    Could the Less-Than Subtotal Parathyroidectomy Be an Option for Treating Young Patients With Multiple Endocrine Neoplasia Type 1-Related Hyperparathyroidism?
    (2019) MONTENEGRO, Fabio Luiz de Menezes; BRESCIA, Manilla D'Elboux Guimaraes; JR, Delmar Muniz Lourenco; ARAP, Sergio Samir; D'ALESSANDRO, Andre Fernandes; SILVA FILHO, Gilberto de Britto e; TOLEDO, Sergio Pereira de Almeida
    Background: The surgical treatment of primary hyperparathyroidism (HPT) in patients with multiple endocrine neoplasia type 1 (MEN1) has evolved due the concern of permanent hypoparathyroidism. As the diagnosis has increased, the extent of operation has decreased. Most MEN1 patients requiring parathyroidectomy are younger than 50 years and they pose a difficult balance to achieve between persistent HPT and life-long hypoparathyroidism. The aim of the present study is to review our experience with a large series of patients with MEN1-related HPT (HPT/MEN1) treated at a single institution in order to find clues to a better treatment decision in these younger cases. Method: Retrospective analysis of consecutive HPT/MEN1 cases treated at a single institution with different operations: total parathyroidectomy and immediate forearm autograft (TPTX-AG), subtotal (STPTX), unintentional less than subtotal (U-LSTPTX) and intentional less than subtotal parathyroidectomy (I-LSTPTX). Results: Considering 84 initial cases operated on since 2011 (TPTX-AG, 39; STPTX, 22, U-LSTPTX, 13, and I-LSTPTX, 10), the rates of hypoparathyroidism were 30.8% (U-LSTPTX), 28.2% (TPTX-AG), 13.6% (STPTX), and 0% (I-LSTPTX). Two-thirds of them (68%; 57/84) were young (< 50 years) or asdolescents. MIBI scan was more sensitive to show parathyroid glands and bilateral disease. Considering the concordance of MIBI and ultrasound for the possibility of unilateral clearance, it would be suitable to 22.6% of the cases. Intra-operative parathormone showed a significant decay even after unilateral exploration, but longer follow up is necessary. Overall, there were seven (4%) adolescents in 161 cases treated from 1987 to 2018, three underwent TPTX-AG and four had U-LSTPTX. Five are euparathyroid, one had mild recurrence, and one required a reoperation after 8 years due to the residual gland. Conclusions: Young patients are the most frequent candidates to parathyroidectomy. Less extensive procedures may be planned only if carefully reviewed preoperative imaging studies suggest a localized disease. Patients and their relatives should be fully informed of the risks and benefits during consent process. Future research with larger cohorts and long-term results are necessary to clarify if less than I-LSPTX or unilateral clearance are really adequate in selected groups of patients with HPT/MEN1 presenting lower volume of disease detected by preoperative imaging studies.

    Multiple endocrine neoplasia type 2 (MEN2) is an autosomal dominant genetic disease caused by RET gene germline mutations that is characterized by medullary thyroid carcinoma (MTC) associated with other endocrine tumors. Several reports have demonstrated that the RET mutation profile may vary according to the geographical area. In this study, we collected clinical and molecular data from 554 patients with surgically confirmed MTC from 176 families with MEN2 in 18 different Brazili an centers to compare the type and prevalence of RET mutations with those from other countries. The most frequent mutations, classified by the number of families affected, occur in codon 634, exon 11 (76 families), followed by codon 918, exon 16 (34 families: 26 with M918T and 8 with M918V) and codon 804, exon 14 (22 families: 15 with V804M and 7 with V804L). When compared with other major published series from Europe, there are several similarities and some differences. While the mutations in codons C618, C620, C630, E768 and S891 present a similar prevalence, some mutations have a lower prevalence in Brazil, and others are found mainly in Brazil (G533C and M918V). These results reflect the singular proportion of European, Amerindian and African ancestries in the Brazilian mosaic genome.

    Penetrance of Functioning and Nonfunctioning Pancreatic Neuroendocrine Tumors in Multiple Endocrine Neoplasia Type 1 in the Second Decade of Life
    (2014) GONCALVES, Tatiana D.; TOLEDO, Rodrigo A.; SEKIYA, Tomoko; MATUGUMA, Sergio E.; MALUF FILHO, Fauze; ROCHA, Manoel S.; SIQUEIRA, Sheila A. C.; GLEZER, Andrea; BRONSTEIN, Marcelo D.; PEREIRA, Maria A. A.; JUREIDINI, Ricardo; BACCHELLA, Telesforo; MACHADO, Marcel C. C.; TOLEDO, Sergio P. A.; LOURENCO JR., Delmar M.
    Context: Data are scarce on the penetrance of multiple endocrine neoplasia type 1 (MEN1)-related nonfunctioning pancreatic neuroendocrine tumors (NF-PETs) and insulinomas in young MEN1 patients. Apotential positive correlation between tumor size and malignancy (2-3 cm, 18%; >3 cm, 43%) has greatly influenced the management of MEN1 adults with NF-PETs. Objective: The aim of the study was to estimate the penetrance of NF-PETs, insulinomas, and gastrinomas in young MEN1 carriers. Design: The data were obtained from a screening program (1996-2012) involving 113 MEN1 patients in a tertiary academic reference center. Patients: Nineteen MEN1 patients (aged 12-20 y; 16 patients aged 15-20 y and 3 patients aged 12-14 y) were screened for NF-PETs, insulinomas, and gastrinomas. Methods: Magnetic resonance imaging/computed tomography and endoscopic ultrasound (EUS) were performed on 10 MEN1 carriers, magnetic resonance imaging/computed tomography was performed on five patients, and four other patients underwent an EUS. Results: The overall penetrance of PETs during the second decade of life was42%(8 of 19). All eight PET patients had NF-PETs, and half of those tumors were multicentric. One-fifth of the screened patients (21%; 4 of 19) harbored at least one large tumor (>2.0 cm). Insulinoma was detected in two NF-PET patients (11%) at the initial screening; gastrinoma was not present in any cases. Six of the 11 (54%) screened patients aged 15-20 years who underwent an EUS had NF-PETs. Potential false-positive EUS results were excluded based on EUS-guided biopsy results, the reproducibility of the NF-PET findings, or the observation of increased tumor size during follow-up. Distal pancreatectomy and the nodule enucleation of pancreatic head tumors were conducted on three patients with large tumors (>2.0 cm; T2N0M0) that were classified as grade 1 neuroendocrine tumors (Ki-67 < 2%). Conclusions: Our data demonstrated high penetrance of NF-PETs in 15- to 20-year-old MEN1 patients. The high percentage of the patients presenting consensus criteria for surgery for NF-PET alone or NF-PET/insulinoma suggests a potential benefit for the periodic surveillance of these tumors in this age group.

    Germline mutation landscape of multiple endocrine neoplasia type 1 using full gene next-generation sequencing
    (2018) CARVALHO, Rafael A.; URTREMARI, Betsaida; JORGE, Alexander A. L.; SANTANA, Lucas S.; QUEDAS, Elisangela P. S.; SEKIYA, Tomoko; LONGUINI, Viviane C.; MONTENEGRO, Fabio L. M.; LERARIO, Antonio M.; TOLEDO, Sergio P. A.; MARX, Stephen J.; TOLEDO, Rodrigo A.; JR, Delmar M. Lourenco
    Background: Loss-of-function germline MEN1 gene mutations account for 75-95% of patients with multiple endocrine neoplasia type 1 (MEN1). It has been postulated that mutations in non-coding regions of MEN1 might occur in some of the remaining patients; however, this hypothesis has not yet been fully investigated. Objective: To sequence for the entire MEN1 including promoter, exons and introns in a large MEN1 cohort and determine the mutation profile. Methods and patients: A target next-generation sequencing (tNGS) assay comprising 7.2 kb of the full MEN1 was developed to investigate germline mutations in 76 unrelated MEN1 probands (49 familial, 27 sporadic). tNGS results were validated by Sanger sequencing (SS), and multiplex ligation-dependent probe amplification (MLPA) assay was applied when no mutations were identifiable by both tNGS and SS. Results: Germline MEN1 variants were verified in coding region and splicing sites of 57/76 patients (74%) by both tNGS and SS (100% reproducibility). Thirty-eight different pathogenic or likely pathogenic variants were identified, including 13 new and six recurrent variants. Three large deletions were detected by MLPA only. No mutation was detected in 16 patients. In untranslated, regulatory or in deep intronic MEN1 regions of the 76 MEN1 cases, no point or short indel pathogenic variants were found in untranslated, although 33 benign/likely benign and three new VUS variants were detected. Conclusions: Our study documents that point or short indel mutations in non-coding regions of MEN1 are very rare events. Also, tNGS proved to be a highly effective technology for routine genetic MEN1 testing.

    Successful parathyroid tissue autograft after 3 years of cryopreservation: a case report
    (2014) LEITE, Ana K. N.; JUNIOR, Climerio P. do N.; ARAP, Sergio S.; MASSONI, Ledo; LOURENCO, Delmar M.; BRANDAO, Lenine Garcia; MONTENEGRO, Fabio L. de M.
    After a total parathyroidectomy, well-established protocols for the cryopreservation of parathyroid tissue and for the delayed autograft of this tissue exist, especially in cases of secondary hiperparathyroidism (HPT) or familial or sporadic parathyroid hyperplasia. Although delayed autografts are effective, the published success rates vary from 10% to 83%. There are numerous factors that influence the viability, and therefore the success, of an autograft, including cryopreservation time. Certain authors believe that the tissue is only viable for 24 months, but there is no consensus on how long the parathyroid tissue can be preserved. A 63-year-old male who was diagnosed with sporadic multiple endocrine neoplasia type 1 and primary hyperparathyroidism, and was submitted to a total parathyroidectomy and an autograft in the forearm. The implant failed, and the patient developed severe hypoparathyroidism in the months following the surgery. Thirty-six months after the total parathyroidectomy, the cryopreserved autograft was successfully transplanted, and hypoparathyroidism was reversed (most recent systemic parathyroid hormone, PTH, of 36 pg/mL, and total calcium of 9.1 mg/dL; no oral calcium supplementation). The case presented here indicates that cryopreserved parathyroid tissue may remain viable after 24 months in storage, and may retain the capacity to reverse permanent postsurgical hypoparathyroidism. These data provide reasonable evidence that the time limit for cryopreservation remains undetermined and that additional research would be valuable.

    Assessment of Depression, Anxiety, Quality of Life, and Coping in Long-Standing Multiple Endocrine Neoplasia Type 2 Patients
    (2017) RODRIGUES, Karine C.; TOLEDO, Rodrigo A.; COUTINHO, Flavia L.; NUNES, Adriana B.; MACIEL, Rui M. B.; HOFF, Ana O.; TAVARES, Marcos C.; TOLEDO, Sergio P. A.; LOURENCO JR., Delmar M.
    Background: Data on psychological harm in multiple endocrine neoplasia type 2 (MEN2) are scarce. Objectives: The aim of this study was to assess anxiety, depression, quality of life, and coping in long-standing MEN2 patients. Patients and Methods: Patients were 43 adults (age >= 18 years) with clinical and genetic diagnosis of MEN2 and long-term follow-up (10.6 +/- 8.2 years; range 1-33 years). This was a cross-sectional study with qualitative and quantitative psychological assessment using semi-directed interviews and HADS, EORTC QLQ C30, and MINI-MAC scales. Adopting clinical criteria from 2015 ATA Guidelines on MEN2, biochemical cure (39%; 16/41), persistence/recurrence (61%; 25/41), and stable chronic disease (22/41) of medullary thyroid carcinoma (MTC) were scored. Pheochromocytoma affected 19 (44%) patients, with previous adrenalectomy in 17 of them. Results: Overall, anxiety (42%; mean score 11 +/- 2.9; range 8-18; anxiety is defined as a score >= 8) and depression (26%; mean score 11 +/- 3.8; range 8-20; depression is defined as a score >= 8) symptoms were frequent. Patients who transmitted RET mutations to a child had higher scores for weakness-discouragement/anxious preoccupation and lower scores for cognitive, emotional, and physical functioning (p < 0.05). Feelings of guilt were present in 35% of patients with mutation-positive children. Lower mean score values for depression and anxiety and higher scores for role, cognitive, and emotional functioning were noticed in 33 patients who were well-informed about their disease (p < 0.05). Fighting spirit was more frequently found in patients with multiple surgical procedures (p = 0.019) and controlled chronic adrenal insufficiency (p = 0.024). Patients with MEN2-elated stress-inducing factors had lower scores for fighting spirit and cognitive functioning and higher scores for insomnia and dyspnea (p < 0.05). Eleven patients required sustained psychotherapeutic treatment. Mean global health status was relatively good in MEN2 cases (68.1 +/- 22.3), and the cured group had higher physical functioning (p = 0.021). Conclusions: Psychological distress is likely chronic in MEN2 patients. This study identified diverse MEN2-related factors (degree of information on disease, mutation-positive children, number of surgeries, comorbidities, stress-inducing factors, and cure) interfering positively or negatively with the results of the psychometrics scales. The active investigation of these factors and the applied psychological assessment protocol are useful to identify MEN2 patients requiring psychological assistance.

    Natural history, treatment, and long-term follow up of patients with multiple endocrine neoplasia type 2B: an international, multicentre, retrospective study
    (2019) CASTINETTI, Frederic; WAGUESPACK, Steven G.; MACHENS, Andreas; UCHINO, Shinya; HASSE-LAZAR, Kornelia; SANSO, Gabriella; ELSE, Tobias; DVORAKOVA, Sarka; QI, Xiao Ping; ELISEI, Rossella; MAIA, Ana Luisa; GLOD, John; LOURENCO JR., Delmar Muniz; VALDES, Nuria; MATHIESEN, Jes; WOHLLK, Nelson; BANDGAR, Tushar R.; DRUI, Delphine; KORBONITS, Marta; DRUCE, Maralyn R.; BRAIN, Caroline; KURZAWINSKI, Tom; PATOCS, Atila; BUGALHO, Maria Joao; LACROIX, Andre; CARON, Philippe; FAINSTEIN-DAY, Patricia; CHAZOT, Francoise Borson; KLEIN, Marc; LINKS, Thera P.; LETIZIA, Claudio; FUGAZZOLA, Laura; CHABRE, Olivier; CANU, Letizia; COHEN, Regis; TABARIN, Antoine; UROIC, Anita Spehar; MAITER, Dominique; LABOUREAU, Sandrine; MIAN, Caterina; PECZKOWSKA, Mariola; SEBAG, Frederic; BRUE, Thierry; MIREBEAU-PRUNIER, Delphine; LECLERC, Laurence; BAUSCH, Birke; BERDELOU, Amandine; SUKURAI, Akihiro; VLCEK, Petr; KRAJEWSKA, Jolanta; BARONTINI, Marta; VARGAS, Carla Vaz Ferreira; VALERIO, Laura; CEOLIN, Lucieli; AKSHINTALA, Srivandana; HOFF, Ana; GODBALLE, Christian; JARZAB, Barbara; JIMENEZ, Camilo; ENG, Charis; IMAI, Tsuneo; SCHLUMBERGER, Martin; GRUBBS, Elizabeth; DRALLE, Henning; NEUMANN, Hartmut P.; BAUDIN, Eric
    Background Multiple endocrine neoplasia type 2B is a rare syndrome caused mainly by Met918Thr germline RET mutation, and characterised by medullary thyroid carcinoma, phaeochromocytoma, and extra-endocrine features. Data are scarce on the natural history of multiple endocrine neoplasia type 2B. We aimed to advance understanding of the phenotype and natural history of multiple endocrine neoplasia type 2B, to increase awareness and improve detection. Methods This study was a retrospective, multicentre, international study in patients carrying the Met918Thr RET variant with no age restrictions. The study was done with registry data from 48 centres globally. Data from patients followed-up from 1970 to 2016 were retrieved from May 1, 2016, to May 31, 2018. Our primary objectives were to determine overall survival, and medullary thyroid carcinoma-specific survival based on whether the patient had undergone early thyroidectomy before the age of 1 year. We also assessed remission of medullary thyroid carcinoma, incidence and treatment of phaeochromocytoma, and the penetrance of extra-endocrine features. Findings 345 patients were included, of whom 338 (98%) had a thyroidectomy. 71 patients (21%) of the total cohort died at a median age of 25 years (range <1-59). Thyroidectomy was done before the age of 1 year in 20 patients, which led to long-term remission (ie, undetectable calcitonin level) in 15 (83%) of 18 individuals (2 patients died of causes unrelated to medullary thyroid carcinoma). Medullary thyroid carcinoma-specific survival curves did not show any significant difference between patients who had thyroidectomy before or after 1 year (comparison of survival curves by log-rank test: p=0.2; hazard ratio 0.35; 95% CI 0.07-1.74). However, there was a significant difference in remission status between patients who underwent thyroidectomy before and after the age of 1 year (p<0.0001). There was a significant difference in remission status between patients who underwent thyroidectomy before and after the age of 1 year (p<0.0001). In the other 318 patients who underwent thyroidectomy after 1 year of age, biochemical and structural remission was obtained in 47 (15%) of 318 individuals. Bilateral phaeochromocytoma was diagnosed in 156 (50%) of 313 patients by 28 years of age. Adrenal-sparing surgery was done in 31 patients: three (10%) of 31 patients had long-term recurrence, while normal adrenal function was obtained in 16 (62%) patients. All patients with available data (n=287) had at least one extra-endocrine feature, including 106 (56%) of 190 patients showing marfanoid body habitus, mucosal neuromas, and gastrointestinal signs. Interpretation Thyroidectomy done at no later than 1 year of age is associated with a high probability of cure. The reality is that the majority of children with the syndrome will be diagnosed after this recommended age. Adrenal-sparing surgery is feasible in multiple endocrine neoplasia type 2B and affords a good chance for normal adrenal function. To improve the prognosis of such patients, it is imperative that every health-care provider be aware of the extra-endocrine signs and the natural history of this rare syndrome. The implications of this research include increasing awareness of the extra-endocrine symptoms and also recommendations for thyroidectomy before the age of 1 year.

    Complete Resolution of Hypercortisolism with Sorafenib in a Patient with Advanced Medullary Thyroid Carcinoma and Ectopic ACTH (Adrenocorticotropic Hormone) Syndrome
    (2014) BARROSO-SOUSA, Romualdo; LERARIO, Antonio Marcondes; EVANGELISTA, Joao; PAPADIA, Carla; LOURENCO JR., Delmar M.; LIN, Chin Shien; KULCSAR, Marco Antonio; FRAGOSO, Maria Candida; HOFF, Ana O.
    Background: The treatment of advanced medullary thyroid carcinoma (MTC) has evolved significantly over the past decade. The discovery of genetic abnormalities in MTC has led to the development of targeted therapies such as vandetanib and cabozantinib. Other kinase inhibitors (KI), such as sorafenib, have been investigated in this setting and are an alternative therapeutic option. The lack of specificity of these KIs to a single target may result in additional, unexpected effects. In this report, we describe a patient with metastatic MTC and Ectopic ACTH (adrenocorticotropic hormone) Syndrome in whom treatment with sorafenib resulted in complete resolution of hypercortisolism. Summary: A 45-year-old male with progressive metastatic MTC presented with clinical manifestations suspicious for Cushing's syndrome. Investigation revealed ACTH-dependent hypercortisolism suggestive of Ectopic ACTH Syndrome. Treatment with sorafenib 400 mg twice a day was initiated resulting in a rapid and significant reduction of cortisol and ACTH levels associated with dramatic clinical improvement. The rapid and effective control of hypercortisolism in the absence of a significant tumor reduction raises the question of whether sorafenib may have a direct effect on ACTH or cortisol hypersecretion. Conclusions: This report suggests a previously unknown potential effect of sorafenib on the pituitary-adrenal axis. Further studies will be necessary to investigate the role of sorafenib in other cases of ACTH excess and to understand the mechanisms by which it alters steroid synthesis, action, or secretion.

    Glucose-dependent insulinotropic peptide receptor overexpression in adrenocortical hyperplasia in MEN1 syndrome without loss of heterozygosity at the 11q13 locus
    (2011) COSTA, Marcia Helena Soares; DOMENICE, Sorahia; TOLEDO, Rodrigo Almeida; JUNIOR, Delmar Muniz L.; LATRONICO, Ana Claudia; PINTO, Emilia Modolo; TOLEDO, Sergio Pereira Almeida; MENDONCA, Berenice Bilharinho; FRAGOSO, Maria Candida Barisson Villares
    BACKGROUND: The molecular mechanisms involved in the genesis of the adrenocortical lesions seen in MEN1 syndrome (ACL-MEN1) remain poorly understood; loss of heterozygosity at 11q13 and somatic mutations of MEN1 are not usually found in these lesions. Thus, additional genes must be involved in MEN1 adrenocortical disorders. Overexpression of the glucose-dependent insulinotropic peptide receptor has been shown to promote adrenocortical tumorigenesis in a mice model and has also been associated with ACTH-independent Cushing syndrome in humans. However, to our knowledge, the status of glucose-dependent insulinotropic peptide receptor expression in adrenocortical lesions in MEN1 has not been previously investigated. OBJECTIVE: To evaluate glucose-dependent insulinotropic peptide receptor expression in adrenocortical hyperplasia associated with MEN1 syndrome. MATERIALS/METHODS: Three adrenocortical tissue samples were obtained from patients with previously known MEN1 germline mutations and in whom the presence of a second molecular event (a new MEN1 somatic mutation or an 11q13 loss of heterozygosity) had been excluded. The expression of the glucose-dependent insulinotropic peptide receptor was quantified by qPCR using the Delta Delta CT method, and beta-actin was used as an endogenous control. RESULTS: The median of glucose-dependent insulinotropic peptide receptor expression in the adrenocortical lesions associated with MEN1 syndrome was 2.6-fold (range 1.2 to 4.8) higher than the normal adrenal controls (p = 0.02). CONCLUSION: The current study represents the first investigation of glucose-dependent insulinotropic peptide receptor expression in adrenocortical lesions without 11q13 loss of heterozygosity in MEN1 syndrome patients. Although we studied a limited number of cases of MEN1 adrenocortical lesions retrospectively, our preliminary data suggest an involvement of glucose-dependent insulinotropic peptide receptor overexpression in the etiology of adrenocortical hyperplasia. New prospective studies will be able to clarify the exact role of the glucose-dependent insulinotropic peptide receptor in the molecular pathogenesis of MEN1 adrenocortical lesions.

    Quality of Life and Coping in Multiple Endocrine Neoplasia Type 2
    (2019) CORREA, Fernanda A.; FARIAS, Evelin C.; CASTRONEVES, Luciana A.; LOURENCO JR., Delmar M.; HOFF, Ana O.
    Scarce data are available on the quality of life and psychosocial distress of patients with multiple endocrine neoplasia type 2 (MEN2), a genetic cancer syndrome caused by RET germline mutations. Carriers of RET mutations can face several challenges, including fear for the future, guilt for transmission of a germline mutation to an offspring, side effects of cancer treatment, coping behaviors in the face of a chronic and frequently incurable cancer, and difficulties in access to adequate health care. We have addressed the effects of genetic testing on the quality of life of patients with MEN2 and the lifelong physical and psychosocial challenges experienced by these patients. We have also suggested strategies to minimize the burden of living with this chronic condition and the perspectives on future studies to improve the health-related quality of life of the patients.
