radiofrequency ablation in selected cases of isolated lymph node metastases as an alternative to traditional therapies.

    Thyroid-like follicular carcinoma of the kidney (TLFCK) is an extremely rare subtype of renal cell carcinoma with close resemblance to the well-differentiated thyroid follicular neoplasms. TLFCK has not been included in the 2004 World Health Organization (WHO) classification due to the limited data available. Only 27 cases have been reported in the literature to date. Herein, we report a unique case of TLFCK that presented as a striking skull and meningeal metastasis 5 years after the initial diagnosis; this is the first case of TLFCK with such a novel metastasis pattern. A 68-year-old woman was found to have a right renal lesion using computed tomography (CT) during her regular clinical follow-up visit for bladder cancer, but she exhibited no obvious clinical symptoms. The CT scan showed a 4.4-cm diameter, slightly lobulated soft tissue mass in the right lower kidney, the pathological findings of which showed a TLFCK. Five years later, the patient had progressed to skull and meningeal metastasis. Both the renal tumor and the metastasis lesion were composed almost entirely of follicles with a dense, colloid-like material that resembled thyroid follicular carcinoma. However, no lesion was found in the thyroid gland. The neoplastic epithelial cells were strongly immunoreactive for cytokeratin 7 (and vimentin but negative for thyroid transcription factor-1 and thyroglobulin. This is the first reported case of TLFCK to consist of widespread metastases to the skull and meninges and provides evidence that this rare variant of renal cell carcinoma has uncertain malignant potential and can be more clinically aggressive than previously believed.

    Long noncoding RNA (lncRNA) is a kind of RNA that is longer than 200 nucleotides with limited or no protein-coding potential. Studies have proved that lncRNAs play important regulatory roles in gene expression and contribute to oncogenesis and cancer metastasis. However, the expression level of lncRNAs and their clinicopathologic significance in papillary thyroid carcinoma (PTC) have not been well studied. In this study, we investigated the expression level of a novel lncRNA NONHSAT037832 in PTC and paired noncancerous thyroid tissues as well as some cell lines by quantitative real-time polymerase chain reaction. The association between the expression level of NONHSAT037832 and clinicopathologic characteristics of patients with PTC was further analyzed. Three receiver operating characteristic curves (ROCs) were established to evaluate the diagnostic value of NONHSAT037832. The results suggested that the expression level of NONHSAT037832 was significantly decreased in PTC compared with paired noncancerous tissues (P < 0.01). And, NONHSAT037832 was also significantly downregulated in two PTC cell lines (K1 and IHH-4) compared to normal thyroid follicular epithelial cell line Nthy-ori 3-1 (P < 0.01). Downregulated NONHSAT037832 was significantly associated with lymph node metastasis (P = 0.015) and tumor size (P = 0.032). The ROCs revealed that NONHSAT037832 had a high diagnostic value for differentiating between PTC and noncancerous diseases as well as identifying PTC with lymph node metastasis and larger tumors (≥3 cm). The area under curve was up to 0.897 (95%CI = 0.852-0.942, P = 0.000), 0.641 (95%CI = 0.519-0.762, P = 0.033), and 0.702 (95%CI = 0.567-0.827, P = 0.008), respectively. This study indicated that NONHSAT037832 might serve as a potential biomarker of PTC. PMID:26611646

    The value of Tc HYNIC-TOC scintigraphy clarifying skeletal and hepatic-predominant metastatic disease in a 55-year-old woman (diagnosed earlier to have papillary carcinoma thyroid and had undergone total thyroidectomy and radioiodine ablation) is illustrated. The whole-body radioiodine scan and battery of serum tumor markers were normal. Multiple metastatic foci in the liver and skeleton were Tc HYNIC-TOC avid. Serum chromogranin A level was substantially elevated (1771.60 ng/mL). This represents an unusual alternative diagnosis signified by a highly positive scan in the setting of apparent non-iodine-concentrating metastatic disease in a patient of differentiated thyroid carcinoma.

    Adenoid cystic carcinoma (ACC) is a rare malignant tumor, reportedly representing <1% of all head and neck cancers. There have been few reported cases of ACC of the upper airway presenting as a midline mass. This is the case report of a 47-year-old female patient who presented with such a midline neck mass. The mass was approached and investigated as a thyroid mass, but was ultimately found to be a tracheal tumor with thyroid invasion. We herein discuss in detail the patient history, investigation and treatment.

    We report the case of a 72-year-old man who presented with non-producing multiple myeloma (MM) with three additional concomitant solid tumors that were identified by postmortem autopsy. The disease was refractory to anti-MM therapy including bortezomib and lenalidomide, and he finally died of bacterial pneumonia with diffuse alveolar damage 8 months after the diagnosis. An autopsy revealed that he was also affected by three other solid cancers, cholangiocellular carcinoma, medullary thyroid cancer and papillary thyroid cancer that were clinically asymptomatic and remained undiagnosed before death. A review of the literature suggests that primary quadruple cancers including MM are extremely rare. PMID:27150876

    The clinical and histologic features of thyroid carcinoma in raccoon dogs have not been previously reported. Three of four raccoon dogs (Nyctereutes procyonoides) over 8 yr of age at the Nogeyama Zoological Gardens developed thyroid follicular cell carcinomas that were detected at necropsy. The affected raccoon dogs were rescued from the wild and were housed at the Nogeyama Zoological Gardens for 8 yr 8 mo, 8 yr 10 mo, and 10 yr 3 mo, respectively. Although all of them appeared lethargic and developed partial alopecia or desquamation of their skin, they did not display any other specific clinical signs associated with a thyroid lesion. Serum thyroid hormone values were examined in two of the affected raccoon dogs and the average and standard deviation values (free-thyroxin [FT4]: 0.078 ± 0.077 pM/L and 0.062 ± 0.0039 pM/L; free-triiodothyronine [FT3]: 3.261 ± 0.765 pM/L and 3.407 ± 0.919 pM/L) were lower than the reference range (FT4: 0.141 ± 0.117 pM/L; FT3: 5.139 ± 2.412 pM/L) derived from a clinically normal raccoon dog. On necropsy, the thyroid lobes were markedly enlarged bilaterally. Histopathologically, the neoplastic cells in the thyroid gland appeared round or oval and columnar or cuboidal with minimal heteromorphism. Moreover, mostly small (but occasionally large) follicles were identified, and the neoplastic cells had infiltrated into the surrounding capsule and blood vessels. The histopathologic features of the thyroid tumors in the raccoon dogs revealed that the tumors were derived from follicular cells. PMID:26667546

    Long noncoding RNAs (lncRNAs) have emerged as key regulatory molecules at almost every level of gene expression regulation. The altered expression of lncRNAs is a characteristic of numerous types of cancer, and lncRNAs have been demonstrated to promote the development, invasion and metastasis of tumors through various mechanisms. However, the role of lncRNAs in papillary thyroid carcinoma (PTC) remain unclear. In the present study, differentially expressed lncRNAs and mRNAs were detected by human lncRNA microarray in three pairs of PTC and adjacent noncancerous samples. The microarray results revealed that 675 lncRNAs and 751 mRNAs were abnormally expressed in the three PTC samples compared with adjacent noncancerous samples (fold change ≥2.0; P<0.05). To validate the microarray results, 8 differentially expressed lncRNAs were randomly selected for quantitative polymerase chain reaction (qPCR). The results of qPCR were consistent with the microarray data; the 8 lncRNAs had an aberrant expression in the PTC samples compared with the adjacent noncancerous samples. Gene ontology and pathway analysis indicated that there were 7 downregulated pathways and 29 upregulated pathways in PTC. LncRNA classification and subgroup analysis revealed 7 pairs of enhancer-like lncRNA-mRNA, 9 pairs of antisense lncRNA-mRNA and 45 pairs of lncRNA-mRNA were differentially expressed between PTC and their paired noncancerous samples. In conclusion, the present study identified a series of novel PTC-associated lncRNAs. Further study with these lncRNAs is instrumental for the identification of novel target molecules that could lead to improved diagnosis and treatment for PTC. PMID:27347178

    Thyroid cancer in ovarian teratoma is reported to be rare and experiences are limited. A 26-year-old woman had undergone bilateral cystectomy and omentectomy for bilateral cystic adnexial masses. Pathological examination showed 1.5 cm follicular variant papillary thyroid carcinoma on the basis of unilateral mature cystic teratoma. Increased CA-125 and CA19-9 levels decreased to normal reference ranges after surgery, but postoperative magnetic resonance imaging indicated multiple abdominal cystic loci. After total thyroidectomy, high dose I-131 was administered to ablate thyroid tissue. Thereafter, levothyroxine was started to achieve subclinical hyperthyroidism. No iodine uptake was detected in post-therapeutic whole body scan (WBS) other than thyroid bed. This finding supported that tumor did not show dissemination to abdomen. No uptake on the first-year evaluation with low-dose I-131 WBS suggested the complete ablation of the thyroid gland. It is recommended that thyroid carcinoma arising from ectopic thyroid tissue in a teratoma should be managed as thyroid carcinoma in thyroid. However, direct dissemination to contiguous regions in abdomen and hematogenous dissemination to distant organs should be in mind. Radical surgery including total abdominal hysterectomy, bilateral salphingo-oopherectomy, pelvic and paraaortic lymph node excision and thyroidectomy is recommended. Fertility preserving surgery may be the surgical procedure as in the present case. PMID:23772787

    In oncology, the early cancer detection is recognized as associated with good patient's prognosis. Then, one could expect that differentiated thyroid carcinoma (DTC) undergone fine-needle aspiration cytology (FNA) early have better outcome. Aim of this study was to investigate if DTC prognosis is improved by early FNA diagnosis. DTCs followed-up at our institution were included. Information about initial management of thyroid lesion, FNA, surgery, and postoperative follow-up was collected. Cytologies were classified according to British Thyroid Association (BTA). The final series comprised 219 DTCs, of which 22 (10%) recurred. The length of time between nodule appearance and cancer treatment was significantly (p<0.0001) shorter in patients who had undergone FNA than those who had not. In the FNA group, 73 patients underwent biopsy within six months, 25 at 7-12 months, and 43 after at least one year. Regardless of this highly significant (p<0.0001) difference, the results of TNM staging and cancer recurrence rate were no different between these three subgroups. This result was confirmed in DTCs larger than 1 cm submitted to FNA within 12 months or later. When we evaluated the impact of nodule's presentation on DTC outcome, clinically discovered cancers were significantly associated with relapse (OR 2.81) and advanced TNM stages (p=0.03). These data show a lack of clinical impact of the delayed diagnosis of DTC. Also, the postoperative outcome of these patients should not be influenced by the timing of FNA. Instead, DTC patients with preoperative clinical nodule appearance should be considered at higher risk of relapse. PMID:26821685

    Context There has been a marked increase in the detection of differentiated thyroid carcinoma (DTC) over the past few years, which has improved the prognosis. However, it is necessary to adjust treatment and monitoring strategies relative to the risk of an unfavourable disease course. Materials and Methods This retrospective study examined data from 916 patients with DTC who received treatment at a single centre between 2000 and 2013. The utility of the American Thyroid Association (ATA) and the European Thyroid Association (ETA) recommended systems for early assessment of the risk of recurrent/persistent disease was compared with that of the recently recommended delayed risk stratification (DRS) system. Results The PPV and NPV for the ATA (24.59% and 95.42%, respectively) and ETA (24.28% and 95.68%, respectively) were significantly lower than those for the DRS (56.76% and 98.5%, respectively) (p<0.0001). The proportion of variance for predicting the final outcome was 15.8% for ATA, 16.1% for ETA and 56.7% for the DRS. Recurrent disease was rare (1% of patients), and was nearly always identified in patients at intermediate/high risk according to the initial stratification (9/10 cases). Conclusions The DRS showed a better correlation with the risk of persistent disease than the early stratification systems and allows personalisation of follow-up. If clinicians plan to alter the intensity of surveillance, patients at intermediate/high risk according to the early stratification systems should remain within the specialized centers; however, low risk patients can be referred to endocrinologists or other appropriate practitioners for long-term follow-up, as these patients remained at low risk after risk re-stratification.

    The present study aimed to report the shear wave elastography (SWE) findings in a patient with the diffuse sclerosing variant of papillary thyroid carcinoma (DSVPTC). Since patients with DSVPTC may present with typical clinicopathological features and initially appear to have Hashimoto's thyroiditis, a thorough clinical evaluation and an early diagnosis are important. A 20-year-old female patient presented with a 1-month history of a neck mass and sore throat. Conventional ultrasound and SWE were performed using an AIXPLORER system with 14-5 MHz linear transducer. The patient had undergone total thyroidectomy and bilateral neck lymph node dissection, and an intraoperative pathology consultation to confirm the malignancy of lymph node metastasis. Pathological diagnosis was DSVPTC in both lobes, with lymph node metastases in the bilateral neck. The clinical presentation and serological findings were all indicative of Hashimoto's thyroiditis. Thyroid ultrasonography revealed diffuse enlargement of the both lobes, heterogenous echogenicity without mass formation, diffuse scattered microcalcifications and poor vascularization. SWE revealed stiff values of the thyroid: The mean stiffness was 99.7 kpa, the minimum stiffness was 59.1 kpa and the maximum stiffness was 180.1 kpa. The maximum stiffness of the DSVPTC (180.1 kpa) was higher compared with the diagnostic criteria of malignant thyroid nodules (65 kPa). SWE may be considered as a novel and valuable method to diagnose DSVPC.

    Radioactive iodine (131I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB131I) after 131I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine (131I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each 131I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis. PMID:2926718

    With improvements in the survival rates after childhood cancer, many clinicians have turned their attention to reporting on late effects, and how they might be prevented or treated. In childhood the thyroid gland is especially vulnerable to the carcinogenic action of ionizing radiation. This retrospective study focused on secondary thyroid cancers seen at our institution over more than 30 years (between 1980 and 2012) in patients treated for other malignancies in pediatric age. 36 patients were identified. In most cases, the primary cancer had been Hodgkin disease, and all the patients had been administered radiotherapy for their first malignancy. The secondary thyroid cancers were treated with total thyroidectomy in 27 cases (six with lymphadenectomy), and hemithyroidectomy in nine (one with lymphadenectomy). 12 Patients were also given radiometabolic therapy. All but two had TSH suppression therapy. The histological diagnoses were: 31 papillary and five follicular carcinomas. At 5 and 10 years, the OS was 100 and 95 %, respectively, and the PFS was 96 and 83 %. None of the patients died of their thyroid disease. Nodal involvement at onset was the only factor correlating with recurrence. Surgical sequelae only occurred in patients who underwent total thyroidectomy. Survival in these patients did not depend on the extent of surgery on the thyroid parenchyma. Our data confirm a good prognosis for secondary thyroid cancer, prompting us to encourage a minimalist approach to the treatment of these particular patients wherever possible. PMID:25015396

    Hypothyroidism is a very common hormonal deficiency and the stem cell technology which developed in the recent years may offer a therapeutic strategy for treating this disorder. Hypoxia has been demonstrated to play an important role in embryonic formation and development and to modulate stem cell differentiation. However, the influence of oxygen tension on thyroid differentiation has not been studied. In this study, we used murine induced pluripotent stem (iPS) cells for thyroid cell differentiation under normoxic and hypoxic conditions and compared differentiation efficiency in morphology, function, gene and protein expression under both conditions. We found that hypoxia promoted adhesion and outgrowth of embryoid bodies (EBs) derived from murine iPS cells. Expression of endodermal markers (Foxa2 and Gata4) and thyroid transcription factors (Pax8 and Nkx2.1) was increased by hypoxia at both gene and protein levels during early-mid differentiation stages (p<0.05). And so were the thyroid specific markers NIS and TSHR at the end of the experiment (p<0.05). In addition, functional iodide uptake by differentiated cells was also increased after hypoxia. Thyroid differentiation from iPS cells is enhanced under hypoxia and this may involve hypoxia inducible factors (HIFs) and their downstream gene FGF2. Our data offer a foundation for understanding thyroid development and provide a potentially more efficient way to use cell therapy for treating thyroid deficiency. PMID:27389981

    Our purpose was to evaluate the feasibility of using ultrasonographic criteria of thyroid capsular continuity and tumor contour to differentiate macroscopic extra-thyroidal extension (ETE) from microscopic ETE, as well as non-ETE from ETE. On ultrasonography, we evaluated thyroid capsular continuity (C0 = continuous, C1 = discontinuous, C2 = invisible), and thyroid tumor contour (P0 = in normal parenchyma, P1 = abutting, P2 = bulging), which were grouped into type 1-9 classifications. Either C1-2 or P1-2 was more prevalent in ETE than non-ETE. C1 and P2 tended to be associated with macroscopic ETE, whereas C0 and P1 were significantly associated with microscopic ETE. Types 6, 8 and 9 were more likely to have ETE than non-ETE; type 6 (C1 P2) and type 9 (C2 P2) were significantly associated with macroscopic ETE, whereas type 8 (C2 P1) was associated more with microscopic ETE. Macroscopic and microscopic ETE, as well as non-ETE and ETE, can be differentiated using these pre-operative ultrasonographic criteria. PMID:27471119

    Bowen's disease (BD)/carcinoma is a type of squamous cell carcinoma of the skin, however, the possibility of adnexal differentiation (the development of sebaceous carcinoma or porocarcinoma) occurring in BD/carcinoma has been suggested. We herein describe a case of BD with superficial invasive carcinoma, which showed a clear cell focus, demonstrating tricholemmal differentiation. This clear cell focus showed the following findings: primarily composed of clear cells, somewhat columnar clear cells aligned in a palisade along a discernible basement membrane, tricholemmal keratinization and glycogen contained within the cells. In addition, the immunohistochemical profile in this clear cell focus, namely, negative staining for cytokeratin (CK)1 and positive staining for CK17 and calretinin in the inner cells of the neoplastic lobule, corresponded to that of the outer root sheath cells. This case suggested that adnexal differentiation can rarely occur within true BD/carcinoma, although adnexal carcinomas are commonly associated with a simple bowenoid change. PMID:26365015

  2. Thyroid Growth and Cancer.

    It is proposed that most papillary thyroid cancers originate in infancy and childhood, based on the early rise in sporadic thyroid carcinoma incidence, the pattern of radiation-induced risk (highest in those exposed as infants), and the high prevalence of sporadic papillary thyroid cancers in children and adolescents (ultrasound screening after the Fukushima accident). The early origin can be linked to the growth pattern of follicular cells, with a high mitotic rate in infancy falling to very low replacement levels in adult life. The cell of origin of thyroid cancers, the differentiated follicular cell, has a limited growth potential. Unlike cancers originating in stem cells, loss of the usually tight link between differentiation and replicative senescence is required for immortalisation. It is suggested that this loss distinguishes larger clinically significant papillary thyroid cancers from micro-papillary thyroid cancers of little clinical significance. Papillary carcinogenesis can then be divided into 3 stages: (1) initiation, the first mutation in the carcinogenic cascade, for radiation-induced papillary thyroid cancers usually a RET rearrangement, (2) progression, acquisition of the additional mutations needed for low-grade malignancy, and (3) escape, further mutations giving immortality and a higher net growth rate. Most papillary thyroid cancers will not have achieved full immortality by adulthood, and remain as so-called micro-carcinomas with a very low growth rate. The use of the term 'cancer' to describe micro-papillary thyroid cancers in older patients encourages overtreatment and alarms patients. Invasive papillary thyroid tumours show a spectrum of malignancy, which at its lowest poses no threat to life. The treatment protocols and nomenclature for small papillary carcinomas need to be reconsidered in the light of the new evidence available, the continuing discovery of smaller lesions, and the model of thyroid carcinogenesis proposed.

    The number of new cases of thyroid cancer are dramatically increasing as incidences of this cancer have more than doubled since the early 1970s. Tall cell variant (TCV-PTC) papillary thyroid carcinoma is one type of thyroid cancer that is more aggressive and usually associated with higher local recurrence and distant metastasis. This variant can be identified through visual characteristics of cells in histological images. Thus, we created a fully automatic algorithm that is able to segment cells using a multi-stage approach. Our method learns the statistical characteristics of nuclei and cells during the segmentation process and utilizes this information for a more accurate result. Furthermore, we are able to analyze the detected regions and extract characteristic cell data that can be used to assist in clinical diagnosis.

    Radiation treatment of Long-Evans male rats (40 mu Ci Na131I at the age of 2 months) led to a high incidence of thyroid follicular carcinomas at the age of 24 months; castration of males before irradiation caused a significant reduction in incidence of this tumor. In this study, replacement testosterone (T) was administered to castrated male rats by means of implanted, slow-release hormone-containing pellets (T-physiologic dose). Three testosterone doses (0.1T, 1.0T, and 30T) were used to treat groups of castrated irradiated and castrated nonirradiated rats from 2 to 18 months of age. The incidence of thyroid follicular carcinoma at 18 months in irradiated rats depended on the dose of replacement testosterone used. Tumor incidence was 8%, 14%, 41%, and 50% after treatment with 0T, 0.1T, 1.0T, and 30T, respectively. The incidence of thyroid follicular carcinoma in nonirradiated rats ranged from 0 to 7%. Mean serum thyroid-stimulating hormone (TSH) values in irradiated animal groups were elevated significantly above those for age-matched nonirradiated animals. The degree of TSH elevation in irradiated animals was related directly to the testosterone-replacement level. All rat groups showed age-dependent decreases in serum T4 levels, and T4 levels were also lowered by replacement testosterone in nonirradiated castrated animals. In aging irradiated animals, serum T4 levels were similarly decreased by testosterone, despite elevated TSH levels in these groups. In this study, testosterone appeared to act indirectly to promote development of irradiation-induced thyroid tumors by early and prolonged elevation of TSH levels.

    A dog developed a cervical mass, and computed tomography verified a mass surrounding the trachea with some pulmonary masses. Histopathologically, the cervical mass was composed of malignant neoplastic cells showing follicular appearance which reacted positive for thyroglobulin on immunohistochemistry. A characteristic feature of the tumor was abundant and metaplastic stromal components. Anastomosed collagenous tissues connecting to capsule of the tumor were abundant in the stroma. In parts of the collagenous tissues, mature cartilages and bones were continuously formed. There was no cellular atypia or invasion in the components. We diagnosed this case as follicular thyroid carcinoma with metaplastic stroma. This is the first case report that characterizes stromal components with chondroid and osseous metaplasia in a canine thyroid carcinoma. PMID:24805905

    A role of environmental factors for the development of Medullary Carcinoma of the Thyroid (MTC) has been shown for animals, but has only been speculated for humans. In the present study we analyzed our registry of 58 sporadic MTCs for the place of origin and place of residence and compared these with 408 other thyroid carcinomas of different histology who are attending the same Endocrine Clinics in the Athens area. Clustering of sporadic MTCs was observed in the Ionian islands, where an increased incidence of familial cases has previously been observed. Patients with sporadic MTCs originated more frequently from rural areas (p = 0.0006), where the main occupation is agriculture. No important differences were observed concerning the place of residence. We speculate that exposure to sunshine, which is greater in rural areas, may be one factor which, through vitamin D, could be involved in the development of C-cell tumors in predisposed individuals.

In a diagnostic whole body 131I scan of a patient with follicular carcinoma, a posterior skull lesion was partially hidden by overlapping facial structures. On lateral head view, the abnormality was clearly evident. SPECT/CT and MRI showed the lesion originated in the occipital bone and had enlarged into the posterior fossa. The mass was surgically removed and the patient received 131I therapy for residual tissue. The study demonstrates a pitfall in the reading of two dimensional radioiodine images which can be overcome by SPECT or lateral imaging. PMID:23845451

    Three patients’ medical history, clinical manifestation, imaging characteristic, therapy and prognosis of calvaria metastasis from follicular thyroid carcinoma (FTC) in our hospital were retrospectively analyzed by reviewing medical literature. In case one, the tumor in frontal bone and fossa orbital was total resected, no further treatment was performed, the patient gave up on therapy and died of extensive metastasis at 22 months after the initial operation. In case two, the tumor in parietal and occipital bone was total resected, the subtotal resection of bilateral thyroid gland and isthmus was performed and combined with therapy of Levothyroxine and 131I radio-iodine therapy, no evidence of tumor recurrence at 30 months after the primary operation. In case three, the tumor in occipital bone was gross total resected, total resection of bilateral thyroid gland and clearance of lymph node was performed after two months, adjunctive therapy with Levothyroxine, 131I radio-iodine and skull radiotherapy, no evidence of tumor recurrence at 21 months after the primary operation. Correct diagnosis of calvaria metastasis from FTC preoperative is difficult because it’s rarity, patients can survive for years after synthetic therapy including total resection of metastatic tumor, radical operation of thyroid carcinoma, adjunctive therapy of Levothyroxine, 131I radio-iodine and skull radiotherapy.

    Carcinoma of the thyroid is usually delineated as a cold defect on images with radioiodine and Tc-99m pertechnetate. However, several cases that showed an accumulation of Tc-99m pertechnetate in thyroid carcinoma or in their metastases, but did not show any accumulation of radioiodine, have been reported. This paper presents a rare case of an advanced follicular adenocarcinoma of the thyroid that accumulated both Tc-99m pertechnetate and I-131. In this 41-year-old male patient, there were two primary foci in the thyroid; one occupied the whole left lobe with extension to the mediastinum and the other located in the lower part of the right lobe. In addition, there was a lymph node metastasis in the upper mediastinum adjacent to the left lobe. On images with both I-131 and Tc-99m pertechnetate, the tumor in the left lobe and the metastatic lymph node were delineated, but the tumor in the right lobe was not. Accumulation of Tc-99m pertechnetate in the lower part of the tumor of the left lobe was more distinct than that of I-131. Therefore, it is considered that despite similar histologic findings the trapping ability of the cancerous tissue differed from area to area.

    Thyroid cancer is a malignant neoplasm originated from thyroid cells. It can be classified into papillary carcinomas (PTCs) and anaplastic carcinomas (ATCs). Although ATCs are in an very aggressive status and cause more death than PTCs, their difference is poorly understood at molecular level. In this study, we focus on the transcriptome difference among PTCs, ATCs and normal tissue from a published dataset including 45 normal tissues, 49 PTCs and 11 ATCs, by applying a machine learning method, maximum relevance minimum redundancy, and identified 9 genes (BCL2, MRPS31, ID4, RASAL2, DLG2, MY01B, ZBTB5, PRKCQ and PPP6C) and 1 miscRNA (miscellaneous RNA, LOC646736) as important candidates involved in the progression of thyroid cancer. We further identified the protein-protein interaction (PPI) sub network from the shortest paths among the 9 genes in a PPI network constructed based on STRING database. Our results may provide insights to the molecular mechanism of the progression of thyroid cancer. PMID:24718460

However, no lesion was found in the thyroid gland; and the patient's thyroid function test results were normal. The tumor cells were immunoreactive for PAX2 and PAX8 but lacked reactivity for thyroglobulin and thyroid transcription factor-1.

    2015-01-01

    Background: Differentiated thyroid cancer (DTC) is among the most common malignancies in the adolescent and young adult (age 15–39 years) population, and its incidence is rising. Younger age (<45 years) is an important prognostic indicator and is incorporated into the TNM classification system. This study hypothesized that this would result in distinct treatment patterns for younger and older patients. Methods: Using the California Cancer Registry, 24,362 patients with DTC from 2004 to 2011 were identified, and they were divided into younger (<45 years) and older (≥45 years) cohorts. Demographic and clinical variables were tabulated and then compared using chi-square tests. Treatment variables included total or near total thyroidectomy, other types of thyroid surgery, and the administration of radioiodine as part of the initial treatment. Multivariable logistic regression was used to identify independent predictors of treatment administered. Results: Younger patients were more likely to be Hispanic (32.5% vs. 21.2%) and female (82.7% vs. 74.7%), and to have papillary carcinoma (92.9% vs. 90.9%) and lymph node involvement (32.8% vs. 19.7%; p<0.0001). On multivariable analysis, younger patients (OR 1.20 [CI 1.11–1.30]), higher T-stage tumors, higher socioeconomic status (SES), and papillary carcinoma were predictors of undergoing total thyroidectomy versus less than total thyroid surgery. After adjustment, predictors of radioiodine administration included younger age (OR 1.12 [CI 1.05–1.18]), higher SES, total thyroidectomy, higher T stage, and lymph node positivity. Conclusions: Younger patients with DTC in California are more likely to be female and Hispanic with papillary histology. After adjustment for disease and demographic characteristics, younger patients are more likely to undergo total thyroidectomy as their initial surgery and are more likely to receive radioiodine.

    Thyroid cancer is among the most common endocrine malignancies. Genetic and environmental factors play an important role in the pathogenesis of differentiated thyroid cancer. Both have good prognosis but with frequent recurrences. Cancer staging is an essential prognostic part of cancer management. There are multiple controversies in the management and followup of differentiated thyroid cancer. Debate still exists with regard to the optimal surgical approach but trends toward a more conservative approach, such as lobectomy, are being more favored, especially in papillary thyroid cancer, of tumor sizes less than 4 cm, in the absence of other high-risk suggestive features. Survival of patients with well-differentiated thyroid cancer was adversely affected by lymph node metastases. Prophylactic central LN dissection did improve accuracy in staging and decrease postop TG level, but it had no effect on small-sized tumors. Conservative approach was more applied with regard to the need and dose of radioiodine given postoperatively. There have been several advancements in the management of radioiodine resistant advanced differentiated thyroid cancers. Appropriate followup is required based on risk stratification of patients postoperatively. Many studies are still ongoing in order to reach the optimal management and followup of differentiated thyroid cancer. PMID:23326756

    The role of EGF and TGF-β1 in thyroid cancer is still not clearly defined. TGF-β1 inhibited the cellular growth and migration of follicular (FTC-133) and papillary (B-CPAP) thyroid carcinoma cell lines. Co-treatments of TGF-β1 and EGF inhibited proliferation in both cell lines, but displayed opposite effect on their migratory capability, leading to inhibition in B-CPAP and promotion in FTC-133 cells, by a MAPK-dependent mechanism. TGF-β1, TβRII and EGFR expressions were evaluated in benign and malignant thyroid tumors. Both positivity (51.7% and 60.0% and 80.0% in FA and PTC and FTC) and overexpression (60.0%, 77.7% and 75.0% in FA, PTC and FTC) of EGFR mRNA correlates with the aggressive tumor behavior. The moderate overexpression of TGF-β1 and TβRII mRNA in PTC tissues (61.5% and 62.5%, respectively), counteracted their high overexpression in FTC tissues (100% and 100%, respectively), while EGFR overexpression was similar in both carcinomas. Papillary carcinomas were positive to E-cadherin expression, while the follicular carcinomas lose E-cadherin staining. Our findings of TGF-β1/TβRII and EGFR overexpressions together with a loss of E-cadherin observed in human follicular thyroid carcinomas, and of increased migration ability MAPK-dependent after EGF/TGF-β1 treatments in the follicular thyroid carcinoma cell line, reinforced the hypothesis of a cross-talk between EGF and TGF-β1 systems in follicular thyroid carcinomas phenotype. - Highlights: • We reinforce the hypothesis of a cross talk between EGF and TGF-β1 in follicular thyroid carcinoma. • Increased migration MAPK-dependent is observed after EGF+TGF-β1 treatment in follicular thyroid carcinoma cells. • EGF and TGF-β1 caused opposite effect on the migratory ability in B-CPAP and in FTC-133 cells. • TGF-β1, TβRII and EGFR are overexpressed in follicular thyroid carcinoma.

    Molecular imaging based personalized therapy has been a fascinating concept for individualized therapeutic strategy, which is able to attain the highest efficacy and reduce adverse effects in certain patients. Theranostics, which integrates diagnostic testing to detect molecular targets for particular therapeutic modalities, is one of the key technologies that contribute to the success of personalized medicine. Although the term “theranostics” was used after the second millennium, its basic principle was applied more than 70 years ago in the field of thyroidology with radioiodine molecular imaging. Differentiated thyroid cancer, which arises from follicular cells in the thyroid, is the most common endocrine malignancy, and theranostic radioiodine has been successfully applied to diagnose and treat differentiated thyroid cancer, the applications of which were included in the guidelines published by various thyroid or nuclear medicine societies. Through better pathophysiologic understanding of thyroid cancer and advancements in nuclear technologies, theranostic radioiodine contributes more to modern tailored personalized management by providing high therapeutic effect and by avoiding significant adverse effects in differentiated thyroid cancer.

    The present study reports a rare case of a renal clear cell carcinoma with thyroid and parotid metastases. A 56-year-old female, with a painless, right preauricular mass present for 6 months was referred to Renji Hospital (Shanghai, China). Physical examination revealed a mass of 3×3 cm, which was smooth, firm, immobile and non-tender. There was no accompanying facial weakness. Parotid ultrasonography revealed a hypoechoic mass within the right parotid gland, which was potentially a parotid mixed tumor. In July 2011, the patient underwent a superficial parotidectomy with preservation of the facial nerve. Pathology confirmed as right parotid clear cell carcinoma (metastasis). The patient's relevant medical history included a right radical nephrectomy for renal clear cell carcinoma (clinical stage III) in 2004. Additionally, in 2009, the patient underwent a resection of thyroid metastatic renal cell carcinoma. To the best of our knowledge, no similar case has previously been reported in English-language literature. The present study discusses a case report, and investigates the clinical features and treatment strategy. PMID:26622899

    Papillary thyroid carcinoma (PTC) is the most common adult thyroid malignancy and often presents with multiple anatomically distinct foci within the thyroid, known as multifocal papillary thyroid carcinoma (MPTC). The widespread application of the next-generation sequencing technologies in cancer genomics research provides novel insights into determining the clonal relationship between multiple tumours within the same thyroid gland. For eight MPTC patients, we performed whole-exome sequencing and targeted region sequencing to identify the non-synonymous point mutations and gene rearrangements of distinct and spatially separated tumour foci. Among these eight MPTCs, completely discordant mutational spectra were observed in the distinct cancerous nodules of patients MPTC1 and 5, suggesting that these nodules originated from independent precursors. In another three cases (MPTC2, 6, and 8), the distinct MPTC foci of these patients had no other shared mutations except BRAF V600E, also indicating likely independent origins. Two patients (MPTC3 and 4) shared almost identical mutational spectra amongst their separate tumour nodules, suggesting a common clonal origin. MPTC patient 7 had seven cancer foci, of which two foci shared 66.7% of mutations, while the remaining cancer foci displayed no common non-synonymous mutations, indicating that MPTC7 has multiple independent origins accompanied by intraglandular disease dissemination. In this study, we found that 75% of MPTC cases arose as independent tumours, which supports the field cancerization hypothesis describing multiple malignant lesions. MPTC may also arise from intrathyroidal metastases from a single malignant clone, as well as multiple independent origins accompanied by intrathyroidal metastasis. PMID:27071483

    The present study aimed to discuss the advantage of the application of a cervical low incision for functional neck dissection in patients with thyroid papillary carcinoma. The study was a retrospective analysis of 87 thyroid papillary carcinoma patients; cervical low incision in the functional neck dissection was applied for 47 cases and the classic ‘L’ incision was applied for 40 cases. The different integrity, surgical time, blood loss and the aesthetic property of the incision were compared between the cervical low incision and the classic ‘L’ incision for lateral neck dissection of thyroid cancer. The postoperative pathological diagnosis was that the average total amount and the region II lymph nodes of the unilateral neck dissection were 33 and 10 for the cervical low incision group, and 32 and 11 for the classic ‘L’ incision group, respectively (P>0.05). The average unilateral neck dissection times were 87 and 58 min for the cervical low incision group and the classic ‘L’ incision group, respectively (P<0.05). The blood loss of the cervical low incision group was 67 ml, while the loss for the classic ‘L’ incision group was 61 ml (P>0.05). The postoperative incision of the cervical low incision group was smaller and more concealing. Additionally, the cosmetic deformities were milder for an inconspicuous cervical scar, and the sensation was improved for the patients in comparison with the classic ‘L’ incision group. These results suggest that the application of cervical low incision for functional neck dissection in thyroid papillary carcinoma patients aids in reducing postoperative complications, without increasing recurrence rates. Therefore, the classic ‘L’ incision can be replaced by the cervical low incision. PMID:27073645

    Differentiated thyroid carcinomas represent about 90% of all thyroid tumors and are divided in papillary and follicular carcinomas. Their prognosis is good, however, recurrences are not rare. Their ability to accumulate iodine is used for the radioactive iodine treatment. The aim of the postoperative radioactive iodine ablation therapy is the complete elimination of remnant thyroid cells and sensitive staging (Fig. 1). The recurrence rate decreases after a complete thyroid ablation. Furthermore, thyroglobulin can be used as a sensitive tumor marker. Radioactive iodine treatment by itself describes the therapy of metastases. An exception is the papillary microcarcinoma, which in general is treated by a lobectomy alone. PMID:26558927

  8. Treatment strategies for radioactive iodine-refractory differentiated thyroid cancer

    PubMed Central

    2014-01-01

    Until recently, no truly effective treatment options have existed for patients with radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC), a serious disease with poor prognosis. In November 2013, the targeted multikinase inhibitor, sorafenib, was approved for use in these patients based on substantially improved progression-free survival compared with placebo. A number of other targeted agents, including lenvatinib, are being investigated in phase II and phase III trials. With the advent of these new treatment options, practitioners are faced with making important decisions in determining which patients are candidates for systemic treatment and the optimal timing for treatment initiation. Since patients may remain asymptomatic for a protracted period of time, tumor size and growth rate are the primary considerations for making these choices. Proactive management of side effects is also critical in optimizing the effectiveness of treatment. Here we review targeted systemic agents that are either in use or are under investigation for RAI-refractory DTC and provide recommendations on the rationale for initiating systemic treatment and on managing adverse events. Four illustrative case studies are provided. PMID:25364392

    The concept of individualized therapy is rapidly gaining recognition in the management of patients with differentiated thyroid cancer (DTC). This Review provides an overview of the most important elements of this paradigm shift in DTC management and discusses the implications for clinical practice. In the majority of patients with DTC who have an inherently good prognosis, the extent of surgery, the dosage of (131)I therapy and the use of levothyroxine therapy are all aspects suitable for individualization, on the basis of both the stage of disease and the response to treatment. In individuals with advanced disease, newer imaging techniques, advances in (131)I therapy and the use of targeted molecular therapies (such as multitargeted kinase inhibitors) have provided new options for the personalized care of patients, for whom until recently no effective therapies were available. Individualized therapies could reduce adverse effects, including the sometimes debilitating hypothyroidism that used to be required before initiation of (131)I treatment, and major salivary gland damage, a common and unpleasant side effect of (131)I therapy. Highly individualized interdisciplinary treatment of patients with DTC might lead to improved outcomes with reduced severity and frequency of complications and adverse effects. However, in spite of ongoing research, personalized therapies remain in their infancy. PMID:24981455

    Patients with differentiated thyroid cancer (DTC) usually have an excellent prognosis. Following surgical and radioiodine treatment to remove the cancer cells and suppressive doses of levothyroxine, long-term follow-up, including measurement of serum thyroglobulin (Tg) using a sensitive assay is required to detect recurrence. To interpret Tg results clinicians need to know the corresponding serum TSH concentration, have an appreciation of the clearance of Tg from patient serum following various interventions and the limitations of its measurement. The limitations of Tg immunoassay are well described and include potential interference from TgAb. For the majority of patients with DTC who are TgAb-negative, Tg measurement remains the most useful method of follow-up. For the TgAb-positive minority, interference and the possibility of producing erroneous results is a concern. Some assays are less badly affected than others and laboratories are advised to choose their assays carefully. Laboratories have sought to identify interferences using measurement of TgAb, lack of concordance between RIAs and immunometric assays and recovery of added Tg. More recently LC-MSMS assays to quantify Tg have been developed. They are not currently as sensitive as Tg immunoassays and it is likely these assays will, like immunoassays, be limited by Tg heterogeneity and standardization issues, although initial evaluations indicate that they may have value in the clinical setting as a second line test in antibody-positive DTC patients in whom Tg is unmeasurable by immunoassay.

    Telomerase activation through induction of its catalytic component telomerase reverse transcriptase (TERT) expression is essential for malignant transformation. TERT promoter mutations namely C228T and C250T that stimulate TERT transcription and telomerase activation have recently been identified in many human malignancies. We thus determined these mutations and their biological and clinical implications in thyroid carcinomas in the present study. The TERT promoter was sequenced in 10 thyroid cancer cell lines and 144 tumors from 20 patients with anaplastic thyroid carcinoma (ATC), 51 with papillary thyroid carcinoma (PTC), 36 with follicular thyroid carcinoma (FTC), and 37 with medullary thyroid carcinoma (MTC). We identified C228T or C250T mutation in 6/8 of ATC cell lines, as well as in tumor tissue from 10/20, 13/51, 8/36 and 0/37 patients with ATC, PTC, FTC and MTC, respectively. In PTC patients, these mutations were exclusively present in the group with age >45 years (P<0.0001), and highly correlated shorter telomeres (P<0.0001) and distant metastasis (P=0.028). The previous radioactivity exposure did not induce the mutation. The presence of C228T or C250T was an independent predictor associated with shorter disease-related survival (DRS) in the entire cohort (P<0.0001), as well as among patients >45 years (P=0.021). ATC patients carrying the mutation survived shorter than those without mutations, although not statistically significant (P=0.129). The TERT promoter mutation was associated with overall survival (P=0.038) and DRS (P=0.058) of FTC patients. Taken together, age- and shorter telomere-dependent TERT promoter mutations occur frequently in follicular cell-derived thyroid carcinoma (ATC, PTC and FTC) but not in parafollicular cell-originated MTC, and may serve as a marker for aggressive disease and poor outcome.

    A chromosomal translocation results in production of an oncogenic PAX8-PPARG fusion protein (PPFP) in thyroid carcinomas. PAX8 is a thyroid transcription factor, and PPARG is a transcription factor that plays important roles in adipocytes and macrophages. PPFP retains the DNA binding domains of both proteins; however, the genomic binding sites of PPFP have not been identified, and only limited data exist to characterize gene expression in PPFP thyroid carcinomas. Therefore, the oncogenic function of PPFP is poorly understood. We expressed PPFP in PCCL3 rat thyroid cells and used ChIP-seq to identify PPFP genomic binding sites (PPFP peaks) and RNA-seq to characterize PPFP-dependent gene expression. PPFP peaks (~20,000) include known PAX8 and PPARG binding sites and are enriched with both motifs, indicating that both DNA binding domains are functional. PPFP binds to and regulates many genes involved in cancer-related processes. In PCCL3 thyroid cells, PPFP binds to adipocyte PPARG target genes in preference to macrophage PPARG target genes, consistent with the pro-adipogenic nature of PPFP and its ligand pioglitazone in thyroid cells. PPFP induces oxidative stress in thyroid cells, and pioglitazone increases susceptibility to further oxidative stress. Our data highlight the complexity of PPFP as a transcription factor and the numerous ways that it regulates thyroid oncogenesis. PMID:26595524

  14. Molecular genetics of childhood papillary thyroid carcinomas after irradiation: high prevalence of RET rearrangement.

    Epidemiological studies have revealed a connection between thyroid carcinogenesis and a history of radiation. The molecular mechanisms involved are not well understood. It has been claimed that RAS, p53 or GSP mutations and RET or TRK rearrangements might play a role in adult thyroid tumors. In childhood, the thyroid gland is particularly sensitive to ionizing radiation. The reactor accident in Chernobyl provided a unique chance to study molecular genetic aberrations in a cohort of children who developed papillary thyroid carcinomas after a short latency time after exposure to high doses of radioactive iodine isotopes. According to the concepts of molecular genetic epidemiology, exposure to a specific type of irradiation might result in a typical molecular lesion. Childhood papillary thyroid tumors after Chernobyl exhibit a high prevalence of RET rearrangement as almost the only molecular alteration. The majority showed RET/PTC3 (i.e., ELE/RET rearrangements), including several subtypes. Less frequently, RET/PTC1 (i.e., H4/RET rearrangements), and a novel type (RET/PTC5, i.e., RFG5/RET) were observed. Proof of reciprocal transcripts suggests that a balanced intrachromosomal inversion leads to this rearrangement. Breakpoint analyses revealed short homologous nucleotide stretches at the fusion points. In all types of rearrangement, the RET tyrosine kinase domain becomes controlled by 5' fused regulatory sequences of ubiquitously expressed genes that display coiled-coil regions with dimerization potential. Oncogenic activation of RET is apparently due to ligand-independent constitutive ectopic RET tyrosine kinase activity. The analysis of this cohort of children with radiation-induced thyroid tumors after Chernobyl provides insights into typical molecular aberrations in relation to a specific mode of environmental exposure and may serve as a paradigm for molecular genetic epidemiology.

    This study evaluates breast milk secretion of {sup 131}I following therapeutic adminstration of 4000 MBq of {sup 131}I-iodide during lactation. Breast milk {sup 131}I activity concentration was measured over a 32-day period. Dosimetry calculations were undertaken to estimate the period for discontinuation of breast feeding and the equivalent dose to the breasts. To achieve an infant effective dose <1 mSv and an infant thyroid dose <10 mSv, breast feeding would need to be discontinued for at least 52 days. The estimated equivalent dose to the breasts was 1.6 Gy. It is suggested that {sup 131}I-iodide adminstration is not undertaken during lactation and that breast feeding is discontinued several days prior to administration. 26 refs., 2 figs., 2 tabs.

    Background Thyroid cancer is a very common endocrine malignancy, with a rate of total thyroidectomy reported to be up to 27.8%. However, studies analyzing the risk factors that contribute to recurrence of papillary thyroid carcinoma (PTC) after total thyroidectomy in China are still scarce. Material/Methods A total of 536 patients with PTC who underwent total thyroidectomy were retrospectively analyzed. Patients were divided into 2 groups: patients with no recurrent tumor were included in group 1 and patients with tumor recurrence were included in group 2. Results Of 536 patients, 65 patients (12.1%) developed a recurrence of PTC, and 471 patients (87.9%) did not have a recurrence. Univariate analysis indicated that male sex, age ≥50 years, tumor ≥1 cm, poor differentiation, lymph node metastasis, bilaterality, and multifocality may be related to PTC recurrence. Additionally, the results of the logistic regression analysis indicated that male sex, age ≥50 years, primary tumor ≥1 cm, poor dedifferentiation of the tumor, lymph node metastasis, and multifocality may be independent factors contributing to PTC recurrence. Conclusions Male sex, age more than 50 years, primary tumor larger than 1 cm, poor dedifferentiation of the primary tumor, lymph node metastasis, and multifocality were found to increase the risk of PTC recurrence in patients who underwent total thyroidectomy. Additionally, it is necessary to use strictly aggressive and extensive surgery, as well as close monitoring, after the operation. PMID:27084873

    Advanced thyroid cancer is not amenable to therapy with conventional cytotoxic chemotherapy. However, newer advances in the understanding of the molecular pathogenesis of different subtypes of thyroid cancer have provided new opportunities for the evaluation of molecularly targeted therapies. This has led to multiple clinical trials using various multi-kinase inhibitors and the subsequent US FDA approval of sorafenib for differentiated thyroid cancer and vandetanib and cabozantinib for medullary thyroid carcinoma. This review provides a summary of the current literature for the treatment of advanced thyroid carcinoma and future directions in this disease. PMID:26335853

    Introduction. Recombinant human thyroid stimulating hormone (rhTSH) is approved for preparation of thyroid remnant ablation with radioactive iodine (RAI) in low risk patients with well differentiated thyroid cancer (DTC). We studied the safety and efficacy of rhTSH preparation for RAI treatment of thyroid cancer patients with nodal metastatic disease. Methods. A retrospective analysis was performed on 108 patients with histopathologically confirmed nodal metastatic DTC, treated with initial RAI between January 1, 2000, and December 31, 2007. Within this selected group, 31 and 42 patients were prepared for initial and all subsequent RAI treatments by either thyroid hormone withdrawal (THW) or rhTSH protocols and were followed up for at least 3 years. Results. The response to initial treatment, classified as excellent, acceptable, or incomplete, was not different between the rhTSH group (57%, 21%, and 21%, resp.) and the THW group (39%, 13%, and 48%, resp.; P = 0.052). There was no significant difference in the final clinical outcome between the groups. The rhTSH group received significantly fewer additional doses of RAI than the THW group (P = 0.03). Conclusion. In patients with nodal-positive DTC, preparation for RAI with rhTSH is a safe and efficacious alternative to THW protocol. PMID:26977148

    This study delineates tumor characteristics which predispose serum thyroglobulin (TG) to be undetectable in patients in spite of persistent or recurrent differentiated thyroid cancer. Three hundred seventy four thyroid carcinoma patients with completed thyroid ablation were investigated by means of conventional diagnostic procedures (iodine-131 total-body scan, x-ray, TG determination) and, in addition, with high-resolution sonographic study of the neck. Sensitivity of TG for the detection of metastases amounted to 83% under TSH stimulation and 50% under thyroxine (T4) treatment. Specificity proved to be 95% under TSH stimulation and 99% under T4 treatment. Common features of the tumors associated with false-negative TG determinations (n = 16) were papillary histologic characteristics, manifestation in lymph nodes of the neck or mediastinum, and small size. It is therefore necessary for the early detection of persistent or recurrent papillary cancer metastases to perform in addition to iodine-131 scans high-resolution sonography of the neck in combination with the determination of TG serum concentrations under endogenous TSH stimulation.

    Summary Type II deiodinase (D2) plays a critical role in controlling intracellular T3 concentration and early studies indicated a follicular but not a parafollicular C-cell origin of D2 activity in the thyroid gland. Here, we show that D2 is highly expressed in human medullary thyroid carcinoma (MTC), a tumour that arises from the C-cells. D2 transcripts were detected in all MTC samples obtained from 12 unselected MTC patients and the levels of D2 activity were comparable to those found in surrounding normal follicular tissue (0.41±0.10 vs 0.43±0.41 fmol.min.mg.protein, P=0.91). Additional analysis in the TT cells, a human MTC cell line, demonstrated that the D2 expression is down regulated by thyroid hormones and enhanced by cAMP analogs and dexamethasone. The thyroid hormone receptor α1 and β isoforms were also detected in all MTC samples and in TT cells, thus suggesting a potential role of T3 locally produced by D2 in this neoplastic tissue.

    Differentiation between complicated cholecystitis and advanced gallbladder carcinoma can be difficult when clinical findings are confusing. Computed tomographic (CT) scans were reviewed from 22 patients with a surgical diagnosis of complicated cholecystitis (11 cases) or advanced gallbladder carcinoma (11 cases). The presence of a curvilinear low-attenuation halo around the gallbladder wall was specific for complicated cholecystitis. Findings indicative of gallbladder carcinoma included a focal soft-invasion or metastases. Knowledge of these differential CT findings may result in a more accurate preoperative diagnosis.

    The aim of this study was to evaluate the potential of applying silver nano-particle based surface-enhanced Raman scattering (SERS) to discriminate different types of human thyroid tissues. SERS measurements were performed on three groups of tissue samples including thyroid cancers (n = 32), nodular goiters (n = 20) and normal thyroid tissues (n = 25). Tentative assignments of the measured tissue SERS spectra suggest interesting cancer specific biomolecular differences. The principal component analysis (PCA) and linear discriminate analysis (LDA) together with the leave-one-out, cross-validated technique yielded diagnostic sensitivities of 92%, 75% and 87.5%; and specificities of 82.6%, 89.4% and 84.4%, respectively, for differentiation among normal, nodular and malignant thyroid tissue samples. This work demonstrates that tissue SERS spectroscopy associated with multivariate analysis diagnostic algorithms has great potential for detection of thyroid cancer at the molecular level.

    Papillary Thyroid Carcinoma (PTC) is the most frequent thyroid cancer. Although several PTC-specific miRNA profiles have been reported, only few upregulated miRNAs are broadly recognized, while less consistent data are available about downregulated miRNAs. In this study we investigated miRNA deregulation in PTC by miRNA microarray, analysis of a public dataset from The Cancer Genome Atlas (TCGA), literature review and meta-analysis based on a univocal miRNA identifier derived from miRBase v21. A list of 18 miRNAs differentially expressed between PTC and normal thyroid was identified and validated in the TCGA dataset. Furthermore, we compared our signature with miRNA profiles derived from 15 studies selected from literature. Then, to select possibly functionally relevant miRNA, we integrated our miRNA signature with those from two in vitro cell models based on the PTC-driving oncogene RET/PTC1. Through this strategy, we identified commonly deregulated miRNAs, including miR-451a, which emerged also by our meta-analysis as the most frequently reported downregulated miRNA. We showed that lower expression of miR-451a correlates with aggressive clinical-pathological features of PTC as tall cell variant, advanced stage and extrathyroid extension. In addition, we demonstrated that ectopic expression of miR-451a impairs proliferation and migration of two PTC-derived cell lines, reduces the protein levels of its recognized targets MIF, c-MYC and AKT1 and attenuates AKT/mTOR pathway activation. Overall, our study provide both an updated overview of miRNA deregulation in PTC and the first functional evidence that miR-451a exerts tumor suppressor functions in this neoplasia. PMID:26871295

    A prospective study and follow-up program of 2,118 patients with prior low-dose head and neck irradiation, entered into a thyroid screening project, allowed us to examine how the extent of operation and pathology technique influenced the incidence of thyroid carcinoma. Patients with palpable nodular thyroid disease were referred to their physicians with a recommendation for surgery: 107 patients had thyroid surgery in community hospitals (CHs) where enucleation of the nodule or lobectomy was the usual operation, and 29 patients had surgery at Milwaukee County Medical Complex (MCMC) where near-total thyroidectomy was routine. Lymph nodes were sampled in 69% of MCMC operations but in only 16% of CH operations. The pathologist's usual method at MCMC was to submit the total surgical specimen and to do serial sections. Less than total specimen examination and random sections typically were done in community hospitals. The mean age and sex ratio of the patients and size of thyroid lesions in the two groups were not different. Cancer was found in 59% (17/29) of patients who underwent operation at MCMC, while only 21% (22/107) of patients who underwent operation in CHs were found to have carcinoma (P less than 0.001). Surprisingly, there was nearly uniform agreement (99%) in the diagnoses made by MCMC and CH pathologists, and the incidence of microscopic foci of carcinoma was similar in both groups. We conclude that the incidence of thyroid carcinoma found in patients with prior head and neck irradiation who have had operation for thyroid nodules is related to the extent of thyroidectomy, routine lymph node sampling, the amount of resected thyroid tissue processed for histologic examination, and the absolute number of sections examined by the pathologist.

    A seven-year-old entire male Irish setter was presented because of a neck mass, prolapse of the third eyelid and apparent drooping of the upper eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable findings on physical examination were right-sided Horner's syndrome, pre-scapular lymphadenopathy and a large, ventral cervical mass. Lateral cervical radiographs showed a large, soft tissue opacity surrounding the trachea and retropharyngeal area which was causing displacement and narrowing of the cervical trachea and oesophagus. Results of thyroid testing suggested hyperthyroidism. At necropsy, a large, invasive tumour was identified in the ventral cervical region and multiple metastases of various sizes were detected in the lungs. Histopathological examination of the tumour revealed follicular thyroid carcinoma and confirmed widespread pulmonary metastasis. PMID:8981280

    2014-01-01

    Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical resection was performed because the ultrasonogram showed diffuse microcalcifications, which suggested malignancy, and clinically, the mass grew rapidly to compress the trachea. Local tumor recurrence was noted at 3 months after surgery. Surgical resection or repeat biopsy should be considered if a cytologically benign thyroid mass shows imaging or clinical features of malignancy. PMID:24936508

    2016-02-01

    Medullary thyroid carcinoma (MTC) is a neuroendocrine malignancy of the thyroid C cells that occurs in hereditary and sporadic clinical settings. Metastatic spread commonly occurs to cervical and mediastinal lymph nodes. MTC cells do not concentrate radioactive iodine and are not sensitive to hormonal manipulation, and therefore surgery is the most effective option for curative therapy, reduction in tumor burden, or effective palliation. In patients undergoing preventative surgery for hereditary MTC, central lymph node dissection should be considered if the calcitonin level is elevated. Preservation of parathyroid function in these young patients is of paramount importance. In patients with established primary tumors, systematic surgical removal of lymph node basins (compartmental dissection) should be guided by ultrasound mapping of lymph node metastases and level of serum calcitonin. A "berry-picking" approach is discouraged. Newly approved targeted molecular therapies offer wider treatment options for patients with progressive or metastatic disease. PMID:26539937

    We report a case of medullary thyroid carcinoma with a paraganglioma-like pattern and melanin production. Macroscopically, a rectangular black area within a gray-white background was seen on the cut surface of the tumor. Histologically, the tumor was found to have a trabecular or nestlike architecture with many pigmented dendritic cells, resembling the "sustentacular cells" of paraganglioma, scattered among nonpigmented polygonal tumor cells. Fontana-Masson staining and bleaching with potassium permanganate and oxalic acid revealed that this pigment was melanin, which was also confirmed by electron microscopy. Immunohistochemically, pigmented dendritic cells were positive for calcitonin, as were the surrounding typical medullary thyroid carcinoma cells. These cells were also positive for S100 protein but not for HMB-45, compatible with sustentacular cells. These findings suggest that this tumor could be considered to bridge the gap between two variants of medullary thyroid carcinoma, the melanin-producing (pigmented) type and the paraganglioma-like type.

    Thyroid cancer is one of the most rapidly increasing malignancies. The reasons for this increase is not completely known, but increases in the diagnosis of papillary thyroid microcarcinomas and follicular variant of papillary thyroid carcinomas along with the enhanced detection of well-differentiated thyroid carcinomas are probably all contributing factors. Although most cases of well-differentiated thyroid carcinomas are associated with an excellent prognosis, a small percentage of patients with well-differentiated thyroid carcinomas as well as most patients with poorly differentiated and anaplastic thyroid carcinomas have recurrent and/or metastatic disease that is often fatal. The cancer stem-like cell (CSC) model suggests that a small number of cells within a cancer, known as CSCs, are responsible for resistance to chemotherapy and radiation therapy, as well as for recurrent and metastatic disease. This review discusses current studies about thyroid CSCs, the processes of epithelial-to-mesenchymal transition (EMT), and mesenchymal-to-epithelial transition that provide plasticity to CSC growth, in addition to the role of microRNAs in CSC development and regulation. Understanding the biology of CSCs, EMT and the metastatic cascade should lead to the design of more rational targeted therapies for highly aggressive and fatal thyroid cancers. PMID:24788702

    Clear cell follicular carcinoma is a rare type of thyroid cancer and some with aggressive biological behavior. The cytoplasmic clearing of the neoplastic cells has been attributed to the accumulation of various substances, such as glycogen, lipid, mucin, and thyroglobulin, or distension of mitochondria or endoplasmic reticulum. However, the molecular mechanisms responsible for the characteristic appearance of the cell cytoplasm and the biological behavior remain unknown. We report here a case of aggressive clear cell follicular carcinoma of the thyroid with molecular profile using targeted next generation sequencing (NGS) that presented as a metastatic tumor in a woman with a history of breast carcinoma. The NGS data revealed the coexisting of a well-characterized loss-of-function TP53 R248Q mutation and a putative gain-of-function mutation of TSHR L272V, which was suggested by the overexpression of thyroglobulin and SLC5A5 (NIS) genes in this tumor. TP53 mutations are usually related with dedifferentiation, progression, and metastasis of thyroid carcinomas. Identification of TP53 R248Q in this tumor correlated with its aggressive clinical behavior. Gain-of-function mutation of TSHR can overstimulate the thyroid follicular cells as the elevated level of TSH does and might have contributed to the development of clear cell morphology in this tumor. This report represents the first case of clear cell follicular carcinoma of the thyroid with NGS analysis and more molecular characterization is needed to elucidate the pathogenesis and provide more prognosis-relevant information for this uncommon variant of thyroid carcinomas.

    Objectives. To compare the frequency of another primary malignancy in patients with differentiated thyroid carcinoma (DTC) who received radioiodine therapy or not (131I). Material and Methods. 168 cases of DTC patients were retrospectively evaluated as to the frequency of another neoplasia by comparing patients with and without it, taking into account clinical, laboratory, and therapeutic parameters. Results. Another primary malignancy occurred in 8.9% of patients. Of these, 53.3% showed the malignancy before 131I and 46.7% after it. By comparing both groups, the age at the moment of diagnosis of another neoplasia was 46.1 ± 20.2 years for the group before 131I therapy and of 69.4 ± 11.4 years for the group after it (P = 0.02). Of the 148 patients treated with 131I, 4.7% developed another malignancy. The latter were older (61 ± 17 years) than those who did not show another cancer type (44.1 ± 14.2 years) (P < 0.05). Conclusion. The frequency of another neoplasia found after 131I was similar to that found before 131I. PMID:22084737

    Cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is a rare tumor, which exceptionally occurs at pediatric age. CMV-PTC may develop in patients with familial adenomatous polyposis (FAP) or may be a sporadic tumor. The authors present a case of CMV-PTC in a 10-year-old girl patient without FAP history, who presented with a left neck mass. The patient underwent total thyroidectomy with central compartment neck dissection. Histopathological diagnosis was compatible with cribriform-morular variant of papillary thyroid carcinoma and Hashimoto's thyroiditis. Immunostaining was positive for thyroglobulin, β-catenin, CD10 and p53. Molecular test showed the absence of BRAF, K-RAS mutations, deletions or duplications of APC (adenomatosis polyposis coli) gene and showed the presence of RET÷PTC (rearranged during transfection÷papillary thyroid carcinoma) rearrangements. At 32 months follow-up, the patient was without signs of recurrence. This particular form of thyroid carcinoma should raise suspicion of a possible familial cancer syndrome, therefore early diagnosis and thoroughly evaluation, which includes colonoscopy and genetic screening are mandatory.

    Papillary thyroid carcinoma (PTC) composed by predominant solid areas is diagnosed as a distinct variant on histological samples. Here we present a case of PTC recognized preoperatively by fine needle cytology as a solid variant. This diagnosis was made by combining cytology with the detection of the BRAFVK600-1E mutation, the molecular hallmark of the solid variant of PTC. Histological and molecular evaluation of the surgical specimen confirmed this pre-operative diagnosis. Thus combining cytology to BRAF molecular analysis is useful to refine the cytological diagnosis of this variant also on FNC specimens. PMID:18353179

    Retinoic acid is a promising tool in adjuvant cancer therapies, including refractory thyroid cancer, and its biological role is mediated by the retinoic acid receptor beta (RARβ). However, expression of RARβ is lowered in papillary thyroid carcinoma (PTC), contributing to promotion of tumor growth and inefficiency of retinoic acid and radioactive iodine treatment. The causes of aberrant RARB expression are largely unknown. We hypothesized that the culpable mechanisms include the action of microRNAs from the miR-146 family, previously identified as significantly upregulated in PTC tumors. To test this hypothesis, we assessed the expression of RARB as well as miR-146a-5p and miR-146b-5p in 48 PTC tumor/normal tissue pairs by Taqman assay to reveal that the expression of RARB was 3.28-fold decreased, and miR-146b-5p was 28.9-fold increased in PTC tumors. Direct interaction between miRs and RARB was determined in the luciferase assay and further confirmed in cell lines, where overexpression of miR-146a-5p and miR-146b-5p caused a 31% and 33% decrease in endogenous RARB mRNA levels. Inhibition of miR-146a and miR-146b resulted in 62.5% and 45.4% increase of RARB, respectively, and a concomitant decrease in proliferation rates of thyroid cancer cell lines, analyzed in xCELLigence system.We showed that two microRNAs of the miR-146 family directly regulate RARB. Inhibition of miRs resulted in restoration of RARB expression and decreased rates of proliferation of thyroid cancer cells. By restoring RARB levels, microRNA inhibitors may become part of an adjuvant therapy in thyroid cancer patients. PMID:27011326

    Context: Cell lines are a widely used tool in cancer research. However, despite the relatively high incidence of papillary thyroid carcinoma (PTC), there are only four PTC cell lines available for international research audience. Objective: The objective of this study was to establish and characterize new PTC cell lines that represent primary tumor biology. Surgical specimens were obtained to generate PTC cell lines. Short tandem repeat profiling was used to confirm the uniqueness of the cell lines against databases of known cell lines and mutations were assessed using Sequenom. The expression of thyroid-specific genes was examined using real-time PCR. Tumorigenicity was determined using an orthotopic thyroid xenograft tumor mouse model. Results: Six PTC cell lines (five conventional PTCs and one follicular variant of PTC) were generated and found to be unique when compared by short tandem repeat profiling against databases of all existing cell lines. The five conventional PTC cell lines carry the BRAF V600E mutation and the follicular variant of PTC cell line had an NRAS mutation. Five of the six cell lines had a mutation in the promoter of the human telomerase reverse transcriptase gene. None of the cell lines have RET/PTC rearrangements. Three cell lines were tumorigenic in the orthotopic thyroid xenograft tumor mouse model. Conclusions: These five characterized conventional PTC cell lines and the unique follicular variant of PTC cell line should be valuable reagents for thyroid cancer research. The three tumorigenic cell lines can be used for in vivo testing of targeted therapeutic and novel agents. PMID:25427145

    Warthin-like variant of papillary thyroid carcinoma (WVPTC) is a rare entity recently characterized. We evaluated ultrasonographic (US) features and clinical characteristics of WVPTC. Nine patients were diagnosed with WVPTC through surgery in our institution from May 2005 to January 2015. Eight of nine patients had available preoperative US images. A retrospective review of the US and clinical characteristics was performed. WVPTC compromised of 0.06% of 14,071 PTCs surgically confirmed. A mean age of nine patients was 53.2 years (range, 32-75 years). The mean nodule size of nine WVPTCs was 0.9 cm (range, 0.5-1.5 cm). Two patients showed central nodal metastasis and one patient with conventional PTC as an index tumor underwent central and lateral neck dissection. No one showed recurrence or distant metastasis during the follow-up period (mean, 4.6 years; range, 0.6-10 years). The most common US features of WVPTCs were solid composition (62.5%), hypoechogenicity (75%), and wider-than-tall shape (100%), respectively. Four (50%) of eight nodules showed well-defined margin and three (37.5%) of them had cystic component. One of eight resembled focal thyroiditis. Three nodules were considered as probably benign with US. All nine cases demonstrated underlying heterogeneous parenchymal echogenicity and accompanied chronic lymphocytic thyroiditis in permanent sections. Thyroid function tests in all patients were normal except for one with subclinical hypothyroidism. WVPTC is an uncommon subtype of PTC and has favorable prognosis, which can be misdiagnosed as a probably benign nodule or focal thyroiditis with US. All cases are associated with heterogeneous parenchyma in the background. PMID:26806192

    INTRODUCTION Papillary thyroid cancer (PTC) is the most common thyroid malignancy and usually spreads via lymphatic system. PTC can sometimes show microscopic vascular invasion, but rarely causes tumour thrombus in the internal jugular vein (IJV) or other great veins of the neck. PRESENTATION OF CASE We report a case of a 62-year-old female presented with symptomatic central neck mass. Clinical examination revealed a hard solitary right-sided thyroid nodule with ipsilateral cervical lymphadenopathy. Ultrasonography (US) confirmed the clinical diagnosis and visualised a dilated ipsilateral IJV. Fine-needle aspiration cytology revealed PTC cells so total thyroidectomy with right neck dissection was done. A tumour thrombus was discovered in the distended right IJV and was cleared successfully. The patient recovered well after the operation with no local or distant metastasis detected. DISCUSSION Tumour vascular spread is observed in tumours with angio-invasive features including follicular carcinoma of the thyroid gland where great cervical veins can be affected. PTC commonly spreads to the lymph nodes and vascular spread via direct intravascular extension is extremely rare. Neck US has an important role in the diagnosis, and operators should attempt to detect signs of tumour thrombi in all patients with thyroid masses. Aggressive surgical treatment with vascular repair is recommended whenever possible to minimise the risk of potentially fatal complications of the intraluminal masses. CONCLUSION Intravascular tumour extension of PTC is rare but with serious consequences. Diagnosis with neck US is possible but some cases are only discovered intraoperatively. Thrombectomy with vascular repair or reconstruction is usually possible. PMID:25044067

To test this hypothesis, we assessed the expression of RARB as well as miR-146a-5p and miR-146b-5p in 48 PTC tumor/normal tissue pairs by Taqman assay to reveal that the expression of RARB was 3.28-fold decreased, and miR-146b-5p was 28.9-fold increased in PTC tumors. Direct interaction between miRs and RARB was determined in the luciferase assay and further confirmed in cell lines, where overexpression of miR-146a-5p and miR-146b-5p caused a 31% and 33% decrease in endogenous RARB mRNA levels. Inhibition of miR-146a and miR-146b resulted in 62.5% and 45.4% increase of RARB, respectively, and a concomitant decrease in proliferation rates of thyroid cancer cell lines, analyzed in xCELLigence system.We showed that two microRNAs of the miR-146 family directly regulate RARB. Inhibition of miRs resulted in restoration of RARB expression and decreased rates of proliferation of thyroid cancer cells. By restoring RARB levels, microRNA inhibitors may become part of an adjuvant therapy in thyroid cancer patients. PMID:27011326

    Advanced medullary thyroid cancers (MTCs) are now being treated with drugs that inhibit receptor tyrosine kinases, many of which involved in angiogenesis. Response rates vary widely, and toxic effects are common, so treatment should be reserved for MTCs likely to be responsive to these drugs. RET mutations are common in MTCs, but it is unclear how they influence the microvascularization of these tumors. We examined 45 MTCs with germ-line or somatic RET mutations (RETmut group) and 34 with wild-type RET (RETwt). Taqman Low-Density Arrays were used to assess proangiogenic gene expression. Immunohistochemistry was used to assess intratumoral, peritumoral and nontumoral expression levels of VEGFR1, R2, R3, PDGFRa, PDGFB and NOTCH3. We also assessed microvessel density (MVD) and lymphatic vessel density (LVD) based on CD31-positive and podoplanin-positive vessel counts, respectively, and vascular pericyte density based on staining for a-smooth muscle actin (a-SMA), a pericyte marker. Compared with RETwt tumors, RETmut tumors exhibited upregulated expression of proangiogenic genes (mRNA and protein), especially VEGFR1, PDGFB and NOTCH3. MVDs and LVDs were similar in the two groups. However, microvessels in RETmut tumors were more likely to be a-SMA positive, indicating enhanced coverage by pericytes, which play key roles in vessel sprouting, maturation and stabilization. These data suggest that angiogenesis in RETmut MTCs may be more intense and complete than that found in RETwt tumors, a feature that might increase their susceptibility to antiangiogenic therapy. Given their increased vascular pericyte density, RETmut MTCs might also benefit from combined or preliminary treatment with PDGF inhibitors. PMID:27402614

    Thyroglobulin (Tg) is a high molecular weight glycoprotein located mainly in thyroid follicles, where thyroid hormones are synthesized and stored. In patients with differentiated thyroid cancer of follicular origin, serum Tg levels become undetectable following total thyroidectomy and iodine-131 remnant ablation. It is a key biomarker to follow-up patients with differentiated thyroid cancer, in combination with neck ultrasound monitoring. The measurement of Tg in the wash-out of the needle used for fine needle aspiration biopsy is a valuable aid to the diagnosis of lymph node metastasis. The presence of anti-thyroglobulin antibodies affects reliability of Tg results measured in serum or plasma. Systematic investigation of such antibodies is required to validate any Tg assay. Elevated or rising levels of anti-thyroglobulin antibodies can in turn be used as a surrogate tumor marker of thyroid cancer. The development of second-generation Tg assay (automated, highly sensitive) has enabled significant advances in the management of differentiated thyroid cancer: early detection of persistent or recurrent disease and follow-up care simplified in low-risk patients. Testing of serum Tg can also be useful in evaluating other clinical situations such as congenital hypothyroidism, endemic goiter and thyrotoxicosis factitia. PMID:26711165

    Objective We sought to evaluate and compare the outcomes of different surgical protocols for papillary thyroid cancer (PTC) located in the isthmus in a retrospective intention-to-treat analysis. Patients and methods The data of 3,068 patients who received thyroidectomy due to thyroid cancer in our center were reviewed. Of these, 103 patients had a dominant carcinoma located in the isthmus. Various baseline and tumor characteristics and surgical outcomes were evaluated and compared with respect to the different surgical protocols (85 cases with total thyroidectomy and 18 cases with less-than-total thyroidectomy). Univariate and multivariate analyses were performed to identify resected patients who developed recurrence with isthmic PTC. Results The postoperative complication rates were comparable between the two groups (17.6% versus 11.1%, P=0.500). Although the total thyroidectomy group showed a much higher rate (P=0.004) and number (P<0.001) of parathyroidectomies, long-term follow-up indicated that parathyroid autotransplantation did not significantly damage the function of the parathyroid (P>0.05). Tumor recurrence was observed in five patients, including two patients in the total thyroidectomy group and three patients in the less-than-total thyroidectomy group; the tumor recurrence rate in the total thyroidectomy group was significantly lower than that in the less-than-total thyroidectomy group (P=0.040). Univariate and multivariate analyses indicated less-than-total thyroidectomy as a risk factor for tumor recurrence in PTC cases with tumors located at the isthmus (hazard ratio: 1.870, 95% confidence interval: 1.320–2.218, P<0.001). Conclusion Our findings indicate that total thyroidectomy is an appropriate initial surgical protocol for isthmic PTC due to the lower recurrence rate, comparable postoperative complication rate, and parathyroid function recovery.

    A cell line designated HOTHC was established from an anaplastic carcinoma (giant cell type) of the thyroid gland of 80-year-old woman. The HOTHC line grew rapidly in multilayer without contact inhibition, and more than 120 serial passages were made within 27 months. The cells were spindle or polygonal in shape and revealed neoplastic and pleomorphic features. These cells were characterized as containing coloid droplets and poorly developed rough-endoplasmic reticulum in the cytoplasm. Doubling time was about 24 hours and plating efficiency was about 70%. The karyotype exhibits hyperploidy and marker chromosomes, and the modal chromosome number ranged between 77-90. The HOTHC cells were transplanted into the subcutis of BALB/c nude mice and produced anaplatic carcinomas (giant cell type) resembling the original tumor. The HOTHC cells produced colony stimulating factor (CSF) and caused granulocytosis in the mice. PMID:17022149

    Association between autoimmune thyroiditis (CLT) and thyroid cancer remains not clear. Although both diseases often occur simultaneously in histological samples, it is not yet clear whether CLT can be regarded as a risk factor for thyroid malignancy. This review focus on the known epidemiological and molecular genetics links between both diseases. Most studies have shown a significant association between thyroid cancer and positive antibodies to thyroglobulin and histological evidence of CLT, as well. Both disorders share some risk factors (greater incidence in women, in areas with adequate supply of iodine and in patients after radiotherapy of the neck) and molecular genetics linkage. For example: RET/PTC rearrangements could be more often found in carcinomas associated with CLT, but this mutation could be found in benign lesions such as CLT, as well. CLT seems to be a positive prognostic factor in patients with differentiated thyroid cancer. It is associated with less invasive forms of tumor, lower occurrence of infiltrated lymphatic nodes and a lower risk of recurrence. PMID:26486481

    Hashimoto's thyroiditis (HT) is considered to be a risk factor for the formation of papillary carcinoma. The association of IgG4-related sclerosing disease with tumor is reported to be as sporadic cases in many organs. In this study, it was intended to re-classify the HT diagnosed cases on the basis of the existence of IgG4 (+) plasma cells; to investigate the clinicopathologic and histopathologic features of the both groups; and in addition, to evaluate the papillary carcinoma prevalence in IgG4 (+) and IgG4 (-) HT cases as well as the prognostic parameters between these groups. Totally 59 cases between the years 2008-2013, 29 of which contain Hashimoto thyroiditis diagnosis in total thyroidectomy materials, and 30 of which contain the diagnosis of HT+papillary carcinoma, were included in the study. The materials were immunohistochemically applied IgG and IgG4; and the cases were classified in two groups as IgG4-positive HT and IgG4-negative HT containing cases, on the basis of IgG4/IgG rate. All histopathologic and clinicopathologic parameters between these two groups, as well as their association with papillary carcinoma were investigated. Thirty eight (64.4%) of total 59 cases were NonIgG4 thyroiditis, and 21 (35.5%) were IgG4 thyroiditis. Tumors were detected in 14 (36.8%) of the NonIgG4 thyroiditis cases, and in 16 (76.1%) of the IgG4 thyroiditis cases. The association of IgG4 thyroiditis with tumor is statistically significant (p < 0.004). Multifocality was found to be at a higher rate in IgG4 thyroiditis cases. Perithyroidal extension was detected in six of the cases with tumor, and five of the six cases were IgG4 thyroiditis cases. The association of IgG4 (+) HT cases with increased papillary carcinoma prevalence is suggestive of that IgG4 (+) plasma cells can play a role in carcinogenesis in papillary carcinomas developed in HTs, without a chronic sclerosing ground. In addition, although the number of cases is limited, the high-association of IgG4

    N,N-dimethylacetamide, hexamethylene bisacetamide, and Polybrene induced rapid and extensive differentiation in vitro in an otherwise slowly differentiating subline of embryonal carcinoma cells. The type of differentiated cell induced was dependent on the spatial organization of the stem cells during drug treatment. In monalayer culture "epithelial" cells were produced exclusively. However, treatment of aggregated suspension cultures yielded predominantly "fibroblast-like" cells. The undifferentiated embryonal carcinoma cells and the two differentiated cell types were morphologically distinct when examined by light microscopy, scanning electron microscopy, and transmission electron microscopy; and they had differences in cell surface antigens. Both differential cell types produced large amounts of fibronectin, whereas the embryonal carcinoma cells produced only minimal amounts. This system provides a convenient way to induce relatively synchronous differentiation of embryonal carcinoma cells into specific differentiated cell types.

    The cystic mature teratomas, including dermoid cysts, are one of the most frequently occurring benign ovarian tumors diagnosed in female patients. The process of neoplastic transformation in mature dermoid cysts is applicable only to 1-2% of cases. In our article, we present a rare case of thyroid carcinoma development in adult teratoma in 21-year-old patient. The young age, certain pathomorphological features and clinical data (small size of neoplastic lesion, correct values of tumour markers, unilateral character, regular levels of thyreoglobulin and absence of any significant deviations in imaging examinations), were the basis for attempting to apply the conservative treatment both in the scope of gynecological surgery and in the supplemental endocrinological therapy. In the patient, the one-sided adnexectomy was performed, considering pathological lesions on the adnexa, as well as the other ovary dermoid cyst was enucleated, without the hysteroctomy procedure. Considering the lack of any morphological lesions and functional changes relating to thyroid gland, the treatment was not radicalised in this scope, either. At present, one year after the primary operation treatment, the patient does not manifest any disease symptoms, whereas the other ovary, in the follow-up ultrasound examinations, shows normal size and echostructure. The thyroid-stimulating hormone (TSH) suppression keeps being applied. PMID:24397359

    Cutaneous metastasis of underlying primary malignancies can present to dermatologist with chief complaints of cutaneous lesions. The underlying malignancy is generally diagnosed much later after a complete assessment of the concerned case. Medullary carcinoma thyroid (MCT) is a relatively uncommon primary neoplasia of the thyroid. Very few cases presenting as cutaneous metastases of MCT have been reported in the literature. Most of the cases which have been reported are of the papillary and the follicular types. We here report a case of a patient who presented in the dermatology clinic with the primary complaint of multiple subcutaneous nodules in anterior chest wall and left side of body of mandible. By systematic application of clinical and diagnostic skills these nodules were diagnosed as cutaneous metastasis of MCT bringing to the forefront a history of previously operated thyroid neoplasm. So clinically, the investigation of a flesh coloured subcutaneous nodule, presenting with a short duration, particularly in scalp, jaw, or anterior chest wall should include possibility of metastastic deposits. A dermatologist should keep a possibility of an internal organ malignancy in patients while investigating a case of flesh coloured subcutaneous nodules, presenting with short duration. A systematic application of clinical and diagnostic skills will eventually lead to such a diagnosis even when not suspected clinically at its primary presentation. A prompt and an emphatic diagnosis and treatment will have its bearing on the eventual outcome in all these patients. PMID:25478248

    Medullary thyroid carcinoma is the most common cause of death among patients with multiple endocrine neoplasia (MEN) 2. Dominant-activating mutations in the RET proto-oncogene have been shown to have a central role in the development of MEN 2 and sporadic medullary thyroid cancer (MTC): about half of sporadic MTCs are caused by somatic genetic changes of the RET oncogene. Inactivating mutations of the same gene lead to Hirschprung disease and other developmental defects. Thus, RET genetic changes lead to phenotypes that largely depend on their location in the gene and the function and timing of developmental expression of the RET protein. The reproducibility of the phenotype caused by each RET genotype led to MEN 2/MTC being among the first conditions in Medicine where a drastic measure is applied to prevent cancer, following genetic testing: thyroidectomy is currently routinely done in young children that are carriers of MTC-predisposing RET mutations. RET inhibitors have been also developed recently and are used in various types of thyroid and other cancers. This report reviews the RET involvement in the etiology of MEN 2 and MTC and updates the therapeutic approach in preclinical and clinical studies. PMID:17952863

    Thyroid cancer incidence is rapidly increasing. Papillary Thyroid Carcinoma (PTC), the most frequent hystotype, usually displays good prognosis, but no effective therapeutic options are available for the fraction of progressive PTC patients. BRAF and RET/PTC are the most frequent driving genetic lesions identified in PTC. We developed two complementary in vitro models based on RET/PTC1 oncogene, starting from the hypothesis that miRNAs modulated by a driving PTC-oncogene are likely to have a role in thyroid neoplastic processes. Through this strategy, we identified a panel of deregulated miRNAs. Among these we focused on miR-199a-3p and showed its under-expression in PTC specimens and cell lines. We demonstrated that miR-199a-3p restoration in PTC cells reduces MET and mTOR protein levels, impairs migration and proliferation and, more interesting, induces lethality through an unusual form of cell death similar to methuosis, caused by macropinocytosis dysregulation. Silencing MET or mTOR, both involved in survival pathways, does not recapitulate miR-199a-3p-induced cell lethality, thus suggesting that the cooperative regulation of multiple gene targets is necessary. Integrated analysis of miR-199a-3p targets unveils interesting networks including HGF and macropinocytosis pathways. Overall our results indicate miR-199a-3p as a tumor suppressor miRNA in PTC.

    Arachidonate 5-lipoxygenase (ALOX5) expression and activity has been implicated in tumor pathogenesis, yet its role in papillary thyroid carcinoma (PTC) has not been characterized. ALOX5 protein and mRNA were upregulated in PTC compared to matched, normal thyroid tissue, and ALOX5 expression correlated with invasive tumor histopathology. Evidence suggests that PTC invasion is mediated through the induction of matrix metalloproteinases (MMPs) that can degrade and remodel the extracellular matrix (ECM). A correlation between MMP-9 and ALOX5 protein expression was established by immunohistochemical analysis of PTC and normal thyroid tissues using a tissue array. Transfection of ALOX5 into a PTC cell line (BCPAP) increased MMP-9 secretion and cell invasion across an ECM barrier. The ALOX5 product, 5(S)-hydroxyeicosatetraenoic acid also increased MMP-9 protein expression by BCPAP in a dose-dependent manner. Inhibitors of MMP-9 and ALOX5 reversed ALOX5-enhanced invasion. Here we describe a new role for ALOX5 as a mediator of invasion via MMP-9 induction; this ALOX5/MMP9 pathway represents a new avenue in the search for functional biomarkers and/or potential therapeutic targets for aggressive PTC.

    Medullary thyroid carcinoma (MTC) has been described as a source of ectopic ACTH secretion in patients with Cushing’s syndrome. This is an infrequent association, occurring in less than 1% of MTC cases. Among these, it is even more unusual for an initial diagnosis of hypercortisolism to lead to the discovery of underlying MTC. Here we present a case of a patient with weakness, diarrhea, and hypokalemia who was found first to have Cushing’s syndrome and later diagnosed with metastatic MTC. The patient was treated initially with oral agents to control his hypercortisolism, then with an etomidate infusion after experiencing intestinal perforation. He also received vandetanib therapy targeting his underlying malignancy, as this has been shown to reverse clinical signs of Cushing’s syndrome in patients with MTC and subsequent ectopic ACTH secretion. Bilateral adrenalectomy was ultimately required. Medullary thyroid carcinoma should be considered in patients presenting with Cushing’s syndrome due to ectopic ACTH secretion, and a multimodality treatment approach is often required. PMID:27141514

    The present study aims to investigate the feasibility and influence of the lymphatic mapping and sentinel node biopsy on determination of the nodal status in thyroid carcinoma using blue-dye method. Nine consecutive patients with cytological diagnosis of papillary carcinoma were included in this study. To detect the sentinel lymphnode, intra- or perinodular injection of an average quantity of 0.5 ml (range : 0.1-1.2) of Ble Patenté V was performed intraoperatively in 8 cases only, as in one case a solitary cystic nodule occupied the entire lobe and thus any injection was impossible. After an average time of 16 minutes (range : 5-25) before dissection of the thyroid , no lymphnodes and no lymphatic afferent thereto visibly coloured were evidenced, except for spread of the vital dye into adjacent tissue and disrupted blood and lymphatic vessels at the injection site. Our results evidence that : intranodular injection, does not allow proper diffusion of the dye in the adjacent parenchyma, and in nodules smaller than 1 cm it may be difficult ; and that it is hazardous in cystic nodule because of the rupture risk; perinodular injection, at the four cardinal points, is impossible when the nodule occupies the entire lobe or the isthmus; multinodular goiter complicates the identification by palpation of the neoplastic nodule in which the dye should be injected or, if perinodular injection is given, to detect the parenchyma surrounding the nodule.

    Follicular thyroid lesions are the bane of cytopathology. Differentiation between adenoma and carcinoma is impossible, and often these neoplasms are indistinguishable even from uninodular goitre. In other cancers as well, a theory of stem cells as the origin of cancer has been discussed in thyroid carcinogenesis. We aimed to examine a novel stem cell associated marker identified by monoclonal antibody HESC5:3 in follicular lesions in an attempt to find a marker for differential diagnosis in thyroid cytopathology. HESC5:3 was raised against and is specific for undifferentiated human embryonic stem cells. The epitope of this novel antibody is to be defined. Immunohistochemical expression of HESC5:3 was examined in clinical material comprised of follicular neoplasms (83 adenomas, 43 carcinomas) and non-neoplastic lesions (41 goitrous, 22 hyperplastic, 23 normal tissue specimens). Staining differed significantly between neoplastic and non-neoplastic lesions. Nuclear staining was increased in non-neoplastic cells, whereas in neoplastic cells expression was mainly cytoplasmic. There was no difference between benign and malignant lesions, suggesting a role in early tumourigenesis. In conclusion, the HESC5:3 epitope may be of benefit as a neoplasia marker in distinguishing between uninodular goitre and neoplasia. Characterization of the epitope would increase the interest in this promising new stem cell associated marker. PMID:25960045

    Papillary thyroid carcinoma (PTC) is a common thyroid malignancy. Elderly patients have more severe disease and more complications following postoperative endocrine therapy to control thyroid-stimulating hormone (TSH) levels. We aimed to identify optimal postoperative serum TSH levels in elderly patients to prevent recurrence and metastasis and minimize complications. This retrospective cohort study collected data of 87 consecutive elderly patients (age >75) who underwent surgery for PTC with postoperative levothyroxine therapy (50-150 μg/d) between January 2006 and June 2008 and were followed until 2013. After 24 patients with TSH fluctuations and incomplete data were excluded, 73 patients were grouped based on postoperative TSH levels: Group A, 0.3-0.5 mIU/mL; Group B, 0.1-0.3 mIU/mL; and Group C <0.1 mIU/mL (n = 24, 25, 24, respectively). Subjects' baseline, preoperative data, postoperative complications and 1-, 3- and 5-year follow-up data were compared between groups. No significant differences in gender, age (median age of 80 years old), surgery type or clinical characteristics were found between groups (all p value >0.05). Postoperatively, all subjects had normal ECG and neck ultrasound, no osteoporosis, and no differences in survival rate or metastasis. Five-year follow-up revealed significant differences in development of arrhythmias, osteoporosis, insomnia and anxiety between Groups B (0.1-0.3 mIU/mL) and C (<0.1 mIU/mL) compared to Group A (0.3-0.5 mIU/mL). Postoperative incidence of PTC recurrence and metastasis remained stable in elderly patients undergoing thyroid surgery and endocrine therapy but complications increased significantly with increasing TSH levels. Controlling TSH to lower limits of normal may help prevent PTC recurrence and metastasis and reduce complications in this high-risk population. PMID:25744048

    Polysplenia syndrome (PSS) is a rare congenital abnormality. Metastases to spleen and skeletal muscle from differentiated thyroid cancer (DTC) are also extremely rare. Our case report aims to present an interesting case of PSS associated with splenic metastasis (SM) and skeletal muscle metastasis (SMM) from advanced papillary thyroid carcinoma which was evaluated on fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). An 84-year-old Chinese man was admitted with the history of multiple enlarged masses in bilateral neck, right axillary, and inguinal areas for >2 months. The results of ultrasonography examination were highly suggestive of malignancy. The histological results of the following biopsy were consistent with papillary thyroid carcinoma with involvement of multiple regional lymph nodes. He was referred for an FDG PET/CT imaging to evaluate the situation. FDG PET/CT showed that an intense FDG-avid thyroid mass with widespread regional lymph node involvement and distant metastases in the body. Unexpected sites of metastases were detected in the spleens and skeletal muscles. Most interestingly, FDG PET/CT imaging also described the typical imaging findings of PSS including the 2 right-sided spleens, azygos and hemiazygos continuation of inferior vena cava (IVC), right-sided stomach, middle line liver, a short pancreas, preduodenal portal vein (PPV), and malrotation of gut. Whole body FDG PET/CT imaging can accurately evaluate the situation of DTC by detecting regional lymph node involvement, common and rare sites of distant metastases which are closely related to staging, management, and prognosis of this disease. Whole-body FDG PET/CT is also valuable in demonstrating the typical imaging features of PSS. PMID:26825891

    Recent Phase III data presented at the American Society of Clinical Oncology (ASCO) 2013 annual conference by Brose et al led to the US Food and Drug Administration (FDA) approval of sorafenib for the treatment of well-differentiated radioactive iodine-resistant metastatic thyroid cancer. This is the second drug in 40 years to be FDA approved for this indication. Recent reviews and a meta-analysis reveal a modest ability to induce a partial remission but substantial ability to halt disease progression. Given the significant activating mutations present in thyroid cancer, many of which are inhibited by sorafenib, the next logical approach may be to combine targeted rational therapies if permitted by collective toxicity profiles. This systematic review aims to summarize the recent Phase II/III data leading to the FDA approval of sorafenib for radioactive iodine therapy differentiated thyroid cancer and highlights recent novel combination therapy trials.

    Thyroid carcinoma is the most common endocrine malignancy, and papillary thyroid carcinoma represents the most common thyroid cancer. Papillary thyroid carcinomas that invade locally or metastasize are associated with a poor prognosis. We found that, during epithelial–mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1), papillary thyroid carcinoma cells acquired increased cancer stem cell-like features and the transcription factor paired-related homeobox protein 1 (PRRX1; alias PRX-1), a newly identified EMT inducer, was markedly up-regulated. miR-146b-5p was also transiently up-regulated during EMT, and in siRNA experiments miR-146b-5p had an inhibitory role on cell proliferation and invasion during TGF-β1–induced EMT. We conclude that papillary thyroid carcinoma tumor cells exhibit increased cancer stem cell-like features during TGF-β1–induced EMT, that miR-146b-5p has a role in cell proliferation and invasion, and that PRRX1 plays an important role in papillary thyroid carcinoma EMT and disease progression.

    In this study, we examined the molecular mechanism of thyroid carcinoma (THCA) using bioinformatics. RNA-sequencing data of THCA (N = 498) and normal thyroid tissue (N = 59) were downloaded from The Cancer Genome Atlas. Next, gene expression levels were calculated using the TCC package and differentially expressed genes (DEGs) were identified using the edgeR package. A co-expression network was constructed using the EBcoexpress package and visualized by Cytoscape, and functional and pathway enrichment of DEGs in the co-expression network was analyzed with DAVID and KOBAS 2.0. Moreover, modules in the co-expression network were identified and annotated using MCODE and BiNGO plugins. Small-molecule drugs were analyzed using the cMAP database, and miRNAs and transcription factors regulating DEGs were identified by WebGestalt. A total of 254 up-regulated and 59 down-regulated DEGs were identified between THCA samples and controls. DEGs enriched in biological process terms were related to cell adhesion, death, and growth and negatively correlated with various small-molecule drugs. The co-expression network of the DEGs consisted of hub genes (ITGA3, TIMP1, KRT19, and SERPINA1) and one module (JUN, FOSB, and EGR1). Furthermore, 5 miRNAs and 5 transcription factors were identified, including E2F, HSF2, and miR-26. miR-26 may participate in THCA by targeting CITED1 and PLA2R1; E2F may participate in THCA by regulating ITGA3, TIMP1, KRT19, EGR1, and JUN; HSF2 may be involved in THCA development by regulating SERPINA1 and FOSB; and small-molecule drugs may have anti-THCA effects. Our results provide novel directions for mechanistic studies and drug design of THCA. PMID:26985959

    To develop novel therapies for aggressive thyroid cancers, we have synthesized a collection of histone deacetylase (HDAC) inhibitor analogs named AB1 to AB13, which have different linkers between a metal chelating group and a hydrophobic cap. The purpose of this study was to screen out the most effective compounds and evaluate the therapeutic efficacy. AB2, AB3 and AB10 demonstrated the lowest half-maximal inhibitory concentration (IC50) values in one metastatic follicular and two anaplastic thyroid cancer cell lines. Treatment with each of the three ABs resulted in an increase in apoptosis markers, including cleaved poly adenosine diphosphate ribose polymerase (PARP) and cleaved caspase 3. Additionally, the expression of cell-cycle regulatory proteins p21(WAF1) and p27(Kip1) increased with the treatment of ABs while cyclin D1 decreased. Furthermore, AB2, AB3 and AB10 were able to induce thyrocyte-specific genes in the three thyroid cancer cell lines indicated by increased expression levels of sodium iodide symporter, paired box gene 8, thyroid transcription factor 1 (TTF1), TTF2 and thyroid-stimulating hormone receptors. AB2, AB3 and AB10 suppress thyroid cancer cell growth via cell-cycle arrest and apoptosis. They also induce cell re-differentiation, which could make aggressive cancer cells more susceptible to radioactive iodine therapy. PMID:26251030

    Ultrasound elastography has been a very useful tool in predicting the risk of malignant thyroid tumor for several years. The objective of this study was to determine if there is a correlation between strain ratio (SR), collagen deposition and transforming growth factor β1 (TGF-β1) expression in different types of thyroid nodules and if TGF-β1 is related to cervical lymph node metastasis. 102 nodules from 81 patients who underwent thyroid resection surgery in our hospital were retrospectively studied. All of these patients had undergone ultrasound elastography scanning before surgery. Masson staining and immunohistochemical staining were used to evaluate the ratio of expression of collagen deposition and TGF-β1. There was a significant difference between benign and malignant thyroid nodules in SR (8.913 ± 11.021 vs. 1.732 ± 0.727, p = 0.000), collagen content (0.371 ± 0.125 vs. 0.208 ± 0.057, p = 0.000) and TGF-β1 expression (0.336 ± 0.093 vs. 0.178 ± 0.071, p = 0.000). A cutoff of 2.99 for SR measurement was selected for the highest Youden index for predicting malignant thyroid nodules, which yielded 87.88% sensitivity, 100% specificity, 100% positive predictive value, 83.72% negative predictive value and 92.15% accuracy. Expression of collagen and TGF-β1 was positively correlated with SR measurements (coefficient = 0.839 for collagen and 0.855 for TGF-β1, p = 0.000). Among 61 nodules with papillary thyroid carcinoma, the average SR for the metastasis group was higher than that for the non-metastasis group (10.955 ± 13.805 and 7.852 ± 7.931, respectively), but without statistical significance (p = 0.287). Collagen deposition was significantly higher in the metastasis group than in the non-metastasis group (0.421 ± 0.091 vs. 0.353 ± 0.118, p = 0.011). TGF-β1 expression was also significantly higher in the metastasis group than in the non-metastasis group (0.378 ± 0.0.69 vs. 0.328 ± 0.091, p = 0.016). To conclude, TGF-β1 may contribute to thyroid

    Background The incidence of differentiated thyroid carcinoma (DTC) is low in people of African origin and higher in populations living on islands, but there is no well-established explanation for these differences. Cuba is a multiethnic nation with people of African and Spanish descent. Until now, no study on the risk factors of DTC has focused on the Cuban population. Our aim is to establish the role of environmental and lifestyle factors and to relate anthropometric measurements to the risk of developing DTC in Cuba. Methods We performed a case-control study of 203 DTC patients treated in two hospitals in Havana and 212 controls living in the area covered by these hospitals (i.e. parts of Havana and the municipality of Jaruco). Risk factors were analyzed using conditional logistic regression. Results As has been shown by other studies, we found that non-African ethnicity, never smoking, parity, and high body mass index are risk factors significantly associated with DTC, whereas a history of exposure to ionizing radiation and level of education were not significantly related with disease development. Being rhesus factor-positive, having a personal history of benign thyroid disorder, agricultural occupation, and consumption of artesian well water were also associated with a significantly increased risk of developing DTC. Conclusions The original findings reported here concern the risk of DTC that was associated with non-African ethnicity, positive rhesus factor, farming, and drinking water from an artesian well.

    In order to estimate the effects of small interfering RNA (siRNA) targeting retinoblastoma binding protein 2 (RBP2) on the proliferation, expression, invasion, migration and tumorigenicity abilities of papillary thyroid carcinoma K1 cells, siRNA targeting RBP2 (RBP2-siRNA) and negative control siRNA were transfected into K1 cells. The mRNA levels of RBP2 in the transfected cells were estimated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and the protein levels of RBP2 in these cells were evaluated by western blot analysis and immunocytochemical (ICC) analyses. The growth, tumorigenicity, migration and invasion abilities of the transfected cells were measured by Cell Counting Kit-8 (CCK-8), soft agar colony formation and transwell chamber assay, respectively. The ICC results demonstrated that the protein expression levels of RBP2 were lower in the RBP2-siRNA-transfected cells than in the blank and control cells (analysis of variance, F=26.754, P<0.01). RBP2-siRNA downregulated RBP2 at the mRNA (t=8.869) and protein level (F=60.835) (P=0.000 vs. control cells). In addition, the transfection of RBP2-siRNA into K1 cells also suppressed cell proliferation at 24, 48 and 72 h post-transfection (t=7.650, P<0.01; t=2.606, P=0.016; and t=2.377, P=0.027, respectively). Compared with the control group, the number of invasive and migrated cells were significantly reduced in the RBP2-siRNA-transfected group (t=4.774 and t=6.366, respectively; P<0.01). Furthermore, the tumorigenic potential of the cells transfected with RBP2-siRNA was markedly reduced, as indicated by the soft agar formation assay (t=2.749, P=0.014 vs. control cells). In conclusion, the transfection of RBP2-siRNA into papillary thyroid carcinoma K1 cells suppressed the expression of RBP2 in these cells, and reduced their proliferation, invasion, migration and tumorigenic potential. Therefore, targeting RBP2 may be an efficient approach to control thyroid carcinoma. PMID:26788140

    Background Recurrent non-medullary thyroid carcinoma (NMTC) is a rare disease. We initially characterized 27 recurrent NMTC: 13 papillary thyroid cancers (PTC), 10 oncocytic follicular carcinomas (FTC-OV), and 4 non-oncocytic follicular carcinomas (FTC). A validation cohort composed of benign and malignant (both recurrent and non-recurrent) thyroid tumours was subsequently analysed (n = 20). Methods Data from genome-wide SNP arrays and flow cytometry were combined to determine the chromosomal dosage (allelic state) in these tumours, including mutation analysis of components of PIK3CA/AKT and MAPK pathways. Results All FTC-OVs showed a very distinct pattern of genomic alterations. Ten out of 10 FTC-OV cases showed near-haploidisation with or without subsequent genome endoreduplication. Near-haploidisation was seen in 5/10 as extensive chromosome-wide monosomy (allelic state [A]) with near-haploid DNA indices and retention of especially chromosome 7 (seen as a heterozygous allelic state [AB]). In the remaining 5/10 chromosomal allelic states AA with near diploid DNA indices were seen with allelic state AABB of chromosome 7, suggesting endoreduplication after preceding haploidisation. The latter was supported by the presence of both near-haploid and endoreduplicated tumour fractions in some of the cases. Results were confirmed using FISH analysis. Relatively to FTC-OV limited numbers of genomic alterations were identified in other types of recurrent NMTC studied, except for chromosome 22q which showed alterations in 6 of 13 PTCs. Only two HRAS, but no mutations of EGFR or BRAF were found in FTC-OV. The validation cohort showed two additional tumours with the distinct pattern of genomic alterations (both with oncocytic features and recurrent). Conclusions We demonstrate that recurrent FTC-OV is frequently characterised by genome-wide DNA haploidisation, heterozygous retention of chromosome 7, and endoreduplication of a near-haploid genome.

    Follicular variant of papillary thyroid carcinoma (FVPTC) creates a continuous diagnostic dilemma among pathologists because of the paucity of nuclear changes of papillary carcinoma and overlapping features with benign and other neoplastic follicular lesions. Current guidelines for the management of thyroid nodules recommend surgery for confirmed PTC, suspicious for PTC, and follicular neoplasm cases, while further immediate diagnostic studies or treatment are not routinely required if the nodule is benign on cytology. This study is designed to determine the accuracy of cytology in the diagnosis of FVPTC, based on the Bethesda classification system, and determine the implications for patient management based on the current recommendation. Based on a retrospective review of cytologic diagnoses between January 2008 and December 2011, thyroid fine needle aspiration (FNA) cytology specimens with subsequent surgical intervention and a final diagnosis of FVPTC were selected. The cytologic diagnoses were compared with the final diagnoses, and the percentage of cases contributing to the final diagnosis of FVPTC was calculated for each diagnostic category. Triage efficiency and diagnostic accuracy were calculated. One hundred and fifty-two cases with histologic confirmation of FVPTC were identified (representing 128 patients-101 female, 27 male). All patients had undergone either lobectomy with completion thyroidectomy or total thyroidectomy. The cytologic diagnosis of "positive for malignancy" accounted for only 27 % of the final histologic diagnosis of FVPTC, while suspicious for carcinoma, follicular neoplasm, follicular lesion of undetermined significance, and benign accounted for 11, 23, 23, and 16 % of the final diagnosis of FVPTC, respectively. Only 18 % of the 55 cases tested were positive for BRAF mutation. The subtle nuclear features of FVPTC pose challenges for an accurate diagnosis. Therefore, a better approach is to triage these cases for surgical intervention

    Transformation of the thyroid cell line FRTL-5 results in loss or reduction of differentiation as measured by the expression of thyroglobulin and thyroperoxidase, two proteins whose genes are exclusively expressed in thyroid follicular cells. The biochemical mechanisms leading to this phenomenon were investigated in three cell lines obtained by transformation of FRTL-5 cells with Ki-ras, Ha-ras, and polyomavirus middle-T oncogenes. With the ras oncogenes, transformation leads to undetectable expression of the thyroglobulin and thyroperoxidase genes. However, the mechanisms responsible for the extinction of the differentiated phenotype seem to be different for the two ras oncogenes. In Ki-ras-transformed cells, the mRNA encoding TTF-1, a transcription factor controlling thyroglobulin and thyroperoxidase gene expression, is severely reduced. On the contrary, nearly wild-type levels of TTF-1 mRNA are detected in Ha-ras-transformed cells. Furthermore, overexpression of TTF-1 can activate transcription of the thyroglobulin promoter in Ki-ras-transformed cells, whereas it has no effect on thyroglobulin transcription in the Ha-ras-transformed line. Expression of polyoma middle-T antigen in thyroid cells leads to only a reduction of differentiation and does not severely affect either the activity or the amount of TTF-1. Another thyroid cell-specific transcription factor, TTF-2, is more sensitive to transformation, since it disappears in all three transformed lines, and probably contributes to the reduced expression of the differentiated phenotype.

    Sorafenib has an antitumor activity in patients with radioactive iodine-refractory differentiated thyroid carcinoma (RAIR-DTC). Prior research has implicated signaling through the MAPK and AKT/PI3K pathways in the progression of DTC. To assess whether the activity of these pathways is predictive of response to sorafenib, we retrospectively studied molecular tumor markers from these two pathways from a phase 2 study of sorafenib in RAIR-DTC. Tumor samples from 40 of 53 DTC subjects obtained prior to initiation of sorafenib were immunostained with DAB-labeled antibodies to phospho-AKT (pAKT), phospho-ERK (pERK), and phospho-S6 (pS6). BRAFV600E genetic mutation analysis was performed on all samples. Expression levels and mutational status were compared to response and progression-free survival (PFS) for each patient. Low tumor expression of nuclear pAKT was associated with partial response to sorafenib (p < 0.01). Patients with nuclear pAKT expression that was below the median for our sample were more than three times as likely to have a partial response as patients with equal to or above median expression. There was no correlation between tumor expression of nuclear pERK or pS6 and response. Endothelial cell and pericyte expression of pERK, pAKT, and pS6 were not predictive of response. There was no correlation between BRAFV600E mutation status and partial response. No correlation was observed between either the expression of pAKT, pERK, or pS6, or the presence of the BRAFV600E mutation, and PFS. In conclusion, lower tumor expression of nuclear pAKT was associated with higher rate of response to sorafenib. This observation justifies evaluation of combination therapy with sorafenib and an inhibitor of the PI3K/AKT signaling pathway in RAIR-DTC. PMID:26994002

    Despite the publication of a recent meta-analysis of elastography in thyroid nodules, further work is necessary on this issue in different populations. In this study, we aimed to evaluate the clinical value of elastography on nodular goiters in mild iodine-deficient regions without excluding patients according to nodule characteristics. This prospective study was conducted between April 2010 and December 2011 in Yıldırım Beyazıt Dıskapı Research Hospital Endocrinology outpatient clinic. Five hundred twenty-eight nodular goiter patients who underwent thyroid fine-needle aspiration biopsy were included in our study. Elastography scores and indexes were measured with real-time ultrasound elastography (Hitachi® EUB 7000 HV machine with 13 MHz linear transducer). There were 471 females and 57 males and their ages ranged from 45 years to 78 years. A total of 601 nodules were evaluated in these patients. The area under the curve (AUC) for the elasto score was 0.91 (p < 0.0001) and AUC for the strain index (SI) was 0.96 (p < 0.0001). We suggest that the SI reflects malignancy better than the elasto score. We conclude that elastography scores greater than 3 have 76% sensitivity and 96% specificity for diagnosing malignancy. For SI, we conclude that 3.75 (83% sensitivity and 95% specificity) is the cutoff point. Elasto score and SI measurements of thyroid nodules in our population are efficient and increase the diagnostic performance of the sonography. PMID:25161183

    A 3-yr-old African pygmy hedgehog (Atelerix albiventris) was submitted with dysphagia, weight loss, and tetraparesis. A palpable mass was found on the ventral neck. Histologic examination revealed replacement of the thyroid gland by a highly cellular, expansile, and infiltrative mass composed of lobules of polygonal cells separated by fine fibrovascular septa. Examination of ultrathin sections revealed tumor cells with few to many dense-core neuroendocrine granules, approximately 100-200 nm in diameter, and stromal amyloid. Immunohistochemical stains were positive for neuron-specific enolase. Only rare cells had positive immunohistochemical staining for calcitonin. Findings are consistent with a neuroendocrine tumor of C-cell origin. This is the first report of a C-cell carcinoma in a hedgehog. PMID:12564541

    Accumulating evidence suggests that some microRNAs (miRNAs) are involved in papillary thyroid carcinoma (PTC) progression. However, it remains necessary to elucidate the underlying molecular mechanisms involved. In the present study, we investigated the role of microRNA-101 (miR-101) in PTC via targeting of Ras-related C3 botulinum toxin substrate 1 (Rac1). The results showed that miR-101 was significantly downregulated in PTC tissues compared with adjacent normal tissues. Restoration of miR-101 expression significantly inhibited cell proliferation in the K1 PTC cell line. Moreover, algorithm-based and experimental strategies verified Rac1 as a direct target of miR-101 in the K1 cell line. Taken together, these findings suggest that miR-101 inhibited PTC growth via the downregulation of Rac1 expression, providing a better understanding of miRNA-modulated signaling networks for future cancer therapeutics.

    Monostotic fibrous dysplasia of the vertebra is a rare entity. A case of a 53-year-old lady who presented with an 8 months history of pain in the thoracic spine region with paraparesis is discussed. She had a history of papillary thyroid carcinoma and had undergone total thyroidectomy one year prior to her current problem. Magnetic resonance imaging revealed isolated osteolytic lesion over the posterior element of the T12 vertebra with narrowing of the spinal canal causing compression of the cord. The diagnosis of fibrous dysplasia was made histologically. Fibrous dysplasia rarely occurs in axial bones compared with peripheral bones. This case illustrates that osteolytic lesion of the vertebrae should be evaluated with detailed radiological and histopathological examination before an empirical diagnosis of spinal metastasis is made in an adult with a background history of primary malignancy well-known to spread to the bone.

    Anaplastic thyroid carcinoma (ATC) is one of the most aggressive malignancies and prognostic outlook remains very dismal. Treatment most often is palliative in intent attempting to relieve the patients from local compressive symptoms in the neck. Radical surgery, radiotherapy (RT), and chemotherapy have not been tested in large prospective trials, and current evidence from retrospective series and small trials indicate only marginal survival benefits. Given the poor prognostic and therapeutic outlook, patients must be encouraged to be actively involved in the decision making process. We report the case of an elderly patient who had no response to palliative RT, and was treated with oral metronomic chemotherapy. The response to oral metronomic chemotherapy was dramatic, and the patient has enjoyed complete freedom from symptoms as well as radiologically exhibits a complete regression. Thus, we document the first ever use of a simple, cost-effective, and convenient oral metronomic chemotherapeutic regimen delivering a remarkable response in an elderly patient with ATC.

    There is a low incidence of multiple primary cancer, particularly when the cancer is synchronous. The present report presents a case of synchronous double primary malignancies. A 58-year-old woman was admitted to Ling Nan Hospital (Guangzhou, China) complaining of pain in the left hip. X-ray revealed an osteolytic lesion and further examination indicated the presence of double primary cancer, consisting of hepatic cholangiocarcinoma and thyroid carcinoma. Biopsy of the osteolytic lesion showed a metastatic adenocarcinoma of unknown origin. Subsequently, final diagnosis was confirmed by I-131 scan and liver lesion biopsy. The patient received positive multidisciplinary treatments and survived for 9 months following diagnosis. The results of the present case suggest that multiplicity of primary malignancy is not necessarily an indicator of poor prognosis, as long as effective diagnosis and adequate disease management are achieved.

    The objective of the current study was to investigate the significance and biologic characteristic of neuroendocrine cell differentiation (NED) in gastric carcinoma by comparing the prognosis and clinicopathologic characteristics between patients with or without NED. Retrospective analyses of neuroendocrine markers, neuron specific enolase (NSE), chromogranin A (CgA), and synaptophysin (Syn) were performed in 174 human gastric carcinoma patients. NED association was found in 21.3% gastric carcinoma patients, with or without NED, and was correlated with tumor location, cancer emboli, infiltrative depth, TNM stage and distant metastasis (P < 0.05 in each case). The 1-year and 3-year survival rate of the patients who suffered from gastric carcinoma with NED were significantly lower than those without NED. The overall survival time of patients with NED was shorter than those with gastric carcinoma without NED, with a significant difference between the two types (P = 0.037). Cumulatively, gastric carcinoma patients with NED had shorter postoperative survival time and poorer prognosis. PMID:26221337

    Background: Intramedullary spinal cord metastases (IMSCM) are typically drop lesions from intracranial metastases and are a rare manifestation of systemic malignancy (8.5% of central nervous system metastases). They arise from primaries such as the lungs, breast, kidney, melanoma, or lymphoma. On the other hand, they arise very rarely from papillary thyroid carcinoma (PTC), even though it is the most common type of primary thyroid malignancy. Case Description: A 54-year-old male presented with pain in the lower back along with tingling, numbness, and weakness in the bilateral lower limbs. This was associated with urine incontinence for 1½ months. In the previous month, he developed a left-sided solitary thyroid nodule. Fine needle aspiration cytology and ultrasonography were suggestive of metastasis. Furthermore, the thoracolumbar magnetic resonance imaging showed T1-hypo and T2-hyper-intense D11-D12 level intramedullary lesion, with intense enhancement, which was consistent with an intramedullary lesion involving the conus. At surgery, a firm, brownish yellow, friable, vascular tumour was removed en toto. Upon discharge, the patient was neurologically intact except for residual bladder incontinence. Conclusion: In an extensive literature review (pubmed), IMSCM metastasis from PTC primary is confirmed as a rarity and this may be the fourth documented case. Moreover, this may be the first report of a case of PTC metastatic neurological deterioration “even before the treatment of the primary was undertaken.” Early diagnosis and microsurgical
