Abstract
Background Medullary thyroid carcinoma (MTC) is a rare type of thyroid cancer that occasionally occurs as part of MEN2A. The universal treatment of MTC is total thyroidectomy with central lymph node dissection. For disease progression, carcinoembryonic antigen (CEA) and calcitonin (CTN) need to be followed. Our aim was to study the presence and patterns of the above-mentioned characteristics of MTC in our population. Methodology This retrospective study was conducted in a tertiary care hospital of Pakistan in which data of thirty-two medullary thyroid cancer patients over the past 20 years were reviewed and analysed after fulfilment of inclusion criteria. Their clinical, pathological, biochemical and treatment modalities were recorded through a retrospective review of their medical record files. Results The mean age of patients was 42.88 ± 2.67 years in our study, with a male-to-female ratio of 2:1. Patients with sporadic MTC were 68.8%, while 31.2% were familial. The rates of metastasis were highest in bones followed by lungs and liver. Total thyroidectomy was performed in 26 (81.2%) patients and among those chemotherapy and XRT were performed in one and two patients, respectively. Histologically, the mean tumour size was 7.62 ± 3.64 cm. Median pre-surgery calcitonin was 5756 pg/ml that decreased to 29.3 pg/ml post-surgery. Median pre-surgery CEA level was 246.5 ng/ml that decreased to 6.39 ng/ml post-surgery. Two patients were RET positive. Conclusion MTC usually presents in the fourth decade of life with male predominance and mostly sporadic occurrence. Total thyroidectomy with subsequent serial calcitonin and CEA levels thereafter are the mainstay of treatment and follow-up.

Abstract
BACKGROUND Medullary thyroid carcinoma (MTC) in the context of multiple endocrine neoplasia type 2 (MEN2) is caused by mutations in the RET proto-oncogene. Therefore, in children with MEN2 and advanced MTC, the RET tyrosine kinase (TK) pathway is a target for treatment with selpercatinib, a selective RET TK inhibitor. PATIENTS AND METHODS A retrospective review of the clinical, genetic, biochemical (calcitonin and carcinoembryonic antigen [CEA]) and imaging data of six medically untreated children with MEN2 and recurrent and or progressive MTC. The main parameters were safety and objective treatment response to selpercatinib. RESULTS Six children (three males and three females, aged 3-12 years), four with MEN2B and two MEN2A, are reported. All had initial total thyroidectomy and extensive neck dissections but subsequently developed recurrent and progressive disease. All experienced an improvement in clinical symptoms with a concomitant biochemical response evidenced by significant fall in serum calcitonin and CEA concentrations. The fall in serum calcitonin was evident within 2 weeks of the start of selpercatinib, and responses were ongoing at a median follow-up of 13 months (range, 11-22 months). Four children with measurable radiological disease had good volume reduction. The most common adverse effects were transient but reversible grade 1 or 2 increase in alanine aminotransferase, serum bilirubin and constipation. No child required a dose modification or had to discontinue selpercatinib because of a drug-related adverse event. CONCLUSION Selpercatinib has shown excellent therapeutic efficacy with minimal toxicity in children with MEN2 and progressive metastatic RET-mutated MTC.

Abstract
Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor originating from the parafollicular cells. The diagnostic and therapeutic strategies for the condition are different from those used for well-differentiated thyroid cancer. Since the 2015 American Thyroid Association guidelines for the diagnosis and treatment of MTC, the latest, including the National Comprehensive Cancer Network and European Association for Medical Oncology guidelines have been updated to reflect several recent advances in the management of MTC. Advances in molecular diagnosis and postoperative risk stratification systems have led to individualized treatment and follow-up strategies. Multi-kinase inhibitors, such as vandetanib and cabozantinib, can prolong disease progression-free survival with favorable adverse effects. In addition, potent selective rearranged during transfection (RET) inhibitors (selpercatinib and pralsetinib) have shown a promising efficacy in recent clinical trials. This review summarizes the management of MTC in recent guidelines focused on sporadic MTC.

Abstract
Aims Serum calcitonin (CT) assay is commonly used in the diagnosis and follow-up of medullary thyroid carcinoma (MTC). The aim of this study was to ascertain whether serum CT levels, measured in the first few days after surgery, could be used to evaluate the efficacy of treatment. Methods A group of 33 patients was studied. In all patients the follow-up was more than 20 months. Results Preoperatively basal CT serum levels were high in all patients. Twenty-four hours after surgery CT serum levels dropped to within the normal range in 8 patients and 72 hours after operation in 7 others. In this group 1 patient was at stage I, 11 at stage II and 3 at stage III. Basal and pentagastrin stimulated CT levels continued to be in the normal range in these 15 patients 6 and 12 months after surgery and at the subsequent year by follow-up visits. No clinical or radiological evidence of disease was found during the follow-up in this group. In the other 18 patients CT was reduced but still high 72 hours after surgery; 6 months later basal serum CT levels continued to be elevated or responsive to pentagastrin stimulation. In this group restaging showed tumor relapse in the thyroid bed in 2 patients, cervical lymphadenopathy in 11, and distant metastases (bone, liver) in 3. Conclusions Immediate postoperative CT serum levels seem to be the most useful index to evaluate the efficacy of surgical treatment and the presence of residual neoplastic tissue.

Abstract
BACKGROUND For detecting tumor recurrence of medullary thyroid carcinoma (MTC) in the neck, an appropriate frequency and interval of postoperative ultrasonography (US) surveillance remains unclear. This study aimed to assess an appropriate interval and frequency of postoperative neck US surveillance for detecting tumor recurrence in patients who had undergone thyroid surgery due to MTC. METHODS A total of 86 patients who had undergone thyroid surgery for the treatment of MTC and had at least one postoperative US follow-up examination at any of nine affiliated hospitals were included. Postoperative follow-up US, clinical, and histopathological results of patients were reviewed. The tumor recurrence/persistence rate of MTC was investigated, and the interval and session number of postoperative follow-up US and clinicopathologic factors were compared between tumor recurrence/persistence and non-recurrence groups. RESULTS Of the 86 patients, 22 (25.6%) showed tumor recurrence/persistence. Of the 22 patients with tumor recurrence/persistence, 11 (50%) showed structural recurrence/persistence in the neck on follow-up US. In these 11 patients, the mean interval and session number of postoperative follow-up US between initial surgery and the first US detection of recurrence/persistence was 41.3 ± 39.3 months (range, 6-128 months) and 2.6 ± 2.3 (range, 1-8), respectively. On follow-up US, 6 (54.5%, 6/11) were diagnosed with tumor recurrence/persistence within 3 years of the initial surgery. Tumor recurrence/persistence was significantly correlated with TNM stage (p < 0.001) and multiplicity/bilaterality (p = 0.013). CONCLUSION For detecting MTC recurrence/persistence, postoperative US surveillance at 1-year intervals may be sufficient within the first 3 years after thyroid surgery, but depending on the presence of relevant risk factors, annual or biannual US surveillance may be recommendable for 4-10 years after thyroid surgery.

Abstract
This article summarizes the main principles for the appropriate use of laboratory testing in the diagnosis and management of thyroid disorders, as well as controversies that have arisen in association with some of these biochemical tests. To place a test in perspective, its sensitivity and accuracy should be taken into account. Ordering the correct laboratory tests facilitates the early diagnosis of a thyroid disorder and allows for timely and appropriate treatment. This article focuses on a comprehensive update regarding thyroid-stimulating hormone, thyroxine/triiodothyronine, thyroid autoantibodies, thyroglobulin, and calcitonin. Clinical uses of these biochemical tests are outlined.

Abstract
Background: Medullary thyroid cancer (MTC) is an endocrine tumor featuring parafollicular or C-cell differentiation,
with calcitonin as a specific biomarker in MTC diagnosis. Germline mutations in the RET proto-oncogene are considered
responsible for its familial occurrence and somatic mutations can cause sporadic lesions. MicroRNAs can act as
oncogenes or tumor suppressors by inhibiting the expression of target genes.. The aim of this study was to investigate
relationships between plasma levels of calcitonin and miRNA323 expression in MTC patients with or without RET
mutation. Methods: In this cross-sectional study, MTC lesions (based on pathological confirmation) were investigated.
Genomic DNA was extracted and Exons 10 and 11 of RET were genotyped using PCR-sequencing. Division was into
two groups of 43 cases each with or without mutation. Plasma levels of calcitonin were determined in both. Results:
miRNA323 was measured using real-time-PCR. After performing normality tests, independent T-tests and Mann
Whitney tests were used for the statistical comparison of parametric and nonparametric data, respectively. Plasma
levels of calcitonin were significantly higher in MTC cases without a RET mutation compared to those with a mutation.
Conclusion: There was no significant difference between the two groups regarding the expression of miRNA323 so
that this parameter could not be used as a bio-index germ line mutations in MTCs. However, determination of calcitonin
levels in plasma might be helpful in this regard.

Abstract
Sporadic Medullary Carcinoma of the Thyroid is a relatively uncommon entity and at the time of diagnosis, most already present loco-regional metastasis. Therapy should be aggressive to reduce recurrence and mortality. Follow-up period should continue lifelong and should also include calcium/pentagastrin infusion test, as well as 6-month interval diagnostic imaging.

Abstract
BACKGROUND Risk stratification in medullary thyroid cancer (MTC) has traditionally relied on standardized anatomic staging systems that, despite providing valuable prognostic information, do not adequately predict the risk of persistent or recurrent disease. As dynamic risk stratification has been demonstrated to be clinically valuable in nonmedullary thyroid cancer, we adapted our response to therapy definitions in order to apply them to MTC. In this study, we evaluate and compare the clinical utility of our previously proposed MTC response to therapy stratification with a traditional standardized anatomic staging system. METHODS Both the Tumor, Node, Metastasis/American Joint Cancer Committee (TNM/AJCC) staging system and our previously proposed response to initial therapy staging system was evaluated in 287 MTC patients followed for a median of five years. RESULTS The TNM/AJCC staging system provided adequate risk stratification with regard to disease-specific mortality and the likelihood of having no evidence of disease at final follow-up, but did not adequately stratify patients with regard to the likelihood of having structural persistent disease, biochemical persistent disease, or recurrence. However, the response to initial therapy risk stratification system provided clinically useful risk stratification with regard to disease-specific mortality, the likelihood of having no evidence of disease at final follow-up, the likelihood of having a biochemical persistent disease at final follow-up, and the likelihood of having structural persistent disease at final follow-up. Furthermore, the response to therapy risk stratification system demonstrated a higher proportion of variance explained (54.3%) than the TNM/AJCC system (23.9%). CONCLUSION Our data demonstrate that a dynamic risk stratification system that uses response to therapy variables to adjust risk estimates over time provides more useful clinical prognostic information than static initial anatomic staging in MTC thyroid cancer.

Abstract
Introdução O carcinoma medular de tireoide (CMT) origina-se das células parafoliculares da tireoide e corresponde a 3-4% das neoplasias malignas da glândula. 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
PURPOSE OF REVIEW To weigh the clinical impact of new technological insights into heritable thyroid malignancies. RECENT FINDINGS Medullary thyroid carcinoma and familial nonmedullary thyroid cancers represent the small minority of thyroid cancers that are inherited. New insights into the genetic alterations and molecular mechanisms implicated in these tumors are serving to refine the clinical tools available for their initial diagnosis as well as subsequent follow-up. In addition to an analysis of rearranged during transfection mutations and calcitonin profiles in medullary thyroid carcinoma, this review includes emphasis on familial nonmedullary thyroid cancer syndromes, including genetic findings in familial papillary thyroid cancer, familial adenomatous polyposis, Cowden syndrome, Carney complex, and Werner syndrome. SUMMARY Genetic mutational information is increasingly available on medullary and familial nonmedullary thyroid cancer and their associated syndromes. The clinical significance of this information for affected patients and their families continues to undergo evaluation.

Abstract
Medullary thyroid carcinoma (MTC) accounts for 5-8% of all thyroid cancers. MTC is mainly sporadic in nature, but an hereditary pattern [multiple endocrine neoplasia type 2 (MEN 2)] is present in 20-30% of cases, transmitted as an autosomal-dominant trait due to germline mutations of the RET proto-oncogene. About 98% of patients with MEN 2 have germline mutations in exons 5, 8, 10, 11, 13, 14, 15 or 16 of the RET gene. The primary treatment of both hereditary and sporadic forms of MTC is total thyroidectomy and removal of all neoplastic tissue present in the neck. The therapeutic option for lymph node surgery should be dictated by the results of presurgical evaluation. After total thyroidectomy, measurements of serum calcitonin (CT) and carcinoembryonic antigen are of paramount importance in the postsurgical follow-up of patients with MTC as they reflect the presence of persistent or recurrent disease. Complete remission is demonstrated by undetectable and stimulated serum CT measurement. On the contrary, if serum CT is detectable under basal conditions or becomes detectable after stimulation, the patient is probably not cured, but imaging techniques will not demonstrate any disease until serum CT approaches levels >150 pg/ml. The tumour metastasises early to both paratracheal and lateral cervical lymph nodes. Metastases outside the neck may occur in the liver, lungs, bones and, less frequently, brain and skin. Surgery is the main treatment for local and distant metastases whenever feasible. Systemic chemotherapy with dacarbazine, 5-fluorouracil and doxorubicin (alone or in combination) has shown very limited efficacy, achieving only partial responses in the range of 10-20% and of short duration. Several kinase inhibitors are currently under evaluation and preliminary results are promising. Familial cases must be identified by searching for RET proto-oncogene mutations in the proband and in family members. Carriers of the RET gene are candidates for prophylactic thyroidectomy at different ages depending on the risk associated with the specific RET mutations.

Abstract
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.

Abstract
CONTEXT In the management of patients with medullary thyroid carcinoma (MTC), calcitonin doubling time (dt) has gained interest as an independent predictor of recurrence and survival. OBJECTIVE To perform a structured meta-analysis of the diagnostic value of calcitonin dt, carcinoembryonic antigen (CEA) dt and the combination and to define dt strata with the highest predictive power. Design The study was a meta-analysis using individual data. METHODS Ten studies containing data on the post-operative kinetics of tumour marker(s) and (recurrence free) survival were included. RESULTS Calcitonin- and CEA-dt are significant indicators for survival (hazard ratios (HR) 21.52 respectively infinite for dt 0-1 year compared to dt >1 year) and recurrence (HR 5.33 respectively 6.80 for dt 0-1 year compared to dt >1 year). The highest predictive power was found for the dt classification 0-1 year vs. >1 year. CEA dt has a higher predictive value than calcitonin dt in the subgroup of patients for which both parameters were available. CONCLUSION The dts of both calcitonin and CEA are strong prognostic indicators for MTC recurrence and death. CEA dt has a higher predictive value than calcitonin dt and therefore measuring both tumour markers is essential for proper risk stratification.

Abstract
Tumor localization is difficult in patients with medullary thyroid carcinoma (MTC) that have persistent hypercalcitoninemia after thyroidectomy. In this study, the (11)C-methionine positron emission tomography/computed tomography (PET/CT) was compared with the (18)F-FDG PET/CT for diagnostic sensitivity in detecting residual or metastatic disease. (11)C-methionine PET/CT and (18)F-FDG PET/CT were performed on 16 consecutive patients with MTC that had persistent hypercalcitoninemia after surgery in this prospective, single-center study. Patient- and lesion-based analyses were performed using a composite reference standard which was the sum of the lesions confirmed by all combined modalities, including neck ultrasonography (US) with or without fine needle aspiration cytology, CT, bone scan, magnetic resonance imaging (MRI), and surgery. By patient-based analysis, the sensitivities of (11)C-methionine PET/CT and (18)F-FDG PET/CT were both 63%. By lesion-based analysis, the sensitivity of (11)C-methionine PET/CT was similar to (18)F-FDG PET/CT (73% vs. 80%). Excluding hepatic lesions, which could not be detected because of physiological uptake of methionine by the liver, the sensitivity of (11)C-methionine PET/CT was better than (18)F-FDG PET/CT especially for detecting cervical lymph node lesions; however, it was not superior to US. All patients with serum calcitonin levels ≥370 pg/mL showed uptake by (11)C-methionine PET/CT and (18)F-FDG PET/CT. This preliminary data showed that despite its similar sensitivity to (18)F-FDG PET/CT for detecting residual or metastatic MTC, (11)C-methionine PET/CT provided minimal additional information compared to combined (18)F-FDG PET/CT and neck US.

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
BACKGROUND The decrease of calcitonin levels after curative operation in patients with medullary thyroid cancer is characterized by individual variation; therefore, intraoperative calcitonin measurements to evaluate the completeness of the resection seem to not be feasible. The aim of this study was to evaluate whether an intraoperative pentagastrin test after thyroidectomy and central neck dissection is useful to predict lymph node involvement of the lateral neck. METHODS A group of 30 consecutive patients underwent primary surgery. After thyroidectomy and dissection of the central lymph node compartment, an intraoperative pentagastrin test was performed. Biochemical and histologic data were compared retrospectively. RESULTS Of the group, 20 patients (67%) showed no, or only central neck lymph node, involvement and no increase in calcitonin after intraoperative stimulation. Lymph node involvement was documented histologically in the lateral neck of 10 patients (33%), and 8 patients showed an increase of calcitonin as an indication of lymph node involvement. In two patients, each with 1 single micrometastasis in the lateral neck, the intraoperative pentagastrin test was negative. CONCLUSIONS Intraoperative calcitonin monitoring after pentagastrin stimulation seems promising in predicting lymph node involvement of the lateral neck to aid selection of patients for lateral lymph node dissection. The development of a highly sensitive, quick calcitonin assay is imperative.

Abstract
Medullary thyroid carcinoma (MTC) is a rare malignancy of the thyroid C cells. It occurs in hereditary (25% of cases) and sporadic forms, and aggressiveness is related to the clinical presentation (hereditary vs. sporadic) and the type of RET mutation present. In hereditary cases, early diagnosis makes preventative surgery possible. In established cases, thorough surgical extirpation of the primary tumor and nodal metastases has been the mainstay of treatment. Radioactive iodine, external beam radiation therapy (EBRT), and conventional chemotherapy have not been effective. Newer systemic treatments, with agents that target abnormal RET proteins, hold promise and are being tested in clinical trials for patients with metastatic disease.

Abstract
Medullary thyroid carcinoma (MTC) is a rare malignancy with several distinctive features that distinguish its management from other thyroid cancers. First, MTC may be sporadic (75% of cases), or may occur as a manifestation of the hereditary syndrome Multiple Endocrine Neoplasia type 2 (MEN 2) (25% of cases). Additionally, while MTC is more difficult to cure than differentiated thyroid cancer and has higher rates of recurrence and mortality, it is usually a slow growing tumor compared with other malignancies. Finally, unlike differentiated thyroid cancer, there is no known effective systemic therapy for MTC. MTC cells do not concentrate radioactive iodine, and MTC does not respond well to external beam radiation or conventional cytotoxic chemotherapy. These distinguishing features should be considered in planning surgical management of MTC.

Abstract
Medullary thyroid carcinoma (MTC) is a neuroendocrine malignancy that occurs in hereditary (25%) and sporadic (75%) clinical settings. MTC is present in all patients with the multiple endocrine neoplasia type 2 syndromes. MTCs produce calcitonin, the measurement of which can indicate the presence of tumors in people who are at risk and the effectiveness of therapy in treated patients. Surgical cure is possible in young patients with multiple endocrine neoplasia type 2 who undergo preventative thyroidectomy (approximately 50% of patients who are diagnosed with a palpable thyroid mass) and in some patients with recurrent nodal metastatic disease in the neck. Mortality from MTC is caused by tumor invasion of the trachea, great vessels in the neck, or mediastinum or by the effects of distant metastatic disease. Surgery for cervical recurrence can prevent death from tracheal invasion. The role of radiation therapy is not well defined. There is no effective systemic therapy for MTC. Activating mutations in a tyrosine kinase receptor gene (RET) are present in most MTCs, and experience with tyrosine kinase inhibitors and other agents in clinical trials is critical for the identification of effective systemic treatment.

Abstract
AIMS Exposure to bacterial endotoxin, perhaps due to bowel congestion or ischaemia and altered gut permeability, may result in immune activation that is characteristic for patients with severe heart failure. It is known that blood procalcitonin rises in response to bacterial endotoxin exposure. METHODS We measured procalcitonin in a group of 29 patients with acute cardiogenic shock and no sign of infection (all without bacteraemia) and 26 with septic shock. Blood was analysed for procalcitonin, interleukin-6, tumour necrosis factor-alpha (TNF-alpha), c-reactive protein (CRP) and neopterin. Patients were managed conventionally in an intensive care unit with no further experimental procedures. RESULTS Three cardiogenic (10%) and seven septic shock patients (27%) survived. Most patients with acute heart failure surviving 12 h or more (18 of 20) developed a pyrexia (738.0 degrees C) of unknown origin in the absence of positive cultures, with a rise in procalcitonin (1.4+/-0.8 to 48.0+/-16.2 ng/ml, P<0.001), CRP (76.5+/-16.4 to 154.7+/-22.9 mg/l, P<0.001) and neopterin (20.7+/-3.5 to 41.2+/-6.7 nmol/l, P<0.001). Patients with septic shock had higher initial levels of cytokines, and higher peak levels. Those with heart failure surviving (n=3) and those dying in the first 12 h (n=9) had no rise in cytokine levels. The patients with high procalcitonin had a higher temperature (38.9+/-0.3 vs. 37.3+/-0.23 degrees C, P<0.05), TNF-alpha (43.95+/-9.64 vs. 16.43+/-4.33 pg/ml; P<0.005) and CRP (146.1+/-18.4 vs. 68.2+/-39.6 mg/ml, P<0.005). Peak procalcitonin levels correlated with peak temperature (r=0.74, P<0.001). CONCLUSION Cardiogenic shock causes a pyrexia of unknown origin in patients surviving for 12 h and that is associated with a rise in procalcitonin levels. This lends support to the hypothesis that patients with cardiogenic shock may be being exposed to bacterial endotoxin at a time when bowel wall congestion and or ischaemia is likely to be present.

Abstract
OBJECTIVE To establish the frequency, pattern and location of cervical lymph node metastases from palpable medullary thyroid carcinoma (MTC). Recommendations are made regarding the extent of surgery for this tumor. SUMMARY BACKGROUND DATA Medullary thyroid carcinoma is a tumor of neuroendocrine origin that does not concentrate iodine. Surgical extirpation of the thyroid tumor and cervical node metastases is the only potentially curative therapeutic option. Patterns of node metastases in the neck and guidelines for the extent of dissection for palpable MTC are not well established. METHODS Seventy-three patients underwent thyroidectomy for palpable MTC with immediate or delayed central and bilateral functional neck dissections. The number and location of lymph node metastases in the central (levels VI and VII) and bilateral (levels II to V) nodal groups were noted and were correlated with the size and location of the primary thyroid tumor. Intraoperative assessment of nodal status by palpation and inspection by the surgeon was correlated with results of histologic examination. RESULTS Patients with unilateral intrathyroid tumors had lymph node metastases in 81% of central node dissections, 81% of ipsilateral functional (levels II to V) dissections, and 44% of contralateral functional (levels II to V) dissections. In patients with bilateral intrathyroid tumors, nodal metastases were present in 78% of central node dissections, 71% of functional (levels II to V) node dissections ipsilateral to the largest intrathyroid tumor, and 49% of functional (levels II to V) node dissections contralateral to the largest thyroid tumor. The sensitivity of the surgeon's intraoperative assessment for nodal metastases was 64%, and the specificity was 71%. CONCLUSION In this series, >75% of patients with palpable MTC had associated nodal metastases, which often were not apparent to the surgeon. Routine central and bilateral functional neck dissections should be considered in all patients with palpable MTC.

Abstract
Residual or recurrent medullary thyroid carcinoma (MTC), manifested by elevated calcitonin levels, occurs commonly following primary treatment of MTC. Re-operation in appropriately selected patients is the only treatment modality which consistently and reliably reduces stimulated calcitonin levels, and results in excellent local disease control. We report improved results of surgical management of recurrent MTC in two consecutive series of patients. In our most recent series (1992-96), 38% of patients (17 out of 45) had normal postoperative stimulated calcitonin levels, compared to 28% (nine of 32) in our first series (1990-92). In the most recent series, only 13% (six of 45) of patients had no decrease in calcitonin levels following re-operation, compared to 31% (10 of 32) in our first series (P = 0.07, Fisher's exact test). This improvement has mainly occurred through better preoperative selection of patients, and the institution of routine laparoscopic liver examination preoperatively, which identified metastases in 10 patients, nine of whom had normal CT or MRI imaging.

Abstract
OBJECTIVE The purpose of the study is to determine whether reoperation for medullary thyroid carcinoma (MTC), performed with low morbidity in carefully selected patients, consistently results in improvement as determined by lowering of stimulated calcitonin levels. BACKGROUND Persistent or recurrent elevation of stimulated plasma calcitonin levels occurs in > 50% of patients after primary operation for MTC. Success of reoperation with clearance of metastatic cervical nodal disease has been hampered by failure to identify patients with distant metastases and by inadequate removal of involved nodal groups. METHODS Since 1992, the authors have evaluated 115 patients with recurrent or residual MTC. Fifty-three patients have not undergone operation because of extent of disease, previous extensive treatment, medical condition, or patient choice. Sixty-two patients underwent surgery. Ten patients had laparoscopic or open examination of the liver, the results of which showed liver metastases. Seven patients had palliative debulking of cervical tumor. In 45 patients without evidence of distant metastases, cervical operation was carried out with curative intent. Removal of central, upper mediastinal, and lateral nodes (levels II, III, IV, VI, and VII) was done. RESULTS Seven of eight patients who had palliative resections are alive without symptoms. In patients who underwent curative resections, postoperative stimulated calcitonin levels were in the normal range in 17 patients (38%) and were not significantly lowered in 6 patients (13%). There were no deaths, and no transfusions were used. CONCLUSIONS These results are a significant improvement over the authors' previous series and reflect better preoperative identification of patients with disease confined to the neck and improved operative strategy based on knowledge of the pattern of nodal spread of MTC.

Abstract
BACKGROUND Patients operated on for medullary thyroid carcinoma (MTC) frequently have persistent elevated plasma calcitonin concentrations after operation, indicating remaining tumor. The plasma calcitonin concentration in a patient with MTC roughly reflects the endogenous tumor burden. The only effective treatment for MTC is surgical. The decision about whether a patient with persistent MTC should have a repeat operation would be influenced by knowledge of the natural course of the disease. METHODS Forty patients with persistently elevated peak plasma calcitonin concentrations after thyroidectomy for MTC were monitored for a mean of 6 years. Serial determinations of plasma calcitonin levels were obtained before and after intravenous injection of calcium and pentagastrin. RESULTS At the first postoperative test 63% of the patients had undetectable basal calcitonin values, although their stimulated plasma calcitonin concentrations were elevated. The mean annual increase in stimulated plasma calcitonin concentrations was 117%, but plasma calcitonin concentrations were stable in three patients and decreased in one patient. Five patients are known to have experienced distant metastases. CONCLUSIONS MTC is a progressive disease in most patients with persistent hypercalcitoninemia after thyroidectomy. Stimulated peak plasma calcitonin levels are more meaningful than basal levels in the serial postoperative evaluation of patients with persistent hypercalcitoninemia after thyroidectomy for MTC.

Abstract
Between 1977 and 1990 we operated on 33 patients with medullary thyroid carcinoma. We performed total thyroidectomy in 31 patients and central node dissection and/or lateral modified node dissection in 21 patients (63.3%). Two patients underwent radiotherapy after subtotal resection and tracheostomy. No perioperative death occurred. Twenty-five patients were followed (mean follow-up, 63.8 months) and 8 others were unavailable for follow-up. Three patients (1 with multiple endocrine neoplasia type IIB, 2 sporadic with distant metastases) died of their disease at 12, 18 and 36 months after initial operation. Of the remaining 22 patients, 4 with stage II disease were normocalcitoninemic even with pentagastrin stimulation, following total thyroidectomy and bilateral modified neck dissection and central node dissection. Eighteen other patients continued to have elevated calcitonin levels postoperatively. Only 10 patients with known cervical metastatic disease were reoperated upon. We performed extensive node dissection in all. In addition we resected recurrent tumor from the thyroid bed in 4 patients. Despite these extensive reoperations no patient became normocalcitoninemic. At the completion of the study (December 1991), 22 of the 25 patients followed were alive: 4 patients with normal calcitonin levels, baseline and after pentagastrin stimulation, and 18 with persistent mildly elevated calcitonin levels but no other evidence of disease. Our experience supports a very aggressive surgical approach at the time of the first operation for patients with medullary thyroid carcinoma. A lesser operation usually resulted in residual medullary thyroid carcinoma in the neck. We demonstrate the difficulty of achieving a cure by reoperation once the tumor becomes demonstrable by localization studies.

Abstract
Medullary thyroid cancer is a tumor of the thyroid C cells that occurs in sporadic and hereditary clinical settings. Genetic testing of at-risk individuals is available and has been applied to patient management. Plasma calcitonin levels are a very sensitive marker for the presence of disease. Surgery offers the best hope for cure and also is an effective modality for managing metastatic and recurrent disease.

Abstract
The perfect tumor marker would be one that was produced solely by a tumor and secreted in measurable amounts into body fluids, it should be present only in the presence of cancer, it should identify cancer before it has spread beyond a localized site (i.e., be useful in screening), its quantitative amount in bodily fluids should reflect the bulk of tumor, and the level of the marker should reflect responses to treatment and progressive disease. Unfortunately, no such marker currently exists, although a number of useful but imperfect markers are available. The predominant contemporary markers are discussed here by chemical class, as follows: glycoprotein markers, including carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (beta-hCG), and prostate specific antigen (PSA); mucinous glycoproteins, including CA 15-3, CA 19-9, mucinous-like cancer antigen and associated antigens, and CA 125; enzymes, including prostatic acid phosphatase (PAP), neuron specific enolase (NSE), lactic acid dehydrogenase (LDH), and placental alkaline phosphatase (PLAP); hormones and related endocrine molecules, including calcitonin, thyroglobulin, and catecholamines; and, molecules of the immune system, including immunoglobulins and beta-2-microglobulin. The biologic properties of each group of tumor markers are discussed, along with our assessment of their role in clinical medicine today.

Abstract
Fifteen patients with medullary carcinoma of the thyroid (MCT), who had persistently elevated levels of serum calcitonin (CT) and carcinoembryonic antigen (CEA) after total thyroidectomy, were studied in order to localize the sites of the recurrent disease. Routine diagnostic examinations, including ultrasonography (US) and computed axial tomography (CAT), were carried out in all the cases. Scintigraphy with radio-iodinated metaiodobenzylguanidine ((131I)-MIBG) was performed in 13 cases; selective venous catheterization (SVC) to reveal a gradient of CT levels was performed in 12 cases. Ten patients underwent both (131I)-MIBG scintigraphy and SVC. US and CAT revealed the sites of recurrent tumor in only 4 out of the total 15 patients. SVC in basal conditions showed the presence of small metastases in 2 cases, and after intravenous stimulus with pentagastrin in 4 others. The MIBG scan showed metastatic foci of sporadic MCT in 2 patients, residual medullary thyroid tissue in 4 others, and a pheochromocytoma in a previously undiagnosed patient with Sipple's syndrome. More particularly, MIBG scan and SVC showed the localization of residual or metastatic tumor in 10 cases. In all 10 cases, results of the MIBG scan and SVC were confirmed as true positive by subsequent surgery and histopathologic examination.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 20-year-old woman had a sporadic case of medullary thyroid carcinoma (MTC) metastatic to the lungs. After a transient response to streptozotocin and doxorubicin, new subcutaneous lesions appeared on the left chest wall and there was progression of pulmonary disease. Because MTC is one of the amine precursor uptake and decarboxylation (APUD) tumors, treatment was undertaken with agents active in these diseases. Dacarbazine and 5-fluorouracil, given daily for 5 days every 4 weeks, resulted in complete resolution of pulmonary and subcutaneous lesions and a sharp decrease in tumor marker levels that lasted 10 months. Recurrence of the pulmonary disease lead to her death 21 months after presentation. Thus, the chemo-responsiveness of MTC may be akin to that of other APUD carcinomas (APUDomas) and treatment of metastatic MTC and other APUDomas with the combination of dacarbazine and 5-fluorouracil appears to merit further study.

Abstract
Two children with multiple endocrine neoplasia syndrome, Type IIb, (MEN IIb), whose natural mother died from complications of general anesthesia, due to undiagnosed bilateral pheochromocytomas, are described. Of particular interest is the fact that the daughter presented with many stigmata of the syndrome, including the typical facies, while her brother had no obvious clinical manifestations of the syndrome. Both children to date have undergone total thyroidectomy, and pathology reports have confirmed the presence of medullary thyroid carcinoma.

Abstract
Katacalcin (KC) is situated on the C-terminal side of the procalcitonin molecule and is cleaved like calcitonin (CT) from this precursor peptide. Serum levels of KC were measured in 22 patients with C-cell carcinoma with a specific and sensitive radioimmunoassay (normal range, less than 0.1-0.15 ng/ml). Basal serum KC values in C-cell carcinoma patients were 0.32-290 ng/ml. There was a good correlation between KC and CT (r = 0.98, P less than 0.001). Serum KC, as well as CT, markedly increased after pentagastrin and calcium infusion. KC and CT were secreted in nearly equimolar amounts. During selective venous catheterization, KC and CT levels were increased in serum samples from veins draining tumor masses, which could be confirmed operatively. During the follow up, KC and CT measurements correlated well to the stage of disease. KC could be immunohistologically localized in C-cell carcinoma tissue. As a tumor marker, katacalcin is likely to be as useful as calcitonin in C-cell carcinoma.

Abstract
Plasma calcitonin (CT) levels were measured serially in 54 patients surgically treated for medullary thyroid carcinoma. Patients with postoperative basal CT levels higher than 1 ng/ml measured within 1 month after surgery had a higher recurrence rate than those with lower CT levels (p less than 0.002). Patients with postoperative basal CT levels higher than 2 ng/ml had a lower survival rate than those with lower CT levels (p less than 0.01). However, preoperative basal CT levels had no significant correlation with life expectancy or recurrence during the present observation period. Serial measurements in 23 patients with elevated postoperative CT levels showed exponential increases in basal CT levels in 19 patients (p less than 0.05 in nine patients, 0.05 less than p less than 0.1 in four patients) and slight decreases in four (p less than 0.05 in one patient). Doubling time of CT levels calculated from the regression line in each patient showed the highest correlation with 3-year survival, recurrence within 5 years, and time interval between surgery and clinical recurrence of the tumor, allowing quantitative prediction of the prognosis.

Abstract
The multiple endocrine neoplasia (MEN) syndromes are characterized by autosomal dominant inheritance with a high degree of penetrance but varying expression. This review gives a classification of these syndromes and a short summary of the historical background. The pathogenesis of the disease and its possible origin in the APUD cell system are discussed together with the mechanisms underlying normal and ectopic hormone production by MEN tumors on the basis of recent findings in molecular endocrinology. The natural history and the clinical manifestations of the different syndromes are described. The sensitivity and discriminative capacity of the tests used to detect the syndromes in an early stage are compared. The choice of therapy and criteria for the timing and extensiveness of treatment are also considered. Lastly, problems associated with the ethical and legal aspects of screening, central registration, and monitoring of relatives at risk are described.

Abstract
Thirty-one patients were studied to evaluate the prognostic value of both calcitonin (CT) and CEA levels determined after the initial treatment in medullary thyroid carcinoma (MTC). Twenty-seven patients were evaluated three to nine months after initial treatment and four others afterwards. The CT and CEA levels were significantly higher and the survival rate lower in the eight patients with residual clinical disease as compared to the 19 patients in complete clinical remission. In patients in complete clinical remission, 11 had elevated CT level after treatment, and all had initial lymph node involvement. Five of these 11 relapsed and one died. None of the eight patients with normal CT levels after treatment relapsed. CEA levels were always abnormally high when patients relapsed. Fourteen patients in complete remission with high CT levels were followed for more than four years. Six had normal CEA levels and no relapse was observed. Eight of the 14 had pathological CEA levels and six of eight relapsed: five of these six patients presented CEA elevation from six to 36 months before the clinical relapse. In two of these six patients, a venous catheterization sampling method demonstrated infra clinical local recurrence. In two patients with liver metastases, the time course changes of CT and CEA levels were different and CEA appeared to be a more sensitive tumor marker than CT. These data are consistent with previous data concerning the values and limits of CT level for the management of MTC. Furthermore, this study demonstrates the prognostic significance of CEA determination in MTC. CEA appears to be a sensitive selective tumor marker capable of defining a high-risk subgroup.

Abstract
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. It was lower in patients with distant metastases at presentation (p less than 10(-5)), with tumoral infiltration of the posterior tissue planes (p less than 0.025) and in patients in whom surgical excision had not been satisfactory (p less than 0.01). It was not correlated with cervical lymph node involvement probably because those patients with lymph node involvement had been irradiated. The 29 patients who received post-operative cervical radiotherapy had initially more extensive local disease (p less than 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.

Abstract
Many biochemical indices are purported to have clinical utility in the detection and management of neoplasia. Experience gained during the past decade tends to indicate their having a more important role in the detection and monitoring of metastases than of the primary lesion. From this present review of some of the commoner human tumours, it is concluded that such marker substances are important adjuncts in the management of germ cell and certain endocrine and endocrine-related tumours. The carcinoembryonic antigen (CEA) provides a marker for many gastrointestinal cancers, but there are no presently available substances with clinical usefulness for either breast or lung neoplasms. Alternative approaches to the detection of metastases are also presented. The particular use of antibody probes at an immunohistochemical level has been claimed to be able to detect micrometastastic disease in bone marrow or tumour-related monoclonal antibody probes may have application to other cancers in the future.

Abstract
Total thyroidectomy is universally advised for the familial variety of MCT. Although total thyroidectomy is also recommended for sporadic cases, partial thyroidectomy may be adequate. Cervical and upper mediastinal nodes should be sampled for microscopic study, even when they are small and appear to be normal. Appropriate neck or mediastinal nodes should be sampled for microscopic study, even when they are small and appear to be normal. Appropriate neck or mediastinal dissection is done if metastasis is present. External radiation is a valuable adjuvant to surgical excision following the apparent complete resection of the tumor, and is beneficial in the management of unresectable disease. Despite local control, patients continue to die from disseminated disease; therefore, there must be a continued search for an effective chemotherapeutic program. Much remains to be learned from calcitonin monitoring of MCT patients.

Abstract
A family with MEN IIa (medullary thyroid carcinoma (MCT), pheochromocytoma and hyperparathyroidism) was identified. Three relatives had been treated for MCT earlier. Eleven asymptomatic family members had elevated pentagastrin (PG)-stimulated serum immunoreactive calcitonin (i-CT) concentrations, including one who earlier had a pheochromocytoma removed. Nine of these subjects underwent thyroidectomy, and histological examination revealed multifocal MCT in all. Although surgery was judged complete in all, elevated PG-stimulated serum i-CT levels postoperatively indicated residual disease in 5. The natural history of MCTs in the present family varied, with most cases behaving benignly. Occasionally, however, the disease pursued an aggressive course. As MCT often metastasizes before being clinically evident, high cure rates can only be obtained by early diagnosis and treatment, possibly in the pre-metastasizing phase of C-cell hyperplasia, detectable only by elevated PG-stimulated serum i-CT levels.
