Abstract
Thyroid cancer is the most frequent endocrine malignancy, with more than 500,000 cases per year worldwide. Differentiated thyroid cancers are the most common forms with best prognosis, while poorly/undifferentiated ones are rare (2% of all thyroid cancer), aggressive, frequently metastasize and have a worse prognosis. For aggressive, metastatic and advanced thyroid cancer novel antitumor molecules are urgently needed and phytochemical products can be a rational and extensive source, since secondary plant metabolites can guarantee the necessary biochemical variability for therapeutic purpose. Among bioactive molecules that present biological activity on thyroid cancer, resveratrol, curcumin, isoflavones, glucosinolates are the most common and used in experimental model. Most of them have been studied both in vitro and in vivo on this cancer, but rarely in clinical trial. This review summarizes phytochemicals, phytotherapeutics and plant derived compounds used in thyroid cancer.

Is a simplified TNM staging system more clinically relevant than the American Joint Committee on Cancer system for the follicular variant of papillary thyroid cancer? ANNALS OF TRANSLATIONAL MEDICINE 2020; 8:463.

Abstract
Background Despite the recent release of the 8th edition of the American Joint Committee on Cancer (AJCC) staging manual, risk stratification for the follicular variant of papillary thyroid cancer (FVPTC), which is the second common variant of papillary thyroid carcinoma (PTC) after classical PTC, remains controversial. This study aimed to develop a more accurate and relevant staging system specifically for FVPTC. Methods Patients with FVPTC who were included in the Surveillance, Epidemiology, and End Results (SEER) open database between 2010 and 2015 were divided into 47 groups according to their TNM classifications and age. Subsequently, these 47 groups were categorized into appropriate stages based on Kaplan-Meier survival curves, mortality analyses, a Cox proportional hazards model, and clinical considerations. Results Our retrospective analysis of 17,628 cases yielded the following new staging classification: stage I, defined as age <55 years and any T/N/M or age ≥55 years and T1-3/any N/M0 (n=17,427, 98.85%); stage II, age ≥55 and T4/any N/M0 or age ≥55 and any T/N0/M1 (n=173, 0.99%); and stage III, age ≥55 and any T/N1/M1 (n=28, 0.16%). The overall mortality rates per 1,000-person-years were 4.135 [95% confidence interval (CI): 3.653–4.681], 71.193 (95% CI: 51.354–98.697), and 199.744 (95% CI: 115.983–343.997) for our new stages I, II, and III, respectively. The hazard ratios for the new stages II and III (reference: stage I) were 5.081 (95% CI: 3.110–8.301) and 21.690 (95% CI: 11.402–41.258), respectively. Conclusions Compared to the 8th edition of the AJCC staging system, our newly proposed system provided more accurate risk stratification for patients with FVPTC, as demonstrated by actual survival and mortality outcomes. This new model may thus help guide more personalized treatment for these patients.

First ever case report of co-occurrence of hobnail variant of papillary thyroid carcinoma and intrathyroid parathyroid adenoma in the same thyroid lobe. Int J Surg Case Rep 2020; 70:40-52. [PMID: 32408235 PMCID: PMC7218145 DOI: 10.1016/j.ijscr.2020.04.025] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/16/2020] [Accepted: 04/18/2020] [Indexed: 01/24/2023] Open
Abstract
First reported case of hobnail variant of papillary thyroid cancer and Intrathyroid parathyroid adenoma occurring within same thyroid lobe. Next-generation sequencing of the mutation spectrum of hobnail variant of papillary thyroid cancer showed BRAFV600E mutation. Studies that define other molecular abnormalities may be useful as therapeutic targets.
Introduction The hobnail variant of papillary thyroid cancer (PTC) is rare. Intrathyroid parathyroid adenoma (ITPA) is also rare. Co-ocurrence of PTC and ITPA in the same thyroid lobe is extremely rare. Likewise, primary hyperparathyroidism with such non-medullary thyroid carcinoma is rare. The specific molecular profile of hobnail PTC (HPTC) is different from the classic, poorly differentiated and anaplastic variants and may contribute to its aggressive behavior. HPTC’s genetic profile remains unclear. Presentation of case A 61-year-old woman presented to our endocrine clinic with generalized aches, bone pain, polyuria, and right neck swelling of a few months’ duration. Laboratory findings revealed hypercalcemia and hyperparathyroidism. Ultrasound of the neck showed 4.6 cm complex nodule within the right thyroid lobe. Sestamibi scan suggested parathyroid adenoma in the right thyroid lobe. Fine-needle aspiration (FNA) revealed atypical follicular lesion of undetermined significance. She underwent right lobectomy, which normalized the intraoperative intact parathyroid hormone levels. Final pathology with immunohistochemical stains demonstrated HPTC and IPTA (2 cm each). Next-generation sequencing investigated the mutation spectrum of HPTC and detected BRAFV600E mutation. Conclusions A parathyroid adenoma should not exclude the diagnosis of thyroid carcinoma. Thyroid evaluation is needed for patients with primary hyperparathyroidism to prevent missing concurrent thyroid cancers. Cytomorphologic features to distinguish thyroid from parathyroid cells on FNA cytology must be considered. Immunohistochemical stains are important. BRAFV600E is the most common mutation in HPTC. This is possibly the first reported case of HPTC and ITPA co-occurring within the same thyroid lobe. Studies that define other molecular abnormalities may be useful as therapeutic targets.

Abstract
Background: The increased incidence of primary papillary thyroid microcarcinoma (PTMC) has led to increased research in the field of nonsurgical therapeutic options for those who refuse surgery or are at high risk for surgery. The study aimed at comprehensively evaluating the efficacy and safety of thermal ablation techniques for the treatment of PTMC via a systematic review and meta-analysis. Methods: The Pubmed MEDLINE and EMBASE databases were searched for studies reporting the efficacy and safety of thermal ablations (radiofrequency-, laser-, and microwave-ablations [RFA, LA, and MWA]) until August 10, 2019. A review of 105 potential papers identified 11 eligible papers, including 715 patients. The pooled proportions of complete disappearance and recurrence, and the pooled estimates of mean volume reduction and its rate of the treated PTMC were assessed by using random-effects modeling. The pooled proportions of overall and major complications were calculated. Subgroup analysis was performed according to the treatment modality. Between-study heterogeneity was explored by using χ2 statistic for pooled estimates and inconsistency index I2. Quality of the studies was evaluated by using the Risk of Bias Assessment Tool for Nonrandomized Studies. Results: The pooled proportions of complete disappearance and recurrence of PTMC were 57.6% [95% confidence interval (CI): 35.4-79.8] and 0.4% [95% CI: 0-1.1], respectively. The pooled estimates of mean volume reduction and its rate were 73.5 mm3 [52.4-94.6 mm3] and 98.1% [95% CI: 96.7-99.5], respectively. The pooled proportions of overall and major complications were 3.2% [95% CI: 1.1-5.2] and 0.7% [95% CI: 0-1.5], respectively. Significant between-study heterogeneity was observed for complete disappearance (p < 0.001, I2: 99%), mean volume reduction (p < 0.001, I2: 93%), and its rate (p < 0.001, I2: 86%). Subgroup analysis revealed heterogeneity of the complete disappearance proportion among the treatment modality (I2 range: 95-100%). RFA showed the highest mean volume reduction rate (99.3%), followed by MWA (95.3%) and LA (88.6%) (p < 0.001). Conclusions: All thermal ablation techniques were effective and safe for the treatment of PTMC. However, each treatment modality had significant heterogeneity with respect to complete disappearance of PTMC. Compared with RFA and MWA, LA was less effective in reducing the volume of PTMC.

Abstract
The performance of hyperspectral imaging (HSI) for tumor detection is investigated in ex-vivo specimens from the thyroid (N = 200) and salivary glands (N = 16) from 82 patients. Tissues were imaged with HSI in broadband reflectance and autofluorescence modes. For comparison, the tissues were imaged with two fluorescent dyes. Additionally, HSI was used to synthesize three-band RGB multiplex images to represent the human-eye response and Gaussian RGBs, which are referred to as HSI-synthesized RGB images. Using histological ground truths, deep learning algorithms were developed for tumor detection. For the classification of thyroid tumors, HSI-synthesized RGB images achieved the best performance with an AUC score of 0.90. In salivary glands, HSI had the best performance with 0.92 AUC score. This study demonstrates that HSI could aid surgeons and pathologists in detecting tumors of the thyroid and salivary glands.

Abstract
Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, accounting for 70%–80% of all thyroid malignancies. It is biologically indolent and has an excellent prognosis. Variations in histopathologic patterns are known to influence prognosis and often result in a diagnostic dilemma. We report an unusual case of a 35-year-old female with papillary carcinoma of a thyroid isthmus showing anastomosing channels on histopathology, a distinctive pattern that has not been described in PTC. Similar to tumor cells, the lining cells of these channels were also positive for thyroid transcription factor 1, thyroglobulin, and cytokeratin-19 and negative for CD34 and CD31. The diagnosis of PTC should rely on nuclear morphology rather than architecture. Pathologists should be aware of different variants because some of these variants show aggressive behavior and poor outcome. The present report highlights the distinctive pattern of PTC, recognition of which is important to avoid any diagnostic pitfall.

Abstract
OBJECTIVE The associations between viruses and the cancer have been conducted in several studies while there has been no systematic review and meta-analysis about the association between viral infections and thyroid cancer (TC). Therefore, we investigated the association between viral infection and TC risk. METHODS Systematic search was done from 1994 to 2019 in Web of sciences (ISI), PubMed, and Scopus databases. Pooled logarithm of odds ratio (OR) and their corresponding 95 % confidence interval (CI) and pooled prevalence of viral infections were calculated to find the association between the viral infections and TC risk and overall prevalence of the viral infections in TC. RESULTS Twenty-three of 852 original articles were selected and included in the study. According to the results of the random effect meta-analysis, the pooled prevalence of viral infections in the TC patients was 37 % (95 % C. I = 22 %-55 %). In addition, there was a significant association between viral infections (log (OR) = 1.51, 95 % credible interval = 0.68-2.39) and TC risk. The highest associations were observed between TC risk and Simian Vacuolating Virus 40 (SV40) and B19 infections, respectively. The lowest non-significant association was found between TC risk and Poliovirus type 1 infection. The significantly heterogeneity was observed between included studies (Q test: p-value<0.001; I2 = 73.82 %; τ2 = 1.08, 95 % Cr. I = 0.47-1.94). CONCLUSIONS Results clearly demonstrated the potential pathogenetic association between viral infections and increased risk of TC.

Abstract
Objectives The aim of our study was to evaluate the survival rate of all thyroid carcinomas (TCs) diagnosed in the 1999-2015 period in the Republic of North Macedonia and to analyze the prognostic influence of several characteristics on development of distant metastases, as well as to analyze the prognostic effect of seven clinical and constitutional features on mortality. Material and methods A retrospective analysis of medical data from all TCs diagnosed in 1999-2015 was performed. The survival rate of all types of TCs was estimated using the Kaplan Meier method. Univariate and multivariate logistic regression analysis was applied for evaluation of the predictive role of seven clinical and constitutional characteristics for development of distant metastases, and the univariate Cox-proportional model was applied for evaluation of the predictors for mortality. Results A total of 422 TC cases were diagnosed in the 17-year period, with an average survival time of 212.99 months. Results of the univariate regression analysis showed that dimension at initial ultrasound and histopathological type of tumor were significantly predictive variables for distant metastases. Multifocal tumors vs. unifocal tumors < 15 mm significantly increased the probability of distant metastases by 7.401 (p = 0.005, 95% CI = 1.817-30.190) times. Age, initial lymph node involvement, number of radioiodine therapies, and histopathology of the tumor were selected as independent significant predictors for mortality. Conclusion Our results showed an excellent overall prognosis of thyroid tumors in the Macedonian population. The dimension of the tumor, multifocality, and histopathological type were the most relevant prognostic predictive features for development of distant metastases.

Abstract
BACKGROUND Follicular variant papillary thyroid carcinoma (FVPTC) is a heterogeneous group of tumors that differ morphologically, genetically, and clinically. This study aimed to investigate the gene mutation and gene expression profiles, especially the pathways in the interaction network and the diagnostic approaches of candidate markers of FVPTC. METHODS The clinicopathological characteristics, gene mutation types, and mRNA expression profiles of patients with FVPTC were studied utilizing the data downloaded from The Cancer Genome Atlas (TCGA) database. Differentially expressed genes (DEGs) were identified, and functional enrichment analysis was applied. A protein-protein interaction (PPI) network was constructed to identify hub genes and receiver operating characteristic (ROC) analysis was used to evaluate candidate gene diagnostic values. RESULTS RAS and BRAF mutations were the predominant mutation types in FVPTC. FVPTC was significantly correlated with the absence of extrathyroidal extension, lower N stage, and the low occurrence rate of BRAF mutation compared to classical PTC. Two thousand three hundred and forty-two FVPTC-related differentially expressed mRNAs (DEGs) and 420 FVPTC-specific DEGs were identified in this study. Function enrichment analysis revealed that these DEGs were involved in some pathways in cancer, including the PI3K-Akt signaling pathway and MAPK signaling pathways. The PPI network was constructed from 420 FVPTC-specific DEGs, and a sub-network, including 12 genes and 10 hub genes, was verified. CONCLUSIONS FVPTC was identified significantly relevant to remarkable alterations of gene mutation, DEGs, related pathways and the diagnostic performance of hub genes. Our study might provide further insights into the investigation of the tumorigenesis mechanism of FVPTC and assist in the discovery of new candidate diagnostic markers for FVPTC.

Abstract
The long non-coding (lnc)RNA pre-ribosomal RNA antisense transcripts (PAPAS) can repress ribosomal RNA synthesis, although its role in human disease is currently unknown. The present study aimed to investigate the function of PAPAS in papillary thyroid carcinoma (PTC). PAPAS was downregulated, while the lncRNA HOXA transcript at the distal tip (HOTTIP) was upregulated in patients with PTC. PAPAS and HOTTIP were inversely associated in PTC. PAPAS overexpression led to the downregulation of HOTTIP in PTC cells, while PAPAS expression was not significantly affected by HOTTIP overexpression, suggesting that PAPAS was upstream of HOTTIP. PAPAS expression level decreased, while HOTTIP expression level increased with the increase of clinical staging. PAPAS overexpression led to the inhibition of cell proliferation, while HOTTIP overexpression increased proliferation of PTC cells, and HOTTIP overexpression decreased the effects of PAPAS overexpression. lncRNA PAPAS overexpression may inhibit tumor growth in papillary thyroid carcinoma by downregulating lncRNA HOTTIP.

Abstract
Objective Thyroid cancer has the highest prevalence among the cancer types that affect the endocrine system; however, its molecular mechanisms are not yet determined. Cadherin-16 (CDH16) plays an important role in the tumorigenesis of human cancers, but its influence on papillary thyroid cancer (PTC) is poorly investigated. This study aimed to explore the role of CDH16 in PTC. Methods We performed quantitative real-time polymerase chain reaction to investigate CDH16 expression in PTC. The clinical significance of CDH16 expression in PTC was then evaluated using The Cancer Genome Atlas (TCGA) database. Bioinformatics analysis was also conducted to determine the potential molecular mechanisms of CDH16. Results CDH16 was remarkably downregulated in PTC tumors compared with that in corresponding normal thyroid tissues in the local and TCGA cohorts. This downregulation was associated with unfavorable clinicopathological features, including histological type, high tumor stage, aggressive lymph node metastasis (LNM), and advanced clinical stage. In addition, logistic analyses revealed that the reduced expression of CDH16 can aggravate the risk of LNM in PTC. Bioinformatics analysis indicated that the co-expressed CDH16 genes mainly participated in signaling the cancer-related pathways. Conclusion CDH16 is involved in PTC progression and acts as an LNM-related gene in PTC.

Abstract
According to National Cancer Registry Program, Thiruvananthapuram district of Kerala, has the highest relative frequency of thyroid carcinomas; nevertheless, limited data exist regarding its socio-demographic and clinico-pathological characteristics. The aims of the study were to assess the: (1) demographic characteristics, (2) histopathological features and the relative frequency of various thyroid carcinoma cases and papillary thyroid carcinoma (PTC) subtypes, (3) rising trend of papillary microcarcinomas, and (4) associated lesions. A retrospective study wherein 170 cases of thyroid malignancies reported in our single institution over a period of 8 years period was reviewed. PTC accounted for 97% cases, followed by medullary (n = 4; 2.4%) and follicular carcinoma (n = 1; 0.6%). There was female preponderance (p = 0.0379) with a lower median age in females (p = 0.0275). Among the PTCs, conventional type constituted 53.4% cases (n = 87), followed by microcarcinomas (n = 34; 20.9%), follicular variant (n = 28; 17.2%), and others 14 cases (8.5%). Thirty-three cases (19.4%) showed multifocality, 5 cases (2.9%) extra-thyroid extension, and 19 cases (11.2%) lymph node metastasis. Two cases developed recurrences and three cases, metastasis. The associated lesions were significantly higher in females (p = 0.0059); most common being multinodular goiter (MNG; n = 67; 41.1%), followed by Hashimoto thyroiditis (n = 44; 27%) and lymphocytic thyroiditis (n = 28; 17.2%); MNG being associated with follicular (p = 0.0129), and Hashimoto thyroiditis with conventional variant (p = 0.0475). The frequency of microcarcinomas significantly increased in the past 4 years (p = 0.0291) and was associated with MNG (p = 0.0055), Hurthle cell nodule (p = 0.0315) and absent lymph node metastasis (p = 0.0147). The primary treatment modality was total thyroidectomy. Papillary microcarcinoma cases increased significantly in the past 4 years and were significantly associated with MNG and Hurthle cell nodule. It is challenging to distinguish the various PTC subtypes as recognition of these histological variants warrants better patient management.

Abstract
FOXF1 belongs to the forkhead family of transcription factors. In this study, we aimed to explore the expression profile of FOXF1 in papillary thyroid cancer (PTC) and corresponding adjacent normal tissues, by using data from The Cancer Genome Atlas-Thyroid Cancer (TCGA-THCA) and The Genotype-Tissue Expression (GTEx) project. Also, we studied its prognostic significance in PTC and its potential regulatory network. Results showed that FOXF1 expression was significantly lower in PTC tissues compared with adjacent normal tissues. Subgroup analysis only confirmed the downregulation in classical histological variant, but not in tall-cell and follicular variants. FOXF1 downregulation was associated with advanced T stages, positive nodal invasion, and advanced pathological stages of the classical variants. FOXF1 expression might be a fair prognostic marker in terms of recurrence, which independently predicted favorable RFS (HR:0.114, 95%CI: 0.045-0.289, p < .001). We examined FOXF1 somatic mutations, gene-level copy number alterations (CNAs) and the methylation status of 57 CpG sites in more than 350 classical PTC cases. However, no expression-related genetic and epigenetic alterations were identified. Based on 20,048 genes with RNA-seq data, we identified 16 genes that showed strongly positive co-expression (Pearson's r ≥ 0.6) with FOXF1. Available evidence showed that some of the genes have well-characterized tumor suppressive effects. We hypothesized that some of these genes might be the upstream regulators or downstream effectors of FOXF1 in classical PTC. In conclusion, FOXF1 mRNA was typically downregulated in classical PTC. Its expression might be a specific and independent prognostic biomarker in terms of RFS in classical PTC patients.

Abstract
BACKGROUND To investigate the diagnostic performance of cytology (fine-needle aspiration cytology [FNAC]), thyroglobulin (fine-needle aspiration thyroglobulin [FNA-Tg]), and combination of them in the washout of fine-needle aspiration for those patients who have suspicious metastatic lymph nodes of differentiated thyroid cancer. METHODS Databases, including PubMed, EMbase, Web of Science and Cochrane Library were searched up to June 2019. The quality assessment of diagnostic accuracy scale-2 was used to conduct quality assessments, and publication bias was evaluated using the Deeks funnel plot. STATA version 14.0 was used to perform the meta-analysis. RESULTS A total of 2257 patients with 2786 samples of suspicious metastatic lymph nodes of differentiated thyroid cancer were included in the meta-analysis. The results showed that the diagnostic value for detecting lymph node metastasis of differentiated thyroid cancer was as follows: combination of FNAC and FNA-Tg > FNA-Tg > FNAC. All differences of superiority among them are statistically significant. The sensitivity of the combination was 0.968 (95% confidence interval [CI]: 0.942-0.983), the specificity was 0.932 (95% CI: 0.856-0.969), the diagnostic score was 6.036 (95% CI: 4.892-7.181), the diagnostic odds ratio was 418.424 (95% CI: 133.167-1314.729), and the score of summary receiver operating characteristic was 0.99 (95% CI: 0.97-0.99). CONCLUSIONS The combination of FNAC and FNA-Tg is an excellent procedure in diagnosis of lymph nodes metastasis of patients with differentiated thyroid cancer, which should be highly recommended.

Abstract
INTRODUCTION Distant metastases of papillary thyroid cancers are rare. Most common metastatic sites include bone and lung, whereas metastases to brain, eye, breast, liver, kidney, muscle, and skin are infrequent and almost always appear in advanced-stage tumor disease. Metastases to ovary and/or uterus are even scarcer. We report herein a very exceptional case of asymptomatic malignant-to-benign tumor-to-tumor metastasis of thyroid origin into a uterine leiomyoma. CASE PRESENTATION We present the case of a 53-year-old female patient who had a previous history of pT1b N0 M0 R0 papillary carcinoma of the lower left thyroid lobe, treated by total thyroidectomy and central lymph node dissection and two successive administrations of radioactive treatment with iodine-131. Six years later, follow-up imaging disclosed an asymptomatic slow-growing 40-mm-long pedicled subserous heterogeneous uterine myoma including a 12-mm hypervascular nodule, which was suspicious for thyroid malignancy on MRI. DISCUSSION Histopathology of a hysterectomy specimen disclosed a hypervascular well-limited poorly differentiated trabecular carcinomatous infiltration within the uterine leiomyoma. The immunohistochemical profile of the suspicious nodule was compatible with a thyroid origin. CONCLUSION A hypervascular "hot spot" intramyoma nodule was the diagnostic clue in a clinical context of hematogenous tumor spread of thyroid origin (increased thyroglobulin level).

Abstract
BACKGROUND Theranostics is a combined diagnostic and treatment approach to individualized patient care. Kostmann syndrome, or severe congenital neutropenia, is an autosomal recessive disease that affects the production of neutrophils. Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy associated with gene alterations, including in the mitogen-activated protein kinase (MAPK) signaling pathway gene. Translocation of the ETS variant 6/neurotrophic receptor tyrosine kinase 3 (ETV6/NTRK3) gene has been implicated in radiation-induced and pediatric forms of thyroid carcinoma but has rarely been described in sporadic PTC. This report is of a case of PTC in a patient with Kostmann syndrome associated with ETV6/NTRK3 gene translocation. CASE REPORT A 32-year-old woman with a history of Kostmann syndrome, acute myeloid leukemia (AML), and chronic graft versus host disease (GVHD) was diagnosed with PTC with cervical lymph node metastases and soft tissue invasion following total thyroidectomy and bilateral modified radical neck dissection. Her postoperative radioactive iodine (RAI) scan confirmed lymph node metastasis. Gene expression studies identified increased expression of iodine-handling genes and ETV6/NTRK3 gene fusion. Because of the bone marrow compromise due to Kostmann syndrome and AML, a careful genomic and molecular analysis was performed to guide therapy. CONCLUSIONS This is the first reported case of the association between PTC, Kostmann syndrome, and ETV6/NTRK3 gene translocation in which multimodality treatment planning was optimized by genomic profiling.

Abstract
Recent evidence has revealed that certain microRNAs (miRNAs) are dysregulated in thyroid cancer (TC), which has been associated with the pathogenesis and development of TC. Therefore, improved understanding of the detailed roles of miRNAs that are aberrantly expressed in TC may aid the development of valuable therapeutic methods for the management of patients with this malignancy. In this study, miRNA‑873‑5p (miR‑873) expression in TC tissues and cell lines was detected by reverse‑transcription quantitative polymerase chain reaction (RT‑qPCR). MTT and cell invasion assays were performed to investigate the effects of miR‑873 overexpression on TC cell proliferation and invasion in vitro. Bioinformatics analysis, luciferase reporter assay, RT‑qPCR and western blot analysis were employed to evaluate whether zinc finger E‑box‑binding homeobox 1 (ZEB1) is a direct target of miR‑873 in TC cells. The present study reported that miR‑873 was weakly expressed in human TC tissues and cell lines. Functionally, miR‑873 overexpression suppressed TC cell proliferation and invasion in vitro. Mechanistically, ZEB1 was predicted to be a putative target of miR‑873. In addition, miR‑873 was proposed to directly bind to the 3'‑untranslated region of ZEB1 and decrease its expression in TC cells at the mRNA and protein levels. Furthermore, ZEB1 expression was significantly upregulated in TC tissues and negatively correlated with miR‑873 expression. Furthermore, ZEB1 restoration partially reversed the suppressive effects of miR‑873 overexpression on TC cell proliferation and invasion. These results demonstrated that miR‑873 may serve tumour‑suppressive roles in the progression of TC, and its suppressive effects could be mediated by the inhibition of ZEB1. Therefore, miR‑873 may be a valuable therapeutic target in the management of patients with TC.

Abstract
AIMS Recent evidence indicates an increased incidence of thyroid carcinoma, especially papillary thyroid carcinoma (PTC), in Saudi Arabia. EGFR and CXCR1 were reported to have increased expression in several human neoplasms. The goals of the present research was to investigate EGFR and CXCR1 expression in thyroid carcinoma and correlate the results to the established prognostic factors. METHODS Immunohistochemical study for both EGFR and CXCR1 was performed on formalin-fixed paraffin-embedded thyroid carcinomas tissues sections applying Labeled Streptavidin-biotin method (LSAB). RESULTS Remarkable high expression of EGFR and CXCR1 were observed in PTC cases (56% and 63% respectively). There was association between EGFR expression in PTC and each of histologic subtype, lymph node metastasis (LNM), distant metastasis (DM), TNM staging and tumor relapse. There was statistical significant correlation between CXCR1 expression in PTC and each of histologic subtype, LNM, and tumor relapse. A significant correlation was detected between concomitant EGFR and CXCR expression and LNM, DM, increasing stage and tumor relapse. CONCLUSIONS The results of the present study demonstrated, a statistically positive correlation of EGFR and CXCR1 expression in PTC compared to normal thyroid tissues and nodular hyperplasia in Qassim Region- Saudi Arabia. Concomitant high expression of both receptors were strongly correlated with LNM, DM, TNM stage and tumor relapse than did each alone. These findings suggest that EGFR and CXCR1 play crucial roles in PTC and serve as predictors of poor prognosis, biomarkers of tumor diagnosis, and potential targets of cancer therapeutics.

Abstract
Thyroid carcinoma (TC) comprises a spectrum of different tumors with a wide range of biological behavior and prognosis. The techniques based on the latest trends in molecular biology may have application in diagnosis of metastatic TC. The aim of this study was to apply and analyze mRNA expression in peripheral blood of thyrotropin receptor [thyroid stimulating hormone receptor (TSHR-mRNA)] gene and thyroglobulin (Tg-mRNA) gene using 2–ΔΔCt method in differentiated TC patients and healthy individuals. Fifty-seven subjects were included in the study, consisting of 40 patients with TC and 17 healthy volunteers as a control group. Total RNA was isolated from peripheral blood and used for two-step reverse transcriptase-polymerase chain reaction (PCR). Real-time PCR was performed with appropriate primers. Relative quantification using the 2–ΔΔCt method was applied. Thyroid carcinoma patients with metastatic disease or loco-regional relapse expressed TSHR-mRNA by a 8.57-fold higher level than healthy controls. Thyroid carcinoma patients with biochemical relapse expressed TSHR-mRNA by a 14.17-fold higher level than healthy controls, while expression of Tg-mRNA was 6.6-fold higher in TC patients with metastatic disease and loco-regional relapse than healthy controls and 8.34-fold higher level compared with TC patients with excellent response to treatment. Our preliminary study showed that the TSHR gene expression might have more useful application as a biomarker compared to detection of Tg gene expression.

Abstract
Objective Gene alterations leading to activation of the MAPK pathway are of interest for targeted therapy in patients with advanced radioactive iodine refractory (RAI-R) thyroid carcinoma. Due to technical reasons gene fusion analysis in RNA isolated from formalin-fixed tumor tissues has till now been limited. The objective of the present study was to identify targetable gene rearrangements in RNA isolated from formalin-fixed RAI-R thyroid carcinomas. Design Retrospective study in 132 patients with RAI-R thyroid carcinoma (59 papillary-, 24 follicular-, 35 Hürthle cell- and 14 anaplastic thyroid carcinoma). Methods Total nucleic acid (undivided DNA and RNA) was isolated from formalin-fixed tissue. Extensive gene fusion analysis was performed in all samples that tested negative for pathogenic BRAF, NRAS, HRAS and KRAS variants. Results Seven targetable gene fusions were identified in the remaining 60 samples without known DNA variants. This includes frequently reported gene fusions such as CCDC6/RET (PTC1), PRKAR1A/RET (PTC2) and ETV6/NTRK3 , and gene fusions that are less common in thyroid cancer (TPM3/NTRK1, EML4/ALK and EML4/NTRK3). Of note, most gene fusions were detected in papillary thyroid carcinoma and MAPK-associated alterations in Hürthle cell carcinomas are rare (2/35). Conclusion Targetable gene fusions were found in 12% of RAI-R thyroid carcinoma without DNA variants and can be effectively identified in formalin-fixed tissue. These gene fusions might provide a preclinical rationale to include specific kinase inhibitors in the treatment regimen for these patients. The latter intends to restore iodine transport and/or take advantage of the direct effect on tumor cell vitality once progressive disease is seen.

Abstract
Background The macrofollicular variant of papillary thyroid cancer (MFVPTC) is a rare histological variant of papillary thyroid cancer (PTC), with only 71 cases reported through 2014. This study analyzed the clinical, preoperative thyroid ultrasonography (US), and fine needle aspiration cytology (FNAC) features; and therapeutic outcomes of 11 patients with MFVPTC. Methods The records of 393 patients with histologically diagnosed follicular variant of papillary thyroid carcinoma (FVPTC), including 11 with MFVPTC, were retrospectively reviewed. Preoperative thyroid US findings, clinical presentation, treatment outcomes, and survival rates were analyzed. Result Mean tumor size was significantly greater in patients with MFVPTC than that in those with FVPTC (4.2 ± 2.1 cm vs. 2.9 ± 1.7 cm; p = 0.016). No patient with MFVPTC had lymph node involvement, but one had a micrometastasis to the lung, which responded well to therapeutic radioiodine. All MFVPTC lesions were isoechoic on US. Eight nodules had calcifications and eight had irregular margins. FNAC showed that these tumors had low cellularity, absence or focal presence of enlarged clear nuclei, and subtle or focal nuclear features of PTC. Cells were, arranged in microfollicular pattern, with abundant colloid background. Multifocal PTCs were detected in the opposite lobe of two patients. All 11 patients with MFVPTC had excellent outcomes. No patient experienced recurrence, and survival rates were high. Conclusions Malignant US criteria combined with FNAC features have a low preoperative diagnostic rate for MFVPTC. Surgery is recommended for patients with thyroid nodules larger than 4 cm and those with subtle and focal atypical nuclei in FNAC.

Abstract
Escalating evidence suggests that microRNA-101 (miR-101) is implicated in the development and progression of various cancers, including papillary thyroid carcinoma (PTC). However, the biological function and molecular mechanisms of miR-101 in PTC are still unclear. In this study, we demonstrated that miR-101 expression was significantly decreased in PTC tissues and cell lines. Clinically, a low level of miR-101 was positively associated with advanced histological stages and lymph node and distant metastases. The expression of CXCL12 was negatively correlated with miR-101 level in PTC. CXCL12 was validated as a direct target of miR-101 in PTC cells. Functional experiments proved that miR-101 markedly reduced the proliferation, apoptosis escape, migration, and invasion of PTC cells. Moreover, CXCL12 restoration rescued the suppressive effects of miR-101 on PTC cells by activating Akt- and EMT-associated signaling pathways. Overall, miR-101 exerts oncostatic effects on PTC by downregulating CXCL12 and repressing its downstream Akt and Snail signaling pathways, suggesting that miR-101/CXCL12/Akt or Snail axis may serve as a potential therapeutic target for PTC.

Abstract
Papillary thyroid cancer (PTC) is the most prevalent form of malignancy among all cancers of the thyroid. It is also one of the few cancers with a rapidly increasing incidence. PTC is usually contained within the thyroid gland and generally biologically indolent. Prognosis of the cancer is excellent, with less than 2% mortality at 5 years. However, more than 25% of patients with PTC developed a recurrence during a long term follow-up. The present article provides an updated condensed overview of PTC, which focuses mainly on the molecular alterations involved and recent biomarker investigations.

Abstract
MicroR-141-3p has been found to be downregulated in papillary thyroid carcinoma (PTC), while little is known about the cellular functions and precise signals elicited by miR-141-3p in PTC. The results of this study indicated that the expression of miR-141-3p was aberrantly down-regulated in PTC tissues and cell lines, compared with the adjacent normal tissues and normal thyroid epithelial cells. Furthermore, the miR-141-3p expression level was negatively associated with TNM stage and lymph node metastasis in PTC. Expression of miR-141-3p effectively inhibited cell growth, promoted apoptosis, and suppressed invasion in PTC cells. Meanwhile, miR-141-3p knockdown with miR-141-3p inhibitor reversed these effects. Consistent with the in vitro study, miR-141-3p also exhibited anti-neoplastic activity in vivo. Moreover, the results revealed that miR-141-3p directly recognized the 3' untranslated region (3'UTR) of Yin Yang 1 (YY1) and negatively regulated the expression of YY1 at both protein and mRNA levels. Ectopic expression of YY1 could effectively abrogate the anti-metastatic and proapoptotic effects of miR-141-3p. In summary, the findings suggested that miR-141-3p can act as a tumor suppressor in PTC and may be a potential therapeutic target for PTC treatment.

Abstract
INTRODUCTION Hürthle cell adenoma is a rare benign lesion of the thyroid gland, however, controversies about its potential malignant behavior still remain. Among thyroid neoplasms, papillary carcinoma is the most common variant with great variety of histological subtypes demonstrating different biological behavior. AIM To raise the awareness of possible coexistence of these two lesions and discussion about possible therapeutic approaches. CASE REPORT A 42 year old female patient was examined because of the pain in the thyroid area. Cytological examination suggested Hürthle cell adenoma. Subsequently, right thyroid lobectomy was performed. Intraoperative frozen sections confirmed the diagnosis, yet final histological analysis revealed encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC), now reclassified as noninvasive follicular thyroid neoplasm with papillary- like nuclear features (NIFTP) within the adenoma, which was not noticed through scintigraphy, ultrasound, cytological and frozen section analysis. CONCLUSIONS Problems concerning both diagnostic and therapeutic approach to these lesions are being discussed, since opinions reported in the literature are divided, posing great challenge for the clinician in determining adequate therapeutic procedures.

Abstract
BACKGROUND Thyroid cancer is a common endocrine malignancy whose incidence has increased in recent years. Several internal and external risk factors are involved in the development of this cancer, such as infectious agents. Evidence supporting the role of viral infection as an etiology for the invasiveness of thyroid cancer is increasing. The aim of this study was to determine the presence of the Epstein-Barr virus (EBV) and the association between viral gene products and thyroid tumor development. METHODS Fifty-seven thyroid cancer specimens were collected from the same number of patients as well as 18 samples from healthy controls. The presence of the EBV genome and the genotyping was examined by polymerase chain reaction (PCR). Also, an enzyme-linked immunosorbent assay and real-time PCR were used to measure the expression levels of viral and cellular genes. RESULTS The EBV DNA was detected in 71.9% of the samples, and it was also found that the presence of the EBV was associated with increasing development of thyroid tumor. CONCLUSION Our results demonstrated that EBV infection may play a role in the development of thyroid tumor.

Abstract
PROBLEM STATEMENT The aim of our study was to identify predictive factors for lymph node metastases (LNM) in children and adolescents with papillary thyroid carcinoma (PTC) and their impact on survival. METHODS The authors conducted an Italian multicentric retrospective analysis on 132 pediatric patients (0-18 years old) affected by PTC between 2000 and 2014. The investigated variables were demographic characteristics of the patients, clinicopathological features of PTCs, and persistence/recurrence of disease. The female/male ratio was 3.1:1. The median age was 14.3 ± 3.5 years (range 4-18 years). Total thyroidectomy was performed in all the patients, followed by lymph node dissection in 87 patients (65.9%). Metastatic lymph node involvement was confirmed in 73 patients (55.3%): lateral compartment (LC) in 25 patients (34.2%), central compartment (CC) in 17 patients (23.3%), and both compartments in 31 patients (42.5%). RESULTS Multifocality (P < .00), vascular invasion (P = .04), infiltration of the thyroid capsule (P < .00), minimal extrathyroidal extension (P < .00), diffuse sclerosing variant of PTC (P = .02), and presence of LNM in the LC (P < .00) were significantly associated with LNM in CC. Infiltration of the thyroid capsule (P < .00), massive extrathyroidal extension (P = .03), distant metastases (P = .02), PTC, not otherwise specified (P < .00), and presence of LNM in the CC (P < .00) were significantly associated with LNM in LC. Age, sex and size of PTC were not correlated with the presence of cervical LNM. Moreover, presence of LNM in CC increases the risk of persistence (P < .01) and recurrence (P < .02) of PTC in children and adolescents. CONCLUSIONS Most predictors, unfortunately, are only identified post-operatively by histopathologic examination: Just a small part of them can be pre-operatively detected with a low-sensitivity neck ultrasonography. In PTC patients with pre-operative predictors, we suggest an accurate pre- and intra-operative evaluation of CC and/or LC to find suspicious lymph nodes. The presence of LNM in CC has an impact on disease/progression/relapse-free survival. We suggest performing RAI therapy and an accurate follow-up for pediatric patients with only post-operative predictors.

Abstract
Type 2 taste receptors (T2Rs, TAS2Rs) mediate bitterness perception and are involved in diverse defence mechanisms in extraoral tissues. The thyrocyte-expressed T2Rs control thyroid hormone production, and this regulatory role may be associated with susceptibility to thyroid diseases. This study examined whether the variations in TAS2Rs modify the risk of papillary thyroid carcinoma (PTC) and whether such T2R-related PTC risk is associated with genetically modified thyroid function. We conducted a case-control study with 763 Korean females, including 250 PTC cases. Seventy-three single-nucleotide polymorphisms in 13 TAS2R genes and the pre-diagnosis levels of 4 thyroid-related functional markers [total triiodothyronine (TT3), free thyroxine, thyroid-stimulating hormone and thyroglobulin] were analysed. Individuals with TAS2R3/4 CC haplotype (rs2270009 and rs2234001) were at a lower risk for PTC than those with the remaining haplotypes (odds ratio = 0.59, 95% confidence interval: 0.36-0.97). Furthermore, TT3 levels were significantly reduced for TAS2R3/4 CC haplotype carriers compared with other haplotype carriers (p = 0.005). No other genetic variants exhibited critical associations with the PTC phenotype and biomarkers. In summary, genetic variations in T2R3/4 bitterness receptors may modify the PTC risk, and the genetically modified thyroid hormone level by those variations may be linked with the PTC-T2Rs association.

Abstract
Papillary thyroid carcinoma (PTC) is diagnosed in both cytological and histological specimens on the basis of distinct nuclear morphology. These features may not be prominent in some PTC variants and may be seen in some benign conditions. It is necessary to differentiate PTC from other neoplastic and nonneoplastic lesions since it affects treatment strategy and patients' fate. Emerin is a type II integral membrane protein of the inner nuclear membrane that has a characteristic staining pattern in PTC. CD56 is a homophilic membrane glycoprotein that is expressed in thyroid follicular epithelial cells and adrenal glands. The aim of this study was to evaluate the diagnostic value of emerin (positivity, percentage, and highlighting nuclear features) and CD56 (positive versus negative) both singly and in combination for differentiation of PTC from other neoplastic and nonneoplastic mimics. This study was performed on 50 cases of PTC, 9 cases of follicular adenoma (FA), and 12 cases of nonneoplastic thyroid lesions using immunohistochemistry for detection of emerin and CD56. Positive emerin expression was seen in 82% of PTC and in 16.7% of nonneoplastic cases with an absence of expression in FA. CD56 was expressed in 88.9% of FA, 91.7% of nonneoplastic cases and in a minority of PTC cases (6%). Positive emerin revealed 82% sensitivity and 90% specificity, while emerin-highlighted nuclear changes was more specific (95%). Negative CD56 expression revealed 84% sensitivity and 90% specificity. Combined positive emerin (including highlighting nuclear changes) and negative CD56 showed 72% sensitivity and 100% specificity. Positive emerin expression (moderate/strong) and its highlighting nuclear changes combined with negative CD56 could be a very helpful procedure in difficult and overlapping cases with high diagnostic validity (high specificity and positive predictive value).

Abstract
Synthesis and storage of thyroglobulin as well as synthesis of thyroid hormones and their release into the circulation are important functions of thyroid, which were studied in fine needle aspiration (FNA) smears from thyroid lesions. Evidence of thyroglobulin synthesis was demonstrated in neoplastic and nonneoplastic follicular cells, especially in Hürthle cells, in the form of colloid inclusions. Whereas the pinocytic vesicles containing colloid at the luminal end of in nonneoplastic and neoplastic follicular cells indicated engulfment of colloid for synthesis of thyroid hormones (T3 and T4), the marginal vacuoles (MVs) (fire-flare appearance) at the basal aspects of follicular cells suggested their release on way to the interfollicular capillaries. The morphological evidence of secretary activity could also be demonstrated in medullary thyroid carcinoma (MTC) in the form of azurophilic granules, marginal vacuoles, and intracytoplasmic lumina (ICL) with secretions; the secretory material, likely to be amyloid, present in MTC cells, and their release to the extracellular space was confirmed by positive immunocytochemical staining for calcitonin. It was found that nuclear grooves and related intranuclear cytoplasmic inclusions (INCIs) in papillary thyroid carcinoma (PTC) possibly represent an initial step of a degenerative process leading to formation of inactive cerebriform nuclei. Based on observation regarding formation and release of precursor substances for psammoma bodies (PBs), it was also suggested that PBs may not represent a process of dystrophic calcification over infarcted/dead papillae but suggest an active biological process, which leads to inhibition of growth of neoplastic cells and acts as a barrier against spread of PTC.

Abstract
Thyroid malignancies are one of the fastest growing cancers in the world, with the majority being papillary thyroid cancer. Follicular variant of papillary thyroid cancer accounts for about 10%-20% of papillary thyroid carcinomas. The usual sites for metastases of these tumours are lungs and bones with renal metastases being extremely rare. We describe a case of a 64-year-old woman who presented with abdominal pain. On subsequent imaging, she was found to have a colonic mass with metastatic lesions in the lungs and tumour involving left kidney. On biopsy and immunohistochemical staining, the renal mass showed positivity for thyroid cancer markers. Thyroid scan was noted to be negative and the patient was placed on active surveillance after undergoing chemotherapy for colonic adenocarcinoma.

Abstract
This article reviews the small percentage of thyroid tumours that are not classified as classic papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma. It includes subtypes of papillary thyroid carcinoma, including, tall-cell, hobnail/micropapillary, columnar cell, diffuse sclerosing and solid variants. Poorly differentiated carcinoma, high-grade carcinoma and anaplastic thyroid carcinoma are reviewed. Also discussed are entities that are unusual but need to be recognized as primary thyroid neoplasms, i.e. mucoepidermoid carcinoma, sclerosing mucoepidermoid carcinoma with eosinophilia, and mammary analogue secretory carcinoma/secretory carcinoma. The pathological features and prognostic factors are described; a brief review of molecular correlates of these neoplasms is included.

Abstract
MicroRNAs (miRs) function as tumor suppressors or oncogenes in tumor development and progression. The present study reported that miR-409-3p was significantly downregulated in human papillary thyroid carcinoma (PTC) tissues and cell lines. Overexpression of miR-409-3p suppressed cell proliferation and induced cell cycle G0/G1 phase arrest in PTC cells. Further study revealed that the transcriptional regulator cyclin D2 was a target of miR-409-3p, as miR-409-3p bound directly to its 3'-untranslated region and the miR-409-3p mimic reduced the protein expression levels of cyclin D2. In addition, restoration of cyclin D2 expression reversed the inhibitive effect of miR-409-3p on PTC cells. To the best of our knowledge, these findings demonstrate for the first time that miR-409-3p functions as a tumor suppressor in PTC and could serve as an efficient agent for therapy of PTC.

Abstract
Papillary thyroid carcinomas account for ∼80% of well-differentiated thyroid tumors. During the past decade, several new variants of papillary-like thyroid neoplasms and papillary thyroid carcinomas have been recognized. Some of these neoplasms that were previously classified as malignant have been reclassified as low-grade neoplasms, as the diagnostic criteria have evolved. Similarly, some of the papillary thyroid carcinomas that were previously classified as conventional or classic papillary thyroid carcinomas have now been recognized as more aggressive variants of papillary thyroid carcinomas. Recognizing these differences becomes more important for the proper medical, surgical, and radiotherapeutic management of patients with these neoplasms.

Abstract
The papillary thyroid carcinoma (PTC) is the most common malignant tumor of the thyroid gland, with disruptive mutations in mitochondrial complex I subunits reported at very low frequency. Furthermore, metabolic diversity of PTC has been postulated owing to variable messenger RNA (mRNA) expression of genes encoding subunits of the oxidative phosphorylation (OXHPOS) complexes. The aim of the present study was to evaluate the metabolic diversity of the OXPHOS system at the protein level by using immunohistochemical staining. Analysis of 18 human PTCs revealed elevated mitochondrial biogenesis but significantly lower levels of OXPHOS complex I in the tumor tissue (p < 0.0001) compared to the adjacent normal tissue. In contrast, OXPHOS complexes II–V were increased in the majority of PTCs. In three PTCs, we found pathologic mutations within mitochondrially encoded complex I subunits. Our data indicate that PTCs are characterized by an oncocytic metabolic signature that is in low complex I is combined with elevated mitochondrial mass and high complex II–V levels, which might be an important factor for tumor formation.

Abstract
BACKGROUND Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor previously known as noninvasive subtype of encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC). The absence of BRAFV600E mutations has been considered characteristic of NIFTPs. However, a recent study from Korea found that 28.6% of NIFTPs harbored a BRAF mutation. This study evaluated BRAF and RAS mutations in NIFTPs and invasive subtype of EFVPTCs. METHODS This study enrolled 32 patients with NIFTP and 48 with invasive EFVPTC. BRAF, NRAS, HRAS, and KRAS mutations were evaluated by direct sequencing using DNA from fresh-frozen tissues and formalin-fixed, paraffin-embedded tissue samples. RESULTS The primary tumor size of NIFTP was smaller than that of invasive EFVPTC (median 2.8 cm vs. 3.2 cm; p = 0.03). Cervical lymph node metastases were found in only four (8%) patients with invasive EFVPTC. There was no BRAF mutation in NIFTPs, whereas invasive EFVPTCs had three (6%) BRAFV600E mutations and one (2%) BRAFK601E mutation. RAS mutations were detected in 15 (47%) NIFTPs and 22 (46%) invasive EFVPTCs. NRAS mutations in codon 61 were the most common mutations in NIFTPs (34%) and invasive EFVPTCs (27%). There was no significant difference in the frequency of RAS mutations between the two groups. CONCLUSIONS There was no BRAF mutation in any of the NIFTPs. RAS mutations, particularly mutations in codon 61 of NRAS, were the most common mutations in both NIFTPs and invasive EFVPTCs. The presence of a RAS mutation is not helpful for preoperative differentiation between NIFTPs and invasive EFVPTCs.

Abstract
PURPOSE Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. AIM The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. MATERIAL AND RESULTS A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. CONCLUSION This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to have more aggressive biological course and need early detection and other kind of treatment.

Abstract
Papillary thyroid cancer (PTC) accounts for 80–90% of all thyroid malignancies. The tall cell variant (TCV) is a rare aggressive histotype of PTC. We performed a meta-analysis to compare the clinicopathological characteristics and prognostic factors of TCV with those of classical papillary thyroid carcinoma (cPTC). A literature search was performed using the PubMed and EMBASE databases using Medical Subject Headings and keywords. Twenty studies that included 1871 patients with TCV and 75323 patients with cPTC were included in our meta-analysis. Odds ratios and confidence intervals were calculated for each study. Patients with TCV were associated with multifocality, higher TNM stage, extrathyroidal extension, vascular invasion, lymph node metastasis, distant metastasis, BRAF mutation, disease-specific survival, and overall survival. We found that TCV cases were associated with more aggressive clinicopathological characteristics and poorer prognoses than cPTC cases were. Our results suggest that TCV is a high-risk PTC that warrants aggressive treatment and follow-up strategies.

Abstract
BACKGROUND Histologic subtypes of papillary thyroid cancer affect prognosis. The objective of this study was to examine whether survival is affected by extent of surgery for conventional versus follicular-variant papillary thyroid cancer when stratified by tumor size. METHODS Using the National Cancer Data Base, we evaluated 33,816 adults undergoing surgery for papillary thyroid cancer from 2004 to 2008 for 1.0-3.9 cm tumors and clinically negative lymph nodes. Conventional and follicular-variant papillary thyroid cancers were divided into separate groups. Cox regression models stratified by tumor size were used to determine if extent of surgery affected overall survival. RESULTS A total of 30,981 patients had total thyroidectomy and 2,835 had thyroid lobectomy; 22,899 patients had conventional papillary thyroid cancer and 10,918 had follicular-variant papillary thyroid cancer. On unadjusted KM analysis, total thyroidectomy was associated with improved survival for conventional (P = 0.02) but not for follicular-variant papillary thyroid cancer patients (P = 0.42). For conventional papillary thyroid cancer, adjusted analysis showed total thyroidectomy was associated with improved survival for 2.0-3.9 cm tumors (P = 0.03) but not for 1.0-1.9 cm tumors (P = 0.16). For follicular-variant, lobectomy and total thyroidectomy had equivalent survival for 1.0-1.9 cm (P = 0.45) and 2.0-3.9 cm (P = 0.88) tumors. CONCLUSION Tumor size, histologic subtype, and surgical therapy are important factors in papillary thyroid cancer survival. Total thyroidectomy was associated with improved survival in patients with 2.0-3.9 cm conventional papillary thyroid cancer, and should be considered for 2.0-3.9 cm papillary thyroid cancers when preoperative molecular analysis is not used to distinguish conventional from follicular-variant.

Dou R, Zhang L, Lu T, Liu D, Mei F, Huang J, Qian L. Identification of a novel HRAS variant and its association with papillary thyroid carcinoma. Oncol Lett 2018; 15:4511-4516. [PMID: 29556290 DOI: 10.3892/ol.2018.7818] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Accepted: 12/11/2017] [Indexed: 12/27/2022] Open
Abstract
HRas proto-oncogene (HRAS) is one of the most commonly mutated genes in thyroid cancer, with mutations frequently occurring in the follicular and Hurthle cell subtypes. However, the contribution of mutations in HRAS to papillary thyroid carcinoma (PTC) progression and the tall-cell variant (TCV) is poorly understood. The aim of the present study was to investigate the somatic genetic variants present in HRAS in patients with PTC, and to investigate the association of these mutations with PTC. The present study is a retrospective case-control study using tumor samples collected from 139 patients with PTC and blood samples from 195 healthy individuals. All patient samples were screened for mutations in 'hotspot' regions of HRAS and B-raf proto-oncogene (BRAF) by single-stranded conformational polymorphism analysis, followed by direct sequencing. A novel variant (IVS1-82del gctgggcctggg) in the HRAS 5'-untranslated region was identified. There was no difference in age or sex of patients with PTC and the healthy controls; however, the HRAS variant was more frequently detected in PTC tissue than in the healthy control samples (37 vs. 26%, P=0.04). There was no association between the HRAS variant and age, sex, tumor size, encapsulation, multifocality/intra-thyroidal spread, Tumor-Node-Metastasis stage, history of Hashimoto's disease, BRAF V600E mutation or PTC subtype (all P>0.05). There were differences of BRAF V600E distribution among different subtypes (χ2=6.390, P=0.041). HRAS variant co-occurring with the BRAF V600E mutation accounted for 31.6% of the total number (P=0.196). Therefore, this novel variant of HRAS (IVS1-82del gctgggcctggg) may be associated with PTC; however, larger scale studies are required to assess the contribution of this novel HRAS variant to PTC progression.

Abstract
MicroRNAs (miRNAs) have emerged as important gene regulators and are recognized as key players in carcinogenesis. In this study, we investigated the biological function and mechanism of miR-613 in the regulation of papillary thyroid cancer (PTC) development. We found that miR-613 was downregulated in PTC cell lines and tissues, and overexpression of miR-613 significantly suppressed PTC cell growth, migration and invasion in vitro and inhibited tumor growth in vivo. We identified the gene for sphingosine kinase 2 (SphK2) as a direct target of miR-613. Overexpression of miR-613 significantly repressed SphK2 expression by directly targeting its 3'-untranslated regions (3'-UTR) and restoration of SphK2 reversed the inhibitory effects of miR-613 on PTC cell growth and invasion. Taken together, our results indicated that miR-613 functions as a tumor suppressor in PTC and its suppressive effect is mediated by repressing SphK2 expression.

Abstract
As in many cancer types, miRNA expression profiles and functions have become an important field of research on non-medullary thyroid carcinomas, the most common endocrine cancers. This could lead to the establishment of new diagnostic tests and new cancer therapies. However, different studies showed important variations in their research strategies and results. In addition, the action of miRNAs is poorly considered as a whole because of the use of underlying dogmatic truncated concepts. These lead to discrepancies and limits rarely considered. Recently, this field has been enlarged by new miRNA functional and expression studies. Moreover, studies using next generation sequencing give a new view of general miRNA differential expression profiles of papillary thyroid carcinoma. We analyzed in detail this literature from both physiological and differential expression points of view. Based on explicit examples, we reviewed the progresses but also the discrepancies and limits trying to provide a critical approach of where this literature may lead. We also provide recommendations for future studies. The conclusions of this systematic analysis could be extended to other cancer types.
