Sample records for anaplastic thyroid carcinoma

  1. Leptomeningeal metastases from anaplastic thyroid carcinoma

    International Nuclear Information System (INIS)

    Anaplastic thyroid carcinoma is an extremely aggressive neoplasm that accounts for 1-3% of all thyroid cancers. ' Most patients have metastatic disease at presentation and die in a short period of time, often with uncontrolled local disease. We report a case of anaplastic thyroid cancer characterised by good response to initial treatment both locally and in distant metastases, and the subsequent development of refractory metastatic disease in an unusual site, the leptomeninges

  2. Anaplastic thyroid carcinoma: outcome and prognostic factors

    International Nuclear Information System (INIS)

    Purpose: Anaplastic carcinoma of the thyroid has been described as a rapidly progressive disease. We assessed the outcome and prognostic factors in patients with anaplastic thyroid carcinoma at our institution. Materials and Methods: Between 1975 and 1995, 37 patients were seen and treated at our institution with pathologically proven anaplastic carcinoma of the thyroid gland. Patients ranged in age from 49 to 97 years old (median 73 years) and females were represented in a 2:1 ratio. Many patients had history of prior benign thyroid disease (17) or low grade malignancy (6). Other medical illnesses were frequently present in these patients, including 5 with diabetes, 1 scleroderma, 1 sarcoidosis and 1 polycythemia vera. 12 patients had metastatic disease at presentation. 26 patients had locally advanced (T4) disease. The time from diagnosis to treatment was never longer than 1 month. Management was most often with biopsy only (22 patients) and local irradiation (34 patients, median dose 52.5 Gy). 15 patients had primary surgical resection, one of which had negative surgical margins. 11 patients received chemotherapy, 9 with Adriamycin-based regimens. Follow-up ranged from 4 months to 11 years, with a mean of 11 months. Results: 26 patients had a local response, either partial or complete, to their treatment regimen. However, systemic disease was an important cause of failure. 9 patients (24%) survived at least one year from diagnosis; 3 (8%) survived beyond two years. The development of metastases occurred quickly in originally localized disease, at a median of 2 months. Metastases occurred most commonly in the lung (11 of 14 cases), but also occured in brain (2), liver (1), bone (1) and pericardium (1). Performance status, sex, metastatic disease, hyperfractionation, treatment modalities, RT dose, age and response to treatment were assessed as prognostic factors for survival. On univariate analysis, age over 70 (p=.004) and failure to attain a complete response to

  3. Anaplastic carcinoma following well-differentiated thyroid cancer: etiological considerations

    International Nuclear Information System (INIS)

    Most cases of anaplastic thyroid carcinoma can be pathologically and often historically associated with the presence of low-grade (differentiated) cancer in the thyroid. That radiation therapy to the differentiated tumor plays an etiologic role in the transformation of a differentiated to an undifferentiated tumor has been suggested. If such therapy can be implicated, is there a difference in risk between external radiotherapy or radioactive iodine. Review of the literature discloses that more anaplastic carcinoma of the thyroid develop in patients without a history of prior radiation than in individuals who have received radiation. We report our recent experience with two patients who demonstrated the sequence of well-differentiated followed by anaplastic thyroid cancer subsequent to radiation and review the question

    Radioactive iodine (RAI) therapy has been used as a treatment option for Graves' disease, and it has been widely accepted to be safe. On the other hand, some evidence suggests that RAI therapy is possibly associated with a small increased risk of thyroid cancer. Herein, we report a rare case of anaplastic thyroid carcinoma (ATC) associated with Graves' disease, following RAI treatment. A 42-year-old woman had been diagnosed with Graves' disease and although she was treated with an antithyroid...

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

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

  12. Iodide uptake in human anaplastic thyroid carcinoma cells after transfer of the human thyroid peroxidase gene

    International Nuclear Information System (INIS)

    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 Na125I. 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 studies

    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.

    Primary non-Hodgkin's lymphoma (LY) and anaplastic carcinoma (AC) of the thyroid gland are rare malignant tumors, and the initial symptoms of these diseases are very similar. The aim of our study was to compare the characteristics of the two diseases using computed tomographic (CT) scans in order to make an accurate differential diagnosis. Ten patients with LY and 10 with AC were analyzed. Differences in the CT findings of the two diseases were evaluated before treatment and statistically tested with either Student's t-test or the chi-square test. In the analysis of characteristics of CT imaging, the existence of calcification and necrosis, and heterogeneous tumor were dominant findings in AC, and there was a statistically significant difference in frequency between the two diseases (p<0.01). Calcification detected in AC was usually multiple and/or gross (mean size: {phi}8.2 mm). All lymphadenopathies were delineated as having the same homogeneous attenuation as the tumors in the thyroid gland in LY, but were shown as irregular rim enhancement in AC. The CT features of the two diseases are characteristic in terms of calcification, necrosis, and tumor composition. Evaluation by means of CT imaging is useful in distinguishing between LY and AC.

    Full Text Available Anaplastic thyroid carcinoma (ATC is a rare and highly aggressive thyroid neoplasm. Bleeding from tumor is an uncommon, but potentially life-threatening complication requiring sophisticated intervention facilities which are not usually available at odd hours in emergency. We report the case of a 45-year-old woman who presented with exsanguinating hemorrhage from ATC and was treated by emergency total thyroidectomy. The patient is well three months postoperatively. Emergency total thyroidectomy is a viable option for palliation in ATC presenting with bleeding.

    Full Text Available Abstract Background Identification of effective systemic antineoplastic drugs against anaplastic thyroid carcinomas has particularly important implications. In fact, the efficacy of the chemotherapeutic agents presently used in these tumours, is strongly limited by their low therapeutic index. Methods In this study gemcitabine was entrapped within a pegylated liposomal delivery system to improve the drug antitumoral activity, thus exploiting the possibility to reduce doses to be administered in cancer therapy. The cytotoxic effects of free or liposome-entrapped gemcitabine was evaluated against a human thyroid tumour cell line. ARO cells, derived from a thyroid anaplastic carcinoma, were exposed to different concentrations of the drug. Liposomes formulations were made up of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine/cholesterol/1,2-distearoyl-sn-glycero-3-phosphoethanolamine-MPEG (8:3:1 molar ratio. Cell viability was assessed by both trypan bleu dye exclusion assay and fluorimetric analysis of cell DNA content. Results A cytotoxic effect of free gemcitabine was present only after 72 h incubation (ARO cell mortality increased of approximately 4 fold over control at 1 μM, 7 fold at 100 μM. When gemcitabine was encapsulated in liposomes, a significant effect was observed by using lower concentrations of the drug (increased cell mortality of 2.4 fold vs. control at 0.3 μM and earlier exposure time (24 h. Conclusion These findings show that, in vitro against human thyroid cancer cells, the gemcitabine incorporation within liposomes enhances the drug cytotoxic effect with respect to free gemcitabine, thus suggesting a more effective drug uptake inside the cells. This may allow the use of new formulations with lower dosages (side effect free for the treatment of anaplastic human thyroid tumours.

Fine needle aspiration was done and reported as anaplastic carcinoma of thyroid which thyroidectomy was planned. The slides were sent for second opinion. After review, with initial diagnosis of anaplastic carcinoma versus lymphoma, immunocytochemical study was performed. Smears were positive for B cell markers and negative for cytokeratin, so with the impression of diffuse large B cell lymphoma, the patient received two courses of chemotherapy by which the tumor disappeared during two weaks. Conclusion Despite previous reports, stating easy diagnosis of high-grade thyroid lymphoma on the grounds of cytomorphological features we like to emphasize, overlapping cytologic features of the curable high grade thyroid lymphoma form noncurable anaplastic thyroid carcinoma and usefulness of immunocytochemistry to differentiate these two disease.

  1. Investigation of the results of therapy of anaplastic thyroid gland carcinomas

    International Nuclear Information System (INIS)

    The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

  4. A bone metastases model of anaplastic thyroid carcinoma in athymic nude mice

    International Nuclear Information System (INIS)

    Anaplastic thyroid carcinoma (ATC), an aggressive form of thyroid cancer, represents less than 2% of all thyroid cancers. The survival of patients with ATC remains low especially when accompanied with bone metastasis. This study aims to establish a reproducible animal model of bone metastasis of ATC which may be useful for further research on novel treatment strategy. Eight 6-8 week old female athymic nude mice were randomly selected. ATC cell line ARO cells were injected into the left ventricular cavity of each mouse respectively. Each mouse was imaged using a dedicated small-animal PET/CT scanner after successful injection of [18F]-FDG under deep anesthesia. Pathological examination was carried out to confirm the bone metastases of ATC. Histopathology established ATC bone metastases in five nude mice’s tibia. Similarly, PET image displayed significantly increased radioactivity (P<0.01) in the established bone metastasis compared with the control normal tibia. Both micro-PET/CT and histomorphometric measurement confirmed the bone metastases model of ATC in nude mice by left ventricular cavity injection of ARO cell line. The bone metastases model of ATC will thus facilitate the understanding of its pathogenesis and aid in the development of novel therapies.

ATC accounts for 1-10% of all tumors derived from the thyroid gland. Classic chemotherapy approach based on platinum and anthracyclines regimens have been considered standard for the last decades. Novel multitarget agents have shown promising responses; however, no positive randomized clinical trials are available up to now. To our knowledge, the case we are presenting here is the first reported case showing clinical and visual activity using sunitinib as a salvage treatment in an ATC patient who was not fit to receive systemic chemotherapy treatment.

  8. Tumor-associated macrophages (TAMs form an interconnected cellular supportive network in anaplastic thyroid carcinoma.

    Directory of Open Access Journals (Sweden)

    Bernard Caillou

    Full Text Available BACKGROUND: A relationship between the increased density of tumor-associated macrophages (TAMs and decreased survival was recently reported in thyroid cancer patients. Among these tumors, anaplastic thyroid cancer (ATC is one of the most aggressive solid tumors in humans. TAMs (type M2 have been recognized as promoting tumor growth. The purpose of our study was to analyze with immunohistochemistry the presence of TAMs in a series of 27 ATC. METHODOLOGY/PRINCIPAL FINDINGS: Several macrophages markers such as NADPH oxidase complex NOX2-p22phox, CD163 and CD 68 were used. Immunostainings showed that TAMs represent more than 50% of nucleated cells in all ATCs. Moreover, these markers allowed the identification of elongated thin ramified cytoplasmic extensions, bestowing a "microglia-like" appearance on these cells which we termed "Ramified TAMs" (RTAMs. In contrast, cancer cells were totally negative. Cellular stroma was highly simplified since apart from cancer cells and blood vessels, RTAMs were the only other cellular component. RTAMs were evenly distributed and intermingled with cancer cells, and were in direct contact with other RTAMs via their ramifications. Moreover, RTAMs displayed strong immunostaining for connexin Cx43. Long chains of interconnected RTAMs arose from perivascular clusters and were dispersed within the tumor parenchyma. When expressed, the glucose transporter Glut1 was found in RTAMs and blood vessels, but rarely in cancer cells. CONCLUSION: ATCs display a very dense network of interconnected RTAMs in direct contact with intermingled cancer cells. To our knowledge this is the first time that such a network is described in a malignant tumor. This network was found in all our studied cases and appeared specific to ATC, since it was not found in differentiated thyroid cancers specimens. Taken together, these results suggest that RTAMs network is directly related to the aggressiveness of the disease via metabolic and trophic

    Full Text Available BACKGROUND 131I is usually employed for the therapy of hyperfunctioning thyroid diseases. This β-emitting radioisotope acts releasing its radiations in small tissue volumes, but it is mandatory to consider, also for the small doses, the carcinogenic risk, well documented with the high 131I dosages used to cure differentiated thyroid cancers. METHODS We describe a case of anaplastic thyroid carcinoma appeared 4 years after therapy with 131I for Graves’ disease. The patient was treated both surgically and with thyonamides for Graves’ disease 20 years before; thereafter she underwent simple nephrectomy owing to Grawitz disease. After some years of well being, she was treated with 131I for a relapse of Graves’ disease. Four years later, she was treated with interleukin-2 and TNF-α, owing to distant metastases (pancreas, liver and lung of Grawitz cancer. Some months later, because of a rapid enlargement of the thyroid gland, she was thyroidectomized and anaplastic thyroid cancer was histologically documented. DISCUSSION AND CONCLUSIONS It is very difficult to investigate the possible transformation of a benign thyroid lesion to a malignant one, and data from the literature are conflicting. Fractioned doses of 131I are known to induce less cancers than high doses: they allow DNA to repair. Nevertheless, in patients with altered or non valid genetic repair’s mechanisms (i.e. patients with p53 mutations and, for this reason, prone to develop cancers, even low doses of 131I can induce carcinogenetic effects. In a patient with a history of cancer, who subsequently develops hyperthyroidism, even low doses of 131I can induce anaplastic thyroid cancer; in these subjects, therefore, other treatments than 131I could be preferred for the therapy of Graves’ disease. In our peculiar case, moreover, some studies have noteworthy demonstrated that certain cytokines (IL-1, TGF-β1 e TNF-α can, rather than inhibit, induce anaplastic thyroid cancer cells

    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.

  13. In vitro identification and characterization of CD133(pos cancer stem-like cells in anaplastic thyroid carcinoma cell lines.

    Full Text Available BACKGROUND: Recent publications suggest that neoplastic initiation and growth are dependent on a small subset of cells, termed cancer stem cells (CSCs. Anaplastic Thyroid Carcinoma (ATC is a very aggressive solid tumor with poor prognosis, characterized by high dedifferentiation. The existence of CSCs might account for the heterogeneity of ATC lesions. CD133 has been identified as a stem cell marker for normal and cancerous tissues, although its biological function remains unknown. METHODOLOGY/PRINCIPAL FINDINGS: ATC cell lines ARO, KAT-4, KAT-18 and FRO were analyzed for CD133 expression. Flow cytometry showed CD133(pos cells only in ARO and KAT-4 (64+/-9% and 57+/-12%, respectively. These data were confirmed by qRT-PCR and immunocytochemistry. ARO and KAT-4 were also positive for fetal marker oncofetal fibronectin and negative for thyrocyte-specific differentiating markers thyroglobulin, thyroperoxidase and sodium/iodide symporter. Sorted ARO/CD133(pos cells exhibited higher proliferation, self-renewal, colony-forming ability in comparison with ARO/CD133(neg. Furthermore, ARO/CD133(pos showed levels of thyroid transcription factor TTF-1 similar to the fetal thyroid cell line TAD-2, while the expression in ARO/CD133(neg was negligible. The expression of the stem cell marker OCT-4 detected by RT-PCR and flow cytometry was markedly higher in ARO/CD133(pos in comparison to ARO/CD133(neg cells. The stem cell markers c-KIT and THY-1 were negative. Sensitivity to chemotherapy agents was investigated, showing remarkable resistance to chemotherapy-induced apoptosis in ARO/CD133(pos when compared with ARO/CD133(neg cells. CONCLUSIONS/SIGNIFICANCE: We describe CD133(pos cells in ATC cell lines. ARO/CD133(pos cells exhibit stem cell-like features--such as high proliferation, self-renewal ability, expression of OCT-4--and are characterized by higher resistance to chemotherapy. The simultaneous positivity for thyroid specific factor TTF-1 and onfFN suggest

    The effect of 17-allylamino-17-demethoxygeldanamycin (17-AAG), an hsp90 inhibitor, alone or in combination with paclitaxel on survival of anaplastic thyroid carcinoma (ATC) was evaluated. In 8505C and CAL62 cells, after treatment of 17-AAG, cell viability decreased, and the percentage of dead cells increased. 17-AAG did not cause cleavage of caspase-3 protein, and change expression of IAPs. Pretreatment of z-VAD-fmk did not alter cell viability and the percentage of dead cells. In 17-AAG-treated cells, knockdown of p53 rescued growth inhibition, while cycloheximide attenuated cell death. When cells were treated with both 17-AAG and paclitaxel, all of the combination index values were higher than 1, indicating antagonism between 17-AAG and paclitaxel. In 17-AAG- and paclitaxel-treated cells, compared with paclitaxel alone-treated cells, the protein levels of hsp90, hsp70, and hsc70 increased. In conclusion, our results suggest that 17-AAG induces non-apoptotic cell death requiring de novo protein synthesis in ATC cells. Moreover, these results demonstrate that 17-AAG antagonizes paclitaxel with concomitant alterations in hsp90 client proteins in ATC cells. PMID:25096912

    Medullary thyroid cancer is the neuroendocrine tumor (NET) of thyroid with mostly both secreting calcitonin and immunohistochemically showing calcitonin positivity. Occasionally; NETs of thyroid may have little or no calcitonin expression. We present a case of serum calcitonin negative and immunohistochemically calcitonin-negative staining tumor with positive reaction to neuroendocrine markers synaptophysin and chromogranin-A. The patient’s right vocal cord was paralytic and thyroid mass was huge with descending to thorax till hilar region. We discussed diagnostic difficulties and way of treatment about NETs of thyroid with the light of current literature with this case. PMID:26312221

    MicroRNAs (miRNAs) play important roles in the pathogenesis of many types of cancers by negatively regulating gene expression at posttranscriptional level. However, the role of microRNAs in anaplastic thyroid carcinoma (ATC), has remained elusive. Here, we identified that miR-4295 promotes ATC cell proliferation by negatively regulates its target gene CDKN1A. In ATC cell lines, CCK-8 proliferation assay indicated that the cell proliferation was promoted by miR-4295, while miR-4295 inhibitor significantly inhibited the cell proliferation. Transwell assay showed that miR-4295 mimics significantly promoted the migration and invasion of ATC cells, whereas miR-4295 inhibitors significantly reduced cell migration and invasion. luciferase assays confirmed that miR-4295 directly bound to the 3'untranslated region of CDKN1A, and western blotting showed that miR-4295 suppressed the expression of CDKN1A at the protein levels. This study indicated that miR-4295 negatively regulates CDKN1A and promotes proliferation and invasion of ATC cell lines. Thus, miR-4295 may represent a potential therapeutic target for ATC intervention. - Highlights: • miR-4295 mimics promote the proliferation and invasion of ATC cells. • miR-4295 inhibitors inhibit the proliferation and invasion of ATC cells. • miR-4295 targets 3′UTR of CDKN1A in ATC cells. • miR-4295 negatively regulates CDKN1A in ATC cells.

  18. Successful radiation treatment of anaplastic thyroid carcinoma metastatic to the right cardiac atrium and ventricle in a pacemaker-dependent patient

    International Nuclear Information System (INIS)

    Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy, which is known to metastasize to the heart. We report a case of a patient with ATC with metastatic involvement of the pacemaker leads within the right atrium and right ventricle. The patient survived external beam radiation treatment to his heart, with a radiographic response to treatment. Cardiac metastases are usually reported on autopsy; to our knowledge, this is the first report of the successful treatment of cardiac metastases encasing the leads of a pacemaker, and of cardiac metastases from ATCs, with a review of the pertinent literature

    The influence of the heat shock protein 90 (hsp90) inhibitor SNX5422 alone or in combination with the histone deacetylase (HDAC) inhibitors PXD101, suberoylanilide hydroxamic acid (SAHA), and trichostatin A (TSA) on survival of anaplastic thyroid carcinoma (ATC) cells was investigated. In 8505C and CAL62 cells, SNX5422 caused cell death with concomitant changes in the expression of hsp90 client proteins. After treatment of both SNX5422 and PXD101, SAHA and TSA, compared with treatment of SNX5422 alone, cell viability was diminished, whereas inhibition rate and cytotoxic activity were enhanced. All of the combination index values were lower than 1.0, suggesting the synergism between SNX5422 and PXD101, SAHA and TSA in induction of cell death. In cells treated with both SNX5422 and PXD101, SAHA and TSA, compared with cells treated with SNX5422 alone, the protein levels of Akt, phospho-4EBP1, phospho-S6 K, and survivin were diminished, while those of γH2AX, acetyl. histone H3, acetyl. histone H4, cleaved PARP, and cleaved caspase-3 were enhanced. In conclusion, these results demonstrate that SNX5422 has a cytotoxic activity in conjunction with alterations in the expression of hsp90 client proteins in ATC cells. Moreover, SNX5422 synergizes with HDAC inhibitors in induction of cytotoxicity accompanied by the suppression of PI3K/Akt/mTOR signaling and survivin, and the overexpression of DNA damage-related proteins in ATC cells.

    Full Text Available It has been suggested that cancer stem cells (CSC may play a central role in oncogenesis, especially in undifferentiated tumours. Anaplastic thyroid carcinoma (ATC has characteristics suggestive of a tumour enriched in CSC. Previous studies suggested that the stem cell factor SOX2 has a preeminent hierarchical role in determining the characteristics of stem cells in SW1736 ATC cell line. In detail, silencing SOX2 in SW1736 is able to suppress the expression of the stem markers analysed, strongly sensitizing the line to treatment with chemotherapeutic agents. Therefore, in order to further investigate the role of SOX2 in ATC, a competing endogenous RNA (ceRNA analysis was conducted in order to isolate new functional partners of SOX2. Among the interactors, of particular interest are genes involved in the biogenesis of miRNAs (DICER1, RNASEN, and EIF2C2, in the control cell cycle (TP53, CCND1, and in mitochondrial activity (COX8A. The data suggest that stemness, microRNA biogenesis and functions, p53 regulatory network, cyclin D1, and cell cycle control, together with mitochondrial activity, might be coregulated.

    Anaplastic thyroid cancer is one of the most aggressive human malignancies and is resistant to multimodal treatments. The expression of h-prune, the human homologue of Drosophila prune, has been reported to be correlated with progression and aggressiveness in various cancers including breast, colorectal and pancreatic cancers. We examined the role of h-prune in anaplastic thyroid cancer cell migration, invasion and metastasis. Immunohistochemical analysis of h-prune was performed with 15 surgically resected specimens of anaplastic thyroid cancers. To investigate cell motility, Boyden chamber, wound healing and matrigel invasion assays were performed using cells from anaplastic thyroid cancer cell lines. A murine orthotopic thyroid cancer model was used to investigate metastatic ability. In the immunohistochemical analysis, only weak focal or no staining of h-prune was observed in non-tumor tissue. In contrast, diffuse staining of h-prune was observed in anaplastic thyroid cancer and lymph node metastasis samples. Both inhibition of h-prune phosphodiesterase activity with dipyridamole and small interfering RNA for h-prune suppressed 8505C and KTC-3 cell motility. In addition, treatment with dipyridamole and decreased expression of h-prune suppressed tumor invasion and pulmonary metastasis in a NOD/Shi-scid, IL-2Rγnull (NOG) mouse orthotopic thyroid cancer model. In conclusion, h-prune is frequently expressed in anaplastic thyroid cancer cells and lymph nodes metastasis, and promotes migration and invasion of anaplastic thyroid cancer cells and metastasis in an anaplastic thyroid cancer model. Thus, h-prune shows promise as a targeting candidate against anaplastic thyroid cancer. PMID:27109060

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

    Primary anaplastic carcinoma is a rare variant of small intestinal cancer. Most reports of primary anaplastic carcinoma of the small intestine are isolated case reports, therefore the clinicopathological features, therapeutic management, and surgical outcome of this tumor type remain unclear. This review analyzes the available clinical characteristics of primary anaplastic carcinoma of the small intestine and investigates key differences from differentiated adenocarcinoma of the small intestine. A Medline search was performed using the keywords 'small intestine' and 'anaplastic carcinoma' or 'undifferentiated carcinoma'. Additional articles were obtained from references with in the papers identified by the Medline search. The literature revealed a poor prognosis for patients who underwent surgical resection for anaplastic carcinoma of the small intestine, which gave a 3-year overall survival rate of 10.8% and a median survival time of 5.0 mo. The literature suggests that anaplastic carcinoma is markedly more aggressive than differentiated adenocarcinoma of the small intestine. Surgical resection with the aim of complete tumor removal provides the only beneficial therapeutic option for patients with anaplastic carcinoma of the small intestine, because chemotherapy and radiation therapy have no significant effect on the rate of survival. However, despite complete tumor resection, most patients with anaplastic carcinoma of the small intestine are at great risk of disease recurrence. Multicenter clinical trials are expected to provide additional therapeutic strategies and establish the efficacy of multimodality adjuvant therapy. This report also highlights the importance of a systematic diagnostic approach for anaplastic carcinoma of the small intestine.

To improve safety and efficiency of small interfering RNA (siRNA delivery, a triblock dendritic nanocarrier, polyamidoamine-polyethylene glycol-cyclic RGD (PAMAM-PEG-cRGD, was developed and studied as an siRNA vector targeting the human ether-à-go-go-related gene (hERG in human anaplastic thyroid carcinoma cells. Structure characterization, particle size, zeta potential, and gel retardation assay confirmed that complete triblock components were successfully synthesized with effective binding capacity of siRNA in this triblock nanocarrier. Cytotoxicity data indicated that conjugation of PEG significantly alleviated cytotoxicity when compared with unmodified PAMAM. PAMAM-PEG-cRGD exerted potent siRNA cellular internalization in which transfection efficiency measured by flow cytometry was up to 68% when the charge ratio (N/P ratio was 3.5. Ligand-receptor affinity together with electrostatic interaction should be involved in the nano-siRNA endocytosis mechanism and we then proved that attachment of cRGD enhanced cellular uptake via RGD-integrin recognition. Gene silencing was evaluated by reverse transcription polymerase chain reaction and PAMAM-PEG-cRGD-siRNA complex downregulated the expression of hERG to 26.3% of the control value. Furthermore, gene knockdown of hERG elicited growth suppression as well as activated apoptosis by means of abolishing vascular endothelial growth factor secretion and triggering caspase-3 cascade in anaplastic thyroid carcinoma cells. Our study demonstrates that this novel triblock polymer, PAMAM-PEG-cRGD, exhibits negligible

    Low-level laser therapy (LLLT) is a non-thermal phototherapy used in several medical applications, including wound healing, reduction of pain and amelioration of oral mucositis. Nevertheless, the effects of LLLT upon cancer or dysplastic cells have been so far poorly studied. Here we report that the effects of laser irradiation on anaplastic thyroid cancer cells leads to hyperplasia. 650nm of laser diode was performed with a different time interval (0, 15, 30, 60J/cm2 , 25mW) on anaplastic thyroid cancer cell line FRO in vivo. FRO was orthotopically injected into the thyroid gland of nude mice and the irradiation was performed with the same method described previously. After irradiation, the xenograft evaluation was followed for one month. The thyroid tissues from sacrificed mice were undergone to H&E staining and immunohistochemical staining with HIF-1α, Akt, TGF-β1. We found the aggressive proliferation of FRO on thyroid gland with dose dependent. In case of 60 J/ cm2 of energy density, the necrotic bodies were found in a center of the thyroid. The phosphorylation of HIF-1α and Akt was detected in the thyroid gland, which explained the survival signaling of anaplastic cancer cell was turned on the thyroid gland. Furthermore, TGF-β1 expression was decreased after irradiation. In this study, we demonstrated that insufficient energy density irradiation occurred the decreasing of TGF-β1 which corresponding to the phosphorylation of Akt/ HIF-1α. This aggressive proliferation resulted to the hypoxic condition of tissue for angiogenesis. We suggest that LLLT may influence to cancer aggressiveness associated with a decrease in TGF-β1 and increase in Akt/HIF-1α.

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

    Anaplastic thyroid cancer (ATC) is a rare malignancy. While external beam radiation therapy has improved locoregional control, the median survival of ∼ 4 months has not changed in more than half a century due to uncontrolled systemic metastases. The objective of this study was to review the literature in order to identify potential new strategies for treating this highly lethal cancer. PubMed searches were the principal source of articles reviewed. The molecular pathogenesis of ATC includes m...

    BACKGROUND The transforming growth factor-beta (TGF-β) signaling pathway plays a critical role in promoting tumor growth. TGF-β1was found to be overexpressed in anaplastic thyroid cancer (ATC). We therefore tested our hypothesis that targeting TGF-β1 inhibits tumorigenesis of ATC cells. MATERIAL AND METHODS Effects of TGF-β1 stimulation or TGF-β1 inhibition by small interfering RNA (TGF-β1siRNA) on proliferation, colony formation, and apoptosis in 8505C cells in vitro was detected using siRNAs and inhibitors to examine the TGF-β1 signaling pathway. A subcutaneously implanted tumor model of 8505C cells in nude mice was used to assess the effects of TGF-β1 inhibition on tumorigenesis development. RESULTS TGF-β1siRNAs decreased proliferation and colony formation, and increased apoptosis in 8505C cells in vitro and inhibited tumor growth in vivo. TGF-β1siRNA inhibited phosphorylation ERK1/2 (pERK1/2) and increased p65-dependant PUMA mRNA and protein expression. Knockdown of p65 or PUMA by siRNA reduced TGF-β1siRNA-induced apoptosis, as well as caspase-3 and PARP activation. Upregulation of p65 or PUMA expression by TGF-β1siRNA requires pERK1/2 inhibition. TGF-β1 shRNA inhibited tumor growth in vivo. CONCLUSIONS Therapies targeting the TGF-β1 pathway may be more effective to prevent primary tumor formation. The ability of this therapy to decrease tumorigenesis may be related to ERK1/2/NF-κB/PUMA signaling. PMID:27356491

    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.

  4. Diagnosis and management of carcinoma of the thyroid

    International Nuclear Information System (INIS)

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

    Anaplastic thyroid cancer (ATC) is one of the most aggressive human malignancies, with no effective treatment currently available. Previously, we identified agents active against ATC cells, both in vitro and in vivo, using quantitative high-throughput screening of 3282 clinically approved drugs and small molecules. Here, we report that combining two of these active agents, carfilzomib, a second-generation proteasome inhibitor, and CUDC-101, a histone deacetylase and multi-kinase inhibitor, results in increased, synergistic activity in ATC cells. The combination of carfilzomib and CUDC-101 synergistically inhibited cellular proliferation and caused cell death in multiple ATC cell lines harboring various driver mutations observed in human ATC tumors. This increased anti-ATC effect was associated with a synergistically enhanced G2/M cell cycle arrest and increased caspase 3/7 activity induced by the drug combination. Mechanistically, treatment with carfilzomib and CUDC-101 increased p21 expression and poly (ADP-ribose) polymerase protein cleavage. Our results suggest that combining carfilzomib and CUDC-101 would offer an effective therapeutic strategy to treat ATC. PMID:26934320

    Full Text Available Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic and therapeutic significance, relatively little about insular carcinoma has been published in the otolaryngology literature. In this article, we discuss a case of insular carcinoma of thyroid presenting with concurrent distant metastasis to skull, lung, ribs, and inguinal region with review of the literature. We conclude that insular thyroid carcinoma warrants aggressive management with total thyroidectomy and excision of accessible giant lesion followed by radioactive iodine ablation of any remaining thyroid tissue.

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.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

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.

    Full Text Available Abstract Background Secondary involvement of the thyroid gland by malignant metastases is uncommon. Acute respiratory crisis due to infiltration of the upper airways is a recognised complication of anaplastic thyroid carcinoma or thyroid lymphoma. Renal cell carcinoma is a tumour that metastasizes diffusely and in an unpredictable manner. Case presentation We report a case of a 73-year-old man with a painful neck mass, dyspnoea, stridor and dysphonia that was evaluated in emergency. A right radical nephrectomy for renal cell carcinoma was performed 8 years previously. An emergency endotracheal intubation was followed by total thyroidectomy. Histological examination confirmed the diagnosis of thyroid metastasis from renal cell carcinoma. Conclusion A literature review regarding emergency treatment for acute respiratory compromise resulting from secondary thyroid tumours was undertaken. Only two cases of metastatic colon cancer and one case of metastatic meningioma requiring emergency thyroidectomy for acute respiratory failure are reported in the literature. This appears to be the first case of emergency surgery performed for acute respiratory compromise due to thyroid metastasis from renal cell carcinoma.

    Full Text Available Introduction. Mixed medullary-follicular thyroid carcinoma is an uncommon tumor that consists of both follicular and parafollicular cells. Case. We report a 43-year-old woman with a palpable mass in the right side of the neck. Fine needle aspiration suggested a diagnosis of high grade anaplastic carcinoma that has been associated with papillary features. Total thyroidectomy was done in which histopathological examination showed diagnosis of medullary carcinoma. Immunohistochemical staining was positive for chromogranin, calcitonin, and thyroglobulin in tumoral cells. Conclusion. Mixed medullary-follicular thyroid carcinoma is a rare tumor. Diagnosis of these tumors with fine needle aspiration is very difficult and may lead to misdiagnosis. It is necessary to correlate the cytological finding with serum calcitonin and thyroglobulin. Also immunostaining for calcitonin and thyroglobulin confirms diagnosis.

    Full Text Available We report the immunohistochemical diagnosis, including TTF-1 (thyroid transcription factor 1 and Ki-67, of a rare mixed thyroid neoplasm composed of minimally invasive well differentiated follicular areas and highly aggressive undifferentiated anaplastic areas. A 75 old female presented to our clinic with a rapidly growing neck mass. Considering the dynamics of the disease and the multiple challenges presented by the patient: advanced age, tumor size, history of a longstanding goiter we decided to transfer her to the department of surgery. The intraoperative findings were an enlarged right lobe with tracheal and surrounding tissues infiltration. Total thyroidectomy, radical neck lymph nodes dissection and tracheostomy were performed. The histopathological and immunohistochemical examination revealed a coexistent anaplastic and follicular thyroid carcinoma. The proliferation index Ki-67, a cell proliferation marker, was found to be significantly higher in the anaplastic areas (30 +/- 5% in the comparison with the follicular areas (2 +/- 1%. The evaluation of the thyroid transcription factor 1 (TTF-1 expression revealed a correlation with the tumor cells aggressiveness accordingly to the cancer areas. After a radical surgery an external adjuvant radiation was applied. The patient is alive and more than five years after diagnosis she presented an increase of the serum thyroglobulin level suggesting, probably, a recurrence of the follicular form of the cancer. According to our survey we suggest that in thyroid cancers TTF-1 and Ki-67 could provides useful information on the differentiation activities of thyroid tumor cells and may be helpful to distinguish well differentiated and undifferentiated areas in a mixed thyroid cancer.

    International Nuclear Information System (INIS)

    The incidence of thyroid carcinoma increases significantly following exposure to ionizing irradiation. However, the mechanisms of radiation-induced tumorigenesis at the molecular and chromosomal levels have not been identified. In order to gain some indication of the processes affecting the thyroid epithelium, cytogenetic and molecular genetic investigations were performed on childhood thyroid carcinomas that developed after the Chernobyl nuclear accident in Belarussia, and on secondary thyroid tumours that developed after radiotherapy. At the cytogenetic level, the radiation-induced tumours were shown to have an increased frequency of translocations, multiple and complex chromosome aberrations, and novel breakpoints for structural chromosome aberrations. At the molecular level, different alterations of the RET protooncogene were detected in 65% of the Belarussian tumours. (orig.)

    Our aim was to evaluate in anaplastic thyroid carcinoma (ATC) patients the value of {sup 18}F-FDG PET/CT compared with total body computed tomography (CT) using intravenous contrast material for initial staging, prognostic assessment, therapeutic monitoring and follow-up. Twenty consecutive ATC patients underwent PET/CT for initial staging. PET/CT was performed again during follow-up. The gold standard was progression on imaging follow-up (CT or PET/CT) or confirmation with another imaging modality. A total of 265 lesions in 63 organs were depicted in 18 patients. Thirty-five per cent of involved organs were demonstrated only with PET/CT and one involved organ only with CT. In three patients, the extent of disease was significantly changed with PET/CT that demonstrated unknown metastases. Initial treatment modalities were modified by PET/CT findings in 25% of cases. The volume of FDG uptake ({>=}300 ml) and the intensity of FDG uptake (SUV{sub max} {>=}18) were significant prognostic factors for survival. PET/CT permitted an earlier assessment of tumour response to treatment than CT in 4 of the 11 patients in whom both examinations were performed. After treatment with combined radiotherapy and chemotherapy, only the two patients with a negative control PET/CT had a confirmed complete remission at 14 and 38 months; all eight patients who had persistent FDG uptake during treatment had a clinical recurrence and died. FDG PET/CT appears to be the reference imaging modality for ATC at initial staging and seems promising in the early evaluation of treatment response and follow-up. (orig.)

  1. CT diagnosis of thyroid carcinoma

    International Nuclear Information System (INIS)

    Purpose: To study the CT appearances of thyroid carcinoma and its cervical metastatic lymphadenopathy, as well as to evaluate the diagnostic criteria of tumor invasion of adjacent structures. Methods: CT findings of surgery and pathology proved thyroid carcinoma in 52 patients were analyzed. Results: All of the primary tumor were heterogeneous in density, 32 tumors (82.5%) were ill-defined. Fine granular calcifications were revealed in 11 primary tumors and metastatic lymph nodes in 5 cases. Cystic formation with intracystic high density papillary-like nodules were found in 4 primary tumors and metastatic lymphadenopathy in 5 cases. Trachea, esophagus and carotic artery invasion were proved by surgery in 22, 21 and 10 cases respectively. Serrated inner wall and tumor nodule protrusion into tracheal lumen were the definite signs of trachea invasion. Use tumor encasement over 1/2 of the circumference of esophagus and 1/3 of the circumference of carotid artery as the diagnostic criterion of invasion, sensitivity was 71.4%, 100.0% specificity was 96.3%, 95.2% respectively. Conclusion: Fine granular calcification and cystic formation with high attenuation intracystic papillary-like nodules were characteristic manifestations of primary thyroid carcinoma (especially papillary carcinoma) and its metastatic lymphadenopathy as well. Contrast enhanced CT scan is helpful in the diagnosis of thyroid carcinoma and the delineation of tumor extent, which is very important in surgical planning

    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.

    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 S...

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

    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 < 0.05), and TSH level was significantly increased (P < 0.05). After RFA, radioiodine concentration in the ablation area was significantly reduced in the majority of patients. The reduction rate of thyroid update was 0.69±0.20%. DTC staging and interval between surgery and RFA had negative correlation (Pearson coefficient = -0.543; P = 0.001), with no obvious correlation among others influential factors. RFA is an effective and safe method for postsurgical thyroid removal of DTC. PMID:27186311

  16. Thyroid hormone therapy following the thyroidectomy for thyroid carcinoma

    International Nuclear Information System (INIS)

    Medication with thyroid hormones following total thyroidectomy for thyroid carcinoma is based on the following principles: 1. The patient is informed about the lifelong necessity of taking a thyroid hormones daily before breakfast. This hormone must be given orally and its bioligical effect is identical with that of the tyhroid hormone secreted by the healthy thyroid gland. 2. The daily dosage of thyroid hormones may be assessed on the basis of the following parameters: a) the patient's clinical euthyroidism, b) suppression of thyrotropic activity, c) unrestricted tolerance of the preparation. 3. The in vitro parameters associated with optimal medication should be within the following ranges: Thyroxine value (TT4 or FT4): above the normal range, triiodothyronine value (TT3 or FT3): within the upper normal range and thyrotropin value (TSH 'ultrasensitive' or TRH-test): suppressed.

  17. Solid variant of papillary carcinoma thyroid in a child with no history of radiation exposure

    International Nuclear Information System (INIS)

    Solid variant is a rare and poorly characterized variant of papillary thyroid carcinoma (PTC) and comprises approximately 3% of PTCs. It is more common in children and has high propensity for extrathyroidal metastasis. It is seen in higher proportion in post-radiation PTCs and has been seen in more than one-third of post Chernobyl radiation induced PTCs in some studies. It usually presents with differential diagnosis of poorly differentiated carcinoma versus anaplastic versus medullary thyroid carcinoma versus metastasis from extrathyroidal malignancy on fine needle aspiration cytology. This report describes a case of solid variant of PTC in a child who had no history of radiation exposure and shows the importance to be given to histopathology when the pre-operative diagnosis is not clear.

  19. Management of small-cell anaplastic carcinoma, 1980-1982

    International Nuclear Information System (INIS)

    The author gives an updated report on the management of small-cell carcinoma of the lung, particularly on staging and therapy. He presents and discusses data accumulated from the literature published in 1980 and 1981 and finishes with 9 conclusions regarding treatment of these carcinomas. Of interest are the following: combined use of chemotherapy and radiotherapy is clearly superior to radiotherapy alone; prophylactic brain irradiation decreases the incidence of brain metastases, but it does not change the overall median survival. It should probably be restricted to patients who have achieved complete remission; radiotherapy to the primary tumor and including the regional lymph nodes decreases the rate of local recurrence, but it does not influence the median survival when given with combination chemotherapy. The morbidity of the combined modality of therapy is considerably higher than when using chemotherapy alone. Whether the percentage of long-term remission survivors is higher when the combined modality of therapy is used, is still uncertain. (C.F.)

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

  1. Dosimetric comparison between helical tomotherapy and volumetric modulated arc-therapy for non-anaplastic thyroid cancer treatment

    International Nuclear Information System (INIS)

    To evaluate and compare dosimetric parameters of volumetric modulated arctherapy (VMAT) and helical tomotherapy (HT) for non-anaplastic thyroid cancer adjuvant radiotherapy. Twelve patients with non-anaplastic thyroid cancer at high risk of local relapse received adjuvant external beam radiotherapy with curative intent in our institution, using a two-dose level prescription with a simultaneous integrated boost approach. Each patient was re-planned by the same physicist twice using both VMAT and HT. Several dosimetric quality indexes were used: target coverage index (proportion of the target volume covered by the reference isodose), healthy tissue conformity index (proportion of the reference isodose volume including the target volume), conformation number (combining both previous indexes), Dice Similarity Coefficient (DSC), and homogeneity index ((D2%-D98%)/prescribed dose). Dose-volume histogram statistics were also compared. HT provided statistically better target coverage index and homogeneity index for low risk PTV in comparison with VMAT (respectively 0.99 vs. 0.97 (p = 0.008) and 0.22 vs. 0.25 (p = 0.016)). However, HT provided poorer results for healthy tissue conformity index, conformation number and DSC with low risk and high risk PTV. As regards organs at risk sparing, by comparison with VMAT, HT statistically decreased the D2% to medullary canal (25.3 Gy vs. 32.6 Gy (p = 0.003)). Besides, HT allowed a slight sparing dose for the controlateral parotid (Dmean: 4.3 Gy vs. 6.6 Gy (p = 0.032)) and for the controlateral sub-maxillary gland (Dmean: 29.1 Gy vs. 33.1 Gy (p = 0.041)). Both VMAT and HT techniques for adjuvant treatment of non-anaplastic thyroid cancer provide globally attractive treatment plans with slight dosimetric differences. However, helical tomotherapy clearly provides a benefit in term of medullary canal sparing

    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.

    Introduction. Anaplastic thyroid carcinoma (ATC) is rare yet accounts for up to 50% of all thyroid cancer deaths. This study reviews outcomes of patients with confirmed ATC referred to a tertiary oncology centre plus reviews the literature to explore how poor outcomes may be improved. Materials and Methods. The management and outcomes of 20 patients with ATC were reviewed. Results. Median age at diagnosis was 69.5 years. 19 patients died due to ATC, 40% of whom died from asphyxiation. Median survival for all cases was 59 days. Patients who had previous surgery prior to other treatment modalities had a longer median survival overall compared to those who had not had previous surgery (142 days compared to 59 days) and produced the one long-term survivor. Chemotherapy followed by radiotherapy (without previous surgery) was associated with longer median survival (220 days). Palliative radiotherapy alone did not decrease the rate of death by asphyxiation when compared to other single modality treatments. Conclusion. Multimodality treatment including surgery when feasible remains the best strategy to improve survival and prevent death from asphyxiation in the management of ATC. The addition of chemotherapy to our institutional protocol led to improved survival but prognosis remains very poor. PMID:25184150

    CD30+ lymphoproliferative disorders (LPD) represent a spectrum of T-cell lymphoma including lymphomatoid papulosis and anaplastic large cell lymphoma (ALCL). Epidermis overlying cutaneous CD30+ LPD often shows epidermal hyperplasia, hyperkeratosis, crusting, and ulceration and it is difficult to distinguish from carcinoma such as keratoacanthoma (KA) or squamous cell carcinoma (SCC). Several cases of pseudocarcinomatous hyperplasia mimicking KA or SCC in CD30+ LPD have been reported. The relationship between CD30+ LPD and epithelial proliferations has not yet well understood. It was reported that a variety of mediators, including epidermal growth factor (EGF), transforming growth factor-α and EGFR from CD30+ LPD could attribute to epidermal hyperplasia. However, separate and distinct SCC occurring in CD30+ LPD has rarely been reported. Herein, we present a rare case of coexistence of SCC and cutaneous ALCL located on the same region. PMID:27489433

    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.

  11. Multidisciplinaly total-cell-kill treatment of bronchogenic small cell anaplastic carcinoma

    International Nuclear Information System (INIS)

    Survival time of the patients with bronchogenic small cell anaplastic cancer was studied. Combined treatment with six-drug combination chemotherapy ''METVFC'' (mitomycin C + cyclophosphamide + toyomycin + vincristine + 5-FU + cytosine arabinoside) and radiotherapy (5,000 rads in total) was given to 14 cases of limited disease of small cell carcinoma. Median survival was 8 months, one year and two year survival rates were 47% and 27%, respectively. Combined treatment with METVFC and small dose radiotherapy of 100 or 200 rads irradiation 4 hours before chemotherapy, followed by remission consolidation of 3,000 -- 4,000 rads radiotherapy, thereafter second line chemotherapy of ''COAM'' (cyclophosphamide + vincristine + ACNU + methotrexate) was given to 4 cases of limited disease of small cell carcinoma. All cases survived more than 1.5 years and two of them have retained complete remission more than 1.5 years. There are 6 cases with small cell carcinoma survived more than 3 years out of total 128 cases. They are all those of limited disease. They received combined treatment of chemotherapy and radiotherapy simultaneously or alternatively, followed by remission maintenance chemotherapy. One case of them died from cancer. Two cases died from another disease without lung cancer. Three cases survived healthy more than 3 to 8 years. In the limited disease, small cell carcinoma of the lung might be curable if the complete remission could continue more than three years. (author)

  12. CT features of small thyroid carcinoma

    International Nuclear Information System (INIS)

    Objective: To study the CT findings of small thyroid carcinoma. Methods: The CT findings of 40 patients with histology-proven small thyroid carcinoma (diameter, 1.0 to 2.0 cm) were retrospectively reviewed. Results: (1) The single lesion was detected in 38 cases and two lesions in bilateral thyroid in 2 cases. Two cases were combined with contralateral nodular goiter and 1 case with contralateral thyroid adenoma. (2) Eight lesions showed smooth edge and complete envelope. Thirty-four lesions demonstrated foggy edge and incomplete envelope, but they didn't invade the surrounding soft tissues and important organs. (3) The density of' all lesions were homogeneous or comparatively homogeneous without obvious hemorrhage or necrosis area on non-enhanced CT. Thirty lesions showed varied shape calcifications, with granular calcifications in 20 lesions being the most common. Irregular nodular, eggshell-like or mulberry-like calcifications were also detected. (4) Forty-one lesions showed marked enhancement on post-contrast CT and the amplitude of enhanced CT value was greater than 40 HU (range, 90 to 140 HU). Thirty-eight lesions exhibited homogeneous enhancement, and other 3 lesions showed marked enhancement center with a ring-like low density edge and manifested as a characteristic damascene-like appearance. (5) Enlarged cervical lymph nodes were found in 24 cases (60.0%), which displayed solid, cystic-solid or cystic appearances on non- enhanced CT. They showed markedly homogeneous, irregular ring or wall-node enhancement on post-contrast CT. In 8 cases there were granular, nodular or eggshell-like calcifications within the enlarged lymph nodes. Conclusion: A solid thyroid nodule with granular calcification, incomplete envelope and marked enhancement, accompanied with enlarged lymph nodes with calcification, cystic degeneration and obviously enhanced solid part are the relatively characteristic CT features of small thyroid carcinoma.

  13. Post surgical management protocol for thyroid carcinoma

    International Nuclear Information System (INIS)

    Objectives: The objectives of a management protocol for thyroid carcinoma are to increase five and 10 year survival rate and to give the patients a long uncomplicated life. Certain prognostic factors determine the outcome of the disease. These factors generally help in selection of high risk group that require more aggressive treatment and follow up from the low risk group that are managed in a more conservative way. The different factors that determine prognosis are: the age of the patient, gender, tumour size, presence of extra thyroid extension, distant metastasis, histologic grading of the tumor, tumor staging, family history and oncogenicity, time of treatment after initial diagnosis etc. (Author)

    Full Text Available Metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. Breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. Metastasis from thyroid gland is extremely rare to oral region. We present an unusual case of metastatic follicular carcinoma of thyroid in maxilla. The significance of this report is that the secondary lesion was the only symptom of the primary tumor and helped us in diagnosis and treatment of disease.

  15. Small cell anaplastic carcinoma of primary lung tumor in a miniature schnauzer dog

    International Nuclear Information System (INIS)

    A seven-year-old male, an intact miniature Schnauzer dog with history of vomiting, abdominal distention, anorexia, and dyspnea was referred for further evaluation and treatment. Thoracic radiographs showed the well marginated solitary mass with soft density in the right caudal lung field, and abdominal radiographs showed signs of ascites, such as abdominal distention and moderate serosal detail loss. On ultrasonograph and computed tomograph, it was observed that the mass compressed the caudal vena cava (CVC) and adhered to the heart. Exploratory thoracotomy was performed, and then it was showed that mass adhered heart, CVC, and diaphragm. The mass was fully rejected although adhered part of CVC could not be completely rejected. On histopathological findings, the mass was diagnosed as small-cell anaplastic carcinoma

  16. CT manifestations of lymph node metastasis of thyroid carcinoma

    International Nuclear Information System (INIS)

    Objective: to study the CT manifestations of metastatic lymph node of thyroid carcinoma. Methods: CT appearances of metastatic lymph node of thyroid carcinoma proved by surgery and pathology in 108 patients were reviewed. Results: Of these 108 cases, metastatic lymph node were located at superior and middle internal jugular chain (n = 76), inferior internal jugular chain and super clavicular region (n = 86), tracheoesophageal groove (n = 52), and superior mediastinum (n = 17). Of 84 thyroid papillary carcinoma patients, the attenuation of metastatic lymph nodes were similar to that of normal thyroid gland (n = 16), with cystic formations, (n = 24), intra-cystic high attenuation papillary-like nodules (n = 18), and fine granular calcifications (n = 11). Of 24 follicular carcinoma, medullary carcinoma, and clear cell carcinoma patients, 17 cases had significant homogeneous or heterogeneous enhanced nodes, and the attenuation was the same as primary or recurrent thyroid tumors. Conclusion: For thyroid carcinoma, the most common locations of metastatic lymph nodes were internal jugular chain, tracheoesophageal groove, and superior mediastinum regions. Marked enhancement similar to normal thyroid gland, cystic formations with intra-cystic high attenuation papillary-like nodules, and fine discrete granular calcifications were the characteristic manifestations of metastatic lymph node of papillary carcinoma. Marked homogeneous or heterogeneous enhancement after contrast administration and the same attenuation as the primary or recurrent thyroid tumor were found in follicular carcinoma, medullary carcinoma, and clear cell carcinoma metastases

    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.

  19. Differentiated thyroid carcinomas in children and adolescents

    International Nuclear Information System (INIS)

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

    Full Text Available A 68-year-old woman with solid/trabecular follicular thyroid carcinoma inside of an autonomously functioning thyroid nodule is described in this paper. The patient was referred to our clinic for swelling of the neck and an increased pulse rate. Ultrasonography showed a slightly hypoechoic nodule in the right lobe of the thyroid. Despite suppressed TSH levels, the 99mTc-pertechnetate scan showed a hot area corresponding to the nodule with a suppressed uptake in the remaining thyroid tissue. Histopathological examination of the nodule revealed a solid/trabecular follicular thyroid carcinoma. To the best of our knowledge, this is the first case of hyperfunctioning follicular solid/trabecular carcinoma reported in the literature. Even if a hyperfunctioning thyroid carcinoma is an extremely rare malignancy, careful management is recommended so that a malignancy will not be overlooked in the hot thyroid nodules.

    Full Text Available Anaplastic thyroid carcinoma (ATC is one of the most deadly cancers. With intensive multimodalities of treatment, the survival remains low. ATC is not sensitive to 131I therapy due to loss of sodium iodide symporter (NIS gene expression. We have previously generated a stable human NIS-expressing ATC cell line, ARO, and the ability of iodide accumulation was restored. To make NIS-mediated gene therapy more applicable, this study aimed to establish a lentiviral system for transferring hNIS gene to cells and to evaluate the efficacy of in vitro and in vivo radioiodide accumulation for imaging and therapy. Lentivirus containing hNIS cDNA were produced to transduce ARO cells which do not concentrate iodide. Gene expression, cell function, radioiodide imaging and treatment were evaluated in vitro and in vivo. Results showed that the transduced cells were restored to express hNIS and accumulated higher amount of radioiodide than parental cells. Therapeutic dose of 131I effectively inhibited the tumor growth derived from transduced cells as compared to saline-treated mice. Our results suggest that the lentiviral system efficiently transferred and expressed hNIS gene in ATC cells. The transduced cells showed a promising result of tumor imaging and therapy.

    Full Text Available Anaplastic carcinoma (AC or undifferentiated carcinoma of the pancreas is a rare variant among the malignant pancreatic neoplasms. These tumors have a poor prognosis with survival measured in months. The role of surgical palliation to improve the quality of life is not well defined in these patients. We report a case of AC of pancreas in a 65-year-old male patient. Patient had upper abdominal pain with frequent bilious vomiting. Computed tomography scan of the abdomen showed a mass in the body of pancreas with possible infiltration of duodenojejunal flexure (DJF. Laparotomy revealed an inoperable mass with posterior fixity and involvement of the DJF. Patient underwent a palliative duodenojejunostomy. Tissue biopsy from the tumor showed pleomorphic type AC with giant cells. Patient had good symptomatic relief from profuse vomiting and progressed well at follow up. AC of pancreas is a rare and aggressive malignancy with dismal outlook. If obstructive symptoms are present due to duodenal involvement, a palliative bypass may be a worthwhile surgical option in selected cases.

    Flow-cytometric DNA analysis yields information on ploidy and proliferative characteristics of a cell population. The analysis was implemented on small-cell anaplastic carcinoma of the lung using a rapid detergent technique for the preparation of fine-needle aspirates for DNA determination and a...... newly developed procedure for storing aspirates at -80 degrees. Thirty-eight different metastases in 30 consecutive patients with small-cell anaplastic carcinoma of the lung were examined with a total of 273 fine-needle aspirations. The results on ploidy are reported in this paper. The degree of...... contamination of the aspirates with normal cells was determined by differential counts. The ratio of the peak channel numbers for the G1 phase of the tumor cells to that of the diploid standard (DNA index) was calculated and used for ploidy identification. Twenty-nine patients were evaluable with respect to DNA...

    Full Text Available Background. Whether or not the familial form of papillary thyroid carcinoma is more aggressive than the sporadic form of the disease remains controversial. Methods. To explore this question and whether or not increased aggressiveness is more apparent in families with multiple affected members, we performed a chi square by trend analysis on our patients clinical and pathologic data comparing: first degree families with three or more affected members versus first degree families with two affected members versus sporadic cases of papillary thyroid carcinoma. Results. No statistically significant trends were seen for any presenting surgical pathology parameter, age at presentation, length of follow-up or gender distribution. The familial groups exhibited significant trends for higher rates of reoperation (P=0.05 and/or requiring additional radioactive iodine therapy (P=0.03, distant metastases (P=0.003 and deaths (P=0.01. These aggressive features were most apparent in certain families with three or more affected members. Conclusions. Using the chi square by trend analysis, a significant trend was seen for the familial form of papillary thyroid cancer to possess more aggressive features than the sporadic disease. Prompt recognition of the familial nature of the disease may provide earlier diagnosis and treatment in similarly affected family members.

    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.

    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.

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

  16. Thyroid carcinoma. A descriptive retrospective study

    International Nuclear Information System (INIS)

    The thyroid carcinoma (TC) is not very frequent among all cancer. Its course is slow and is high potentially curable. Our aim was to analyse the characteristics in patients with TC. A retrospective analysis on 171 patients, with an average age of 41.1. (± 14.6), who asked for TC to our service between the years 2000-2004, was performed. From case histories it was evaluated: anamnesis, diagnostic image, histopathology and evolution. Tumours were grouped for size and TNM (tumor-nodule-metastasis) in stage (S). A simulated serum thyroglobulin level >2 ng/ml and positive image with 131I or another nuclear marker were considered as positive for residual TC. In the totality of the analyzed patients 88% were female, 62% below 45 years old, and in 77% the thyroid function was normal. The fine needle aspiration (FNA) was diagnostic in 78%. Papillary thyroid carcinoma (PTC) in 96%. The 63% was SI; 14% SII; 19% SIII and 4% SIV. During follow-up, we observed that 90% of patients with Tg between 2 and 10 had evidence of residual TC, and 100% with Tg > 10 ng/ml, whereas 18% of those whose simulated Tg < 2 presented positive image. There was not found significant correlation with pathologic antecedents or relevant image signs. In conclusion: TCP was the most frequent carcinoma in women, in patients younger than 45 years and in those who have euthyroid function. A simulated serum thyroglobulin level was a good indicator for residual TC, but bailed to select those patients who were disease free. (author)

    Objective: To evaluate the frequency and types of thyroid carcinoma with respect to age and sex groups. Methods: This was a retrospective study conducted at the Department of Pathology, Basic Medical Sciences Institute, Jinnah postgraduate medical centre Karachi. A total of 998 thyroid lesions over a period of 05 years, from July 2000 to June 2005 were reviewed. H and E slides were studied to determine the types and frequencies of malignant lesions of thyroid. Special stains were performed whenever required. Results: A total of 998 thyroid lesions were reviewed, of which 153 were found to be malignant. Papillary carcinoma was the commonest malignant lesion with a frequency of 90.2% followed by 4.5% medullary carcinoma, 2% follicular carcinoma, 2% undifferentiated carcinoma and 0.7% each of mixed medullary and papillary carcinoma and poorly differentiated carcinoma. Females were predominant 82.4% as compared to males 17.6% with female to male ratio 4.7:1. Maximum number of the patients were seen in fourth decade of life followed by third and second decades. Conclusion: The commonest malignant thyroid lesion was papillary carcinoma. Thyroid cancer was more common in females. Patients of papillary, medullary and follicular carcinomas were found in third and fourth decades of life while poorly and undifferentiated carcinomas were diagnosed from fifth to seventh decades of life.

    Medullary thyroid carcinoma (MTC) metastasizes to the regional lymph nodes and to the lungs, liver and bones. Only one case of recurrence of MTC involving the upper gastrointestinal tract has been reported so far. We describe the case of a 38-year-old woman with MTC, who developed an upper esophageal submucosal recurrence after two previous local recurrences treated surgically and one ethanol injection. After resection of the right lateral esophageal wall, calcitonin dropped by 60% and showed a doubling time >1 year. We cannot rule out the role of deep ethanol injection in the involvement of the cervical esophagus wall. PMID:26645011

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

    The authors report a very unusual occurrence of a metastatic squamous carcinoma to thyroid gland from a treated squamous cell carcinoma cervix 12 years before with no recurrence at the primary site. The case also has an additional complexity of rapid progression of the metastatic thyroid carcinoma to wide spread dissemination to lungs and bones while on concurrent chemo radio therapy confirming the aggressiveness of the entity

  1. Thyroid carcinoma: The experience at the Oncology Centre in Nicosia, Cyprus

    International Nuclear Information System (INIS)

    Full text: Carcinoma of the thyroid is usually of follicular cell origin. Four distinct histologic types of follicular cell-derived cancers (FCDC) are recognized. The majority of cases are papillary, with its major sub-type being the follicular variant (FVPTC). The other histological types are follicular, oxyphilic or Hurthle cell, and anaplastic. Each tumour type differs substantially in its initial mode of spread and subsequent pattern of recurrence and metastatic involvement. Although thyroid nodules are extremely common but clinically recognized thyroid carcinomas constitute less than 1% of all human malignant tumours. The annual incidence of thyroid cancer varies worldwide from 0.5 to 10 per 100000 population. In Cyprus, in the year 2000, there were 41 registered cases of newly diagnosed thyroid carcinoma (medullary excluded) in the Cancer Archive. This is an incidence of 5.6 per 100000. A Bank of Cyprus Oncology Center (BOCOC) was established in 1998 and very soon became the referral hospital for oncological patients in Cyprus. The thyroid clinic of the center was also established in that year which in collaboration with the NM department of the Nicosia General Hospital provided follow-up services to thyroid cancer patients. The Nuclear Medicine Department of the BOCOC was established on 1 July 2001 and since then the radioiodine therapy and follow-up thyroid carcinoma patients is done in this center. The patients are referred to the clinic after surgery and confirmed diagnosis of Thyroid Cancer. A total of 34 patients (5 males 29 females, age range 20-79 years) of thyroid carcinoma (medullary excluded) visited the clinic between July 2001 and July 2003. The histopathological form was 32 papillary and 2 follicular thyroid carcinoma. Of the 32 papillary 2 were metastatic, 4 papillary with follicular elements, 1 with papillary at the isthmus and follicular in right lobe and 1 papillary in the thyroglossal cyst. Preoperative diagnosis in most of the patients was

    Full text of the publication follows: Thyroid cancer is one of the malignancies most strongly associated with ionizing radiation in humans. Epidemiology studies of atomic bomb (A-bomb) survivors have indicated that excess relative risk of papillary thyroid cancer per Gy was remarkably high in the survivors. We therefore aim to clarify mechanisms linking A-bomb radiation exposure and development of papillary thyroid cancer. Toward this end, we intend to clarify characteristics of gene alterations occurring in radiation-associated adult-onset papillary thyroid cancer from the Life Span Study cohort of A-bomb survivors. We have thus far found that with increased radiation dose, papillary thyroid cancer cases with chromosomal rearrangements (mainly RET/PTC rearrangements) significantly increased and papillary thyroid cancer cases with point mutations (mainly BRAF-V600E) significantly decreased. Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

    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.

    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...

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

    Oncogenesis of anaplastic carcinoma of the pancreas is a subject of controversy, because it shows sarcomatous nature with extremely poor prognosis. We herein report an unusual case of anaplastic carcinoma occurring with a recurrent mucinous cystic neoplasm in a 38-year-old female. A 10-cm retroperitoneal cystic mass was pointed out in the first pregnancy and a probable diagnosis of mucinous cystic neoplasm was made in October 2000. She refused surgery first and delivered her baby uneventfully. During her second pregnancy in 2002, however, she presented hematemesis and underwent urgent distal pancreatectomy, splenectomy and partial resection of the gastric wall where the tumor perforated. A diagnosis of borderline-type mucinous cystic neoplasm with ovarian-like stroma was made. Nine months later, CT visualized a recurrent cystic tumor near the pancreatic stump, which was subsequently resected. Pathology revealed that the tumor was composed of two different components of borderline-type mucinous cystic neoplasm and anaplastic carcinoma. The latter was intensely positive for vimentin, CD68, p53 and focally for cytokeratin, suggesting both sarcomatous and carcinomatous differentiation. She survived four years after the second surgery without tumor recurrence. Although the origin of anaplastic carcinoma has not been determined yet, it should be remembered that anaplastic carcinoma can occur in association with mucinous cystic neoplasm of more benign histology.

    2016-01-01

    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.

    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.

  14. Management of thyroid carcinoma with radioactive 131I

    International Nuclear Information System (INIS)

    Purpose: To evaluate the role of radioactive 131I in the management of patients with well differentiated carcinoma of the thyroid. Methods and Materials: Between 1965 and 1995, a total of 117 patients with well-differentiated carcinoma of the thyroid underwent either lobectomy or thyroidectomy followed by 100-150 mCi of 131I. Results: With a median follow-up of 8 years, only four patients (3%) developed a recurrence of their disease. The 5-year actuarial survival was 97% with a 10-year survival of 91%. There were no severe side effects noted after 131I therapy. Conclusions: Radioactive 131I is a safe and effective procedure for the majority of patients with well-differentiated thyroid carcinoma. We currently recommend that all patients undergo a subtotal or total thyroidectomy followed by 131I thyroid scanning approximately 4 weeks after surgery. If the thyroid scan shows no residual uptake and all disease is confined to the thyroid, we recommend following patients with annual thyroid scans and serum thyroglobulin levels. If there is any residual uptake detected in the neck or if the tumor extends beyond the thyroid, we recommend routine thyroid ablation of 100-150 mCi of radioactive 131I

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

    Full Text Available Radiofrequency ablation (RFA recently has been applied to benign thyroid nodules, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of well-differentiated thyroid cancer, in the high-risk reoperative condition or for the palliative purpose. 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.

  17. Required therapeutic dose of 131I for thyroid ablation after surgery for differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text of publication follows. After operation for carcinoma of the thyroid gland a lot of patients are treated with radioactive iodine for ablation of the residual thyroid parenchyma. Aim: to determine the appropriate dose of radioactive iodine for ablation of the residual thyroid parenchyma in patients operated for differentiated thyroid carcinoma. Materials and methods: the study includes 316 patients who underwent a whole-body scan (WBS) scintigraphy with 131I. From 2009 to 2012 year 632 images were taken. Patients range from 21 to 78 years old. The scan was performed on a dual-headed gamma camera Siemens after an oral reception of a diagnostic dose 131I (2 mCi). The remnants of thyroid parenchyma were registered in 67 of the patients. 39 patients with registered remnants of thyroid parenchyma and slightly elevated thyroglobulin (TG) values who took therapeutic dose 131I (80-100 mCi) underwent a WBS scintigraphy with 131I and did not display remnants of thyroid parenchyma or extra thyroid accumulation of the radio nucleotide. 23 patients with several remnants of thyroid parenchyma and elevated values of TG who underwent a WBS scintigraphy with 131I eight to ten months after reception of the first dose therapeutic iodine (80-100 mCi) displayed persisting remnants of thyroid parenchyma. They were treated with a second dose of 131I (50-100 mCi). In 5 patients with high values of TG besides the thyroid remnants 3 of the patients displayed an extra thyroid accumulation in the lungs and 2 of them displayed an extra-thyroid fixation in the thoracic vertebras in addition to the fixation in the lungs. These 5 patients were treated twice with 131I, but still displayed the remnants of thyroid parenchyma and extra thyroid fixation. That group was treated with a third dose of 131I (30-50 mCi) and no remnants of thyroid parenchyma and extra-thyroid fixation of the radio nucleotide were visualized on the control WBS scintigraphy. Conclusion: in the majority of the patients

  1. The etiology of thyroid tumours

    International Nuclear Information System (INIS)

    The etiology of thyroid tumors is a complex subject, complicated by the fact that these tumors are not one entity, but separate neoplasms with different histology, evolution and prognosis. The recognized etiological factors of thyroid cancer include the iodine content of the diet, the inheritance, racial predispositions, the presence of an autoimmune thyroiditis and mostly, the exposure of the thyroid gland to external radiation following radiotherapy. The role played by these factors varies from one type of tumor to another. Thyroid radiation probably represents the most important factor in the development of a papillary carcinoma, with other factors (iodine-rich diet, inheritance, racial predispositions) having a minor role. The follicular carcinoma is more common in regions with low-iodine diet, therefore suggesting that TSH stimulation could be an etiological factor of these tumors. Thyroid radiation may also be carcinogenic for follicular carcinoma although less than for papillary carcinoma. Anaplastic carcinoma appears to originate from a papillary carcinoma already in the thyroid gland. In medullary carcinoma, inheritance plays a major role (autosomal dominant) and lymphomas occur in thyroids already affected by autoimmune thyroiditis. Recent experimental studies have suggested other possible cellular factors as responsible for the development of thyroid tumors. They include an alteration of the responsivity of TSH cellular receptors and the monoclonal mutation of C-cells. These new factors could provide a new insight on the etiology of thyroid tumors

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

    Full Text Available Hashimoto’s thyroiditis, the most common autoimmune thyroid disease, is due to destruction of the thyroid gland by autoantibodies. Various types of thyroid malignancies may arise in Hashimoto’s thyroiditis. Follicular carcinomas, papillary carcinomas, lymphomas, medullary carcinomas and hurthle cell neoplasms may develop in Hashimoto’s thyroiditis. We present a rare case report of a 35-year-old female who presented with hypothyroidism of a two-year duration. A diagnosis of Hashimoto’s thyroiditis was made for which she was under treatment. Due to the recent increase in size of the thyroid, a fine needle aspiration cytology was done. A preoperative diagnosis of Hurthle cell neoplasm was made based on fine needle aspiration cytology findings. The total thyroidectomy specimen revealed Hashimoto’s thyroiditis with synchronous papillary carcinoma and Hurthle cell carcinoma, which is a very rare occurrence.

    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.

  10. Treatment of thyroid carcinoma as a problem of internal medicine

    International Nuclear Information System (INIS)

    The usefulness of gallium-67 as a radiopharmaceutical for the detection of carcinoma of the thyroid gland is investigated. Gallium-67 does not accumulate in a benign goitre. In combination with iodide and pertechnetate scintigraphy of the thyroid, the application of gallium-67 is important for the detection of malignancy in large goitres. To increase the efficiency of iodine-131 therapy, a low-iodine diet and intensive diuresis during four days preceding administration of radioactive iodide is recommended

  11. Computed tomography of thyroid carcinoma with intrathoracic extension

    International Nuclear Information System (INIS)

    Eight cases of the thyroid carcinoma with intrathoracic extension were evaluated by CT. They consisted of 4 primary, and 2 recurrent thyroid carcinoma after palliative operation and another 2 mediastinal lymph nodes metastases after total thyroidectomy. Invasion to the trachea was correctly diagnosed in 5 of 6 cases. There were one false positive and one false negative case. The false negative case showed smooth compression deformity of the trachea by solid recurrent tumor. And the false positive case was a metastatic mediastinal lymph nodes which contained large cystic change and showed marked compression of the trachea. Involvement of large vessels, including the common carotid artery, internal jugular vein and innominate vein, were correctly diagnosed in all 5 cases. One recurrent tumor had esophageal invasion by thyroid carcinoma which could not be diagnosed preoperatively. The air filled esophagus did not show any deformity. (author)

    International Nuclear Information System (INIS)

    The incidence of thyroid cancer is the top ranking among endocrine carcinoma worldwide. Many imaging modalities have been applied in diagnosing, characterization of the biological behaviors and predicting the outcomes of various thyroid carcinoma. Over the years, 18F-FDG PET/CT has been largely used to identify undifferentiated thyroid carcinoma cells in thyroid carcinoma patients with or without 131I avid lesion. The purpose of this mini-review was to update the clinical role and positive impact of 18F-FDG PET/CT in various thyroid carcinoma patients. (authors)

    2014-12-01

    Full Text Available Osseous metastasis in patients of thyroid carcinoma is not very common, and appendicular skeleton is very rare. Bone metastasis represents a complication, especially of follicular thyroid carcinoma and severely reduces the quality of life causing pain, and fractures. Diagnosis is typically done by correlating clinical suspicion with imaging. Occult clinical presentations usually delay the detection and management of patients with bone metastasis from thyroid carcinoma. There is limited information about the clinical presentations and prognosis of patients with follicular thyroid carcinoma with bone metastasis. We hereby present a case report of right arm swelling diagnosed as metastatic carcinoma having metastasis from thyroid primary.

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

    Morisod, Benoît; Monnier, Philippe; Simon, Christian; Sandu, Kishore

    2014-08-01

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

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

    2006-09-01

    Full Text Available Abstract Background Collision tumors of the thyroid gland are a rare entity. We present a case of a follicular variant of papillary carcinoma and squamous carcinoma in the thyroid. To the best of our knowledge, this is the first documentation of a collision tumor with a papillary carcinoma and a squamous carcinoma within the thyroid gland. The clinicopathological features and immunohistochemical profile are reported. The theories of origin, epidemiology and management are discussed with a literature review. Case presentation A 65 year old woman presented with a large thyroid swelling of 10 years duration and with swellings on the back and scalp which were diagnosed to be a follicular variant of papillary thyroid carcinoma with metastasis. Clinical examination, radiology and endoscopy ruled out any other abnormality of the upper aerodigestive tract. The patient was treated surgically with a total thyroidectomy with central compartment clearance and bilateral selective neck dissections. The histopathology revealed a collision tumor with components of both a follicular variant of papillary carcinoma and a squamous carcinoma. Immunohistochemical analysis confirmed the independent origin of these two primary tumors. Adjuvant radio iodine therapy directed toward the follicular derived component of the thyroid tumor and external beam radiotherapy for the squamous component was planned. Conclusion Collision tumors of the thyroid gland pose a diagnostic as well as therapeutic challenge. Metastasis from distant organs and contiguous primary tumors should be excluded. The origins of squamous cancer in the thyroid gland must be established to support the true evolution of a collision tumor and to plan treatment. Treatment for collision tumors depends upon the combination of primary tumors involved and each component of the combination should be treated like an independent primary. The reporting of similar cases with longer follow-up will help define the

    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.

    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.

  10. Expression Patterns of Glucose Transporter-1 Gene and Thyroid Specific Genes in Human Papillary Thyroid Carcinoma

    International Nuclear Information System (INIS)

    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

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

    Full Text Available Thyroid cancer represents approximately 0.5–1% of all human malignancy1. In the UK the incidence of thyroid cancer is 2-3 per 100,000 populations 2. In geographical areas of low iodine intake and in areas exposed to nuclear disasters the incidence of thyroid cancer is higher. Benign thyroid conditions are much more common. In the UK approximately 8 % of the population have nodular thyroid disease2. Nodular thyroid disease increases with age and is also more common in females and in geographical areas of low iodine intake. Primary thyroid malignancy can be broadly divided into 2 groups. The first group, which generally have much better prognosis, are the well-differentiated thyroid carcinoma, which includes papillary carcinoma, follicular carcinoma and Hürthle cell tumours. The second group includes the poorly differentiated thyroid carcinoma like medullary thyroid carcinoma and the anaplastic thyroid carcinoma. Other rare tumours such as sarcomas, lymphomas and the extremely rare primary squamous cell carcinoma of the thyroid should be included in the second group. Secondary or metastatic thyroid cancer can be from breast, lung, colon and kidney malignancies.

    Full Text Available Nutritional factors are known to be important in the development of different metabolic diseases. 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.

  17. Postirradiation carcinoma of the thyroid gland

    International Nuclear Information System (INIS)

    In the early 1920's many infants and children received x-ray therapy for such conditions as enlarged thymus, hypertrophy of the tonsils and adenoids, cervical adenitis, sinusitis, and so forth. Unfortunately, the thyroid gland frequently received direct or scattered irradiation during these treatments. As the irradiated population has grown older it has become apparent that these people have an increased incidence of thyroid cancer. Recent publicity on this problem in the newspaper, radio, and television has alarmed individuals or their parents who in turn have consulted their physicians for advice. All individuals with a history of head and neck irradiation should be considered as having an increased risk of developing thyroid cancer. These patients should be examined every two years indefinitely. Fortunately, only a small percentage of irradiated individuals develop thyroid tumors. Most of the tumors found have been benign. Those which are malignant have been well differentiated, papillary, or follicular neoplasms which grow slowly, metastasize relatively late, and are curable by surgical removal before metastasis has occurred. If on palpation of the thyroid gland one or more firm, discrete nodules are palpated, these should be removed regardless of other findings. A scan may be useful in assessing the functional status of the nodule and may give some indication as to whether the nodule is malignant or benign. If the scan shows a cold area which corresponds with a palpable mass, the patient should be considered for prompt surgical exploration. If the scan shows a hot nodule, it is usually not malignant, but should be closely observed for change

    Conclusion: According to difference between plasma levels of osteocalcin and retinol binding protein-4 in patients suffered of medullary thyroid carcinoma comparison with normal subjects, it can be said that, probably medullary thyroid carcinoma has effect on bone and adipose tissue metabolism, so osteocalcin and retinol binding protein-4 hormones have potential to be used for confirmation of diagnosis or following treatment of medullary thyroid carcinoma.

  19. Oral TRH stimulation of the thyroid in patients with thyroid carcinoma

    International Nuclear Information System (INIS)

    In patients with differentiated thyroid carcinoma high serum TSH-levels enhance 131J-uptake in thyroid remnant and/or metastases. An effective increase of TSH could be achieved by oral administration of thyrotropin releasing hormone (TRH) even after a short T4/T3-withdrawal period so that we recommend a TRH-stimulation in all patients before a diagnostic or therapeutic 131J-application. Adverse reactions to TRH are infrequent and usually shorttimed so that-in contrast to TSH-stimulation - TRH can be given to outpatients without any risk. (orig.)

  20. Practical management of well differentiated thyroid carcinoma in Korea

    International Nuclear Information System (INIS)

    The optimal extent of surgery and postoperative management of patients with well differentiated thyroid carcinoma (WDTC) vary among countries and institutions. We assessed the practical management of WDTC in Korea by questionnaire and compared these results with those obtained in similar surveys of members of the Japanese Society of Thyroid Surgery (JSTS) and the International Association of Endocrine Surgeons (IAES). Questionnaires were sent by mail or e-mail to 266 members of the Korean Association of Endocrine Surgeons (KAES). Ninety members (33.8%) completed the questionnaire; their responses were compared with those of the JSTS and IAES surveys. Total thyroidectomy was more prevalent in the KAES and IAES than in the JSTS, irrespective of tumor size in the low-risk group. Patients with papillary microcarcinoma were more likely to undergo aggressive central compartment node dissection in the KAES than in the IAES or JSTS. Thyroid stimulating hormone suppression therapy was administered to a higher proportion of patients and for longer times in the KAES and IAES than in the JSTS. Postoperative radioactive iodine treatment was more prevalent in the KAES than in the JSTS. There were no differences between the KAES and the JSTS in the treatment of patients with locally advanced thyroid carcinoma. External irradiation and radioactive iodine treatment for recurrent papillary thyroid carcinoma were favored more by the KAES than the IAES and JSTS. The actual practices of members of the KAES were almost similar to those of the IAES, but differed from those in Japan in some aspects. In general, however, members of the KAES favored more aggressive treatment of WDTC than did physicians in other countries. (author)

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

    Full Text Available Abstract Background The occurrence of skin metastases are rare events in the course of a follicular thyroid carcinoma (FTC and usually indicate advanced tumor stages. The scalp is the most affected area of these metastases. Case presentation We present a case of a 76 year old Woman with multiple giant scalp metastases of a follicular carcinoma. These metastases had been resected and wounds had been closed with mesh graft. The 14-months follow up is presented. Conclusion We demonstrate another case with multicentric form. Because of its location and size a primary wound closure was not possible. A healing could be reached using vacuum therapy and mesh graft transplantation.

  5. Protocol for thyroid remnant ablation after recombinant TSH in thyroid carcinoma

    International Nuclear Information System (INIS)

    In some countries, in order to perform rhTSH-aided thyroid remnant ablation (TRA) after surgery, it is generally necessary to confirm that thyroidectomy has been almost complete. Otherwise, the nuclear medicine specialist will not administer a high radioiodine dose because it might be hazardous due to the possibility of thyroid remnant actinic thyroiditis. Considering this, it would be necessary to use two rhTSH kits (one for diagnostic purposes and the other one to administer the 131I dose). In this study, we used an alternative protocol for TRA with the use of one kit of rhTSH in twenty patients diagnosed with low risk papillary thyroid carcinoma. All patients had negative titers of anti-thyroglobulin antibodies. Successful thyroid remnant ablation was confirmed with an undetectable rhTSH stimulated thyroglobulin level (< 1 ng/ml) in all 20 patients between 8 to 12 months after radioiodine administration. The use of this protocol combining scintigraphy with the subsequent administration of a therapeutic dose following the administration of one kit of rhTSH would avoid the need of using 2 kits to perform the ablation and would decrease the costs associated with its use while significantly enhancing the quality of life of patients with thyroid cancer.

  10. The molecular biological characteristics of childhood thyroid carcinoma

    International Nuclear Information System (INIS)

    We have used molecular biology to study mutation and expression of key oncogenes in childhood thyroid carcinomas from Belarus and Ukraine. All cases were histologically verified by two or more pathologists including at least one from the CIS and one from the EU. We chose to study six genes which have been shown to be involved in thyroid carcinogenesis in adults: ret. Ha, Ki and N ras genes, p53 and the TSH receptor. Expression of the ret oncogene, which has been shown to be activated by translocation in a proportion of papillary carcinomas has been studied by two independent methods. The first, used by the Cambridge group uses RT-PCR to identify the expression of the tyrosine kinase domain of the gene; as the gene is normally silent in follicular cells, this approach allows demonstration of activation of ret, but does not identify the particular translocation involved. The second approach, used by the Naples group, also uses RT-PCR, but amplifies across the breakpoint of each of the three translocations already identified to provide information on the proportion of tumors which express the individual translocations of this gene. Mutations in the TSH receptor, a key modulator of thyroid follicular growth have been sought by the Brussels group using SSCP and direct sequencing. The Munich group have analyzed the samples for presence of mutation in p53, which is believed to play a role in genetic instability which is a features of carcinomas derived from may different tissues. Mutations in the common sites of the ras oncogenes have been studied by the Cambridge group. Analysis of 26 papillary carcinomas so far studied has shown that mutations in the TSH receptor and in p53 do not play a significant role in the genesis of the tumours studied. The proportion of tumours showing ret expression does not differ significantly from that found in a control non exposed population from the UK. However, the pathological study shows that nearly all the increased number of thyroid

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

    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.

  13. Somatostatin receptors and somatostatin content in medullary thyroid carcinomas

    International Nuclear Information System (INIS)

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

  14. Clinicopathological and Molecular Histochemical Review of Skull Base Metastasis from Differentiated Thyroid Carcinoma

    International Nuclear Information System (INIS)

    Skull base metastasis from differentiated thyroid carcinoma including follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) is a rare clinical entity. Eighteen FTC cases and 10 PTC cases showing skull base metastasis have been reported. The most common symptom of skull base metastasis from FTC and PTC is cranial nerve dysfunction. Bone destruction and local invasion to the surrounding soft tissues are common on radiological imaging. Skull base metastases can be the initial clinical presentation of FTC and PTC in the presence of silent primary sites. The possibility of skull base metastasis from FTC and PTC should be considered in patients with the clinical symptoms of cranial nerve dysfunction and radiological findings of bone destruction. A variety of genetic alterations in thyroid tumors have been identified to have a fundamental role in their tumorigenesis. Molecular histochemical studies are useful for elucidating the histopathological features of thyroid carcinoma. Recent molecular findings may provide novel molecular-based treatment strategies for thyroid carcinoma

    Full Text Available Malignant lesion of a thyroglossal duct cyst (TGDC is an extremely rare entity. Papillary carcinoma is the most common malignancy of the endocrine system. Diagnosis is commonly made after pathological examination of the surgical specimen. A 41-year-old male patient with a midline neck mass was initially diagnosed with a thyroglossal duct cyst and underwent a Sistrunks procedure. Histopathologic examination revealed a papillary thyroid car¬cinoma within the thyroglossal duct cyst. Ultrasound elastography of the thyroid gland was performed. We have detected a hypoechoic hypervascular thyroid nodule measuring 3 mm in diameter that appeared completely blue in B-mode ultrasonography, and hard tissue was visualized by elastosonography (ES. The patient then underwent total thyroidectomy and bilateral neck dissection. The final pathological finding showed papillary microcarcinoma of the thyroid gland without cervical lymph node metastasis. When a thyroglossal duct cyst is excised using Sistrunk’s procedure and when the definitive hystological analysis depicts malignancy, the thyroid gland must be studied carefully with radiological examinations.

  17. Prognostic variables of papillary thyroid carcinomas with local invasion

    International Nuclear Information System (INIS)

    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 (131I) therapy while 22 patients received external radiotherapy in the neck and upper mediastinum area post-operatively. In the study, age, gender, 131I 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 Syndrome of inappropriate antidiuretic hormone secretion (SIADH is one of the most common causes of hyponatremia. The usual causes are malignancies, central nervous system, pulmonary disorders, and drugs. Amiodarone is a broad spectrum antiarrhythmic agent widely used in the management of arrhythmias. The different side effects include thyroid dysfunction, visual disturbances, pulmonary infiltrates, ataxia, cardiac conduction abnormalities, drug interactions, corneal microdeposits, skin rashes, and gastrointestinal disturbances. SIADH is a rare but lethal side effect of amiodarone. We describe a 62-year-old male who was suffering from advanced prostatic malignancy, taking amiodarone for underlying heart disease. He developed SIADH which was initially thought to be paraneoplastic in etiology, but later histopathology refuted that. This case emphasizes the importance of detailed drug history and the role of immunohistochemistry in establishing the diagnosis and management of hyponatremia due to SIADH.

    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.

    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.

  2. Cardiac, choroidal and subcutaneous metastases of a follicular thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text of publication follows. Aim: to describe an unusual case of follicular carcinoma of the thyroid with uncommon metastases at the left atrium, the pulmonary vessels, the right eye and a subcutaneous mass. Materials and methods: the patient record was reviewed retrospectively. We analysed clinical outcomes and thyroglobulin rate as well as imaging findings after radio-iodine therapy. Results: we report the case of 43-year-old woman operated in 1995 for multi-nodular goitre by total thyroidectomy. Histopathologic findings were typical of follicular thyroid carcinoma with vascular invasion. The patient was then lost of sight and consulted in 2000 for a neck swelling. She was operated again for lymphadenectomy with resection of two peri-jugular tumoral masses that deviate vascular axes. Histopathologic findings concluded for residual follicular thyroid carcinoma with insular component without lymph node metastasis. The initial chest CT revealed a macro-nodular lung miliairy and the whole body scan post 100 mCi Iodine-131 showed intense cervical uptake and multiple bilateral thoracic fixations. The evolution after 10 cures of Iodine-131 has been marked by a persistently high thyroglobulin levels superior to 800 ng/ml with disappearance of cervical uptake and the persistence of pulmonary fixations. Bone scintigraphy scan was negative. Later, the patient complained of a decreased visual acuity. The last whole body SPECT/CT scan revealed multiple fixations of I-131 located at the right eyeball, lungs, left atrium, liver, sacrum as well as an abdominal subcutaneous solid mass. MRI confirmed a right choroid metastasis. Conclusion: follicular thyroid carcinoma comprises 15% of all thyroid cancers and usually metastases to the lymph nodes, lungs and bone. Other rare sites of metastases are the brain, pituitary, maxilla, larynx, and thymus. Distant metastases of these sites, particularly choroidal are exceptional. Metastatic cardiac involvement occurs most often during

    2016-01-01

    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.

  4. The application of molecular nuclear medicine in imaging diagnosis and targeted treatment of thyroid carcinoma

    International Nuclear Information System (INIS)

    Thyroid carcinoma is the most common malignancy of endocrine system. Different pathological classifications of thyroid carcinoma differ greatly in biological behavior and prognosis. As a newly-emerging subject, molecular nuclear medicine has made rapid advances in both diagnosis and treatment of thyroid carcinoma. With the application of new imaging agents and devices such as SPECT/CT and PET/CT, molecular nuclear imaging can demonstrate, both qualitatively and quantitatively, the alterations in specific molecules of thyroid cancer on cellular and molecular level. Meanwhile, it is capable of utilizing radiopharmaceuticals to target specifically to these molecules. Here we present a review on the latest progresses in this field. (authors)

    International Nuclear Information System (INIS)

    It has been reported that 67Ga uptake by malignant tumors differs somewhat according to the histologic type. Previously, we reported that uptake of 67Ga is predictably low in well-differentiated adenocarcinoma of the thyroid gland but high in anaplastic carcinoma and malignant lymphoma. We studied the relationship between 67Ga uptake and nuclear DNA content in four papillary adenocarcinomas, three follicular adenocarcinomas, three anaplastic carcinomas, and five malignant lymphomas of the thyroid gland. In anaplastic carcinoma and malignant lymphoma, the nuclear DNA content and proliferative index were significantly higher than in well-differentiated adenocarcinoma. These results suggest that there is close correlation between 67Ga uptake and degree of malignancy of thyroid tumor cells

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

    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.

    Full Text Available Thyroid angiosarcomas are typically infiltrative and large tumors with very similar clinical findings of anaplastic carcinoma of thyroid. Early hematogenous metastasis is very frequent, but regional lymph node metastasis is quite rare. We present a case of angiosarcoma of the thyroid gland in a 68 years old man with regional lymph node metastasis. Total thyroidectomy with right modified radical neck dissection was applied. Four out of 19 lymph nodes dissected were seen to contain metastasis. Metastatic tumor was composed of sarcomatous areas containing large numbers of blood filled clefts. There after the surgery PET-CT was performed and multiple metastatic involvements were reported. Thyroid angiosarcomas are completely different tumors from angiomatoid anaplastic carcinomas. Longer survival with these tumors is only possible with agressive surgery and in case of regional LN metastasis, neck dissection should be done.

  13. Handling of ganglion in papillar carcinoma of thyroid

    International Nuclear Information System (INIS)

    The reports in the literature present different concepts regarding the handling of the ganglion for the well-differentiated carcinoma of the thyroid. From the tumor diagnosis, until the aspects presage of the same one, important controversies exist regarding the tumoral biology. The statistical analyses offer diverse conclusions that can support some or other postures. In the United States they are diagnosed 17.200 new cases of thyroid cancer annually, with an annual mortality of 1200 people. The varied behavior of this illness, makes that the points of view are multiple and it becomes necessary to have an own statistic at least as comparison point to suggest the handlings but chords to the population in study, because it is debated largely if the presence or not of the adenopatie they influence in the relapse and in the survival of these patients

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

  15. Quantitative evaluation of radiodine ablation of the thyroid in patients with differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: We have developed a novel method of quantitative analysis of post radioiodine ablation scans for differentiated carcinoma of the thyroid to enable an objective comparison of patients receiving recombinant TSH with those who have had withdrawal of thyroid hormone supplements. Reliance on visual estimation of the completeness of thyroid ablation can have errors related to observer variation and variation in the settings of the display. Traditionally a neck uptake of 2 (chi squared). Low values of minimum X2 correlate well with an absence of uptake in residual thyroid tissue. In areas with increased activity, comparison with the fitted curve is used to give a value in units of statistical error or standard deviation (S.D.). The method has been tested in a series of 36 consecutive patients following radioiodine ablation. The patients were divided visually into three groups: complete ablation (17), normal excretion into the oesophagus (7) and focal residual uptake in tumor or normal thyroid (12). In the complete ablation group the maximum variation from the fitted curve ranged from 2.0 to 4.1 S.Ds. (with a mean of 2.7 f 0.14 S.E.). In patients with a visible linear uptake in the oesophageal region the variation ranged from 3.0 - 4.5 S.Ds.. In those patients with focal uptake the variation ranged from 4.8 S.Ds. to 83 S.Ds.. This technique has proved to be a valuable method of quantitative thyroid ablation especially when there are equivocal areas of low focal uptake. The technique can be applied to equally to any situation where it is necessary to confirm that variation in uptake is within normal limits where the background activity changes, e.g. with the changing shape of an organ, or where it is difficult to define a 'normal' symmetrical region of interest.

    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.

    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.)

  18. The pathology of childhood thyroid carcinoma in Belarus

    International Nuclear Information System (INIS)

    We have studied data on the sex and age distribution of 293 cases of thyroid carcinoma in children operated in Belarus between January 1990 and December 1994. We have also reviewed the histology of 134 cases and performed immunocytochemistry for calcitonin, thyroglobulin, ret, met and p53 and in situ hybridisation for thyroglobulin and calcitonin on a sample of these cases. We have compared the data derived from this series with those obtained from a similar series of 122 cases operated in Kiev, Ukraine over the same time period and those from 154 cases operated in England and Wales over a 30 year period. There was agreement on the diagnosis of malignancy in 132 of the 134 Belarussian cases (98%). In 2 of the cases there was no evidence of malignancy in the material seen in Cambridge, but not all the original pathological material was available for review. In 7 cases there was evidence of malignancy, but inadequate material to determine the subtype of malignancy. The papillary carcinomas were classified as of the classic type when they showed a papillary architecture and the nuclear features typical of adult papillary carcinoma, or of the solid follicular type as described in the series studied in England and Wales (1). Four were papillary micro carcinomas. The age and sex distribution of all cases from Belarus showed a markedly different pattern from that observed in England and Wales. In Belarus the peak was at age 9, while the England and Wales series showed a smooth rise in incidence with increasing age. Virtually all the cases from Belarus were papillary carcinoma (99%) compared with only 68% in England and Wales. In addition, there was a higher proportion of papillary carcinomas of the solid/follicular type (72% in Belarus, 35% in England and Wales). The frequency of this subtype did not change significantly with age in Belarus, whereas there was a relative decrease from 62% in the 0-9 year age group to 23% in the 10-14 year age group in England and Wales

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

    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.

  1. HABP2 G534E Variant in Papillary Thyroid Carcinoma.

    Directory of Open Access Journals (Sweden)

    Jerneja Tomsic

    Full Text Available 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.

  2. Carcinoma of the Thyroid. Preoperative diagnostic and prognostic factors

    International Nuclear Information System (INIS)

    By improving preoperative diagnosis and identification of important prognostic factors of thyroid carcinoma (TC) it might be possible to decrease the number of diagnostic surgical intervantions and to give patients with a confirmed TC a more adequate treatment. Preoperative diagnosis: consecutive series of 83 patients with scintigrams and of 203 patients with fine-needle aspiration (AC) with subsequently histologically confirmed TC were evaluated as well as 217 patients with confirmed benign thyroid disorders. The most common scintigraphic appearance was a solitary reduced uptake (70%). The sensitivity of AC for medullary and undifferentiated TC was 0.82-0.84, but it was for papillary (occult TC excluded) 0.58 and for follicular TC 0.42. A 'cold' nodule with also a decreased thallium-uptake is mostly a benign disorder, but with an increased uptake it might be a well-differentiated TC or a follicular adenoma. These could, however, be significantly separated by the thallium-elimination rate (p=0.0001). Prognostic factors: During 1955-1972, 262 patients with histologically verified TC were referred to the Department and 226 of these (86%) with a median follow-up of 11 years form the basis for prognostic multivariate analyses. According to these analyses, and when deaths in intercurrent disease were estimated, neither age at diagnosis nor sex were found to be important predictors of survival of TC. The following predictors were identified: for papillary TC: tumour extension beyond the thyroid capsule and marked cellular atypia; for follicular TC: tumour extension beyond the thyroid capsule, marked cellular atypia and distant metastases; for medullary TC: tumour extension beyond the thyroid capsule.

  3. Inhibition of carcinoma formation and of vascular invasion in grafts of radiation-initiated thyroid clonogens by unirradiated thyroid cells

    International Nuclear Information System (INIS)

    Quantitative transplantation techniques have been employed to study radiogenic cancer initiation frequency and cell interactions during promotion/progression in grafted clonogenic rat thyroid epithelial cells. The graft recipients were surgically thyroidectomized. Radiogenic initiation is a common cellular event; one of ∼ 32 surviving 5-Gy-irradiated thyroid clonogens gave rise to cancer in grafts initially containing ∼ 11 clonogens per transplantation site. The efficiency of promotion/progression is inversely related to grafted irradiated cell number. As the number of transplanted surviving irradiated clonogens was increased progressively from ∼ 11 to ∼ 720 clonogens per graft site, the carcinoma frequency per grafted clonogen progressively decreased to one per ∼ 920. Addition of unirradiated thyroid cells to the transplant inocula further suppressed promotion/progression of radiation-initiated thyroid clonogens. Furthermore, the probability of vascular invasion, a reflection of metastatic potential in carcinomas which arose from irradiated grafted thyroid clonogens, was reduced by addition of unirradiated thyroid cells to the transplant inocula. Assays of thyroid stimulating hormone (TSH) titers in the sera of thyroidectomized rats 44 weeks after transplantation of clonogenic thyroid cells indicate that the suppression of neoplastic promotion/progression observed with increased numbers of cells per graft site is due at least in part to feed-back inhibition of TSH production by thyroid hormone of graft origin.

    Full Text Available Abstract Background Cell lines are often poorly characterized from a genetic point of view, reducing their usefulness as tumor models. Our purpose was to assess the genetic background of eight commonly used human thyroid carcinoma models and to compare the findings with those reported for primary tumors of the gland. Methods We used chromosome banding analysis and comparative genomic hybridization to profile eight non-medullary thyroid carcinoma cell lines of papillary (TPC-1, FB2, K1 and B-CPAP, follicular (XTC-1 or anaplastic origin (8505C, C643 and HTH74. To assess the representativeness of the findings, we additionally performed a thorough review of cytogenetic (n = 125 and DNA copy number information (n = 270 available in the literature on clinical samples of thyroid carcinoma. Results The detailed characterization of chromosomal markers specific for each cell line revealed two cases of mistaken identities: FB2 was shown to derive from TPC-1 cells, whereas K1 cells have their origin in cell line GLAG-66. All cellular models displayed genomic aberrations of varying complexity, and recurrent gains at 5p, 5q, 8q, and 20q (6/7 cell lines and losses at 8p, 13q, 18q, and Xp (4/7 cell lines were seen. Importantly, the genomic profiles were compatible with those of the respective primary tumors, as seen in the meta-analysis of the existing literature data. Conclusion We provide the genomic background of seven independent thyroid carcinoma models representative of the clinical tumors of the corresponding histotypes, and highlight regions of recurrent aberrations that may guide future studies aimed at identifying target genes. Our findings further support the importance of routinely performing cytogenetic studies on cell lines, to detect cross-contamination mishaps such as those identified here.

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

    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.

  10. Thin needle aspiration biopsy in diagnosis of thyroid gland carcinoma

    The increase of thyroid gland cancer in people of Belarus is one of the most actual medical problems appeared after the Chernobyl disaster. During the period 1986 -1999 in Belarus were revealed 6901 cases of cancer in the adults and 673 -in the children. Compared with the pre-disaster period the increase of the pathology has made 4.7 and 84 times correspondingly. In Magilew region during post-disaster years were revealed 899 cases of thyroid gland cancer in the adults and 34 -in the children. From the year 1998 perceptible rise of disease appeared in people over 19 years old. According to the prognosis of specialists the problem of high thyroid gland carcinoma rate will be actual for years, gradually decreasing in the children and increasing in the adults. Thyroid gland cancer promoted by radiation has very aggressive nature. According to the data of Republican science-practical thyroid gland tumors center even small carcinomas (3-9 mm) can give numerous metastasis to lymph nodes and lungs. The possibility of tumor growth to the nearest tissues is very high. That's why the early diagnostic of the pathology is important. Medical help to the patients with thyroid gland cancer and other node formations consist in the complex problem solution: early node formation revealing by ultrasonic method, early diagnosis verification with the help of cytological bio-assays examination, received by the way of the thin needle aspiration biopsy (TNAB) under ultrasonic control, surgical treatment, radio iodine therapy, rehabilitation and prophylactic medical examination. Under the problem of early thyroid carcinoma revealing they understand exact diagnostic and surgical treatment in the stages pT1, pT1a and pT1b, N0, M0. In 1993 -1999 in the diagnostic center 139,2 thousand patients were surveyed. In the pointed cases 10739 thin needle aspiration biopsies under ultrasonic control were made and the bioassays received were studied cytologically. Ultrasonic examinations and TNAB were

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

    Background The prevalence and pathology pattern of iodine deficiency (ID) related disorders are influenced by the dietary iodine intake: low iodine leads to thyroid nodular enlargement, to an increase in the incidence of thyroid cancer, an increase in anaplastic carcinomas and to an alteration in the papillary to follicular neoplasia ratio. This study aims at highlighting the effects of ID by comparatively evaluating the pattern of thyroid nodular pathology in different populations that, alth...

  13. The indication for 131I-therapy in occult thyroid carcinoma

    International Nuclear Information System (INIS)

    The prevalence of occult papillary thyroid carcinoma in the normal population is several orders of magnitude higher than the incidence of clinically apparent thyroid cancer, and the recurrence rate or mortality is very low, even after conservative therapy. Therefore, occult papillary thyroid carcinoma has to be considered as distinct biologic entity. Therefore, we recommend no further surgery or ablation of the thyroid remnant with 131I for patients less than 40 years old with occult papillary carcinoma without metastases. In case of metastases, however, 131I-therapy should be performed after total thyroidectomy. All follicular thyroid carcinomas, regardless of their size, are to be treated by total thyroidectomy and 131I-therapy. All patients receive TSH-suppressive levothyroxine therapy and undergo regular follow-up. (orig.)

    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.

    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.)

    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

  17. Bone marrow changes in patients with thyroid carcinoma

    International Nuclear Information System (INIS)

    In 62 patients with thyroid carcinoma 79 MRI bone marrow examinations and 48 bone marrow scintigraphies were recorded before or following radioiodine therapy, to study the extent of bone marrow expansion. The results of both methods were the same. In 34/79 investigations normal findings were seen, in 18 the bone marrow expanded to the middle third and in 26 to the distal third of the femur. One patient showed bone marrow expansion to the tibia. These results were compared with the following data: Histology of tumor, TNM-staging, time passed since thyroidectomy, accumulated doses of radioiodine therapy, results of 131I scintigraphy, hematological changes, thyroglobulin level, age and sex. No significant correlations were found between these and the bone marrow imaging results. Bone marrow changes in patients before radioiodine therapy were similar to those in patients treated with up to 48 GBq 131I. Blind biopsy of the posterior iliac crest in five patients showed slightly pathological reactive changes. In only 2/17 follow-up studies an increase of bone marrow expansion was seen. In 8 patients localized findings indicating malignant infiltration were observed. In 4/8 patients metastases of thyroid carcinoma were known or confirmed by pathological radioiodine uptake and in 2/8 metastatic involvement was assumed because of an increased thyroglobulin level.

  19. Diffuse Sclerosing Variant of Papillary Thyroid Carcinoma: a Histological Type With Difficult Diagnosis

    International Nuclear Information System (INIS)

    The papillary thyroid carcinoma is the most frequent thyroid neoplasm and usually it is a non aggressive tumor; nevertheless, some histological variants such as the diffuse sclerosing variant are more aggressive producing locoregional invasion and distant metastasis. This specific variant challenges the pathological diagnosis since the architectural and cytological characteristics might be confusing, particularly regarding benign lesions such as the lymphocytic thyroiditis. We present a case report of a patient at the National Cancer Institute of Colombia with a lung metastasis from a diffuse sclerosing papillary thyroid carcinoma. The difficulties for diagnosis, for both clinical and pathology experts, are illustrated as well as their relevance for determining the biological course of the disease.

FDG uptake was detected in the uterus, where the primary cancer was located, and in the left lobe of the thyroid gland. The biopsy sample from the hypermetabolic nodular lesion in thyroid gland revealed intermediate cytology according to Bethesda Classification. The patient underwent hysterectomy and thyroidectomy. An endometrial carcinoma in the uterus and a multicentric thyroid papillary carcinoma in the thyroid gland were diagnosed.

  1. Natural history, treatment, and course of papillary thyroid carcinoma

    International Nuclear Information System (INIS)

    We have analyzed the course of papillary thyroid carcinoma in 269 patients managed at the University of Chicago, with an average follow-up period of 12 yr from the time of diagnosis. Patients were categorized by clinical class; I, with intrathyroidal disease; II, with cervical nodal metastases; III, with extrathyroidal invasion; and IV, with distant metastases. Half of the patients had a history of thyroid enlargement known, on the average, for over 3 yr. In 15% of patients given thyroid hormone, the mass decreased in size. The peak incidence of cancer was when subjects were between 20-40 yr of age. Tumors averaged 2.4 cm in size; 21.6% had tumor capsule invasion, and 46% of patients had multifocal tumors. Sixty-six percent of the patients had near-total or total thyroidectomy. The overall incidence of postoperative hypoparathyroidism was 8.4%, but the incidence was zero in 83 near-total or total thyroidectomies carried out by 1 surgeon. Twenty-five percent of the patients had continuing or recurrent disease, and 8.2% died from cancer. Deaths occurred largely in patients with class III or IV disease. Cervical lymph nodes were associated with increased recurrences, but not increased deaths. Extrathyroidal invasion carried an increased risk of 5.8-fold for death, and distant metastases increased this risk 47-fold. Age over 45 yr at diagnosis increased the risk of death 32-fold. Tumor size over 3 cm increased the risk of death 5.8-fold. Surgical treatment combining lobectomy plus at least contralateral subtotal thyroidectomy was associated, by Cox proportional hazard analysis, with decreased risk of death in patients with tumors larger than 1 cm and decreased risk of recurrence among all patients, including patients in classes I and II, compared to patients who underwent unilateral thyroid surgery or bilateral subtotal resections

    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.

    Adjuvant therapy with ablative radioiodine after surgical resection of apparently localized thyroid carcinoma remains controversial because of the favorable prognosis of thyroid carcinoma and the risk of leukemia from the radioiodine. No controlled trials have been performed to examine this issue. We constructed a decision analytic model to examine whether patients with apparently localized thyroid carcinoma should receive radioiodine. Our analysis suggests that radioiodine modestly improves life expectancy by 2 to 15 months, depending on the patient's age and sex. This model predicts that the benefit of a reduction in the likelihood of recurrence outweighs the risk of leukemia from radioiodine.

  4. Imaging of metastases from a thyroid carcinoma using 111In pentetreotide

    International Nuclear Information System (INIS)

    There is little experience with imaging of thyroid carcinoma tissue by somatostatin receptor scintigraphy. Our case report describes an acromegalic patient, in whom 111In pentetreotide scintigraphy did not only demonstrate a receptor-positive pituitary tumor but also visualized metastases from a papillary thyroid carcinoma which had no correlate in radioiodine scintigraphy carried out under hypothyroid conditions. The possible role of this radiopharmaceutical in dedifferentiating thyroid carcinoma is discussed for its usefulness in tumor localisation and its predictive value for the outcome of an octreotide therapy.

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

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

    The aim of this study was to evaluate the oncologic safety of robot thyroid surgery compared to open thyroid surgery for papillary thyroid carcinoma (PTC). We enrolled 722 patients with PTC who underwent a total thyroidectomy with central compartment node dissection (CCND) from January 2009 to December 2010. These patients were classified into open thyroid surgery (n = 610) or robot thyroid surgery (n = 112) groups. We verified the impact of robot thyroid surgery on clinical recurrence and ablation/control-stimulated thyroglobulin (sTg) levels predictive of non-recurrence using weighted logistic regression models with inverse probability of treatment weighting (IPTW). Age, sex, thyroid weight, extent of CCND, and TNM were significantly different between the two groups (p robot groups (1.5% vs. 2.7%; p = 0.608). The proportion of patients with ablation sTg 0.05). Logistic regression with IPTW using the propensity scores estimated by adjusting all of the parameters demonstrated that robot thyroid surgery did not influence the clinical recurrence (OR; 0.784, 95% CI; 0.150–3.403, p = 0.750), ablation sTg (OR; 0.950, 95% CI; 0.361–2.399, p = 0.914), and control sTg levels (OR; 0.498, 95% CI; 0.190–1.189, p = 0.130). Robot thyroid surgery is comparable to open thyroid surgery with regard to oncologic safety in PTC patients. PMID:27285846

    Full Text Available Abstract Background Peptidyl-prolyl cis/trans isomerase (Pin1, encoded by PIN1 gene with locus in chromosome 19p13, is an enzyme that catalytically induces conformational changes in proteins after phosphorylation on serine or threonine residues preceding proline (pSer/Thr-Pro motifs; in this way, it has an influence on protein interactions and intracellular localizations of proteins. The aim of the study were: 1 an assessment of PIN1 gene expression level in benign and malignant thyroid lesions; 2 the evaluation of possible correlations between gene expression and histopathological variants of papillary thyroid carcinoma (PTC or tumour size, classified according to TNM classification of primary tumours (in case of PTC only; 3 the estimation of possible relationships between expression of the gene in question and patients' sex or age. Methods Seventy (70 tissue samples were analyzed: 32 cases of PTC, 7 cases of medullary thyroid carcinoma (MTC, 7 cases of follicular adenoma (FA, and 24 cases of nodular goitre (NG. In real-time polymerase chain reaction (real-time PCR, two-step RT-PCR (reverse transcriptase-polymerase chain reaction in an ABI PRISM 7500 Sequence Detection System was employed. The PIN1 gene expression level was assessed, calculating the mean relative quantification rate (RQ rate increase for each sample. Results The level of PIN1 gene expression (compared to that in macroscopically unchanged thyroid tissue was higher in PTC group than those in FA, MTC and/or NG groups, but the statistical significance was noted for difference between PTC and NG groups only. On the other hand, the differences of RQ rate value between different PTC variants were statistically insignificant. No correlations were found between RQ values and tumour size, as well as between RQ values and patients' sex or age in PTC group. Conclusions The PIN1 gene expression may have - in future - an important meaning in the diagnostics of PTC and in understanding its

  15. Ultrasonography findings of thyroid metastasis in a patient with hepatocellular carcinoma: A case report

    International Nuclear Information System (INIS)

    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.

    Thyroid carcinoma is the most common endocrine malignancy, and papillary thyroid carcinoma represents the most common thyroid cancer. Papillary thyroid carcinomas that invade locally or metastasize are associated with a poor prognosis. We found that, during epithelial–mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1), papillary thyroid carcinoma cells acquired increased cancer stem cell-like features and the transcription factor paired-related homeobox protein 1 (...

    The occurrence and diagnosis of thyroglossal duct carcinoma is very rare. The synchronous occurrence of papillary carcinomas arising in a thyroglossal duct cyst (TGDC) and thyroid gland is extremely rare. Sistrunk's surgical technique must always be the initial treatment for a TGDC. However, if there is an intra-thyroidal carcinoma or local invasion, thyroidectomy has to be considered. Accurate pre-operative radiological evaluation should be performed in order to plan a surgical strategy. The aim of this report was to review our experience in the management of papillary thyroid carcinoma associated with TGDC. Our patient was a 67-year-old man who had a mural, micro- calcified nodule within a palpable, thick-walled cyst at the level of the hyoid and synchronously, a small macro-calcified mass in the isthmus of the thyroid gland.

  20. Stunning effects in radioiodine therapy of thyroid carcinoma. Existence, clinical effects and ways out

    International Nuclear Information System (INIS)

    In radioiodine therapy for malignant thyroid disease, the pre-therapeutically administered iodine-131-dose can reduce the potential of thyroid or thyroid carcinoma cells to absorb the following therapeutic iodine-131-dose, possibly leading to its failure. This so called stunning effect is controversially discussed in the scientific community. Here we summarize and evaluate publications with regard to the existence and the effects of stunning as well as possible countermeasures. (orig.)

    Full Text Available Research on medullary thyroid carcinoma (MTC over the last 55 years has led to a good understanding of the genetic defects and altered molecular pathways associated with its development. Currently, with the use of genetic testing, patients at high risk for MTC can be identified before the disease develops and offered prophylactic treatment. In cases of localized neck disease, surgery can be curative. However, once MTC has spread beyond the neck, systemic therapy may be necessary. Conventional chemotherapy has been shown to be ineffective; however, multikinase inhibitors have shown promise in stabilizing disease, and this year will probably see the approval of a drug (Vandetanib for advanced unresectable or metastatic disease, which represents a new chapter in the history of MTC. In this paper, we explore newly understood molecular pathways and the most promising emerging therapies that may change the management of MTC.

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

  6. Metastatic Differentiated Thyroid Carcinoma: Outcome On RAI-131 Therapy

    International Nuclear Information System (INIS)

    The aim of this study is to assess the variable grades of response of distant functioning thyroid metastases to serial radioactive iodine-131 therapy. One hundred fifty patients with metastatic differentiated thyroid cancer, mainly to lung and bone, were assessed to evaluate the therapeutic response of metastatic lesions to serial RAI-131 therapy regarding the site of metastases (bone or lung), type of response achieved (complete, partial, stable disease or disease progression) and patient survival. Out of 1368 patients with DTC, 150 patients (10.9%) had functioning distant metastases. The peak age of onset was between 40-59 years, 99 patients (66%) were females compared to 51 males (34%). 77 patients (51.3%) had papillary type while 73 patients (48.7%) had follicular type. Lung was the commonest site of metastases (62 patients, 41.4%) followed by bone (38 patients, 25.3%), bone and lung (32 patients, 21.3%) and other sites (18 patients, 12%). Metastases were more common at initial presentation or detected after the first therapy dose (118 patients, 78.7%) than during follow-up (32 patients, 21.3%). 25 patients (16.6%) achieved complete response, 52 patients (34.7%) showed partial response, 52 patients (34.7%) were in stationary state, and 21 patients (14%) showed evidence of disease progression. The overall survival from the detection of metastases was 71% at 5 years and 63% at 10 years. Up to the present time, radioiodine is the only available effective systemic therapy to treat patients with metastatic differentiated thyroid carcinoma (DTC) and for this reason, serial therapy doses are recommended for patient with metastatic DTC with favorable outcome and overall 5 and 10 year survival.

    2012-01-01

    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.

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

    International Nuclear Information System (INIS)

    The spontaneous food intake and nutritional status was assessed in 23 patients with small cell anaplastic carcinoma of the lung before and two times during a treatment period of 6 weeks. Radiation therapy was given for 2 weeks followed by a course of chemotherapy and another 2 weeks of radiation therapy. The energy intake decreased during the treatment from 146 to 130 per cent of basal metabolic rate (p>0.10). The protein intake remained unchanged (mean 0.9 g/kg body weight).There were insignificant and small losses of weight, body fat, free body mass and arm muscle circumference, and no changes were seen in serum albumin and serum transferrin. However, 6 patients suffered a weight loss of 5 per cent or more. No correlation existed between the nutritional parameters measured before treatment and the changes during treatment. Patients who suffered a loss of body weight could therefore not be singled out before the treatment. (orig.)

    Objective: To evaluate the relationship between the CT imaging features and pathologic findings of papillary thyroid carcinoma (PTC) and papillary thyroid microcarcinoma (PTMC), as well as the CT appearances of Non-papillary thyroid carcinoma(N-PTC). Methods: CT features of 229 PTC, 42 PTMC and 36 N-PTC patients with 264, 57 and 41 lesions respectively were analyzed retrospectively, and comparison was made with the pathologic findings. All data were analyzed by X2 test. Results: (1) Of PTC lesions, 25.4% (67/264)of the lesions and 2.9% (24/828) of metastatic lymph nodes showed cystic changes. Cyst formation with intracystic high density papillary-like nodules were found in 31.3% (21/67)of the PTC lesions and 37.5% (9/24) of metastatic lymph nodes. The histologic appearances of these tumors demonstrated fibrous tissue forming the wall of cyst, and papillary-like tumor tissue. (2) 75.2% (112/149) of PTC and 33.3% (5/15) of PTMC showed multiple small granular and fine calcifications, and there was statiscally significant difference between the two (P0.05). However, the degree of enhancement in PTC lesions were less than that of N-PTC, 36.6% (94/257) of PTC and 54.1% (20/37)of N-PTC lesions showed significant enhancement, and there was statistically significant difference (P<0.05). 75.1% of PTC (172/229) and 52.8% of (19/36)N-PTC had cervical lymph node metastases, with a propensity fbr PTC to have more VI region metastatic lymph nodes, 80.8% (139/172)vs 57.9% (11/19), which was statistically significant (both P<0.05). (4)Distant metastases to bone or lung were rare, but N-PTC (5/36) were more likely to produce distant metastases than PTC (5/229), and there was statistically significant difference (P<0.01). Conclusion Multiple, small granular and fine calcifications were found more frequently in PTC than PTMC. Compared with N-PTC, the papillary-like mural nodules of PTC showed less enhancement on post-contrast CT and cervical lymph node metastases were more frequently

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

    Prostate-specific membrane antigen (PSMA) is a type 2 transmembrane protein highly expressed in prostate cancer cells. We present the case of a 50-year-old man with metastatic papillary carcinoma of the thyroid, with rising thyroglobulin level and negative whole-body radioiodine scan after total thyroidectomy. Considering the limited treatment options available, it was decided to perform Ga-PSMA-HBED-CC PET/CT scan. It revealed intense radiotracer uptake in mediastinal and left supraclavicular lymph nodes, brain metastases, bilateral lung nodules, and skeletal sites. Patient also underwent F-FDG PET/CT. It demonstrated similar findings; however, the number of lesions detected in brain was less compared with Ga-PSMA PET/CT. PMID:26914556

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

    Hashimoto's thyroiditis is an inflammatory disease of the thyroid gland with autoimmune etiology. Patients afflicted with Hashimoto's have a higher risk of thyroid malignancies such as papillary thyroid carcinoma. In the present study, we investigated the frequency of papillary thyroid carcinoma......-polymerase chain reaction (RT-PCR) assay, we found messenger RNA (mRNA) expression for the RET/PTC1 and RET/PTC3 oncogenes in 95% of the Hashimoto's patients studied. All Hashimoto's patients presenting without histopathologic evidence of papillary thyroid cancer showed molecular genetic evidence of cancer. These...... data suggest that multiple, independent occult tumors exist in these patients at high frequency....

    To investigate clinical implications of FDG uptake in the thyroid glands in patients with advanced breast carcinoma by comparing metabolic and morphologic patterns on positron emission tomography (PET)/computed tomography (CT). The institutional review board waived the requirement for informed consent. A retrospective analysis was performed in 146 women (mean age 54 years) with advanced breast carcinoma who received systemic treatment. All patients underwent PET-CT before and after treatment. All PET-CT studies were reviewed in consensus by two reviewers. Morphologic changes including volume and mean parenchymal density of the thyroid glands were evaluated. Maximum standardized uptake value (SUVmax) and total lesion glycolysis (TLG) were determined to evaluate metabolic changes. These parameters were compared between patients with chronic thyroiditis who received thyroid hormone replacement therapy and those who did not. Of the 146 patients, 29 (20%) showed bilaterally diffuse uptake in the thyroid glands on the baseline PET-CT scan. The SUVmax showed a linear relationship with volume (r = 0.428, p = 0.021) and the mean parenchymal density (r = -0.385, p = 0.039) of the thyroid glands. In 21 of the 29 patients (72%) with hypothyroidism who received thyroid hormone replacement therapy, the volume, mean parenchymal density, SUVmax, and TLG of the thyroid glands showed no significant changes. In contrast, 8 of the 29 patients (28%) who did not receive thyroid hormone replacement therapy showed marked decreases in SUVmax and TLG. Diffuse thyroid uptake on PET-CT represents active inflammation caused by chronic thyroiditis in patients with advanced breast carcinoma. Diffuse thyroid uptake may also address the concern about subclinical hypothyroidism which develops into overt disease during follow-up. (orig.)

    Full Text Available Introduction. This is an extremely rare case of a patient with metastatic follicular thyroid cancer who continued to produce thyroid hormone and was iodine scan positive without stimulation after thyroidectomy and radioiodine (I-131 therapy. Patient Findings. A 76-year-old Caucasian male was diagnosed with metastatic follicular thyroid carcinoma on lung nodule biopsy. Total thyroidectomy was performed and he was ablated with 160 mCi of I-131 after recombinant human thyrotropin (rhTSH stimulation. Whole body scan (WBS after treatment showed uptake in bilateral lungs, right sacrum, and pelvis. The thyroglobulin decreased from 2,063 to 965 four months after treatment but rapidly increased to 2,506 eleven months after I-131. Thyroid stimulating hormone (TSH remained suppressed and free T4 remained elevated after I-131 therapy without thyroid hormone supplementation. He was treated with an additional 209 mCi with WBS findings positive in lung and pelvis. Despite I-131, new metastatic lesions were noted in the left thyroid bed and large destructive lesion to the first cervical vertebrae four months after the second I-131 dose. Conclusions. This case is exceptional because of its rarity and also due to the dissociation between tumor differentiation and aggressiveness. The metastatic lesions continued to secrete thyroid hormone and remained radioiodine avid with rapid progression after I-131 therapy.

  12. External radiotherapy in thyroid cancer

    International Nuclear Information System (INIS)

    In the management of thyroid carcinoma (TC) of any histological type, surgery is the primary mode of treatment. The second modality for the management is treatment with radioactive iodine (131I), especially, when the tumor has the ability to concentrate 131I. External radiotherapy has a limited use in differentiated thyroid carcinoma (DTC). It is useful in the management of bulky residual tissue which is not completely resected, metastatic disease which does not concentrated radioiodine and as a palliative treatment for reliving pain in patients with distant metastases. The ER as an adjuvant treatment in both anaplastic and medullary carcinoma has a significant role to play and should be used more frequently than is presently being advocated and practiced

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

    Anaplastic thyroid cancer (ATC) is an aggressive, fatal disease unresponsive to traditional therapies, generating a need to develop effective therapies. The PAX8/PPARγ fusion protein (PPFP) has been shown to favorably modulate tumor growth in follicular thyroid cancer, prompting our evaluation of its efficacy to inhibit ATC cell and tumor growth in vitro and in vivo. PPFP was constitutively expressed in five ATC cell lines: BHT-101, FRO, C-643, KTC-2 and KTC-3, and inhibited cell growth in four of five cell lines and xenograft tumor growth in four of four cell lines. PPFP-mediated growth inhibition involved multiple mechanisms, including upregulation of miR-122 and miR-375, associated with decreased angiogenesis and AKT pathway inactivation, respectively. Also, PPFP expression resulted in marked increase of thyroid-specific marker transcripts, including PAX8, thyroid peroxidase (TPO), sodium iodide symporter (NIS) and thyroglobulin, to varying degrees by activating their respective promoters, suggesting that PPFP induced cellular redifferentiation. Functional studies demonstrate that increased NIS messenger RNA is not associated with increased 125I uptake. However, ectopic expression of wild-type NIS-induced perchlorate-sensitive iodine uptake, suggesting that endogenous NIS in ATC cell lines is defective. As current treatment for ATC is only palliative, overexpression of PPFP may offer a novel therapeutic strategy for the treatment of ATC. PMID:23598436

    Full Text Available Abstract Introduction Well differentiated thyroid carcinoma with isolated involvement of skin is extremely rare. Presentation with a discharging sinus has not been reported. Case presentation This is a report of a 62 year old male patient with a long standing history of thyroid swelling which has metastasized to neck nodes and ulcerated over the midline resulting in a discharging sinus. Conclusion Extra thyroidal extension is seen in 4% to 16% of all well differentiated thyroid cancers. However there is only an isolated report of skin ulceration over the thyroid. This is a unique case where the ulceration resulted in a discharging sinus. Patient is alive after 2 years following successful therapy. Aggressive surgery is warranted for locally advanced thyroid cancer.

    Background and Rationale: Anaplastic thyroid cancer (ATC) is characterized by pleomorphic cells, has a poor prognosis, is highly devastating disease, and is not curable. No reliable biomarkers of metastatic potential, helpful for early diagnosis of ATC and therapeutic response have been found yet. Thrombospondin-1 (TSP-1) plays a fundamental role in cancer progression by regulating cell stromal cross-talk in the tumor microenvironment. Goals: Our goal was to understand whether TSP-1 could affect protein levels of its integrin receptors (e.g., ITGα3, α6, and β1) and cell morphology in BRAFV600E-ATC cells in vitro and in vivo. Experimental Design: Anaplastic thyroid cancer-derived cell cultures and western blotting were used to assess integrin protein expression upon TSP-1 silencing. Immunohistochemistry was performed on orthotopic primary human ATC and metastatic ATC in lung tissue to compare TSP-1 and integrin protein expression levels. Results: TSP-1 knock-down down-regulates ITGα3, α6, and β1 in BRAFV600E-human ATC cells. BRAFV600E-ATC cells with TSP-1 knock-down were rounded compared to control cells, which displayed a spread morphology. TSP-1 knock-down also reduced TSP-1, ITGα3, α6, and β1 protein expression levels in vivo in the ATC microenvironment, which is enriched in stromal and inflammatory cells. Conclusion: TSP-1 silencing causes changes in ITG levels and ATC cell morphology. The assessment of TSP-1 and ITG levels might contribute to earlier metastatic potential of BRAFV600E-positive aggressive thyroid cancers, and allow improved patient selection for clinical trials.

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

    2016-07-01

    Anaplastic astrocytoma (AA) is a diffusely infiltrating, malignant, astrocytic, primary brain tumor. AA is currently defined by histology although future classification schemes will include molecular alterations. AA can be separated into subgroups, which share similar molecular profiles, age at diagnosis and median survival, based on 1p/19q co-deletion status and IDH mutation status. AA with co-deletion of chromosomes 1p and 19q and IDH mutation have the best prognosis. AA with IDH mutation and no 1p/19q co-deletion have intermediate prognosis and AA with wild-type IDH have the worst prognosis and share many molecular alterations with glioblastoma. Treatment of noncodeleted AA based on preliminary results from the CATNON clinical trial consists of maximal safe resection followed by radiotherapy with post-radiotherapy temozolomide (TMZ) chemotherapy. The role of concurrent TMZ and whether IDH1 subgroups benefit from TMZ is currently being evaluated in the recently completed randomized, prospective Phase III clinical trial, CATNON. PMID:27230974

  2. Therapeutic implications of thymic uptake of radioiodine in thyroid carcinoma

    International Nuclear Information System (INIS)

    The management of 38 consecutive patients with differentiated thyroid carcinoma in the period 1991-1996, who each received at least one therapy dose of iodine-131, was reviewed, looking in particular at those in whom anterior mediastinal uptake was demonstrated on scans taken 3 and 7 days post-therapy. Such activity was noted in ten patients. On the basis of clinical follow-up, thyroglobulin measurement and radiological and other scintigraphic imaging, in nine of the ten patients the anterior mediastinal activity was attributed to physiological thymic uptake. Of those nine, all were under 50 years of age; seven were considered disease free, one had residual disease in the neck and one had distant metastases. Physiological uptake by the thymus was more prominent on the 7-day scans and in patients with low tumour volumes. For appropriate patient management it is essential to recognise that physiological uptake of 131I by the thymus in patients under 50 years of age is a potential cause of false-positive therapy scans.

  4. Size discrepancy between sonographic and pathological evaluation of solitary papillary thyroid carcinoma

    International Nuclear Information System (INIS)

    Background: Sonographic size of suspicious thyroid lesions is an essential parameter in the evaluation of thyroid nodules, determining the need for needle biopsy and has impact on the extent of surgery. Limited data is available on the correlation between the size of the thyroid nodule on sonography and the actual size measured during histological examination. The aim of the present study was to compare these two modalities and to discuss the potential clinical implications of the findings in the study population. Methods: The database of Rabin Medical Center was reviewed for all patients with histologically proven papillary carcinoma of the thyroid treated by thyroid surgery between 2005 and 2010. Results: 292 patients with papillary thyroid carcinoma were included. The mean sonographic size of the nodule was 2.19 ± 1.15 cm. The mean pathological diameter was 1.69 ± 1.09 cm. Discrepancies between tumor histological diameter and the sonographically measurement were more prominent in tumors larger than 1.5 cm. Nonetheless, 18.8% of thyroid nodules that were measured by US as larger than 1 cm, were found to be smaller than 1 cm on final pathology. Similarly, 7.2% of nodules evaluated by sonography were determined as being larger than 4 cm, while their definitive size was smaller than 4 cm. Conclusions: We noted a significant discrepancy between the preoperative sonographic and the pathologic size measurements for papillary thyroid carcinoma. The sonographic evaluation misclassifies both patients with small and large thyroid tumors, and consequently exposes them to unnecessary workup and more extensive operation. This discrepancy between the ultrasound findings and actual tumor size should be taken into account in clinical practice and help guide the evaluation and treatment of patients with thyroid nodules

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

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

  9. Thyroid adenomas and carcinomas following radiotherapy for a hemangioma during infancy

    International Nuclear Information System (INIS)

    Background and purpose: 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. Methods and materials: Of a total of 8307 patients treated for a skin hemangioma between 1940 and 1973 at the Institut Gustave-Roussy, 4767 were included in an incidence study, among whom 3795 had received radiotherapy. Seventy-three percent were less than 1-year-old at the time of treatment. External radiotherapy, Radium 226, Strontium 90, Yttrium 90, and Phosphorus 32 were used. The radiation dose received by the thyroid during radiotherapy, estimated in 3497 of the 3795 patients using specific software, was 41 mGy on average. Thyroid tumor cases were obtained by sending out a questionnaire, and were verified in pathological reports. Estimates of thyroid cancer specific incidence rates in the French population were obtained from the French cancer registry network. External and internal analyses were performed. Results: During an average follow-up of 35 years, 11 patients developed a differentiated thyroid carcinoma and 44 a thyroid adenoma. The incidence of thyroid adenoma was found to be higher among taller and heavier individuals. The incidence of both thyroid carcinoma and adenoma was higher among non-smoker patients. A significant dose-response relationship was found between the radiation dose received by thyroid and the risk of thyroid cancer (Excess Relative Risk per GY, ERR/Gy: 14.7, 95%CI: 1.6-62.9) and of adenoma (ERR/Gy: 5.7, 95%CI: 0.7-19.4). Conclusion: 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

    A chromosomal translocation results in production of an oncogenic PAX8-PPARG fusion protein (PPFP) in thyroid carcinomas. PAX8 is a thyroid transcription factor, and PPARG is a transcription factor that plays important roles in adipocytes and macrophages. PPFP retains the DNA binding domains of both proteins; however, the genomic binding sites of PPFP have not been identified, and only limited data exist to characterize gene expression in PPFP thyroid carcinomas. Therefore, the oncogenic func...

  15. Potential diagnostic utility of CD56 and claudin-1 in papillary thyroid carcinoma and solitary follicular thyroid nodules

    International Nuclear Information System (INIS)

    Aim: The pathological diagnosis of papillary thyroid carcinoma (PTC) is usually easily achieved. However distinguishing the follicular variant of papillary carcinoma (FVPC) from other follicular thyroid lesions is an area of controversy. In this study we investigated the role of CD56 and claudin-1 in the discriminating the FVPCs from other solitary follicular patterned nodules. We also evaluated the application of these two markers in reclassifying the controversial cases of the well differentiated tumors of unknown malignant potential (WDTs-UMP). Materials and methods: The immunohistochemical expression of CD56 and claudin-1 was evaluated in 86 samples of thyroid lesions together with 10 samples of normal thyroid tissue. Thyroid lesions included: 29 PTCs [classic papillary carcinoma (n = 13) and FVPC (n = 16)], 47 solitary follicular patterned nodules [follicular adenomas (n = 12), hyperplastic nodules (n = 32) and follicular tumor of unknown malignant potential (n = 3)] and 10 WDTs-UMP. Results: The statistical analysis showed significantly different expressions of each of CD56 and claudin-1 in the FVPCs versus other solitary follicular patterned nodules. Claudin-1 sensitivity (100%) was higher than CD56 sensitivity (81.3%). However claudin-1 specificity (80.9%) was < CD56 specificity (89.4%). The combined use of CD56 and claudin-1 (claudin-1 +/CD56-) showed specificity (100%), positive predictive value (100%) and sensitivity (81.3%) in the differentiation between the FVPCs and other follicular nodules. In the light of this statistical outcome, 5/10 cases of WDTs-UMP expressing the (claudin-1 +/CD56-) panel could be rediagnosed as PTC. Conclusion: Combined utility of CD56 and claudin-1 is helpful in diagnosing the FVPC and its differentiation from other follicular patterned nodules. Application of these two markers may greatly aid in the reevaluation of the WDTs-UMP and interpretation of their expected behavior

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

    Full Text Available 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.

    2010-07-01

    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.

    In 40 patients with laryngeal carcinoma after total laryngectomy and radiotherapy the triiodotyronine binding index, total thyroxine level, serum free thyroxine index were determined before, during and after treatment. At the same time thyroid iodine uptake was determined by the routine method. Surgical treatment as well as radiotherapy caused lowering of thyroid functions. These changes had a high tendency for return to normal values, not earlier, however, than 6 months after treatment. The authors stress that endocrine thyroid disturbances may have an important influence on delay of psychic rehabilitation and speech training in laryngectomized patients. (author)

Posterior whole body scanning (WBS) with I-131 showed presence of the abnormal iodine uptake tissue localized in the cervical, hepatic and pulmonary regions. The patient remained for a large period without follow-up or specific therapy. During that period she developed palpable cervical nodules, with consequent return to the endocrinology service. She was submitted to a new scintilographic studies with I-131, realized in our institution where, first was studied the anterior cervical region, using the dosage of 0,100 mCl, in a Tomographic Digital Gamma-Camera, type Elscint, model SPX-6, pinhole collimator. The images showed a discrete diffuse raising of uptake in this region, without definition of high uptake focal areas. In the propedeutic follow-up a WBS with I-131 was realized (dosage of 0,5Ci), using the same equipment and a high-energy collimator. The images were acquired 48h after the oral administration of radioiodine, revealing presence of anomalous iodine uptake tissue in the anterior cervical region, lungs, cranium (parietal bones) and low abdomen. After 7 days, she was submitted to the radio-iodine-therapy in the dosage of 150 mCi, staying isolated in a therapeutic room until to reach values equal or lower than 1.11Gbq(30mCi). Therapeutic post-dosage WBS has not revealed new metastatic areas, even in high dosage.

    Background Medullary thyroid carcinoma (MTC) is a rare malignant tumour and usually difficult to diagnose with ultrasound. The aim of the study is to summarize the sonographic features of MTC and evaluate their diagnostic values.Methods We analyzed the sonographic features of 35 MTCs and 50 benign nodules with respect to nodular size,echogenecity, internal content, shape, height/width, border, peripheral halo, calcifications and colour flow pattern. The ratio of long to short axis, echogenecity, internal content and calcifications were also assessed in cervical lymph nodes.The differences in sonographic features between MTCs and benign nodules were analyzed with Chi square test. The diagnostic efficiency of each sonographic feature was determined.Results The main sonographic features of MTC were hypoechogenicity (including marked hypoechogenicity) (n=34,97%), internal solid content (n=29, 83%), taller than wide (n=34, 97%), well defined border (n=24, 69%),microcalcifications or macrocalcifications (n=23, 66%). The echogenicity, internal content, shape, peripheral halo and calcifications were significantly different between these two groups, while the tall/wide, border, and pednodular and intranodular vascularisation were not significantly different. Among all the individual sonographic features, irregular shape had the highest diagnostic efficiency with a sensitivity of 51% and specificity of 92%. The combination of marked hypoechogenicity, microcalcifications, and irregular shape yielded a sensitivity of 77% and specificity of 86%.Conclusions The typical sonographic features of MTC are hypoechogenicity, predominantly solid, irregularly shaped with intranodular micro- or macro-calcifications. The combination of multiple sonographic features is helpful, but not definitive, for the diagnosis of MTC.

    2016-06-01

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

MÉTODOS: Análise retrospectiva dos dados de 38 pacientes submetidos à tireoidectomia por carcinoma folicular puro, num período de 10 anos no HC-FMUSP. O tempo médio de seguimento foi de três anos e três meses. Nove pacientes eram do sexo masculino (23,7% e 29 do sexo feminino (76,3%, com idades entre 19 e 87 anos (média=49,5. RESULTADOS: Em 17 (58,6% dos doentes, observou-se nódulo único à ultra-sonografia, e 23 (79,3% tinham nódulos frios à cintilografia. Sintomatologia esteve presente em 33 pacientes (86,8%. A punção aspirativa por agulha fina (PAAF, realizada em 27 pacientes, revelou padrão folicular em 24 (88,9%, carcinoma papilífero em 2 (7,4% e bócio em 1 (3,7%. Tireoidectomia total foi o tratamento final em 34 pacientes e esvaziamento cervical foi realizado em três casos. Apenas 5 (13,1% obtiveram confirmação diagnóstica ao exame de congelação intra-operatória. Houve 2 (5,2% óbitos pela doença e 5 (13,1% pacientes apresentam-se vivos com doença. O aumento da tireoglobulina (TG correlacionou-se com o aparecimento de metástase em 100% dos casos. CONCLUSÕES: Concluímos que pacientes com carcinoma folicular de tireóide geralmente apresentam-se com nódulo único ou predominante ao primeiro exame, cuja PAAF é de padrão folicular. O exame de congelação raramente confirma o diagnóstico. Em nosso serviço, o tratamento de escolha é a tireoidectomia total, permitindo um seguimento mais adequado e confiável do paciente e prevenindo o crescimento de lesões subclínicas no lobo contralateral. A evolução geralmente é favorável.BACKGROUND: Unlike papillary carcinoma, there are limited data regarding diagnosis, treatment and follow-up of patients with follicular thyroid carcinoma.

  19. Factor analysis in thallium-201 chloride thyroid studies

    International Nuclear Information System (INIS)

    Factor analysis was applied to thyroid thallium-201 imaging to get separated image of tumor from normal thyroid tissue. Thirty-eight patients with various thyroid tumors which were histologically confirmed were included in this study. Following intravenous injection of 111 MBq (3 mCi) of 201Tl chloride, thyroid images in 64 frames were taken for 30 to 60 minutes using Toshiba gamma camera system and data were analyzed by 2 or 3 factor analysis. In 28 of 38 patients separated images of the lesions from normal thyroid were obtained and time-activity curves of various shapes corresponding to the lesions were also obtained. When the curves were classified into 3 groups according to their shapes, increasing flat and decreasing, follicular carcinoma did not show increasing shape whilst neither of papillary carcinoma, squamous cell carcinoma and anaplastic carcinoma showed decreasing shape. The shapes of the curves were thought to be reflected in clearance of the agent from the lesions. Factor analysis in 201Tl chloride thyroid scan provided separated image of tumor from normal thyroid gland automatically and the obtained curves corresponding to the lesions provided information for estimating the characteristics of thyroid tumors.

  20. Clinical Study on Thyroid Cancer (The 3rd Report)

    International Nuclear Information System (INIS)

    Clinical features of 406 patients with histologically verified thyroid carcinomas were investigated from May, 1978 to April, 1985 at the Seoul National University Hospital with the following results. 1) The incidence of thyroid cancer according to their histological classification was 79. 8% of papillary carcinoma, 14.5% of follicular carcinoma, 1.5% of medullary carcinoma, 2.2% of anaplastic carcinoma, 2 cases of squamous carcinoma and 3 cases of lymphoma. 2) The age distribution showed the peak incidence in the fourth decade (25.1%), followed by the fifth and the third decade. 3) The ratio of male to female patients was 1:6.1. The ratio is 1:5.9 in papillary carcinoma and 1:8.8 in follicular carcinoma. 4) The mean age was 40.2 year in papillary carcinoma, 37.4 year in follicular carcinoma, 36.5 year in medullary carcinoma, 60.3 year in anaplastic carcinoma, 62.0 year in squamous carcinoma, 59.7 year in lymphoma. 5) The diameter of the thyroid masses was smaller than 1.5 cm in 19.9% of the patients, from 1.5 cm to 5 cm in 50.5%, from 5 cm to 10 cm in 25.4% and larger than 10 cm in 25.4%. 6) Metastasis to the regional lymph nodes at diagnosis was noted in 44.2% of total patients, and distant metastasis was 5%, and local infiltration was 44.2%. 7) The clinical staging was revealed 42.1% of the patients in stage I, 9.1% in stage II, 35.7% in stage III, 5.2% in stage IV, and 7.9% in undetermined stage.

    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.

    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.

  5. Benign oral pathology as a cause of false positive 131I uptake in thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: We present three thyroidectomised patients with a history of thyroid carcinoma who had non-metastatic 131I uptake due to benign oral pathology. A salivary gland study suggested impaired function but no obstruction was demonstrated on a sialogram. The symptoms resolved on antibiotic therapy and a subsequent 131I study was normal. A subsequent thallium study demonstrated physiological tracer distribution. A 35-year-old female with papillary cell carcinoma of the thyroid demonstrated a focus of uptake on the right hemi-mandible following both a diagnostic and a therapeutic dose of 131I. This area was tender and an OPG confirmed an area of liquefaction at this site. A 53-year-old female with medullary cell carcinoma of the thyroid demonstrated a focus of uptake in the right side of the maxilla following a diagnostic administration of 131I. An OPG confirmed an area of liquefaction around the apex of the right upper centre. These three cases illustrate salivary gland and dental inflammation as causes of false positive 131I uptake. It is important to differentiate non-metastatic 131I uptake from that due to functioning metastatic thyroid carcinoma in order to avoid inappropriate treatment with large additional doses of 131I. As in these patients, clinical assessment and the use of anatomical imaging or other isotopes such as thallium or technetium can be helpful in ruling out a mistaken diagnosis of metastasis

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

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

  12. Isolated skeletal muscle metastatic deposit in a patient with micropapillary carcinoma thyroid identified by 18F FDG PET CT

    International Nuclear Information System (INIS)

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

  13. Medullary carcinoma of the thyroid: Claudius-Regaud center's experience

    International Nuclear Information System (INIS)

    From June 1971 to September 1989, 38 patients had been treated for medullary carcinoma of the thyroid (MCT). Four patients were excluded from the study, because they were rapidly lost of follow up. We have distinguished three groups: i) group 1 (infra-clinic tumor diagnosed at the time of family investigation): four cases treated by radical thyroidectomy and bilateral cervical evidement; ii) group 2 (bulky cervical tumor with metastatic spread): three patients treated with a palliative intent; iii) group 3 (bulky cervical tumor with metastatic spread): 27 patients treated by thyroidectomy (with cervical lymph mode dissection in 23 cases) and post-operative radiotherapy for 20 patients who had histopathologic invading nodes or a large extracapsular spreading. All patients from the group 1 are alive free of recurrence and the median follow up time is 35 months. In group 2: two patients died from the disease three and 10 months after initial therapy and one patient is alive with disease after 72 months of follow up. In group 3: median follow up time is 79 months. Ten patients (37%) had a local and locoregional failure (isolated nodal recurrence: three patients local and/or nodal relapse with metastatic failure: seven patients). For teen per cent of the irradiated patients relapsed in the target volume. Nine patients (33%) had a metastatic relapse without evidence of cervical recurrence. Median period of metastatic recurrence is 47 months. Specific survival and disease free survival of 65 and 45% at 5 years, 54 and 26% at 10 years respectively. From nine prognosis parameters considered, the post-therapy increasing of tumor markers (thyrocalcitonin and/or CE/A) had significant influence on disease free survival (P<0.02). Histological nodal status had no significant influence on actuarial metastatic rate, but 93% of metastatic patients were N+, and 65% of patients with N+ became M+. This study confirms that metastatic dissemination in patients with nodal invading is a

  14. Scintigraphic and ultrasonographic appearance in different tumor stages of thyroid carcinoma

    International Nuclear Information System (INIS)

    Scintigraphy is routinely used in evaluating thyroid nodules. Functioning nodules are reported to have a low probability of being malignant. Therefore cancer should appear hypofunctioning or 'cold' on scintiscan. The aim of the study was to compare the scinitgraphic pattern in different tumor stages of thyroid carcinoma. In addition, sonographic results are evaluated. In 151 patients with thyroid carcinoma 99mTc-pertechnetate scans were evaluated retrospectively by a visual inspection scoring method (A = no significant uptake to D = nodular uptake superior to normal thyroid tissue). Planar images were taken using a small field thyroid gamma camera. There were 52 patients with pT1 carcinoma (2 x follicular and 50 x papillary). The mean tumor size was 0.56 ± 0.26 cm. The scintigraphic results were A and B in 5.7 % (n = 6), C in 73 % (n = 38), D in 15.6 % (n = 8). Out of 40 patients with pT2 carcinoma, 34 had a papillary, 6 a follicular histology. Mean tumor size was 1.66 ± 0.49 cm. The scintiscan was A in 12.5 % (n = 5), B in 32.5 % (n = 13), C in 42.5 % (n = 17) and D in 12.5 % (n = 5). There were 11 patients with pT3 carcinoma (4 x papillary, 7 x follicular). The mean tumor size was 3.96 ± 0.88 cm in diameter. Scintiscan was A in 72.7 % (n = 8), C in 27.3 % (n = 3). Among 48 patients with pT4 carcinoma (2 x follicular, 1 x nondifferentiated, 45 x papillary), scan was A in 41.6 % (n = 20), B in 14.57 % (n = 7), C in 33.3 % (n = 16) and D in 10.4 % (n = 5). Mean tumor size was 2.16 ± 1.45 cm (7 carcinomas ≤ 1 cm, 23 x 1 - 2 cm, the remaining > 2 cm). Tumor size plays an important role in routinely used planar scintigraphy. Nodules greater than 2 cm in diameter tend to appear cold but microcarcinomas (≤ 1 cm) are often indifferent on scan. Therefore, planar 99mTc-pertechnetate scintigraphy is of little value in evaluating small thyroid nodules. In order to diagnose small thyroid nodules, ultrasonography and ultrasonographically guided FNAB should be

    Purpose The importance of long noncoding RNAs (lncRNAs) in tumorigenesis has recently been demonstrated. However, the role of lncRNAs in development of thyroid cancer remains largely unknown. Materials and Methods Using quantitative reverse transcription polymerase chain reaction, expression of three lncRNAs, including BRAF-activated long noncoding RNA (BANCR), papillary thyroid cancer susceptibility candidate 3 (PTCSC3), and noncoding RNA associated with mitogen-activated protein kinase pathway and growth arrest (NAMA), was investigated in the current study. Results Of the three lncRNAs (BANCR, PTCSC3, and NAMA), expression of BANCR was significantly up-regulated while PTCSC3 and NAMA were significantly down-regulated in papillary thyroid carcinoma (PTC) compared to that in normal tissue. BANCR-knockdown in a PTC-derived cell line (IHH-4) resulted in significant suppression of thyroid stimulating hormone receptor (TSHR). BANCR-knockdown also led to inhibition of cell growth and cell cycle arrest at G0/G1 phase through down-regulation of cyclin D1. In addition, BANCR was enriched by polycomb enhancer of zeste homolog 2 (EZH2), and silencing BANCR led to decreased chromatin recruitment of EZH2, which resulted significantly reduced expression of TSHR. Conclusion These findings indicate that BANCR may contribute to the tumorigenesis of PTC through regulation of cyclin D1 and TSHR. PMID:26323637

    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.

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

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

    Full Text Available A rare case of extra medullary plasmacytoma (EMP of thyroid gland in a 60 year old male, occurring against a background of Hashimoto′s thyroiditis is reported. The fine needle aspiration cytology (FNAC initially done as an outpatient procedure, showed atypical epithelial cells on a background of amyloid. Considering these findings we gave a diagnosis of medullary carcinoma. Histology of the total thyroidectomy specimen showed an extensive infiltration of neoplastic plasma cells against a background of Hashimoto′s thyroiditis, with a bizarre Hurthle cell change. Immunohistochemistry on the histology sections confirmed the diagnosis of solitary plasmacytoma of thyroid against a background of Hashimoto′s thyroiditis.

    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.

  3. Kinetic behaviour of radioiodines accumulating in recurrent thyroid carcinomas and their metastases and the role of substituted thyroid hormones during radioiodine treatment

    International Nuclear Information System (INIS)

    The relationship between the kinetic behaviour of radioiodines accumulating in recurrent thyroid tumours or their metastases and the role of substituted thyroid hormones was examined in 2 groups of patients undergoing radioiodine treatment, one of which additionally received thyroid hormones, while no such treatment was carried out in the other one. Two computer-assisted, whole body scintiscan studies (days 2 and 4) were performed so as to permit quantitative evaluation of the region of interest. The effective half-lives derived from this this procedure were longer for the patients receiving no thyroid hormones, pointing to a more beneficial effect of radioiodine treatment in this group. This leads to the conclusion that in patients receiving radioiodine therapy in order to control the spread of thyroid carcinomas, thyroid hormones should not be substituted until the cessation of this treatment.

  4. DNA Methylation in Thyroid Tumorigenesis

    International Nuclear Information System (INIS)

    Thyroid cancer is the most common endocrine cancer with 1,690 deaths each year. There are four main types of which the papillary and follicular types together account for >90% followed by medullary cancers with 3% to 5% and anaplastic carcinomas making up <3%. Epigenetic events of DNA hypermethylation are emerging as promising molecular targets for cancer detection. Our immediate and long term goal is to identify DNA methylation markers for early detection of thyroid cancer. This pilot study comprised of 21 patients to include 11 papillary thyroid cancers (PTC), 2 follicular thyroid cancers (FTC), 5 normal thyroid cases, and 3 hyperthyroid cases. Aberrant promoter methylation was examined in 24 tumor suppressor genes using the methylation specific multiplex ligation-dependent probe amplification (MS-MLPA) assay and in the NIS gene using methylation-specific PCR (MSP). The frequently methylated genes were CASP8 (17/21), RASSF1 (16/21) and NIS (9/21). In the normal samples, CASP8, RASSF1 and NIS were methylated in 5/5, 4/5 and 1/5 respectively. In the hyperthyroid samples, CASP8, RASSF1 and NIS were methylated in 3/3, 2/3 and 1/3 respectively. In the thyroid cancers, CASP8, RASSF1, and NIS were methylated in 9/13, 10/13, and 7/13 respectively. CASP8, RASSF1 and NIS were also methylated in concurrently present normal thyroid tissue in 3/11, 4/11 and 3/11 matched thyroid cancer cases (matched for presence of both normal thyroid tissue and thyroid cancer), respectively. Our data suggests that aberrant methylation of CASP8, RASSF1, and NIS maybe an early change in thyroid tumorigenesis regardless of cell type

  6. Thyroid Hormone Deiodinases and Cancer

    Full Text Available Deiodinases constitute a group of thioredoxin-containing selenoenzymes that play an important function in thyroid hormone homeostasis and control of thyroid hormone action. There are three known deiodinases: D1 and D2 activate the pro-hormone thyroxine (T4 to T3, the most active form of thyroid hormone, while D3 inactivates thyroid hormone and terminates T3 action. A number of studies indicate that deiodinase expression is altered in several types of cancers, suggesting that (i they may represent a useful cancer marker and/or (ii could play a role in modulating cell proliferation - in different settings thyroid hormone modulates cell proliferation. For example, although D2 is minimally expressed in human and rodent skeletal muscle, its expression level in rhabdomyosarcoma (RMS-13 cells is 3-4 fold higher. In basal cell carcinoma (BCC cells, sonic hedgehog (Shh-induced cell proliferation is accompanied by induction of D3 and inactivation of D2. Interestingly a 5-fold reduction in the growth of BCC in nude mice was observed if D3 expression was knocked down. A decrease in D1 activity has been described in renal clear cell carcinoma, primary liver cancer, lung cancer, and some pituitary tumors, while in breast cancer cells and tissue there is an increase in D1 activity. Furthermore D1 mRNA and activity were found to be decreased in papillary thyroid cancer while D1 and D2 activities were significantly higher in follicular thyroid cancer tissue, in follicular adenoma and in anaplastic thyroid cancer. It is conceivable that understanding how deiodinase dysregulation in tumor cells affect thyroid hormone signaling and possibly interfere with tumor progression could lead to new antineoplastic approaches.

    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.

    Objective:The aim of the study was to investigate the relationship between expressions of estrogen receptor (ER), progesterone receptor (PR) and gender, age, tumor size, lymph node metastasis, capsular invasion and histological type of dif erentiated thyroid carcinoma (DTC). Methods:Seventy cases of DTC who received surgery in our hospital (No. 401 Hospital of People’s Liberation Army, Qingdao, China) between January 2008 and December 2011 were selected. Among them, 61 cases were papil ary carcinoma and 9 cases were fol icular carcinoma. Twenty cases were normal thyroid tissue adjacent to the tumor which was used as control. Immunohistochemical SP method was employed to detect the expression of ER and PR. Results:The positive rates of ER and PR in tumor tissues of DTC patients were 21.4%(15/70) and 31.4%(22/70), respectively, and no expression of ER or PR were founded in normal thyroid tissue (P0.05) of DTC patients. Conclusion:The expression levels of ER and PR in the tumor tissue of DTC patients were higher than those in the normal thyroid tissue nearby the tumor. Therefore, ER and PR expression might be clinical markers for DTC and its prognosis.

    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.

    Thyrotropin (TSH) suppression therapy using thyroid hormone plays an important role in the management of patients thyroidectomized for differentiated thyroid cancer. The rationale for TSH suppression is that differentiated thyroid cancer cells have TSH receptors and show increased adenylate cyclase activity following TSH exposure. L-thyroxine is used for long-term therapy. L-triiodothyronine is preferred when suppressive therapy must be discontinued for radioiodine scan, since its shorter half-life allows more rapid increases of TSH levels. The assessment of TSH suppression is still uncertain. The development of second and third TSH assay generations with progressive improvement in sensitivity has made the TRH test unnecessary and has raised the issue of the TSH level indicative of TSH suppression. In clinical practice TSH values below 0.1 mU/L are considered compatible with appropriate TSH suppression. Serum thyroglobulin is a reliable marker of metastatic disease after total surgical and radioiodine ablation of the thyroid gland and it is useful in the surveillance of patients with differentiated thyroid cancer.

  12. Aftercare of malignant thyroid growth

    International Nuclear Information System (INIS)

    The 'standard programme of aftercare for patients with malignant thyroid growths' practised in our department comprises the following measures: - Searching for residual tissues and recurrences in the neck/throat region and for metastases by means of physical examination, scintigraphy, x-ray diagnosis and laboratory tests (including determination of tumour markers); - monitoring and treatment of side effects by thyroidectomy (recurrent paresis, parathyroprival tetany); - prevention, detection and treatment of side effects of high-dosed radio-iodine therapy (on salivary glands and bone marrow) or those of cytostatic treatment (on heart muscle and bone marrow); - monitoring substitutive and suppressive treatment with thyroxines; - psychological guidance and genetic counselling. Corresponding to therapeutic approach, the overall aftercare programme is aimed primarily at papillary and follicular carcinoma and C-cell carcinoma. However, aftercare is hardly effective with anaplastic carcinoma owing to its persistently bad prognosis and its 50% survival time of some three months. (orig./MG)

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

    The aim is to study the incidence of thyroid cancer in surgically treated nodular thyroid disease, clinicopathological characteristics and treatment results. A retrospective review of 45 patients with thyroid malignancy at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia during a 3-years period between January 2000 through to December 2003 was carried out. Analysis of clinicopathologic characteristics, age correlation to different risk factors, outcome of surgery and radioiodine treatment. A total of 120 thyroidectomies were performed during the 3-years period, January 2000 through to December 2003 at King Abdul-Aziz University Hospital. Forty-five (37.5%) patients had histopathology confirmed diagnosis of thyroid cancer. Eighty-two point two percent cases of papillary carcinoma, 4.4% follicular type and 6.7% anaplastic and medullary carcinoma of thyroid. Mean age was 40.5 +/- 14.8 years. Male preponderance was seen in this study with males: females ratio is 1.1:1. Nodular goiter was the most frequent presentation, observed in 30 (66.7%) cases. Fine needle aspiration cytology was suggestive of malignancy in 76% of cases. Ninety-seven patients with papillary carcinoma received ablative dose of radioiodine with average dose of 100-200 mCi. One female patient with follicular carcinoma of thyroid with bone, lung, and brain metastases received 4 doses of radioiodine with total dose of 800 mCi. Mortality rate was (2.2%), one patient died of complication of invasive anaplastic carcinoma with invasion of the trachea. There is a lot of controversy regarding thyroid malignancy investigations and management. We recommend that thyroid cancer patients should be treated by a team of endocrinologist, pathologist, experience thyroid surgeon, nuclear medicine and external radiotherapy physician to achieve an optimum care and good prognosis.

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

    Apoptosis plays a pivotal role in development, tissue homeostasis, cancer, immune defense, and response to weightlessness. It can be initiated by external signals via death receptors, but may also emerge from mitochondria. We exposed mitochondria-rich thyroid carcinoma cells (ONCO-DG1 cell line) and normal thyroid cells (HTU-5) to conditions of simulated microgravity. After 24 h, 10% of the cancer cells had entered a Fas-dependent apoptotic pathway, but destruction and redistribution of mitochondria, microtubuli disruption, and caspase-3 activation were also detected, demonstrating the activation of extrinsic as well as intrinsic pathways. Furthermore, ONCO-DG1 cells grown on the clinostat showed elevated amounts of Bax, but reduced quantities of bcl-2. In addition, signs of apoptosis became detectable, as assessed by terminal deoxynucleotidyl transferase-mediated dUTP digoxigenin nick end labeling, 4',6-diamidino-2-phenylindole staining, and 85-kDa apoptosis-related cleavage fragments. These fragments resulted from enhanced 116-kDa poly(ADP-ribose)polymerase activity and apoptosis. Apoptosis was also detected in normal HTU-5 cells, as demonstrated by electron microscopy, activation of caspase-3, increases in Fas and Bax, and elevation of 85-kDa apoptosis-related cleavage fragments resulting from enhanced poly(ADP-ribose) polymerase activity. Gravitational unloading affects the mitochondria and thereby may trigger apoptosis in thyroid cells subjected to weightlessness by clinorotation. PMID:12933692

    Full Text Available Abstract Introduction The parotid gland and the great cervical veins are very rarely involved in a metastatic thyroid cancer. Case presentation We report an interesting case of an unusual metastasis of a thyroid follicular carcinoma including the histopathological and radiological findings. A woman was seen in the otolaryngology clinic with a mass at the angle of the left side of her jaw. Clinical examination and investigations confirmed a thyroid follicular carcinoma with metastases to the parotid gland and the internal jugular vein. Conclusion This is an educational case which highlights the importance of close communication between clinicians, histopathologists and radiologists to ensure that such rare cases are not missed.

  2. Hypofractionated radiation therapy for invasive thyroid carcinoma in dogs: a retrospective analysis of survival

    International Nuclear Information System (INIS)

    Thirteen dogs with invasive thyroid carcinoma (WHO classification T2b or T3b) seen between January 1991 and October 1997 were treated by external beam Irradiation. Four once-weekly fractions of 9 gray of 4 MeV X-rays were administered. Four of the dogs died of progression of the primary disease and four from metastatic spread. Of the remaining dogs, three died of unrelated problems, although two were still alive at the time of the censor. Kaplan-Meier analysis of the survival time from first dose to death from either primary or metastatic disease gave a median survival time of 96 weeks (mean 85 weeks, range six to 247 weeks). Radiographic evidence of pulmonary metastatic disease at presentation had no prognostic value whereas crude growth rate was a highly significant factor. The present series Indicates that radiation therapy should be considered an important modality for the control of invasive thyroid carcinoma in the dog

  3. Seric thyroglobulin behavior in thyroid carcinoma patients treated with 131I

    International Nuclear Information System (INIS)

    The thyroid carcinomas, mainly the differentiated ones, for involving originally young patients and for showing relatively benign course, require a long term follow-up. So, every new available method that may be useful for the follow-up of these patients soon becomes very important. The advent of radioimmunoassay made the determination of thyroglobulin seric levels possible and this practice has been incorporated into medical routine in the past few years. The analysis of the results permit to conclude that the administration of 131I therapeutic dose to differentiated and medular thyroid carcinoma patients is followed by imediate and transitory rise in circulating thyroglobulin levels. It denotes immediate effect of the 131I that can be observed in a short period of time independently of L-T3 administration and endogen TSH levels. After this period the thyroglobulin is at least in a partial way, TSH-dependent. (author)

  4. FDG PET and alternative imaging in the management of thyroid carcinoma

    International Nuclear Information System (INIS)

    Differentiated carcinoma of the thyroid are one of rare malignancies that is associated with excellent prognosis. Follow-up with regular thyroglobulin assay and 131I whole-body scan is capable of detecting residual or recurrent disease with great sensitivity and specificity. However, there is overwhelming evidence to suggest that this approach is not fail-safe due to increasing reports of false negative and false positive results, which may result in missed or unwarranted therapy with 131I. This article will review the current management of differentiated carcinoma of the thyroid and the possible causes of the reported inadequacy of thyroglobulin and 131I whole-body scan to detect residual or recurrent disease, and the increasing role of alternative imaging, particularly 18F-FDG PET in the management of this curable malignancy.

  5. Bone scintigraphy in the follow-up of thyroid carcinoma patients

    International Nuclear Information System (INIS)

    In patients with bone metastases of papillary or follicular thyroid carcinomas (n=23 and n=92, resp.) a retrospective study is conducted to find out whether the follow-up requires bone scintigraphy to detect bone metastases. Although there was no case of primary diagnosis of bone metastases established by bone scintigraphy, further bone focusses that had not been detected by I-131-whole body scintigraphy nor by whole body radiology were found in 24 patients by bone scintigraphy. Bone scintigraphy is of no use if applied as a routine to follow-up tumor patients with papillary of follicular thyroid carcinomas, but it is necessary if clinical findings, tumor markers, I-131 scans or X-rays suggest the occurence of metastases.

    Full Text Available A 58-year old man, affected by metastatic thyroid carcinoma, experienced a progressive bilateral visual impairment. Ophthalmic examination revealed the presence of a choroidal mass with an associated exudative retinal detachment in both eyes. Twelve years before, a diagnosis of metastatic thyroid carcinoma had been established and the patient had been subject to several therapeutic procedures. In May 2007, he received a radiotherapy treatment to the left eye with an episcleral plaque and bilateral bulbar injection of bevacizumab. The patient had a rapid and stable visual acuity recovery. Twenty months after treatment, the lesion treated with radiotherapy was still stable whereas the contra-lateral lesion had evolved and determined a vitreal hemorrhage.

    A 69-year-old woman with mucoepidermoid carcinoma (MEC) of the tongue base came under our observation complaining of repeated episodes of haemoptysis. Mucoepidermoid carcinoma of the tongue base gives rise to a rather vague and aspecific symptomatology. Early symptoms include foreign body sensation in the oral cavity, undefined paraesthesia, and sialorrhoea. With the progression of disease, dysphagia, otalgia, and painful swallowing are usually referred. We report a case of mucoepidermoid car...

  8. Decreased uptake of therapeutic doses of iodine-131 after 185-MBq iodine-131 diagnostic imaging for thyroid remnants in differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

    We performed a prospective random study to assess possible thyroid stunning by a 185-MBq iodine-131 dose used to diagnose thyroid remnants. Patients with differentiated thyroid carcinoma were included after total or near-total thyroidectomy. They were randomly assigned to two groups. In group 0 (G0, 32 patients), iodine-123 administration only was used to diagnose thyroid remnants and/or metastasis, so that no thyroid stunning by 131I would occur. In group 1 (G1, 19 patients), diagnostic imaging was performed with 123I and 185 MBq 131I. 123I imaging was less sensitive than 131I imaging in identifying thyroid remnants in both groups (94%). Thyroid uptake of 123I was measured in both groups (at 2 h) and was not significantly different between the groups. Patients with thyroid remnants who remained in the study (28/32 in G0, 17/19 in G1) were treated with 370 MBq 131I, 5 weeks after treatment (mean time, range 12-84 days). In 12/17 G1 patients thyroid uptake measurement was repeated immediately before treatment. Uptake was equal to 1.97%±0.71% and significantly lower (P131I decreases thyroid uptake for several weeks after administration and can impair immediate subsequent 131I therapy; (2) 123I is slightly less sensitive than 131I in identifying thyroid remnants; and (3) the need to scan for thyroid remnants remains to be confirmed, since only 2/51 patients enrolled in this study were not treated with 131I.

  9. Thyroid carcinoma in the atomic bomb survivors of Hiroshima and Nagasaki 1958 - 1976

    International Nuclear Information System (INIS)

    Relation between radiation dose and incidence rate of thyroid carcinoma in A-bomb survivors exposed with large doses was studied by analyzing 82 cases in total consisting of those reported by Parker et al. from 1956 to 1971 and additional 19 cases lately occurred until 1976. Among them, 40 cases were clinically evident cancer confirmed histologically from clinical findings, and 42 cases were silent cancer confirmed by autopsy findings. The incidence rate of thyroid carcinoma during these 18 years rose along with the increase of radiation dose, and especially, this trend is marked in women. More noticeable dose-response was observed in clinically evident cancer. In a dose-response curve, it was observed that the incidence rate tends to rise higher with an increase of doses. However, in terms of statistics, a significantly higher incidence rate than that of a control group of 0 rad was first observed in the group of 50 - 100 rad. As far as the annual changes of radiation-induced thyroid carcinoma are concerned, the group of over 100 rad still showed an increase of the incidence rate of thyroid carcinoma. By ages when patients were exposed to A-bomb, a group of those exposed under 30 years old showed an increase of the incidence rate since 1968 or 1969, while the group of those exposed at relatively higher ages recorded the high incidence rate already in 1958 and showed no remarkable increase afterwards. Also it was indicated that a noticeable influence given by A-bomb radiation appears after cancer age. By histological types, papillary type and papillary sclerosing type were often observed in clonically evident cancer and silent cancer, respectively. Papillary type was rather often seen in the group of over 100 rad. (Iwagami, H.)

    Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical resection was performed because the ultrasonogram showed diffuse microcalcifications, which suggested m...

  14. Surgical options in the management of well differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

    Goitre is a common every day problem but cancer of the thyroid is a comparatively rare disease. It constitutes only 1.3 % of all cancers seen at the Tata Memorial Hospital. The surgeon has a central role in the management of cancer of the thyroid. All other modalities of treatment, like radioiodine therapy follow his surgery and depend on the extent of surgery performed. It is therefore important that the surgeon has a clear cut policy of management. Although surgery is the prime mode of treatment, the extent of surgery has been a matter of debate. Additionally, what constitutes adequate surgical treatment itself is highly controversial. A policy for management based on the natural history, biological behaviour of the disease and the previous treatment methods is discussed

  15. Papillary thyroid carcinoma, dermoid cyst and polycystic ovary syndrome: a case report

    International Nuclear Information System (INIS)

    Full text: Total body scintigraphy after the I-131 treatment for thyroid carcinoma is a routine procedure in staging. For smaller tumors uptake outside the neck is seldomly seen, usually benign and without clinical significance. However, a conscientious analysis of there accumulations can be relevant. A 33 year-old female presented in December 1998 with a T2N1M0 papillary thyroid carcinoma. Thyroidectomy, neck dissection and 50 mCi 1-131 treated her. The post-therapy scan was negative except for a small spot in the neck (thyroidremnant: 3.0 %). In September 1999 150 mCi was administered and the scan afterwards showed a focus median in the neck (thyroid remnant: 0.3 %) and a persistent hotspot in the left lower quadrant of the abdomen (figure). The thyreoglobuline was 3.8 μg/l (unchanged to the first I-131 therapy) during maximal TSH Stimulation (174 mu/l). Transvaginal ultrasound revealed an enlarged left ovary which was laparoscopical removed and appeared to be a dermoid cyst with hair- and skincomponents, respiratory epithelia and bone. Only after staining on thyreoglobuline thyroid tissue was demonstrated; there were no signs of malignancy. Six months later a 10 mCi I-131 scintigraphy was negative; thyreoglobuline was < 0.5 μg/l and TSH 161 mg/l suggesting no thyroid tissue was present in the Body. Her medical history showed a polycystic ovary syndrome (PCOS). She received treatment for ovulation induction including clomiphene, HCG, FSH and LH. Her thyroid function was normal. After two miscarriages She gave birth to a daughter. Germ cells must been present since birth to form a dermoid cyst during life. In our patient, the dermoid cyst with benign thyroid cells was visualized only after the second I-131 therapy. We assume that the sensitivity of a scan after 50 mCi and 150 mCi I-131 is equal. Therefore, probably not the ovulation induction medication but the TSH stimulation for the I-131 therapy is the reason for the development of the dermoid cyst. That only

  17. Thyroid carcinoma in solitary hot thyroid lesions on Tc-99m sodium pertechnetate scans

    International Nuclear Information System (INIS)

    Sixteen patients with nonsuppressible solitary hot thyroid lesions (SHTL) identified on T3 suppression images using Tc-99m sodium pertechnetate were studied over a period of 5 years. Of the 16 patients, 7 (44%) had papillary adenocarcinoma (PAC) and 9 (56%) had follicular adenoma (FA), 2 were toxic and 7 nontoxic. The Tl-201 chloride thyroid scans were useful in locating SHTL and revealing extranodular thyroid tissue. The echography was sensitive to visualization of the nodule structures. However, there were no significant differences between the clinical findings, radionuclide images, and echograms between for PAC and FA. All patients with PAC were treated by partial thyroidectomy and there were neither regional nor distant metastasis in any of them. In conclusion, our study provided the following extremely interesting results: SHTL in the present series have a higher incidence of malignancy than previously reported autonomously functioning thyroid lesions (AFTL). Histological examinatinon is necessary for the diagnosis and management of SHTL and surgical treatment should be considered. (author)

    Asad Jehangir

    2015-02-01

    Full Text Available Background: Follicular thyroid cancer (FTC metastasizes most commonly to the lungs and non-cranial bones. Skull and skin are uncommon sites and usually manifest well after the diagnosis of primary malignancy. Metastasis to skull and skin as the presenting feature of FTC is infrequently reported in the literature. Case presentation: A 65-year-old Caucasian woman with a history of thyroid nodule presented with the complaint of rapidly growing skull nodules which had been present for 3 years but were stable previously. She denied any fevers, chills, history of trauma, or weight loss. She denied any history of smoking or head and neck irradiation. On physical examination, she had two non-tender gray cystic lesions – one on her left temporal region and the other on the right parietal region. Biopsy was consistent with metastatic FTC. Magnetic resonance imaging of the brain demonstrated 7.1×3.8 cm and 3.7×4.5 cm fairly homogeneous, enhancing, relatively well-defined masses centered in the posterior and left anterior lateral calvarium with intracranial and extracranial extensions but without any vasogenic edema or mass effect on the brain. Thyroid ultrasound showed numerous nodules in both lobes. The patient underwent a total thyroidectomy. Histopathological studies of the thyroid gland revealed a well-differentiated FTC in the left lobe. Then she underwent resection of the tumor in multiple stages. She did not have any recurrence of the FTC or metastases during the follow-up period and will be receiving radioactive iodine treatment. Conclusion: Bone and lung are the common sites of metastasis from FTC, but involvement of skull or skin is unusual, particularly as the presenting feature. Metastases from FTC should be in the differential of patients with new osteolytic hypervascular skull lesions or cutaneous lesions in head and neck area.

  19. Prognostic factors for differentiated thyroid carcinoma in young patients

    International Nuclear Information System (INIS)

    Standard therapy of differentiated thyroid cancer (DTC) comprises thyroid surgery, radioiodine treatment and L-thyroxine suppressive treatment. However, in the case of young patients the extent of surgery and the need for radioiodine treatment are questioned by some authors on the basis of the overall good prognosis in this group. The aim of the study was to perform a retrospective analysis of prognostic factors for differentiated thyroid cancer in patients in the first three decades of their life. The study included 274 patients who were younger than 28 years at the day of diagnosis of DTC and were observed for a mean time of 5 years. Uni- and multivariate analysis of prognostic factors for disease - free survival was performed with Cox's regression method. The actuarial survival rate was 100%, the 5 and 10-year actuarial disease free survival was 85% and 75%, respectively. In a multivariate analysis lymph node metastases, the extent of surgery and radioiodine therapy were estimated as statistically significant, independent prognostic factors for DTC relapse. Radical treatment of DTC more advanced than pT1NOMO should include total thyroidectomy and postoperative complementary radioiodine therapy. Such procedure is also justified in young patients, as it ensures a decrease of the risk of recurrence. (author)

    We aimed to evaluate the diagnostic utility of the novel immunohistochemical marker TROP-2 on thyroid specimens (226 tumours and 207 controls). Whole slide immunohistochemistry was performed and scored by automated digital image analysis. Non-neoplastic thyroid, follicular adenomas, follicular carcinomas, and medullary carcinomas were negative for TROP-2 immunostaining. The majority of papillary thyroid carcinoma (PTC) specimens (94/114, 82.5%) were positive for TROP-2; however, the pattern of staining differed significantly between the histopathological variants. All papillary microcarcinomas (mPTC), PTC classic variant (PTC cv), and tall cell variant (PTC tcv) were TROP-2 positive, with mainly diffuse staining. In contrast, less than half of the PTC follicular variant specimens were positive for TROP-2, with only focal immunoreactivity. TROP-2 could identify PTC cv with 98.1% sensitivity and 97.5% specificity. ROC curve analysis found that the presence of >10% of TROP-2 positive cells in a tumour supported a diagnosis of PTC. The study of intratumoural heterogeneity showed that low-volume cytological samples of PTC cv could be adequately assessed by TROP-2 immunostaining. The TROP-2 H-score (intensity multiplied by proportion) was significantly associated with PTC variant and capsular invasion in encapsulated PTC follicular variant (pdisease, stage) parameters were correlated with TROP-2 expression. In conclusion, TROP-2 membranous staining is a very sensitive and specific marker for PTC cv, PTC tcv, and mPTC, with high overall specificity for PTC. PMID:27311870

    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.

  4. Differentiation between healthy thyroid remnants and tumor tissue after radioiodine therapy in patients with differentiated thyroid carcinoma using in-vitro phosphorus-31 magnetic resonance spectroscopy

    International Nuclear Information System (INIS)

    Full text: In many tumors, tumor growth and spread is triggered by changes in cell membrane metabolism, which can lead to systemic alterations in levels of phospholipids. The aim of this study was to differentiate between healthy remnants of thyroid tissue and residual/recurrent tumor tissue or metastases in patients with thyroid carcinoma by measurement of plasma levels of various phospholipids. Phospholipid concentrations was measured by in-vitro phosphorus-31-magnetic resonance spectroscopy (31P-MRS) in blood samples from 30 patients with thyroid cancer, who had been rendered hypothyroid in preparation for diagnostic/therapeutic administration of iodine-131. All patients were already thyroidectomized. 131I-whole-body scintigraphy and measurements of thyroglobulin values in a 2-year-follow-up were used to distinguish between patients in remission, patients with only healthy thyroid remnants and patients with cancerous thyroid tissue and/or metastases. Significantly lower blood plasma levels of systemic sphingomyelin (0.33±0.06 vs. 0.46±0.03 (controls) mmol/l; p31P-MRS can be used to differentiate between the presence of tumor tissue, healthy remnants of thyroid tissue not requiring further treatment and remission in patients with thyroid cancer. In future, therefore, plasma 31P-MRS could be developed as an additional diagnostic tool for the follow-up of differentiated thyroid cancer. (author)

    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.

  6. Mutual regulation of TGF-β1, TβRII and ErbB receptors expression in human thyroid carcinomas

    International Nuclear Information System (INIS)

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

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

  9. Radioiodine therapy in management of thyroid carcinoma - A review of 138 patients

    International Nuclear Information System (INIS)

    Differentiated thyroid carcinomas are being treated by using a widely accepted protocol of surgery and radioiodine therapy followed by supplementation of thyroid hormones in the Nuclear Medicine Centre (NMC), Dhaka Medical College Hospital (DMCH) since 1990. In the present study 138 patients(Male-54, Female-84) with differentiated thyroid cancers received radioiodine therapy for ablation of residual thyroid tissue with a dose of 2.77-3.7 GBq (75-100 mCi), for lymph node metastases 5.55-6.5 GBq(150-175mCi), for lung metastases 5.55 GBq(150 mCi) and for bony metastases 7.4 GBq (200 mCi). Among 138 patients papillary carcinoma was observed in 94 cases (68%; Male-42, Female-52), follicular type was found in 30 cases (22%; Male-8, Female-22) and mixed type in 14 patients (10%, Male-4, Female-10). Single dose of 2.77-3.7 GBq(75-100 mCi) of radioiodine was received by all 138 patients. Among the unablated patients 62 received double doses totalling 9.25 GBq (250 mCi), 44 received three doses 12.95 GBq (350 mCi) and one patient received 8 doses 33.3 GBq (900 mCi). Out of 138 patients single dose ablated 76 cases and 62 remain unablated. Multiple doses ablated 28 patients and 34 still remain unablated and is under follow up. The success and failure in management of patients with differentiated thyroid cancer over 8 years period have been discussed here revealing a satisfactory outcome. (author)

  10. Toxoplasmic Lymphadenitis Mimicking a Metastatic Thyroid Carcinoma at 18F-FDG-PET/CT

    International Nuclear Information System (INIS)

    A 28-year-old woman underwent total thyroidectomy for a papillary thyroid carcinoma in the right thyroid lobe (pTx, pN1b). Subsequently a 131I-ablation (4.4 GBq) was performed. Four years later the patient presented increased thyroglobulin (Tg) serum levels (8.4 μg/l) during thyroxine treatment. Furthermore, enlarged hypoechoic and round-shaped bilateral cervical lymph nodes were detected at cervical ultrasonography (US). Based on laboratory and US findings suspicious for lymph nodal recurrence of thyroid carcinoma, the patient underwent an 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) to check for distant metastases (Fig. 1). The patient underwent a US-guided fine-needle aspiration cytology on an 18F-FDG-avid cervical lymph-node. The smears were hypercellulated and consisted of numerous small- to medium-sized lymphocytes, macrophages, dendritic cells and tingible body macrophages. The cytological diagnosis was consistent with that of reactive lymphadenitis. Serological test revealed elevated IgM and IgG anti-Toxoplasma antibodies with a very low IgG-avidity, indicating an acute toxoplasmosis. Serum Tg was then measured by using heterophilic antibody blocking tubes, as previously reported, and serum value dropped to 18F-FDG-PET/CT in oncological patients. Few reports have described toxoplasmic infection mimicking malignancy at 18F-FDG-PET/CT; these findings were found mainly in immunodepressive patients or with history of lymphoma. Conversely, we described here a case of toxoplasmosis inducing false-positive Tg measurement, neck US and 18F-FDG-PET/CT findings in a patient with papillary thyroid carcinoma

    Full Text Available OBJECTIVES AND INTRODUCTION: Medullary thyroid carcinoma, a neoplasia of intermediate prognosis and differentiation, does not always respond predictably to known treatments. This study aimed to correlate the clinical progression of surgically treated patients with clinical and pathological data. METHODS: A total of 53 patients were followed for 75 months (mean average in tertiary-care hospital. The clinical status of patients at the end of the study period was characterized to determine correlations with a range of disease aspects. A value of p < 0.05 was considered statistically significant. RESULTS: Twenty-two patients (41.5% were alive and disease-free at the end of the follow-up period; twenty-three patients (43.4% had persistent disease; and eight patients (15.1% had recurrent disease. Four patients (7.6% died from medullary thyroid carcinoma with clinical and/or imaging evidence of neoplasia. The following aspects demonstrated statistically significant correlations with the final medical condition: positive initial cervical examination (p = 0.002; neoplastic extensions to the thyroid capsule (p = 0.004 and adjacent tissues (p = 0.034; cervical lymph node metastases (p < 0.001; diameter of neoplasia (p = 0.018; TNM (tumor, node and metastasis Stage (p = 0.001 and evidence of distant and/or cervical diseases in the absence of a cure (p = 0.011. Through logistic regression, the presence of cervical lymph node metastases was considered an independent variable (p < 0.001. CONCLUSIONS: Clinical and pathological aspects of patients with surgically treated medullary thyroid carcinomas are predictors of disease progression. Specifically, even treated cervical lymph node metastases are significantly correlated with disease progression.

    Objective:To study the value of preoperative serum LC3 and MMPs combined with TSH detection in diagnosis of papillary thyroid carcinoma and provide reference for clinical diagnosis and treatment. Methods:A total of 80 cases of patients with papillary thyroid carcinoma treated in our hospital from March 2010 to March 2014 were analyzed, and serum TSH, MMP2/9, TIMP1/2 and LC3 levels of patients before operation were detected by ELISA. Healthy subjects and patients with benign neoplasm of thyroid during the same period were taken as control. Results:Serum TSH, MMP2, MMP9 and LC3 levels in patients with papillary thyroid carcinoma significantly increased, TIMP1 and TIMP2 levels significantly decreased, and compared with healthy subjects and patients with benign neoplasm of thyroid, there were significant statistical differences;at the same time, above parameters in serum were not related to gender, but closely related to age, clinical stage and diameter of tumor as well as lymph node. Conclusion:Preoperative detection of serum LC3 and MMPs combined with TSH levels has important reference significance in diagnosis of papillary thyroid carcinoma.

  13. Thyroid cancer

    International Nuclear Information System (INIS)

    The role of ionizing radiation in the introduction of thyroid carcinoma is discussed. In the treatment of thyroid cancer, radioiodine administration is of value as an ablation procedure, completing the thyroidectomy and as a method to irradiate selectively functioning thyroid carcinoma tissue that cannnot be removed surgically. Results of the clinical management of 155 patients with malignant thyroid tumours are presented. The ablation dose of iodine-131 can be decreased to 40 millicuries thus effectively reducing the patients whole body radiation dose

    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.

  15. Second malignancies following the treatment of differentiated thyroid carcinoma with radioiodine

    International Nuclear Information System (INIS)

    Full text: To see the incidence of second cancers in patients with well differentiated thyroid carcinoma after being treated with radioiodine. Medical records of 814 (417 males, 397 females) patients with differentiated thyroid cancer treated at Institute of Nuclear Medicine and Ultrasound, Dhaka were reviewed. The purpose was to investigate the incidence of second cancer in these patients after radioiodine therapy. The age range of the patient population treated with radioiodine was 9 to 69 years. Doses of radioiodine given were in the range of 30 to 100mCi for ablation and 150 to 250mCi for treatment of metastasis. The median follow-up period was 93.7± 15 months. Eleven (1.35 %) of the 814 patients developed a second malignancy. Two patients (0.25%) developed chronic myelogenous leukemia within a latency period of 5 years and after receiving a cumulative dose of 600- 670mCi. The over all incidence of second malignancy in the form of solid tumors was 1.10%. Of the nine patients with solid tumors, there were two patients with renal cell carcinoma, three patients with parotid gland tumor, one patient with pancreatic cancer, one with adenocarcinoma of the stomach, one with carcinoid tumor and one with small cell carcinoma of the lungs. The mean latency period for development of these tumors was 6.92 ± 3.934 years and the mean cumulative dose received by all these patients was 537.25±120.55 mCi. Follow-up of a fairly large cohort of patients treated with radioiodine showed a low incidence of second neoplasm. No relation was observed between the cumulative dose received and the development of a second malignancy. Thyroid carcinoma is a polygenic disease, which may be associated with other malignancies. Common environmental or genetic factors as well as long-term carcinogenic effects of radioiodine therapy should be considered. (author)

    Primary thyroid cancers including papillary, follicular, poorly differentiated, and anaplastic carcinomas show substantial differences in biological and clinical behaviors. Even in the same pathological type, there is wide variability in the clinical course of disease progression. The molecular carcinogenesis of thyroid cancer has advanced tremendously in the last decade. However, specific inhibition of oncogenic pathways did not provide a significant survival benefit in advanced progressive thyroid cancer that is resistant to radioactive iodine therapy. Accumulating evidence clearly shows that cellular energy metabolism, which is controlled by oncogenes and other tumor-related factors, is a critical factor determining the clinical phenotypes of cancer. However, the role and nature of energy metabolism in thyroid cancer remain unclear. In this article, we discuss the role of cellular energy metabolism, particularly mitochondrial energy metabolism, in thyroid cancer. Determining the molecular nature of metabolic remodeling in thyroid cancer may provide new biomarkers and therapeutic targets that may be useful in the management of refractory thyroid cancers.

    The therapeutic response and survival rates of 352 patients with differentiated thyroid carcinoma who had received radioactive iodine therapy since 1951 were studied. Of these patients, 72% had metastases to the cervical lymph nodes, lungs, bone, or other viscera. Of all patients, 70% showed complete remission, and 30% showed partial response or recurrence of disease or both. Patients with metastases before therapy had a higher incidence of recurrence than those who had localized thyroid disease (32.4% vs. 15.1%). Of these, 97 patients had recurrent disease. In 24 of these patients, the recurrent tumor failed to take iodine, indicating change in its iodine-concentrating characteristics. Of the 352 patients, 44 (12.5%) died of progressive thyroid carcinoma, and all were over 40 years of age at the time of initial diagnosis. Mean survival of patients with metastatic disease who were over 40 years of age at initial diagnosis was significantly lower than that of patients under 40 years of age (6.2 years vs. 11.5 years). Patients with recurrent metastases unresponsive to surgery or radioactive iodine therapy were treated with palliative radiotherapy or chemotherapy or both. They respond poorly and died within a few months.

    Full Text Available Background. Fine-needle aspiration (FNA can cause misdiagnosis of cytomorphological findings between parathyroid and thyroid lesions. Case Presentation. A 31-year-old man presented with a palpable neck mass on the right thyroid lobe. FNA cytology was reported as intrathyroidal lymphoid hyperplasia. After 5 years, repeated FNA was done on the enlarged nodule with result of Hürthle cell lesion. Prior to right lobectomy, laboratories revealed elevated serum calcium and parathyroid hormone (PTH. Careful history taking revealed chronic knee pain and ossifying fibroma at the maxilla. Ultrasonography showed a 2.8 cm mass inferior to right thyroid lobe. Pathology from en bloc resection was parathyroid carcinoma and immunohistochemical study revealed positivity for PTH. Genetic analysis found somatic mutation of CDC73 gene in exon1 (c.70delG which caused premature stop codon in amino acid 26 (p.Glu24Lysfs2*. The final diagnosis was hyperparathyroidism-jaw tumor syndrome. Conclusions. FNA cytology of parathyroid can mimic thyroid lesion. It is important to consider and correlate the entire information from clinical history, laboratory, imaging, and FNA.

    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.

    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

  2. Introduction of v-Ha-ras oncogene induces differentiation of cultured human medullary thyroid carcinoma cells

    International Nuclear Information System (INIS)

    Medullary thyroid carcinoma (MTC) is an endocrine tumor of the thyroid C cells that expresses high levels of the neuroendocrine peptide hormone calcitonin. During tumor progression in the host, there is an apparent loss of differentiation in MTC cells that involves a consistent decrease in calcitonin content of the tumor cells associated with decreased expression of the calcitonin gene and/or changes in a mRNA alternative-processing pattern away from that characteristic of the parent thyroid C cell. The authors now report that introduction of the viral Harvey ras (v-Ha-ras) oncogene into cultured human MTC cells can reverse such changes in gene expression and can induce endocrine differentiation of the tumor cells. The expression of v-Ha-ras is associated with decreased cellular proliferation and DNA synthesis. There is a marked increase in the number of cytoplasmic secretory granules that are a classic feature of differentiated thyroid C cells. v-Ha-ras expression induces increased expression of the calcitonin gene and the processing of the primary gene transcript is shifted to favor calcitonin mRNA rather than calcitonin-gene-related peptide (CGRP) mRNA production. These studies with cultured human MTC cells provide a model system to study the role of Ha-ras and related genes in neuroendocrine differentiation. The findings suggest an important approach for identifying genes in solid tumors whose altered expression may play a role in the impaired maturational capacity characteristic of cancer cells during tumor progression

In the second case, the diagnosis was more precocious and antineoplastic chemotherapy was used after the surgery. At the time of submission of this manuscript, this animal had survived for fourty months. Currently, there is a need to define the protocols of chemotherapy to avoid relapse and metastases, in order to increase the life expectancy in dogs with thyroid neoplasm.

  4. Chromosomal rearrangements and the pathogenesis of differentiated thyroid cancer

    Directory of Open Access Journals (Sweden)

    Stefan K.G. Grebe

    2011-12-01

    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.

  6. Synchronous papillary carcinoma thyroid with malignant struma ovarii: A management dilemma

    International Nuclear Information System (INIS)

    Struma ovarii (SO) is a rare form of ovarian tumor, which is defined by the presence of thyroid tissue comprising more than 50% of the overall tumor volume. The vast majority of the variants of SO are benign; however, malignant tumors have been reported in a small percentage of cases. An aggressive multimodality approach using ovarian cancer staging laparotomy, total thyroidectomy along with radioactive iodine-131 ablation, and thyroxin suppression therapy has been shown to safely treat malignant SO both its initial presentation as well as in the event of any subsequent recurrence with excellent efficacy and possibly better oncological outcomes. The rarity of the disease and the lack of evidence surrounding its management and prognosis continue to remain a challenge to the treating clinician. We present a unique case of malignant SO with an incidental synchronous association of follicular variant of papillary carcinoma of the cervical thyroid gland, this is possibly the second case reported in the English language literature

  7. Surgery for lymph node metastases of medullary thyroid carcinoma: A review.

    Science.gov (United States)

    Jin, Linda X; Moley, Jeffrey F

    2016-02-01

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

    Full Text Available Background: Medullary thyroid carcinoma (MTC is a tumor arising from the para follicular (C cells of the thyroid gland and can occur either sporadically or as part of an inherited syndrome. A proportion of these cases carry an autosomal dominant mutation in the RET (REarranged during Transfection proto-oncogene. Screening for these mutations in the affected patients and the carriers ′′at risk′′ which includes the first-degree relatives is of utmost importance for early detection and prompt treatment including prophylactic thyroidectomy in cases that harbor these mutations. Results: This report presents details of screening and subsequent follow-up of a large Indian family, where the index case was found to carry p.Cys634Ser mutation involving exon 11 of the RET gene. These data are of value considering the paucity of information within the region in context of screening large families affected by these mutations.

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

    Full Text Available Although very rare, medullary thyroid carcinoma (MTC is the most aggressive in differentiated thyroid malignancies. We report a 48-year-old male patient with the diagnosis of MTC, who was monitored for fifteen years and showed no serious adverse events due to long-term chemotherapy. Total thyroidectomy, neck dissection, retrosternal nodule excision and pericardiectomy were performed, and radiotherapy was applied to the neck area. Due to progressive metastatic disease cyclophosphamide, dacarbazine, and vincristine were administrated. He tolerated chemotherapy well, and no severe systemic side effects were detected. He died due to multi-organ failure after fifteen years of diagnosis. The only curative treatment is surgery in MTC, however; radiotherapy, chemotherapy, and embolization may be used for patients for whom surgery cannot be performed. Although success rates of systemic chemotherapy are low, it is a treatment option in the progressive metastatic disease.

    International Nuclear Information System (INIS)

    This study was designed to study the physiopathology of the tumoral uptake of pentetreotide-111 In in medullary thyroid carcinoma and to evaluate the benefit of factor analysis. Eleven patients with suspected medullary thyroid carcinoma or its recurrence were studied. For all ten patients with medullary thyroid carcinoma, factor analysis showed that the kinetics of tumoral uptake were identical. In three patients with local malignant infiltration static view did not show abnormal uptake. In all of them, factor analysis revealed a diffuse uptake in the cervical area with the same kinetics of uptake as in other tumors. For one patient whose final diagnosis was a paraganglioma, the tumor was shown on two different factor images with a vascular kinetic component and with a tumoral component. (authors)

    The interaction of programmed cell death-1 and its ligand is widely studied in cancer. Monoclonal antibodies blocking these molecules have had great success but little is known about them in thyroid cancer. We investigated the role of PD-L1 in thyroid cancer with respect to BRAF mutation and MAP kinase pathway activity and the effect of anti PD-L1 antibody therapy on tumor regression and intra-tumoral immune response alone or in combination with BRAF inhibitor (BRAFi). BRAFV600E cells showed significantly higher baseline expression of PD-L1 at mRNA and protein levels compared to BRAFWT cells. MEK inhibitor treatment resulted in a decrease of PD-L1 expression across all cell lines. BRAFi treatment decreased PD-L1 expression in BRAFV600E cells, but paradoxically increased its expression in BRAFWT cells. BRAFV600E mutated patients samples had a higher level of PD-L1 mRNA compared to BRAFWT (p=0.015). Immunocompetent mice (B6129SF1/J) implanted with syngeneic 3747 BRAFV600E/WT P53−/− murine tumor cells were randomized to control, PLX4720, anti PD-L1 antibody and their combination. In this model of aggressive thyroid cancer, control tumor volume reached 782.3±174.6mm3 at two weeks. The combination dramatically reduced tumor volume to 147.3±60.8, compared to PLX4720 (439.3±188.4 mm3, P=0.023) or PD-L1 antibody (716.7±62.1, P<0.001) alone. Immunohistochemistry analysis revealed intense CD8+ CTL infiltration and cytotoxicity and favorable CD8+:Treg ratio compared to each individual treatment. Our results show anti PD-L1 treatment potentiates the effect of BRAFi on tumor regression and intensifies anti tumor immune response in an immunocompetent model of ATC. Clinical trials of this therapeutic combination may be of benefit in patients with ATC. PMID:26943572

    organs, such as the narrow and gonads, of up to 78.4%.Possible benefits to the institution also include the use of less radioactive material and a reduction in radiation exposures to the staff during the manipulation and administration of the 131 I. To facilitate the calculations of the optimum therapeutic activity of 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 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.

    Thyroid nodules are the most frequent endocrine disorder and occur in approximately 30% of the German population. Thyroid nodular disease constitutes a very heterogeneous entity. A striking diversity of possible functional and morphological features of a thyroid tumour derived from the same thyroid ancestor cell, is a hallmark of thyroid tumorigenesis and is due to specific genetic alterations. Defects in known candidate genes can be found in up to 70% of differentiated thyroid carcinomas and determine the respective cancer phenotype. Papillary thyroid cancers (PTC) harbour BRAF (or much less frequently RAS) mutations in sporadically occurring tumours, while radiation-induced PTC display chromosomal rearrangements such as RET, TRK, APR9 / BRAF. These genetic events results in constitutive MAPKinase activation. Follicular thyroid cancers (FTC) harbour RAS mutations or PAX8/ PPAR{gamma} rearrangements, both of which, however have also been identified in follicular adenoma. In addition, recent studies show, that activation of PI3K/AKT signalling occurs with high frequency in follicular thyroid tumours. Undifferentiated (anaplastic) thyroid cancers (ATC) display genetic features of FTC or PTC, in addition to aberant activation of multiple tyrosinkinase pathways (overexpression or mutations in PI3K and MAPK pathways). This underscores the concept of a sequential evolution of ATC from differentiated thyroid cancer, a process widely conceived to be triggered by p53 inactivation. In contrast, the molecular pathogenesis of benign thyroid tumours, in particular cold thyroid nodules is less known, except for toxic thyroid nodules, which arise from constitutive activation of cAMP signalling, predominantly through TSHR mutations.

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

    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.

  1. Comparison of different 131I doses for thyroid remnant ablation in patients with differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

    Objective: To compare the ablation efficacy of different 131I doses for thyroid remnant in patients with DTC, and to analyze the factors related to the ablation efficacy. Methods: A total of 343 DTC patients without local or distant metastases post total or near-total thyroidectomy were enrolled into this study. The patients were divided into three groups according to the initial 131I ablation dose: group A included 101 patients with 1850 to 2220 MBq, group B included 103 patients with 2590 to 2960 MBq, group C included 139 patients with 3330 to 3700 MBq. The patients were followed up for 6 to 12 months after initial 131I ablation. Successful ablation was determined according to follow-up 131I whole body scan and TSH stimulated serum Tg levels (<10 μg/L). The χ2 test and logistic regression were performed. Results: The overall successful rate was 63% (215/343). The successful rates in groups A, B and C were 59% (60/101), 64% (66/103) and 64% (89/139), respectively, with no significant difference among three groups (χ2=0.657, P=0.720). Univariant analysis identified that gender (P=0.030), type of surgery (P<0.01), number of the operations (P=0.004), pre-treatment TSH (P=0.019) and pre-treatment Tg (P<0.01) levels were related to the successful ablation rate. Logistic regression identified type of surgery (P<0.01) and pre-treatment Tg (P<0.01) level as the independent predictors for successful ablation. Conclusions: Low dose 131I for thyroid remnant ablation is almost similar to higher dose for DTC patients. However, the type of surgery and pre-treatment TSH stimulated Tg level affect the success rate of 131I ablation. (authors)

  3. Thyroid size change by CT monitoring after sorafenib or sunitinib treatment in patients with renal cell carcinoma: Comparison with thyroid function

    International Nuclear Information System (INIS)

    Objective: Hypothyroidism is a common complication in patients receiving tyrosine kinase inhibitors. We evaluated the relationship between thyroid size evident on CT and thyroid function in patients with advanced renal cell carcinoma (RCC) receiving tyrosine kinase inhibitors. Materials and methods: Forty-two patients with metastatic RCC receiving tyrosine kinase inhibitors (sorafenib n = 25; sunitinib n = 17) and, followed-up for ≥12 months were eligible. Patients who had ever shown an elevated thyroid-stimulating hormone (TSH) level of >10 mU/l were defined as having “hypothyroidism”. CT scans were performed before, and 3, 6, 9, and 12 months after the start of treatment. The area of the thyroid in the maximum section at each examination was measured and compared with that before treatment. Using repeated-measures ANOVA, differences in thyroid size were compared over time between patients with and without “hypothyroidism”, in relation to the type of drug employed. Results: Twenty-one patients (sorafenib 9, sunitinib 12) developed “hypothyroidism” 95 ± 88 days (range 12–315 days) after the start of treatment. In such patients, the thyroid was reduced in size to 89 ± 16% after 3 months, 81 ± 21% after 6 months, 71 ± 21% after 9 months and 68 ± 21% after 12 months, whereas the patients without “hypothyroidism” maintained a thyroid size of 90 ± 12% even after 12 months (p = 0.0030). Among the patients with “hypothyroidism”, those treated with sunitinib tended to show greater thyroid size reduction than those with sorafenib (59 ± 23% vs. 79 ± 13%, after 12 months). Conclusion: Tyrosine kinase inhibitors cause an apparent thyroid size reduction in patients with “hypothyroidism”

    A Schmorl's node is a common incidental finding encountered during radiologic imaging. Despite the vertebral body being a common site of metastatic disease, a lytic lesion adjacent to an endplate with typical imaging features can often confidently be called a Schmorl's node. This is a case report of a patient with a single well-defined FDG-avid papillary thyroid carcinoma metastasis to the spine that had imaging findings characteristic of a Schmorl's node on CT and MRI. This case is important to consider as it demonstrates that the imaging characteristics of metastatic disease and Schmorl's nodes can overlap.

    Full Text Available Primary squamous cell carcinoma of the thyroid is an extremely rare neoplasm with aggressive behavior. Until date, only around 60 cases have been reported in the literature. Primary treatment of the patient is radical surgery. With optimum treatment survival is not more than 6 months in this aggressive malignancy. However in our patient surgery it was not possible because of unresectability of the mass due to encroachment of major vessels. Hence, we have delivered radiotherapy alone, with which effective palliation could be achieved and patient is leading a good quality-of-life for last 1 year.

  11. Impaired DNA repair as assessed by the ''comet'' assay in patients developing thyroid carcinoma after radiotherapy

    International Nuclear Information System (INIS)

    A defective cellular response to DNA lesions induced be genotoxic agents may be associated to an increased cancer proneness. This has been clearly identified in some rare but extensively studied genetic diseases such as xeroderma pigmentosum (XP), ataxia telangiectasia (AT) and Fanconi anemia (FA). In practical oncology, most patients receive genotoxic therapeutic agents and the presence of so far unidentified sensitive genotypes could account for an increased susceptibility to cancer in a subgroup of exposed patients. The thyroid gland of children is especially sensitive to the carcinogenic effect of ionizing radiation. Evidence for risk is reported even at doses as low as 0.1 Gy, and the excess relative risk to develop a thyroid tumor following a radiation dose of 1 Gy in childhood is of 7.7 [l]. In order to determine if a defect in repair of DNA strand breaks could be involved, as an early step, in the development of secondary thyroid tumors after radiotherapy, we examined, using the alkaline single cell gel electrophoresis assay (SCGE or 'comet'), the response to in vitro γ-rays exposure of lymphocytes of a small group of patients who developed thyroid carcinoma after radiotherapy for a primary tumor. Because of its practical advantages, the alkaline comet assay offers the opportunity to question the role of DNA strand beaks rejoining capacity of the individual in the radiation induced carcinogenesis of thyroid tumors. This preliminary study of a small group of patients with therapeutic irradiation at childhood for a primary tumor indicates that, at the time of blood sampling, lymphocytes of some of these patients demonstrated reduced rejoining capacity. These results suggest that the comet assay might help to distinguish a subgroup of individuals at risk for radiation induced genomic instability and encourage further investigation. (authors)

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

  13. Potential of radioiodine therapy in the treatment of medullary thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: The effect of I-131 ablation therapy as an adjunct to surgery in the management of patients with medullary thyroid carcinoma (MTC) was studied in our institute. The theme of the study was that among post surgical management of MTC, radioiodine therapy may be considered as a promising adjunct to surgery. No other therapeutic alternative is found to be practical and in recent years there have been several somewhat encouraging reports of treatment of medullary carcinoma of the thyroid with I-131. We have had the opportunity to address this notion on our group of patients. The patients underwent total thyroidectomy and hemithyroidectomy as a procedure. During the year 1988- 2007, 402 Ca thyroid patients were treated with radioiodine in our department of nuclear medicine for ablation of post thyroidectomy remnant tissue. Of these, 14 (3.48%) patients had been suffering from MTC; male to female ratio was 1:1 with mean age of 37.7 yrs ranging from 24-53 yrs. Among these 14 patients, 11(77%) had total thyroidectomy and 3 (23%) hemithyroidectomy. Hemithyroidectomy cases were accepted for ablation, where patients refused second surgery or the cases were inoperable according to the opinion of the concerned Surgeon. They were treated with a mean dose of 89 mCi of I-131 ranging from 75-100 mCi. The post therapy follow up was done at 6 months and 12 months following I- 131 treatments and imaged at 72 hrs. The following parameters were used as success indicator- i) Observation of reduced plasma calcitonin level; ii) Absence of any focal visible uptake in the anterior neck area of thyroid bed. iii) No physical complaints. High success rate and a set of good agreements were obtained from the study. Ablation was achieved in 11 (78%) cases out of 14 patients who were given RIT after thyroidectomy. Reduced/normal plasma calcitonin level was observed in almost in all patients. Out of 14 patients, only 1 patient died of his disease who had extensive metastasis during the

    A greater percentage of thyroid cancers can be detected by ultrasound-guided fine-needle aspiration biopsy (UG-FNAB) than by ordinary FNAB. A group of 678 patients were selected sequentially as having been diagnosed with benign nodules by the conventional FNAB method. We reexamined these patients by UG-FNAB and investigated the types of thyroid cancer that were missed by the conventional FNAB. Of the 678 patients diagnosed with benign nodules (using conventional FNAB), 571 (84.2%) demonstrated the same diagnosis when UG-FNAB was used. The remaining 107 patients (15.8%) studied were suspected of having a malignancy after UG-FNAB had been performed. Surgical specimen histology proved thyroid cancer in 99 of the 107 patients: 93 had papillary carcinoma, 4 had follicular carcinoma, 1 had medullary carcinoma and 1 had anaplastic carcinoma. Two drawbacks were noted when conventional FNAB was used: (1) cancer lesions difficult to palpate (n = 55) (e.g., small cancers with or without benign lesions or cancers associated with Hashimoto's thyroiditis or Graves' disease); and (2) palpable cancers with insufficient cell material for analysis (n = 44) (e.g., cystic carcinoma and cancers with calcified lesions. UG-FNAB is a powerful technique for detecting microcancers, cystic carcinomas, cancers associated with benign nodules, Hashimoto's thyroiditis, or coarse calcifications. PMID:8678961

    Full Text Available Background. The Warthin-like variant of papillary thyroid (WLPTC is a rare subtype of papillary thyroid carcinoma (PTC resembling Warthin tumors of the salivary glands. Due to its rarity, the clinicopathologic and molecular features of WLPTC remain unclear. Methods. Of the 2,139 patients who underwent surgical treatment for PTC from 2012 to 2013, 40 patients with WLPTC were identified and compared to 200 consecutive patients with classic PTC. BRAF mutation was tested with pyrosequencing. Results. There were no significant differences in age, predilection for women, multifocality, extrathyroidal extension, or lymph node metastasis between WLPTC and classic PTC. However, WLPTCs were more commonly associated with Hashimoto’s thyroiditis than classic PTCs (93% versus 36%, resp., P < 0.001 and showed significantly lower rate of BRAF mutation when compared to classic PTCs (65% versus 84%, resp., P = 0.007. In classic PTC, the frequency of BRAF mutations was negatively correlated with coexisting Hashimoto’s thyroiditis. When we compared WLPTC and classic PTC in the patients with coexisting Hashimoto’s thyroiditis, there were no significant differences in clinicopathologic characteristics or the BRAF mutational rate between the two groups. Conclusions. Patients with WLPTC have similar demographic, clinical, pathologic, and molecular characteristics to those with classic PTC coexisting with Hashimoto’s thyroiditis.

    Full Text Available Sarcoidosis is a systemic granulomatous disease of unknown etiology. In most cases, mediastinal lymph nodes and lung parenchyma are involved. In addition, the eyes, skin, abdominal organs, central nervous system or the joints might be involved during the course of the disease. Sarcoidosis has been found to be related with other autoimmune diseases such as thyroiditis. In this report, we present the case of a patient in whom hyperthroidism was found and Graves’ disease and papillary thyroid carcinoma were diagnosed while being investigated with a preliminary diagnosis of sarcoidosis. A 50-year-old male patient was admitted to our chest diseases clinic with the complaints of cough with colorless sputum, joint pain, weakness, weight loss (36 kgs, palpitations, tremor of the hands and pain in the right eye. Mediastinal lympadenopathy was detected on CT scan. Laboratory tests demonstrated hypercalcemia and low levels of parathyroid hormone (PTH. Eye examination revealed uveitis. Bronchoscopy was planned to confirm the diagnosis of sarcoidosis. Thyroid function test was performed and the patient turned out to have hyperthyroidism with high free T4 and low TSH levels. TSH receptor antibody titer was 71 U/L (0- 14 U/L. Ultrasonographic examination demonstrated enlarged thyroid gland and heterogeneous parenchyma with increased blood flow pattern. 4- and 24-hour radioiodine uptakes were 30% and 60%, respectively and scintigraphy findings were compatible with diffuse toxic goiter. On Hertel exophthalmometer, the measurements of the right and left eye were 23 and 24 mm, respectively. The diagnosis of Graves’ disease was made and thionamide therapy was started. Since active ophthalmopathy was present and the patient did not want to receive medical therapy for a long time, surgery was the best option for definitive therapy. The patient was prepared for the surgery with lugol solution (3x10 drops daily and after eutyroidism was achieved, bilateral total

    Carcinoma showing thymic-like elements (CASTLE) is a rare tumor affecting thyroid and neck soft tissues, which has to be distinguished from squamous cell and anaplastic thyroid carcinoma, because it has a better prognosis. We report a new case of CASTLE which occurred in a patient submitted to total thyroidectomy with central neck dissection. The tumor stained positively for CD5, which seems to be the most useful marker in the differential diagnosis. By the analysis of the 18 cases reported in literature, total thyroidectomy with selective modified neck dissection should be the treatment of choice and radiotherapy should be considered for patients with positive nodal status.

    Se presenta una paciente con tumor palpable ubicado en línea media de la región anterior del cuello, encima del hueso hioides, diagnosticado inicialmente como quiste del conducto tirogloso. Se realizó estudio preliminar, tanto clínico, como radiológico y citológico de la lesión. Mediante cirugía por técnica convencional, se extrajo el tumor. La biopsia por parafina definió la existencia de tiroides con carcinoma papilar. Añadido a dicha condición, la paciente presentaba glándula tiroidea en ubicación normal. Se considera un caso curioso, donde se mezclan los conceptos de duplicidad tiroidea y tiroides ectópico, con la presencia en este último de un carcinoma papilar.

    We present the case of a patient with a palpable tumor located in midline of the anterior neck above the hyoid bone, initially diagnosed as a thyroglossal duct cyst. Preliminary study of the lesion was conducted, both clinically and radiologically and cytologically. The tumor was removed through surgery by conventional technique. The paraffin biopsy defined the existence of thyroid papillary carcinoma. Despite this condition, the patient had thyroid gland in normal location. It is considered to be a curious case, combining the concepts of thyroid duplication and ectopic thyroid, with the presence, in this last one, of papillary carcinoma.

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

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

    Full Text Available Aim. Enlarged cervical lymph nodes (LNs in patients with thyroid cancer are usually assessed by fine-needle aspiration cytology (FNAC. Thyroglobulin (Tg is frequently elevated in malignant FNAC needle wash specimens (FNAC-Tg. The objectives of the study were to (1 determine an appropriate diagnostic cut-off for FNAC-Tg levels (2 compare FNAC and FNAC-Tg results in a group of 108 patients affected by differentiated thyroid carcinoma (DTC. 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.

    Full Text Available We are describing a 19-year-old white woman who presented with two synchronous primary cancers, namely glioblastoma multiforme and papillary thyroid cancer. The patient was admitted with dizziness, headache, and vomiting. CT head revealed acute intraparenchymal hematoma in the right cingulate gyrus and the splenium of the corpus callosum. Carotid and cerebral angiogram were unremarkable. MRI of the brain demonstrated a non-enhancing and non-hemorrhagic component of the lesion along the lateral margin of the hemorrhage just medial to the atrium of the right lateral ventricle that was suspicious for a tumor or metastasis. Brain biopsy confirmed it as glioblastoma mutiforme. CT chest was done to rule out primary cancer that revealed a 11 mm hypodense lesion in the left lobe of the thyroid and ultrasound-guided fine-needle aspiration biopsy confirmed it as papillary thyroid carcinoma. We should evaluate for multiple primary malignancies in young patients who are found to have primary index cancer.

    To compare the diagnostic efficacy of high-resolution sonography (HRS) and multidetector computed tomography (MDCT) in determining the presence of extraglandular invasion of thyroid papillary cancer and to define ultrasound (US) features of perithyroidal invasion that correlate with histopathological findings. We prospectively evaluated extracapsular invasion in 177 thyroid cancer patients using both HRS and MDCT. Receiver operating characteristics (ROC) were assessed with a four-point confidence scale (0 = no extracapsular invasion:1 = possible invasion:2 = probable invasion:3 = definite invasion) by two reviewers for each imaging modality. Sensitivity, specificity, and accuracy were analyzed for each modality, along with interobserver variability. MDCT had a mean area under the ROC curve larger than that of HRS (HRS = 0.733, MDCT = 0.807, p < 0.05). HRS and MDCT were significantly different with regard to diagnostic sensitivity, specificity, and accuracy for extrathyroidal extension (p < 0.05: HRS = 75.7%, 66.1%, and 69.8%, respectively: MDCT = 86.7%,69.7%, and 76%, respectively). Interobserver reliability was greater for MDCT than for HRS (kappa value, 0.861 versus 0.429). The cutoff value used in HRS for estimating the status of perithyroidal invasion was 2. Conclusion: HRS may be useful for preoperative investigation of thyroid papillary carcinoma extension, but it was inferior to MDCT because of lower diagnostic accuracy and lower interobserver reliability

  6. Treatment of patients with Huerthle cell thyroid carcinoma using [Lu-177-DOTAO, Tyr3]octreotate

    International Nuclear Information System (INIS)

    Full text of publication follows. Aim: Huerthle cell thyroid carcinoma (HCTC) is a variant of follicular thyroid carcinoma. Although radioiodine (I-131) is given for ablation of the thyroid remnant to enable serum thyroglobulin levels for follow-up, it is rarely used for the treatment of residual or metastatic disease, related to the Huerthle cell tumour's poor capacity of taking up radioiodine. Since thyroid tumour cells express somatostatin receptors, peptide receptor radionuclide therapy using radiopharmaceuticals such as [Lu-177-DOTA0,Tyr3]octreotate (Lu-177-octreotate) has been proposed as a potential treatment option. Materials and Methods: 15 patients with pathology proven HCTC treated with Lu-177-octreotate between January 2000 and April 2012 were studied. CT or MRI scans were analysed using SWOG criteria for response outcome. Thyroglobulin levels were analysed and a decrease of more than 50% was considered as a significant biochemical response. All patients had received radioiodine to ablate the thyroid remnant. Six patients received an additional treatment dose of I-131 (total cumulative dose range: 0.7 to 14.8 GBq I-131). Results: Acute side effects such as nausea, vomiting, pain, and hair loss were present during 22%, 2%, 8% and 27% of all administrations respectively. WHO grade 3 bone marrow toxicity for both platelets and leukocytes was present in 2% of all treatment cycles. No long-term side effects such as myelodysplasia or kidney failure were found during a median follow-up of 25 months (range 2-119 months). Twelve patients received the intended cumulative dose (22.2-29.6 GBq) of Lu-177-octreotate whereas 3 did not, due to persisting thrombocytopenia, concomitant cardiac atrial fibrillation, or to the diagnosis of rectal adenocarcinoma as a second primary tumour. In 11 out of the 12 remaining patients sufficient follow-up data were available for evaluation. Four (36%) patients had a partial response (PR) at 3 months after the last treatment

    A 28-year-old woman underwent total thyroidectomy for a papillary thyroid carcinoma in the right thyroid lobe (pTx, pN1b). Subsequently a {sup 131}I-ablation (4.4 GBq) was performed. Four years later the patient presented increased thyroglobulin (Tg) serum levels (8.4 μg/l) during thyroxine treatment. Furthermore, enlarged hypoechoic and round-shaped bilateral cervical lymph nodes were detected at cervical ultrasonography (US). Based on laboratory and US findings suspicious for lymph nodal recurrence of thyroid carcinoma, the patient underwent an {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG-PET/CT) to check for distant metastases (Fig. 1). The patient underwent a US-guided fine-needle aspiration cytology on an {sup 18}F-FDG-avid cervical lymph-node. The smears were hypercellulated and consisted of numerous small- to medium-sized lymphocytes, macrophages, dendritic cells and tingible body macrophages. The cytological diagnosis was consistent with that of reactive lymphadenitis. Serological test revealed elevated IgM and IgG anti-Toxoplasma antibodies with a very low IgG-avidity, indicating an acute toxoplasmosis. Serum Tg was then measured by using heterophilic antibody blocking tubes, as previously reported, and serum value dropped to <0.2 μg/l. It is well known that antibody interference may falsely increase serum Tg; in particular, increased anti-Toxoplasma antibodies likely interfered to the Tg measurement in our case. Additionally, activated granulocytes and macrophages may display significantly increased glucose consumption, giving false-positive results at {sup 18}F-FDG-PET/CT in oncological patients. Few reports have described toxoplasmic infection mimicking malignancy at {sup 18}F-FDG-PET/CT; these findings were found mainly in immunodepressive patients or with history of lymphoma. Conversely, we described here a case of toxoplasmosis inducing false-positive Tg measurement, neck US and {sup 18}F

  8. Assessment of female fertility and carconogenesis after iodine-131 therapy for differentiated thyroid carcinoma

    International Nuclear Information System (INIS)

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

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

    A 39-year-old female patient who had undergone a total thyroidectomy for a papillary thyroid carcinoma underwent a whole body scan with I-131. The I-131 scan was performed 72 hours after administering 185 MBq (5 mGi) of an I-131 solution. The anterior image of head, neck, and upper chest showed multiple areas of increased uptake in the mediastinal area considering of functional metastasis. However, radioactivity was not evident in the image taken after removing her clothes and muffler. The image obtained after placing the muffler on the pallet showed that the radioactivity was still present. It is well known that artifacts on an I-131 scan can be produced by styling hair sputum, drooling during sleep, chewing gum, and paper or a cloth handkerchief that is contaminated with the radioactive iodine from either perspiration or saliva. This activity might be mistaken for a functional metastasis. Therefore, it is essential that an image be obtained after removing the patient's clothes. In this study, artifacts due to a contaminated muffler on the I-131 scan were found. These mimicked a functional metastasis of the mediastinal area in a patient with a papillary thyroid carcinoma.

    Full Text Available Background. The cerebellum as initial site of distant metastasis from differentiated thyroid carcinoma (DTC including papillary (PTC and follicular thyroid carcinoma (FTC is rare manifestation. Case Presentations. Herein, we present three cases of cerebellar metastasis (CBM of PTC. Mean age of patients was 67 years (range: 64–72, and mean duration between initial diagnosis and CBM was 49.6 months (range: 37–61. Frequent location was left cerebellar hemisphere and was associated with hydrocephalus. All patients underwent suboccipital craniectomy, and in two patients postoperative intensity modulated radiation therapy (IMRT was given to deliver 5000 cGy in 25 fractions to residual lesions. Patient without postoperative IMRT had cerebellar recurrence along with lung and bone metastasis after 38 months. However, two patients were found alive and free of disease at the time of last follow-up. Conclusion. CBM from PTC is a rare clinical entity and is often associated with hydrocephalus. Histopathological diagnosis is important to initiate effective treatment, which relies on multidisciplinary approach to prolong the disease-free and overall survival rates.

    Full Text Available Background: Despite well-defined cytology features of papillary thyroid carcinoma (PTC in fine needle aspiration (FNA, diagnostic difficulties do exist while making decision in respect to papillary thyroid carcinoma (PTC cases. Aims: The aim of this study is to clarify diagnostic significance of various cytology features of PTC and to identify possible diagnostic pitfalls. Materials and Methods: FNA cytology (FNAC features and clinical findings of 17 PTC cases diagnosed on histology were retrieved. A retrospective review of these cases was performed. Results: The frequency and number of papillary formations, intranuclear cytoplasmic inclusions (INCI, and nuclear grooves (NG was more in PTC cases as compared to suggestive/suspicious of (S/O and rule out (R/O PTC cases. Cyst macrophages forming clusters were seen in six cases. Multinucleated giant cells (MGC were seen in seven cases. Large MGC with dense cytoplasm and more nuclei were seen in four PTC and one S/O PTC cases. Conclusion: FNAC features of PTC in FNA smears are neither constant nor specific. All the cytology features of PTC should be reported in proper context which allows endocrine specialist to treat and urgent histological verification.

  14. Guidelines on radioiodine therapy for differentiated thyroid carcinoma. Impact on clinical practice

    International Nuclear Information System (INIS)

    Aim: For the examination of the impact on clinical practice of the guidelines for differentiated thyroid carcinoma (DTC), treatment data from the ongoing multicenter study differentiated thyroid carcinoma (MSDS) were analyzed. Patients, methods: patients were randomized to adjuvant external beam radiotherapy (RTx) or no RTx in addition to standard therapy in TNM stages pT4 pNO/1/x MO/x (UICC, 5th ed. 1997). All patients were to receive the same treatment regimen consisting of thyroidectomy, ablative radioiodine therapy (RIT), and a diagnostic 131I whole-body scintigraphy (WBS) 3-4 months after RIT. Results: Of 339 eligible patients enrolled between January 2000 and March 2004, 273 could be analyzed. Guideline recommendations by the German Society for Nuclear Medicine from 1999 and 1992 were complied with within 28% and 82% with regard to the interval between surgery and RIT (4 vs. 4-6 weeks), in 33% and 84% with regard to 131I activity for RIT (1-3 vs. 1-4 GBq; ±10%), and in 16% and 60% with regard to 131I activity for WBS (100-300 vs. 100-400 MBq; ±10%). Conclusions: the 1999 guideline revision appears to have had little impact on clinical practice. Further follow-up will reveal if guideline compliance had an effect on outcomes. (orig.)

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

    Thyroid cancer is the most common endocrine malignancy and accounts for nearly 1% of all of human cancer. Thyroid cancer has four main histological types: papillary, follicular, medullary, and anaplastic. Papillary, follicular, and anaplastic thyroid carcinomas are derived from follicular thyroid cells, whereas medullary thyroid carcinoma (MTC) originates from the neural crest parafollicular cells or C-cells of the thyroid gland. MTC represents a neuroendocrine tumor and differs considerably from differentiated thyroid carcinoma. MTC is one of the aggressive types of thyroid cancer, which represents 3-10% of all thyroid cancers. It occurs in hereditary (25%) and sporadic (75%) forms. The hereditary form of MTC has an autosomal dominant mode of inheritance. According to the present classification, hereditary MTC is classified as a multiple endocrine neoplasi type 2 A & B (MEN2A & MEN2B) and familial MTC (FMTC). The RET proto-oncogene is located on chromosome 10q11.21. It is composed of 21 exons and encodes a transmembrane receptor tyrosine kinase. RET regulates a complex network of signal transduction pathways during development, survival, proliferation, differentiation, and migration of the enteric nervous system progenitor cells. Gain of function mutations in RET have been well demonstrated in MTC development. Variants of MTC result from different RET mutations, and they have a good genotype-phenotype correlation. Various MTC related mutations have been reported in different exons of the RET gene. We proposed that RET genetic mutations may be different in distinct populations. Therefore, the aim of this study was to find a geographical pattern of RET mutations in different populations. PMID:26678667

    Full Text Available Upper extremity deep vein thrombosis (UEDVT is a life threatening rare condition. Among the patients with UEDVT, internal jugular vein is accepted as uncommon thrombosis. Since internal jugular vein thrombosis (IJVT is mostly underdiagnosed, a great attention is needed to diagnose the disease. A 75-year-old woman with history of dyspnea on exertion (DOE, weight loss and anorexia with the stable vital sign and right-sided cervical adenopathy with suspected thyroid nodule was admitted. One day after admission, sudden dyspnea was occurring with unstable vital sign and hypotension. Chest X-ray showed a bilateral pleural effusion. Pleural tap was exudative, CT scan showed bilateral pulmonary emboli. CT scan of the neck showed right-sided cervical adenopathy, heterogeneous thyroid and internal jugular vein thrombosis concomitant with superior thyroid vein thrombosis. The patient was treated with thrombolytic agent and enoxaparin followed by warfarin. Thyroid FNA revealed papillary thyroid carcinoma that followed by total thyroidectomy, histopathological examination verified papillary thyroid carcinoma. Although lower extremity DVT is the main cause of pulmonary emboli, but IJVT may be proceed by pulmonary embolism. Due to fatal outcome of pulmonary emboli in IJVT, color duplex sonography, is recommended in documented tumors or suspected history of malignancy.
