Hereditary medullary thyroid carcinoma (MTC) appears in three forms: 1) in association with pheochromocytomas and parathyroid hyperplasia (multiple endocrine neoplasia type 2 A [MEN 2A]); 2) with pheochromocytomas, neuromas of the mucous membranes, and a marfanoid appearance (MEN 2B): and 3) without pheochromocytoma. Despite these differences in presentation, age of onset, and clinical severity, limited genetic studies suggest that the three MTC variants may be due to inherited mutations at the same gene locus. We present further data in support of the hypothesis that allelic variation may underlie the diversity of these endocrine neoplasia syndromes.

The multiple endocrine neoplasia type 2A (MEN 2A) gene has been mapped to the centromeric region of chromosome 10 by linkage analysis. We examined 36 medullary thyroid carcinomas (MTCs) (16 hereditary and 20 sporadic) and ten pheochromocytomas (eight hereditary and two sporadic) to detect loss of alleles on chromosome 10 using seven polymorphic DNA markers mapped to this chromosome. Of 20 informative cases, only one (5%) sporadic MTC showed loss of heterozygosity at the locus RBP3. Allele loss at the RBP3 locus was not found in pheochromocytomas from six heterozy gates. All tumors retained constitutional heterozygosity at six other loci …

Family .screening for medullary thyroid cancer (MTC) is important for detecting members of multiple endocrine neoplasia type 2 (MEN 2) families who may be gene carriers but show no clinical evidence of the disease. Most members of our MEN 2 families are screened yearly by measuring basal and pentagastrin-stimulated calcitonin (CT) levels. A 15-year-old first-degree relative of an affected member of the D-kindred showed a normal basal and an elevated stimulated CT level. Clinical examination, ultrasonography, and scintigraphy were normal. Thyroidectomy and bilateral neck dissection revealed a multicentric MTC with no lymph node involvement. In the O-kindred we detected elevated …

Men 2a: Update On The Northern Ireland And Australian Family, Patrick J. Morrison, David R. Hadden, Colin J. Russell, Norman C. Nevin
Henry Ford Hospital Medical Journal
The Northern Ireland/Australian family with multiple endocrine neoplasia type 2A (MEN 2A) originally described in 1987 is presented with a revised and enlarged pedigree. Four members of the first generation studied have died. A seventh member of the second generation studied has developed medullary thyroid carcinoma and has progressed to surgery. None of the third generation members studied has shown any conclusive abnormality in metabolic screening tests. Each member of the third and fourth generations has had genetic counseling and (if appropriate) DNA analysis with gene probes close to the MEN 2A gene locus on chromosome 10. All members of …

Henry Ford Hospital Medical Journal
A Japanese family of 87 members in five generations with multiple endocrine neoplasia type 2A (MEN 2A) is described regarding the utility of screening tests for early detection of medullary thyroid carcinoma and the potential for DNA diagnosis of MEN 2A gene carriers. The screening programs for family members in this series include measurements of plasma calcitonin concentrations after intravenous injection of pentagastrin (0.5 μg/kg/5 sec) and 24-hour urinary excretion of catecholamines. While 18 MEN 2A patients had been previously diagnosed, these screening programs revealed five additional patients with MEN 2A (aged 16, 19, 35, 37, and 57). Prediction of …

Between 1960 and 1988, 185 patients with medullary thyroid carcinoma (MTC) were followed at the Institut Gustave Roussy in France. The screening of the family members by calcitonin measurement (basal or after pentagastrin stimulation) has led lo the characterization of 38 sporadic cases and 44 hereditary cases. Among the hereditary cases are seven families with MTC only and two families with multiple endocrine neoplasia type 2A (MEN 2A). MTC only cases and MEN 2B cases are present as apparently sporadic forms. Hereditary cases consisted of 26 females and 18 males; the male-female ratio was 21:17 in sporadic cases. Ten of …

We have previously described a kindred with hereditary medullary thyroid carcinoma and pheochromocytoma (multiple endocrine neoplasia type 2 A [MEN 2A]) with localized pruritic cutaneous manifestations present only in affected members. Although the initial skin biopsies reported did not show amyloidosis, subsequent skin biopsy results reported here have demonstrated amyloid which stained for keratin but not for calcitonin and established that this family represents an association of a rare autosomal dominant form of lichen amyloidosis with MEN 2A.

Henry Ford Hospital Medical Journal
Patients with palpable medullary thyroid carcinoma (MTC) have lymph node metastases in 90% of cases. In most series such patients continue to have elevated serum calcitonin (CT) levels after surgery indicating residual tumor tissue. We attempted a microdissection technique for the treatment of MTC. ' 'Micro'' refers not to a small incision or a limited exploration but to a more safe operation associated with good lighting and magnification and minimal bleeding. This technique was used in a 13-year-old girl with multiple endocrine neoplasia type 2B (MEN 2B). The prognosis for MTC in MEN 2B is worse than for sporadic MTC …

Henry Ford Hospital Medical Journal
An experimental animal model with adrenal cortex transplantation was developed to study adrenal cortex replacement therapy in patients with multiple endocrine neoplasia type 2 who have had bilateral adrenalectomy for pheochromocytomas. Adrenal cortex of syngenetic rats was isolated from the medulla by collagenase digestion and a defined sedimentation. The cell suspension of the cortical cells was implanted under the kidney capsule of untreated syngenetic rats. After two weeks the recipients were bilaterally adrenalectomized. Serum corticosterone levels were measured as an estimate of function of the grafts. All recipients were healthy throughout the observation period, whereas all adrenalectomized controls died within …

Henry Ford Hospital Medical Journal
Pheochromocytoma is a major cause of morbidity and mortality in the multiple endocrine neoplasia type 2 (MEN 2) syndrome. For the physician, surgical treatment seems well justified even though bilateral adrenalectomy will induce iatrogenically complete loss of adrenocortical function. For the patient this treatment may be a cause of medical problems as well as worry. We have evaluated quality of life after bilateral adrenalectomy in 27 MEN 2 patients through a combined oral and written approach. Mortality was low (one of 27), as was serious morbidity. Most patients had adapted well to the postadrenalectomy state. However, fatigue, worry, and noncompliance …

Unlike the purely medical research done in multiple endocrine neoplasia type 2 (MEN 2) families, little work has been done on the psychosocial aspects of the disease. To assess the severely stressful influences and the consequences of that stress on the family network, a small-scale survey was carried out during a national meeting. The goal of the study was to obtain more information about the experiences and needs of MEN 2 patients and their relatives. Of the 59 respondents, 85% were satisfied with the medical information provided, 81% were satisfied with the medical knowledge of the specialist, but only 12% …

Henry Ford Hospital Medical Journal
99mTc (V) dimercaptosuccinic acid (DMSA) is a new tumor imaging agent that has been successfully used to image patients with medullary thyroid carcinoma (MTC). Since 1986, studies have been performed in 32 patients with histologically proven MTC at Guy's Hospital, London, England. Five patients with primary tumor were studied prior lo surgery, four patients were studied after successful removal of the primary tumor, and 26 patients with biochemical evidence of recurrence were studied. Eight patients were studied serially to assess progression of disease, and four patients were studied before and after surgery. Twenty-one of the 26 patients with disease had …

We compared three differenl scintigraphic techniques for the localization of neck recurrences and metastases in seven patients wiih medullary thyroid carcinoma one month to eight years after the first surgical intervention. Three successive scintigraphic studies were performed in five patients (6x3 studies) within two weeks using 201Tl chloride, 111In-labeled F(ab')2 fragments of the anticarcinoembryonic antigen (anti-CEA) monoclonal antibody (MoAb) BW 431/31. and 131I meta-iodobenzylguanidine (MIBG). Additionally, 11 studies were performed wilh the 111In-labeled MoAb fragment BW 431/31 (seven studies) or the 99mTc-labeled intact anti-CEA MoAb BW 431/26 (four studies). The gold standards for classifying scintigraphic results were biopsy, histology, surgery, …

The diagnostic value of 123/131I meta-iodo-benzylguanidine (MIBG) and 99mTc (V) dimercaptosuccinic acid (DMSA) was investigated in 12 patients with proven medullary thyroid carcinoma (MTC). Scintigraphic imaging with DMSA was negalive in nine of 12 patients. Scintigraphy with MIBG was positive in only one case. In proven primary or recurrent disease, DMSA sensitivity was 50% and MIBG sensitivity was 25%. Such sensitivities become much lower in subjects wilh high calcitonin (CT) levels who have had negative surgical explorations: DMSA 17% and MIBG 0%. DMSA delected tumor in 25% of the patients and MIBG in only 8%. The positivity of these scintigraphies …

Recently developed radiopharmaceuticals have been proposed for imaging medullary thyroid carcinoma (MTC) with some having therapeutic potential. This study compares the imaging results obtained with radioiodinated meta-iodo-benzylguanidine (MIBG), 99mTc (V) DMSA, and 131I F(ab')2 anti-carcinoembryonic antigen (anti-CEA) in a group of MTC patients. In 23 patients 131I MIBG imaging showed a high specificity (no false-positive results) but a less satisfactory sensitivity (50%). In 12 patients 99mTc (V) DMSA revealed a better sensitivity (77%) but a lower specificity (three false-positive results). Positive results were obtained in two of three patients studied with 131I F(ab')2 anti-CEA. These data suggest that the highly …

Immunoreactive calcitonin (ICT) can be ectopically secreted by lung cancer cells and has been proposed as a tumor marker for bronchial neoplasms. Since PDN-21 (katacalcin or the carboxyl-terminal flanking peptide of the calcitonin gene) and CT are cosecreted in normal subjects and in patients with medullary thyroid carcinoma (MTC), we sought to determine the potential utility of PDN-21 as a tumor marker for lung cancer. We measured carcinoembryonic antigen (CEA), neuronspecific enolase (NSE), iCT, and PDN-21 in 119 to 378 healthy subjects, 88 to 91 patients with benign pulmonary diseases, and 249 patients with advanced lung cancer (108 small cell …

Recombinant DNA techniques have made it possible to establish the structure of various genes encoding polypeptide hormones. Comparison of nucleotide sequences of the calcitonin (CALC) genes in man has revealed surprising similarities and variations. These findings and the homologies among the sequences in different species offered an opportunity for speculation about relationships between these genes and about their evolutionary origin. The first gene (CALC-I) directing the synthesis of calcitonin (CT) or CT gene-related peptide (CGRP) comprises six exons and gives rise to two mRNAs by an alternative RNA-processing mechanism. The homology between CGRP and CT reflects their common origin. The …

A Novel Parathyroid Hormone-Related Gene Product, T. J. Martin, J. A. Danks
Henry Ford Hospital Medical Journal
A parathyroid hormone-related protein (PTHrP) has been invoked as being responsible for the humoral hypercalcemia of malignancy. Eight of the first 13 amino acids of PTHrP are identical with those in PTH, but there is no other significant homology. The PTHrP gene is located on chromosome 12, whereas that for PTH is on chromosome 11, and the two genes are probably related by a duplication process. Antisera against PTHrP(1-34), which cross-read poorly or not at all with PTH, and antisera against other parts of PTHrP not homologous to PTH were used in immunocytochemistry, using a peroxidase-antiperoxidase method, to identify PTHrP …

We have applied DNA transfer techniques lo study the transcriptional regulation of the calcitonin (CT) gene in a C-cell line (TT) derived from a human medullary thyroid carcinoma. TT cells were transfected with a fusion gene containing the CT gene promoter and 5' -flanking DNA attached to the promoter-less growth hormone gene (reporter). We quantitated the reporter gene product to monitor transcriptional activation by the CT promoter and deletion mutants of the 5' -flanking DNA. We found that the proximal CT promoter which includes the DNA sequence from +1 to -129 bp upstream from the CT transcription start site did …

Closing In On The Men2a Locus, Nancy E. Simpson, Kenneth K. Kidd
Henry Ford Hospital Medical Journal
The mapping of the locus for multiple endocrine neoplasia type 2A (MEN 2A) to chromosome 10 using linkage is briefly reviewed including a discussion of linkage strategy and reference to some of the exclusions before the assignment. The subsequent development of the map of the centromeric region of the chromosome and the linking of what appear to be the four closest flanking markers and the centromeric alphoid sequence to the disease locus are reviewed. To date no recombination has been observed between the centromeric marker and the MEN2A locus among, at least, 26 informative meioses, 11 of which are phase …

Henry Ford Hospital Medical Journal
Screening for medullary thyroid cancer (MTC) in France is based on a protocol that has been widely distributed nationally. A network of coordinators utilizing a common questionnaire provides for an effective national screening program. Calcitonin stimulation procedures are systematically used for all first-degree relatives of MTC patients. Pathological studies utilize special immunopathologic techniques. Genealogic information is obtained on all index cases, and blood specimens are collected for establishing permanent cell lines. The data collected are used not only to establish the diagnosis of the hereditary or sporadic form of the disease but also to expand the screening as appropriate. This …

Henry Ford Hospital Medical Journal
Twenty-two patients with the multiple endocrine neoplasia type 2 (MEN 2) syndrome were screened for pheochromocytoma since it is a major cause of morbidity in MEN 2 families. Clinical symptoms, biochemical parameters, ultrasound, computed tomography or magnetic resonance imaging, and meta-iodo-benzylguanidine (MIBG) scintigraphy were evaluated for detection of adrenal tumors. Clinical symptoms and plasma or urine catecholamines appeared to be nonspecific, whereas MIBG scintigraphy was highly specific and the most sensitive parameter. Patients older than age 30 should be scintigraphically screened at least once despite the radiation exposure. Demonstration of only slight uptake is not an indication for surgery but …

Postoperative Pentagastrin-Stimulated Serum Calcitonin Concentrations In Patients With Medullary Thyroid Carcinoma: Reoperations In Patients With Concentrations Bordering The Detection Limit, Hinrich Meybier, Heinrich Schmidt-Gayk, Heinz Buhr, Friedhelm Raue
Henry Ford Hospital Medical Journal
The case reports on two patients with medullary thyroid carcinoma show that even postoperatively stimulated serum calcitonin (CT) concentrations near the detection limit (using a polyclonal antibody against synthetic CT) can demonstrate persistent disease. Stimulated CT concentrations can be lowered to nondetectable levels by a second and third operation if a meticulous technique is used for dissection of the lymph compartments. The patient can then be assumed lo be cured. Diagnostic accuracy at very low CT concentrations can be improved by selective venous catheterization with blood sampling for CT after stimulation.

Henry Ford Hospital Medical Journal
Multiple endocrine neoplasia type 2A (MEN 2A) is a rare hereditary disease transmitted in families as an autosomal dominant trad. We have identified a family in which the expression of a rare autosomal dominant form of cutaneous lichen amyloidosis appears to cosegregate with MEN 2A. In this family the skin lesion presented as multiple infiltrated papules overlying well demarcated plaques over the scapular area (right or left). Immunohistochemical studies demonstrated amyloid which stained for keratin but not calcitonin. A total of 19 members were screened. Three members of the family have the characteristic skin lesion and MEN 2A; two additional …

We have studied seven subjects with medullary thyroid carcinoma. Each had elevated basal serum calcitonin (CT) levels following total thyroidectomy. After subcutaneous administration of 100 μg of SMS 201-995, blood samples were collected at 60-minute intervals for six hours. Two patients showed a marked decrease of CT levels (patient A: baseline 565 μg/mL, nadir 150 μg/mL; patient B: baseline 1,632 μg/mL, nadir 416 μg/mL). The other five patients showed no significant change in comparison with saline infusion. Two patients were treated with SMS 201-995 (300 μg/day)for 90 days. One of these patients responded to the acute SMS 201-995 test and …
