    Full Text Available INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas. We have read, analysed and compare available reviews and original articles investigating different etiological factors in the development of thyroid carcinomas through Google Scholar and PubMed Database. DISCUSSION: Aetiology involved in the development of thyroid carcinomas is multifactorial and includes external influences, as well as constitutional predispositions and genetic etiological factors. The actual effect of environmental and constitutional factors is on promoting genetic and epigenetic alterations which result in cell proliferation and oncogenesis. Until now are identified numerous genetic alterations, assumed to have an important role in oncogenesis, with MAPK and PI3K-AKT as crucial signalling networks regulating growth, proliferation, differentiation and cell survival/apoptosis. CONCLUSION: This new molecular insight could have a crucial impact on diagnosis and also on improving and selecting an appropriate treatment to the patients with thyroid malignancies.

    We have adopted for the follow up of the differentiated thyroid carcinomas in adult cases, a protocol of control which is at the same time strict and not very constraining for the patient and which is based on two types of investigations. Most of your patients have been, at first, submitted for a total thyroidectomy which is followed with one or many therapeutic doses of 3700 MBq (100 mCi) of 131-Iodine and that to destroy thewhole of the thyroid tissue. The patients are then reexamined every six months and are submitted for a T4 opotherapeutic treatment the balance of a general check-up which includes a delicate clinic control, radiologic exam and biological exam, a general control of thyroid hormones, of the T.S.H. and the thyroglobulin and the antithyroglobulin antibodies. In case of any doubt, the balance sheet must be stopped and the patient which is suspected of having Iodine desaturation is submitted for a new general clinic and biologic check-up, which is accompanied with a total scanning after oral administration of 185 mBq (5 mCi) 131-Iodine. If this general check-up shows any active nodul, another therapeutic decision is taken which is often based on an new carcinologic dose of 131-Iodine. This treatment is always followed with a post therapeutic scanning 2 and 5 days later and than another new general check-up three months later to judge the efficiency of the treatment, and during this time the patient is compensed with a LT3.

    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 (99m)TcO4 (-) 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 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.

    Background: Anaplastic thyroid carcinoma is rare but is one of the most aggressive malignancies. Therefore, accurate diagnosis is important in order to provide appropriate therapy. Purpose: To establish useful computed tomographic (CT) criteria for differentiating anaplastic carcinoma from other thyroid masses. Material and Methods: The CT scans of nine patients with anaplastic carcinomas were retrospectively reviewed and compared with those of 32 patients with papillary carcinomas (n = 12) or benign lesions (n = 20) exceeding a maximum diameter of 2.0 cm. Image analysis was performed according to the following CT parameters: size, margin (well defined or ill defined), composition (cystic, mixed, or solid), mean attenuation value, ratio of attenuation of the mass to that of the adjacent muscle (M/m attenuation ratio), necrosis (present or absent), and calcification (stippled, nodular, or absent) of the thyroid mass; and tumor-spreading patterns including the presence of surrounding normal thyroid tissue in the involved lobe, involvement of the contralateral thyroid lobe, extension into the adjacent structures, and cervical lymphadenopathy. Results: Anaplastic carcinomas appeared as large (average 4.6 cm), solid (100%), and ill-defined (88.9%) masses accompanied by necrosis (100%), nodular calcification (44.4%), direct invasion into the adjacent organs (55.6%), and cervical lymph node involvement (77.8%). Tumor necrosis was the most valuable parameter in differentiating anaplastic carcinomas from other thyroid masses. Patient age (>70 years) and low attenuation value on postcontrast scan (attenuation value <100 HU, or M/m attenuation ratio <1.3) are also helpful predictors for anaplastic carcinoma. Conclusion: If a patient is older than 70 years of age and has a large necrotic thyroid mass of low attenuation, anaplastic carcinoma should be included in the differential diagnosis

    The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival of patients by 50%. Bone metastases represent a frequent complication especially of follicular thyroid cancer and severely reduce the quality of life causing pain, fractures, and spinal cord compression. Diagnosis is established by correlating clinical suspicion with imaging. Imaging is essential to detect, localize, and assess the extension of the lesions and should be used in conjunction with clinical evidence. Bone metastases are typically associated with elevated markers of bone turnover, but these markers have not been evaluated in differentiated thyroid cancer. Skeletal and whole-body magnetic resonance imaging and fusion 2-deoxy-2-[18F]fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) are the best anatomic and functional imaging techniques available in specialized centers. For well-differentiated lesions, iodine-PET scan combined (124)I-PET/CT is the newest imaging development and (131)I is the first line of treatment. Bisphosphonates reduce the complications rate and pain, alone or in combination with radioiodine, radionuclides, or external beam radiotherapy and should be employed. Surgery and novel minimally invasive consolidation techniques demand an appropriate patient selection for best results on a multimodal approach. Basic research on interactions between tumor cells and bone microenvironment are identifying potential novel targets for future more effective therapeutic interventions for less differentiated tumors.

    The incidence of Well-differentiated Thyroid Carcinoma (WDTC) has been increasing over the past several decades. Consequently, so has the incidence of recurrence, which ranges from 15% to 30%. Factors leading to increased risk of recurrence are well described. However, the impact of local and regional recurrence is not well understood, but distant recurrence dramatically reduces 10-year survival to 50%. Recurrent WDTC has several established options for treatment; Observation, Radioactive Iodine (RAI), Surgery and External Beam Radiotherapy (EBRT). Novel treatments such as radiofrequency ablation (RFA) and percutaneous ultrasound-guided ethanol injection (PUEI) are beginning to gain popularity and have promising early results. A review of the current literature, outcome measurements and a strategy for revision surgery within the central neck compartment are discussed within this manuscript.

    Full Text Available 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.

Standard therapy for most patients with localized differentiated thyroid cancer (DTC includes surgery, radioactive iodine, and thyroid hormone replacement. A minority of thyroid cancer patients requires systemic therapy for metastatic disease. Patients with metastatic DTC do not usually benefit from traditional cytotoxic chemotherapy. In this review, we describe newly developed small-molecule tyrosine kinase inhibitors (TKIs that are being actively tested and used in the management of advanced thyroid cancer. The use of TKIs as a form of molecular targeted therapy is evolving based on understanding of the pathways involved in DTC. Disrupting tumor vascular supply by targeting vascular endothelial growth factor receptor signaling is the most commonly used approach to treat advanced/metastatic DTC. Other mechanisms include targeting BRAF, MAPK/ERK kinase, or mammalian target of rapamycin signaling. Although TKIs appear to have superior efficacy compared to cytotoxic chemotherapy, they can cause substantial adverse effects; symptomatic management of adverse effects, dose adjustment, or cessation of therapy may be required.

    Thyroid gland presents a wide spectrum of tumours derived from follicular cells that range from well differentiated, papillary and follicular carcinoma (PTC and FTC, respectively), usually carrying a good prognosis, to the clinically aggressive, poorly differentiated (PDTC) and undifferentiated thyroid carcinoma (UTC).It is usually accepted that PDTC and UTC occur either de novo or progress from a pre-existing well differentiated carcinoma through a multistep process of genetic and epigenetic changes that lead to clonal expansion and neoplastic development. Mutations and epigenetic alterations in PDTC and UTC are far from being totally clarified. Assuming that PDTC and UTC may derive from well differentiated thyroid carcinomas (WDTC), it is expected that some PDTC and UTC would harbour genetic alterations that are typical of PTC and FTC. This is the case for some molecular markers (BRAF and NRAS) that are present in WDTC, PDTC and UTC. Other genes, namely P53, are almost exclusively detected in less differentiated and undifferentiated thyroid tumours, supporting a diagnosis of PDTC or, much more often, UTC. Thyroid-specific rearrangements RET/PTC and PAX8/PPARγ, on the other hand, are rarely found in PDTC and UTC, suggesting that these genetic alterations do not predispose cells to dedifferentiation. In the present review we have summarized the molecular changes associated with the two most aggressive types of thyroid cancer.

    Radioactive iodine therapy has evolved over the past 70 years from treatment of known metastatic thyroid carcinoma to include adjuvant use to decrease the incidence of recurrent disease and to ablation of normal remnant tissue following thyroidectomy, even for minimal tumor involvement. Advances in laboratory testing, development of drugs useful in radioiodine treatment, as well as advances in radiation detection and imaging instrumentation, have progressively improved the utility of radioiodine therapy of differentiated thyroid carcinoma. Guidelines have proliferated and they have become more detailed and complex. This trend is likely to continue as the science and technology involved increases in sophistication and efficacy.

    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.l ± 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.

The history of nodular or diffuse goiter is closely related to risk of thyroid carcinoma. On account of the function of the thyroid gland, many studies focus on iodine intake.The aim of the study was to assess whether dietary patterns could be risk factors of differentiated thyroid carcinoma.Material/Methods:The case-control study was based on a questionnaire, which included information about dietary patterns and was carried out on 284 patients comprising 30 males (mean age 58.4±13.7 years, and 254 females (mean age 52.1±13.8 years, as well as 345 randomly selected controls: 58 males (mean age 60.2±12 years and 287 females (mean age 53.4±14.3 years randomly selected from the Population Register and adjusted by age and gender to the group of TC. The main groups of nutritional products, i.e. starchy foods, meat, dairy products, vegetables, fruits, and beverages, were analyzed.Results:Consumption of vegetables, fruits, saltwater fish and cottage cheese was significantly lower in patients with differentiated thyroid carcinoma than in controls, quite the contrary to starchy foods, especially white bread.Conclusions:Dietary patterns appear to modify the risk of thyroid carcinoma. A diet rich in vegetables and fruit, as well as saltwater fish (a source of iodine and low-fat meat, could be an important protective factor.

    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.

    Full Text Available Background: Using of CD10 in accordance with clinical and histological features of thyroid lesions could be used as both diagnostic and prognostic tool, which consequently influence the management and their prognosis for survival of patients with thyroid neoplasms especially papillary thyroid carcinoma (PTC. The aim of this study was to determine its expression in PTC and different benign thyroid lesions. Materials and Methods: In this descriptive-analytic, cross-sectional study, paraffin-embedded tissues of patients with definitive pathologic diagnosis of different benign thyroid lesions and PTC were retrieved. Immunostained sections of each slides was performed using immunohistochemistry methods and expression of CD10 was compared in two groups of benign thyroid lesions and PTC. Results: From selected cases 134 sections studied in two groups of PTC (n = 67 and benign thyroid lesions (n = 67. CD10 were immunohistochemically positive in 29.9% of PTC cases, but in none of the thyroid benign lesions (0% (P 0.05. Conclusion: The results of the current study indicate that due to the higher expression of CD10 in PTC than benign thyroid lesions it might be used for differentiating mentioned lesions. But for using it as a diagnostic tool further studies with larger sample size and determination of its sensitivity, specificity and cut-off point is necessary.

    Thyroid carcinomas and lung adenocarcinoma share cytomorphological features yet have different prognoses. Thyroid Transcription Factor-1 (TTF-1) is an immunohistochemical (IHC) marker used to confirm pulmonary and thyroid carcinoma, while Thyroglobulin (TGB) is expressed by thyroid carcinoma. The cytopathology archive of The Johns Hopkins Hospital was searched for cases of lung adenocarcinoma versus thyroid carcinoma with TTF-1 and TGB IHC. Forty-four cases of lung adenocarcinoma (25) and thyroid carcinoma (19) were retrieved. One was metastatic lung adenocarcinoma to the thyroid and three were metastatic papillary thyroid carcinoma (PTC) to the lung. The initial interpretation of two cases from bony lesions was metastatic lung adenocarcinoma. In light of additional clinical information and TGB immunostain, the diagnoses of these two cases changed to metastatic thyroid carcinoma. TTF-1 and TGB is a small immunostain panel that can differentiate lung adenocarcinoma from thyroid carcinoma and prevent misdiagnosis and its consequences. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available Introduction. Thyroglobulin is composed glycoprotein, and it is synthesized by follicular cells of the thyroid gland. Treatment of differentiated thyroid carcinomas involves total thyroidectomy followed by radioiodine ablation of a potential remaining tissue. The measurement of thyroglobulin in the postoperative follow-up can serve as an indicator of tumor growth or recurrence of the disease. Objective. The aim of this paper is to examine the value of thyroglobulin in patients surgically treated for differentiated thyroid cancer who had metastases in the lymph nodes of the neck, as well as in operated on patients without any evident metastasis. Methods. Thyroglobulin values in the serum of 58 patients were analyzed. Two groups were formed. The thyroglobulin value was established with the use of IRMA-hTg (125I system. Normal levels of thyroglobulin were from 2 ng/ml to 65 ng/ml. For all of 58 patients, thyroglobulin was determined three times. The first, so-called pre-ablation thyroglobulin was determined immediately before the application of 131I ablation dose. The second and the third measurements were conducted six to eight months and one year, respectively, after the application of the ablation dose respectively. Results. The first group consisted of 14 patients with histologically proven metastases in the lymph nodes of the neck, while the second group consisted of 44 patients without any evident metastases. The average thyroglobulin value of pre-ablation in the patients from the first group was 43.45 ng/ml, while in the second was 7.57 ng/ml. Levene’s test (with p = 0.00, i.e p < 0.05, demonstrated a statistically significant difference. Furthermore, in both groups, there was statistically significant difference between pre-ablation and post-ablation thyroglobulin values (Student’s t-test with p < 0.05. Conclusion It can be concluded that the average value of thyroglobulin was significantly higher in patients with lymph node metastases

    Background and Purpose: The indication for adjuvant postoperative radiotherapy in patients with differentiated thyroid carcinoma (DTC) extending beyond the thyroid capsule has been an issue of controversy during the past 2 decades. No randomized studies evaluating the benefit of radiotherapy have been published so far. In the Multicenter Study Differentiated Thyroid Carcinoma (MSDS), a randomization has been performed concerning external-beam radiotherapy in patients with DTC extending beyond the thyroid capsule (pT4 pN0/1/ x cM0, TNM classification, 5th edition, 1997) following surgery and radioiodine therapy. Radiation-associated toxicity has been prospectively evaluated. Patients and Methods: Radiotherapy was performed with 50.4 Gy (pN1) or 54.0 Gy (pN1/x) to the cervical, supraclavicular and upper mediastinal lymph nodes. A total dose of 59.4 Gy (R0 resection) or 66.6 Gy (R1) was used to treat the tumor bed. Conventional fractionation was used with 1.8 Gy/d. At the time of the analysis, 36 patients were randomized or allocated to treatment arm A (with external-beam radiotherapy). Of these, 22 were treated with radiotherapy, and documentation of acute toxicity was available. Toxicity was evaluated prospectively according to the RTOG/EORTC criteria. Results: The maximal acute toxicity observed during radiotherapy was grade I in four patients, grade II in 16 patients, and grade III in two patients (9.1%; 95% confidence interval [95% CI] 1.1-29.2%). Toxicity was mainly observed at the pharynx, larynx, and skin. In 19 patients, residual toxicity within 100 days following radiotherapy was evaluated. No residual toxicity was observed in two patients. Maximal residual toxicity was grade I in 13 patients and grade II in four. No further grade III toxicity could be observed. Conclusion: The majority of patients experience mild to moderate side effects from adjuvant external-beam radiotherapy. At the first follow-up examination, most side effects have subsided. Acute

    Full Text Available HBME-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. The antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. HBME-l has also been reported to strongly and uniformly stain papillary and follicular carcinoma of the thyroid while benign disorders have been usually negative. We studied the immunoreactivity of HBME-l in 90 cases of benign and malignant thyroid lesions. We found strong positive staining in the majority of papillary carcinomas (28/31, in some of follicular carcinomas (4/6,and in a few follicular adenomas (2/17. Negative staining was found in oxyphilic cell adenoma (0/4, nodular goiter (0/13 and undifferentiated carcinoma. The results suggest that monoclonal antibody HBME-l is useful in differentiating papillary and follicular carcinoma of the thyroid from benign lesions, especially in more differentiated lesions. Strong and generalized immunoreactivity for HBME-l in a follicular lesion should raise the suspicion of malignancy, but negative staining specially in poorly differentiated lesion does not rule out malignancy.

    Background: Results from several cohort and case–control studies suggest a protective association between current alcohol intake and risk of thyroid carcinoma, but the epidemiological evidence is not completely consistent and several questions remain unanswered. Methods: The association between alcohol consumption at recruitment and over the lifetime and risk of differentiated thyroid carcinoma was examined in the European Prospective Investigation into Cancer and Nutrition. Among 477 263 eligible participants (70% women), 556 (90% women) were diagnosed with differentiated thyroid carcinoma over a mean follow-up of 11 years. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox proportional hazards models. Results: Compared with participants consuming 0.1–4.9 g of alcohol per day at recruitment, participants consuming 15 or more grams (approximately 1–1.5 drinks) had a 23% lower risk of differentiated thyroid carcinoma (HR=0.77; 95% CI=0.60–0.98). These findings did not differ greatly when analyses were conducted for lifetime alcohol consumption, although the risk estimates were attenuated and not statistically significant anymore. Similar results were observed by type of alcoholic beverage, by differentiated thyroid carcinoma histology or according to age, sex, smoking status, body mass index and diabetes. Conclusions: Our study provides some support to the hypothesis that moderate alcohol consumption may be associated with a lower risk of papillary and follicular thyroid carcinomas. PMID:26313664

    Potentially false-positive findings on radioiodine scans in children with differentiated thyroid carcinoma can mimic functioning thyroid tissue and functioning thyroid carcinomatous tissue. Such false-positive findings comprise variants and pitfalls that can vary slightly in children as compared with adults. To determine the patterns and frequency of these potential false-positive findings on radioiodine scans in children with differentiated thyroid carcinoma. We reviewed a total of 223 radioiodine scans from 53 pediatric patients (mean age 13.3 years, 37 girls) with differentiated thyroid carcinoma. Focal or regional activity that likely did not represent functioning thyroid tissue or functioning thyroid carcinomatous tissue were categorized as variants or pitfalls. The final diagnosis was confirmed by reviewing the concurrent and follow-up clinical data, correlative ultrasonography, CT scanning, serum thyroglobulin and antithyroglobulin antibody levels. We calculated the frequency of these variants and pitfalls from diagnostic and post-therapy radioiodine scans. The most common variant on the radioiodine scans was the thymic activity (24/223, 10.8%) followed by the cardiac activity (8/223, 3.6%). Salivary contamination and star artifact, caused by prominent thyroid remnant, were the most important observed pitfalls. Variants and pitfalls that mimic functioning thyroid tissue or functioning thyroid carcinomatous tissue on radioiodine scan in children with differentiated thyroid carcinoma are not infrequent, but they decrease in frequency on successive radioiodine scans. Potential false-positive findings can be minimized with proper knowledge of the common variants and pitfalls in children and correlation with clinical, laboratory and imaging data. (orig.)

    Full Text Available Poorly differentiated (insular thyroid carcinoma (PDITC is an uncommon thyroglobulin producing neoplasm intermediate in aggressiveness between well-differentiated carcinomas of follicular cell origin and undifferentiated anaplastic carcinoma. Its cytomorphological recognition is essential for planning surgery and subsequent management as it is known for its aggressive behavior, advanced stage at presentation, local recurrences and rapid dissemination. We report a case of PDITC arising in a long-standing goiter, in which presence of microfollicular structures and minimal necrosis resulted in difficulty in distinguishing it from a follicular neoplasm of thyroid.

    Full Text Available OBJECTIVES: Forkhead box P3 (FoxP3 expression has been observed in human cancer cells but has not yet been reported in thyroid cells. We investigated the prognostic significance of both FoxP3 expression and intratumoral FoxP3+ lymphocyte infiltration in differentiated thyroid carcinoma cells. METHODS: We constructed a tissue microarray with 385 thyroid tissues, including 266 malignant tissues (from 253 papillary thyroid carcinomas and 13 follicular carcinomas, 114 benign lesions, and 5 normal thyroid tissues. RESULTS: We determined the expression of FoxP3 in both tumor cells and tumor-infiltrating lymphocytes using immunohistochemical techniques. Cellular expression of FoxP3 was evident in 71% of benign and 91.9% of malignant tissues. The nuclear and cytoplasmic expression patterns were quantified separately. A multivariate logistic regression analysis indicated that cytoplasmic FoxP3 expression is an independent risk factor for thyroid malignancy. Cytoplasmic FoxP3 staining was inversely correlated with patient age. Nuclear FoxP3 staining was more intense in younger patients and in tumors presenting with metastasis at diagnosis. FoxP3+ lymphocytes were more frequent in tumors smaller than 2 cm, those without extrathyroidal invasion, and in patients with concurrent chronic lymphocytic thyroiditis. CONCLUSIONS: We demonstrated FoxP3 expression in differentiated thyroid carcinoma cells and found evidence that this expression may exert an important influence on several features of tumor aggressiveness.

The filter function of lymph nodes, which led to the idea of including lymphatic treatment in surgical management of metastases. OBJECTIVES: To evaluate morphological alterations in neck nodes in the presence of differentiated thyroid carcinoma (DTC: hyperplasia, histiocytosis, desmoplasia, capsular rupture, necrosis and their relation to the biological behavior of these neoplasias. DESIGN: Retrospective study. SETTING: University referral unit. PARTICIPANTS: 98 DTC patients, from 1977 to 1992, 18 cases were selected for histological analyses, of which 14 were female and 4 males, with an average age of 50.2 years. From these cases, 290 lymph nodes were analyzed (81 with metastasis, with an average of 16 lymph nodes/patient. MAIN MEASUREMENTS: Morphological evaluation of paraffin cuts stained by HE was done using an optical microscope, looking for presence of the abovementioned neoplasias and their UICC-TNM (1997 staging. RESULTS: Sinus histiocytosis was 2.4 times more frequent in the absence of lymph node metastasis (pNo. Disease recurrence occurred in 5 patients, all of whom were more than 40 years old (p= 0.24 and 4 of whom had necrosis (p= 0.02. Six patients with predominance of paracortical hyperplasia (p= 0.02 did not show as much relapse into disease as those with less than 6 metastasis lymph nodes (p= 0.009. CONCLUSIONS: The presence of paracortical hyperplasia is associated with a better prognosis. The existence of necrosis or metastasis in more than 6 lymph nodes in patients over 40 years of age is related to higher risk of relapse of disease in DTC.

    The rate of metastasis of high differentiated carcinoma of the thyroid glands to the neck lymph nodes was studied in people of Kemerovo Region. The metastatic lesions of pretracheal lymph nodes (VI group) were detected in 49.5% patients with papillary carcinoma and 21.0% of patients with follicular cancer. Metastases in jungular lymph nodes were revealed in 37.3% patients with papillary carcinoma. It was noted that an extension of metastatic lesions of regional lymph nodes was observed in the case of primary tumour foci spread beyond borders of the capsula glandularis in patients with papillary carcinoma. There wasn't such a relation in a case of follicular cancer. Metastases in regional lymph nodes were detected more often (67.6%) in the case of papillary carcinoma in uncontaminated zone of the thyroid gland compared with other thyroid pathology (31.7%).

    To reveal the quantitative regularities of pathological changes in the nuclei and aggregates of C and B cells and to build an expert system on their basis for the differential diagnosis of medullary and oxyphilic cell thyroid carcinoma. Puncture smears with histologically verified medullary (C cell) carcinoma and oxyphilic cell (B cell) carcinoma were investigated. The nuclei and aggregates of C cells and B cells (Hürthle cells, oncocytes) were morphometrically examined with a computer color image analyzer on the basis of a light microscope and a digital photo camera. The quantitative regularities of the degree of C and B cell aggregation in medullary and oxyphilic cell thyroid carcinoma were found by morphometry. The threshold values for the aggregates in the comparison groups and their weight coefficients formed the basis for the expert system to differentially diagnose medullary and oxyphilic cell carcinoma at the initial stages of patient examination. The clinical trials showed the high efficiency of the developed expert system.

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    Thyroid carcinoma is the commonest endocrine malignancy. The majority of these are differentiated thyroid carcinomas, which have a good overall prognosis. Treatment includes surgical excision, radio-iodine ablation and long-term thyrotropin suppression. The degree and length of suppression required, as well as the potential side-effect remain controversial. Therefore, the aim of this study was to establish the degree of thyrotropin suppression achieved in a cohort of patients with differentiated thyroid carcinoma. A retrospective review was performed of a prospectively maintained database. All patients with a diagnosis of differentiated thyroid carcinoma between January 1998 and January 2008 were identified. Demographic data, pathological stage and the treatment that the patient received was documented. TSH and free T4 levels were identified at specific time points post-operatively. Eighty-eight patients with differentiated thyroid carcinoma were identified. Seventy patients (79.5%) were female. The mean age was 55, with a range of 18 to 79 years. The majority of patients underwent a total thyroidectomy (n=79; 89.7%) and of those 29 (32.9%) had an associated modified neck dissection. Accurate follow-up was available on forty-nine patients. TSH and free T4 were measured at 3 and 6 months, as well as at 1 and 2 years post-operatively. Adequate TSH suppression was taken at a level < 0.1 mU\\/L. The majority of patients (69.5%) had achieved adequate TSH suppression at 2 years. However, 65% of these same patients had a high free T4 at 2 years indicating a degree of hyperthyroidism. This study has demonstrated that TSH suppression is being adequately achieved in the majority of patients with differentiated thyroid carcinoma. However, this must be carefully weighed against the potential detrimental side-effects of long-term sub-clinical hyperthyroidism.

    2012-02-01

    Full Text Available Abstract Background Differentiated thyroid cancer is usually associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual: only few cases were previously reported in the literature; there has been no report of axillary lymph node metastasis from follicular thyroid carcinoma. Axillary lymph node metastasis generally arises in the context of disseminated disease and carries an ominous prognosis. Case presentation Here we present a case of axillary lymph node metastasis in the context of disseminated differentiated thyroid cancer. The patient underwent near total thyroidectomy and neck and axillary lymph node dissection. A histopathological diagnosis of poorly differentiated follicular carcinoma with "signet ring cells" and Hürthle cell features was established. The patient received radioactive iodine therapy and TSH suppression therapy. Subsequently his serum thyroglobulin level decreased to 44.000 ng/ml from over 100.000 ng/ml. Discussion and Conclusion Currently there are only few reported cases of axillary node metastases from thyroid cancer, and to our knowledge, this is the first report on axillary lymph node metastasis from follicular thyroid carcinoma. "Signet ring cell" is a morphologic feature shared by both benign and, more rarely, malignant follicular thyroid neoplasm, and it generally correlates with an arrest in folliculogenesis. Our case is one of the rare "signet ring cells" carcinomas so far described.

    Five thyroid carcinomas showing clinically aggressive biologic behavior were retrospectively reviewed to evaluate the possible presence of morphologic differences from conventional thyroid carcinomas. They were originally diagnosed as follicular carcinomas, medullary carcinoma, papillary carcinoma, and mixed papillary and medullary carcinoma. There were three males and two females. The age at the time of initial diagnosis ranged from 36 years to 67 years (mean 56 years). The size of the tumor varied from 4.5cm to 10cm (mean diameter 7cm). One patient died of brain metastasis four years after the initial therapy and the other four patients are still alive with local recurrences and/or metastases to bone, spinal cord, lung, and buttock. Histologically these lesions are categorized into two different groups: insular variant and columnar cell variant. Insular variant was characterized by well-defined nests (insulae) that are composed of small, uniform cells, frequent tumor necrosis, and hyalinization of the stroma. Columnar cell variant was characterized by tall columnar cells with marked nuclear statification. All five cases stained positively for thyroglobulin and negatively for calcitonin. With the above clinical and histopathological findings, we interpreted these lesions as a poorly differentiated carcinoma, biologically in an intermediate position between well differentiated and anaplastic carcinomas. The rapid and often fatal outcome associated with these variants of poorly differentiated carcinoma warrants aggressive treatment at the time of diagnosis.

    To assess the clinical value of treatment with 131I for brain metastases from differentiated thyroid cancer (DTC), we have observed 8 cases of brain metastases from DTC who received follow-up after 131I therapy (2male, 6 female, aged 12~65 years). The results of 131I therapy were evaluated with clinical presentation, imaging scan and survival analysis. The main results are as follows. (1) All cases had been survival for 2~35 years in follow-up. (2)A space-occupying lesion in right cerebellum was reduced after taking 20.65 GBq and disappeared after 23.61 GBq,demonstrated by computed tomography. (3) The sequences and doses of 131I therapy were clearly decreased for the cases with total thyroidectomy in comparison with those with semithyroidectomy (p<0.01). (4) The brain metastases with lung and/or bone metastasis from DTC were 75% (6/8) and it was difficult to cure these metastases at the same time. It is concluded that the postoperative treatment of 131I for brain metastases from DTC after undergoing thyroidectomy may improve clinical symptoms and life quality, reduce lesions, and prolong survival.

    Cribriform-morular variant of papillary thyroid carcinoma (CMVPTC) usually occurs in the setting of familial adenomatous polyposis (FAP) although it can rarely arise sporadically. Poorly differentiated thyroid carcinoma (PDTC) is a follicular cell-derived neoplasm with more aggressive behavior than well-differentiated carcinomas such as CMVPTC. We report the case of a 35-year-old woman without FAP history who presented a left neck mass and complained of back pain. Imagiological examinations revealed a nodule in the left lobe of thyroid and multiple nodular lesions in the bone and lungs suggestive of metastases. The patient was submitted to total thyroidectomy and radioactive iodine. The tumor was composed of CMVPTC and PDTC components that shared the same somatic APC gene mutation (p.Cys520Tyr_fsX534). Besides this mutation, no CTNNB1, BRAF, N-RAS, and H-RAS gene mutations were detected in any of the 2 components. To the best of our knowledge, this is the first report of a sporadic CMVPTC with transformation into PDTC. Although the majority of CMVPTCs carry an indolent clinical outcome, the coexistence of poorly differentiated areas may justify the aggressiveness of the CMVPTC reported here.

    The indication for adjuvant postoperative radiotherapy in patients with differentiated thyroid carcinoma (DTC) extending beyond the thyroid capsule has been an issue of controversy during the past 2 decades. No randomized studies evaluating the benefit of radiotherapy have been published so far. In the Multicenter Study Differentiated Thyroid Carcinoma (MSDS), a randomization has been performed concerning external-beam radiotherapy in patients with DTC extending beyond the thyroid capsule (pT4 pN0/1/x cM0, TNM classification, 5th edition, 1997) following surgery and radioiodine therapy. Radiation-associated toxicity has been prospectively evaluated. Radiotherapy was performed with 50.4 Gy (pN0) or 54.0 Gy (pN1/x) to the cervical, supraclavicular and upper mediastinal lymph nodes. A total dose of 59.4 Gy (R0 resection) or 66.6 Gy (R1) was used to treat the tumor bed. Conventional fractionation was used with 1.8 Gy/d. At the time of the analysis, 36 patients were randomized or allocated to treatment arm A (with external-beam radiotherapy). Of these, 22 were treated with radiotherapy, and documentation of acute toxicity was available. Toxicity was evaluated prospectively according to the RTOG/EORTC criteria. The maximal acute toxicity observed during radiotherapy was grade I in four patients, grade II in 16 patients, and grade III in two patients (9.1%; 95% confidence interval [95% CI] 1.1-29.2%). Toxicity was mainly observed at the pharynx, larynx, and skin. In 19 patients, residual toxicity within 100 days following radiotherapy was evaluated. No residual toxicity was observed in two patients. Maximal residual toxicity was grade I in 13 patients and grade II in four. No further grade III toxicity could be observed. The majority of patients experience mild to moderate side effects from adjuvant external-beam radiotherapy. At the first follow-up examination, most side effects have subsided. Acute toxicity is tolerable in these patients.

  7. Contemporary post surgical management of differentiated thyroid carcinoma.

    Risk assessment is the cornerstone of contemporary management of thyroid cancer. Following thyroid surgery, an initial risk assessment of recurrence and disease-specific mortality is made using important intra-operative findings, histologic characteristics of the tumor, molecular profile of the tumor, post-operative serum thyroglobulin and any available cross-sectional imaging studies. This initial risk assessment is used to guide recommendations regarding the need for remnant ablation, external beam irradiation, systemic therapy, degree of TSH suppression, and follow-up disease detection strategy over the first 2 years after initial therapy. While this initial risk stratification provides valuable information, it is a static representation of the patient in the first few weeks post-operatively that does not change over time. Depending on how the patient responds to our initial therapies, the risk of recurrence and death may change significantly during follow-up. In order to account for differences in response to therapy in individual patients and to incorporate the impact of treatment on our initial risk estimates, we recommend a re-stratification of risk at the 2-year point of follow-up. This re-stratification provides an updated risk estimate that can be used to guide ongoing management recommendations including the frequency and intensity of follow-up, degree of ongoing TSH suppression, and need for additional therapies. Ongoing management recommendations must be tailored to realistic, evolving risk estimates that are actively updated during follow-up. By individualizing therapy on the basis of initial and ongoing risk assessments, we can maximize the beneficial effects of aggressive therapy in patients with thyroid cancer who are likely to benefit from it, while minimizing potential complications and side effects in low-risk patients destined to have a full healthy and productive life after minimal therapeutic intervention.

    The radioactive iodine has been used with great value as a diagnostic and therapeutic method in patients with differentiated thyroid carcinoma previously submitted to total thyroidectomy. False-positive whole-body scans may occur due to misinterpretation of the physiologic distribution of the radioisotope or lack of knowledge on the existence of other pathologies that could eventually present radioiodine uptake. Thymic uptake is an uncommon cause of false-positive whole-body scan, and the mechanism through which it occurs is not completely understood. The present paper reports five cases of patients with differentiated thyroid cancer who presented a mediastinum uptake of radioiodine in a whole-body scan during follow-up. The patients had either histological or radiological confirmation of the presence of residual thymus gland. It is very important to know about the possibility of iodine uptake by the thymus in order to avoid unnecessary treatment, such as surgery or radioiodine therapy. (author)

    Telomerase promoter mutations (TERT) were recently described in follicular cell-derived thyroid carcinomas (FCDTC) and seem to be more prevalent in aggressive cancers. We aimed to evaluate the frequency of TERT promoter mutations in thyroid lesions and to investigate the prognostic significance of such mutations in a large cohort of patients with differentiated thyroid carcinomas (DTCs). This was a retrospective observational study. We studied 647 tumors and tumor-like lesions. A total of 469 patients with FCDTC treated and followed in five university hospitals were included. Mean follow-up (±SD) was 7.8 ± 5.8 years. Predictive value of TERT promoter mutations for distant metastasization, disease persistence at the end of follow-up, and disease-specific mortality. TERT promoter mutations were found in 7.5% of papillary carcinomas (PTCs), 17.1% of follicular carcinomas, 29.0% of poorly differentiated carcinomas, and 33.3% of anaplastic thyroid carcinomas. Patients with TERT-mutated tumors were older (P < .001) and had larger tumors (P = .002). In DTCs, TERT promoter mutations were significantly associated with distant metastases (P < .001) and higher stage (P < .001). Patients with DTC harboring TERT promoter mutations were submitted to more radioiodine treatments (P = .009) with higher cumulative dose (P = .004) and to more treatment modalities (P = .001). At the end of follow-up, patients with TERT-mutated DTCs were more prone to have persistent disease (P = .001). TERT promoter mutations were significantly associated with disease-specific mortality [in the whole FCDTC (P < .001)] in DTCs (P < .001), PTCs (P = .001), and follicular carcinomas (P < .001). After adjusting for age at diagnosis and gender, the hazard ratio was 10.35 (95% confidence interval 2.01-53.24; P = .005) in DTC and 23.81 (95% confidence interval 1.36-415.76; P = .03) in PTCs. TERT promoter mutations are an indicator of clinically aggressive tumors, being correlated with worse outcome and

    Differentiated thyroid carcinoma is uncommon in children and constitutes 0.5% to 3% of all pediatric malignancies. Few studies have reported imaging findings of childhood papillary thyroid carcinomas. We report 3 cases of papillary thyroid carcinomas in children. Among the 3 patients, the youngest was a 7-year-old girl. In the current report, we describe 2 cases of classic papillary thyroid carcinoma and 1 case of pediatric diffuse sclerosing variant of papillary thyroid carcinoma. The ultrasonographic features and diagnostic procedures in these pediatric patients are similar to those in adults.

    The aim of this study was to assess the approaches of specialists in Spain to patients with thyroid nodules and differentiated thyroid carcinoma and to compare them with the American guideline and European consensus. We performed a cross-sectional study based on a questionnaire addressed to clinical endocrinologists specialized in thyroid cancer and specialists in nuclear medicine throughout Spain. A total of 177 questionnaires were completed, representing an overall response rate of 85%; 74% of responses were from endocrinologists and 24% from physicians active in nuclear medicine; 82% of respondents worked in third-level hospitals, 10% in second level hospitals and the remainder in private practice. Most used ultrasonography and cytology to assess thyroid nodules and collaborated with a group of surgeons expert in thyroid surgery. The majority preferred total or subtotal thyroidectomy in tumors with a diameter of 1 cm or more, and systematic lymph node dissection. Only 43 (24%) preferred prophylactic central lymph node dissection. Eighty-one respondents (45%) would still use whole body scan with ¹³¹I or ¹²³I before ¹³¹I ablation. Follow-up was based on cervical echography and thyroglobulin determination; however, 101 (57%) respondents continued to use diagnostic whole body scan in the follow-up. The approaches of the respondents were mainly in accordance with the guideline and consensus, although some variations were found, especially in the use of whole body scan with ¹³¹I before ablation and in follow-up.

    To evaluate the efficacy of radiofrequency ablation (RFA) in the treatment of loco-regional, recurrent, and well-differentiated thyroid carcinoma. Thirty-five recurrent well-differentiated thyroid carcinomas (RTC) in 32 patients were treated with RFA, between March 2008 and October 2011. RTCs were detected by regular follow-up ultrasound and confirmed by biopsy. All patients had fewer than 3 RTCs in the neck and were at high surgical risk or refused to undergo repeated surgery. Average number of RFA sessions were 1.3 (range 1-3). Post-RFA biopsy and ultrasound were performed. The mean follow-up period was 30 months. Pre- and post-RFA serum thyroglobulin values were evaluated. Thirty-one patients with 33 RTCs were treated with RFA only, whereas 1 patient with 2 RTCs was treated with RFA followed by surgery. At the last follow-up ultrasound, 31 (94%) of the 33 RTCs treated with RFA alone completely disappeared and the remaining 2 (6%) RTCs showed decreased volume. The largest diameter and volume of the 33 RTCs were markedly decreased by 93.2% (from 8.1 +/- 3.4 mm to 0.6 +/- 1.8 mm, p < 0.001) and 96.4% (from 173.9 +/- 198.7 mm{sup 3} to 6.2 +/- 27.9 mm{sup 3}, p < 0.001), respectively. Twenty of the 21 RTCs evaluated with post-RFA biopsies (95%) were negative for malignancy. One (5%) showed remaining tumor that was removed surgically. The serum thyroglobulin was decreased in 19 of 26 patients (73%). Voice change developed immediately after RFA in 6 patients (19%) and was spontaneously recovered in 5 patients (83%). Radiofrequency ablation can be effective in treating loco-regional, recurrent, and well-differentiated thyroid carcinoma in patients at high surgical risk.

    2012-01-01

    Full Text Available Background. False-positive pulmonary radioactive iodine uptake in the followup of differentiated thyroid carcinoma has been reported in patients with certain respiratory conditions. Patient Findings. We describe a case of well-differentiated papillary thyroid carcinoma treated by total thyroidectomy and radioiodine ablation therapy. Postablation radioiodine whole body scan and subsequent diagnostic radioiodine whole body scans have shown persistent uptake in the left hemithorax despite an undetectable stimulated serum thyroglobulin in the absence of interfering thyroglobulin antibodies. Contrast-enhanced chest computed tomography has confirmed that the abnormal pulmonary radioiodine uptake correlates with focal bronchiectasis. Summary. Bronchiectasis can cause abnormal chest radioactive iodine uptake in the followup of differentiated thyroid carcinoma. Conclusions. Recognition of potential false-positive chest radioactive iodine uptake, simulating pulmonary metastases, is needed to avoid unnecessary exposure to further radiation from repeated therapeutic doses of radioactive iodine.

    Full Text Available 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.

  17. Poorly differentiated forms of papillary thyroid carcinoma: distinctive entities or morphological patterns?

    The concept that poorly differentiated carcinomas (PDC) represent a group in an intermediate position in the spectrum of follicular cell-derived carcinomas of the thyroid gland is currently well established. Because at the well-differentiated end of the spectrum there are two groups of entities with distinct biological characteristics, ie, the papillary carcinoma (PC) and the follicular carcinoma (FC), we examined the group represented by PCs to ascertain whether papillary carcinoma-related PDCs (pPDC) represent merely a histologic variant or a distinct pathologic entity. For this purpose 227 consecutive PCs were reclassified according to current criteria. The association between the presence of a tumoral pattern consistent with pPDC (response variable), and prognostic factors such as gender age, pTNM (predictive variables) was evaluated in terms of odds ratio statistics. One hundred eighty-three of 227 cases, defined as PCs met the World Health Organization criteria of the not otherwise specified (NOS) (79 cases), microcarcinoma (65 cases), encapsulated (4 cases) and follicular (35 cases) variants. Forty-four cases, defined as pPDCs, met those of the tall cell (39 cases), columnar cell PC (2 cases) and mixed tall cell-columnar cell PC (3 cases) variants. Statistical analyses of the two groups of patients showed a significant correlation between differentiation and age above 40 years, extrathyroid tumor extension and low ratio of regional nodal involvement at the onset of disease. More strikingly they also showed that morphology, ie, a tumoral pattern consistent with pPDC (differentiation), is the strongest predictor of biological behavior including recurrences and recurrence-related deaths that appear to occur five and twenty times more frequently in pPDCs than in PCs, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

    The Multicenter Study Differentiated Thyroid Carcinoma (MSDS) is an ongoing study in Germany, Austria, and Switzerland on the clinical benefit of adjuvant external beam radiotherapy (RTx) for locally invasive differentiated thyroid carcinoma (DTC) in TNM stages pT4 pN0/1/x M0/x (5th ed. 1997). MSDS was designed as a prospective randomized trial. Patients receive thyroidectomy, radioiodine therapy (RIT) to ablate the thyroid remnant, and TSH-suppressive L-thyroxine therapy with or without RTx after documented elimination of cervical iodine-131 uptake (http://msds-studie.uni-muenster.de). 311 patients were enrolled between January 2000 and March 2003. 279 patients met the trial's inclusion criteria. 45 consented to randomization, of whom 17 were randomized into treatment arm A (RTx) and 18 into arm B (no RTx). Advised by the trial's independent Data Monitoring and Safety Committee, the MSDS steering committee decided to terminate randomization in April 2003 and continue MSDS as a prospective cohort study. 23 of the 234 patients in the observation arm of the trial were prescribed RTx by their physicians. Thus, 14% of the trial cohort were randomized or assigned to receive RTx (in-tention-to-treat analysis). In contrast, at least 44% of all patients with pT4 papillary DTC in Germany in the nation-wide PCES study underwent RTx in 1996 (p <0.001, chi(2)-test). Acceptance of external beam RTx as a treatment modality for DTC has receded to a degree that accrual of a sufficient number of patients for a randomized trial has been impossible. Observation of the trial cohort is continued in order to assess clinical event rates with and without RTx and chronic RTx toxicity.

Methods. A total of 126 consecutive FNACs were performed on enlarged LNs and the final diagnosis was confirmed by surgical pathology examination or clinical follow-up. The best FNAC-Tg cut-off level was selected by receiver operating curve analysis, and diagnostic performances of FNAC and FNAC-Tg were compared. Results. The rate of FNAC samples adequate for cytological examination was 77% in contrast FNAC-Tg available in 100% of aspirates (<.01. The sensitivity, specificity, and accuracy of FNAC were 71%, 80%, 74%, 100%, 80%, and 94%, respectively. The most appropriate cut-off value for the diagnosis of thyroid cancer metastatic LN was 1.1 ng/mL (sensitivity 100%, specificity 100%. Conclusions. The diagnostic performance of needle washout FNAC-Tg measurement with a cut-off of 1.1 ng/mL compared favorably with cytology in detecting DTC node metastases.

  1. A New Strategy for the Surgical Management of RLN Infiltrated by Well-Differentiated Thyroid Carcinoma

    Full Text Available Well-differentiated thyroid carcinoma (WDTC represents the most common endocrine malignancy. Despite excellent prognoses exceeding 90% in 10-year follow-up, there are clinically controversial issues. One of these is extrathyroidal tumour extension invading recurrent laryngeal nerve (RLN. The spread outside of the thyroid parenchyma and invasion to the surrounding structures, classified as always T4a, are the most important negative prognostic factor for the WDTC. Conversely, resection of the RLN leads to vocal cord paralysis with hoarseness, possible swallowing problems, and finally decreased quality of life. We propose a new algorithm for intraoperative management based on the MACIS classification, which would allow swift status evaluation pre/intraoperatively and consider a possibility to preserve the infiltrated RLN without compromising an oncological radicality. In the case of a preoperative vocal cord paralysis (VCP and confirmation of the invasive carcinoma, a resection of the RLN and the nerve graft reconstruction are indicated. Preoperatively, unaffected vocal cord movement and intraoperatively detected RLN infiltration by the invasive WDTC require an individual assessment of the oncological risk by the proposed algorithm. Preservation of the infiltrated RLN is oncologically acceptable only in specific groups of patients of a younger age with a minor size of primary tumour.

    Hashimoto's thyroiditis (HT) has been found to be associated with lymphoma, papillary carcinoma and Hürthle cell neoplasms of thyroid. In contrast, there are only a few reports of co-existence of HT with medullary carcinoma of thyroid. An overall prevalence of medullary carcinoma of only 0.35% has been reported in HT patients. Such a rare combination is being presented here. A 33 year old female presented with history of goiter for one year. Fine needle aspiration cytology (FNAC) of the swelling revealed cytological features suggestive of medullary carcinoma of thyroid. Histopathological examination of total thyroidectomy specimen revealed Hashimoto's thyroiditis along with medullary carcinoma of thyroid. Although Hashimoto's thyroiditis can uncommonly co-exist with thyroid neoplasm, its association with medullary carcinoma is extremely rare and hence being presented.

    The expression of bcl-2 and p53 was investigated by immunocytochemistry in combination with that of conventional structural and differentiation antigens on the archival material of 22 cases of undifferentiated carcinoma (UC) and 19 of poorly differentiated carcinoma (PDC) of the thyroid gland. The restriction of bcl-2 expression to PDC in comparison to UC was 84.2% versus 13.6% of cases, respectively, in contrast to an almost equal percentage of p53 expression in the two histologic types, that is, 52.6% and 54.5% of cases of PDC and UC, respectively. However, the pattern of distribution of p53-immunoreactive cells was definitely different, being restricted to areas showing active infiltrating growth in PDC and involving almost all tumor cells in UC. Furthermore, in the subset of cases of UC showing the residual presence of a differentiated component, a distinctive mutual exclusion of bcl-2 and p53 immunoreactivity was observed in the two components. The results suggest that the evaluation of bcl-2 expression may be usefully applied to the differentiation of PDC from UC, whereas all morphologic findings related to p53 expression are in keeping with a significant role of the deregulation of this gene in the mechanism of dedifferentiation and progression of the disease.

    We compared the clinical effects and prognosis of patients receiving lymph node dissection after surgical removal of the thyroid tissues and those not receiving it after the removal. A total of 80 patients diagnosed with differentiated thyroid carcinoma (DTC) by our hospital from March 2012 to March 2014 were successively included in the study. The cases were divided into the control group (n=36 cases) and observation group (n=44 cases), and the two groups underwent total or subtotal resection of the thyroid. In the control group, patients underwent preoperative high-frequency color ultrasonography, and the most suspicious lymph node was removed. In the observation group, patients underwent preoperative high-frequency color ultrasonography, and the surgeons cleared the lymph node of the widest range. Difference in clinical effects and prognosis of the two groups were compared. After nearly a year's follow-up observation, the tumor recurrence rate of the observation group was significantly lower than that of the control group and the survival rate of the observation group was significantly higher than that of the control group (P0.05). When comparing the data of lymphatic metastasis tested by preoperative high-frequency color ultrasonography with intraoperative diagnosed figures, sensitivity was 97.4%, specificity 33.3%, positive predictive value 90.2% and the negative predictive value 66.7%. In conclusion, removal of the lymph node for DTC patients having undergone thyroid tissue excision with preoperative high-frequency color ultrasonography can be beneficial to improve the effects along with reduction in the recurrence rate.

    Immunohistochemical markers (IGF-1, IGF-1R, VEGF, FGF-2, RARα and RXR) were evaluated in healthy canine thyroid glands (n=8) and in follicular-compact (n=8) and compact thyroid carcinomas (n=8). IGF-1, IGF-1R and VEGF expression was higher in fibroblasts and endothelial cells of compact carcinoma than in healthy glands (P < 0.05). Compared to follicular-compact carcinoma, compact carcinoma had higher IGF-1R expression in fibroblasts, and higher FGF-2 expression in endothelial cells (P < 0.05). RARα expression was higher in endothelial cells of compact carcinoma than in those of other groups (P < 0.05). The upregulation of these proliferation- and angiogenesis-related factors in endothelial cells and/or fibroblasts and not in follicular cells of compact carcinoma compared to healthy glands supports the relevance of stromal cells in cancer progression.

    Differentiated thyroid carcinoma of follicular origin (DTCFO), although not very frequent, has registered a raising incidence in the last decades. In the majority of the cases, DTCFO is a curable disease when treated and monitored by experienced, multidisciplinary teams. These factors contribute to an increasing number of DTCFO survivors requiring life-long monitoring, due to the possibility of occurrence of recurrences many years after the initial treatment. Several aspects of the treatment and management of these patients are still controversial. The present protocol represents the consensus of the members of the Grupo de Estudo da Tiróide of the Sociedade Portuguesa de Endocrinologia, Diabetes e Metabolismo. It aims to define guidelines, in agreement with the current state of the art and contemplating the necessary adaptations to local constrains, that ensure decreased mortality and protection of patients' quality of life, avoiding unnecessarily aggressive or ineffective treatments, optimizing the use of the available resources.

    Aim. We aim to identify protein kinases involved in the pathophysiology of papillary thyroid carcinoma (PTC) in order to provide potential therapeutic targets for kinase inhibitors and unfold possible molecular mechanisms. Materials and Methods. The gene expression profile of GSE27155 was analyzed to identify differentially expressed genes and mapped onto human protein kinases database. Correlation of kinases with PTC was addressed by systematic literature search, GO and KEGG pathway analysis. Results. The functional enrichment analysis indicated that “mitogen-activated protein kinases pathway” expression was extremely enriched, followed by “neurotrophin signaling pathway,” “focal adhesion,” and “GnRH signaling pathway.” MAPK, SRC, PDGFRa, ErbB, and EGFR were significantly regulated to correct these pathways. Kinases investigated by the literature on carcinoma were considered to be potential novel molecular therapeutic target in PTC and application of corresponding kinase inhibitors could be possible therapeutic tool. Conclusion. SRC, MAPK, and EGFR were the most important differentially expressed kinases in PTC. Combined inhibitors may have high efficacy in PTC treatment by targeting these kinases. PMID:27703281

    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), I(131) 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.

    Background Activating transcription factor 5 (ATF5) is a member of the activating transcription/cAMP response element-binding protein family of basic leucine zipper proteins that plays an important role in cell survival, differentiation, proliferation, and apoptosis. The ATF5 gene generates two transcripts: ATF5 isoform 1 and ATF5 isoform 2. A number of studies indicate that ATF5 could be an attractive target for therapeutic intervention in several tumor types; however, so far, the role of ATF5 has not been investigated in papillary thyroid carcinoma (PTC). Methods Quantitative real-time reverse transcription polymerase chain reaction and immuno-histochemical staining were used to study ATF5 mRNA and protein expression in PTC. Results We report here that ATF5 is expressed more in PTC tissue than in normal thyroid tissue. Furthermore, this is the first study that describes the presence of both ATF5 isoforms in PTC. Conclusion These findings could provide potential applications in PTC cancer treatment.

    Full Text Available Differentiated thyroid carcinoma (DTC, either papillary or follicular, has usually a very good prognosis with an overall mortality of less than 10%. In recent decades, the clinical presentation of DTC has been changing from advanced cases requiring intense treatment and surveillance to cancer detected by fortuitous neck ultrasonography requiring less aggressive treatment and follow-up. The initial treatment for DTC is total or near-total thyroidectomy whenever the diagnosis is made before surgery. Central compartment and possible lateral neck dissections should be performed when nodal metastases are present in the respective nodal basins. Post-operatively, radioactive iodine ablation with 131I followed by thyroid stimulating hormone (TSH suppression is indicated in certain patients to improve locoregional control and reduce recurrence. After initial treatment thyroidectomy and radioiodine ablation, the objectives of the follow-up of DTC is to maintain adequate thyroxine therapy and to detect persistent or recurrent disease through the combined use of neck ultrasound and basal and stimulated serum thyroglobulin (Tg with or without diagnostic whole body scan (WBS. Recent advances in the radioidine therapy and follow-up of DTC are related to the use of recombinant human TSH (rhTSH in order to stimulate Tg production and radioiodine uptake, and the ultrasensitive methods for Tg measurement during follow-up.

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

    Papillary carcinomas are the most common thyroid malignancy accounting for approximately 80 % of thyroid cancers (Rosenbaum and McHenry Expert Rev Anticancer Ther 9:317-329, 2009). They generally manifest as solitary nodules in the thyroid with or without cervical lymphadenopathy. Distant metastases though rare, are commonly seen in lungs and bones, other rare sites are parotid, skin, brain, ovary, adrenal, kidney, Pancreas and breast. We herein present an unusual case of breast lump as an initial presentation of a well differentiated thyroid cancer in a male patient. Our case is unique since it presented with isolated breast metastasis in a male patient in the absence of primary diagnosis. This prompted us to report the case with review of literature.

    Incidence of thyroid cancer is increasing in Spain and worldwide. Overall thyroid cancer survival is very high, and stratification systems to reliably identify patients with worse prognosis have been developed. However, marked differences exist between the different specialists in clinical management of low-risk patients with thyroid carcinoma. Almost half of all papillary thyroid carcinomas are microcarcinomas, and 90% are tumors < 2 cm that have a particularly good prognosis. However, they are usually treated more aggressively than needed, despite the lack of adequate scientific support. Surgery remains the gold standard treatment for these tumors. However, lobectomy may be adequate in most patients, without the need for total thyroidectomy. Similarly, prophylactic lymph node dissection of the central compartment is not required in most cases. This more conservative approach prevents postoperative complications such as hypoparathyroidism or recurrent laryngeal nerve injury. Postoperative radioiodine remnant ablation and strict suppression of serum thyrotropin, although effective for the more aggressive forms of thyroid cancer, have not been shown to be beneficial for the treatment of low risk patients, and may impair their quality of life. This guideline provides recommendations from the task force on thyroid cancer of the Spanish Society of Endocrinology and Nutrition for adequate management of patients with low-risk thyroid cancer.

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    Patients undergoing thyroidectomies at Evanston (I11) Hospital, during a six-month period had immunological studies performed preoperatively. No differential could be found between those with carcinoma or benign pathologic findings. T- and B-cell distribution and lymphocytic response to mitogens varied widely. Quantitative immunoglobulins showed slightly increased levels of IgG in patients wih carcinoma and thyroiditis in comparison with those patients with adenomas. Antithyroglobulin antibodies were negative in all patients. Pathology slides from 107 patients with thyroid carcinoma between 1972 and 1978 at Evanston Hospital were reviewed for the presence of thyroiditis, either focal or diffuse. It was found that 50% of all carcinomas had either diffuse or focal thyroiditis. Diffuse thyroiditis was more common in patients with no history of irradiation and papillary carcinoma, and in younger age groups.

    In patients with recurrent or metastatic differentiated thyroid carcinoma, residual disease despite repetitive fixed dose I-131 therapy presents an awkward situation in terms of treatment decision making. Maximal safe dose (MSD) administration base on bone marrow radiation allows the delivery of a large amount I-131 to thyroid cancer tissue within the safety margin. We investigated the efficacy of MSD in differentiated thyroid cancers, which had persisted after conventional fixed dose therapy. Forty-six patients with differentiated thyroid carcinoma who had non-responsible residual disease despite repetitive fixed dose I-131 therapy were enrolled in this study. The postoperative pathology consisted of 43 papillary carcinomas and 3 follicular carcinomas. MSD was calculated according the Memorial Sloan Kettering Cancer Center protocol using blood samples. MSDs were administered at intervals of at least 6 months. Treatment responses were evaluated using I-131 whole body scan (WBS) and serum thyroglobulin measurements. Mean calculated MSD was 12.5{+-}2.1 GBq. Of the 46 patients, 6 (13.0%) showed complete remission, 15 (32.6%) partial response, 19 (41.3%) stable disease, and 6 (13.0%) disease progression. Thus, about a half of the patients showed complete or partial remission, and of these patients, 14 (67%) showed response after a single MSD administration and 6 (29%) showed response after the second dose of MSD administrations. Twenty-nine patients (63%) experienced transient cytopenia after therapy, and recovered spontaneously with the exception of one. MSD administration is an effective method even in the patients who failed to be treated by conventional fixed dose therapy. MSD therapy of I-131 can be considered in the patients who failed by fixed dose therapy.

    Raf-1 kinase inhibitory protein (RKIP) has been implicated in several fundamental signal transduction pathways that control cellular growth, differentiation, apoptosis and migration. RKIP is reduced in a variety of human carcinomas, but RKIP expression in thyroid carcinomas has not been analyzed at the protein level. In this study, we examined the immunohistochemical expression of RKIP in various subtypes of thyroid carcinoma. Immunostaining for RKIP was performed on 104 cases of primary thyroid carcinoma (40 papillary, 29 follicular, 11 medullary, 11 poorly differentiated, and 13 anaplastic carcinomas) and 26 cases of nodal metastatic tumor (17 papillary, 4 medullary, and 5 anaplastic carcinomas). Normal thyroid tissue and all cases of follicular, papillary, and medullary carcinomas showed uniform, strong cytoplasmic immunoreactivity for RKIP. With the exception of one case, poorly differentiated carcinomas also revealed strong RKIP expression. In contrast, RKIP expression was completely absent in all anaplastic carcinomas. The transition zone from the differentiated carcinoma component (strong RKIP expression) to the anaplastic carcinoma component (no RKIP expression) demonstrated a completely opposite pattern of RKIP immunoreactivity. This reduction of RKIP expression in anaplastic carcinoma was statistically significant (P carcinomas showed uniform, strong cytoplasmic RKIP immunoreactivity, in contrast, in metastatic anaplastic carcinomas, RKIP expression was completely absent. RKIP expression is significantly reduced in anaplastic thyroid carcinoma as compared to other subtypes of thyroid carcinoma. Further studies are necessary to elucidate the precise mechanism of RKIP action in anaplastic thyroid carcinoma.

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors.

    Rosai, reinterpreting Langhans' "proliferating goiter," adopted the term "poorly differentiated carcinoma" for a specific thyroid tumor with insular features 30 years ago. This tumor type is only one of those approached by Dr. Rosai in the thyroid field (a PubMed search as of August 31, 2015 on "Rosai & thyroid" disclosed 73 articles), but seems the most innovative and representative of his heavy contribution to thyroid tumor classification. The diagnostic problems associated with PDTC recognition date back a long time, with a still ongoing debate on the nature of PDTC, its morphological diagnostic features, its clinical significance, and its optimal therapeutic approach. In 2004, PDTC was at last incorporated in the WHO classification of thyroid tumors, but the proposed diagnostic criteria were heterogeneous, controversial, and hardly applicable in the diagnostic practice. A consensus conference held in Turin in 2006 was lead by the authors and Dr. Rosai and confirmed the presence of geographical differences among claimed classical PDTC forms, which were responsible for a poor interobserver reproducibility of the diagnostic criteria. A diagnostic algorithm was therefore designed to define the crucial parameters to categorize PDTC and better stratify these distinctly aggressive tumors.

    The prognostic value of the proposed eighth edition of the American Joint Committee on Cancer (AJCC) tumor, node, and metastasis (TNM) classification is currently unclear. The aim of the study was to evaluate the prognostic value of the eighth edition of the AJCC TNM classification. We retrospectively assessed 3176 patients with differentiated thyroid carcinoma (DTC) who underwent thyroidectomy at a tertiary Korean hospital from 1996 to 2005. Cancer-specific survival (CSS) was analyzed using the Kaplan-Meier method and compared using the log-rank test. Performance of the eighth edition TNM with respect to prediction of CSS was assessed against the current seventh edition. Upon reclassification according to the eighth edition, 37.6% of patients were down-staged. The proportions of stage I and II tumors increased from 61.9% to 81.1% and from 1.7% to 16.0%, respectively, whereas those of stage III and IVB (formerly IVC in the seventh edition) decreased from 27.6% to 2.3% and 0.8% to 0.5%, respectively. The proportions of variance explained (PVEs) for the ability of the eighth and the seventh edition to predict CSS were 3.9% and 2.9%, respectively. The C-index values were 0.765 (95% confidence interval 0.764-0.766) for the eighth edition and 0.736 (0.735-0.737) for the seventh edition. Our results demonstrate that the eighth edition TNM more accurately predicts CSS for patients with DTC than does the seventh edition. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background To examine the outcomes and risk factors in pediatric differentiated thyroid carcinoma (DTC patients who were defined as TNM stage I because some patients develop disease recurrence but treatment strategy for such stage I pediatric patients is still controversial. Methods We reviewed 57 consecutive TNM stage I patients (15 years or less with DTC (46 papillary and 11 follicular who underwent initial treatment at Ito Hospital between 1962 and 2004 (7 males and 50 females; mean age: 13.1 years; mean follow-up: 17.4 years. Clinicopathological results were evaluated in all patients. Multivariate analysis was performed to reveal the risk factors for disease-free survival (DFS in these 57 patients. Results Extrathyroid extension and clinical lymphadenopathy at diagnosis were found in 7 and 12 patients, respectively. Subtotal/total thyroidectomy was performed in 23 patients, modified neck dissection in 38, and radioactive iodine therapy in 10. Pathological node metastasis was confirmed in 37 patients (64.9%. Fifteen patients (26.3% exhibited local recurrence and 3 of them also developed metachronous lung metastasis. Ten of these 15 achieved disease-free after further treatments and no patients died of disease. In multivariate analysis, male gender (p = 0.017, advanced tumor (T3, 4a stage (p = 0.029, and clinical lymphadenopathy (p = 0.006 were risk factors for DFS in stage I pediatric patients. Conclusion Male gender, tumor stage, and lymphadenopathy are risk factors for DFS in stage I pediatric DTC patients. Aggressive treatment (total thyroidectomy, node dissection, and RI therapy is considered appropriate for patients with risk factors, whereas conservative or stepwise approach may be acceptable for other patients.

    Full Text Available Background and Objective: To describe the clinical presentation, surgical intervention and treatment, complications, tumour histopathology characteristics, follow-up and survival of 23 patients at or below the age of 21 at the time of diagnosis of differentiated thyroid carcinoma (DTC diagnosis. Materials and Methods: A retrospective medical chart review of 23 patients diagnosed with DTC and treated in our institute from January 2003 to December 2013 was done. Pertinent data were collected regarding clinical presentation, workups, surgical intervention and treatment, postoperative complications, histopathology, follow-up events and survival. Results: The median age at diagnosis was 17 years. 15 patients (65.2% had papillary carcinoma and 7 patients (30.4% had papillary carcinoma with follicular variant. Multifocality and extrathyroidal extension were found in 11 (47.8% and 6 (26.1% patients respectively. 21 patients underwent total thyroidectomy with neck dissection and were subjected to thyroid ablation with radioactive iodine (radioiodine and thyroid stimulation hormone (TSH-suppressant thyroxine replacement therapy. Median follow-up was 6.6 years. Recurrence occurred in 1 patient. No significant postoperative complications were observed. Conclusion: Appropriate investigations should be carried out to exclude thyroid cancer in children and adolescents presenting with a neck mass. Total thyroidectomy with appropriate cervical lymph node dissection, followed by radioiodine ablation therapy and TSH-suppressant thyroxine replacement therapy is the recommended option to manage children and adolescents with DTC. Neck examination should be part of the routine clinical examination in the paediatric and adolescent age group. A local elaborate genetic database for this disease is essential and may help compare its behaviour with that seen in other populations.

    Thyroid cancer is the most common endocrine malignancy, representing 1% of all human malignancies; its incidence has been escalating worldwide during the last decades. In recent years important molecular pathways contributing to tumor progression and worse survival rates have been identified in iodine-refractory differentiated thyroid carcinoma (DTC) with the consequent development of molecular therapeutics to target these specific oncogenic pathways. For example, a positive correlation has been found between expression of vascular endothelial growth factor (VEGF) and a more aggressive phenotype of DTC. This has led to the widespread adoption of VEGF-targeted therapeutics in the preclinical and clinical settings. In this review we will provide an overview of the different aspects of the use of VEGF-pathway-oriented treatments in iodine-refractory DTC with particular focus on future prospects.

    2014-01-01

    Full Text Available Introduction: The differentiated thyroid cancers have a good prognosis unless the presence of metastasis. These distant metastases, especially in bone, are a major cause of impaired quality of life and death requiring intensive management. The aim of our work was to study the patients′ data, the disease characteristics and to analyze the therapeutic management of these patients. Results: This study concerned a cohort of 21 patients treated for differentiated thyroid cancer during the period from 1995 to 2011. Eighteen of our patients were aged over 45 years. A majority of them had follicular carcinoma. Bone metastases were often multiple and located at the axial skeleton. They were associated with other types of metastases, especially lung metastasis. A majority of patients received 131I treatment, following surgery or external beam radiotherapy for a palliative purpose. Overall survival was 65% at 5 years and 49% at 10 years. A long-term survival was achieved in 10% of the patients benefiting from a multidisciplinary care adapted to each case. Conclusion: Bone metastases often have a pejorative turning in the natural history of differentiated thyroid cancers. The right selection of individuals with better prognosis, for whom more aggressive curative treatment was indicated, requires a better understanding of the features of bone involvement.

    Full Text Available Papillary thyroid carcinomas (PTCs usually extend to lymph nodes in the neck and mediastinum. Rarely, they invade the neighboring upper airway anatomical structures. We report a 56-year-old woman who presented with symptoms of upper airway obstruction. Imaging studies revealed a lesion derived from the thyroid which invaded and obstructed the trachea, which appeared to be a highly differentiated PTC. Total thyroidectomy was performed, with removal of the endotracheal part of the mass along with the corresponding anterior tracheal rings. Two months later, a whole body I131 scan after recombinant human thyroid-stimulating hormone (rh-TSH administration was performed and revealed a residual mass in upper left thyroid lobe. Subsequently, 150 mCi I131 were given following rh-TSH administration. Nine months later, there was no sign of residual tumor. This case is the first one reported in the literature regarding rh-TSH administration prior to RAI ablation in a PTC obstructing the trachea.

    Distant metastasis has a negative impact on survival in differentiated thyroid carcinoma (DTC). The timing of this manifestation, however, is of unknown prognostic relevance. The aim of this retrospective study was to investigate the potential significance of discriminating synchronous versus metachronous distant metastases (SDM vs. MDM) for the outcome of patients with DTC. We retrospectively analyzed a consecutive cohort of n = 89 patients with distant metastases of DTC (43 with follicular, 46 with papillary DTC histology; mean age 52.6 ± 17.7 years) undergoing radioiodine treatment at our institution. All patients were treated with the same protocol consisting of ablative radioiodine therapy (RIT, 3.7 GBq) and one post-ablation treatment after 3 months (3.7-11.1 GBq). Further cycles of RIT were administered for recurrent, progressive or newly developed metastatic disease. We distinguished 2 types of distant metastases according to the time of manifestation: SDM (within ≤12 months after DTC diagnosis) and MDM (occurring >12 months after diagnosis). Tumor-related survival was analyzed using the Kaplan-Meier method. Uni- and multivariate analyses including the Cox proportional hazards model were performed with a significance level of p < 0.05. The mean follow-up period was 13.8 ± 1.2 years. SDM were present in 49 (55.1 %), MDM in 40 (44.9 %) patients. MDM were associated with shorter tumor-related survival (p = 0.002). 5-year and 10-year survival rates were 68.5 % and 34.8 % for MDM, and 84.3 % and 66.9 % for SDM, respectively. Within both age subgroups of <45 and ≥45 years, SDM were also linked with longer survival. No effect on tumor-related survival was found for the co-variables sex, lymph node metastases and histologic type. Distinguishing synchronous from metachronous manifestation of distant metastases may add an important prognostic feature to risk stratification in DTC, as proven metachronous appearance is associated with impaired survival.

  4. Pediatric Medullary Thyroid Carcinoma.

    Science.gov (United States)

    Starenki, Dmytro; Park, Jong-In

    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.

    Full Text Available Cribriform-morular variant of papillary thyroid carcinoma is a rare histological subtype of papillary thyroid carcinoma. This subtype is commonly reported in patients with familial adenomatous polyposis. However, cases not associated with polyposis have also been reported. The differential diagnosis of this entity from other aggressive thyroid neoplasms is important. A 29-year old man presented with a solitary mass in the left thyroid lobe underwent total thyroidectomy. Pathologic examination of the specimen revealed cribriform-morular variant of papillary thyroid carcinoma. After diagnosis, colonoscopy revealed a normal colon without polyposis. Herein, we report a case not associated with polyposis and discuss with the literature.

    The Multicentre Study Differentiated Thyroid Cancer (MSDS) collective represents a well-defined group of patients with thyroid carcinomas with extrathyroidal extension. The aim of the present study was to evaluate the relationship of the primary tumour size with clinicopathological features as well as the outcome of patients with minimum and extensive extrathyroidal growth (pT3b- and pT4a-tumours; UICC 2002/2003, 6th ed). The tumour diameter was available in 324 out of 351 MSDS patients (244 females, 80 males). Mean age of patients was 47.7±12.0 years (range, 20.1-69.8 years), and the median follow-up was 6.2 years. The relationship between primary tumour size and the following clinicopathological data was investigated: age, gender, histological tumour type (papillary thyroid carcinomas (PTC) versus follicular thyroid carcinomas (FTC)) and UICC/AJCC TNM classification. In addition, the correlation between primary tumour size and event-free and overall survival was assessed. The FTC of our series were significantly larger than PTC (3.46 vs 1.84 cm; P2 cm. Furthermore, event-free and overall survival were significantly correlated with increasing tumour size (P2 cm remained independent predictors of survival. In patients suffering from differentiated thyroid carcinoma with extrathyroidal growth (pT3b and pT4a), the tumour size is an independent predictor of event-free and overall survival.

    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

    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 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.

    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.

    Full Text Available 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.

    Thyroid carcinomas are rare and heterogeneous diseases representing less than 1% of all malignancies. The majority of thyroid carcinomas are differentiated entities (papillary and folliculary carcinomas) and are characterized by good prognosis and good response to surgery and radioiodine therapy. Nevertheless, about 10% of differentiated carcinomas recur and become resistant to all therapies. Anaplastic and medullary cancers are rare subtypes of thyroid cancer not suitable for radioiodine therapy. A small percentage of differentiated and all the anaplastic and medullary thyroid carcinomas often recur after primary treatments and are no longer suitable for other therapies. In the last years, several advances have been made in the field of molecular biology and tumorigenesis mechanisms of thyroid carcinomas. Starting from these issues, the targeted therapy may be employed as a new option. The MAP-Kinase pathway has been found often dysregulated in thyroid carcinomas and several upstream signals have been recognized as responsible for this feature. RET/PTC mutations are often discovered both in papillary and in medullary carcinomas, while B-RAF mutation is typical of papillary and anaplastic histologies. Also mTOR disruptions and VEGFR pathway disruption are common features in all advanced thyroid cancers. Some angiogenesis inhibitors and a number of RET/PTC pathway blocking agents are yet present in the clinical armamentarium. Vandetanib, cabozatinib and sorafenib have reached clinical use. A number of other biological compounds have been tested in phase II and III trials. Understanding the biology of thyroid cancers may help us to design a well shaped targeted therapy.

    Between 1969 and 1991, 113 patients with differentiated thyroid carcinoma (follicular and papillary) received radical dose megavoltage external beam radiotherapy. There were 70 females and 43 males, mean age 53 years (range 11-84). Radiotherapy was delivered to both sides of the neck and superior mediastinum, using either megavoltage photons via anterior and posterior portals, delivering a 60 Gy mid-plane dose in 30 fractions and treating daily over 6 weeks (with spinal cord shielding from the posterior field after 40 Gy), or matched 20 MeV and 35 MeV electron beams (to the neck and superior mediastinum, respectively) delivering a 75 Gy applied dose in 30 daily fractions. All patients received suppressive thyroid hormone and 74 radioiodine. Local recurrence, mostly within field, occurred in 19% of 53 patients with probable and definite residual microscopic disease (both follicular and papillary histologies). For gross residual disease (both follicular and papillary) in 49 patients, complete regression was obtained in 37.5%, partial regression in 25% and no regression in 37.5%. Median follow-up from diagnosis was 49 months (range 3-335). Overall 5-year survival rates were 85% for residual microscopic disease but only 27% for gross disease. 61 patients have died. Nineteen deaths were due to unrelated causes, 15 to distant metastases, 15 to uncontrolled local disease and 12 died with both local and distant tumours.

    Full Text Available Background/Aims: DNA HRR pathway and BER pathway play vital roles in differentiated thyroid cancer (DTC development, thus we supposed that polymorphisms of XRCC1, XRCC2, XRCC3 DNA repair genes are associated with thyroid cancer risk and progression. Methods: We searched the NCBI database for relevant literatures to determine eight SNPs to be included in our study (XRCC1: rs25487, rs25489, rs1799782; XRCC2: rs3218536; XRCC3: rs1799794, rs56377012, rs1799796, rs861539. Results: SNP of rs25487 was linked with a 53% decrease in DTC risk (OR: 0.47; 95%CI: 0.268-0.82; P = 0.01. For SNP of rs1799782, the homozygous TT genotype indicated a statistically significant 2-fold increased risk of DTC (OR: 2.09; 95%CI: 1.27-3.43; P P P = 0.02 after multivariate adjustment. Similar results for most of the SNPs were obtained from subgroup analysis by different histological types of DTC. Haplotype analysis revealed that AGC and GGT haplotypes of XRCC1 polymorphisms were associated with DTC. Moreover, results from gene-gene interaction showed that XRCC1-rs25487, XRCC1- rs1799782 and XRCC3- rs861539 variants jointly contributed to a specifically increased risk of DTC, with the combination variant of rs1799782-CT heterozygote and rs861539-TT homozygote exhibiting a higher 3.66-fold risk of DTC (OR: 3.66; 95% CI: 1.476-9.091, P = 0.005. Conclusion: Polymorphisms of XRCC1 (rs25487, rs1799782 and XRCC3 (rs861539, may play a critical role in DTC development and progression. Furthermore, XRCC1 variant can interact with XRCC3 variant to significantly increase DTC susceptibility. Identifying these genetic risk markers could provide evidence for exploring the insight pathogenesis and develop novel therapeutic strategies for DTC.

  17. Papillary Thyroid Carcinoma: Ectopic Malignancy versus Metastatic Disease

    2017-01-01

    Full Text Available Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1–3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it. We present a case of a 33-year-old man with an incidental lateral neck mass diagnosed after a motor vehicle accident. Total thyroidectomy and lymph node resection were completed without evidence of papillary thyroid carcinoma. Malignant transformation of heterotopic thyroid tissue was the final diagnosis. The possibility of an ectopic thyroid cancer should be considered in the differential diagnosis of a pathological mass in the neck. The uniqueness of this case strives in the rarity that the thyroid gland was free of malignancy, despite ectopic tissue being positive for thyroid carcinoma. Management strategies, including performance of total thyroidectomy, neck dissection, and treatment with radioiodine, should be based on individualized risk assessment.

    Recombinant human thyroid-stimulating hormone (rhTSH)-based protocol is a promising recent development in the management of differentiated thyroid carcinoma (DTC). The objectives of this prospective study were: (1) to assess the feasibility and efficacy of the rhTSH primed {sup 131}I therapy protocol in patients with DTC with distant metastatic disease, (2) to perform lesional dosimetry in this group of patients compared to the traditional protocol, (3) to document the practical advantages (patient symptoms and hospital stay) of the rhTSH protocol compared to the traditional thyroid hormone withdrawal protocol, (4) to document and record any adverse effect of this strategy, (5) to compare the renal function parameters, and (6) to compare the serum TSH values achieved in either of the protocols in this group of patients. The study included 37 patients with metastatic DTC having lung or skeletal metastases or both. A comparison of lesional radiation absorbed dose, hospital stay, renal function tests, and symptom profile was undertaken between the traditional thyroid hormone withdrawal protocol and rhTSH-based therapy protocol. Dosimetric calculations of metastatic lesions were performed using lesion uptake and survey meter readings for calculation of effective half-life. Non-contrast-enhanced CT was used for assessment of tumor volume. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL forms. A comparison of pretreatment withdrawal thyroglobulin (TG) was done with the withdrawal TG level 3 months after treatment. The mean effective half-life of {sup 131}I in metastatic lesions was less during the rhTSH protocol (29.49 h) compared to the thyroid hormone withdrawal protocol (35.48 h), but the difference was not statistically significant (p = 0.056). The mean 24-h % uptake of the lesions during the traditional protocol (4.84 %) was slightly higher than the 24-h % uptake during the rhTSH protocol (3.56 %), but

    The purpose of this study was to evaluate and compare the sonographic findings of a conventional papillary carcinoma, follicular carcinoma and a follicular variant of a papillary carcinoma. A total of 308 nodules from 231 patients that were diagnosed with a papillary carcinoma and a follicular carcinoma by surgery after sonography were analyzed. The nodules consisted of a conventional papillary carcinoma (255, 83%), a follicular variant of a papillary carcinoma (25, 8%), and a follicualar carcinoma (28, 9%). We compared and analyzed the sonographic findings of each nodule for content, margin, echotexture, shape, calcification and halo sign. A conventional papillary carcinoma showed significant different sonographic findings than a follicular carcinoma and a follicular variant of a papillary carcinoma for an ill-defined or well-defined spiculated margin (63.1%), marked hypoechogenicity (85.9%) and microcalcification (49%). A follicular carcinoma showed a significant difference than a conventional papillary carcinoma for a well-defined smooth margin (92.9%), iso, hypo- or hyperechogenicity (89.3%), wider than tall shape (100%) and halo sign (82.1%). The follicular variant of a papillary carcinoma showed similar findings to a follicular carcinoma except for marked hypoechogenicity (44%, p = 0.006) and taller than wide shape (16%, p = 0.027). The follicular carcinoma and follicular variant of a papillary carcinoma showed similar sonographic findings, but findings of a conventional papillary carcinoma were different

    Renal radioiodine excretion is {proportional_to}50% faster during euthyroidism versus hypothyroidism. We therefore sought to assess lesion dose/GBq of administered {sup 131}I activity (LDpA) in iodine-avid metastases (IAM) of differentiated thyroid carcinoma (DTC) in athyreotic patients after recombinant human thyroid-stimulating hormone (rhTSH) versus after thyroid hormone withdrawal (THW). We retrospectively compared mean LDpA between groups of consecutive patients (N = 63) receiving {sup 124}I positron emission tomography/computed tomography ({sup 124}I PET/CT) aided by rhTSH (n = 27) or THW (n = 36); we prospectively compared LDpA after these stimulation methods within another individual. Data derived from serial PET scans and one CT scan performed 2-96 h post-{sup 124}I ingestion. A mixed model analysis of covariance (ANCOVA) calculated the treatment groups' mean LDpAs adjusting for statistically significant baseline intergroup differences: non-IAM were more prevalent, median IAM count/patient lower in cervical lymph nodes and higher in distant sites, median stimulated thyroglobulin higher, mean cumulative radioiodine activity greater and prior diagnostic scintigraphy more frequent in the rhTSH patients. Mean LDpAs were: rhTSH group (n = 71 IAM), 30.6 Gy/GBq; THW group (n = 66 IAM), 51.8 Gy/GBq. The difference in group means (rhTSH less THW), -21.2 Gy/GBq, was statistically non-significant (p = 0.1667). However, the 95% confidence interval of that difference (-51.4 to + 9 Gy/GBq) suggested a trend favouring THW. The within-patient comparison found 2.9- to 10-fold higher LDpAs under THW. We found some suggestions, but no statistically significant evidence, that rhTSH administration results in a lower radiation dose to DTC metastases than does THW. A large, well-controlled, prospective within-patient study should resolve this issue. (orig.)

    Subclinical hyperthyroidism has been reported to increase the fracture risk. However, the effect of thyroid stimulating hormone (TSH) suppressive therapy on bone geometry in the hip area of patients with differentiated thyroid carcinoma (DTC) is still unclear. The aim of this study was to investigate the effect of TSH suppression on bone geometry in the hip area of pre- and postmenopausal women with DTC. We conducted a retrospective cohort study including 99 women with DTC (25 pre- and 74 postmenopausal) who had received TSH suppressive therapy for at least 3years and 297 control subjects (75 and 222, respectively) matched for sex and age. Bone mineral density (BMD) in the spine and hip area and bone geometry at the femoral neck measured by dual energy X-ray absorptiometry (DXA) were compared between patients and controls. The association between thyroid hormone and bone parameters was investigated. All analyses of bone parameters were adjusted for age, body mass index, and serum calcium levels. In premenopausal subjects, TSH suppressive therapy was not associated with poor bone parameters. In postmenopausal subjects, patients with DTC undergoing TSH suppression showed lower cross-sectional moment of inertia (CSMI), cross-sectional area, and section modulus and thinner cortical thickness at the femoral neck than those of control subjects, whereas their femoral neck BMD was comparable with controls. Total hip BMD was lower in postmenopausal patients than in controls. CSMI and section modulus at the femoral neck were independently associated with serum free T4 levels in postmenopausal patients. The difference in femoral neck bone geometry between patients and controls was only apparent in postmenopausal DTC patients with free T4 >1.79ng/dL (23.04pmol/l), and not in those with free T4 levels ≤1.79ng/dL (23.04pmol/l). TSH suppression in postmenopausal DTC patients was associated with decreased bone strength by altering bone geometry rather than BMD in the hip area

    Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that approximately 10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5-10%). Differentiated thyroid carcinoma accounts for 90% of all thyroid malignant neoplasias. Although most patients with cancer have a favorable outcome, some individuals present an aggressive form of the disease and poor prognostic despite recent advances in diagnosis and treatment. Here, a set of clinical guidelines for the evaluation and management of patients with thyroid nodules or differentiated thyroid cancer was developed through consensus by 8 member of the Department of Thyroid, Sociedade Brasileira de Endocrinologia e Metabologia. The participants are from different reference medical centers within Brazil, to reflect different practice patterns. Each committee participant was initially assigned to write a section of the document and to submit it to the chairperson, who revised and assembled the sections into a complete draft document, which was then circulated among all committee members for further revision. All committee members further revised and refined the document. The guidelines were developed based on the expert opinion of the committee participants, as well as on previously published information.

To facilitate the calculations of the optimum therapeutic activity of {sup 131} I for individual patients, a simple and fast dose planning program was created (PlanDose). The program has been set up to evaluate thryroid remant ablation, but it can also be used for the calculation of the activity to be administered for treatment of hyperthyroidism. This protocol of calculated optimal patient-specific {sup 131} I. activities allows a better determination of the necessary ablative dose for patients with differentiated carcinoma of the thyroid, and is an example of optimizing the practice of radiation protection.

    Aim: to analyse the results of differentiated thyroid cancer treatment by surgery and adjunctive radioiodine-131. Material and methods: we analysed retrospectively, from 1978 to 1993, with median age of 41.7{+-}15.o years old (sd=1), including 86 females and with medium time follow-up of 5,3{+-}4.0 years (sd=1); they corresponded to 50 cases of papillary carcinoma (pc), 40 cases of follicular carcinoma (fc) and six cases of Hurtle cells (hc). These cases were divided in two groups: 81 cases (47 pc, 28 fc and 6 hc) treated by thyroidectomy and complemental radioiodine; 15 cases (3 pc and 12 fc) treated by thyroidectomy and radioiodine to metastases; the study groups were analysed by age: less than 50 years old (72 cases) and more than 50 years old (24 cases), survival time and associated diseases. Results: group a showed one death (1.21%) and three cases (3.65%) of metastases in progression; group b, five deaths (33.33%) and five (33.33%) of metastases in progression. In patients less than 50 years old, mortality was 4.16%and metastases in progression = 5.55%; above 50 years,old the proportion were 12.5% and 16.66% respectively. All deaths and majority of distant metastases in progression occurred within 10 years of treatment. Nodular autonomous goitre was associated in seven cases (7.29%). General mortality and metastases in progression rates were 6.25% and 8.33% respectively, with all death and the most of distant metastasis in progression being due the follicular carcinoma. Conclusions: total thyroidectomy and ablation of residual thyroid tissue with radioiodine may yield the best results and be more safe; above 50 years of age the tumor has more aggressive evolution; the highest incidence of mortality and distant progressive disease occurred with 10 years of treatment; follicular carcinoma must considered as prognostic factor of risk; the association with nodular autonomous goitre is more common than usually though considered.

    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.

    Full Text Available 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.

    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.

    Full Text Available Warthin-like papillary thyroid carcinoma is a rare variant of papillary thyroid carcinoma with favorable prognosis. The tumor is named “Warthin-like papillary thyroid carcinoma” because of bearing a striking morphological resemblance to Warthin’s tumor occurring in the salivary glands. Thyroid ultrasonography of 65 years old female patient with a history of bilateral subtotal thyroidectomy 30 years ago in another center with unknown histopathological diagnosis revealed a 20 mm isoechoic solid nodule in the left lobe and this nodule was hypoactive in thyroid scintigraphy. Grossly, a grey-tan colored, solid nodule with 1 cm diameter was seen in the left lobe. Histologically, the tumor was composed of papillary structures surrounded by marked lymphocytic stroma and oncocytic cells with papillary carcinoma’s nuclear features were lining the papillae. Hashimoto’s thyroiditis was present throughout the thyroid. Immunohistochemically, tumor cells exhibited cytokeratin 19, Thyroid transcription factor-1 (TTF-1, Galectin-3, HBME-1(Mesothelioma antibody and thyroglobulin positivity, proliferative index with Ki-67 was low. Warthin-like papillary thyroid carcinoma is a rare variant of papillary thyroid carcinoma and other oncocytic cell lesions especially Hurthle cell carcinoma should be kept in mind in the differential diagnosis of this neoplasm.

    IMPORTANCE Despite performing total thyroidectomy (TT), postoperative radioactive iodine (RAI) imaging often demonstrates the presence of residual thyroid tissue within the operative bed. OBJECTIVE To measure the extent of TT using postoperative RAI imaging and assessing serum thyroglobulin (Tg) level for patients with differentiated thyroid carcinoma (DTC). DESIGN, SETTING, AND PARTICIPANTS We evaluated 245 patients undergoing TT for clinically staged cT1-3N0M0 DTC, who underwent diagnostic postoperative RAI imaging. INTERVENTIONS Total thyroidectomy. MAIN OUTCOMES AND MEASURES On the basis of quantitative measurements, RAI uptake (RAIU) in the thyroid bed of 0.2% of administered activity was selected as the cutpoint to determine the presence or absence of thyroid remnant. RESULTS By postoperative RAI imaging, TT in 106 patients (43%) resulted in RAIU of less than 0.2%. In the remaining 139 patients (57%), there was measurable iodine-avid thyroid tissue and/or tumor in the thyroid bed (n = 117 [84%]), the neck (n = 4 [3%]), or both (n = 18 [13%]). For the entire study population, mean 24-hour RAIU was 0.62%. Stimulated serum Tg levels were obtained in 232 of 245 patients (95%). Measurable stimulated Tg level (≥1 ng/mL) (to convert to micrograms per liter, multiply by 1) was found in 26 of 102 patients (25%) without thyroid remnant and in 87of 133 patients (65%) with thyroid remnant (P < .001). CONCLUSIONS AND RELEVANCE A goal of postthyroidectomy RAIU of less than 0.2% helps maximize the likelihood of an unmeasurable postoperative Tg level, potentially simplifying follow-up evaluation and reducing the use of postoperative RAI in order to facilitate surveillance.

    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 (Pcarcinoma 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 TWIST1 mRNA. Our findings support the role of epithelial-mesenchymal transition in the development of anaplastic thyroid carcinoma.

    Thyroid carcinoma mandibular metastasis are not very frequent and the cases described in literature are few. Due to its bloodstream dissemination, most of them are a consequence of the follicular variant of thyroid carcinomas. A case is presented and a review of the clinicopathologic characteristics of the lesion is made, so the oral and maxilofacial surgeon can recognize it, make a correct differential diagnosis with other mandibular radioluciencies and in consequence, carry out an adequate treatment.

    The usefulness of the myocardial perfusion agent, Tc-99m-tetrofosmin (Myoview) in the follow-up of differentiated thyroid carcinoma was evaluated in a clinical study of 15 patients, primary treated with thyroidectomy and high-dose I-131-therapy (2960-3700 MBq). 12 with suspected recurrence and metastases and three patients without any suspicion and compared with other non-specific tracers like TI-201 and Tc-99m-sestamibi. Twelve patients with elevated thyroglobulin (Tg) levels of more than 10 ng/ml (group A), four of these had negative I-131 scans, and three patients with Tg levels less than 10 ng/ml (group B) were examined under TSH suppressive L-Thyroxine treatment. Whole body scans were taken with Tl-201 (74 MBq: 20 mn post injection), Tc-99m-sestamibi (370 MBq: 20-60 min post injection) and Tc-99m-tetrofosmin (370 MBq: 20-60 min post injection). Tumor/background ratios and optional time/activity analyses (up to 150 min post injection) were evaluated using the region of interest approach. Compared with Tl-201 (T/BG: 1.59, +/- 0.396). Tc-99m-tetrofosmin showed slightly but not significant better T/BG ratios and detection rates (T/BG: 1.76, +/- 0.345). Tc-99m-sestamibi (1.51, +/- 0.31 p = 0.05) showed significantly lower values than Tc-99m-tetrofosmin In the light of these results, scintigraphy with Tc-99m-tetrofosmin seems to be a possibly sensitive imaging modality in the follow-up of DTC with possible advantages concerning T/Bg ratio, background clearance, detection rate and dosimetry compared with Tl-201 and Tc-99m-sestamibi, especially in patients with elevated Tg level and no iodine uptake, but further investigations are needed to confirm our preliminary results.

    Iodine-131 (I-131) therapy is one of the conventional approaches in the treatment of patients with differentiated thyroid carcinoma (DTC). The radioiodine agents also accumulate in the other organs that cause pain and damage to the patients. Radioiodine therapy is associated with various gastrointestinal (GI) toxicities. In this study, GI side effects of the radioiodine therapy were investigated. GI toxicities of the radioiodine therapy were studied in 137 patients with histologically proven DTC in Jun-Nov 2014. All the patients were treated by radioiodine agents in the research institute of Shariati Hospital, Tehran, Iran. The patients were examined 48 h after prescription (before discharge) and their GI side effects were registered. Correlation of the age, gender, administered dose, administered dose per body weight as the independent factors, and GI side effects were analyzed using the Pearson correlation test with Statistical Package for the Social Sciences (SPSS) version 20. Regression coefficients and linearity of the variable were investigated by MATLAB software. Line fitting was performed using MATLAB curve-fitting toolbox. From the subjects, 38 patients had GI complaints (30.4%). Significant factors influencing GI side effects were dose per body weight and administered doses. There was no significant correlation between age and gender as the independent parameters and GI complaints. The most prevalent GI side effect was nausea that occurs in 26.4% of the patients. From the results, it could be concluded that the GI side effects could be prevented by administering a safe radioiodine dose value less than 5,550 MBq. PMID:27651737

    Summary 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.

    The aim of the study was to determine the incidence of coexistence of papillary carcinoma and Hashimoto's thyroiditis in cytologic material. Cytologic findings were collected from 10508 patients that underwent ultrasound-guided fine needle aspiration cytology (FNAC) of the thyroid. Hashimoto's thyroiditis was found in 2156 (20.5%) and papillary carcinoma in 269 (2.6%) of 10508 patients with FNAC, whereas both Hashimoto's thyroiditis and papillary carcinoma were present in 42 (0.4%) patients. Among patients with FNAC diagnosis of Hashimoto's thyroiditis, the prevalence of papillary carcinoma was 1.9%. Among patients with FNAC diagnosis of papillary carcinoma, the prevalence of Hashimoto's thyroiditis was 15.6%. There was no statistically significant association between the presence of papillary carcinoma and Hashimoto's thyroiditis in patients undergoing FNAC (p=0.0522). In conclusion, in a large series of patients, the incidence of Hashimoto's thyroiditis and papillary carcinoma coexistence in cytologic material was 0.4%. There was no statistically significant relationship between Hashimoto's thyroiditis and papillary carcinoma in cytologic material.

    Follicular thyroid carcinoma is the second most common type of thyroid cancer, and its incidence has increased dramatically in recent years. Although it typically presents as a thyroid nodule, it can spread to distant sites via hematogenous dissemination. Spinal cord compression complicating thyroid carcinoma is rare with only few cases reported in the literature. This case illustrates a minimally invasive follicular carcinoma that showed such an aggressive behavior, and thus the importance of considering metastatic thyroid carcinoma in the differential diagnosis of chronic back pain, which may possibly progress to spinal cord compression carrying severe morbidity.

But no report has been made on the RFA for primary thyroid cancer to date. We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1) the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2) robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

    2004-01-01

    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

    Background Hyalinizing trabecular tumor (HTT) is a rare thyroid neoplasm, which shares some histologic features with thyroid papillary carcinoma (TPC). Clinically, it is frequently misdiagnosed as papillary carcinoma, even for some experienced pathologists. The aim of this study was to investigate whether HTT is variant of TPC or HTT is an independent entity of thyroid neoplasm.Methods The expression of CK19, galectin-3, HBME-1 and MIB-1 was detected by immunohistochemical staining in 12 cases of hyalinizing trabecular tumor and 20 cases of thyroid papillary carcinoma.Results Two of the 12 HTT samples were positive or focally positive for CK19. Four of the 12 samples of HTT presented positive to galectin-3; 3 were stained strongly and the other one was focally positive. None of the 12 samples of HTT was positive for HBME-1. Five in 12 HTT samples were stained in nucleus for MIB-1. Almost all the 20 cases of thyroid papillary carcinoma were intensely stained for CK19, galectin-3 and HBME-1. Fifteen in 20 cases of thyroid papillary carcinoma showed nuclear staining for MIB-1.Conclusions HTT is an independent thyroid neoplasm, not a variant of TPC. This study could help in the differential diagnosis of HTT from TPC. CK19, galectin-3 and HBME-1 are adequate to identify HTT and TPC, but MIB-1 does not play an important role in discrimination between HTT and TPC.

    Thyroid carcinoma is usually indolent with good prognosis, as compared to other malignancy. Distant metastases from thyroid cancer are rare and usually manifest as multiple lesions especially in lungs, bones and lymph nodes, in advanced stages of the disease. Metastasis to the breast from thyroid carcinoma is extremely rare, with about 16 cases reported in the English literature. Herein, we reported a case of metastatic poorly differentiated thyroid carcinoma, which presented as 2 breast masses in a 72-year-old woman, 6 years after total thyroidectomy for papillary thyroid carcinoma. Although the computed tomography (CT) and ultrasonography (USG) image findings are nonspecific oval mass with circumscribed or partially indistinct margin, metastases from thyroid cancer should be included in the differential diagnosis when recurrence of thyroid carcinoma is suspected. Also, fusion images of CT and USG are helpful to the radiologists in localizing the targeted lesion and conducting accurate USG-guided biopsy.

    Full Text Available Hyponatremia is an electrolyte abnormality commonly found in clinical practice. It is important to diagnose the underlying etiology of the hyponatremia and correct it appropriately because severe hyponatremia can cause serious complications and substantially increase the risk of mortality. Although hypothyroidism is known to be a cause of hyponatremia, it is rare that hyponatremia occurs in relation to hypothyroidism induced by thyroid hormone withdrawal in patients with differentiated thyroid cancer. We report a case of a 76-year-old woman with papillary thyroid carcinoma presenting with severe hyponatremia related to hypothyroidism induced by thyroid hormone withdrawal for radio-active iodine whole-body scanning, who was treated by thyroid hormone replacement and hydration. Considering that the incidence of differentiated thyroid cancer is rapidly increasing, physicians should be aware that, although uncommon, hyponatremia can occur in patients undergoing radioiodine therapy or diagnostic testing.

  13. Papillary thyroid carcinoma: Debate at rest

    2010-01-01

    Full Text Available Introduction: Papillary thyroid cancer (PTC is the most common well-differentiated cancer of the thyroid and is one of the fastest growing group of cancers probably because of the increased use of ultrasound (HRUSG in the evaluation of the thyroid in recent years. Materials and Methods: A MEDLINE and OVID database search was performed to collect information on papillary thyroid carcinoma. Recently published consensus guidelines were also used as an additional resource. Conclusions: The controversy regarding the extent of thyroidectomy in patients of PTC is relatively settled, with total thyoidectomy being the preferred approach with nodules> 1.5 cm in size. Lymph node (LN metastases do not seem to affect the overall survival, but they do increase the recurrence rate. It is worthwhile to offer LN dissection at initial surgery if LNs are ultrasonologically diagnosed to harbor malignancy. In experts hands, the rate of recurrent laryngeal nerve injury and hypoparathyroidism is negligible in a neck dissection in initial surgery and remains negligible if carried out in a redo or completion scenario.

    2014-06-15

    The expression of glucose transporter-1 (Glut-1) gene and those of major thyroid-specific genes were examined in papillary carcinoma tissues, and the expressions of these genes were compared with cancer differentiation grades. Twenty-four human papillary carcinoma tissues were included in this study. The expressions of Glut-1- and thyroid-specific genes [sodium/iodide symporter (NIS), thyroid peroxidase, thyroglobulin, TSH receptor and pendrin] were analyzed by RT-PCR. Expression levels were expressed as ratios versus the expression of beta-actin. Pathologic differentiation of papillary carcinoma was classified into a relatively well-differentiated group (n=13) and relatively less differentiated group (n=11). Glut-1 gene expression was significantly higher in the less differentiated group (0.66±0.04) than in the well-differentiated group (0.59±0.07). The expression levels of the NIS, PD and TG genes were significantly higher in the well-differentiated group (NIS: 0.67±0.20, PD: 0.65±0.21, TG: 0.74±0.16) than in the less differentiated group (NIS: 0.36±0.05, PD: 0.49±0.08, TG: 0.60±0.11), respectively. A significant negative correlation was found between Glut-1 and NIS expression, and positive correlations were found between NIS and TG, and between NIS and PD. The NIS, PD and TG genes were highly expressed in well-differentiated thyroid carcinomas, whereas the Glut-1 gene was highly expressed in less differentiated thyroid carcinomas. These findings provide a molecular rationale for the management of papillary carcinoma, especially in the selection of FDG PET or radioiodine whole-body scan and I-131-based therapy.

    2008-01-01

    BACKGROUND: The expression of vascular endothelial growth factor (VEGF) is characteristic of differentiated thyroid cancer and is associated with aggressive tumor behavior and a poor clinical outcome. Motesanib diphosphate (AMG 706) is a novel oral inhibitor of VEGF receptors, platelet......-derived growth-factor receptor, and KIT. METHODS: In an open-label, single-group, phase 2 study, we treated 93 patients who had progressive, locally advanced or metastatic, radioiodine-resistant differentiated thyroid cancer with 125 mg of motesanib diphosphate, administered orally once daily. The primary end...... point was an objective response as assessed by an independent radiographic review. Additional end points included the duration of the response, progression-free survival, safety, and changes in serum thyroglobulin concentration. RESULTS: Of the 93 patients, 57 (61%) had papillary thyroid carcinoma...

    We reclassified 720 nonmedullary invasive thyroid carcinomas diagnosed and treated between 1975 and 1993. Twenty-seven cases met the criteria of insular carcinoma and 29 cases those of widely invasive follicular carcinoma. Comparison of these histotypes with respect to pathologic stage and overall, relative, and visceral metastasis-free survival showed a significant association between histotype and pT and pN categories. In particular, pT4 (p AAA transversion at codon 61 of the N-RAS gene in insular carcinoma. These findings suggest that insular carcinoma represents a de novo entity distinct from widely invasive follicular carcinoma, that widely invasive follicular carcinoma has biologic characteristics more consistent with poorly differentiated than well-differentiated carcinomas, and that both insular carcinoma and widely invasive follicular carcinoma share similar molecular alterations.

    Full Text Available BackgroundThere 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.MethodsWe 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.ResultsSignificant 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.ConclusionFemale 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.

    The aim of this study was to compare integrated PET/CT and PET/MRI for their usefulness in detecting and categorizing cervical iodine-positive lesions in patients with differentiated thyroid cancer using {sup 124}I as tracer. The study group comprised 65 patients at high risk of iodine-positive metastasis who underwent PET/CT (low-dose CT scan, PET acquisition time 2 min; PET/CT{sub 2}) followed by PET/MRI of the neck 24 h after {sup 124}I administration. PET images from both modalities were analysed for the numbers of tracer-positive lesions. Two different acquisition times were used for the comparisons, one matching the PET/CT{sub 2} acquisition time (2 min, PET/MRI{sub 2}) and the other covering the whole MRI scan time (30 min, PET/MRI{sub 30}). Iodine-positive lesions were categorized as metastasis, thyroid remnant or inconclusive according to their location on the PET/CT images. Morphological information provided by MRI was considered for evaluation of lesions on PET/MRI and for volume information. PET/MRI{sub 2} detected significantly more iodine-positive metastases and thyroid remnants than PET/CT{sub 2} (72 vs. 60, p = 0.002, and 100 vs. 80, p = 0.001, respectively), but the numbers of patients with at least one tumour lesion identified were not significantly different (21/65 vs. 17/65 patients). PET/MRI{sub 30} tended to detect more PET-positive metastases than PET/MRI{sub 2} (88 vs. 72), but the difference was not significant (p = 0.07). Of 21 lesions classified as inconclusive on PET/CT, 5 were assigned to metastasis or thyroid remnant when evaluated by PET/MRI. Volume information was available in 34 % of iodine-positive metastases and 2 % of thyroid remnants on PET/MRI. PET/MRI of the neck was found to be superior to PET/CT in detecting iodine-positive lesions. This was attributed to the higher sensitivity of the PET component, Although helpful in some cases, we found no substantial advantage of PET/MRI over PET/CT in categorizing iodine

    Full Text Available Medullary thyroid carcinoma accounts for 4% of thyroid carcinoma and originates from parafollicular cells, secreting calcitonin and carcinoembryonic antigen (CEA. Conventional radiographic modalities such as Computerized Tomography (CT, Magnetic Resonance Imaging (MRI, and Ultrasonography (U/S, are used for detecting recurrences following total thyroidectomy. However, metastatic disease frequently escapes detection by the above modalities, even when its presence is suggested by persistently elevated serum calcitonin levels. In this paper, we report a case of medullary thyroid carcinoma in a 40 year-old woman who had whole body octreotide scintigraphy to evaluate and detect the origin of calcitonin and CEA secretion.

    Full Text Available Background Differentiated thyroid cancers (DTC are abnormal tissues growing around the thyroid gland manifesting in various forms, they vary according to geographic locations and life style. Knowledge of different types of DTC is important in order to implement cost effective treatment strategies. Aims This study was aimed at establishing the types of thyroid cancers among DTC patients managed with radioiodine post-surgery in the Department of Nuclear Medicine at Dr George Mukhari Academic Hospital (DGMAH in South Africa. Methods A retrospective five year (2007–2013 review of patient files managed post-surgery in the Nuclear Medicine Department for various thyroid diseases. A total of 51 patient files were examined. Males and females who received at least a single treatment dose of radioiodine (I-131 qualified for the study thus excluding 26 patients treated for grave’s disease and 9 DTC patients who did not receive a dose of radioiodine. A pie chart was used for categorical variables of the subtypes of carcinomas. Results The follicular carcinoma was the leading malignancy: 8 /16; (50 per cent; followed by the papillary carcinomas amounting to 6/16; (37.5; only one patient was managed for the Hurtle cell carcinoma; 1/16 (6.25 per cent and also one patient for poorly differentiated follicular carcinoma, 1/16; (6.25 per cent. Conclusion Follicular carcinoma was found to be the most common type of DTC managed at DGMAH followed by papillary carcinoma. However, the Hurtle cell carcinoma and the poorly differentiated follicular carcinomas were found to be rare.

    Aim: The usefulness of the myocardial perfusion agent, Tc-99m-tetrofosmin (Myoview{sup R}) in the follow-up of differentiated thyroid carcinoma was evaluated in a clinical study of 15 patients, primary treated with thyroidectomy and high-dose I-131-therapy (2960-3700 MBq), 12 with suspected recurrence and metastases and three patients without any suspicion and compared with other non-specific tracers like Tl-201 and Tc-99m-sestamibi. Method: Twelve patients with elevated thyroglobulin (Tg) levels of more than 10 ng/ml (group A), four of these had negative I-131 scans, and three patients with Tg levels less than 10 ng/ml (group B) were examined under TSH suppressive L-Thyroxine treatment. Whole body scans were taken with Tl-201 (74 MBq; 20 min post injection), Tc-99m-sestamibi (370 MBq; 20-60 min post injection) and Tc-99m-tetrofosmin (370 MBq; 20-60 min post injection). Tumor/background ratios and optional time/activity analyses (up to 150 min post injection) were evaluated using the region of interest approach. Results: Compared with Tl-201 (T/BG: 1.59{+-}0.396), Tc-99m-tetrofosmin showed slightly but not significant better T/BG ratios and detection rates (T/BG: 1.76, {+-}0.345). Tc-99m-sestamibi (1.51, {+-}0.31 p=0.05) showed significantly lower values than Tc-99m-tetrofosmin. Conclusion: In the light of these results, scintigraphy with Tc-99m-tetrofosmin seems to be a possibly sensitive imaging modality in the follow-up of DTC with possible advantages concerning T/Bg ratio, background clearance, detection rate and dosimetry compared with Tl-201 and Tc-99m-sestamibi, especially in patients with elevated Tg level and no iodine uptake, but further investigations are needed to confirm our preliminary results.

    After severe reactor emergencies with release of radioactive iodine, elevated thyroid cancer risk in children and adolescents is considered the main health consequence for the population exposed. We studied thyroid cancer outcome after 11.3 years' median follow-up in a selected, very high-risk cohort, 234 Chernobyl-exposed Belarusian children and adolescents undergoing postsurgical radioiodine therapy (RIT) in Germany. Cumulatively 100 children with or (without; n = 134) distant metastasis received a median 4 (2) RITs and 16.9 (6.6) GBq, corresponding to 368 (141) MBq/kg iodine-131. Outcomes were response to therapy and disease status, mortality, and treatment toxicity. Of 229 patients evaluable for outcome, 147 (64.2%) attained complete remission [negative iodine-131 whole-body scan and TSH-stimulated serum thyroglobulin (Tg) 10 μg/L, decrease from baseline in radioiodine uptake intensity in ≥ 1 focus, in tumor volume or in Tg). Except for 2 recurrences (0.9%) after partial remission, no recurrences, progression, or disease-specific mortality were noted. One patient died of lung fibrosis 17.5 years after therapy, 2 of apparently thyroid cancer-unrelated causes. The only RIT side effect observed was pulmonary fibrosis in 5 of 69 patients (7.2%) with disseminated lung metastases undergoing intensive pulmonary surveillance. Experience of a large, very high-risk pediatric cohort with radiation-induced differentiated thyroid carcinoma suggests that even when such disease is advanced and initially suboptimally treated, response to subsequent RIT and final outcomes are mostly favorable.

    A 73-year-old man presented with a chief complaint of progressive left knee pain for two months. He had a history of total thyroidectomy and central lymph node dissection due to papillary thyroid carcinoma three months ago. MRI images revealed a solid mass in the left patella. A solid mass demonstrated low signal on T1 weighed image, and high signal on T2 weighed image. And whole body bone scan showed focal photon defect in same lesion of left patella. The histologic result of left knee lesion was adenocarcinoma, consistent with metastatic papillary thyroid carcinoma. Although patellar metastasis of papillary thyroid carcinoma is very rare, when knee pain and radiologic abnormality are noted, differential diagnosis of metastasis is necessary.

    Metastatic and recurrent differentiated thyroid carcinoma is preferably treated with (131)I, 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 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.

    Gene expression profiling (GEP) of normal thyroid tissue from 43 patients with thyroid carcinoma, 6 with thyroid adenoma, 42 with multinodular goiter, and 6 with Graves-Basedow disease was carried out with the aim of achieving a better understanding of the genetic mechanisms underlying the role of normal cells surrounding the tumor in the thyroid cancer progression. Unsupervised and supervised analyses were performed to compare samples from neoplastic and non-neoplastic diseases. GEP and subsequent RT-PCR analysis identified 28 differentially expressed genes. Functional assessment revealed that they are involved in tumorigenesis and cancer progression. The distinct GEP is likely to reflect the onset and/or progression of thyroid cancer, its molecular classification, and the identification of new potential prognostic factors, thus allowing to pinpoint selective gene targets with the aim of realizing more precise preoperative diagnostic procedures and novel therapeutic approaches.This study is focused on the gene expression profiling analysis followed by RT-PCR of normal thyroid tissues from patients with neoplastic and non-neoplastic thyroid diseases. Twenty-eight genes were found to be differentially expressed in normal cells surrounding the tumor in the thyroid cancer. The genes dysregulated in normal tissue samples from patients with thyroid tumors may represent new molecular markers, useful for their diagnostic, prognostic and possibly therapeutic implications.

    Full Text Available Paucicellular variant is a rare variant of anaplastic carcinoma. Anaplastic thyroid carcinomas usually creates no problems in histologic diagnosis because of the obvious invasive growth, high cellularity, and marked degree of anaplasia, but paucicellular variant of anaplastic carcinoma is problematic in diagnosis because of its histologic mimicry to benign lesions, e.g. Riedel disease and fibrous variant of Hashimoto thyroiditis, i.e. prominent fibrosis and low cellularity. It is important to distinguish it from these two lesions because both are reactive conditions with favorable prognosis while anaplastic carcinoma is a malignant condition with poor prognosis. We present a case of 45-year-old female presented with a history of thyroid swelling for 10 years. The cytological diagnosis was given as colloid goiter while histopathological examination turned out to be paucicellular variant of anaplastic carcinoma thyroid. To conclude paucicellular variant is the entity to which all pathologists should be familiar and should know differential diagnosis while dealing with any fibrosed lesion of the thyroid.

    Follicular thyroid carcinoma is the second most common type of thyroid cancer, and its incidence has increased dramatically in recent years. Although it typically presents as a thyroid nodule, it can spread to distant sites via hematogenous dissemination. Bone metastasis is diagnosed clinically in 2%-13% of patients with differentiated thyroid cancer; nevertheless spinal cord compression complicating thyroid carcinoma is rare and only few cases has been reported in the literature. This case illustrates a strange case of a minimally invasive follicular carcinoma that showed an aggressive behavior, and thus the importance of considering metastatic thyroid carcinoma in the differential diagnosis of chronic back pain progressing to spinal cord compression carrying a severe morbidity.

    The incidence of papillary thyroid cancer (PTC) is markedly higher in women than men during the reproductive years. In vitro studies have suggested that estrogen may play an important role in the development and progression of PTC through estrogen receptors (ERs). This study aimed to investigate the expression patterns of the two main ER subtypes, α and β1 (wild-type ERβ), in PTC tissue and their clinical significance. Immunohistochemical staining of thyroid tissue sections was performed to detect ER expression in female patients with PTC (n =89) and nodular thyroid goiter (NTG; n =30) using the Elivision™ plus two-step system. The relationships between ER subtype expression and clinicopathological/biological factors were further analyzed. The positive percentage and expression levels of ERα were significantly higher in female PTC patients of reproductive age (18-45 years old; n =50) than age-matched female NTG patients (n =30), while ERβ1 exhibited the opposite pattern. There was no difference in ERα or ERβ1 expression between female PTC patients of reproductive age and those of advanced reproductive age (>45 years old; n =39). In the female PTC patients of reproductive age, ERα expression level was positively correlated with that of Ki-67, while ERβ1 was negatively correlated with mutant P53. Furthermore, more patients with exclusively nuclear ERα expression had extrathyroidal extension (ETE) as compared with those with extranuclear ERα localization. VEGF expression was significantly decreased in female PTC patients of reproductive age with only nuclear ERβ1 expression when compared with those with extranuclear ERβ1 localization. In PTC patients of advanced reproductive age, neither ERα nor ERβ1 expression showed any correlation with that of Ki-67, mutant P53, VEGF, tumor size, TNM stage, ETE, or lymph node metastases. The differential expression patterns of the two ER subtypes between PTC and NTG indicate that ERα may be a useful

    OBJECTIVE To investigate the protein expression of HBME-1, CD15 and p53 in thyroid carcinoma and in bengin thyroid diseases and to evaluate their value in diagnosis of thyroid disease. METHODS Sixty-one cases of thyroid carcinoma and 27 cases of different kinds of benign thyroid diseases were studied by immunohistochemical methods.RFSUTLS All cases of differentiated thyroid carcinoma were positive for HBME- 1,35.7% positive for CD15 and only 14.3% positive for p53. Twentyseven cases of benign thyroid lesions were absolutely negative for p53,7.4% of which were CD15 positive and 25.9% of which were HBME-1 positive. CONCLUSION HBME-1 and CD15 may be helpful to assist differential diagnosis of thyroid carcinoma from benign thyroid diseases.

    Full Text Available Background. Simultaneous presence of Hashimoto's thyroiditis and papillary thyroidal carcinoma in thyroidal gland with papillary carcinoma association in thyroglossal duct is quite rare. The questions like where the original site of primary process, is where metastasis is, what the cause of coexisting of these diseasesis present a diagnostic dilemma. Case report. We presented a case of a 53-year old female patient, with the diagnosis of Hashimoto's thyroiditis and symptoms of subclinical hypothyreosis and nodal changes in the right lobe of thyroidal gland, according to clinical investigation. Morphological examination of thyroidal gland, ultrasound examination and scintigraphy with technetium (Tc confirmed the existence of nonhomogenic tissue with parenchyma nodular changes in the right lobe of thyroidal gland that weakly bonded Tc. Fine needle biopsy in nodal changes, with cytological analyses showed no evidence of atypical thyreocites. Hashimoto's thyroiditis was confirmed on the basis of the increased values of anti-microsomal antibodies, the high levels of thyreogobulin 117 ng/ml and TSH 6.29 μIU/ml. The operation near by the nodular change in the right lobe of thyroidal gland revealed pyramidal lobe spread in the thyroglossal duct. Total thyroidectomia was done with the elimination of thyroglossal duct. Final patohystological findings showed papillary carcinoma in the nodal changes pT2, N0 and in the thyroglossal duct with the presence of Hashimoto's thyroiditis in the residual parenchyme of the thyroid gland. After the surgery the whole body scintigraphy with iodine 131 (131I did not reveal accumulation of 131I in the body, while the fixation in the neck was 1%. After that, the patient was treated with thyroxin with suppressionsubstitution doses. Conclusion. Abnormality in embrional development of thyroidal tissue might be the source of thyroidal carcinoma or the way of spreading of metastasis of primary thyroidal carcinoma from thyroid

    Radioiodine therapy has attained a significant role in the treatment of differentiated thyroid cancer. The literature addressing possible secondary effects of {sup 131} I is limited, although there has been increasingly interest in this field. A more comprehensive understanding of the mutagenic effects of radiation on the offspring of women exposed to {sup 131} I is mandatory in view of the possibility of occurrence of miscarriages, congenital abnormalities and malignancies in these children. In this review, we found that many reports on safety of this type of treatment in female patients in reproductive age recommend that pregnancy should be avoided for at least one year after therapeutic administration of radioiodine.

    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 {sup 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 {sup 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 {sup 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.

    Full Text Available Anaplastic thyroid carcinoma is one of the most aggressive of all human malignant diseases. It has an unfavorable prognosis and responsible for most of the mortality and morbidity rates due to thyroid carcinomas. We present a case of incidental anaplastic thyroid carcinoma and discuss the epidemiology, biology, risk factors, prognostic factors of the disease and the approach to treatment, in the light of the current medical literature. The prognosis is much better in cases with incidental carcinoma compared to the classical type and surgical excision of the tumor has a favorable effect on the results. Our case was followed-up for 1.5 years with no evidence of recurrence or metastasis.

    As {sup 131}I therapy, used to achieve ablation of thyroid gland remnant, can cause chromosome damage in cultured peripheral lymphocytes especially, we investigated whether administration of radioiodine may induce early genome damage in peripheral T lymphocytes of adolescents with differentiated thyroid carcinoma (DTC). We studied 11 patients, aged 14.8 {+-} 3.1 years, who assumed {sup 131}I (range: 1.11-4.44 GBq) to ablate thyroid remnant. A blood sample for micronucleus assay and for evaluating expression of some genes involved in the DNA repair or the apoptosis pathways was obtained from each patient 1 h before (T{sub 0}) and 24 (T{sub 1}) and 48 h (T{sub 2}) post-radioiodine administration. Compared to T{sub 0}, we did not find any difference in the number of micronucleated cells at both T{sub 1} and T{sub 2} in any subject. Nine out of 11 patients had altered expression levels in a majority of the DNA repair and apoptosis genes at T{sub 1}, which decreased at T{sub 2}. We demonstrated for the first time that peripheral cells of DTC children and adolescents who received {sup 131}I at a mean dosage of 3.50 {+-} 0.37 GBq did not show chromosome damage within 48 h from the end of radiometabolic therapy. This may be due to a prompt activation of the cell machinery that maintains the integrity of the genome to prevent harmful double-strand breaks from progressing to chromosome mutations, either by repairing the lesions or by eliminating the most seriously damaged cells via apoptosis.

    Thyroid carcinoma is an extracolonic manifestation that is present in about 1% to 2% of patients with familial adenomatous polyposis (FAP). Less than 100 cases have been reported in detail. We have investigated the suggestion that FAP associated thyroid carcinoma is significantly different morphologically from both papillary and follicular types and can be considered as a separate entity. Specimens from three patients with FAP associated thyroid tumours, all but one having single nodules, have been analysed. All three patients belonged to an extended kindred (23 siblings in four generations) who had genetic analysis and intensive screening for thyroid nodules. Seven patients had the same APC mutation at codon 1061. Pathological examination revealed a typical papillary carcinoma, encapsulated variant, in all patients, with follicular areas in one case. All thyroid specimens, in addition to histological and immunohistological examinations, were also specifically studied for activation of the RET-PTC oncogene, that seems to be restricted to papillary thyroid carcinoma. Two of the three patients had RET-PTC activation (PTC1 isoform). The findings suggest that the tumours were certainly papillary, at least in the present kindred. Further studies in different families are required for a better understanding of this peculiar tumour and of its biological behaviour.

  2. Synchronous Parathyroid and Papillary Thyroid Carcinoma

    Full Text Available Concomitant thyroid disease is not unusual among patients with primary hyperparathyroidism. However, the simultaneous occurrence of parathyroid and thyroid carcinoma is extremely rare. We report a 38-year-old man with primary hyperparathyroidism who presented with osteitis fibrosa cystica complicated with pathologic femoral neck fracture. Preoperative investigation for exclusion of multiple endocrine neoplasia did not find evidence of medullary thyroid carcinoma or pheochromocytoma, but imaging studies revealed the presence of nodules in the right lobe and a parathyroid lesion over the left inferior pole of the thyroid gland. Total thyroidectomy, left parathyroidectomy, and bipolar hemiarthroplasty of the left hip were then performed simultaneously. The resected specimens were pathologically identified as papillary thyroid carcinoma and parathyroid carcinoma, respectively. After the operation, 131I ablation therapy was administered at a dose of 120 mCi. Additional doses of 30 mCi were given yearly as serum thyroglobulin level became elevated. Serum calcium level remained normal during yearly follow-up. Although parathyroid carcinoma is an uncommon cause of parathyroid hormone-dependent hypercalcemia, it should nonetheless be given due consideration because its surgical approach differs from that of parathyroid adenoma. As the coexistence of parathyroid and non-medullary thyroid carcinoma has previously been reported, the possibility of both malignancies must also be considered in the setting of primary hyperparathyroidism with thyroid nodules. If confirmed with preoperative parathyroid scintigraphic and other laboratory studies, an optimal outcome may be achieved with complete resection of both tumors at the time of initial operation, followed by adjunctive therapy.

    The RAS-RAF-MEK-ERK-MAP kinase pathway mediates the cellular response to extracellular signals that regulate cell proliferation, differentiation, and apoptosis. Mutation of the RAS proto-oncogene occurs in various thyroid neoplasms such as papillary thyroid carcinomas (PTCs), follicular thyroid adenomas and carcinomas. A second genetic alteration frequently involved in PTC is RET/PTC rearrangements. Recent studies have shown that BRAF, which is a downstream signaling molecule of RET and RAS, is frequently mutated in melanomas. This study tests whether BRAF is also mutated in thyroid tumors and cell lines. We analyzed BRAF gene mutation at codon 599 in thyroid tumors using mutant-allele-specific PCR and in 10 thyroid tumor cell lines by DNA sequencing of the PCR-amplified exon 15. We found that BRAF was mutated in 8 of 10 thyroid tumor cell lines, including 2 of 2 papillary carcinoma cell lines, 4 of 5 anaplastic carcinoma cell lines, 1 of 2 follicular carcinoma cell lines, and 1 follicular adenoma cell line. BRAF mutation at codon 599 was detected in 21 of 56 PTC (38%) but not in 18 follicular adenomas and 6 goiters. BRAF mutation occurred in PTC at a significantly higher frequency in male patients than in female patients. To test whether BRAF mutation may cooperate with RET/PTC rearrangements in the oncogenesis of PTC, we tested whether BRAF-mutated PTCs were also positive for RET/PTC rearrangements. Immunohistochemical staining was conducted to evaluate RET/PTC rearrangements by using two different anti-RET antibodies. Surprisingly, we found that a large number of BRAF-mutated PTCs (8 of 21) also expressed RET, indicating that the RET proto-oncogene is rearranged in these BRAF-mutated PTCs. These observations suggest that mutated BRAF gene may cooperate with RET/PTC to induce the oncogenesis of PTC.

    2005-02-01

    Interleukin-1beta (IL-1beta) is a pleiotropic cytokine that can induce several cellular signal transduction pathways. Here, we show that IL-1beta can induce cell cycle arrest and differentiation in the human medullary thyroid carcinoma (MTC) cell line, TT. IL-1beta induces cell cycle arrest accompanied by morphological changes and expression of the neuroendocrine marker calcitonin. These changes are blocked by the MEK1/2 specific inhibitor U0126, indicating that MEK1/2 is essential for IL-1beta signaling in TT cells. IL-1beta induces expression of leukemia inhibitory factor (LIF) and activation of STAT3 via the MEK/ERK pathway. This activation of STAT3 could be abrogated by treatment with anti-LIF neutralizing antibody or anti-gp130 blocking antibody, indicating that induction of LIF expression is sufficient and essential for STAT3 activation by IL-1beta. In addition to activation of the LIF/JAK/STAT pathway, IL-1beta also induced an MEK/ERK-mediated intracellular cell-autonomous signaling pathway that is independently sufficient for growth arrest and differentiation. Thus, IL-1beta activates the MEK/ERK pathway to induce growth arrest and differentiation in MTC cells via dual independent signaling mechanisms, the cell-extrinsic LIF/JAK/STAT pathway, and the cell-intrinsic autonomous signaling pathway.

    The therapeutic approach to thyroid carcinoma usually involves surgery as initial treatment. The use of external beam radiotherapy (EBRT) is limited to high-risk patients and depends on clinical stage and histologic type. Different behavior patterns and degrees of aggressiveness of thyroid carcinomas require different management for differentiated, medullary, and anaplastic carcinoma. However, the role of EBRT is an issue of debate. Most clinical studies are retrospective and based on single-institution experiences. In this article, we review the main literature and give recommendations for the use of EBRT in thyroid carcinoma on behalf of the "Radioterapia Metabolica" Group of the Italian Radiation Oncology Association.

    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

    Full Text Available 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 (. 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.

    Full Text Available Background/Aim. The most sensitive indicators for detecting recurrence of well-differentiated thyroid cancer (DTC are 131I whole body scintigraphy (WBS and measurement of serum thyroglobulin (Tg. In order to perform it, it is necessary to raise the level of endogenous tiroidstimulating hormon (TSH, which can be achieved by Lthyroxine withdrawal for 3-5 weeks or administration of recombinant human thyrotropin (rhTSH without requiring the discontinuation of thyroid hormone therapy. The aim of this study was to assess the effect of rhTSH using in comparison to the traditional thyroid hormone withdrawal in the follow-up of patients with DTC. Methods. This retrospective study included 44 patients, mean age 48.8 years, with DTC divided into 2 groups. The group I consisted of patients (n = 31 in which the analysis in the follow-up (WBS with 131I, TSH, Tg and antiTgAt made in the hypothyroid state, and group II patients (n = 13 in which they made after the administration of rhTSH. The presence of 13 symptoms and signs of hypothyroidism was investigated on the day of giving 131I. Quality of life was evaluated using a modified form: the quality of life scale (SF-36 completed on the day of giving 131I. Results. In both groups, serum TSH reached a very good stimulation level, but significantly higher in the group II (group I 30.3-101.5 µlU/mL, group II 68.6-192.0 µlU/mL, p < 0.05. In both groups, TSHstimulated Tg was higher (group I 0.1-546.0 ng/mL, group II 0.1-7517 ng/mL comapred to value during the Lthyroxine therapy (group I 0.1-495.0 ng/mL, group II 0.1- 2785 ng/mL. There was no difference in technical quality of WBS obtained from both groups. The patients in the group I had attended 8-13 symptoms of hypothyroidism, while patients in group II did not have symptoms of hypothyroidism. The patients after application of rhTSH, showed statistically significantly better quality of life as compared with those who showed to have L-thyroxine withdrawal, (74

    Anaplastic thyroid carcinoma is a rare disease, and cases associated with eosinophilia are even rarer. We herein report a case of anaplastic thyroid carcinoma accompanied by remarkable and uncontrollable eosinophilia. A 71-year-old man was diagnosed with end-stage anaplastic thyroid carcinoma. Throughout the aggressive clinical course of the cancer, eosinophilia dramatically progressed and became extremely refractory to steroid treatment. We measured the serum levels of hematopoietic cytokines potentially involved in eosinophilia, including granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin (IL)-3 and IL-5. Although the GM-CSF level was moderately elevated, both the IL-3 and IL-5 levels were within the normal ranges. In this case, the patient's eosinophilia may have been related to his severe dyspnea and was likely responsible for the allergic reaction to the anticancer drug. Therefore, it is essential to elucidate the etiology of eosinophilia in patients with thyroid cancer in order to improve the treatment for patients with anaplastic thyroid carcinoma.

    Mandibular metastasis of thyroid carcinoma is extremely rare. We present the case of a 46-year-old woman who had bilateral huge cheek masses that had grown rapidly over several years. Intra-oral mucosal tissue biopsy and imaging work-up including computed tomography scan and magnetic resonance imaging were performed and the initial diagnosis was presumed to be central giant cell granuloma. Incidentally detected thyroid lesions were studied with ultra-sonography guided fine needle aspiration and diagnosed as simple benign nodules. Due to continuous oral bleeding and the locally destructive feature of the lesions, we decided to excise the mass surgically. To avoid functional deficit, a stepwise approach was performed: Firstly, the larger left mass was excised and the mandible was reconstructed with a fibular free flap. The final pathologic diagnosis was follicular thyroid cancer. Postoperative I-131 thyroid scan and whole body positron-emissions-tomography were performed. Right side mass was revealed as a thyroid malignancy. Multiple bony metastases were detected. Since further radioactive iodine therapy was required, additional total thyroidectomy and right side mandibulectomy with fibular free flap reconstruction was performed. The patient also underwent high dose radioactive iodine therapy and palliative extra-beam radiotherapy for the metastatic lumbar lesion. Follicular thyroid carcinoma should be considered as a differential diagnosis for mandibular mass lesions.

    Ultrasonography (US) is routinely used to evaluate thyroid nodules. The US features of papillary thyroid carcinoma (PTC), the most common thyroid malignancy, include hypoechogenicity, spiculated/microlobulated margins, microcalcifications, and a nonparallel orientation. However, many PTC variants have been identified, some of which differ from the classic type of PTC in terms of biological behavior and clinical outcomes. This review describes the US features and clinical implications of the variants of PTC. With the introduction of active surveillance replacing immediate biopsy or surgical treatment of indolent, small PTCs, an understanding of the US characteristics of PTC variants will facilitate the individualized management of patients with PTC.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    Hürthle cell carcinoma is a rare variant of differentiated thyroid cancer that occasionally forms distant metastases. However, even in the presence of metastases, patients with Hürthle cell carcinoma have a relatively good prognosis. There are few reports of Hürthle cell carcinoma metastases to the vertebral column, and none describing aggressive resection of spinal metastases. Here, we report a 68-year-old woman with a solitary metastasis of Hürthle cell carcinoma to the T1 vertebral body causing severe kyphotic deformity, myelopathy, and pain. The patient was treated with aggressive excisional decompression of the spinal cord and T1 vertebral body resection from an entirely posterior approach. Reconstruction and stabilization of the anterior spine was accomplished with a transforaminal lumbar interbody fusion allograft spacer and posterior instrumentation. We discuss aspects of the diagnosis, management, patient selection, and surgical treatment of metastatic Hürthle cell carcinoma in reference to the literature.

    CCL2 is a chemokine known to recruit monocytes/macrophages to sites of inflammation. CCL2 is also associated with tumor progression in several cancer types. Recently, we showed that the N-terminus of CCL2 is modified to a pyroglutamate (pE)-residue by both glutaminyl cyclases (QC (QPCT)) and its isoenzyme (isoQC (QPCTL)). The pE-residue increases stability against N-terminal degradation by aminopeptidases. Here, we report an upregulation of QPCT expression in tissues of patients with thyroid carcinomas compared with goiter tissues, whereas QPCTL was not regulated. In thyroid carcinoma cell lines, QPCT gene expression correlates with the mRNA levels of its substrate CCL2. Both QPCT and CCL2 are regulated in a NF-κB-dependent pathway shown by stimulation with TNFa and IL1b as well as by inhibition with the IKK2 inhibitor and RNAi of p50. In the culture supernatant of thyroid carcinoma cells, equal amounts of pECCL2 and total CCL2 were detected by two ELISAs discriminating between total CCL2 and pECCL2, concluding that all CCL2 is secreted as pECCL2. Activation of the CCL2/CCR2 pathway by recombinant CCL2 increased tumor cell migration of FTC238 cells in scratch assays as well as thyroid carcinoma cell-derived CCL2-induced migration of monocytic THP1 cells. Suppression of CCL2 signaling by CCR2 antagonist, IKK2 inhibitor, and QPCT RNAi reduced FTC238 cell growth measured by WST8 proliferation assays. Our results reveal new evidence for a novel role of QC in thyroid carcinomas and provide an intriguing rationale for the use of QC inhibitors as a means of blocking pECCL2 formation and preventing thyroid cancer metastasis.

    Serum calcitonin is a tumor marker used in the diagnosis and follow-up of medullary thyroid carcinoma. Calcitonin washout evaluation is a new method used for suspicious thyroid nodules and lymph nodes. Limited clinical data are present about the efficacy of this method. A 61-year-old female patient with known Hashimoto's thyroditis and an 8-mm hypoechoic nodule was presented with one previously benign fine-needle aspiration cytology (FNAC). On referral to our department, she had a moderately high-serum calcitonin level, and we repeated the FNAC that was reported as nondiagnostic. We performed FNAC for the third time together with calcitonin washout evaluation from the thyroid nodule. The FNAC was again nondiagnostic, but the calcitonin washout level from the thyroid nodule was 152.569 pg/mL. Total thyroidectomy was performed, and the diagnosis was confirmed as medullary thyroid carcinoma. Calcitonin washout evaluation may be a useful method in the differential diagnosis of patients with thyroid nodules having moderately high-serum calcitonin levels.

    Full Text Available Abstract Introduction Subacute lymphocytic thyroiditis is anautoimmune thyroid disease presenting with transient thyrotoxicosis as well as transient hypothyroidism. Several factors have been thought to be the initiating event in subacute lymphocytic thyroiditis. However, subacute lymphocytic thyroiditis that develops after thyroid lobectomy has not yet been reported in the literature. We report a case of subacute lymphocytic thyroiditis after lobectomy in a patient with papillary thyroid carcinoma. Case presentation A 30-year-old Korean woman was referred to our center for thyroid tumor operation. She was diagnosed with suspicious papillary thyroid carcinoma by fine needle aspiration at a local medical clinic. The thyroid ultrasonography demonstrated a diffusely enlarged thyroid gland with a 0.4×0.3cm sized hypoechoic nodule in the left lobe. Left thyroid lobectomy by endoscopic thyroidectomy was performed via a transaxillary approach, and the nodule was confirmed to be a papillary thyroid carcinoma. On postoperative day 1, a thyroid function test revealed hyperthyroidism, and on postoperative day 8, a thyroid function test again revealed hyperthyroidism with decreased radioactive iodine uptake. Thyroid function tests showed euthyroid on postoperative day 48 and hypothyroidism on postoperative day 86. She was treated with levothyroxine. Conclusion Subacute lymphocytic thyroiditis can develop after thyroid lobectomy. Thyroid autoantigen released during thyroid lobectomy may cause the onset or exacerbation of the destructive process.

    Complaints of a dry mouth (xerostomia) and sialoadenitis are frequent side effects of radioiodine treatment in differentiated thyroid cancer (DTC) patients. However, detailed prospective data on alterations in salivary gland functioning after radioiodine treatment ((131)I) are scarce. Therefore, the primary aim of this study was to prospectively assess the effect of high-activity radioiodine treatment on stimulated whole saliva flow rate. Secondary aims were to study unstimulated whole and stimulated glandular (i.e., parotid and submandibular) saliva flow rate and composition alterations, development of xerostomia, characteristics of patients at risk for salivary gland dysfunction, and whether radioiodine uptake in salivary glands on diagnostic scans correlates to flow rate alterations. In a multicenter prospective study, whole and glandular saliva were collected both before and 5 mo after radioiodine treatment. Furthermore, patients completed the validated xerostomia inventory. Alterations in salivary flow rate, composition, and xerostomia inventory score were analyzed. Salivary gland radioiodine uptake on diagnostic scans was correlated with saliva flow rate changes after radioiodine treatment. Sixty-seven patients (mean age ± SD, 48 ± 17 y; 63% women, 84% underwent ablation therapy) completed both study visits. Stimulated whole saliva flow rate decreased after ablation therapy (from 0.92 [interquartile range, 0.74-1.25] to 0.80 [interquartile range, 0.58-1.18] mL/min, P = 0.003), as well as unstimulated whole- and stimulated glandular flow rates (P subjective feeling of dry mouth increased (P = 0.001). Alterations in saliva flow rate were not associated with semiquantitatively assessed radioiodine uptake in salivary glands on diagnostic scans. For the small cohort of patients undergoing repeated radioiodine therapy, we could not demonstrate alterations in salivary parameters. We prospectively showed that salivary gland function is affected after high

    The incidence of thyroid cancer has increased in eastern Europe since the Chernobyl nuclear power plant accident. Although the radioactive fallout was much less severe and the thyroid radiation dose was much lower in France, a case-control study was initiated in eastern France. The present study included 633 young women who were diagnosed with differentiated thyroid cancer before 35 years of age between 2002 and 2006 and matched with 677 controls. Face-to-face interviews were conducted from 2005 to 2010. Odds ratios were calculated using conditional logistic regressions and were reported in the total group and by histopathological type of cancer ("only papillary" and "excluding microcarcinomas"). The risk of thyroid cancer was higher in women who had a higher number of pregnancies, used a lactation suppressant, or had early menarche. Conversely, breastfeeding, oral contraceptive use, and late age at first pregnancy were associated with a lower risk of thyroid cancer. No association was observed between thyroid cancer and having irregular menstrual cycle, undergoing treatment for menstrual cycle regularity shortly after menarche, having a cessation of menstruation, use of another contraceptive, history of miscarriage or abortion for the first pregnancy, or having had gestational diabetes. This study confirms the role of hormonal and reproductive factors in thyroid cancer, and our results support the fact that exposure to estrogens increases thyroid cancer risk.

    Full Text Available Homologous recombination (HR is the major pathway for repairing double strand breaks (DSBs in eukaryotes and XRCC2 is an essential component of the HR repair machinery. To evaluate the potential role of mutations in gene repair by HR in individuals susceptible to differentiated thyroid carcinoma (DTC we used high resolution melting (HRM analysis, a recently introduced method for detecting mutations, to examine the entire XRCC2 coding region in an Iranian population. HRM analysis was used to screen for mutations in three XRCC2 coding regions in 50 patients and 50 controls. There was no variation in the HRM curves obtained from the analysis of exons 1 and 2 in the case and control groups. In exon 3, an Arg188His polymorphism (rs3218536 was detected as a new melting curve group (OR: 1.46; 95%CI: 0.432-4.969; p = 0.38 compared with the normal melting curve. We also found a new Ser150Arg polymorphism in exon 3 of the control group. These findings suggest that genetic variations in the XRCC2 coding region have no potential effects on susceptibility to DTC. However, further studies with larger populations are required to confirm this conclusion.

    Metastatic differentiated thyroid carcinoma (DTC) with positive (131)I scintigraphy, but negative stimulated Tg (sTg) is relatively rare in clinical practice. The clinical characteristics of these patients were analyzed in the current study. A total of 3367 consecutive histologically proven DTC patients were analyzed retrospectively from January 2007 to June 2013. Tg negativity was defined as a sTg level of post-therapeutic (131)I-SPECT/CT positive and sTg negative (PTP-TN) constituting 2.1 % of all patients. Of these 71 patients, 2 (2.8 %) had bone metastasis, 11 (15.5 %) had lung metastasis, and 59 (83.1 %) had lymph node metastasis. Fifty-six patients had cervical lymph node metastasis (cLNM), and US was positive in 15 patients (26.8 %), while negative in 41 patients (73.2 %). When compared to patients with concordant positive results for sTg and (131)I scintigraphy, US showed a relatively lower positive rate in the detection of cLNM in PTP-TN patients (28.8 vs. 53.8 %; χ (2) = 6.70; P = 0.01). In conclusion, even with sTg post-therapy (131)I-SPECT/CT demonstrated an advantage in the detection of functioning metastasis despite low sTg levels in patients with metastatic DTC.

    ) and follicular carcinoma (FC). Comparison of carcinoma and adenoma with normal thyroid revealed 150 and 107 differentially expressed miRNAs. Most miRNAs were down-regulated and especially miR-199b-5p and miR-144 which were essentially lost in the carcinomas. Integration of the changed miRNAs with differentially...... expressed mRNAs demonstrated an enrichment of seed-sites among up-regulated transcripts encoding proteins implicated in thyroid tumourigenesis. This was substantiated by the demonstration that pre-miR-199b reduced proliferation when added to cultured follicular thyroid carcinoma cells. The down-regulated mi......RNAs in FC exhibited a substantial similarity with down-regulated miRNAs in anaplastic carcinoma and by gene set enrichment analysis, we observed a significant identity between target mRNAs in FC and transcripts up-regulated in anaplastic carcinoma. To examine the diagnostic potential of miRNA expression...

Methods The clinical data of 104 cases of differentiated thyroid carcino-ma treated by reoperation were retrospectively analyzed. Results The total residual cancer rate of thyroid tissues was 66. 35%, and the rate of lymph node residual cancer was 77. 89%. Univariate analysis showed that the patients were aged <45 years old, had a swollen past neck lymph nodes, residual or recurrence of primary cancer foci, and multiple cervical lymph node metastasis were significantly associated with the primary cancer (P<0. 05). Incidence of postoperative temporary larynx return nerve injury was 2. 88%, temporary hypocalcemia occur rate was 5. 77%, and there was no permanent laryngeal recurrent nerve injury and parathyroid injury. Conclusion DTC should guarantee the tumor resection thoroughly, especially for the treatment of cervical lymph nodes, and meanwhile complications such as recurrent laryngeal nerve and parathyroid injury should be prevented.

    Full Text Available Cytological diagnosis of hurthle cell lesions of thyroid is a diagnostic dilemma. Presence of hurthle cells on fine needle aspiration (FNA leads to a wide range of differential diagnosis including benign and malignant entities. The oncocytic variant of papillary thyroid carcinoma (PTC is one entity of the vast list of differentials of which very few cases have been reported to date. We report a case of oncocytic variant of PTC in a 28-year-old female diagnosed on cytomorphology. The findings of FNA smears of the first aspirate were not sufficient for a definitive diagnosis. Repeat FNA was done to rule out the possibility of autoimmune thyroiditis/thyroid neoplasm. The repeat FNA smears showed oncocytic cells present in papillary and loosely cohesive clusters. Many of the cells displayed nuclear features of PTC and the case was finally diagnosed as PTC; oncocytic variant. Thyroidectomy specimen revealed PTC; oncocytic variant with lymphocytic thyroiditis in the surrounding tissue. Thus, in cytology practice, concurrent autoimmune thyroiditis may pose a problem in diagnosis of PTC; oncocytic variant.

    Systemic chemotherapies for advanced or metastatic thyroid carcinomas have been of only limited effectiveness. For patients with differentiated or medullary carcinomas unresponsive to conventional treatments, novel therapies are needed to improve disease outcomes. The PubMed and Google Scholar search engines were used to identify publications and peer-reviewed meeting presentations addressing chemotherapy and targeted therapy for differentiated or medullary carcinoma. Multiple novel therapies primarily targeting angiogenesis have entered clinical trials for metastatic thyroid carcinoma. Partial response rates up to 30% have been reported in single agent studies, but prolonged disease stabilization is more commonly seen. The most successful agents target the vascular endothelial growth factor receptors, with potential targets including the mutant kinases associated with papillary and medullary oncogenesis. Two drugs approved for other malignancies, sorafenib and sunitinib, have had promising preliminary results reported, and are being used selectively for patients who do not qualify for clinical trials. Randomized trials for several agents are underway that may lead to eventual drug approval for thyroid cancer. Treatment for patients with metastatic or advanced thyroid carcinoma now emphasizes clinical trial opportunities for novel agents with considerable promise. Alternative options now exist for use of tyrosine kinase inhibitors that are well tolerated and may prove worthy of regulatory approval for this disease.

    Full Text Available INTRODUCTION: Papillary carcinoma is the most common malignant thyroid neoplasm. The effect of the concurrent presence of Hashimoto's thyroiditis and papillary thyroid carcinoma remains controversial. OBJECTIVE: To evaluate the association between Hashimoto's thyroiditis and clinicopathological parameters in thyroid papillary carcinoma cases, based on an historical institutional cohort analysis. METHODS: Cross-sectional study obtained from a historical cohort, including all cases submitted to thyroidectomy for papillary thyroid carcinoma in a single institution during an 11-year period study. RESULTS: A total of 417 patients with papillary thyroid carcinoma were enrolled; 148 (35.4% also had Hashimoto's thyroiditis. A female predominance among cases associated to Hashimoto's thyroiditis was observed. The thyroid tumor, in cases associated with Hashimoto's thyroiditis, had a smaller mean diameter, lower frequency of extra-thyroid extension, and earlier clinicopathological staging. CONCLUSIONS: A high proportion of papillary thyroid carcinoma cases are associated with Hashimoto's thyroiditis. There are associations among these cases with several histopathological factors already recognized for their prognostic value, which by themselves could impact outcomes.

    Evans, Carol; Tennant, Sarah; Perros, Petros

    2015-04-15

    Identification of differentiated thyroid cancer (DTC) is becoming increasingly common. Patients usually have an excellent prognosis. Most undergo total thyroidectomy, radioiodine ablation and treatment with suppressive doses of levothyroxine. Patients require long term follow-up which includes measurement of serum thyroglobulin (Tg). Interpretation of serum Tg requires knowledge of the concurrent thyroid stimulating hormone (TSH) concentration, as secretion is TSH dependant, and an awareness of the limitations of the methods used to measure it. These limitations include the heterogeneity of Tg in serum, the ability of assays to recognise forms of Tg secreted by a tumour, assay biases and not least the potential for interference in immunoassays for Tg from endogenous thyroglobulin antibodies (TgAbs) in patient serum. This review considers what the clinician wants to know and how Tg results can be interpreted in light of an awareness of assay limitations.

    2011-01-01

    Full Text Available Introduction. Although follicular thyroid carcinoma is a rare malignant tumor, up to 20% of the patients are threatened by potential complications resulting from infiltrating tumor growth into surrounding tissues. Case report. A 66- year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic examination showed a 8 cm hypoechoic nodule in the left lobe. Thyroid scintigraphy showed a cold nodule. CT scan and tracheoscopy showed tracheal infiltration without tracheal obstruction. An extended total thyroidectomy was done, with the left jugular vein, strap muscles and tracheal 2 cm long circular resection. The pathologist confirmed invasive follicular thyroid cancer. After the surgery the patient was treated with radioiodine therapy and permanent TSH suppressive therapy. The patient was followed with measurements of the thyroid hormone and serum thyroglobulin level every six months, as well as the further tests (chest xray, ultrasound of the neck and a whole body scintigraphy were done. After more than three years the patient had no evidence of the recurrent disease. Conclusion. Radical resection of the tracheal infiltrating thyroid cancer with circular tracheal resection and terminoterminal anastomosis followed by radioiodine therapy should be considered the treatment of choice.

    Objective: To investigate the relationships between angiogenesis and development, metastasis as well as prognosis of thyroid carcinoma. Methods:48 cases of thyroid carcinoma and 5 cases of thyroid adenoma were studied.Density of microvessels of the tumors were identified by immunohistochemical staining in formalin -fixed and paraffin-embedded sections with anti-CD34 monoclonal antibody, and counted microscopically (×200).Results :The mean value of MVD in tumors>2cm in diameter was (174.92±72.63)/field, while that in tumors≤2cm was ( 117.40± 39.95)/field ( t = 3.3298, P = 0.0026).The number of microvessels was also significantly different in respect to the histotype of the thyroid carcinomas, such as papillary thyroid carcinoma(PTC), follicular thyroid carcinoma(FTC)and medullary thyroid carcinoma(MTC) ( F = 14. 95, P = 0. 0001), but not significantly different in respect to patients'age nor sex ( P>0.05). Conclusions:By studying microvessel density (MVD) of thyroid arcinomas and correlated with their clinical features and biological behaviors, it is concluded that ngiogenesis is important in tumor growth and metastasis as well as prognosis of thyroid carcinomas. Measures to combat angiogenesis may be beneficial in the treatment for thyroid carcinomas.

    I-131-scintigraphy and serum thyroglobulin testing - if possible under stimulation of thyrotropin - are besides physical examination and ultrasonography crucial for the optimal follow-up of patients with well-differentiated thyroid carcinoma. This required physicians to withdraw patients from thyroid hormone suppression therapy (THST) for several weeks in order to raise endogenous TSH-levels. Clinical hypothyroidism often results in substantial patient discomfort, with sometimes major psychic alterations; the subsequent disability to work is occasionally an unpleasant consequence from an economical point of view. The temporary use of bovine, and for a short period of time human TSH is obsolete today because of a high risk of allergic reactions or the potential transmission of the Creutzfeldt-Jakob disease, respectively. Lately recombinant human TSH (rhTSH, Thyrogen {sup trademark}), a hormone that was developed with the help of genetic engineering techniques, is available; its pharmacological safety has been demonstrated in previous phase-I/II-studies. The results of a phase-III-study showed in the majority of patients a marked rise in thyroglobulin levels after rhTSH.

  17. Partial Laryngectomy with Cricoid Reconstruction: Thyroid Carcinoma Invading the Larynx

    Full Text Available Laryngotracheal invasion worsens the prognosis of thyroid cancer and the surgical approach for laryngotracheal invasion is controversial. In this paper, partial full-thickness excision of the cricoid cartilage with supracricoid laryngectomy and reconstruction of existing defect with thyroid cartilage are explained in a patient with papillary thyroid carcinoma invading the thyroid cartilage and cricoid cartilage without intraluminal invasion. Surgical indication should not be established by the site of involvement in thyroid carcinomas invading the larynx, as in primary cancers of the larynx. We think that partial laryngectomy according to the involvement site and the appropriate reconstruction techniques should be used for thyroid cancer invading the larynx.

  18. Anaplastic thyroid carcinoma: a new approach.

    Less than 10% of patients with anaplastic thyroid carcinoma survive 5 years when treated by operation and conventional irradiation, but survivors who are disease-free at 2 years appear to be cured. The administration of a small number of large radiation fractions (350 to 800 rads) failed to eradicate the local disease in 14 patients, all of whom died within 9 months. Hyperfractionation (100 rads qid at 3-hour intervals) caused complete tumour regression of 6 of 14 patients and partial regression in 7 others; the 1 patient whose tumour failed to respond was treated only once daily. However, the cost was high: two patients died of spinal cord necrosis and a third of pneumonitis due to the unexpected increase in radiation toxicity caused by the concurrent administration of Adriamycin. If an effective systemic treatment can be devised for this disease, hyperfractionation may be capable of eradicating the massive local tumour masses so characteristic of anaplastic thyroid carcinoma.

    Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.

    The purpose of this study was to explore the risk factors that were associated with central lymph node metastasis (CLNM) in patients with clinical nodal negative differentiated thyroid carcinoma (cN0 DTC) after prophylactic central neck dissection (pCND). The influence of pCND on TNM staging and recurrence risk stratification (RRS) in patients with cN0 DTC was also evaluated in our study. A total of 153 cN0 DTC patients in Guangdong general hospital who underwent thyroidectomy with pCND from March 2014 to October 2014 were enrolled in this study. The relations of CLNM with clinicopathologic characteristics of cN0 DTC were analyzed by univariate and multivariate logistic regression. The influence of pCND on migration of TNM staging and RRS in cN0 DTC was observed. In the present study, CLNM was found in 42.5% (65 of 153 cases) of patients with cN0 DTC. On univariate analysis, the age less than 45 years old, tumor size more than 2cm, pT staging, and a total number of central lymph nodes dissected more than 3 were significantly associated with CLNM (P0.05). On multivariate logistic regression, age3 (P=0.002) were significantly associated with CLNM. Because of the identification of CLNM in the implementation of pCND, 15 (9.8%) of 153 cN0 DTC patients were upgraded in TNM staging; all these patients were older than 45 years. Fifty-six patients (36.6%) developed higher RRS (from low to intermediate) after pCND. For younger patients (ageTNM staging (for patients with age≥45 years) and RRS.

    To report five cases of patients diagnosed with differentiated thyroid carcinoma (DTC) with uptake in the thymic area after high-dose treatment with I-131 and to evaluate the potential causes and therapeutic management. Five cases of young female patients with a mean age of 36.6 years (24-43) who had been treated with a mean dose of 106 mCi of I-131 (100-150 mCi) showing tracer uptake in the thymic area are reported. An I-131 whole-body scan (131I-WBS) was performed 7 days after therapeutic dose administration to each patient. Anterior and posterior planar images, followed by SPECT/CT of the head, neck and superior mediastinum were acquired in all patients. Thyroglobulin levels were measured with and without hormone replacement therapy in all cases. Samples taken from the superior mediastinum were sent to pathology for analysis, which confirmed the presence of thymic tissue. Two patients underwent elective total thymectomy due to the gross characteristics of the gland, local 131-I uptake, and high thyroglobulin levels. The remaining three patients had already undergone thymectomy as part of neck dissection during initial surgery, and no further invasive interventions were therefore performed. Pathological examination revealed no metastases in these five patients. Thymus visualization in young patients after administration of therapeutic doses of I-131 seems to be a more common finding than usually thought. Absence of metastasis in the thymus despite high thyroglobulin levels was confirmed in all cases. Based on these results, we suggest that a more expectant and less aggressive therapeutic approach could be used. We also suggest that I-131 therapy for DTC should be considered in classification of the potential causes of true thymic hyperplasia in the subgroup of patients recovering from a stressor.

  3. Follicular thyroid carcinoma mimicking meningioma: A case report

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Follicular thyroid carcinoma (FTC is a well-differentiated tumor which resembles the normal microscopic pattern of the thyroid. Although intracranial metastasis to the brain is frequent in adults, metastasis from FTC is very rare. Dural metastases mimicking meningioma have been documented in the literature now and then. However, cases arising from a FTC are again very rare. We report the case of a middle-aged lady who presented with progressive, painless left eye proptosis. She was noted to have a non-axial proptosis with dystopia, compressive optic neuropathy and exposure keratitis. She also had a painless swelling over the occipital region. She was initially misdiagnosed to have multiple foci of meningioma based on magnetic resonance imaging findings. Subsequent histopathological examination revealed presence of FTC. She was euthyroid but was found to have multiple small thyroid nodules by ultrasonography. Hence, the definite diagnosis of all dural masses must be histological wherever possible and thyroid carcinoma should be considered as a potential primary tumour in such presentations.

    2013-08-01

    An 82-year-old patient presented a progressively growing hard thyroid nodule, and left ptosis. Additionally, ophthalmologic evaluation revealed ipsilateral miosis, diagnostic findings of Horner syndrome. Computerized tomography revealed a 7.5-cm thyroid mass infiltrating the main neck vessels. Although clinical and imaging data were suggestive of poorly differentiated thyroid carcinoma, fine-needle aspiration led to the diagnosis of papillary carcinoma. Paliative care was proposed to the patient due to the advanced stage of the neoplasm and to significant comorbidities. Horner syndrome is an infrequent manifestation of thyroid disorders and benign etiologies are more often implied. Malignant thyroid neoplasms represent a rare cause of Horner syndrome. However, an appropriate and prompt diagnosis is paramount for timely treatment of rare thyroid malignancies.

    Although the thyroid gland is one of the most vascular organs of the body, metastatic disease in the thyroid is encountered infrequently. However, at autopsy, the incidence rate of thyroid metastasis ranges from 1.25% to 24%. The primary sites are the kidney, lung, breast, and gastrointestinal tract. We report a rare case of a hepatocellular carcinoma metastatic to the thyroid gland. The patient had multiple palpable masses in the anterior and left lateral neck along the internal jugular chain on physical examination 9 months after the initial diagnosis of liver tumor. These masses were confirmed as metastasis from hepatocellular carcinoma by ultrasonography-guided 16-G core needle biopsy. We discuss the sonographic findings of thyroid metastasis and their use as an additional aid for differentiating between unknown primary tumor and thyroid metastasis.

    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. Clinically, these carcinomas may show frequent recurrences but are associated with long

    Full Text Available Abstract Background Papillary thyroid microcarcinomas are tumors often found accidentally after thyroidectomy for other thyroid disorders. Methods Patients with enlarged lateral cervical masses, with unknown thyroid disease, found to have metastases from papillary thyroid carcinoma ≤10 mm in diameter, were compared to patients operated on for nodular or multinodular goiter, who were incidentally found to have papillary thyroid microcarcinomas. Results Group A included 24 patients with an enlarged lateral cervical mass whereas group B included 30 patients presenting with nodular or multinodular goiter. Patients in both groups underwent surgery. After thyroidectomy and lymph node dissection, pathology revealed multifocal papillary carcinomas of 1–10 mm, with invasion of the thyroid capsule and surrounding soft tissue in most of the cases in group A. Two patients presented with distant metastases at diagnosis which were surgically removed. During follow up, 3 patients (12.5% presented with new cervical metastases which were surgically removed or treated with additional radioactive iodine. At last follow-up, all patients were alive. In contrast, all patients in group B had unifocal papillary thyroid carcinoma 1–10 mm in maximum diameter, with no infiltration or extension into the adjacent tissue, or cervical lymph node metastases. Conclusion Two groups of papillary thyroid microcarcinomas characterized by different clinical and biological behaviours are identified. Significant differences were found between these groups concerning the age, tumor size, number of tumor foci, lymph nodes metastases and extrathyroidal extension of the tumor. Papillary thyroid carcinomas of small (≤10 mm size may have aggressive behaviour or be metastatic, and this subgroup should be treated and followed up as are other large, differentiated thyroid cancers.

  9. Follicular Thyroid Carcinoma Metastatic to the Kidney: Report of a Case with Cytohistologic Correlation

    2015-01-01

    Full Text Available Here we report a case of a 45-year-old female who underwent thyroidectomy for thyroid cancer and presented 20 years later with a left renal mass. CT-guided core biopsy was performed, and imprints and histologic sections of the biopsy showed cells resembling thyroid follicular cells with a background containing colloid. Immunohistochemistry revealed positivity for thyroglobulin and thyroid transcription factor 1, consistent with metastatic follicular thyroid carcinoma (FTC. The patient later underwent radical nephrectomy; histologic sections of the resected tumor revealed an encapsulated lesion morphologically similar to the biopsy specimen. Thyroid metastases to the kidney are extremely rare and are often detected during postthyroidectomy surveillance by elevation in thyroid hormone levels, 131I scintigraphy, or 18F-fluorodeoxyglucose uptake in positron emission tomography studies. Treatment involves total thyroidectomy, resection of the metastatic foci, and 131I therapy. The differential diagnoses of renal metastasis of FTC include the encapsulated follicular variant of papillary thyroid carcinoma (PTC, which possesses some of the nuclear features seen in conventional PTC but may occasionally be indistinguishable from FTC in cytologic preparations, and renal lesions such as benign thyroidization of the kidney and thyroid-like follicular carcinoma of the kidney, which mimic FTC in histologic appearance but do not stain with thyroid markers.

    Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.%目的 探讨caspase-10表达在甲状腺分化癌(DTC)发生、发展及预后中的作用.方法 37例DTC来自于2006年1月至2007年12月行甲状腺切除术患者.取DTC患者病理标本,链霉菌抗生物素蛋白-过氧化物酶连结法(S-P)染色,光镜下检测DTC患者caspase-10表达,分析caspase-10在DTC中的表达与临床病理特征之间的关系.取同期46例结节性甲状腺肿组织标本作为对照.结果 结节性甲状腺肿细胞质或细胞膜,可见到较多的棕色或黄色caspase-10表达颗粒,但在DTC中棕色或黄色表达颗粒不明显.caspase-10表达阳性率在DTC患者中为29.73%(11/37),在结节性甲状腺肿患者中为71.74%(33/46),二者比较差异有统计学意义(χ2=14528,P0.05).结论 caspase-10表达

  11. Warthin-like papillary thyroid carcinoma: a case report

    Directory of Open Access Journals (Sweden)

    Haeri H

    2013-02-01

    Full Text Available Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands.Case presentation: We report a 54- year- old man presented with bilateral thyroid masses. Histopathological study showed papillary structures lined by cells with eosinophilic granular cytoplasm and ground- glass nuclei with lymphoplasmacytic infiltration of the stalks.Conclusion: Warthin tumor-like papillary thyroid carcinoma could be mistaken for benign lymphoepithelial lesions such as Hashimoto thyroiditis, Hurthle cell tumors and tall cell variant of papillary carcinoma. Follow- up information on the previously reported cases has suggested that these tumors behave similarly to usual papillary carcinoma.

    The etiology of medullary thyroid carcinoma remains unknown. The aim of this study was to determine whether there is a significant association between medullary thyroid carcinoma and Hashimoto's thyroiditis in the histopathologic material of thyroidectomized patients. Retrospective cross-sectional study. In this study, we reviewed the medical records of all patients who underwent total thyroidectomy for different thyroid-related complaints between January 2000 and January 2012 at Jordan University Hospital-Amman, Jordan. To highlight relevant previously published studies addressing this topic, a literature search was conducted for English language studies reporting "medullary thyroid carcinoma" or "C-cell hyperplasia" in patients with Hashimoto's thyroiditis. Of the 863 patients with a mean age of 47.2 ± 12.3 years who underwent total thyroidectomy during the study period, 78 (9.04 %) were diagnosed with Hashimoto's thyroiditis, and 15 (1.74 %) had medullary thyroid carcinoma, 3 (20 %) of whom had coexistent Hashimoto's thyroiditis. A total of 683 (79.1 %) patients had benign thyroid disease, 67 (9.8 %) of whom had Hashimoto's thyroiditis. The difference between these rates was not statistically significant (p = 0.19). When examined by gender, 9 females had medullary thyroid carcinoma, 3 (33.3 %) of whom had coexistent Hashimoto's thyroiditis; by contrast, of 560 females with benign thyroid disease, 62 (11.1 %) had Hashimoto's thyroiditis (p = 0.04). Although this study population represents a small and single-institution experience, our results suggest that there might be an association between Hashimoto's thyroiditis and medullary thyroid carcinoma only in female patients who undergo total thyroidectomy.

    Recent investigations strongly suggest that Raman spectroscopy (RS) can be used as a clinical tool in cancer diagnosis to improve diagnostic accuracy. In this study, we evaluated the efficiency of Raman imaging microscopy to discriminate between healthy and neoplastic thyroid tissue, by analyzing main variants of Papillary Thyroid Carcinoma (PTC), the most common type of thyroid cancer. We performed Raman imaging of large tissue areas (from 100 × 100 μm2 up to 1 × 1 mm2), collecting 38 maps containing about 9000 Raman spectra. Multivariate statistical methods, including Linear Discriminant Analysis (LDA), were applied to translate Raman spectra differences between healthy and PTC tissues into diagnostically useful information for a reliable tissue classification. Our study is the first demonstration of specific biochemical features of the PTC profile, characterized by significant presence of carotenoids with respect to the healthy tissue. Moreover, this is the first evidence of Raman spectra differentiation between classical and follicular variant of PTC, discriminated by LDA with high efficiency. The combined histological and Raman microscopy analyses allow clear-cut integration of morphological and biochemical observations, with dramatic improvement of efficiency and reliability in the differential diagnosis of neoplastic thyroid nodules, paving the way to integrative findings for tumorigenesis and novel therapeutic strategies.

    The clinical usefulness of Tc-99m-MIBI in hypofunctioning thyroid nodules for detection of thyroid carcinoma is presented. Tc-99m-MIBI is a lipophilic cation and a non-specific radiopharmaceutical for tumour imaging. It has become an important imaging technique for the assessment of hypofunctioning thyroid nodules because of its high negative predictive value excluding malignant thyroid tumours. After injection of Tc-99m-MIBI either a single-phase protocol with late planar and SPECT images about 1-2 h post injection or a double-phase protocol with early (about 15-30 min p.i.) and late images (about 2 h p.i.) were reported. Findings include a reduced, an isointense or an increased Tc-99m-MIBI accumulation in the thyroid nodule in comparison to the paranodular thyroid tissue and in comparison to pertechnetate thyroid scintigraphy. A 'Match' between pertechnetate and Tc-99m-MIBI scintigraphy is a concordantly decreased uptake in the thyroid nodule in comparison to the normal thyroid gland. This finding has a negative predictive value of >97% to exclude differentiated thyroid cancer. A definite 'Mismatch' means a cold thyroid nodule on pertechnetate scintigraphy and an increased uptake of Tc-99m-MIBI in comparison to the MIBI-uptake of the paranodular thyroid tissue. The positive predictive value of this finding for malignancy varies between studies and is in the range of <10-65% (Cologne data: 19%) depending on the prevalence of malignant thyroid tumours in the patient population studied. An isointense uptake was not associated with thyroid malignancy according to 'Cologne' data. Further studies are desirable for better characterization of the method. (orig.)

    Ectopic thyroid tissue is a congenital disease caused by abnormal migration of thyroid in the embryonic stage. Malignant ectopic thyroid tissue is often misdiagnosed as a cyst of the thyroglossal duct. We treated 2 patients with papillary carcinoma in the anterior midline of the neck from May 1985 to Detober 2002.

    Full Text Available Abstract Introduction Double primary bronchogenic carcinoma and papillary carcinoma of the thyroid are extremely rare. We describe the case of a patient who underwent surgical resection for these two cancers. Case presentation A 56-year-old man presented to our hospital complaining of a cough with blood-tinged sputum. A slowly growing mass in the left lobe of the lung had been noted for about 1 year. He underwent video-assisted thoracic surgery of the left lower lobe and mediastinal lymph node dissection through an 8 cm utility incision. Pathology revealed a well-differentiated adenocarcinoma and the dissected lymph nodes were negative for malignancy. He also complained of a mass in his neck, which had grown slowly for over 5 years. A computed tomography scan of the neck revealed a left thyroid mass compressing the trachea towards the right side. There was no cervical lymphadenopathy. A left thyroid lobectomy was performed and pathology revealed a papillary carcinoma. Thus, he underwent a second operation to remove the right lobe of the thyroid. He underwent subsequent adjuvant chemotherapy. Conclusion In a review of the literature, it appears that there has only been one previously reported case of these two cancers, which was in Japan. The relationship between these two cancers is still unclear, and more case reports are required to determine this relationship.

    Objective: The aim of the study was to investigate the effects of short-term overt hypothyroidism on lipids after thyroxine-withdrawal in patients with iatrogenically induced hypothyroidism before radioiodine treatment for differentiated thyroid carcinoma (DTC). Methods: Thirty patients with a history of differentiated thyroid carcinoma on thyroid-stimulating hormone (TSH)-suppressive thyroxine replacement therapy were studied. Blood sample were taken before and 4 weeks after withdrawal of thyroxine substitution. Venous blood was drawn after an overnight fast and analyzed for serum free T4 (FT4), free T3 (FT3), thyroid-stimulating hormone (TSH), total cholesterol (TC), triglyceddes (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB). Fifty healthy people matched for age and gender were controls. Their blood samples were taken only once. Results: After thyroxine-withdrawal, the patients presented with increased serum TSH and low serum FT4 and FT3 levels compared with controls. Serum TG, TC, LDL, HDL, APOB and Lp(a) increased after thyroxine withdrawal, reaching statistical significant dif-ferences with previous evaluation. However, when compared to euthyroid controls, only TC, LDL and ApoB were increased when patients were hypothyroidism. No changes were observed in ApoA1 in patients dudng thyroxine withdrawal, or when comparing the values observed in patients to those of euthyroid controls. Conclusion: TG, TC, LDL, HDL, APO8 and Lp(a) were increased during short-term overt hypothyroidism.

    Full Text Available We present a case of Warthin-like papillary thyroid carcinoma in a 22-year-old woman and a review of the literature on the topic. The patient had the occasional discovery of a hypoechoic thyroid nodule of approximately 18 mm, characterized by irregular margins, hyperechoic spots, rich intra- and perilesional vascularization, and a suspicious enlarged right laterocervical lymph node. Fine-needle aspiration was performed for both lesions and the diagnosis of papillary thyroid carcinoma without lymph node involvement was made. The patient underwent thyroidectomy and central neck lymphadenectomy without complications. Histopathological examination suggested a Warthin-like papillary carcinoma of the thyroid gland, with all the removed lymph nodes being free of disease. The patient subsequently underwent iodine ablative therapy and she remains free of disease one year after surgery. Warthin-like papillary thyroid carcinoma is a recently described variant of papillary thyroid cancer that is frequently associated with lymphocytic thyroiditis. Morphologically, it resembles Warthin tumors of the salivary glands, with T and B lymphocytes infiltrating the stalks of papillae lined with oncocytic cells. Surgical and postoperative management is identical to that of classic differentiated thyroid cancer, while prognosis seems to be favourable.

    Full Text Available Graves′ disease with accompanying functioning nodules is known as Marine-Lenhart syndrome. Autonomously functioning thyroid nodules (AFTNs also within Graves′ thyroid tissue are almost always bening in nature. A 45-year-old man developed hyperthyroidism due to the coexistence of Graves′ disease and AFTN. Total thyroidectomy was performed. The hyperfunctioning nodule with centrally hypoactive foci detected by technetium-99m thyroid scanning was histologically diagnosed as papillary thyroid carcinoma that was 2.5 cm in diameter. We report the presence of papillary thyroid carcinoma within AFTN in patients with Marine-Lenhart syndrome, which has not been reported so far.

    Diffuse sclerosing papillary carcinoma (DSPC) is a variant of papillary thyroid carcinoma (PTC), but it shows more aggressive clinical course and a poorer prognosis than the other types of PTC. Most PTCs show a focal nodular pattern in the thyroid on the imaging modalities, but DSPC reveals a diffuse infiltrating configuration in the thyroid without any focal nodular lesion. To our knowledge, there are scant radiological reports of diffuse sclerosing variant of papillary thyroid carcinoma. In this report, we present the case of a patient with DSPC who showed the characteristic findings on sonography and computed tomography.

    The authors present a rare case of papillary carcinoma arising from the pyramidal lobe of the thyroid in a 54-year-old woman, who presented with a right submental palpable mass. An ultrasound evaluation depicted a 3 cm mixed echoic mass from the thyroid cartilage level without a focal lesion in the thyroid gland. Surgical specimens obtained during bilateral thyroidectomy confirmed papillary carcinoma of the pyramidal lobe. To the authors' knowledge, this is the first case report to describe papillary carcinoma arising from the pyramidal lobe of the thyroid gland

    Full Text Available OBJECTIVES: The aim of this study was to investigate the role of the interleukin-18 +105A/C and interleukin-10 -1082A/G germline polymorphisms in the development and outcome of differentiated thyroid carcinoma associated or not with concurrent thyroiditis. METHODS: We studied 346 patients with differentiated thyroid carcinomas, comprising 292 papillary carcinomas and 54 follicular carcinomas, who were followed up for 12-298 months (mean 76.10 ± 68.23 months according to a standard protocol. We genotyped 200 patients and 144 control individuals for the interleukin-18 +105A/C polymorphism, and we genotyped 183 patients and 137 controls for the interleukin-10 -1082A/G polymorphism. RESULTS: Interleukin-18 polymorphisms were not associated with chronic lymphocytic thyroiditis or any clinical or pathological feature of tumor aggressiveness. However, there was an association between the presence of interleukin-10 variants and chronic lymphocytic thyroiditis. Chronic lymphocytic thyroiditis was present in 21.74% of differentiated thyroid carcinoma patients, most frequently affecting women previously diagnosed with Hashimoto's thyroiditis who had received a lower 131I cumulative dose and did not present lymph node metastases. CONCLUSIONS: We conclude that the inheritance of a G allele at the interleukin-10 -1082A/G polymorphism may favor a concurrent thyroid autoimmunity in differentiated thyroid carcinoma patients, and this autoimmunity may favor a better prognosis for these patients.

    Full Text Available A radioiodoterapia tem conseguido desempenhar um papel significante no tratamento do carcinoma diferenciado de tireóide. A literatura é limitada em relação a possíveis efeitos secundários do 131I, embora o interesse tenha aumentado nesse campo. A importância de se saber mais sobre os efeitos mutagênicos da radiação em filhos de mães expostas ao 131I para tratamento do carcinoma diferenciado de tireóide é devida à possibilidade de ocorrência de abortos, anormalidades genéticas e aparecimento de malignidades nas crianças. Nesta revisão da literatura vários estudos têm demonstrado a segurança desse tipo de tratamento em mulheres na idade fértil, sendo apenas aconselhadas a evitar gravidez pelo período de, pelo menos, um ano após a administração da radioiodoterapia.Radioiodine therapy has attained a significant role in the treatment of differentiated thyroid cancer. The literature addressing possible secondary effects of 131I is limited, although there has been increasingly interest in this field. A more comprehensive understanding of the mutagenic effects of radiation on the offspring of women exposed to 131I is mandatory in view of the possibility of occurrence of miscarriages, congenital abnormalities and malignancies in these children. In this review, we found that many reports on safety of this type of treatment in female patients in reproductive age recommend that pregnancy should be avoided for at least one year after therapeutic administration of radioiodine.

    Medullary thyroid carcinoma accounts for approximately 1 to 2 % of all thyroid carcinoma cases. The most common route of dissemination is to locoregional lymph nodes. Distant metastases commonly affect bones, lungs, and liver. We present a case of a white woman with a 25-year history of medullary thyroid carcinoma on multiple medications including tyrosine kinase inhibitor therapy for the last 11 months, who exhibited unusual diffuse infiltration of advanced stage medullary thyroid carcinoma to her gastric mucosa. A 53-year-old white woman presented with increasing fatigue, loss of appetite, and severe epigastric pain radiating to her back. She had a history of medullary thyroid carcinoma (pT2pN1b), diagnosed 25 years ago and treated by complete thyroidectomy and repeated bilateral cervical lymph node dissection. Medical therapy included octreotide 20 mg every 4 weeks, which was switched to the tyrosine kinase inhibitor vandetanib 300 mg/day 11 months ago when computed tomography scanning revealed progressive mediastinal lymph node and diffuse and symptomatic pulmonary metastases. Of note, she demonstrated macroscopically stable pulmonary and mediastinal lymph node metastases; however, her calcitonin serum levels dramatically increased. Computed tomography scanning revealed a single new intrahepatic lesion (4 mm) as well as multiple (>10) new supraclavicular lesions suggestive of medullary thyroid carcinoma progress. As proven by gastric biopsy and immunohistochemical evaluation, her epigastric pain was explained by a diffuse infiltration of her gastric mucosa by metastatic medullary thyroid carcinoma. Subsequently, she rapidly deteriorated and died. The current case report shows for the first time an unusual metastatic infiltration of the gastric mucosa by medullary thyroid carcinoma. When treating these patients, it is important to include this differential diagnosis during follow-up.

    Follicular carcinomas are the second most common form of thyroid cancer, accounting for 10 to 20% of all thyroid cancers. Follicular carcinomas have a propensity to metastasize via the bloodstream, spreading to bone, lungs, liver, and elsewhere. We described the case of a 48-year-old woman who presented with swelling of the left pre auricular area, which was a consequence of a metastatic follicular carcinoma of the masticator space. Plain films showed ill defined erosive bony changes from the left condylar head to the mandibular notch. Contrast-enhanced CT images showed a well circumscribed round mass with well enhancement within left masticator space. On MR images, the mass was heterogenously hyperintense to the muscle on T2-weighted images and isointense or hyperintense to the muscle on T1-weighted images, and showed good enhancement on contrast-enhanced T1-weighted images. Upon microscopic examination, the metastatic mass was found to be composed of fairly uniform cells forming small follicles containing colloid, showing capsular and vascular invasion.

    The prognosis of metastatic thyroid carcinoma is dependent on the age of the patient, the histologic characteristics of the neoplasm, and the site of metastasis. A more favorable prognosis is found in patients less than 40 years old with follicular carcinoma and without any bony metastases. Metastatic thyroid carcinoma presenting as distal spinal cord compression is extremely rare. We report one such case and review the literature. As reported in the literature, the combination of decompressive laminectomy followed by total thyroidectomy and radioactive iodine therapy has proved to be effective in the treatment of patients with thyroid carcinoma metastatic to the distal vertebral bodies.

    Objective: To explore the efficacy of thyroid ultrasound (US) elastography in differential diagnosis of small thyroid nodules. Methods: This HIPAA-compliant study was approved by the Institutional Review Board and all patients provided written informed consent. Thirty-five patients with 38 small thyroid nodules as seen on transverse ultrasound image formed our study population. An US examination and a separate thyroid elastography examination with pulsation from the carotid artery used as the compression source were performed before fine-needle aspiration. Baseband US data were acquired for off-line elastography processing, where a semi-quantitative index for each nodule was calculated. The Kruskal–Wallis nonparametric rank sum test was used to assess equality of population means among the different types of thyroid nodules. Maximum likelihood estimation of the curve parameters for a binomial receiver operating characteristic (ROC) curve was performed. Results: Elasticity contrast index calculated with elastography was effective in distinguishing between small papillary thyroid carcinomas (PTMC, n = 8) and other lesions (n = 30) in small thyroid nodules (p = 0.0036). The area under the ROC curve for diagnosing PTMCs was 0.812 with a 95% confidence interval of 0.653–0.920. The cut-off value of ECI of 3.6 led to a sensitivity of 100% and a specificity of 60% for detecting PTMCs. Conclusion: Noninvasive evaluation of small thyroid nodules is possible using thyroid US elastography with in vivo compression to pick out the most suspicious thyroid nodules for fine-needle aspiration (FNA) and avoid FNA in benign nodules.

    We investigated the diagnostic capabilities of I-131, Tl-201, and Tc-99m-MIBI (hexakis-2-methoxyisobutyl- isonitrile scintigraphy for thyroid cancer metastases after total thyroidectomy over the entire body and for every locus before and after thyroid bed ablation. After total thyroidectomy of thyroid cancer, 36 cases were subjected to I-131 treatment 64 times. They consisted of 17 men and 19 women with 31 papillary carcinomas and 5 follicular carcinomas. Their ages were 22--75(an average of 60.5+/-12.3 years. I-131 scintigraphy(I-131, Tl-201 scintigraphy(Tl-201, and Tc-99m- MIBI scintigraphy (Tc-99m-MIBI were performed. We defined the metastases as those cases in which serum thyroglobulin (Tgincreased significantly or in which we were able to prove the lesions on CT (computed tomography, MRI (magnetic resonance imaging or bone scintigram. Three radiology medical specialists visually evaluated each scintigram and calculated the sensitivity, specificity, and likelihood ratio. For whole-body sensitivity, both Tl-201 and Tc-99m-MIBI were high before ablation and I-131 was high after ablation. Before ablation, the negative likelihood ratio was less than 0.1 for Tl-201 and Tc-99m-MIBI, while the positive likelihood ratio was more than 10 for Tl-201. After ablation, the positive likelihood ratio for I-131, Tl-201, and Tc-99m-MIBI was more than 10. The sensitivity of the mediastinum was appropriate, except for I-131 before ablation, and the sensitivity of the lung before and after ablation was inferior for either tracer. The specificity of the cervix for I-131 before ablation was markedly deteriorated, but it increased after ablation.

    Thyrotropin receptor (TSH-R), thyroglobulin (Tg), thyroperoxidase (TPO), thyroid specific transcription factor-1 (TTF-1), paired box 8 transcription factor (PAX-8), insulin like growth factor-1 (IGF-1) and estrogen receptor alpha (ERα) transcripts were determined by real-time PCR in follicular carcinoma and contralateral (CL) lobes, and healthy thyroid canine glands. Concentrations of TSH-R, PAX-8, and ERα mRNA were not different among groups; the carcinoma group had lower Tg and TPO mRNA than healthy and CL groups, while no differences were found between the two latter groups, suggesting that the carcinoma tissue presents an altered capacity to synthesize thyroid hormones. The transcription factor that promotes thyrocytes proliferation, TTF-1 as well as IGF-1, presented a greater mRNA expression in the CL group, suggesting that the CL lobe may function in a compensatory state.

    Fourier transform infrared (FT-IR) microscopy was used to image tissue samples from twenty patients diagnosed with thyroid carcinoma. The spectral data were then used to differentiate between follicular thyroid carcinoma and follicular variant of papillary thyroid carcinoma using principle component analysis coupled with linear discriminant analysis and a Naïve Bayesian classifier operating on a set of computed spectral metrics. Classification of patients' disease type was accomplished by using average spectra from a wide region containing follicular cells, colloid, and fibrosis; however, classification of disease state at the pixel level was only possible when the extracted spectra were limited to follicular epithelial cells in the samples, excluding the relatively uninformative areas of fibrosis. The results demonstrate the potential of FT-IR microscopy as a tool to assist in the difficult diagnosis of these subtypes of thyroid cancer, and also highlights the importance of selectively and separately analyzing spectral information from different features of a tissue of interest.

    Full Text Available The clinical behaviour of Hurthle cell carcinoma (HCC of the thyroid is variable and there are many controversies in the literature. Here, we summarize an up-to-date review of the literature on genetics, diagnosis (ultrasound scan, fine needle aspiration, frozen section, etc., and management. At presentation, treatment decision should be made by a multidisciplinary board. Recurrent HCCs are seldom curable despite salvage treatments, which include radioactive iodine ablation, radiofrequency ablation, ethanol ablation, external radiotherapy, and systemic therapy. Further research is needed to develop more efficacious systemic treatments. Currently, lenvatinib, sunitinib, and sorafenib are available. The completed and ongoing clinical trials for HCC are summarized

    This study was designed to evaluate the ultrasonographic (US) findings of medullary thyroid carcinoma (MTC) as compared to findings for papillary thyroid carcinoma (PTC). The study included 21 cases of MTC that were surgically diagnosed between 2002 and 2007 and 114 cases of PTC that were diagnosed in 2007. Two radiologists reached a consensus in the evaluation of the US findings. The US findings were classified as recommended by the Thyroid Study Group of the Korean Society of Neuroradiology and Head and Neck Radiology (KSNHNR) and each nodule was identified as suspicious malignant, indeterminate or probably benign. The findings of medullary and papillary carcinomas were compared with use of the chi-squared test. The common US findings for MTCs were solid internal content (91%), an ovoid to round shape (57%), marked hypoechogenicity (52%) and calcifications (52%). Among the 21 cases of MTC nodules, 17 (81%) were classified as suspicious malignant nodules. The mean size (longest diameter) of MTC nodules was 19 {+-}13.9 mm and the mean size (longest diameter) of PTC nodules was 11 {+-} 7.4 mm; this difference was statistically significant (p < 0.05). An ovoid to round shape was more prevalent for MTC lesions than for PTC lesions (p < 0.05). The US criteria for suspicious malignant nodules as recommended by the Thyroid Study Group of the KSNHNR correspond to most MTC cases. The US findings for MTC are not greatly different from PTC except for the prevalence of an ovoid to round shape.

    2005-01-01

    Full Text Available Secondary neoplasm of the thyroid mimicking a primary thyroid lesion is a rare finding, especially in an individual without a past history of malignancy. A case of squamous cell carcinoma metastatic to the thyroid (presenting as a solitary thyroid nodule, who had an unsuspected primary in the esophagus is described. Usually, multiple areas of the gland are involved in the secondary involvement of the thyroid. The clinical presentation of an apparently asymptomatic mass with neck lymphadenopathy, normal thyroid functions, and a cold nodule on 99mTcO4- thyroid scan can often lead to a misdiagnosis as primary thyroid neoplasm. The present case underscores the fact that due importance to the subtle signs and symptoms and a high degree of suspicion, whenever the histology is unusual for a thyroid primary, is needed and the workup should include ruling out other primary malignancies.

    Thyroid cancer is relatively a rare cancer; about 1% from all cancers: between 10 and 1591 of patients with differentiated thyroid cancer develop micro or macro-nodular pulmonary metastases. In this study we examined the characteristics and evolution after treatment of 10 patients with micro-nodular or miliary metastases of well-differentiated thyroid carcinoma. Total body scintigraphy with 131 iodine, chest X-ray or CT scan, and thyroglobulin assay were performed for all patients. The treatment was iodine 131 (3. 7 GBq). therapeutic 131 iodine scan was done for all patients seven days after the 131 administration. The effect of 131 iodine treatment was evaluated by means of changes in the number and size of lung metastases on the total body scintigraphy with 131 iodine and by serum thyroglobulin levels six months after 131 iodine ablation, they all received L-thyroxine (2,4 {mu}g/kg/j). The minimum duration of follow-up was 12 months. There were six females and four males within a range of 13-70 years old. Eight had papillary and two follicular thyroid cancer. These 10 patients benefited 131 iodine therapy. The effect of 131 iodine treatment and the prognostic values of the following variables mere examined: age at the time of 131 iodine. treatment and histological findings. The miliary was rarely diagnosed on the initial investigation. only in to o cases by 131 iodine scar. alter surgery. two cases by chest X-ray, and two cases by CT scan, the initial thyroglobulin levels was very high in seven cases, between 10 and 40 ng/ml in one case and less than 10 ng/ml in two cases. These results indicate that age, 131 iodine uptake. histological findings and the presence of other metastases are important factors in predicting the effects of 131 treatment for pulmonary metastases of well-differentiated thyroid carcinoma. Among all the variables studied. the best prognosis for survival was demonstrated by increased 131 uptake in pulmonary metastases and by early diagnosis

    The aim of report is to present a case of a rare diffuse sclerosing variant of a papillary thyroid carcinoma. A 15-year old girl referred for ultrasound examination because of painless thyroid swelling lasting 10 days before. An ultrasound of the neck showed diffusely changed thyroid parenchyma, without nodes, looking as lymphocytic thyroiditis Hashimoto at first, but with snow-storm appearance, predominantly in the right lobe. Positive thyroid peroxidase antibodies (TPO-AT) also suggested Hashimoto thyroiditis. Repeated US-FNAB (fine needle-aspiration biopsy) of the right lobe revealed diffuse sclerosing variant of papillary thyroid carcinoma and patient underwent total thyreoidectomy. Patohistologic finding confirmed diffuse sclerosing variant of a papillary thyroid carcinoma in the both thyroid lobes and several metastatic lymph nodes. Two months later patient recived radioablative therapy with 3700 MBq (100 mCi) of 1-131 followed by levothyroxine replacement. At the moment, patient is without evidence of local or distant metastases and next regular control is scheduled in 6 months. In conclusion, a diffuse sclerosing variant is rare form of papillary thyroid carcinoma that echographically looks similar to Hashimoto thyroiditis and sometimes could be easily overlooked.

    Full Text Available Papillary thyroid carcinoma is the most common differentiated type of thyroid malignancy. It is largely a loco-regional disease with a high tendency to metastasize to regional cervical lymph nodes. Distant hematogenous metastases are very rare and primarily include lungs and bones. Distant bone metastases are present in approximately 1.7% of patients with differentiated thyroid malignancy. Sternum, ribs, and spine are the most frequent sites of osseous metastases. Up to our knowledge, we report the first occurrence of an extra nodal metastasis of papillary thyroid carcinoma to a femoral bone presenting as a pathological fracture in a 21-year-old 37-week primigravida. We report this case because of its unusual site of metastasis and atypical presentation during pregnancy. Moreover, we briefly elaborate on the management of such uncommon cases.

    In this study, the objective was to evaluate the presence of estrogen receptors alpha and beta (ERalpha and ERbeta) in cases of papillary carcinoma of the thyroid gland and to assess the practicality of this test. Immunohistochemical stains were performed for both ERalpha and ERbeta, for evaluation of immunoreactivity in 90 papillary carcinomas. Three variables were evaluated in each sample: the intensity of the staining both nuclear and cytoplasmatic, and the spread of the stain over the sample. None of the histological samples showed immunoreactivity for ERalpha. Positive immunoreactivity results for ERbeta were found in tissue samples in 66.6% (60 cases). The study shows that ERbeta has no significant specification for differentiation between papillary carcinoma and other malignant lesions of the thyroid, while ERalpha is undetectable in this lesion. The ER testing in cases of papillary carcinoma of the thyroid gland is nonspecific and might be not necessary.

    To quantify and discuss the prevalence of unsuspected thyroid lymph node metastases discovered in specimens from neck dissection for head and neck squamous cell carcinoma (HNSCC) and discuss the impact on patient management. Retrospective study between May 2004 and January 2007. University hospital. Pathological analysis of cervical lymph node dissection performed during surgery for HNSCC in a total of 349 neck dissections in 266 consecutive patients. Twenty-one patients showed metastatic lymph nodes from thyroid cancer (prevalence 7.9%): 13 cases were metastatic from a papillary thyroid carcinoma and 8 cases from a follicular carcinoma. In 5 of the 21 patients, classical dissection was associated to recurrent nerve dissection and unilateral lobectomy; no thyroid carcinoma was found. Thirteen patients received radiotherapy for HNSCC. Follow-up comprised annual ultrasonographic examination of the neck and thyroid in these 21 patients. Total thyroidectomy was decided on in 5, with discovery of 3 micro-papillary thyroid carcinomas, in a single patient (complementary (131)I treatment). No thyroid carcinomas were found for the other 4 patients. No patients died from thyroid carcinoma during follow-up (mean: 41 months). The prevalence of lymph node metastasis from thyroid carcinoma in cervical lymph node dissection during treatment of HNSCC seems higher (7.9%) than rates reported in the literature (0.3 to 1.6%). This may be due to the histopathological methods employed. Management of patients should be discussed in the light of thyroid ultrasonography and prognosis of HNSCC.

    Full Text Available The published studies confirming the safety and efficacy of rhTSH for diagnostic purposes have led to an increased interest in its use for preparation for radioiodine (RI dose administration in patients with recurrent or persistent differentiated thyroid carcinoma (DTC. In order to establish the efficacy of RI therapy after rhTSH, we have reviewed 39 rhTSH-aided radioiodine treatment in a series of 28 DTC patients. Patients were divided into two groups: GI (n=17, with previous thyroid bed uptake and undetectable thyroglobulin (Tg levels under levothyroxine treatment and GII (n=11, with proven metastatic local or distant disease. Median follow-up after the first rhTSH-aided radioiodine treatment was 32 ± 13 months (range 8 to 54 months. Sixteen patients (94% in GI were rendered disease free and one patient was shown to have persistent disease. In GII, the post therapy whole body scan showed pathological uptakes in all cases: in four patients in lungs, in four in mediastinum and in three in lateral neck. In two patients with mediastinum uptake, Tg levels were undetectable after rhTSH. In the follow-up, two patients with lateral neck uptake were rendered disease free, four patients died (three due to thyroid cancer and five out of the remaining patients have persistent disease. In conclusion, rhTSH aided therapy was helpful to eliminate normal thyroid bed remnants in 16/17 (94% patients (GI. rhTSH stimulated Tg was undetectable in two patients with mediastinal metastasis. We believe that rhTSH is a good alternative to levothyroxine withdrawal for the treatment of DTC with radioactive iodine, increasing the quality of life in these patients. Caution should be recommended in the follow-up of unselected DTC patients only with stimulated Tg levels.Los estudios publicados que confirman la seguridad y eficacia de la TSH recombinante (rhTSH llevaron a un incremento en el interés para su uso como adyuvante terapéutico en el CDT (ablación o tratamiento

    In patients who present with advanced anaplastic thyroid cancer, airway management is difficult because of bilateral vocal cord paralysis or tracheal invasion by the tumor. Airway management can be extremely complex in these patients. This is the author's 25 year experience with 30 patients who presented with anaplastic thyroid cancer and acute airway problems. The patients' airway issues developed soon after presentation or a few months after treatment. Ten patients presented with initial symptoms of acute airway distress. All of these patients were treated with tracheostomy or cricothyrotomy. The 10 patients who presented with initial symptoms of acute airway distress died within 4 months. Eight of the remaining 20 patients developed bilateral vocal cord paralysis. Airway management for these patients depended on the extent of distant disease and the family's understanding of the advanced nature of the disease and the palliative efforts. The remaining patients had a palliative and supportive approach. Airway management was the most critical issue in patients who presented with anaplastic thyroid cancer and initial airway distress. Cricothyrotomy was helpful in avoiding acute airway catastrophe. It is important to distinguish between poorly differentiated and anaplastic thyroid cancer and lymphoma for appropriate airway management.

    SPECT/CT improves localization of single photon-emitting radiopharmaceuticals. To determine the utility of SPECT/CT in children with papillary thyroid carcinoma. 20 SPECT/CT and planar studies were reviewed in 13 children with papillary thyroid carcinoma after total thyroidectomy. Seven studies used I-123 and 13 used I-131, after elevating TSH by T4 deprivation or intramuscular thyrotropin alfa. Eight children had one study and five children had two to four studies. Studies were performed at initial post-total thyroidectomy evaluation, follow-up and after I-131 treatment doses. SPECT/CT was performed with a diagnostic-quality CT unit in 13 studies and a localization-only CT unit in 7. Stimulated thyroglobulin was measured (except in 2 cases with anti-thyroglobulin antibodies). In 13 studies, neck activity was present but poorly localized on planar imaging; all foci of uptake were precisely localized by SPECT/CT. Two additional foci of neck uptake were found on SPECT/CT. SPECT/CT differentiated high neck uptake from facial activity. In six studies (four children), neck uptake was identified as benign by SPECT/CT (three thyroglossal duct remnants, one skin contamination, two by precise anatomical CT localization). In two children, SPECT/CT supported a decision not to treat with I-131. When SPECT/CT was unable to identify focal uptake as benign, stimulated thyroglobulin measurements were valuable. In three of 13 studies with neck uptake, SPECT/CT provided no useful additional information. SPECT/CT precisely localizes neck iodine uptake. In small numbers of patients, treatment is affected. SPECT/CT should be used when available in thyroid carcinoma patients. (orig.)

    Human thyroperoxidase (hTPO) is critical for the accumulation of iodide in thyroid tissues. Poorly differentiated and anaplastic thyroid tumours which lack thyroid-specific gene expression fail to accumulate iodide and, therefore, do not respond to iodine-131 therapy. We consequently investigated whether transfer of the hTPO gene is sufficient to restore the iodide-trapping capacity in undifferentiated thyroid and non-thyroid tumour cells. The human anaplastic thyroid carcinoma cell lines C643 and SW1736, the rat Morris hepatoma cell line MH3924A and the rat papillary thyroid carcinoma cell line L2 were used as in vitro model systems. Employing a bicistronic retroviral vector based on the myeloproliferative sarcoma virus for the transfer of the hTPO and the neomycin resistance gene, the C643 cells and SW1736 cells were transfected while the L2 cells and MH3924A cells were infected with retroviral particles. Seven recombinant C643 and seven SW1736 cell lines as well as four recombinant L2 and four MH3924A cell lines were established by neomycin selection. They were studied for hTPO expression using an antibody-based luminescence kit, followed by determination of the enzyme activity in the guaiacol assay and of the iodide uptake capacity in the presence of Na{sup 125}I. Genetically modified cell lines expressed up to 1,800 times more hTPO as compared to wild type tumour cells. The level of hTPO expression varied significantly between individual neomycin-resistant cell lines, suggesting that the recombinant retroviral DNA was integrated at different sites of the cellular genome. The accumulation of iodide, however, was not significantly enhanced in individual recombinant cell lines, irrespective of low or high hTPO expression. Moreover, there was no correlation between hTPO expression and enzyme activity in individual cell lines. The transduction of the hTPO gene per se is not sufficient to restore iodide trapping in non-iodide-concentrating tumour cells. Future

  9. RAS AND p53 EXPRESSION IN HUMAN THYROID CARCINOMA

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective: To investigate the possible interaction between the ras and p53 genes over-expression in thyroid carcinoma, and whether there is a correlation between the ras and p53 over-expression and clinicopathological criteria. Methods: Eighty patients with thyroid lesions were examined for expression of ras and p53 genes by the labeled streptavidin biotin peroxidase (LSAB) method. Of these patients, 54 were diagnosed (average age: 39.9± 15.9 years) with malignant lesions. Of those included in the study, 31 has papillary carcinoma, 13 had follicular carcinoma, 7 had medullary carcinoma, 3 had undifferentiated carcinoma and 19 were stratified to stage I, 28 to stage II, 2 to stage III and 5 to stage IV according to TNM staging system. Twenty-six benign nodular thyroid disorders were studied as control. Results: Positive immunostain results for ras and p53 genes were statistically significant between thyroid carcinomas and benign disorders (90.7% vs 23%, 55.5% vs 30.7%, P<0.05). Both p53 and ras overexpressions coexisted in 30 thyroid carcinomas, and of these, 3 died and 5 had recurrences within 4 years. Conclusions: Activation of ras gene and inactivation of p53 gene were cooperatively associated in thyroid tumorigenesis. The concurrent overexpressions of ras and p53 could result in a poor prognosis.

    Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

    A cohort study was performed to investigate the carcinogenic effect of treating skin hemangioma with ionizing radiation during early childhood. This paper presents the incidence of differentiated thyroid adenomas and carcinomas after radiotherapy in this cohort. This study confirms that radiation treatment performed in the past for hemangioma during infancy increased the risk of thyroid carcinoma and adenoma. Patients treated with external radiotherapy or with Radium 226 applicators for hemangiomas have to be more specifically followed up because this is the subgroup in whom the highest doses were received by the thyroid gland (more than 90% of the radiation doses were higher than 100 mGy). They are therefore more at risk of developing thyroid cancer

    Full Text Available BACKGROUND Multinodular goitre or nodular hyperplasia or adenomatoid goitre is the most common thyroid disease, which occurs due to deficient iodine intake. Initial hyperthyroid states, followed by follicular atrophy and secondary changes like haemorrhage, calcification and cystic degeneration occurs in most of the cases. Longstanding cases of nodular goitre can be associated with carcinomas, usually follicular carcinomas, and rarely papillary carcinomas.[1] This study was done to know the incidence of coexisting malignancies, follicular and papillary carcinomas of thyroid, in longstanding nodular goitres of thyroid. METHODS All the cases of nodular goitres examined in the last two years were studied, including the thyroidectomy specimens and FNAC slides whichever was done. Extensive grossing of the thyroidectomy specimens was done to detect the possibility of malignancy in longstanding cases of nodular goitre of thyroid. Review of FNAC slides was done in cases where cytodiagnosis of coexisting malignancy was missed and detected in histopathological examination. RESULTS In the present study, conducted over a two-year period, out of 50 cases of thyroidectomy specimens of multinodular goitres studied, six cases were diagnosed to be having coexisting malignancy of thyroid, of which four were follicular carcinomas of thyroid and two were papillary carcinomas of thyroid. FNAC diagnosis of coexisting malignancy was initially missed in FNAC in two cases, i.e. one case each of follicular carcinoma and papillary carcinoma. These FNAC slides were reviewed and the foci of malignancies detected. CONCLUSION There is a possibility of malignancy of thyroid coexisting with longstanding multinodular goitre of thyroid, which should be kept in mind, while performing the needle biopsy and thorough examination of FNAC slides is needed to avoid missing the possible detection of the coexisting malignant lesion. Thyroidectomy specimens should be extensively grossed to

    Full Text Available Purpose: Papillary thyroid carcinomas (PTCs measuring 1.0 cm or less were separately defined as papillary thyroid microcarcinomas (PTMs by the World Health Organization, emphasizing on their benign behavior. However, some reported that PTMs may have aggressive behavior, can cause regional, or even distant metastases. But till now, the characteristics of PTMs were only reviewed and described by the clinicopathological parameters, and no analysis of PTM by the gene level is available. We report on the gene expression profiles of PTMs by the oligonucleotide microarrays and the results of comparative analysis with those of PTCs. Materials and Methods: The gene expression profiles of 25 pairs of PTMs and their normal thyroid tissue counterparts, and 11 pairs of PTCs and their normal counterparts, were analyzed by Affymetrix Human Genome U133A. Data were analyzed by the SAM and the DAVID 2008 program to detect differentially expressed genes in supervised sample classification. Results: Two-hundred thirteen statistically significant up-regulated genes and -183 significant down-regulated genes of PTMs compared with their normal counterpart thyroid tissues, which were mainly cell adhesion-related genes and immune response genes, were detected. Two-hundred sixty-one up-regulated and -157 down-regulated genes of PTCs were also detected. In the comparative analyses of gene expression profiles of PTMs and PTCs, no significant difference was found. Conclusion: PTM should not be considered as the simple occult indolent thyroid cancer, but as the earlier stage of disease which eventually evolves into PTC, because the gene expression profiles of PTMs were not different from those of PTCs.

  17. WARTHIN TUMOR LIKE PAPILLARY CARCINOMA OF THYROID: A RARE OCCURENCE

    2015-12-01

    Full Text Available INTRODUCTION Among the thyroid cancers, papillary carcinoma is the most common type. Warthin tumor like papillary carcinoma of thyroid is a rare variant of papillary carcinoma. The distinguishing feature of this rare variant is papillary formations lined by tumor cells with oncocytic cytoplasm with nuclear features of papillary carcinoma and lymphoplasmacytic infiltrate in the papillary stalks with striking histological resemblance to Warthin’s tumor of salivary glands. A 46 years old female with complaints of painless swelling of the neck for four years and gradually increasing in size, measuring 3x2.5 cm on the right lobe of the thyroid gland. The swelling moved with deglutition, non-tender and firm to hard in consistency. Thyroid function was within normal limits. FNAC suggested a diagnosis of oxyphilic variant of papillary carcinoma of thyroid. It showed syncytial aggregates, sheets of cells and few papillary structures with focal nuclear crowding. The patient underwent bilateral total thyroidectomy and neck dissection. Microscopic examination showed predominantly follicles and small papillary structures lined by cells having eosinophilic cytoplasm and clear nucleus. There was lymphoid stroma in the core of papillae and interfolllicular areas. Hyalinized collagen, dystrophic calcification and follicles without colloid matter infiltrating the hyalinised area were seen. No lymphovascualr tumour embolization were noted. This tumor is found more commonly in women with Hashimoto’s thyroiditis. The prognosis is favourable as conventional papillary carcinoma. About 8% of Warthin’s tumor are detected in extraparotid locations.

    Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) was first described by Chan et al in 1991. It is characterized by nest or strands of epidermoid tumor cells with squamous differentiation, rare mucous cells, prominent sclerotic stroma, eosinophilic and lymphoplasmacytic infiltration, and a background of chronic lymphocytic thyroiditis in the non-neoplastic thyroid gland. It is important to recognize SMECE of thyroid and differentiate it from squamous cell carcinoma or other neoplasms with squamous differentiation/metaplasia. In published cases, the SMECE of thyroid gland predominantly occurs in women. We report a case of SMECE of thyroid in a 45-year-old male patient. All cases in male patients were Caucasian described in English literature, and our case is the first one in Asian.

    Using{sup 123}I for diagnostic purposes avoids the risk of stunning for subsequent radioiodine treatment and affords an excellent image quality. In this study we assessed the role of{sup 123}I in comparison with{sup 131}I post-treatment imaging in patients with thyroid cancer. We compared a total of 292{sup 123}I scans with their corresponding post-treatment{sup 131}I images. Patients received a therapeutic dose of{sup 131}I following diagnostic scanning with 50-111 MBq of{sup 123}I. All patients were in a hypothyroid state (>30 {mu}IU/l) before radioiodine administration for either diagnostic or therapeutic purposes. In 228 out of 263 patients with a positive diagnostic scan,{sup 123}I whole-body scan findings were concordant with those of corresponding post-treatment{sup 131}I images (concordance rate 87%). However, there were 44 additional foci of abnormal uptake on post-treatment{sup 131}I scans in 22 discordant cases with no impact on therapeutic management of the patients. In 13 patients, there was at least one new site on post-treatment images that had been missed on pretreatment{sup 123}I images. Twenty-nine patients with a negative diagnostic scan were treated with{sup 131}I owing to a high serum thyroglobulin level (range 11.3-480 ng/ml). Radioiodine uptake sites were seen in eight post-treatment scans. In 21 pairs of whole-body scans, both the pre- and the post-treatment scan were negative (concordance rate 72.4%). {sup 123}I scanning is comparable to high-dose{sup 131}I post-treatment imaging in thyroid carcinoma patients, and {sup 123}I offers excellent image quality as a diagnostic agent. It avoids disadvantages such as stunning before treatment and delivery of a high radiation dose to patients. (orig.)

The incidence of papillary thyroid carcinoma (PTC, especially small tumors is rapidly increasing during past three decades. At the time of diagnosis, the incidence of lymph node metastases (LNM ranges from 80 to 90%. During the last 15 years, LNM were recognized as bad prognostic factor for both local-regional relapse (LRR and cancer specific survival.

    Aim: To evaluate the ultrasound (US) features of the diffuse sclerosing variant of papillary carcinoma (DSVPC) of the thyroid, with histopathological correlations. Materials and methods: The US and histopathological findings of six patients with surgically proven DSVPC of the thyroid were retrospectively assessed. Results: Most of cases showed diffuse, scattered microcalcifications with or without associated masses and underlying heterogeneous hypoechogenicity at the site of the DSVPC in the thyroid. At ultrasound, scattered microcalcifications and heterogeneous hypoechogenicity seen in the DSVPC correlated to psammoma bodies and lymphocytic infiltration at histopathological review. Conclusion: DSVPC of the thyroid usually manifested as diffuse scattered microcalcifications and associated suspicious mass on ultrasound. These findings are not specific for the DSVPC of the thyroid. However, in relatively young patients with suspicious masses associated with underlying diffuse scattered microcalcifications on US, the possibility of DSVPC should be included in differential diagnosis.

    The aim of this article was to describe rarely occurred carcinoma adenoides cysticum located in the larynx, trachea and thyroid. Epidemiology, clinical course and medical therapy was demonstrated. In reported case concerning 65-year old woman early bilateral paresis of vocal folds was observed as results of the perineural infiltration. That caused sudden laryngeal dyspnea. It is important to pay attention on local extensiveness of neoplasm. Besides changes in larynx, neoplastic infiltration was found in trachea, preesophageal tissues and right lobe of thyroid. For above reasons there is no possible to exclude thyroid as a primary tumor of carcinoma adenoides cysticum.

    Full Text Available We report a rare case of papillary thyroid carcinoma incidentally found within a branchial cleft cyst. Only four other cases have been described in the literature. A total thyroidectomy and selective neck dissection was performed, and no evidence of occult primary disease was found after review of fine sections. Branchial cleft cysts are the most common lateral neck masses. Ectopic thyroid tissue within a branchial cleft cyst is an unusual phenomenon, and papillary thyroid carcinoma arising from this tissue is extremely rare. Clinicians are left with a diagnostic dilemma when presented with thyroid tissue neoplasm within a neck cyst in the absence of a thyroid primary—is this a case of metastatic disease with a missed primary or rather carcinoma arising in ectopic thyroid tissue? A thorough discussion of the etiologies of these lateral neck masses is reviewed including the embryogenesis of thyroid tissue in a branchial cleft cyst. The prognosis of patients with papillary thyroid carcinoma in lateral neck cysts without a primary site identified appears to be good following excision of the cyst and total thyroidectomy. Other management recommendations regarding these unique lateral neck malignancies are also presented.

    Diffuse sclerosing papillary thyroid carcinoma (DSPTC) is a relatively rare variant of papillary thyroid carcinoma with distinct histological features, radiological characteristics, and biological aggressiveness. Compared with conventional papillary thyroid carcinoma, DSPTC is characterized by scattered microscopic tumor islands, diffuse fibrosis, calcification, and abundant lymphocytic aggregation. A preoperative diagnosis is challenging in the absence of nodules and scanty fine needle aspiration cytology samples. We describe a unique DSPTC patient, an 18-year-old woman who presented with a neck mass that grew slowly for 2 years. The palpable neck mass was nontender, well defined, firm, and unmovable. Laboratory studies showed normal thyroid function and positive autoimmune markers: antithyroglobulin antibody = 1:1600 and antimicrosomal antibody = 1:1600. A neck ultrasound showed diffusely prominent microcalcifications with one small vague nodule. Hashimoto's thyroiditis with an accompanying malignancy was suspected. Based on the result of intraoperative pathology reports, the patient was given a total thyroidectomy. Lymph node dissection and histological analysis revealed bilateral DSPTC in addition to lymphocytic thyroiditis in nonmalignant areas of the thyroid. Clinical and histological diagnostic challenges usually occur when DSPTC presents with a diffuse thyroid enlargement, dispersed microscopic tumor islands (frequently without mass formation), extensive fibrosis, and abundant lymphocytic infiltration mimicking thyroiditis.

    Cutaneous metastasis of visceral tumors accounts for 2% of skin tumors. We report the case of a 71-year-old male with a smoking history who presented to dermatology department with a violaceous nodule of the right sideburn skin. The lesion was interpreted as an adenocarcinoma that was completely excised and was suspicious for a metastasis. There was a recommendation for additional work-up. At a different institution, a positron emission tomography scan showed a left hilar mass and uptake in the right thyroid. He was then referred to our hospital for tissue diagnosis. Mediastinoscopy with biopsy of the left hilar mass showed metastatic follicular thyroid carcinoma. Subsequently, a thyroid fine needle aspirate showed suspicion for malignancy with similar morphology. Thyroidectomy and central neck dissection showed right thyroid papillary carcinoma extending to one margin and involving the lymph nodes. The left hilar metastasis mass resection showed similar lymph node findings. A re-review of the sideburn excision revealed similar histopathology to the thyroid and mediastinal resection. This case illustrates the opportunity of considering metastatic thyroid carcinoma to skin even in cases which lack the classic cytologic and architectural features of papillary thyroid carcinoma follicular variant.

    Objective: To explore the clinical and pathological differences between papillary thyroid carcinoma (PTC) with Graves' disease (GD) and PTC with Hashimoto's thyroiditis (HT). Methods: A total of 33 PTC patients with GD and 132 PTC patients with HT in the First Affiliated Hospital of China Medical University from January 2009 to December 2015 were enrolled. The clinical and histopathological data were analyzed. Results: The average serum concentration of thyroid stimulating hormone (TSH) of PTCs with GD was significantly lower than PTCs with HT [0.01 (0, 0.10) mU/L vs 2.28(1.51, 3.14) mU/L, Pdisease [12.1%(4/33) vs 11.4% (15/132), P=1.00], papillary thyroid micro-carcinoma (PTMC) [60.6% (20/33) vs 60.6%(80/132), P=1.00]and classic PTC in all its variant patterns [81.8%(27/33) vs 75.0%(99/132), P=0.36]. The age (P<0.01, OR=0.95, 95%CI: 0.92-0.98) and PTMC (P<0.01, OR=0.30, 95%CI: 0.13-0.67), rather than TSH (P=0.08) were independently correlated with LNM. Recurrence rate of PTC with GD was significantly lower than PTC with HT (log-rank test, P=0.03). In Cox proportional hazards regression model, variant pattern of PTC was independently correlated with recurrence rate (P<0.05). Conclusions: GD with PTC wasn't different from HT concomitant with PTC, except for thyroid function test. In addition, recurrence rate of PTC with GD was lower than that of PTC with HT after controlling TSH in the same level.

    Full Text Available Papillary thyroid carcinoma (PTC is the most common thyroid malignancy, accounting for 70%–80% of all thyroid malignancies. It is biologically indolent and has an excellent prognosis. Variations in histopathologic patterns are known to influence prognosis and often result in a diagnostic dilemma. We report an unusual case of a 35-year-old female with papillary carcinoma of a thyroid isthmus showing anastomosing channels on histopathology, a distinctive pattern that has not been described in PTC. Similar to tumor cells, the lining cells of these channels were also positive for thyroid transcription factor 1, thyroglobulin, and cytokeratin-19 and negative for CD34 and CD31. The diagnosis of PTC should rely on nuclear morphology rather than architecture. Pathologists should be aware of different variants because some of these variants show aggressive behavior and poor outcome. The present report highlights the distinctive pattern of PTC, recognition of which is important to avoid any diagnostic pitfall.

    The presence of pleomorphic tumor giant cells in thyroid carcinomas of follicular cell origin is always worrisome for the pathologist as they first of all refer to anaplastic carcinoma, one of the most aggressive human malignancies. However, non-anaplastic pleomorphic giant cells are well described in other thyroid diseases, most often benign. In this paper, we describe four cases of papillary thyroid carcinoma displaying pleomorphic tumor giant cells with features that differ from those of anaplastic carcinoma. Pleomorphic giant cells were admixed with the underlying thyroid carcinoma and constituted from 5% to 25% of the tumor. Cytologically, they had an abundant eosinophilic cytoplasm with large and irregular nuclei. Compared to pleomorphic giant cells of anaplastic carcinoma, they reproduced the growth pattern of the underlying carcinoma, had a low mitotic index without necrosis or inflammation, and were reactive with thyroglobulin and thyroid-specific transcription factor-1 and strongly and diffusely positive for cytokeratin AE1/AE3. After 16-84 months of follow-up, patients are relapse-free and still alive. These cases show that pleomorphic tumor giant cells arising in papillary thyroid carcinomas do not always represent dedifferentiation and progression to anaplastic carcinoma. Distinction among these processes is critical as their treatment and prognosis are very different.

    It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, or may involve the whole thyroid gland diffusely. However, diffuse metastasis of gastric cancer to the thyroid is extremely rare. Here, we report a case of a 74-year-old woman with diffuse infiltration of gastric adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in the thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy with biopsy and fine-needle aspiration cytology of the thyroid. An 18F-FDG PET/CT revealed multiple lesions with increased uptake, including the bilateral thyroid gland. On thyroid ultrasound examination, diffuse enlargement with internal heterogeneity and hypoechoic reticular lines was observed. On color Doppler imaging, a blood-flow signal was not detected in these hypoechoic lines. These findings were similar to those of diffuse metastases caused by other primary cancers, such as lung cancer, as reported earlier. Therefore, the presence of hypoechoic reticular lines without blood-flow signals is probably common to diffuse thyroid metastasis from any origin and an important diagnostic finding. This is the first report to show detailed ultrasound findings of diffuse gastric cancer metastasis to the thyroid gland using color Doppler.

    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.

    Full Text Available Abstract Introduction Thyroglossal duct carcinoma is a very rare finding and its presentation is similar to that of a benign cyst, which is a relatively common developmental abnormality that may manifest as a midline, neck mass. In general the diagnosis of thyroglossal duct carcinoma is based on the pathologic examination of the mass, but needle aspiration cytology, ultrasound and computed tomography play a role in the differential diagnosis of malignancy. Case presentation A further case of thyroglossal duct carcinoma and concurrent thyroid carcinoma with locoregional lymph node metastases affecting a 40-year-old woman followed up for 4 years is presented and discussed. Conclusion Sistrunk's surgical technique must always be the initial treatment, but in case of carcinoma further surgery, that is, thyroidectomy with or without lymph node dissection, and treatment with radioactive iodine have to be considered according to the microscopic and clinical findings. Accurate pre-operative clinical and radiological evaluation should be performed in order to plan surgical strategy.

    The aim of these studies was to evaluate the possibility of treating differentiated thyroid cancer by BNCT. These carcinomas are well controlled with surgery followed by therapy with {sup 131}I; however, some patients do not respond to this treatment. BPA uptake was analyzed both in vitro and in nude mice implanted with cell lines of differentiated thyroid carcinoma. The boron intracellular concentration in the different cell lines and the biodistribution studies showed the selectivity of the BPA uptake by this kind of tumor.

    伴随甲状腺癌发病率的升高,接受外科治疗的甲状腺癌患者也随之增多,这其中绝大部分为分化型甲状腺癌患者。由于分化型甲状腺癌远期疗效好,治愈率高,容易忽视术前分期和术式选择的重要性,导致部分患者手术效果欠佳,术后无法正常进行131 I治疗以及远期疗效的评估,甚至可能使患者接受多次手术治疗,增加了手术并发症的发生率。因此,正确的术前分期和术式选择除了可以获得满意的手术疗效外,还可以为后续的131 I治疗以及远期评估起到积极的推动作用,并可降低患者的再次手术率,降低手术并发症的发生率。%With the increasing incident of thyroid cancer , many more thyroid cancer patients received surgical treatment , most of whom are diagnosed as differentiated thyroid cancer . However , pre-operative staging of tumor and surgical methods are not always chosen carefully because long -term outcome is considerable good .Inappropriate surgical methods might lead to poor clinical outcome , including unable to receive 131 I treatment and imprecise post-operative assessment .More seriously, the patient might require reoperation with increasing complications .Therefore, accurate pre-operative staging of tumors and appropriate surgical treatment would yield satisfactory outcome and benefit for long term assessment and post-operative 131 I treatment. Furthermore, the patients might have less chance for reoperation and post-operative complications .

    Thyroid gland tumors represent 1% of malignant tumors. In Italy their incidence is in constant growth. The aggressiveness depends on the histological type. The relative non-aggressive grade of different forms of tumors is the basis for discussing the treatment of choice: total thyroidectomy vs lobectomy with or without lymphadenectomy of the sixth level in the absence of metastasis. Authors report about their experience, and they advocate, given the high percentage of multicentric forms, total thyroidectomy as treatment of choice.

    To emphasize the importance of genetic studies in family members and early prophylactic thyroidectomy in oncogene mutation carriers in the management of familiar medullary thyroid carcinoma. A retrospective review of families with familiar medullary thyroid carcinoma treated at our center in the last 7 years was performed. We identified a total of 7 families who has isolated prevalences with thyroid malignancies. Forty members of the 7 families were screened for gene RET mutations. Prophylactic total thyroidectomy was performed in every RET mutation gene carriers. In all families the index case were patients with medullary thyroid carcinoma presenting at a mean age of 37.25 years (range 23-42). The RET oncogen mutation was in codon 634 in exon 11 (multiple endocrine neoplasia type 2A) in all these patients. Fourteen gene carriers were identified with a mean age of 20 years (range 7-37), eleven of whom had medullary thyroid carcinoma at the time of surgery. Five of the gene carriers were children, with a mean age of 11 years (range 7-16), four of whom had microcarcinoma and one had metastatic carcinoma at the time of surgery. After surgery no hypoparathyroidism or recurrent nerve paralysis were documented. No pediatric patient has presented with phaeochromocytoma or hypoparathyroidism to date Four of the five children have normal calcitonin levels (< 2 pg/ml) and they are free of disease. The one who presented metastatic carcinoma has recurrent disease and is awaiting surgical treatment. Genetic studies of family members related to patients with familiar medullary thyroid carcinoma and RET mutations is indispensable. The RET mutation in codon 634 exon 11 was found to be the most frequent association. Prophylactic thyroidectomy is the only curative treatment and has minimal complications when performed by expert surgeons. Early thyroidectomy is recommended since distant metastatic spread can occur at early age.

    Elevated levels of reactive oxygen species (ROS) have been proposed as a risk factor for the development of papillary thyroid carcinoma (PTC) in patients with Hashimoto thyroiditis (HT). However, it has yet to be proven that the total levels of ROS are sufficiently increased to contribute to carcinogenesis. We hypothesized that if the ROS levels were increased in HT, ROS-related genes would also be differently expressed in PTC with HT. To find differentially expressed genes (DEGs) we analyzed data from the Cancer Genomic Atlas, gene expression data from RNA sequencing: 33 from normal thyroid tissue, 232 from PTC without HT, and 60 from PTC with HT. We prepared 402 ROS-related genes from three gene sets by genomic database searching. We also analyzed a public microarray data to validate our results. Thirty-three ROS related genes were up-regulated in PTC with HT, whereas there were only nine genes in PTC without HT (Chi-square p-value < 0.001). Mean log2 fold changes of up-regulated genes was 0.562 in HT group and 0.252 in PTC without HT group (t-test p-value = 0.001). In microarray data analysis, 12 of 32 ROS-related genes showed the same differential expression pattern with statistical significance. In gene ontology analysis, up-regulated ROS-related genes were related with ROS metabolism and apoptosis. Immune function-related and carcinogenesis-related gene sets were enriched only in HT group in Gene Set Enrichment Analysis. Our results suggested that ROS levels may be increased in PTC with HT. Increased levels of ROS may contribute to PTC development in patients with HT.

    The fibrous variant of Hashimoto thyroiditis is uncommon, accounting for approximately 10% of all cases of Hashimoto thyroiditis. We report a case of this variant that behaved like a malignant neoplasm. The patient was a 69-year-old man who presented with a right-sided anterior neck mass that had been rapidly growing for 2 weeks. Fine-needle aspiration cytology revealed clusters of large multinucleated cells suggestive of an anaplastic carcinoma. A week after presentation, we ruled out that possibility when the mass had shrunk slightly. Instead, we diagnosed the patient with an acute exacerbation of Hashimoto thyroiditis on the basis of laboratory findings. We performed a right thyroid lobectomy, including removal of the isthmus, to clarify the pathology and alleviate pressure symptoms. The final diagnosis was the fibrous variant of Hashimoto thyroiditis, with no evidence of malignant changes. Physicians should keep in mind that on rare occasions, Hashimoto thyroiditis mimics a malignant neoplasm.

    Full Text Available Carcinoma lower oesophagus metastasizing to thyroid occurs rarely. We report the case of a 56-year-old male who was referred for evaluation of dysphagia in whom such an occurrence has been documeneted. Clinically patient had palpable cervical lymphadenopathy. There was no thyroid swelling. Upper gastro-intestinal endoscopic biopsy revealed squamous cell carcinoma of lower third oesophagus. Fine needle aspiration cytology (FNAC from the right cervical lymph node also revealed squamous cell carcinomatous deposits. Patient was then evaluated by integrated whole-body positron emission tomography-computed tomography using 18F fluorodeoxyglucose which revealed metabolic activity in thyroid gland. Ultrasound guided FNAC from thyroid shown metastatic squamous cell carcinomatous deposits which was further confirmed by imunocytochemistry. We present this case because of its exceedingly rare occurrence and poor prognosis.

    Full Text Available Abstract Background Thyroid gland derives from one median anlage at the base of the tongue, and from the two fourth branchial pouches. A number of anomalies may occur during their migration. These can be in form of ectopic tissues, which are frequently found along the course of thyroglossal duct and rarely in other sites, many of these may develop same diseases as the thyroid gland. Case presentation A 36-years-old female presented with a 3 month history of left side neck mass. The mass disappeared following aspiration of brown colored fluid, which on cytological examination showed cells with nuclear irregularities that warranted the resection of the lesion. The histology demonstrated a thyroid papillary carcinoma arising within the branchial cyst. Thereafter, the patient underwent a total thyroidectomy with central lymph nodes dissection. Histology showed a multifocal papillary carcinoma with central lymph nodes metastases. Only four cases of primary thyroid carcinomas in neck branchial cyst have been described so far. Conclusion In a lateral cystic neck mass, although rare, occurrence of ectopic thyroid tissue and presence of a papillary thyroid carcinoma should be kept in mind.

    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.

    Full Text Available Defining the histologic variant of thyroid carcinoma is an important clinical implication as their progression, recurrence, aggressiveness, and prognosis differ. Warthin-like variant is one of the rarest histologic variants of papillary thyroid cancer. A 36-year-old female sought consult for assessment of a painless right neck tumor. High-resolution neck ultrasound revealed a right hypoechoic, 1.71 × 1.05 cm thyroid nodule. Ultrasound-guided fine-needle aspiration biopsy report was a Bethesda grade III. Thyroid function tests showed Hashimoto’s thyroiditis. The patient underwent right hemithyroidectomy. Microscopically, the tumor was composed of papillae lined by cells with eosinophilic cytoplasm, nuclear chromatin clearing, grooves, and pseudoinclusions and a characteristic lymphoplasmacytic infiltrate of the papillae cores. Extension into the perithyroidal soft tissue and 3 ipsilateral lymph nodes was found to be positive for cancer. Warthin-like variant is an uncommon and relatively unknown variant of papillary thyroid carcinoma that has been usually associated with an excellent prognosis. Interestingly, BRAF mutations have been reported to be present in up to 75% of the patients. It is frequently associated with Hashimoto’s thyroiditis and presents unique morphological features that make it recognizable on histologic examination. The cytological diagnosis is difficult to assess due to the overlap in its findings with the classical variant and Hashimoto’s thyroiditis.

    Thyroid carcinoma has the ability to concentrate radioiodine, an attribute that can be used both for detection of thyroid cells and for treatment. Unfortunately, however, radioiodine uptake is not observed in all patients and a radioiodine scan requires that the patient be rendered hypothyroid for 4-6 wk. In the present study, we analyzed the utility of thallium-201 scanning and the usefulness of magnetic resonance imaging (MRI) in the detection of thyroid cancer. Nineteen patients with thyroid cancer had a total of 24 radioiodine scans, 33 thallium scans, and 10 MRI examinations. Of the 19 patients in the study, 17 had differentiated thyroid carcinoma. In these 17 cases, all paired studies were concordant for the presence (n = 7) or absence (n = 10) of disease. However, in one case (Patient 10), the {sup 201}Tl studies showed far more extensive disease than was observed on the {sup 131}I scan. Thyroid cancer was also detected on seven MRI studies. In summary, thallium and MRI scans are adjunctive techniques to radioiodine scanning that can either confirm the presence of neck bed activity, residual disease or metastatic cancer and may delineate tumor deposits not detected by radioiodine scanning. Thallium may be capable of detecting tumor deposits even while a patient remains euthyroid.

    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 implicate...

    A retrospective review of thirty patients with papillary carcinoma of the thyroid with metastatic or direct extension of their disease was undertaken. These thirty patients were treated by a standard surgical procedure and postoperative high dose orthoirradiation with an average twenty-one year follow-up period. Results of this treatment are compared with those of eighty similar patients treated by surgery alone. The primary treatment of papillary carcinoma of the thyroid remains surgical but with a consideration that irradiation may be of benefit in certain instances.

    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

    Objective To determine the expression of P53 and P21 (WAF1/CIP1) in thyroid carcinomas and its relationship with development and prognosis of the carcinoma. Methods 90 cases of thyroid tissues (60 thyroid carcinomas, 10 thyroid adenomas, 10 goitres and 10 normal thyroid tissues) were studied by SP immunohistochemical method. Results Positive immunoreactivity of P53 and P21(WAF1/CIP1) was found only in thyroid carcinomas. The positive rate of the P53 and P21 is 53.3% and 41.7% respectively. The positive-staining rates of P53 were higher in cases of undifferentiated carcinomas, positive metastasis lymph nodes or in stage Ⅲ, Ⅳ than those in the cases of well-differentiated, no metastasis lymph nodes, or in stage Ⅰ,Ⅱ. In addition, the positive-staining of P21(WAF1/CIP1) were lower in cases of undifferentiated carcinomas, positive metastasis lymph nodes or stage Ⅲ, Ⅳ than that in the cases of well-differentiated, no metastasis lymph nodes or in stage Ⅰ,Ⅱ. The P21 (WAF1/CIP1) expression rate in the P53 positive group was lower than that in the P53 negative group (P<0.05). Conclusion The expression of P21(WAF1/CIP1) protein in thyroid cancer is related to P53-depend pathway and P53-independent pathway, mainly the P53-depend pathway. Examination of expression of P53 and P21 (WAF1/ CIP1) proteins may be helpful to judge the thyroid cancers behavior and prognosis.

  19. Evaluation of the VE1 Antibody in Thyroid Cytology Using Papillary Thyroid Carcinoma Specimens

    2016-01-01

    Full Text Available 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.

    Metastases to the thyroid are uncommon [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.

    2015-01-01

    Full Text Available A 44-year-old female presented with a two-month history of a neck mass, sore throat, hoarseness, and intermittent dysphagia. Examination revealed a “woody” hard swelling arising from the right lobe of the thyroid. Clinically this was felt to be classical Riedel’s thyroiditis (RT. Thyroid ultrasound showed a diffusely enlarged, low echogenicity thyroid with a multinodular goitre. An abnormal nodule extending across the isthmus was noted. Following a nondiagnostic fine needle aspiration, an open core biopsy was performed. This showed dense sclerotic fibrosis punctuated by nodular mononuclear inflammatory cells, which obscured follicular epithelial cells consistent with a fibrosing thyroiditis (Riedel’s thyroiditis. A biopsy of pretracheal lymph nodes showed a sclerotic process throughout the lymph nodes and nests of epithelium bands with squamous differentiation obscured by a fibrous process. These findings raised the differential diagnosis of diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC with metastasis to lymph nodes. A total thyroidectomy and pretracheal lymph node dissection were performed. The final histological diagnosis was DSV-PTC. When managing a patient with presumed RT it is important to consider malignancy in the differential. DSV-PTC is one of the more aggressive forms of thyroid cancer but with early diagnosis and appropriate treatment patients may have excellent outcomes.

    Full Text Available Introduction: Papillary carcinoma is the most common malignant tumor of the thyroid gland, which is clinically manifested as painless and (impalpable node in the glandular parenchyma. The aim: Analysis of demographic features of the patients with papillary thyroid carcinoma, localization and histomorphology characteristics, as well as associated pathology. Materials and Methods: We analyzed the medical records of 38 patients, to whom pathohistological diagnosis of papillary thyroid carcinoma was given, in the period from January 2011 to December 2015, at the Center for Pathology and Histology, Clinical Center of Vojvodina, Novi Sad. Results: Pathohistologically, 38 papillary carcinoma of the thyroid gland were verified, where 71.05% were females. The average age of patients was 50 years. In our study, the average tumor size was 12.4 mm, while it was some larger in male patients (13.7 mm, compared to female (11.1 mm. Tumor node was more frequent in the right lobe (34.21%. In 34.21% of patients coexistence of the goiter was found, 18.42% had associated Hashimoto's thyroiditis, while 10.52% had associated adenoma of the thyroid gland. Conclusion: Papillary carcinoma is 2.5-3 times more frequent in females, usually in the second half of the 5th decade of life, while the males suffer at some later ages. The largest number of patients belong to stage T1, while the most frequent associated disease is goiter. Thyroidectomy with pathohistological TNM staging is imperative for continued adequate clinical treatment and monitoring of patients.

    The purpose of this study is to analyze the computed tomography (CT) features of follicular thyroid carcinoma (FTC) as compared to those of papillary thyroid carcinoma (PTC) to identify the characteristic imaging features of FTC. The following CT features were analyzed to compare FTCs (n = 17) and PTCs (n = 27): size, shape, margin, internal composition, calcification, enhancement homogeniety, extrathyroidal extension, lymph node (LN) metastasis and the density and degree of enhancement (qualitatively and quantitatively). There were no significant differences between the patients with FTCs and those with PTCs with respect to age and gender, and the internal composition, calcification and enhancement homogeneity of the tumor. However, the FTCs tend to show a larger size (32 mm vs. 15 mm: respectively, p < 0.001), a round to oval shape (52.9% vs. 14.8% respectively, p = 0.001), a well-defined smooth margin (58.8% vs. 14.8% respectively, p = 0.009), less extrathyroidal extension (11.8% vs. 51.9% respectively, p= 0.007) and less LN metastasis (0% vs. 29.6% respectively, p = 0.016) compared to that of the PTCs. Furthermore, the FTCs showed significantly stronger enhancement in the early phase (146.4{+-}42.4 vs. 98.5{+-}38.2 respectively, p < 0.001) and a greater decrement of the late enhancement (-44.6{+-}25.2 vs. -18.7{+-}27.9 respectively, p = 0.003) compared to that of the PTCs. FTCs had a tendency to be observed on neck CT as well-defined, smooth, round to oval nodules with strong early enhancement and a definite decrement of late enhancement as compared to the PTCs

    Full Text Available 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 Hόrthle cells. Our case highlights an unusual instance of MTC in concurrence with HT that can create a tricky situation for cytopathologists.

  6. Anaplastic transformation of metastatic papillary thyroid carcinoma at shoulder mimicking soft tissue sarcoma

    Full Text Available A 52-year-old woman presented with fracture upper end of the left humerus after trivial trauma and aspiration cytology from the lytic lesion in the upper humerus seen on X-ray revealed a metastatic papillary carcinoma from the thyroid. Total thyroidectomy confirmed the papillary carcinoma thyroid. Post-operatively, she was given radioactive iodine (I-131 ablation therapy for 8 years and was asymptomatic during this period; however, for the last 1 year, she has been complaining of swelling in the shoulder, which did not respond to palliative radiotherapy and rapidly increased in size. Disarticulation of the shoulder joint was performed, which showed anaplastic carcinoma on histopathological examination. Anaplastic transformation of papillary carcinoma at the metastatic sites is well documented in the literature and is rare. However, the same has not been reported at the shoulder and from India before. Although soft tissue sarcomas are most common at this site, however, the possibility of anaplastic transformation should be kept in the differential diagnosis of rapidly enlarging painful mass in a known case of metastatic thyroid carcinoma to prevent misdiagnosis.

    2015-01-01

    Objective:Differentiated thyroid carcinomas (DTCs) are classiifed into papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC). DTCs are analyzed as a single group in clinical studies that investigated the prognostic factors and prognosis of these malignancies. However, the biological behaviors of these carcinomas signiifcantly differ. In the present study, we aimed to detect differences in the outcomes between PTC and FTC in Mansoura University Hospital in Egypt. Methods:A total of 558 patients with histologically proven thyroid carcinomas from January 2003 to December 2012 were retrospectively enrolled. hTe clinical and pathological data of patients were reviewed. Results:Large primary tumor size, lymph node involvement, extrathyroid extension, and distant metastasis were signiifcant poor prognostic factors for overall survival (OS) in old PTC patients. Cox hazard analysis showed that the patient’s age, extra thyroid extension, and distant metastasis were the only independent prognostic factors. In FTC patients, only the distant metastasis and degree of tumor invasion were signiifcant poor prognostic factors in OS univariate analysis. However, these factors were nonsignificant in multivariate analysis. The 10-year OS rates were 97%and 89%for PTC and FTC, respectively (P=0.003). hTe 10-year disease-free survival (DFS) rates were 77.2%in PTC vs. 65%in FTC (P=0.179). Conclusion:hTe signiifcant prognostic factors vary between the two types of DTCs. hTerefore, PTC and FTC patients need to be analyzed and reported independently. PTC survival is widely and signiifcantly affected by age, extrathyroid extension, and distant metastasis. By contrast, these factors were nonsigniifcant in FTC, which showed poorer survival than PTC.

    Metastatic disease is the first clinical manifestation of differentiated thyroid carcinoma (DTC) in less than 5% of cases. Bone metastases as the first sign of DTC are associated with a poor prognosis, both for being resistant to treatment and for complications due to them. Spinal cord compression is a rare development in DTC, which may present late in the course of the disease. An initial presentation of DTC with a spinal cord compression is an extremely rare condition.

    2016-07-01

    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.

    2014-09-20

    Ectopic thyroid tissue of nasopharynx is an uncommon phenomenon and papillary thyroid carcinoma arising from the tissue is extremely rare. The authors report a rare case of 16-year-old girl with papillary thyroid carcinoma of nasopharynx. Clinicians were ever confused by adenoid hypertrophy and solved the diagnostic dilemma by adequate examinations. In the case, we mainly emphasize that surgeons should be aware of and actively consider such a possibility of ectopic papillary thyroid carcinoma of nasopharynx in children and adolescents with long-term nasal obstruction, even if thyroid carcinoma is a rare tumor.

    Aim: The aim of this study was to observe the findings of magnetic resonance spectroscopy of solitary thyroid nodules and its correlation with histopathology. Materials and methods: In this study, magnetic resonance spectroscopy was carried out on 26 patients having solitary thyroid nodules. Magnetic resonance spectroscopy (MRS) was performed on a 1.5 T super conductive system with gradient strength of 33 mTs. Fine needle aspiration cytology was done after MRS. All 26 patients underwent surgery either because of cytopathologically proven malignancy or because of cosmetic reasons. Findings of magnetic resonance spectroscopy were compared with histopathology of thyroid specimens. Results and conclusion: It was seen that presence or absence of choline peak correlates very well with presence or absence of malignant foci with in the nodule (sensitivity = 100%; specificity = 88.88%). These results indicate that magnetic resonance spectroscopy may prove to be an useful diagnostic modality for carcinoma thyroid.

    Environmental factors contributing to incidences of thyroid carcinoma are re-evaluated and emphasized in this study. Thyroid cancers appear to occur independent of endemic goiter, based on epidemiologic and histologic evidence. While environmental factors appear to be important, the specific etiologic agent has not yet been identified or suggested. The number of thyroid cancer incidences available from cancer registries are analyzed in an attempt to identify a specific environmental carcinogenic agent. The presence of active volcanoes that produce abundant lava is found to be the common denominator of Iceland and Hawaii, where the incidence of thyroid cancer is outstandingly high. Comparison with other areas with active volcanoes is made. The presence of a carcinogenic agent in the lava is postulated and its possible mode of action on humans through fish products is hypothesized.

    2013-01-01

    Full Text Available Tumors that metastasize to paranasal sinus (PNS are rare, with fewer than 200 cases reported worldwide. Of these, thyroid malignancies contribute 8%. We discuss here a patient aged 45 years with PNS mets from follicular variant of papillary carcinoma thyroid who had undergone surgery and radioiodine ablation. He presented with nasal obstruction and epistaxis 2 years after local treatment. CT scan of PNS showed a large heterogeneously enhancing mass lesion in PNS, which on further evaluation was found to be consistent with metastases from primary thyroid cancer. He was given palliative radiotherapy to the metastatic lesion. Patient was alive after eighteen months of radiotherapy but there was no response to radiotherapy on imaging. To conclude PNS metastases from thyroid cancer are rare. But it should be always kept in mind in symptomatic patients. Also, patients with PNS mets can have a long disease free survival after palliative radiotherapy.

    We determined the reasons for radioiodine thyroid remnant ablation, and the procedure's necessity based on postsurgical remnant size, in patients with putatively ''low-intermediate-risk'' differentiated thyroid carcinoma (DTC). We identified key clinicopathological, treatment and remnant characteristics, and factors associated with remnant size in 336 patients with pT1/2, M0 DTC ablated during the period September 2010 to October 2013 at one Cypriot or one Greek referral centre. Clinicopathological/treatment characteristics were compiled from charts. Experienced nuclear medicine physicians rated the numbers/intensities of uptake foci in the thyroid bed on postablation planar scintigrams using scales of 0-4 points and 0-3 points, respectively. The product of these scores was taken as the ''remnant score'' that ranged from 0 (no remnant) to 12 (multiple remnants, intense uptake). DTC was predominantly papillary. The median [25th-75th percentile] longest primary tumour diameter was 1.0 cm [0.7-1.5 cm]. Despite favourable histotypes and primary tumour classifications, patients often had preablation characteristics suggesting elevated or uncertain risk: 31.0 % of patients (104 of 336) had primary tumour multifocality, 22.0 % (74) had confirmed cervical lymph node metastases, 37.2 % (125) had unknown nodal status, and 38.1 % (128) had antithyroglobulin antibody seropositivity. The median [25th-75th percentile] remnant score was 4 [2-6]; 39.9 % of patients (134 of 336) had scores ≥6. For the entire cohort, T or N stages (r ≤ 0.174, P ≤ 0.05) correlated positively with the remnant score in a univariate Spearman analysis. The numbers of patients referred by the surgeon, cervical lymph nodes excised and metastatic nodes excised correlated negatively (r ≤ 0.243, P ≤ 0.038) with the remnant score, and the first two factors independently predicted the remnant score (P ≤ 0.037) in a multivariate analysis. Patients with

    To assess the risk of differentiated thyroid cancer (DTC) recurrence, DTC-related mortality and life expectancy in relation to the number of courses of {sup 131}I therapy (RIT) and cumulative {sup 131}I activities required to achieve complete remission (CR). The study was a database review of 1,229 patients with DTC, 333 without and 896 with CR (negative TSH-stimulated thyroglobulin and negative {sup 131}I diagnostic whole-body scintigraphy) after one or more courses of RIT. The median follow-up was 9.0 years (range 0.1 - 31.8 years) after CR. Recurrence rates at 5 years, 10 years and the end of follow-up were 1.0 ± 0.3 %, 4.0 ± 0.7 % and 6.2 ± 1.1 %, and DTC-related mortality was 0.1 ± 0.1 %, 0.5 ± 0.3 % and 3.4 ± 1.1 %, respectively. Recurrence rates also increased with an increasing number of RIT courses required (p = 0.001). DTC-related mortality increased from four RIT courses. In patients with CR after one RIT course, there were no differences in recurrence or DTC-related mortality rates between low-risk and high-risk patients. In patients requiring two RIT courses these rates remain elevated in high-risk patients. Recurrence and DTC-related mortality rates were only significantly elevated in those requiring a cumulative activity over 22.2 GBq (600 mCi) from multiple RIT courses for CR. Regardless of the number of RIT courses or activity needed, life expectancy was not significantly lowered. If more than one RIT course is needed to achieve CR, higher recurrence and DTC-related mortality rates are observed, especially in high-risk patients. Patients requiring >22.2 GBq {sup 131}I for CR should be followed in the same way as patients in whom CR is never reached as long-term mortality rates are similar. (orig.)

    2016-03-01

    Full Text Available The aim of this report is to present a rare case of papillary thyroid cancer metastasis to the kidney manifesting with obstructive nephropathy. A 68 year-old man was referred to ultrasound examination because of a multinodular goiter. Ultrasound guided fine needle aspiration biopsy (US-FNAB suggested follicular adenoma of the right thyroid lobe and a right lobectomy with isthmectomy was performed. Pathohistologic findings confirmed a follicular variant of papillary thyroid carcinoma and the patient underwent a total thyroidectomy followed by radioiodine ablation. A few years later, scintigraphy revealed radioiodine avid metastatic foci in the right kidney as well as an intramuscular lesion in the left thigh. At the same time, non-small cell lung cancer was diagnosed. Papillary thyroid carcinoma is the most common thyroid malignancy, but renal or muscular metastases are extremely rare in this type of cancer and can be found in poorly differentiated cancers, which should be clearly stated in the final pathohistologic report. In order to better the interpretation of these pathohistological findings and allow successful monitoring of these patients, close cooperation with pathologists and immunohistochemical profiling is suggested.

    2011-01-01

    Full Text Available Context: Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. Case Report: We report a case of a 41-year old man presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect. After magnetic resonance imaging (MRI a suspect diagnosis of meningioma was made. The patient underwent surgery where a soft mass with transverse sinus invasion was encountered; the tumour was successfully resected employing microsurgical techniques. Histological examination revealed a thyroid follicular neoplasm with positive staining for follicular carcinoma in immunohistochemical analysis. Postoperatively levels of thyroid hormones were normal. Treatment was planned for the thyroid gland, patient receiving 6 courses of chemotherapy including paclitaxel. Conclusions: The present case emphasizes that although they are uncommon, dural metastasis can be mistaken for meningiomas. The definitive diagnosis of a meningioma should be established only after the histopathological analysis. Thyroid follicular carcinoma should be included in the differential diagnosis in cases of extrinsic tumoral lesions.

    Full Text Available An 18-year-old, male, castrated, captive-born leopard (Panthera pardus presented to Colorado State University’s Veterinary Teaching Hospital with a two-week history of regurgitation. Thoracic radiographs and ultrasound revealed a well-differentiated cranioventral mediastinal mass measuring 7.5 × 10 × 5.5 cm, impinging the esophagus. A sternotomy followed by mass excision was performed. The mass was diagnosed as an ectopic thyroid carcinoma. The leopard recovered from surgery with minimal complications and returned to near-normal activity levels for just under 6 months before rapidly declining. He had an acute onset of severe dyspnea and lethargy and was euthanized. On postmortem examination the tumor was found to involve the lung, liver, thyroid, parietal pleura, bronchial lymph nodes, and the internal intercostal muscles. This case report describes the history, diagnosis, surgical treatment, postoperative care, and recovery as well as the eventual decline, euthanasia, and necropsy of a leopard with thyroid carcinoma. When compared to thyroid carcinomas of domestic animals, the leopard’s disease process more closely resembles the disease process seen in domestic canines compared to domestic cats.

    Full Text Available We report an aggressive papillary thyroid carcinoma (PTC with focal undifferentiated component in a 32-year-old female. She had limited disease confined within the thyroid gland at diagnosis. Within 12 months of thyroidectomy and radioiodine ablation, thyroglobulin (Tg levels were elevated. Second radioiodine ablative dose was given, however, stimulated Tg levels showed an upward trend with negative iodine scan within 12 months. An 18F fludeoxyglucose-avid solitary pulmonary nodule that was detected on positron emission tomography/computed tomography scan was resected followed by empiric radioiodine therapy. Within the next 10 months she developed multifocal bone metastases. The multifocal disease was rendered inoperable and treated with external beam radiation. The patient is on follow-up, and the Tg level continues to rise with local disease progression. In a small percentage of patients, PTC behaves as a very aggressive disease despite treatment. Focally undifferentiated thyroid carcinoma is an expression of the extreme end of the spectrum of differentiated thyroid carcinoma.

    Differentiated thyroid carcinoma (DTC) is a common malignancy. The general treatments are thyroidec-tomy 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 stil controversial. Here we present a case of folicular thyroid carcinoma with the 6th cervical vertebra body metastasis successfuly treated by total thyroidectomy, cervical corpectomy, and internal fixation, folowed by hormone replacement therapy and radioiodine therapy. Eleven additional patients diagnosed as thyroid carcinoma with bone metastasis colected 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 lo-bectomy 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 folow-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 multidisci-plinary cooperation. Surgical resection is stil the first choice for cure, while the combined one-stage operation on the primary and metastatic sites folowed by hormone replacement therapy and radioiodine therapy is an applicable treatment.

    The author describes the retrospective data acquisition and evaluation on the characterization and prognosis for 776 patients (average age 40:1 years) with differentiated thyroid carcinomas in the Klinik und Poliklinik fuer Nuklearmedizin der Universitaet zu Koeln in the period from 1990 to 2005. The methodology includes patient-relevant data, examination data, imaging techniques and biochemical tests. Clinically important differences were found for papillary and follicular thyroid carcinoma. Further differences concern the localization of metastases. The author discusses the prognostic significance of the primary tumor radius in comparison with the so-called TNM classification for papillary and follicular thyroid carcinomas. It is concluded that the new version of the TNM classification offers only slight advantages with respect to the former version. It was also shown that the primary tumor size is adequate for prognostic estimations.

    Application of distinct technologies of cancer genome analysis has provided important information for the molecular characterization of several human neoplasia, including follicular cell-derived thyroid carcinoma. Among them, comparative genomic hybridization (CGH)-based procedures have been extensively applied to evaluate genomic imbalances present in these tumours, obtaining data leading to an increase in the understanding of their complexity and diversity. In this review, after a brief overview of the most commonly used CGH-based technichs, we will describe the major results deriving from the most influential studies in the literature which used this approach to investigate the genomic aberrations of thyroid cancer cells. In most studies a small number of patients have been analyzed. Deletions and duplications at different chromosomal regions were detected in all investigated cohorts. A higher number of genomic imbalances has been detected in anaplastic or poorly differentiated thyroid carcinomas compared to well differentiated ones. Limitations in the interpretation of the results, as well the potential impact in the clinical practice are discussed. Though a quite heterogeneous picture arises from results so far available, CGH array, combined with other methodologies as well as an accurate clinical management, may offer novel opportunities for a better stratification of thyroid cancer patients.

    A case of metastasis to the sella turcica from a follicular adenocarcinoma of the thyroid gland is presented. Metastasis to this site is rare and review of the literature reveals only 12 cases of metastatic thyroid carcinoma involving the sella turcica and pituitary gland. The optimal treatment strategy is still to be determined. A 43-year-old woman presented with headache, nausea, visual impairment and galactorrhea. An MRI scan of the cranium revealed an enhancing destructive sellar lesion. The patient underwent transsphenoidal removal of the lesion to alleviate visual loss. The histological features of the sellar tumor were identical to those of a follicular adenocarcinoma partially removed from the thyroid gland 22 months earlier. Total thyroidectomy followed by three courses of iodine-131 ablation enhanced with synthetic thyrotropin and thyroid hormone suppression therapy was instituted. The post-operative course was satisfactory with improved vision and ceased galactorrhea. This case was successfully treated with a combination of surgical removal, iodine-131 ablation and hormone suppression therapy, which resulted in disease control duration of four years. Sella turcica metastases of thyroid carcinoma are exceedingly rare and currently there are no established therapeutic guidelines.

    We studied the clonality of medullary thyroid carcinomas (MTC) from 16 female patients by determining X chromosome inactivation by polymerase chain reaction (PCR) amplification of a CAG repeat in exon 1 of the human androgen-receptor gene. One patient with sporadic medullary thyroid carcinoma (MTC) was homozygous for this microsatellite and was not considered for the assessment of clonality. Sixteen tumor samples from the informative 15 patients were studied: 11 were from sporadic cases and 5 were from familial cases (3 cases of multiple endocrine neoplasia type 2A [MEN 2A]; 1 case of familial medullary thyroid carcinoma [FMTC]). Fourteen tumor samples (10/11 sporadic, 3/4 MEN 2A and 1/1 FMTC) were clearly monoclonal with allelic cleavage ratios between 2.5 and 49.1. Sixty-four percent of these cases (9/14) had the preferential amplification of the shorter allele while 36 percent (5/14) had the preferential amplification of the longer allele. Two frozen tumor samples (1 sporadic and 1 MEN 2A) were polyclonal. However, the corresponding tumor embedded in paraffin from the sporadic case was monoclonal. The other polyclonal tumor was found in the right thyroid lobe of a patient with MEN 2A who had a monoclonal tumor in the left lobe. Our results clearly demonstrate that MTC have a monoclonal origin in the majority of the cases.

    Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited disorder, the result of a germ line mutation in the adenomatous polyposis coli (APC) gene. FAP can be associated with various extracolonic lesions, including thyroid cancer, which frequently occurs in women. We report the case of a 36-year-old woman diagnosed as having FAP with multiple metachronous thyroid papillary carcinomas. She underwent left thyroidectomy at the age of 19 years without a diagnosis of FAP. Multiple polyps in her stomach were detected by medical examination and more than 100 polyps in the colon were found by colonoscopy. She was referred to our hospital after a diagnosis of non-profuse FAP. Multiple tumors with a maximum diameter of 10mm were detected in the right lobe of the thyroid gland during the preoperative examination. Papillary carcinoma was suspected based on fine-needle aspiration cytology. We performed a right thyroidectomy after prophylactic colectomy. Pathological findings revealed a cribriform-morula variant of papillary thyroid carcinoma. The patient remains well after 2 year 6 months with no recurrence.

    Warthin-like Papillary thyroid carcinoma (WPTC) is a rare variant of papillary carcinoma of thyroid, PTC which derives its name by closely resembling Warthin's tumor of salivary gland. Hallmark histological feature of this variant is papillary folding lined by oncocytic neoplastic cells with clear nuclei and nuclear pseudoinclusions, accompanied by prominent lymphocytic infiltrate in the papillary stalks. It is thought to be one of those differentiated thyroid cancers with favorable prognosis. We report a case of Graves' disease with a cold nodule harboring WPTC with initial presentation of lymph nodal metastases. It is important to identify this peculiar variant of PTC as 5 to 10% of them undergo dedifferentiation and 30% have the lymph nodal metastases and extra thyroidal extension.

    Differentiated thyroid cancer (DTC) is markedly more common in women than men, the highest female-to-male ratio being recorded during the reproductive period. This evidence has led to the suggestion that female hormonal and reproductive factors may account for the observed DTC gender disparity. This review focuses on current evidence on the risk of DTC in conjunction with major female reproductive factors, including the impact of pregnancy on DTC occurrence and progression/recurrence. Overall, studies exploring the link between the risk of DTC and menstrual and menopausal factors, oral contraceptives and/or hormone replacement therapy, showed these associations, if any, to be generally weak. Nonetheless, there is some evidence that higher levels of exposure to estrogens during reproductive years may confer an increased risk of DTC. As far as pregnancy is concerned, it is unclear whether a potential association between parity and risk of DTC actually exists, and whether it is enhanced in the short-term following delivery. A possible role for pregnancy-related factors in DTC progression has been recently suggested by some reports, the results of which are consistent with a worse outcome in the short-term of women diagnosed with DTC during gestation compared to non-pregnant control patients. Also, some progression of disease has been described in women with structural evidence of disease prior to pregnancy. However, there seems to be no impact from pregnancy in DTC-related death or overall survival. Several in vitro and animal studies have evaluated the influence of estrogens (E) and estrogen receptors (ERs) on thyroid cell proliferation. Presently available data are indicative of a role of E and ERs in thyroid cancer growth, although considerable discrepancies in respect to ER expression patterns in thyroid cancer tissues actually exist.

    Full Text Available Abstract Introduction The distant metastases from differentiated thyroid carcinomas are often untreatable. In particular, bone metastasis is significantly related to poor prognosis since radioactive iodine therapy is generally less effective. Therefore, surgical resection is considered one of the treatments for patients with bone metastases. We report chest wall resection and reconstruction using titanium micromesh covered with polypropylene mesh (Marlex mesh for metastatic rib bones as a result of follicular thyroid carcinoma. Case presentation A 51-year-old man was referred to our institution with a painful chest wall tumor. He presented with a 15 × 10 cm bony swelling on the left chest wall and multiple small lung nodules from follicular thyroid carcinoma. Completion total thyroidectomy, chest wall resection and reconstruction using titanium micromesh covered with Marlex mesh were performed. There were no critical complications associated with surgical treatments and tumor pain disappeared during the postoperative period. Then, he received radioactive iodine therapy and the uptake of radioactive iodine was well observed in bilateral lung fields. Conclusion Reconstruction using titanium micromesh covered with Marlex mesh is possible for repairing the wide chest wall resection required for thyroid carcinoma metastasis. This technique would help to enhance treatment efficacy in the combination therapy of radioactive iodine and surgery in patients with large thyroid carcinoma metastasis in the chest wall.

    The technique of selective embolization has been applied for years in the treatment of vascular anomalies, severe hemorrhage and benign or malignant tumors, notably vertebral metastases of renal cell carcinoma. Because this technique is relatively easy to perform and offers immediate relief of symptoms, it is an attractive option for patients with vertebral metastases of thyroid carcinoma with signs of spinal cord compression. In these patients, other treatment modalities like radioactive iodine, external irradiation, or surgery are more cumbersome or less effective in the short term. We describe four patients with metastasized follicular thyroid carcinoma, presenting with neurological symptoms due to vertebral metastases. All patients had undergone total thyroidectomy, ranging from 1 month to 4 yr before embolization. Embolization was combined with iodine-131 therapy when appropriate. Selective catheterization of the arteries feeding the metastases was performed, followed by infusion of polyvinyl alcohol particles (Ivalon). The procedure was technically successful in all patients without adverse effects. In the patients described, embolization resulted in rapid resolution of neurological symptoms, sometimes within hours. The therapeutic effect lasted from months to years. We conclude that embolization of vertebral metastases of follicular thyroid carcinoma is an attractive palliative therapeutic option that may offer rapid relief of symptoms.

    Objective To evaluate the clinical value of radioiodine - 131 SPECT/CT image in patients with differentiated thyroid carcinoma. Methods Two hundred and eight cases of both whole body scans and SPECT/CT images were studied, which performed in 5 ~ 7 days after receiv-ing 3.7~11.1 GBq of radioiodine- 131 by oral intake for radioablation of thyroid remnants or recur-rent and metastatic foci after a thyroidectomy in one hundred forty - two patients with differentiated thyroid carcinoma. Results The truth - positive, false - positive, false - negative and truth - nega-tive of 131I - SPECT/CT images for detecting DTC recurrent and metastatic foci were 427, 2, 14 and 208 respectively, but those of 131I- WBS were 245, 14, 48 and 155. The sensitivity and accu-racy of 131I - SPECT/CT images in this study for detecting DTC recurrent and metastatic foci were 96.8% and 97.5%, which were significantly higher than 131I - WBS(P<0. 001, P<0.001), whereas those of 131I - WBS were 83.6 % and 86.5 % respectively. The specificity of 131I - SPECT/ CT images for detecting recurrent and metastatic foci in DTC patients was higher than 131I - WBS (0. 01differentiated thyroid carcinoma,DTC)患者131I - SPECT/CT显像的临床价值.方法 142例DTC患者甲状腺全切或次全切除术后行放射性131I

    Full Text Available MicroRNAs (miRNAs are small non-coding RNAs approximately 22 nucleotides in length that function as regulators of gene expression. Dysregulation of miRNAs has been associated with initiation and progression of oncogenesis in humans. Our group has previously described a unique miRNA expression signature, including the MIR200 family member MIR141, which can differentiate papillary thyroid cancer (PTC cell lines from a control thyroid cell line. An investigation into the expression of MIR141 in a series of archival thyroid malignancies (n=140; classic PTC, follicular variant PTC, follicular thyroid carcinoma (FTC, Hashimoto thyroiditis (HT, or control thyrocytes was performed. Each cohort had a minimum of 20 validated samples surgically excised within the period 1980 - 2009. A subset of the HT and cPTC cohorts (n=3 were also analysed for expression of TGFβR1, a key member of the TGFβ pathway and known target of MIR141. Laser capture microdissection was used to specifically dissect target cells from formalin-fixed paraffin-embedded archival tissue. Thyrocyte- and lymphocyte-specific markers (TSHR and LSP1 respectively confirmed the integrity of cell populations in the HT cohort. RNA was extracted and quantitative RT-PCR was performed using comparative CT (ΔΔCT analysis. Statistically significant (p<0.05 differential expression profiles of MIR141 were found between tissue types. HT samples displayed significant downregulation of MIR141 compared to both classic PTC and control thyrocytes. Furthermore, TGFβR1 expression was detected in cPTC samples but not in HT thyrocytes. It is postulated that the down-regulation of this miRNA is due, at least in part, to its involvement in regulating the TGFβ pathway. This pathway is exquisitely involved in T-cell autoimmunity and has previously been linked with HT. In conclusion, HT epithelium can be distinguished from cPTC epithelium and control epithelium based on the relative expression of MIR141.

    Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis. Surprisingly, transthoracic biopsy and histopathology revealed metastasis from follicular carcinoma of thyroid. This prompted us for a retrograde evaluation for a primary thyroid malignancy for which an ultrasound and contrast enhanced computed tomography (CECT) of the neck was done which confirmed the presence of a solitary thyroid nodule. Ultrasonography-guided fine-needle aspiration cytology of the nodule revealed follicular carcinoma of thyroid. Histopathological evaluation subsequent to total thyroidectomy revealed follicular carcinoma thyroid, further confirming the diagnosis. The patient was then referred to Department of Nuclear Medicine and Radiotherapy for radionuclide ablation and chemotherapy. We chose to report this case because of its rare presentation as a large intrathoracic mass and the retrograde diagnosis of follicular carcinoma of thyroid. To the best of our knowledge, this is the first report of such a rare case.

    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.

    Bone metastases is a well described event in the natural history of thyroid cancers and has the potential to severely impact the quality of life by causing pain, fractures and spinal cord compression. Follicular thyroid carcinomas have a greater propensity for distal metastasis than papillary and anaplastic thyroid carcinomas. The most common sites of skeletal metastasis among thyroid cancer patients are femur followed by humerus, pelvis, radius, and scapula. Clavicle metastasis at initial presentation is exceedingly rare. Although many studies have examined the various prognostic factors for patients with bony metastases from thyroid cancers, very few have actually evaluated the effects of surgical management. We present an unusual case of metastatic papillary carcinoma thyroid presenting with clavicle metastasis and review the role of surgical management of bone metastases. Clavicular resection as a part of the management of metastatic papillary carcinoma thyroid has, to the best of our knowledge never been reported before.

    A 37-year-old male case was admitted with goiter. Ultrasonography of thyroid showed a 5 cm cystic nodule in the left lobe with a 1.5 cm solid component. Fine needle aspiration biopsy revealed atypia of undetermined significance or follicular lesion. The patient was operated on. The pathological diagnosis was reported as papillary thyroid carcinoma. The immunohistochemical examination showed multiple foci of Langerhans cell histiocytosis involving both lobes. The patient died due to cardiac arrest with respiratory causes in the early postoperative period. Langerhans cell histiocytosis is a rare primary condition which involves abnormal clonal proliferation of Langerhans cells in various tissues and organs. Thyroid involvement is infrequently seen. Although the etiology is unknown, genetic components may be linked to the disease. It is also associated with a family history of thyroid disease. Papillary thyroid carcinoma is the most common malignant epithelial tumor of the thyroid gland. Langerhans cell histiocytosis presenting with papillary thyroid carcinoma is rare. The privilege of our case is langerhans cell histiocytosis of the thyroid with multiple cervical lymph node involvement accompanying cervical lymph node metastatic thyroid papillary carcinoma.

    Elevated levels of D: -2-hydroxyglutarate (D: -2-HG) occur in gliomas and myeloid leukemias associated with mutations of IDH1 and IDH2. L: -2-Hydroxyglutaric aciduria, an inherited metabolic disorder, predisposes to brain tumors. Therefore, we asked whether sporadic cancers, without IDH1 or IDH2 hot-spot mutations, show elevated 2-hydroxyglutarate levels. We retrieved 15 pairs of frozen papillary thyroid carcinoma (PTC) and adjacent non-neoplastic thyroid, and 14 pairs of hyperplastic nodule (HN) and adjacent non-hyperplastic thyroid. In all lesions, exon 4 sequencing confirmed the absence of known mutations of IDH1 and IDH2. We measured 2-hydroxyglutarate by liquid chromatography-tandem mass spectrometry. Compared to normal thyroid, PTCs had significantly higher D: -2-HG and L: -2-hydroxyglutarate (L: -2-HG) levels, and compared to HNs, PTCs had significantly higher D: -2-HG levels. D: -2-HG/L: -2-HG levels were not significantly different between HNs and normal thyroid. Further studies should clarify if elevated 2-hydroxyglutarate in PTC may be useful as cancer biomarker and evaluate the role of 2-hydroxyglutarate in cancer biology.

    Objective To study the clinicopathologic features, immunophenotypes and differential diagnosis of thyroid carcinoma showing thymus-like differentiation (CASTLE). Methods The clinical and pathologic features of 8 cases of CASTLE were reviewed. Immunohistochemical study was performed using a panel of antibodies. ln-situ hybridization for Epstein-Barr virus-encoded RNA (EBER) was also carried out.Results There were altogether 4 males and 4 females. The age of the patients ranged from 25 to 57 years (mean =48.8 years). All of them presented with painless mass at the anterior neck. Two patients also complained of hoarseness of voice. On CT scan, the tumor had a low density with contrast enhancement.Seven cases were located in the mid to lower pole and the remaining one in the upper pole of thyroid gland.Four cases were relatively circumscribed. The other 4 cases showed evidence of extrathyroidal invasion.Grossly, the tumor had a nodular or lobulated appearance and was gray-white in color, with a mean diameter of 4. 3 cm. Microscopically, the tumor was infiltrative and consisted of islands, nests or lobules of epithelial cells separated by thick fibrous septa. The fibrous stroma showed various degree of lymphoplasmacytic infiltration, resulting in a prominent lymphoepithelioma-like pattern in 3 cases. Two cases showed squamoid differentiation, mimicking thymic Hassall corpuscles. Immunohistochemically, the tumor was consistently positive for cytokeratins, CD5, bcl-2, p63 and CD117. CEA was variably expressed. The staining for thyroglobin and TFl was negative. There was no labeling for EBER in all the cases. Two patients experienced local recurrence at 22 months and 12 years after surgery, respectively. They were treated with re-resection. All patients remained well on follow up. The duration of follow up ranged from 4 to 55 months.Conclusions CASTLE is a low-grade thyroid carcinoma with the morphologic features and immunophenotypes overlapping with those of thymic

    The macrofollicular variant of papillary thyroid carcinoma is a rare subtype of the follicular variant of papillary thyroid carcinoma and is usually characterized by an indolent clinical course. The tumors are prone to be misdiagnosed as benign due to their macrofollicular architecture and bland cytologic features. We report a rare case of the macrofollicular variant of papillary thyroid carcinoma with extensive lymph node metastases. The patient was a 48-year-old female with a right thyroid nodule and multiple enlarged lymph nodes in the right neck. It was not possible to make a definitive diagnosis of malignancy on fine-needle aspiration cytology and intraoperative frozen section. She underwent total thyroidectomy with right modified radical neck dissection. The surgical specimen showed a 2.5 × 1.5 × 10 cm, well-circumscribed macrofollicular variant of papillary thyroid carcinoma in the right lobe and multiple central and right lateral neck lymph node metastases. Molecular testing for BRAF, NRAS, HRAS, and KRAS was all negative. We then reviewed the demographic and clinicopathologic characteristics of 71 patients with the macrofollicular variant of papillary thyroid carcinoma. The cytologic or histopathologic diagnosis of macrofollicular variant of papillary thyroid carcinoma can be difficult. Extensive lymph node metastases caused by the macrofollicular variant of papillary thyroid carcinoma may occur even in the absence of capsular or lymphovascular invasion. This review will help to better understand the nature of the macrofollicular variant of papillary thyroid carcinoma.

    Full Text Available Tuberculous (TB lymphadenitis can mimic cervical node metastasis from papillary thyroid carcinoma (PTC since the distribution and appearance of affected lymph nodes are similar. We present the case of an asymptomatic 50-year-old Filipino who sought consult for a gradually enlarging anterior neck mass and a single palpable cervical lymph node. Preoperative workup suggested a thyroid malignancy with nodal metastasis. He underwent total thyroidectomy with node dissection where histopathology confirmed follicular variant- (FV- PTC. Lymph node examination, however, revealed TB lymphadenitis, and the patient was given standard antimycobacterial therapy. This is the first documented case in Southeast Asia, a high TB burden region. This is also the first report involving FV-PTC, which has features between those of conventional PTC and follicular thyroid carcinoma. The case suggests that, in endemic areas, TB should be a differential in the etiology of cervical lymphadenopathy in PTC patients. In developed countries, this differential diagnosis is also valuable because of the increasing incidence of HIV and TB coinfection. Proper preoperative evaluation is important and needs to be highlighted in the formulation of local guidelines.

    Full Text Available The majority of thyroid cancers arise from the follicular cells of the thyroid gland, which yield a wide variety of distinct morphotypes, ranging from relatively indolent lesions to the most malignant forms of cancer known. The remaining primary thyroid cancers arise from C cells within the gland and result primarily from mutations of the RET protooncogene, germ line mutations of which give rise to the various forms of multiple endocrine neoplasia. The most common of the follicular cell-derived cancers are papillary carcinomas, (PTC, followed by follicular carcinomas (FTC and its Hurthle cell variant (HCC and finally anaplastic carcinomas (ATC. The pathogenesis of many thyroid cancers, of both PTC and FTC morphotype, involves chromosomal translocations. Rearrangements of the RET protoconcogene are known to be involved in the pathogenesis of ca. 50% of PTC. A similar proportion of FTC have been associated with a t(2;3(q13;p25 translocation, fusing the thyroid-specific transcription factor PAX8 with the peroxisome proliferator-activated receptor gamma (PPARγ nuclear receptor, a ubiquitously expressed transcription factor. These rearrangements have analogy with translocations in erythropoetic cells, which form the only other known group of human malignancies that are largely the result of chromosomal translocation events. In this review we compare and contrast the oncogenic properties of thyroid and erythroid chromosomal transformations and speculate on mechanisms leading to their formation.

    To evaluate the significance of the extrathyroid extension (ETE) of papillary thyroid carcinoma at the time of diagnosis and the prognostic variables of patients, we retrospectively reviewed 1,013 thyroid cancer patients. Of the 741 papillary thyroid cancer patients, 466 (62.9%) were categorized in clinical stage I and 114 (15.4%) were categorized in clinical stage III. Of the 114 patients in clinical stage III, 81 were female (mean age 44.4{+-}15.7 years) and 33 were male (mean age 46.9{+-}18.1 years). Of the clinical stage III patients, 104 patients received post-operative radioactive iodide ({sup 131}I) therapy while 22 patients received external radiotherapy in the neck and upper mediastinum area post-operatively. In the study, age, gender, {sup 131}I accumulated dose, post-operative serum thyroglobulin (Tg) levels, and survival rate were demonstrated to be statistically significant in the groups with no recurrence and recurrence after treatment. The average follow-up period of these patients was 6.0 years. During this follow-up period, 11 patients expired. Eight died of thyroid cancer (7.0%) and 3 died of intercurrent diseases including asthma, renal cell carcinoma and propranolol overdose. Four of the 8 patients (50%) died of airway obstruction due to cancer cell invasion. Another 4 died of distant metastases, including 2 patients with skull metastases and brain invasion. The 5- and 10-year survival rates were 0.981 and 0.956 in clinical stage I and 0.923 and 0.843 in clinical stage III, respectively. In conclusion, the survival rate of the ETE of papillary thyroid cancer was lower when compared with stage I, especially in older male patients with higher post-operative serum Tg levels. (author)

    Full Text Available Abstract Introduction Papillary thyroid carcinoma and medullary thyroid carcinoma are two different thyroid neoplasia. The simultaneous occurrence of medullary thyroid carcinoma and papillary thyroid carcinoma as a collison tumor with metastases from both lesions in the regional lymph nodes is a rare phenomenon. Case presentation A 32-year-old Iranian man presented with a fixed anterior neck mass. Ultrasonography revealed two separate thyroid nodules as well as a suspicious neck mass that appeared to be a metastatic lesion. The results of thyroid function tests were normal, but the preoperative calcitonin serum value was elevated. Our patient underwent a total thyroidectomy with neck exploration. Two separate and ill-defined solid lesions grossly in the right lobe were noticed. Histological and immunohistochemical studies of these lesions suggested the presence of medullary thyroid carcinoma and papillary thyroid carcinoma. The lymph nodes isolated from a neck dissection specimen showed metastases from both lesions. Conclusions The concomitant occurrence of papillary thyroid carcinoma and medullary thyroid carcinoma and the exact diagnosis of this uncommon event are important. The treatment strategy should be reconsidered in such cases, and genetic screening to exclude multiple endocrine neoplasia 2 syndromes should be performed. For papillary thyroid carcinoma, radioiodine therapy and thyroid-stimulating hormone suppressive therapy are performed. However, the treatment of medullary thyroid carcinoma is mostly radical surgery with no effective adjuvant therapy.

    Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable.

    Objectives. Invasion of differentiated thyroid cancer (DTC) into surrounding structures can lead to morbid procedures such as laryngectomy and tracheal resection. In these patients, there is a potential role for neoadjuvant therapy. Methods. We identified three studies involving the treatment of DTC with neoadjuvant chemotherapy: two from Slovenia and one from Japan. Results. These studies demonstrate that in selected situations, neoadjuvant chemotherapy can have a good response and allow for a more complete surgical resection, the treatment of DTC. Additionally, the SELECT trial shows that the targeted therapy lenvatinib is effective in the treatment of DTC and could be useful as neoadjuvant therapy for this disease due to its short time to response. Pazopanib has also demonstrated promise in phase II data. Conclusions. Thus, chemotherapy in the neoadjuvant setting could possibly be useful for managing advanced DTC. Additionally, some of the new tyrosine kinase inhibitors (TKIs) hold promise for use in the neoadjuvant setting in DTC.

    Purpose: In patients with differentiated thyroid carcinoma, the correlation between the value of thyroglobulin and the positivity of F.D.G.-PET remains controversial. We looked at whether the immunohistochemical criteria of the original tumor could be predictive of a positive PET in cases of tumor recurrence. Conclusions: on a larger series, we have not confirmed the results of Hooft (JCEM 2005). This study did not reveal immunohistochemical marker, present in the original tumor, which would be predictive of a positive PET-F.D.G. in the search for a recurrence. The study of NIS and GLUT1 expression is underway. (N.C.)

    Full Text Available 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.

    The objective of this study, in addition to confirming that therapy with {sup 131}I causes oxidative stress, was to evaluate the effect of supplementation with vitamins C and E and selenium on this phenomenon by measuring plasma 8-epi-PGF2α, a marker of lipid peroxidation. Subjects and methods: Forty patients with thyroid cancer submitted to thyroidectomy, who received 3.7 GBq {sup 131}I after levothyroxine withdrawal, were selected; 20 patients did not receive (control group) and 20 patients received (intervention group) daily supplementation consisting of 2000 mg vitamin C, 1000 mg vitamin E and 400 μg selenium for 21 days before {sup 131}I. Plasma 8-epi-PGF2α was measured immediately before and 2 and 7 days after {sup 131}I. Results: A significant increase in plasma 8-epi-PGF2α after {sup 131}I was observed in the two groups. The concentrations of 8-epi-PGF2α were significantly higher in the control group before and 2 and 7 days after {sup 131}I. The percentage of patients with elevated 8-epi-PGF2α was also significantly higher in the control group before and after {sup 131}I. Furthermore, the increase (percent) in 8-epi-PGF2α was significantly greater in the control group (average of 112.3% versus 56.3%). Only two patients (10%) reported side effects during supplementation. Conclusions: Ablation with {sup 131}I causes oxidative stress which can be minimized by the use of antioxidants. (author)

    Full Text Available Follicular thyroid adenoma and carcinoma are very common. Benign and malignant lesions are usually indistinguishable from cytology alone and often require confirmatory resection. The spread of follicular carcinoma is usually hematogenous and is treated with surgery and adjuvant radioactive iodine. Very rarely, metastases occur in the mediastinum. Patients usually present with severe compressive symptoms. With proper treatment and follow-up, the prognosis for these type of thyroid malignancies is excellent. In the case presented here, our patient presented to the Universiti Kebangsaan Malaysia Medical Center with a progressively enlarging anterior neck swelling. The swelling had started 10 years before his presentation. We diagnosed him with an advanced thyroid malignancy with bulky mediastinal metastases. After extensive investigations and counseling, we chose to treat the patient with tumor excision and mediastinal metastases resection. Typically, mediastinal resection involves the removal of the sternum and use of an acrylic implant to recreate the sternum. In this case, the sternum and ribs were removed with subsequent myocutaneous flap coverage for the wound defect. Our experience represents an alternative treatment option in cases where implant use is unsuitable.

    Well-differentiated follicular thyroid carcinomas (FTCs) usually act indolently, while aggressively acting tumors are difficult to detect early enough. Estrogen receptors (ERs) have prognostic significance in many cancers. Thyroid diseases, including neoplasms, are associated with the female sex. The prognostic significance of ERs in FTCs has not been reported previously. We studied the role of ERα and ERβ in 83 cases of follicular thyroid adenoma (FTA) and 43 FTC cases, including seven cases of poorly differentiated FTC, obtained from the Department of Surgery, Helsinki University Central Hospital between 1990 and 2009. Patient follow-up was conducted until March 2011. Expression of ERα, ERβ, and MIB-1/Ki-67 was investigated by immunohistochemistry and correlated with clinicopathological characteristics, including survival. Two major observations were apparent. First, ERβ expression was significantly higher in FTA than in FTC, and it was a stronger differential diagnostic marker than MIB-1/Ki-67. Second, low ERβ expression correlated with poor survival in FTC. All cancer-specific deaths due to FTC were among low ERβ-score patients. ERβ is a differential marker for malignancy and could thus be used as a preoperative tool. FTC patients with a low ERβ score need more thorough follow-up and may benefit from more aggressive treatment.

    Whether or not autoimmune thyroid disease influences the progression of differentiated thyroid cancer (DTC) remains controversial. Findings of previous studies are influenced by lead time bias and/or procedure bias selection. These biases can be reduced by studying a single-institution patient population that underwent a similar extent of surgical resection. From a cohort of 660 patients with DTC who underwent thyroidectomy, we retrospectively studied 357 patients who underwent total thyroidectomy and central compartment node dissection (CCND) for DTC between 2003 and 2013. Forty-one percent (140/345) of study patients had lymphocytic thyroiditis (LT), and 30% (91/301) had serum positive for thyroglobulin antibody (TgAb). LT was reported in 78% of the TgAb-positive cases. Sixty percent (213/357) of cases had metastatic thyroid carcinoma in 1 or more neck lymph nodes (55% [198/357] central compartment, and 22% [77/356] lateral compartment). Patients with LT had fewer metastatic cervical lymph nodes than those with no LT (2.7 ± 4.7 vs 3.5 ± 4.8, respectively, P = .0285). Patients with positive TgAb and thyroiditis had a larger number of benign cervical lymph nodes removed than those with negative TgAb or no LT. No significant difference was observed in age, tumor size, multifocality, extrathyroidal extension, vascular invasion, or frequency of cervical lymph node metastasis between TgAb-negative and -positive cases or between cases with and without LT. Lymphocytic thyroiditis is associated with fewer central neck compartment metastatic lymph nodes and a larger number of excised reactive benign cervical lymph nodes. Whether this association indicates a protective role of thyroid autoimmunity in lymph node spreading remains unclear. CCND = central compartment node dissection DTC = differentiated thyroid cancer HT = Hashimoto thyroiditis LT = lymphocytic thyroiditis TgAb = thyroglobulin antibody TPO = thyroid peroxidase.

    Full Text Available A high prevalence of thyroid papillary cancer was reported in hepatitis-C-virus (HCV positive patients. However, the mechanistic role of hepatic-fibrosis in thyroid malignancy progressions is still unclear.We aimed to study the immune-modulatory interactions between thyroid papillary carcinoma and hepatic-fibrosis.Hepatic-fibrosis was induced in nude-nu-male mice by intra-peritoneal administration of carbon-tetrachloride. To induce thyroid-tumor, a thyroid papillary carcinoma cell line (NPA was injected subcutaneously in the backs. Fibrotic profile was estimated by α-smooth-muscle-actin (αSMA expression in liver tissue extracts using western-blots and RT-PCR. Intra-hepatic NK cells were isolated and stained for NK activity (CD107a by flow cytometry. Liver histopathology (H&E staining, thyroid tumor mass and serum alanine aminotransferase (ALT, serum vascular endothelial growth factor (VEGF and free-T4 levels were also assessed.Ex-vivo: NPA cells were co-cultured with intra-hepatic NK cells isolated from fibrotic mice with/without the tumor were analyzed for CFSE-proliferations. Both tumor groups (with/without hepatic-fibrosis excreted higher serum free T4 levels. Hepatic-fibrosis increased tumor weight and size and serum free-T4 levels. In addition, tumor induction increased liver injury (both hepatic-fibrosis, necro-inflammation and serum ALT levels. In addition, tumor-bearing animals with hepatic-fibrosis had increased NK activity. NPA tumor-bearing animals increased fibrosis in spite of increased NK activity; probably due to a direct effect through increased serum free-T4 excretions. Serum VEGF levels were significantly increased in the fibrotic- bearing tumor groups compared to the non-fibrotic groups. In-vitro, NK cells from fibrotic tumor-bearing animals reduced proliferation of NPA cells. This decrease is attributed to increase NK cells activity in the fibrotic animals with the NPA tumors.Our results propose that NK cells although were

    Salivary gland-type tumors have been rarely described in the thyroid gland. Mammary Analog Secretory Carcinoma (MASC) is a recently defined type of salivary gland carcinoma characterized by a t(12;15)(p13;q25) resulting in an ETV6-NTRK3 fusion gene. We report 3 cases of MASC involving the thyroid gland without clinical evidence of a salivary gland or breast primary; the clinico-pathologic characteristics are reviewed. Assessment for rearrangement of the ETV6 (12p13) locus was conducted by fluorescence in situ hybridization (FISH) on representative FFPE sections using an ETV6 break apart probe (Abbott Molecular, Des Plaines, IL, USA). The patients were two females (52 and 55 years-old) and 1 male (74 years-old). The tumors were poorly circumscribed solid white tan nodules involving the thyroid. Histologically, they were invasive and showed solid, microcystic, cribriform, and tubular growth patterns composed of variably bland polygonal eosinophilic cells with vesicular nuclear chromatin and conspicuous nucleoli. All three cases showed metastasis to lymph nodes; one case showed lateral neck involvement. The tumor cells were positive for S100 and mammaglobin. GATA-3 and PAX-8 were positive in 2 cases, one of which only focally so. All three cases were negative for TTF-1 and thyroglobulin. Rearrangement of the ETV6 locus was confirmed in all cases and a diagnosis of MASC rendered for each case. A site of origin distinct from the thyroid gland was not identified, with a median follow up of 24 months. MASC may rarely involve the thyroid gland. The origin of these lesions is unknown; while an origin from ectopic salivary gland-type cells is entertained, a metastatic origin from an occult primary cannot be definitively excluded at this time. Given the histologic (follicular-like microcystic pattern with colloid-like secretions and papillary pattern), immunophenotypic (PAX-8), and even molecular overlap, MASC can be mistaken for papillary thyroid carcinoma and should be

    Full Text Available Radioactive iodine (RAI therapy plays an important role in the management of thyroid malignancies. Leukemia is a very rare complication of radioactive therapy. There are very few case reports with doses below 100 mCi causing leukemia. We report a case of papillary carcinoma of the thyroid treated with 80 mCi RAI who later developed acute myeloid leukemia. Thus, all patients with thyroid carcinoma treated with RAI should undergo periodic hematological examinations irrespective of RAI dose.

    Thyroglossal duct remnants (TGDR), most often cysts, are the most common type of developmental abnormalities of the thyroid gland. In about 1 to 2% of TGDR neoplastic transformation occurs. Papillary carcinoma of the thyroid may be encountered in over 90% of such cases. Two cases of primary papillary carcinoma of the thyroid in TGDR in young girls are presented. The diagnostic and therapeutic problems are shared, and up-to-date management guidelines in similar cases are discussed.

    In the department of nuclear medicine at Ibn Sina university hospital. Thyroid carcinoma follow-up strategy has been modified and includes cervical ultrasonography and thyroglobulin measurement. The role of radio-iodine scanning in the management of differentiated thyroid carcinoma is decreasing. Papillary and follicular carcinoma have good prognosis but late metastases exist and can lead to death. A lifelong follow-up is therefore mandatory. The main goal of follow-up is to detect earlier persistent or recurrent disease. (authors)

    Full Text Available Context: The diagnosis of papillary thyroid carcinoma (PTC is based on nuclear features. These features may be present in focal areas in benign thyroid diseases and follicular adenoma (FA, leading to diagnostic difficulty. Aims: To evaluate the expression and pattern of the distribution of cytokeratin 19 (CK19 in PTC and compare its reactivity with other neoplastic and non-neoplastic conditions to assess its potential as a useful marker for PTC. Materials and Methods: Twenty two cases of papillary carcinoma (usual type, follicular and diffuse sclerosing variant, eight follicular adenomas, eight multinodular goiters (MNG were collected for a period of two years and six months. Sections were taken from thyroidectomy specimens fixed in 10% buffered neutral formalin. Hematoxylin and eosin staining and immunohistochemical staining for CK19 were done using standard protocol. Results were semiquantitatively scored as follows: 1+ (75%, and then analyzed. Statistical Analysis and Results: All 22 (100% papillary carcinomas showed diffuse and strong (3+ and 4+ CK19 expression. Six out of eight (75% FAs and four out of eight (50% MNG were positive for CK19, but it was of weaker intensity (1+ and 2+ and focal in distribution. Conclusion: Focal CK19 staining may be found in benign disease, but diffuse and strong positivity is characteristic of PTC, which can be used in the diagnosis of PTC in lesions of equivocal morphological appearances.

    2014-03-01

    Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is caused most frequently by a bronchial carcinoid tumor or by small cell lung cancer. Medullary thyroid carcinoma (MTC is a rare etiology of ectopic ACTH syndrome. We describe a case of Cushing syndrome due to ectopic ACTH production from MTC in a 48-year-old male. He was diagnosed with MTC 14 years ago and underwent total thyroidectomy, cervical lymph node dissection and a series of metastasectomies. MTC was confirmed by the pathological examination of the thyroid and metastatic mediastinal lymph node tissues. Two years after his last surgery, he developed Cushingoid features, such as moon face and central obesity, accompanied by uncontrolled hypertension and new-onset diabetes. The laboratory results were compatible with ectopic ACTH syndrome. A bilateral adrenalectomy improved the clinical and laboratory findings that were associated with Cushing syndrome. This is the first confirmed case of ectopic ACTH syndrome caused by MTC in Korea.

    Background: Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. Since the American Thyroid Association's (ATA's) guidelines for the management of these disorders were revised in 2009, significant scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, researchers, and health policy makers on published evidence relating to the diagnosis and management of thyroid nodules and differentiated thyroid cancer. Methods: The specific clinical questions addressed in these guidelines were based on prior versions of the guidelines, stakeholder input, and input of task force members. Task force panel members were educated on knowledge synthesis methods, including electronic database searching, review and selection of relevant citations, and critical appraisal of selected studies. Published English language articles on adults were eligible for inclusion. The American College of Physicians Guideline Grading System was used for critical appraisal of evidence and grading strength of recommendations for therapeutic interventions. We developed a similarly formatted system to appraise the quality of such studies and resultant recommendations. The guideline panel had complete editorial independence from the ATA. Competing interests of guideline task force members were regularly updated, managed, and communicated to the ATA and task force members. Results: The revised guidelines for the management of thyroid nodules include recommendations regarding initial evaluation, clinical and ultrasound criteria for fine-needle aspiration biopsy, interpretation of fine-needle aspiration biopsy results, use of molecular markers, and management of benign thyroid nodules. Recommendations regarding the initial management of thyroid cancer include those relating to screening for thyroid cancer, staging and risk assessment, surgical management, radioiodine remnant ablation and therapy

    Thyroid cancer is a heterogeneous disease with several subtypes characterized by cytological, histological and genetic alterations, but the involvement of epigenetics is not well understood. Here, we investigated the role of aberrant DNA methylation in the development of well-differentiated thyroid tumors. We performed genome-wide DNA methylation profiling in the largest well-differentiated thyroid tumor series reported to date, comprising 83 primary tumors as well as 8 samples of adjacent normal tissue. The epigenetic profiles were closely related to not only tumor histology but also the underlying driver mutation; we found that follicular tumors had higher levels of methylation, which seemed to accumulate in a progressive manner along the tumorigenic process from adenomas to carcinomas. Furthermore, tumors harboring a BRAF or RAS mutation had a larger number of hypo- or hypermethylation events, respectively. The aberrant methylation of several candidate genes potentially related to thyroid carcinogenesis was validated in an independent series of 52 samples. Furthermore, through the integration of methylation and transcriptional expression data, we identified genes whose expression is associated with the methylation status of their promoters. Finally, by integrating clinical follow-up information with methylation levels we propose etoposide-induced 2.4 and Wilms tumor 1 as novel prognostic markers related to recurrence-free survival. This comprehensive study provides insights into the role of DNA methylation in well-differentiated thyroid cancer development and identifies novel markers associated with recurrence-free survival. © 2013 UICC.

    2012-05-01

    Full Text Available Abstract 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.

    We report the case of a primary mucinous carcinoma of the thyroid in a man of 74 who had a 4-cm nodule in the right lobe of the thyroid, with a solido-cystic appearance on ultrasound associated with lymph node metastases. On scintigraphy, the nodule was hot and not extinctive. The patient underwent total thyroidectomy with a ipsilateral right lymph node dissection. The immunohistochemical study showed the negativity of CK 7 and CK 20 and the positivity of thyroglobulin and TTF 1. Postoperatively the rate of blood thyroglobulin 3 months after surgery had collapsed to 0.17ng/ml. The evolution was marked by the appearance of pulmonary metastasis and the patient died 4 months after surgery. Histological study showed the presence of almas of neoplastic cells surrounded by large deposits of extracellular mucin. Primitive mucinous carcinoma of the thyroid is a rare tumor which differential diagnosis is established on the positive immunohistochemistry of thyroglobulin and TTF1 but negative for other markers.

    From 1975 to 1982, 32 patients with a diagnosis of anaplastic carcinoma of the thyroid were entered into a protocol of hyperfractionated accelerated radiotherapy. The tumor dose was 30-45 Gy at 1 Gy per fraction given 4 times a day at 3-h intervals. The results were disappointing with a median survival of less than 6 months. Two patients developed radiation myelopathy at 8 and 13 months, total spinal cord dose being 39.9 and 48.3 Gy, respectively. The risk of spinal cord damage was much higher than expected. The possible radiobiological causes and clinical implications are discussed.

    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.

    Multifocal fibrosing thyroiditis (MFT) is characterized by numerous foci of fibrosis in a stellate configuration with fibroelastotic and fibroblastic centers entrapping epithelial structures. MFT has been proposed as a risk factor for papillary thyroid carcinoma (PTC) development. We attempted to identify whether MFT showed such molecular changes and could possibly be related to PTC. We identified seven cases of PTC with MFT in our institutional pathology database and personal consult service of one of the authors (VAL) for the years 1999 to 2012. Areas of PTC, MFT, and normal tissue were selected for BRAF analysis. Macro-dissection, DNA extraction and PCR amplification, and pyrosequencing were performed to detect BRAF mutations in codon 600. All of the MFT lesions and normal thyroid tissue were negative for BRAF mutations. Of the seven PTCs analyzed, five (71 %) were negative for BRAF mutations, while two cases were positive. In our study, none of the MFT lesions harbored BRAF mutations, whereas 29 % (two of seven) PTCs in the same gland were positive. Hence, in this small study, we found no evidence that the MFT lesion is a direct precursor to PTC. It is likely an incidental bystander in the process and a reflection of the background thyroiditis.

    2013-08-01

    Full Text Available INTRODUCTION: The forkhead box P3 (FOXP3 plays a role in cell development and control. In the presence of abnormal FOXP3 expression, tumor cells may evade the immunosurveillance of lymphoid cells, the first step for the maintenance of cancer cells in the thyroid tissue. OBJECTIVE: To identify the presence of FOXP3 in papillary thyroid carcinoma (PTC with and without Hashimoto's Thyroiditis (HT. METHODS: We conducted a series study of cases collected from 2000 to 2008, when 1,438 thyroidectomies were performed. We selected those diagnosed with PTC, comprising 466 cases. 30 patients were randomly selected for purposes of immunohistochemistry with antibodies against FOXP3. RESULT: FOXP3 revealed high positivity for PTC and positive immunostaining was present in 21 (72.4% from all analyzed cases. There was no difference regarding coexistent HT or not. DISCUSSION AND CONCLUSION: In the present study, it was evidenced that the focal or diffuse FOXP3 expression was commonly observed in neoplastic cells from PTC, hence indicating that the assessment of this molecule expression in suspected cases of thyroid cancer may contribute to its diagnosis.

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

    Directory of Open Access Journals (Sweden)

    Francesco Cetta

    2015-01-01

    Full Text Available 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.

    Full Text Available The purpose of this study was to assess the relationship between vitamin D receptor gene (VDR expression and prognostic factors in papillary thyroid cancer (PTC. mRNA sequencing and somatic mutation data from The Cancer Genome Atlas (TCGA were analyzed. VDR mRNA expression was compared to clinicopathologic variables by linear regression. Tree-based classification was applied to find cutoff and patients were split into low and high VDR group. Logistic regression, Kaplan–Meier analysis, differentially expressed gene (DEG test and pathway analysis were performed to assess the differences between two VDR groups. VDR mRNA expression was elevated in PTC than that in normal thyroid tissue. VDR expressions were high in classic and tall-cell variant PTC and lateral neck node metastasis was present. High VDR group was also associated with classic and tall cell subtype, AJCC stage IV and lower recurrence-free survival. DEG test reveals that 545 genes were upregulated in high VDR group. Thyroid cancer-related pathways were enriched in high VDR group in pathway analyses. VDR mRNA overexpression was correlated with worse prognostic factors such as subtypes of papillary thyroid carcinoma that are known to be worse prognosis, lateral neck node metastasis, advanced stage and recurrence-free survival.

    Full Text Available Hyalinizing Trabecular Adenoma (HTA of the thyroid is a rare neoplasm that was first described by Carney in 1987. It is a tumor of follicular derivation with peculiar nuclear, architectural, histochemical, and immunohistochemical features. We report a case of Hyalinizing trabecular adenoma in a 36-year-old woman with enlarged thyroid lobe. Ultrasonographic features and fine needle aspiration cytology (FNAC of the enlarged thyroid was performed and the diagnosis given was Papillary carcinoma of the thyroid. The patient underwent total thyroidectomy, with a histopathological diagnosis of hyalinizing trabecular Adenoma (HTA. We present this case in view of its rarity and to discuss the clinical and diagnostic approach, including the role of FNAC, and the pathologic features of HTA with special reference to the possible differential diagnosis and also review of literature. Although rare cases of malignant Hyalinizing trabecular adenoma (HTA have been documented, this tumor should be considered a benign neoplasm or at most, a neoplasm of extremely low malignant potential, however invasion of the capsule should be considered on histopathology. An awareness of hyalinizing trabecular adenomas and their characteristic features is valuable for their recognition and management as well as for the possible prevention of over diagnosis and over treatment for benign disease

    The authors report three siblings (two sisters and their aunt, aged 20, 22 and 36, respectively) with familial adenomatous polyposis (FAP) and papillary thyroid carcinoma. After diagnosis of FAP, a single, non palpable nodule was revealed in each patient by routine screening ultrasonography of the gland. The diagnosis of papillary carcinoma was made by fine-needle-aspiration biopsy of the nodules and confirmed by histologic examination of surgical specimens. A review of the literature reveals about 40 reports of such an association, that is considered not fortuitous. Nevertheless, in this family the association seems to be a distinctive, clinical feature of the syndrome, affecting three out of five members intensively screened for extracolonic lesions.

    Full Text Available Follicular thyroid carcinoma classically accounts for 10–32% of thyroid malignancies. We determined the incidence and the behaviour of follicular thyroid carcinoma in an endemic goitre area. A comparative analysis between minimally invasive and widely invasive follicular thyroid carcinoma was performed. The medical records of all patients who underwent thyroidectomy from October 1998 to April 2012 for thyroid malignancies were reviewed. Those who had a histological diagnosis of follicular carcinoma were included. Among 5203 patients, 130 (2.5% were included. Distant metastases at presentation were observed in four patients. Sixty-six patients had a minimally invasive follicular carcinoma and 64 a widely invasive follicular carcinoma. In 63 patients an oxyphilic variant was registered. Minimally/widely invasive ratio was 41/26 for usual follicular carcinoma and 25/38 for oxyphilic variant (P<0.05. Patients with widely invasive tumors had larger tumors (P<0.001 and more frequently oxyphilic variant (P<0.05 than those with minimally invasive tumours. No significant difference was found between widely invasive and minimally invasive tumors and between usual follicular carcinoma and oxyphilic variant regarding the recurrence rate (P=NS. The incidence of follicular thyroid carcinoma is much lower than classically retained. Aggressive treatment, including total thyroidectomy and radioiodine ablation, should be proposed to all patients.

    Full Text Available We present 2 patients with pituitary metastases from thyroid carcinoma—the first from anaplastic thyroid carcinoma and the second from follicular thyroid carcinoma. The first patient, a 50-year-old lady, presented with 2-week history of hoarseness of voice, dysphagia, dyspnoea, and neck swelling. Imaging revealed metastatic thyroid cancer to lymph nodes and bone. Histology from surgery confirmed anaplastic thyroid cancer. She was found to have pituitary metastases postoperatively when she presented with nonvertiginous dizziness. She subsequently underwent radiotherapy and radioiodine treatment but passed away from complications. The second patient, a 65-year-old lady, presented with loss of appetite and weight with increased goitre size and dyspnoea. Surgery was performed in view of compressive symptoms and histology confirmed follicular thyroid carcinoma. Imaging revealed metastases to bone, lung, and pituitary. She also had panhypopituitarism with hyperprolactinemia and diabetes insipidus. She received radioiodine therapy but eventually passed away from complications.

    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.

    The aim of this study was to evaluate the expression of papillary thyroid carcinoma (PTC)-associated tumor markers in follicular epithelial dysplasia showing PTC-like nuclear alterations (FED) in Hashimoto's thyroiditis (HT) and to explore the relationship between HT and PTC. In this study, 43 PTC, 18 HT with FED and 16 peritumoral benign thyroid tissues were immunohistochemically analyzed for CK19, galectin-3, HBME-1, CD56, claudin-1 and NGAL expression. Our research revealed that in HT, the expression of CK19, galectin-3, HBME-1, claudin-1 and NGAL was focal and limited to FED, while CD56 was strongly positive in FED and most Hürthle cells. The stain intensity of CK19, claudin-1 and NGAL in FED decreased compared with PTC, but were significantly higher than that in peritumoral benign thyroid tissues (all P 0.05). In conclusion, In HT, FED might be a precancerous condition closely associated with PTC development as they have overlaps in cytological and immunomarker profiles, indicating that in patients with HT, under prolonged stimuli from chronic inflammation, part of follicular epithelia may show regeneration, hyperplasia, Hürthle cell metaplasia and dysplasia, eventually malignant transformation. Hence, long term follow-up and regular inspection would be necessary for Hashimoto's thyroiditis with FED.

  3. Aberrant Expression of Posterior HOX Genes in Well Differentiated Histotypes of Thyroid Cancers

    Full Text Available 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.

    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.

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    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.

    Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and constitutes more than 70% of thyroid malignancies. Although TNM staging is the most widely used parameter for determination of therapeutic plans, recent studies have suggested that different histopathologic variants of PTC can also have different clinical courses and patient prognoses. Sonographic criteria for PTC are well established and include a taller-than-wide shape, an irregular margin, microcalcifications, and marked hypoechogenicity. The role of sonography has expanded to enable the characterization of PTC variants based on their sonographic features. Tall cell and diffuse sclerosing variants appear to have more aggressive clinical courses with unfavorable prognoses, whereas the more recently described cribriform-morular and Warthin-like variants have relatively indolent clinical courses. The prognoses of patients with follicular, solid, columnar cell, and oncocytic variants are still controversial and may be similar to the prognosis of conventional PTC. Understanding the sonographic characteristics of PTC variants with clinicopathologic correlation may be helpful for suggesting an appropriate treatment plan.

    Background Glucosylceramide synthase (GCS) can reduce ceramide levels and help cells escape ceramide-induced apoptosis,thus leading to multidrug resistance (MDR).However,its expression and clinical significance in thyroid neoplasms still remain unclear.We aimed to elucidate the expression of GCS and explore its correlation with the clinicopathological characteristics in papillary thyroid carcinomas (PTCs).Methods We retrospectively investigated GCS protein expression level in tissue specimens obtained from 108 consecutive PTC patients by immunohistochemistry and Western blotting.Results GCS was weakly positive or negative in normal follicular cells,but it was frequently overexpressed in PTC cells.GCS overexpression was associated with primary tumor size,local infiltration,lymph node metastasis,and local recurrence,but not associated with gender,age,pathological variants,tumor multifocality,tumor stage or distant metastasis.Western blotting also showed that GCS protein levels were much higher in PTCs' tissues than in normal thyroid tissues.Conclusion GCS was upregulated in PTCs and might be an independent factor affecting prognosis.

    We report the case of a 25 year-old patient with no medical history, admitted to our unit for nodular goiter of the right lobe without clinical or laboratory signs of hyperthyroidism. We carried out a right lobo-isthmectomy revealing the association of tuberculosis and thyroid papillary carcinoma. A left lobectomy has, therefore, been performed in a second stage. The patient underwent a six-month antituberculosis treatment with a good clinical outcome. We discuss this rare association and its best diagnostic and therapeutic support, with a review of the literature.

    This study compares clinical, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and pathology findings in 16 prospectively, and seven retrospectively recruited dogs presented for suspected thyroid carcinoma. Of these, 17 were confirmed thyroid carcinoma, while six were initially misdiagnosed. These included four carotid body tumors, one para-esophageal abscess, and one undifferentiated squamous cell carcinoma. Thyroid carcinomas occurred in older dogs without evidence of sex predilection, and were more often unilateral. All were large, heterogeneous, moderately to strongly vascularized, and most commonly contained areas of dystrophic mineralization and/or fluid accumulations. On MRI, thyroid carcinomas appeared hyperintense compared to surrounding musculature in all imaging sequences used, while on CT they had a lower attenuation value than normal thyroid gland tissue. Histologically confirmed tumor capsule disruption with invasion of the surrounding structures was most commonly detected with MRI. Palpation was not an accurate predictor of locally invasive vs. well-encapsulated masses. Computed tomography had the highest specificity (100%) and MRI had the highest sensitivity (93%) in diagnosing thyroid carcinoma, while ultrasound had considerably lower results. We conclude that ultrasound is adequate for use as a screening tool for dogs with suspected thyroid carcinoma, but recommend either CT or MRI for preoperative diagnosis and staging.

    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. 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. 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.

    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.

    Abstract This study was designed to retrospectively compare the sonographic features of medullary thyroid carcinoma (MTC) and the features of papillary thyroid carcinoma (PTC). A total of 97 patients with 127 MTCs between January 2000 and January 2016 and 107 consecutive patients with 132 PTCs were included in this study. Two radiologists retrospectively determined the sonographic features and compared the findings of MTCs and PTCs. Compared with the patients with PTCs, the patients with MTCs were older (46.9 years vs 42.9 years, P = 0.016) and the male proportion was higher (53.6% vs 33.6%, P = 0.005). Most of the MTCs had an irregular shape (72.4%), a length/width ratio hypoechogenicity (96.9%), heterogeneous echotexture (76.4%), no cystic change (78.7%), calcification (63.8%), and hypervascularity (72.4%). There was no significant difference in the boundary, peripheral halo ring, echogenicity, and calcification between the MTCs and PTCs. However, compared with the PTCs, a larger size (2.2 vs 1.2 cm, P hypoechogenicity, the presence of microcalcifications, and increased intranodular vascularity. However, MTCs tend to possess these suspicious sonographic features less often than PTCs, with the exception of hypervascularity, which was more frequent in MTCs. PMID:27930537

    Pituitary adenylate cyclase activating polypeptide (PACAP) belongs to the vasoactive intestinal peptide-secretin-glucagon peptide family, isolated first from ovine hypothalamus. The diverse physiological effects of PACAP are known mainly from animal experiments, including several actions in endocrine glands. Alteration of PACAP expression has been shown in several tumors, but changes in expression of PACAP and its specific PAC1 receptor in human thyroid gland pathologies have not yet been investigated. Therefore, the aim of the present study was to investigate expression of PACAP and its PAC1 receptor in human thyroid papillary carcinoma, the most common endocrine malignant tumor. PACAP and PAC1 receptor expressions were investigated from thyroid gland samples of patients with papillary carcinomas. The staining intensity of follicular epithelial cells and thyroid colloid of tumor tissue was compared to that of tumor-free tissue in the same thyroid glands in a semi-quantitative way. Our results reveal that both PACAP(-like) and PAC1 receptor(-like) immunoreactivities are altered in papillary carcinoma. Stronger PACAP immunoreactivity was observed in active follicles. Colloidal PACAP immunostaining was either lacking or very weak, and more tumorous cells displayed strong apical immunoreactivity. Regarding PAC1 receptor, cells of the normal thyroid tissue showed strong granular expression, which was lacking in the tumor cells. The cytoplasm of tumor cells displayed weak, minimal staining, while in a few tumor cells we observed strong PAC1 receptor expression. This pattern was similar to that observed in the PACAP expression, but fewer in number. In summary, we showed alteration of PACAP and PAC1 receptor expression in human thyroid papillary carcinoma, indicating that PACAP regulation is disturbed in tumorous tissue of the thyroid gland. The exact role of PACAP in thyroid tumor growth should be further explored.

    The incidence of thyroid carcinoma increases worldwide with the development of diagnosis and has become one of the most commonly occurring endocrine system tumors. Usually,thyroid carcinoma can be classified into papillary thyroid carci-noma,follicular thyroid carcinoma,medullary thyroid carcinoma,poorly differentiated thyroid carcinoma and anaplastic thyroid carcinoma based on the histology and it has been reported that the prognosis closely connects with the histopathology of this tumor. Several genes such as IG20/MADD,RET and BRAF and molecules are involved in tumorigenesis in thyroid and studies at the mo-lecular level provide a promising approach for diagnosis and clinical therapy. Novel molecular-targeted therapy based on the molecu-lar pathophysiology has been in the stage of clinical trials and it brings hopes for refractory thyroid carcinomas.%随着诊断技术的发展,甲状腺癌的发病率在世界范围内上升,成为最常见的内分泌肿瘤。通常,根据原发肿瘤的组织学特点可以将甲状腺癌分为甲状腺乳头状癌(papillary thyroid carcinoma,PTC)、甲状腺滤泡状癌(follicular thyroid carcinoma,FTC)、甲状腺髓样癌(medullary thyroid carcinoma,MTC)、低分化甲状腺癌及未分化甲状腺癌(anaplastic thyroid carcinoma,ATC),研究证实甲状腺癌的病理分型与其预后关系密切。在甲状腺肿瘤组织中发现多种基因(如IG20/MADD、RET、BRAF等)和分子(如基质金属蛋白酶)参与肿瘤的发生,分子水平研究成为诊断和治疗的新方向,基于分子病理生理学的新型靶向治疗方法已进入临床研究阶段,为难以手术根治的甲状腺癌的治疗带来希望。

    Purpose: Illustrate the result of the diagnosis by multimodality imaging (MRI, scintigraphy {sup 123}I-Mibg, PET/CT{sup 18}F-F.D.G. and {sup 18}F-F DOPA) with liver metastasis looking like a single angioma in a patient with atypical medullary thyroid carcinoma. Conclusions: Angiomas must be taken into account in the differential diagnosis of liver metastasis of endocrine tumors, particularly in the case of small injuries where it may be difficult to differentiate a peripheral nodular contrast enhancement of a globular enhancement characteristics of angiomas.

    There has been increasing interest in a risk-adopted management strategy known as dynamic risk stratification following the revised American Thyroid Association guidelines for differentiated thyroid cancer. We aimed to evaluate the usefulness of dynamic risk stratification for predicting structural disease in pediatric differentiated thyroid cancer patients. We retrospectively reviewed 130 pediatric differentiated thyroid cancer patients (≤19 years) who were treated between 1996 and 2015 at Samsung Medical Center. Patients were stratified according to three American Thyroid Association initial risk group (low, intermediate, or high risk) and four dynamic risk stratification group (excellent, indeterminate, biochemical incomplete, or structural incomplete). Based on dynamic risk stratification strategy, structural disease was identified 3.9% in the excellent group, 9.7% in the indeterminate group, 76.9% in the biochemical incomplete group, and 100% in the structural incomplete group. The hazard ratios of the structural disease were 18.10 (P < 0.001) in the biochemical incomplete group, and 19.583 (P < 0.001) in the structural incomplete group compared to the excellent group. The prevalence of structural disease also increased as American Thyroid Association initial risk classification increased (5.9% in the low-risk group, 13.6% in the intermediate-risk group, and 45% in the high-risk group). The hazard ratios of structural disease in the high-risk group was 10.296 (P < 0.001) in compared to the low-risk group. Dynamic risk stratification based on patient responses to initial therapy was able to effectively predict the risk of structural disease in a pediatric population, and as a follow-up strategy, may work as well in pediatric differentiated thyroid cancer patients as it does in adult differentiated thyroid cancer patients.
