    Full text: Introduction: The majority of thyroid cancers have a slow evolution, a more often loco-regional extension, and a good forecast. Remote metastases, when they exist, generally touch the osseous skeleton and/or pulmonary tissue. However, unusual metastatic localizations much more exceptional are possible. The authors report through these work five cases of atypical metastasis of differentiated thyroid carcinoma followed in Nuclear Medicine department of Ibn Sina hospital in Rabat under the directives of Professor N Ben Rais. Materials and methods: Our five patients had initially undergone a total thyroidectomy for differentiated thyroid carcinoma histologically confirmed. They had profited 4 weeks after the surgical gesture from a reference isotopic exploration (131 Iodine whole body scan and thyroglobulin dosage). The paraclinic assessment was supplemented by a computed tomography (CT). Results: Revealing symptomatology in the first 69 year old patient was dominated by blindness associated with an elective up-take of radioactive 131-Iodine on the level of hypophyseal gland extending to the sphenoid bone. The second 55 year old patient reported right basithoracic pains resisting to the usual antalgic treatment with a bulky mass driving back the kidney right to the bottom at CT with and important up-take 131-Iodine at whole body scan; a surrenalectomy was thus carried out with conservation of the kidney. The three other patients presented at the clinical examination dermohypodermic nodular lesions of various localizations whose anatomopathologic study had confirmed their thyroid metastatic origin. In the 5 patients the rate of thyroglobulin was considerably high. An activity of 3,7 GBq 131-Iodine was managed with the 5 patients. The evolution was marked, in the short run, at the first patient by a recovery partial of the sight, the disappearance of pain in the second patient and a remarkable reduction of thyroglobulin level for all our patients.

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

    Eighty-two patients with advanced well-differentiated thyroid carcinoma were treated. Sixty-six patients survived for more than 10 years and 10-year-survival rate was 80.5 %. Multidisciplinary treatment, consisting of surgery, radioiodine, external irradiation and TSH suppression was studied. We emphasized that radioiodine treatment after thyroid-ectomy was unique and an ideal therapeutic model for locally advanced, distant metastatic and recurrent cases as far as radioiodine was accumulated on thyroid cancer tissue. External irradiation was sometimes effective for the remnant thyroid carcinoma and metastases. Occassionally, well-differentiated thyroid carcinoma showed good response to TSH suppression therapy using thyroid hormone. The significance of conversion of well-differentiated carcinoma of thyroid to anaplastic carcinoma was noticed. We recognized that radiation therapy was effective for advanced well-differentiated thyroid carcinoma in multidisciplinary treatment. (author)

    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.

    Poorly differentiated thyroid carcinoma (PDTC) has been recognized for the past 30 years as an entity showing intermediate differentiation and clinical behavior between well-differentiated thyroid carcinomas (ie, papillary thyroid carcinoma and follicular thyroid carcinoma) and anaplastic thyroid carcinoma; however, there has been considerable controversy around the definition of PDTC. In this review, the evolution in the definition of PDTC, current diagnostic criteria, differential diagnoses, potentially helpful immunohistochemical studies, and molecular alterations are discussed with the aim of highlighting where the diagnosis of PDTC currently stands.

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

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

    Hyperthyroidism due to thyroid carcinoma is rare, and most cases are caused by hyperfunctioning metastatic thyroid carcinoma rather than primary carcinoma. Among primary hyperfunctioning thyroid carcinoma, multifocal thyroid carcinoma is exceedingly rare, with the only one case being reported in the literature. Here, we describe the case of a 62-year-old woman with multifocal functioning thyroid carcinoma. Technetium-99m (99m Tc) scintigraphic imaging showed four hot areas in the thyroid gland. Histopathological examination of all four nodules revealed papillary carcinoma, corresponding to hot areas in the 99m Tc scintigram. DNA sequencing of the thyrotropin receptor (TSH-R) gene from all nodules revealed no mutation, indicating that activation of TSH-R was unlikely in the pathophysiogenesis of hyperfunctioning thyroid carcinoma in the present case.

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

    Thyroid cancer is rare in children, with only 3-6% of thyroid malignancies occurring in children, and constitutes but 6% of head and neck tumors. Over 95% thyroid cancer are differentiated, and 10% of these occur in children of adolescents. Any of the histologic types that occur in adults may be in children, but they are most often differentiated thyroid carcinomas. The etiologies of thyroid carcinoma are unknown, but factors considered in pathogenesis include irradiation, sex and age. The incandesce of thyroid carcinoma in a solitary coddle in a child has been described as high as 70%. History and /or physical examination alone are unlikely to advance the diagnosis, and with exception of plasma CT in medullary thyroid carcinoma, blood studies are unhelpful in the diagnosis of thyroid carcinoma. Radiographs and ultrasound imaging are helpful in planning treatment and follow-up, but are unlikely to be needed for initial diagnosis. One of the main indication of thyroid scan in the pediatric group is thyroid nodule. FNAB is established as the most effective method of diagnosis in adults, although in children it may be less reliable. While radionuclide scintigraphy may be considered for initial screening, FNAB is well established and its specificity allows it to negate the need for a substantial number of operation. Treatment of differentiated thyroid carcinoma in children is more controversial. Some authors maintain that modified or subtotal thyroidectomy is appropriation this disease, others maintain that total thyroidectomy is required Nevertheless, radioiodine therapy is considered to be standard in the treatment of iodine-avid thyroid carcinomas for ablation of the thyroid remnant following surgery and for treatment of iodine-avid distant diseases. The front-line treatment of medullary thyroid carcinoma is aggressive surgery. Total thyroidectomy is indicated, In general treatment with chemotherapy, extemal radiation and I-131 are not helpful, however radioactive

    Thyroid gland carcinomas usually appear as afunctional and hypofunctional lesions on thyroid scintigrams, but some rare cases of thyroid carcinoma with scintigraphic hyperfunctional lesions have also been reported. The aim of our retrospective study was to elucidate the frequency of carcinomas in patients operated for solitary hyperfunctional thyroid nodules and to represent their demographic and clinical features. During one decade (1997/2006), 308 patients were operated for solitary hyperfunctional thyroid nodules in the Centre for Endocrine Surgery in Belgrade. Malignancy was revealed in 9 cases (about 3 %) by histopathological examination. In 6 cases papillary microcarcinomas were found adjacent to dominant hyperfunctional adenomas, while in 3 cases (about 1 %) real hyperfunctional carcinomas were confirmed. Follicular carcinoma was diagnosed in 2 cases and papillary carcinoma in one. All 3 patients were preoperatively hyperthyroid. In both patients with follicular carcinoma we performed lobectomies. In the third case we carried out a total thyroidectomy considering the intraoperative frozen section finding of a papillary carcinoma. According to our results the frequency of solitary hyperfunctioning thyroid carcinomas is about 1 %, so that the possibility that a hyperfunctional nodule is malignant should be considered in the treatment of such lesions. © Georg Thieme Verlag KG Stuttgart ˙ New York.

    Diffuse thyroid enlargement in a child is a rare presenting symptom of thyroid carcinoma. A papillary carcinoma may be hidden in a diffuse lymphocytic thyroiditis and should be carefully searched for during surgery. Furthermore, the finding, in frozen sections, of psammoma bodies in a lymphocytic thyroiditis should raise the suspicion of an occult malignant neoplasm. A case illustrating these diagnostic difficulties in a 5-year-old child is presented.

    Papillary thyroid carcinomas in humans are associated with the ret/PTC oncogene and, following loss of p53 function, may progress to anaplastic carcinomas. Mice with thyroid-targeted expression of ret/PTC1 developed papillary thyroid carcinomas that were minimally invasive and did not metastasize. These mice were crossed with p53-/- mice to investigate whether loss of p53 would promote anaplasia and metastasis of ret/PTC1-induced thyroid tumors. The majority of p53-/- mice died or were euthanized by 17 weeks of age due to the development of thymic lymphomas, soft tissue sarcomas, and testicular teratomas. All ret/PTC1 mice developed thyroid carcinomas, but tumors in p53-/- mice were more anaplastic, larger in diameter, more invasive, and had a higher mitotic index than tumors in p53+/+ and p53+/- mice. Thyroid tumors did not metastasize in any of the experimental p53+/+ and p53+/- mice anaplasia and invasiveness of thyroid carcinomas.

    Since February, 1977, 735 patients having a history of receiving radiation therapy for benign conditions of the head and neck areas during infancy and childhood were examined in a thyroid screening program, and 159 patients were found to have palpable thyroid nodules. These patients had thyroid function tests and indirect laryngoscopy and were followed closely on suppression therapy consisting of either Cytomel or thyroid extract. Thyroidectomy was advised in those in whom the nodules persisted or increased in size. This study documents the incidence of carcinoma and other benign pathological changes and postoperative complications in this group of patients. So far, 49 patients had either a lobectomy with isthmusectomy or a total thyroidectomy. Eleven patients were found to have carcinoma (six had papillary, fou had mixed papillary and follicular, and one had follicular carcinoma). Three patients had a therapeutic modified neck dissection following the documentaion of microscopic involvement of paratracheal lymph nodes. A high incidence of chronic nonspecific thyroiditis, postradiation fibrosis, and follicular adenomas were also found in these patients. Three patients had temporary hypocalcemia (two weeks) and none had wound infection, hematoma, or postoperative nerve palsy. Of patients who had surgical resection, 22.4% showed thyroid carcinoma

    To present a case of papillary carcinoma in an autonomously hyperfunctioning thyroid nodule. We chronicle the clinical and laboratory findings in a patient with a painless neck mass, with a particular focus on the pathologic findings after surgical removal of the right thyroid lobe. A 39-year-old woman had an enlarging nodule of the right thyroid lobe. Results of thyroid function tests suggested subclinical hyperthyroidism. Two months later, the patient complained of increasing swelling in the neck (but still had no symptoms suggestive of hyperthyroidism). Thus, resection of the right thyroid lobe was performed. Pathologic analysis disclosed low-grade papillary thyroid carcinoma within the nodule, with a small rim of compressed inactive-appearing thyroid tissue surrounding the nodule. Subsequently, she underwent total thyroidectomy and follow-up care for thyroid carcinoma. Although solitary hyperfunctioning nodules of the thyroid gland are usually considered benign, the current case suggests that the diagnosis of autonomous thyroid nodules does not preclude thyroid carcinoma in a functioning nodule.

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

    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.

    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.

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

    The incidence of thyroid carcinoma in hyperthyroidism varies considerably from as low as 0.3% to as high as 16.6% with a higher rate in toxic nodular goiters. Occult thyroid carcinoma (thyroid carcinoma was 5.6% (23 cases). In detail, a neoplasm occurred in 5 cases of Graves' disease (specific incidence: 3.8%), in 13 cases of toxic nodular goiter (12.5%) and in 5 cases of hyperfunctioning adenomas (2.8%). 19 cancers were papillary (12 in toxic nodular goiter, 3 in Graves' disease, 4 in hyperfunctioning adenomas), three were follicular (1 in Graves' disease, 1 in toxic nodular goiter, 1 in hyperfunctioning adenomas) and 1 medullary in Graves' disease. A papillary carcinoma was diagnosed preoperatively on fine needle aspiration with ultrasonography in only two patients with Graves' disease and confirmed by postoperative histological examination on permanent section. We do not believe in the frozen-section examination intraoperatively because it's not diagnostical for follicular lesions and evaluates rarely capsular invasion. Twenty patients received total thyroidectomy and four of them also lymphoadenectomy. Three patients received emithyroidectomy: in two cases for occult papillary carcinoma and in the last case for local cancer invasion (T4N0M0). Twenty patients are alive and with no evidence of cancer recurrence. Mean follow-up is 59.6 months. Our retrospective study shows a progressive increase of the incidence of coexisting thyroid malignancy and hyperthyroidism especially in toxic nodular goiter, probably related to extended surgical indications. Our findings do confirm that, even in the presence of hyperthyroidism, all thyroid nodules require careful diagnostics for exclusion of malignancy.

    To determine the frequency and profile of carcinoma in multi-nodular goiter and solitary thyroid nodule. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from January 1999 to January 2009. Methodology: Cases with solitary thyroid nodules and multi-nodular goiter were included. Patients under 12 years of age, cystic benign lesion in solitary thyroid nodules or those multi-nodular goiters which were not causing pressure symptoms, cosmetic problems or sign of malignancy were excluded. In solitary thyroid nodule, hemithyroidectomy was done and if histopathology examination revealed carcinoma thyroid then completion thyroidectomy was done. In multi-nodular goiter sub-total thyroidectomy done. Results were described as frequency percentages and mean. Results: Out of 397 patients of multi-nodular goiter only one patient was found to be papillary carcinoma (0.25%). In 220 patients of solitary thyroid nodules, 93 patients were diagnosed as carcinoma of thyroid (42.27%). Others diagnosed in solitary thyroid nodule were thyroid adenoma, colloid goiter, thyroiditis and multi-nodular goiter. The frequency of papillary carcinoma in 65.95% occurring females of 12-30 years of age and being multifocal in 6.45%, follicular carcinoma in 23.40%, medullary carcinoma in 7.44%, anaplastic carcinoma in 2.12% and lymphoma in 1.01%. Female were predominantly involved and papillary carcinoma was common in 12-30 years of age (71.63%) and follicular was common in 30-40 years of age (68.18%). 6.45% of papillary carcinoma was found to be multifocal in nature. Conclusion: Frequency of carcinoma of thyroid is very high in solitary thyroid nodule (42.27%), but markedly low in multi nodular goiter. Papillary carcinoma is the most common variety, most of in younger female. (author)

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

    Activating mutations of GNAq protein in a hotspot at codon 209 have been recently described in uveal melanomas. Since these neoplasms share with thyroid carcinomas a high frequency of MAP kinase pathway-activating mutations, we hypothesized whether GNAq mutations could also play a role in the development of thyroid carcinomas. Additionally, activating mutations of another subtype of G protein (GNAS1) are frequently found in hyperfunctioning thyroid adenomas, making it plausible that GNAq-activating mutations could also be found in some of these nodules. To investigate thyroid papillary carcinomas and thyroid hyperfunctioning nodules for GNAq mutations in exon 5, codon 209, a total of 32 RET/PTC, BRAF, and RAS negative thyroid papillary carcinomas and 13 hyperfunctioning thyroid nodules were evaluated. No mutations were identified. Although plausible, GNAq mutations seem not to play an important role in the development of thyroid follicular neoplasms, either benign hyperfunctioning nodules or malignant papillary carcinomas. Our results are in accordance with the literature, in which no GNAq hotspot mutations were found in thyroid papillary carcinomas, as well as in an extensive panel of other tumors. The molecular basis for MAP-kinase pathway activation in RET-PTC/BRAF/RAS negative thyroid carcinomas remains to be determined.

    The incidence of thyroid carcinoma is increasing worldwide. Graves' disease is the most common hyperthyroid disease. Studies have suggested an increased risk of thyroid malignancy in Graves' disease: there has not yet been a meta-analysis to allow quantitative comparison. The purpose of this study was to determine the risk of thyroid carcinoma in Graves' disease, and to gather information on the histological subtypes of carcinoma and the co-existence of thyroid nodules. Several databases and article reference lists were searched. Inclusion criteria included appropriate diagnostic criteria for thyroid conditions and a diagnoses of carcinoma based on histology. 33 studies were selected, all reporting on surgically-resected specimens. The event rate of thyroid carcinoma in Graves' disease was 0.07 (95% CI 0.04 to 0.12). There was no data to allow comparison with patients without hyperthyroid diseases. There was no increase in the odds of developing carcinoma in Graves' disease compared to toxic multinodular goitre and toxic uninodular goitre. 88% of thyroid carcinomas in Graves' disease were papillary, with solitary papillary micro-carcinoma (diameter 10 mm or less) comprising 23% of all detected thyroid carcinomas. Patients with Graves' disease and co-existing thyroid nodules were almost 5 times more likely to be diagnosed with thyroid carcinoma than those without nodules. Thyroid malignancy in Graves' disease requiring surgical treatment should be considered as likely as in other hyperthyroid diseases needing surgical treatment. Clinicians should consider screening selected patients with Graves' disease for nodules whilst being aware of potentially over-diagnosing papillary micro-carcinoma. Crown Copyright © 2015.

    Thyroid carcinomas are rare during childhood and adolescence. They have increased recently probably due to a higher frequency radiation over the head, neck and mediastinum. The papillary carcinoma is the most common and true follicular carcinoma is far less common. Follicular thyroid carcinoma is associated with endemic goiter, genetic disorders, and increased TSH levels. Its morphological characteristics are peculiar and have been recently redefined, thus helping the diagnosis. A minimally invasive follicular thyroid carcinoma in 13 years old girl is described, presenting a hypocaptant thyroid nodule in the left lobe lower pole. The fine needle aspiration biopsy revealed a follicular cell lesion suspicious of malignancy. Thyroid lobectomy was performed reporting minimally invasive follicular carcinoma.

    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.

    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.

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

    The rare presentation of a follicular thyroid carcinoma mimicking the clinical and radionuclide features of subacute thyroiditis is described. Granulomatous thyroiditis was initially suspected on the clinical basis. Repeat fine needle aspiration cytology was suggestive of acinar proliferation with hyperfunction. Ultrasonography revealed a solid nodule with a peripheral sonolucent halo. Radionuclide angiography showed intense arterial flow of Tc-99m pertechnetate through the right lobe thyroid enlargement suggestive of malignant thyroid pathology. Surgical excision and histopathological examination revealed a follicular carcinoma involving the right lobe. 31 refs., 4 figs

    Hyperfunctioning nodules of the thyroid are thought to only rarely harbor thyroid cancer, and thus are infrequently biopsied. Here, we present the case of a patient with a hyperfunctioning thyroid nodule harboring thyroid carcinoma and, using MEDLINE literature searches, set out to determine the prevalence of and characteristics of malignant "hot" nodules as a group. Historical, biochemical and radiologic characteristics of the case subjects and their nodules were compared to those in cases of benign hyperfunctioning nodules. A literature review of surgical patients with solitary hyperfunctioning thyroid nodules managed by thyroid resection revealed an estimated 3.1% prevalence of malignancy. A separate literature search uncovered 76 cases of reported malignant hot thyroid nodules, besides the present case. Of these, 78% were female and mean age at time of diagnosis was 47 years. Mean nodule size was 4.13 ± 1.68 cm. Laboratory assessment revealed T3 elevation in 76.5%, T4 elevation in 51.9%, and subclinical hyperthyroidism in 13% of patients. Histological diagnosis was papillary thyroid carcinoma (PTC) in 57.1%, follicular thyroid carcinoma (FTC) in 36.4%, and Hurthle cell carcinoma in 7.8% of patients. Thus, hot thyroid nodules harbor a low but non-trivial rate of malignancy. Compared to individuals with benign hyperfunctioning thyroid nodules, those with malignant hyperfunctioning nodules are younger and more predominantly female. Also, FTC and Hurthle cell carcinoma are found more frequently in hot nodules than in general. We were unable to find any specific characteristics that could be used to distinguish between malignant and benign hot nodules.

    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.

    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.

    2013-02-01

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

    Both thyroid lymphoma and anaplastic carcinoma of thyroid present with rapidly growing mass in eldery patients. Anaplastic carcinoma has high mortality rate and combination of surgery, radiation therapy and multidrug chemotherapy are the best chance for cure. Prognosis of thyroid lymphoma is excellent and chemotherapy for widespred lymphoms and radiotherapy with or without adjuvant chemotherapy for tumors localized to the gland, are the treatment of choice. This article reports a 70 year old man presenting with diffuse neck swelling and hoarseness of few weeks duration. Fine needle aspiration was done and reported as anaplastic carcinoma of thyroid which thyroidectomy was planned. The slides were sent for second opinion. After review, with initial diagnosis of anaplastic carcinoma versus lymphoma, immunocytochemical study was performed. Smears were positive for B cell markers and negative for cytokeratin, so with the impression of diffuse large B cell lymphoma, the patient received two courses of chemotherapy by which the tumor disappeared during two weaks. Despite previous reports, stating easy diagnosis of high-grade thyroid lymphoma on the grounds of cytomorphological features we like to emphasize, overlapping cytologic features of the curable high grade thyroid lymphoma form noncurable anaplastic thyroid carcinoma and usefulness of immunocytochemistry to differentiate these two disease.

    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.)

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

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

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

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

    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

    To determine if proton magnetic resonance spectroscopy ( 1 H MRS) of thyroid carcinoma is feasible and to determine if 1 H MRS spectra of malignant tumors differ from that of normal thyroid tissue. We performed 1 H MRS at 1.5 T at echo-times (TE) 136 and 272 ms to examine eight patients with thyroid cancer (primary tumour or nodal metastasis) larger than 1 cm 3 in size and five volunteers with normal thyroids. Spectra acquired from six primary tumors (three anaplastic carcinomas, two papillary carcinomas and one follicular carcinoma) and two nodes (two papillary carcinoma metastases) were analyzed in the time-domain using a non-linear least squares fitting algorithm with incorporation of prior knowledge. Choline (3.2 ppm) was identified in all solid carcinomas with a mean choline/creatine of 4.3 at TE 136 ms and 5.4 at TE 272 ms. Ratios for malignant tumors at TE 136 ms ranged from 1.6 in well differentiated follicular carcinoma to 9.4 in anaplastic carcinoma. No choline was detected in normal thyroid tissues. Our results showed that 1 H MRS is a feasible technique for the evaluation of malignant thyroid tumors larger than 1 cm 3 and that proton spectra of malignant tumors differ from that of normal thyroid tissue

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

    Median ectopic thyroid may be encountered anywhere from the foramen caecum to the diaphragm. Non lingual median aberrant thyroid (incomplete descent) usually found in the infrahyoid region and malignant transformation in this ectopic thyroid tissue is very rare. We report an extremely rare case of papillary carcinoma in non lingual median aberrant thyroid in a 25-year-old female. The differentiation between a carcinoma arising in the median ectopic thyroid tissue and a metastatic papillary carcinoma from an occult primary in the main thyroid gland is also discussed.

    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.

    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.

    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.

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

    Full text: Analysis of data of the oncological outpatient clinics of the Republic of Uzbekistan confirms our data obtained in the Institute of Endocrinology showing growth in iodine deficiency disorders. In the Republic of Uzbekistan, during period from 1983 to 1999, 6374 people were detected to have thyroid carcinoma. If in 1989, 1.95 cases of thyroid tumor accounted for 100000 population, in 1999 this index reached to 2.39. Moreover, among metropolitan population this was 4.6 cases in 1989, and 8.0 in 1999. Of the 4280 patients operated for different thyroid pathologies from 1989 to 1999 in the Institute of Endocrinology, 335 (7.9%) were diagnosed to have thyroid carcinoma. Clinical presentation was: multinodular goiter in 50.8%, nodular goiter in 37.3% and autoimmune thyroiditis in 4.2% of cases. The average age of patients operated for thyroid carcinoma was 42.8 years in 1989 and 32 years in 1999. Treatment of patients with thyroid carcinoma should be near total thyroidectomy with selective lymphadenectomy independent of morphologic form of the tumor. Our data showed that only surgical method of treatment was used in 7.4% of patients but in combination of radioiodine in 81.9% of patients. Radioiodine was used to destroy remnant thyroid tissue and iodine concentrating metastases. 131I treatment for destruction of thyroid remnants after measured from the front, back and lateral positions in radical operation was given by fractionation method with average total activity being 25 mCi to 75 mCi. Metastases into neck lymph nodes and mediastinum were treated with radioactivity ranging from 50 mCi to 100 mCi. Of the total patients of differentiated thyroid cancer treated from 1995-1999, 148 were alive on 01.01.2003 with five-year survival rate of 91.4%. Our results highlight that combined surgical and radioiodine treatment of thyroid carcinoma helps in preventing recurrence, metastasis and results in increasing the lifespan of patients. (author)

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

    The biology of thyroid cancer represents a spectrum of behavior ranging from well-differentiated lesions with an excellent prognosis to anaplastic carcinoma, which is almost fatal. For this reason, it is important that clinicians have methods at their disposal to asses the characteristics of patient's thyroid malignancy. In this work we discuss the behavior of differentiated thyroid cancer in associated diseases of thyroid as: Graves' disease, chronic lymphocytic thyroiditis--Hashimoto and nodular goiter. This is retrospectively reviewing of 50 patients treated for differentiated thyroid carcinoma at Department of surgery, Clinical Centre of Montenegro in Podgorica from 1998 until 2003. We evaluated occurrence, as well as the role of this diseases in patients with thyroid cancer. We found a more favorable course of thyroid cancer in the presence of chronic lymphocytic thyroiditis and nodular goiter, a contrary Graves' disease. In associated diseases of thyroid, a significantly greater proportion of patients with thyroid cancer, have modular goiter.

    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

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

    Full Text Available 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

    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.

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

    Full Text Available 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 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.

    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

    2013-01-01

    Objective: To investigate the CT characteristics of anaplastic thyroid carcinoma and evaluate the diagnostic value of CT in this disease. Methods: The CT findings of 10 patients with pathologically proved anaplastic thyroid carcinoma were retrospectively reviewed. The patients included 7 females and 3 males. Their age ranged from 25.0 to 78 years with median of 61 years. Multi-slices plain and post contrast CT scans were performed in all patients. Results: Unilateral thyroid was involved in 6 patients. Unilateral thyroid and thyroid isthmus were both involved in 2 patients due to big size. Bilateral thyroid were involved in 2 patients. The maximum diameter of anaplastic thyroid carcinoma ranged from 2.9-12.8 cm with mean of (4.5 ± 1.4) cm. All lesions demonstrated unclear margins and envelope invasion. The densities of all lesions were heterogeneous and obvious necrosis areas were noted on precontrast images. Seven lesions showed varied calcifications, and coarse granular calcifications were found in 5 lesions among them. All lesions showed remarkable heterogenous enhancement on post-contrast CT. The CT value of solid portion of the tumor increased 40 HU after contrast media administration. The ratios of CT value which comparing of the tumor with contralateral sternocleidomastoid muscle were 0.69-0.82 (0.76 ± 0.18) and 1.25-1.41 (1.33 ± 0.28) on pre and post CT, respectively. Enlarged cervical lymph nodes were found in 6 cases (60.0%). It showed obvious homogeneous enhancement or irregular ring-like enhancement on post-contrast images and dot calcifications were seen in 1 case. Conclusions: Relative larger single thyroid masses with coarse granular calcifications, necrosis,envelope invasion, remarkable heterogeneous enhancing and enlarged lymph nodes on CT are suggestive of anaplastic thyroid carcinoma.

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

    Full text: The incidence of thyroid cancer has been in linear increase for several decades because of the evolution and the generalization of the means of diagnosis. The objective of our work is to carry out an epidemiologic approach of differentiated thyroid carcinoma in our country, with an evaluation of the recent review of literature. Materials and methods: Our work consists of a retrospective analysis of 3144 cases of differentiated thyroid carcinoma, followed in nuclear medicine department of Ibn Sina hospital in Rabat for a period of 12 years. Our evaluation parameters related to the incidence of thyroid carcinoma are age of onset, sex, size of tumor, histological type, evolution and risk factors. Results: The incidence of differentiated thyroid carcinoma was estimated in our country at 0,8 by 100000 inhabitants per year. The sex ratio was evaluated at 3,5/1 whereas the average age was 42,5 years. Papillary carcinoma represented 65,58 %, well differentiated follicular carcinoma 21,92 % and moderately differentiated carcinoma to 12,5%. The microcarcinomas were estimated at 8,1 %. The size of tumor at the time of diagnosis was higher than 2 cm in 70% of cases. The lymphatic extension was objectified in 47,6 % of papillary forms and 3,5 % of follicular carcinoma. Remote metastasis was found in 0,8 % of cases between 30 and 40 years and 4,71 % after the age of 40 years. Discussion: The cancer of thyroid is not very frequent. Indeed, its annual incidence throughout the world is 0,5 to 10 by 100.000 inhabitants with a clear female prevalence. The majority of cases occur between 15 and 50 years. This cancer is very rare in children less than 15 years. In Morocco, the incidence has increased these last decades like many countries in the world (0,8 by 100.000 inhabitants per year). We note, in addition, an increase in the prevalence of papillary microcarcinoma seeing the improvement of early tracking methods (echography, fine needle aspiration biopsy). The risk

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

    Full Text Available Papillary thyroid carcinoma (PTC is the most common epithelial thyroid tumor, accounting for more than 80% of all thyroid tumors. Recent advances in ultrasonographic screening and US-guided fine-needle aspiration biopsy (FNAB have facilitated the early detection and diagnosis of papillary thyroid carcinomas. In exceptionally rare cases, papillary thyroid tumors may assume enormous dimensions due to recurrent disease or the patient's negligence of the problem. We report an extremely rare case of a 72-year-old woman presented with a neglected giant exophytic papillary thyroid carcinoma with hemorrhagic ulcers. Computed tomography showed a mass measured 17×12 cm that caused a displacement of the trachea to the right side and reached the mediastinum. After bleeding management, patient was discharged. The patient was fully aware of her situation, but she denied any further therapeutic management.

    Carcinoma arising in lingual thyroid is an extremely rare entity accounting for only 1% of all reported ectopic thyroids. Here, we report a case of carcinoma arising in lingual thyroid, which has been successfully managed by transoral resection and bilateral neck dissections. A lingual mass 4-cm in diameter with calcification was incidentally detected by computed tomography at medical check-up. No thyroid tissue was observed in normal position. Ultrasound examination showed bilateral multiple lymphadenopathies. Fine needle aspiration biopsy from lymph node in his right neck was diagnosed as Class III and thyroglobulin level of the specimen was 459ng/ml. Due to the difficulty in performing FNA of the lingual masses, right neck dissection was performed in advance for diagnostic purpose. Pathological examination showed existence of large and small follicular thyroid tissues in several lymph nodes, suggesting lymph node metastasis from thyroid carcinoma. Two months after the initial surgery, video-assisted transoral resection of lingual thyroid with simultaneous left neck dissection was performed. Postoperative course was uneventful. Papillary carcinoma was found in the lingual thyroid and thyroid tissues were also found in left cervical lymph nodes. Video-assisted transoral resection was useful for the treatment of thyroid cancer arising in lingual thyroid. Copyright © 2018 Elsevier B.V. All rights reserved.

    2018-01-01

    Full Text Available Background. Undifferentiated anaplastic carcinoma rarely develops from chronic hyperthyroidism. Although acute hyperthyroidism can develop prior to anaplastic transformation, chronic hyperthyroidism was thought to be a protective measure against thyroid malignancy. Methods. A 79-year-old female presented acutely to the hospital with dyspnea. She had been taking methimazole for chronic hyperthyroidism due to toxic thyroid nodules, previously biopsied as benign. Upon admission, imaging showed tracheal compression, requiring a total thyroidectomy with tracheostomy for airway management. Results. Pathology demonstrated undifferentiated anaplastic thyroid carcinoma. The patient passed away shortly after hospital discharge. Despite treatment with methimazole for many years, abrupt enlargement of her toxic multinodular goiter was consistent with malignant transformation. Chronic hyperthyroidism and toxic nodules are rarely associated with thyroid malignancy, with only one previous report documenting association with anaplastic thyroid carcinoma. Conclusion. Progressive thyroid enlargement and acute worsening of previously controlled hyperthyroidism should promote concern for disease regardless of baseline thyroid function.

  7. Induction of thyroid carcinoma by ionizing radiation

    Roedler, H.D.

    1987-01-01

    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

    Whereas thyroid nodules are less common among children than among adults, the anxiety generated by the finding of a thyroid nodule is high because 20% of nodules found in children contain thyroid cancer. Discovery of a nodule in the context of hyperthyroidism is usually comforting due to the presumption that the nodule represents a benign toxic adenoma. An 11-year-old girl presented with heavy menses, fatigue, and a right thyroid mass. Laboratory evaluation revealed elevated triiodothyronine and undetectable thyroid-stimulating hormone. Thyroid ultrasonography revealed a 3.5 cm nonhomogenous nodule, and scintigraphy was consistent with an autonomous hyper-functioning nodule. Fine-needle aspiration biopsy could not rule out malignancy, and patient underwent right hemithyroidectomy and isthmusectomy. Pathology was consistent with papillary thyroid carcinoma. We report the discovery of papillary thyroid carcinoma in an autonomously hyperfunctioning nodule in an 11-year-old girl. Detection of an autonomously functioning thyroid nodule in children and adolescents does not exclude the possibility of thyroid carcinoma and warrants careful evaluation and appropriate therapy.

Its presence is often related with the more frequently branchial cyst in young adults, but also rarely related with thyroid carcinomas. 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.

    1996-01-01

    Recently hyperparathyroidism associated with some thyroid diseases, especially nonmedually thyroid carcinoma has been payed attention to. In this study we analyzed 12 cases of hyperparathyroidism (6 cases independent of thyroid diseases and 6 cases associated with thyroid diseases) and estimated the affect of association with thyroid diseases on the preoperative localization of the parathyroid glands. The results of preoperative localization of the parathyroid glands in cases independent of thyroid diseases were relatively satisfactory. On the other hand, the preoperative localization in cases associated with thyroid diseases came to false result in about half of them. It was far from satisfactory. Association of thyroid diseases strongly affected the preoperative localization of the parathyroid glands in hyperparathyroidism. Conventional imaging such as ultrasonography, CT, MRI and 201 Tl- 99m TC subtraction scintigraphy alone were not satisfactory. Now 99m Tc-MIBI scintigraphy is expected to be one of reliable imaging methods for progress in the preoperative localization. (author)

    Distant metastases occur in less than 10% of patients with differentiated thyroid carcinoma. In these patients, overall survival at 10 years is considerably reduced. Whereas cure is the initial goal of treatment, stabilisation of the disease and management of symptoms have become the primary objective in many patients with persistent radio-iodine refractory progressive disease. In the last decade, several targeted therapies have shown encouraging results in patients with advanced disease. The objective of this review is to describe the characteristics, diagnosis, overall survival, and the local and systemic available treatments for patients with distant metastases from differentiated thyroid cancer.

    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.

    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 [sup 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).

    Thyroid carcinoma is a frequent complication of childhood cancer radiotherapy. The dose response to thyroid radiation dose is now well established, but the potential modifier effect of other factors requires additional investigation. This study aimed to investigate the role of potential modifiers of the dose response. We followed a cohort of 4338 5-year survivors of solid childhood cancer treated before 1986 over an average of 27 years. The dose received by the thyroid gland and some other anatomical sites during radiotherapy was estimated after reconstruction of the actual conditions in which irradiation was delivered. Fifty-five patients developed thyroid carcinoma. The risk of thyroid carcinoma increased with a radiation dose to the thyroid of up to two tenths of Gy, then leveled off for higher doses. When taking into account the thyroid radiation dose, a surgical or radiological splenectomy (>20 Gy to the spleen) increased thyroid cancer risk (relative risk [RR] = 2.3; 95% confidence interval [CI], 1.3-4.0), high radiation doses (>5 Gy) to pituitary gland lowered this risk (RR = 0.2; 95% CI, 0.1-0.6). Patients who received nitrosourea chemotherapy had a 6.6-fold (95% CI, 2.5-15.7) higher risk than those who did not. The excess RR per Gy of radiation to the thyroid was 4.7 (95% CI, 1.7-22.6). It was 7.6 (95% CI, 1.6-33.3) if body mass index at time of interview was equal or higher than 25 kg/m(2), and 4.1 (95% CI, 0.9-17.7) if not (P for interaction = .1). Predicting thyroid cancer risk following childhood cancer radiation therapy probably requires the assessment of more than just the radiation dose to the thyroid. Chemotherapy, splenectomy, radiation dose to pituitary gland, and obesity also play a role.

    The current work was conducted to study the disease status and treatment results of patients with differentiated thyroid carcinoma referred for radioactive iodine therapy. Retrospective review of 78 patients with differentiated thyroid carcinoma referred for radioiodine therapy in the Nuclear Medicine Unit, King Abdulaziz Hospital and Oncology Center, Jeddah, Kingdom of Saudi Arabia. Analysis of the clinicopathologic characteristics, age correlation to different risk factors, treatment protocol and results were performed. Seventy seven percent were female and the female to male ratio was 3.5:1. The age of patients ranged between 13-63 years with a median age of 36 years. Cervical lymph node involvement was detected in 22 patients (25%). Papillary carcinoma was encountered in 78 patients (90%) and follicular carcinoma in 9 patients (10%). Analysis of the clinicopathologic characteristics showed no statistically significant difference between patients in the different age groups except for extrathyroid extension and lymph node involvement. Patients older than 45 years had a statistically significant lower incidence of nodal involvement and higher incidence of extra thyroid extension (P<0.02). In the current study we used a high dose method (Radioiodine-131 dose 75-100mCi) for thyroid remnant ablation after thyroidectomy (total or near total) in 67 patients. An Iodine 131 dose of 150 mCi was used in 12 patients with radioiodine-avid cervical lymph nodes and in 3 patients with gross residual tumor. In 4 patients with distant metastases an Iodine 131 dose of 200 mCi was used. For the whole study group the 5 year overall survival and disease-free survival was 96% and 88%. The current study, as with many other retrospective studies, concluded that despite the fact that differentiated thyroid carcinoma is among the most curable cancers, some patients are still at high risk for recurrent disease and associated mortality.

    To evaluate the surgical diagnosis and treatment of primary hyperthyroidism complicated with occult thyroid carcinoma. Data of 51 cases of primary hyperthyroidism complicated with occult thyroid carcinoma admitted during January 2004 to November 2014 were analyzed retrospectively. The incidence of occult thyroid carcinoma was 5.03% in hyperthyroidism,and 47 cases (92.16%) were female. The preoperative diagnosis of all these 51 cases was primary hyperthyroidism and 11 cases were diagnosed thyroid carcinoma at the same time;25 cases were diagnosed thyroid carcinoma by frozen section and the remaining 26 cases were diagnosed by postoperative pathology. Finally,26 cases underwent subtotal thyroidectomy,4 cases underwent total thyroidectomy, and 21 cases underwent total thyroidectomy with lymphadenectomy. The tumor size ranged from 0.1 to 1.0 cm [mean:(0.63 ± 0.35) cm]. The lesions were less than or equal to 0.5 cm in 28 cases (54.9%). The follow-up lasted from 1 to 121 months [mean:(28.6 ± 22.7)months] in 43 patients,and all of them survived. Primary hyperthyroidism complicated with occult thyroid carcinoma is commonly found in female patients. Preoperative diagnosis is difficult. Ultrasound is the major examining method. Frozen section can increase the detection rate. The postoperative prognosis of hyperthyroidism complicated with occult thyroid carcinoma is satisfactory.

    To examine expression of the connective tissue growth factor (CTGF) gene in human thyroid cancer and establish whether a correlation exists between the presence of CTGF protein and clinicopathological parameters of the disease. CTGF protein expression was investigated retrospectively by immunohistochemical analysis of CTGF protein levels in thyroid tumour tissue. Associations between immunohistochemical score and several clinicopathological parameters were examined. In total, 131 thyroid tissue specimens were included. High levels of CTGF protein were observed in papillary thyroid carcinoma tissue; benign thyroid tumour tissue scored negatively for CTGF protein. In papillary thyroid carcinoma, there was a significant relationship between high CTGF protein levels and Union for International Cancer Control disease stage III-IV, and presence of lymph node metastasis. In papillary thyroid carcinomas, CTGF protein levels were not significantly associated with sex or age. These findings suggest that the CTGF protein level is increased in papillary thyroid carcinoma cells compared with benign thyroid tumours. CTGF expression might play a role in the development of malignant tumours in the thyroid.

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

    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.

    The histopathology of papillary thyroid hyperplasia and papillary thyroid carcinoma is similar enough to cause a diagnostic dilemma in a few cases. Both lesions may have papillary fronds with fibrovascular cores, nuclear crowding, and nuclear anisocytosis. Formalin- fixed paraffin-embedded tissues from 30 randomly selected patients with papillary thyroid hyperplasia and an equal number from patients with papillary thyroid carcinoma were analyzed for expression of cytokeratin 19 (CK19), galectin-3, and HBME-1. Cases of papillary thyroid carcinoma had moderate to strong CK19, galectin-3, and HBME-1 reactivity although both CK19 and galectin-3 showed positive staining in a significant number of nonneoplastic thyroid cases. HBME-1 was uncommon in the nonneoplastic cases. These results indicate that HBME-1 may be useful in helping to distinguish papillary thyroid carcinoma from hyperplasia in diagnostically difficult cases.

    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.

    2016-01-01

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

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

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

  14. Control of treatment of differentiated thyroid carcinoma by measurement of thyroglobulin in serum

    1978-01-01

    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)

    Thyroid follicular carcinoma is able to produce metastatic lesions before the vanishing of the primary lesion. We present a case of a woman with a lytic, solitary, asymptomatic parietal bone lesion of 2 years of evolution. Autopsy revealed a thyroid gland with two small cystic areas and renal metastasis. Thyroid carcinoma should be included in the differential diagnosis in cases of lytic bone lesions with long evolution in patients 60 years of age or older.

    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

    A high rate of glycolytic flux, even in the presence of oxygen, is a key metabolic hallmark of cancer cells. Lactate, the end product of glycolysis, decreases the extracellular pH and contributes to the proliferation, invasiveness and metastasis of tumor cells. CD147 play a crucial role in tumorigenicity, invasion and metastasis; and CD147 also interacts strongly and specifically with monocarboxylate transporter1 (MCT1) that mediates the transport of lactate. The objective of this study was to determine whether CD147 is involved, via its association with MCT1 to transport lactate, in glycolysis, contributing to the progression of thyroid carcinoma. The expression levels of CD147 in surgical specimens of normal thyroid, nodular goiter (NG), well-differentiated thyroid carcinoma (WDTC), and undifferentiated thyroid carcinoma (UDTC) were determined using immunohistochemical techniques. The effects of CD147 silencing on cell proliferation, invasiveness, metastasis, co-localization with MCT1, glycolysis rate and extracellular pH of thyroid cancer cells (WRO and FRO cell lines) were measured after CD147 was knocked-down using siRNA targeting CD147. Immunohistochemical analysis of thyroid carcinoma (TC) tissues revealed significant increases in signal for CD147 compared with normal tissue or NG, while UDTC expressed remarkably higher levels of CD147 compared with WDTC. Furthermore, silencing of CD147 in TC cells clearly abrogated the expression of MCT1 and its co-localization with CD147 and dramatically decreased both the glycolysis rate and extracellular pH. Thus, cell proliferation, invasiveness, and metastasis were all significantly decreased by siRNA. These results demonstrate in vitro that the expression of CD147 correlates with the degree of dedifferentiation of thyroid cancer, and show that CD147 interacts with MCT1 to regulate tumor cell glycolysis, resulting in the progression of thyroid carcinoma.

    Full Text Available Background Warthin-like variant of papillary thyroid carcinoma (WLV-PTC is a relatively rare variant of papillary thyroid carcinoma with favorable prognosis. However, preoperative diagnosis using fine-needle aspiration (FNA specimens is challenging especially with lymphocytic thyroiditis characterized by Hürthle cells and lymphocytic background. To determine a helpful cytological differential point, we compared WLV-PTC FNA findings with conventional papillary thyroid carcinoma with lymphocytic thyroiditis (PTC-LT and conventional papillary thyroid carcinoma without lymphocytic thyroiditis (PTC regarding infiltrating inflammatory cells and their distribution. Preoperative diagnosis or potential for WLV-PTC will be helpful for surgeons to decide the scope of operation. Methods Of the 8,179 patients treated for papillary thyroid carcinoma between January 2007 and December 2012, 16 patients (0.2% were pathologically confirmed as WLV-PTC and four cases were available for cytologic review. For comparison, we randomly selected six PTC-LT cases and five PTC cases during the same period. The number of intratumoral and background lymphocytes, histiocytes, neutrophils, and the presence of giant cells were evaluated and compared using conventional smear and ThinPrep preparations. Results WLV-PTC showed extensive lymphocytic smear with incorporation of thyroid follicular tumor cell clusters and frequent histiocytes. WLV-PTC was associated with higher intratumoral and background lymphocytes and histiocytes compared with PTC-LT or PTC. The difference was more distinct in liquid-based cytology. Conclusions The lymphocytic smear pattern and the number of inflammatory cells of WLV-PTC are different from those of PTC-LT or PTC and will be helpful for the differential diagnosis of WLV-PTC in preoperative FNA.

    Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (nodule. 99mTC thyroid scintigraphy showed a hyperfunctioning nodule with suppression of the remainder parenchyma. Fine-needle aspiration cytology was nondiagnostic (cystic fluid). The patient was started on thiamazole 5 mg daily with subsequent normalization of thyroid function, but she developed cervical foreign body sensation and a left hemithyroidectomy was performed. Histology showed a 4 cm cystic nodule with a follicular variant papillary carcinoma and the patient underwent completion thyroidectomy, followed by radio-iodine ablation. Published literature showed an increased prevalence of autonomously functioning nodules, harbouring thyroid carcinomas in adults. Papillary carcinoma is the most frequently described but the follicular variant is rare. Although rare, thyroid cancer is not definitively excluded in hyperthyroid patients and it should always be considered as differential diagnosis. Copyright © 2018. Published by Elsevier Ltd.

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

    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.

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

    A young woman with a thyroid papillary carcinoma behaving as an autonomously hyperfunctioning nodule is described. Only 17 similar patients have been seen in the past 25 years. It is emphasized that hyperthyroidism does not exclude malignant disease in hot nodules. This possibility suggests that all thyroid nodules, either cold or hot, require careful management. Therefore, in 'at risk' cases, surgery could be the most useful treatment. (orig.)

    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.

    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

    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

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

    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.

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

    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.

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

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

    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

    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.

    A 66-year-old woman with Pendred's syndrome underwent a partial thyroidectomy when she was 17 years old. At the age of 52 years, she had a second thyroid operation because of hyperthyroidism due to a toxic multinodular goiter with a mediastinal extension consisting of several separate nodules. Five years later a hyperfunctioning metastatic follicular carcinoma was diagnosed histologically. After treatment with radioactive iodine, the patient was well. To the authors' knowledge, this is the first description of a metastatic follicular thyroid carcinoma in Pendred's syndrome and the first report of hyperthyroidism occurring after malignant degeneration of a dyshormonogenetic goiter

    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.

    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

    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.

    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.

    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 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.

    Measurement of s-Tg is of limited value in the diagnosis of primary thyroid tumor but is very useful in post-operative management of differentiated thyroid carcinoma. The sensitivity and the specificity of Tg determination is comparable to that obtained with whole body scan WBS, however, both are complimentary. In our experience, the accuracy of s-Tg determination whether on or off thyroxin medication does not differ significantly

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

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

    In a man with metastatic follicular carcinoma of the thyroid, thyrotoxicosis developed after total thyroidectomy and was successfully treated with antithyroid medications. Treatment with radioactive iodine decreased the size of the distant metastasis and eventually diminished thyroid hormone production. Follicular carcinoma complicated by hyperthyroidism requires vigorous control of the hypermetabolic state. Treatment with radioactive iodine can effectively reduce metabolic complications and tumor bulk, and yields a remission rate as high as 33%

    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.

    Radioactive iodine ( 131 I) has been found to be more sensitive and more specific than thallium-201 for the detection of distant metastases and thyroid remnants in the neck in cases of well-differentiated thyroid carcinoma. 201 Tl has been deemed particularly useful in localizing metastases or recurrence in patients with a negative 131 I scan and abnormal levels of serum thyroglobulin (Tg). This study aimed to: (1) determine the value of 201 Tl imaging in localizing metastases or recurrence in patients with well-differentiated thyroid carcinoma, and (2) evaluate the false-positive and false-negative results of 131 I and 201 Tl scintigraphy. Sixty-two thyroid remnant ablated patients who underwent simultaneous postoperative 201 Tl and 131 I scans and and serum Tg determinations were evaluated. Fifty patients had papillary thyroid carcinomas and 12 had follicular thyroid carcinomas. 201 Tl imaging was performed before the 131 I studies. Of the 62 patients who underwent 201 Tl imaging studies, 24 were found to have positive results, with local recurrence or distant metastases. Patients with positive results in the 201 Tl imaging studies tended to be older, were mor often male, had higher Tg levels and had a higher recurrence rate. Of these 24 patients, ten had negative diagnostic or therapeutic 131 I scans. Concurrently, serum Tg levels were less than 5 ng/ml in five of these ten patients. Three patients were deemed false positive by 201 Tl scans; one had a parotid tumour, one a periodontal abscess and one lung metastasis. Among the 38 patients with negative 201 Tl scans, 11 had positive findings on 131 I scans. Three had distant metastases: two with lung metastases and one with bone metastases. Patients with false-positive results on 131 I scans included those with biliary tract stones, ovarian cysts, and breast secretion. Of the 27 patients with negative 201 Tl and 131 I scans, 15 had elevated serum Tg levels. Among these, local recurrence followed by lung

    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.

    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 majority of cases reported in the literature of leukemia following treatment of thyroid disease (thyrotoxicosis and carcinoma) are of acute variety. A description is given of the development of chronic myeloid leukemia in a case of carcinoma of the thyroid treated with radioiodine and megavoltage X-ray therapy. The case history contains details of radioiodine and X-ray doses administered over the years 1961 to 1972 to a male patient, on whom a right hemithyroidectomy was carried out in 1960. The results of blood counts are also recorded for the period up to 1973. The patient died, at 57, in 1974. A total of 860 mCi of /sup 131/I was administered and the first abnormal blood count was noted two months after the last therapeutic dose. Estimates have been made of blood and thyroid doses from /sup 131/I. There has been only one other report in the literature of the development of chronic myeloid leukemia following radioiodine therapy for carcinoma of the thyroid, and although the leukemogenic hazard of /sup 131/I cannot be ruled out for this patient, it is possible that the development of leukemia was coincidental rather than due to the radioiodine therapy.

    Data in the literature communicated in 63 publications were evaluated in which scintigraphically warm or hot nodules were described as identical to a follicular or papillary carcinoma diagnosed based on histology of the resection specimen, thus suggesting autonomous hyperfunction of a malignant thyroid neoplasia. In the majority of cases, this assumption could not be accepted, or only within strict limits. In these patients, it appeared more likely that the carcinoma was located adjacent to or within a benign hyperfunctioning thyroid area or that large masses of a thyroid carcinoma had only simulated the picture of a hyperfunctioning nodule by suppression of endogenous TSH and thus of the residual parenchyma's function. In other cases, the diagnosis of a hyperfunctioning thyroid carcinoma had to be doubted or rejected owing to the lack of plausibility of the documented morphological findings. At the end of the literature survey, only 10 case descriptions unequivocally verified that, though very rarely, a papillary or follicular thyroid carcinoma may manifest itself as a solitary warm or hot thyroid nodule. Such a scintigraphical finding thus cannot be regarded as proof of benignancy of a given thyroid tumour.

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

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

    Full Text Available Papillary thyroid carcinoma (PTC metastasis to distant organs is rare and mainly includes lung and bone. Metastasis affecting oral and maxillofacial region is extremely rare. We describe a case of PTC metastasis to cheek. The patient presented with a painless swelling of the left cheek with a history of total thyroidectomy for papillary carcinoma thyroid 5 years back. Cheek metastasis from papillary carcinoma thyroid is extremely rare. To the best of our knowledge, this is the first recorded instance of cheek metastasis from PTC. Common malignancies can metastasize to unusual sites and although infrequent, may be the presenting feature. The successful management of such cases may be achieved by a multidisciplinary approach.

    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

    In patients with differentiated thyroid carcinoma high serum TSH-levels enhance 131 J-uptake in thyroid remnant and/or metastases. An effective increase of TSH could be achieved by oral administration of thyrotropin releasing hormone (TRH) even after a short T 4 /T 3 -withdrawal period so that we recommend a TRH-stimulation in all patients before a diagnostic or therapeutic 131 J-application. Adverse reactions to TRH are infrequent and usually shorttimed so that-in contrast to TSH-stimulation - TRH can be given to outpatients without any risk. (orig.) [de

    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.

    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.

    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

    Objectives To analyze the epidemiology and describe the prognostic indicators of patients with primary squamous cell carcinoma of the thyroid. Study Design and Setting Retrospective cohort study based on a national database. Methods The US National Cancer Institute's SEER registry (Surveillance, Epidemiology, and End Results) was reviewed for patients with primary squamous cell carcinoma of the thyroid from 1973 to 2012. Study variables included age, sex, race, tumor size, tumor grade, regional and distant metastases, and treatment modality. Survival measures included overall survival (OS) and disease-specific survival (DSS). Results A total of 199 cases of primary squamous cell carcinoma of the thyroid were identified. Mean age at diagnosis was 68.1 years; 58.3% were female; and 79.4% were white. Following diagnosis, 46.3% of patients underwent surgery; 55.7%, radiation therapy; and 45.8%, surgery with radiation therapy. Kaplan-Meier analysis demonstrated OS and DSS of 16% and 21% at 5 years, respectively. Median survival after diagnosis was 9.1 months. Multivariate Cox regression analysis showed that predictors of OS and DSS included age ( P Squamous cell carcinoma of the thyroid is a rare malignancy with a very poor prognosis. Surgical resection confers an overall survival benefit. Age, tumor grade, and tumor size are predictors of OS and DSS.

    Radioactive iodine ({sup 131}I) has been found to be more sensitive and more specific than thallium-201 for the detection of distant metastases and thyroid remnants in the neck in cases of well-differentiated thyroid carcinoma. {sup 201}Tl has been deemed particularly useful in localizing metastases or recurrence in patients with a negative {sup 131}I scan and abnormal levels of serum thyroglobulin (Tg). This study aimed to: (1) determine the value of {sup 201}Tl imaging in localizing metastases or recurrence in patients with well-differentiated thyroid carcinoma, and (2) evaluate the false-positive and false-negative results of {sup 131}I and {sup 201}Tl scintigraphy. Sixty-two thyroid remnant ablated patients who underwent simultaneous postoperative {sup 201}Tl and {sup 131}I scans and and serum Tg determinations were evaluated. Fifty patients had papillary thyroid carcinomas and 12 had follicular thyroid carcinomas. {sup 201}Tl imaging was performed before the {sup 131}I studies. Of the 62 patients who underwent {sup 201}Tl imaging studies, 24 were found to have positive results, with local recurrence or distant metastases. Patients with positive results in the {sup 201}Tl imaging studies tended to be older, were mor often male, had higher Tg levels and had a higher recurrence rate. Of these 24 patients, ten had negative diagnostic or therapeutic {sup 131}I scans. Concurrently, serum Tg levels were less than 5 ng/ml in five of these ten patients. Three patients were deemed false positive by {sup 201}Tl scans; one had a parotid tumour, one a periodontal abscess and one lung metastasis. Among the 38 patients with negative {sup 201}Tl scans, 11 had positive findings on {sup 131}I scans. Three had distant metastases: two with lung metastases and one with bone metastases. Patients with false-positive results on {sup 131}I scans included those with biliary tract stones, ovarian cysts, and breast secretion. Of the 27 patients with negative {sup 201}Tl and {sup 131}I

    To highlight a rare disease like multiple endocrine neoplasia (MEN)-2B variant of medullary thyroid carcinoma and to optimize the management option in such cases, we present a nine year old boy with thyroid swelling, cervical lymphadenopathy and thick lips. His calcitonin level was raised. Investigation's results of the boy were as following fine needle aspiration cytology (FNAC) was medullary carcinoma of thyroid, preoperative calcitonin was >2000pg/ml, post operative histopathological report was medullary carcinoma. Total thyroidectomy with aggressive initial neck surgery may reduce the recurrence and increase better prognosis and survival rate. Calcitonin is used as diagnostic and follow-up marker.

    Sonography, computed tomography and magnetic resonance imaging examinations did not detect recurrence or metastases of medullary thyroid carcinoma (MTC) in a patient with a rapidly rising serum calcitonin concentration after total thyroidectomy. Scintigraphy with technetium-99m labelled anti-carcinoembryonic antigen antibody, 99m Tc-colloid and iodine-131 metaiodobenzylguanidine indicated liver metastases. The three scintigrams were to some extent discrepant but from the combined information the diagnosis of hepatic metastases could be established; it was subsequently verified by sonography and aspiration biopsy. This case demonstrates the usefulness of applying nuclear medicine imaging methods for the localization of hepatic MTC metastases. (orig.)

    Thyroid malignant tumors are rarely associated with hyperfunctioning thyroid. The incidence of this co-incidence is highly variable. Here we report a rare case of papillary thyroid cancer associated with hyperthyroidism with brief literature review. A 40-year-old male, presented with palpitation, excess sweating and weight loss for one month duration. There was asymmetrical swelling of the neck, more on right side, mobile. Free T3: 11.09pmol/L, free T4: 34.41pmol/L, TFT: less than 0.005mIU/ml, Neck ultrasound showed features of background thyroiditis. Left lobe contained 9×7×5mm nodule with irregular outline and multiple dots of calcification, other nodules are of the same features. Under ultrasound guide, fine needle aspiration cytology showed features of papillary carcinoma. After preparation, total thyrodectomy done and the result of histopathological examination confirmed papillary thyroid carcinoma. The patient was put on 0.2mg thyroxine daily. Literature review has showed an increasing number of papers reporting the association of high level of thyroid function tests and thyroid malignancy. The cause of high level of TH in thyroid malignancy is thought to be due to an active mutation of the gene of TH receptor. Niepomniszcze and colleagues found that a combination of TSH receptor mutations and Ki-RAS was the main etiological factor for hyperfunction of the thyroid malignancy. Although the coexistence of them is rare, thyroid malignancy should be put in the differential diagnosis of hyperthyroid goiter. Copyright © 2016 The Authors. Published by Elsevier Ltd..

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

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

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected. Therefore, it is important carefully examine patients with Hashimoto's thyroiditis

    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 oncogene...

    2015-12-01

    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.

    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.

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

  11. Screening for sporadic or familial medullary thyroid carcinoma. Scintiscan s and radio-immunotherapy

    International Nuclear Information System (INIS)

    Rhmer, V.; Murat, A.

    2000-01-01

    The screening for sporadic medullary thyroid carcinoma relies upon calcitoninemia level, basal or during pentagastrine stimulation test. MEN2 are associated with nearly the third of medullary thyroid carcinoma. In these cases, prognosis of thyroid carcinoma is mainly driven by the tumor status at the time of surgery. Up to date, diagnosis relies upon the genetic screening. Prophylactic thyroidectomy indication may take account of calcitoninemia. Most of the molecules that have been suggested for scintiscan lack of accuracy and large use cannot be recommended. Promising results have been obtained with monoclonal antibodies anti-CEA, particularly with dual targeting antiCEA antiDTPA. This last technique may also be used for radio-guided surgery. Its use for radio-immunotherapy is under investigation. (authors)

    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.

    Background: While the development of new treatments for aggressive thyroid cancer has advanced in the last 10 years, progress has trailed headways made with other malignancies. A lack of reliable authenticated human cell lines and reproducible animal models is one major roadblock to preclinical testing of novel therapeutics. Existing xenograft and orthotopic mouse models of aggressive thyroid cancer rely on the implantation of highly passaged human thyroid carcinoma lines in immunodeficient mice. Genetically engineered models of papillary and undifferentiated (anaplastic) thyroid carcinoma (PTC and ATC) are immunocompetent; however, slow and stochastic tumor development hinders high-throughput testing. Novel models of PTC and ATC in which tumors arise rapidly and synchronously in immunocompetent mice would facilitate the investigation of novel therapeutics and approaches. Methods: We characterized and utilized mouse cell lines derived from PTC and ATC tumors arising in genetically engineered mice with thyroid-specific expression of endogenous BrafV600E/WT and deletion of either Trp53 (p53) or Pten. These murine thyroid cancer cells were transduced with luciferase- and GFP-expressing lentivirus and implanted into the thyroid glands of immunocompetent syngeneic B6129SF1/J mice in which the growth characteristics were assessed. Results: Large locally aggressive thyroid tumors form within one week of implantation. Tumors recapitulate their histologic subtype, including well-differentiated PTC and ATC, and exhibit CD3+, CD8+, B220+, and CD163+ immune cell infiltration. Tumor progression can be followed in vivo using luciferase and ex vivo using GFP. Metastatic spread is not detected at early time points. Conclusions: We describe the development of the next generation of murine orthotopic thyroid cancer models. The implantation of genetically defined murine BRAF-mutated PTC and ATC cell lines into syngeneic mice results in rapid and synchronous tumor formation. This

    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.

    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.

    Full Text Available Metastasis of uterine cancer to the head and neck is extremely rare. We report what we believe to be the first documented case of endometrioid adenocarcinoma metastasizing to the thyroid gland. An 80-year-old woman was referred to the otolaryngology service with a rapidly growing neck mass. The mass appeared to originate from the thyroid gland. Her clinical presentation was consistent with anaplastic thyroid carcinoma. A tracheostomy was performed. An open biopsy established the diagnosis of moderately differentiated adenocarcinoma, consistent with a gynecologic primary. The patient had undergone a hysterectomy 5 years prior for endometrioid adenocarcinoma. The thyroid tumor histology and immunophenotype corresponded well with her prior endometrial carcinoma, indicating that the thyroid mass was a metastasis from the endometrial primary. Radiotherapy appears to offer good local disease control in this rare case of endometrioid adenocarcinoma metastatic to the thyroid.

    Full Text Available Papillary carcinoma is the most common type of epithelial thyroid cancer in women, especially in the reproductive period, accounting for about 75-80% of well-differentiated cancers at this level. One of its variants, follicular encapsulated thyroid carcinoma, is a well-differentiated malignant tumor with good prognosis which, despite the presence of vascular and capsular invasion, rarely causes metastasis, if fully resected. We present the case of a young patient who presented with dysphagia and a painless cystic nodular lesion of the thyroid, and underwent thyroidectomy. The histopathological diagnosis of the lesion was a challenge, being based on the correlation of clear criteria, given the existence of numerous lesions with follicular pattern in the thyroid.

    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.

    A 66-year-old woman with Pendred's syndrome underwent a partial thyroidectomy when she was 17 years old. At the age of 52 years, she had a second thyroid operation because of hyperthyroidism due to a toxic multinodular goiter with a mediastinal extension consisting of several separate nodules. Five years later a hyperfunctioning metastatic follicular carcinoma was diagnosed histologically. After treatment with radioactive iodine, the patient was well. To the authors' knowledge, this is the first description of a metastatic follicular thyroid carcinoma in Pendred's syndrome and the first report of hyperthyroidism occurring after malignant degeneration of a dyshormonogenetic goiter.

    Thyroid cancer and Graves' disease may present simultaneously in one patient. The incidence of the development of hyperthyroidism from metastatic differentiated thyroid carcinoma is rare. We herein report a case of metastatic follicular carcinoma complicated with Graves' disease after total thyroidectomy. A 57-year-old woman underwent right hemithyroidectomy for follicular carcinoma. Metastatic lesions appeared in the lungs and skull two years after the first surgery, and remnant thyroidectomy was performed for radioactive iodine-131 (RAI) therapy, during which the TSH receptor antibody (TRAb) was found to be negative. The patient was treated with RAI therapy four times for four years and was receiving levothyroxine suppressive therapy. Although radioiodine uptake was observed in the lesions after the fourth course of RAI therapy, metastatic lesions had progressed. Four years after the second surgery, she had heart palpitations and tremors. Laboratory data revealed hyperthyroidism and positive TRAb. She was diagnosed with Graves' disease and received a fifth course of RAI therapy. 131I scintigraphy after RAI therapy showed strong radioiodine uptake in the metastatic lesions. As a result, the sizes and numbers of metastatic lesions decreased, and thyroid function improved. Metastatic lesions produced thyroid hormone and caused hyperthyroidism. RAI therapy was effective for Graves' disease and thyroid carcinoma.

    Abstract The purpose of this study was to investigate the risk factors for central and lateral neck lymph node metastases in papillary thyroid carcinoma (PTC) and multifocal papillary thyroid carcinoma (MPTC), particularly when associated with Hashimoto thyroiditis (HT). A retrospective analysis of 763 consecutive patients who underwent total thyroidectomy with bilateral central neck dissection in the First Affiliated Hospital, College of Medicine, Zhejiang University between October 2011 and October 2014 was conducted. All patients had formal histological diagnoses of HT. Multivariable logistic regression analysis was performed to identify risk factors of neck lymph node metastases. Our study identified 277 PTC patients with HT and showed comparatively low rates of central lymph node metastases (CLNM) compared with the PTC patients without HT (37.2% versus 54.7%, P thyroid peroxidase antibody >140 IU/mL was established as the most sensitive and specific level for the prediction of MPTC based on receiver operating characteristic curve analyses. Thyroid peroxidase antibody, age, tumor size, and multifocality exhibited the ability to predict CLNM in PTC with HT patients with an area under the curve of 81.1% based on a multivariate model. Hashimoto thyroiditis was associated with increased prevalences of multifocality and capsular invasion. In contrast, HT was associated with a reduced risk of CLNM in PTC and MPTC patients, which indicated a potential protective effect. We found that the prognostic prediction model was applicable for predicting multifocality and CLNM in PTC patients with HT. PMID:26871795

    Radiation-induced well-differentiated and poorly differentiated follicular thyroid cancers were transplanted into the intrascapular fat pads of male Fisher 144 rats. The tumors grew in the recipient rats and after a time interval were removed and studied along with normal rat thyroids for lysosomal activity and ultrastructural characteristics. Plasma from experimental and control rats was also studied for lysosomal activity. Rats with radiation-induced thyroid carcinoma had a decrease in growth rate compared with normal rats. There was no significant increase in plasma lysosomal enzymes in the experimental rats. Well-differentiated thyroid carcinomatous tissue showed increased total activities of lysosomal enzymes as well as a difference in subcellular distribution compared with normal and poorly differentiated carcinomatous tissue. Electron microscopy of normal and carcinomatous tissue demonstrated the greatest number of lysosomes in the well-differentiated carcinoma and the fewest in the poorly differentiated carcinoma

    A 70-yr-old woman presented with hyperthyroidism and metastatic follicular carcinoma of the thyroid. The blood level of thyroid stimulating immunoglobulin (TSIg) was elevated. A total thyroidectomy was performed. One month later she remained hyperthyroid. Three weeks after therapy with 218 mCi of I-131 sodium iodide, the patient was euthyroid. Six months after the initial radioiodide therapy, she was again hyperthyroid and was given a second oral treatment dose of I-131 (220 mCi). Five months later, the patient had again become euthyroid. It is likely that initially the woman's metastases were producing sufficient hormone to render her hyperthyroid. After thyroidectomy and two large doses of radioiodide, she has remained euthyroid without having to take exogenous hormone

    It is known that genetic abnormalities in oncogenes and/or tumor suppressor genes promote carcinogenesis. Numerous recent articles, however, have demonstrated that epithelial-stromal interaction also plays a critical role for initiation and progression of carcinoma cells. Furthermore, ionizing radiation induces alterations in the tissue microenvironments that promote carcinogenesis. There is little or no information on epithelial-stromal interaction in thyroid carcinoma cells. The objective of this study was to determine if epithelial-stromal interaction influenced the growth of thyroid carcinoma cells in vivo and in vitro and to determine if radiation had added or interacting effects. Normal Fisher rat thyroid follicular cells (FRTL5 cells) and tumorigenic rat thyroid carcinoma cells (FRTL-Tc cells) derived from FRTL5 cells were employed. The cells were injected into thyroids or subcutaneously into left flanks of rats alone or in combination with skin-derived fibroblasts. In groups of rats, fibroblasts were irradiated with 0.1 or 4 Gy x-ray 3 days before inoculation. In vitro growth of FRTL-Tc and FRTL-5 cells were evaluated using the fibroblast-conditioned medium and in a co-culture system with fibroblasts. The in vivo experiments demonstrated that FRTL-Tc cells injected intrathyroidally grew faster than those injected subcutaneously, and that admixed fibroblasts enhanced growth of subcutaneous FRTL-Tc tumors, indicating that the intrathyroidal milieu, particularly in the presence of fibroblasts, confer growth-promoting advantage to thyroid carcinoma cells. This in vivo growth-promoting effect of fibroblasts on FRTL-Tc cells was duplicated in the in vitro experiments using the fibroblast-conditioned medium. Thus, our data demonstrate that this effect is mediated by soluble factor(s), is reversible, and is comparable to that of 10% fetal bovine serum. However, normal FRTL5 cells did not respond to the fibroblast-conditioned medium. Furthermore, high- and low

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

    There are several useful diagnostic examinations for thyroid disease. The diagnostic value of CT in thyroid disease is still controvertial, although CT has become a routine clinical examination, since the plain CT does not always identify tumors accurately. In this paper, we introduce for the first time thyroid lymphography-computed tomography (TLG-CT) which may improve the diagnostic value of CT. The technique combines CT with thyroid lymphography. We performed TLG-CT in 92 patients with various thyroid diseases and 20 normal controls and classified the radiological features into the following 6 types: entire (normal thyroid); moth-eaten (Hashimoto's thyroiditis); defect (follicular adenoma and adenomatous goiter); lobate (papillary carcinoma); localized (various thyroid diseases); and extrathyroid defect (parathyroid tumor). In addition, we examined the relationship between TLG-CT type and the macroscopic appearance of the cut surface of the thyroid and lymph node metastasis in 20 patients with papillary carcinoma. The results suggest that papillary TLG-CT type carcinomas have a high incidence of lymph node metastasis. Our preliminary results suggest that TLG-CT is a potentially valuable diagnostic tool in the detection of thyroid disease and the assessment of the pathologic diagnosis as well as lymph node metastasis.

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

    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

    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.

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected. Therefore, it is important carefully examine patients with Hashimoto's thyroiditis

    Physical and cytogenetic estimates of the whole-body radiation doses have been compared in 11 patients receiving large doses of iodine-131 for the treatment of thyroid carcinoma. The physical estimate was based on the measurement of thyroid uptake, of the plasma activity variation, and of urinary activity. The cytogenetic estimate was obtained from the analysis of chromosome aberrations in peripheral blood lymphocytes. Good agreement between the estimates was observed in patients whose thyroid glands had previously be ablated by radioiodine. In patients who had varying degrees of thyroid function, there were considerable differences between the estimates with the cytogenetic value always being higher. It is suggested that these differences might be due in part to non-uniform irradiation of lymphocytes by local sources of activity in the thyroid and in the liver. (author)

    Dual malignancy is rare in adolescents. Dual malignancy with the second malignancy of thyroid is rare. No association has been reported between dysgerminoma of ovary and carcinoma thyroid in medical literature. Despite a thorough PubMed search (key words — Papillary carcinoma of thyroid, metachronous, dysgerminoma ovary), we were unable to find a previous reported case of metachronous papillary carcinoma of thyroid (PTC) following dysgerminoma of the ovary. After surgery, the patient is being regularly followed up for recurrence/development of new primary. We report this unusual and rare case in a 17-year-old female patient. PMID:27904567

    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.

    Lingual thyroid cancer is a rare entity with a paucity of literature guiding methods of surgical treatment. Its location presents anatomic challenges with access and excision. We present a case of T4aN1b classical variant papillary thyroid carcinoma of the lingual thyroid that was removed without pharyngeal entry. We also present a review of the literature of this rare entity and propose a treatment algorithm to provide safe and oncologic outcomes. Our review of the literature found 28 case reports of lingual thyroid carcinoma that met search criteria. The trans-cervical/trans-hyoid approach was the most frequently used and provides safe oncologic outcomes. This was followed by the transoral approach and then lateral pharyngotomy. Complications reported across the series include 1 case of pharyngocutaneous fistula associated with mandibulotomy and postoperative respiratory distress requiring reintubation or emergent tracheostomy in 2 patients. The location of lingual thyroid carcinoma can be variable, and surgical management requires knowledge of adjacent involved structures to decrease the risk of dysphagia and airway compromise. In particular, for cases where there is extensive loss to swallowing mechanisms, laryngeal suspension can allow the patient to resume a normal diet after treatment.

  4. False positive results using calcitonin as a screening method for medullary thyroid carcinoma

    Full Text Available The role of serum calcitonin as part of the evaluation of thyroid nodules has been widely discussed in literature. However there still is no consensus of measurement of calcitonin in the initial evaluation of a patient with thyroid nodule. Problems concerning cost-benefit, lab methods, false positive and low prevalence of medullary thyroid carcinoma (MTC are factors that limit this approach. We have illustrated two cases where serum calcitonin was used in the evaluation of thyroid nodule and rates proved to be high. A stimulation test was performed, using calcium as secretagogue, and calcitonin hyper-stimulation was confirmed, but anatomopathologic examination did not evidence medullar neoplasia. Anatomopathologic diagnosis detected Hashimoto thyroiditis in one case and adenomatous goiter plus an occult papillary thyroid carcinoma in the other one. Recommendation for routine use of serum calcitonin in the initial diagnostic evaluation of a thyroid nodule, followed by a confirming stimulation test if basal serum calcitonin is showed to be high, is the most currently recommended approach, but questions concerning cost-benefit and possibility of diagnosis error make the validity of this recommendation discussible.

    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.)

    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.

    Preoperative accumulation of radioiodine in metastases of thyroid carcinoma and its association with hyperthyroidism are uncommon. We report a case of 58-year-old woman with follicular thyroid carcinoma revealed by thyrotoxicosis caused by a hot nodule, and bilateral pulmonary uptake of I-131 before total thyroidectomy. Despite four ablative doses of I-131, bone metastases were identified and the patient died 42 month after the initial diagnosis. (authors)

    Postmortem examination of the carcass of an approximately 10-year-old male Red-eared slider ( Trachemys scripta elegans ) was performed. The thyroid gland was enlarged, showed follicular structure, and shifted the base of the heart caudally. Histology revealed differently shaped and sized follicles in the thyroid gland. Based on the macroscopic appearance and histopathological changes of the thyroid gland, the pathological process was established as a papillary-cystic carcinoma. Neoplasia of the endocrine organs, especially of the thyroid gland, is rare in reptiles. The current case seems to be the first report of thyroid carcinoma in a Red-eared slider.

    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)

    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

    There are several useful diagnostic examinations for thyroid disease. The diagnostic value of CT in thyroid disease is still controvertial, although CT has become a routine clinical examination, since the plain CT does not always identify tumors accurately. In this paper, we introduce for the first time thyroid lymphography-computed tomography (TLG-CT) which may improve the diagnostic value of CT. The technique combines CT with thyroid lymphography. We performed TLG-CT in 92 patients with various thyroid diseases and 20 normal controls and classified the radiological features into the following 6 types: entire (normal thyroid); moth-eaten (Hashimoto's thyroiditis); defect (follicular adenoma and adenomatous goiter); lobate (papillary carcinoma); localized (various thyroid diseases); and extrathyroid defect (parathyroid tumor). In addition, we examined the relationship between TLG-CT type and the macroscopic appearance of the cut surface of the thyroid and lymph node metastasis in 20 patients with papillary carcinoma. The results suggest that papillary TLG-CT type carcinomas have a high incidence of lymph node metastasis. Our preliminary results suggest that TLG-CT is a potentially valuable diagnostic tool in the detection of thyroid disease and the assessment of the pathologic diagnosis as well as lymph node metastasis.

    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.

  13. "MONOCLONAL ANTIBODY HBME-1 USEFULNESS IN DIFFERENTIATION OF BENIGN NEOPLASM AND DIFFERENTIATED THYROID CARCINOMA"

    Directory of Open Access Journals (Sweden)

    M. Mokhtari

    2005-05-01

    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.

    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.

    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.

    The usefulness of using peroxidase-labelled Ulex europaeus agglutinin I for the staining of small vessels and capillaries in the capsule of thyroid tumours is demonstrated. With this procedure the scanning for small tumour deposits in those vessels and, consequently, the diagnosis of follicular carcinoma of the thyroid is facilitated.

    Differentiated thyroid cancers account for 1% of all neoplasias but only for 2.3% of thyroid nodules. A particular condition is represented by the association with hyperthyroidism, which is found in about 7% of cases. Even more rarely may be themselves cause of thyrotoxicosis. In the present paper, the case of a 66-year old male patient, bearing a recently appeared goiter, referred to us for suspicion of lung cancer and hyperthyroid symptoms, is reported. Among appropriate investigations, the finding of high titer of thyroglobulin in the aspiration needle and cytology examination suggested that thyroid lesion was primary and not metastatic, while scintiscan with J-131 isotope showed that excess of thyroid hormones was just due to it; histological diagnosis was of papillary carcinoma. As to the pathogenesis of the neoplasma during hyperthyroidism, a causal role of thyroid stimulating auto-antibodies has been suggested in the cases associated with Graves' disease, absent in our patient, which could elicitate cancer progression in the mean time. Interestingly, activating mutation of thyroid hormone receptor (TSH-r) gene has been demonstrated in a hyperfunctioning differentiated cancer. Notwithstanding the unexpected clinical behaviour may appear very rare, molecular biology studies on aspiration biopsies (FNAB) will allow, in the future, to better define the neoplastic nature of some hot nodules. In personal opinion, this particular pathology must be attently searched both for its implications in the prognosis and therapeutic strategy and because it could be less rare than generally considered up to now.

    The purpose of the study was to compare morphologic and ultrasonic pictures of the thyroid. The study included 42 children with thyroid cancer exposed to ionizing radiation after the Chernobyl accident. All children were operated on during 1990-1994 yy. This study has shown that diffuse sclerosing variant of papillary carcinoma (PC) occurred more frequently in patients with higher absorbed doses to the thyroid. This variant of PC was rarely found at pT1 stage, besides, diffuse sclerosing PC was more frequently accompanied by bilateral and median metastases (``pure`` PC and follicular variant of PC). Biometry of thyroid carcinoma showed a wider spread of neoplastic process in diffuse sclerosing PC than in pure papillary carcinoma. The patients with diffuse sclerosing PC had the second operation more frequently than those with follicular PC. 14 refs, 5 tabs.

    Papillary thyroid carcinoma (PTC) is a common affliction of the thyroid gland, accounting for 70% to 80% of all thyroid cancers, whereas mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland is uncommon. The simultaneous occurrence of both malignancies is extremely rare. We report the case of a patient with both PTC and MALT lymphoma in the setting of Hashimoto thyroiditis. An 81-year-old female patient was first admitted with goiter and hoarseness, which was attributed to an ultrasonographic thyroid nodule. Subsequent fine-needle aspirate, interpreted as suspicious of papillary thyroid cancer, prompted total thyroidectomy. MALT lymphoma was an incidental postsurgical finding, coexisting with PTC in the setting of Hashimoto thyroiditis. Although the development of MALT lymphoma is very rare, patients with longstanding Hashimoto thyroiditis should undergo careful surveillance for both malignancies.

    In most cases, the histopathologic and cytologic distinction between Graves' disease and papillary thyroid carcinoma is relatively easy, but on occasion Graves' disease may simulate a thyroid papillary carcinoma. For example, papillary fronds with fibrovascular cores may be present in both Graves' disease and papillary carcinoma. p27kip1 (p27) is a cyclin-dependent kinase inhibitory protein that has been shown to be an independent prognostic factor in a variety of human tumors. Our previous studies of p27 expression in hyperplastic and neoplastic endocrine lesions showed that the level of p27 was quite different in these two conditions. To determine if this distinction could also be made between Graves' disease and papillary carcinoma, we analyzed expression of p27 and other cell cycle proteins in a series of cases of Graves' disease with papillary hyperplasia and a series of papillary thyroid carcinomas. Formalin-fixed paraffin-embedded tissues from 61 randomly selected patients with thyroid disease, including 29 cases of Graves' disease with papillary architectural features and 32 cases of papillary carcinoma, were analyzed for expression of p27, Ki-67, and DNA topoisomerase II alpha (topo II alpha) by immunostaining. The distribution of immunoreactivity was analyzed by quantifying the percentage of positive nuclei that was expressed as the labeling index (LI) plus or minus the standard error of the mean. The papillary hyperplasia of Graves' disease had a p27 LI of 68.2 +/- 3.1 (range, 24 to 88), whereas papillary carcinomas had a LI of 25.6 +/- 2.5 (range, 12 to 70) (P hyperplasia in Graves' disease and papillary carcinoma. These results indicate that p27 protein expression is significantly higher in papillary hyperplasia of Graves' disease compared to papillary carcinoma, which may be diagnostically useful in difficult cases.

    Twenty-five reports in the medical literature of thyroid carcinomas which were detected after radioiodide therapy for hyperthyroidism were reviewed. These cases did not show a usual characteristic of radiation-associated tumors, namely a long latency period. That is, in 8/25 the latency period was under five years, and the mean latency was only 7.3 years. Further, there was no relationship between latency and age at treatment, or between latency and the dose of radioiodide employed. In 15/25 of the cases, there were known thyroid nodules. Three of the patients had thyroiditis (which itself has a correlation with thyroid carcinoma), and one individual had prior head and neck external radiation. There was no substantiating evidence that radioiodide treatment for hyperthyroidism was the cause of these thyroid carcinomas

    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

    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.)

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.

    Objective The increasing incidence of thyroid nodules demands identification of risk factors for malignant disease. Several studies suggested the association of higher TSH levels with cancer, but influence of 25-hydroxyvitamin D (25OHD) is controversial. This study aimed to identify the relationship of thyroid cancer with higher TSH levels and hypovitaminosis D and to evaluate their influence on prognostic characteristics of papillary thyroid carcinomas (PTC). Methods We retrospectively evaluated 433 patients submitted to thyroidectomy for thyroid nodules. Patients were categorized according to quartiles of TSH and 25OHD levels. Clinicopathological features were analyzed. Results Subjects with thyroid carcinomas were more frequently male and younger compared to those with benign disease. Their median TSH levels were higher and adjusted odds-ratio (OR) for cancer in the highest-quartile of TSH (> 2.4 mUI/mL) was 2.36 (1.36–4.09). Although vitamin D deficiency/insufficiency was prevalent in our cohort (84%), no significant differences in 25OHD levels or quartile distribution were observed between benign and malignant cases. Among 187 patients with PTC, analyses of prognostic features revealed increased risk of lymph nodes metastases for subjects with highest-quartile TSH levels (OR = 3.7, p = 0.029). Decreased 25OHD levels were not overtly associated with poor prognosis in PTC. Conclusions In this cross-sectional cohort, higher TSH levels increased the risk of cancer in thyroid nodules and influenced its prognosis, particularly favoring lymph nodes metastases. On the other hand, no association was found between 25OHD levels and thyroid carcinoma risk or prognosis, suggesting that serum 25OHD determination may not contribute to risk assessment workup of thyroid nodules.

    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

    A study of incidence rates of thyroid carcinoma was conducted in Olsztyn province from 1 January 1994 to 31 December 2003 within its former boundaries, in spite of Poland's new administrative division. The criteria for register entry were as follows: residence in Olsztyn province, newly-diagnosed case of thyroid malignancy in the given calendar year, and histopathological verification in the Department of Anatomical Pathology of the District Specialist Hospital in Olsztyn. The study of selected risk factors comprised patients included in the register of thyroid carcinoma. For that purpose a questionnaire was prepared which covered information about the Chernobyl accident: place of residence, time of carcinoma diagnosis after the accident, and iodine prophylaxis during the accident. The control group consisted of 589 healthy subjects selected based on age and place of residence. In the years 1993-2003, 462 (395 women and 67 men) cases of thyroid cancer were registered. The questionnaire study comprised 297 patients with thyroid carcinoma and 589 healthy subjects. Study subjects from both the affected and control groups stayed mainly in their place of residence during the Chernobyl accident (97.28% v. 94.24%). Thyroid carcinoma was diagnosed on average 13.58 ± 2.61 years after irradiation. There were no significant differences in iodine prophylaxis during the Chernobyl accident. Lugol's solution was given to 31% of patients and 34% of healthy respondents. 1. It cannot be stated that the Chernobyl disaster had any influence on the incidence rate of thyroid carcinoma in the province of Olsztyn. 2. Iodine prophylaxis using Lugol's solution could have an influence on lack of significant increase of the thyroid carcinoma incidence rate in the age group 1-18 years.

    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 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 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.

    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

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

    Aim: Elevated iodine intake is a serious problem in the diagnostic and therapeutic application of 131 iodine in patients with differentiated thyroid cancer. Therefore, iodine avoidance is necessary 3 months in advance. Additionally, endogenous stimulation requires withdrawal of thyroid hormone substitution for 4 weeks. Exogenous stimulation using recombinant human TSH (rhTSH) enables the continuous substitution of levothyroxine, which contains 65.4% of its molecular weight in iodine. Thus, a substantial source of iodine intake is maintained during exogenous stimulation. Although this amount of stable iodine is comparable to the iodine intake in regions of normal iodine supply, it may reduce the accumulation of radioiodine in thyroid carcinoma tissue. The aim of this study was to assess the iodine excretion depending on different ways of stimulation. Methods: Iodine excretion was measured in 146 patients in the long term follow up after differentiated thyroid carcinoma. Patients were separated into 2 groups, those on hormone withdrawal (G I) and rhTSH-stimulated patients on hormone substitution (G II). Results: Iodine excretion was significantly lower in hypothyroid patients (G I, median 50 μg/l, range: 25-600 μg/l) than in those under levothyroxine medication (G II, median 75 μg/l, 25-600 μg/l, p [de

    Primary squamous cell carcinomas of the thyroid gland are extremely rare, comprising about 1% of thyroid malignancies. Although squamous cell carcinomas are readily identified as such on aspiration cytology in the majority of cases, the differentiation of primary versus metastatic tumour might not always be easy. Herein, we report three cases of squamous cell carcinomas involving the thyroid gland. Fine needle aspiration cytology (FNAC) was performed in three patients with a thyroid mass using standard guidelines. Smears were stained with Diff-Quik and Papanicolaou stains. Two patients were male and one was female, aged 59, 45 and 35 years, respectively. In all three patients a thyroid mass was present. FNAC smears in all cases showed cytological features of squamous cell carcinoma including keratinization and necrosis. After clinical and cytological correlation, one case appeared to be primary, one case metastatic, and in the third case no additional clinical information or biopsy follow-up was available for further characterization. Because primary squamous cell carcinoma of the thyroid is a rare finding, metastatic squamous cell carcinoma should always be excluded first. Metastatic disease usually presents in the setting of widespread malignancy, therefore a dedicated clinical and radiological investigation is necessary in these cases. In both clinical scenarios the patient's prognosis is poor. © 2010 Blackwell Publishing Ltd.

    The majority of thyroid tumors are classified as papillary (papillary thyroid carcinomas; PTCs) or follicular neoplasms (follicular thyroid adenomas and carcinomas; FTA/FTC) based on nuclear features and the cellular growth pattern. However, classification of the follicular variant of papillary thyroid carcinoma (FVPTC) remains an issue of debate. These tumors contain a predominantly follicular growth pattern but display nuclear features and overall clinical behavior consistent with PTC. In this study, we used comparative genomic hybridization (CGH) to compare the global chromosomal aberrations in FVPTC to the PTC of classical variant (classical PTC) and FTA/FTC. In addition, we assessed the presence of peroxisome proliferator-activated receptor-gamma (PPARG) alteration, a genetic event specific to FTA/FTC, using Southern blot and immunohistochemistry analyses. In sharp contrast to the findings in classical PTC (4% of cases), CGH analysis demonstrated that both FVPTC (59% of cases) and FTA/FTC (36% of cases) were commonly characterized by aneuploidy (P = 0.0002). Moreover, the pattern of chromosomal aberrations (gains at chromosome arms 2q, 4q, 5q, 6q, 8q, and 13q and deletions at 1p, 9q, 16q, 17q, 19q, and 22q) in the follicular variant of PTC closely resembled that of FTA/FTC. Aberrations in PPARG were uniquely detected in FVPTC and FTA/FTC. Our findings suggest a stronger relationship between the FVPTC and FTA/FTC than previously appreciated and support further consideration of the current classification of thyroid neoplasms.

    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.

    Prognostic value of prophylactic level VII nodal dissection in papillary thyroid carcinoma has been highlighted. A total of 27 patients with papillary thyroid carcinoma with N0 neck underwent total thyroidectomy with level VI and VII nodal dissection through same collar neck incision. Multicentricity, bilaterality, extrathyroidal extension, level VI and VII lymph nodes were studied as separate and independent prognostic factors for DFS at 24 months. 21 females and 6 males with a mean age of 34.6 years old, tumor size was 5-24 mm. (mean 12.4 mm.), multicentricity in 11 patients 2-4 foci (mean 2.7), bilaterality in 8 patients and extrathyroidal extension in 8 patients. Dissected level VI LNs 2-8 (mean 5 LNs) and level VII LNs 1-4 (mean 1.9). Metastatic level VI LNs 0-3 (mean 1) and level VII LNs 0-2 (mean 0.5). Follow-up from 6-51 months (mean 25.6) with 7 patients showed recurrence (3 local and 4 distant). Cumulative DFS at 24 months was 87.8% and was significantly affected in relation to bilaterality (p-valueVII positive ((p-valueVII nodal involvement. Level VII prophylactic nodal dissection is an important and integral prognostic factor in papillary thyroid carcinoma. A larger multicenter study is crucial to reach a satisfactory conclusion about the necessity and safety of this approach.

    Follicular carcinoma of the thyroid in association with hyperthyroidism is rare. The malignant lesion may remain occult for a long time. Certain clinical and cytologic features may be helpful in raising the alarm. An elderly male with a history of occupational exposure to X rays, long-standing toxic multinodular goiter and clinical hyperthyroidism presented with a rapidly enlarging mass in the neck. Cytologic smears showed a prominent microfollicular pattern, scanty colloid, anisonucleosis and nuclear overlapping. The noteworthy feature was the presence of marginal vacuoles. The cytologic diagnosis of follicular neoplasm with highly suggestive malignancy was made. Subsequently, multiple pulmonary nodules provided radiologic evidence of possible metastatic spread. This case report demonstrates the rare association of follicular carcinoma of the thyroid with hyperthyroidism and analyzes certain high-risk clinical and cytologic features to be considered in the follow-up of long-standing hyperfunctioning multinodular goiter.

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

    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

    Full Text Available Context: The neural cell adhesion molecule CD56 is an antigen important for the differentiation of the follicular epithelium. Recent studies have reported low or absent expression of CD56 in papillary thyroid carcinoma (PTC and its presence in normal thyroid tissue, benign thyroid lesions, and most follicular non-PTC tumors. Aim: We wish to estimate the value of CD56 in the differentiation of PTC (including follicular variant-PTC [FV-PTC] from other nontumoral lesions and follicular thyroid neoplasias. Settings and Design: This was a retrospective, case–control study. Subjects and Methods: We analyzed the expression of CD56 in normal thyroid follicular tissue, 15 nonneoplastic thyroid lesions (nodular hyperplasia, Graves' disease, and chronic lymphocytic thyroiditis/Hashimoto, and 38 thyroid follicular cell neoplasms (25 cases of PTC. The immunohistochemical reactions were performed on sections stained with anti-CD56 antibody. Statistical Analysis Used: We used the Chi-square test, values of P< 0.05 being considered statistically significant. Risk analysis was applied on these studied groups, by calculating the odds ratio (OR value. Results: Our results indicated that CD56 immunoexpression had differentiated PTC from benign nonneoplastic lesions (P = 0.002, as well as from follicular neoplasias (P = 0.046. There were no significant differences regarding CD56 expression between FV-PTC and classical PTC (P = 0.436. The immunoexpression of CD56 has differentiated PTC from other thyroid non-PTC lesions (P < 0.001, with 26.4 OR value. Conclusions: CD56 has been proved to be a useful marker in the diagnosis of PTC, including FV-PTC. Its absence can help differentiate FV-PTC from other thyroid nodules with follicular patterns.

    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

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

    Full Text Available 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.

    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

    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)

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

    Full Text Available Renal cell carcinoma is known to cause metastasis to unusual sites, which can be both synchronous or metachronous. Thyroid gland is a rare site for metastasis, but when it occurs, renal cell carcinoma is the most common primary neoplasm. We report the case of a 81-year-old female patient who had a significant medical history of right clear cell renal carcinoma with adrenal metastasis. She underwent right radical nephrectomy and adrenalectomy followed by radiofrequency ablation of left adrenal metastasis and systemic chemotherapy with sunitinib. Eleven years later, she presented with dysphagia and was found to have distal esophageal adenocarcinoma. On imaging, there was incidental detection of a left renal mass lesion and a right thyroid nodule, which on histopathology and immunohistochemistry were confirmed to be clear cell carcinoma of renal origin.

    Ectopy is the most common embryogenetic defect of the thyroid gland, representing between 48 and 61% of all thyroid dysgeneses. Persistence of thyroid tissue in the context of a thyroglossal duct remnant and lingual thyroid tissue are the most common defects. Although most cases of ectopic thyroid are asymptomatic, any disease affecting the thyroid may potentially involve the ectopic tissue, including malignancies. The prevalence of differentiated thyroid carcinoma in lingual thyroid and thyroglossal duct cyst is around 1% of patients affected with the above thyroid ectopies. We here review the current literature concerning primary thyroid carcinomas originating from thyroid tissue on thyroglossal duct cysts and lingual thyroid. Copyright © 2016 SEEN.

  18. The etiology of thyroid tumours

    Bellabarba, Diego

    1983-01-01

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

    1997-01-01

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

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

    This report documents 3 pediatric papillary thyroid carcinoma cases with associated Hashimoto thyroiditis. In all 3 cases, hypoechoic nodules accompanied by multiple echogenic spots were noted on sonography of the thyroid. Hashimoto thyroiditis was suspected on the basis of positive thyroid autoantibody test results and pathologic examinations of thyroidectomy specimens, which revealed chronic thyroiditis with lymphocytic infiltration as the background of papillary thyroid carcinoma development. The potential for papillary carcinoma development warrants close follow-up, and meticulous sonographic examinations must be performed in children with Hashimoto thyroiditis. © 2014 by the American Institute of Ultrasound in Medicine.

    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, "1"3"1I 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 "1"3"1I 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.

    Unilateral invasion of the internal jugular vein (IJV) after subtotal thyroidectomy caused by local recurrence of papillary thyroid carcinoma is extremely rare. We report a case of papillary thyroid carcinoma which invades IJV with hypervascular tumor thrombus. We report a case of a 52-year-old woman with a history of previous thyroid operation who presented with a 2-month history of a painless, growing, hard, solitary mass on the left side of the neck. Clinical examination revealed also ipsilateral cervical lymphadenopathy. Radiological examination showed a necrotic and cystic mass arising from the operated area extending and invading the left jugular vein wall with hypervascular tumor thrombus. Cytological examination of the mass confirmed a papillary thyroid carcinoma (PTC) and enlarged metastatic lymph nodes. Therefore, total thyroidectomy with left neck dissection and segmental resection of the left internal jugular vein were performed, and the tumor thrombus was cleared successfully. Invasion of IJV with hypervascular tumor thrombosis is an extremely rare condition in papillary thyroid carcinoma. Thrombosis of IJV is probably underdiagnosed. Early-stage diagnosis is important for long-term survival rates

    Background: To exam the effect of radioactive iodine treatment for thyroid remnant ablation and/or distant metastasis. A total of 134 well-differentiated thyroid cancer patients with cervical lymphnode metastasis at the time of diagnosis were retrospectively reviewed at Chang Gung Medical Center in Taiwan from 1977 to 1995. Methods: Among them, 126 cases were papillary carcinomas and 8 cases were follicular carcinomas. The mean age was 37.0 ± 14.6 years old. After the operation, 127 (95 %) patients received 131 I treatment (mean dose: 146.6 ± 109.5 mCi, range 30 - 550 mCi) and long-term follow-up. The mean follow-up period is 5.9 ± 3.9 yrs. All patients were restage at the end of 1995. Clinical biochemical results were also analyzed. Results: Among 127 cases who received postoperative radioactive iodine treatment, the majority of cases (92.5 % in papillary ca. vs. 57.1 % in follicular ca.) improved to stage I, 11 (8.6 %) cases remained on the same disease and stages. 13 cases (10.2 %, 10 papillary and 3 follicular) deteriorated to stage III or IV. However, in the non-treatment group, only 33.3 % of papillary carcinoma patients improved to stage I and 16.7 % of the patients remained as stage II. There were 5 cases (3.7 %) of mortality. Two cases with stage IV papillary carcinomas died of metastatic or recurrent malignancy, and the other 2 cases with stage I or III papillary carcinomas died of tracheal cancer or valvular heart disease. One patient with stage IV follicular carcinoma died of cerebral vascular accident. Conclusions: Radioactive iodine ( 131 I) treatment plays a significant role in the management of well-differentiated thyroid carcinoma patients with cervical lymphnode metastasis. The effect of postoperative 131 I treatment on papillary carcinoma was better than that on follicular carcinoma. The optimal dosage and frequency of radioactive iodine treatment warrant further study. (author)

    The purpose of this study was to investigate the risk factors for central and lateral neck lymph node metastases in papillary thyroid carcinoma (PTC) and multifocal papillary thyroid carcinoma (MPTC), particularly when associated with Hashimoto thyroiditis (HT).A retrospective analysis of 763 consecutive patients who underwent total thyroidectomy with bilateral central neck dissection in the First Affiliated Hospital, College of Medicine, Zhejiang University between October 2011 and October 2014 was conducted. All patients had formal histological diagnoses of HT. Multivariable logistic regression analysis was performed to identify risk factors of neck lymph node metastases.Our study identified 277 PTC patients with HT and showed comparatively low rates of central lymph node metastases (CLNM) compared with the PTC patients without HT (37.2% versus 54.7%, P thyroid peroxidase antibody >140 IU/mL was established as the most sensitive and specific level for the prediction of MPTC based on receiver operating characteristic curve analyses. Thyroid peroxidase antibody, age, tumor size, and multifocality exhibited the ability to predict CLNM in PTC with HT patients with an area under the curve of 81.1% based on a multivariate model.Hashimoto thyroiditis was associated with increased prevalences of multifocality and capsular invasion. In contrast, HT was associated with a reduced risk of CLNM in PTC and MPTC patients, which indicated a potential protective effect. We found that the prognostic prediction model was applicable for predicting multifocality and CLNM in PTC patients with HT.

    Thyroid hormone (TH) transporters are expressed in thyrocytes and most play a role in TH release. We asked whether expression of the monocarboxylate transporter 8 (MCT8) and the L-type amino acid transporters LAT2 and LAT4 is changed with thyrocyte dedifferentiation and in hyperfunctioning thyroid tissues. Protein expression and localization of transporters was determined by immunohistochemistry in human thyroid specimen including normal thyroid tissue (NT, n  = 19), follicular adenoma (FA, n  = 44), follicular thyroid carcinoma (FTC, n  = 45), papillary thyroid carcinoma (PTC, n  = 40), anaplastic thyroid carcinoma (ATC, n  = 40) and Graves' disease (GD, n  = 50) by calculating the 'hybrid' (H) score. Regulation of transporter expression was investigated in the rat follicular thyroid cell line PCCL3 under basal and thyroid stimulating hormone (TSH) conditions. MCT8 and LAT4 were localized at the plasma membrane, while LAT2 transporter showed cytoplasmic localization. MCT8 expression was downregulated in benign and malignant thyroid tumours as compared to NT. In contrast, significant upregulation of MCT8, LAT2 and LAT4 was found in GD. Furthermore, a stronger expression of MCT8 was demonstrated in PCCL3 cells after TSH stimulation. Downregulation of MCT8 in thyroid cancers qualifies MCT8 as a marker of thyroid differentiation. The more variable expression of LATs in distinct thyroid malignancies may be linked with other transporter properties relevant to altered metabolism in cancer cells, i.e. amino acid transport. Consistent upregulation of MCT8 in GD is in line with increased TH release in hyperthyroidism, an assumption supported by our in vitro results showing TSH-dependent upregulation of MCT8. © 2017 European Society of Endocrinology.

    The multiple neurofibromatosis is an autosomal dominant hereditary disease associated to malignant schwannoma in about 3% of the cases and very rarely to others cancers. The study provides information on the case of a 32 year-old woman who suffers from this disease and presented two synchronous cancers: a papillary carcinoma of thyroid and a malignant schwannoma of the chest wall. The thyroid tumour was managed with hemithyroidectomy, hormonotherapy and radiotherapy, and the lesion of the thoracic wall was treated with local radical resection application of Marlex mesh and rotation of a musculocutaneous flap of the dorsal muscle. A review of the literature on the clinical aspects of this association and the surgical techniques employed to cover the defect of the chest wall is presented. (authors)

    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

    Full text: Purpose: To look at the clinical presentation and treatment outcome of patients with papillary thyroid carcinoma (PTC) and those with follicular thyroid carcinoma (FTC) in our institution. Methods: The records of all patients with papillary or follicular thyroid carcinoma seen at our institution were retrieved. Patients were excluded from this study if they underwent thyroid surgery outside a teaching hospital or presented to us more than 6 months post surgery, had deep external beam therapy (DXT) following surgery or a follow up of less than 3 years. This left clinical data and treatment outcomes of 140 patients available for a retrospective review. Results: One hundred and seventeen patients were females and 23 were males (5.1:1) with a median follow up of 10,5 years. The differences noted were as follow: there was a higher incidence of PTC than FTC (2.9:1); patients with PTC were younger at presentation (mean age 40 vs 49); more patients with PTC had metastases (60% vs 40%) and were much younger at presentation as compared to those with FTC (mean age 38 vs 63); at presentation eighty percent of FTC metastases were localized in bones whereas 60% of PTC metastases went to the lungs and 36% were confined to local lymph nodes. Similar pattern was found in those who developed metastases later. A significant percentage of ablation failure (41% vs 59% success rate) after the first high dose (2.96-3.7 GBq) of radioactive iodine (RAI) was noted. The total success rate increased to 80% after the second dose of RAI (3.7- 7.4 GBq). The majority of the patients ablated by the second dose had PTC and most had inadequate initial surgery ranging from unilateral lobectomy (10 patients), subtotal thyroidectomy (10 patients), and bilateral lobar resection (1 ). Conclusion: The predominance of PTC over FCT may indicate the conversion to an iodine repletion state in the country as a whole. Similar studies in other regions seem necessary to support this statement. The high

    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

    This study aimed to assess the relationship between coexisting lymphocytic thyroiditis and T-N stages of papillary thyroid carcinoma (PTC) by histopathological analysis. The study included 653 patients who underwent thyroid surgery for PTC at our hospital. Each case was classified as either Hashimoto's thyroiditis (HT), non-Hashimoto type of lymphocytic thyroiditis (NHLT), or normal according to the histopathology of thyroid parenchyma. Patient age, gender, surgical modality, location, T stage, N stage, multifocality and bilaterality were compared according to the histopathology. The prevalence of coexisting lymphocytic thyroiditis was 25.8% (169/653); HT (7.5%, 49/653) and NHLT (18.3%, 120/653). There were no significant differences in T stage, N stage, multifocality and bilaterality with regard to coexisting lymphocytic thyroiditis, regardless of whether HT and NHLT were considered collectively or discretely. Primary tumor size (p thyroiditis did not differ from those with normal parenchyma in terms of T stage, N stage, multifocality and bilaterality.

    Full Text Available Abstract Follicular thyroid carcinoma (FTC tends to metastasize to remote organs rather than local lymph nodes. Separation of FTC from follicular thyroid adenoma (FTA relies on detection of vascular and/or capsular invasion. We investigated which vascular markers, CD31, CD34 and D2-40 (lymphatic vessel marker, can best evaluate vascular invasion and why FTC tends to metastasize via blood stream to remote organs. Thirty two FTCs and 34 FTAs were retrieved for evaluation. The average age of patients with FTA was 8 years younger than FTC (p = 0.02. The female to male ratio for follicular neoplasm was 25:8. The average size of FTC was larger than FTA (p = 0.003. Fourteen of 32 (44% FTCs showed venous invasion and none showed lymphatic invasion, with positive CD31 and CD34 staining and negative D2-40 staining of the involved vessels. The average number of involved vessels was 0.88 ± 1.29 with a range from 0 to 5, and the average diameter of involved vessels was 0.068 ± 0.027 mm. None of the 34 FTAs showed vascular invasion. CD31 staining demonstrated more specific staining of vascular endothelial cells than CD34, with less background staining. We recommended using CD31 rather than CD34 and/or D2-40 in confirming/excluding vascular invasion in difficult cases. All identified FTCs with vascular invasions showed involvement of venous channels, rather than lymphatic spaces, suggesting that FTCs prefer to metastasize via veins to distant organs, instead of lymphatic vessels to local lymph nodes, which correlates with previous clinical observations.

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

    Nonanaplastic follicular cell-derived thyroid carcinoma (NAFCTC) includes differentiated- (DTC) and poorly differentiated thyroid carcinoma (PDTC). DTC has an excellent prognosis, while PDTC is situated between DTC and anaplastic carcinomas. Short-term studies suggest that PDTC patients diagnosed only on tumor necrosis and/or mitosis have a prognosis similar to those diagnosed according to the TURIN proposal. The purpose of this study was to evaluate prognosis for NAFCTC based on long-term follow-up illuminating the significance of tumor necrosis and mitosis. A cohort of 225 patients with NAFCTC was followed more than 20 years. Age, sex, distant metastasis, histology, tumor size, extrathyroidal invasion, lymph node metastasis, tumor necrosis and mitosis were examined as possible prognostic factors. Median follow-up time for patients alive was 28 years (range 20-43 years). Age, distant metastasis, extrathyroidal invasion, tumor size, tumor necrosis and mitosis were independent prognostic factors in multivariate analysis for overall survival (OS). In disease specific survival (DSS) age was not significant. Using only necrosis and/or mitosis as criteria for PDTC the 5-, 10- and 20-year OS for DTC was 87, 79 and 69%, respectively. In DSS it was 95, 92 and 90%. For PDTC the 5-, 10- and 20-year OS was 57, 40 and 25%, respectively. In DSS it was 71, 55 and 48%. Tumor necrosis and mitosis are highly significant prognostic indicators in analysis of long time survival of nonanaplastic follicular cell-derived thyroid carcinoma indicating that a simplification of the actually used criteria for poorly differentiated carcinomas may be justified.

    Full Text Available Background. 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.

    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.)

    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

    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.

    Medullary carcinoma of the thyroid, a malignant neoplasm of para follicular C cells, represent about 5-10% of thyroid tumors. The symptoms are related to local invasion and hormonal secretion. The clinical course is variable, from indolent cases to extremely aggressive. Many radionuclide imaging have been described to locate metastasis of medullary cancer. Tl-201 and Tc-99m (V)DMS A showed to be useful in the evaluation o persistent elevated serum calcitonin levels. On the other hand, the use of the 131 I-Mibg, that is the isotope more used, has not been demonstrating efficiency in identifying metastasis. Our objective is to report a case of a patient with medullary thyroid carcinoma in which the follow-up use DMS A(V) demonstrated a recurrence no identified for other methods. A 34-year-old man had a diagnosis of medullary thyroid carcinoma and has submitted a total thyroidectomy and neck lymph node dissection. He presented elevated serum calcitonin levels and DMS A(V) scintigraphy demonstrated focal area of pathologic uptake at the medline of the neck, but the surgical exploration was negative. He persisted with high calcitonin levels and it was used a new DMS A(V). On this occasion he was submitted to the radio-guided surgery that located the recurrence and it was confirmed with anatomo-pathologic exam. This case allowed to demonstrate that the use of radionuclide associated to the gamma-probe is promising, allowing a precise surgical approach. (author)

    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.

    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)

    Standard therapy has not been established for thyroid cancer when a thyroidectomy is contraindicated due to systemic disease. Herein, we reported a patient who had hypertrophic cardiomyopathy and papillary thyroid carcinoma treated by radiofrequency ablation because of inability to tolerate a thyroidectomy. Radiofrequency ablation can be used to treat thyroid cancer when surgery is not feasible, although the long-term outcome needs further observation.

    A patient with a superior mediastinal mass on an admission chest radiograph was initially evaluated by an 131 I thyroid scan which failed to demonstrate a substernal thyroid. However, the tomographic 67 Ga scan clearly showed an abnormal uptake in the area corresponding to the mass lesion on radiographic examination. Subsequent resection and biopsy of the substernal mass revealed a poorly differentiated follicular carcinoma with foci of anaplastic carcinoma. The differential diagnosis of the anterior mediastinal mass and the usefullness of the tomographic gallium scan are briefly discussed

Methods: Clinical data from 1,198 patients diagnosed with PTC (n=578 and control subjects (n=620 with benign thyroid disease (ie, thyroid nodule disease, benign thyroid diseases [BTD] in Yunnan province were analyzed retrospectively. Results: The mean patient age was lower for PTC than for BTD. Positive ratios of thyroid peroxidase antibody, thyroglobulin antibody (TGAb, and thyrotrophin receptor antibody (TRAb were higher in PTC than in BTD patients. The ratio of PTC coexisting with Hashimoto’s thyroiditis (HT or with lymphocytic thyroiditis was higher than that of BTD. The number of patients whose age at menarche was ≤13 years, who had given birth to less than or equal to two children, or who were in premenopause were higher in the PTC than in the BTD group. Multivariate conditional logistic regression analyses revealed that age >45 years, nodal size >1 cm, and elevated TG levels were protective factors against PTC. Abnormally elevated TGAb and TRAb levels were independent risk factors for PTC in females

    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.

    The purpose of this study was to define and characterize the thyroid tumor-draining lymph nodes in genetically engineered mice harboring thyroid-specific expression of oncogenic Braf V600E with and without Pten insufficiency. After intratumoral injection of methylene blue, the lymphatic drainage of the thyroid gland was visualized in real time. The thyroid gland/tumor was resected en bloc with the respiratory system for histological analysis. Although mice harboring Braf V600E mutations were smaller in body size compared with their wild-type (WT) littermates, the size of their thyroid glands and deep cervical lymph nodes were significantly larger. Additionally, the tumor-draining lymph nodes showed increased and enlarged lymphatic sinuses that were distributed throughout the cortex and medulla. Tumor-reactive lymphadenopathy and histiocytosis, but no frank metastases, were observed in all mice harboring Braf V600E mutations. The tumor-draining lymph nodes undergo significant structural alterations in immunocompetent mice, and this may represent a primer for papillary thyroid carcinoma (PTC) metastasis. © 2017 Wiley Periodicals, Inc.

    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.

    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.

    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

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

    Full Text Available Introduction: Follicular thyroid carcinoma (FTC is the second most common type of thyroid cancer, after papillary thyroid carcinoma (PTC, accounting for approximately 10% of all malignant thyroid tumours with higher predilection for women. FTC demonstrates capsular and/or vascular invasion and often presents with distant metastasis in 20%–30% of cases via the haematogenous spread. FTC tends to commonly metastasize to the lung and bone although other sites have been identified. Kidney metastasis from a primary FTC however is rare and has not been widely reported. We report a case of FTC with metastatic to the kidney in a patient presenting with a large left pelvic mass. Case presentation: A 54-year-old, Malay, lady with underlying hypertension and dyslipidaemia presented with chronic left pelvic pain since 1 year ago, following a fall during a recent vacation trip. She also experienced significant unintentional weight loss for the past few months. Clinical examination noted an ill-defined palpable firm mass over the left inner thigh. Pelvic radiograph showed a solitary ill-defined osteolytic lesion at the left superior and inferior pubic rami with cortical destruction. MRI of the pelvis showed a large lobulated enhancing expansile mass originating from the left pubic bone measuring 10.0(AP × 6.0(W × 8.5(CC cm, hypointense signal on T1W and hyperintense signal on T2W. The mass infiltrated adjacent bony structures and muscles. Patient subsequently undergone core biopsy of the left pelvic mass and histopathological examination (HPE noted metastatic follicular thyroid carcinoma. An ultrasound examination of the thyroid showed a multinodular goitre with suspicious nodule in the left thyroid gland. Pre-operative contrast-enhanced computed tomography (CECT showed primary thyroid carcinoma with nodal, lung and bone metastases with possible left kidney involvement. Total thyroidectomy was ensued and follicular thyroid carcinoma was confirmed based on

    In this study, we describe a case of papillary carcinoma in a 15-year-old girl who presented with a hyperfunctioning (hot) thyroid nodule and discuss it in the context of current management guidelines for patients with thyroid nodules. In adults, hot nodules rarely require cytologic or histologic evaluation, and hyperthyroidism is often treated with radioiodine (131I). However, in children and adolescents, the malignancy rate for nodules (both cold and hot) is higher and surgery is often necessary. Surgery may serve as a therapy, as well as a diagnostic tool, to treat hot nodules in children and adolescents.

  2. New Molecular Targeted Therapy and Redifferentiation Therapy for Radioiodine-Refractory Advanced Papillary Thyroid Carcinoma: Literature Review

    Kai-Pun Wong

    2012-01-01

    Full Text Available Although the majority of papillary thyroid carcinoma could be successfully managed by complete surgical resection alone or resection followed by radioiodine ablation, a small proportion of patients may develop radioiodine-refractory progressive disease which is not amenable to surgery, local ablative treatment or other treatment modalities. The use of FDG-PET/CT scan for persistent/recurrent disease has improved the accuracy of restaging as well as cancer prognostication. Given that patients with RAI-refractory disease tend to do significantly worse than those with radioiodine-avid or non-progressive disease, an increasing number of phase I and II studies have been conducted to evaluate the efficacy of new molecular targeted drugs such as the tyrosine kinase inhibitors and redifferentiation drugs. The overall response rate of these drugs ranged between 0–53%, depending on whether the patients had been previously treated with these drugs, performance status and extent of disease. However, drug toxicity remains a major concern in administration of target therapies. Nevertheless, there are also ongoing phase III studies evaluating the efficacy of these new drugs. The aim of the review was to summarize and discuss the results of these targeted drugs and redifferentiation agents for patients with progressive, radioiodine-refractory papillary thyroid carcinoma.

    2015-01-01

    Full Text Available We report the case of a 74-year-old man with a four-year history of right nephrectomy for clear cell renal carcinoma (CCRC who was diagnosed with hyperthyroidism. On ultrasound (US, a 5 cm solid isohypoechoic nodule with intranodular vascularization was found in the left thyroid lobe. The nodule was deemed autonomous on T99mc thyroid scan. Methimazole was started and serum thyroid hormone levels quickly normalized; euthyroidism was maintained with a very low dosage of antithyroid drug. Over time, compressive symptoms and local pain occurred and US revealed growth of the nodule. Total thyroidectomy was performed and the combined histological and immunohistochemical evaluation deemed the nodule compatible with metastasis of CCRC; on 2-year follow-up, no tumor relapse was ascertained. In patients with a history of cancer, a thyroid nodule, even if hyperfunctioning, must be suspected of being a metastasis and investigated. Hot nodules, which are largely benign, may be vulnerable to metastatic colonization owing to their rich vascularization. In these cases, surgery may be curative.

    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.

    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.

    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.

    To evaluate the outcome of resection of simultaneous discrete bilateral mobile thyroid gland carcinomas (TGCs) in dogs. Retrospective case series. 15 dogs with resected simultaneous discrete bilateral mobile TGCs. Medical records (from 1994 to 2010) were searched for dogs with the appropriate diagnosis and treatment. Information collected included signalment, clinical signs, diagnostic test results, tumor mobility (mobile tumor identified by movement ≥ 1 cm in all planes during palpation), complications, adjuvant treatments, and outcome. Mobile, discrete, bilateral TGCs were removed in all dogs. Among the 15 dogs, complete parathyroidectomies were necessary in 9; parathyroid tissue was reimplanted in 4 and preserved in 2. Complications included hemorrhage and laryngeal nerve trauma, but without serious consequences. Thirteen dogs received calcitriol with or without supplemental calcium after surgery. In the immediate postoperative period, hypocalcemia developed and was corrected in 11 dogs. At the end of the study, 7 dogs continued to receive calcitriol with or without supplemental calcium, and 8 dogs required long-term thyroid hormone treatment. Six dogs received adjuvant chemotherapy. Local tumor recurrence or de novo distant metastasis was not detected at each dog's last follow-up examination. Median survival time was 38.3 months. Three dogs were lost to follow-up, 8 survived (4.3 to 77 months after surgery), and 4 died of unrelated causes. In dogs with TGCs undergoing bilateral thyroid lobectomies, a successful outcome can be expected, even when parathyroid gland tissue cannot be preserved. The role of adjuvant chemotherapy in treatment outcome was not clearly defined.

    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.

    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.

    Purpose: To assess diagnostic accuracy for tumor invasion of surrounding organs by measurement of tumor circumferences on MR images in patients with differentiated thyroid carcinomas. Material and Methods: Surgical and MR imaging findings in 50 patients with differentiated thyroid carcinoma (43 primary, 7 recurrent lesions) were retrospectively reviewed. The degrees of circumference of tumor encroachment to the organs were measured, and the measurements and morphologic diagnosis of tumor invasion made by a head and neck radiologist were compared with surgical and pathologic findings using receiver operating characteristic curves. Results: Diagnosis of tumor invasion by the radiologist was superior to the measurements of the carotid artery and cartilage, while the reverse was true for the trachea and esophagus. However, no statistical differences were noted between them for each structure. Optimal thresholds for tumor invasion were 90 deg or more for the cartilage (94% accuracy) and esophagus (86% accuracy), 135 deg or more for the trachea (86% accuracy), and 225 deg or more for the carotid artery (90% accuracy). Conclusion: Tumor invasion was more accurately diagnosed by measurement of tumor circumferences of each organ on MR images

    Full Text Available We report the case of a 45-year-old man who presented with a 4-year history of midline neck swelling associated with recent onset respiratory distress. Local examination showed a lobulated diffuse thyroid enlargement. A subtotal thyroidectomy was performed. The right lobe weighed 225 g and the left lobe weighed 130 g. Multiple sections from both the lobes revealed diffuse infiltration of the stroma by mature adipose tissue. There was no evidence of amyloid deposits or papillary carcinoma. A final diagnosis of diffuse lipomatosis of the thyroid gland was rendered. Lipomatosis or adenolipomatosis of the thyroid gland is an extremely rare entity. The various differential diagnoses of fat in the thyroid include benign entities like amyloid goiter, adenolipoma, lymphocytic thyroiditis, intrathyroid thymic or parathyroid lipoma and malignant tumors like liposarcoma and encapsulated papillary carcinoma. Adequate clinical details and a thorough histopathological examination are mandatory for diagnosis.

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

    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.

    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

    Squamous cell carcinoma of thyroid is an uncommon, very aggressive neoplasm, having a poor prognosis and poor response to chemotherapy and radiotherapy. Surgery is the initial treatment of choice, although it often presents as a widespread disease at the time of diagnosis, usually with cervical swelling that causes most of the symptoms due to local infiltration or metastasis. Local infiltration from adjacent tumour and metastatic disease needs to be excluded from other primary epidermoid carcinomas, in order to make a correct diagnosis. This also requires the typical cytokeratin pattern seen in histological studies. The case is presented of a 53 year-old man with a medical history of hepatocarcinoma, with a cervical hypermetabolic lesion detected in an 18 F-FDG PET/CT performed to exclude widespread disease. The follow-up of this lesion with this technique and its usefulness is also described. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

    To examine the efficacy of I-131 therapy in decreasing recurrence rates after surgery for differentiated thyroid carcinoma, a research tool called meta-analysis was used. Data were pooled from five published studies which evaluated recurrences following at least sub-total thyroidectomy with or without I-131 ablation of remnants. Of 1332 patients managed surgically only 202 (15%) developed recurrences compared to 36 of 339 (11%) treated with radioiodine. This difference was statistically significant at p<.05. When a separate analysis of only those studies which directly compared the two modes of management was conducted, recurrence rates for patients treated by surgery alone was higher at 18% (185 of 1034) compared with those who had subsequent I-131 therapy with a rate of 9% (27 of 297). This difference was again significant at p <.001. This meta-analysis strongly suggests that the use of I-131 for ablation of post-surgical thyroid remnants significantly reduces recurrence rates in patients with differentiated thyroid carcinoma.

    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.

    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.

    Full Text Available We report the case of a 29-year old female who was evaluated because of a thyroid tumor. The initial pathological classification was an insular thyroid carcinoma. There was strong involvement in the neck, mediastinum and lungs. Three years after receiving specific therapy for her thyroid neoplasia, she developed a Cushing syndrome and liver lesions suggestive of metastases from the primary tumor. A review of the previous pathological material revealed a medullary thyroid carcinoma producing ACTH, instead of the insular carcinoma. Based on this case a review of the literature is presented.

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

    Full Text Available 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.

    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.

    To analyze sonographic findings suggesting central lymph node metastasis of papillary thyroid carcinoma and to evaluate the influence of associated chronic lymphocytic thyroiditis on the diagnostic performance of sonography for predicting central lymph node metastasis. A total of 124 patients (101 female and 23 male; mean age, 47.5 years; range, 21-74 years) underwent sonographically guided fine-needle aspiration in central lymph nodes from January 2008 to July 2011. Sonographic features of size, shape, margin, thickening of the cortex, cortical echogenicity, presence of a hilum, cystic changes, calcification, and vascularity of enlarged lymph nodes were analyzed before fine-needle aspiration and classified into 2 categories (probably benign and suspicious). Sonographic findings were correlated with the pathologic diagnosis and associated chronic lymphocytic thyroiditis. Receiver operating characteristic curve analysis was performed to assess the diagnostic performance of sonography for predicting central lymph node metastasis according to the associated thyroiditis. Fifty-one lymph nodes (39.5%) were malignant, and 73 (60.5%) were benign. On univariate analysis, size, shape, margin, cortical thickening, cortical echogenicity, cystic changes, calcification, and vascularity were significantly different between the benign and metastatic nodes (P thyroiditis-positive patients and 0.971 (95% CI, 0.938-1.000) in negative patients. Eccentric cortical thickening and cortical hyperechogenicity were the sonographic findings predictive of central lymph node metastasis from papillary thyroid carcinoma. The diagnostic performance of sonography for predicting metastasis was superior in chronic lymphocytic thyroiditis-negative patients than in positive patients.

    Full Text Available BackgroundThe ultrasonographic characteristics and difference for various subtypes of papillary thyroid carcinoma (PTC are still unclear. The aim of this study was to compare the ultrasonographic features of PTC according to its subtype in patients undergoing thyroid surgery.MethodsIn total, 140 patients who underwent preoperative thyroid ultrasonography (US and thyroid surgery between January 2016 and December 2016 were included. The ultrasonographic features and the Korean Thyroid Imaging Reporting and Data System (K-TIRADS category of each thyroid nodule were retrospectively evaluated by a single radiologist, and differences in ultrasonographic features according to the PTC subtype were assessed.ResultsAccording to histopathological analyses, there were 97 classic PTCs (62.2%, 34 follicular variants (21.8%, 5 tall cell variants (3.2%, 2 oncocytic variants (1.3%, 1 Warthin-like variant (0.6%, and 1 diffuse sclerosing variant (0.6%. Most PTCs were classified under K-TIRADS category 5. Among the ultrasonographic features, the nodule margin and the presence of calcification were significantly different among the PTC subtypes. A spiculated/microlobulated margin was the most common type of margin, regardless of the PTC subtype. In particular, all tall cell variants exhibited a spiculated/microlobulated margin. The classic PTC group exhibited the highest prevalence of intranodular calcification, with microcalcification being the most common. The prevalence of multiplicity and nodal metastasis was high in the tall cell variant group.ConclusionThe majority of PTCs in the present study belonged to K-TIRADS category 5, regardless of the subtype. Our findings suggest that ultrasonographic features are not useful for distinguishing PTC subtypes.

    Generally, primary differentiated tumours are removed surgically followed by adjuvant radioiodine treatment. The effect and outcome of radioiodine ablation depends on the uptake in the thyroid carcinoma cells. But, about one third of patients with local recurrent thyroid carcinomas or distant metastases do not respond to iodine treatment due to loss of differentiation. Prognosis was impaired if tumour cells are losing the capability for radioiodine uptake due to dedifferentiation. However, several trials have been attempted to induce re-differentiation of tumour cells in order to regain their potential for radioiodine uptake. (orig.)

It has been found in 93.2% papillary, in 3.2% - medullary, in 1% - anaplastic carcinomas. A typical papillary carcinoma was revealed in 11.5%, follicular variant - in 39.0%, solid variant - in 28.1%, diffuse and sclerosing variant - in 3.8%. In cases of solid variant low-differentiated cells prevailed in the tumor, what manifested itself the most obviously by electron microscopic analysis. The thyroid carcinomas studied in children and adolescents of Ukraine are characterized by high invasive properties, that is confirmed by a high percentage (66.5%) of regional metastases

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

    The histological diagnosis is critical for the postsurgical management and follow-up of thyroid malignancies. The differential diagnosis between papillary carcinoma and hyperfunctioning lesions, either with papillary hyperplasia or with a follicular architecture, can create real diagnostic difficulty. The aim of this study was to evaluate the expression of several antibodies considered to be markers of malignancy in malignant and hyperfunctioning thyroid neoplasms and to include the most effective of them in a diagnostic panel. One hundred resected thyroid nodules--58 hyperfunctioning benign lesions and 42 papillary carcinomas (14 follicular variant, 14 macrofollicular variant and 14 classic type)--were immunohistochemically studied for HBME-1, galectin-3, cytokeratin (CK) 19 and RET-proto-oncogene. HBME-1 and galectin-3 showed 92.8% and 89% sensitivity, respectively, and their coexpression was present in 36 out of 42 papillary carcinomas (85.7%) and absent in non-malignant lesions. Their association increased sensitivity to 94.7% and the diagnostic accuracy to 97.9% and involved the highest number of cases (95%) in comparison with two other panels including, respectively, three (HBME-1, galectin-3, CK19) and all four antibodies. An immunohistochemical panel consisting of HBME-1 and galectin-3 can make a correct distinction between malignant and hyperfunctioning thyroid neoplasms with high diagnostic accuracy.

    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.

    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

    Anaplastic thyroid carcinoma (ATC) is an extremely aggressive and rapidly fatal neoplasm. The aim of this study was to identify a limited cell cycle associated protein expression pattern unique to ATC and to correlate that pattern with clinical outcome. This represents one of the largest tissue micro-array projects comparing the cell cycle protein expression data of ATC to other well-differentiated tumors in the literature. Tissue microarrays were created from 21 patients with ATC and an age and gender matched cohort of patients with papillary thyroid carcinoma (PTC). Expression of epidermal growth factor receptor, cyclin D1, cyclin E, p53, p21, p16, aurora kinase A, opioid growth factor (OGF), OGF-receptor, thyroglobulin and Ki-67 was evaluated in a semi-quantitative fashion. Differences in protein expression between the cohorts were evaluated using chi-square tests with Bonferroni adjustments. Survival time and presence of metastasis at presentation were collected. The ATC cohort showed a statistically significant decrease (p cycle with aberrant expression of multiple protein markers suggesting increased proliferative activity and loss of control of cell cycle progression to G₁ phase. These findings support the assertion that ATC may represent the furthest end of a continuum of thyroid carcinoma dedifferentiation.

    Thyroid fine-needle aspiration (FNA) cytology is the primary tool for the diagnostic evaluation of thyroid nodules. BRAF mutation analysis is employed as an ancillary tool in indeterminate cases, as recommended by the American Thyroid Association management guidelines. Hereby, we report the case of a 73-year-old woman who presented an 8-mm-size, ill-defined, left thyroid nodule. FNA resulted "suspicious for papillary thyroid carcinoma". BRAF mutation status was analyzed, and somatic BRAF (V600E) mutation identified. The patient underwent a total thyroidectomy. At histological examination, the nodule was composed of Langerhans cells, admixed with many eosinophils. A final diagnosis of Langerhans cell histiocytosis of the thyroid was made. Our case emphasizes the critical diagnostic pitfalls due to the use of BRAF (V600E) mutation analysis in thyroid FNA. Notably, BRAF (V600E) mutation is common in melanoma, colorectal carcinoma, lung carcinoma, ovarian carcinoma, brain tumors, hairy cell leukemia, multiple myeloma, and histiocytoses. Therefore, in cases of indeterminate FNA with unclassifiable atypical cells BRAF (V600E) mutated, the possibility of a localization of hystiocytosis or a secondary thyroid malignancy should be taken into account.

    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

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC. Keywords: thyroid cancer, thyroid nodule, follicular cell carcinoma, Hurthle cell lesion, minimally invasive HCC

    We experienced eight cases of thyroid tumor diagnosed during pregnancy: four papillary carcinomas, a follicular carcinoma with follicular adenoma, two adenomatous goiters, and a follicular carcinoma. The patients were 18 to 27 (mean 26.5) years of age. These tumors were found during 8 to 27 (mean±SD, 14.9±6.4) week of pregnancy, and two of the carcinomas showed rapid growth in early pregnancy, which pregnancy may facilitate. The study shows that in order to arrest the rapid advancement of the thyroid carcinoma in such patients during pregnancy, an operation should be performed even in pregnancy. In other cases, surgical treatment can be reasonably postponed until after parturition. Palpation, ultrasonography and fine needle aspiration biopsy were useful in diagnosing the tumors. Administration of a therapeutic dose of 131-I isotope was effective in all of our cases after total thyroidectomy. However, careful attention should be paid to avoid unexpected pregnancy before and after this therapy for a period sufficient to ensure complete elimination of the radionuclide effect. (author)

    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.

    Full Text Available Objective: To study the correlation of thyroid papillary carcinoma CEUS characteristics with cancer cell proliferation and invasion. Methods: A total of 128 patients with thyroid papillary carcinoma who received surgical treatment in the hospital between May 2013 and May 2016 were collected, CEUS was used to make clear the peak intensity (PI and area under the curve (AUC of tumor tissue and surrounding normal tissue, and the median of PI and AUC was referred to further divide the patients into high PI group and low PI group as well as high AUC group and low AUC group, 64 cases in each group. Fluorescent quantitative PCR was used to determine proliferation and invasion gene mRNA expression in tumor tissues. Results: PI and AUC levels in tumor tissue were lower than those in surrounding normal tissue; proliferation genes EZH2, Livin, hTERT, HMGA1 and Wip1 mRNA expression of low PI group were higher than those of high PI group, and invasion gene Ki-67 mRNA expression was higher than that of high PI group while P53 and MRP-1 mRNA expression were lower than those of high PI group; proliferation genes EZH2, Livin, hTERT, HMGA1 and Wip1 mRNA expression of low AUC group were higher than those of high AUC group, and invasion gene Ki-67 mRNA expression was higher than that of high AUC group while P53 and MRP-1 mRNA expression were lower than those of high AUC group. Conclusion: Thyroid papillary carcinoma CEUS parameters PI and AUC levels can quantifiably reflect the cancer cell proliferation and invasion activity.

    Full Text Available The thyroid is an unusual site to find cancer metastasis. When it does occur, such cancer spread is often manifested in multiple metastases and generally suggests a poor prognosis. We presented here a 49-year-old woman recently diagnosed with thyroid cancer, who had been treated for stage IIA breast cancer 8 years ago. After radical right thyroidectomy and left subtotal thyroidectomy, her pathological report showed papillary thyroid carcinoma, right thyroid, with concomitant metastatic breast carcinoma. This is the first case of which we are aware involving coexisting thyroid cancer and metastatic breast cancer in the ipsilateral lobe. Moreover, the circumstances of this case show a very unique clinical course compared with previous studies. Given the unusual circumstances of our case, we further discuss the relationship between thyroid cancer and breast cancer.

    Seventy-five patients with medullary thyroid carcinoma (MTC) have been treated at Institut Gustave-Roussy from 1932 to 1979. Of these, 13 patients had distant metastases and received palliative treatment, their median survival was 3 years. Sixty-two patients with MTC limited to the neck received curative treatment: 6 had exclusive external radiotherapy for inoperable disease and 56 were surgically treated: 23 by total thyroidectomy and 33 by partial thyroidectomy. After surgery 29 patients received external radiotherapy for cervical lymph node involvement (25/29) and/or incomplete surgical resection (12/27). The survival rate was 69% at 5 years and 48% at 10 years. The 29 patients who received post-operative cervical radiotherapy had initially more extensive local disease (p<0.05) than the 27 patients treated by surgery alone, nevertheless their survival was slightly higher. No difference in survival rate was observed between patients treated by total thyroidectomy or partial thyroidectomy, among whom only 4 local recurrences occurred. Three of the 6 patients treated with external radiotherapy alone experienced long survival (4, 7 and 10 years) and a fourth is still in clinical remission 4 years after treatment. The effectiveness of chemotherapy in patients with metastases was poor, only one patient out of 6 had a partial remission following a treatment by adriamycin. In the familial form and multiple endocrine neoplasia type II, total thyroidectomy appears to be indicated. In the sporadic cases, partial thyroidectomy is usually sufficient. External radiotherapy is effective in MTC and seems to be able to eradicate small foci of residual tumor; it is indicated when surgical excision is impossible or incomplete

    Full Text Available Abstract Background Thyroid physiology is closely related to oxidative changes. The aim of this controlled study was to evaluate the levels of nutritional anti-oxidants such as vitamin C, zinc (Zn and selenium (Se, and to investigate any association of them with parameters of thyroid function and pathology including benign and malignant thyroid diseases. Methods This controlled evaluation of Se included a total of 1401 subjects (1186 adults and 215 children distributed as follows: control group (n = 687, benign thyroid disease (85 children and 465 adults; malignant thyroid disease (2 children and 79 adults. Clinical evaluation of patients with benign thyroid disease included sonography, scintigraphy, as well as the determination of fT3, fT4, TSH, thyroid antibodies levels, Se, Zn, and vitamin C. Besides the routine oncological parameters (TG, TSH, fT4, ultrasound Se was also determined in the cases of malignant disease. The local control groups for the evaluation of Se levels were taken from a general practice (WOMED as well as from healthy active athletes. Blood samples were collected between 8:00 and 10:30 a.m. All patients lived in Innsbruck. Statistical analysis was done using SPSS 14.0. The Ho stated that there should be no differences in the levels of antioxidants between controls and thyroid disease patients. Results Among the thyroid disease patients neither vitamin C, nor Zn nor Se correlated with any of the following parameters: age, sex, BMI, body weight, thyroid scintigraphy, ultrasound pattern, thyroid function, or thyroid antibodies. The proportion of patients with benign thyroid diseases having analyte concentrations below external reference cut off levels were 8.7% of cases for vitamin C; 7.8% for Zn, and 20.3% for Se. Low Se levels in the control group were found in 12%. Se levels were significantly decreased in cases of sub-acute and silent thyroiditis (66.4 ± 23.1 μg/l and 59.3 ± 20.1 μg/l, respectively as well as in

METHODS: We collected data from 959 patients with nontoxic nodular goiter....... The low PPV might lead to unnecessary thyroid surgery. Thus, the result of serum calcitonin measurement should always be interpreted in the context of other clinical variables. (c) 2009 Wiley Periodicals, Inc. Head Neck, 2009....

    American Thyroid Association (ATA) leadership asked the ATA Thyroid Nodules and Differentiated Thyroid Cancer Guidelines Task Force to review, comment on, and make recommendations related to the suggested new classification of encapsulated follicular variant papillary thyroid carcinoma (eFVPTC) without capsular or vascular invasion to noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). The task force consists of members from the 2015 guidelines task force with the recusal of three members who were authors on the paper under review. Four pathologists and one endocrinologist were added for this specific review. The manuscript proposing the new classification and related literature were assessed. It is recommended that the histopathologic nomenclature for eFVPTC without invasion be reclassified as a NIFTP, given the excellent prognosis of this neoplastic variant. This is a weak recommendation based on moderate-quality evidence. It is also noted that prospective studies are needed to validate the observed patient outcomes (and test performance in predicting thyroid cancer outcomes), as well as implications on patients' psychosocial health and economics.

    Most of the steps involved in the initiation and progression of Hürthle (oncocytic, oxyphilic) cell carcinomas of the thyroid remain unknown. Using differential display and semiquantitative RT-PCR we found, among other alterations, overexpression of the gene encoding the Core I subunit of the complex III of the mitochondrial respiratory chain in a follicular carcinoma composed of Hürthle cells. Similar high levels of Core I gene expression were detected in nine follicular carcinomas (seven with Hürthle cell features), in seven microfollicular adenomas (one with Hürthle cell features) and in one micro/macrofollicular adenoma, in contrast to a lower/normal expression in nine papillary carcinomas (three with Hürthle cell features) and five macrofollicular adenomas (one of which displaying Hürthle cell features). No significative correlation was found between Core I overexpression and the proliferative activity of the lesions. We conclude that Core I overexpression in thyroid tumours is not associated with malignancy, Hürthle cells or proliferative activity. The pathogenetic mechanism linking Core I overexpression to the microfollicular pattern of growth of thyroid tumours remains to be clarified

    We tested the suitability of the chimeric monoclonal anti-human CD44 splice version 6 antibody (cMAb U36) for targeting and visualising human anaplastic thyroid carcinoma with PET. We also performed experiments aimed at elucidating the relation between tumour interstitial fluid pressure (TIFP) and the tumour uptake of antibodies. The affinity and specificity of the cMAb U36 for KAT-4 cells were evaluated in vitro, as was the Na{sup +}/I{sup -} symporter (NIS) expression. Biodistribution studies were performed on KAT-4 carcinoma-bearing mice injected with {sup 124}I-cMAb U36 or free iodine. Biodistribution studies were also performed in animals treated with the specific TGF-{beta}1 and -{beta}3 inhibitor Fc:T{beta}RII, which lowers TIFP. Treated and non-treated animals were scanned by microPET. Cultured human undifferentiated/anaplastic thyroid carcinoma KAT-4 cells expressed low levels of NIS and uptake of free iodine was insignificant. The cMAb U36 expressed an affinity (K{sub D}) of 11 {+-} 2 nM. Tumour radioactivity uptake reached maximum values 48 h after injection of {sup 124}I-cMAb U36 ({proportional_to}22%IA/g). KAT-4 carcinomas were readily identified in all {sup 124}I-immuno-PET images. Radioactivity tumour uptake in Fc:T{beta}RII-treated animals was significantly lower at 24 and 48 h after injection, and five times higher thyroid uptake was also noted. We successfully used {sup 124}I-cMAb U36 to visualise CD44v6-expressing human anaplastic thyroid carcinoma. Given the lack of NIS expression in KAT-4, tumour visualisation is not due to free iodine uptake. Lowering the TIFP in KAT-4 carcinomas did not increase the uptake of mAbs into tumour tissue.

    The Multicentre Study Differentiated Thyroid Cancer (MSDS) collective represents a well defined group of patients with locally aggressive thyroid carcinomas (pT4; AJCC/UICC 1997). The aim of the present study was to compare the survival of patients with minimum and extensive extrathyroidal growth according to the new AJCC/UICC TNM staging system 2009. Patients, methods: The follow-up data of 347 patients were analysed. Patients were reclassified according to the current AJCC/UICC 2009 classification. The event-free and overall survival was evaluated using Kaplan-Meier analysis. In addition, postoperative complications and status of disease were documented. Results: 327 patients were assigned to stage pT3 and 20 patients to stage pT4a, respectively. Median follow-up was 6.1 years (range 0.04-9.8 years). 92.5% of patients reached complete remission. There were 7.8% recurrences in the thyroid bed, in locoregional lymph nodes and/or in distant sites. The overall survival was >98% both in pT3 and pT4a patients (p = n. s.). In contrast, the event-free survival was significantly less favourable in pT4a patients (p < 0.001). Using multivariate analysis the following parameters were significant predictors of event-free survival: histological tumour type, degree of extrathyroidal extension and nodal metastasis (p < 0.05). Conclusions: The MSDS patients with locally aggressive differentiated thyroid cancer showed an excellent overall survival during a median follow-up of 6.1 years. According to the current AJCC/UICC 2009 classification, pT3 patients with minimal extrathyroidal extension revealed a significantly better event-free survival than pT4a patients with extensive extrathyroidal growth.

    The purpose of this study is to compare the rate of local complications resulting from radioiodine ablation of thyroid cancer in patients with a residual intact thyroid lobe to that in patients who had more extensive surgical treatment prior to radioiodine administration. We retrospectively studied 59 patients who had received 131I between 1979 and 1989. The patients were divided into two groups, depending on the extent of their previous surgical thyroid excision. Group 1 comprised 10 patients with a lobectomy or hemithyroidectomy before the ablative radioiodine dose, and Group 2 comprised 49 patients with more extensive thyroid excision (near-total or subtotal thyroidectomy) before the radioiodine treatment. Sixty percent of the 10 patients in Group 1 experienced some degree of neck pain or tenderness following radioiodine ablation of their residual thyroid. In one case, the local reaction was very severe and accompanied by the development of transient hyperthyroidism. There was only a 6% local complication rate in the patients who had undergone more extensive thyroid excision before ablative therapy (p less than 0.001), and none had a severe reaction. Patients with only unilateral surgical excision before radioiodine therapy have a higher rate of local complications than do patients treated with more extensive surgery prior to radioiodine ablation. If radioiodine is to be employed in such patients, they should be informed of this possible complication. Since evidence supports a dose effect in the pathogenesis of the complications, we recommend using a dose of less than 30 mCi for the initial ablation in these patients even though it may be necessary to repeat this dose to complete thyroid ablation.

    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.

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

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

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

    Molecular analysis of cDNA derived from a papillary thyroid carcinoma (PTC) (follicular variant of papillary thyroid carcinoma on histology) which developed in an externally irradiated patient 4 years after exposure identified a portion of the 5' region, exons 1-3, of the rfp gene juxtaposed upstream of the fragment encoding the tyrosine kinase (TK) domain of the ret gene. The fusion gene, termed Δrfp/ret, was the result of a balanced chromosomal translocation t(6;10) (p21.3;q11.2) confirmed by interphase FISH painting, with breakpoints occurring in introns 3 and 11 of the rfp and ret genes, respectively. Both Δrfp/ret and reciprocal ret/rfp chimeric introns had small deletions around breakpoints consistent with presumed misrepair of a radiation-induced double-strand DNA break underlying the rearrangement. No extensive sequence homology was found between the fragments flanking the breakpoints. The fusion protein retained the propensity to form oligomers likely to be mediated by a coiled-coil of the RFP polypeptide as assessed by a yeast two-hybrid system. NIH 3T3 fibroblasts stably transfected with a mammalian expression vector encoding full-length ΔRFP/RET readily gave rise to the tumors in athymic mice suggestive of high transforming potential of the fusion protein. Thus, the Δrfp/ret rearrangement may be causatively involved in cancerogenesis and provides additional evidence of the role of activated ret oncogene in the development of a subset of papillary thyroid carcinoma

    The methylation state of the gene promoter for the receptor of the thyroid stimulating hormone (TSH) in the diagnosis of thyroid tumors of epithelial origin was analyzed. The study was conducted in thyroid tissue obtained from paraffin blocks of different thyroid pathologies (papillary, follicular and undifferentiated carcinoma and follicular adenomas). The work was done by using the DNA modification technique with sodium bisulfite, and polymerase chain reaction was applied to analyze the gene methylation state. Methylation of the promoter for the gene of the TSH receptor was found in the papillary carcinomas (33 of 40; 82.5 %), in 10 undifferentiated carcinomas (100 %), and in 10 of the 15 follicular carcinomas analyzed (66.6 %). No methylation was observed in the 8 follicular adenomas under study. The methylation of the gene for the TSH receptor was proposed as a new diagnostic marker of malignity and as a basis for using demethylating agents together with radioiodine therapy in patients with thyroid cancer of epithelial origin that do not respond to therapy.

    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

    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.

    The relation between thyroid neoplasms and chronic lymphocytic thyroiditis (CLT) is controversial. While it is accepted that focal lymphocytic thyroiditis develops secondarily to malignancy, it is not clear whether diffuse lymphocytic thyroiditis has a tendency to develop into thyroid cancer. The aim of this study was to investigate the relation between CLT and malignant tumours of the thyroid and evaluate the surgical approach to CLT cases. In this study, 917 patients operated on for thyroid diseases were investigated retrospectively. Seventy-seven (8.4%) patients histopathologically diagnosed as having CLT (either non-specific or Hashimoto's thyroiditis) were investigated for any concurrent malignant neoplasm. Fifteen patients in whom CLT and thyroid malignancy were coexisting were included in the study. In the pathological evaluation of 917 cases, malignancy in the thyroid was found in 97 (10.6%) cases. Seventy-seven cases were categorised as CLT. Of these 77, 16 (20.8%) were Hashimoto's thyroiditis (specific CLT) and the other 61 (79.2%) were non-specific CLT. In 15 cases, thyroid malignancy was found to be concurrent with CLT. Of the malignities, nine (60%) were papillary carcinoma, three (20%) medullar carcinoma, one (6.6%) follicular carcinoma, one (6.6%) Hurthle cell carcinoma, and one (6.6%) lymphoma. In our series, the rate of the development of malignancy against the background of CLT was 19.48%, while the rate in the groups without CLT was 9.76%, with a statistically significant difference between the groups (p = 0.008). CLT cases should be evaluated more carefully in terms of malignancy. If a nodule is detected on thyroiditis, the minimal surgical intervention should be lobectomy. Total thyroidectomy should be considered as preferable to subtotal thyroidectomy because of its many advantages such as controlling thyroiditis, removing the probability of reoperation, and hormonal stability.

    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.

    Approximately 35% of follicular thyroid carcinomas harbor a chromosomal translocation that results in expression of a paired box gene 8-peroxisome proliferator-activated receptor γ gene (PPARγ) fusion protein (PPFP). To better understand the oncogenic role of PPFP and its relationship to endogenous PPARγ, we generated a transgenic mouse model that combines Cre-dependent PPFP expression (PPFP;Cre) with homozygous deletion of floxed Pten (PtenFF;Cre), both thyroid specific. Although neither PPF...

  16. Ultra-rare mutation in long-range enhancer predisposes to thyroid carcinoma with high penetrance.

    Directory of Open Access Journals (Sweden)

    Huiling He

    Full Text Available Thyroid cancer shows high heritability but causative genes remain largely unknown. According to a common hypothesis the genetic predisposition to thyroid cancer is highly heterogeneous; being in part due to many different rare alleles. Here we used linkage analysis and targeted deep sequencing to detect a novel single-nucleotide mutation in chromosome 4q32 (4q32A>C in a large pedigree displaying non-medullary thyroid carcinoma (NMTC. This mutation is generally ultra-rare; it was not found in 38 NMTC families, in 2676 sporadic NMTC cases or 2470 controls. The mutation is located in a long-range enhancer element whose ability to bind the transcription factors POU2F and YY1 is significantly impaired, with decreased activity in the presence of the C- allele compared with the wild type A-allele. An enhancer RNA (eRNA is transcribed in thyroid tissue from this region and is greatly downregulated in NMTC tumors. We suggest that this is an example of an ultra-rare mutation predisposing to thyroid cancer with high penetrance.

    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

Computed tomography revealed a mass in the right lobe of the thyroid gland, accompanied with right neck lymphadenectasis and airway deviation caused by tumor compression. Thyroid imaging suggested a thyroid malignant tumor and suspicious lymph node metastasis. Histologically, the tumor was characterized by the tumor cells arranged in small nests or trabeculae with an abundant extracellular mucoid matrix. The tumor cells formed diffuse invasion among thyroid follicles. In the peripheral regions, prominent signet-ring-cells formed a sheet-like structure and extended into the extrathyroidal fat tissue. The tumor cells were diffusely positive for thyroid transcription factor-1 (TTF-1 and PAX8, while they were focally positive for pan-cytokeratin (AE1/AE3 and weakly expressed thyroglobulin. Results: Based on the histological features and immunohistochemical profile, a diagnosis of primary mucinous carcinoma of the thyroid gland with signet-ring-cell differentiation was rendered.Conclusion: Using a panel of immunohistochemical markers may be helpful for differential diagnosis and for determining whether the tumor is primary or not.

    To clarify possible role of cysteine cathepsin H, B and L in the proteolytic processes that contribute to the progression of tumor growth in the thyroid, we studied their activity in lysosomes isolated from the tissue of papillary carcinomas. It was shown that for these enzymes there is a dependence of the changes in their activity on a number of biological characteristics of the tumors. Thus, the sharp increase in the activity ofcathepsin H observed in lysosomes of tissue carcinomas category T2 and T3, with intra-and ekstrathyroid and lymphatic invasion of tumor cells. An increase in the activity of cathepsin B is set in the lysosomes of tissue heterogeneous follicular structure, especially in the presence of solid areas, in comparison with typical papillary tumors and in the lysosomes of tissue carcinomas in intrathyroid and cathepsin L-at extrathyroid invasion. A common feature of the enzymes is to increase the activity of cathepsins in lysosomes of tissue nonencapsulated papillary carcinomas. These enzymes probably do not take part in the invasion of tumor cells into blood vessels and in the mechanisms of tumor metastasis to regional lymph nodes. The latter shows no changes in the activity of cathepsins in lysosomes of tissue carcinomas category N1. The results indicate the different role of cathepsin H, B and L in thyroid carcinogenesis, where each enzyme has its specific function.

    Over 80% of all thyroid cancers are diagnosed in the United States of papillary carcinoma type and have been more common in women than in men. Thyroids can be in childhood, but is almost always seen in adults between the ages of 30 and 50 years. The cause of this cancer is unknown. The intervention of a genetic defect may occur. Differentiated thyroid tumors (both papillary and follicular) are susceptible curable. A total of 13 criteria systems are managed, among which the most frequent are: - Age, degree, tumor extension, size; -Age, metastasis, tumor size and size; - Metastasis, age for presentation, degree of surgical resection, extrathyroidal invasion and size. The survival rate for papillary thyroid cancer has been excellent; more than 95% of adults with this type of cancer have survived at least 10 years. The prognosis is best for patients younger than 40 years and for those with smaller tumors. Some methods of diagnosis before the appearance of a suspicious nodule have included an ultrasound, BAAF, gammagraphy, among others. The best way to choose which has been the best surgical method at the time of definitive treatment was determined in this review. (author) [es

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

    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)

    Medullary carcinoma of the thyroid, a malignant neoplasm of para follicular C cells, represent about 5-10% of thyroid tumors. The symptoms are related to local invasion and hormonal secretion. The clinical course is variable, from indolent cases to extremely aggressive. Many radionuclide imaging have been described to locate metastasis of medullary cancer. Tl-201 and Tc-99m (V)DMS A showed to be useful in the evaluation o persistent elevated serum calcitonin levels. On the other hand, the use of the 131 I-Mibg, that is the isotope more used, has not been demonstrating efficiency in identifying metastasis. Our objective is to report a case of a patient with medullary thyroid carcinoma in which the follow-up use DMS A(V) demonstrated a recurrence no identified for other methods. A 34-year-old man had a diagnosis of medullary thyroid carcinoma and has submitted a total thyroidectomy and neck lymph node dissection. He presented elevated serum calcitonin levels and DMS A(V) scintigraphy demonstrated focal area of pathologic uptake at the medline of the neck, but the surgical exploration was negative. He persisted with high calcitonin levels and it was used a new DMS A(V). On this occasion he was submitted to the radio-guided surgery that located the recurrence and it was confirmed with anatomo-pathologic exam. This case allowed to demonstrate that the use of radionuclide associated to the gamma-probe is promising, allowing a precise surgical approach. (author)

  4. HABP2 G534E Variant in Papillary Thyroid Carcinoma.

    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.

    The therapeutic effects of external beam radiation to bone or lymph-node metastatic lesions of thyroid cancer were evaluated in 11 patients. These 11 cases included four male and seven female patients ranging in age from 44 to 69 years (mean age 54 years), were treated by 4MV-Xray irradiation. Thyroid surgery had been performed in all patients. The thyroid tumors were classified histologically as papillary carcinoma in 3 patients and follicular carcinoma in 8. Following surgical total thyroidectomy, thyroid ablation and/or therapy with I-131 was performed in 8 patients with follicular carcinoma. Using a 4MV-Xray external beam, a total dose of 54 to 68 Gy (mean dose 62 Gy) was delivered to 28 metastatic lesions including 2 lymph nodes and 26 bones, although an 82-Gy total dose was used for one lymph node. All patients underwent follow-up for more than 8 years. Ten of the 11 patients died, 6 of thyroid cancer and 4 of other diseases. Two of them suffered anaplastic transformation of differentiated thyroid carcinoma and died. The survival term was 0.2 to 8.6 years (mean 4.9 years) after initial external radiotherapy. Local irradiation with a curative dose was able to control most of the lesions in the 11 patients (29 lesions with the exception of 2 cases showing anaplastic transformation). In some patients, pain relief was obtained although tumor size measured by CT did not reveal marked regression. External beam radiation therapy with a curative dose was thought to be beneficial for patients with metastatic lesions of thyroid cancer as slow-growing and having relatively long survival period of patients.

    Full text: The surgery department of Central Hospital no.1 operated on 1690 thyroid disease patients in last 7 years (2000-2007). Patients' ages were 9-80 years. Female : Male ratio 10 : 1. In the last years morbidity is changed, Diffuse toxic Goiter has decreased, Thyroid nodule and cancer has increased. During last 7 years we have operated 164 patients for thyroid mass. 69 cases (51.54%) of them were thyroid carcinoma. In this 69 cases include Anaplastic carcinoma 3, Papillary carcinoma 36, follicular carcinoma 30 cases. 80 percent patients from thyroid cancer cases were diagnosed in pre-operative period, 20 percent were diagnosed in inter and post-operation period. For thyroid cancer cases we made the following operations: - Total thyroidectomy 20 cases, Hemithyroidectomy 30 cases, Hemithyroidectomy 29 cases. After operation 49 patients were sent for radioactive I-131 treatment and 3 cases which recurred, were operated a second time. In the treatment of DTG, there has been a decrease in the number of surgeries, while great increase in the use of I-131. From 1990 to 1999 have been done 1307 operations, because of thyroid disease: - 580 (44.37%) for DTG, 636 (48.66%) for thyroid nodule, 37 ( 2.83%) for thyroid cancer. From 2000 to 2007 we have conducted 1608 operations, because of thyroid disease: 473 (29.41%) for DTG, 919 (57.15%) for thyroid nodule and 134 (8.33%) for thyroid cancer. All operations were done by O.V.Nicolaev's method. (intracapsular resection). Conclusion: 1. the numbers of thyroid cases which have been treated by operation is changing. There are an increasing number of cases of Thyroid nodule and thyroid cancer. 2. There is need to improve preoperative diagnostics. 3. Combination of surgery treatment and radioactive I131 treatment gave good results for thyroid cancer. (author)

    The thyroid carcinoma is a frequent illness that can reach until 60% of the total of patients assisted in the head and neck consultation. Most of the carcinomas are well differentiated and they can be of the papillar (CPT) or follicular (CFT) type. El basic treatment is surgical and the procedure class impacts in the survival free of illness. The patients that are not managed with complementary treatments to the surgery, like they are the suppression and the iodine therapy, they have bigger possibility of local and regional relapse. In this article epidemic data they are analyzed on the relapses as well as of the advantages of the complementary handling of the well-differentiated carcinoma of thyroid (CBT), additionally, the methods diagnoses are commented for detection of the relapses and the treatment of the same ones. A case managed in the Cancerology National Institute, it discuss finally (INC) with recurrent illness for CPT

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

    Few studies on radiation protection recommendation for patients leaving hospitalization area after thyroid carcinoma treatment with iodine-131 are based on experimental determination of effective half life. The aim of this work was to calculate times of adhesion to restrictions for patients using one dose rate measurement at 30 cm the last day, just before leaving hospital. Dose rate measurements were achieved every day at two localizations (abdomen mid trunk and neck) during hospitalization. Data were fitted by a monoexponential or a biexponential model in order to derive the effective half life. We considered 7 exposure states between patient and neighboring. We showed, according to our realistic scatter state, a dose rate variation inversely proportional to the distance from patient. Effective half life is equal to 16 ± 6 h whatever the measurement localization. Thus the times of adhesion to restrictions is never greater than 2 days after 3 days of hospitalization. A simple table is given to allow the computation of restrictions times according to the dose rate measurement before the patient is discharged. This protocol is applied in our institution and gives whole satisfaction as far as the ALARA principle and the patient information are concerned. (author)

    Percutaneous image-guided procedures, largely based on thermal ablation, are at present under investigation for achieving a nonsurgical targeted cytoreduction in benign and malignant thyroid lesions. In several uncontrolled clinical trials and in two randomized clinical trials, laser ablation has demonstrated a good efficacy and safety for the shrinkage of benign cold thyroid nodules. In hyperfunctioning nodules, laser ablation induced a nearly 50% volume reduction with a variable frequency of normalization of thyroid-stimulating hormone levels. Laser ablation has been tested for the palliative treatment of poorly differentiated thyroid carcinomas, local recurrences or distant metastases. Laser ablation therapy is indicated for the shrinkage of benign cold nodules in patients with local pressure symptoms who are at high surgical risk. The treatment should be performed only by well trained operators and after a careful cytological evaluation. Laser ablation does not seem to be consistently effective in the long-term control of hyperfunctioning thyroid nodules and is not an alternative treatment to 131I therapy. Laser ablation may be considered for the cytoreduction of tumor tissue prior to external radiation therapy or chemotherapy of local or distant recurrences of thyroid malignancy that are not amenable to surgical or radioiodine treatment.

    Follicular thyroid adenoma (FTA) precedes follicular thyroid carcinoma (FTC) by definition with a favorable prognosis compared to FTC. However, the genetic mechanism of FTA to FTC progression remains unknown. For this, it is required to disclose FTA and FTC genomes in mutational and evolutionary perspectives. We performed whole-exome sequencing and copy number profiling of 14 FTAs and 13 FTCs, which exhibited previously-known gene mutations (NRAS, HRAS, BRAF, TSHR and EIF1AX) and copy number ...

    Studies of thyroid cancer related to the Chernobyl accident have focused on children as they are the most vulnerable group with the highest risk of developing radiation-associated cancer. In contrast, our research aimed to look at the clinical and pathological features of patients with post-Chernobyl papillary thyroid carcinoma that were 2 years old or less at the time of the Chernobyl accident. The study subjects were patients (n = 359) aged 0 to 2 at the time of the Chernobyl accident and aged ≥19 years at presentation/surgery who were treated in Belarus for papillary thyroid carcinoma during the period 2003-2013. In conventional or oncocytic variant of papillary thyroid carcinoma, the prevalence of extra-thyroidal extension, nodal disease, infiltrative growth or lymphatic vessel invasion was above 50%. These features were less pronounced when compared to tall cell or diffuse sclerosing variants of papillary thyroid carcinoma. The highest frequency of central lymph node metastases was found in patients aged 1-2 years at exposure (P = 0·004). Subjects exposed in utero were characterized by absent/insignificant lymphocytic infiltration around the carcinoma (P = 0·025), predominance of conventional papillary architecture and an association with lymphocytic thyroiditis. A number of features were associated with this group of patients that were very young at the time of radiation exposure. In addition, the incidence and basic characteristics of adult papillary thyroid carcinoma varied depending on the types of exposure conditions. © 2016 John Wiley & Sons Ltd.

    A total of 444 persons were examined for the presence of thyroid nodules on average of 43 years after having been treated with x-rays for cervical tuberculous adenitis. Of this total, 101 subjects had undergone surgery for thyroid nodules: 25 for carcinoma (6%) and 76 for benign nodules (17%). Carcinoma occurred with the same frequency in multinodular and uninodular glands. Because of the uneven age distribution in the current series, it could not be decided whether there was a higher susceptibility of the young thyroid to the induction of thyroid carcinoma or benign nodules. The dosage range for the whole series was 0.40 to 50.90 Gy (40-5090 rad). There was a positive correlation between the absorbed radiation dose and the probability of developing benign and malignant thyroid nodules, even after doses of 20 Gy or more. The risk of developing thyroid carcinoma was equal for men and women, while the female-to-male ratio for benign nodules was 2.9:1, indicating that risk factors associated with females are of less importance in irradiated than in nonirradiated populations. The median latency for carcinoma was 40 years, suggesting that the increased risk of thyroid carcinoma after irradiation remains for the rest of the patient's life

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

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

    Full Text Available Abstract Background Recent studies have shown that the phosphatidylinositol 3-kinase (PI3K signaling pathway is important regulator of many cellular events, including apoptosis, proliferation and motility. PI3K pathway alterations (PIK3CA gene mutations and/or amplification have been observed in various human tumours. In the majority of diagnosed cases, mutations are localized in one of the three "hot spots" in the gene, responsible for coding catalytic subunit α of class I PI3K (PIK3CA. Mutations and amplification of PIK3CA gene are characteristic for thyroid cancer, as well. Methods The aim of our study was to examine a gene expression level of PIK3CA in fine-needle aspiration biopsy (FNAB thyroid specimens in two types of thyroid lesions, papillary thyroid carcinoma (PTC and non-toxic goitre (NTG. Following conventional cytological examination, 42 thyroid FNAB specimens, received from patients with PTC (n = 20 and NTG (n = 22, were quantitatively evaluated regarding PIK3CA expression level by real-time PCR in the ABI PRISM® 7500 Sequence Detection System. Results Significantly higher expression level (RQ of PIK3CA in PTC group has been noted in comparison with NTG group (p Conclusion These observations may suggest role of PIK3CA alterations in PTC carcinogenesis.

    Most publications to date compare outcomes after post-surgical thyroid remnant ablation stimulated by recombinant human thyrotropin (rhTSH) versus thyroid hormone withholding/withdrawal (THW) in low-recurrence risk differentiated thyroid carcinoma (DTC) patients. We sought to perform this comparison in high-risk patients. We retrospectively analyzed ~9-year single-center experience in 70 consecutive adults with initial UICC (Union for International Cancer Control) stage III/IV, M0 DTC undergoing rhTSH-aided (N.=54) or THW-aided (N.=16) high-activity ablation. Endpoints included ablation success and DTC outcome. Assessed ≥1 year post-ablation, ablation success comprised a) no visible scintigraphic thyroid bed uptake or pathological extra-thyroidal uptake; b) undetectable stimulated serum thyroglobulin (Tg) without interfering autoantibodies; c) both criteria. DTC outcome, determined at the latest visit, comprised either 1) "no evidence of disease" (NED): undetectable Tg, negative Tg autoantibodies, negative most recent whole-body scan, no suspicious findings clinically, on neck ultrasonography, or on other imaging; 2) persistent disease: failure to attain NED; or 3) recurrence: loss of NED. After the first ablative activity, ablation success by scintigraphic plus biochemical criteria was 64.8% in rhTSH patients, 56.3% in THW patients (P=NS). After 3.5-year versus 6.2-year median follow-up (P<0.05), DTC outcomes were NED, 85.2%, persistent disease, 13.0%, recurrence, 1.9%, in the rhTSH group and NED, 87.5%, persistent or recurrent disease, 6.3% each, in the THW group (P=NS). In patients with initial stage III/IV, M0 DTC, rhTSH-aided and THW-assisted ablation were associated with comparable remnant eradication or DTC cure rates.

    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.

    We illustrate a case of synchronous malignant solitary fibrous tumor of the thoracic cavity, and widely invasive thyroid Hurthle cell carcinoma. The Hurthle cell carcinoma was found to harbor distinct areas of malignant solitary fibrous tumor. This is a unique case of tumor-to-tumor metastasis that, to the best of our knowledge, has not been previously reported.

    We compared three different scintigraphic techniques for the localization of neck recurrences and metastases in seven patients with medullary thyroid carcinoma one month to eight years after the first surgical intervention. Three successive scintigraphic studies were performed in five patients (6 x 3 studies) within two weeks using 201Tl chloride, 111In-labeled F(ab')2 fragments of the anti-carcinoembryonic antigen (anti-CEA) monoclonal antibody (MoAb) BW 431/31, and 131I meta-iodo-benzylguanidine (MIBG). Additionally, 11 studies were performed with the 111In-labeled MoAb fragment BW 431/31 (seven studies) or the 99mTc-labeled intact anti-CEA MoAb BW 431/26 (four studies). The gold standards for classifying scintigraphic results were biopsy, histology, surgery, and cytology. Six regions were classified as positive or negative in each study: thyroid region, four quadrants (lymph node regions) around the thyroid, and the region of the upper mediastinum. Of 36 sites, 201Tl was true positive (TP) in seven sites, false-positive (FP) in one site, true negative (TN) in 22 sites, and false-negative (FN) in six sites, resulting in a sensitivity of 54% and a specificity of 96%. 131I MIBG was TP in four sites, FP in none of the sites, TN in 23 sites, and FN in nine sites, with a sensitivity of 31% and a specificity of 100%. Immunoscintigraphy (102 sites overall) was TP in 16 sites, FP in five sites, TN in 77 sites, and FN in four sites, resulting in a sensitivity of 80% and a specificity of 94%. Immunoscintigraphy with 111In/99mTc anti-CEA F(ab')2 fragment/intact antibody is superior to scintigraphy with 201Tl and 131I MIBG

    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.

    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.

    Insulin receptor (IR), a member of the receptor tyrosine kinase family, is expressed in normal thyroid cells and affects thyroid cell proliferation and differentiation. The authors measured IR content in benign and malignant thyroid tumors by three independent methods: a specific radioimmunoassay, 125I-insulin binding studies, and immunohistochemistry. The results obtained were compared with the IR content in paired, adjacent, normal thyroid tissue. To assess IR function in thyroid carcinoma cells, glucose uptake responsiveness to insulin was also studied in a human transformed thyroid cell line (B-CPAP) and in follicular carcinoma cells in primary culture. In 9 toxic adenomas, the average IR content was similar to that observed in the 9 paired normal thyroid tissue specimens from the same patients (2.2+/-0.3 vs. 2.1+/-0.3). In 13 benign nonfunctioning, or "cold," adenomas, the average IR content was significantly higher (P thyroid tissue (4.0+/-0.4 vs. 1.6+/-0.2 and 5.6+/-1.0 vs. 1.8+/-0.2, respectively). The finding of a higher IR content in benign "cold" adenomas and in thyroid carcinomas was confirmed by both binding and immunostaining studies. The current studies indicate that 1) IR content is elevated in most follicular and papillary differentiated thyroid carcinomas, and 2) IR content is also elevated in most benign follicular adenomas ("cold" nodules) but not in highly differentiated, hyperfunctioning follicular adenomas ("hot" nodules), which very rarely become malignant. This observation suggests that increased IR expression is not restricted to the thyroid malignant phenotype but is already present in the premalignant "cold" adenomas. It may contribute, therefore, to thyroid tumorigenesis and/or represent an early event that gives a selective growth advantage to transformed thyroid cells.

    The purpose of this study was to investigate the association between chronic lymphocytic thyroiditis (CLT) and malignant tumors of the thyroid. A retrospective review of 647 patients who underwent thyroid surgery at the Department of Breast and Thyroid Surgery in Anhui Provincial Hospital, China in 2012 was performed. The clinicopathological characteristics of patients with thyroid malignancies and CLT were collected. CLT was diagnosed by histopathological method. Among 647 patients, 144 patients had thyroid malignancies and 108 patients had been diagnosed with CLT. Moreover, in total, 44 patients had thyroid malignancies coexistent with CLT: forty-one (93.2%) patients had been diagnosed with the papillary thyroid cancer (PTC); two (4.5%) patients suffered from medullary carcinoma; and one (2.3%) patient suffered from lymphoma. The morbidity of thyroid malignancies in patients with CLT was significantly higher than that in patients without CLT (40.7% versus 18.6%; P CLT compared with those without CLT (P CLT and without CLT. Female predominance was observed in patients with CLT. CLT may have no effect on the progression of thyroid malignant tumor. Nevertheless, the influences of CLT on the prognosis of the thyroid carcinoma still need to be investigated with a larger sample size.

    To distinguish follicular adenoma (FA) and follicular carcinoma (FC) of thyroid in fine needle aspiration cytology (FNAC) is a challenging problem. In this article, we attempted to build an artificial neural network (ANN) model from the cytological and morphometric features of the FNAC smears of thyroid to distinguish FA from FC. The cytological features and morphometric analysis were done on the FNAC smears of histology proven cases of FA (26) and FC (31). The cytological features were analysed semi-quantitatively by two independent observers (RS and PD). These data were used to make an ANN model to differentiate FA versus FC on FNAC material. The performance of this ANN model was assessed by analysing the confusion matrix and receiving operator curve. There were 39 cases in training set, 9 cases each in validation and test sets. In the test group, ANN model successfully distinguished all cases (9/9) of FA and FC. The area under receiver operating curve was 1. The present ANN model is efficient to diagnose follicular adenoma and carcinoma cases on cytology smears without any error. In future, this ANN model will be able to diagnose follicular adenoma and carcinoma cases on thyroid aspirate. This study has immense potential in future. This is an open ended ANN model and more parameters and more cases can be included to make the model much stronger. © 2017 Wiley Periodicals, Inc.

    Hashimoto's thyroiditis emerges in patients who have genetic preponderance such as SNPs of CTLA-4 and risk factors such as excess intake of iodine, pregnancy or postpartum period, and smoking. Such risk factors also affect the entire clinical course. One of the major outcomes in Hashimoto's thyroiditis appears to be increased in cardio-vascular risks through subclinical hypothyroidism and concomitant metabolic syndrome, but in most cases, treatment with L-T4 has little effects on cardio-vascular benefit or quality of life. The pregnant women also have risks for obstetric complications and postpartum thyroid dysfunction. The women who have anti-TPO antibodies, type 1 diabetes, or previous history of post-partum thyroid dysfunction are recommended to be measured their TSH. It is noteworthy that Hashimoto's thyroiditis is sometimes complicated with encephalopathy, papillary carcinoma, or IgG4-related thyroiditis. IgG4-related thyroiditis is partly similar but partly discerned from a variant of Hashimoto's thyroiditis. The pathogenetic roles of this variant on autoimmune-based thyroiditis remain unclear.

    Full Text Available Incidental papillary thyroid carcinomas (IPTCs consist of a significant portion of increasing incidence in papillary thyroid carcinomas. This study investigated the clinicopathological features of IPTCs from different perspectives and by comparing nonincidental PTCs (NIPTCs in patients who underwent total thyroidectomy and lymph node dissection. Basic results were as follows. IPTC was present in 27.9% of 308 patients. IPTCs were significantly accompanied by lymphocytic thyroiditis (LT, particularly, multinodular hyperplasia (MNH. IPTCs were more common in older patients (51.3 years vs. 47.2 years and in female patients. IPTCs significantly differed from NIPTCs in terms of smaller tumour size, lymphatic vessel invasion (2.6% vs. 97.4%, extrathyroidal extension (4.3% vs. 95.7%, lymph node metastasis (3.6% vs. 96.4%, multifocality (21.2% vs. 78.8%, bilaterality (5.3% vs. 94.7%, and BRAFV600 mutation (6.7% vs. 93.3%. Older age, bilaterality, encapsulation, and radioactive iodine (RAI were significantly more common in IPTCs > 5 mm than in those ≤ 5 mm. In conclusion, IPTCs are more commonly associated with LT and MNH. IPTCs may have a more favourable prognosis than NIPTCs, and tumour size > 5 mm may predict bilaterality and need for RAI. Nevertheless, the patient-based clinical approach in IPTCs may have benefits in the management of IPTCs.

    Objective: To study the status of telomerase activity during the development of thyroid tumors, and to determine whether telomerase activity can be used clinically as a molecular marker in the differential diagnosis of thyroid cancer. Methods: Telomerase activity was measured in 37 thyroid carcinomas, 33 benign thyroid lesions and 30 normal thyroid tissue samples by means of a modified TRAP-PCR. The assay was also applied to 15 fine needle aspirates (FNAs) of thyroid carcinomas to test its sensitivity. Results: Thirty-one of 37 thyroid carcinomas (83.8%), 7 of 33 benign thyroid lesions (21.2%), and 4 of 30 adjacent normal thyroid tissue samples expressed telomerase activity, 15 FNAs also had positive telomerase activity, just as their corresponding tissue specimens. The quantitative analysis showed that the telomerase activity was significantly higher in thyroid carcinomas than that in benign thyroid tissue samples. And medullary carcinomas and anaplastic carcinomas had higher levels of telomerase activity than papillary carcinomas. Conclusions: Telomerase activity is a good marker for thyroid carcinomas. The quantitative TRAP-PCR might have more potential application in the differential diagnosis of tumors and the estimation of tumor progression and prognosis. And this sensitive assay could become a useful new modality for supplementing microscopic cytopathology in the detection of cancer cells in small tissue samples and FNAs

    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.

    To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

    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)

    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.

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

    In a patient with a differentiated thyroid cancer the standard treatment protocol to be followed is surgery, ablation of thyroid remnants with 131 Iodine ( 131 I), and TSH suppression. However, the treatment with 131 I is not effective in some cases, and it no longer becomes a therapeutic option due to cell de-differentiation with loss of 131 I uptake. Systemic treatment can be used as other options, although patients are not always responsive; thus, the disease may progress and therapeutic options may run out. Endocrine tumours may express somatostatin receptors,and this characteristic has been used, not only for diagnosis, but also for their treatment through somatostatin analogue labelling with radioactive isotopes. This was the case of a patient suffering from iodine-refractory follicular thyroid carcinoma, with somatostatin receptors expression, treated with 177 Lu-DOTATATE, showing an excellent clinical and analytical response.

    2013-01-01

    Full Text Available Introduction. Follicular thyroid carcinoma (FTC frequently metastasizes to the lungs and bones. However, metastasis to the skeletal muscles is an extremely rare manifestation of FTC. To date, only seven cases of FTC have been reported in the literature. Skeletal muscle metastases from FTC usually remain asymptomatic or manifest as swelling and are associated with dismal prognosis. Case Presentation. A 45-year-old Saudi woman presented with right buttock swelling since 8 months. Physical examination revealed right gluteal mass of size  cm and right thyroid lobe nodule. The rest of examination was unremarkable. Magnetic resonance imaging (MRI showed  cm lobulated mass arising from the gluteus medius muscle, and tru-cut biopsy confirmed the metastatic papillary carcinoma of thyroid origin. The patient subsequently underwent palliative radiotherapy followed by total thyroidectomy and radioactive iodine ablation. At the time of publication, the patient was alive with partial response in gluteal mass. Conclusion. Skeletal muscles metastases are a rare manifestation of FTC, and searching for the primary focus in a patient with skeletal muscle metastasis, thyroid cancer should be considered as differential diagnosis.

    2011-01-01

    Full Text Available Thyroid hormone, operating through its receptors, plays crucial roles in the control of normal human physiology and development; deviations from the norm can give rise to disease. Clinical endocrinologists often must confront and correct the consequences of inappropriately high or low thyroid hormone synthesis. Although more rare, disruptions in thyroid hormone endocrinology due to aberrations in the receptor also have severe medical consequences. This review will focus on the afflictions that are caused by, or are closely associated with, mutated thyroid hormone receptors. These include Resistance to Thyroid Hormone Syndrome, erythroleukemia, hepatocellular carcinoma, renal clear cell carcinoma, and thyroid cancer. We will describe current views on the molecular bases of these diseases, and what distinguishes the neoplastic from the non-neoplastic. We will also touch on studies that implicate alterations in receptor expression, and thyroid hormone levels, in certain oncogenic processes.

    Anaplastic thyroid carcinoma (ATC) is a highly aggressive tumor with a median survival rate of 6 months. To analyze presentation, treatment, morphology, immunohistochemistry, and nuclear DNA analysis of a cohort of patients with ATC. Twelve patients with ATC (11 female) with a mean age of 65 years were seen at our hospital from 1970-1995. The data were obtained from the clinical records and the morphology, immunohistochemic studies and DNA pattern were performed in slides obtained from archival specimens. Previous or coexisting thyroide disease was documented in 10 patients (9 multinodular goiters and one Grave's). The most frequent presentation was a rapidly growing tumor associated with dysphagia, cervical pain, hoarseness and dyspnea. A cold thyroid nodule was detected by thyroid scan in 10 patients. The most frequent subtype was the spindle cell variety. Papillary thyroid carcinoma coexisted in eight cases, two of them corresponded to the tall cell variant. Reactivity for S-100 protein and vimentin was studied in six patients: all were positive for S-100 protein and vimentin, 5/6 for epithelial membrane antigen, half for carcinoembriogenic antigen, 2/6 for thyroglobulin and calcitonin, and one for neuronal specific enolase. These six tumors showed a diploid DNA pattern. Tumor resection was achieved in 2/11 and none survived six years after diagnosis. ATC is a highly aggressive tumor coexisting with thyroid pathologies. Spindle cell variant is the most frequent with positive reactivity for S-100 protein, vimentin and epithelial membrane antigen. Most tumors have a diploid DNA content.

    A reevaluation of the clinical value of radioimmunological thyroglobulin (hTg) determination during follow-up of differentiated thyroid carcinoma, in general, confirms our previous results already published in 1980 and 1981. A total of 163 patients with differentiated thyroid carcinoma, 53 with papillary and 110 with follicular carcinoma, was studied up to January 1984. 586 sera are included in this study. The differentiation of suspicious from nonsuspicious findings was found to be based upon a cut-off concentration of 10 μg/l. Pathological findings were associated with hTg concentrations above 20 μg/l. Diagnostic accuracy was calculated to be between 95 and 97%, sensitivity of the method in comparison to be radioiodine whole-body scan was 98 versus 83%, respectively, and specificity 94%. At first 5 false negative and 6 false positive hTg findings have been obtained. 7.6% of the patients demonstrated endogeneous hTg antibodies by Boyden test. 7.7% of Boyden test negative sera showed an unacceptable hTg recovery of worse than +- 50%, which was possibly due to endogeneous antibodies. Again, endogenous TSH was able to stimulate hTg secretion in the form of elevated levels, yet did not affect the clinical diagnosis. Examples of the behaviour of hTg levels during follow-up are demonstrated. Specifically, the cases with false hTg findings are discussed. Basically, the conclusions are the same as in 1980 and 1981: hTg determination is able to replace the routinely performed radioiodine whole-body scan during follow-up, if once residual thyroid tissue and metastases have been excluded by means of radioiodine and an optimal follow-up program is used.

    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

    DNA content has been reported to be of prognostic significance in differentiated thyroid carcinoma. Since malignant tumors with irradiation as an initiator often contain DNA aberrations, the DNA content of well-differentiated thyroid carcinoma in patients with a prior history of low-dose head and neck irradiation was determined and compared with similar nonradiation-associated lesions. The DNA content of thyroid cancers from 53 patients was determined with use of flow cytometry. Sixteen radiation-associated thyroid carcinomas (11 papillary, 3 follicular, and 2 medullary) all were diploid. In a group of 37 nonradiation-associated tumors, 10 were aneuploid (10 of 29 papillary carcinomas and 0 of 2 follicular or 6 medullary carcinomas). This difference in DNA content is significant (p less than 0.02, Fisher's exact test). These findings were unexpected and suggest that if the initiating irradiation causes a DNA aberration, this aberration is not reflected in DNA content as measured by means of flow cytometry

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

    Papillary thyroid carcinoma (PTC) is the most common type among thyroid cancers. The diagnosis of PTC may be challenging when follicular variant (FVPTC) of this disease is present due to the resemblance of nuclear properties of the classical type (CVPTC). However, making use of ancillary molecular markers in the diagnosis of PTC may help. In our study, we aimed to evaluate the SEPT7 protein expression in PTC. A total of 55 paraffin block tissue samples comprising encapsulated FVPTC (FVPTC(e), n=25), and CVPTC (n=15), and benign hyperfunctioning thyroid nodules (HypN, n=15) were used in this study. Nuclear, cytoplasmic, and overall (total) SEPT7 protein expression levels were determined by using immunohistochemistry. Nuclear, cytoplasmic, and overall SEPT7 expressions (p=0.02, p=0.001, p=0.002, respectively) were significantly lower in FVPTC(e) tissues when compared to HypN. In CVPTC group, nuclear expression was significantly lower (p=0.004) while overall and cytoplasmic expressions were not changed (p>0.05). In HypN group, highest nuclear (mean=2.73), cytoplasmic (mean=2.86), and overall (mean=2.86) expression scores were detected. Significantly lower SEPT7 expression in all expressional categories in FVPTC(e) group may be a sign of different molecular signature in this type of tissue. Copyright © 2014 Elsevier GmbH.

    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

    Thyroid cancer has a multifactorial aetiology resulting from the interaction of genetic and environmental factors. Several low penetrance susceptibility genes have been identified but their effects often vary between different populations. Somatic point mutations and translocations of the REarranged during Transfection (RET) proto-oncogene are frequently found in thyroid cancer. The aim of this case-control study was to determine the effect of four well known RET single nucleotide polymorphisms (SNPs) on the risk for differentiated thyroid carcinoma. A total of 545 Portuguese patients and 543 controls were genotyped by PCR and restriction enzyme analysis, for the following SNPs: G691S (exon 11, rs1799939 G/A), L769L (exon 13, rs1800861 T/G), S836S (exon 14, rs1800862 C/T), and S904S (exon 15, rs1800863 C/G). The minor allele of S836S was overrepresented in patients with papillary thyroid carcinoma (PTC) when compared to controls (OR 1.57; 95% CI 1.05–2.35; p = 0.026). The GGTC haplotype was also overrepresented in PTC (OR 2.51; 95% CI 1.07–5.91; p = 0.029). No associations were found in follicular thyroid carcinoma (FTC). Multivariate logistic regression analysis showed no differences regarding gender, age at diagnosis, lymph node or distant metastasis. However, a near significant overrepresentation of the minor alleles of G691S and S904S was found in patients with tumours greater than 10 mm of diameter at diagnosis. These data suggest that the RET S836S polymorphism in exon 14 and the GGTC haplotype are risk factors for PTC, but not FTC, and that the G691S/S904S polymorphisms might be associated with tumour behaviour.

    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)

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

    Of 1203 patients who received radiation treatment for acne vulgaris between 1940 and 1968, 302 were recalled and examined, 121 at Geisinger Medical Center and the remainder by their local physicians. Radiation records were reviewed on all patients. Lead-rubber and cones had been used as shielding. Mean age at the time of exposure was 21 years and mean total exposure was 692 R. Palpable nodular thyroid disease was found in eight patients (2.6%). Of these, thyroid carcinoma was detected in two patients (0.66%). Although the number of patients examined was small, the incidence of carcinomas was unexpectedly high. The authors conclude that follow-up examination is worthwhile for patients previously treated by irradiation for acne vulgaris

    Autonomously functioning thyroid nodules (AFTNs) in children and adolescents (under age 18) are unusual but are not as rare as earlier reports suggested. These lesions have a significantly different biologic potential than similar lesions in older patients. In the younger age group there is a more rapid progression toward toxicity and a higher incidence of thyroid carcinoma. Our experience with 12 patients is combined with those previously reported for identification of a total of 61 children and adolescents with AFTNs, of whom 53 have undergone operation. Hyperthyroidism was present in 15 patients (24.6%), and in six patients (11.3%) the AFTN was due to a well-differentiated thyroid carcinoma. Surgical treatment is advisable for all children and adolescents with AFTNs because of the risks of hyperthyroidism and thyroid carcinoma. Surgical excision (lobectomy is preferred) results in rapid restoration of a euthyroid state for the toxic AFTN and allows histopathologic diagnosis. Therapy with radioiodine is not advisable for treatment of AFTNs in this age group. Thyroid-stimulating hormone suppression should be used for all patients with a diagnosis of thyroid carcinoma

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

    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.)

    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
