Abstract
INTRODUCTION The objective was to investigate the correlation between Epstein-Barr virus (EBV) and human papillomavirus (HPV) infection in the development of benign thyroid lesions. MATERIAL AND METHODS 29 cases of Hashimoto's thyroiditis (HT), 133 cases of thyroid adenoma, and 34 cases of HT with thyroid adenoma paraffin embedded tissue samples were used for EBV and HPV quantitative detection. RESULTS None of the tissue samples carried HPV DNA. In HT tissue samples, the positive rate of EBV was 55.2% (16/29). In thyroid adenoma tissue samples, the positive rate was 37.6% (50/133). In HT combined with thyroid adenoma tissue samples, the positive rate of EBV was 67.6% (23/34). There was no correlation between EBV infection and clinical features such as age and gender. CONCLUSION The occurrence and development of benign thyroid lesions are closely related to EBV infection. HT combined with thyroid adenoma may be more susceptible to EBV infection than simple HT and thyroid adenoma, which provides a new idea for the diagnosis and treatment of benign thyroid lesions.

Abstract
Healthcare settings, including nuclear medicine (NM) departments, promptly adjusted their standard operating procedures to cope with the unprecedented crisis caused by coronavirus disease 19 (COVID-19) pandemic. Nuclear thyroidology has adopted changes and predicated on a careful risk-benefit analysis, in order to prevent a potential spread of the virus while being at the same time effective, safe and preserving their quality of essential services. Since most thyroid nodules (TNs) are benign, and malignant neoplasms are characterized by an indolent natural history, it is generally safe to delay diagnostic and therapeutic procedures. In this respect, the main adjustments that nuclear thyroidology has adopted are summarized into the following: general workplace adjustments including remote work for NM staff; postponing appointments for consultation, diagnostic and therapeutic purposes and rescheduling based on individualized risk stratification; telemedicine; preparation for possible issues on radiopharmaceuticals synthesis and delivery; preventing measures and protocols to minimize or avoid potential COVID-19 infection of patients and medical staff. This document should be considered as updated guidance on how clinical management of TNs and thyroid cancer has been altered, remodeled and adapted to the new circumstances in the COVID-19 era, based on the rapidly growing volume of scientific information regarding the new coronavirus.

Abstract
Most patients with thyroid nodules and thyroid cancer (TC) referred for diagnostic work-up and treatment are not considered at higher risk of infection from SARS-CoV-2 compared to the general population. On the other hand, healthcare resources should be spared to the maximum extent possible during a pandemic. Indeed, while thyroid nodules are very common, only a small percentage are cancerous and, in turn, most thyroid cancers are indolent in nature. Accordingly, diagnostic work-up of thyroid nodules, thyroid surgery for either benign or malignant thyroid nodules and radioiodine treatment for differentiated thyroid cancers may be safely postponed during SARS-CoV-2 pandemic. Appropriate patient counselling, however, is mandatory and red flags should be carefully identified prompting immediate evaluation and treatment as appropriate. For these selected cases diagnostic work-up (e.g. ultrasound, scintigraphy, fine-needle aspiration), surgery and radioiodine therapy may proceed despite the threat of SARS-CoV-2 infection and COVID-19, after an individual risk-benefit analysis.

Abstract
Epidemiologic studies show an increased risk of mortality among hepatitis C virus (HCV)-infected individuals compared with uninfected individuals from hepatic and nonhepatic causes. This article reviews the biologic plausibility of and epidemiologic evidence for the association between HCV and five extrahepatic malignancies: cholangiocarcinoma (CCA), pancreatic adenocarcinoma, papillary thyroid cancer, oral squamous cell cancer, and renal/kidney cancer. There is sufficient evidence to suggest that HCV is associated with intrahepatic CCA. The evidence for the link between HCV and pancreatic adenocarcinoma, oral squamous cell cancer, and renal/kidney cancer is compelling but requires further study. Based on available studies, there is no significant association between HCV, extrahepatic CCA, and papillary thyroid cancer.

Abstract
Herpesviruses have been associated with various human malignancies and with thyroid autoimmunity. Aiming to investigate the presence of these viruses in thyroid nodules, we analyzed serum and thyroid tissue from 183 patients (83 benign and 100 malignant thyroid nodules). We also obtained 104 normal thyroid tissues extracted from the contralateral lobe of these patients. We used ELISA to screen the serology of all patients and a real-time quantitative PCR to analyze thyroid tissue viral load in antibody-positive patients. In addition, the presence of herpesviruses was tested by histological analysis in 20 EBV-positive tissues using the expression of LMP-1 by immunohistochemistry (IHC) and EBER by in situ hybridization (ISH). There was no evidence of HSV-2 or CMV DNA, but we found EBV DNA sequences in 29 (16%) thyroid tissue samples. We also found 7 positive EBV cases out of 104 normal tissues. Viral load was higher in tumors than in their respective normal tissues (p = 0.0002). ISH analysis revealed EBER expression in 11 out of 20 (52%) EBV-positive tissues, mostly in malignant cases (8/11, 73%). The presence of high EBV copy numbers in thyroid tumors and the expression of EBER only in malignant cases suggest an association between EBV and thyroid malignancies. However, we did not find any association between the presence of EBV and/or its viral load and any clinical or pathological tumor feature. Further studies aiming to clarify the mechanisms of EBV infection in thyroid cells are necessary to support a possible role in the development of thyroid cancer.

Abstract
The presence of viruses in the thyroid has been shown, but whether they are implicated in thyroid diseases or are only spectators is under investigation. The most important candidate viruses for autoimmune thyroid disorders (AITD) are hepatitis C virus (HCV) and human parvovirus B19 (or Erythrovirus B19 or EVB19). Retrospective and prospective case-control studies conducted on pathology slides showed (by PCR, in situ hybridization or immunohistochemistry) EVB19 was present in thyroid tissues of patients with autoimmune thyroiditis (AT), Graves' disease and thyroid cancer. Though AITD can be associated with acute EVB19 infection, it is not clear whether EVB19 could have a pathogenetic role in autoimmune thyroid diseases pathophysiology. Many studies have shown that frequently, patients with HCV chronic infection (CHC) show elevated serum anti-thyroperoxidase (TPOAb) and/or anti-thyroglobulin autoantibodies levels, ultrasonographic signs of chronic AT, and subclinical hypothyroidism. In patients with HCV-associated mixed cryoglobulinemia (MC + HCV), AITD were more prevalent with respect to controls, and also vs HCV patients without cryoglobulinemia. Papillary thyroid cancer was more prevalent in MC + HCV or CHC patients than in controls, especially in patients with AT. Recently it has been shown an elevated incidence of new cases of AT and thyroid dysfunction in MC patients. These results suggest an attentive monitoring of thyroid function and nodules in HCV patients with risk factors (female gender, a borderline high initial thyrotropin, TPOAb positivity, a hypoechoic and small thyroid) for the development of thyroid disorders.

Abstract
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human solid tumor and current treatments are ineffective in increasing patients' survival. Thus, the development of new therapeutic approaches for ATC is needed. We have previously shown that the oncolytic adenovirus dl922-947 induces ATC cell death in vitro and tumor regression in vivo. However, the impact of dl922-947 on the pro-tumorigenic ATC microenvironment is still unknown. Since viruses are able to regulate cytokine and chemokine production from infected cells, we sought to investigate whether dl922-947 virotherapy has such effect on ATC cells, thereby modulating ATC microenvironment. dl922-947 decreased IL-8/CXCL8 and MCP-1/CCL2 production by the ATC cell lines 8505-c and BHT101-5. These results correlated with dl922-947-mediated reduction of NF-κB p65 binding to IL8 promoter in 8505-c and BHT101-5 cells and CCL2 promoter in 8505-c cells. IL-8 stimulates cancer cell proliferation, survival and invasion, and also angiogenesis. dl922-947-mediated reduction of IL-8 impaired ATC cell motility in vitro and ATC-induced angiogenesis in vitro and in vivo. We also show that dl922-947-mediated reduction of the monocyte-attracting chemokine CCL2 decreased monocyte chemotaxis in vitro and tumor macrophage density in vivo. Interestingly, dl922-947 treatment induced the switch of tumor macrophages toward a pro-inflammatory M1 phenotype, likely by increasing the expression of the pro-inflammatory cytokine interferon-γ. Altogether, we demonstrate that dl922-947 treatment re-shape the pro-tumorigenic ATC microenvironment by modulating cancer-cell intrinsic factors and the immune response. An in-depth knowledge of dl922-947-mediated effects on ATC microenvironment may help to refine ATC virotherapy in the context of cancer immunotherapy.

Abstract
BACKGROUND The human pathogenic parvovirus B19 (B19) has recently been detected in papillary thyroid carcinoma (PTC) and Hashimoto's thyroiditis (HT) tissues at a high frequency in two studies of a Chinese cohort. We wanted to extend these data to include another cohort and expand the thyroid tumor tissue types assessed. In particular, we were interested to find whether B19 also infects anaplastic thyroid carcinoma (ATC), one of the most aggressive human cancers. METHODS Commercially available thyroid tumor tissue arrays were used to detect B19 capsid protein by immunohistochemistry in various types of thyroid tumors and disorders. The arrays were representative of the four main types of thyroid tumors, as well as other thyroid autoimmune disorders such as HT and Graves' disease, and adenomas, goiters, lymphomas, and normal thyroid tissue. In total, at least 12 different types of thyroid conditions as well as normal tissue were represented, many with multiple subjects. RESULTS Twenty-one of the 24 (88%) PTC tumors, 3 of the 3 ATC/undifferentiated tumors, and 3 of the 3 HT tissue samples were positive for B19 capsid protein by immunohistochemistry. The localization of the protein differed based on pathological disease type, with a nuclear to cytoplasmic shift seen from unaffected to tumor tissue. CONCLUSIONS We extend the data available on B19 detection in the thyroid to show a high correlation of virus in another cohort of PTC and HT at the protein level. We also show, for the first time, B19 infection of much more highly aggressive ATC/undifferentiated tumors. Nuclear to cytoplasmic shift in B19 protein in cancer tissue suggests a possible link between B19 and thyroid cancer pathogenesis/progression.

Abstract
BACKGROUND Viral infections are described as environmental factors that are implicated in various thyroid diseases. The role of enteroviruses (EV) in the pathogenesis of thyroid diseases has been suspected. Recently, we found that EV RNA could be detected in postoperative thyroid specimens. We decided to investigate the infection of a human thyroid cell line with coxsackievirus B4 (CVB4). METHODS The wild-type human thyroid carcinoma cells K1 were inoculated with CVB4E2 at 2.1 x 10(7) TCID50/mL. The titer of the virus progeny was determined every 3 days on HEp-2 cells. CVB replication at the molecular level was monitored by searching for intracellular viral genomes using reverse transcription (RT)-polymerase chain reaction (PCR). EV VP1 capsid protein was detected by indirect immunocytofluorescence staining. Cell viability was determined by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) absorbance, and the nuclear morphology was assessed by Hoechst Dye staining. RESULTS Infectivity assays with CVB4E2 revealed an increase in viral titers. Virus production decreased thereafter, but was not stopped by serial subculture for 24 days after infection. Detection of intracellular positive and negative viral RNA strands by RT-PCR was positive between days 1 and 14 postinfection (p.i.), and by semi-nested RT-PCR up to 24 days. K1 cell cultures infected with CVB4 were stained positively for EV VP1: the number of VP1-positive cells decreased rapidly within 6 days and remained low up to the end of culture. Compared with mock-infected cultures, viability in CVB4-infected cultures was around 100% up to 24 days. Cells with strongly fluorescent nuclei and/or fragmented nuclei were observed. CONCLUSION We demonstrate for the first time that CVB4 could replicate in thyroid cells and could persist, with predominance of viral negative RNA strands for up to 24 days p.i. without obvious cytopathic effect. Our results suggest that CVB4 may lead to thyroid cell apoptosis. Further studies are needed to determine whether CVB could play a role in thyroid pathologies.

Abstract
CONTEXT Hepatitis C virus (HCV) infection causes liver cancer and cirrhosis and may also increase the risk of other tumors, particularly hematopoietic malignancies and thyroid cancer. Previous studies have been too small to adequately assess these risks. OBJECTIVE To test the hypothesis that HCV infection is associated with increased risk for hematological malignancies, related lymphoproliferative disorders, and thyroid cancer. DESIGN, SETTING, AND PATIENTS A retrospective cohort study of users of US Veterans Affairs health care facilities from 1997-2004, which included 146,394 patients infected with HCV who had at least 2 visits with a diagnostic code for HCV infection, and 572,293 patients uninfected with HCV. To assemble the HCV-uninfected cohort, we randomly selected up to 4 patients per patient infected with HCV from all veterans who matched on age, sex, and baseline visit date and type (inpatient or outpatient). Individuals with human immunodeficiency virus were excluded. MAIN OUTCOME MEASURES Risks of hematopoietic malignancies, related lymphoproliferative precursor diseases, and thyroid cancer, adjusting for selection factors, race, era of military service, and use of medical services. RESULTS The mean (SD) age of the patients was 52 (8) years, and 97% were men. Risks for non-Hodgkin lymphoma (n = 1359), Waldenström macroglobulinemia (n = 165), and cryoglobulinemia (n = 551) were increased with HCV infection (adjusted hazard ratio [HR], 1.28; 95% confidence interval [CI], 1.12-1.45; adjusted HR, 2.76; 95% CI, 2.01-3.79; and adjusted HR, 3.98; 95% CI, 3.36-4.72; respectively). We found no significantly increased risk for other hematological malignancies. Although thyroiditis risk was slightly increased, risk for thyroid cancer (n = 320) was not (adjusted HR, 0.72; 95% CI, 0.52-0.99). Adjusted P values for non-Hodgkin lymphoma, Waldenström macroglobulinemia, cryoglobulinemia, and thyroiditis were all <.0038, the Bonferroni threshold for statistical significance considering multiple comparisons. CONCLUSIONS Hepatitis C virus infection confers a 20% to 30% increased risk of non-Hodgkin lymphoma overall, and a 3-fold higher risk of Waldenström macroglobulinemia, a low-grade lymphoma. Risks were also increased for cryoglobulinemia. These results support an etiological role for HCV in causing lymphoproliferation and causing non-Hodgkin lymphoma.

Abstract
Adenoviral gene therapy represents a novel approach for the treatment of aggressive thyroid carcinomas. Both coxsackie-adenovirus receptor (CAR) and integrins have been shown to be the major determinants for adenoviral infectivity in many types of cancer cells, yet conflicting results have been reported. In this report we examine these factors mediating adenoviral infection in thyroid cells and to evaluate CAR expression in various types of thyroid cancer. We found that neither expression levels of CAR nor integrins are solely predictive of adenoviral infectivity in thyroid cells. However, the absence of CAR was associated with poor adenoviral infectivity in immortalized rat FRTL-5 cells. Moreover, preincubation with alpha-CAR antibody decreased infectivity in FTC 238 cells, a human thyroid tumor line. These results indicate that CAR does play a role in adenoviral infection of thyroid cells. Immunohistochemical analysis revealed that CAR is expressed at the cell surface in the majority of malignant thyroid tumors. We further show that adenoviral infectivity in some thyroid cancer cells can be improved by poly-L-lysine. Our study warrants a functional method to evaluate adenoviral infectivity should be developed and instituted prior to clinical trials of adenoviral gene therapy in patients with advanced thyroid cancer.

Abstract
To study the etiologic factors of non-familial breast cancer, the polymerase chain reaction (PCR) and Southern hybridization were used to detect six viruses including human papillomavirus (HPV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV)-1, HSV-2, and human herpesvirus (HHV)-8 DNA in 69 patients with breast cancer and 60 specimens from non-cancerous or other individuals with thyroid tumors or fibroadenoma (non-breast cancer controls). Two specimens from patients with a familial history of breast cancer and five breast cancer specimens with negative results for beta-globin, which was used as internal control, were excluded from this study. Eight (12.9%) HSV-1, 28 (45.2%) EBV, 47 (75.8%) CMV, 8 (12.9%) HPV, and 28 (45.2%) HHV-8 positive samples out of the 62 breast cancer specimens were detected; no HSV-2 DNA was detected in any group. Among the viral gene-positive breast cancer samples, 12 (23.1%) were positive for 1 virus, 16 (30.8%) were positive for 2 viruses, 21 (40.4%) were positive for 3 viruses, and 3 (5.8%) were positive for 4 viruses. Among the viral gene-positive specimens of the control groups, only one virus, CMV, was found in the non-cancerous and thyroid tumor specimens, while multiple viruses were found in the fibroadenoma specimens. The viruses associated with breast cancer were HHV-8 > EBV (P <0.01). The viruses associated with fibroadenoma were HSV-1 and HHV-8 > EBV (P <0.01). The presence of more than one virus was found predominantly in breast cancer and exclusively found in fibroadenoma. CMV was the only virus associated with thyroid tumors.

Abstract
Thyroid cancers are of special interest in gene therapy, since it is possible to direct gene expression specifically to the thyroid derived cells by using promoters with limited expression, and secondly, because destruction of the normal tissue by introduction of a toxic gene would have no important adverse effect. A variety of methods for gene delivery are available. Adenovirus is a well studied and widely used vector and is useful for targeting genes because it infects many cell types, including differentiated thyroid cancer and medullary thyroid cancer cells. Strategies that have been employed successfully in animal models include adenoviral mediated expression of thymidine kinase under control of a thyroglobulin promoter, similarly expression of the cytokine IL-2, and perhaps most effectively, expression of IL-12. Combinations of vectors expressing thymidine kinase and IL-12 under control of a strong but non-tissue specific CMV promoter effectively destroy a model anaplastic thyroid tumor in Wistar rats. Replicating adenoviruses, in contrast to the non-replicating form commonly used, have also been used to infect tumor cells and express P-53 protein, leading to apoptosis of tumor cells. Medullary thyroid cancer provides a target much like differentiated thyroid cancer because it is possible to address gene expression specifically to the medullary thyroid cells by the use of a modified calcitonin promoter. Animal models of this tumor are available in a mouse and Wag/Rij rat model. In the latter system, treatment with adenoviruses expressing genes under control of the modified calcitonin promoter and expressing thymidine kinase or IL-12 leads to destruction of growing medullary thyroid cancer tumors, destroy distant tumors after injection in one tumor, and cause induction of long lasting immunity to subsequent tumor development in the animals. There are many ongoing studies of gene therapy in humans using various genes such as thymidine kinase, IL-2, and now IL-12. Although none of these trials to date shows complete eradication of metastatic tumors in humans, there are reports showing distinctly that the viral mediated gene therapy approach can effectively destroy human tumors after in vivo administration. Tumors that have been treated include melanomas, glioblastomas, breast tumors, and prostate carcinomas. In the latter studies, it has been possible to show objective responses documented by a fall in serum PSA levels of 50% or more that are sustained for prolonged periods. Gene therapy using the adenoviral vectors appears to be safe in studies reported so far. A problem is prior or induced immunity to adenoviral proteins, but direct injection of the vector into a tumor nodule largely circumvents this problem. New genes and new vectors under development will certainly lead to the established use of these methods in the therapy of human thyroid carcinomas in the near future.

Abstract
There have been few studies regarding cancer progression from differentiated thyroid carcinoma to the undifferentiated one. To examine the possible involvement of Epstein-Barr virus (EBV) in this progression, 10 papillary carcinomas and 11 undifferentiated carcinomas were subjected to mRNA in situ hybridization, indirect immunofluorescence staining, polymerase chain reaction (PCR), and reverse-transcriptase PCR. mRNA in situ hybridization using a BamHIW probe revealed signals in all of the examined samples, although the signal strength was weaker in the papillary carcinomas than in the undifferentiated carcinomas. EBV nuclear antigen-2 (EBNA2) in situ hybridization produced almost the same results; however, the signals were detected less frequently in the papillary carcinomas. Indirect immunofluorescence using anti-EBNA2, anti-latent membrane protein-1 (LMP1), and anti-BZLF1 antibodies also showed positive results with high frequency and with more prominent fluorescence in undifferentiated carcinomas than in papillary carcinomas. An examination of thyroid carcinoma cell lines also confirmed these findings. EBV infected all of the thyroid carcinomas irrespective of the degree of pathological differentiation. The expression of EBV, especially of EBNA2 and LMP1 (both of which are oncogene products of EBV), was stronger in the undifferentiated carcinomas than in the papillary carcinomas. These results suggest that increased expression of EBV may be involved in the progression of thyroid papillary carcinoma to undifferentiated carcinoma.

Abstract
Some studies report an increased risk of autoimmune thyroid disease in hepatitis C and B as well as in interferon therapy. Recently a new link between HCV and papillary thyroid cancer has been published. The mechanism responsible for the oncogenetic role of HCV is not well understood, but it involves immunity system and autoimmunity disorders. We designed a case-control study on HCV exposure. To assess the positivity to HCV ELISA test and polymerize chain reaction technique (PCR) were used. For statistical analysis an odds ratio and corresponding 95% confidence intervals were computed using unconditional multiple-logistic-regression models. Our findings show a statistically significant association between HCV and papillary thyroid cancer (OR = 3.3, 95% CI 1.5-7.4, p=0.003), overall in female gender (OR = 3.3, 95% CI 1.2-8.7, p=0.01) and in the > or =50 years age category the risk for thyroid cancer was confirmed by the OR = 3.2 (95% CI 1.3-7.9, p=0.01). Based on our study there is an association between HCV and thyroid cancer and it is more readily detectable in countries with a high prevalence of HCV.

Abstract
Abnormalities of thyroid function are associated with a number of systemic conditions, including patients infected with human immunodeficiency virus (HIV). Most patients with early HIV infection and a stable body weight have normal thyroid function. Subtle abnormalities of a number of thyroid function tests have been reported during the early asymptomatic phase of HIV disease. These include an inappropriately normal triiodothyronine (T(3)) and reduced reverse triiodothyronine (rT(3)), and increased thyroxine-binding globulin (TBG) levels. Opportunistic infections involving the thyroid gland, neoplasms such as lymphoma and Kaposi's sarcoma, and medications can alter the thyroid function in individuals with more advanced HIV infection. If thyroid dysfunction is diagnosed in an HIV-infected patient, it should be treated in the usual manner. However, high index of suspicion and caution in the interpretation of thyroid function tests in patients with HIV disease are needed for optimal diagnosis and treatment.

Abstract
Being one of the most lethal human neoplasms and refractory to such conventional treatment as chemo- and radiotherapy, anaplastic thyroid carcinoma is a prime target for innovative therapy. p53 gene inactivation is a constant feature of this neoplasia. Therefore, we evaluated a therapeutic approach based on an E1B 55-kDa gene-defective adenovirus (ONYX-015) that replicates only in cells with impaired p53 function and leads to cell death. Here we report that the ONYX-015 virus induces cell death in three human thyroid anaplastic carcinoma cell lines (ARO, FRO, and KAT-4). In addition, we found that the growth of xenograft tumors induced in athymic mice by the injection of ARO cells was drastically reduced by ONYX-015 treatment. The ONYX-015 virus worked synergistically with two antineoplastic drugs (doxorubicin and paclitaxel) in inducing ARO and KAT-4 cell death. These results suggest that ONYX-015 may be a valid tool in the treatment of the human thyroid anaplastic carcinoma.

Abstract
We have previously reported that the thyroid-targeted expression of the RET/PTC3 oncogene (Tg-RET/PTC3) in transgenic mice induces follicular hyperplasia with papillary architecture, resulting in a modest increase of the thyroid gland volume, followed by the appearance of papillary carcinomas in approximately 1-year-old animals. In order to analyze the genetic alterations that may cooperate with RET/PTC3 in the development or progression of thyroid tumors, we interbred Tg-RET/PTC3 mice with Tg-E7 transgenic mice, which express the E7 oncogene of the human papilloma virus 16 in thyroid cells. Tg-E7 mice develop large colloid goiters with small papillae and well-differentiated thyroid carcinomas in older animals. Here we show that thyroid lesions in Tg-RET/PTC3-Tg-E7 double transgenics were morphologically different from those occurring in Tg-RET/PTC3 mice, while they were virtually indistinguishable from those occurring in Tg-E7 mice. In addition, the coexpression of RET/PTC3 and E7 oncogenes neither enhanced the malignant phenotype nor reduced the latency period of thyroid lesions with respect to parental transgenic lines. We conclude that the coexpression of RET/PTC3 and E7 lacks any cooperative effect in the neoplastic transformation of thyroid cells and that the E7-induced thyroid phenotype is dominant with respect to the RET/PTC3 one.

Abstract
BACKGROUND/AIMS HCV is a RNA virus that cannot be integrated with the host genome; it can, however, exert its oncogenic potential indirectly by contributing to the modulatory effects of the host immune system, probably through a capacity to elude the immune system. We have carried out a case-controlled study on the different oncological pathologies which have, to date, been shown to have a relationship with HCV. METHODS We screened 495 patients with different types of cancer: 114 cases of liver cancer, 41 of multiple myeloma, 111 non-Hodgkin's lymphomas, 130 thyroid cancers, 63 cases of Hodgkin's disease. The controls were 226 patients with no history of cancer. The relationship between each cancer and HCV infection was assessed by means of odds ratios (OR) and corresponding 95% confidence intervals. RESULTS Risks were greater for liver cancer (OR=32.9 95% CI 16.5-65.4, p<0.0001), multiple myeloma (OR=4.5 95% CI 1.9-10.7, p=0.0004) and B-cell non-Hodgkin's lymphoma (OR=3.7 95% CI 1.9-7.4, p=0.0001). For Hodgkin's disease there was no significant association (p=0.3). An association between HCV and thyroid cancer was noted (OR=2.8 95% CI 1.2-6.3, p=0.01). CONCLUSION Our study is particularly important for public health since the high prevalence of HCV in the South of Italy gives reason to expect increases in not only liver cancer, but also tumors associated with the immune system and thyroid cancer in years to come.

Abstract
In vitro model cell systems are important tools for studying mechanisms of radiation-induced neoplastic transformation of human epithelial cells. In our study, the human thyroid epithelial cell line HTori-3 was analyzed cytogenetically following exposure to different doses of alpha- and gamma-irradiation and subsequent tumor formation in athymic nude mice. Combining results from G-banding, comparative genomic hybridization, and spectral karyotyping, chromosome abnormalities could be depicted in the parental line HTori-3 and in nine different HTori lines established from the developed tumors. A number of chromosomal aberrations were found to be characteristic for simian virus 40 immortalization and/or radiation-induced transformation of human thyroid epithelial cells. Common chromosomal changes in cell lines originating from different irradiation experiments were loss of 8q23 and 13cen-q21 as well as gain of 1q32-qter and 2q11.2-q14.1. By comparison of chromosomal aberrations in cell lines exhibiting a different tumorigenic behavior, cytogenetic markers important for the tumorigenic process were studied. It appeared that deletions on chromosomes 9q32-q34 and 7q21-q31 as well as an increased copy number of chromosome 20 were important for the tumorigenic phenotype. A comparative breakpoint analysis of the marker chromosomes found and those observed in radiation-induced childhood thyroid tumors from Belarus revealed a coincidence for a number of chromosome bands. Thus, the data support the usefulness of the established cell system as an in vitro model to study important steps during radiation-induced malignant transformation in human thyroid cells.

Abstract
In this article, we evaluated the feasibility of the restricted replication-competent adenoviruses for treatment of anaplastic thyroid carcinomas (ATCs), which are very aggressive and difficult to treat. Because ATCs very often harbor p53 mutations, we used wt-p53 as a regulatory factor to restrict virus replication and cytopathic effect to p53-mutated cells. The recently reported "gene inactivation strategy" using p53-regulated Cre/loxP system was employed; this system consists of two recombinant adenoviruses. One has an expression unit of the synthetic p53 - responsive promoter and the Cre recombinase gene (Axyp53RECre), and another contains two expression units; the first consists of E1A gene flanked by a pair of loxP sites downstream of the constitutive CAG promoter and the second E1B19K gene under the control of the CMV promoter (AdCALE1AL). We expected that coinfection of these two adenoviruses into the cells with wt-p53 would lead to expression of the Cre, which excises E1A gene and switches off E1A expression resulting in no virus replication, whereas in the cells with mutant p53 E1A could be expressed that leads to virus replication and cell lysis. Our in vitro data demonstrate that although infection of AdCALE1AL alone led to E1A expression, viral replication and cytolysis in all the thyroid cells examined irrespective of their p53 status, the double infection did so in FRO cells (p53-null ATC) but not in FRO cells stably expressing wt-p53 and normal thyroid cells with wt-p53. These data indicate that our double infection method may have a potential for treatment of ATC and probably also other p53-defective cancer cells.

Abstract
Lymphoma of thyroid is uncommon, and Epstein-Barr virus (EBV) is found in many lymphomas. We studied the clinicopathologic characteristics in Hong Kong Chinese and analyzed the presence of EBV in thyroid lymphomas by reviewing data collected during 3 decades. We studied EBV gene expression by in situ hybridization and immunohistochemistry. Primary thyroid lymphomas were found in 23 patients (diffuse large B-cell lymphoma, 18; marginal zone B-cell lymphoma, 4; plasmacytoma, 1), and secondary lymphomas were found in 9 patients (diffuse large B-cell lymphoma, 3; Burkitt lymphomas, 2; Burkitt-like lymphoma, 1; hairy cell leukemia, 1; nasal T-cell and natural killer cell lymphoma, 1; and intestinal T-cell lymphoma, 1). Primary thyroid lymphomas were large (mean, 7 cm), found commonly in older women, and often misdiagnosed as undifferentiated carcinomas. Fine-needle aspiration was not helpful for diagnosis. Fifteen patients had Hashimoto thyroiditis. A history of thyrotoxicosis was found in 3 patients, and coexistence of 3 diseases (papillary microcarcinomas, primary thyroid lymphoma, and Hashimoto thyroiditis) was found 4 patients. The 5-year survival rate for primary thyroid lymphoma was 53%. Combined surgery and radiotherapy seemed to be the best treatment. Secondary thyroid lymphomas often were asymptomatic. EBV messenger RNAs were detected in 1 primary and 1 secondary thyroid lymphoma. The EBV gene expression in primary thyroid lymphoma showed a type II latency pattern. Thyroid lymphomas in Chinese had important clinicopathologic features. EBV may have a role in a subset of cases.

Abstract
We report an unusual case of multifocal leiomyosarcoma involving the thyroid gland, liver, and right lung in a child with congenital immunodeficiency disease. The smooth muscle nature of these neoplasms was confirmed by immunohistochemistry and electron microscopic studies. In situ hybridization showed large amounts of Epstein-Barr virus messenger RNA within the tumor cells. Although Epstein-Barr virus-associated smooth muscle tumors have been reported in children with AIDS and after organ transplantation, we are unaware of any case report in congenital immunodeficiency disease.

Abstract
We investigated the p53 status and the ability of exogenous wildtype (wt) p53 to affect chemosensitivity in three anaplastic thyroid carcinoma cell lines (BHT-101, SW-1736, and KAT-4). All three cell lines had nonfunctional p53. Treatment with mitomycin C or adriamycin did not result in accumulation of p53 or induction of p21WAF1/CIP1 or Mdm-2 and did not cause Rb dephosphorylation. BHT-101 and KAT-4 cells had mutant p53. SW-1736 cells were functionally mutant because of marked down-regulation of wt p53 messenger ribonucleic acid, representing a novel mechanism of p53 dysfunction. Infection with a p53-expressing adenovirus (Ad-p53) induced high levels of p21 and Mdm-2 proteins. In BHT-101 cells, induction of p21 and Mdm-2 was evident 10 h after infection. In KAT-4 cells, induction of p21 and Mdm-2 was observed 1 day after infection, and continued to increase over the ensuing 24 h. SW-1736 cells demonstrated intermediate kinetics. Sensitivity to the cytotoxic effect of Ad-p53 paralleled the kinetics of p21/Mdm-2 induction. BHT-101 cells were most sensitive to killing by Ad-p53, with an IC50 of less than 2 multiplicity of infection; SW-1736 cells were intermediate in sensitivity; KAT-4 cells were resistant. All three cell lines became more sensitive to adriamycin after wt p53 expression, with a 10-fold decrease in IC50 values. The latter observation may make a combination of wt p53 and chemotherapeutic drugs an attractive modality for treating anaplastic thyroid cancer.

Abstract
Sequences of the SV40 virus, a virus of Asian macaques, have been found in human tumors, such as pleural mesotheliomas, ependimomas and choroid plexus tumors. Transgenic mice carrying the SV40 large T gene under the transcriptional control of the thyroglobulin gene promoter, develop thyroid dedifferentiation and follicular thyroid cell proliferation, leading to thyroid hyperplasia and adenocarcinomas. On these bases we investigated the presence of SV40 DNA sequences in 69 samples of papillary thyroid carcinomas (PTC) and in other thyroid and non-thyroid carcinomas, as well as in benign thyroid diseases. By Southern blot and PCR amplification followed by sequence analysis, we found the presence of SV40-related sequences integrated in the tumoral DNA of three cases of PTC. At least the 203 bp fragment of the aminoterminus of large T antigen, the 294 bp fragment of the VP1 gene and the 483 bp entire regulatory region were present in the tumoral DNA of these patients. SV40 sequences were not found in tissues other than PTC. Our results demonstrate that, in addition to previous findings in mesotheliomas and brain tumors, SV40 is somehow linked to papillary thyroid carcinoma. Although our data do not demonstrate a causative role in the development of PTC, this possibility must be considered and requires further studies.

Abstract
The causal role of Epstein-Barr virus (EBV) in the development of B-cell lymphoma, especially in immunocompromised individuals, has been suggested. The purpose of the present study was to evaluate an association of EBV with thyroid lymphoma (TL) and chronic lymphocytic thyroiditis (CLTH) which is known to play an important role in the development of TL. Thirty cases with TL and 28 with CLTH were studied for presence or absence of EBV genome in the lesions using the polymerase chain reaction (PCR) and the in situ hybridization method. EBV genomes were detected by PCR in one and two cases with CLTH and TL, respectively. Subtyping of EBV genome was possible in one TL case showing B-type in EBNA-2 coding region. In situ hybridization revealed positive signals in the nucleus of lymphoma cells, which also expressed latent membrane protein-1. The present findings indicate that activation of EBV in TL is not common.

Abstract
The oncogenic properties of the high risk human papillomaviruses (HPV) E7 protein are attributed to its interaction with the retinoblastoma susceptibility gene product RB1 and other related proteins. We report here the generation of a transgenic model expressing the E7 oncogene of HPV16 in thyroid follicular cells, under control of the bovine thyroglobulin gene promoter. Transgenics develop differentiated and functionally regulated thyroid goitres, due to thyroid cell proliferation and accumulation of colloid. On the background of this colloid goitre, the mice develop foci of more actively proliferating cells that become invasive and ultimately tend to loose their differentiation. Old mice display secondary tumour nodules that mimic the various histological aspects of the human differentiated thyroid cancers: the follicular and papillary carcinomas. The development of totally undifferentiated carcinoma is in contrast exceptional. We conclude that RB1, and/or related proteins, are responsible for the strict negative control of proliferation that characterizes the thyroid cell of the adult. Inactivation of these proteins results in a continuous growth of the thyroid, without affecting its differentiation, function and regulation. Given the high frequency of progression to highly malignant phenotypes, the retinoblastoma susceptibility and related genes are good candidates as targets for mutations or deletions in early steps of human thyroid carcinogenesis. The search for such mutations in human thyroid cancers will test if this hypothesis holds true.

Abstract
Epstein-Barr virus (EBV)-related mRNA, their products and apoptosis were investigated in 32 cases of malignant lymphoma of the thyroid (MLT) and 30 cases of Hashimoto's thyroiditis (HT) by in situ hybridization, immunohistochemistry and nick end labeling method on routinely processed tissue sections. In MLT, EBV-encoded small RNA (EBER) were detected in three cases, consisting of a follicular, predominantly large cell type (FL), a diffuse, large cell type (DL) and a large cell, immunoblastic type (IBL). In EBER-positive cases, IBL that was positive for T cell marker, exhibited neither BamHl H Left Frame 1 (BHLF1) transcript, EBV-encoded latent membrane protein (LMP) nor BamHl Z Left Frame 1 (BZLF1) gene product (ZEBRA), whereas both BHLF1 and ZEBRA were found in a small portion of the tumor cells in the FL and DL that expressed B cell marker and LMP. Apoptotic cells were observed in only a few lymphocytes in HT, and in a few non-neoplastic lymphocytes and various numbers of lymphoma cells in MLT. The apoptotic cell ratio of MLT tended to be higher in lower grade lymphomas. These results suggest that EBV may participate in the malignant transformation from HT to MLT.
