    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.

    Normally, differentiated thyroid carcinoma(DTC) is a disease of good prognosis, but about 30% of the tumors are dedifferentiate, which are inaccessible to standard therapeutic procedures such as 'operation, 131 I therapy and thyroid hormone'. Both internal and abroad experts are researching a new therapy of dedifferentiated thyroid carcinoma--gene therapy. Many of them utilize methods of it, but follow different strategies: (1) transduction of the thyroid sodium/iodide transporter gene to make tissues that do not accumulate iodide treatable by 131 I therapy; (2) strengthening of the anti-tumor immune response; (3) suicide gene therapy; (4) depression the generation of tumor cells; (5) gene therapy of anti- vascularization.

    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.

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

    The medical records of eight dogs with histopathologically confirmed infiltrative thyroid carcinoma treated with external beam radiation were reviewed and a retrospective analysis of survival and local tumor control were performed. The dogs received a definitive radiotherapy protocol of 46.8-48 Gray. All dogs had a reduction in tumor size to a clinically undetectable level on follow up examinations. Kaplan-Meier analysis indicated a median survival time of 24.5 months. Pulmonary metastasis was detected in three dogs and one of these dogs had concurrent bone metastasis. One dog had bone metastasis alone. Two dogs were alive at the censor. This study suggests that fractionated, definitive radiation therapy using multiple, moderate doses of radiation is an effective treatment for local control of invasive thyroid carcinoma in dogs.

    In this document the case of a 66-year old woman is presented, with record of multi nodular goiter of 5 year of evolution, which is derived to scan ultrasound office to make a puncture-aspiration with thin needle because of the growth of nodular thyroid injuries. The ultrasound scan examination made before the puncture determine multiple dominant nodules of hyperplasia aspect between 15 and 25 mm of diameter and a small nodule of 6 mm suspected proliferate process. Despite its size, it was decided to include small nodule in injuries to a biopsy. The cytological study reveals nodular hyperplasia with carcinoma in the small nodule of 6 mm. A thyroidectomy is practiced on the patient. The deferred histological study of the thyroid gland confirms the finding of multi-nodular goiter with a small focus of papillar carcinoma. The ganglions examined were negative in the deferred examination [es

    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

    Brain metastases are rare in well-differentiated thyroid carcinoma but when present they can lead to the patient's death. Iodine-131 therapy for intracerebral thyroid carcinoma metastases causes radiation-induced acute cerebral edema that can lead to CNS complications and even death. We present a case in which a patient with intracerebral 131 I uptake developed seizures, slurred speech, and muscle weakness 12 hr following 131 I therapy. The patient's CT scan, post-therapy, confirmed an intracranial metastasis with a significant amount of surrounding edema. Radiotherapists, when using external beam radiation to treat intracerebral metastases, commonly place these patients on steroids, glycerol, or mannitol prior to instituting therapy, to prevent complications from radiation-induced cerebral edema. This technique could be applied to 131 I therapy of intracranial thyroid carcinoma metastases as well

    Full Text Available Medullary thyroid cancer (MTC is a rare neuroendocrine neoplasm that accounts for approximately 5% of all thyroid malignancies. The natural history of MTC is characterized by early lymph node and distant metastases, making complete surgical cure often impossible. Conventional chemotherapy and external beam radiation have been largely ineffective in altering the natural history of MTC. Therefore, there is a great need to develop novel therapeutic strategies to affect symptom control and reduce tumor burden in patients with widely disseminated disease. Here, we review several pathways which have been shown to be vital in MTC tumorigenesis and focus on the pathways of interest for which targeted drug therapies are currently being developed.

    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 {sup 131}I for patients less than 40 years old with occult papillary carcinoma without metastases. In case of metastases, however, {sup 131}I-therapy should be performed after total thyroidectomy. All follicular thyroid carcinomas, regardless of their size, are to be treated by total thyroidectomy and {sup 131}I-therapy. All patients receive TSH-suppressive levothyroxine therapy and undergo regular follow-up. (orig.).

  13. Thyroid Metastasis from Breast Carcinoma Accompanied by Papillary Thyroid Carcinoma

    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.

    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.

    Full text of publication follows. Introduction and aim: The aim of this paper is to present our experience of 131 I-MIBG therapy in the cases of aggressive form of medullary thyroid carcinoma (MTC) with local and distant metastases. MTC is an uncommon thyroid tumor, accounting from 3-5% of all thyroid malignancies, and arises from para-follicular C cells which produce calcitonin (CT). Prognosis of MTC is related to tumor extension at disease detection, but long-term survival in patients with disseminated MTC is still unsatisfactory. Methods: 4 female patients with metastatic MTC (63, 69 and 2 patients aged 73 years), which already underwent total thyroidectomy and selective neck dissection, received therapy with 100 mCi 131 I-MIBG in our Institute. Patients had widespread disease with neck recurrences (all 4 cases), liver and bone metastases (2 cases) and lung metastases (1 case). All those patients received the therapy twice, second one 3 months up to 1 year after the first cycle. After therapy, whole body scintigraphy was performed; tumor marker levels (CT, carcinoembryonic antigen - CEA, neuron specific enolase - NSE, chromogranin A - CgA and pro-gastrin releasing peptide - pro-GRP) were measured before and after therapy. Results: in one patient we observed a slight decrease in CT level after first MIBG therapy, in another one a slight decrease in CEA serum level, and no lung metastases were visible on whole body scan after second 131 I-MIBG therapy. In one of the two remaining cases there was a significant decrease in CT serum level only after neck dissection. In all cases the patients reported an improvement in subjective symptom reduction. Conclusion: 131 I-MIBG therapy could provide additional benefit to patients with MTC and could improve overall survival, but more patient should be treated in order to define the true potential of the therapy. The aim of this paper is to present our experience of 131 I-MIBG therapy in the cases of aggressive form of

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

    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.)

    Objective: To investigate the effects of some factors on recurrence after thyroidectomy of differentiated thyroid carcinoma (DTC). Methods: Three groups of DTC cases were studied during follow-up. All cases (n=298) of group 1 with diagnosed recurrence were analyzed statistically on age, gender, thyroid-operating mode and pathologic nature at first diagnosis. One hundred and eight cases of group 2 had received thyroid hormone-replaced therapy and 124 cases of group 3 had received thyroid hormone-replaced plus 131 I ablating therapy after thyroidectomy, and were analyzed and compared statistically by their therapeutic outcomes. Results: 1) From group 1, the ratios of male/female (1:1.5) and follicular/papillary (1:4) were higher than primary cases reported in literatures (1:2-3 and 1:8). The recurrence rates in the cases had primary lesion excised, unilateral thyroid or bilateral thyroid excised were decreased 47.3%, 34.2% and 18.5%, respectively. Recurrence mainly occurred at first 5 years after thyroidectomy (65.1%). 2) From group 2, recurrence rates were 4.63%, 8.33% and 12.04%, respectively at 1, 5 and 10 years, and 53.84% and 30.77%, respectively as local recurrence and distant metastases. From group 3, recurrence rates were 0.81%, 4.03% and 7.26%, respectively in 1, 5 and 10 years, and 5/9 and 2/9 as local recurrence and distant metastases, respectively. The statistic difference was significant (P 131 I ablating therapy after thyroidectomy may improve the prognosis of DTC (prolonging recurrence-free time, reducing recurrence rate and decreasing distant metastases).

    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)

    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, 5 th ed. 1997). All patients were to receive the same treatment regimen consisting of thyroidectomy, ablative radioiodine therapy (RIT), and a diagnostic 131 I 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 131 I activity for RIT (1-3 vs. 1-4 GBq; ±10%), and in 16% and 60% with regard to 131 I 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.)

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

    The WHO classification of thyroid tumours does not list the oncocytic carcinomas (Huerthle cell carcinoma) as a separate tumour entity. Whereas the diagnosis of oncocytomas is relatively easy because of their characteristic cytological appearance the typing as follicular or papillary carcinoma is often problematical for pathologists; more detailed directions for the typing of Huerthle cell carcinomas in the WHO classification would be useful. It is of clinical importance that most oncocytic carcinomas are obviously able to produce thyroglobulin but unable to take up radioiodine. No significant differences are seen in sex incidence and prognosis between oncocytic and non-oncocytic differentiated thyroid carcinomas. Some histomorphological findings such as aggressively infiltrating behaviour, invasion of blood-/lymphatic vessels, lack of papillary structures, and high mitotic activity seem to be signs of bad prognoses. For therapy of oncocytic carcinomas total thyroidectomy is recommended without subsequent radioiodine treatment but with external irradiation in the few cases of more aggressive tumours. Thyroglobulin measurement using radioimmunoassay is recommended for follow-up. (orig.) [de

    We report 5 cases of insular carcinoma of the thyroid. Most patients were females (80%) with an age range of 28 to 75 years. Treatment consisted of total or near total thyroidectomy plus modified cervical lymph node dissection in cases with lymph node metastasis. This was followed by radioiodine therapy and external radiation therapy in patients with residual disease. None of the patients had distant metastasis. However, three patients with involvement of the perithyroid soft tissue died within 4 years of the diagnosis. The other two patients are alive without evidence of disease. This type of thyroid carcinoma has an aggresive clinical course with frequent extension to the adjacent soft tissue associated to poor outcomes.

  9. Recombinant TSH in follow-up and therapy of differentiated thyroid carcinoma

    I-131-scintigraphy and serum thyroglobulin testing - if possible under stimulation of thyrotropin - are besides physical examination and ultrasonography crucial for the optimal follow-up of patients with well-differentiated thyroid carcinoma. This required physicians to withdraw patients from thyroid hormone suppression therapy (THST) for several weeks in order to raise endogenous TSH-levels. Clinical hypothyroidism often results in substantial patient discomfort, with sometimes major psychic alterations; the subsequent disability to work is occasionally an unpleasant consequence from an economical point of view. The temporary use of bovine, and for a short period of time human TSH is obsolete today because of a high risk of allergic reactions or the potential transmission of the Creutzfeldt-Jakob disease, respectively. Lately recombinant human TSH (rhTSH, Thyrogen trademark ), a hormone that was developed with the help of genetic engineering techniques, is available; its pharmacological safety has been demonstrated in previous phase-I/II-studies. The results of a phase-III-study showed in the majority of patients a marked rise in thyroglobulin levels after rhTSH. In all cases an adequate TSH level (>100 mU/l) was achieved after i.m. injection of recombinant TSH. Wholebody-scans showed a high level of accordance (>90%) in addition to a substantially lower background-activity. A tumour-background-ratio corresponding to conventional imaging could be demonstrated. (orig.) [de

    Full Text Available BRAF is mutated at a high frequency in various malignancies, including melanoma, papillary thyroid carcinoma and colorectal adenocarcinoma. BRAF is an element of the RAS/RAF/MEK/ERK (MAPK pathway, which when constitutively active can lead to increased proliferation rate, enhanced survival, invasion and metastasis. The development of small molecule inhibitors of mutant BRAF kinase has changed the care of patients, especially with melanoma. Despite the success in treating melanoma with inhibitors of mutant BRAF and other elements of RAS/RAF/MEK/ERK (MAPK pathway, resistance limits the long-term responsiveness to these drugs. The resistance mechanisms to MAPK pathway inhibition are complex, occur at genomic and phenotypic levels, and frequently the same patient can simultaneously develop diverse mechanisms of resistance in different progressive metastases or even in the same lesion. In the current review, we summarize recent research on mutations in BRAF and their importance for the development of tumor. This review will also give an overview on the current knowledge concerning therapies for patients harboring mutation in BRAF and discusses the diverse mechanisms of resistance developed in response to these targeted therapies.

    Benua, Leeper, and others (BEL) have advocated the estimation of radiation exposure to the blood to select a more rational maximum safe dose of radioiodine (dosimetry) to treat metastatic functioning well-differentiated thyroid carcinoma. After adopting the BEL dosimetry approach, we reviewed the immediate (during hospitalization) and intermediate (from discharge up to 3 mo) side effects after our initial 15 therapies in ten patients. The doses ranged from 51 mCi (1887 MBq) to 450 mCi (16.65 GBq). Immediate side effects were observed in 12/15 (80%), are described in detail, and were as follows: gastrointestinal 10/15, salivary 9/15, nonsalivary neck pain, swelling, etc. 2/15, pulmonary 0/15. Intermediate side effects were observed in 10/15 (67%), are described in detail, and were as follows: gastrointestinal 0/15, salivary 3/15, nonsalivary neck pain, swelling, etc. 3/15, nasal complaints 2/15, transient bone marrow suppression 9/10, pulmonary 0/15. No patient required blood transfusions or had complications secondary to reduced blood counts. All patient complaints resolved; however, several patients may have reduced baseline blood counts one year after therapy. No other long-term side effect has been noted but the mean follow-up has been only 15 mo. In our opinion, we have not observed any side effect to date which would contraindicate the continued use and evaluation of the BEL dosimetry approach

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

    The maximal safe dose (MSD) on the basis of bone marrow irradiation levels allows the delivery of a large amount of I-131 to thyroid cancer tissue. The efficacy of MSD therapy in differentiated metastatic thyroid cancers that persisted after conventional fixed dose therapy is investigated. Forty-seven differentiated thyroid carcinoma patients with non-responsive residual disease despite repetitive fixed dose I-131 therapy were enrolled in this study. Their postoperative pathologies were 43 papillary carcinomas and 4 follicular carcinomas. The MSD was calculated with the Memorial Sloan-Kettering Cancer Center protocol using serial blood samples. The MSDs were administered at intervals of 6 months. Treatment responses were evaluated using I-131 whole-body scans and serum thyroglobulin measurements. The mean calculated MSD was 12.5±2.1 GBq (339.6±57.5 mCi). Of the 46 patients, 7 (14.9%) showed complete remission, 15 (31.9%) partial remission, 19 (40.4%) stable disease, and 6 (12.8%) disease progression. Of the patients who showed complete or partial remission, 15 (65%) showed response after the first MSD session and 6 (26%) showed response after the second session. Twenty-nine patients (62%) experienced transient cytopenia after therapy, but three did not recover to the baseline level. The maximal safe dose provides an effective means of treatment in patients who failed to respond adequately to conventional fixed dose therapy. I-131 MSD therapy can be considered in patients who fail fixed dose therapy. (author)

    A 70-year-old woman presented with a nodule in the thyroid gland. /sup 131/I scintigraphy of the gland showed a hot nodule. Histology of the resected thyroid revealed a papillary adenocarcinoma. Although a thyroid carcinoma with a hot nodule seen on the radioiodine isotope scan is a very rare occurrence, it is clinically very important because it may indicate a thyroid malignancy.

    Subclinical thyroid dysfunctions may cause cognitive deficits and mood disorders. Chronic TSH-suppressive therapy with L-T(4) causing subclinical hyperthyroidism has been widely used in treatment of patients with thyroid differentiated carcinoma. The impact of this therapy on cognitive functions and mood have not been systematically studied. The aim of this study was to asses executive functions, working memory, attention, and depression in patients with subclinical hyperthyroidism in the course of TSH-suppressive therapy. Thirty-one patients with subclinical hyperthyroidism in the course of suppressive treatment with L-T(4) following the total thyroidectomy and radioiodine ablative therapy were included in the study. Cognitive functioning in patients and control group were investigated using the battery of neuropsychological tests [Wisconsin Card Sorting Test (WCST), The Oral Word Association Test (OWAT), Trail Making Test, The Stroop Color-Word Interference test and Digit span]. Psychometric evaluation was performed using 17-items the Hamilton Depression Rating Scale (HDRS) and Beck Depression Inventory (BDI). The performance on tests assessed executive functions, psychomotor speed, and attention was significantly lower in patients group. There was no differences in results of Stroop test and Digit Span forward and backwards between both groups. The intensity of depressive symptoms negatively correlated with a number of completed categories on WCST and results of OWAT. Cognitive deficits were still observed when patients with concomitant general medical conditions and depression were excluded from the analysis. Our findings provide evidence of neuropsychological impairment in patients with differentiated thyroid carcinoma treated with chronic TSH-suppressive therapy.

    Full text: Since 1985, the department of nuclear medicine of IBN SINA Hospital in the Rabat University hospital centre is the only centre in Morocco, where all patients of differentiated thyroid carcinoma after surgery are treated with 3.7 GBq of Iodine-131. The number of patients on follow-up is more than two thousands. The endemic zone represents the main origin of thyroid carcinoma. The sex ratio (F/M) is 3.5/1; the mean age is 42.5 years. The papillary carcinoma constitutes about 65.5% of the 26% of well-differentiated carcinoma and 12.5 of moderately differentiated carcinoma (MDC). The tumour size at diagnosis was more than 2 cm in 70% of cases. Prognosis factors are the age, the histology and tumour size. After the surgery, the patients receive 131-Iodine therapy (3.7 GBq) and a regular follow-up by clinical examination, neck ultrasonography and thyroglobulin (Tg) blood level. The aim is to obtain a negative whole body scan (WBS) and undetectable Tg. All the patients also receive a suppressive hormone therapy (thyroxin: 2.4 μg/kg/day). In the same patient, the Tg level is also compared with and without suppression therapy, but taking TSH levels into account. The efficiency of 131-Iodine treatment and the following up, depends on the type of patients: (a) Patients without metastasis: the success of Iodine-131 therapy depended on surgery and it was more than 92% (b) Patients with local metastasis to lymph nodes: the success of 131-Iodine therapy depended of nodal status and complete dissection is possible in 70% cases only. (c) Patients with distant metastasis: The efficiency of 131-Iodine therapy depended on the uptake, the homogeneity and the size of metastasis. In lung metastasis, the efficiency of 131-Iodine is about 40-42% (70%: miliary and micro nodules) and only 6.6% in bone metastasis. After treatment, the patients were regularly followed-up clinically till the next WBS and Tg estimation. In some cases, it was interesting to compare WBS and MIBI

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

    Background: Previously, we have started to study the mechanisms of DNA damage and repair induced by BNCT in thyroid carcinoma some years ago. We have shown different genotoxic patterns for tumor cells irradiated with gamma rays, neutrons alone or neutrons plus different compounds, boronophenylalanine (BPA) or α, β - dihydroxyethyl)-deutero-porphyrin IX (BOPP). In the present study we analyzed the expression of Ku70, Rad51 and Rad54 components of non homologous end-joing (NHEJ) and homologous recombination repair (HRR) pathways, respectively, induced by BNCT in human cells of thyroid carcinoma. Methods: A human cell line of follicular thyroid carcinoma (WRO) in exponential growth phase was distributed into the following groups: 1) Gamma Radiation, 2) Radiation with neutrons beam (NCT), 3) Radiation with n th in presence of BPA (BNCT). A control group for each treatment was added. The cells were irradiated in the thermal column facility of the RA-3 reactor (flux= 1.10 10 n/cm 2 sec) or with a source of 60 Co. The irradiations were performed during different lapses in order to obtain a total physical dose of 3 Gy (±10%). The mRNA expressions of Ku70, Rad 51 and Rad 54 were analysed by reverse transcription-polymerase chain reaction (RT-PCR) at different times post irradiation (2, 4, 6, 24 and 48 h). DNA damage was evaluated by immunofluorescence using an antibody against the phosphorylation of histone H2AX, which indicates double strand breaks in the DNA. Results: The expression of Rad51 increased at 2 h post-irradiation and it lasted until 6 h only in the neutron and neutron + BPA groups (p<0.05). Rad54 showed an up-regulation from 2 to 24 h in both groups irradiated with the neutron beam (with and without BPA) (p<0.05). On the other hand, Ku70 mRNA did not show a modification of its expression in the irradiated groups respect to the control group. Conclusion: these results would indicate an activation of the HRR pathway in the thyroid carcinoma cells treated by

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

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

    Several studies have evidenced the association between subclinical hyperthyroidism and cognitive impairment in the elderly. However, the effect of long-term TSH suppressive therapy on the cognitive function in elderly patients with differentiated thyroid carcinoma (DTC) is still unclear. Our aim was to investigate the effect of long-term TSH suppression on the cognitive function of elderly patients with DTC. A cross-sectional case-control study including 50 DTC patients aged 65 years or older (mean age 70.9 ± 5.0 y) who have received a TSH-suppressive therapy for at least 5 years and 90 control subjects matched for age, sex, education period, and depressive mood was conducted. Major Outcome Measure: Comprehensive cognitive domains were compared between the patient and control groups. The association between serum thyroid hormone concentration and cognitive function was investigated. The patient group had higher serum free T4 levels and suppressed TSH levels compared with the control group. Age, sex, education period, the Korean version of the Geriatric Depression Scale scores, and Cumulative Illness Rating Scale scores were not different between the 2 groups. All assessed neuropsychiatric tests were comparable in both groups. In the patient group, those with higher serum free T4 levels performed better on Mini-Mental State Examination and Trail Making Test A. The association between serum free T4 and Trail Making Test A was maintained after adjusting for age, education period, the Korean version of the Geriatric Depression Scale, and Cumulative Illness Rating Scale. In the control group, serum free T4 and TSH levels were not associated with any of the assessed cognitive domains. Our results demonstrated the safety of long-term TSH suppression on the cognitive function in elderly DTC patients. Furthermore, the positive correlations between serum free T4 levels and some cognitive domains suggest the potential beneficial effects of exogenous levothyroxine on the

    The risk of thyroid carcinoma induction, due to external or internal exposure of the thyroid, is described and quantified. A modified absolute risk model is used. The assessment is based on a risk coefficient of 2.5 induced cases per million persons per cGy per year of risk, derived from US-investigations in persons who had received external radiation therapy during childhood for treatment of benign diseases. This value is considered to be suitable for a dose range of 0.06-15 Gy. Modifying factors are given for age at exposure, gender and relative effectiveness of various radiation sources. The minimum induction period is taken to be 5 years; the remaining life expectancy minus minimum induction period is considered as the number of years at risk. For external exposure of the general public, a calculated incidence for lethal thyroid carcinoma of 7.5 cases per million persons per cGy thyroid dose for the total life time may be derived from the average life expectancy, the age distribution of the population and a mortality of radiation induced thyroid carcinoma of 10%. This figure is in good agreement with earlier estimates. (orig./ECB) [de

A comparison of lesional radiation absorbed dose, hospital stay, renal function tests, and symptom profile was undertaken between the traditional thyroid hormone withdrawal protocol and rhTSH-based therapy protocol. Dosimetric calculations of metastatic lesions were performed using lesion uptake and survey meter readings for calculation of effective half-life. Non-contrast-enhanced CT was used for assessment of tumor volume. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL forms. A comparison of pretreatment withdrawal thyroglobulin (TG) was done with the withdrawal TG level 3 months after treatment. The mean effective half-life of (131)I in metastatic lesions was less during the rhTSH protocol (29.49 h) compared to the thyroid hormone withdrawal protocol (35.48 h), but the difference was not statistically significant (p = 0.056). The mean 24-h % uptake of the lesions during the traditional protocol (4.84 %) was slightly higher than the 24-h % uptake during the rhTSH protocol (3.56 %), but the

    Full Text Available Parafollicular C-cell-derived medullary thyroid cancer (MTC comprises 3% to 4% of all thyroid cancers. While cytotoxic treatments have been shown to have limited efficacy, targeted molecular therapies that inhibit rearranged during transfection (RET and other tyrosine kinase receptors that are mainly involved in angiogenesis have shown great promise in the treatment of metastatic or locally advanced MTC. Multi-tyrosine kinase inhibitors such as vandetanib, which is already approved for the treatment of progressive MTC, and cabozantinib have shown distinct advantages with regard to rates of disease response and control. However, these types of tyrosine kinase inhibitor compounds are able to concurrently block several types of targets, which limits the understanding of RET as a specific target. Moreover, important resistances to tyrosine kinase inhibitors can occur, which limit the long-term efficacy of these treatments. Deregulated cellular signaling pathways and genetic alterations in MTC, particularly the activation of the RAS/mammalian target of rapamycin (mTOR cascades and RET crosstalk signaling, are now emerging as novel and potentially promising therapeutic treatments for aggressive MTC.

    Chemotherapy alone, either as a single drug or a combination of drugs with or without external radiation (ER) is useful for treatment of locally advanced disease and non iodine concentrating metastasis in differentiated thyroid cancers (DTC). The reported response is not encouraging, but the absence of better alternatives leave no choice for the treatment of such cases. However, for treatment of anaplastic thyroid cancers (ANC), chemotherapy (CT) in combination with ER results in local control. In medullary thyroid cancers (MTC), the results obtained with multimodal treatment are encouraging

    To evaluate the effect of adjuvant external beam radiation therapy (EBRT) on local failure-free survival rate (LFFS) for papillary thyroid cancer (PTC) invading the trachea. Fifty-six patients with locally advanced PTC invading the trachea were treated with surgical resection. After surgery, 21 patients received adjuvant EBRT and radioactive iodine therapy (EBRT group) and 35 patients were treated with radioactive iodine therapy (control group). The age range was 26–87 years (median, 56 years). The median follow-up period was 43 months (range, 4 to 145 months). EBRT doses ranged from 50.4 to 66 Gy (median, 60 Gy). Esophagus invasion and gross residual disease was more frequent in the EBRT group. In the control group, local recurrence developed in 9 (9/35, 26%) and new distant metastasis in 2 (2/35, 6%) patients, occurring 4 to 68 months (median, 37 months) and 53 to 68 months (median, 60 months) after surgery, respectively. Two patients had simultaneous local recurrence and new distant metastasis. There was one local failure in the EBRT group at 18 months after surgery (1/21, 5%). The 5-year LFFS was 95% in the EBRT group and 63% in the control group (p = 0.103). In the EBRT group, one late grade 2 xerostomia was developed. Although, EBRT group had a higher incidence of esophagus invasion and gross residual disease, EBRT group showed a better 5-year LFFS. Adjuvant EBRT may have contributed to the better LFFS in these patients.

    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 ( 31 P-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. 131 I-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; p 31 P-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 31 P-MRS could be developed as an additional diagnostic tool for the follow-up of differentiated thyroid cancer. (author)

    Full Text Available Background. Renal cell carcinoma (RCC has unpredictable and diverse behavior. The classic triad of hematuria, loin pain, and abdominal mass is uncommon. At time of diagnosis, 25%–30% of patients are found to have metastases. Bones, lungs, liver, and brain are the frequent sites of metastases. RCC with metastasis to the head and neck region and thyroid gland is the rarest manifestation and anaplastic carcinoma behaving metastatic thyroid mass is an extremely rare presentation of RCC. Case Presentation. A 56-year-old Saudi man with past history of right radical nephrectomy 5 years back presented with 3 months history of rapid increasing neck mass with dysphagia, presenting like anaplastic thyroid carcinoma. Tru-cut biopsy turned out to be metastatic renal cell carcinoma. Patient was treated with radiation therapy 30 Gy in 10 fractions to mass. Patient died 4 months after the discovery of anaplastic thyroid looking metastasis. Conclusion. Rapidly progressing thyroid metastases secondary to RCC are rare and found often unresectable which are not amenable to surgery. Palliative radiotherapy can be considered for such patients.

    Medullary thyroid carcinoma is a biologically distinct form of thyroid cancer and accounts for 5-10% of all thyroid neoplasms. Twenty percent of MTC can occur in a familial setting either by itself or as part of the multiple endocrine neoplasm syndromes. A disciplined approach is necessary in the work-up of these patients to rule out coexistent endocrine tumors (pheochromocytomas and parathyroid). Cacitonin is a sensitive tumor marker secreted by MTC that is of prognostic value and important in the follow-up of patients. Surgery is the mainstay of treatment with a total thyroidectomy and centre compartment clearance being the minimum for patients without cervical adenopathy. Radiotherapy has a limited role and is only indicated as a palliative measure in patients with advanced/metastatic disease not amenable to surgery

    In patients with advanced differentiated thyroid carcinoma (DTC), therapy with the highest safe 131 I activity is desirable to maximize the tumour radiation dose yet avoid severe myelotoxicity. Recently, the European Association of Nuclear Medicine (EANM) published a standard operational procedure (SOP) for pre-therapeutic dosimetry in DTC patients incorporating a safety threshold of a 2 Gy absorbed dose to the blood as a surrogate for the red marrow. We sought to evaluate the safety and effectiveness in everyday tertiary referral centre practice of treating advanced DTC with high 131 I activities chosen primarily based on the results of dosimetry following this SOP. We retrospectively assessed toxicity as well as biochemical and scintigraphic response in our first ten patients receiving such therapy for advanced DTC. The 10 patients received a total of 13 dosimetrically guided treatments with a median administered activity of 14.0 GBq (range: 7.0-21.4 GBq) 131 I. After 6 of 13 treatments in 6 of 10 patients, short-term side effects of 131 I therapy, namely nausea, vomiting or sialadenitis, were observed. Leukocyte and platelet counts dropped significantly in the weeks after 131 I treatment, but returned to pre-treatment levels by 3 months post-therapy. Serum thyroglobulin levels decreased after 12 of 13 treatments (median reduction: 58%) in 9 of 10 patients. In our initial patient cohort, high-activity 131 I therapy for advanced DTC based on pre-therapeutic blood dosimetry following the EANM SOP was safe and well tolerated. Such treatment almost always produced a partial biochemical tumour response. (orig.)

    2013-05-01

    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

    Purpose: To report the finding of nasolacrimal drainage system obstruction associated with radio iodine therapy and to review clinical data and the surgical treatment outcome of this rare complication. Methods: We retrospectively analyzed ophthalmological data of patients with history of thyroid carcinoma that underwent radioactive iodine I-131 therapy and were referred to lacrimal surgery. Results: 17 patients with thyroid cancer treated with thyroidectomy and radioactive iodine I-131 therapy presented symptomatic nasolacrimal duct obstruction after 13.2 months following cancer treatment. 11 patients presented bilateral epiphora, 8 had lacrimal sac mucocele. Age range was 30 to 80 years, 10 patients had less than or equal to 49 years. The mean cumulative dose of radioiodine was 571mCi (range: 200-1200 mCi). Nasal obstruction symptoms and increased salivary glands were also present in 53% of patients. All subjects underwent dacryocystorhinostomy. Dilation of the lacrimal sac and increased intraoperative bleeding was also observed in 3 younger patients. Complete epiphora and dacryocystitis resolution after surgery occurred in 82.4%, and partial in 17.6% (3 patients that still presented unilateral relapse after correction of bilateral obstruction). Mean follow-up was 6 months (range: 2-24 months). Conclusions: Cumulative high dose of radioiodine, nasal and salivary gland dysfunction are associated with lacrimal drainage obstruction. We observed a great percentage of younger patients presenting dacryocystitis when compared to the idiopathic dacryostenosis. Radioactive iodine uptake by nasolacrimal duct mucosa with subsequent inflammation, edema and fibrosis seems to have a relationship to lacrimal duct obstruction. The knowledge of this complication is important for the study and proper management of these patients (author)

    The validity of the indication of treatment with I131 as part of the management of differentiated thyroid cancer, was analyzed in patients older than 16 years attended in Hospital San Juan de Dios and Hospital Mexico, who received this therapy, during the years 2006-2009. The medical records of the selected patients were reviewed and registered in the SPSS statistical program. The following variables were obtained: name, file number, age, gender, type of cancer, maximum diameter of the tumor, presence of one of 2 or more tumor foci in the surgical piece, hospital of origin, value of T, N and M according to the TNM staging, MACIS scale score and staging according to the MACIS score. The most common differentiated carcinoma in the studied population was papillary carcinoma. A little less than half of the patients, had the criteria to receive radioiodine therapy according to that established by the ATA, same result when said population was subjected to European criteria Criteria to receive radioiodine dictated by the American school as the European one were fulfilled in the majority of patients with stage 2. Compliance with indication or non-indication of treatment was maintained without significant difference between papillary and follicular carcinomas [es

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

Here, we summarize an up-to-date review of the literature on genetics, diagnosis (ultrasound scan, fine needle aspiration, frozen section, etc., and management. At presentation, treatment decision should be made by a multidisciplinary board. Recurrent HCCs are seldom curable despite salvage treatments, which include radioactive iodine ablation, radiofrequency ablation, ethanol ablation, external radiotherapy, and systemic therapy. Further research is needed to develop more efficacious systemic treatments. Currently, lenvatinib, sunitinib, and sorafenib are available.

    Full text: A serum TSH level of > 30 mU/L, which is necessary for reliable testing and efficient radioiodine therapy in patients with differentiated thyroid carcinoma, may be achieved by: a 4-6 weeks L-thyroxine withdrawal or by application of recombinant human TSH (rh TSH).The purpose of our study was to test the efficacy of 131-I therapy (RAIT) using recombinant human TSH (rhTSH) as an alternative in patients with differentiated thyroid carcinoma (DTC) in whom endogenous TSH stimulation was not an option due to the poor patient's physical condition during the hypothyroid state or due to the disease progression during L-thyroxine withdrawal. The study comprised 14 patients (12 females, 2 males, aged 63- 81, median 73 years), with histologically proven DTC, in whom the primary diagnosis was established 1993-2000, who already have undergone total or near-total thyroidectomy and who have received radioiodine ablation and 3-12 (median 6) RAITs after L-thyroxine withdrawal, with a cumulative dose ranging 15.65- 68.34 GBq. Patients were given 28 RAITs (7/14 patients received two, 2 received 3 and 1 received 4) while on L-thyroxine after rhTSH administration (rhTSH RAIT). RhTSH (0.9 mg, i.m.) was administered on two consecutive days, followed by 131-I therapeutic dose (5.2-7.6 GBq) administration on the third day and a post-therapeutic whole-body scan (PTWBS) 2-5 days later. The efficacy of rhTSH RAIT was evaluated by thyroglobuline (Tg) measurement 3 - 6 months after rhTSH RAIT. Serum TSH levels after rhTSH administration were 61 - 305 mU/l. Altogether 36 131-I-avid lesions were detected on PTWBS. In one patient who underwent two rhTSH RAITs a decrease of 131-I uptake in one lesion was seen on the second PTWBS. In all patients serum Tg concentrations were elevated before rhTSH RAIT (25 -17248 ng/ml). Three months after therapy serum Tg decreased by 24 -91% in 6 cases (4 patients), in 3 patients serum Tg stagnation was achieved, while in 7 cases the disease progressed

    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.

    Thyroid-associated orbitopathy (TAO) is most often seen in patients with autoimmune thyroid disease. Data about TAO occurred in patients with thyroid carcinoma are rare. We give a report of 5 patients to present the clinical characteristics, treatment, and prognosis of this type of case. Five thyroid carcinoma patients presented with orbitopathy. Among them, two patients (patient 1 and 4) were hyperthyroid and TSH receptor antibody (TRAb) positive, two patients (patient 3 and 5) were euthyroid and displayed slightly elevated TRAb titres, one patient (patient 2) was euthyroid and TRAb negative. They were diagnosed as thyroid carcinoma and TAO. Patient 1 underwent total thyroidectomy, intravenous glucocorticoids (GCs) therapy, orbital decompression surgery and oral GCs therapy. Patient 2 and 3 only received total thyroidectomy. Patient 4 received sub-total thyroidectomy and oral GCs therapy. patient 5 didn't received thyroidectomy and underwent intravenous GCs therapy for 2 courses. Patient 1,2,3 showed an improvement of TAO at the final follow-up. Patient 4,5 showed no improvement of TAO at the final follow-up. When TAO present in patients with thyroid nodules, the possibility of thyroid carcinoma should be considered, and the nature of these nodules should be carefully evaluated. In some patients with thyroid carcinoma and TAO, the remission of TAO can be seen post total thyroidectomy. But for other patients, besides thyroidectomy, an adequate dose and course of intravenous GCs treatment and even ocular surgery are also needed. Copyright © 2017 The Authors.

    Targeted radionuclide therapy is being increasingly used in malignancies. According to regulatory requirements patient-specific dosimetry must be performed in the context of any radiotherapeutic procedure. A calculatory model is presented demonstrating how to individualize radionuclide therapy through dosimetric data by weighing the success of therapy against risk. The model is exemplarily implemented for radioiodine therapy of differentiated thyroid carcinoma (DTC). For DTC dose-response relationships were retrieved from the literature. From these data a three-variable model was developed which consists of a target variable weighing response against risk, a measured variable representing the lesion dose per activity [LDpA, in units gray per gigabecquerel (Gy/GBq)] and a manipulated variable constituting the therapeutic activity. Dosimetry-related radioiodine therapy along the three-variable model increases response probability in individual patients by up to > 50% (e.g. from 18 to 72% at a LDpA of 6 Gy/GBq) compared to ''standard'' therapy with 7 GBq. On a patient population scale, by escalating and de-escalating activity along the model, the overall response rate can be enhanced by 8% (62 vs 70%) while saving on average 0.9 GBq per patient (7 vs 6.1 GBq). Redistribution of therapeutic activities along the model, i.e. taking into account success and risk, may enhance response while on average saving activity as exemplarily shown by a virtual comparison with standard approaches using literature data from DTC for implementation. The model may thus provide a guideline for the prescription of therapeutic activities; the results underline the potential impact of individual dosimetry in radionuclide therapy. (orig.)

    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

    The aim of this study was to investigate if intravenous contrast injection affected the radiation doses to carotid arteries and thyroid during intensity-modulated radiation therapy (IMRT) planning for nasopharyngeal carcinoma (NPC). Thirty consecutive patients with NPC underwent plain computed tomography (CT) followed by repeated scanning after contrast injection. Carotid arteries (common, external, internal), thyroid, target volumes, and other organs-at-risk (OARs), as well as IMRT planning, were based on contrast-enhanced CT (CE-CT) images. All these structures and the IMRT plans were then copied and transferred to the non-contrast-enhanced CT (NCE-CT) images, and dose calculation without optimization was performed again. The radiation doses to the carotid arteries and the thyroid based on CE-CT and NCE-CT were then compared. Based on CE-CT, no statistical differences, despite minute numeric decreases, were noted in all dosimetric parameters (minimum, maximum, mean, median, D05, and D01) of the target volumes, the OARs, the carotid arteries, and the thyroid compared with NCE-CT. Our results suggested that compared with NCE-CT planning, CE-CT scanning should be performed during IMRT for better target and OAR delineation, without discernible change in radiation doses.

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

    The association between chronic lymphocytic thyroiditis (CLT) and thyroid cancer is an interesting topic. The aim of the present study was to evaluate if demographic and histological characteristics as well as the long-term outcome of thyroid cancer was different in children and adolescents with and without CLT. The medical records of children and adolescents (≤21 years old) were reviewed. The following data were recorded: gender, year and age at diagnosis, family history of thyroid cancer, history of external radiation therapy, histological type (papillary and variants, follicular and variants), tumour size, multifocality, infiltration of thyroid parenchyma or surrounding soft tissues, vascular invasion, presence of lymph node and distant metastases. Information about the presence of TgAb and TPOAb was also collected. One hundred eight children and adolescents (median age 19.0, interquartile range 4.0 years) were diagnosed with differentiated thyroid carcinoma (DTC); 31 patients (28.7%) presented histological characteristics compatible with CLT. Infiltration of thyroid parenchyma was more frequent in patients with CLT compared to patients without (74.2% vs 48.1% respectively, P=0.024). Familial papillary thyroid carcinoma (PTC) was more frequent in patients with CLT compared to those without CLT (20.7% vs 2.8% respectively, P=0.009). There was no better outcome with respect to the presence of CLT or not. Children and adolescents with CLT present more frequently familial PTC as well as thyroid cancer with invasive characteristics. © 2015 European Society of Endocrinology.

    Improved selection of thyroid nodules for surgery and greater individualization of surgery for well-differentiated thyroid carcinoma are emphasized. Thyroid nodules are common but infrequently are manifestations of carcinoma. Needle biopsy permits better selection of patients with thyroid nodules for surgery by identifying those which are malignant or are likely to become malignant. Experience in performing diagnostic needle biopsies and in cytologic and histologic interpretation is essential. The majority of well-differentiated thyroid carcinomas are well-localized papillary carcinomas controlled by surgery, usually a lobectomy or partial thyroidectomy. Well-differentiated thyroid carcinomas include papillary and follicular types and their subsets. The extent of surgery should be individualized based on gross extent of disease, histologic variety, and age of the patient. The prognosis is reduced for patients more than 40 years of age. With appropriate early surgical treatment, the outlook is excellent. Metastatic disease can frequently also be controlled by large doses of thyroid hormone and the use of radioactive iodine

    Primary thyroid exploration is to find the rare malignant nodule (in Germany 1/1000 in all nodular thyroids), which is capable to decrease significantly life quality and survival rate. Cervical sonography as basic examination determines the following steps with scintigraphy in nodules > 10 mm, aspiration fine needle biopsy in ''cold'' nodules and thyroidectomy in case of finding malignant cells. After surgical resection of organoid thyroid tumors and ablation of residual tissue by radioiodine follow-up is possible by sonography and serum thyreoglobulin. In case of relapse high dose radioiodine offers highly effective curative therapy of tumor and/or metastases, when the malignant tissue is avid for radioiodine. Compared to {sup 131}I-scintigraphy is PET-CT with {sup 124}I clearly superior because of better spatial resolution, precise localisation even of small metastases und new technical approaches for individual dosimetry. In case of increasing serum thyroglobuline levels and radioiodine negative metastases as well as in case of increasing serum calcitonin levels after medullary carcinoma, {sup 18}F-FDG-PET or -PET-CT is well suited as an alternate diagnostic approach. Radiolabelled somatostatin analogues may serve as diagnostic as well as therapeutic agents. (orig.)

    The link between Hashimoto's thyroiditis and thyroid carcinoma has long been a topic of controversy. The aim of our study was to determine the prevalence of thyroid carcinoma and Hashimoto's thyroiditis coexistence in histopathologic material of thyroidectomized patients. In a retrospective study, the clinicohistopathologic data of 2117 patients (1738 females/379 males), who underwent total or partial thyroidectomy for thyroid gland disorder at a single institution from the 1st of January 2005 to the 31st of December 2014 were analyzed. Thyroid carcinoma was detected in 318 cases (15%) and microcarcinoma (thyroid cancer ≤10mm in diameter) was found in permanent sections in 169 cases (8%). Hashimoto's thyroiditis was detected in 318 (15%) patients. Hashimoto's thyroiditis was significantly more often associated with thyroid carcinoma and microcarcinoma compare to benign condition (p=0.048, p=0.00014, respectively). Coexistence of Hashimoto's thyroiditis and thyroid carcinoma/thyroid microcarcinoma did not affect tumor size (p=0.251, p=0.098, respectively), or tumor multifocality (p=0.831, p=0.957, respectively). Bilateral thyroid microcarcinoma was significantly more often detected when Hashimoto's thyroiditis was also diagnosed (p=0.041), but presence of Hashimoto's thyroiditis did not affect bilateral occurrence of thyroid carcinoma (p=0.731). Hashimoto's thyroiditis is associated with significantly increased risk of developing thyroid carcinoma, especially thyroid microcarcinoma.

    Familial Adenomatous Polyposis, Cowden's Syndrome, and Peutz-Jeghers Syndrome are well known as Intestinal Polyposis Syndromes, inherited conditions characterized by the development of polyps of the gastro-intestinal tract in association with extra-intestinal manifestations, in particular malignant tumors at different sites. Thyroid carcinoma is sometimes a part of the clinical picture of these syndromes. The aim of this paper is to review the literature dealing with the association between differentiated thyroid carcinomas and Intestinal Polyposis Syndromes in order to point out peculiar aspects, providing suggestions for the screening and the management of thyroid tumors in these patients.

    Between 1971-1989, 59 patients received external radiation therapy with a curative intent. There were 25 females and 34 males, ranging in age from 19 to 87. No patient had distant metastases at the onset of treatment. The majority had a total thyroidectomy (55/59), generally combined with neck dissection. Residual tumor was left in 11 cases, and 44 had positive cervical nodes. Using megavoltage radiotherapy, the whole neck and upper mediastinum area were most often irradiated through a large anterior Y-shaped field without laryngeal shielding. The mean dose to the tumoral bed was 54 Gy. Dysphagia was observed in 32 patients (11, 17 and 5 scores were grade 1, 2 and 3 respectively). Dyspnea occurred in 5 cases and in 2 of these, it was considered to be severe. Local recurrences were noted in 19 (30%) patients, most of them occurring within the fields of irradiation. Parameters such as age, sex, total dose, irradiated volumes or cervical node enlargement did not modify local control rate. Same conclusions can be drawn for distant failures. Thirty-five patients are still alive and among them, 24 have no evidence of disease. Average length of survival is 70.5 months and is shortened by the occurrence of distant failures except in patients with bone metastases. (author). 13 refs.; 1 fig.; 6 tabs

    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

    To analyze the effect of long-term thyroid-stimulating hormone (TSH) suppressive therapy on the gonadal hormones and related symptoms in patients after surgery. From 2008 to 2011, totally 238 patients were recruited, who underwent thyroid surgery and subsequent TSH suppression treatment in Department of thyroid Surgery, China-Japan Union hospital, Jilin University. Then their postoperative follow-up data (3-8 years) were collected, including operational method, pathological diagnosis, whether processed radioiodine therapy and the period/dose of TSH suppression treatment. In addition, the menstrual cycle, menstruation quantity, whether accompanied with dysmenorrheal and menstrual disorder or not, date of last menstrual period, ages of menopause and so on were also collected. (I) Neither the level nor the duration of TSH treatment had any function on estradiol (E2) and testosterone (T) in male patients; (II) in the subgroup of patients with TSH treatment for 3-5 years, patients who took high dose of TSH (TSH ≥0.5 U/L) obtained the lower T level compared with the group of medium dose (1.08±0.34 vs. 1.36±0.46 nmol/L, P=0.001); (III) in the medium dose (0.1 IU/L ≤ TSH hormone (FSH) did not show any change in terms of the dose and the duration of TSH treatment; (V) the menstrual volume, dysmenorrhea condition, menstrual cycle and menopause related indicators did not show any difference in terms of doses and duration of TSH treatment (P=0.701, 0.412 and 0.507 respectively). The long term of TSH repressive therapy after surgery did not affect T and E2 level in male patients. As for female patients, the impact was mainly reflected in the T and E2 levels especially in female sexual maturity but not FSH level. In addition, TSH treatment did not play any role on menstruation or menopause.

    In a retrospective study, the hematologic parameters of 296 patients treated with iodine-131 (average: 536 mCi) for carcinoma of the thyroid gland were evaluated with respect to the different doses applied. The average observation period was 65 months. The most frequent hematologic modification was thrombocytopenia which was found in 35%, followed by erythrocytopenia in 24% of cases. The normal concentration of leucocytes was decreased in 11% and increased in 23% of cases, however, the medium value calculated for all patients showed a decrease of leucocytes by 7%. Pancytopenias were found in 4,4% of cases. The most severe decreases were presented after high doses of radio-iodine (≥ 1000 mCi). Pancytopenia may be considered as one of the causes of the death of three patients. (orig.) [de

    In order to assess the genotoxic risk of the therapy with radioiodine-131(''131I), the production of micronuclei (MN) and chromosome aberrations (CA) were analyzed in the peripheral blood lymphocytes of group of 26 patients undergoing therapy with this radionuclide for differentiated thyroid carcinoma (DTC). Blood samples were taken immediately before ''131 I administration and 1 month later. The patients underwent radioiodine ablation (RIA) or radioiodine therapy (RIT) after radical thyroidectomy. The amount of orally administered ''131I activity varied from 3330 to 4030 MBq according to the king of therapy (RIA or RIT). results show that after radioiodine therapy there is a significant increase in the frequency of MN and CA. The mean frequencies of MN {+-} Sd before and after the therapy were 10.72 % {+-} 5.84 % and 25.28 %{+-} 12.6% respectively. For CA, the mean frequencies obtained were 1.16% {+-} 0.36% before and 2.3% {+-} 0.87% after the therapy. These findings indicate a genotoxic activity of ''131I therapy estimated after a period of one month. (Author) 38 refs.

  4. Cathepsin B trafficking in thyroid carcinoma cells

    2011-08-01

    Full Text Available Abstract Background The cysteine peptidase cathepsin B is important in thyroid physiology by being involved in prohormone processing initiated in the follicle lumen and completed in endo-lysosomal compartments. However, cathepsin B has also been localized to the extrafollicular space in thyroid cancer tissue, and is therefore suggested to promote invasiveness and metastasis in thyroid carcinomas through e.g. extracellular matrix degradation. Methods Transport of cathepsin B in normal thyroid epithelial and carcinoma cells was investigated through immunolocalization of endogenous cathepsin B in combination with probing protease activity. Transport analyses of cathepsin B-eGFP and its active-site mutant counterpart cathepsin B-C29A-eGFP were used to test whether intrinsic sequences of a protease influence its trafficking. Results Our approach employing activity based probes, which distinguish between active and inactive cysteine proteases, demonstrated that both eGFP-tagged normal and active-site mutated cathepsin B chimeras reached the endo-lysosomal compartments of thyroid epithelial cells, thereby ruling out alterations of sorting signals by mutagenesis of the active-site cysteine. Analysis of chimeric protein trafficking further showed that GFP-tagged cathepsin B was transported to the expected compartments, i.e. endoplasmic reticulum, Golgi apparatus and endo-lysosomes of normal and thyroid carcinoma cell lines. However, the active-site mutated cathepsin B chimera was mostly retained in the endoplasmic reticulum and Golgi of KTC-1 and HTh7 cells. Hence the latter, as the least polarized of the three carcinoma cell lines analyzed, exhibited severe transport defects in that it retained chimeras in pre-endolysosomal compartments. Furthermore, secretion of endogenous cathepsin B and of other cysteine peptidases, which occurs at the apical pole of normal thyroid epithelial cells, was most prominent and occurred in a non-directed fashion in thyroid

    Although radiation induced damage to the salivary gland is a known complication of radioactive iodine ((131)I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary glands on nonenhanced CT in postoperative patients with thyroid cancer treated with RIT. Forty patients with thyroid carcinoma, 13 men (age range, 21-80 years) and 27 women (age range, 28-75 years) who underwent a total thyroidectomy and were treated with RIT were assessed retrospectively. On CT, the percentage of volume reduction and the difference in attenuation of the parotid and submandibular glands after RIT were determined and correlated with the extent of radiation-induced salivary dysfunction on scintigraphy. The salivary gland volume significantly decreased with an increase in the dysfunction grade on scintigraphy for both the parotid and submandibular glands (P gland (P gland. The cutoff value of volume reduction to diagnose severe gland dysfunction was 19.5% (sensitivity, 86.0%; specificity, 100%) for the parotid gland and 31.0% (sensitivity, 100%; specificity, 97.0%) for the submandibular gland, and that of the attenuation change was 9.8 HU (sensitivity, 81.0%; specificity, 95%) for the parotid gland. The reduction in volume of the parotid and submandibular glands and the increase in attenuation of the parotid gland on nonenhanced CT can be indicators of the grade of RIT-induced salivary dysfunction.

    I-131-scintigraphy and serum thyroglobulin testing - if possible under stimulation of thyrotropin - are besides physical examination and ultrasonography crucial for the optimal follow-up of patients with well-differentiated thyroid carcinoma. This required physicians to withdraw patients from thyroid hormone suppression therapy (THST) for several weeks in order to raise endogenous TSH-levels. Clinical hypothyroidism often results in substantial patient discomfort, with sometimes major psychic alterations; the subsequent disability to work is occasionally an unpleasant consequence from an economical point of view. The temporary use of bovine, and for a short period of time human TSH is obsolete today because of a high risk of allergic reactions or the potential transmission of the Creutzfeldt-Jakob disease, respectively. Lately recombinant human TSH (rhTSH, Thyrogen {sup trademark}), a hormone that was developed with the help of genetic engineering techniques, is available; its pharmacological safety has been demonstrated in previous phase-I/II-studies. The results of a phase-III-study showed in the majority of patients a marked rise in thyroglobulin levels after rhTSH. In all cases an adequate TSH level (>100 mU/l) was achieved after i.m. injection of recombinant TSH. Wholebody-scans showed a high level of accordance (>90%) in addition to a substantially lower background-activity. A tumour-background-ratio corresponding to conventional imaging could be demonstrated. (orig.)

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

    Full Text Available 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.

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

    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.

In children, 26% of thyroid nodules are malignant, while in adults the corresponding value is 5-10%. Risk factors for developing thyroid nodules in children are female sex, post-pubertal age, previous or co-existing thyroid disease, previous irradiation of the neck, and a family history of thyroid disease. In children younger than 10 years, when no risk factors are present, the incidence rates are practically negligible. A two-year-old girl presented with a right thyroid mass. Laboratory evaluation revealed normal levels of triiodothyronine and thyroid-stimulating hormone. Thyroid ultrasonography revealed a 4.8 × 3.2 × 2.5 cm nonhomogenous nodule. The patient underwent right hemithyroidectomy. The pathology was consistent with papillary thyroid carcinoma; therefore, total thyroidectomy and selective neck dissection were performed. We report a very rare case of papillary thyroid carcinoma in a two-year-old child with no risk factors. The detection of a thyroid nodule in such a young child with no pre-disposing risk factors does not exclude the possibility of thyroid carcinoma and warrants careful evaluation and appropriate therapy.

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

    2002-01-01

    Over half a century, treatment of thyroid autonomy with an oral dose of iodine-131 has proven to be effective. The optimum management strategy for the patient is, however, still a matter of debate. The article provides an overview of the pathogenesis of functional autonomy and its clinical relevance. According to the guidelines on both sides of the Atlantic, radioiodine treatment is considered the most comfortable and economical approach to the treatment of the toxic nodular goitre. Some differences in the preparation procedures in the guidelines of the American and the German Society of Nuclear Medicine are discussed with respect to therapy results and the subtypes of thyroid autonomy. The results of studies are summarised concerning changes in thyroid function and thyroid volume after a course of radioiodine treatment. Therapy-related risks, such as immunogenic hypothyroidism or thyroid cancer, are discussed. 131 I treatment of functional autonomy and hyperthyroidism is considered an effective and safe procedure.

    Novenario, H.S.; Pascacio, F.M.; Cruz, Benjamin de la; Anden, A.B.

    Whole body counters are not only used in measuring radioactivity in the body for radiation protection purposes but also in the measurement of iron absorption, body potassium and cesium, chronic blood loss, and also in the determination of the effectiveness of surgery, thyroid hormone and radioactive iodine therapy in thyroid carcinoma. This report deals with our experience in the use of a shadow-shield whole body counter in the determination of I-131 uptake by metastatic lesions of cancer of thyroid after total thyroidectomy and ablation therapy with I-131. This study was undertaken jointly by the Department of Nuclear Medicine, Veterans Memorial Hospital and the Biomedical Research Division of the Philippine Atomic Energy Commission. Preliminary results indicate that the 22 patients who underwent whole body counting after total thyroidectomy I-131 ablation therapy, 9 patients had elevated percentage retention of I-131, 10 patients with normal values and 3 patients with rising values. Foci of I-131 concentration in those with elevated and rising percentage concentration values were seen in the thyroidal bed scintiscans, while the 10 patients with normal values had negative scintiscans. The results of our observations confirm the results obtained by other workers abroad. Our preliminary results indicate that with the use of whole body counters a sensitive method of assessing whether functioning metastatic lesion of cancer of the thyroid still exist after total thyroidectomy and I-131 ablation therapy can be provided.

    Thyrotoxicosis and well differentiated thyroid carcinomas are the two most common pathological conditions where radioiodine is used. Patients with well differentiated thyroid carcinomas are the candidates for post operative radio iodine therapy. It is currently the most popular and frequently used method of treatment. Its use is safe and cost effective. The results are usually eventless but in some exceptional cases emergencies that occurred after administration of I-131. One emergency occurred after I-131 administration for Graves' disease and the second case happened after therapeutic application of I-131 for treatment of local recurrences of thyroid cancer.(author)

    Metastasis to the thyroid gland from distant cancer is rare, and, in some cases, is a diagnostic challenge. Here, we report a case of metastatic renal cell carcinoma of the thyroid gland. A 77-year-old man presented with a neck mass detected about 1 month previously. He had undergone a right nephrectomy owing to renal cell carcinoma 14 years previously. Fine needle aspiration cytology showed a few atypical follicular cells with nuclear atypia. Under a tentative diagnosis of papillary thyroid carcinoma, a total thyroidectomy was performed. The histologic and immunohistochemical studies of the surgical specimens indicated that the thyroid masses were metastatic renal cell carcinoma to the thyroid.

    Full Text Available Using ultrasound data and content of gonadotropin and sex hormones in the blood, the morphological and functional state of the mammary glands, the uterus and the ovaries were studied in women after thyroidectomy and radioiodine therapy, who were taken suppressive therapy with levothyroxine drugs that allows to estimate the hormonal supply of the menstrual cycle and the state of reproductive system. The signs of menstrual cycle disorders and luteal phase deficiency were revealed during the treatment, and dyshormonal hyperplasia of mammary glands was also diagnosed in 82.6 % of cases due to prolonged relative hyperestrogenism and hyperplastic diseases of the uterus and the ovaries, including genital endometriosis, endometrial hyperplasia, uterine myomas, were identified in 80.4 % of cases. A long-term monitoring (every 3 months of thyroid-stimulating hormone, thyroglobulin, thyroglobulin antibodies, follicle-stimulating hormone, luteinizing hormone, prolactin, progesterone, free testosterone, estradiol levels and also the correction of cycle supply using hormonal and non-hormonal methods are needed for this category of patients.

    Thyroid hormone replacement has been used for more than 100 years in the treatment of hypothyroidism, and there is no doubt about its overall efficacy. Desiccated thyroid contains both thyroxine (T(4)) and triiodothyronine (T(3)); serum T(3) frequently rises to supranormal values in the absorption

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

    To examine the presentation, diagnosis, and appropriate management of renal clear cell carcinoma metastasis to the thyroid gland. We describe a clinical case of solitary thyroid metastasis from renal clear cell carcinoma and present a comprehensive review of the related English-language literature. Common patterns of presentation and generalized overall management recommendations are evaluated and summarized. Eight years after nephrectomy for renal carcinoma at age 61 years, a man presented with a thyroid mass. Cytology and histopathologic surgical findings were consistent with a solitary metastasis most compatible with metastatic clear cell carcinoma from his previous renal carcinoma. After left thyroid lobectomy and isthmusectomy, the patient remains disease-free 5 years later. Although uncommon, nearly 150 cases of clinically recognized metastatic renal cell carcinoma to the thyroid have been reported in the English-language literature. Metastatic disease from the kidney to the thyroid gland can occur more than 20 years after nephrectomy with the average time interval being 7.5 years. Obtaining a full clinical history in any patient who presents with a thyroid nodule is essential to allow consideration of possible metastatic disease from previous primary tumor. Metastatic disease to the thyroid gland can be correctly diagnosed preoperatively. If metastatic renal cancer is limited to the thyroid gland only, prompt, appropriate surgical intervention can be curative. Metastatic renal carcinoma to the thyroid should be considered in any patient presenting with a thyroid mass and a medical history of renal cell carcinoma.

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

    Serum thyroglobulin (Tg) level is frequently elevated shortly after radioactive iodine (RAI) ablation therapy. The authors studied the relationship between the elevation of serum Tg after RAI therapy and iodine uptake pattern on post-ablation whole body scans (RxWBSs) in patients with papillary thyroid carcinoma (PTC). The study subjects were patients with PTC that had undergone first RAI therapy with thyroid hormone withdrawal after total thyroidectomy. Patients with a high level of serum anti-Tg antibody (TgAb, ≥ 60 U/mL), possible regional or distant metastasis as determined by pre-ablation or post-ablation studies, and negative iodine uptake of the anterior neck on RxWBS were excluded. Serum Tg was checked twice, that is, 7 days after (post-ablation Tg) and on the day of RAI therapy (pre-ablation Tg). Ratio of pre-ablation Tg to post-ablation Tg (Tg ratio) was used to assess changes in serum Tg levels after RAI therapy. Patients were classified into two groups according to the presence of midline uptake above the thyroidectomy bed on RxWBS (negative (group 1) or positive (group 2) midline uptake). Variables were subjected to analysis to identify differences between the two groups. Two hundred and fifty patients were enrolled in this study; 101 in group 1 and 149 in group 2. Based on univariate analysis, post-ablation Tg (8.12 ± 11.05 vs. 34.12 ± 54.31; P < 0.001) and Tg ratio (7.81 ± 8.98 vs. 20.01 ± 19.84; P < 0.001) were significantly higher in group 2. On the other hand, gender, tumor (T) stage, lymph node (N) stage, size, multiplicity or bilaterality of primary tumor, dose of 131I, serum TgAb and thyroid-stimulating hormone (TSH) level (before or after RAI therapy) were not significantly different in the two groups. Variables with P values of < 0.25 by univariate analysis were subjected to multivariate analysis, which showed post-ablation Tg (OR 1.060, 95 % CI = 1.028–1.092; P < 0.001) and Tg ratio (OR 1.059, 95 % CI

    2015-01-01

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

    A thyroid screening program for individuals who had irradiation to the head and neck areas was started at Roswell Park Memorial Institute in February 1977 and by June 1979, 1,071 patients were seen in the clinic. Three hundred and ninety-six patients were found to have palpable abnormalities of the thyroid, and following pretreatment evaluation, suppressive therapy with triiodothyronine (T3) (50 μg/day) or DT (desiccated thyroid) (120 mg/day) was administered in a double-blind fashion. Two hundred fifty patients with nodular disease completed 6 mo of treatment and are analyzed in this paper. Pretreatment thyroid function tests showed that two patients had hypothyroidism with a high thyroid-stimulating hormone (TSH) and a low thyroxine level. A high incidence of thyroid autoantibodies was also noted and surgical findings confirmed a high incidence of chronic thyroiditis. Complete disappearance of the nodules was seen in 29% of the patients, and in addition, 38% of the patients were seen to have significant shrinkage of the nodules, indicating that radiation-associated thyroid nodules were as sensitive to the thyroactive agents as nonirradiated nodular thyroid disease. There was little difference in the response rate between T3 and DT. Both agents suppressed circulating TSH levels to an unmeasurable level in 76% of the patients. There was no correlation between scan findings and response rates. Thyroid carcinoma was found in 19% of the patients who underwent surgery; although all were well-differentiated carcinomas, two-thirds of the patients already had evidence of dissemination and/or invasion suggesting the aggressive nature of postirradiation thyroid carcinoma.

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

    The 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 131 I 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 [es

    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.)

    Studies have showed that lead was associated with human health. However, the effects of lead on thyroid functions are inconsistent, and studies based on Chinese population are fragmentary. To evaluate the correlation between lead and thyroid functions of Chinese with different thyroid diseases, we conducted a hospital-based study. Ninety-six papillary thyroid carcinoma (PTC), 10 nodular goiter (NG), and 7 thyroid adenoma (TA) patients were recruited from the First Affiliated Hospital of Wenzhou Medical University, China. Serum triiodothyronine (T3), free triiodothyronine (FT3), free thyroxin (FT4), and thyroid stimulating hormone (TSH) were evaluated with chemiluminescent microparticle immunoassay. Serum lead was assessed with ICP-MASS. Partial correlation was used to explore the correlations of serum lead and thyroid diseases. Compared to PTC, the level of lead was significantly higher in TA, and lower in NG (p lead was negatively correlated with TSH (r s  =  - 0.27, p lead at quartile4 (r s  = 0.61, p lead and FT3 or FT4 in any group. The results suggested that lead might have different etiological roles in these three thyroid diseases.

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

    Objectives: To explore the ultrasonic findings of metastatic thyroid carcinoma and to evaluate the diagnostic value of the ultrasonic imaging for patients with metastatic thyroid neoplasm. Methods: The ultrasonic imaging characteristics of ten patients who were diagnosed with metastatic thyroid carcinoma were retrospectively analyzed. In all the cases, fine-needle aspiration cytology (FNAC) of the thyroid was performed during the clinical diagnosis. Results: The ultrasonic images of the ten patients fell into four types: multiple nodules in the thyroid, single nodule in the thyroid, diffuse calcification and heterogeneous echo. Seven cases showed speckled calcific foci. Abnormal blood flow signal was found in 9 cases. Conclusion: The ultrasonic findings of metastatic carcinoma in the thyroid gland are various and non-specific. Color Doppler ultrasound may provide ample evidence. The diagnosis depends on FNAC.

    The question of thyroid neoplasia following high-dose radiation treatment to the neck and mediastinum for malignant neoplasms such as Hodgkin's lymphoma in children and young adults has been raised recently. Five patients, 19 to 39 years old, were operated on for thyroid neoplasms that developed following cervical and mediastinal radiation therapy for Hodgkin's lymphoma. Three patients had papillary carcinomas and two had follicular adenomas. The latency period between radiation exposure and the diagnosis of thyroid neoplasm ranged from eight to 16 years. This limited series provided strong support for the recommendation that children and young adults who are to receive high-dose radiation therapy to the head, neck, and mediastinum should receive suppressive doses of thyroxine prior to radiation therapy in order to suppress thyrotropin (thyroid-stimulating hormone) and then be maintained on a regimen of suppression permanently

    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.

  14. Acute paraparesis as presentation of an occult follicular thyroid carcinoma: A case report

    Directory of Open Access Journals (Sweden)

    José Miguel Baião

    Full Text Available Introduction: Follicular thyroid carcinoma is the second most frequent type of well differentiated thyroid tumours. It is usually confined to the thyroid gland, however it can metastasize in a later stage of the disease. Signs and symptoms associated with bone metastasis are rare as first clinical manifestations. Case report: An 84-year-old female complained with acute paraparesis. Magnetic resonance imaging revealed an extensive intraosseous infiltrating lesion compatible with a bone metastasis from an occult tumour. Biopsy samples were compatible with bone metastasis from a follicular thyroid carcinoma. The patient was submitted to total thyroidectomy followed by iodine ablative therapy. Discussion: Follicular thyroid carcinoma presentation with symptoms related to bone metastasis is rare. Patients with bone lesions, such as pathological fractures or compressive symptoms should be studied since they may have clinically unapparent lesions from an unknown tumour. Patients with FTC should be submitted to total thyroidectomy. Bone lesions may be addressed to improve quality of life however this decision depends on disease extent. Conclusion: Acute paraparesis is a rare form of presentation of thyroid carcinoma. These neoplasms must be taken into account when investigating metastasis to the bone from unknown neoplasms.

    A 51-year-old woman presented with a large goiter and on pathologic examination was found to have both Hashimoto's thyroiditis and medullary carcinoma of the thyroid. To our knowledge, this is the first well-documented case of the coexistence of these two entities in the same patient in the English literature. The association of Hashimoto's disease and carcinoma of the thyroid is reviewed and its relevance discussed.

    Incidence rate of differentiated thyroid carcinoma in teenager is not high. It has some different characteristics compared to adult differentiated thyroid carcinoma. Such as larger tumor at diagnosis; greater prevalence of neck lymph node and distant metastases at diagnosis; more sodium-iodide symporter expression; high recurrence rate but higher overall survival rate. 131 I administration to remove residual thyroid tissue and treat metastases is still one of the important approaches after surgery.

    Full Text Available Background: Familial nonmedullary thyroid carcinoma (FNMTC is a variant of nonmedullary thyroid carcinoma(NMTC with particular clinicopathologic features. In recent years, a number of studies have shown that FNMTC is more invasive than sporadic NMTC(SNMTC. The purpose of this study was to explore the differences in clinicopathologic features of FNMTC between different types of families and to determine in which of these families more invasive FNMTC occurred. Methods: We retrospectively reviewed all patients with thyroid carcinoma admitted to Peking Union Medical College Hospital from January 2009 to July 2013 in the database. Of all 2000 cases, 55 met the inclusive criteria for FNMTC and were studied. There are two different grouping methods. The first is that all samples were allocated to families with three or more first-degree relatives affected (FNMTC-3 group and families with only two affected first-degree relatives (FNMTC-2 group. The second is that all patients were divided into families with three or more affected first-degree relatives over two generations (FNMTC-3-2 group and the other families. We compared the clinicopathologic features such as sex, age, tumor size, multifocality, location, complications by thyroiditis, complications by benign thyroid nodules, surgical procedure, capsule invasion, histological type, lymph node metastases, tumor node metastasis stage, and BRAF mutation between FNMTC-2 group and FNMTC-3 group. We also made the same comparison between FNMTC-3-2 group and other families. Results: No pronounced differences in clinicopathological features were present between FNMTC-2 group and FNMTC-3 group. The proportion of FNMTC-3-2 group aged <45 years was significantly higher than that in the other families (58.8% vs. 26.3%, P = 0.021. A similar difference was found in the proportion of lymph node metastasis (64.7% vs. 34.2%, P = 0.035. Conclusions: FNMTC-3-2 is more invasive than the other families. Early screening

    1995-01-01

    A comparison between diagnostic and post therapeutic radioiodine imaging methods utilized in detection of thyroid metastases in 34 patients with well differentiated thyroid cancer was performed. The study revealed that the differences in detection on neck activity only between the two methods for papillary and follicular thyroid cancer were 35% and 27% respectively. While the overall detection percentages in both papillary and follicular thyroid cancers cases were 23% in diagnostic and 76% in post therapy scintigrams and the detection difference between the methods was 53% when all lesions throughout the body were seen on scintigram for only follicular thyroid cancer cases were counted, the detection percentage was increased up to 109%. It is clear that post therapeutic scans visualize an additional site activity not shown in diagnostic scans. There fore, post therapeutic imaging method is far superior to diagnostic imaging method and highly sensitive in visualization of thyroid metastases. On the other hand, this research also achieves many scientific and financial benefits. Therefore. This method should be adopted in management and follow up of well differentiated malignancies. 2 figs., 2 tabs

    To evaluate if a supervised exercise training program improves the quality of life (QoL) of differentiated thyroid carcinoma (DTC) patients on TSH-suppressive therapy with levothyroxine (L-T4). Initially, a cross-sectional study was performed to compare the QoL and the health-related quality of life (HRQoL) between subclinical hyperthyroidism (SCH) patients (n = 33) and euthyroid subjects (EU; n = 49). In the prospective phase of the study, SCH patients were randomized in a non-blinded fashion to either participate (SCH-Tr = trained patients; n = 16) or not (SCH-Sed = untrained patients; n = 17) in a supervised exercise training program. The exercise program consisted of 60 minutes of aerobic and stretching exercises, twice a week, during twelve weeks. The QoL was assessed by the application of the WHOQOL-Bref, and the SF-36 was used to assess the HRQoL. SCH patients had statistically lower scores than EU on the "physical" domain of WHOQOL-Bref, besides "physical function", "role-physical", "bodily pain", "general health", "vitality", "role-emotional", and "mental-health" domains of SF-36. After three months, SCH-Tr patients showed improvement in the "physical" and "psychological" domains of WHOQOL-Bref (p after 3-months of an exercise training program. Exercise seems to play an important role in the follow-up of DTC patients, since it seems to minimize the adverse effects of the treatment on QoL and HRQoL.

    The (131)I-iodide ((131)I) whole-body scan, for thyroid carcinoma is at times difficult to interpret. In a diagnostic whole body (131)I scan of a patient with follicular carcinoma, a posterior skull lesion was partially hidden by overlapping facial structures. On lateral head view, the abnormality was clearly evident. SPECT/CT and MRI showed the lesion originated in the occipital bone and had enlarged into the posterior fossa. The mass was surgically removed and the patient received (131)I therapy for residual tissue. The study demonstrates a pitfall in the reading of two dimensional radioiodine images which can be overcome by SPECT or lateral imaging. Copyright © 2013 Elsevier España, S.L. and SEMNIM.

    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.

    Medullary thyroid carcinoma (MTC) comprises approximately 4% of all malignant thyroid neoplasms. Although the majority of patients have a good prognosis, a subgroup of patients develops progressive disease and requires systemic therapy. Here, we focused on the current MTC therapeutic approaches and discussed the advantages and disadvantages of molecular targeted therapies. Targeted molecular therapies that inhibit RET and other tyrosine kinase receptors involved in angiogenesis have been shown to improve progression-free survival in patients with advanced MTC. Two drugs, vandetanib and cabozantinib, have been approved for the treatment of progressive or symptomatic MTC, and several others have exhibited variable efficacy. No tyrosine kinase inhibitor has been shown to improve survival. Although no definitive recommendation can currently be made, cumulative data indicate that knowledge of the tumor mutational profile may facilitate improvements in targeted therapy for MTC. Tyrosine kinase inhibitors are effective therapeutic agents for the treatment of progressive MTC. Nevertheless, it is not clear who will benefit the most from therapy, and the decision regarding when and how to initiate the treatment should be made based on the patient's medical history and tumor behavior. Hopefully, in the near future, molecular profiling of MTC can be used to determine the most effective molecular therapeutic target.

    Papillary thyroid carcinoma has a favorable outcome in children. Recent experience with young children cases with early recurrences, after the total thyroidectomy and excision of palpable lymph nodes, in contrast to usual course of disease in adolescent cases, prompted us to review our experience on papillary carcinoma surgery. Sixteen children who underwent surgery for papillary carcinoma between 1997 and 2010 were included. The charts and surgery notes were evaluated retrospectively and age, sex, complaints and physical findings at presentation, past medical history, results of laboratory tests, imaging findings, aspiration biopsy, extent of disease, details of surgery, complications and postoperative course were noted. Male to female ratio was 3:1. The mean age was 10.9 years (range, 5-16). The presenting symptom was palpable swelling in the neck (n = 12) or asymptomatic nodule was detected incidentally (n = 4). Physical examination findings were palpable nodule (n = 7), lymphadenopathy (n = 6) or both (n = 4). Thyroid ultrasound (US) revealed nodule (n = 9), heterogenisity of the parenchyma and enlargement of thyroid (n = 9), and microcalcifications (n = 5). Fine-needle aspiration biopsy was performed in 12 patients and was suggestive for malignancy in most cases (91%). Pulmonary metastasis was detected at presentation in two patients and appeared after thyroidectomy in one patient. Complementary thyroidectomy was performed in nine patients because the total thyroidectomy with or without cervical lymph node dissection was the treatment of choice (n = 15). Iodine scan was performed 4 weeks later following thyroidectomy. Radioactive iodine ablation (RIA) therapy was given to 11 patients who had residual or recurrent disease. Postoperative complications were permanent hypoparathyroidism (n = 4), recurrent laryngeal nerve injury (n = 3), lymphorea (n = 1) and Horner's syndrome (n = 1). Total thyroidectomy and excision of affected lymph nodes is the current mode of

    Brain metastases from differentiated thyroid carcinoma are extremely rare and carry a poor prognosis. We describe here clinical details of 7 cases of brain metastases from papillary thyroid carcinoma. Of 153 patients with metastases from differentiated thyroid carcinoma (papillary in 123, follicular in 30) treated at our institution between 1981 and 1999, 7 patients (4.6%) had brain metastases. Histologically, the primary tumor was papillary carcinoma in all 7 cases. Four were males and 3 were females. The median age at first diagnosis of distant metastases was 63 yr (range, 47-76 yr). Of these patients, one had brain metastases only and six and metastases to the lungs as well. Five of these patients were treated with 131 I. Three of these 5 patients had marked uptake in the metastases ( 131 I positive) on post-therapy 131 I scans and another 2 patients had no significant activity ( 131 I negative) in both pulmonary and brain metastatic lesions. One of 3 patients with 131 I positive lesions had intense activity in the brain tumor, but no uptake in multiple pulmonary metastatic tumors. In a patient with 131 I positive brain metastases, the tumors progressed rapidly after 131 I therapy. In another one patient, acute hemorrhage of the tumor occurred four days after 131 I therapy, requiring surgical removal. Loner case of 131 I negative 2 patients was treated with radiosurgery (γ-knife) and complete reduction in tumor volume was observed. On the other hand, one of 2 patients receiving no 131 I therapy had radiosurgery (x-knife) and remaining one received conventional external radiation and chemotherapy for small solitary brain and pulmonary metastatic tumors. These therapeutic interventions were useful in both cases. The mean length of survival after the development of brain metastases in the five patients who died of the disease was 30 months. One patient treated with x-knife has been alive at 21 months and another one who has 131 I uptake in the brain tumor without

    To evaluate the reliability of the procedure T1-201 total body scintigraphy was performed in 294 patients (449 studies) after total thyroidectomy for thyroid carcinoma. Results were correlated with I-131-scintigraphy and tumor-marker levels (Tgb or Calcitonin/CEA). T1-201 total body scintigraphy was negative in 196 patients with no evidence of disease. T1-201-scintigraphy correctly detected tumor localizations in 24 of 30 patients with I-131-positive metastases. In 28 patients T2-201 total body scintigraphy revealed metastases which did not concentrate I-131. Histology/cytology confirmed thyroid carcinoma metastases in 16 patients and other pathology in 5 cases. 9 of 18 patients with medullary thyroid carcinoma (I-131-negative) had elevated Calcitonin/CEA-levels. The T1-201 scintigram was positive in 8 of these patients. Comparison of T1-201, I-131 and tumor markers showed that only combined use of these parameters provide complete reliability. The authors conclude that T1-201 total body scintigraphy is useful in follow up of thyroid carcinoma, especially when a discrepancy of the other parameters exists and particularly in medullary carcinoma. In long term follow up of patients who are unsuspected of disease after successful therapy for thyroid carcinoma one can rely on T1-201 total body scintigraphy in combination with tumor marker assays

    Thyroid-associated antigens, such as calcitonin, thyroglobulin and carcinoembryonic antigen(CEA), can be demonstrated by immuno-histochemical detection. The main purpose of this study is to investigate the diagnosis, especially in regard to proving or excluding the thyroid origin of metastasis. A total of 47 cases of the thyroid specimen including 5 colonic and 5 ovarian cancer were studied by immunoperoxidase stain for the distribution and intensity of the calcitonin, thyroglobulin, and CEA. The following results are obtained. 1. The calcitonin reveals diffuse intracellular positivity of only medullary carcinoma, all others are negative. 2. The thyroglobulin show 100% positivity to thyroid adenoma, follicular carcinoma and papillary carcinoma although their intensity and distribution differed in each tumor. 3. The CEA reveals strong positivity of colonic carcinoma and ovarian carcinoma, intracytoplasmic and luminal, as well as moderate positive reaction of follicular carcinoma and papillary carcinoma of throid. In summary, the calcitonin is best tumor marker for medullary carcinoma, where as the thyroglobulin is best for follicullar and paillary carcinoma. The CEA shows variable stain property, but it has a good correlation to diagnosis of colonic carcinoma and ovarian carcinoma. (Author)

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

    Most prognostic studies in differentiated carcinoma have included a high number of papillary carcinomas and few follicular carcinomas, and not all of their conclusions therefore apply to the latter. To analyze the prognostic factors of follicular thyroid carcinoma. Patients with histological diagnosis of follicular carcinoma who had undergone potentially curative surgery, had no disseminated disease at diagnosis, and had been followed up for at least 5 years. Tumor recurrence was defined as: 1) tumor lesions with cytological analysis suggesting malignancy and/or 2) patients with total thyroidectomy with thyroglobulin levels >2 ng/mL. Clinical, therapeutic, and histological parameters were analyzed to assess prognostic factors. Recurrence was found in 25 (38%) of the 66 study patients during a follow-up period of 99 ± 38 months. Most patients with recurrence (n=20) had increased Tg levels without anatomical location, and were initially treated with radioactive I131. In the remaining 5 cases, surgical excision of the lesion was performed, and three patients required surgery during the follow-up period. Two patients died due to the disease (3%), and two other patients (3%) currently have distant metastases. Mean disease-free interval was 154 ± 14 months, and rates of disease-free patients at 5, 10, 15, and 20 years were 71, 58, 58, and 58% respectively. Clinical factors influencing recurrence included 1) age (p=0.0035); 2) sex (p=0.0114); and 3) cervical pain (p=0.0026). Histological/surgical factors associated with recurrence included 1) infiltration into neighboring structures (p=0.0000); 2) type of carcinoma (p=0.0000); 3) size (p=0.0162); 4) vascular invasion (p=0.0085); and 5) adenopathies (p=0.046). In the multivariate study, cervical pain (p=0.018) and extrathyroid invasion (p=0.045) continued to be significant factors. In follicular carcinoma, rates of disease-free patients are 71% at 5 years and 58% at 10 years, and the main predictive factors are presence

    Full Text Available 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.

    Full Text Available Metastatic tumors are of great significance since few cases may represent the only symptom of an undiscovered underlying malignancy. Metastatic tumors rarely metastasize to the oral region despite the fact that many common primary neoplasms frequently metastasize to bone. The true incidence of metastatic tumors in the bones of the jaw is unknown, as jaws are not always included in radiographic skeletal surveys for metastasis. Sometimes oral metastasis may be the first evidence of metastasis from its primary site. A case of metastatic follicular thyroid carcinoma to the mandible is presented here, along with the discussion of clinical and histological features. The present case not only emphasizes the importance of considering metastasis in the differential diagnosis of a radiolucent lesion in the mandible, but also emphasizes in the improvement of the overall survival rate and treatment results by an early detection of metastatic disease.

    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.

    A patient with progressively worsening thyrotoxicosis, refractory to medical therapy, is described. Repeated measurements of thyroidal RAI uptake over a 13 month period were low consistently and could not be explained by iodine ingestion, thyroiditis, or administration of exogenous thyroid hormone. An I-131 scan ultimately revealed striking activity at the base of the skull, reflecting ectopic excessive production of thyroid hormone by a solitary functioning metastatic thyroid carcinoma. The thyrotoxic state resolved after large doses of therapeutic I-131. Typical features of this rare cause of hyperthyroidism are discussed

    2016-08-01

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

    This study was performed to clarify factors that might influence short-term side effects occurring within 96 hours after administration of 131 I for patients with thyroid carcinoma. In 71 patients with differentiated thyroid carcinoma, short-term side effects including gastrointestinal complaints, salivary gland swelling with pain, change in taste and headache were retrospectively analyzed. All patients were given domperidone for prevention of gastrointestinal complaints and advised to consume sour foods to promote discharge of radioiodine from the salivary glands. Selected factors possibly affecting the incidence of side effects were dose per body weight, thyroid stimulating hormone (TSH), effective half-life of 131 I, sex, age, 131 I accumulation into the stomach and salivary glands, and edema prior to radioiodine administration. The factors were evaluated by multivariate analyses. Incidence of gastrointestinal complaints, salivary gland swelling with pain, change in taste and headache was 65.2%, 50.0%, 9.8% and 4.4%, respectively. In gastrointestinal complaints, the incidence of appetite loss, nausea and vomiting was 60.9%, 40.2% and 7.6%, respectively. The gastrointestinal complaints increased significantly in the patients dosed above 55.5 MBq/kg and with TSH elevation. For salivary gland swelling with pain, female patients displayed a significantly higher incidence than males. No statistically significant factors were detected for change in taste or headache. Significant factors influencing short-term side effects were dose per body weight and TSH values for gastrointestinal complaints, and female sex for salivary gland swelling with pain. Our preliminary experience suggests that the most frequent gastrointestinal complaints can be prevented with ramosetron. (author)

    Thyroid disorders; hyper/hypothyroidism/thyroiditis/neoplasms are widely prevalent endocrine disorders. Oral manifestations of hyperthyroidism are increased susceptibility to caries, periodontal disease, maxillary/mandibular osteoporosis, premature shedding of deciduous teeth and early eruption of permanent teeth, sjogren and burning mouth syndromes. Undiagnosed/untreated hyperthyroidism often precipitates as 'Thyroid storm' during a stressful episode of surgical intervention/trauma. Hypothyroidism shows macroglossia, micrognathia, dysgeusia, thick lips, delayed eruption of teeth, poor periodontal health, enamel hypoplasia, anterior open bite, delayed wound healing and subnormal growth of jaws. Its congenital variant has underdeveloped mandible/overdeveloped maxilla, shortening of skull base and flaring of nostrils. Stomatodynia predominates in subacute thyroiditis. Radioactive iodine ( 131 I) is a common mode of therapy for thyrotoxicosis and carcinomas; where its beta radiations cause destruction of thyroid follicles. Since all forms of iodine are actively taken up by the salivary glands, salivary dysfunction is a consequent of 131 I therapy. It usually presents as xerostomia, mucositis, stomatitis, glossitis and dysguesia. Though reversible and dose-dependent to some extent, damage to bone marrow and gonads are also reported. It follows that thyroid disorders and its therapy with radio iodine show wide ranging side effects: both dental and general. In this context, this paper explains a novel method to evaluate these changes through salivary biochemistry, dental indices and periodontal markers. (author)

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

    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. 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. 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

    Anaplastic thyroid cancer is a rare and fatal malignancy, associated with significant local tumour and often treatment related morbidity. We report our experience in treating this cancer over a 20-year period. A retrospective review of prospectively collected data from a single Australian Institution (Alfred Health Radiation Oncology) was carried out on patients referred with anaplastic thyroid carcinoma between 1992 and 2013. Thirty patients (17 females and 13 males) were identified with a median age at presentation of 72 years. At presentation, six (20%), 14 (47%) and 10 (33%) patients had stage IVA, IVB and IVC disease respectively. Thirteen patients underwent radical surgical resection with five having microscopic residual (R1) and eight having macroscopic residual (R2) disease. Twenty-eight patients were offered radiotherapy with 27 proceeding with treatment. Of those who received radiotherapy, three, six and 18 were treated with adjuvant, definitive and palliative intent respectively. Six patients had concomitant chemotherapy of which three received trimodality therapy. Only one patient experienced a grade 3 toxicity (oesophagitis). Median survival was 5.3 months and at last follow-up or time of death, 19 of 27 (70.4%) maintained loco-regional control. All patients who had R1 surgical resections and radiotherapy had loco-regional control. Seven of nine (77.8%) and 12 of 18 (66.7%) achieved loco-regional control after receiving definitive or palliative radiotherapy, respectively. Our study suggests that radiotherapy with or without surgery or chemotherapy is well-tolerated and results in durable loco-regional control in a high proportion of patients with anaplastic thyroid carcinoma.

  9. Diffuse sclerosing variant of thyroid papillary carcinoma: Diagnostic challenges occur with Hashimoto's thyroiditis

    2013-06-01

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

    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.

  12. Effect of the micronutrient iodine in thyroid carcinoma angiogenesis.

    Science.gov (United States)

    Daniell, Kayla; Nucera, Carmelo

    2016-12-20

    Iodide is a micronutrient essential for thyroid hormone production. The uptake and metabolism of iodide by thyrocytes is crucial to proper thyroid function. Iodide ions are drawn into the thyroid follicular cell via the sodium-iodide symporter (NIS) in the cell membrane and become integrated into tyrosyl residues to ultimately form thyroid hormones. We sought to learn how an abnormal concentration of iodide within thyrocyte can have significant effects on the thyroid, specifically the surrounding vascular network. Insufficient levels of iodide can lead to increased expression or activity of several pathways, including vascular endothelial growth factor (VEGF). The VEGF protein fuel vessel growth (angiogenesis) and therefore enhances the nutrients available to surrounding cells. Alternatively, normal/surplus iodide levels can have inhibitory effects on angiogenesis. Varying levels of iodide in the thyroid can influence thyroid carcinoma cell proliferation and angiogenesis via regulation of the hypoxia inducible factor-1 (HIF-1) and VEGF-dependent pathway. We have reviewed a number of studies to investigate how the effect of iodide on angiogenic and oxidative stress regulation can affect the viability of thyroid carcinoma cells. The various studies outlined give key insights to the role of iodide in thyroid follicles function and vascular growth, generally highlighting that insufficient levels of iodide stimulate pathways resulting in vascular growth, and viceversa normal/surplus iodide levels inhibit such pathways. Intriguingly, TSH and iodine levels differentially regulate the expression levels of angiogenic factors. All cells, including carcinoma cells, increase uptake of blood nutrients, meaning the vascular profile is influential to tumor growth and progression. Importantly, variation in the iodine concentrations also influence BRAF V600E -mediated oncogenic activity and might deregulate tumor proliferation. Although the mechanisms are not well eluted, iodine

    The multitargeted tyrosine kinase inhibitor sunitinib is known to induce thyroid dysfunction in a substantial proportion of patients treated for advanced renal-cell carcinoma or gastrointestinal stromal tumors. Although sunitinib-induced hypothyroidism seems to be reversible in the majority of patients, some patients develop irreversible thyroid damage resulting in long-lasting thyroid hormone replacement therapy. We report on two cancer patients with a preexisting nodular thyroid gland, who developed thyroid dysfunction and showed marked shrinkage of the thyroid during treatment with the tyrosine kinase inhibitor, necessitating permanent thyroid hormone replacement therapy even after discontinuation of the anticancer agent. Sunitinib treatment in patients with a nodular thyroid can induce a significant decrease in the volume of the enlarged endocrine gland, associated with abnormal thyroid function tests leading to clinical hypothyroidism. The exact pathophysiology remains unknown but we discuss several possible mechanisms of sunitinib-induced thyroid shrinkage. Morphological changes of the thyroid gland can be associated with the well-described adverse biochemical effects of treatment with sunitinib and can be a potential marker of the irreversible organ damage.

    The optimal surveillance strategy to screen for thyroid carcinoma childhood cancer survivors (CCS) at increased risk is still debated. In our clinical practice, beside neck palpation we routinely perform thyroid ultrasound (US). Here we describe the results obtained using this approach. We considered all CCS referred to our long term clinic from November 2001 to September 2014. One hundred and ninety-seven patients who had received radiation therapy involving the thyroid gland underwent US surveillance. Thyroid US started 5 years after radiotherapy and repeated every 3 years, if negative. Among 197 CCS previously irradiated to the thyroid gland, 74 patients (37.5%) developed thyroid nodules, and fine-needle aspiration was performed in 35. In 11 patients the cytological examination was suspicious or diagnostic for malignancy (TIR 4/5), whereas a follicular lesion was diagnosed in nine. Patients with TIR 4/5 cytology were operated and in all cases thyroid cancer diagnosis was confirmed. The nine patients with TIR 3 cytology also underwent surgery and a carcinoma was diagnosed in three of them. Prevalence of thyroid cancer was 7.1%. Tumour size ranged between 4 and 25 mm, but six (43%) were classified T3 because of extra-thyroidal extension. Six patients had nodal metastases; in eight patients the tumour was multifocal. At the time of the study all patients are disease free, without evidence of surgery complications. Applying our US surveillance protocol, the prevalence of radiation-induced thyroid cancer is high. Histological features of the thyroid cancers diagnosed in our cohort suggest that most of them were clinically relevant tumours. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available The thyroid gland is a rare site of clinically detectable tumor metastasis and kidneys are frequently the site of the parent malignancy. In the present review on thyroid metastases from renal cell carcinoma, cases were searched on PubMed by entering the strings: “renal carcinoma [or“hypernephroma”] AND thyroid metastasis/metastases”. Thus, we retrieved a total of 111 cases that were published between 1964 and 2007, a total that became 113 by adding two patients observed by us. The female to male ratio was 1.35:1. The primary renal cancer was almost always unilateral (90% (with no significant side preference and only rarely bilateral (9% in men, 4% in women, whereas bilaterality of thyroid metastases was relatively more frequent (28%. Thyroid metastasis from renal cancer was commonly single with a unique node that appears solid and hypoechoic at ultrasonography, approximately 9 years after nephrectomy. Concordance of lateralization was insignificantly greater for the right kidney/right thyroid lobe pattern (54% than for the left kidney/left thyroid lobe pattern (40%, regardless of gender. Finally, survival was longer for women. Thyroid metastases, even if rare in the clinical practice, must be considered in the differential diagnosis of a thyroid nodule, particularly in patients who have a history of malignancies.

    Extra thyroidal extension (ETE) of thyroid papillary carcinoma (PAC) is known as a risk factor of poor prognosis. The American Thyroid Association (ATA) Guideline recommends total thyroidectomy (TT) with radioiodine ablation for patients of PACs with ETE and we have been following this strategy for cases of PACs with ETE. In this paper, we retrospectively examined the patients of PACs with ETE in terms of the following two issues: Does 131 I total body scan ( 131 I-TBS) after TT enable us to detect subclinical distant metastases of PACs? and Can 131 I ablation eliminate microscopic remnants of PACs after TT? The subjects consisted of 68 patients who had PACs with ETE and underwent 131 I-TBS and/or 131 I ablation after TT in our hospital in the past 20 years. Tumor, nodes and metastasis (TNM) classifications of the patients were pT3:pT4=12:56, pN0:pN1a:pN1b=13:15:40, M0:M1=62:6. Twenty-two cases underwent only 131 I-TBS and 46 cases underwent 131 I-ablation. Fourteen cases diagnosed as M0 preoperatively had distant focus detected using 131 I-TBS. Including M1 cases, 20 out of 68 cases (29%) turned out to have clinical or subclinical distant lesions in our study. 131 I ablation eliminated thyroid bed in 18 out of 22 cases, and distant foci in 5 out of 13 cases. However, the distant lesions which had been apparent before operation (M1 cases) did not reach complete response (CR) by 131 I ablation. In 22 out of those 23 cases successfully treated with the ablation, serum-thyroglobulin level was almost undetected after therapy. The overall 10-year survival rate was 82% and the cause-specific survival rate was 91%. (author)

    Background: Recent reports indicated that incidence of thyroid carcinoma is increasing throughout the worldwide. The aim of our study was to determine a possible relationship between Forkhead box E1 (FOXE1) gene variants and histopathological features of papillary thyroid carcinoma. Methods: FOXE1 gene variations; rs894673, rs1867277 and rs3758249 were analyzed in 57 Papillary thyroid carcinoma patients and 51 age matched healthy control subjects. Restriction fragment length polymorphism (RFLP) technique was used to specifically detect the variations. Results: There was a significant difference in the distribution of rs894673 genotypes in Papillary thyroid carcinoma cases (P=0.01). AA genotype presence of rs1867277 was more significantly associated with several histopathological parameters such as focal and diffuse capsular invasion, lymphatic invasion, P3 with P4 tumor grade and surgical margins. AA genotype presence in rs1867277 variation was significantly associated with the classical variant which is subtype of papillary thyroid carcinoma. Furthermore, the presence of the allel A was found to be related with lymph node invasion risk by 2.46 fold, capsular invasion risk by 2.97 fold, and pT3 with pT4 pathological stage risk by 4.13 fold and the presence of allele A in rs1867277 was significantly associated with classic variants. The presence of allele A in rs1867277 was more significantly associated with several histopathological parameters in classic variant in papillary thyroid carcinoma cases such as, the presence of the A allele was found relationship with lymph node invasion risk by 2.0 fold, capsular invasion risk by 2.39 fold , and pT3 with pT4 pathological stage risk by 3.57 fold. In addition, AATT, AAAA and GATT haplotypes (rs1867277 and rs894673) were evaluated for association with papillary thyroid carcinoma cases. Our results indicate that the significant difference according to two-allele haplotype distribution between papillary thyroid carcinoma

    Undifferentiated thyroid carcinoma (UTC) lacks an effective treatment. Boron neutron capture therapy (BNCT) is based on the selective uptake of 10 B-boronated compounds by some tumours, followed by irradiation with an appropriate neutron beam. The radioactive boron originated ( 11 B) decays releasing 7 Li, gamma rays and alpha particles, and these latter will destroy the tumour. In order to explore the possibility of applying BNCT to UTC we have studied the biodistribution of BPA. Animal Model: To develop an animal model of undifferentiated thyroid carcinoma (UTC), which may be useful to study of BNCT. The UTC human cell line ARO was implanted into the back of the nude mice. We performed successive passages in mouse after tumor culturing in order to obtain an animal model similar to the human tumor. We studied the kinetics and the tumoral histology, the capability to induce metastasis, the biokinetics of in vitro growth, as well as cytogenetic and molecular aspects. Histological specimens of tumor showed extensive viability with high mitotic activity. At 117 days, the tumors reached a size of 1700 mm 3 and showed a central necrotic portion with a thin layer of viable cells presence of micro metastasis could be observed in the lung. The kinetics of growth both in vivo and in vitro showed that when the number of passages in mouse increases the growth rate decreases. The cytogenetic and molecular studies did not show differences between the original line and the sublines that could explain this phenotypic change. Moreover, the cytogenetic studies proved that the ARO cell line and its sublines showed a complex clonal karyotype including structural alterations with deletions and translocations involving chromosomes 5, 7, 8, 9p, 11p, 17q 19p, and 20q that were consistent with earlier reported data in UTC. In vivo BNCT studies: ARO cells were transplanted into the scapular region of NIH nude mice, and after 2 weeks BPA (350 or 600 mg/kg bw) was injected via i.p. The

    Anaplastic thyroid carcinoma (ATC) is a malignancy with one of the highest fatality rates. We reviewed our recent clinical experience with intensity modulated radiotherapy (IMRT) combined with surgery and chemotherapy for the management of ATC. 13 patients with ATC who were treated by IMRT in our institution between October 2008 and February 2011, have been analyzed. The target volume for IMRT was planned to include Gross tumor volume (GTV): primary tumor plus any N + disease (66 Gy/33 F/6.6 W), with elective irradiation of thyroid bed, bilateral level II through VI and mediastinal lymph nodes to the level of the carina (54-60 Gy). Seven patients received surgical intervention and eleven patients had chemotherapy. The median radiotherapy dose to GTV was 60 Gy/30 fractions/6 weeks. The median survival time of the 13 patients was 9 months. The direct causes of death were distant metastases (75%) and progression of the locoregional disease (25%). Ten patients were spared dyspnea and tracheostomy because their primary neck lesion did not progress. The results showed that IMRT combined by surgery and chemotherapy for ATC might be beneficial to improve locoregional control. Further new therapies are needed to control metastases

    A 33-year-old woman had been operated on for a tumor of the thyroid gland in December of 1976, and was admitted to Saku Central Hospital in April of 1983 because of pulmonary and ovarian metastases. She underwent surgical removal of the metastatic ovarian tumor and chemotherapy, but developed headaches in June of 1983. Computed tomography (CT) scan revealed a well-defined, homogeneously enhanced mass in the right occipital region. Angiography showed a homogeneous, well-defined tumor stain supplied by the right posterior cerebral artery, the posterior branch of the middle meningeal artery, and the meningeal branch of the occipital artery. The tumor was removed in July of 1983. It was situated in the right occipital lobe and was supplied by numerous small meningeal vessels. Histologically, it was composed of small, oval-shaped cells, some with mitotic figures, and giant cells, occasionally forming a follicular structure. Three months later, the headaches reappeared, and a recurrence of brain metastasis was demonstrated by CT. In October of 1983, the second metastatic brain tumor and the dural bed were removed and local radiation therapy was administered. In this case, meningioma-like features were demonstrated by CT scan and angiography, and these findings may be characteristic of brain metastasis of follicular carcinoma of the thyroid gland.

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

    Thyroid cancer is the most common endocrine malignancy. The epidemiology of thyroid cancer is variable, depending on the geographic location of the patient population. Well differentiated thyroid cancer (WTC), is responsive to high dose I-131 treatment, and is the most accepted form of therapy, even though the dose administered for ablation of residual thyroid tissue maybe controversial. At our centre, 75 patients of WTC, mean age 42.4 years, 22 males and 53 females (M:F 1:2.4), were treated with high dose oral I-131 therapy with a Total Mean Dose (TMD) of 263.6 mCi, 4 - 6 weeks post thyroidectomy. They were followed up over a period of 6 years. Twenty ( 26.7%) patients had follicular cancer (FC), 47 (62.7%) papillary cancer (PC) and 8 (10.7%) were mixed (MC), on histopathology, at presentation. 38 (50.7%) patients had only residual thyroid tissue (RTT) on I-131 whole body bone scan (WBS) and 37 (49.3%) presented with metastatic disease (MD) at the time of therapy. Of the 37 patients with MD, 21 (56.8%) had metastases to the lymph nodes, 6 (16.2%) to the lungs, 4 (10.8%) to bone, 3 (8.1%) to bone and lung, and 4 (10.8%) to lung plus lymph nodes. Twenty-three patients (7 FC , 13 - PC and 3 MC; 6 RTT, 17 - MD) , received more than one dose of I-131 with a TMD of 422.7 mCi (Range 88 1590 mCi ). 52 patients (13 FC, 34 PC, 5 MC; 20 MD and 32 RTT) received a single TMD of 104.4 (Range 39.5 219 mCi). On follow-up, 3 patients of FC with MD (2 lung metastasis and 1 with extensive lymph node metastasis), died within 3 months 2 years of therapy. 3 patients of MD (2 FC, 1-MC; 2 bone metastasis and 1 bone with lung metastasis) died after 5 .5 years, Of the 6 patients who died, 5 were FC and only 1 was MC. 2 patients with MD to lungs and bone had received a single dose and were lost to follow up. All patients with PC and FC with only RTT, were surviving at the end of 5 years. None of the patients with MD to lymph nodes died at the end of 5 years, either receiving single or

    This is the second report of the Inquiry in the title performed in June, 2010, following the first investigation in January, 2009, to 422 hospitals being or having been capable of internal 131 I treatment (RI therapy) of inpatients with thyroid cancers in the ward or of outpatients with Basedow disease. The questionnaire asked about the present working situation and future planning of the ward, present situation of the therapy, evaluation and demand concerning the medicare reword of the therapy revised in 2010, waiting period of time for the therapy, scales of drainage equipment and of legal report of 131 I. Reply was obtained from 55.2% of the facilities. Results were: the number of sickbed decreased from 188 (2002, from a reference) to 138 (2010) despite every 5% increase of 131I therapy number per year during the interval; actually used bed number tended to be saturated (36.5 to 87.7%, respectively); even in the short period from 2009 to 2010 (1.5 years), patients' wait time tended to prolong from 4.9 to 5.2 months; and recent revision of the reward was not always satisfactory for economy of medical facilities. It was concluded that prompt national measures to solve the actual situation above should be appropriately taken by increasing the bed and ward. (T.T.)

    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. 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. 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. 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.

    Definition of a strategy for the management of thyroid differenciated carcinoma in children. Retrospective cohort study from the Normandy area in France. Analysis of the medical records of 13 children and adolescents (age > 15 years), presenting with thyroid differenciated carcinoma in three Normandy French hospitals from 1994 to 2006, to determine the clinical features and treatment of the disease. X of the patients were male and y were female, with a mean age at presentation of 11 years. Most frequently symptom was solitary nodes in the thyroid gland (69%). Most frequent histological type was papillary cancer (92%). Size of tumor was > 4 cm in 23% of cases. Children had undergone surgery with total thyroidectomy, radio-iodine treatment and suppressive hormonotherapy. We observed 46% post surgery complications. All patients were alive and none developed a recurrence. Thyroid differenciated carcinoma in children and adolescents were more agressif with most frequently metastasis and recurrence than thyroid differenciated carcinoma of adults. Pronostic is good with 90% of survival at 20 years. We propose a coherent plan of treatment: 1. Thyroidectomy with cervical central lymph node dissection (group VI) completed bilateral selected head neck dissection compartments (groups IIa, III, IV) if macroscopic lymph node metastases in lateral cervical compartment. 2. Postoperative radioiodine is done in all tumor > T1N0 and completed with hormonotherapy.

    Sarcomas are rare tumors originating from soft tissue or bone. Diagnosis and treatment of sarcomas should be performed at specialized sarcoma centers, where patients are evaluated at a multidisciplinary tumor conference. We present a case where sarcoma was suspected from magnetic resonance imaging (MRI), but histology revealed a metastasis from thyroid carcinoma, although the patient had no previous history of thyroid malignancy and resection of the thyroid gland was without malignancy. Ultrasound-guided biopsy was possible due to cortical destruction and the multidisciplinary approach with re-evaluation of previous pathology and a thorough patient history enabled a final diagnosis

    Full Text Available This study sought to reveal the significance of IL-6 in papillary thyroid carcinoma by determining its circulating levels, tumoral protein, and mRNA expressions. As compared to the healthy individuals, serum IL-6 was significantly higher in patients with benign thyroid diseases and PTC. Further, its level was significantly higher in PTC patients as compared to patients with benign thyroid diseases. ROC curves also confirmed a good discriminatory efficacy of serum IL-6 between healthy individuals and patients with benign thyroid diseases and PTC. The circulating IL-6 was significantly associated with poor overall survival in PTC patients. IL-6 immunoreactivity was significantly high in PTC patients as compared to the benign thyroid disease patients. Significantly higher IL-6 mRNA expression was also observed in the primary tumour tissues of PTC patients than the adjacent normal tissues. The protein expression of IL-6 at both the circulating and tissue level correlated with disease aggressiveness in PTC patients. Moreover, a significant positive correlation was observed between the IL-6 protein and mRNA expression in the primary tumours of PTC patients. Finally in conclusion, IL-6 has an important role in thyroid cancer progression. Thus targeting IL-6 signalling can help in clinical management of thyroid carcinoma patients.

    Differentiated thyroid carcinoma staging is increasingly important due to the current trends to a less intensive therapy in low-risk patients. The TNM system is most widely used, but other systems based on follow-up of several patient cohorts have been developed. When these systems have been applied to other populations, results have been discordant. Our study evaluates the suitability of several differentiated thyroid carcinoma staging systems in a Spanish population. 729 patients with differentiated thyroid carcinoma and staging data available were enrolled. Mean follow-up time was 10.8 years. The TNM, EORTC, AMES, Clinical class, MACIS, Ohio, NTCTCS, and Spanish systems were applied to all histological types. The Kaplan-Meier survival curves for each system were analyzed, and compared using the proportion of explained variation (PEV). The demographic and clinical characteristics of our population were similar to those of other Spanish and international cohorts reported. The best systems were NTCTCS, with 74.7% PEV, and TNM (68.3%), followed by the Ohio, MACIS, EORTC, and AMES systems with minimal differences between them, while the least adequate were the Spanish (55.2%) and Clinical class (47.1%) systems. The NTCTCS staging system was found to be better than TNM in our population but, because of its simplicity and greater dissemination, the TNM appears to be recommended for staging of patients with differentiated thyroid carcinoma.

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

    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 131 I by the thymus in patients under 50 years of age is a potential cause of false-positive therapy scans.

    Full text: 99 Tc m (V)DMSA has been reported to be highly sensitive in the diagnosis of medullary thyroid cancer (MTC). Rhenium-188, a beta emitter, has potential for therapy of MTC. However, initial studies with 188 Re indicate high renal uptake which may interfere with potential therapeutic applications of this radiopharmaceutical. A modified radiolabelling method has been shown to reduced the renal uptake of 188 Re(V)DMSA in control animals. The aims of this study were to determine whether there is uptake of modified 188 Re(V)DMSA in nude mice injected with an MTC cell line and whether there is potential for MTC therapy. Two groups of mice were injected in the left flank (SC) with TT cell line, and in mice showing tumour growth a low-dose (400 kBq) of 188 Re(V)DMSA was injected via a tail vein 8 weeks later. Biodistribution was performed on several mice and several others were given 'therapy' injections (8 MBq) to determine whether tumour shrinkage could be objectively observed. Tracer uptake was highest in bone and kidneys but tumour uptake was relatively low. However, no new tumour growth was seen in any of the mice subsequent to therapy injections and 1 mouse showed complete remission within 5 weeks of injection. Further animal and human studies will need to be performed to determine the potential role of this modified 118 Re(V)DMSA in patients with MTC

    Anaplastic thyroid carcinoma (ATC) has among the worst prognoses of any solid malignancy. The low incidence of the disease has in part precluded systematic clinical trials and tissue collection, and there has been little progress in developing effective therapies. v-raf murine sarcoma viral oncogene homolog B (BRAF) and tumor protein p53 (TP53) mutations cooccur in a high proportion of ATCs, particularly those associated with a precursor papillary thyroid carcinoma (PTC). To develop an adult-onset model of BRAF-mutant ATC, we generated a thyroid-specific CreER transgenic mouse. We used a Cre-regulated BrafV600E mouse and a conditional Trp53 allelic series to demonstrate that p53 constrains progression from PTC to ATC. Gene expression and immunohistochemical analyses of murine tumors identified the cardinal features of human ATC including loss of differentiation, local invasion, distant metastasis, and rapid lethality. We used small-animal ultrasound imaging to monitor autochthonous tumors and showed that treatment with the selective BRAF inhibitor PLX4720 improved survival but did not lead to tumor regression or suppress signaling through the MAPK pathway. The combination of PLX4720 and the mapk/Erk kinase (MEK) inhibitor PD0325901 more completely suppressed MAPK pathway activation in mouse and human ATC cell lines and improved the structural response and survival of ATC-bearing animals. This model expands the limited repertoire of autochthonous models of clinically aggressive thyroid cancer, and these data suggest that small-molecule MAPK pathway inhibitors hold clinical promise in the treatment of advanced thyroid carcinoma.

    To assess the efficacy of sonography for discriminating nodular Hashimoto thyroiditis from papillary thyroid carcinoma in patients with sonographically evident diffuse Hashimoto thyroiditis. This study included 20 patients with 24 surgically confirmed Hashimoto thyroiditis nodules and 40 patients with 40 papillary thyroid carcinoma nodules; all had sonographically evident diffuse Hashimoto thyroiditis. A retrospective review of the sonograms was performed, and significant benign and malignant sonographic features were selected by univariate and multivariate analyses. The combined likelihood ratio was calculated as the product of each feature's likelihood ratio for papillary thyroid carcinoma. We compared the abilities of the original sonographic features and combined likelihood ratios in diagnosing nodular Hashimoto thyroiditis and papillary thyroid carcinoma by their sensitivity, specificity, and Youden index. The diagnostic capabilities of the sonographic features varied greatly, with Youden indices ranging from 0.175 to 0.700. Compared with single features, combinations of features were unable to improve the Youden indices effectively because the sensitivity and specificity usually changed in opposite directions. For combined likelihood ratios, however, the sensitivity improved greatly without an obvious reduction in specificity, which resulted in the maximum Youden index (0.825). With a combined likelihood ratio greater than 7.00 as the diagnostic criterion for papillary thyroid carcinoma, sensitivity reached 82.5%, whereas specificity remained at 100.0%. With a combined likelihood ratio less than 1.00 for nodular Hashimoto thyroiditis, sensitivity and specificity were 90.0% and 92.5%, respectively. Several sonographic features of nodular Hashimoto thyroiditis and papillary thyroid carcinoma in a background of diffuse Hashimoto thyroiditis were significantly different. The combined likelihood ratio may be superior to original sonographic features for

    Pre-therapeutic blood dosimetry prior to a high-dose radioiodine therapy (RAIT) is recommended and a blood dose of 2 Gy is considered to be safe. In this study, changes in the blood cell count after radioiodine therapy of high risk differentiated thyroid carcinoma (DTC) were analyzed and compared with the results of the pre-therapeutic blood dosimetry using 124 I. Moreover, the influence of different modes of TSH stimulation and the number of preceding radioiodine therapies on the blood dose were assessed. 198 patients with locally advanced or metastasized DTC received a pre-therapeutic blood dosimetry using 124 I. To analyze the influence of the modes of TSH stimulation and the number of preceding RAITs on blood dose subgroups were built as follows: patients with endogenous TSH stimulation versus patients with exogenous TSH stimulation and patients with no preceding RAIT versus patients with at least one preceding RAIT. In 124/198 patients subsequent RAIT was performed. In 73/124 patients, hemograms were performed from day 2 to 12 month after RAIT. There was no high-grade bone marrow toxicity (id est (i.e.) ≥grade 3) in patients receiving less than 2 Gy blood dose-independent of the therapeutic history. Within the first month after radioiodine therapy, there was an overall decrease in the white blood cell and platelet counts. The erythrocyte count was essentially stable. There was a correlation between cell count decrease and predicted blood doses (Spearman's correlation coefficient >-0.6 each) for the white cell line and the platelets. With regard to the subgroups, the blood dose per administered 131 I activity (BDpA) was significantly higher in patients with endogenous TSH stimulation (median 0.08 Gy/GBq) than in patients with exogenous TSH stimulation (0.06 Gy/GBq) and in patients with no previous RAIT (0.08 Gy/GBq) compared to patients who had previously undergone at least one RAIT (0.07 Gy/GBq). The range of BDpA among DTC patients is rather wide. Our

    Full Text Available Anaplastic thyroid carcinoma (ATC is the most aggressive form of thyroid cancer. It shows a wide spectrum of morphological presentations and the diagnosis could be challenging due to its high degree of dedifferentiation. Molecular and genetic features of ATC are widely heterogeneous as well and many efforts have been made to find a common profile in order to clarify its cancerogenetic process. A comprehensive review of the current literature is here performed, focusing on histopathological and genetic features.

    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 131 I 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 ( [es

    It is generally considered impossible to differentiate follicular carcinomas from follicular adenomas by means of ultrasonography or cytology before surgery. Therefore, follicular carcinoma is histopathologically diagnosed by verifying capsular and/or vascular invasion after surgery. However, ultrasonography may play an important role in diagnosing follicular carcinoma preoperatively in a small number of cases. Four cases of follicular carcinoma or follicular neoplasm that transformed from a benign thyroid tumor and demonstrated a "nodule in nodule" appearance on ultrasonography are presented in this report. Characteristic ultrasound features of such patients are: (1) a "nodule in nodule" appearance, (2) a well-defined boundary line between the nodules, and (3) separate distribution of blood signals within each nodule. A small number of patients with follicular carcinomas or follicular neoplasms may present with a "nodule in nodule" appearance on ultrasonography. It was suggested a long time ago that follicular carcinomas may develop from benign thyroid tumors. The fact that follicular carcinomas appear within benign tumors may be evidence of thyroid tumorigenesis.

    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.

    Thyroid cancer is a rare malignancy with wide inter ethnic and geographic variations. In Germany thyroid carcinoma is the 13. most frequent malignancy (2.7 new cases yearly per 100,000 inhabitants). The overall temporal incidence is increasing slightly in recent years. The most common types of cancer are papillary (60-80%) and follicular cancers (10-20%). The relevant prognostic indicators are tumor stage and distant metastases. The mean survival rates in papillary thyroid cancer usually exceed 90%, whereas in follicular thyroid cancer they amount to approximately 80%. The standard treatment procedure in differentiated papillary and follicular thyroid cancer consists of total thyroidectomy followed by adjuvant ablative therapy with radioiodine. Only in papillary thyroid cancer stage pT{sub 1}N{sub 0}M{sub 0} lobectomy alone is considered to be appropriate. In patients with locally invasive differentiated thyroid cancers stage pT{sub 4} adjuvant percutaneous radiation therapy is a treatment option. Radioiodine therapy has to be performed under the stimulative influence of TSH. Usually TSH suppressive medication with Levothyroxine has to be withdrawn approximately 4 weeks prior to radioiodine therapy. In the future, exogenous stimulation by recombinant TSH may be used instead of thyroid hormone withdrawal. It has been proved by different studies that ablative radioiodine therapy reduces the frequency of recurrences and tumor spread in patients with thyroid cancer significantly. In patients with distant metastases, up to 50% of complete responses may be achieved with radioiodine treatment.

    Hypothyroidism is a common adverse event after head and neck radiotherapy in human medicine, but uncommonly reported in canine patients. Records of 21 dogs with histologically or cytologically confirmed thyroid carcinoma receiving definitive or hypofractionated radiotherapy were reviewed. Nine cases received 48 Gy in 12 fractions, 10 received 36 Gy in 4 fractions and 2 received 32 Gy in 4 fractions. Seventeen cases had radiotherapy in a post-operative setting. Ten cases developed hypothyroidism (47.6%) after radiotherapy. The development of hypothyroidism was not associated with the radiotherapy protocol used. Median time to diagnosis of hypothyroidism was 6 months (range, 1-13 months). Hypothyroidism is a common side effect following radiotherapy for thyroid carcinomas. Monitoring of thyroid function following radiotherapy is recommended. No specific risk factors have been identified. © 2015 John Wiley & Sons Ltd.

    Thyroid metastasis is rare. The most common primary malignancy of thyroid metastasis worldwide is known to be renal cell carcinoma, but the most common primary malignancy in South Korea is breast cancer. Many studies have reported that primary renal cell carcinoma is almost unilateral and thyroid metastasis from renal cell carcinoma is a nearly ipsilateral, single lesion. We report a case of pyramidal lobe metastasis from renal cell carcinoma.

    2005-01-01

    In the last 15 years, several concepts have been developed to further improve the outcome of radioiodine therapy in functional thyroid autonomy. Results of radioiodine therapy in functional autonomy are considerably better than in Graves' disease. All of the currently-applied concepts offer healing rates of 75-100%, but they differ considerably in the hypothyreosis rates attained. The target volume can be precisely determined by sonography only in unifocal autonomy. In the case of multifocal and disseminated autonomy, the entire thyroid is taken as the target volume and the focal dose is reduced ('dosimetric compromise'). TcTUs-based dose concepts calculate the functionally autonomous volume from the TcTUs and replace the target volume by sonography, in the TcTUs-adapted dose concepts, sonographic target volume is left and the focal dose varied in dependence of the suppression uptake. The objective is to attain a high rate of success with a low rate of hypothyreosis. (orig.)

    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.

    Background: A rise in the incidence of thyroid cancer has been reported in several countries, and the increase is only seen in the papillary type. Increased detection due to higher resolution ultrasound and fine needle aspiration has been proposed as the explanation, recent registry studies however...... question this assumption. Methods: National, unselected, prospective cohort study of 1350 papillary thyroid cancer patients in Denmark from 1996 to 2008. Objective: To analyze changes in incidence by time and to identify factors which might influence detection rate. Results: A rise in incidence is seen...... thyroid surgery could not be confirmed. Conclusion: This study shows a significant rise in incidence of papillary thyroid carcinoma in Denmark from 1996 to 2008, which is not explained by increased use of preoperative diagnostic modalities. Other reasons need to be considered....

  14. Thyroid metastasis as initial presentation of clear cell renal carcinoma.

    Ramírez-Plaza, César Pablo; Domínguez-López, Marta Elena; Blanco-Reina, Francisco

    2015-01-01

    Metastatic tumors account for 1.4-2.5% of thyroid malignancies. About 25-30% of patients with clear cell renal carcinoma (CCRC) have distant metastasis at the time of diagnosis, being the thyroid gland a rare localization [5%]. A 62-year woman who underwent a cervical ultrasonography and a PAAF biopsy reporting atypical follicular proliferation with a few intranuclear vacuoles "suggestive" of thyroid papillary cancer in the context of a multinodular goiter was reported. A total thyroidectomy was performed and the histology of a clear cell renal carcinoma (CCRC) was described in four nodules of the thyroid gland. A CT scan was performed and a renal giant right tumor was found. The patient underwent an eventful radical right nephrectomy and the diagnosis of CCRC was confirmed. Thyroid metastasis (TM) from CCRC are usually apparent in a metachronic context during the follow-up of a treated primary (even many years after) but may sometimes be present at the same time than the primary renal tumor. Our case is exceptional because the TM was the first evidence of the CCRC, which was subsequently diagnosed and treated. The possibility of finding of an incidental metastatic tumor in the thyroid gland from a previous unknown and non-diganosed primary (as CCRC in our case was) is rare and account only for less than 1% of malignancies. Nonetheless, the thyroid gland is a frequent site of metastasis and the presence of "de novo" thyroid nodules in oncologic patients must be always considered and studied.

    Full Text Available Iodide uptake across the membranes of thyroid follicular cells and cancer cells occurs through an active transport process mediated by the sodium-iodide symporter (NIS. The rat and human NIS-coding genes were cloned and identified in 1996. Evaluation of NIS gene and protein expression is critical for the management of thyroid cancer, and several approaches to increase NIS levels have been tried. Identification of the NIS gene has provided a means of expanding its role in radionuclide therapy and molecular target-specific theragnosis (therapy and diagnosis using the same molecular target. In this article, we describe the relationship between NIS expression and the thyroid carcinoma treatment using I-131 and alternative therapeutic approaches.

    The thyroid neoplasm is easily entered in the accounts in Martinique with the Tumor Registry created in 1981. This is not a frequent cancer but its frequency grew since 1981 till 1995. The treatment of the well differentiated thyroid cancer is well standardized with a total thyroidectomy generally followed by a metabolic thyroidectomy with 131 I. The follow-up is composed by clinical exam, TSH and thyroglobulin measurements. The results are very good and we mean to continue this strategy refining it for the little papillary tumors and using the recombinant TSH. The Tchernobyl event in 1986 generated new epidemiological considerations and has been the object of multiples studies.The studies realized in such a very distant site like Martinique permitted the realization of comparisons with the Tumor Registry of the 'Bas Rhin' in France a geographical area that could have been concerned by the disaster. The result of this study fends a growth of the incidence of the thyroid neoplasm almost identical with that registered in the mainland with a net increase for the papillary neoplasms. We may then conclude that the growth percentage since 1981 till 1995 due to the availability and more frequent using of many new diagnostic means less operator-dependent than before. By this descriptive study we may purport that the incidence of the thyroid cancer is low (4,45 per 100000 population for women and 0,9 per 100000 population for men). Treatment is consensual and thanks to the lifelong administration of exogenous thyroid hormone the quality of life of these patients is maintained along with a sure recovery in most of the cases. The mortality due to the thyroid cancer is very low in the orthoplasic form (less than 1 % of all types of cancer). The precocious screening of the thyroid neoplasm has to enter then in the guidelines in medical education. It consists in the systematical exploring of a thyroid nodule by clinical exam and by ultrasonography, radioisotope scanning with Tc

    Full Text Available Abstract Background Despite the apparent low incidence of cancer metastatic to the thyroid, autopsy and clinical series suggest it is more common than generally. Although lung, renal, and breast cancer are probably the most common primary sites, a number of cancers have been reported to metastasize to the thyroid synchronously with diagnosis of primary tumor or years after apparently curative treatment. Case presentation We report a rare case of a hepatocellular carcinoma metasatic to the thyroid. The patient presented seven months after original diagnosis and treatment with hepatic lobectomy with multiple neck lesions producing a mass effect on the trachea and bilateral lymphadenopathy. Fine-needle aspiration revealed highly anaplastic carcinoma, and immunohistochemistry confirmed hepatocellular carcinoma. The patient received total thyroidectomy as palliative therapy because of the presence of multiple recurrent lesions in the liver. Conclusion Clinicians should consider the possibility of metastatic cancer in each patient who presents with a new thyroid mass, especially those with a history of cancer, however remote. In cases where cytology or histology is not diagnostic, immunohistochemistry may be definitive in making the diagnosis.

    A hyperfunctioning differentiated thyroid carcinoma is a rare occurrence. Nevertheless, this diagnosis must be considered in a scintigraphically hot nodule if there is a clinical or sonographic suggestion of malignancy. The case of a 57-year old patient with hyperthyreosis and a scintigraphically hot thyroid nodule is presented. Further evaluation led to the diagnosis of a differentiated thyroid carcinoma with extensive lymph node and pulmonary metastases (pT2b, pN1b, pM1). The scintigraphically hot nodule corresponded to the primary tumor, whereas scintigraphic detection of the lymph node metastases was only possible postoperatively. Extensive resection of the lymph node metastases was achieved by the intraoperative application of a gamma probe (2nd operation). This allowed sufficient uptake of radioiodine in the pulmonary metastases for their detection and subsequent devitalization by radioiodine therapy. Complete elimination of all tumor tissue was documented at a control follow-up after six months. Gamma probe-guided surgery may allow for additional removement of non-palpable lymph node metastases. In selected cases this may optimize the surgical results and thereby facilitate the subsequent radioiodine elimination of advanced differentiated thyroid carcinomas. (author)

    A 70-year-old man was diagnosed as thyroid medullary carcinoma with multiple bone metastases. He underwent total thyroidectomy and cervical lymph node dissection. After one year, the pain from his bone lesions was becoming severe. To relieve the pain, he was administered opioids and external-beam radiation therapy. However, he continued to have substantial multiple bone pain. We used combination therapy of strontium-89 chloride for the treatment of widespread multiple bone pain and external-beam radiation therapy for localized pain. That combination therapy was effective and improved the quality of life (QOL) of the patient. We used strontium-89 chloride four times within one year, and no serious side effects occurred during therapy. Our thoroughly investigated case suggests that strontium-89 therapy is one of the effective and safe therapies for patients with painful bone metastases of thyroid medullary carcinoma. (author)

    Lung metastases (LMs) and their radioiodine uptake affect prognosis in patients with differentiated thyroid carcinoma (DTC). We herein investigate the value of metabolic tumor volume (MTV) in LMs on positron emission tomography/computed tomography (PET/CT) using 2-[F-18]-fluoro-2-deoxy-D-glucose (F-18 FDG PET/CT) in predicting short-term progression after initial I-131 therapy in DTC patients. We retrospectively evaluated 111 DTC patients with LMs. Diagnostic CT and I-131 scintigraphy were performed within 1 week of I-131 therapy. Maximum standardized uptake value (SUVmax) and total MTV (MTVtotal) were compared between patients with I-131-positive and I-131-negative LMs and between patients with and without short-term progression. Correlation analyses were performed between F-18 FDG PET/CT parameters and thyroglobulin (TG) level, and predictive factors for short-term progression were analyzed by logistic regression and receiver operating characteristic curve analysis. Patients with short-term progression had significantly higher SUVmax and MTVtotal than those without. TG levels were significantly correlated with SUVmax ( r = 0.21) and MTVtotal ( r = 0.51) after I-131 therapy. MTVtotal showed significant association (χ 2 = 16.5, odds ratio = 0.02) with short-term progression after initial I-131 therapy and had the highest predictive value of all the putative risk factors. MTVtotal in LMs on F-18 FDG PET/CT is an independent predictive factor with a high predictive value for short-term progression of DTC after initial I-131 therapy. It is recommended that F-18 FDG PET/CT be performed before planning therapy during the evaluation of DTC patients with LM.

Numerous studies have evaluated the effect of (131)I therapy, but results have been conflicting due to differences in design, sample size, patient selection, and dose calculation. It seems clear that no single factor reliably predicts the outcome...... of an exact thyroid dose is error-prone due to imprecise measurement of the (131)I biokinetics, and the importance of internal dosimetric factors, such as the thyroid follicle size, is probably underestimated.

    Full Text Available Struma ovarii is an uncommon type of ovarian mature teratoma with a predominant thyroid component. The morphological spectrum of the thyroid tissue ranges from that of normal thyroid to proliferative adenoma-like lesions and thyroid-type carcinomas (malignant transformation. The histologic features of ovarian strumal lesions sometimes cause diagnostic problems due to the confusion with other types of ovarian neoplasms and the difficulty in the prediction of their clinical behavior. We report an extremely rare case of poorly differentiated thyroid carcinoma arising in struma ovarii. A 22-year-old woman presented with a 15 cm right ovarian mass. The tumor showed a predominantly tubular pattern which raised a differential diagnosis between endometrioid adenocarcinoma and Sertoli cell tumor. A review of the gross specimen with additional tissue sampling helped identify the teratomatous and strumal nature, with a support by immunohistochemical staining. Despite FIGO stage IA by optimal staging procedure and the absence of identifiable lymphovascular invasion, the patient developed pulmonary metastasis 15 months after surgery and died from the progression of the disease 7 years after the diagnosis. This case emphasizes the importance of macroscopic examination of the specimen and the awareness of this uncommon tumor in the differential diagnosis of ovarian neoplasms.

    Thyroid metastasis from nasopharyngeal carcinoma is rare. Metastasis of nasopharyngeal carcinoma to the thyroid gland with subsequent metastatic abdominal lymph nodes hasn't been reported before. We want to share our experience about the treatment choice. A 27-year-old man was diagnosed with nasopharyngeal nonkeratinizing carcinoma in August 2004. In March 2013 he underwent a thyroid carcinoma radical operation, and histological examination revealed metastasis to the thyroid gland from nasopharyngeal carcinoma. An 18F-FDG-PET/CT scan and biopsy showed metastatic abdominal lymph nodes of nasopharyngeal carcinoma in April 2015. A 27-year-old man was diagnosed with metastasis of nasopharyngeal carcinoma to the thyroid gland with subsequent metastatic abdominal lymph nodes. The patient was treated with concurrent chemotherapy and radiotherapy for nasopharyngeal carcinoma and metastasis to the thyroid gland. The metastases to the abdominal lymph nodes received chemotherapy. After 6 cycles of chemotherapy with gemcitabine, cisplatin, and 5-fluorouracil for metastasis to the abdominal lymph nodes, the patient is currently asymptomatic with stable disease and improved quality of life. The treatment choice for metastasis of nasopharyngeal carcinoma depends on the clinical disease extent, and surgery and/or chemo-radiation therapy must be drafted to the individual patient in order to improve the prognosis and quality of life.

    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

    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.

    Differentiated thyroid cancer is 85% of all thyroid cancer, and is known to have good prognosis with proper surgery and radioiodine therapy. But 4% of papillary carcinoma and 36% of follicular carcinoma present with distant metastasis. Even if the patient had distant metastasis, total thyroidectomy and radioiodine therapy show good response. Forty seven percent of bone metastases are found in the initial diagnosis, in which vertebral metastases is 29%, pelvic metastases 22%. The metastases to vertebrae often combine spinal cord compression, making it difficult to deliver enough radiation dose to the lesion with radioiodine or external beam irradiation. Brain metastases is found in less than 1% of thyroid cancer, and is also difficult to cure. In Korea Cancer Center Hospital, from 1997 to 2002, we analyzed 437 patients with thyroid cancer who were treated with radioiodine after total thyroidectomy. There were four patients with brain metastases, and 32 patients with vertebral metastases. In four patients with brain metastases, one patient, who also had bone metastases, received high dose radioiodine therapy after total thyroidectomy, and is alive for more than 15 months. Another patients received total thyroidectomy, radioiodine therapy and external irradiation therapy, and survived 22 months. Two patients refused further treatment and died in one month. I-131 uptake in the metastatic lesion in brain is reported to be 17%, and multimodality therapy with surgery, radioiodine therapy, external irradiation and chemotherapy may improve the prognosis. In 32 patients with vertebral metastases, 19 patients (59.4%) showed I-131 uptake after high dose radioiodine therapy, and 5 year survival rate was 65.8%. 13 patients without I-131 uptake after radioiodine therapy had 26.9% of 5 year survival rate. In 11 patients with spinal cord compression, 7 patients received high dose radioiodine therapy and external irradiation after total thyroidectomy and spinal surgery, and six

    Thyroid cancer is the endocrine tumor that bears the highest incidence with 33 550 new cases per year. It bears an excellent prognosis with a mortality of 1530 patients per year (Jemal et al.; 2007). We have been treating patients with thyroid carcinoma during many years without many innovations. Recently, we have assisted to the development of new agents for the treatment of this disease with unexpected good results. Here we present a review with the old and new methods for the treatment of this disease. PMID:21048836

    Squamous cell carcinoma of the larynx and hypopharynx has the potential to invade the thyroid gland. Despite this risk, the proposition of either partial or total thyroidectomy as part of the surgical treatment of all such cases remains controversial. To evaluate the frequency of invasion of the thyroid gland in patients with advanced laryngeal or hypopharyngeal squamous cell carcinoma submitted to total laryngectomy or pharyngolaryngectomy and thyroidectomy; to determine whether clinic-pathological characteristics can predict glandular involvement. A retrospective case series with chart review, from January 1998 to July 2013, was undertaken in a tertiary care university medical center. An inception cohort of 83 patients with larynx/hypopharynx squamous cell carcinoma was considered. All patients had advanced stage disease (clinically T3-T4) and underwent total laryngectomy or total pharyngolaryngectomy in association with thyroidectomy. Adjuvant therapy was indicated when tumor or neck conditions required. Frequency of thyroid cartilage invasion was calculated; univariate and multivariate analysis of demographic, clinical and pathological characteristics associated with cartilage invasion were performed. The overall frequency of invasion of the thyroid gland was 18.1%. Glandular involvement was associated with invasion of the following structures: anterior commissure (odds ratio=5.13; 95% confidence interval 1.07-24.5), subglottis (odds ratio=12.44; 95% confidence interval 1.55-100.00) and cricoid cartilage (odds ratio=15.95; 95% confidence interval 4.23-60.11). Invasion of the thyroid gland is uncommon in the context of laryngopharyngeal squamous cell carcinoma. Clinical and pathological features such as invasion of the anterior commissure, subglottis and cricoid cartilage are more associated with glandular invasion.

    Objective: RET / PTC gene rearrangement can lead to aberrant activation of tyrosine kinase receptors, which is a common mutation in papillary thyroid carcinoma (PTC). This study focuses on the association of RET / PTC rearrangements with PTC clinical factors. Methods: From January 2011 to December 2013, a total of 114 patients with PTC were enrolled in this study. Clinicopathological parameters, lifestyle, and thyroid hormone levels were collected. RET / PTC rearrangements were detected by TaqMan PCR and verified by Sanger sequencing.Data were analyzed with SPSS software, including chi-square test, Fisher ' s exact test, Mann - Whitney U test, Student ' s t -test, and Logistic regression. Results: RET / PTC rearrangements were not found in all paracancerous normal thyroid tissues, and were detected in 23.68% (27/114) of PTC. Further analysis revealed no correlation between RET / PTC rearrangement and thyroid function, clinicopathologic parameters, and lifestyle in the total PTC group or in the subgroup of patients with concomitant diseases (including Hashimoto's thyroiditis and nodular goiter). But in the subgroup of PTC without concomitant disease, RET / PTC rearrangement was associated with tumor multifocal ( P =0.018), and RET / PTC -positive PTC patients had an increased risk of tumor multifocal ( OR =5.57, 95% CI 1.39-22.33). It was also found that RET / PTC rearrangement was associated with an abnormal increase in TSH level of one month after surgery ( P = 0.037). Conclusion: Nodular goiter and Hashimoto 's thyroiditis may be a confounding factor in PTC. RET / PTC rearrangement may play an important role in the occurrence of thyroid carcinoma multifocal after exclusion of this confounding factor.

    Full Text Available BACKGROUND Thyroid carcinoma accounts for less than 1% of cancer cases. In the Indian subcontinent, thyroid carcinoma exhibits a varied disease profile and geographic differences in the pattern of cancer, the knowledge of which impacts a more favourable clinical outcome. The present study aims to profile Thyroid carcinoma in areas of age, gender, geographic domicile, morphology & clinical features and referral paradigm of cases in King George Hospital, Visakhapatnam, the tertiary referral hospital for coastal Andhra Pradesh. METHODS & MATERIALS The Retrospective Study 1988-2004 includes 188 patients who attended Department of Nuclear Medicine for pre & postoperative nuclear scan, thyroid carcinoma treatment protocol, whose clinical features, relevant laboratory data, histopathological reports & prognosis were analysed. RESULTS Papillary thyroid carcinoma was present in 79% and Follicular thyroid carcinoma in 19%, Anaplastic & Medullary Thyroid Carcinoma in 2% of cases (n=188, male to female ratio 1:0.62. Coastal city of Visakhapatnam recorded highest 59% of cases who were in their 3rd and 4th decades. West Godavari District had lowest at 5%. Clinical presentation of cases of Thyroid carcinoma as a Nodule (61% which was the most common form lead to maximum number of referrals (n=82 from the Department of Surgery, King George Hospital. CONCLUSION In coastal Andhra Pradesh, papillary thyroid carcinoma was the most dominant form. Women were more affected than men. Painless thyroid nodule was the most common clinical feature. Coastal city of Visakhapatnam recorded highest number of cases and maximum referrals were from Department of Surgery.

    Full Text Available Medullary thyroid carcinoma (MTC commonly metastasizes locally to the cervical lymph nodes and distantly to the liver, lungs and bones. Metastatic involvement of the muscles is extremely rare. We reported an unusual case of undiagnosed MTC presenting with symptoms related to metastatic lesions of the brachoradialis and the gluteus medius muscles. A 53-year-old man consulted for a painful mass of the right forearm and atrophy of the quadriceps. Ultrasonography revealed a heterogeneous collection in the forearm. Computed tomographic scan showed a mass in the right lung, an enlargement of mediastinal lymph nodes and solid masses in the right gluteus medius and the left iliopoas muscle extending to the left iliac bone. Pulmonary biopsies displayed findings consistent with metastatic MTC. Fine needle aspiration cytology from the right arm swelling revealed a lesion with the same calcitonin immunostaining patterns as the lung metastasis. The diagnosis of multiple metastases (lung, muscle and bone of MTC is established. The patient has received local radiation therapy and was planned for chemotherapy. Muscular metastases from MTC are rare and although their prognosis is poor, local treatment may be worthwhile.

    Treatment with radioiodine is a standard procedure for patients with well-differentiated thyroid cancer, but the main approach to the therapy is still empiric, consisting of the administration of fixed activities. A predictive individualized dosimetric study may represent an important tool for physicians to determine the best activity to prescribe. The aim of this work is to compare red marrow and blood absorbed dose values obtained in the pre-treatment (PT) dosimetry phase with those obtained in the in-treatment (IT) dosimetry phase in order to estimate the predictive power of PT trial doses and to determine if they can be used as a decision-making tool to safely administer higher (131)I activity to potentially increase the efficacy of treatment. The PT and IT dosimetry for 50 patients has been evaluated using three different dosimetric approaches. In all three approaches blood and red marrow doses, are calculated as the sum of two components, the dose from (131)I activity in the blood and the dose from (131)I activity located in the remainder of the body (i.e. the blood and whole-body contributions to the total dose). PT and IT dose values to blood and red marrow appear to be well correlated irrespective of the dosimetric approach used. Linear regression analyses of PT and IT total doses, for blood and red marrow, and the whole-body contribution to these doses, showed consistent best fit slope and correlation coefficient values of approximately 0.9 and 0.6, respectively: analyses of the blood dose contribution to the total doses also yielded similar values for the best fit slope but with correlation coefficient values of approximately 0.4 reflecting the greater variance in these dose estimates. These findings suggest that pre-treatment red marrow dose assessments may represent an important tool to personalize metastatic thyroid cancer treatment, removing the constraints of a fixed activity approach and permitting potentially more effective higher (131)I

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

    Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen. Metastasis was also found in lungs, skull and adrenal glands after which the patient was diagnosed with stage IVc anaplastic thyroid carcinoma (ATC). After careful consideration of patient's clinical condition with multiple poor prognostic factors, medical therapy was withheld and she was discharged on hospice care. The patient expired after 1 month. In ATC, metastasis to subcutaneous tissue is an extremely rare occurrence of which there is hardly any evidence in literature. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Samuel, A.M.; Rajashekharrao, B.

    1999-01-01

    Radioiodine ( 131 I) therapy has been in use for the treatment of thyroid diseases. Although the use of 131 I has been in vogue for a long time, its use in therapy for well-differentiated thyroid cancer is still controversial. This is because, thyroid cancers (TC) are generally slow growing tumors, with low mortality and normal spans of survival. To record recurrence and mortality, long-term follow-up studies over a period of two to three decades are needed to establish definite conclusions on the acceptable modes of treatment. The most reliable conclusions regarding 131 I treatment are obtained from studies reported on a large series of patients followed over a period of 3 decades or more from a single institute with a more or less unchanged protocol of management

    Anaplastic thyroid carcinoma is rare but carries a poor prognosis. Anaplastic thyroid carcinoma leads to tracheal compression, airway compromise and eventually death. Airway compromise, a particularly distressing symptom, can be palliated with tracheal stenting. A retrospective case note analysis was conducted of patients diagnosed with anaplastic thyroid carcinoma between July 2003 and July 2013. Twelve patients with anaplastic thyroid carcinoma were identified. Four patients underwent palliative tracheal stenting. Three patients had no dyspnoea at the time of stenting. Two stented patients subsequently developed dyspnoea secondary to stent migration; this was managed successfully with stent exchange. The other stented patient remained asymptomatic with regards to dyspnoea. All non-stented patients died with or from airway compromise. Tracheal stenting is a relatively safe and effective method for palliation of distressing airway symptoms in patients with anaplastic thyroid carcinoma. Early prophylactic tracheal stenting in anaplastic thyroid carcinoma may be an effective option to prevent development of airway compromise as the disease progresses.

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

    Background: Carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. In the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. In cases which have morphological overlap, immunohistochemistry is needed for differential diagnosis. The purpose of this study is to investigate the expressions of CD56, HBME-1, cytokeratin 19 (CK19) antibodies in papillary thyroid carcinoma (PTC) and thyroid nodular lesions and their contributions to differential diagnosis. Materials and Methods: In this study, 47 PTCs (26 follicular variant, 21 classic type) and 26 benign thyroid lesions (15 nodular hyperplasia, 10 follicular adenomas, 1 Hurtle cell adenoma) were analyzed retrospectively. HBME-1, CK19, and CD56 antibodies were performed with immunohistochemical methods. The results were evaluated statistically. Results: +3 staining with HBME-1 and CK19 was observed in 72.3% and 83% of patients with PTC. In 95.7% of PTC cases, loss of CD56 expressions in various degrees was identified. A statistically significant difference was detected in HBME-1, CK19, and CD56 expressions between PTCs and benign lesions (P < 0.001). Conclusion: In our study, positive staining of HBME-1, CK19, and loosing expression of CD56 that supports malignancy was found and concluded that CD56 is a helpful antibody for the differential diagnosis of benign and malignant lesions and may increase the diagnostic accuracy when used with HBME-1 and CK19.

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

    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

    The most common causes of intraocular metastases are breast and lung cancers, although many other neoplasms can metastasize to the eye. Most of the metastases are located in the posterior pole and the choroid is more often involved than the retina. We present a case of a choroidal metastasis from a papillary carcinoma of the thyroid, associated with a massive subretinal hemorrhage. Findings with color Doppler ultrasound are emphasized.

  10. Follicular thyroid carcinoma mimicking meningioma: A case report

    2012-02-01

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

    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

    Full text: Introduction: Because brain metastasis from well differentiated thyroid carcinoma is rare, management of patients presenting with this condition lacks consensus. A recent review of the literature found 17 reports of 75 cases from 1966-2001 in which 28 metastasis were from the brain, 5 from the spinal cord, 2 to both brain and spinal cord, We report our 5 cases with a focus on the last patient. Clinical presentation: A 66-year-old female treated by us for the past 10 years for papillary carcinoma of the thyroid with metastasis to bone. She presented in July 2003 with sudden onset of seizure. A non contrast CT scan demonstrated a solitary lesion in the right anterior high parietal region with a possible second lesion. Intervention: She underwent right frontal craniotomy to expose superior sagittal sinus. An inter-hemispheric approach demonstrated a tumor in the supra-meningeal gyrus that was attached to the calloso-meningeal artery. The histopathology of the surgical specimen confirmed a follicular variant of papillary carcinoma of the thyroid. She then received 11100 MBq 1-131 irradiation, Conclusion: the best therapeutic option for brain metastasis seems to be surgical resection with or without post operative Irradiation with 1-131. Central nervous system metastasis should always be investigated and treated aggressively to improve patients' long term outcome. (author)

    The purpose of this study was to analyze the results of the combined modality treatment and radiation therapy using 6.3 MeV fast neutrons c. The study included 45 patients with thyroid gland cancers who received the combined modality treatment and radiation therapy alone with the use of 6.3 MeV fast neutrons generated within U-120 cyclotron. The clinical trial of neutron-photon therapy used alone and in combination with the surgery for the patients with aggressive forms of thyroid cancer showed feasibility of increasing the effectiveness of treatment due to the reduction in the incidence of local recurrences. In addition, satisfactory treatment tolerance and absence of severe specific complications dictate the necessity of prospective studies to improve treatment outcomes.

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

    We performed this study to compare the clinicopathologic features and outcomes between the patients with poorly differentiated thyroid carcinoma (PDTC) and the patients with the aggressive variants of papillary thyroid carcinoma (PTC). To evaluate the prognostic factors for survival of the patients with PDTC, we selected 49 patients with PDTC and 23 patients with the aggressive variants of PTC from three hospitals during the recent 15 years. The five-year survival rate and clinicopathologic features of the patients with PDTC were not different from those of the patients with the aggressive variants of PTC. Univariate analysis revealed the significant poor prognostic factors for survival of the patients with PDTC and the aggressive variants of PTC as follows: an age more than 45 years, a tumor size larger than 4 cm, the presence of tumor invasion to extrathyroidal tissue or the trachea, the presence of cervical lymph node invasion, the presence of distant metastasis, the absence of high-dose radioactive iodine (RAI) therapy, and tumor, nodes and metastasis (TNM) stage II, III and IV. Distant metastasis and high-dose RAI therapy were independent significant predictors for survival of the patients with PDTC and the aggressive variants of PTC on multivariate analysis. However, distant metastasis was the only independent significant predictors for survival of the patients with PDTC excluding patients with the aggressive variants of PTC. (author)

    Metastatic papillary thyroid carcinoma (PTC) without an identifiable primary tumor despite extensive microscopic examination of the thyroid gland is a rare but true phenomenon.We retrieved 7 of such cases and described in detail the clinical and pathologic features of these tumors. BRAF V600E immunohistochemistry and Sequenom molecular profile were conducted in selected cases. All patients harbored metastatic disease in the central (n=3), lateral (n=3), or both neck compartments (n=1). The histotype of the metastatic disease was PTC (n=5), poorly differentiated thyroid carcinoma in association with a PTC columnar variant (n=1), and anaplastic thyroid carcinoma in association with a PTC tall cell variant (n=1). Fibrosis was present in the thyroid of 5 patients. All patients with PTC were alive without evidence of recurrence. The 76-year-old patient with poorly differentiated thyroid carcinoma did not recur and died of unknown causes. Finally, the patient with anaplastic thyroid carcinoma was alive with distant metastasis at last follow-up. The median follow-up for this cohort was 2.2years (range, 0.8-17). BRAF V600E was detected in 4 of 6 cases by immunohistochemistry. In conclusion, metastatic nodal disease without identifiable thyroid primary is a rare but real phenomenon of unknown mechanisms. Although most tumors are low grade and well differentiated, aggressive behavior due to poorly differentiated or anaplastic carcinoma can happen. Most cases are BRAF V600E -positive thyroid tumors. A papillary carcinoma phenotype is found in all reported cases. Copyright © 2017 Elsevier Inc. All rights reserved.

    During a follow-up of 11 years of thyroid carcinoma 136 patients were repeatedly examined. 43% papillary, 43% follicular, 11% anaplastic and 2% medullary carcinomas was found. The incidence of these types of carcinoma differed considerably; the frequency peak of papillary carcinomas was reached in 45-year-old humans, that of the follicular carcinomas in people aged 60, that of the anaplastic carcinomas in 70-year-old humans. 84% of the patients was female. Classification in pTNM-system: 8% in pT1, 27% in pT2, 12% in pT3 and 49% in pT4. Local and distant metastases were found at a low rate equally in pT1, pT2 and pT3; 26% of patients in pT4 had local metastases and 18% had distant ones in addition. There were 6 patients with metastases of a differentiated adenocarcinoma accumulating no 131-iodine and with no thyroglobulin in serum. 29% of patients had after thyroidectomy an unilateral paresis of the nervus recurrens and 4% a bilateral one. 26% of patients had a permanent hypoparathyroidism after thyroidectomy.

    There is a potential hazard of thyroid cancer after exposure to external irradiation for the treatment of adolescent acne vulgaris. We noted a 60% incidence of thyroid carcinoma among 20 patients with such a history, who were operated on for thyroid nodules during a five-year period. Eighty-three percent of the patients with carcinoma had either a follicular or a mixed papillary-follicular carcinoma; 17% had a papillary carcinoma; 33% had regional node metastases; none had evidence of distant metastases. The interval between radiation exposure and thyroidectomy ranged from nine to 41 years. This association of thyroid neoplasms and a prior history of radiation for acne vulgaris may be coincidental and therefore remains to be proved by retrospective surveys of large numbers of treated patients with appropriate controls

    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.

  2. Surgical Management of Bulky Mediastinal Metastases in Follicular Thyroid Carcinoma

    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.

    Full Text Available Introduction Completion thyroidectomy is defined as the surgical removal of the remnant thyroid tissue following procedures of less than total or near-total thyroidectomy. Whether thyroid reoperations are associated with an increased complication risk is controversial. Objective A retrospective analysis was done of patients undergoing completion thyroidectomy for cancer of the thyroid who had undergone surgery elsewhere for solitary thyroid nodule. The incidence of surgical complications in these patients after reoperation was investigated in this study. Material and methods The study included a total of 53 patients who had undergone thyroid lobectomy for a solitary nodule as initial surgery elsewhere and were referred to our institute for completion thyroidectomy when the histopathology revealed malignancy. Results There were 53 patients, 43 females and 10 males. Their mean age was 34.7±12.12 years (range 19–65 years. After initial surgery, the histopathology revealed papillary carcinoma in 46 patients (86.8%, follicular carcinoma in 7 (13.2%. Fourteen out of 53 patients had recurrent laryngeal nerve palsy after initial surgery (26.4%. None of the patients had clinical hypocalcemia after the first surgery. One or more parathyroid glands were identified and preserved in 52 patients (98.1% in the process of completion thyroidectomy. No patient had additional recurrent nerve injury at the second surgery. The mean serum calcium value preoperatively was 8.96±0.39 mg/dL, and six months after surgery serum calcium was 8.74±0.56 mg/dL. Mean follow-up was 18 months. Transient hypoparathyroidism occurred in 24.5% patients. Five patients were lost to follow-up. Permanent and symptomatic hyperparathyroidism occurred in eight patients (16.67%. Conclusions Completion thyroidectomy is a safe and appropriate option in the management of well-differentiated thyroid cancer. It removes disease on the ipsilateral and contralateral side of the thyroid and

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

    Full Text Available In April 2006, a 55-year-old female presented with a thyroid mass and multiple skin nodules on scalp, forehead and neck. Fine needle aspiration cytology of thyroid mass and multiple skin nodules show tumor cells clusters in a repetitive microfollicular pattern on May-Grunwald-Giemsa stain suggestive of follicular thyroid carcinoma with metastasis to skin. Although follicular carcinoma have a propensity for vascular invasion and hematogenous dissemination, skin is not commonly involved. Only a few cases of cutaneous metastasis from follicular thyroid carcinoma are reported in the English language literature.

    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.

    Thyroid cancer is the most common endocrine neoplasia. The medullary thyroid carcinoma (MTC) is one of the most aggressive forms of thyroid malignancy,accounting for up to 10% of all types of this disease. The mode of inheritance of MTC is autosomal dominantly and gain of function mutations in the RET proto-oncogene are well known to contribute to its development. MTC occurs as hereditary (25%) and sporadic (75%) forms. Hereditary MTC has syndromic (multiple endocrine neoplasia type 2A, B; MEN2A, MEN2B) and non-syndromic (Familial MTC, FMTC) types. Over the last two decades, elucidation of the genetic basis of tumorigenesis has provided useful screening tools for affected families. Advances in genetic screening of the RET have enabled early detection of hereditary MTCs and prophylactic thyroidectomy for relatives who may not show any symptom sof the disease. In this review we emphasize the main RET mutations in syndromic and non syndromic forms of MTC, and focus on the importance of RET genetic screening for early diagnosis and management of MTC patients, based on American Thyroid Association guidelines and genotype-phenotype correlation.

    2014-01-01

    Renal cell carcinoma (RCC) is commonly known as the "internist's tumor" because of its unpredictable behavior. Metastasis to the thyroid gland is rarely found in clinical practice. We report a rare case of non-thyroid malignancies NTM from renal cell carcinoma 1.5 years after radical nephrectomy in a 58-year-old man with a rapidly growing neck mass. Malignant melanoma, breast carcinoma, lung, and skin cancer are the most common sources of non-thyroid malignancies (NTM). Although metastases of NTMs to the thyroid gland are uncommon in clinical practice, it should be considered in patients with a history of prior malignancy and a new thyroid mass. Isolated thyroid metastasis should be considered in patients with a previous history of cancer and newly developing thyroid mass. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    1983-05-01

    Two hundred and twelve papillary and 40 follicular carcinomas were found in 3002 thyroid glands examined from 1931 to 1975 in four Laboratories of Pathology that fairly cover northern Portugal. There was a striking preponderance of women both in papillary (female:male = 6.9:1) and follicular carcinoma (5.7:1). Sex-specific frequency of malignancy was significantly greater in men (13.3%) than in women (8.8%). The overall papillary/follicular ratio was 5.3:1 and did not significantly change throughout the study period. Papillary/follicular ratio was not significantly greater in litoral (5.5:1) than in regions with a low iodine intake and a relatively high prevalence of goiter (3.5:1). It is advanced that this high relative frequency of papillary carcinoma in northern Portugal, even in goiter areas, may reflect the existence of a racial factor since there is not enough evidence to support the influence of dietary iodine, previous irradiation and concurrent thyroiditis.

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

    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.

    The choice of treatment for a well-differentiated carcinoma (WDC) of the thyroid has remained controversial for several decades. This is unfortunate because WDC occurs in the young, particularly in women, and is compatible with several years of survival. A retrospective analysis of 417 cases of WDC of the thyroid treated by definitive surgery at the Tata Memorial Hospital for the 15-year period (1970 to 1985) form the basis of the conclusion drawn in the present report. These include cases that were referred primarily and those who underwent revision or completion thyroidectomy at the hospital after being treated elsewhere. All relevant data of the cases with WDC, including histopathology slides, were reviewed by an experienced pathologist

    To compare the morphometric features of papillary carcinomas with follicular neoplasias and benign lesions and to determine the potential role of nuclear morphometric features in their differential diagnosis. Morphometric features were investigated in the cytologic samples of 64 cases, including 27 benign lesions, 6 follicular neoplasias and 31 papillary carcinomas. We analyzed 6 morphometric parameters: nuclear area, nuclear perimeter, maximum diameter (MaxD), minimum diameter (MinD), form factor and ratio of MaxD/MinD. There were no significant differences between the benign lesion and follicular neoplasia groups for any nuclear parameters. However, between benign lesions and papillary carcinomas, there were significant differences for all parameters, except for form factor. Between follicular neoplasms and papillary carcinomas, only the MaxD/MinD ratio was significantly different. The results of this study indicate that the ratio of MaxD/MinD is a distinct nuclear morphometric feature for distinguishing papillary carcinoma from other thyroid lesions, and it may be employed with other cytologic criteria in diagnosing problematic cases.

    Secondary malignancy of the thyroid gland is uncommon, but it is a problem requiring ongoing recognition. As it is more common than primary thyroid malignancy, metastatic disease involving the thyroid gland should be actively excluded in a patient with enlarging or abnormal thyroid gland and a previously known primary tumour. We report 2 cases of primary colon carcinoma with metastasis to the thyroid gland that mimicked thyroid anaplastic carcinoma. In both cases, airway compromise was evident. Emergency tracheostomy was necessary in the first case with subsequent oxaliplatin-based chemotherapy providing palliation of symptom of breathlessness, with significant reduction in size of thyroidal metastasis. Palliative thyroidectomy relieved airway compromise in the second case. Our case report highlights the importance of early recognition of thyroidal metastases from a colonic primary as life-threatening airway compromise may otherwise rapidly ensue.

    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.)

    Although metastases to the thyroid are never uncommon at autopsy in patients who died of malignancy, metastatic thyroid carcinomas are rarely detected in clinical practice in most cases and cases of secondary thyroid cancer which require thyroid surgery clinically are few. A clinical case of thyroid metastasis from renal cell carcinoma with thyroidectomy is described herein. An 87-year-old Japanese woman was referred to us for a slow-growing palpable neck tumor with dysphagia. She had undergone a nephrectomy for renal clear cell carcinoma 19 years earlier at another hospital. Preoperative imaging examinations suspected an adenomatous goiter and a fine needle aspiration (FNA) cytology was suggestive of an atypical follicular tumor. Hemithyroidectomy was performed as a follicular tumor of thyroid for restriction of subjective symptom. A pathological examination of the thyroid tumor revealed clear cell carcinoma, postoperatively. The negative result of immunohistochemical staining for thyroglobulin also suggested metastatic renal cell carcinoma to the thyroid. Clinically significant metastases to the thyroid gland are relatively infrequent. However, if patient who bears a thyroid tumor has a history of malignancy, the possibility of metastatic disease should be taken under consideration.

    Propofol is a hypnotic agent for induction and maintainance of general anaesthesia and it is used for sedation of critically ill intensive care patients. As a rare adverse effect propofol can cause acute pancreatitis. We report a case of post-operative pancreatitis in an otherwise healthy 62-year-old male who was anaesthezised with propofol during an otherwise uncomplicated surgery for thyroid carcinoma. Other common causes could be excluded. Since this is a possible lethal complication in post-operative patients, medical doctors should be aware of this adverse effect.

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

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

    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. 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.

    2016-01-01

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

    2013-08-01

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

  6. 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.

    The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often misdiagnosed due to the more frequent branchial cyst in young people.

    Primary mucinous carcinoma of the thyroid gland is a rare disease; only 6 cases of primary mucinous carcinoma of the thyroid have been previously reported. Primary mucinous carcinoma of the thyroid gland with incomplete tumor resection tends to be associated with a poor prognosis, resulting in death within a few months. An early and appropriate diagnosis may contribute to improvement in patient prognosis; however, it is extremely difficult to diagnose primary mucinous carcinoma of the thyroid. We present the seventh reported case of primary mucinous carcinoma in the thyroid gland; moreover, rhabdoid cells were detected, which, to our knowledge, is a novel finding. An 81-year-old Japanese woman was initially diagnosed with a poorly differentiated thyroid carcinoma, and she underwent a hemithyroidectomy. Pathological examination revealed the presence of abundant mucus and agglomeration of large atypical cells. Rhabdoid cells were also seen scattered among the tumor cells. Immunostaining was performed for various markers, and on the basis of these results, we diagnosed the lesion as primary mucinous carcinoma with rhabdoid cells in the thyroid gland. Ten months after surgery, recurrence was noted in the paratracheal lymph nodes; therefore, total resection of the residual thyroid gland and paratracheal lymphadenectomy with thyroid-stimulating hormone suppression were performed. The patient is currently alive and disease-free. The current case is of interest not only because of the rare histological findings, but also because the patient achieved long-term survival following diagnosis of a mucinous carcinoma. We believe this report will be helpful for diagnosing future cases of mucinous carcinoma of the thyroid.

    Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thyroid gland and coexistent HT has not been clearly identified. We compared the clinical characteristics and disease stages of patients with primary SCC with and without lymphocytic thyroiditis (LT). We reviewed reports of primary SCC of the thyroid gland published in the English literature. We identified 46 papers that included 17 cases of primary SCC of the thyroid gland with LT and 77 cases of primary SCC of the thyroid gland without LT. Lymph node metastasis and local invasion rates did not differ between these two groups. Distant metastases were absent in patients with LT, and were observed in 13 (16.9%) patients without LT. A greater proportion of patients without LT had advanced stage disease (stage IV A-B-C) than patients with LT (p thyroid gland and coexisting LT had lower tumour-node-metastasis stage and frequency of distant metastasis than those without LT. Lymphocytic infiltration in patients with SCC appears to limit tumour growth and distant metastases.

    Radioactive iodine (RAI) ablation following thyroidectomy is recommended for most patients diagnosed with papillary and follicular thyroid carcinoma. We performed a literature search on MEDLlNE and EMBASE, using keywords, such as, differentiated thyroid carcinoma, radioiodine therapy, 131 I complications, adverse effects and side effects, and chose the most relevant studies till date to prepare this work on the side effects of RAIT (Radioactive Iodine Therapy) for thyroid cancer. We contacted authors of published studies where appropriate for further information. Also, the percentage incidence of the hazards was determined for North Indian population accessing data from Govt. Medical Colleges of Punjab, Haryana, and Postgraduate Institute of Medical Education and Research, Chandigarh. The most prominent side effect came out to be xerostomia with an incidence of 47%, followed by local neck pain and swelling (39%). The incidence of gastritis was also common (34%). Radioactive iodine therapy complications have been divided into early and late effects. Early complications include gastrointestinal symptoms, radiation thyroiditis, sialadenitis/xerostomia, bone marrow suppression, gonadal damage, dry eye, and nasolacrimal duct obstruction. Late complications include secondary cancers, pulmonary fibrosis, permanent bone marrow suppression, and genetic effects. As 131 I is an efficacious form of treatment that can significantly decrease the rate of mortality, recurrence and metastasis, and as the side effects are often minor and well-tolerated, radio iodine therapy remains the principal mode of treatment for patients.

    Papillary thyroid carcinoma is rarely associated with metastatic disease. The most common sites of metastasis are the lungs and bones, while only few cases of ovarian metastasis are described in literature. We report the case of a 51 years old woman, treated 9 years before for papillary thyroid carcinoma, presenting to our Institute with a pelvic ovarian mass revealed by ultrasound imaging. After bilateral salpingo-oophorectomy, the histologic examination detected a left ovarian metastasis from papillary thyroid carcinoma. Even if the diagnosis of ovarian metastasis from thyroid carcinoma is often controversial, it should be considered when a woman with an ovarian lesion of unknown origin, has a personal history of malignant thyroid disease.

    Seventeen cases (5 males and 12 females) of anaplastic carcinoma of the thyroid gland treated at the Department of Otolaryngology-Head and Neck Surgery, Kurume University School of Medicine, between January 1999 and January 2009 were reviewed. Ages of the patients ranged from 54 to 94 years. Six cases were treated by radical surgery. All cases were treated by radiotherapy and 5 cases received additional chemotherapy. The 6 cases treated by radical surgery were able to experience home life. Survival time of the radical surgery cases ranged from 8 to 36 months, with a median of 17 months. In cases without surgery, the survival time ranged from 1 to 8 months, with a median of 4 months. As the final outcome, only 1 case is alive after 36 months; 8 cases died by primary tumor, 7 by lung metastasis and 1 by suicide. Although the prognosis of anaplastic carcinoma of the thyroid gland is generally poor, radical surgery, if possible, may provide better survival results. (author)

    The thyroperoxidase (TPO) genetic variants in thyroid carcinoma is scarcely reported. We report on a pedigree of thyroid papillary carcinoma and hypoechoic thyroid nodules with the TPO gene mutations. The compound heterozygotic mutations of the TPO gene (c.2268-2269 insT and c.2090 G>A) in two patients with congenital goiters hypothyroidism were demonstrated. Fifteen family members of the proband and 105 control individuals were enrolled. The participants underwent clinical examination and molecular screening for TPO mutation. The hypoechoic thyroid nodules underwent fine needle aspiration biopsy. The mutation c.2268-2269 insT was detected in the four family members with normal thyroid hormone levels. The other two members harbored the c.2090 G>A mutation. The heterozygotes had degeneratively hypoechoic thyroid nodules. The control individuals showed no mutation. The maternal grandfather developed a multifocal papillary thyroid carcinoma with lymph gland and nerve invasion in the left lobe of the thyroid gland. The maternal grandfather harbored the TPO c.2268-2269 insT mutation but without BRAFV600E mutation. Malignant cells were not observed in other members by fine needle aspiration biopsy. TPO genetic variants may be associated with thyroid carcinoma and hypoechoic thyroid nodules in a few cases. Long-term follow-up in the pedigree with congenital goiter is reasonable.

    I-131 thyroid cancer therapy is based on the strategy of concentrating radioactive iodine in the thyroid tissue, to completetly eliminate thyroid tissue and functioning thyroid cancer metastases remaining after thyroidectomy. In Brazil, fixed activities of 131 I generally are given, sometimes either delivering insufficient activities to ablate all of the remnants, or unnecessarily high activities, with patients remaining in the hospital for some period of time. This investigation proposes a protocol of individualized planning of ablative doses, based on individual patients metabolisms and measured thyroid remnant masses. Simulated thyroid remnants were fabricated in various forms, volumes and activities, and optimum image acquisition parameters were determined using Single-Photon Emission Computed Tomography 9SPECT). Resultant images were evaluated, to determine the apparent volumes and the 131 I concentrations. I-131 metabolism was studied in 9 patients who had undergone thyroidectomies. Their thyroid remnant masses were determined applying the same parameters used in SPECT simulation studies, and the optimum activity for their therapy was calculated and compared to the established fixed activity of 3.7 GBq (100 mCi), which would have normally been assigned. Background subtraction using the method of percent maximum counts, using a value of 67.5%, combined with scatter correction (triple energy window method), was shown to be optimum for SPECT quantification of volumes between 3-10 ml. Errors in the method were below 9% for sources with regular geometries and around 11% for sources with irregular geometries. In the patient studies, it was observed that 78% of patients could have received reduced activities of 131 (from 0.8-3-2. GBq (20-87 nCi). In addition, 33% of these patients could have received low enough activities to have discharged from the hospital, using an individualized administration scheme. This could also have resulted in a dose reduction for many

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

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

    The 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.)

    The occurrence of a papillary thyroid carcinoma in a patient with primary hyperparathyroidism is rare. Awareness of this condition will enable clinicians to evaluate for possible thyroid pathology in patients with primary hyperparathyroidism. Both of these endocrine conditions could then be managed with a single surgery involving concomitant resection of the thyroid and parathyroid glands. We report a case of a 53-year-old woman with a parathyroid adenoma and a unilateral papillary thyroid carcinoma, and detail the clinical features, diagnosis, and management.

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.

    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

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

    The study aimed to identify the clinical characteristics of coexisting chronic lymphocytic thyroiditis (CLT) in papillary thyroid carcinoma (PTC) and to evaluate the influence on prognosis. A total of 1,357 patients who underwent thyroid surgery for PTC were included. The clinicopathological characteristics were identified. Patients who underwent total thyroidectomy (n = 597) were studied to evaluate the influence of coexistent CLT on prognosis. Among the total 1,357 patients, 359 (26.5%) had coexistent CLT. In the CLT group, the prevalence of females was higher than in the control group without CLT (P CLT were smaller than without CLT (P = 0.040, P = 0.047, respectively). Extrathyroidal extension in the patients with CLT was significantly lower than without CLT (P = 0.016). Among the subset of 597 patients, disease-free survival rate in the patients with CLT was significantly higher than without CLT (P = 0.042). However, the multivariate analysis did not reveal a negative association between CLT coexistence and recurrence. Patients with CLT display a greater female preponderance, smaller size, younger and lower extrathyroidal extension. CLT is not a significant independent negative predictive factor for recurrence, although presence of CLT indicates a reduced risk of recurrence.

    The purpose of this study was to examine the possible prognostics and clinicopathologic characteristics underlying the BRAFV600E mutation and papillary thyroid carcinoma (PTC) coexisting or in absence of chronic lymphocytic thyroiditis (CLT). This study was conducted on 172 patients who had undergone total thyroidectomy or unilateral total thyroidectomy for PTC; the patients were then examined for the BRAFV600E mutation using specimens obtained after their surgery from January 2013 to August 2015. BRAF mutations were found in 130 of 172 patients (75.6%). CLT was present in 27.9% of patients (48/172). The incidence of the BRAFV600E mutation was significantly increased in the group with no CLT (P = 0.001). The findings of the multivariate analysis pertaining to the coexistence of CLT and PTC showed no significant correlation other than the BRAFV600E mutation. No significant difference was noted in the clinicopathologic factors between the two groups based on the coexistence of CLT in univariate and multivariate analyses. The BRAFV600E mutation is less frequent in PTC coexisting with CLT presumably because CLT and the BRAFV600E mutation operate independently in the formation and progression of thyroid cancer.

    The goal of this study is to determine the clinicopathologic differences in patients with papillary thyroid carcinoma (PTC) with or without chronic lymphocytic thyroiditis (CLT). We reviewed the medical records of 195 consecutive PTC patients who underwent total thyroidectomy and bilateral central lymph node dissection from April 2008 to March 2010. The differences in clinicopathologic factors, such as age, gender, size of primary tumor, perithyroidal invasion, lymphovascular invasion, capsular invasion, and central lymph node (CLN) metastasis, were analyzed in PTC patients with or without CLT. Among 195 patients, 56 (28.7%) had co-existing CLT. Patients with CLT had the following characteristics as compared to patients without CLT: significantly younger, female predominance, smaller tumor size, and lower incidence of capsular invasion (p = 0.038, 0.006, 0.037, and 0.026, respectively). Also, patients with CLT (12.5%) had a significantly lower incidence of CLN metastases than patients without CLT (28.1%; p = 0.025) based on univariate analysis. Moreover, multivariate analysis showed that younger age (p = 0.042, odds ratio = 1.033) and female gender (p = 0.012, odds ratio = 6.865) are independent clinical factors in patients with CLT compared to patients without CLT. CLT was shown to be commonly associated with PTC. Compared to patients with PTC without CLT, patients with CLT were younger with a female predominance, which are the most important and well-known prognostic variables for thyroid cancer mortality.

    To report two cases of late metastases of clear cell renal cell carcinoma. Two patients, a male and a female with history of nephrectomy 17 and 16 years before for renal cell carcinomas, presented new tumours in the thyroid and pancreas, which were excised. Pathology reported that both lesions were clear cell tumours and immunohistochemically they were consistent with metastases from clear renal cell carcinomas. 1) Previous history of any type of carcinoma should suggest the possibility of metastases when facing a thyroid or pancreatic nodule. 2) All-life follow-up should be made, nephrectomy (resection) for a renal cell carcinoma. 3) In the presence of a clear cell tumour of the thyroid or pan-creatic glands, the differential diagnosis must always include metastatic renal cell carcinoma. 4) The treatment of choice is surgical resection.

    We wanted to evaluate the degree of conformity of papillary carcinoma and follicular carcinoma to the reported ultrasonographic findings of malignant thyroid tumor. Between January 2003 and December 2004, fine needle aspiration biopsy was performed in 1,036 patients with palpable and nonpalpable thyroid lesions. We retrospectively reviewed the ultrasonographic findings of patients with papillary carcinomas (n = 127) and follicular carcinomas (n 23) that were proven by operation or fine needle aspiration biopsy. We analyzed the ultrasonographic findings of these nodules based on the reported ultrasonographic findings of malignant thyroid tumor: hypoechogenicity, a taller than wide orientation, a microlobulated or irregular margin, a thick hypoechoic rim (halo sign), microcalcification and cystic change. The echogenicity was hypoechoic in 72.4% (92/127) of the papillary carcinomas, but it was isoechoic in 65.2% (15/23) of the follicular carcinomas (p < 0.001). The nodule shape was tall or round in 74.1% of the papillary carcinomas, but it was flat in 72.7% of the follicular carcinomas (p < 0.001). The tumor margin was microlobulated or irregular in 92.9% of the papillary carcinomas and in 60.9% of the follicular carcinomas (p < 0.001). A hypoechoic rim was seen in 26% of the papillary carcinomas (thin rim: 13.4%, thick rim: 12.6%) and in 86.6% of the follicular carcinomas (thin rim: 39.1%, thick rim: 47.8%, p < 0.001). Microcalcifications were demonstrated in 33.9% of the papillary carcinomas and in none of the cases of follicular carcinoma (p < 0.001). A solid mass without cystic change were seen in 98.4% of the papillary carcinomas and in 82.6% of the follicular carcinomas (p < 0.001). The previously reported ultrasonography findings of malignant thyroid tumor are in conformity with most of the papillary carcinomas, but not with follicular carcinomas. The current ultrasonographic features for thyroid malignancy should be cautiously applied as the indication for

    Purpose: The aim of this study is the presentation of compiled series including 142 cases of thyroid micro carcinomas observed between 1993 and 2008, the description of recurrences and the discussion of iodine 131 contribution in the therapy choices. Conclusions: Frequency of local recurrence is linked to age (under 45 years), to the size of the micro carcinoma and the presence or not of peripheral ipsilateral lymphadenectomy. In this series, all patients that had lymphadenectomy have not recurred. Bi laterality and capsular break are not causes of the recurrences. (N.C.)

    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

    Full Text Available Medullary thyroid carcinoma is a neoplasm occurring in sporadic and familial patterns. A rare variant of medullary thyroid carcinoma shows microscopic features similar to hyalinizing trabecular adenoma of thyroid. Detection of this variant requires a high index of suspicion and immunohistochemical confirmation by calcitonin positivity. We present a 36 years old female patient with a thyroid nodule, which, on microscopy, displayed an encapsulated tumor with elongated cells arranged in trabecular pattern separated by hyalinized fibrous septae simulating a hyalinizing trabecular adenoma. Also present were spindle cells arranged in an organoid fashion. Most of the cells showed salt and pepper chromatin pattern. The lesion was negative for amyloid but showed diffuse calcitonin positivity indicative of a tumor of C-cell origin i.e. medullary carcinoma of thyroid – hyalinizing trabecular variant.

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

    The radioiodine ablation therapy is required for patients who underwent a total thyroidectomy. Through a comparative review of a low iodine diet (LID) and a restricted iodine diet (RID), the study aims to suggest guidelines that are suitable for the conditions of Korea. The study was conducted with 101 patients. With 24-hour urine samples from the patients after a 2-week restricted diet and after a 4-week restricted diet, the amount of iodine in the urine was estimated. The consumed radioiodine amounts for 2 hours and 24 hours were calculated. This study was conducted with 47 LID patients and 54 RID patients. The amounts of iodine in urine, the 2-week case and 4-week case for each group showed no significant differences. The amounts of iodine in urine between the two groups were both included in the range of the criteria for radioiodine ablation therapy. Also, 2 hours and 24 hours radioiodine consumption measured after 4-week restrictive diet did not show statistical differences between two groups. A 2-week RID can be considered as a type of radioiodine ablation therapy after patients undergo a total thyroidectomy.

    Thyroid papillary carcinoma of columnar cell type is considered an uncommon histologic subtype of papillary carcinoma characterized by its morphologic features and purportedly aggressive biologic course. Sixteen cases of thyroid papillary carcinoma of columnar cell type were identified from the Endocrine Tumor Registry at the Armed Forces Institute of Pathology and the Washington Hospital Center. Clinical records and follow-up were available in all cases. Paraffin blocks were available for histochemical and immunohistochemical studies in 15 of the 16 cases. Of the 16 cases reported, 13 patients were female and 3 were male. The ages ranged from 16-76 years (average, 47 years; median, 40 years). An asymptomatic neck mass was the most common clinical presenting symptom. Macroscopically, the tumors varied from circumscribed or encapsulated to infiltrative, ranging in size from 1.5-6.5 cm. Histologically, the tumors had diverse growth patterns, including papillary, solid, microfollicular, and cribriform. A common pattern was the presence of markedly elongated follicles arranged in parallel cords. Colloid-filled follicles could be found, at least focally, in all cases. The characteristic histologic appearance included the presence of elongated cells showing nuclear stratification. Other features included the presence of vacuolated-appearing cells, spindle-shaped cells, and squamoid nests. Limited areas in the tumors showed morphologic features typical of thyroid papillary carcinoma. In 14 of the cases, the tumor was encapsulated, showed limited invasive growth, or was a microscopic tumor. In two of the cases, there was extrathyroidal invasion. Immunohistochemical studies showed consistent reactivity with cytokeratin and vimentin; varied reactivity with thyroglobulin, epithelial membrane antigen, carcinoembryonic antigen, and LeuM1; and no reactivity with calcitonin or chromogranin. Treatment was by surgical resection; supplemental radioactive iodine therapy was

    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.

    The diffuse follicular variant of papillary thyroid carcinoma (DFV-PTC) is a rare malignant thyroid condition. It represents an uncommon variant of papillary carcinoma characterized by a diffuse involvement of thyroid parenchyma, follicular architecture and nuclear features of PTC in absence of a surrounding capsule. Up to date few data have been collected about this entity and, at the best of our knowledge, only 24 cases have been reported in the literature. According to these reports DFV-PTC seems to occur preferentially in young women and shows more aggressive behavior than other papillary thyroid tumors. Herein we present an unusual case of DFV-PTC occurring in an 83 years old woman, involving the entire thyroid gland, without distinct or prevalent thyroid nodules. The tumor was clinically misdiagnosed as obstructive goiter.

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

    This is a retrospective study to evaluate the results of radiation therapy and prognostic factors influencing the results in nasopharyngeal carcinoma. From October 1989 to May 1996, 56 patients were treated for nasopharyngeal carcinoma at Department of Radiation Oncology. According to stage, patients were distributed as follows: stage I (2), II (13), III (11), IV (30). Twenty-eight patients were treated with radiation therapy and weekly CDDP. After external beam radiotherapy of 60Gy, 46 patients received boost dose with intracavitary radiation and 9 patients with 3D conformal therapy. One patient received boost dose with 2 dimensional photon beam therapy. The tumor dose ranged from 69.4Gy to 86.2Gy with median dose of 74.4Gy. The follow-up period ranged from 5 months to 92 months with a median of 34 months. Forty-seven patients achieved complete response and 8 patients showed partial response. One patient showed minimal response. Patterns of failure were as follows: locoregional recurrence (8) and distant metastasis (18). Among these patients, 2 patients failed locoregionally and distantly, The sites of distant metastasis were bone (8), lung (8) and liver (4). Five years survival rate was 67.2% and 5 years disease-free survival rate was 53.6%. KPS (P=0.005) and response of radiation therapy (P=0.0001) were significant prognostic factors for overall survival. KPS (P=0.02) and response of radiation therapy (P=0.005) were significant prognostic factors for disease-free survival. This retrospective study showed that distant metastasis was the predominant pattern of relapse in nasopharyngeal cancer. Neoadjuvant chemotherapy or weekly CDDP did not influence the distant metastasis-free survival. For advanced T stage, 3D conformal therapy provided an improved dose coverage compared to ICR. But further follow-up was needed in patients with 3D conformal therapy to assess the efficacy of this therapy. Development of techniques of radiation therapy to improve locoregional

    From 1977 through 1989, 149 patients with esophageal carcinoma were treated with external irradiation (EI) with or without high-dose rate intraluminal irradiation (HDRII) using remote afterloading system. Concerning complete response group EI alone showed higher local control rate than EI + HDRII, especially in ulcerative type. Another problem is the EI field. Fourteen of 22 patients who were salvaged by surgery due to local recurrence after EI showed marginal or out-field metastasis of the lymph node. These preliminary results suggest that HDRII is not effective for the local control of the ulcerative lesion as a boost therapy, EI should be given for the entire regional lymph nodes. (author)

The results of video-assisted thyroidectomy (VAT were evaluated in a large series of patients with papillary thyroid carcinoma (PTC, especially in terms of completeness of the surgical resection and short-to-medium term recurrence. Methods. The medical records of all patients who underwent video-assisted thyroidectomy for PTC between June 1998 and May 2009 were reviewed. Results. Three hundred fifty-nine patients were included. One hundred twenty-six patients underwent concomitant central neck node removal. Final histology showed 285 pT1, 26 pT2, and 48 pT3 PTC. Lymph node metastases were found in 27 cases. Follow-up was completed in 315 patients. Mean postoperative serum thyroglobulin level off levothyroxine was 5.4 ng/mL. Post operative ultrasonography showed no residual thyroid tissue in all the patients. Mean post-operative 131I uptake was 1.7%. One patient developed lateral neck recurrence. No other recurrence was observed.

    1976-01-01

    A patient with papillary--follicular carcinoma of the thyroid, with metastases to the lungs, skeleton, and brain, was treated 5 weeks after thyroidectomy with 135 mCi of 131 I. Although preliminary studies with 1 mCi had not shown any iodine uptake by the brain metastasis, this lesion showed intense concentration at the time of the larger therapeutic dose. Four days later, acute hemorrhage of the tumor occurred, requiring surgical removal. Although 131 I therapy would seem an unlikely cause of acute necrosis and hemorrhage in these lesions, the association of therapeutic radioiodine and hemorrhage is interesting. Since recent reports suggest that brain metastasis may be somewhat more common than previously suspected, we suggest that brain imaging be included in the workup prior to radioiodine therapy of patients with advanced metastatic disease or neurologic symptoms

    Reinhardt, M.; Moser, E.

    1995-01-01

    In the last decade, several concepts were developed to improve the outcome of radioiodine therapy for functional thyroid autonomy. These concepts base on Marinellis' formula, which enables for individual dose determination. Each concept is good for an overall success rate between 75-100% and a less than 10% rate of post-treatment hypothyroidism but reveals different problems in its clinical application. Fractionated radioiodine treatment requires often two or more doses, which may delay the final success until two years. The standard concept using a high level target dose of 400 Gy requires accurate determination of the target or autonomous volume. Applied to multiple foci, target volume becomes often overestimated and hypothyroidism after treatment may arise accordingly. The so-called 'dosimetric compromise' foregoes determination of the autonomous volume, using the total thyroid gland as target volume and reducing the accordingly target dose to 150 Gy. This concept gives best results for patients with TcTU s s -level prior to radioiodine treatment. (orig./MG) [de

    The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often misdiagnosed due to the more frequent branchial cyst in young people. Although oronasopharyngeal squamous cell carcinoma has been reported as the main cause of lymph neck node metastasis, thyroid papillary carcinoma may be responsible for solitary cervical cystic masses as the initial manifestation of the disease. This situation has been rarely reported, although solid masses are much more frequent. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland. We present a rare case of solitary cystic lymph node metastasis of occult papillary carcinoma of the thyroid. We also discuss possible etiology for thyroid papillary carcinoma in lateral neck cysts.

    Human undifferentiated thyroid carcinoma (UTC) is a very aggressive tumor which lacks an adequate treatment. The UTC human cell line ARO has a selective uptake of BPA in vitro and after transplanting into nude mice. Applications of boron neutron capture therapy (BNCT) to mice showed a 100% control of growth and a 50% histological cure of tumors with an initial volume of 50 mm 3 or less. As a further step towards the potential application in humans we have performed the present studies. Four dogs with diagnosis of spontaneous UTC were studied. A BPA-fructose solution was infused during 60 min and dogs were submitted to thyroidectomy. Samples of blood and from different areas of the tumors (and in one dog from normal thyroid) were obtained and the boron was determined by ICP-OES. Selective BPA uptake by the tumor was found in all animals, the tumor/blood ratios ranged between 2.02 and 3.76, while the tumor/normal thyroid ratio was 6.78. Individual samples had tumor/blood ratios between 8.36 and 0.33. These ratios were related to the two histological patterns observed: homogeneous and heterogeneous tumors. We confirm the selective uptake of BPA by spontaneous UTC in dogs and plan to apply BNCT in the future

    Postoperative follow-up study of patients with differentiated thyroid carcinoma (DTC) is currently based on periodic whole body scan (WBS) and serum thyroglobulin (Tg) assessment. The correlation between Tg levels measured and WB scans of 84 DTC patients is investigated. WBS are performed on a rotation gamma camera DIACAM (Siemens) at 48 and 72 hours after per os administration of 185-222 MBq 131 I. The levels of Tg are determined by IRMA method and kits of BYK, Germany. Normal Tg values are obtained at a control group of 27 patients free of thyroid disease. Increased Tg levels are found at 2 cases (4%) of the group of 50 patients with total thyroidectomy given 131 I without any evidence of recurrences or metastases. At the third group consisting of 18 patients with total thyroidectomy, following 131 I therapy and recurrences and/or metastases, increased Tg values were obtained in 8 cases or 44.4%. Also increased Tg levels were obtained at 4 from 16 patients (25%) subjected to total thyroidectomy but with a residual thyroid tissue proved by scintigraphy. In conclusion, a combination of both methods should be applied for improving the diagnostic and therapeutic results at the postoperative control of DTC patients

    Full Text Available INTRODUCTION: A less extensive thyroidectomy could be used for patients in the low risk group.OBJECTIVE: To perform a critical follow-up after lobectomy with isthmusectomy for the treatment of papillary thyroid carcinoma in patients with a single nodule limited to the periphery of the lobe.METHODS: Thirty-one patients with thyroid papillary carcinoma operated on till 1993 were selected. They had undergone lobectomy with isthmusectomy. This is a retrospective cohort study in which the oncological outcome (contralateral and regional recurrence and the reoperation complications (recurrent nerve paralysis/paresis and hypoparathyroidism were evaluated. Descriptive analysis was employed.RESULTS: In the last decade (2003-2013, 6 (20% contralateral recurrences were observed in the remaining lobe and in 1 of these cases (3%, contralateral lymph node metastases were noted. A completion thyroidectomy plus lymphadenectomy was performed, without modification of global survival.CONCLUSION: Because of the rate of 20% of contralateral recurrence after a 20-year follow-up, we suggest modification of the surgical paradigm for total thyroidectomy as an initial therapy.

    Most patients with newly diagnosed differentiated thyroid carcinoma have tumors with low risk of mortality and recurrence. Standard therapy has been total or near total thyroidectomy followed by postoperative radioiodine remnant ablation (RRA). Although RRA provides benefits, current clinical guidelines do not recommend it universally, since an increase in disease-free survival or a decrease in mortality in low risk patients has not been demonstrated so far. Advancements in our understanding of the biological behavior of thyroid cancer have been translated into the clinic in a personalized approach to the patients based on their individual risk of recurrence and mortality. Current evidence suggests that RRA is not indicated in most low-risk patients, especially those with papillary carcinomas smaller than 1cm, without extrathyroidal extension, unfavorable histology, lymph node involvement or distant metastases. Follow-up of these patients with serial measurements of serum thyroglobulin and neck ultrasound is adequate. Careful evaluation of all risk factors of clinical relevance will allow a more realistic assessment of each individual patient. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

  18. Thyroid-Specific Genes Expression Uncovered Age-Related Differences in Pediatric Thyroid Carcinomas

    2016-01-01

    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.

    Carcinoma of the endometrium is the most common malignant tumor in the female genital tract. Radiation therapy continues to play a major role in the management of endometrial carcinoma, both as primary therapy and as adjuvant treatment. The utility of pelvic external beam therapy and intracavitary therapy is long established. However, the modern era of surgical staging has lead to an appreciation of the role of radiation therapy beyond the pelvis. Radiation therapy has been shown to be of particular benefit in peritoneal and nodal spread. The classic management of endometrial cancer is reviewed and relatively new and somewhat controversial topics, such as preoperative intracavitary therapy followed by external beam therapy are discussed

    To assess the clinical value of treatment with 131 I for brain metastases from differentiated thyroid cancer (DTC), the authors have observed 8 cases of brain metastases from DTC who received follow-up after 131 I therapy (2 male, 6 female, aged 12-65 years). The results of 131 I 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 131 I therapy were clearly decreased for the cases with total thyroidectomy in comparison with those with semithyroidectomy (p 131 I for brain metastases from DTC after undergoing thyroidectomy may improve clinical symptoms and lift quality, reduce lesions, and prolong survival.

    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 X 2 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 (P 0.05). 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

  3. The Effect of High Dose Radioiodine Therapy on Formation of Radiation Retinopathy During Thyroid Cancer Treatment

    2014-10-01

    Full Text Available Objective: Non-thyroidal complication of high-dose radioiodine therapy for thyroid carcinoma might cause salivary and lacrimal gland dysfunction, which may be transient or permanent in a dose-dependent manner. However, radiation retinopathy complicating 131I therapy, has not been previously well characterized. The aim of this study was to evaluate the extent of retinal damage among patients who had received high doses of radioiodine treatment. Methods: Forty eyes of 20 patients (3 male, 17 female who received 250-1000 mCi during 131I therapy and on ophthalmological follow up for a year after the last treatment were included in the study. Mean age of the study group was 50 years (range 25-70 years. In ophthalmologic examination, visual acuity was measured in order to determine visual loss. Intraocular pressure was measured in all the patients. Then lens examination was carried out with slit lamp biomicroscopy in order to investigate cataract or partial lens opacities. Fundus observation was carried out through the dilated pupil with slit lamp biomicroscopy using 90 D noncontact lens. Result: The best corrected visual aquity with Snellen chart was found as 1.0 in 36 eyes (90% and between 0.6 and 0.9 (10% in 4 eyes (10%. At the biomicroscopic fundus examination, retinal hemorrhage consistent with radiation retinopathy, microaneurysm, microinfarction, edema or exudation, vitreus hemorrhage, partial or total optical disc pallor indicating papillopathy in the optic disc were not observed in any of the eyes. Conclusion: This result indicates that there is not any significant correlation between repeated high-dose radioiodine therapy and radiation retinopathy in differentiated thyroid carcinomas. Even though there is not a significant restriction in use of higher doses of radioiodine therapy in differentiated thyroid carcinoma, more extensive studies are needed in order to obtain more accurate data on possible occurrence of retinopathy.

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

    Between 1971-1989, 59 patients received external radiation therapy with a curative intent. There were 25 females and 34 males, ranging in age from 19 to 87. No patient had distant metastases at the onset of treatment. The majority had a total thyroidectomy (55/59), generally combined with neck dissection. Residual tumor was left in 11 cases, and 44 had positive cervical nodes. Using megavoltage radiotherapy, the whole neck and upper mediastinum area were most often irradiated through a large anterior Y-shaped field without laryngeal shielding. The mean dose to the tumoral bed was 54 Gy. Dysphagia was observed in 32 patients (11, 17 and 5 scores were grade 1, 2 and 3 respectively). Dyspnea occurred in 5 cases and in 2 of these, it was considered to be severe. Local recurrences were noted in 19 (30%) patients, most of them occurring within the fields of irradiation. Parameters such as age, sex, total dose, irradiated volumes or cervical node enlargement did not modify local control rate. Same conclusions can be drawn for distant failures. Thirty-five patients are still alive and among them, 24 have no evidence of disease. Average length of survival is 70.5 months and is shortened by the occurrence of distant failures except in patients with bone metastases. (author). 13 refs.; 1 fig.; 6 tabs.

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

    Thyroid hormone producing thyroid carcinoma is an uncommon cause of thyrotoxicosis. A patient with extensive hepatic metastases from well-differentiated carcinoma is presented. Administration of amiodarone for atrial fibrillation led to the development of hyperthyroidism. Precipitation of thyrotoxicosis by iodine-containing compounds in patients with thyroid carcinoma is rare. The relatively high iodine load and the slow elimination of amiodarone complicate the clinical management of such patients.

    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. © 2016 Society for Endocrinology.

    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: φ8.2 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.

    We present a case of a postmenopausal woman diagnosed with an ovarian mass containing thyroid follicles and foci of papillary thyroid carcinoma during pathological examination. This patient referred having had a metachronous thyroid malignancy 10 years before. The differential diagnosis between a thyroid malignancy arising from a struma ovarii and a metastatic ovarian tumor originating from thyroid-cancer is challenging. Struma ovarii should be considered when thyroid components are the predominant element or when thyroid malignant tissue is identified within an ovarian lesion. Thyroid carcinoma arising from a struma ovarii is reported to occur in a minority of cases. Of these, papillary carcinoma is the most frequent subtype encountered. Regarding primary thyroid carcinomas, papillary carcinomas have a lower metastatic potential when compared to follicular carcinomas, and most of the metastases occur in the cervical lymph nodes. Ovarian metastases are exceedingly rare and generally associated with widespread disease. However, they must be considered in the presence of previous history of malignant thyroid carcinoma. The authors review the main clinical, imaging and therapeutic aspects of both these entities and present the most likely diagnosis.

    The therapy of unresectable advanced thyroid carcinomas shows unfavorable outcome. Constitutive nuclear factor-κB (NF-κB) activation in thyroid carcinomas frequently contributes to therapeutic resistance; the radioiodine therapy often fails due to the loss of differentiated functions in advanced thyroid carcinomas. Curcumin is known for its anticancer properties in a series of cancers, but only few studies have focused on thyroid cancer. Our aim was to evaluate curcumin's molecular mechanisms and to estimate if curcumin could be a new therapeutic option in advanced thyroid cancer. Human thyroid cancer cell lines TPC-1 (papillary), FTC-133 (follicular), and BHT-101 (anaplastic) were treated with curcumin. Using real-time PCR analysis, we investigated microRNA (miRNA) and mRNA expression levels. Cell cycle, Annexin V/PI staining, and caspase-3 activity analysis were performed to detect apoptosis. NF-κB p65 activity and cell proliferation were analyzed using appropriate ELISA-based colorimetric assay kits. Treatment with 50 μM curcumin significantly increased the mRNA expression of the differentiation genes thyroglobulin (TG) and sodium iodide symporter (NIS) in all three cell lines and induced inhibition of cell proliferation, apoptosis, and decrease of NF-κB p65 activity. The miRNA expression analyses showed a significant deregulation of miRNA-200c, -21, -let7c, -26a, and -125b, known to regulate cell differentiation and tumor progression. Curcumin arrested cell growth at the G2/M phase. Curcumin increases the expression of redifferentiation markers and induces G2/M arrest, apoptosis, and downregulation of NF-κB activity in thyroid carcinoma cells. Thus, curcumin appears to be a promising agent to overcome resistance to the conventional cancer therapy.

    MINI: A 3D printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma. The personalized porous implant printed in Ti6AL4V provided excellent physicochemical properties and biological performance, including biocompatibility, osteogenic activity, and bone ingrowth effect. A unique case report. A three-dimensional (3D) printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma in a middle-age female patient. Papillary thyroid carcinoma is a malignant neoplasm with a relatively favorable prognosis. A metastatic lesion in multilevel cervical spine (C2-C4) destroys neurological functions and causes local instability. Radical excision of the metastasis and reconstruction of the cervical vertebrae sequence conforms with therapeutic principles, whereas the special-shaped multilevel upper-cervical spine requires personalized implants. 3D printing is an additive manufacturing technology that produces personalized products by accurately layering material under digital model control via a computer. Reporting of this recent technology for reconstructing multilevel cervical spine (C2-C4) is rare in the literature. Anterior-posterior surgery was performed in one stage. Radical resection of the metastatic lesion (C2-C4) and thyroid gland, along with insertion of a personalized implant manufactured by 3D printing technology, were performed to rebuild the cervical spine sequences. The porous implant was printed in Ti6AL4V with perfect physicochemical properties and biological performance, such as biocompatibility and osteogenic activity. Finally, lateral mass screw fixation was performed via a posterior approach. Patient neurological function gradually improved after the surgery. The patient received 11/17 on the Japanese Orthopedic Association scale and ambulated with a personalized skull-neck-thorax orthosis on

    The effects of radiation on the thyroid were investigated in 102 patients treated by radiation therapy to the neck. All patients had radiation ports which included the thyroid gland. Serum thyroid stimulating hormone (TSH) levels were elevated in 41 cases and the cumulative elevation rate was 52.1% in 5 years. The high frequency of elevated serum TSH levels observed in patients whose thyroid glands were included within the radiation fields (74.1%) was statistically significant compared to those whose thyroid glands were only partially included (23.4%). Among the patients whose entire thyroid glands were included within the radiation field, combination with chemotherapy increased the frequency of elevated serum TSH levels, but the increase was not statistically significant. Among 36 laryngeal cancer patients treated by only radiation therapy through a portal encompassing part of the thyroid, 4 (14%) were found to have elevated serum TSH levels. We advocate routine monitoring of thyroid functions after radiation therapy to the neck. (author)

    Papillary thyroid carcinoma (PTC) is a rare childhood disease. The development of PTC in dyshormonogenetic congenital hypothyroidism (CH) is infrequent, with very few case reports in literature. To report a case of PTC in a boy with dyshormonogenetic CH without goitre and exposed to ionising radiation. To evaluate relationships between these factors and development of PTC. We present a boy with dyshormonogenetic CH since birth. Early hormonal substitution was initiated, with subsequent normal levels of thyrotropin and thyroid hormones. He has also congenital cardiomyopathy, exposed to interventional treatment with 10 heart catheterisations, and approximately 26 chest X-rays at paediatric doses. A thyroid nodule was found in thyroid echography at the age of 6 years old. Fine needle aspiration biopsy confirmed high probability of thyroid carcinoma (Bethesda 5). The pre-surgical thorax and cerebral scan showed no evidence of metastasis. The patient underwent total thyroidectomy. Pathological examination revealed a 0.5cm papillary thyroid micro-carcinoma in the right lobe, with no evidence of dissemination. Genetic mutations and radiation exposure may play an important role in the development of PTC. There may be common pathways between dyshormonogenetic CH and thyroid carcinoma that need further investigation. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U.

    Full Text Available Objective: The objective of this study was to optimize dose of levothyroxine (LT4 based on lean body mass (LBM in young athyrotic patients with differentiated carcinoma of thyroid (DCT which has not been properly addressed in Bangladesh before. Materials and Methods: Sixty patients with DCT (age, range: 20-39 years having total thyroidectomy followed by radioiodine ablative therapy (RIT and 23 euthyroid volunteers were recruited. Clinical, biochemical parameters were obtained from all patients after 2 months of RIT and on LT4 replacement at a dose of 200 μg/day as first follow up visit and also from control subjects. Then 60 patients were divided into two groups consisting of 30 patients each. Patients of Group-I received LT4 replacement based on LBM measured by dual energy X-ray absorptiometry (DXA and Group-II continued LT4 replacement in conventional dose. Patients of both groups were assessed again for same parameters at 6 to 12 months at the second visit. Results: Optimized dose of LT4 based on LBM by DXA (131 ±23 μg/day significantly reduced thyroid hormones and kept thyroid stimulating hormone (TSH in expected levels in patients of Group-I at the second visit compared to patients of Group-II who continued conventional LT4 dose (200 μg/day. Hyperthyroid symptom scale (HSS was significantly reduced to 2 ± 1 in patients of Group-I but not in patients of Group-II, HSS, 8 ±1 ( P < 0.001. Conclusion: Optimization of LT4 dose based on LBM can avoid chronic exposure of mild excess of thyroid hormone in young patients with low risk DCT.

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

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

  3. Carcinoma Showing Thymus-Like Differentiation (CASTLE of Thyroid: A Case Report and Literature Review

    2008-11-01

    Full Text Available Carcinoma showing thymus-like differentiation (CASTLE is a rare malignant neoplasm that occurs in the thyroid gland, or head and neck. This tumor arises from either ectopic thymus tissue or remnants of branchial pouches, which retain the potential to differentiate along the thymus line. Clinical presentation and imaging can be consistent with a malignant lesion such as thyroid cancer or thymic carcinoma. Immunohistochemical staining with CD5 can differentiate CASTLE from other malignant thyroid neoplasms. A 54-year-old male had initially presented with a painless, left neck mass for 3 months. He underwent left thyroid lobectomy via a median sternotomy approach. Carcinoma showing thymus-like differentiation was the final histopathologic diagnosis. After 36 months of follow-up, no evidence of recurrence was observed. A median sternotomy is an excellent approach for CASTLE with anterior mediastinum involvement. Complete resection is important to improve the long-term survival rate and the locoregional recurrence rate.

    After a slow start in late sixties, the procedure of 131 I therapy for Differentiated Thyroid Cancer (DTC) has gained increasing popularity with every passing year at All India Institute of Medical Sciences. This has become an integral part of TC management at AIIMS like at most other centres all over the world. There is a general consensus that near total thyroidectomy along with 131 I therapy and suppressive doses of thyroid hormones provide the best mode of treatment for DTC

    The differentiated thyroid carcinoma (DTC), constitutes the 90 % of the thyroid gland cancers. 80% of patients are cured after the initial therapy and 12% remained disease-free after successive treatments. The 24 patients included in this study represent a sample of the aforementioned 12% and 8%, with recurrence in the first decade post-treatment (local disease and/or recurrence at distance). The internal radiotherapy with 131 I in patients with DTC is used within the therapeutic schema as a step post-thyroidectomy. The success of the therapy is to get a lethal dose in the tumor tissue, which depends on the therapeutic activity and the retention of 131 I, without exceeding the dose of tolerance in healthy tissues. The most widespread way of administration is the empirical prescription which considers the clinical and laboratory parameters for its determination. In this work, the treatment protocol applied incorporates assessment by biological (DB) and internal (DI) dosimetry for estimating absorbed dose to the whole body and bone marrow to manage a personalized therapeutic dose for each patient. The biological dose estimation is based on the quantification of chromosomal aberrations, which is often referred to a dose-response curve in which lymphocytes are irradiated in vitro with 131 I, allowing to determine the dose in vivo of circulating lymphocytes patients [es

    Medullary thyroid carcinoma (MTC), a rare calcitonin-producing tumor, is derived from parafollicular C-cells of the thyroid and is characterized by constitutive Bcl-2 overexpression. The tumor is relatively insensitive to radiation therapy as well as conventional chemotherapy. To date, the only curative treatment is the early and complete surgical removal of all neoplastic tissue. In this study, the antiproliferative and pro-apoptotic effects of fractions obtained from Uncaria tomentosa (Willd.) DC, commonly known as uña de gato or cat's claw were investigated. Cell growth of MTC cells as well as enzymatic activity of mitochondrial dehydrogenase was markedly inhibited after treatment with different fractions of the plant. Furthermore, there was an increase in the expressions of caspase-3 and -7 and poly(ADP-ribose) polymerase (PARP) fraction, while bcl-2 overexpression remained constant. In particular, the alkaloids isopterpodine and pteropodine of U. tomentosa exhibited a significant pro-apoptotic effect on MTC cells, whereas the alkaloid-poor fraction inhibited cell proliferation but did not show any pro-apoptotic effects. These promising results indicate the growth-restraining and apoptotic potential of plant extracts against neuroendocrine tumors, which may add to existing therapies for cancer.

    The follow-up of patients with differentiated thyroid carcinoma is based on guidelines of the appropriate scientific societies like the German Society of Nuclear Medicine (DGN). After (successfull) radioiodine treatment there are follow-up investigations in intervalls (every [half] year, life-long) including ultrasound, serum level of thyroglobulin, TSH, (f)T3, and (f)T4. If recurrent/metastatic disease is suspected further special methods will follow (radioiodine scan, CT, MRI..). 5- and 10-year overall survival rates of paillary carcinoma are in the range of 90% and 80%, of follicular carcinoma in the range of 80% and 70%, respectively. Individual prognosis can be assessed by different scoring systems including factors like age, sex, size, grading, and extent of the disease. The medullary carcinoma has a mediocre prognosis and similar follow-up intervals focusing on the tumor markers calcitonin and CEA and, if necessary, a variety of imaging methods. The anaplastic carcinoma with its bad prognosis needs individual (palliative) symptomatic follow-up. (orig.) [German] Die Nachsorge des differenzierten Schilddruesenkarzinoms orientiert sich an Empfehlungen und Leitlinien der DGN sowie weiterer Fachgesellschaften. Nach (erfolgreicher) Therapie sind in Intervallen (1/2jaehrlich, jaehrlich, lebenslang) ambulante Nachsorgeuntersuchungen mit Sonographie, Thyreoglobulin- und TSH-, [f]T3-, [f]T4-Bestimmung erforderlich. Je nach Rezidiv-/Metastasenverdacht sind gezielte weitere Untersuchungen durchzufuehren (Radiojoddiagnostik, CT, MRT...). Die 5- und 10-Jahres-Ueberlebensraten des papillaeren Karzinoms liegen um 90% bzw. 80%, die des follikulaeren um 80% bzw. 70%. Die Prognose kann mittels diverser Scores bestimmt werden, die u.a. Alter, Geschlecht, Grading, und Ausdehnung der Erkrankung beruecksichtigen. Das medullaere Karzinom hat bei mittlerer Prognose aehnliche Nachsorgeintervalle, orientiert sich an den Tumormarkern Kalzitonin und CEA und gegebenenfalls komplexer

    Full Text Available Shear wave elastography (SWE is a modern method for the assessment of tissue stiffness. There has been a growing interest in the use of this technique for characterizing thyroid focal lesions, including preoperative diagnostics. Aim: The aim of the study was to assess the clinical usefulness of SWE in medullary thyroid carcinoma (MTC diagnostics. Materials and methods: A total of 169 focal lesions were identifi ed in the study group (139 patients, including 6 MTCs in 4 patients (mean age: 45 years. B-mode ultrasound and SWE were performed using Aixplorer (SuperSonic, Aix-en-Provence, with a 4–15 MHz linear probe. The ultrasound was performed to assess the echogenicity and echostructure of the lesions, their margin, the halo sign, the height/width ratio (H/W ratio, the presence of calcifi cations and the vascularization pattern. This was followed by an analysis of maximum and mean Young’s (E modulus values for MTC (EmaxLR, EmeanLR and the surrounding thyroid tissues (EmaxSR, EmeanSR, as well as mean E-values (EmeanLRz for 2 mm region of interest in the stiffest zone of the lesion. The lesions were subject to pathological and/or cytological evaluation. Results: The B-mode assessment showed that all MTCs were hypoechogenic, with no halo sign, and they contained micro- and/ or macrocalcifi cations. Ill-defi ned lesion margin were found in 4 out of 6 cancers; 4 out of 6 cancers had a H/W ratio > 1. Heterogeneous echostructure and type III vascularity were found in 5 out of 6 lesions. In the SWE, the mean value of EmaxLR for all of the MTCs was 89.5 kPa and (the mean value of EmaxSR for all surrounding tissues was 39.7 kPa Mean values of EmeanLR and EmeanSR were 34.7 kPa and 24.4 kPa, respectively. The mean value of EmeanLRz was 49.2 kPa. Conclusions: SWE showed MTCs as stiffer lesions compared to the surrounding tissues. The lesions were qualifi ed for fi ne needle aspiration biopsy based on B-mode assessment. However, the diagnostic algorithm

    Young patients carriers differentiated thyroid carcinoma (DTC) are treated with high doses of I-131 for much of his life with very good prognosis and projects with paternity. However, there is scarce information on the effect of radioiodine on the male gonad and their future fertility. This therapy may compromise on a temporary and / or definitively the role of the germinal cells. The testicular irradiation depends on the blood flow, the dose of I-131 administered and of the presence or absence of metastasis pelvic near to the gonads. A single dose of 100 mCi of I-131 throws an absorbed dose at gonadal level of 50-150 cGy. It has been reported that absorbed doses of 50 cGy can produce transitory decrease spermatogenesis and higher doses can also affect the function of the Leydig cells [es

    2013-01-01

    Full Text Available Clear cell renal cell carcinoma (CCRCC is the most common origin for metastasis in the thyroid. A 51-year-old woman was referred to our hospital for a subcarinal lesion. Ten years before, the patient had undergone a nephrectomy for CCRCC. Whole-body fluorodeoxyglucose positron emission tomography revealed elevated values in the thyroid gland, while the mediastinum was normal. An endoscopic ultrasonography-guided fine-needle aspiration biopsy of the mediastinal mass was consistent with CCRCC, and this was confirmed after resection. The thyroidectomy specimen also revealed lymphocytic thyroiditis, nodular hyperplasia, one follicular adenoma, two papillary microcarcinomas, and six foci of metastatic CCRCC involving both thyroid lobes. Curiously two of the six metastatic foci were located inside two adenomatoid nodules (tumor-in-tumor. The metastatic cells were positive for cytokeratins, CD10, epidermal growth factor receptor, and vascular endothelial growth factor receptor 2. No BRAF gene mutations were found in any of the primary and metastatic lesions. The patient was treated with sunitinib and finally died due to CCRCC distant metastases 6 years after the thyroidectomy. In CCRCC patients, a particularly prolonged survival rate may be achieved with the appropriate therapy, in contrast to the ominous prognosis typically found in patients with thyroid metastases from other origins.

    Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves' disease were compared to those with multinodular goiter. Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves' disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Early stage thyroid cancer has better survival and prognosis after surgical treatment. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cytology. We excluded 65 cases because of preoperative diagnosis of thyroid cancer, and 68 because of nonincidental cancer within the index nodule. Among the remaining 580 cases, there were 43 cases (7.4%) of incidental thyroid cancers. Incidental thyroid cancers were significantly associated with moderate/severe lymphocytic thyroiditis (relative risk = 2.5; p = .03). Sixteen of 56 patients with moderate/severe lymphocytic thyroiditis had Graves' disease, none of whom had incidental thyroid cancer. The risk of incidental thyroid cancer associated with moderate/severe lymphocytic thyroiditis was significantly higher in non-Graves' than patients with Graves' disease (p = .05). The risk of incidental thyroid cancer is significantly increased in patients with moderate/severe lymphocytic thyroiditis. Moderate/severe lymphocytic thyroiditis associated with Graves' disease seems to have a lower risk of incidental thyroid cancer. © 2016 Wiley Periodicals, Inc.

    The goal of the study was to determine the role of routine total thyroidectomy and hemithyroidectomy in patients undergoing total laryngectomy for laryngeal squamous cell carcinoma. The study group consisted of 343 patients who underwent total laryngectomy (98 treated with surgery alone, 136 treated following radiation failure, and 109 following chemoradiation failure). Total thyroidectomy was performed in all obstructing and bilateral lesions or if there was suspicion of contralateral lobe involvement. Hemithyroidectomy was performed in all lateralized lesions. Retrospective histopathologic analysis of thyroid specimens was subsequently performed. In all, 262 patients underwent total thyroidectomy during total laryngectomy, six of which demonstrated squamous cell carcinoma evident within the thyroid gland (4 from transglottic lesions, 2 from subglottic lesions). Hemithyroidectomy was performed in 81 patients, with only one patient demonstrating evidence of squamous cell carcinoma within the thyroid gland. Hypothyroidism was observed in 88% (n = 61) of patients who underwent thyroid lobectomy alone, requiring hormone supplementation. Routine surgical management of the thyroid gland should not be performed, except in cases of subglottic primary lesions, lesions with significant subglottic extension, or transglottic lesions. Despite efforts to preserve the contralateral thyroid lobe in cases of selective lobectomy, these patients often have a high rate of hypothyroidism, and a total thyroidectomy should be considered when involvement of the thyroid gland is suspected.

    To evaluate the applicability of ultrasound (US)-based Thyroid Imaging Reporting and Data System (TI-RADS) for evaluating medullary thyroid carcinoma (MTC). US images and medical records of patients with cytopathology-confirmed MTC between June 2003 and November 2016 were retrospectively reviewed. Four independent reviewers (two experienced and two inexperienced radiologists) evaluated 57 pre-operative US images of patients with MTC for shape, composition, echogenicity, margin, calcification of the MTC nodules, and categorized the nodules using TI-RADS classification. Weighted Kappa statistics was used to determine the inter-observer agreement of TI-RADS. Univariate and multivariate analyses were performed to assess US findings associated with lymph node metastasis. Ninety-five percent of nodules were classified as either high suspicion (68%) or intermediate suspicion (26%). The overall inter-rater agreement was good (Kappa 0.84, agreement 91.52%), and inexperienced reviewers also showed good agreements with the most experienced reviewer (weighted Kappa 0.73 and 0.81). According to the univariate analysis, TI-RADS category 5, shape, microcalcification, and extrathyroid extension were significantly associated with lymph node metastasis in MTC patients (p = 0.003, 0.008, 0.001, and 0.021, respectively). As per the multivariate analysis, the presence of microcalcification and the irregular shape of the nodule were significantly associated with metastatic lymph nodes in MTC patients (odds ratio, 26.6; 95% CI, 2.7-263.7, p = 0.005, odds ratio, 14.7; 95% CI, 1.3-170, p = 0.031, respectively). TI-RADS is applicable for the evaluation of MTC nodules with good inter-observer agreement.

    The thyroid gland is a rare site of clinically detectable tumor metastasis. As thyroid tumors are usually assumed to be primary in origin, its recognition as a secondary is difficult. We report a case of an 80-year old female who was referred to the Department of Surgery for a symptomatic thyroid nodule. Her medical history included a radical nephrectomy for renal cell carcinoma (RCC) nine years ago. During follow-up a pancreatic nodule was noted suggestive of a neuroendocrine tumor and the von Hippel-Lindau syndrome had to be ruled out. The fine-needle aspiration biopsy (FNAB) guided by ultrasound (US) of the thyroid nodule was inconclusive and a hemithyroidectomy and isthmectomy were performed. Histological examination revealed metastasis of a clear cell carcinoma. RCC disseminates in an unpredictable manner and can show late recurrences. Although secondary involvement of the thyroid gland by RCC is rare, it is still one of the more common neoplasms to metastasize to this site. There are no specific clinical features and few characteristic findings of metastatic thyroid carcinoma on imaging studies. FNAB is a useful procedure to diagnose metastatic thyroid cancer, but one should remain suspicious when the result for malignant cells is negative or indeterminate. After thyroidectomy the diagnosis of RCC is confirmed immunohistochemically. There is a clear survival benefit if a surgical approach to the thyroid metastasis is chosen. Thyroid metastasis should be considered in patients with a thyroid nodule and positive history for RCC. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    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.

    In a retrospective study we evaluated the data of 112 patients who underwent radioiodine treatment for functional autonomy of the thyroid at Essen University Hospital from 1988 to 1993. Therapeutic activities of radioiodine were administered after individual determination of activity for intended radiation doses (150-300 Gy) taking into consideration autonomously functioning volume, maximum uptake, and effective half-life. The achieved dose was calculated by means of measurement of the radioiodine kinetics during therapy. Depending on the type of autonomous function of the thyroid (solitary autonomously functioning nodule, multiple autonomously functioning nodules, autonomously functioning thyroid tissue) volume reductions between 39 and 46% were found approximately 6 months after treatment.

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

    Purpose: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. Aim: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. Material and results: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. Conclusion: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to

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

    Hürthle cell carcinoma (HCC) is an uncommon thyroid cancer historically considered to be a variant of follicular thyroid carcinoma (FTC). The aim of this study was to assess the differences between these groups in terms of clinical factors and prognoses. A total of 230 patients (153 with FTC and 77 with HCC) with a median follow-up of 13.4 years were studied. The different characteristics were compared using SPSS version 20 statistical software. Patients with HCC were older (57.3±13.8 years vs. 44.6±15.2 years; P<.001). More advanced TNM stages were also seen in patients with HCC and a greater trend to distant metastases were also seen in patients with HCC (7.8% vs. 2.7%, P=.078). The persistence/recurrence rate at the end of follow-up was higher in patients with HCC (13% vs. 3.9%, P=.011). However, in a multivariate analysis, only age (hazard ratio [HR] 1.10, confidence interval [CI] 1.04-1.17; P=.001), size (HR 1.43, CI 1.05-1.94; P=.021), and histological subtype (HR 9.79, CI 2.35-40.81; P=.002), but not presence of HCC, were significantly associated to prognosis. HCC is diagnosed in older patients and in more advanced stages as compared to FTC. However, when age, size, and histological subtype are similar, disease-free survival is also similar in both groups.

    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.

    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.

    To determine the carcinogenic effects of diagnostic amounts of radioactive iodine-131 on the infantile thyroid gland a multi-center retrospective cohort study was conducted which included data of 4973 subjects who had either been referred to diagnostic iodine-131 uptake tests (2262 subjects) or had had a diagnostic procedure of the thyroid without 131-iodine (2711 subjects) until the age of 18 years. Follow-up examinations of 35 percent of the subjects in the iodine-131 group and 41 percent of the subjects in the control group took place after a mean time period of 20 years after the first examination. Dosimetry of the thyroid burden of iodine-131 was carried out according to ICRP 53. The median of the thyroid organ dose was 1012 mGy. The report compares prevalences or incidences of thyroid disorders resp. occurring in both groups and gives a stratified analysis of primary diagnosis, age at exposure, and organ dose. A total number of five carcinomas of the thyroid was found. In the radioiodine group two carcinomas were assessed in a period of 16500 person-years. The control group yielded three carcinomas over 21000 person-years (Relative rate: 0,89, 95% confidence interval: 0,14-5,13). (orig.) [de

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

    The diagnostic value of thyroglobulin (hTg) serum measurements for the follow-up of papillary, follicular and oncocytic thyroid carcinoma has been re-evaluated after more than 6 years of clinical experience with this tumor marker in 370 cancer patients. The sensitivity of hTg RIA for the detection of metastases or recurrence amounts to 94%, provided that residual thyroid tissue has been totally ablated and that serum samples are drawn after withdrawal of thyroid hormone replacement. The I-131 scan may be replaced under certain conditions by hTg RIA which has proven a valid, reasonable and convenient diagnostic method for long time follow-up of differentiated thyroid cancer. The somewhat reduced sensitivity of hTg determinations under continued thyroid hormone medication can be tolerated, provided that a standardised follow-up protocol is used including clinical, sonographic and radiological investigations.

    Breast metastases are a relatively rare condition and account for approximately 0.5-2% of all breast tumors. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary tumor. Breast metastases from medullary thyroid cancer (MTC) are very rare with only 21 reported cases in the literature. Some MTCs mimic primary invasive lobular carcinoma of the breast histopathologically and radiologically, making the distinction between the two diagnostically challenging. We present the case of a 45-year-old female presenting with a lump breast, which was later found out to be metastasis from medullary carcinoma thyroid.

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

    Conclusion: The possibility of finding of an incidental metastatic tumor in the thyroid gland from a previous unknown and non-diganosed primary (as CCRC in our case was is rare and account only for less than 1% of malignancies. Nonetheless, the thyroid gland is a frequent site of metastasis and the presence of “de novo” thyroid nodules in oncologic patients must be always considered and studied.

    Resistance to thyroid hormone (RTH) is a rare autosomal hereditary disorder characterized by increased serum thyroid hormone (TH) levels with unsuppressed or increased thyrotropin concentration. It remains unknown whether the coexistence of RTH with papillary thyroid carcinoma (PTC) and Hashimoto thyroiditis (HT) is incidental or whether it possesses a genetic or pathophysiological association. In the present study, a case of RTH with PTC and HT in an 11-year-old Chinese patient was examined and the clinical presentation of RTH with PTC was discussed. In addition, the possible associations between RTH, PTC and HT were determined. HT was confirmed in the patient using an autoimmune assay and thyroid ultrasound. RTH was diagnosed on the basis of clinical manifestations, laboratory information and gene analysis, and PTC was diagnosed according to histological results. Results of BRAF V600E mutation analysis were positive. A literature review of 14 cases of RTH with PTC was included for comparison. The present case report indicates an association of RTH with PTC and HT coexistence in the patient. Close follow-up, histological evaluation and BRAF V600E mutation detection should be performed in each RTH case with HT, since a persistent increase in TSH may be a risk factor for the development of thyroid neoplasm.

    Thyroglobulin measurement with fine-needle aspiration (Tg-FNA) is a sensitive method for detecting metastatic papillary thyroid carcinoma (PTC). However, the diagnostic threshold is not well established and the influence of the thyroid gland on the cutoff value is also controversial. In this study, patients were classified into two groups according to the presence or absence of thyroid tissue, to determine an appropriate cutoff value for clinical practice. Patients with a history of thyroid nodules or surgery for PTC and with enlarged cervical lymph nodes on an FNA examination were enrolled for Tg-FNA detection. One hundred ninety-six lymph nodes (189 patients) were included: 100 from preoperative patients, 49 from patients treated with partial thyroid ablation, and 47 from patients with total thyroid ablation. In 149 lymph nodes from patient with thyroids, the cutoff value for Tg-FNA was 55.99 ng/mL (sensitivity, 95.1%; specificity, 100%), whereas in 47 lymph nodes from patients without a thyroid, it was 9.71 ng/mL (sensitivity, 96.7%; specificity, 100%). Thus, the cutoff value for Tg-FNA was higher in patients with thyroids than in patients without thyroids. The cutoff value for Tg-FNA is influenced by residual thyroid tissue, and a higher cutoff value is recommended for patients with thyroids than for patients without thyroids.

    Breast carcinoma's gene therapy is a hotspot in study of the tumor's therapy in the recent years. Currently the major therapy methods that in the experimentative and primary clinical application phases include immunological gene therapy, multidrug resistance gene therapy, antisense oligonucleotide therapy and suicide gene therapy. The gene targeting brachytherapy, which is combined with gene therapy and radiotherapy has enhanced the killer effects of the suicide gene and nuclide in tumor cells. That has break a new path in tumor's gene therapy. The further study in this field will step up it's space to the clinical application

    Benign hypofunctional cold thyroid nodules (CTNs) are a frequent scintiscan finding and need to be distinguished from thyroid carcinomas. The origin of CTNs with follicular morphologic features is unresolved. The DNA damage response might act as a physiologic barrier, inhibiting the progression of preneoplastic lesions to neoplasia. We investigated the following in hypofunctional follicular adenoma (FA) and follicular thyroid cancer (FTC): i) the mutation rate of frequently activated oncogenes, ii) the activation of DNA damage response checkpoints, and iii) the differential proteomic pattern between FA and FTC. Both FTC and FA, which did not harbor RAS, phosphoinositide-3-kinase, or PAX/peroxisome proliferator activated receptor-γ mutations, express various proteins in common and others that are more distinctly expressed in FTC rather than in FA or normal thyroid tissue. This finding is in line with the finding of constitutive DNA damage checkpoint activation (p-Chk2, γ-H2AX) and evidence for replicative stress causing genomic instability (increased cyclin E, retinoblastoma, or E2F1 mRNA expression) in FTC but not FA. We discuss the findings of the increased expression of translationally controlled tumor protein, phosphatase 2A inhibitor, and DJ-1 in FTC compared with FA identified by proteomics and their potential implication in follicular thyroid carcinogenesis. Our present findings argue for the definition of FA as a truly benign entity and against progressive development of FA to FTC. Copyright © 2011 American Society for Investigative Pathology.

    Amiodarone is a frequently used antiarrhythmic drug with a high antiarrhythmic potency. However, beside its antiarrhythmic effects Amiodarone also reveals a variety of adverse effects and drug-related complications. The affected organs include the eyes, skin, lungs, nervous system, liver, gastrointestinal tract and the thyroid. The thyroid is one of the most frequently affected organs by Amiodarone. An altered hormone equilibrium always occurs and has to be distinguished from Amiodarone induced hyperthyroidism and hypothyroidism. The differentiation of these states frequently causes problems and may even be a diagnostic and therapeutic challenge in certain cases. The article gives an overview on the interactions between Amiodarone and the thyroid, the diagnostic and therapeutic options and management strategies of patient on Amiodarone therapy in the view of thyroid function.

    Between 1969 and 1985, 30 patients with carcinomas of the eyelid were treated by radiation, including 19 primary cases and 11 secondary cases. The latter were less controlable than the former. According to histology, there were 21 squamous cell carcinomas, 6 basal cell carcinomas and 3 adenocarcinomas. Among the 21 patients with squamous cell carcinomas, 5 had local recurrences, 10 had lymph node metastasis and 3 had distant metastasis. Patients with other histological classifications had no local recurrences, except for one who received incomplete therapy due to diabetes. Almost all of the controlled patients with squamous cell carcinomas were treated with a TDF value greater than 90. Although the visual function was damaged by irradiation in seven patients, the lesions of 6 of them were too advanced to avoid radiation injuries. (author)

Much still remains unknown about the molecular mechanisms of thyroid cancer. Studies have found that some certain relationship between ARAP3 and human cancer. However, the role of ARAP3 in thyroid cancer has not been well explained. This study aimed to investigate the role of ARAP3 gene in papillary thyroid carcinoma. Methods: Whole exon sequence and whole genome sequence of primary papillary thyroid carcinoma (PTC samples and matched adjacent normal thyroid tissue samples were performed and then bioinformatics analysis was carried out. PTC cell lines (TPC1, BCPAP, and KTC-1 with transfection of small interfering RNA were used to investigate the functions of ARAP3 gene, including cell proliferation assay, colony formation assay, migration assay, and invasion assay. Results: Using next-generation sequence and bioinformatics analysis, we found ARAP3 genes may play an important role in thyroid cancer. Downregulation of ARAP3 significantly suppressed PTC cell lines (TPC1, BCPAP, and KTC-1, cell proliferation, colony formation, migration, and invasion. Conclusion: This study indicated that ARAP3 genes have important biological implications and may act as a potentially drugable target in PTC.

    In breast cancer a decrease in triiodothyronine concentration was revealed with the normal level of thyroxine that may be associated with the disturbed peripharal metabolism into triiodothyronine. The lowering of thyroid functional activity is noted during radiation therapy of patients at menopause. Administration of thyroidin during radiation therapy to elderly patients with the 3 stage of the disease compensated for hormone deficiency producing a sparing effect on the thyroid, and influenced the therapeutic results favorably. A high level of the somatotropic hormone was observed in patients, of the reproductive age and at menopause, the level of insulin was increased in all the patients.

    Decision to perform concurrent ipsilateral thyroidectomy on patients with hypopharyngeal cancer is important, and unnecessary thyroidectomy should be avoided if oncologically feasible. We hypothesized that concurrent ipsilateral thyroidectomy is not routinely required to prevent occult metastasis. This study aimed to determine the prevalence of histological thyroid invasion in patients with hypopharyngeal cancer, and to refine the indications for prophylactic ipsilateral thyroidectomy in patients with hypopharyngeal cancer. A retrospective review of the medical records from the Department of Otolaryngology at Yonsei University College of Medicine was conducted from January 1994 to December 2009. A total of 49 patients underwent laryngopharyngectomy with thyroidectomy as a primary treatment of hypopharyngeal cancer. The incidence of thyroid gland involvement was 10.2%. The most common route of invasion was direct extension through the thyroid cartilage. Thyroid cartilage invasion (p=0.034) was the most significant factor associated with thyroid invasion. Disease-specific survival at 5 years was lower in patients with than without thyroid gland invasion (26.7% vs. 55.2%, respectively; p=0.032). Disease-free survival at 5 years was also lower in patients with than without thyroid gland invasion (20.0% vs. 52.1%, respectively; p=0.024). Ipsilateral thyroidectomy in combination with total laryngopharyngectomy is indicated when invasion of the thyroid cartilage is suspected in patients with hypopharyngeal cancer.

    To investigate the mRNA expressions of RASSF1A, Galectin-3 and TPO in papillary thyroid carcinoma and some other thyroid benign lesions, and evaluate their diagnostic significance. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of RASSF1A, galectin-3 and TPO in the samples from 73 cases, including 23 cases with papillary thyroid cancer, 16 with nodular goiter, 29 with thyroid adenoma and 5 with Hashimoto's disease. A statistically significant difference in the mRNA expression of RASSF1A, Galectin-3 and TPO was observed between papillary thyroid carcinoma and follicular benign lesions (P0.05). A negative correlation of the expression of RASSF1A and Galectin-3 mRNA was found between thyroid benign lesions and malignant ones (P = 0.000). While the mRNA expression of RASSF1A and TPO was positively correlated between benign and malignant lesions (P = 0.028). Loss of expression of RASSF1A and TPO mRNA but high expression of Galectin-3 mRNA in papillary thyroid carcinoma are common. Therefore, the products of these three genes may be closely related to the development of thyroid papillary carcinoma, and may be used as useful markers in differential diagnosis of papillary thyroid carcinoma from the benign lesions. The results are more reliable if this detection method is used in combination with other techniques.

    Adenocystic carcinoma most commonly develops in the major salivary glands, on the other hand it is rare for adenocystic carcinoma to develop in the larynx. We report a case of adenocystic carcinoma in the larynx. A 54-year-old male was hospitalized with symptoms of hoarseness and dyspnea on exertion. He presented a tumor that developed at the base of the right arytenoid, and covered over the glottis. It was confirmed to be adenocystic carcinoma (solid type) by biopsy. Positron emission tomography (PET)-CT also revealed a left cervical lymph node metastasis and multiple pulmonary metastases (T1N2cM1). He was treated with proton therapy to the larynx to prevent airway obstruction by growth of the tumor and to preserve the larynx because he had uncontrollable pulmonary metastasis. Although the tumor vanished after the treatment, one month later he had halitosis, dyspnea and bilateral vocal cord palsy. Despite administration of an antibacterial drug and steroid, there was no improvement to the narrowness of the glottis. A tracheotomy was therefore performed three months after the proton therapy. PET-CT, which was performed after the tracheotomy, suggested growth of the residual tumor or laryngeal radionecrosis. This study confirmed that proton therapy is effective for adenocystic carcinoma in the larynx. However, proton therapy also was found to cause laryngeal radionecrosis. These results indicate the importance of evaluating the side effects of radiation therapy and providing that information to the patient. (author)

    Full Text Available ABSTRACT INTRODUCTION: An ongoing discussion is found in medical literature about the reasons for changes in thyroid carcinoma incidence patterns over the last decades. OBJECTIVE: To analyze the clinical and pathological characteristics of thyroid carcinoma cases over a decade. METHODS: Cross-sectional study over an historical cohort. Medical records of 628 thyroid cancer cases in a single center were reviewed. 597 patients were included. Microcarcinoma cases were selected for a qualitative analysis phase, in which medical records were reviewed for better understanding of thyroid nodule and thyroid cancer diagnosis process. RESULTS: An increase in the proportion of cases with thyroid cancer diagnosis was observed throughout the decade; new cases were predominantly tumors of less than 2 cm, with histopathological signs of low aggressiveness. There was an increase in proportion of cases with malignant cytological results among microcarcinomas. CONCLUSION: There is a trend for increase in thyroidectomies due to cancer in this institution, with proportional increment of cases with histopathological characteristics indicative of early disease. Among microcarcinomas, there is an increasing group represented by cancer cases that were not incidentally diagnosed, related to an enhancement in preoperative diagnostic methods.

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

    Medullary thyroid carcinoma is a rare tumor accounting for less than 10% of thyroid neoplasm. This tumor is characterized by important histological polymorphism which makes morphological diagnosis difficult and immunohistochemical study often necessary. We aim to perform a retrospective review of clinical and pathological characteristics of medullary carcinoma. We will discuss the place of immunohistochemistry in the positive diagnosis and as a prognostic factor. patients with thyroid medullary carcinoma diagnosed in department of pathology at carcinologic institute between 1998 and 2013 were retrospectively included. Clinic, radiologic and prognostic variables were assessed. Slides were reviewed for all the patients with confirmed tumors. Twenty-seven patients with CMT were identified. The average age was 55 years with predominance of males. The average consultation time was 16 months. The most common presentation symptom was a cervical lymph node. Total thyroidectomy was performed in 23 patients. Tumor was nodular and unique in 22 cases. The average size was 2.1 cm. CMT was of mixed type containing both medullary and papillary compound in four cases. Amyloid substance was present and abundant in 21cases. Positive staining for calcitonin was observed in 16 cases. Distant metastasis or metastatic lymph nodes was observed in eight cases with an average period of 42 months. Radiotherapy was performed in fifteen cases and two patients received chemotherapy. In the absence of amyloid deposits, immunohistochemical staining with calcitonin is useful to confirm the diagnosis. The prognosis of this entity is more pejorative than papillary thyroid carcinoma.

    Full Text Available Abstract Introduction Anaplastic thyroid carcinoma, which is one of the most aggressive, malignant tumors in humans, results in an extremely poor prognosis despite chemotherapy and radiotherapy. The present study was designed to evaluate therapeutic effects of radiation by glycerol on p53-mutant anaplastic thyroid carcinoma cells (8305c cells. To examine the effectiveness of glycerol in radiation induced lethality for anaplastic thyroid carcinoma 8305c cells, we performed colony formation assay and apoptosis analysis. Results Apoptosis was analyzed with Hoechst 33342 staining and DNA ladder formation assay. 8305c cells became radiosensitive when glycerol was added to culture medium before X-ray irradiation. Apoptosis was induced by X-rays in the presence of glycerol. However, there was little apoptosis induced by X-ray irradiation or glycerol alone. The binding activity of whole cell extracts to bax promoter region was induced by X-rays in the presence of glycerol but not by X-rays alone. Conclusion These findings suggest that glycerol is effective against radiotherapy of p53-mutant thyroid carcinomas.

    Full text: In this paper the author presents his experience with radioiodine therapy of thyroid functional autonomies. The objectives of this study were to establish the efficacy and determine the adverse effects of radioiodine therapy of patients with thyroid functional autonomies. The main pathologic attribute of thyroid functional autonomies is the loss of regulation in the axis of hypothalamus-hypophysis-thyroid. The main cause of functional autonomy of the thyroid is iodine deficiency. Over a period of 30 years (1974-2004) 799 patients (age from 33 to 86 years; average age 58.7 years; the female: male ration was 7.4:1) with unifocal functional autonomy (UFA), multifocal functional autonomy (MFA) and disseminated functional autonomy (DFA) received at least one treatment of radioiodine. For diagnostics and the evaluation of radioiodine therapeutic effect of functional autonomies a thyroid scintigraphy is the basic and necessary procedure. In some patients a common scintigraphy with special imaging modulation, in some patients a scintigraphy after suppression or stimulation by means of thyroid hormones or TSH were done. We have also performed a thyroid ultrasonography, an assessment of a serum level of a total and free thyroxine, total triiodothyronine, TSH, radioiodine accumulation test, estimation of radioiodine effective half-life, in some patients TRH-TSH test. The follow-up examinations were done in all patients after 4-6 months, another examination after one year in 545 patients and after two years in 254 patients. One therapeutic dose received 733 patients (91.74%) and it was sufficient for an elimination of functional autonomies. Some patients were retreated if there was the evidence of small or no treatment effect and no elimination of functional autonomies. Two radioiodine treatments received 62 patients (7.76%) and three treatments 4 patients (0.5%). We advocate individual pre-therapeutic dosimetry to determine the activity necessary to achieve a

    Full Text Available Anaplastic thyroid carcinoma (ATC is one of the most aggressive human cancers. Actually, ATC is refractory to conventional therapies, including surgery, chemotherapy, radiotherapy, and radioiodine (131I therapy. Accordingly, genetic and molecular characterizations of ATC have been frequently and periodically reviewed in order to identify potential biological markers exploitable for target therapy. This review briefly focuses on main molecular events that characterize ATC and provides an update about preclinical studies. In addition, the overexpression of transferrin receptor 1 (TfR1/CD71 by neoplastic cells of ATC is emphasized in that it could represent a potential therapeutic target. In this regard, new therapeutic approaches based on the use of monoclonal or recombinant antibodies, or transferrin-gallium-TfR1/CD71 molecular complexes, or lastly small interfering RNAs (siRNAs are proposed.

    This study aimed to assess the diagnostic efficacy of Korean Thyroid Imaging Reporting and Data System (K-TIRADS) features for distinguishing follicular thyroid adenoma (FTA) from follicular thyroid carcinoma (FTC). From January 2013 to July 2016, 46 follicular neoplasms in 45 patients who underwent preoperative thyroid ultrasonography (US) and thyroid surgery were included. The US features of each thyroid nodule were retrospectively evaluated by a single radiologist using a picture archiving and communication system. The diagnostic indices of K-TIRADS for follicular neoplasms were calculated according to whether K-TIRADS category 4 lesions were excluded or classified as benign or malignant. Of the 46 follicular neoplasms (mean size, 3.1±1.6 cm), 37 were FTAs (mean size, 3.1±1.7 cm) and nine were FTCs (mean size, 3.0±1.5 cm). A statistically significant difference was found between FTAs and FTCs regarding the margin (P=0.035), while no significant differences were observed in the composition, echogenicity, shape, orientation, calcification, or vascularity of the lesions (P<0.05). The FTAs belonged to K-TIRADS categories 3 (n=22) and 4 (n=15), while the FTCs belonged to K-TIRADS categories 3 (n=4), 4 (n=4), and 5 (n=1). However, there was no statistically significant difference in the distribution of K-TIRADS categories between FTAs and FTCs (P=0.184).K-TIRADS features were not helpful for distinguishing FTA from FTC, although follicular neoplasms showed a high prevalence of K-TIRADS categories 3 and 4.

    Full Text Available Aim.The purpose of this study was to examine the outcome of patients with skeletal metastases from well-differentiated thyroid carcinoma and analyse the effect of variables that influence the prognosis of this disease. Method. We retrospectively reviewed 352 patients treated and followed-up at the Charlotte Maxeke Johannesburg Academic Hospital’s thyroid cancer clinic from 1982 - 1999. Findings. Skeletal metastases were diagnosed in 24 (6.8%, 17 at presentation to the thyroid clinic, and 7 at follow-up. Patients’ ages ranged from 30 - 77 years (mean 53.9 years and the female:male ratio was 3.8:1. Based on the original pathology reports from resected tumours, 9 were papillary and 15 were follicular cancers. Twenty-three of the 24 patients underwent thyroid surgery as the initial management – total thyroidectomy in 18, subtotal thyroidectomy in 3, and lobectomy plus neck dissection in one. The diagnosis of thyroid cancer was based on lobectomy in a single subject. Radioactive iodine (RAI was used as part of the original treatment; external radiation therapy (XRT was mainly used to alleviate severe symptoms. Twenty-one patients (87.5% were treated with RAI; 11 (45.8% received radiotherapy. Seven patients died – 4 from neurological disease directly associated with bone metastases. Of the 17 surviving patients, 2 appeared to be disease-free, 8 were asymptomatic despite overt bony disease, and 7 had persistent symptoms which much improved in 5. Bone metastases were uncommon, and follicular cancer predominated in this survey. Conclusion. RAI therapy improves quality of life in most patients. There is a place for XRT.

    The aim of this study was to compare ultrasonographic features in patients with lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC) having suspicious thyroid nodule(s) in a background of heterogeneous parenchyma and to determine the clinical and radiological predictors of malignancy. We reviewed the cases of 100 patients who underwent ultrasonography between April 2011 and October 2012, and showed suspicious thyroid nodule(s) in a background of heterogeneous parenchyma. Eight patients who did not undergo ultrasonography-guided fineneedle aspiration cytology (FNAC) and 34 cases of follow-up ultrasonography after initial FNAC were excluded. We compared the benign and malignant nodules in terms of their clinical and radiological factors. For the 58 nodules including 31 LTs (53.4%) and 27 PTCs (46.6%), the mean tumor sizes of the two groups were 0.96 cm for LT and 0.97 cm for PTC. A univariate analysis revealed that PTCs were more frequent in patients younger than 45 years and having microcalcifications than was LT. An independent predictor of PTC after adjustment was an age of <45 years. LT mimics malignancy in a background of heterogeneous parenchyma on ultrasonography. A young age of <45 years is the most important predictor of malignancy in this condition.

    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.

    Radioiodine therapy is used in the treatment of patients with differentiated thyroid cancer both to ablate residual thyroid tissue after initial surgery and to treat residual, recurrent, or metastatic cancer. In most institutions, therapy remains based on empirically determined, fixed amounts of radioiodine that do not account for individual differences in the mass of tissue to be treated and in radioiodine kinetics. Over the last 25 years, we have developed and refined techniques based on pre-therapy, diagnostic quantitative radiation dosimetry and imaging with 131I that permit individualized treatment which balances the success of the treatment and the risk of serious acute adverse effects on the bone marrow and lungs. In this manuscript we discuss patient selection and preparation for radioiodine therapy and outline in detail methods for performing quantitative dosimetry studies. Guidelines for the application of these results to the treatment of individual patients are presented.

    The thyroid gland is removed en bloc during laryngectomy. There are no objective criteria for deciding the extent of thyroid gland resection in primary hypopharyngeal cancer cases. The present study aimed to determine the incidence of thyroid gland involvement in hypopharyngeal cancer and identify the various predictors of this involvement. This paper reports a retrospective analysis of 358 patients with hypopharyngeal cancer, who underwent total laryngectomy with partial or total pharyngectomy at Tata Memorial Hospital, Mumbai between 2004 and 2010. The mean age of this population was 61 years. The pyriform sinus was the most common hypopharyngeal subsite involved (in 89 per cent of cases). Most patients underwent hemi-thyroidectomy as part of their surgery. The thyroid gland was involved in only 13 per cent of cases. Thyroid gland involvement is not common in hypopharyngeal cancer. Cases that involved the post-cricoid area, subglottic extension, extralaryngeal spread or prior tracheostomy were associated with a higher risk of thyroid gland involvement. Ipsilateral thyroidectomy is sufficient in most patients undergoing surgery (laryngectomy with partial or total pharyngectomy) for hypopharyngeal cancers.

    Full Text Available Introduction: Fine Needle Aspiration Biopsy (FNAB allows the cytological differentiation of benign and malignant thyroid nodules. However, the method itself is not adequate in determining some cases. For example, the diagnosis of Follicular Variant Papillary Thyroid Carcinoma (FV-PTC can be challenging. In the current study we investigate the protein profiles of FV-PTC and classical variant PTC (CV-PTC with no lymph node metastasis and compare it with benign thyroid tissue. Method: We used CV-PTC (n = 6, FV-PTC (n = 6 and benign thyroid tissues (n = 6 to prepare tissue lysates. Proteins from each group were trypsin and lys-C digested. The samples were analyzed on a Q Exactive Orbitrap mass spectrometer. Results: We identified 2560 proteins across all 18 specimens. Protein profiles revealed that there was no clear distinction between benign and FV-PTC samples. However, further examination of our data showed that proteins in energy metabolism have altered in FV-PTC. Proteomic pathway analysis showed marked alteration of the actin cytoskeleton proteins, especially several members of Arp2/3 complex were significantly increased in CV-PTC. We made the novel observation that IQGAP1 protein was significantly increased in CV-PTC, whereas IQGAP2 protein was highly expressed in FV-PTC lesions, suggesting differential roles of IQGAP proteins in thyroid pathology. Conclusion: In the present study, mass spectrometry based label free quantification approach was applied to investigate the protein profiles of FV-PTC, CV-PTC and benign thyroid tissues. This study pointed out that actin cytoskeleton proteins, IQGAP proteins and changes in energy metabolism play predominant roles in thyroid pathology.

    Background Blood and lymph vessel invasion are well-recognized markers of tumor aggressiveness, as these are the routes that lead to metastases. Thyroid tumors, depending on the histological variant, tend to have distinctive biological behaviors and use different vascular routes to metastasize, yet the mechanisms underlying the metastatic process are still poorly understood. Objectives The aim of this study was to assess how the lymph vessel density (LVD) in different histological types of thyroid tumors, and in their surrounding tissue, correlate with the presence of lymph node metastases (LNM) and tumor pathological features. Methods Lymph vessels of papillary thyroid carcinomas (PTC), of the classical (CVPTC, n = 50) and follicular variants (FVPTC, n = 18), and medullary thyroid carcinomas (MTC, n = 34) were immunohistochemically stained against antigen D2-40. The stained area was quantified using a computerized morphometric analysis tool and correlated with the tumor pathological characteristics. Results LVD within all analyzed thyroid tumor subtypes was significantly lower than in the surrounding thyroid tissues (p < 0.001). Despite intratumoral LVD being significantly higher in CVPTC than in FVPTC, and peritumoral LVD being significantly higher in MTC than in PTC (p < 0.05), no correlations were found between LVD (either intratumoral or peritumoral) and the presence of lymph node metastasis. Conclusions As no LVD differences were found amongst thyroid tumors with or without LNM, dissemination is more likely to depend on the tumor ability to invade the abundant lymph vessel network of the surrounding thyroid tissue than on the ability of the tumor to promote de novo lymphangiogenesis.

    Papillary carcinoma is the most common malignant tumour of thyroid gland which can occur in any age group with most tumours diagnosed in the third and fifth decades predominantly in the females. FNAC is emerging as the first line of investigation for any thyroid enlargement including tumours as a safe, rapid and cost -effective procedure. Many studies have reported diagnostic accuracy of FNAC in detecting neoplasms. The present study aims to evaluate the diagnostic accuracy of FNAC in the cytodiagnosis of papillary carcinoma and to highlight the clinco-pathologic correlation. A total of 37 cases were diagnose cytologically as papillary carcinoma, out ofwhich 28 cases were histologically proved. The remaining 9 cases were not available for biopsy. It was observed that careful cytomorphologic assessment with particular attention to cellular arrangement and nuclear characteristics aided in the correct diagnosis.

    Background Previous analysis of CBX7 expression in a large number of thyroid adenoma and carcinoma samples revealed a progressive reduction of CBX7 levels that was well related with the malignant grade of thyroid neoplasias. Hürthle cell tumors are unusual thyroid neoplasms characterized by the presence of particular cells called oncocytes. Objectives In order to develop new tools for a more accurate diagnosis of Hürthle cell tumors of the thyroid, we evaluated CBX7 protein levels to verify the possible presence of an expression signature. Methods CBX7 expression was evaluated by immunohistochemistry in a panel of thyroid tissue sections including normal thyroids, goiters, follicular adenomas and oncocytic lesions. Results CBX7 expression was low or null in 68% of Hürthle adenomas, whereas it was comparable to normal thyroid tissue in Hürthle hyperplasias and follicular adenomas. Conclusions Reduced expression of CBX7 suggests a more aggressive identity of Hürthle adenomas with respect to non-Hürthle ones. PMID:25759796

    The presence of thyroglobulin in serum of patients with differentiated thyroid carcinoma was studied by a specific radioimmunoassay. Seventy-three patients with thyroid carcinomata were examined, 16 of whom had pulmonary or skeletal metastase, 11 local metastases, and the others no metastases. Patients with generalized metastases had very high serum thyroglobulin concentrations while those with local metastases had slightly elevated or normal concentrations. Those with remaining thyroid tissue had mainly normal thyroglobulin levels and patients with neither metastases nor remaining thyroid tissue had undetectable serum thyroglobulin. In seven patients with metastases it was possible to observe the development of serum thyroglobulin after 131 I treatment. In all cases the serum thyroglobulin concentration paralleled the development of the clinical status. Elevated serum thyroglobulin was also found in benign thyroid diseases such as hyperthyroidism and endemic goitre. Measurement of thyroglobulin in serum is therefore of little value in differentiating between benign and malignant thyroid diseases, but it is a good method for the follow-up control of patients with differentiated thyroid carcinomata. Because normal thyroglobulin levels do not exclude local metastases, additional examinations are necessary if normal thyroglobulin levels are found. When thyroglobulin is undetectable, metastases can be excluded and the measurement of thyroglobulin in serum can replace all other methods in the follow-up control. (author)

    Background Papillary thyroid carcinoma (PTC) is the most common thyroid cancer. The widespread use of neck ultrasound (US) and US-guided fine-needle aspiration cytology is triggering an overdiagnosis of PTC. Objective To evaluate clinical behavior and outcomes of patients with PTCs ≤2 cm, seeking for possible prognostic factors. Methods Clinical records of cases with histological diagnosis of PTC ≤2 cm followed at the Endocrine Department of Instituto Português de Oncologia, Lisbon between 2002 and 2006 were analyzed retrospectively. Results We identified 255 PTCs, 111 were microcarcinomas. Most patients underwent near-total thyroidectomy, with lymph node dissections in 55 cases (21.6%). Radioiodine therapy was administered in 184 patients. At the last evaluation, 38 (14.9%) had evidence of disease. Two deaths were attributed to PTC. Median (±SD) follow-up was 74 (±23) months. Multivariate analysis identified vascular invasion, lymph node and systemic metastases significantly associated with recurrence/persistence of disease. In addition, lymph node involvement was significantly associated with extrathyroidal extension and angioinvasion. Median (±SD) disease-free survival (DFS) was estimated as 106 (±3) months and the 5-year DFS rate was 87.5%. Univariate Cox analysis identified some relevant parameters for DFS, but multivariate regression only identified lymph node and systemic metastases as significant independent factors. The median DFS estimated for lymph node and systemic metastases was 75 and 0 months, respectively. Conclusions In the setting of small PTCs, vascular invasion, extrathyroidal extension and lymph node and/or systemic metastases may confer worse prognosis, perhaps justifying more aggressive therapeutic and follow-up approaches in such cases.

  19. Diagnosis and therapy for parotid carcinoma

    The incidence of parotid carcinoma is lower than that of squamous cell carcinoma of the head and neck. Parotid carcinomas are rare, representing about 2% of all head and neck malignancies. In addition, there are many histological types differing in the grade of malignancy. We have employed specific strategies to diagnose/treat parotid carcinoma over the past 20 years. Many reports support that prognostic factors for parotid carcinomas are TNM, local invasion, histologic differentiation (grade), perineural invasion, and facial palsy. In these factors, it is generally accepted that stage and histological grade are the most important factor. Therefore, planning of therapy should be carried out according to each stage and histopathologocal type because each has different tumor activity. Fine needle aspiration biopsy of the salivary gland is an accepted, sensitive and specific technique in the diagnosis of the tumors. However, its accuracy is generally poor, especially in low/intermediate grade carcinoma. Since it is difficult to diagnose histopathological type in each case, we attempt to classify parotid carcinoma into three groups, low, intermediate, and high grade carcinoma. In case of the same group, we can perform almost the same operation planning. In the neck dissection for N0 patients, elective neck dissection (END) may not be necessary in low-grade patients. However, currently, END should be performed in all parotid carcinoma patients because of the low accuracy of grade diagnosis. It was previously thought that cancer of the salivary gland was radioresistant. However, more recent reports suggest otherwise. Postoperative radiotherapy is superior to that for surgery alone. Indications of radiotherapy are the following: high grade cancer, perineural spread of tumor, node metastasis, positive surgical margin, and aggressive cancer. (author)

    A 76-year-old woman with a 10-year history of chronic glomerulonephritis was treated at a clinic after presenting with a gradual worsening of the renal function. The patient had no history of tuberculosis. She was subsequently hospitalized for uremic symptoms and treated with internal shunt insertion and dialysis. Thyroid ultrasonography was performed to screen for secondary hyperparathyroidism, which revealed a calcified thyroid mass and cervical lymph node swelling. Fine-needle aspiration biopsy was thus conducted to assess suspected thyroid cancer. The cytological findings showed few follicular epithelial cells, without any signs of malignancy. However, a diagnosis of thyroid cancer continued to be strongly suspected based on the imaging features. Total thyroidectomy and bilateral cervical regional lymph node dissection were therefore performed, and the pathological examination of the thyroidectomy specimen disclosed scattered epithelioid granulomas with caseous necrosis in the entire right lobe as well as the cervical lymph nodes. Based on these findings, the patient was diagnosed with thyroid tuberculosis. As the symptoms and imaging findings of tuberculosis are nonspecific in elderly patients, it is necessary to consider this disease in this population. We therefore propose the inclusion of thyroid tuberculosis in the differential diagnosis of elderly patients who present with malignant thyroid tumors on aspiration biopsy cytology, regardless of whether or not they have a previous history of tuberculosis.

    We reported two cases of basal cell carcinoma (BCC) that developed after radiation therapy. A 50-year-old woman, who had received an unknown amount of radiation therapy for the treatment of intracranial germinoma at the age of 22, presented with several tumors around the radiation ulcer. All tumors showed BCC. A 33-year-old woman, who had received an unknown amount of radiation therapy on the head for the treatment of leukemia at the age of 2, presented with a black nodule within the area of irradiation. The tumor showed BCC. We discuss the occurrence of BCC after radiation therapy. (author)

    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.

    Anaplastic carcinoma of thyroid gland is one of the four most malignant tumors in humans. It appears in one or two patients per million per year. It is very rare in children. A 17-year-old female patient was admitted to the Clinical Department of ENT and Head and Neck Surgery, Split University Hospital Center, for thyroid gland surgery due to rapid growth of a node in the thyroid gland left lobe. Preoperative examination indicated benign nature of changes. Total thyroidectomy with levels VI and VII neck dissection was done. Intraoperative slide of the left lobe was malignant. Positron emission tomography and computed tomography were also done. The finding was negative. The patient was examined by an ENT-oncology team and juvenile radiotherapy was administered. It was found to be carcinoma stage IVa according to TNM classification. One year after the operation, the patient was well and had no signs of illness. This case report is a contribution to the existing but scarce knowledge of anaplastic carcinoma of thyroid gland in young patients in the world.

    Seventy-four American white thyroid cancer patients were typed for HLA-A, B, and DR antigens. A significant increase in HLA-DR7 was found in the nonradiation-associated thyroid cancer patients (42.5%, 20/47 cases), compared to 22.8% of 979 normal controls. The association is stronger in the follicular and mixed papillary-follicular subgroup (52.0%, 13/25 cases, P corrected less than 0.01). The occurrence of various malignancies in family members was found in 57.9% of HLA-DR7 positive patients, versus 20% of HLA-DR7 negative patients, in a retrospective record review. Although the frequency of HLA-DR7 was not increased in the radiation-associated thyroid cancer patients (22.2%, 6/27 cases), the interval from the irradiation date to the onset date of thyroid cancer was shorter in HLA-DR7 positive cases (17.3 +/- 6.2 years) than in HLA-DR7 negative patients (29.4 +/- 11.5 years). This data suggest that HLA-DR7 is associated with and may influence development of thyroid cancer

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

    The tall cell variant (TCV) of papillary thyroid carcinoma (PTC) is an aggressive variant of PTC that is believed to have worse outcomes than classical PTC. The objective of this study was to investigate the incidence, survival, and disease recurrence of patients with TCV and compare them with other PTC in a whole population. Information on all thyroid carcinomas diagnosed in Iceland from 1990 to 2009 was obtained from the Icelandic Cancer Registry. PTC diagnosed postmortem was excluded. The date of diagnosis, sex, and age at diagnosis were registered. All histopathology material was re-evaluated, and papillary thyroid tumors classified as either TCV or other types of PTC. Tumors were classified as TCV if >50% of cells were tall (height > twice the width). TNM stage was determined for all the cases. Endpoints were thyroid cancer-specific death and thyroid cancer recurrence. Out of 376 patients diagnosed with PTC in the study period, 49 (13%) were classified as TCV. Patients with TCV were older (66 years vs. 49 years, pIceland with an incidence of 0.5/100,000 for men and 0.7/100,000 for women. Patients diagnosed with TCV have worse five-year disease-specific survival than patients with other PTC. TCV histology is an independent risk factor for disease recurrence but not for disease-specific survival.

    Full Text Available RNAs may act as competing endogenous RNAs (ceRNAs, a critical mechanism in determining gene expression regulations in many cancers. However, the roles of ceRNAs in thyroid carcinoma remains elusive. In this study, we have developed a novel pipeline called Molecular Network-based Identification of ceRNA (MNIceRNA to identify ceRNAs in thyroid carcinoma. MNIceRNA first constructs micro RNA (miRNA–messenger RNA (mRNAlong non-coding RNA (lncRNA networks from miRcode database and weighted correlation network analysis (WGCNA, based on which to identify key drivers of differentially expressed RNAs between normal and tumor samples. It then infers ceRNAs of the identified key drivers using the long non-coding competing endogenous database (lnCeDB. We applied the pipeline into The Cancer Genome Atlas (TCGA thyroid carcinoma data. As a result, 598 lncRNAs, 1025 mRNAs, and 90 microRNA (miRNAs were inferred to be differentially expressed between normal and thyroid cancer samples. We then obtained eight key driver miRNAs, among which hsa-mir-221 and hsa-mir-222 were key driver RNAs identified by both miRNA–mRNA–lncRNA and WGCNA network. In addition, hsa-mir-375 was inferred to be significant for patients’ survival with 34 associated ceRNAs, among which RUNX2, DUSP6 and SEMA3D are known oncogenes regulating cellular proliferation and differentiation in thyroid cancer. These ceRNAs are critical in revealing the secrets behind thyroid cancer progression and may serve as future therapeutic biomarkers.

    Purpose: To evaluate exposure and dosimetry to family members and environment due to outpatient radioiodine therapy of differentiated thyroid carcinoma. Methods: Twenty patients were treated with 100-150 mCi of iodine-131 on an out-patient basis. Family members dosimetry (n = 27) and potential doses inside the house were measured with thermoluminescent dosimeters. Surface contamination and radioactive wastes were also monitored. Results: Less than 1.0 mSv doses were found in 26 co-habitants and 2.8 mSv in a single case (inferior to the acceptable value of 5.0 mSv/procedure). Potential doses in the houses were inferior to 0.25 mSv, excluding the patients bedroom (mean value = 0.69 mSv). Surface contamination (mean = 4.2 Bq.cm{sup -2}) were below clearance levels. Radioactive wastes generated had a volume of 2.5 liters and a total activity estimated in 90 {mu}Ci, with a calculated exposure close to the background radiation levels. Conclusions: No radiological impact was detected after iodine therapy with 100-150 mCi on an out-patient basis followed by experienced professionals. (author)

    Currently, anaplastic thyroid carcinoma has a very poor prognosis and there is an unmet need for new therapeutic options. Therefore, this study aims to identify upregulated genes in anaplastic thyroid carcinoma with known drug interactions that could serve as new therapeutic targets. Publicly available microarray expression profiles of anaplastic thyroid carcinoma and normal thyroid tissue were collected. FGmRNA-profiling was applied, which is a recently developed method that enhances the ability to capture the downstream effects of genomic alterations on gene expression levels. Next, a comparison between FGmRNA-profiles of anaplastic thyroid carcinoma and normal thyroid samples was performed. Significantly upregulated genes in ATC were prioritized based on: 1) known interaction with antineoplastic drugs, 2) current drug development status in human, and 3) association with biologic pathways known to be involved in anaplastic thyroid carcinoma carcinogenesis. In the study, 25 anaplastic thyroid carcinoma and 80 normal thyroid samples were included for FGmRNA-profiling. Class comparison identified 301 significantly upregulated genes. Following prioritization, MTOR, MET, WEE1, PSMD1, MERTK, FGFR3, RARG, and ESR2 were identified as potential therapeutic targets. We prioritized 8 potential therapeutic druggable targets in anaplastic thyroid carcinoma. Ultimately, inhibition of these therapeutic targets might improve patient outcome in anaplastic thyroid carcinoma by reducing locoregional disease and distant metastases.

    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.

    PurposeTo assess the effectiveness of percutaneous laser ablation (PLA) of cervical lymph node metastases from papillary thyroid carcinoma.Materials and Methods24 patients (62.3 ± 13.2 year; range 32–80) previously treated with thyroidectomy, neck dissection, and radioiodine ablation underwent ultrasound-guided PLA of 46 {sup 18}FDG-PET/CT—positive metachronous nodal metastases. All patients were at high surgical risk or refused surgery and were unsuitable for additional radioiodine ablation. A 300 µm quartz fiber and a continuous-wave Nd-YAG laser operating at 1.064 mm were used. Technical success, rate of complications, rate of serological conversion, and local control at follow-up were derived. Fisher’s exact test and Mann–Whitney U test were used and Kaplan–Meier curve calculated.ResultsTechnical success was obtained in all 46 lymph nodes (100 %). There were no major complications. Thyroglobulin levels decreased from 8.40 ± 9.25 ng/ml before treatment to 2.73 ± 4.0 ng/ml after treatment (p = 0.011), with serological conversion in 11/24 (45.8 %) patients. Overall, local control was obtained in 40/46 (86.9 %) lymph nodes over 30 ± 11 month follow-up, with no residual disease seen at imaging in 19/24 (79.1 %) patients. Local control was achieved in 40/46 (86.9 %) lymph nodes at 1 year and in all of the 25 nodes (100 %) followed for 3 years. Estimated mean time to progression was 38.6 ± 2.7 m.ConclusionUltrasound-guided PLA is a feasible, safe, and effective therapy for the treatment of cervical lymph node metastases from papillary thyroid carcinoma.

    1985-01-01

    We investigated the uptake of therapeutic doses of 131-Iodine in a capsular form which were given to 16 patients with benign thyroid disease, and compared it to the uptake of a dose of a liquid diagnostic sodium iodide I-131 ( 131 I) given to the same patients. The aim of this study was to determine the additional radiation dose sustained by the gastric mucosa, and thus, to establish the safety of this galenic form of 131 I. It was found that the average capsule-dissolution time was about 12 min, with a large standard deviation of about 7 min. Using these data and a theoretical radiation-dose calculation, we estimated that the maximum dose to the gastric mucosa was approximately 250 rad (250 cGy) for a therapeutic activity of 5 mCi (185 MBq), which is the maximum dose which may be given as single application to out-patients in Switzerland. Thus, 131 I administered in a capsular form is a safe galenic form for therapeutic use in patients with thyroid disease. (orig.)

    Papillary thyroid carcinoma (PTC) is the most common thyroid cancer. EBV is one of the most important viruses related to different types of malignancies. This study investigated the relationship between EBV and papillary thyroid carcinoma. In this study the presence of Epstein-Barr Nuclear Antigen 1 (EBNA1) gene in papillary thyroid carcinoma tissues were examined by nested-PCR method. Paraffin-embedded tissues (N=41) blocks of thyroid cancer were used. DNA was extracted from all samples and then samples were evaluated for the presence of EBV gene. In 41 samples, EBNA1 was detected in 65.8% of patients with papillary thyroid carcinoma which was significantly higher in younger ages. The significant presence of EBV genome in papillary thyroid carcinoma suggests that this virus may play a role in this cancer especially in younger ages. As a result, monitoring of patients with EBV latent infection for PTC can be very important. Copyright © 2017 Elsevier GmbH. All rights reserved.

    2010-11-01

    Full Text Available Abstract Introduction Calcitonin (Ct and carcinoembrional antigen (CEA are widely used as tumor markers for the post-operative follow-up of patients with medullary thyroid carcinoma (MTC. In patients with elevated serum Ct and CEA their dynamics can be described by calculating the doubling time (DT - the time, they need to double the serum concentration. Previous reports concluded that the Ct and CEA DT have prognostic value in MTC patients. Patients and methods We retrospectively analyzed data of 70 MTC patients with elevated serum Ct or CEA. In total, doubling times were calculated and the DT of the less favorable marker was used to stratify the patients into the low- and high-risk group with the cut-off value of 2 years. The survival analysis was performed using Cox proportional hazard method. Results The doubling time Conclusions The calcitonin and carcinembrional antigen doubling times of less than two years are negative prognostic factors for MTC recurrence-free and total survival in patients with persistent or recurrent disease. They may be used as predictive factors for more intensive search of disease localization in asymptomatic hypercalcitoninemia and for therapy choice in symptomatic disease.

    Full Text Available Malignant transformation of a mature cystic teratoma (MCT is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a, mucinous adenocarcinoma (b, and strumal carcinoid tumor (c—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

    Radioactive iodine ( 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 131 I) after 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 ( 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 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

    Suppressive therapy with levothyroxine is the main step in treatment of differentiated thyroid cancer (DTC). However, subclinical hyperthyroidism is associated with deleterious effects on cardiovascular and skeletal systems. Metformin may have a suppressive effect on TSH level. We performed a single blind randomized controlled trial on the effect of short term Metformin therapy on 50 non-diabetic patients with DTC (mean age of 39.68 ±8.7 years) under suppressive therapy with levothyroxine. Metformin (500 mg) or placebo was added to the drug regimen of the patients and levothyroxine dose decreased by 33%. TSH and thyroid hormone values were measured at the beginning of the study and 3 months after treatment. Forty-six patients had papillary and 4 had follicular carcinoma. The mean dose of levothyroxine was 2.2±0.48 µg/kg. The mean TSH level at the beginning of the study was 0.05±.04 mIU/L. The mean age, weight and baseline TSH level was not significantly different between metformin and placebo groups (P>0.2). In the metformin group, the mean (±SD) TSH level was significantly increased from 0.03±0.04 to 3.1±5.7 mIU/L after 3 months of intervention (P=0.01) and the mean thyroid hormone levels were significantly decreased (Plevothyroxine dose reduction in patients with DTC.

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.

    Full Text Available Breast metastases are a relatively rare condition and account for approximately 0.5–2% of all breast tumors. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary tumor. Breast metastases from medullary thyroid cancer (MTC are very rare with only 21 reported cases in the literature. Some MTCs mimic primary invasive lobular carcinoma of the breast histopathologically and radiologically, making the distinction between the two diagnostically challenging. We present the case of a 45-year-old female presenting with a lump breast, which was later found out to be metastasis from medullary carcinoma thyroid.

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

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

    1988-01-01

    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 131 I 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 131 I 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) [pt

    Full Text Available A 52-year-old male was referred to our department with complaints of a painless midline neck swelling. Clinico-radiological evaluation suggested a 6 × 5 cm thyroglossal cyst with non-palpable nodules in isthmus and right lobe of thyroid gland. FNAC of the thyroglossal cyst was suggestive of papillary carcinoma. He underwent Sistrunk′s operation, total thyroidectomy, and central compartment neck dissection. Co-existence of papillary carcinoma of thyroid gland and thyroglossal cyst is a rare presentation and in this report, we describe our management and propose an evidence-based algorithm to assist decision-making in the management of these patients in future.

    1993-01-01

    In a prospective study, ten patients with recurrent medullary thyroid carcinoma (markedly elevated calcitonin levels) were investigated by means of somatostatin receptor scintigraphy (SRS) with 111 In-pentetreotide. Scintigraphically, 30 sites of pathological uptake were found, mostly located in the neck and upper mediastinum. So far, 18 suspected tumour sites underwent histological examination and 14 of them could be verified as metastases of medullary thyroid carcinoma (MTC). The remaining four putative tumour lesions turned out to be false positive scintigraphic findings caused by chronic inflammation and somatostatin receptor positive tumours other than MTC. We conclude that SRS is a promising imaging modality for localization of MTC recurrence and may thus make a contribution to better management of this patient group. (Author)

This need is amplified when dealing with therapeutic amount of radionuclides. Among all the procedures dealing with the use of radiopharmaceuticals, it is easiest to think of 131 I, since this is the most widely used unsealed source of a radiopharmaceutical for treatment of thyroid cancer and hyperthyroidism and carries with it most of the problems associated with therapy applications

    Objective: Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human cancers and often shows resistance to multimodal therapeutic approaches. It has been shown that the transcriptional repressor Slug inhibits the chemotherapeutic agent-induced apoptosis of cancer cells. We evaluated whether targeting of Slug could augment doxorubicin (DOX)-induced apoptosis of ATC cells. We also determined changes in PUMA (p53-upregulated modulator of apoptosis) expression levels to identify poss...

  13. Dosimetric considerations relative to radionuclides for thyroid diagnosis and therapy

    International Nuclear Information System (INIS)

    Atkins, H.L.

    1976-01-01

    Recent changes have occurred in the radionuclidic approach to the diagnosis and therapy of thyroid diseases. These changes have been directed toward reduction of radiation dose by the use of short-lived radionuclides for imaging and toward better control of late effects of therapy by substituting iodine-125 for iodine-131. Imaging of the thyroid is now widely performed following the administration of technetium-99m or iodine-123. Some problems exist relative to the use of technetium-99m in that the distribution of radioactivity in the thyroid is not always identical to the distribution of radioiodine. Iodine-123 represents a substantial advance over iodine-131 despite contamination of the former with small amounts of other radioiodines. The high incidence of induced hypothyroidism following iodine-131 therapy of thyrotoxicosis has spurred interest in the use of iodine-125. The biological effectiveness of iodine-125 is believed to be greater because of the high abundance of Auger electrons and possibly because of chemical effects following molecular disruption. Clinical results to date are discussed

  14. Targeted Therapy for Medullary Thyroid Cancer: A Review

    2017-10-01

    Full Text Available Medullary thyroid cancers (MTCs constitute between 2 and 5% of all thyroid cancers. The 10-year overall survival (OS rate of patients with localized disease is around 95% while that of patients with regional stage disease is about 75%. Only 20% of patients with distant metastases at diagnosis survive 10 years which is significantly lower than for differentiated thyroid cancers. Cases with regional metastases at presentation have high recurrence rates. Adjuvant external radiation confers local control but not improved OS. The management of residual, recurrent, or metastatic disease till a few years ago was re-surgery with local measures such as radiation. Chemotherapy was used with marginal benefit. The development of targeted therapy has brought in a major advantage in management of such patients. Two drugs—vandetanib and cabozantinib—have been approved for use in progressive or metastatic MTC. In addition, several drugs acting on other steps of the molecular pathway are being investigated with promising results. Targeted radionuclide therapy also provides an effective treatment option with good quality of life. This review covers the rationale of targeted therapy for MTC, present treatment options, drugs and methods under investigation, as well as an outline of the adverse effects and their management.

    Full Text Available Background: Cystic papillary thyroid carcinoma (CPTC is a variant of papillary carcinoma that has many mimickers in cytological grounds. Aim: To study the cytomorphologic features of CPTC and compare them to those of other cystic thyroid lesions using fine-needle aspiration cytology (FNAC. We also aimed to identify the cytomorphologic features that distinguish CPTC from other cystic thyroid lesions. Materials and Methods: Seventy-three cases of CPTC were included in the study. The cytomorphologic features of these cases were analyzed. The FNA smears of other thyroid lesions with cystic changes (300 colloid goiters, 290 adenomatoid nodules, 11 follicular neoplasms, and 9 hurtle cell neoplasm were also studied. Results: The smears in CPTC revealed isolated follicular cells, small groups of cells with scalloped margins, cell swirls, small clusters with a cartwheel pattern, papillary clusters, intranuclear inclusions, nuclear grooves, sticky colloid, intracellular colloids, psammoma bodies, multinucleated giant cells, and foamy and hemosiderin laden macrophages. Small groups of cells with scalloped borders, cellular swirls, and small clusters with a cartwheel pattern were seen in CPTC, but not in other cystic lesions. Interestingly, mesothelial-like cells and hemophagocytic cells were seen in five and three cases of CPTC, respectively, but not in other cystic lesions. Conclusion: Mesothelial-like cells and hemophagocytic cells were observed in five and three cases of CPTC, respectively. Similar finding have not been previously reported in the literature.

    Serum Tg and I-131 WBS have been used to detect recurrent and metastatic thyroid cancers postoperatively. Tg is known to be more sensitive than I-131 WBS, and therefore, false-negative WBS cases with elevated Tg levels are frequently found. However, the clinical characteristics of false-negative Tg cases with positive WBS have not been clarified. The authors evaluated 824 postoperative patients with differentiated thyroid carcinoma who underwent post-ablation/therapy I-131 WBS. Tg negativity was defined as a Tg level of ≤2 ng/mL without TgAb under thyroid-stimulating hormone stimulation. Remission, recurrence, and metastasis were confirmed using pathologic or clinically findings. Fifty-two patients (6.3%) with functioning metastasis and negativity for TgAb were Tg-negative and posttherapy I-131 WBS-positive (TgN group), and 128 patients with functioning metastases were Tg positive and WBS positive (TgP group). The TgN group consisted of 45 cases of cervical/mediastinal lymph node metastases (86.5%) and seven cases of distant metastasis to lung or bone by follow-up WBS. The TgN group demonstrated significantly higher profiles of regional involvement than the TgP group (P < 0.029). In 47 patients in the TgN group, metastatic uptake disappeared in 33, ameliorated in four, and persisted in ten during follow-up. A significant number of differentiated thyroid cancer patients were Tg-/TgAb-negative despite a positive WBS finding. Cervical and mediastinal lymph nodes were predominant sites of metastasis in the TgN group. WBS should be undertaken routinely as a complementary modality to detect functioning recurrence and metastasis regardless of serum Tg results. (orig.)

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

    Full Text Available The possibility of a coincidental appearance of hyperparathyroidism and thyroid cancer is not often considered because of its low incidence. Here, we present a case of a 49-year-old woman with a parathyroid adenoma coexisting with two sites of papillary thyroid carcinoma. Dual-phase 99mTc-methoxyisobutylisonitrile (MIBI parathyroid imaging before the operation correctly visualized the site of the parathyroid adenoma. In addition, two papillary thyroid carcinomas showed faint uptake of 99mTc-MIBI on delayed image. Total thyroidectomy and parathyroidectomy of a solitary parathyroid adenoma were performed. The patient subsequently underwent radioiodine-131 ablation and was treated with T4 suppression. This case illustrates the need for clinical awareness of concomitant hyperparathyroidism and thyroid cancer. Dual-phase 99mTc-MIBI parathyroid imaging may be useful for detecting indolent thyroid cancer before it becomes a distinct disease.

    We report a case of multinodular thyroid goiter in an 80-year-old man who successfully underwent tracheal stent placement for respiratory distress caused by the thyroid goiter and following two radiofrequency (RF) ablation sessions performed for thyroid volume reduction. This sequential treatment allowed elective stent removals four weeks after the second RF ablation session because the thyroid volume had been progressively reduced. Combination therapy of temporary airway stenting and RF ablation for the treatment of thyroid goiter has two advantages, i.e., immediate reliefs of dyspnea with airway stenting and reductions of the thyroid volume with RF ablation, and thus, allowing symptom reliefs even after the stent removals.

    INTRODUÇÃO: O carcinoma papilífero é o tipo mais comum de câncer da tireoide e a tireoidite de Hashimoto é a causa mais frequente de hipotireoidismo em áreas onde os níveis de iodo são adequados. Vários investigadores detectaram incidência aumentada de carcinoma papilífero da tireoide em pacientes com tireoidite de Hashimoto. Na rotina de diagnósticos histopatológicos há uma aparente associação entre as duas patologias. OBJETIVO: Determinar a relação entre tireoidite de Hashimoto e carcinoma ...

    Full Text Available Papillary carcinoma is a prominent malignancy originating from follicular cells. This disease generally shows an indolent character, but patients demonstrating certain clinicopathological features have a dire prognosis. At present, Western countries adopted almost routine total thyroidectomy with radioactive iodine (RAI ablation, while limited thyroidectomy with extensive prophylactic lymph node dissection has traditionally been performed for most patients in Japan. Recently, accurate evaluation of carcinoma stage can be performed on preoperative imaging studies, especially on ultrasonography. It
