Abstract
Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor. However, non-elevated calcitonin levels have been reported in the literature. We present the case of an 81-year-old woman with chronic elevations in carcinoembryonic antigen (CEA) levels for the past 15 years, despite normal calcitonin levels, who was ultimately diagnosed with MTC. The patient had a remote history of breast cancer and presented with symptoms of unintentional weight loss, fatigue, and joint pain. A positron emission tomography (PET) scan revealed low fluorodeoxyglucose (FDG) uptake in partially calcified thyroid nodules, and fine needle aspiration cytology was consistent with medullary carcinoma. The patient underwent total thyroidectomy, with pathology revealing a pT1aN0M0 medullary thyroid microcarcinoma with negative margins. After thyroidectomy, CEA levels decreased to within the normal range, and calcitonin levels remained normal. This case highlights the importance of considering MTC in patients with unexplained chronic elevations in CEA levels, even with normal calcitonin levels.

Abstract
BACKGROUND Medullary thyroid cancer (MTC) is a rare neuroendocrine tumor originating from parafollicular C-cells. It represents 2% of all thyroid malignancies and 0.4-1.4% of all thyroid nodules. MTC has a variable clinical course, with complete remission often difficult to achieve. An early diagnosis is still crucial in MTC management, enabling a radical surgical treatment, the only chance for curing the patient. Calcitonin (Ct) is a very sensitive MTC tumor marker in patients with thyroid nodules, although Ct-negative MTCs have been described, but not all clinical guidelines recommend the Ct routine measurement in thyroid nodules because of the absolute low prevalence of MTC in the general population and the consequent scarce positive predictive value of Ct. Moreover, the specificity of moderately high Ct levels is not high. Thus, the scientific community has been investigating the possible role of other tumor markers for MTC diagnosis and prognosis. AIM OF THE REVIEW The present review is an attempt to summarize the knowledge available today on the role of other serum markers for MTC alternative to Ct. CONCLUSIONS At present, literature data does not seem solid enough yet to establish effective flowcharts in evaluating a thyroid nodule for MTC, involving alternative serum markers, particularly in cases of moderately high CT levels. MTC is a rare diagnosis in thyroid nodules, and this makes the evaluation of any tumor serum marker accuracy problematic. More extensive and prospective studies are needed to shed more light on this intriguing challenge.

Abstract
OBJECTIVES This study reviewed the institutional experience of performing calcitonin immunostain on an additional ThinPrep slide in fine-needle aspiration (FNA) diagnosis of medullary thyroid carcinoma (MTC). METHODS Thyroid FNA cases with MTC suspected or included in the differential diagnosis during cytologic evaluation and calcitonin immunostain performed were retrieved and reviewed. RESULTS Calcitonin immunostain was performed in 132 cases with 41 positive, 81 negative, and 10 indeterminate results. All calcitonin-positive cases had a cytologic diagnosis of MTC while all calcitonin-negative cases were cytologically classified as non-MTCs except for two cases suspicious for MTC. In 10 cases with an indeterminate calcitonin result, diagnoses of non-MTC and suspicious for MTC were rendered in 6 and 4 cases, respectively. Histopathologic follow-up was available in 85 (64%) cases. All cytologically diagnosed MTC cases were confirmed on histopathology. In 3 MTC cases with an indeterminate calcitonin result, 1 case was misclassified cytologically as follicular neoplasm. The calculated sensitivity, specificity, positive predictive value, and negative predictive value of calcitonin immunostain were all 100% for diagnosing MTC. CONCLUSIONS Our study demonstrates the feasibility of performing calcitonin immunostain on an additional ThinPrep slide. Calcitonin immunocytochemistry is a valuable adjunct test for FNA diagnosis and differential diagnosis of MTC.

Abstract
BACKGROUND Few studies have categorized ultrasound (US) findings of various sized medullary thyroid carcinomas (MTCs) according to updated guidelines. PURPOSE To evaluate and compare the differences in US findings of MTC according to nodule size, using the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) and American Thyroid Association (ATA) guidelines. MATERIAL AND METHODS The study included 119 patients with 129 MTC nodules, which were surgically confirmed at our institution between March 1999 and September 2017. Nodules were divided into large (≥1.0 cm) and small (<1.0 cm) groups. US images were analyzed according to the K-TIRADS and ATA guidelines. The differences in US characteristics between small and large nodules were compared using Fisher's exact or Chi-square tests. RESULTS Of 129 MTC nodules, 84 (65.1%) were large nodules and 45 (34.9%) were small nodules. According to the nodule size, small MTC nodules were classified more commonly as high suspicion by K-TIRADS and ATA (95.6% and 93.3%, respectively) (P < 0.001), but presented neither cystic change, isoechogenicity, nor low suspicion category by K-TIRADS and ATA. In contrast, large MTC nodules showed more frequently cystic change (15.5%), isoechogenicity (16.7%), smooth margins (50%), or low or intermediate suspicion US features by K-TIRADS and ATA (59.6% and 36.0%, respectively) (all P values < 0.001). CONCLUSION Most small MTC nodules are classified as high suspicion on US, whereas large MTC nodules are diagnosed more frequently as low or intermediate suspicion by K-TIRADS and ATA.

Abstract
Calcitonin-negative neuroendocrine tumor (CNNET) of the thyroid is an extremely rare entity. In some of the previously reported cases within the literature, the terms “atypical medullary thyroid carcinoma,” “calcitonin-free oat cell carcinoma,” and “a distinct clinical entity” were applied to NETs without definitive evidence of calcitonin production. In the English-language literature, not only are there only few reported cases of CNNET, but the criteria for diagnosis in these cases are also controversial. Most of the current published cases were also treated surgically for local disease. We describe a case of NET of the thyroid with calcitonin, chromogranin A and thyroglobulin negativity, synaptophysin and TTF-1 positivity, and a high Ki-67 proliferation index with metastases in the cervical region as well as mediastinal adenopathies. This case was considered an unresectable thyroid carcinoma, and chemotherapy including cisplatin and etoposide was started as neoadjuvant treatment at the department of medical oncology. Total thyroidectomy plus bilateral and central cervical dissection was performed, and the patient underwent 2 cycles of adjuvant radiotherapy. Currently, the patient's <sup>18</sup>F-FDG-PET/CT findings show a complete response 17 months after diagnosis. In conclusion, CNNET of the thyroid is very rare and there is limited evidence regarding treatment in patients with metastases. Chemotherapy including cisplatin and etoposide as well as early aggressive surgical resection appears to positively impact patients' survival.

Abstract
Background Medullary thyroid carcinoma (MTC) is a relatively rare malignant tumor subtype originated the parafollicular C cells of the thyroid gland, producing tumor markers including calcitonin (Ctn), carcinoembryonic antigen (CEA), and chromogranin A. Preoperative serum Ctn and CEA value is important for assessing disease burden, postoperative serum Ctn and CEA can help to determine whether there are recurrence and distant metastasis. Case Presentation We report a rare case in which the CEA level continued to increase and the Ctn value was normal after total thyroidectomy and central lymph node dissection in a MTC patient. The patient was asymptomatic during one and half year follow-up until lateral lymph node metastasis was revealed. However, the CEA level raised again after lateral neck lymph node dissection and bone metastases were found by 18F-FDG PET-CT. Conclusion This case reminded us the recurrence of MTC should be suspected for patients with simply elevated CEA after surgery for MTC. Differential diagnosis of other malignant tumors and timely lymph node biopsy is of great significance for management.

Abstract
BACKGROUND Thyroid nodules are very common in general medical practice, but rarely turn out to be a medullary thyroid carcinoma (MTC). Calcitonin is a sensitive tumour marker for the detection of MTC (basal calcitonin). Sometimes a stimulation test is used to improve specificity (stimulated calcitonin). Although the European Thyroid Association's guideline advocates calcitonin determination in people with thyroid nodules, the role of routine calcitonin testing in individuals with thyroid nodules is still questionable. OBJECTIVES The objective of this review was to determine the diagnostic accuracy of basal and/or stimulated calcitonin as a triage or add-on test for detection of MTC in people with thyroid nodules. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and Web of Science from inception to June 2018. SELECTION CRITERIA We included all retrospective and prospective cohort studies in which all participants with thyroid nodules had undergone determination of basal calcitonin levels (and stimulated calcitonin, if performed). DATA COLLECTION AND ANALYSIS Two review authors independently scanned all retrieved records. We extracted data using a standard data extraction form. We assessed risk of bias and applicability using the QUADAS-2 tool. Using the hierarchical summary receiver operating characteristic (HSROC) model, we estimated summary curves across different thresholds and also obtained summary estimates of sensitivity and specificity at a common threshold when possible. MAIN RESULTS In 16 studies, we identified 72,368 participants with nodular thyroid disease in whom routinely calcitonin testing was performed. All included studies performed the calcitonin test as a triage test. Median prevalence of MTC was 0.32%. Sensitivity in these studies ranged between 83% and 100% and specificity ranged between 94% and 100%. An important limitation in 15 of the 16 studies (94%) was the absence of adequate reference standards and follow-up in calcitonin-negative participants. This resulted in a high risk of bias with regard to flow and timing in the methodological quality assessment. At the median specificity of 96.6% from the included studies, the estimated sensitivity (95% confidence interval (CI)) from the summary curve was 99.7% ( 68.8% to 100%). For the median prevalence of MTC of 0.23%, the positive predictive value (PPV) for basal calcitonin testing at a threshold of 10 pg/mL was 7.7% (4.9% to 12.1%). Summary estimates of sensitivity and specificity for the threshold of 10 pg/mL of basal calcitonin testing was 100% (95% CI 99.7 to 100) and 97.2% (95% CI 95.9 to 98.6), respectively. For combined basal and stimulated calcitonin testing, sensitivity ranged between 82% and 100% with specificity between 99% and 100%. The median specificity was 99.8% with an estimated sensitivity of 98.8% (95% CI 65.8 to 100) . AUTHORS' CONCLUSIONS Both basal and combined basal and stimulated calcitonin testing have a high sensitivity and specificity. However, this may be an overestimation due to high risk of bias in the use and choice of reference standard The value of routine testing in patients with thyroid nodules remains questionable, due to the low prevalence, which results in a low PPV of basal calcitonin testing. Whether routine calcitonin testing improves prognosis in MTC patients remains unclear.

Abstract
BACKGROUND Neuroendocrine tumors mainly occur in the stomach, intestine, pancreas, and lung and are rarely detected in the thyroid. Thyroid neuroendocrine tumors, designated medullary thyroid carcinoma, generally present with elevated calcitonin. Calcitonin-negative neuroendocrine tumors of the thyroid are extremely rare.
CASE SUMMARY Here, we present a case report of a 56-year-old female patient with a neck pain complaint. Total thyroidectomy was conducted after comprehensive evaluation, and diagnosis was confirmed as calcitonin-negative neuroendocrine tumor of the thyroid. Two months later, liver metastasis was detected, and transcatheter arterial chemoembolization was subsequently performed to control growth. However, the curative effect was unsatisfactory and multiple intrahepatic metastases occurred after 3 mo.
CONCLUSION Owing to the rarity of this disease, no clear guidelines are available for treatment. In addition to reporting this rare case, we have reviewed and summarized associated medical literature with an aim to provide a comprehensive reference platform for subsequent research.

Abstract
BACKGROUND Medullary thyroid carcinoma is a malignant uncommon and aggressive tumour of the parafollicular C cells. In about 75% of cases it is sporadic while, in case of RET mutation, it is associated to multiple endocrine neoplasia type 2 (25% of cases). The biochemical features of medullary thyroid carcinoma include the production of calcitonin and carcinoembryogenic antigen. The above-mentioned features are useful in the diagnostic process as well as in the follow up and in the prognostication of the disease. Even if calcitonin elevation is strongly associated to MTC, it can also be found increased in many pathological different conditions as pregnancy, lactation, C-cells hyperplasia, autoimmune thyroiditis, end stage renal disease, lung and prostate cancer and several neuroendocrine tumours. Major medullary thyroid tumours are usually connected to high doses of circulating calcitonin, in fact non-secretory variants have hardly been described. CASE PRESENTATION We herein report the case of a 59 years old male, who had undergone total thyroidectomy for multinodular goiter with negative preoperative calcitonin, showing medullary thyroid carcinoma at definitive pathology. To the best of our knowledge, this is the first case documenting a non-secretory medullary thyroid carcinoma, with double negative markers at the time of diagnosis and at the relapse. CONCLUSION A Literature review underlining pathological hypothesis, differential diagnosis and alternative and innovative biomarkers to identify non-secretory medullary thyroid carcinoma was carried out.

Abstract
BACKGROUND Medullary thyroid cancer (MTC) accounts for 5% of all thyroid cancers and occurs either sporadically or in a hereditary pattern. Routine calcitonin (CT) measurement is suggested for MTC screening in patients with nodular thyroid disease. PATIENT FINDINGS A 45 years-old woman incidentally discovered, with neck ultrasound, the presence of thyroid micronodules. Fine-needle aspiration (FNA) on thyroid prevailing nodule did not demonstrate cellular atypia. During follow-up, FNA was repeated on the previously analyzed nodule suspicious for Hürthle cell nodule suspicious for follicular neoplasm and on another hypoechoic right nodule which showed cellular atypia. CT was <2 pg/ml (normal values <18.2 pg/ml), anti-thyroid antibodies were positive and the patient showed a normal thyroid function. The patient also was diagnosed with primary hyperparathyroidism with an enlarged parathyroid gland behind the right thyroid lobe. Therefore, she underwent total thyroidectomy and a selective parathyroidectomy was performed. Histology showed an encapsulated microMTC (pT1aNxMx) associated with diffuse C-cell hyperplasia and lymphocytic thyroiditis. The neoplasm was positive for calcitonin and chromogranin A and negative for thyroglobulin. A right parathyroid adenoma was also diagnosed. One month after surgery basal and stimulated CT were <2 ng/ml. Genetic analysis did not reveal mutation of RET proto-oncogene. Twelve months after surgery, neck ultrasonography, chest and abdomen computed tomography did not demonstrated residual/recurrent disease with undetectable serum CT. CONCLUSION In the literature, few MTC cases with normal serum CT have been reported. Although MTC without elevated plasma CT is extremely rare, normal or low CT levels, do not entirely exclude this diagnosis.

Calcitonin negative Medullary Thyroid Carcinoma: a challenging diagnosis or a medical dilemma? BMC Endocr Disord 2019; 19:45. [PMID: 31142313 PMCID: PMC6541563 DOI: 10.1186/s12902-019-0367-2] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 04/08/2019] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Medullary thyroid carcinoma is a neuroendocrine tumor belonging form a malignant growth of the thyroid parafollicular C-cells, representing from 1 to 10% of all thyroid cancer. The biochemical activity of medullary thyroid carcinoma includes the production of calcitonin and carcinoembryogenic antigen, which are sensitive tumor markers, facilitating the diagnosis, follow-up and prognostication. The diagnosis is reached through the identification of high basal calcitonin serum level or after pentagastrin stimulation test. Medullary thyroid carcinoma is able to produce other relevant biomarkers as procalcitonin, carcinoembryionic antigen and chromogranin A. In Literature are described few cases of medullary thyroid carcinoma without elevation of serum calcitonin, an extremely rare event. The aim of this study was to analyse the presentation, the main features and therapeutic management of medullary thyroid carcinoma associated with negative serum calcitonin levels. METHODS Using the PubMed database, a systematic review of the current Literature was carried out, up to February 2018. Finally, nineteen articles met our inclusion criteria and were selected according to the modified Newcastle-Ottawa scale. RESULTS Fourty-nine patients with definitive pathology confirming medullary thyroid carcinoma and with calcitonin serum level in the normal range were identified (24 female, 24 male and not reported gender in 1 case). Mean age was 51.7 years. Serum calcitonin levels were reported for 20 patients with a mean value of 8.66 pg/mL and a range of 0.8-38 pg/mL. Despite the low or undetectable calcitonin serum level, at immunochemistry in almost the half of the cases reported by the Authors, the tumors presented diffuse or focal positivity for calcitonin and carcinoembryionic antigen, while was reported a chromogranin A positivity in 41 of the 43 tested patients. CONCLUSIONS Calcitonin negative medullary thyroid carcinoma is an extremely rare pathology. The diagnosis and the surveillance is often challenging and delayed, due to the lack of elevation of serum markers as calcitonin and carcinoembryionic antigen. Further studies are needed, to better define options for management of non secretory medullary thyroid carcinoma and to identify new and reliable biomarkers associated to diagnosis and relapse of this medical dilemma.

Abstract
Medullary thyroid carcinoma (MTC) is a malignant tumor of the parafollicular cells, which produce calcitonin. As a result, calcitonin is an important tool for diagnosing MTC. When there is focal or no calcitonin staining, diagnosis of MTC can be challenging as this may suggest differences in cell origin and in prognosis and recurrence of the disease. The prognosis and guidelines for management and follow up for MTC remain inconclusive. Here, we present a case of primary neuroendocrine tumor of the thyroid gland with only focal calcitonin staining on immunohistochemistry and low serum calcitonin level despite a tumor size of almost 4 cm. The assumption of C-cell origin was made from positive staining for carcinoembryonic agent (CEA), thyroid transcription factor 1 (TTF-1) and paired box 8 (PAX8) without expression of thyroglobulin (Tg). The patient underwent thyroid lobectomy and follow-up monitoring with ultrasound and measurements of calcitonin and CEA levels, without any further surgical intervention. Few cases of neuroendocrine tumors with limited calcitonin expression have been published and the etiology and prognosis are still unknown. Our case suggests that limited calcitonin expression cannot completely exclude the diagnosis of MTC. This rare type of MTC should be differentiated from the typical presentation of MTC. Treatment and post-operative surveillance should be tailored based on the individual.

Abstract
Purpose For the differential diagnosis of medullary thyroid carcinoma (MTC) on thyroid nodules, ultrasound-guided fine-needle aspiration cytology is a useful and safe procedure, but its diagnostic accuracy is not high enough. As an ancillary method to accurately diagnose MTC, the calcitonin in fine-needle aspirate washout fluid (FNA-Ct) is used. However, no data are available about cut-off values of FNA-Ct using the currently available electrochemiluminescence immunoassay (ECLIA). Methods We investigated 180 thyroid nodules in 141 patients. After smearing, the syringe and needle used for the FNA were rinsed with normal saline (0.5 mL). The calcitonin in the washout was measured by ECLIA. Results The FNA-Ct in the non-MTC nodules of MTC patients, non-MTC nodules of non-MTC patients, and MTC nodules were 10.6-2100 pg/mL (median 24.6 pg/mL), < 0.5-21.0 pg/mL (median < 0.5 pg/mL), and 94.9-4,070,000 pg/mL (median 177,000 pg/mL), respectively. A receiver operating characteristic analysis of the MTC nodules and the non-MTC nodules of the non-MTC patients indicated that the cut-off value was 21.0 pg/mL, leading to 100% sensitivity and 100% specificity. Conclusions This is the first study to determine the cut-off value of FNA-Ct with an ECLIA, and we propose that the optimal cut-off value is 21.0 pg/mL.

Abstract
The biochemical activity of medullary thyroid carcinoma (MTC) includes production of calcitonin (CT), chromogranin A (CgA) and carcinoembryonic antigen (CEA). Routine CT measurement has been proposed as part of the initial evaluation of thyroid nodules and its use could ultimately decrease the morbidity and mortality of MTC. We report on a 43-year-old female patient with a large MTC expressing CT, CgA and CEA on immunostains but with negative preoperative CT and CgA results. Serum CEA was slightly increased and its rapid disappearance predicted radical cure by surgery as confirmed by 2-year follow-up. Our report illustrates that a diagnosis of MTC cannot always be excluded by negative preoperative CT. Fine-needle aspiration with cytomorphological analysis and complementary immunocytochemistry remains an essential diagnostic tool. Finally, serum aliquots must be stored before thyroid surgery in order to measure circulating forms of complementary markers found by tissue immunostaining (CEA and CgA)

Abstract
PURPOSE Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. METHODS We conducted the calcium stimulation test using ECLIA in 21 men with non-medullary thyroid carcinoma (non-MTC), before and after total thyroidectomy. RESULTS Preoperatively, the basal calcitonin values were within normal limits in all patients. They increased to a mean value of 37.6 pg/mL after calcium stimulation, and we calculated that the reference upper limit was 83.7 pg/mL. The stimulation test results after total thyroidectomy showed undetectable basal and stimulated calcitonin values in every patient (<0.5 pg/mL). CONCLUSIONS To our knowledge, this is the first study to calculate reference values for this stimulation test using an ECLIA in men with non-MTC. We propose that men can be regarded as biochemically cured or as having normal serum calcitonin values when the stimulated calcitonin values obtained by ECLIA are <83.7 pg/mL before and <0.5 pg/mL after total thyroidectomy.

Abstract
BACKGROUND Medullary thyroid carcinoma (MTC), defined as a malignant tumour with C-cell differentiation, is of neuroendocrine origin and is characterized by the synthesis and secretion of calcitonin (CT). MTC without CT secretion has been reported on rare occasions. The purpose of this study was to evaluate the histological, immunohistochemical, and molecular pathologic features as well as the clinical significance of non-secretory MTC (NCR-MTC). METHODS A retrospective analysis of patients with NCR-MTC was performed. The clinical features of NCR-MTC, including age, gender, tumour size and number, clinical signs of hypocalcaemia and diarrhoea, and the presence of lymph node metastasis, as well as the pathologic features of the disease, including tumour morphology, presence of neuroendocrine structures, capsular invasion, and immunohistochemical expression and presence of mutations in the RET gene, were evaluated. RESULTS Nineteen patients with NCR-MTC were identified among 158 patients with MTC, resulting in a prevalence rate of 12.02%. Patients with NCR-MTC typically had masses less than 1cm in size (73.7%, 14/19). Hypocalcaemia was not present in 94.7% (18/19) of patients. While 42.1% (8/19) of patients with NCR-MTC did not have amyloid deposits, only 18% (25/139) of patients with secretory MTC did not have such deposits. While 95.7% (133/139) of the control group of patients with secretory MTC had neuroendocrine tumour structure, only 84.2% (16/19) of the patients with NCR-MTC had this type of tumour structure. Patients with NCR-MTC were also less likely to have vascular tumour thrombus, lymph node metastasis or thyroid capsular invasion. With regard to immunohistochemistry, CT expression was mostly negative, and carcinoembryonic antigen (CEA) expression was positive in 21.1% (4/19) of patients with NCR-MTC, while only 5.8% (8/139) of patients in the control group had positive CEA expression. CONCLUSIONS The prevalence of NCR-MTC was low (12.02%). This type of tumour was smaller in size and more differentiated. Compared with the control group, relatively few patients had obvious symptoms, hypocalcaemia, lymph node metastasis, thyroid capsular or vascular invasion, or tumours with amyloid or neuroendocrine tumour structure.

Abstract
Calcitonin is a very sensitive tumor marker of medullary thyroid carcinoma (MTC). MTC patients usually have very high values of serum calcitonin that can be used to diagnose the disease. To improve the diagnostic sensitivity in family members with small MTCs and to evaluate the postoperative biochemical cure status, a calcium stimulation test is widely used. Serum calcitonin has been measured using several methods, but in Japan, only an electrochemiluminescence immunoassay (ECLIA) is currently performed to determine serum calcitonin. Reference values for the calcium stimulation test using an ECLIA have not been reported. Here we conducted a calcium stimulation tests in 26 patients without MTC before and after total thyroidectomy. Preoperatively, the basal calcitonin values of all patients were within normal limits and increased to a mean of 14.4 pg/mL after calcium stimulation. We transformed the peak values before total thyroidectomy to a logarithmic distribution and calculated the normalized mean ± 1.96× standard deviation; the reference upper limit was thus expressed. In the female patients with non-MTC, the reference upper limit was 67.6 pg/mL. In all patients, the calcium stimulation test results after total thyroidectomy showed undetectable basal and stimulated calcitonin values (<0.5 pg/mL). This is the first study to determine reference values to be used for the calcium stimulation test along with an ECLIA in non-MTC patients. We propose that female patients are regarded as biochemically cured or normal when the stimulated calcitonin values by ECLIA are <67.6 pg/mL before surgery and <0.5 pg/mL after total thyroidectomy.

Abstract
PURPOSE Medullary thyroid carcinoma (MTC) is a relatively uncommon malignant tumor of the parafollicular C cells of the thyroid, which distinguishing feature is the production of calcitonin (CT). CT is a well-recognized tool in the diagnosis and the postsurgical follow-up of patients with MTC with a high sensitivity and specificity, and represents a powerful prognostic indicator. Usually, there is a direct correlation between tumor size and basal CT levels. However, few cases of CT-negative MTCs have been reported in literature and criteria for diagnosis and follow-up are still controversial. METHODS We performed a brief review on CT-negative MTC and reported our experience on this rare condition, focusing on the clinical characteristics at presentation, the histological and immunostaining features, and the management. RESULTS Fifteen cases of large, palpable, CT-negative MTCs have been reported in the literature so far; moreover, we reported four cases followed at our center. CONCLUSIONS Although CT-negative MTC is rare, normal/low serum levels of CT and CEA cannot completely exclude the possibility of the diagnosis, when suspected. It is well accepted that early diagnosis is crucial, but there is still no consensus on the optimal postoperative surveillance strategy. The ultrasound evaluation of the cervical region, together with abdominal computerized tomography scan, chest X-ray, and fluorine18-fluorodeoxyglucose ((18)F-FDG) PET/computed tomography (FDG-PET/CT), would be recommended in the follow-up of such cases.

Aproximadamente 25% dos casos de CMT são hereditários e decorrentes de mutações ativadoras no proto-oncogene RET (REarranged during Transfection). O CMT é uma neoplasia de curso indolente, com taxas de sobrevida dependentes do estádio tumoral ao diagnóstico. Este artigo descreve diretrizes baseadas em evidências clínicas para o diagnóstico, tratamento e seguimento do CMT. Objetivo O presente consenso, elaborado por especialistas brasileiros e patrocinado pelo Departamento de Tireoide da Sociedade Brasileira de Endocrinologia e Metabologia, visa abordar o diagnóstico, tratamento e seguimento dos pacientes com CMT, de acordo com as evidências mais recentes da literatura. Materiais e métodos: Após estruturação das questões clínicas, foi realizada busca das evidências disponíveis na literatura, inicialmente na base de dados do MedLine-PubMed e posteriormente nas bases Embase e SciELO – Lilacs. A força das evidências, avaliada pelo sistema de classificação de Oxford, foi estabelecida a partir do desenho de estudo utilizado, considerando-se a melhor evidência disponível para cada questão. Resultados Foram definidas 11 questões sobre o diagnóstico, 8 sobre o tratamento cirúrgico e 13 questões abordando o seguimento do CMT, totalizando 32 recomendações. Como um todo, o artigo aborda o diagnóstico clínico e molecular, o tratamento cirúrgico inicial, o manejo pós-operatório e as opções terapêuticas para a doença metastática. Conclusões O diagnóstico de CMT deve ser suspeitado na presença de nódulo tireoidiano e história familiar de CMT e/ou associação com feocromocitoma, hiperparatireoidismo e/ou fenótipo sindrômico característico, como ganglioneuromatose e habitus marfanoides. A punção aspirativa por agulha fina do nódulo, a dosagem de calcitonina sérica e o exame anatomopatológico podem contribuir na confirmação do diagnóstico. A cirurgia é o único tratamento que oferece a possibilidade de cura. As opções de tratamento da doença metastática ainda são limitadas e restritas ao controle da doença. Uma avaliação pós-cirúrgica criteriosa para a identificação de doença residual ou recorrente é fundamental para definir o seguimento e a conduta terapêutica subsequente.

Abstract
Since medullary thyroid cancer (MTC) was first recognized as a distinct tumor in 1959, it became clear that MTC is more difficult to cure than papillary thyroid cancer and has higher rates of recurrence and mortality. MTC represents 5-8% of thyroid cancers. It derives from parafollicular cells of the ultimobranchial body derived from the neural crest. MTC secretes calcitonin and other hormonal peptides and is considered part of the amine precursor uptake and decarboxilation system. MTC may occur either as a hereditary or nonhereditary entity. Hereditary MTC can occur either alone as the familial MTC or as the thyroid manifestation of multiple endocrine neoplasia (MEN) type 2 syndromes (MEN 2A MEN 2B). Activating point mutations of the RET proto-oncogene have demonstrated to be causative of the familial form of medullary thyroid cancer, both isolated familial MTC and associated with MEN 2A and 2B. In the last 10 years, major improvements and new technologies have been proposed and applied in thyroid surgery; among these are molecular diagnosis with genetic screening and mini-invasive video-assisted thyroidectomy. The history of thyroid surgery starts with Billroth, Kocher and Halsted, who developed the technique for thyroidectomy between 1873 and 1910. Prophylactic surgery for patients carrying a positive RET proto-oncogene has proven to be highly effective in curing those likely to experience the development of MTC. Video-assisted procedures with central compartment dissection have proved feasible for patients carrying a positive RET proto-oncogene. This paper reviews relevant medical literature published in the English language on surgery of MTC in well-controlled trials. We discuss the particular ethical and legal issues that thyroid prophylactic surgery raises. Searches were last updated in February 2007.

Abstract
OBJECTIVE Only few studies analysed the capability of cytology in detecting medullary thyroid cancer (MTC), and they reported a low accuracy of this diagnostic technique. Recently, calcitonin (CT) measurement in aspiration needle washout (FNA-CT) of thyroid and neck lesions has been reported as a sensitive tool for MTC. The aim of this study is to compare the sensitivity of FNA-CT and cytology in detecting MTC and to assess a cut-off value of FNA-CT for clinical practice. PATIENTS Thirty-eight MTC lesions from 36 patients were retrospectively studied, diagnosed and treated in four different centres. Furthermore, 52 nonmedullary lesions from subjects undergone biopsy following increased serum CT were collected as a control group. RESULTS Cytology detected MTC in 21/37 lesions with 56·8% sensitivity. The median FNA-CT value was 2000 pg/ml (range 58-10 000 pg/ml) in MTC and 2·7 pg/ml (range <2-13 pg/ml) in controls (P < 0·001). Using a cut-off of 39·6 pg/ml, MTC lesions could be identified with 100% sensitivity and specificity. As the most important finding, 14 histologically proved MTC lesions could be detected by FNA-CT, despite they were cytologically diagnosed as benign or nonconclusive. CONCLUSIONS This study shows, as the first in a multicentre series, that FNA-CT sensitivity is higher than that of cytology in diagnosing MTC. To avoid false-negative MTC by cytology, CT measurement in aspiration needle washout is to be performed in all patients undergoing biopsy following high serum CT.

Abstract
BACKGROUND Medullary thyroid carcinoma (MTC) is characterized by the synthesis and secretion of calcitonin (Ct). MTC without Ct secretion has been reported on rare occasions. The aim of this study was to analyze the prevalence and clinical spectrum of nonsecretory MTC in two tertiary centers that cared for 839 patients with sporadic MTC. METHODS Clinical, biochemical, histological, and immunohistological findings, and somatic RET mutations were analyzed, and long-term follow-up was documented. RESULTS Seven patients with nonsecretory MTC were identified among 839 patients with sporadic MTC; thus, the prevalence rate of nonsecretory MTC was 0.83%. In these seven patients, Ct and carcinoembryonic antigen (CEA) levels were normal when MTC was initially diagnosed in the patients, despite advanced tumor stage. Ct and CEA levels remained undetectable in four patients; recurrence was indicated in one patient after 10 years of follow-up by routine anatomic imaging and increased CEA levels, and Ct levels became slightly elevated during follow-up, despite massive tumor load, in the remaining two patients. The diagnosis of MTC was confirmed by positive immunohistochemistry for Ct, CEA, and chromogranin A. A high Ki67 proliferation index (PI) (three patients) and a high proportion of RET 918-mutated cells (four patients), as well as poorly differentiated histology, were associated with aggressive biological behavior of the MTC. The prognosis for nonsecretory MTC varied between long-term survival (12.5 years) and rapid progression leading to death within 1.75 years after diagnosis. CONCLUSIONS The prevalence of nonsecretory MTC was low (0.83% of patients with MTC). Diagnosis was often made at a clinically advanced tumor stage. The histological and immunohistological characteristics and the clinical course and prognosis of nonsecretory MTC are markedly heterogeneous. A high Ki-67 PI and a large proportion of cells with RET 918 mutations are associated with a poor prognosis.

Abstract
Carcinoembryonic antigen (CEA), a tumor marker with a glycoprotein structure, is frequently used in follow-up gastrointestinal malignancies. CEA levels may also increase in neuroendocrine tumors, including medullary thyroid carcinoma (MTC), and in some benign diseases. Patients whose blood tests show high CEA levels should have additional tests regarding MTC. Although MTC comprises only 3%-11% of all thyroid cancers, it should be tested because it has a poor prognosis and may accompany multiple endocrine neoplasia. We present the case of a 76-year-old man with subclinical hyperthyroidism with sporadic MTC who presented with initial high serum CEA levels. He underwent total thyroidectomy and left modified neck dissection. Pathologic specimens stained strongly for CEA. The patient's blood was analyzed for mutations in exons 10, 11, 13, 14, 15, and 16, but the RET proto-oncogene revealed no mutations. The patient was regularly followed by measurement of serum CEA levels and performance of positron emission tomography-computed tomography. Seventeen months after surgery, the patient has remained well and showed no signs of tumor recurrence.

Abstract
This article reviews most common types of thyroid cancer focusing on older males worldwide. Thyroid carcinoma is the most common endocrine malignancy. It includes tumour types that range from localised papillary carcinomas to lethal anaplastic disease. Among elderly population, male gender seems to be highly correlated with the risk and aggressiveness of thyroid cancer. Early diagnosis and urgent aggressive treatment are important for aging patients. This article includes numerous studies which evaluate prevalence, morbidity and mortality of thyroid cancer in older males.

Abstract
Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor of parafollicular or C-cells of thyroid that comprises 5-10% of all thyroid cancers [1, 2]. The neoplastic cells secrete calcitonin, carcinoembryonic antigen (CEA), and chromogranin A. Typically, increased serum levels of these tumor markers permit them to be used for initial diagnosis and long-term disease status surveillance. This article reports a case of sporadic MTC (pT2N0M0) in a young patient with normal serum tumor markers. A 16-year-old woman presented with MTC without evidence for this to be a familial case due to the absence of germline mutations in the RET proto-oncogene and negative family history. Surprisingly, there were normal preoperative serum levels of calcitonin, CEA, and chromogranin A, despite the immunohistochemistry showing strong and diffuse positive staining for these markers. This disparity between serum levels and tumor expression of calcitonin and CEA in MTC is quite rare. The relevant features of this case are discussed in consideration of the published experiences. This case may represent an unique subgroup of MTC with abnormal secretory capacity that requires reliance upon radiological evaluation for evidence of recurrent or disseminated disease, without the diagnostic benefit of serum tumor markers.

Abstract
BACKGROUND Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor (NET) that arises from the parafollicular cells (C-cells) of the thyroid gland which produces calcitonin (CT) and is, therefore, a serum and immunohistochemical biomarker of MTC. Here, we describe a patient with another form of NET arising with the thyroid gland. PATIENT FINDINGS This is a forty-year-old woman who underwent total thyroidectomy for a thyroid nodule that had features of an NET on fine needle aspiration. Her serum CT and carcinoembryonic antigen were normal. Surgical pathology showed a well-differentiated NET with immunohistochemical stains positive for markers of follicular cells (thyroglobulin and synaptophysin), positive for neuroendocrine markers (neuron specific enolase and chromogranin A), but negative for CT, the defining marker of MTC. CONCLUSIONS We describe a rare case of a nonmedullary NET of the thyroid gland arising from thyroid follicular cells, not parafollicular cells. We suggest that calcitonin-negative neuroendocrine tumor of the thyroid gland (CNNETT) may be an entity that has not been recognized in the literature. This distinction between MTC and CNNETT may be important, as the treatment and prognosis may differ.

Abstract
Calcitonin is a very sensitive tumor marker of medullary thyroid carcinoma (MTC). Patients with MTC have usually very high levels of serum calcitonin that can be used to diagnose the disease. In order to improve diagnostic sensitivity in family members with small MTCs or to evaluate postoperative biochemical cure status, measurement of calcitonin stimulated with combined intravenous calcium gluconate and pentagastrin has been widely adopted; however, gastrin has become unavailable. Currently, a provocative test using only calcium gluconate is performed; however, the standard values for this test have not been reported. We therefore conducted calcium gluconate stimulation tests in 20 patients before and after total thyroidectomy for thyroid diseases other than MTC. Preoperatively, the mean basal calcitonin level was 24.1 pg/mL and increased to 46.9pg/mL after calcium infusion. The ratio of the peak calcitonin level to the basal value ranged from 1- to 5.23-fold, with a mean of 1.94. The ratio was higher than 3-fold in 3 patients. In 2 patients, peak calcitonin levels exceeded 100 pg/mL. Postoperatively, the mean basal level slightly decreased to 21.15pg/mL and the response to calcium stimulation markedly decreased, with the mean ratio decreasing to 1.1-fold (range, 0.86- to 1.73-fold, maximum peak level, 33 pg/mL). Thus, some subjects without MTC show response to the calcium stimulation test up to 5.24 times the ratio and a peak value of 160 pg/mL, suggesting the requirement for judicious judgment for the early diagnosis of MTC in family members; however, after total thyroidectomy, none of the subjects showed an increase of more than 2-fold or a peak value of 33pg/mL, suggesting that responses greater than 2-fold after MTC surgery might be abnormal, indicating the presence of residual tumor.

Abstract
Abstract
Background
Not operating on patients with mild hypercalcitoninaemia (MHCT) and sporadic thyroid disease carries the risk of omitting curative surgery for medullary thyroid cancer, but systematic surgery would result in unnecessary treatment of benign pathology. This study reviewed the management of MCHT and non-hereditary thyroid disease in one centre.
Methods
MCHT was defined as an increase in basal and stimulated calcitonin levels not exceeding 30 and 200 pg/ml respectively. Over 15 years, 125 patients who presented with MCHT and sporadic thyroid disease were followed. Surgery was indicated only if there were local pressure symptoms or suspicious histomorphological changes in solitary nodules.
Results
Fifty-five patients underwent total thyroidectomy and 18 unilateral total lobectomy. Histological examination revealed medullary microcarcinoma in six patients (two women and four men). C-cell hyperplasia was found in 54 patients (74 per cent) and 13 (18 per cent) harboured no C-cell pathology. Calcitonin levels stabilized after lobectomy and became undetectable following thyroidectomy. They normalized during follow-up in a third of patients who did not have surgery.
Conclusion
Not all patients with MHCT and sporadic thyroid disease require surgery.

Abstract
BACKGROUND Inherited and sporadic medullary thyroid cancer (MTC) is an uncommon and challenging malignancy. The American Thyroid association (ATA) chose to create specific MTC Clinical Guidelines that would bring together and update the diverse MTC literature and combine it with evidence-based medicine and the knowledge and experience of a panel of expert clinicians. METHODS Relevant articles were identified using a systematic PubMed search and supplemented with additional published materials. Evidence-based recommendations were created and then categorized using criteria adapted from the United States Preventive Services Task Force, Agency for Healthcare Research and Quality. RESULTS Clinical topics addressed in this scholarly dialog included: initial diagnosis and therapy of preclinical disease (including RET oncogene testing and the timing of prophylactic thyroidectomy), initial diagnosis and therapy of clinically apparent disease (including preoperative testing and imaging, extent of surgery, and handling of devascularized parathyroid glands), initial evaluation and treatment of postoperative patients (including the role of completion thyroidectomy), management of persistent or recurrent MTC (including the role of tumor marker doubling times, and treatment of patients with distant metastases and hormonally active metastases), long-term follow-up and management (including the frequency of follow-up and imaging), and directions for future research. CONCLUSIONS One hundred twenty-two evidence-based recommendations were created to assist in the clinical care of MTC patients and to share what we believe is current, rational, and optimal medical practice.

Abstract
Calcitonin is a sensitive tumor marker for medullary thyroid cancer (MTC) and is useful in preoperative diagnosis and postoperative surveillance for recurrent disease. Calcitonin-negative MTC is a rare occurrence. We present the case of a 68-year-old man with a 6.5 cm sporadic MTC with a 5-cm metastasis in the neck, but only minimally elevated serum calcitonin levels. He underwent total thyroidectomy, resection of internal jugular vein, and limited ipsilateral lymph node dissection. He remains disease-free 12 months after surgery. We review the literature on calcitonin-negative MTC and discuss methods of postoperative surveillance in this subset of patients.

Abstract
CONTEXT Medullary thyroid carcinoma (MTC), a tumor of the parafollicular C cells of the gland, comprises 3-5% of all malignant thyroid neoplasms. Calcitonin, a polypeptidic hormone secreted by the neoplastic cells, is considered a very sensitive and specific MTC tumor marker. Patients with MTC usually present elevated serum calcitonin levels, which correlate with tumor burden and prognosis. OBJECTIVES To describe a case of advanced MTC with normal serum calcitonin and review the literature on this subject. DESIGN A case study was performed. INTERVENTION There were no interventions. PATIENTS A case of advanced MTC with normal serum calcitonin was studied. RESULTS Serum calcitonin was measured by two distinct assays, a chemiluminescent immunometric and an in-house two-site monoclonal antibody-based immunofluorometric assay. To rule out a "hook effect," or posttranslational modifications of calcitonin molecule, serum dilutions and tumor immunohistochemistry for calcitonin with the same antibodies used for serum calcitonin measurements were performed. Serum calcitonin levels were within the normal range in both assays, whereas the tumor stained strongly positive for calcitonin. These findings suggest that the tumor was able to produce but not to secrete the calcitonin protein. Five other cases of advanced MTC with normal serum calcitonin levels had been previously reported. CONCLUSIONS We present an unusual case of advanced MTC with normal serum calcitonin levels. Awareness of MTC cases presenting with normal serum calcitonin levels is important in clinical practice and is particularly relevant to centers that use this test for screening.

Abstract
Medullary thyroid cancer (MTC) is a neuroendocrine tumor derived from the C cells of the thyroid. C cells are responsible for the production of calcitonin, a sensitive and specific marker for MTC. Early detection of MTC is essential; overall survival from MTC is related to patient age, stage of disease and extent of surgical resection. Elevated preoperative serum calcitonin levels have been shown to predict the likelihood of biochemical remission postoperatively. The use of routine serum calcitonin measurements as a screening measure for MTC in patients with thyroid nodules has been advocated in Europe. To date, routine calcitonin measurement has not been widely practiced in the USA; a recent cost-effectiveness analysis suggests routine serum calcitonin measurements in patients with thyroid nodules may be comparable to other widely accepted screening programs.

Abstract
Medullary thyroid carcinoma (MTC) is a thyroid malignancy originating from C cells. To date, serum calcitonin measurement and fine-needle aspiration biopsy (FNAB) have been prominent diagnostic approaches to these lesions. Although an elevated serum calcitonin level strongly suggests the presence of MTC, this examination cannot identify the origin of the calcitonin overexpression, especially in patients demonstrating multiple thyroid nodules. For the treatment planning, it is important to know which nodule is MTC, especially in nonhereditary MTC. In this study, we propose calcitonin measurement in the washout of FNAB needles after sampling each tumor (FNAB-CT) as a new approach to diagnosis of MTC. We performed FNAB-CT for five MTC cases. Although only one of these cases was definitively diagnosed as having MTC by FNAB cytology, FNAB-CT values ranged from 17,000 to 560,000 pg/mL, which were exceedingly higher than those of 11 controls (seven papillary carcinomas, two adenomatous nodules, one chronic thyroiditis, and one normal thyroid), which showed values ranging from <10 to 67 pg/mL. In patients with MTC, FNAB-CT values were 74 to 1888 times greater than serum calcitonin values. These findings suggest that FNAB-CT can be an additional approach to diagnosis of MTC.

Abstract
It has been reported that the thyroid is relatively immune to malignant metastasis. Therefore, in a practical setting, it is difficult to diagnose whether synchronous nodules in both lung and thyroid are independent or have metastasized from one to the other. In the present study, we report a treatment approach in a patient with such nodules, using a molecular technique. A 68-year-old woman presented with synchronous solitary thyroid mass and a nodular lesion in the right lung. Both tumors, which were surgically resected, morphologically showed neuroendocrine differentiation, which was confirmed by immunohistochemical analysis. These features required differential diagnosis from possible (1) medullary thyroid carcinoma (MTC) with metastasis to the lung, (2) pulmonary neuroendocrine carcinoma with metastasis to the thyroid, and (3) independent MTC and pulmonary neuroendocrine carcinoma. Identical mutations of the p53 gene were detected in both the thyroid and lung tumors, indicating the same origin for both tumors. In addition, these mutations and a lack of calcitonin expression suggested a pulmonary origin of the tumors. Metastatic thyroid cancers are well known to cause miliary lesions in the lung, while lung cancers can metastasize to various tissues. Furthermore, pulmonary neuroendocrine carcinoma has been reported as having a tendency of metastasizing to the thyroid. Head and neck surgeons should be aware that a particular subset of lung cancers may develop a metastatic solitary nodule in the thyroid, as presented. An effective therapeutic strategy is largely dependent on the differential diagnosis.

Abstract
Medullary thyroid carcinoma (MTC) is a relatively rare thyroid malignancy of C-cell origin that secretes calcitonin. Although its varied cytomorphologic features are well described in literature, very little is mentioned about the morphologic manifestation of its secretory activity. This study, based on nine fine needle aspiration (FNA) samples from eight MTC patients, is an attempt to present the varied cytomorphologic features suggesting secretory activity in MTC as observed in Papanicolaou and MGG stained FNA smears and correlate them with the immunocytochemical (ICC) staining for calcitonin performed on FNA smears and the serum calcitonin values. The average number of cells in these nine samples was as follows: oval/triangular/plasmacytoid (56.7%), small round (23.6%), spindle-shaped (12.7%), and miscellaneous (7.1%). The cytomorphological features suggesting secretory activity, viz., fine cytoplasmic vacuoles, azurophillic granules, marginal vacuoles, and intracytoplasmic lumina (ICL) with secretions were present in eight, eight, five, and six samples, respectively. Material likely to be amyloid, based on morphological features, was present extracellularly in three samples and both intracellularly and extracellularly in six samples. Immunocytochemically, all the nine samples stained for calcitonin and all the three stained for chromogranin showed positive cytoplasmic reaction in the neoplstic cells. The background amyloid (in six samples), the coarse cytoplasmic granules (in two samples), and the contents of ICL (in one sample) were found to be positively stained for calcitonin. The intracytoplasmic secretory material appeared to be diffusing out of some cells both in the routine MGG stained smears and in the smears stained for calcitonin. Histopathology reports of seven samples in six patients confirmed the cytodiagnosis of MTC in all. Baseline serum calcitonin values in three cases and postoperative serum calcitonin levels during follow-up in three others were high. Thus, our study highlighted the morphological manifestations of secretory activity in MTC and the nature of secretory material as calcitonin, supported by immunocytochemical staining and serum calcitonin level.

Abstract
Background Medullary thyroid carcinomas (MTC) constitute about 5 to 7 % of thyroid neoplasms. They originate from parafollicular C cells which produce Calcitonin, a hormone which has an impact on calcium metabolism and represents the biochemical activity of MTC. In rare cases pre-operative serum calcitonin can be negative. Case presentation We report on a 73-year-old female patient with a rare case of a serum calcitonin negative medullary thyroid carcinoma who suffered fulminant post-operative course and died of multiple metastasis. Conclusion This case shows that in very rare cases MTCs do not secrete calcitonin making diagnosis and tumour follow-up difficult. To this date, only few reports describing this combination of circumstances were found in the English literature.

Abstract
MTC is a rare neuroendocrine thyroid tumour accounting for 3% to 10% of all thyroid malignancies. It can occur in a sporadic and a hereditary clinical setting. Hereditary MTC may either occur alone (familial MTC, FMTC) or as part of multiple endocrine neoplasia (MEN) type 2A, or MEN 2B. These disorders are due to germline mutations in the RET (REarranged during Transfection) gene. In carriers of MEN 2B-associated RET mutations, prophylactic thyroidectomy is indicated before the first year of life. In the case of MEN 2A-associated germline RET mutations with a high-risk profile, total thyroidectomy is warranted before the age of 2 years and certainly before the age of 4 years. At that age the risk of invasive MTC and metastases is acceptably low. Depending on the type of RET mutation, thyroidectomy can take place at an older age in patients with a lower risk profile. In case of elevated basal or stimulated serum calcitonin, preventive surgery including total thyroidectomy and central compartment dissection should be performed regardless of age. When MTC presents as a palpable tumour, total thyroidectomy should be combined with extensive lymph node dissection of levels II-V on both sides and level VI to prevent locoregional recurrences.

Abstract
INTRODUCTION Medullary thyroid carcinoma (MTC) originates from the thyroid parafollicular cells and accounts for 3% to 10% of all thyroid malignancies. Approximately 84% of cases are sporadic. The aim of this study was to evaluate the outcomes of treatment for sporadic medullary thyroid carcinoma (SMTC) and define the prognostic factors for overall survival. METHODS The records of 32 SMTC patients treated at Ankara Oncology Education and Research Hospital between September 1993 and April 2003 were retrospectively evaluated. The effects of age, gender, tumor localization, extent of the primary surgical resection, tumor size, capsule invasion, lymph node metastasis, extranodal extension, tumor stage, local recurrence, and distant metastasis on the overall survival rate were evaluated by univariate and multivariate analyses. RESULTS There were 32 patients (19 females, 13 males) with a median age of 45 years (21-76 years). Altogether, 22 patients had undergone complete resection and 10 patients incomplete resection. The median follow-up was 48 months (9-111 months), and the overall 5-year survival rate was 51%. Based on the univariate analysis, the extent of primary surgical resection, pathologic tumor size, capsule invasion, lymph node invasion, extranodal extension, tumor stage, local recurrence, and distant metastasis were factors that significantly affected survival. In the multivariate analysis, however, only the extent of the primary surgical resection, capsule invasion, and distant metastasis were found to be statistically significant factors. CONCLUSIONS The extent of the primary surgical resection significantly influences the survival of patients with SMTC. Capsule invasion and distant metastasis were additional factors affecting the prognosis.

Abstract
To identify patients with medullary thyroid carcinoma (MTC) at a potentially curable stage of the disease, serum concentrations of calcitonin (hCT) were determined in 14,000 patients (including 10,158 patients with thyroid nodules) referred to a thyroid outpatient clinic. Excluding patients in whom elevated basal hCT concentrations had already been known at the time of their referral, 507 patients with thyroid nodules presented basal concentrations of hCT of more than 10 pg/ml. Following stimulation by IV pentagastrin (0.5 microg/kg BW), hCT concentrations of more than 100 pg/ml were seen in 103 patients. This group included 32 new cases of MTC (29 patients with sporadic MTC and 3 new index cases of the familial form) and 43 patients with C cell hyperplasia (CCH). Among the 3,843 patients without thyroid nodules, 2 were found to harbor sporadic MTC while 4 had CCH. As compared to 1.1 cases of MTC per 1,000 patients with nodular thyroid diseases diagnosed in our institution before hCT screening was begun, 3.2 cases of MTC per 1,000 patients were identified when hCT was determined in all patients with thyroid nodules. The determination of hCT in all patients with thyroid nodular disease facilitates the timely diagnosis of MTC, thus providing the chance of curative surgery.

Abstract
BACKGROUND AND OBJECTIVES Preoperative diagnosis of sporadic medullary thyroid carcinoma (MTC) has mainly relied on fine needle aspiration cytology (FNAC). The present study aimed to compare the sensitivity of this technique with serum calcitonin (CT) measurement and to assess the therapeutic implications of an inadequate preoperative diagnosis. METHODS We reviewed the clinical records of 91 MTC patients treated and/or followed at our institution between January 1990 and December 2003. RESULTS After revision of clinical records, 77 individuals were considered eligible for the study. FNAC was performed in 67 patients (87%) with a sensitivity of 63%; serum CT was measured in 56 patients (73%) with a sensitivity of 98%. Both FNAC and serum CT were assessed in 51 patients (66%). FNAC detected only 74.5% of MTCs suspected by elevated serum CT. Among patients with a cytological diagnosis of MTC, total thyroidectomy (TT) was performed in 95% of patients. Among patients without a cytological diagnosis of MTC, TT was performed in 83% of patients in whom serum CT was evaluated prior to surgery whereas it was performed in only 46% of patients in whom CT evaluation was lacking. CONCLUSIONS Despite the higher sensitivity of serum CT measurement, as compared with FNAC to diagnose MTC (98% vs. 63%), only 9% of patients might have escaped to surgery based on FNAC results. However, indication for surgery based on suspicious FNAC may not alert the surgeon for the need of a TT and exploration of nodes at least in the central compartment.
