Abstract
In thyroid cancer, calcification is mainly present in classical papillary thyroid carcinoma (PTC) and in medullary thyroid carcinoma (MTC), despite being described in benign lesions and in other subtypes of thyroid carcinomas. Thyroid calcifications are classified according to their diameter and location. At ultrasonography, microcalcifications appear as hyperechoic spots ≤ 1 mm in diameter and can be named as stromal calcification, bone formation, or psammoma bodies (PBs), whereas calcifications > 1 mm are macrocalcifications. The mechanism of their formation is still poorly understood. Microcalcifications are generally accepted as a reliable indicator of malignancy as they mostly represent PBs. In order to progress in terms of the understanding of the mechanisms behind calcification occurring in thyroid tumors in general, and in PTC in particular, we decided to use histopathology as the basis of the possible cellular and molecular mechanisms of calcification formation in thyroid cancer. We explored the involvement of molecules such as runt-related transcription factor-2 (Runx-2), osteonectin/secreted protein acidic and rich in cysteine (SPARC), alkaline phosphatase (ALP), bone sialoprotein (BSP), and osteopontin (OPN) in the formation of calcification. The present review offers a novel insight into the mechanisms underlying the development of calcification in thyroid cancer.

Abstract
Background Although the study of calcium (Ca2+) is classically associated with excitable cells such as myocytes or neurons, the ubiquity of this essential element in all cellular processes has led to interest in other cell types. The importance of Ca2+ to apoptosis, cell signaling, and immune activation is of special import in cancer. Main Here we review the current understanding of Ca2+ in each of these processes vital to the initiation, spread, and drug resistance of malignancies. We describe the involvement of Ca2+, and Ca2+ related proteins in cell cycle checkpoints and Ca2+ dependent apoptosis and discuss their roles in cellular immortalization. The role of Ca2+ in inter-cellular communication is also discussed in relevance to tumor-stromal communication, angiogenesis, and tumor microinvasion. The role that Ca2+ plays in immune surveillance and evasion is also addressed. Finally, we discuss the possibility of targeting Ca2+ singling to address the most pressing topics of cancer treatment: metastatic disease and drug resistance. Conclusion This review discusses the current understanding of Ca2+ in cancer. By addressing Ca2+ facilitated angiogenesis, immune evasion, metastasis, and drug resistance, we anticipate future avenues for development of Ca2+ as a nexus of therapy.

Abstract
Although many clinical studies have found a correlation of SPARC expression with malignant progression and patient survival, the mechanisms for SPARC function in tumorigenesis and metastasis remain elusive. The activity of SPARC is context- and cell-type-dependent, which is highlighted by the fact that SPARC has shown seemingly contradictory effects on tumor progression in both clinical correlative studies and in animal models. The capacity of SPARC to dictate tumorigenic phenotype has been attributed to its effects on the bioavailability and signaling of integrins and growth factors/chemokines. These molecular pathways contribute to many physiological events affecting malignant progression, including extracellular matrix remodeling, angiogenesis, immune modulation and metastasis. Given that SPARC is credited with such varied activities, this review presents a comprehensive account of the divergent effects of SPARC in human cancers and mouse models, as well as a description of the potential mechanisms by which SPARC mediates these effects. We aim to provide insight into how a matricellular protein such as SPARC might generate paradoxical, yet relevant, tumor outcomes in order to unify an apparently incongruent collection of scientific literature.

Abstract
Tumor growth is essentially the result of an evolving cross-talk between malignant and surrounding stromal cells (fibroblasts, endothelial cells and inflammatory cells). This heterogeneous mass of extracellular matrix and intermingled cells interact through cell-cell and cell-matrix contacts. Malignant cells also secrete soluble proteins that reach neighbor stromal cells, forcing them to provide the soil on which they will grow and metastasize. Different studies including expression array analysis identified the matricellular protein SPARC as a marker of poor prognosis in different cancer types. Further evidence demonstrated that high SPARC levels are often associated with the most aggressive and highly metastatic tumors. Here we describe the most recent evidence that links SPARC with human cancer progression, the controversy regarding its role in certain human cancers and the physiological processes in which SPARC is involved: epithelial-mesenchymal transition, immune surveillance and angiogenesis. Its relevance as a potential target in cancer therapy is also discussed.

Abstract
Within the tumor microenvironment is a dynamic exchange between cancer cells and their surrounding stroma. This complex biologic system requires carefully designed models to understand the role of its stromal components in carcinogenesis, tumor progression, invasion, and metastasis. Secreted protein acidic and rich in cysteine (SPARC) is a prototypic matricellular protein at the center of this exchange. Two decades of basic science research combined with recent whole genome analyses indicate that SPARC is an important player in vertebrate evolution, normal development, and maintenance of normal tissue homeostasis. Therefore, SPARC might also play an important role in the tumor microenvironment. Clinical evidence indicates that SPARC expression correlates with tumor progression, but tightly controlled animal models have shown that the role of SPARC in tumor progression is dependent on tissue and tumor cell type. In this Prospectus, we review the current understanding of SPARC in the tumor microenvironment and discuss current and future investigations of SPARC and tumor-stromal interactions that require careful consideration of growth factors, cytokines, proteinases, and angiotropic factors that might influence SPARC activity and tumor progression.

Abstract
Selection of novel molecular markers is an important goal of cancer genomics studies. The aim of our analysis was to apply the multivariate bioinformatical tools to rank the genes - potential markers of papillary thyroid cancer (PTC) according to their diagnostic usefulness. We also assessed the accuracy of benign/malignant classification, based on gene expression profiling, for PTC. We analyzed a 180-array dataset (90 HG-U95A and 90 HG-U133A oligonucleotide arrays), which included a collection of 57 PTCs, 61 benign thyroid tumors, and 62 apparently normal tissues. Gene selection was carried out by the support vector machines method with bootstrapping, which allowed us 1) ranking the genes that were most important for classification quality and appeared most frequently in the classifiers (bootstrap-based feature ranking, BBFR); 2) ranking the samples, and thus detecting cases that were most difficult to classify (bootstrap-based outlier detection). The accuracy of PTC diagnosis was 98.5% for a 20-gene classifier, its 95% confidence interval (CI) was 95.9-100%, with the lower limit of CI exceeding 95% already for five genes. Only 5 of 180 samples (2.8%) were misclassified in more than 10% of bootstrap iterations. We specified 43 genes which are most suitable as molecular markers of PTC, among them some well-known PTC markers (MET, fibronectin 1, dipeptidylpeptidase 4, or adenosine A1 receptor) and potential new ones (UDP-galactose-4-epimerase, cadherin 16, gap junction protein 3, sushi, nidogen, and EGF-like domains 1, inhibitor of DNA binding 3, RUNX1, leiomodin 1, F-box protein 9, and tripartite motif-containing 58). The highest ranking gene, metallophosphoesterase domain-containing protein 2, achieved 96.7% of the maximum BBFR score.

Abstract
Microarray technology has become a powerful tool to analyze the gene expression of tens of thousands of genes simultaneously. Microarray-based gene expression profiles are available for malignant thyroid tumors (i.e., follicular thyroid carcinoma, and papillary thyroid carcinoma), and for benign thyroid tumors (such as autonomously functioning thyroid nodules and cold thyroid nodules). In general, the two main foci of microarray investigations are improved understanding of the pathophysiology/molecular etiology of thyroid neoplasia and the detection of genetic markers that could improve the differential diagnosis of thyroid tumors. Their results revealed new features, not known from one-gene studies. Simultaneously, the increasing number of microarray analyses of different thyroid pathologies raises the demand to efficiently compare the data. However, the use of different microarray platforms complicates cross-analysis. In addition, there are other important differences between these studies: 1) some studies use intraindividual comparisons, whereas other studies perform interindividual comparisons; 2) the reference tissue is defined as strictly nonnodular healthy tissue or also contains benign lesions such as goiter, follicular adenoma, and hyperplastic nodules in some studies; and 3) the widely used Affymetrix GeneChip platform comprises several GeneChip generations that are only partially compatible. Moreover, the different studies are characterized by strong differences in data analysis methods, which vary from simple empiric filters to sophisticated statistic algorithms. Therefore, this review summarizes and compares the different published reports in the context of their study design. It also illustrates perspectives and solutions for data set integration and meta-analysis, as well as the possibilities to combine array analysis with other genetic approaches.

Abstract
A 76-year-old woman with a history of total thyroidectomy for a thyroid carcinoma at the age of 63 was admitted to our hospital for the treatment of a renal rupture induced by a tumor of about 3 cm in diameter. High levels of blood thyroglobulin (Tg>1,000 ng/ml) led us to suspect a recurrence of thyroid carcinoma. Strong accumulation in whole-body 123I and 201Tl scintigraphy scans after the nephrectomy revealed tumors in the right lung and left thigh muscle measuring 5 cm and 9 cm in diameter, respectively. The tumors of the kidney and thigh muscle were pathologically diagnosed as poorly differentiated follicular thyroid carcinoma, and the lung tumor was also suggested to be a metastasis of the thyroid carcinoma based on the scintigraphy findings. We report this rare case of follicular thyroid carcinoma associated with metastases to the thigh muscle and kidney leading to a rupture 13 years after a total thyroidectomy. Care should be taken to determine whether unknown tumors are thyroid carcinoma metastases.

Abstract
An 84-year-old woman was admitted to our hospital for the examination and treatment of painful right thyroid swelling on August 2, 2002. Thyroid ultrasonography showed a mass of about 6 cm in diameter at the right thyroid lobe. Aspiration biopsy cytology (ABC) of her mass showed a thyroid carcinoma. Her neck mass was cold on (123)I scintigraphy and hot on both early- and delayed- phase (201)Tl scintigraphy. Whole body (67)Ga scintigraphy scan showed a strong hot accumulation in the area from the right thyroid lobe to the right lateral lobe. Multiple lung tumors were observed from chest computed tomography (CT) scans. She was diagnosed as having an anaplastic thyroid carcinoma with metastatic lung tumors. As her thyroid carcinoma was inoperable, percutaneous injection therapy of lipiodol and ethanol (lip-PEIT) against the primary thyroid carcinoma was performed twice a week. However, the thyroid carcinoma gradually enlarged and oppressed her trachea. Two months after the initiation of lip-PEIT, parathyroid hormone-related protein (PTHrP)-dependent hypercalcemia was diagnosed because serum levels of calcium, phosphate and intact-PTHrP were 2.72 mmol/l (10.9 mg/dl), 0.71 mmol/l (2.2 mg/dl), 3.2 pmol/l, respectively. The hypercalcemia was reduced by the use of pamidronate. After one week she died of an airway obstruction caused by the developing thyroid carcinoma. Carcinoma cells with a mixed papillary and squamoid pattern were positively stained immunohistochemically by anti-PTHrP(1-34) antisera. Herein, we report a rare autopsy case of a PTHrP-producing thyroid carcinoma.

Abstract
To find mRNAs whose expression differs between thyroid follicular adenomas and carcinomas, a high-throughput analysis of mRNAs in these two tumours was performed. This method, named high-throughput differential screening by serial analysis of gene expression (HDSS), combines a modified method of serial analysis of gene expression (SAGE) and real-time quantitative reverse transcription polymerase chain reaction (RT-PCR). A total of 40 candidate tag sequences that showed extremely different expression levels between a follicular carcinoma and a follicular adenoma in the SAGE analysis were analysed by real-time quantitative RT-PCR, using RNAs from an additional four typical follicular carcinomas and adenomas. One sequence tag that represents trefoil factor 3 (TFF3) mRNA showed a clear difference in its expression level between adenomas and carcinomas. The expression levels of TFF3 mRNA in 48 follicular adenomas and 29 follicular carcinomas were measured by real-time quantitative RT-PCR using a specific probe for TFF3. They were significantly decreased in follicular carcinomas, especially in widely invasive types and those with evident metastases. These results indicate that the decreased expression of TFF3 mRNA is a marker of follicular carcinomas, especially those with a high risk of invasion or metastasis.
