Abstract
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human cancers. Actually, ATC is refractory to conventional therapies, including surgery, chemotherapy, radiotherapy, and radioiodine ((131)I) therapy. Accordingly, genetic and molecular characterizations of ATC have been frequently and periodically reviewed in order to identify potential biological markers exploitable for target therapy. This review briefly focuses on main molecular events that characterize ATC and provides an update about preclinical studies. In addition, the overexpression of transferrin receptor 1 (TfR1/CD71) by neoplastic cells of ATC is emphasized in that it could represent a potential therapeutic target. In this regard, new therapeutic approaches based on the use of monoclonal or recombinant antibodies, or transferrin-gallium-TfR1/CD71 molecular complexes, or lastly small interfering RNAs (siRNAs) are proposed.

Abstract
BACKGROUND On occasion, a microscopic anaplastic focus (MAF) is discovered in papillary thyroid carcinoma (PTC). The relevance of MAF has not been well studied with regard to its clinical implications. MAF is defined as the microscopic presence of focally dedifferentiated follicular cells within the PTC. METHODS A total of 3,606 patients who underwent primary thyroid surgery between 1995 and 2007 were selected from the database of Seoul National University Hospital. Patients were divided into 3 groups based on histology: PTC without MAF (3,574 patients), PTC with MAF (13 patients), and anaplastic thyroid carcinoma (19 patients). RESULTS Mean ± standard deviation age was 48 ± 12 years (range, 17-83) in the PTC without MAF group, 57 ± 14 years (range, 29-76) in the PTC with MAF group, and 64 ± 14 years (range, 24-86) in the ATC group (P < .001). Mean tumor sizes were 1.2 ± 0.9 cm (range, 0.5-13), 2.1 ± 1.2 cm (range, 0.7-5), and 3.7 ± 1.4 cm (range, 0.4-6), respectively (P < .001). The median follow-up was 32 months. The cause-specific survival at 5 years was 98% in the PTC without MAF group, 64% in the PTC with MAF group, and 11% in the ATC group (P < .001). Multivariate analysis showed that MAF was a prognostic factor for the outcome of PTC patients (hazard ratio, 12.9; 95% confidence interval, 3.1-54.1; P < .001). CONCLUSION MAF negatively influenced the prognosis of patients with PTC. Further research and the design of more aggressive treatment strategies for MAF might be helpful for patients with PTC.

Abstract
PURPOSE Anaplastic thyroid cancer (ATC) is a lethal disease causing a global disproportionate number of thyroid cancer-related deaths. The American Thyroid Association (ATA) has recently produced clear and comprehensive guidelines to assist physicians treating ATC. METHODS The recent ATA guideline publication was reviewed. A systematic review of studies indexed in Medline and Pubmed was also undertaken using search terms relevant to ATC. RESULTS Patients with ATC have a median survival of 5 months and less than 20% survive 1 year. Early tumor dissemination results in 20-50% percent of patients having distant metastases and 90% having adjacent tissue invasion on presentation. This highlights the necessity for effective combined therapy. Stage IVA/ IVB, resectable disease may benefit from a multimodal (surgery, IMRT for loco regional control, and systemic therapy) approach. However, a majority of patients present with unresectable locoregional disease. Early palliative care involvement is inclusive of life-prolonging therapies. ATC management demands rapid, complex and integrated multidisciplinary decision making. CONCLUSION In this article we discuss the multidisciplinary strategies that exist to optimize the management of these patients in accordance with the recent guidelines from The American Thyroid Association.

Abstract
OBJECTIVE In this study, we present our experience with aggressive surgical treatment in selected patients with anaplastic thyroid cancer with extrathyroidal extension. STUDY DESIGN Case series with chart review. SETTING Tertiary care referral center. SUBJECTS AND METHODS Retrospective chart review of all patients with anaplastic thyroid cancer surgically treated by the senior author from January 1998 to July 2012. RESULTS A total of 38 cases of anaplastic thyroid cancer were treated (21 male and 17 female). The mean age was 64.5 years. Twenty-two patients were considered surgically unresectable (18 had distant metastases and 4 had extrathyroidal extension of cancer lateral to carotid arteries) and underwent biopsy with or without tracheostomy. The remaining 16 patients underwent surgical resection with curative intent. Fourteen of these patients underwent postoperative radiation therapy. None of these 16 patients developed local recurrence. Six developed distant metastasis at an average follow-up of 3.2 months, 1 died of an unrelated myocardial infarction at 3 months, 2 were lost to follow-up, and 7 remain disease free with an average follow-up of 4.8 years (range, 9 months to 8 years). Of those patients who underwent complete surgical resection followed by postoperative radiation, 7 of 14 (50%) are still alive, with a mean follow-up of 4.8 years. CONCLUSION Selected patients with anaplastic thyroid cancer with extrathyroidal extension (stage IVB) who show no distant metastases by computed tomography or positron emission tomography scans and who do not have tumor extending lateral to the carotid arteries are candidates for complete surgical resection.

Abstract
BACKGROUND Anaplastic thyroid cancer (ATC) is a rare but highly lethal form of thyroid cancer. Rapid evaluation and establishment of treatment goals are imperative for optimum patient management and require a multidisciplinary team approach. Here we present guidelines for the management of ATC. The development of these guidelines was supported by the American Thyroid Association (ATA), which requested the authors, members the ATA Taskforce for ATC, to independently develop guidelines for ATC. METHODS Relevant literature was reviewed, including serial PubMed searches supplemented with additional articles. The quality and strength of recommendations were adapted from the Clinical Guidelines Committee of the American College of Physicians, which in turn was developed by the Grading of Recommendations Assessment, Development and Evaluation workshop. RESULTS The guidelines include the diagnosis, initial evaluation, establishment of treatment goals, approaches to locoregional disease (surgery, radiotherapy, systemic therapy, supportive care during active therapy), approaches to advanced/metastatic disease, palliative care options, surveillance and long-term monitoring, and ethical issues including end of life. The guidelines include 65 recommendations. CONCLUSIONS These are the first comprehensive guidelines for ATC and provide recommendations for management of this extremely aggressive malignancy. Patients with stage IVA/IVB resectable disease have the best prognosis, particularly if a multimodal approach (surgery, radiation, systemic therapy) is used, and some stage IVB unresectable patients may respond to aggressive therapy. Patients with stage IVC disease should be considered for a clinical trial or hospice/palliative care, depending upon their preference.

Abstract
A 95-year-old woman had been treated over the past 8 years for progressive dysphagia. When her condition worsened, blood tests revealed the presence of leucocytosis and eosinophilia in the absence of anaemia or thrombocytopenia. Within 11 days of diagnosis, the patient died of respiratory failure. Necropsy showed normal thyroid tissue and an absence of infectious disease. However, an upper mediastinal tumour was found and was histopathologically diagnosed as a neoplastic transformation of the ectopic thyroid. Only 1% of endothoracic goitres present as ectopic or autonomous goitre with no parenchymal or vascular connection to the thyroid gland. This case represents a very rare situation in which a leukemoid reaction and peripheral hypereosinophilia were observed as a manifestation of an anaplastic thyroid carcinoma in an ectopic mass.

Abstract
Warthin tumor-like papillary thyroid carcinoma is an uncommon variant of papillary thyroid carcinoma. We report a rare case of Warthin tumor-like variant of papillary thyroid carcinoma with a dedifferentiated component consisting of a solid tumor area composed of neoplastic cells with a spindle to tall cell morphology associated with marked nuclear pleomorphism, atypical mitoses, and foci of necrosis. Although our patient presented with a locally aggressive disease (T3 N1b Mo), she is disease-free without radioiodine therapy after a 23-month follow-up period. We emphasize that Warthin tumor-like papillary thyroid carcinoma, like other morphological variants of papillary carcinoma, may occasionally undergo dedifferentiation. As this component may be only focally detectable, we suggest an extensive sampling of all large-sized (>3 cm) papillary thyroid carcinoma. Recognition of any dedifferentiated component in a Warthin tumor-like papillary thyroid carcinoma should be reported, including its percentage, because it may reflect a more aggressive clinical course.

Abstract
The aim of this study was to gain better insight into molecular changes which reflect disturbances in the balance between proliferation and apoptosis during progression of thyroid malignancy from papillary microcarcinoma (PMC) via clinically manifest papillary carcinoma (PTC) to anaplastic carcinoma (ATC). The apoptosis related molecules (Bcl-2, Bax) and proliferation related marker (PCNA) were analysed immunohistochemically in 120 archival cases comprising PMC (n=34), PTC (n=52) and ATC (n=34). In addition, in situ apoptotic cell death was analysed by the TUNEL method. The average Bcl-2 staining score did not differ between PMC and PTC (p>0.05), but was significantly lower in ATC (p<0.05).The Bax score was higher in PTCs and ATCs than in PMCs (p<0.05). Due to these changes, the Bcl-2/Bax ratio showed a marked decrease from PMC to ATC (p<0.05), while proliferation activity increased significantly from PTC to ATC (p<0.05). Despite high Bax expression, the rate of apoptotic cell death was low in the investigated carcinomas, especially in ATC, i.e. the increase in proliferative activity was not counterbalanced with appropriate cell death. Differences were found in the expression of apoptotic molecules (Bcl-2 and Bax), their ratio (Bcl-2 /Bax) and in the rate of apoptotic cell death and proliferative activity between PMC, PTC and ATC, indicating that disturbances in the balance between apoptosis and proliferation, in favour of the latter, occur gradually during the progression of malignancy in thyroid tumours.

Abstract
Background We present the case of a patient who presented with anaplastic thyroid carcinoma with a solitary large liver metastasis. Hepatic metastases are extremely rare in anaplastic thyroid carcinoma. Case presentation We report the case of a 78-year old Greek man who presented with voice hoarseness, dyspnoea and a large mass on the anterior surface of the cervical region (neck), as well as constitutional symptoms such as anorexia, weight loss and malaise. On physical examination, the thyroid was hard and tender on palpation and a liver mass was palpable. Routine biochemistry yielded normal results except increased C-reactive protein, alkaline phosphatase and γ-glutaryl transferase. Other biochemical tests including tumor markers, thyroid hormones, antithyroid antibodies, hepatitis B and hepatitis C antibodies were negative. Imaging methods revealed enlargement of the left thyroid lobe extending to the anterior mediastinum and compressing the trachea, metastatic bilateral pulmonary lesions and a large, nodular, contrast-enhanced mass-occupying lesion in the right hepatic lobe. The findings of fine-needle aspiration biopsy of the thyroid were consistent with anaplastic carcinoma. Liver biopsy showed infiltrations by poorly differentiated anaplastic cells, few of which were slightly positive for thyroglobulin. These findings were suggestive of a hepatic metastasis originating from anaplastic thyroid carcinoma. During his hospitalization, the patient suffered progressive obstruction of the trachea due to rapid increase of the thyroid gland mass. The tumor was considered unresectable due to its advanced stage, as well as the presence of extrathyroid metastatic lesions. The patient was irradiated on cervical region (neck) and upper mediastinum with a daily dose of 300 cGy for 10 days which resulted in mild improvement of obstructive phenomena. However, his clinical condition deteriorated rapidly and he died within a few days. Conclusion Solitary, large hepatic metastasis may constitute a rare complication in anaplastic thyroid carcinoma.

Abstract
Anaplastic thyroid carcinoma is a rare and highly malignant disease. Usually, this type of tumor is irresectable, and almost all patients die within 1 year after diagnosis. We present a case of anaplastic thyroid carcinoma with rhabdomyoblastic differentiation and good therapeutic outcome. A 76-year-old female was referred to our hospital with a growing, painless neck mass which existed for 3 months. Biopsy of the mass showed microscopically and immunohistochemically a follicular (Hürthle cell) carcinoma of the thyroid, dedifferentiated to an anaplastic carcinoma with divergent differentiation along rhabdomyoblastic cell lines. The patient underwent a total thyroidectomy with additional lymph node dissection, followed by two episodes of 150 mC I(131) therapy and external radiotherapy. After a follow-up of 3 years, the patient still remains in a good condition without any signs of recurrent disease. Other cases of rhabdomyoblastic and rhabdoid anaplastic thyroid carcinomas have been described. Both types of carcinoma are associated with an aggressive clinical course. In our case, the patient is still alive without evidence of disease 3 years after primary therapy. The good clinical outcome of our patient suggests that surgical resection, radiotherapy, and I-131 ablation therapy with curative intent seems to be an adequate treatment option in patients with anaplastic thyroid carcinoma with rhabdoid and rhabdomyoblastic differentiation.

Abstract
OBJECTIVES Apolipoprotein E (Apo E) has been known to play a role in cholesterol transport and metabolism. However, recently the relationship between Apo E and carcinoma progression has been investigated. In this study, we investigated Apo E expression in thyroid carcinoma at both the protein and molecular levels. METHODS We investigated Apo E expression at the protein and molecular level in 124 thyroid neoplasms. RESULTS In RT-PCR and in situ hybridization, the Apo E mRNA expression level was very low in papillary and follicular carcinomas as well as normal thyroid, but was dramatically elevated in anaplastic carcinoma. In an immunohistochemical study, 32 of 33 anaplastic carcinomas (97.0%) showed high levels of Apo E expression, but this phenomenon was seen only in 1 of 51 papillary carcinomas (2.0%). None of the follicular carcinomas or adenomas showed high levels of Apo E expression. CONCLUSIONS These findings suggest that Apo E is one of the typical biological characteristics of anaplastic thyroid carcinoma.

Abstract
Thyroid cancer is an uncommon malignancy that accounts for roughly 1% of all new cancers. Although anaplastic lesions constitute fewer than 5% of thyroid cancers, they represent over half of thyroid cancer-related deaths. The relative rarity of anaplastic thyroid cancer, its aggressive nature, and its rapidly fatal course have contributed to the difficulty in developing effective treatment for this disease. Radiation, chemotherapy, and surgery are rarely curative, but combinations of these modalities appear to offer greater benefit than any single treatment. New treatment modalities are desperately required, and promising molecular-based therapies are being investigated.

Abstract
A radiation etiology is well known in thyroid carcinogenesis. RET oncogene rearrangement is the most common oncogenic alteration in Chernobyl-related papillary thyroid cancer (PTC). To find the characteristic alteration associated with RET rearrangements in radiation-induced thyroid cancers, we analyzed the RET oncogene by fluorescence in situ hybridization. The fluorescence in situ hybridization technique has the possibility of detecting RET rearrangements at a single-cell level regardless of the specific fusion partner involved and directly reveals RET copy number on a per-cell basis. Our study demonstrated RET amplification in all 3 cases of radiation-associated thyroid cancers but not in sporadic well-differentiated PTC (n = 11). Furthermore, RET amplification was observed in all 6 cases of sporadic anaplastic thyroid cancers (ATCs). The frequency of RET amplification-positive cells was higher in ATC (7.2%-24.1%) than in PTC (1.5%-2.7%). The highest frequency of RET amplification-positive cells was observed among ATC cases with a strong p53 immunoreactivity. In conclusion, we found RET amplification, which is a rare oncogenic aberration, in thyroid cancer. This report is the first one to suggest the presence of RET amplification in PTC and ATC. RET amplification was correlated with radiation-associated, high-grade malignant potency, and p53 accumulation, suggesting genomic instability. RET amplification might be induced by a high level of genomic instability in connection with progression of thyroid carcinogenesis and, subsequently, be associated with radiation-induced and/or high-grade malignant cases.

Abstract
BACKGROUND Anaplastic thyroid carcinoma (ATC), although rare, is one of the most aggressive human cancers, and patients with ATC have extremely poor prognoses despite various therapeutic measures. We wished to determine the prognostic factors of survival and effect of treatment on survival rate in patients with ATC. METHODS We retrospectively reviewed the medical records of the 121 patients (41 men and 80 women) diagnosed with ATC from January 1995 to June 2004 at 5 major referral centers in Korea. RESULTS Mean patient age at diagnosis was 64 +/- 11 years (range, 17-84 years). Of the 121 patients, 11 (9%) had intrathyroidal tumors, 69 (57%) had extrathyroidal tumors or lymph node involvement, 29 (24%) had distant metastases, and 12 had no data about staging (9%). The mean tumor diameter was 5.5 +/- 2.5 cm (range, 0.5-17.0 cm). At a median follow-up of 41 months (range, 26-122 months), 8 patients were alive. Median survival time was 5.1 months. The disease-specific survival rates were 42% at 6 months, 16% at 12 months, and 9% at 24 months. Sixteen patients (13%) received only supportive care, 25 (21%) received surgery alone, 20 (16%) received radiation treatment or chemotherapy without surgery, and 60 (50%) received surgery plus radiation treatment or chemotherapy. Multivariate analysis showed that age less than 60 years, tumor size less than 7 cm, and lesser extent of disease were independent predictors of lower disease-specific mortality. CONCLUSIONS Long-term survival is possible for ATC patients less than 60 years old and with small localized tumors. Although aggressive multimodal therapy, including surgery, radiation treatment, and chemotherapy, was not significantly associated with improved survival, we advocate aggressive multimodal therapy in selected ATC patients with good prognostic factors.

Abstract
AIMS Tumour protein p53-induced nuclear protein 1 (TP531NP1) is a stress-induced protein and plays a role in cell cycle arrest and p53-mediated apoptosis. In this study, we investigated TP531NP1 expression in human thyroid neoplasms. METHODS We immunohistochemically investigated TP531NP1 in 197 cases of various thyroid neoplasms. RESULTS Normal follicles did not express TP531NP1. All 39 (20 minimally invasive and 19 widely invasive) follicular carcinomas and 20 adenomas were negative for or expressed only low levels of TP531NP1 except for one widely invasive follicular carcinoma. Of 100 papillary carcinomas, only four (4%) expressed high levels of TP531NP1, and the remaining 96 (96%) were classified into the low group. There were no significant relationships between TP531NP1 expression and clinicopathological features of papillary carcinoma. However, 36 of the 38 (94.7%) anaplastic carcinomas expressed high levels of TP531NP1 and the incidence was significantly higher (p<0.0001) than that in other neoplasms. CONCLUSIONS These findings suggest that TP531NP1 plays a significant role in the progression of anaplastic carcinoma or contributes to anaplastic transformation from papillary or follicular carcinoma, which is in sharp contrast to findings in previous in vitro and in vivo studies.

Abstract
Radioiodine remnant ablation (RRA) was developed in the 1960s to "complete a thyroidectomy" in the initial management of papillary and follicular thyroid cancer. By the 1990s, it was claimed that RRA diminished recurrence rates in follicular cell-derived cancer (FCDC) patients and decreased the cause-specific mortality (CSM) in patients more than 40 years old at initial surgery. The international trend for the past decade has been towards routine RRA in most FCDC patients. Clinical guidelines have been produced by many societies, promoting such an aggressive stance. Since 1997, many papers have reported improved outcome in FCDC, when patients were subjected to RRA after bilateral lobar resection. However, during the same time-period, it has been recognized that most FCDC patients are truly at "low-risk" of developing life-threatening recurrences. Accordingly, it has been suggested that rational therapy selection should lead to restricting aggressive therapy to those "high-risk" FCDC patients, more predisposed to CSM. To date, no prospective controlled trials exist. Presently available outcome data is based on single institutional or multicenter retrospective studies. This article summarizes the available relevant reported data, and concludes that a selective use of RRA in the postoperative management of FCDC patients is rational, and should actually be encouraged.

Abstract
AIMS p73, a homologue of p53, is known as a negative regulator of tumour progression. However, delta Np73, an isoform of p73 lacking the NH2-terminal transactivation domain plays an oncogenic role by interfering with the activity of p53 and TA (full-length transactivating isoforms) p73. In this study, we investigated the expression of delta Np73 in human thyroid neoplasms originating from follicular cells. METHODS We immunohistochemically investigated delta Np73 expression in 223 thyroid neoplasms. Delta Np73 expression level was evaluated as the sum of positivity score and intensity score. RESULTS Normal follicular cells did not express delta Np73, but 27.3% of follicular adenoma, 85.4% of follicular carcinoma, 99.2% of papillary carcinoma, and 95.7% of anaplastic carcinoma were positive for the transcript. Delta Np73 expression level did not differ between widely invasive and minimally invasive follicular carcinomas. In papillary carcinoma, the level was inversely linked to tumour size, extrathyroid extension, and clinically apparent metastasis. Furthermore, in anaplastic carcinoma, delta Np73 expression level was significantly lower than that in papillary carcinoma. CONCLUSIONS Our findings indicate that delta Np73 plays a role predominantly in the early phase of papillary carcinoma progression.

Abstract
BACKGROUND Anaplastic thyroid carcinoma (ATC) is one of the most aggressive solid tumors known to affect humans and carries a dismal prognosis. Our primary aim was to review its epidemiology, biology, risk factors, and prognostic indicators. We also reviewed the individual and combined roles of surgery, radiotherapy, chemotherapy, and newer therapeutic options in the management of ATC. METHODS An extensive literature review was conducted to include all published reports on ATC. The changing trends in the management of anaplastic thyroid cancer were analyzed to summarize the current practice of management of ATC. RESULTS Although ATC is rare, there has been a decline in its incidence worldwide. ATC accounts for more than half of the 1200 deaths per year attributed to thyroid cancer. Long-term survivors are rare, with >75% and 50% of patients harboring cervical nodal disease and metastatic disease, respectively, at presentation. ATC can arise de novo or from preexisting well-differentiated thyroid cancer. Surgical management has shifted from tracheostomy only for palliation to curative resection when possible. Tracheostomy is performed for impending obstruction rather than for prophylaxis. Radiotherapy has evolved from postoperative administration only to preoperative treatment, combining preoperative and postoperative treatment and using higher doses, along with hyperfractionating and accelerating dose schedules. Chemotherapy has changed from monotherapy to combination therapy, and newer drugs such as paclitaxel show promise. Similarly, novel angiogenesis-inhibiting agents are currently being used, with early reports of some benefit. CONCLUSIONS Despite multimodality approaches, ATC still carries a dismal prognosis. This should provoke innovative strategies beyond conventional methods to tackle this uniformly lethal disease.

Abstract
UDP-N-acetylglucosamine:alpha-mannoside beta-1,6-N-acetylglucosaminyltransferase (GnT-V) catalyzes the formation of beta-1-6 GlcNAc branches on asparagine-linked oligosaccharides, which is directly linked to tumorigenesis. Our recent studies indicate that the secretion of matriptase from cancer cells is increased via the action of GnT-V, as evidenced by the fact that matriptase-bearing beta-1-6 GlcNAc branching is dramatically inhibited. In this study, we report on an investigation of the expression of GnT-V and matriptase in thyroid neoplasm tissues to determine the clinical significance on the co-expression of these two proteins in thyroid cancer. Although neither GnT-V nor matriptase was expressed in normal thyroid tissue, positive staining for matriptase and GnT-V was observed in 52/68 and 66/68 cases of papillary carcinoma, 3/23 and 10/23 cases of follicular carcinoma, 5/13 and 9/13 cases of follicular adenoma, and 11/28 and 6/28 cases of anaplastic carcinoma, respectively. Immunohistochemistry, as well as western blotting, showed that the expression of matriptase paralleled the expression to GnT-V. However, the expression of matriptase mRNA was not correlated with its protein levels, suggesting that the enhancement in matriptase expression could be regulated by a posttranslational modification such as glycosylation through GnT-V-mediated glycosylation. In papillary carcinoma, the levels of expression of both GnT-V and matriptase were significantly higher in tumors 1 cm or less in size (microcarcinoma) and in those without poorly differentiated lesions, and the two proteins were significantly correlated. In contrast, the prognosis of thyroid carcinoma after surgery was neither correlated with the expression GnT-V nor matriptase, because the levels of their expression were quite low in anaplastic (undifferentiated) carcinomas. These results suggest that prolonged stabilization of matriptase is stabilized by GnT-V-mediated glycosylation in vivo, thus extending its halftime and permitting it to play role in the early phases of papillary carcinoma, but not in its later phase progression.

Abstract
Well-differentiated thyroid carcinoma (TC), as papillary and follicular carcinoma, usually follows a relatively benign course after total thyroidectomy and thyroid remnant ablation with 131I. In contrast, anaplastic TC or undifferentiated TC, also derived from the thyroid follicular epithelium, refers to one of the more aggressive human malignancies, which have lost most or all characteristics of the tissue from which it originated. Rapid tumor growth presages early mortality unless combined therapy is aggressively pursued. Definitive curative approach does not exist for most patients. The best approach is still aggressive surgery combined with the associated use of new chemotherapies associated with local external beam radiotherapy.

Abstract
S100A9, a calcium-binding protein, is associated with myeloid cell differentiation and is expressed in some adenocarcinomas as well as in squamous epithelia and squamous cell carcinoma. In this study, we immunohistochemically investigated S100A9 expression in thyroid neoplasms. S100A9 was absent in normal follicles, follicular adenoma, and follicular and papillary carcinomas with conventional growth structures. In lesions showing a solid, trabecular, or scirrhous growth pattern, S100A9 immunoreacitivity was occasionally observed. One (5.9%) of the 17 follicular carcinomas and three (7.8%) of the 38 papillary carcinomas were regarded as positive for S100A9, but the positive cell areas always accounted for 5% or less. However, S100A9 was positive in all 19 undifferentiated carcinomas examined. Among them, the positive cell area was greater than 5% in 16 (84.2%), and greater than 25% in six (31.6%) cases. It is therefore suggested that S100A4 protein plays an important role in thyroid carcinoma dedifferentiation, and can be considered a novel characteristic of undifferentiated carcinoma.

Abstract
BACKGROUND Anaplastic thyroid carcinoma (ATC) is the most lethal form of thyroid neoplasia and represents the end stage of thyroid tumor progression. In the current study, genetic alterations in a panel of ATC were profiled to determine the origins of ATC. METHODS Eight ATC were analyzed for BRAF mutation at codon 599 by using mutant-allele-specific polymerase chain reaction (PCR) and DNA sequencing of the PCR-amplified exon 15. RAS mutation (HRAS, KRAS, and NRAS) at codons 12, 13, and 61 was analyzed by direct sequencing of PCR-amplified exons 1 and 2 of the RAS gene. RET/PTC rearrangements and p53 mutation were monitored by immunohistochemical (IHC) staining by anti-RET antibodies and an anti-p53 mAb, respectively. RESULTS BRAF was mutated in 5 of the 8 ATCs tested. Histologic examination revealed that 4 of these 5 BRAF-mutated ATCs contained a PTC component, suggesting that they may be derived from BRAF-mutated PTC. Of the 3 ATCs with wild-type BRAF, 2 had spindle cell features; one had follicular neoplastic characteristics mixed with papillary structures. Analysis of RAS mutation revealed only an HRAS mutation at codon 11, due to the transversion of GCC to TCC in one ATC with wild-type BRAF. This leads to the substitution of valine to serine. IHC analysis of RET/PTC rearrangements revealed no positive staining of RET in any of 8 ATCs, suggesting that these ATCs are not derived from RET/PTC- rearranged PTC. In contrast, IHC analysis of p53 mutation revealed that p53 was detected in the nuclei of 5 of 5 BRAF-mutated ATCs and 2 of 3 ATCs with wild-type BRAF. p53 staining was present only in anaplastic thyroid tumor cells but not in neighboring papillary thyroid tumor cells. CONCLUSIONS These results suggest that many ATCs with papillary components are derived from BRAF-mutated PTC, because of the addition of p53 mutation.

Abstract
Thyroid cancer is a relatively common and frequently curable malignant neoplasm, accounting for nearly 2% of all new cancers diagnosed annually in the United States. The diagnostic and management options have evolved considerably in the past decade, and a current understanding of these trends in the standard of care have assumed an important consideration in the practices of head and neck surgeons and endocrinologists alike. We sought to review the epidemiology and pathology of the several types of thyroid cancer and to present our evidence-based management algorithm. Every effort was made to offer alternative treatment strategies and supporting data where available. In addition to reviewing well-established approaches to diagnosis and management, emphasis is placed on newer techniques, including minimally invasive thyroidectomy, molecular detection of disease propensity, and the use of recombinant thyrotropin prior to radioiodine ablation.

Abstract
Tob, a member of the Tob/BTG family, is a novel anti-proliferative protein, but it becomes inactive when phosphorylated. In this study, we investigated whether Tob is phosphorylated and inactive in various thyroid neoplasms in order to elucidate how this event plays a role in their progression. Tob phosphorylation was only occasionally seen in normal follicular cells. A high level of Tob phosphorylation was observed in 42.1% of follicular adenoma, 14.3% of follicular carcinoma. In papillary carcinoma, the Tob phosphorylation level was elevated more frequently than that in follicular carcinoma, and 39.7% of specimens were classified in the high group. Tob phosphorylation level in papillary carcinoma was directly linked to tumor size, lymph node metastasis, extrathyroid extension and the presence of poorly differentiated lesion. In anaplastic carcinoma, surprisingly, Tob phosphorylation was not observed in any cases, but the deficiency of Tob expression was also observed in all these cases. These results suggest that (1) Tob phosphorylation contributes to the progression of papillary carcinoma especially in the later phase through cancellation of its anti-proliferative function, and (2) the deficiency of Tob expression is attributable to the lack of Tob phosphorylation in anaplastic carcinoma.

Abstract
AIMS S100 calcium-binding proteins are known to play multiple roles in carcinoma development. In this study, we focused on two kinds of these proteins, S100A2 and S100A6, and investigated their expression in thyroid neoplasms. METHODS AND RESULTS We investigated S100A2 and S100A6 expression in 141 thyroid neoplasms by immunohistochemistry. S100A2 was not expressed in normal follicles or follicular tumours, with one exception. Although 89.5% of papillary carcinoma were positive for S100A2, the expression was heterogeneous except in two cases. In anaplastic carcinoma, 78.5% of cases expressed S100A2 diffusely, while the remaining cases were negative. In normal follicles, S100A6 expression was always low, while 8.3% of follicular adenomas and 39.5% of follicular carcinomas showed increased expression. In papillary carcinomas, S100A6 expression was increased in 75% of cases, but in anaplastic carcinomas it was decreased, with only 14.3% showing high expression. CONCLUSIONS The expression patterns of S100A2 and S100A6 in thyroid neoplasms are unique compared with those of other carcinomas, suggesting that: (i) S100A2 and S100A6 contribute to certain events in papillary carcinoma progression, and (ii) S100A2 expression is one of the biological characteristics of anaplastic carcinoma.

Abstract
AIMS To review the outcome of patients diagnosed with anaplastic thyroid carcinoma in British Columbia between January 1985 and December 1999. MATERIALS AND METHODS Seventy-five patients were identified. Survival curves were calculated using Kaplan-Meier estimates, and the charts of the 62 patients referred to a British Columbia Cancer Agency (BCCA) facility were reviewed. RESULTS All cases: 51 out of 75 patients (68%) were women; median age of all patients was 74 years. The overall- and cancer-specific 5-year survival rates for the whole group were 5%. non-referred cases: nine out of 13 patients were women; median age at diagnosis 84 years. Eleven of the 13 patients died within 1 month of diagnosis. Referred cases: 42 out of 62 patients were women; median age 72 years; median survival 5.1 months; 1-year survival 19%. Forty-eight patients presented with tumours that extended through the thyroid capsule, 10 presented with distant metastases. Four patients had a total thyroidectomy, nine a partial thyroidectomy, and 49 a biopsy only. Fifty-seven patients received radiotherapy, nine of these had concurrent chemotherapy: Thirty-three patients received less than 40 Gy and 24 patients received 40 Gy or more. Median survival was longer (9 vs 3 months) in patients receiving 40 Gy or more; this group included four patients who had prolonged survival. CONCLUSION Long-term, disease-free survival was achieved in a few patients who were able to receive high-dose radiotherapy, preferably after adequate surgery.

Abstract
BACKGROUND Anaplastic thyroid carcinoma (ATC) is rare but is one of the most aggressive human malignancies. Several prognostic factors have been observed in patients with ATC, and some experts advocate aggressive multimodal therapy in selected patients. However, it is unclear whether such an approach significantly improves survival. The authors analyzed prognostic factors and treatment outcomes in patients with ATC reported in the National Cancer Institute's Surveillance, Epidemiology, and End Results data base. METHODS The cohort consisted of 516 patients with ATC reported to 12 population-based cancer registries between 1973 and 2000. Demographic, pathologic, and treatment data were used for univariate and multivariate survival analyses. RESULTS The mean patient age at diagnosis was 71.3 years, and there were 171 men and 345 women. Eight percent of patients had intrathyroidal tumors, 38% had extrathyroidal tumors and/or lymph node invasion, and 43% of patients had distant metastasis. The average tumor size was 6.4 cm (range, 1-15 cm). Sixty-four percent of patients underwent surgical resection of their primary tumor, and 63% received external beam radiotherapy. The overall cause-specific mortality rate was 68.4% at 6 months and 80.7% at 12 months. Univariate analysis showed that age < 60 years, female gender, intrathyroidal tumor, external beam radiotherapy, surgical resection, and combined surgical resection of tumor and radiotherapy were associated with a lower cause-specific mortality. On multivariate analysis, only age < 60 years, an intrathyroidal tumor, and the combined use of surgical and external beam radiation therapy were identified as independent predictors of lower cause-specific mortality. CONCLUSIONS Although most patients with ATC had an extremely poor prognosis, patients < 60 years old with intrathyroidal tumors survived longer. Surgical resection with external beam radiotherapy for ATC was associated with lower cause-specific mortality.

Abstract
OBJECTIVES S100A4 is a calcium-binding protein related to the metastatic potential of carcinoma. In order to elucidate its contribution to the progression of thyroid carcinoma, we investigated S100A4 expression in various thyroid neoplasms. METHODS We immunohistochemically examined S100A4 expression in 195 cases of thyroid neoplasms. RESULTS Although S100A4 was absent in normal follicular cells and follicular adenoma, S100A4 was positive in all 115 cases of papillary carcinoma examined, including 58 microcarcinomas. However, a significant relationship could not be established between S100A4 expression and clinicopathological features of papillary carcinoma. In follicular carcinoma, the widely invasive type expressed S100A4 more frequently than the minimally invasive type (p = 0.0028). In anaplastic carcinoma, S100A4 was expressed in 61.9% of cases, but the incidence was significantly lower (p < 0.0001) than that in papillary carcinoma. CONCLUSIONS These findings suggest that (1) S100A4 plays a constitutive role in papillary carcinoma and (2) S100A4 may be a useful marker for early the detection of this carcinoma.

Abstract
AIMS To investigate tie-1 expression in human thyroid neoplasms. Recent studies have demonstrated that receptor-type tyrosine kinases (RTKs) contribute to carcinoma progression. Tie-1 is one of the RTKs and plays a role in angiogenesis, although its pathophysiological significance in human carcinoma is still to be elucidated. METHODS AND RESULTS Immunohistochemical expression of tie-1 was studied in various thyroid neoplasms. Tie-1 immunoreactivity was only occasionally observed in normal follicular cells. In papillary carcinoma, tie-1 was classified as positive in carcinoma cells in 55.7% of the cases and was more frequently expressed in those of smaller size with an absence of a poorly differentiated lesion. In contrast, tie-1 was positive in only 8.3% of anaplastic carcinoma and no cases of follicular carcinoma or adenoma were positive. CONCLUSIONS These results suggest that tie-1 has a role in thyroid tumorigenesis, especially in the early phase of papillary carcinoma, but it is not important in the progression of anaplastic carcinoma or follicular tumour.

Abstract
Papillary carcinomas of the thyroid are the most common malignant growth affecting the thyroid, currently representing 60–65 per cent of malignant thyroid neoplasm. Although the etiology of this neoplasm is unknown, they are thought to be related to neck irradiation, adenoma transformation, and Hashimoto thyroiditis. Papillary carcinomas are usually purely papillary but occasionally have areas of histologically different neoplasm, most commonly follicular. Overall, these carcinomas represent an indolent group of neoplasm and have an excellent prognosis. The occurrence of an anaplastic area in a papillary carcinoma represents the dedifferentiation of the primary neoplasm. This is an extremely rare occurrence and is considered to have negative prognostic significance. The purpose of this presentation is to discuss an unusual clinical case of a coexisting anaplastic and papillary carcinoma of the thyroid, diagnosed by fine needle aspiration (FNA) analysis presenting in a 67-year-old African-American woman. Evaluation and treatment will be discussed.

Abstract
Anaplastic carcinoma of the thyroid gland (ACT) is a highly malignant tumor that is almost invariably associated with a fatal outcome. It demonstrates a variety of peculiar histological features, with squamoid, giant cell and spindle cell growth patterns. The spindle cell variant of ACT is usually indistinguishable from a true sarcoma and it can simulate fibrosarcoma, malignant fibrous histiocytoma (MFH), hemangiopericytoma and angiosarcoma or rhabdomyosarcoma. Although a rhabdomyosarcomatous appearance has sometimes been mentioned in the literature, true skeletal muscle differentiation has never been consistently proved. We report two cases of ACT with rhabdomyosarcomatous differentiation, as demonstrated by means of immunohistochemistry and electron microscopy. Both cases disclosed a very similar histological appearance, with a main population of small, pleomorphic, round-to-oval cells arranged in a storiform pattern, admixed with scattered pleomorphic giant cells, an image similar to that of the usual type of MFH. Stains for epithelial markers showed only few, scattered, weakly positive cells. Thyroglobulin and calcitonin were negative in tumor cells in both cases. On the contrary, positivity to vimentin was strong and generalized. Immunomarkers of muscular differentiation showed a consistent positivity. At the ultrastructural level, the cells disclosed the same spindle and pleomorphic morphology, with large, bizarre nuclei and cytoplasm with abundant mitochondria, rough endoplasmic reticulum, secretory granules and lipid droplets. There were also cells with wide cytoplasm filled with filamentous material, either of actin or myosin, as well as Z-band material. In conclusion, the cases reported here show a clear-cut rhabdomyosarcomatous differentiation of ACT, confirmed both immunohistochemically and ultrastructurally, a feature not previously reported in the literature. These findings may contribute to the broadening of the differentiation spectrum of this unusual neoplasm.

Abstract
Polo-like kinase 1 (PLK1) is one of the serine threonine kinases that contributes to cell mitosis and is regarded as a marker of cellular proliferation. However, its protein expression in human carcinoma has not been studied in depth. We investigated PLK1 expression in various thyroid neoplasms in order to elucidate its physiological significance in thyroid carcinoma. Normal follicular cells only occasionally expressed PLK1. In follicular tumours and anaplastic carcinoma, PLK1 overexpression was not a common event and only 5.9% of follicular adenoma, 7.1% of follicular carcinoma, and 11.8% of anaplastic carcinoma overexpressed this protein. However, 43.7% of papillary carcinoma overexpressed PLK1. Polo-like kinase 1 overexpression was more frequently observed in smaller papillary carcinoma lesions, and 62.5% of microcarcinoma (ranging from 4 mm to 1.0 cm) and even 66.7% of incidental carcinoma (less than 4 mm) overexpressed it, whereas this phenomenon could only be seen in 20.0% of lesions larger than 4.0 cm. Furthermore, PLK1 overexpression was not related to cell-proliferating activity evaluated by Ki-67 labelling index, but it was inversely linked to UICC stage, extrathyroidal invasion, and the presence of poorly differentiated lesion as proposed by Sakamoto et al. These findings strongly suggest that, unlike other carcinomas previously studied, PLK1 does not act as a cell cycle regulator but plays a constitutive role in papillary carcinoma especially in the early phase, and may contribute to the malignant transformation of this carcinoma.

Abstract
OBJECTIVES p8 protein has mitogenic activity and is linked to the development of pancreatic carcinoma. However, little is known about the expression and physiological significance of this protein in other human carcinomas. METHODS In this study, we immunohistochemically investigated p8 expression in thyroid neoplasms as well as in the normal thyroid gland. RESULTS p8 was expressed in normal follicular cells, but no normal thyroid was regarded as overexpressing p8. On the other hand, 44.3% of papillary carcinoma overexpressed p8 and the incidence was directly linked to the tumor size (p=0.0340) and lymph node metastasis (p=0.0145). In follicular tumors, the incidence of p8 overexpression did not depend on histological type. In anaplastic (undifferentiated) carcinoma, p8 was overexpressed only in 5.0%, which was significantly lower than in papillary (p=0.0006) and follicular carcinomas (p=0.0049). In normal follicules and follicular tumors, p8 was localized mainly in the nucleus except for two adenomas. On the other hand, p8 localization was more cytoplasmic in papillary carcinoma larger than 1.0 cm (p=0.0186) and with a poorly differentiated lesion (p=0.0313). CONCLUSIONS These results suggest that the overexpression and cytoplasmic localization of p8 protein may reflect disease progression of papillary carcinoma, whereas this protein plays little part in thyroid carcinoma after anaplastic transformation.

Abstract
Maspin belongs to the serpin superfamily and has been identified as a tumor suppressor because it inhibits cell motility, invasion, and angiogenesis. However, its physiological activity in carcinoma tissues seems to differ according to the origin of the carcinoma. In this study, we investigated maspin expression in thyroid neoplasms originating in follicular cells by means of immunohistochemistry. Neither normal follicular cells nor stromal cells expressed maspin. Follicular adenomas were all negative for maspin, but 12.5% of follicular carcinomas and 30.5% of papillary carcinomas were positive for it. However, the staining pattern was only focal in all positive specimens except for one and maspin-expressing cells were present mainly at the edge of carcinoma nests. Widely invasive follicular carcinomas tended to be more frequently positive for maspin than minimally invasive ones. In papillary carcinoma, maspin expression was directly linked to stage, tumor size, and extrathyroidal invasion. Papillary and follicular carcinomas involving lesions with solid, trabecular, or scirrhous growth patterns (poorly differentiated carcinoma as designated by Sakamoto et al.) expressed maspin in significantly higher incidence than those with pure papillary or follicular patterns. Furthermore, 48.2% of anaplastic (undifferentiated) carcinomas diffusely expressed maspin, and the rest were completely negative. These findings indicate that, in contrast to other carcinomas, maspin expression is directly associated with the biological aggressiveness of thyroid carcinoma. Further studies regarding the function of maspin in this carcinoma are required.

Abstract
KAI1 is a metastasis suppressor gene located on human chromosome 11p11.2. Previous studies have shown that the down-regulation of KAI1 mRNA and decreased expression of its gene product are significantly linked to carcinoma progression, including metastatic ability. In this study, we investigated KAI1 protein expression in thyroid neoplasms. KAI1 overexpression was observed in 64.0% of papillary carcinoma cases, and the incidence was significantly higher than in cases of follicular carcinoma (20.0%) (p = 0.0001). In papillary carcinomas, decreased KAI1 expression was frequently observed in cases invading beyond the thyroid capsule (p = 0.001), as well as in lymph node metastases (p = 0.0047) and poorly differentiated lesions (p = 0.0299). Furthermore, in anaplastic carcinoma, the incidence of KAI1 overexpression was lower than in papillary carcinoma (p < 0.0001), and only 4.2% of the cases overexpressed this gene. These results suggest that KAI1 down-regulation is significantly related to the progression of papillary carcinoma, including lymph node metastasis, and its anaplastic transformation.

Abstract
Previous studies have demonstrated that terminal fucosylation is associated with the biological aggressiveness of carcinomas, but the significance of core fucosylation (alpha1,6-fucosylation) through alpha1,6-fucosyltransferase (FUT8) has not been studied in depth. Herein, we investigated the expression of alpha1,6-fucosyltransferase (FUT8) in 133 cases of thyroid carcinomas using an immunohistochemical approach. The expression of FUT8 was quite low in normal follicules. A high expression of FUT8 was observed in 33.3% of papillary carcinoma and the incidence was directly linked to tumor size and lymph node metastasis. In contrast, this phenomenon was less frequently observed in follicular carcinoma and anaplastic (undifferentiated) carcinoma. These results suggest that FUT8 expression may be a key factor in the progression of thyroid papillary carcinomas, but not follicular carcinomas, and decreases in FUT8 expression might be linked to anaplastic transformation.

Abstract
Activating point mutations of the BRAF gene have been recently reported in papillary thyroid carcinomas. In this study, we analyzed 320 thyroid tumors and six anaplastic carcinoma cell lines and detected BRAF mutations in 45 (38%) papillary carcinomas, two (13%) poorly-differentiated carcinomas, three (10%) anaplastic carcinomas, and five (83%) thyroid anaplastic carcinoma cell lines but not in follicular, Hürthle cell, and medullary carcinomas, follicular and Hürthle cell adenomas, or benign hyperplastic nodules. All mutations involved a T-->A transversion at nucleotide 1796. In papillary carcinomas, BRAF mutations were associated with older age, classic papillary carcinoma or tall cell variant histology, extrathyroidal extension, and more frequent presentation at stages III and IV. All BRAF-positive poorly differentiated and anaplastic carcinomas contained areas of preexisting papillary carcinoma, and mutation was present in both the well-differentiated and dedifferentiated components. These data indicate that BRAF mutations are restricted to papillary carcinomas and poorly differentiated and anaplastic carcinomas arising from papillary carcinomas. They are associated with distinct phenotypical and biological properties of papillary carcinomas and may participate in progression to poorly differentiated and anaplastic carcinomas.
