Comprehensive transcriptomic analysis of papillary thyroid cancer: potential biomarkers associated with tumor progression

ConclusionStage I PTC patients showed large amount of expressional heterogeneity. Therefore, risk stratification based on the expressional alterations of candidate biomarkers could be an important step toward personalized management of these patients.

CLINICAL AND TRANSLATIONAL CHALLENGES IN THYROID CANCERS. Curr Med Chem. 2020 Feb 14;: Authors: Hernando J, Ros J, Arroyo A, Capdevila J Abstract Thyroid cancer is the most common endocrine malignancy and it accounts for 1% of all newly diagnosed tumors. Approximately 10% of patients with differentiated thyroid carcinomas (DTC) and 30% with medullary thyroid carcinoma (MTC) will not be cured with locoregional treatment and will develop metastatic disease. In addition, one of the most aggressive solid tumors can arise from the thyroid gland, the anaplastic thyroid carcinoma, with a median overall survi...

ConclusionConcurrent radio- and/or chemotherapy in combination with surgery seems to result in improved survival in stage IVA/B ATC, whereas this is not the case in patients with stage IVC tumors. Novel treatment regimens are urgently needed to improve the dismal prognosis of ATC.

eong Park The incidence of papillary thyroid carcinoma (PTC) has been increasing worldwide. PTC is the most common type of differentiated thyroid cancer and usually shows good prognosis. However, some PTC is driven to advanced stage by epithelial-mesenchymal transition (EMT)-mediated drug resistance, which is particularly noticeable in pediatric patients. There are limited options for systemic treatment, necessitating development of new clinical approaches. Here, we aimed to clarify genetic differences due to age of patients with PTC, and thereby aid in developing novel therapeutics. Patients with biochemically and his...

A Germline CHEK2 Mutation in a Family with Papillary Thyroid Cancer. Thyroid. 2020 Feb 11;: Authors: Zhao Y, Yu T, Chen L, Xie D, Wang F, Fu L, Cheng C, Li Y, Zhu X, Miao G Abstract Approximately 5% of all cases of PTC are inherited. However, the susceptibility gene(s) for nonsyndromic familial papillary thyroid carcinoma (FPTC) remain unclear. We performed whole genome sequencing (WGS) of peripheral-blood DNA samples from two affected family members with PTC. CHEK2 transcript expression and the protein levels of CHK2 and p53 were evaluated in the thyroid tissues from two affected members of the kindre...

ConclusionIntensive step-sectioning reveals additional micrometastases. More detailed analysis did not identify clinically significant nodal disease likely to impact the clinical course of patients in this study. Our study supports current standards of pathology specimen handling related to LN assessment and the impact on ATA ROR classification. Nonetheless, it is important for clinicians to understand their institution ’s sectioning protocol utilized to report positive and total LN counts, which could impact ATA risk stratification and denote the comprehensive nature of the LN dissection that was performed.

Pession Tallini BRAF exon 15 mutations are the most common molecular alterations found in papillary thyroid carcinoma (PTC). To date, there is no information regarding BRAF alterations in the thyroid parenchyma surrounding the tumor. To explore the early events associated with the development of PTC, we used massively parallel sequencing to investigate BRAF exon 15 in 30 PTCs and in 100 samples from the thyroid parenchyma surrounding the tumor. BRAF p.V600E was identified in 19/30 PTCs (63.3%). BRAF p.V600E mutations were identified in the tissue adjacent the PTC only in samples containing psammoma bodies. The othe...

This study is a retrospective cohort analysis of 358 PTC patients that were operated by a single surgeon in a single center. Data about the patients were extracted from the medical records.ResultsOf the patient cohort, 258 patients had TT  + PCND (42.5 ± 11.3 years) and 100 patients (41.2 ± 11.9 years) had only TT. Total number of LN extracted in the TT + PCND group was 8.1 ± 6.9. The mean number of metastatic LN were 2.2 ± 1.9. Percentage of patients that had RAI were less in the TT + PCN...

In conclusion, although CLDN1 might be correlated with LNM, it may also increase the infiltration of immune cells, including CD8+T cells and macrophages, and improve the clinical outcomes of patients with PTC. The effects of tumor purity and immune cell infiltration need to be considered in prognosis evaluation. PMID: 32045884 [PubMed - as supplied by publisher]

CONCLUSIONS: To our knowledge, this is the first documented case of gastropharyngeal anastomotic leak related to TKI use. A causal relationship is highly plausible given the previously stable anastomosis and the suspicious advent of complications within months of initiation of this new drug. While previously limited to cases of intraabdominal bowel dehiscence, this report now suggests that wound dehiscence must be considered a known side effect of TKIs throughout the gastrointestinal tract, including the gastropharynx. As such, the risk of anastomotic dehiscence should be discussed with the patient prior to starting a TKI....

Horm Metab Res DOI: 10.1055/a-1089-7870The diagnostic modalities, stratification tools, and treatment options for patients with thyroid cancer have rapidly evolved since the development of the American Thyroid Association (ATA) guidelines in 2015. This review compiles newer concepts in diagnosis, stratification tools and treatment options for patients with differentiated thyroid cancer (DTC), medullary thyroid carcinoma (MTC) and anaplastic thyroid cancer (ATC). Newer developments apply precision medicine in thyroid cancer patients to avoid over-treatment in low risk disease and un...
