Abstract
Thyroid nodules are common findings, particularly in iodine-deficient regions. Our paper aims to revise different diagnostic tools available in clinical thyroidology and propose their rational integration. We will elaborate on the pros and cons of thyroid ultrasound (US) and its scoring systems, thyroid scintigraphy, fine-needle aspiration cytology (FNAC), molecular imaging, and artificial intelligence (AI). Ultrasonographic scoring systems can help differentiate between benign and malignant nodules. Depending on the constellation or number of suspicious ultrasound features, a FNAC is recommended. However, hyperfunctioning thyroid nodules are presumed to exclude malignancy with a very high negative predictive value (NPV). Particularly in regions where iodine supply is low, most hyperfunctioning thyroid nodules are seen in patients with normal thyroid-stimulating hormone (TSH) levels. Thyroid scintigraphy is essential for the detection of these nodules. Among non-toxic thyroid nodules, a careful application of US risk stratification systems is pivotal to exclude inappropriate FNAC and guide the procedure on suspicious ones. However, almost one-third of cytology examinations are rendered as indeterminate, requiring "diagnostic surgery" to provide a definitive diagnosis. 99mTc-methoxy-isobutyl-isonitrile ([99mTc]Tc-MIBI) and [18F]fluoro-deoxy-glucose ([18F]FDG) molecular imaging can spare those patients from unnecessary surgeries. The clinical value of AI in the evaluation of thyroid nodules needs to be determined.

Abstract
BACKGROUND Familial non-medullary thyroid cancer (NMTC) occurs either as part of known hereditary syndromes or as a non-syndromic isolated hereditary tumor. Although the genes underlying the syndromic type of NMTC have been identified in most syndromes, no clear underlying gene has been identified in the non-syndromic NMTC. Recently, a c.1601G>A, p.G534E mutation in the HABP2 gene was reported to be the underlying genetic defect in a family with seven members affected by NMTC. The G534E variant has also been reported to occur in about 4.7% of cases of the Thyroid Cancer Genome Atlas (TCGA) database. OBJECTIVES The aim of this study was to explore whether the recent finding of G534E genetic variant can be replicated in a large sample of NMTC, including 11 members of four unrelated families with familial NMTC and 509 cases of sporadic pediatric (63 cases) and adult NMTC (446 cases). METHODS All exons and exon-intron boundaries of HABP2 were screened in 11 members of four families with familial non-syndromic NMTC using DNA isolated from peripheral leucocytes, polymerase chain reaction, and direct sequencing. The G534E variant was also screened for specifically in 229 cases of sporadic NMTC using DNA isolated from peripheral leucocytes and an additional 217 cases of NMTC using DNA isolated from formalin-fixed paraffin-embedded tumor tissues. As a control cohort, 190 healthy individuals without known thyroid disease were also studied for the presence of the G534E variant using DNA isolated from peripheral leucocytes. RESULTS None of the familial NMTC carried HABP2 mutations. Of 509 sporadic NMTC, only one case (0.2%) harbored the G534E variant. Similarly, only one case (0.5%) of the control group harbored the G534E variant. CONCLUSION In this study, HABP2 mutations were not found in familial NMTC, and the G534E variant is not the underlying genetic defect in a large sample of sporadic NMTC from the Middle East.

Targeted DNA Sequencing Detects Mutations Related to Susceptibility among Familial Non-medullary Thyroid Cancer. Sci Rep 2015; 5:16129.

Abstract
Some studies have demonstrated that familial non-medullary thyroid cancer (FNMTC) has a more aggressive clinical behavior compared to sporadic NMTC (SNMTC). However, FNMTC is difficult to differentiate from SNMTC by the morphology and immunohistochemistry. Although genes responsible for FNMTC were unclear, screening for rare germline mutations on known important tumor suppressor genes might offer more insights on predicting susceptibility to FNMTC. Here, a customized panel was designed to capture all exons of 31 cancer susceptive genes possibly related to FNMTC. Using next-generation sequencing we performed deep sequencing to achieve 500× coverage of the targeted regions. At the end 45 variants were identified in 29 of 47 familial patients and 6 of 16 sporadic patients. Notably, several germline mutations were found matching between paired FNMTC patients from the same family, including APC L292F and A2778S, BRAF D22N, MSH6 G355S and A36V, MSH2 L719F, MEN1 G508D, BRCA1 SS955S, BRCA2 G2508S, and a GNAS inframe insertion. We demonstrated a novel approach to help diagnose and elucidate the genetic cause of the FNMTC patients, and assess whether their family members are exposed to a higher genetic risk. The findings would also provide insights on monitoring the potential second cancers for thyroid cancer patients.

Abstract
BACKGROUND Familial nonmedullary thyroid carcinoma (FNMTC) is a variant of nonmedullary thyroid carcinoma(NMTC) with particular clinicopathologic features. In recent years, a number of studies have shown that FNMTC is more invasive than sporadic NMTC(SNMTC). The purpose of this study was to explore the differences in clinicopathologic features of FNMTC between different types of families and to determine in which of these families more invasive FNMTC occurred. METHODS We retrospectively reviewed all patients with thyroid carcinoma admitted to Peking Union Medical College Hospital from January 2009 to July 2013 in the database. Of all 2000 cases, 55 met the inclusive criteria for FNMTC and were studied. There are two different grouping methods. The first is that all samples were allocated to families with three or more first-degree relatives affected (FNMTC-3 group) and families with only two affected first-degree relatives (FNMTC-2 group). The second is that all patients were divided into families with three or more affected first-degree relatives over two generations (FNMTC-3-2 group) and the other families. We compared the clinicopathologic features such as sex, age, tumor size, multifocality, location, complications by thyroiditis, complications by benign thyroid nodules, surgical procedure, capsule invasion, histological type, lymph node metastases, tumor node metastasis stage, and BRAF mutation between FNMTC-2 group and FNMTC-3 group. We also made the same comparison between FNMTC-3-2 group and other families. RESULTS No pronounced differences in clinicopathological features were present between FNMTC-2 group and FNMTC-3 group. The proportion of FNMTC-3-2 group aged <45 years was significantly higher than that in the other families (58.8% vs. 26.3%, P = 0.021). A similar difference was found in the proportion of lymph node metastasis (64.7% vs. 34.2%, P = 0.035). CONCLUSIONS FNMTC-3-2 is more invasive than the other families. Early screening and positive treatment for members of these families are recommended.

Abstract
BACKGROUND The theory that short telomere length and genetic defects in maintaining telomere length are associated with familial nonmedullary thyroid cancer (FNMTC) is controversial. Thus, the aim of this study was to determine whether telomere length and genes involved in maintaining telomere length are altered in FNMTC. METHODS Blood samples were collected from 44 members (13 affected and 31 unaffected) of six families with FNMTC and from 60 controls. Quantitative polymerase chain reaction (Q-PCR) and reverse transcription PCR were performed to analyze relative telomere length (RTL), gene copy number, and mRNA expression of telomerase reverse transcriptase (hTERT), telomere repeat binding factor 1 (TRF1), telomere repeat binding factor 2 (TRF2), repressor activator protein 1 (RAP1), TRF1 interacting nuclear factor 2 (TIN2), tripeptidyl peptidase 1 (TPP1), and protection of telomere 1 (POT1). RESULTS Affected members had shorter RTL, as compared with unaffected members (0.98 vs. 1.23, p<0.01). There was no significant difference in hTERT, TRF1, TRF2, RAP1, TIN2, TPP1, and POT1 gene copy number or mRNA expression between affected and unaffected members. CONCLUSIONS RTL is shorter in affected members with FNMTC but is not associated with altered copy number or expression in hTERT, TRF1, TRF2, RAP1, TIN2, TPP1, and POT1. The small differences in RTL preclude the utility of RTL as a marker for FNMTC in at-risk individuals.

Abstract
BACKGROUND Cancer of the thyroid gland is rare in children and adolescents. A history of neck irradiation is a well-established risk factor for tumor development, and most previous reports focused on cases that were induced by radiation exposure. We present here a retrospective review of the clinical features, treatment, and long-term outcome of children and adolescents with papillary thyroid cancer (PTC) without a history of radiation exposure who were treated at our institution over a period of ~50 years. METHODS We retrospectively investigated 142 PTC patients without an irradiation history who were younger than 20 years of age when treated from 1961 to 2005 (17 males and 125 females; mean age = 16.3 ± 2.7 years; follow-up = 21.8 ± 12.0 years). The clinicopathological results were evaluated using the medical records. Disease-free survival (DFS) and cause-specific survival (CSS) were assessed with the Kaplan-Meier method and compared with the log-rank test. Parametric analyses were performed using Student's t test and nonparametric analyses were performed using the Mann-Whitney U test. RESULTS At diagnosis, three patients had distant lung metastasis and 33 had gross neck lymph node (LN) metastasis. All patients were treated with surgery (hemi/partial thyroidectomy in 45 patients, subtotal thyroidectomy in 85, total thyroidectomy in 12, no LN dissection in 50, central compartment dissection in 20, and modified radical neck dissection in 72), and postoperative external beam radiation therapy was administered to 59. Postoperative ablative therapy using I(131) was not performed in this series. Recurrence was found for regional LN (n = 25), lung (n = 9), remnant thyroid (n = 5), and others (n = 4). DFS and CSS at 40 years were 74.1 and 97.5%, respectively. DFS was significantly worse in patients aged <16 years with a family history of thyroid cancer, preoperative neck gross LN metastasis, maximum tumor diameter, and extrathyroidal invasion. Preoperative gross neck LN metastasis and distant metastasis at diagnosis were significant factors for CSS. No other factors contributed to DFS and CSS. When the clinical features of children and adolescents were compared, the incidence of preoperative gross neck LN metastasis and distant metastasis at diagnosis and tumors with a maximum diameter >10 mm were significantly higher in the children group than in the adolescent group. DFS was significantly shorter in the children group than in the adolescent group, but no significant difference was found in CSS between these two groups. CONCLUSIONS The prognosis of PTC in children and adolescents is excellent, regardless of the extent of thyroidectomy and LN dissection. We recommend that only children or adolescents with preoperative gross neck LN metastasis and distant metastasis at diagnosis should be subjected to postoperative ablative therapy.

Abstract
BACKGROUND The occurrence of familial papillary thyroid cancer (FPTC) is well established but no susceptibility genes for this disease have been discovered. Our group has recently demonstrated that patients with FPTC have shorter telomeres, not associated with mutations in telomerase reverse transcriptase, gene than patients with sporadic papillary thyroid cancer (SPTC), healthy subjects (HS), and unaffected family members (UFMs). Several diseases, however, have short telomeres associated with mutations in the telomerase RNA component (TERC) gene or in the shelterin complex (POT1, RAP1, TIN2, TPP1, TRF1, and TRF2) genes. The objective of the present study was to verify whether short telomeres observed in FPTC patients were related to mutations in TERC or shelterin genes. METHODS Sixty-six patients with FPTC, 46 UFMs, 111 patients with SPTC, and 153 HS were analyzed by polymerase chain reaction followed by denaturing high performance liquid chromatography analysis and direct sequencing for the presence of TERC or shelterin gene mutations. When present, single-nucleotide polymorphisms were tested by χ(2) analysis at the genotypic, allelic, and haplotypic levels. RESULTS The entire sequence of the TERC gene was analyzed with particular attention to known mutations known to be associated with short telomeres. All samples appeared to be homozygous wild type for A-771G, C-99G, G305A, G322A, C323T, C408G, G450A, T467C, G508A, A514G, G623A, and C727G substitutions and for the 378Δ→3' deletion in the TERC gene. In addition, upon analysis of all samples for shelterin proteins, we observed a significant decrease in POT1 and RAP1 protein expression in the blood of FPTC patients compared with SPTC subjects. However, no mutations or polymorphisms were found when in the coding sequences of both genes. CONCLUSIONS To our knowledge this is the first study of TERC mutations or alterations in the shelterin complex in relation to FPTC. Shorter telomeres observed in FPTC are not linked to mutations or polymorphisms in TERC, POT1, or RAP1 genes.

Abstract
Background. Whether or not the familial form of papillary thyroid carcinoma is more aggressive than the sporadic form of the disease remains controversial. Methods. To explore this question and whether or not increased aggressiveness is more apparent in families with multiple affected members, we performed a chi square by trend analysis on our patients clinical and pathologic data comparing: first degree families with three or more affected members versus first degree families with two affected members versus sporadic cases of papillary thyroid carcinoma. Results. No statistically significant trends were seen for any presenting surgical pathology parameter, age at presentation, length of follow-up or gender distribution. The familial groups exhibited significant trends for higher rates of reoperation (P = 0.05) and/or requiring additional radioactive iodine therapy (P = 0.03), distant metastases (P = 0.003) and deaths (P = 0.01). These aggressive features were most apparent in certain families with three or more affected members. Conclusions. Using the chi square by trend analysis, a significant trend was seen for the familial form of papillary thyroid cancer to possess more aggressive features than the sporadic disease. Prompt recognition of the familial nature of the disease may provide earlier diagnosis and treatment in similarly affected family members.

Abstract
OBJECTIVE: To evaluate the frequency of thyroid cancer and thyroid dysfunction in first-degree relatives of thyroid cancer patients, and to determine if there is a difference between familial and sporadic thyroid cancer. SUBJECTS AND METHODS: Fifteen first-degree relatives of seven families with at least two family members with thyroid cancer (TC) were compared with 128 first-degree relatives of 45 families with only one family member affected. Laboratory and ultrasound evaluation, fine-needle aspiration biopsy and thyroid surgery were used as normally done in clinical practice. RESULTS: Thyroid dysfunction was similar between the two groups. The frequency of TC and autoimmunity in the group that had two relatives with known thyroid cancer was higher, compared with the families that had sporadic thyroid cancer among their family members (40% vs. 2%, p = 0.0001). CONCLUSION: Frequency of TC increases when more than one member of the family is affected. These findings suggest that these relatives should be screened more frequently than individuals in families in which only one case of TC is observed.

Abstract
PURPOSE Approximately 5% of differentiated thyroid carcinomas are of familial origin. These familial nonmedullary thyroid carcinomas (FNMTC) have an increased risk of multifocal disease and lymph node involvement. Consequently, higher recurrence rates and decreased disease-specific survival rates are described. The best surgical approach is discussed controversially. PATIENTS AND METHODS A survey among the international members of the German Society of Endocrine Surgeons revealed 20 families with two or more first-degree relatives with FNMTC. The mean age of the 41 patients (30 female, 11 male) with FNMTC was 40.6 years (18-73 years). RESULTS Total thyroidectomy was performed in 31 of 41 patients (76%). Ninety-five percent of the tumors were papillary carcinomas. Two of 41 patients had follicular carcinomas. Ten patients (24%) with papillary carcinomas were diagnosed with Hashimoto's thyroiditis. The mean tumor size was 1.45 cm. FNMTC was multifocal in 12 patients (29%). A systematic lymph node dissection was performed in 21 of 41 patients (51%). Lymph nodes metastases were found in seven of these 21 patients. Twenty-eight of the patients (68%) underwent postoperative radioiodine ablation. After a mean follow-up of 7.2 years, 39 patients (95%) were disease free. One patient developed local recurrence and lung metastases, 10 and 25 years, respectively, after initial diagnosis. Another patient died 2 years postoperatively from advanced metastatic disease. CONCLUSIONS FNMTC is associated with an early onset of small, mostly papillary thyroid carcinomas and an increased risk of multifocality and lymph node involvement. Total thyroidectomy and systematic neck dissection are recommended together with radioiodine ablation. Screening for first-degree relatives should start at age 18 years.

Abstract
The follicular cell—derived thyroid cancers (termed nonmedullary thyroid cancers—NMTCs) occur mostly sporadically, but intriguingly, NMTC has the highest familial risk among all cancer sites. This epidemiological observation is strengthened by the clinical occurrence of NMTC in familial aggregation (FNMTC) and by the detection of chromosomal loci in linkage with the disease phenotype. FNMTC loci have been proposed at 14q, 1q21, 19p13.2, 2q21, 8p23, 8q24, 1q21, and 6q22, but to date, no causative mutations have been linked to FNMTCs. In this review, the authors focus on the clinical, morphological, and molecular aspects that characterize familial tumors. Some morphological patterns may alert for a familial disease. FNMTCs share several of the somatic molecular changes associated with sporadic tumors. New genes affected by somatic changes have been disclosed within regions harboring FNMTC loci.

Abstract
Hereditary thyroid carcinomas are present in about 5% of differentiated (DTC) and 25% of medullary thyroid carcinomas (MTC). They are part of a multiorgan tumour syndrome (e. g. FAP Gardner's syndrome with DTC and MEN 2 syndrome with MTC) or confined to the thyroid gland. Hereditary thyroid carcinomas typically show multifocal growth and occur in young patients. Due to germ cell mutations as the underlying cause of disease, partial thyroidectomies that may be justified in early sporadic carcinomas are not indicated in this type of tumours. In the case of hereditary DTC, the genetic basis of the disease has been demonstrated only in syndromatic tumour variants. In most nonsyndromatic cases, specific genetic alterations have not yet been identified. In both types of hereditary DTC, prophylactic thyroidectomy is not warranted due to the favourable prognosis of tumours that do not differ from sporadic ones. Point mutations of the RET proto-oncogene have been known for 15 years to be the genetic basis of hereditary MTC. Recently several new mutations were discovered; however, final conclusions regarding their clinical significance are not possible at present. Basically it has been shown that the clinical aggressivity of tumour development follows a genotype-phenotype correlation (risk groups 1-3). However, in mutations of all risk classes there exists a wide spectrum of different stages of hereditary C-cell disease in individual risk groups. Regarding time and extent of prophylactic thyroidectomy (without or with lymph node dissection) a combined molecular-biochemical concept including the use of pentagastrin-stimulated calcitonin values is therefore recommended.

Abstract
BACKGROUND Differentiated papillary thyroid cancer is mostly sporadic, but the recurrence of the familial form has been reported. Short or dysfunctional telomeres have been associated with familial benign diseases and familial breast cancer. OBJECTIVE The aim of our work was to study the telomere-telomerase complex in the peripheral blood of patients with familial papillary thyroid cancer (FPTC), including the measurement of relative telomere length (RTL), telomerase reverse transcriptase (hTERT) gene amplification, hTERT mRNA expression, telomerase protein activity, and search of hTERT or telomerase RNA component gene mutations. PATIENTS Cumulating a series of patients seen at the University of Siena and a series at the University of Rome, the experiments were conducted in 47 FPTC patients, 75 sporadic papillary thyroid cancer (PTC) patients, 20 patients with nodular goiter, 19 healthy subjects, and 20 unaffected siblings of FPTC patients. RESULTS RTL, measured by quantitative PCR, was significantly (P < 0.0001) shorter in the blood of FPTC patients, compared with sporadic PTCs, healthy subjects, nodular goiter subjects, and unaffected siblings. Also by fluorescence in situ hybridization analysis, the results confirmed shorter telomere lengths in FPTC patients (P = 0.01). hTERT gene amplification was significantly (P < 0.0001) higher in FPTC patients, compared with the other groups, and in particular, it was significantly (P = 0.03) greater in offspring with respect to parents. hTERT mRNA expression, as well as telomerase activity, was significantly higher (P = 0.0003 and P < 0.0001, respectively) in FPTC patients, compared with sporadic PTCs. RTL, measured in cancer tissues, was shorter (P < 0.0001) in FPTC patients, compared with sporadic PTCs. No mutations of the telomerase RNA component and hTERT genes were found. CONCLUSION Our study demonstrates that patients with FPTC display an imbalance of the telomere-telomerase complex in the peripheral blood, characterized by short telomeres, hTERT gene amplification, and expression. These features may be implicated in the inherited predisposition to develop FPTC.

Abstract
Linkage studies have identified susceptibility loci for familial nonmedullary thyroid cancer (FNMTC), with and without cell oxyphilia, at chromosomal regions 19p13.2 and 2q21. There are few genetic analyses of FNMTC tumours reported at the present time and the eventual gene involved was not identified yet. The aim of this study was to assess the occurrence of loss of heterozygosity (LOH) at these loci in the tumours from familial clusters of NMTC. We have analysed LOH in 14 tumours from 9 two-case familial clusters of NMTC. Using paired blood (normal) and tumour DNA samples, we have genotyped ten microsatellite and one SNP markers throughout 19p13.2 and fourteen microsatellite markers at 2q21. Overall, eight (57%) and two (14%) out of the fourteen tumours analysed exhibited LOH at 19p13.2 and 2q21, respectively. In two families (22%), LOH for the same markers was demonstrable in the tumours of the two members of the same family. In one family (11%) LOH was demonstrable at both loci analysed. In four two-case familial clusters (44%), LOH at the 19p13.2 locus was found in only one of the tumour cases analysed. Detailed haplotype analysis showed that, in two families (22%), the pattern of LOH in tumours was consistent with selective retention of the haplotype shared by affected members. In the remaining cases, it was consistent with random allelic losses. In conclusion, we report the finding of LOH at the 19p13.2 and 2q21 loci in tumours from familial clusters of NMTC, providing evidence that inactivation of putative genes in these regions, acting as tumour-suppressors, may be involved in the development of tumours in the context of FNMTC.

Abstract
OBJECTIVE In recent years many authors have reported an increase in thyroid cancer (TC) incidence in several countries. The cause of such phenomenon remains unclear. DESIGN This study was designed to estimate the incidence of TC in Basilicata, the smallest region of Southern Italy with a population of 596,546 people, between 2001 and 2004. MAIN OUTCOME A total of 302 cases of TC were identified. The annual incidence of TC changed over the years, from 10.0 per 100,000 people in 2001 to 15.7 per 100,000 people in 2004. The number of new TC cases per 100,000 people increased an average of 16% per yr. Median age at diagnosis was 49 yr. The most frequent histotype was papillary TC (PTC) (73.2%). In 20 (6.6%) patients with PTC, we identified at least one first-degree relative affected by differentiated TC. CONCLUSIONS The present study shows a high incidence of sporadic and familial non-medullary TC in Basilicata. The reason for this finding may be related to several factors discussed in the paper. Further studies evaluating the trends in the incidence of TC in Basilicata in the future could provide some answers for the potential pathogenetic hypothesis.

Abstract
Childhood thyroid cancers are uncommon and have a fairly good prognosis. Papillary adenocarcinoma is the most prevalent malignant tumor of the thyroid in children and adults with radiation-induced or sporadic cancer. The incidence of thyroid cancer in children increased dramatically in the territories affected by the Chernobyl nuclear accident; this increase is probably attributable to (131)I and other short-lived isotopes of iodine released into the environment. There was a broad range of latency periods in children who developed thyroid cancer; some periods were less than 5 years. The mutational spectrum of childhood thyroid cancers demonstrates that gene rearrangements that lead to the activation of mitogen-activated protein kinase signaling seem to have a pivotal role; point mutations are rare. So far none of the cancer genes or tumor suppressors, or a peculiar gene expression pattern, has been specifically implicated in radiation-induced thyroid carcinogenesis. The frequency of certain oncogenes does, however, vary in tumors that develop after different periods of latency. Such differences in the distribution of gene abnormalities in radiation-related cancers implies that they associate with patients' age at exposure and diagnosis, clinicopathological manifestations of disease and depend on an individual's genetic characteristics. Here we review results of pathological and molecular studies in childhood thyroid cancer.

Abstract
UNLABELLED Approximately 5% of nonmedullary thyroid cancers are of familial origin. When two or more family members are diagnosed with nonmedullary thyroid cancer in the absence of other known associated syndromes it is termed familial nonmedullary thyroid cancer (FNMTC). The genetic inheritance of FNMTC remains unknown, but it is believed to be an autosomal dominant mode of inheritance with incomplete penetrance and variable expressivity. FNMTC has been shown to be more aggressive and to have a worse prognosis than sporadic nonmedullary thyroid cancer. For example, studies have demonstrated that individuals with FNMTC have an increased risk of multifocal disease, local invasion, and lymph node metastases. These aggressive features appear to contribute to the higher recurrence rate and decreased disease-free survival seen in FNMTC patients compared to those with sporadic differentiated thyroid cancer. This article is an overview of the literature available in the English language discussing FNMTC. Critical questions regarding the screening, management, and follow-up of these patients are addressed with answers proposed based on the available literature. The quality of the evidence is ranked according to Sackett's criteria. Overall, the literature quality is somewhat limited, based on the low prevalence of FNMTC, the difficulty in identifying familial cases, the variable study designs, and limited long-term follow-up. CONCLUSIONS To date, the optimal clinical approach is yet to be established, but improved awareness and screening will permit earlier detection, more timely intervention, and hopefully improved outcomes for patients and their families.

Abstract
The presence of papillary carcinoma of the thyroid in multiple generations of one kindred is a statistical impossibility as an occurrence of chance. However, traditional and molecular genetic analyses to date have failed to support the notion of a single gene mutation or identify one, in distinct contrast to medullary carcinoma of the thyroid. Findings to date, outside of distinct multicancer syndromes, suggest the interplay of inherited susceptibility and other factors, such as environmental exposures. It is possible that the main identifiable genetic risk factors at this time are the presence of multinodular goiter or Hashimoto's thyroiditis within the family.

Abstract
BACKGROUND Nonmedullary thyroid carcinomas (NMTCs) originate from the thyroid epithelial cells and, until recently, were thought to arise sporadically without an inherited genetic predisposition. However, evidence of a familial predisposition to NMTC is accumulating. METHODS This review addresses the strengths, weaknesses, and clinical implications of the observations indicating an inherited genetic predisposition to NMTC. These observations include epidemiologic studies, descriptions of large kindreds, and genetic analyses. RESULTS Familial NMTC (FNMTC) may be caused by an inherited genetic predisposition and can be divided into two groups. The first group has an increased prevalence of NMTC within a familial cancer syndrome with a preponderance of nonthyroidal tumors. In the second group the predominant neoplasm is NMTC, although other neoplasms may occur with increased frequency. These disorders are the focus of this review. CONCLUSIONS A family history in NMTC patients should be directed at detecting those familial tumor syndromes with a preponderance of NMTC as well as those familial tumor syndromes enriched in NMTC but with a preponderance of nonthyroidal tumors. Since the recurrence rates may be greater in FNMTC than in sporadic NMTC, careful monitoring is indicated for affected individuals. The advantages and disadvantages of screening asymptomatic members of FNMTC kindreds with thyroid ultrasound are discussed, and the final decision is deferred to the treating physicians and their patients. It is hoped that positional cloning research will identify the FNMTC susceptibility genes.

Abstract
Clinical and genetic studies of familial nonmedullary thyroid cancer (FNMTC) have yielded conflicting results concerning the aggressiveness of the tumors, and uncertainty of their genetic makeup. In most reports of multiply affected families, the composition of the kindreds has favored families of 2 affected members. Using data for differentiated thyroid cancer (DTC) provided by the Surveillance Epidemiology and End Results (SEER) branch of the National Cancer Institute, and fine-needle aspiration data from Mayo Clinic, I found that the likelihood of 2 cases of sporadic DTC (RR) in a 9-member first-degree family was 1.25% of all DTC families, amounting to 39.4% of 306 multi-hit families reported in the literature. To study the remaining affected families I used the Bernouilli trials model of exact probability. The 60.6% of non-RR, multiply affected families are mostly concentrated in kindreds of 2 to 5 affected members. In 2-hit families, 62%-69% of affected members are sporadic (RR) cases. In families having 3 or more affected members, fewer than 6% have 1 or more sporadic (R) cases, and fewer than 0.15% have 2 or more. In families of 3 to 5 affected members, more than 96% of affected members have the familial (F) trait. Approximately 1 of 338 DTC cases carries the F-trait. Since approximately 40% of multiply affected member first-degree kindreds of DTC, and a significant majority of 2-hit families, are composed of clinically evident, sporadic cases only clinical and genetic investigations of FNMTC should center on families of 3 or more affected members.

Abstract
The familial form of nonmedullary thyroid carcinoma (FNMTC) has been recognized as a distinct clinical entity and is characterized by multifocality and a more severe phenotype than its sporadic counterpart. The majority of FNMTC pedigrees are small in size, show variable modes of inheritance, and may present with a variety of additional benign thyroid disorders. The existence of marked phenotypic differences between FNMTC families suggests that there is genetic heterogeneity. Recent studies have mapped a susceptibility locus for FNMTC at 2q21. This locus appears particular relevant to families with at least one case of the follicular variant of papillary thyroid cancer (fvPTC). We describe the clinical and pathologic characteristics of a large three-generation fPTC kindred, with two of the four PTC patients presented with the follicular variant of PTC. It is of interest the occurrence of PTC in three siblings within a period of 3 years. In addition, multinodular goiter (MNG) was diagnosed in seven individuals, lymphocytic thyroiditis in four, while one diagnosed with a benign adenoma. From the PTC patients, one had MNG and fvPTC, one MNG, lymphocytic thyroiditis and papillary pattern of PTC, one lymphocytic thyroiditis and fvPTC, and one MNG and papillary pattern of PTC. The inheritance pattern was autosomal dominant with incomplete penetrance and women were affected more frequently than men. Considering all PTC-affected individuals, the limit of detection (LOD) score we got for this family on 2q21 was 0.5. The low LOD score is caused by a PTC patient who does not share the affected haplotype, suggesting that maybe a new locus for PTC predisposition is present in this kindred. Linkage analysis also excluded TCO, MNG, and fPTC/PRN as susceptibility loci to FNMTC in this family.

Abstract
CONTEXT Reliable data on familial risks are important for clinical counseling and cancer genetics. OBJECTIVE We wanted to define familial risks for histopathology-specific nonmedullary thyroid cancers through parental and sibling probands. SETTING The study examines the nationwide Swedish Family-Cancer Database on 10.5 million individuals, containing families with parents and offspring. PATIENTS Cancer data were retrieved from the Swedish Cancer Registry from years 1958 to 2002, including 3292 patients with thyroid adenocarcinoma. The Systematized Nomenclature of Medicine histology was available from 1993 onward, with 1449 papillary, 288 follicular, 148 anaplastic, and 68 Hurthle cell tumors. MAIN OUTCOME MEASURES Familial risk for offspring was defined through standardized incidence ratio, adjusted for many variables. RESULTS The familial risk for papillary carcinoma was 3.21 and 6.24 when a parent and a sibling, respectively, were diagnosed with thyroid cancers. There was an apparent gender preference, particularly among sisters, whose risk was 11.19. The risks were highest for early onset cancers. Thyroid adenocarcinoma was shown to be associated with melanoma and connective tissue tumors, and probably also with neurinomas (schwannomas). Associations found in single comparisons with papillary thyroid cancer and other sites included right-sided colon, breast, ovarian, and kidney cancers. Hurthle cell tumors were associated with Hodgkin's and non-Hodgkin's lymphoma, but the numbers of cases were small. CONCLUSIONS The present findings were based on a limited number of cases, but they display a complex and heterogeneous pattern of familial nonmedullary thyroid cancer. The high risk for papillary carcinoma among women requires clinical attention, although the absolute risks for this rare cancer are still low.

Abstract
Childhood papillary thyroid carcinoma is associated with more locally aggressive and more frequent distant disease than its adult counterpart. Recurrence rates tend to be higher in children, but cause-specific mortality remains low. Optimal initial treatment of childhood papillary thyroid carcinoma should include total or near-total thyroidectomy and central compartment node clearance. Modified neck dissections should be performed for biopsy-proven lateral neck disease. Every effort should be made to maintain parathyroid and laryngeal nerve function. Radical neck dissections are to be avoided. Radioiodine remnant ablation (RRA), appropriate thyroid hormone suppressive therapy (THST), and judicious use of therapeutic doses of (131)I are applied to achieve a disease-free status, which is most often confirmed by negative neck ultrasonography, negative whole-body scan (either withdrawal or recombinant human thyroid-stimulating hormone-stimulated), and extremely low levels of serum thyroglobulin. Appropriate utilization of (131)I, THST, repeat surgery, external beam radiotherapy, and rarely chemotherapy may provide long-term palliation and some cures in patients with recurrent/persistent disease. Follow-up should be lifelong, and the care of children after age 17 should subsequently be transferred to adult-care endocrinologists with expertise in managing thyroid neoplasia. Optimal surgical management can be achieved if adequate operations are routinely carried out by "high-volume" thyroid surgeons with expertise in the care of children. Nowhere is a multidisciplinary approach (endocrinologists, surgeons, nuclear medicine physicians, pediatricians, pathologists, oncologists) more critical than in the long-term management of papillary thyroid carcinoma that presents during childhood.

Abstract
Mass screening for the purpose of detecting thyroid cancer at its earliest stage may not be recommended at the present time, but screening focused on certain risk groups is advocated. Familial nonmedullary thyroid carcinoma (FNMTC) is a distinct clinical entity with a high incidence of multifocality and association with multiple benign nodules. FNMTC patients have shorter disease-free survival than do sporadic disease patients because of frequent locoregional recurrence. Screening by neck ultrasonography was performed for symptom-free family members of patients with FNMTC. A total of 149 subjects representing 53 FNMTC families were examined in this study. The average age of the patients was 41.0+/-19.0 years (range 3-76 years) with a female/male ratio of 104:45. At least one thyroid nodule was found in 77 (51.7%) of the 149 patients. Surgery was performed in 18 patients, and thyroid cancer was discovered in 15 of them (10.1%; 14 women, 1 man; 32-61 years of age). Papillary thyroid cancer (PTC) was found in 14 and follicular thyroid cancer combined with PTC in 1. The tumors averaged 9.1+/-5.4 mm (3-21 mm) in greatest diameter. Intraglandular metastases were found in 7 (47%) of the 15 patients with thyroid cancer. Lymph node metastases were found in 6 (43%). Ultrasonographic screening for FNMTC family members may enable the discovery of asymptomatic thyroid cancer. Because of the high incidence of intraglandular and lymph node metastases, we recommend screening with ultrasonography for early detection in family members of patients with FNMTC.

Abstract
In a population-based study of 313 case-control pairs in Kuwait, we evaluated whether a family history of benign thyroid disease (BTD) and thyroid or other cancers was associated with an increased risk of thyroid cancer, the second most common neoplasm among women in this and several other Arab countries in the Gulf region. Family history of BTD was reported by 78 (24.9%) cases and 40 (12.8%) controls in 132 and 57 relatives, respectively. There was an approximately 2-fold increased risk of thyroid cancer in individuals who had a mother (Odds Ratio (OR)=2.3; 95% Confidence Intervals (95% CI): 1.1-5.1), sister(s) (OR=2.6; 95% CI: 1.3-5.3) or aunt(s) (OR=2.1; 95% CI: 0.9-5.3) with BTD; there was also a significant trend in increasing risk with an increasing number of affected female relatives (P<0.0001). Stratification by age at diagnosis of the case showed that individuals aged </= 35 years, who had an affected first- or second/third-degree relative(s), had an approximately 3-fold increased risk of the cancer. Family history of thyroid cancer was reported by 9 (2.9%) cases in 13 relatives (11 females, 2 males) and by 3 controls in 3 relatives (all females) (OR=3.0; 95% CI: 0.8-11.1). The OR for all hormone-related cancers combined was 1.5 (95% CI: 0.8-2.6). There was no clear association with family history of breast or any other common cancer. Our data suggest that a family history of BTD is associated with an increased risk of thyroid cancer, and point to the role of familial susceptibility to BTD and thyroid cancer in the Kuwaiti population.

Abstract
Although genetical inheritance is an well established fact with medullary cancer of thyroid no such clear cut proof exist with papillary or follicular neoplasm of thyroid It's a fact that family clusters of non-medullary thyroid tumor exist, it requires more precise identification of genetical inheritance These clusters behave in a separate way and requires a more aggressive treatment for low recurrence rate and better prognosis.

Abstract
AIMS Familial occurrence of papillary thyroid cancer is uncommon. The purpose of this study was review our own experience in a series of 267 papillary thyroid cancers. METHODS We analysed the clinical records of 267 consecutive patients operated on for papillary thyroid cancer (PTC) in our hospital between June 1980-March 2000. RESULTS We identified a family history in three families (6 patients), which results in a 2.25% familial papillary thyroid carcinoma (FPTC) rate. Pathology findings revealed that the tumour was multifocal and bilateral in 2 patients. Lymph-node metastases were found in 4 patients. They are all alive with a mean time of follow-up of 74.3 months (range 2-120). CONCLUSIONS We recommend that patients with familial disease should be treated according to the disease stage and other risk factors, similar to those with sporadic differentiated papillary thyroid cancer. We encourage the further reporting and pedigree analysis to identify patients affected by FPTC.

Thyroid nodules are found in 4 to 7% of the population, and with the increased use of radiographic methods, incidental nodules are becoming more prevalent. Only 5% of all nodules will be malignant, and thyroid cancer accounts for only 0.4% of all cancer deaths. The preferred diagnostic approach is early referral, avoidance of numerous radiologic evaluations, and early performance fine-needle aspiration. This article reviews the literature of the last 12 months and discusses some of the new molecular, genetic, and immunostaining techniques in the evaluation of thyroid nodules.

Abstract
Oxyphilic tumors of the thyroid gland are rare tumors characterized by the presence of H?rthle cells - mitochondrion-rich, eosinophilic epithelial cells. H?rthle cell carcinomas (HCC) of the thyroid behave in a more aggressive fashion as compared to other well-differentiated thyroid cancers. Many recent studies have been focused on the further elucidation of pathogenesis and the role of mitochondrial hyperplasia in carcinogenesis of these neoplasms. The importance of combining morphological and genetic approaches in the study of HCC has been emphasized by the difficulties encountered in establishing adequate differential diagnostic criteria between benign and malignant forms, as well as by the resistance of HCC to radio and chemotherapy. It has been well documented that the H?rthle cells are characterized by profound aberrations in the nuclear and mitochondrial genome and by alterations in oncogenes, tumor suppressor genes and other key genes involved in energy metabolism, proliferation and apoptosis.

Abstract
BACKGROUND Occurrence in a familial setting is well established for medullary thyroid carcinoma (MTC) and has been more recently reported for papillary thyroid cancer (PTC). Germline mutations or rearrangements of the RET proto-oncogene are the genetic background of the majority of hereditary MTCs and of about 25-40% of PTCs. PATIENTS A large multigenerational familial medullary thyroid cancer (FMTC) family, comprised of four generations and a total of 60 subjects, has been fully evaluated. Studies on germline RET mutations and polymorphisms, on somatic RET activation and on haplotyping with RET-linked markers, were performed. RESULTS RET mutational analysis revealed a rare missense point mutation in exon 15 of RET (A891S), associated with FMTC. Haplotype analysis showed a co-segregation between the allelic variant 5 of D10S578 marker (which is tightly linked to the RET locus) and the RET mutation. Two patients, from different branches of the family, did not harbour the point mutation A891S despite histological confirmation of MTC. In these cases, haplotype analysis excluded the involvement of the RET gene itself in the pathogenesis of the MTC. In three patients, the coexistence, in different foci, of medullary and papillary thyroid cancer was documented. The genetic studies did not show ret/PTC rearrangements. The microsatellite analysis excluded co-segregation of RET locus with the MTC/PTC phenotype. CONCLUSIONS We report a full clinical and molecular analysis of a large FMTC kindred with an uncommon RET mutation. In two family members, phenotype and genotype were not concordant, representing the first evidence of FMTC phenocopies. Furthermore, the association of familial forms of medullary and papillary thyroid cancers has been found in 30% of patients undergoing thyroidectomy for MTC. In these situations, genetic analyses excluded the possible germline involvement of RET. Though FMTC phenocopies are likely to represent an exceptional finding, such a possibility should be taken into account in the genetic counselling for MEN 2 syndromes.

Abstract
Papillary thyroid carcinoma (PTC) is clinically heterogeneous. Apart from an association with ionizing radiation, the etiology and molecular biology of PTC is poorly understood. We used oligo-based DNA arrays to study the expression profiles of eight matched pairs of normal thyroid and PTC tissues. Additional PTC tumors and other tissues were studied by reverse transcriptase-PCR and immunohistochemistry. The PTCs showed concordant expression of many genes and distinct clustered profiles. Genes with increased expression in PTC included many encoding adhesion and extracellular matrix proteins. Expression was increased in 8/8 tumors for 24 genes and in 7/8 tumors for 22 genes. Among these genes were several previously known to be overexpressed in PTC, such as MET, LGALS3, KRT19, DPP4, MDK, TIMP1, and FN1. The numerous additional genes include CITED1, CHI3L1, ODZ1, N33, SFTPB, and SCEL. Reverse transcriptase-PCR showed high expression of CITED1, CHI3L1, ODZ1, and SCEL in 6/6 additional PTCs. Immunohistochemical analysis detected CITED1 and SFTPB in 49/52 and 39/52 PTCs, respectively, but not in follicular thyroid carcinoma and normal thyroid tissue. Genes underexpressed in PTC included tumor suppressors, thyroid function-related proteins, and fatty acid binding proteins. Expression was decreased in 7/8 tumors for eight genes and decreased in 6/8 tumors for 19 genes. We conclude that, despite its clinical heterogeneity, PTC is characterized by consistent and specific molecular changes. These findings reveal clues to the molecular pathways involved in PTC and may provide biomarkers for clinical use.

Abstract
The genetic basis for nonmedullary forms of thyroid cancer (NMTC) is less well established than that of medullary thyroid cancer. However, epidemiological and family studies suggest that a proportion of NMTC may be due to inherited predisposition. To estimate the familial risk of thyroid cancer, we conducted a hospital-based case-control study at the Princess Margaret Hospital in Toronto, Ontario, Canada, and at 2 university hospitals in Montréal, Québec, Canada. We obtained pedigrees from 339 unselected patients diagnosed with NMTC and from 319 unaffected ethnically matched controls. Family histories of cancer were obtained from the cases and controls for 3292 first degree relatives of cases and controls. Seventeen cases (5.0%) and 2 controls (0.6%) reported at least one first degree relative with thyroid cancer. In relatives of patients with thyroid cancer, the incidence of any type of cancer (including NMTC) was 38% higher than in relatives of controls (incidence rate ratio, 1.4; 95% confidence interval, 1.1-1.7). The relative risk for thyroid cancer was 10-fold higher in relatives of cancer patients than in controls (incidence rate ratio, 10.3; 95% confidence interval, 2.2-47.6). Our findings suggest that hereditary or other familial factors are important in a small proportion of NMTC. Molecular studies are needed to determine the genetic basis of cancer susceptibility in these families.

Abstract
Cancer is a disease of genes. Detection of genetic abnormalities associated with cancers of various cell types can now be used for genetic counseling, diagnosis or treatment selection. In the case of thyroid cancer, genetic testing for mutations of the RET oncogene has had a profound effect on the management of medullary thyroid carcinomas. There is also considerable information on the genetic changes associated with development and progression of cancers of thyroid follicular cells, although these have not yet proven to be of practical value for clinical diagnosis or to guide prognosis and therapy.

Abstract
The authors report the occurrence of papillary carcinoma of the thyroid in nine first-degree relatives of four families among a consecutive series of 97 patients with papillary carcinoma of the thyroid who were operated on from 1991 to 1998. Total thyroidectomy was performed in all cases. All patients are alive without evidence of disease after a mean follow-up period of 43 months. Since in our series familial papillary carcinoma of the thyroid was found in 9.3% of patients, we suggest an adequate screening among first-degree relatives of all patients with papillary thyroid carcinoma. Because of reported aggressive behaviour of familial papillary carcinoma of the thyroid, aggressive surgical treatment plus post-operative thyroid remnant ablation with radio-iodine should be warranted in all patients.

Abstract
BACKGROUND The aggressiveness of familial non-medullary thyroid cancer (FNMTC) has been a subject of debate. The purpose of the study was to determine whether FNMTC is more aggressive than sporadic thyroid cancer. METHODS A multicenter retrospective matched-case control study of FNMTC versus sporadic non-medullary thyroid cancer was conducted. Disease-free survival (time to recurrence) for both groups was compared. RESULTS Forty-eight familial cases were compared with 144 age-, gender-, and stage-matched controls. Patients with FNMTC had a significantly shorter disease-free survival compared with sporadic non medullary thyroid cancer. Patients with FNMTC who presented with evidence of distant metastasis, or who were from families with more than 2 thyroid cancer-affected members, had the worst prognosis. The available staging systems were less likely to predict the outcome in patients with FNMTC than in patients with sporadic non-medullary thyroid cancer unless one accounted for the strength of family history in the staging system. CONCLUSIONS FNMTC is more aggressive than sporadic non-medullary thyroid cancer. The best predictors of a poor outcome in patients with FNMTC are the number of family members affected by thyroid cancer and evidence of distant metastasis.

Abstract
Papillary thyroid carcinoma usually is sporadic, but may occur in a familial form. The complete clinical and pathological phenotype of familial papillary thyroid carcinoma (fPTC) has not been determined, and the susceptibility gene(s) is unknown. We investigated the clinical and pathological characteristics of an unusually large three-generation fPTC kindred to characterize more fully the clinical phenotype. We performed linkage analysis to determine the chromosomal location of a fPTC susceptibility gene. In addition to the known association of fPTC with nodular thyroid disease, we observed the otherwise rare entity of papillary renal neoplasia (PRN) in two kindred members, one affected with PTC and the other an obligate carrier. The multifocality of PRN in one subject adds weight to the likelihood of a true genetic predisposition to PRN. Both genetic linkage and sequence analysis excluded MET, the protooncogene of isolated familial PRN, as the cause of the fPTC/PRN phenotype. A genome-wide screening and an investigation of specific candidate genes demonstrated that the fPTC/PRN phenotype was linked to 1q21. A maximum three-point log of likelihood ratio score of 3.58 was observed for markers D1S2343 and D1S2345 and for markers D1S2343 and D1S305. Critical recombination events limited the region of linkage to approximately 20 cM. A distinct inherited tumor syndrome has been characterized as the familial association of papillary thyroid cancer, nodular thyroid disease, and papillary renal neoplasia. The predisposing gene in a large kindred with this syndrome has been mapped to 1q21.

Abstract
This paper describes the pathology of thyroid tumours showing an autosomal mode of inheritance linked to a gene that maps to chromosome 19p13.2. All the affected members from the family (seven males and two females; mean age 23 years) were clinically euthyroid and presented with nodular goitre; tumour recurrence after thyroidectomy was observed in four. In four of the five patients studied, the tumours were multifocal, bilateral well demarcated or encapsulated and composed of follicles, papillae, trabeculae/solid areas (often resembling hyalinizing trabecular adenoma of the thyroid) or an admixture, formed by cells with pale to intense cytoplasmic eosinophilia. A diagnosis of multiple adenomatous goitre was made in the thyroidectomy specimen from two patients, while the other two patients showed, in addition to multiple adenomas, a co-existent oxyphil papillary carcinoma. The fifth patient had an oxyphil cell carcinoma. All tumours were of follicular cell origin as shown by immunocytochemistry. Less than a third of the benign tumours and all three carcinomas showed a variable number of neoplastic cells diffusely immunostained for mitochondria. Histological findings of a 'multiple adenomatous goitre', non-endemic 'multinodular goitre' or multiple neoplasms of follicular cell origin with the morphology of those described here, particularly in young patients, should alert the pathologist and physician to the possibility of an inherited trait, with its implications for family screening. The tumours are usually benign and well demarcated but because of multicentricity and consequently increased risk of recurrence and/or progression to carcinoma, total thyroidectomy should be advocated.

Abstract
In this case-control study we describe how often thyroid cancers and occult cancers are diagnosed or not diagnosed by fine-needle aspiration (FNA) in patients with thyroid nodules and a family history of nonmedullary thyroid cancers (FNMTC). Our hypothesis is that patients with thyroid nodules and a family history of FNMTC seem to be similar to patients with thyroid nodules and a history of exposure to low-dose therapeutic radiation. Both have been reported to have multifocal thyroid neoplasms and malignant tumors are common. Cytological examination may therefore be less accurate. From 1979 to 1996, 27 patients from 24 families with FNMTC were examined histologically after a preoperative cytological examination in all of them. A positive cytology examination was defined when biopsy documented thyroid cancer. It was interpreted as a false-negative study when a benign diagnosis was made and thyroid cancer was present anywhere within the thyroid, including in areas sampled or not sampled by FNA and not palpable preoperatively. A randomized control group, matched for age and gender, contained 27 patients with papillary thyroid cancer without familial disease. In our study group, 25 patients were treated with total thyroidectomy, including 7 with neck dissection, and 2 by thyroid lobectomy. At final histological examination 17 of 27 patients (63%) in this study group had multiple nodules and 25 of 27 (92.6%) had thyroid cancer. Thyroid cancer was diagnosed by FNA in 22 of 25 patients (88%), with 3 (12%) false-negative biopsies due to sampling errors (thyroid cancer not in the index nodule), versus 1 (3.7%) false-negative biopsy in the control group. Two patients in the study group with benign nodules were accurately diagnosed. In patients with false-negative biopsies and a history of FNMTC, the cancer was situated in one or more small nodules. Only one cancer was occult (< 1.0 cm). One-third of the patients in our study group (33%) had a history of radiation; 44% of the irradiated group had a single nodule; 56% had multiple nodules. In the control group, 9 of 27 patients (33%) also had a history of radiation; 33% of the irradiated group had a single nodule, 67% had multiple nodules. In conclusion, the reliability of FNA in patients with FNMTC appears to be less accurate than it is for other patients because of the high incidence of multifocal thyroid cancer and coexistence of benign nodules. Patients with thyroid nodules and a family history of thyroid cancer are more likely to have thyroid cancer and because they also have more coexistent benign nodules, they must be followed closely or treated with total or near-total thyroidectomy.

Abstract
BACKGROUND AND OBJECTIVES When familial non-medullary thyroid cancer (FNMTC) develops with no obvious associated pathogenetic factor, an inherited predisposition may underlie the process. The present study was conducted because detailed pathological findings are lacking in most series of FNMTC. PATIENTS AND METHODS Thirteen families comprising 27 cases of FNMTC were included (1.8% of differentiated thyroid carcinoma). The family relationship (20 F, 7 M; age 46 +/- 16 years; mean +/- SD) was 'siblings' in eight families, 'parent and child' in four and 'aunt and niece' in one. Careful pathological review of the thyroid tumours (papillary/follicular: 25/2, size: 16 +/- 11 mm) was performed. RESULTS Initial staging according to extension was as follows: grade I (n = 16), II (n = 2), III (n = 6), IV (n = 3). Fourteen tumours were papillary microcarcinomas (size: 8 +/- 2 mm). No tumour phenotype that may be considered specific for FNMTC was found when considering either age, pathological findings or tumour aggressiveness. Although rare events were found in both relatives of some families suggesting a putative 'familial' phenotype of FNMTC, this may be fortuitous. CONCLUSION Micro familial non-medullary thyroid cancers are more common than previously reported and further studies are required to be able to distinguish this subgroup from sporadic papillary microcarcinomas. The careful pathological review of the familial non-medullary thyroid cancer in this study does not seem to point to a distinct subgroup of familial differentiated thyroid carcinoma although the data are intriguing. Genetic studies are now required to investigate this issue.

Abstract
Familial papillary thyroid carcinoma (fPTC) is an inherited tumor syndrome characterized by isolated papillary thyroid carcinoma (PTC) in affected subjects. Its etiology is unknown. Large multigeneration families with PTC are very rare, and therefore, modern genetic linkage studies have not been applied extensively to this disorder. Familial adenomatous polyposis coli (FAP) is an inherited tumor syndrome enriched in PTC. FAP is caused by germline mutations of the adenomatous polyposis coli (APC) gene that is located in the 5q21 region. It is not known if fPTC is a phenotypic variant of FAP, or if it is a genetically distinct disorder. We report a large 3-generation fPTC kindred and use linkage analysis to test the hypothesis that fPTC and FAP are genetically distinct. In this kindred there are 25 living informative subjects; 5 have PTC, and 1 is an obligate carrier. Inheritance is autosomal dominant with incomplete penetrance. There is vertical transmission, multifocal disease, an average age of onset of 36 years, and 1 subject has colon cancer. The probability is approximately 1 in 2 billion against the clustering of 5 sporadic PTC cases in this kindred. To test for linkage to the APC gene we used 2 highly polymorphic markers, D5S656 and D5S421, which are located within a maximum distance of 1.7 megabase (Mb) of the APC gene and within an estimated genetic region of less than 1 centimorgan (cM) from each other. After polymerase chain reaction (PCR) amplification 18 family members were genotyped. Construction and inspection of haplotypes showed that the affected subjects do not share the same allelic composition. Using a penetrance ratio of 75%, linkage was excluded at 2 cM and 3 cM on both sides of D5S656 and D5S421, respectively. The combined haplotype of these 2 markers provided an exclusion region of 4 cM. We conclude that fPTC is genetically distinct from FAP.

Abstract
BACKGROUND Familial, non-medullary thyroid carcinoma is clinically more aggressive than the sporadic form. We wanted to find out whether papillary thyroid microcarcinoma also occurs in a familial pattern, and, if so, to identify specific clinical and prognostic features. METHODS We reviewed the clinical records of 119 patients with papillary thyroid microcarcinoma. Familial occurrence, together with clinical presentation, surgical treatment, pathological characteristics, and follow-up were recorded. FINDINGS We identified a family history of thyroid carcinoma in seven patients. The tumour was multifocal in five patients, bilateral in three, and vascular invasion occurred in three of the seven patients. Lymph-node metastases were found in four patients. Three patients had a recurrence and one patient with pulmonary metastases died within 11 months. INTERPRETATION We identified familial occurrence in 5.9% of cases of papillary thyroid microcarcinoma. The unfavourable behaviour in the familial form of papillary thyroid microcarcinoma suggests that radical treatment and careful follow-up are warranted.

Abstract
It is well-known that medullary thyroid carcinoma occurs in a familial form as part of the multiple endocrine neoplasia (MEN) 2 syndromes. However, it is less well-recognized that nonmedullary thyroid carcinoma (NMTC) sometimes is familial. Arising from the thyroid epithelial cell, the NMTCs include papillary, follicular, and anaplastic thyroid carcinoma. Although most NMTC are sporadic, there is increasing evidence for a familial form. When inherited, NMTC is autosomal dominant with partial penetrance, and it is not associated consistently with other malignancies. The average age of onset is about 38 years, and in some cases, it may be more aggressive than sporadic PTC; up to 5% of subjects with NMTC have a family history positive for the same disorder. The etiologic gene(s) have not been identified, although positional cloning of these genes may be possible. The evidence for and characteristics of familial NMTC will be reviewed, and the clinical and research implications will be discussed.

Abstract
Familial nonmedullary thyroid cancer (FNMTC) is a clinical entity characterized by a phenotype more aggressive than that of its sporadic counterpart. Families with recurrence of nonmedullary thyroid cancer (NMTC) have been repeatedly reported in the literature, and epidemiological data show a very high relative risk for first-degree relatives of probands with thyroid cancer. The transmission of susceptibility to FNMTC is compatible with autosomal dominant inheritance with reduced penetrance, or with complex inheritance. Cases of benign thyroid disease are often found in FNMTC kindreds. We report both the identification of a new entity of FNMTC and the mapping of the responsible gene, named "TCO" (thyroid tumors with cell oxyphilia), in a French pedigree with multiple cases of multinodular goiter and NMTC. TCO was mapped to chromosome 19p13.2 by linkage analysis with a whole-genome panel of microsatellite markers. Interestingly, both the benign and malignant thyroid tumors in this family exhibit some extent of cell oxyphilia, which, until now, had not been described in the FNMTC. These findings suggest that the relatives of patients affected with sporadic NMTC with cell oxyphilia should be carefully investigated.

Abstract
Thyroid goiter is a common condition that is often associated with iodine deficiency. Familial forms of goiter in areas not known to feature iodine deficiency are much less common. We have performed a genomic search on a single large Canadian family with 18 cases of nontoxic multinodular goiter in which 2 individuals also had papillary lesions highly suggestive of papillary carcinoma. A locus on chromosome 14q (MNG1 [multinodular goiter 1]) has been identified, with a maximal two-point LOD score of 3.8 at D14S1030 and a multipoint LOD score of 4.88 at the same marker, defined by D14S1062 (upper boundary) and D14S267 (lower boundary). The gene encoding thyroid-stimulating hormone receptor (TSHR), which is located on chromosome 14q, is outside the linked region. To determine the role of this gene in familial nonmedullary thyroid cancer (NMTC), we studied 37 smaller pedigrees each containing at least two cases of NMTC. Analysis by both parametric and nonparametric methods indicates that only a very small proportion of familial NMTC (point estimate 0.001, support intervals 0-.6 under a dominant model) is attributable to MNG1.
