A recent involvement of sub-population of stem cells, cancer stem cells, has been proposed in different histological types of thyroid cancer. Because of their ability of self-renewal and differentiation into various specialized cells in the body, these putative cells drive tumor genesis, metastatic activity and are responsible to provide chemo- and radioresistant nature to the cancer cells in the thyroid gland. Our Review was conducted from previously published literature to provide latest apprises to investigate the role of embryonic, somatic and cancer stem cells, and discusses the hypothesis of epithelial-mesenchymal transition. Different methods for their identification and isolation through stemness markers using various in vivo and in vitro methods such as flow cytometry, thyrosphere formation assay, aldehyde dehydrogenase activity and ATP-binding cassette sub-family G member 2 efflux-pump mediated Hoechst 33342 dye exclusion have been discussed. The review also outlines various setbacks that still remain to target these tumor initiating cells. Future perspectives of therapeutic strategies and their potential to treat advanced stages of thyroid cancer are also disclosed in this review.展开更多

Methods： 326 negative neck lymph nodes of 68 cases with follicular thyroid carcinoma on routine pathology were examined by keratin-19 monoclonal antibody and S-P JmmunohJsto- chemistry to confirm lymph node micrometastasis. Follow-up pathological and clinical documents were compared. Results： Forty-six neck lymph nodes showed positive micrometastasis among 326 negative neck lymph nodes including 4 lymph nodes in Level Ⅱ （4/42）, 5 lymph nodes in Level Ⅲ （5/34）, 5 lymph nodes in Level Ⅳ （5/49）, 1 lymph node in Leve Ⅳ （1/17） and 31 lymph nodes in Level Ⅳ （31/184）. Six in 14 cases with positive micrometastasis showed distant metastasis or local recurrence, but only 3 in 54 cases with negative micrometastasis indicated distant metastasis or local recurrence （P 〈 0.01）. Conclusion： The research showed that Level VI neck lymph node micrometastasis is possibly occur and closely related with local recurrence and metastasis in follicular carcinoma of thyroid.展开更多

Methods: Eighty patients with thyroid lesions were examined for expression of ras and p53 genes by the labeled streptavidin biotin peroxidase (LSAB) method. Of these patients, 54 were diagnosed (average age: 39.9±15.9 years) with malignant lesions. Of those included in the study, 31 has papillary carcinoma, 13 had follicular carcinoma, 7 had medullary carcinoma, 3 had undifferentiated carcinoma and 19 were stratified to stage I, 28 to stage II, 2 to stage III and 5 to stage IV according to TNM staging system. Twenty-six benign nodular thyroid disorders were studied as control. Results: Positive immunostain results for ras and p53 genes were statistically significant between thyroid carcinomas and benign disorders (90.7% vs 23%, 55.5% vs 30.7%,P<0.05). Both p53 and ras overexpressions coexisted in 30 thyroid carcinomas, and of these, 3 died and 5 had recurrences within 4 years. Conclusions: Activation of ras gene and inactivation of p53 gene were cooperatively associated in thyroid tumorigenesis. The concurrent overexpressions of ras and p53 could result in a poor prognosis.展开更多

Methods： By using ELISA method, we detected the serum levels of MBL and MASP-2 in 26 patients with papillary thyroid carcinoma （PTC）, 30 patients with thyroid adenoma （TA） and 26 healthy people, respectively. Results： Serum MBL level was （565.23 ± 76.70） μg/L in PTCs higher than （324.267 ±24.74） μg/L in TAs, and （152.69± 16.95） IJg/L in healthy of controlling group. There was statistical significance between PTC and TA （P 〈 0.05）, however there was no difference between TA and healthy （P 〉 0.05）. Serum MASP-2 level was （726.153± 78.88） pg/L in PTCs higher than （379.266 ± 30.26） μg/L in TAs, and （203.846 ± 29.09） μg/L in healthy. Serum MASP-2 level was higher in PTCs than TAs, and the difference had statistical significance （P 〈 0.01）. But no difference was observed between in TAs and healthy. Conclusion： These findings might reflect inflammatory processes induced by defense mechanisms, in response to the development of the turnout. MBL may also be involved in the elimination of possible tumourigenic pathogens.展开更多

The role of NRARP in carcinogenesis deserves extensive investigations. This study attempted to investigate the expression of NRARP in thyroid cancer tissues and assess the influence of NRARP on cell proliferation, apoptosis, cell cycle, and invasion in thyroid cancer. Methods： Thirty-four cases with thyroid cancer were collected from the Department of General Surgery, Xinhua Hospital, Shanghai ]iao Tong University School of Medicine between 2011 and 2012. lmmunohistochemistry was used to detect the level of N RARP in cancer tissues. Lentivirus carrying NRARP-shRNA （Lenti-NRARP-shRNA） was applied to down-regulate NRARP expression. Cell viability was tested after treatment with Lenti-NRARP-shRNA using 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide assay. Apoptosis and cell cycle distribution were determined by flow cytometry. Cell invasion was tested using Transwell invasion assay. In addition, expressions of several cell cycle-associated and apoptosis-associated proteins were examined using Western blotting after transfection. Student＇s t-test, one-way analysis of variance （ANOVA）, or Kaplan Meier were used to analyze the differences between two group or three groups. Results： N RARP was highly expressed in thyroid cancer tissues. Lenti-NRARP-shRNA showed significantly inhibitory activities against cell growth at a multiplicity of infection of l 0 or higher （P 〈 0.05）. Lenti-NRARP-shRNA-induced G 1 arrest （BHTl 01 ： 72.57% ± 5.32%; g305C： 75.45% ± 5.26%） by promoting p21 expression, induced apoptosis by promoting bax expression and suppressing bcl-2 expression, and inhibited cell invasion by suppressing matrix metalloproteinase-9 expression. Conclusion： Downregulation of NRARP expression exerts significant antitumor activities against cell growth and invasion of thyroid cancer, that suggests a potential role of NRARP in thyroid cancer targeted therapy.展开更多

The aim of this study was to investigate the possibility of a scarless neck surgery under endoscopy for the treatment of thyroid tumor and to observe the results of this procedure.Methods A total of 68 patients （64 women and 4 men） underwent the surgery. Their ages ranged from 18 to 65 years,with a mean age of （34±3） years. There were 64 cases of thyroid adenoma, and 4 cases of nodular goiter. An incision was made on the surface of the chest bone. The operation cavity was made by dragging the skin. Sixty-four patients underwent partial thyroid lobectomy, four patients underwent thyroid lobectomy.Results All 68 cases showed healing in one stage. None of the cases showed paralysis of the recurrent laryngeal nerve or tumor recurrence within the next 2 to 60 months of follow-up. The patients experienced slight pain after the operation.The patients were satisfied with the cosmetic results of the surgery.Conclusion The gasless endoscopic surgery through the upper chest, which was performed to treat thyroid tumor, did not leave any scar, and was easy to handle, and gave good cosmetic results.展开更多
