The role of radioactive iodine in the management of patients with differentiated thyroid cancer – An oncologic surgical perspective

Publication date: Available online 9 January 2020Source: European Journal of Surgical OncologyAuthor(s): I.J. Nixon, J.P. Shah, M. Zafereo, R.S. Simo, I.D. Hay, C. Suárez, P. Zbären, A. Rinaldo, A. Sanabria, C. Silver, A. Mäkitie, V. Vander Poorten, L.P. Kowalski, A.R. Shaha, G.W. Randolph, A. FerlitoAbstractWith improved understanding of the biology of differentiated thyroid carcinoma its management is evolving. The approach to surgery for the primary tumour and elective nodal surgery is moving from a “one size -fits-all” recommendation to a more personalised approach based on risk group stratification. With this selective approach to initial surgery, the indications for adjuvant radioactive iodine (RAI) therapy are also changing. This selective approach to adjuvant therapy requires understanding by the entire treatment team of the rationale for RAI, the potential for benefit, the limitations of the evidence, and the potential for side-effects.This review considers the evidence base for the benefits of using RAI in the primary and recurrent setting as well as the side-effects and risks from RAI treatment. By considering the pros and cons of adjuvant therapy we present an oncologic surgical perspective on selection of treatment for patients, both following pre-operative diagnostic biopsy and in the setting of a post-operative diagnosis of malignancy.

This study aimed to evaluate fertility in female survivors of childhood DTC by assessing various reproductive characteristics combined with anti-Müllerian hormone (AMH) levels (a marker of ovarian reserve). Methods. Female survivors of childhood DTC, diagnosed at ≤18 years of age between 1970 and 2013 were included. Survivors were excluded when follow-up time was less than 5 years or if they developed other malignancies before or after diagnosis of DTC. Survivors filled out a questionnaire regarding reproductive characteristics (e.g. age at menarche and menopause, pregnancies, pregnancy outcomes, need for assisted ...

Authors: Yang C, Xu W, Gong J, Liu Z, Cui D Abstract To characterize the somatic alterations of papillary thyroid carcinomas (PTC) in Chinese patients, we performed the next-generation-sequencing (NGS) study of the tumor-normal pairs of DNA and RNA samples extracted from 16 Chinese PTC patients. The whole genome sequencing (WGS) and transcriptome sequencing (RNA-seq) were conducted for 6 patients who were either current or former smokers and the whole exome sequencing (WES) and RNA-seq were conducted for another 10 patients who were never smokers. The NGS data were analyzed to identify somatic alteration events tha...

In this study, we employed network-based integrative analyses of FTC and benign follicular thyroid adenoma (FTA) lesion transcriptomes to identify key genes and pathways that differ between them. We first analysed a microarray gene expression dataset (Gene Expression Omnibus GSE82208, n = 52) obtained from FTC and FTA tissues to identify differentially expressed genes (DEGs). Pathway analyses of these DEGs were then performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) resources to identify potentially important pathways, and protein-protein interactions (PPIs) were examined to identify path...

ConclusionsThese findings suggest that CDK1, CCNB2, BUB1B, CDC20, RRM2, CHEK1 and CDC45 may serve as novel diagnosis biomarkers and potential therapeutic target for ATC.

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...
