Abstract Background Benign thyroid nodules (BTN) are frequently diagnosed as papillary thyroid carcinoma (PTC), leading to unnecessary treatment. We found that plasma lncRNA DLG1-AS1 was upregulated in PTC patients but not in BTN patients and healthy controls. Methods In this study DLG1-AS1 and miR-199a-3p in plasma of both PTC patients and BTN patients were detected by qPCR. ROC curve analysis was performed for diagnostic analysis. Overexpression experiments were performed to analyze the interaction between DLG1-AS1 and miR-199a-3p. CCK-8 assay was performed to analyze cell proliferation. Results In this study, upregulation of DLG1-AS1 distinguished PTC patients from BTN patients and healthy controls. Plasma miR-199a-3p was downregulated in PTC patients compared with healthy controls and BTN patients. Plasma levels of miR-199a-3p were inversely correlated in PTC patients, but not in BTN patients and healthy controls. miR-199a-3p overexpression failed to significantly affect DLG1-AS1, while DLG1-AS1 overexpression resulted in downregulated miR-199a-3p, In addition, DLG1-AS1 overexpression promoted the proliferation of PTC cells. miR-199a-3p overexpression played an opposite role and attenuated the effects of DLG1-AS1 overexpression. Conclusions Therefore, DLG1-AS1 may promote PTC by downregulating miR-199a-3p.

Aim: To investigate the clinical roles of LINC00152 and SNHG12 in papillary thyroid carcinoma (PTC). Methods: LINC00152 and SNHG12 expression was sought and analysis in gene expression omnibus, The Cancer Genome Atlas and GEPIA datasets. Tumor and adjacent normal tissues were collected from 97 PTC and 44 benign thyroid nodules patients. The expression was evaluated by quantitative real-time polymerase chain reaction. The association between the expression level and clinicopathologic characteristics was analyzed by χ2 test. Receiver operating characteristic curves were plotted to evaluate the diagnostic value. Results: The expression of SNHG12 and LINC00152 were significantly higher in PTC tissues than in adjacent normal tissues not only in gene expression omnibus database but the validated samples. More interesting, LINC00152 expression level was also significantly higher in PTC tissues than that in benign thyroid nodules. The upregulation of LINC00152 and SNHG12 was associated with the malignant progression of PTC. Receiver operating characteristic curve analysis also demonstrated that there was a good trend, which indicates that they may have certain diagnostic value. Conclusion: LINC00152 and SNHG12 might serve as serve as potential related molecules of PTC.

Thyroid cancers are the most common malignancy of the endocrine system; however, there is no reliable blood biomarkers for thyroid cancer diagnosis and even for aggressive and nonaggressive thyroid cancers as well as benign nodule discrimination. The present study is aimed at evaluating whether circulating microRNA (miRNA) can differentiate aggressive and nonaggressive thyroid cancer from benign thyroid nodules. In this study, we performed a multiphase, case-control study to screen serum miRNA expression profile in 100 patients with papillary thyroid cancer (PTC), 15 patients with aggressive medullary thyroid carcinoma (MTC), 91 patients with benign nodules, and 89 healthy controls using TaqMan low-density array followed by extensive reverse transcription quantitative real-time PCR validation. The results showed that the serum levels of miR-222-3p, miR-17-5p, and miR-451a were markedly increased, while miR-146a-5p, miR-132-3p, and miR-183-3p were significantly decreased in the PTC and benign nodule groups compared with the control group. There was no difference in the miRNA expression profile between the PTC group and the benign nodule group. Nevertheless, the serum levels of miR-222-3p and miR-17-5p were significantly increased in the MTC group than the benign nodule and control group. Moreover, receiver operating characteristic curve analyses demonstrated that the 2 miRNAs and their panel can accurately discriminate MTC from the benign nodule group and healthy controls. These findings indicated that the altered circulating miRNAs may discriminate PTC and benign thyroid nodules from controls, and serum miR-222-3p and miR-17-5p have the potential to serve as auxiliary tools for diagnosing more aggressive thyroid carcinomas, such as MTC.

Tsh Levels

We evaluated the preoperative serum thyrotropin (TSH) levels in 386 patients operated on for nodular thyroid disease (NTD). TSH levels for cases with final benign disease and differentiated thyroid carcinoma (DTC) were compared. No evidence of cancer was detected in 310 patients (80.3%), whereas malignancy was present in 76 cases (19.7%). Mean TSH concentration was  mU/L in benign patients and in cases with malignant lesions (). The group of malignancy was subdivided in papillary thyroid carcinoma (PTMC) versus thyroid cancer of larger size (TCLS). Mean TSH was in PTMC and in TCLS. Significant differences were found when all groups (benign, PTMC and TCLS) were compared (). However, pairwise comparisons between them showed that differences were only significant between benign and TCLS groups (). In conclusion, TSH levels were higher in patients with a final diagnosis of DTC. Moreover, it appears that there exists an increment in tumor size as a function of increment in the TSH level.
