Abstract Introduction Hashimoto thyroiditis (HT) shares many characteristics with papillary thyroid carcinoma (PTC), and some studies show that, when associated, PTC is diagnosed mostly with smaller lesions and multifocal pattern. Objective To evaluate the relationship between HT and PTC. Methods A retrospective study of 155 patients who underwent total thyroidectomy from 2009 to 2015. Demographical, clinical and ultrasonographical data, as well as anatomopathological findings were evaluated. Results There were signs of thyroidits in 35 patients, and 114 patients had a unifocal disease. There was no statistical significance between the variables studied and thyroiditis. However, when compared with the occurrence of unifocal or multifocal lesions, there was statistical significance regarding age (p = 0.038) and mass (p = 0.031). There was no direct relationship between thyroiditis and multifocality (p = 0.325) nor between thyroiditis and cervical extension of the disease (p = 0.300 e p = 0.434). Conclusion There was no relationship between thyroiditis and multifocality in cases of PTC.

Abstract Background : m6A methylation-related long non-coding RNAs (lncRNAs) play a significant role in the progression of various tumors and can be used as prognostic markers. However, whether m6A-related lncRNAs also play the same function as prognostic markers in papillary thyroid carcinoma (PTC) remains unclear. Methods : Consensus cluster analysis was performed to divide PTC samples obtained from The Cancer Genome Atlas database into two clusters according to the expression of m6A-related lncRNAs. Then, the least absolute shrinkage and selection operator (LASSO) regression analysis was performed to create and verify a prognostic model. Furthermore, the relationship among risk scores, clusters, programmed death-ligand 1 (PD-L1), tumor microenvironment (TME), clinicopathological characteristics, immune infiltration, immune checkpoint, and tumor mutation burden (TMB) was analyzed. In addition, a nomogram was created, and subsequently, the drug sensitivity of lncRNAs in the prognostic model was analyzed. Finally, the relationship between these lncRNAs and prognosis in pan-cancer was investigated. Results: The prognosis, RAS, BRAF, M, and TME were found to be different in two clusters. The prognostic model included three lncRNAs: PSMG3-AS1 , BHLHE40-AS1 , and AC016747.3 . The risk score was associated with clusters, PD-L1, tumor microenvironment, clinicopathological characteristics, immune cell infiltration, immune checkpoint, and TMB, and thus, risk score was confirmed as useful prognostic indicators. Differentially expressed lncRNAs are involved in many malignancies and can be identified as cancer prognostic makers. Conclusion : According to our research, we can regard m6A-related lncRNAs involved in the procession of PTC as a biomarker of PFS for PTC patients, and pan-cancer.

Clinical studies have shown similarities in the genetic background and biological functional characteristics between Hashimoto’s thyroiditis (HT) and papillary thyroid carcinoma (PTC), and that HT may increase risks of PTC. Here, we set to determine the gene expression specificity of HT and PTC by screening related genes or co-expressed genes and exploring their genetic correlation. Referencing the Oncomine database, HT-related genes were discovered to be expressed in many different types of thyroid cancer, such as TSHR that is highly expressed in thyroid cancer. An in-depth genetic analysis and verification of 35 cancer and paracancerous tissue pairs from patients with thyroid cancer, and 35 tissues and blood cells pairs from patients with Hashimoto’s thyroiditis was conducted. Gene chip technology research showed that TSHR, BACH2, FOXE1, RNASET2, CTLA4, PTPN22, IL2RA and other HT-related genes were all expressed in PTC, in which TSHR was significantly over-expressed in PTC patients sensitive to radioactive iodine therapy, while BACH2 was significantly under-expressed in these patients. The biologically significant candidate Tag SNP highlighted from HT-related genes was screened by the high-throughput detection method. Somatic mutations in patients with HT and PTC were detected by target region capture technique, and 75 mutations were found in patients with HT and PTC. The upstream regulatory factors of the different genes shared by HT and PTC were analyzed based on Ingenuity Pathway Analysis (IPA), and it was found that HIF-1α and PD-L1 could be used as important upstream regulatory signal molecules. These results provide a basis for screening key diagnostic genes of PTC by highlighting the relationship between some HT-related genes and their polymorphisms in the pathogenesis of PTC.

The Relationship

To investigate the relationship between the methylation of death-associated protein kinase (DAPK) promoter and gene inactivation in papillary thyroid carcinoma, the technique of methylation-specific polymerase chain reaction (PCR (MSP)) was applied to detect the methylation status of DAPK gene promoter in 70 cases of papillary thyroid carcinoma (study group) and in 50 cases of corresponding adjacent tissues (control group). Immunohistochemical method was used to detect the protein expression; besides, the relationship of DAPK methylation and gene inactivation with pathological factors of papillary thyroid cancer was analyzed. The methylation rate of DAPK was 16% (8/50) in the control group and 71.4% (50/70) in the study group with the difference being statistically significant (χ2 = 19.724, P < 0.01). The methylation of DAPK gene promoter was not associated with age, sex, tumor size, TNM stage, and thyroid capsular infiltration in the study group with papillary thyroid carcinoma ( P > 0.05), but was associated with lymph node metastasis ( P < 0.05). Spearman’s rank correlation analysis showed that the methylation of DAPK promoter was negatively correlated with the expression of DAPK (r = −0.793, P < 0.01). The methylation of CpG island in the promoter region of DAPK gene can lead to gene inactivation and may be involved in the occurrence of papillary thyroid carcinoma.

The Relationship

Background It is important to predict lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC) preoperatively; however, the relationship between the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS) score and cervical LNM remains unclear. Purpose To evaluate the association between the ACR TI-RADS score and cervical LNM in patients with PTC. Material and Methods This retrospective study consisted of 474 patients with 548 PTCs. Cervical LNM including central LNM (CLNM) and lateral LNM (LLNM) were confirmed by pathology. Univariate and multivariate analyses were performed to investigate the risk factors of CLNM and LLNM. Results Multivariate logistic regression analyses indicated that younger age and multifocality were risk factors for CLNM in PTCs with TR5. In addition, younger age, larger tumor size, and Hashimoto’s thyroiditis (HT) were risk factors for LLNM in PTCs ≥ 10 mm with TR5. In PTCs with TR4, ACR TI-RADS scores 5–6 conferred risks for LNM. In PTCs ≥ 10 mm with TR5, ACR TI-RADS scores ≥9 were risk factors for LLNM. Conclusion A higher ACR TI-RADS score is a predictor for cervical LNM in PTCs with TR4 and PTCs ≥ 10 mm with TR5.
