Special Issue Information

Dear Colleagues,

The Special Issue "Thyroid Nodule: Updates on the Molecular Mechanism and Diagnosis" focuses on the growing importance of characterizing thyroid nodules with maximum accuracy.

The accuracy certainly derives from the knowledge of the molecular mechanisms underlying formation of thyroid nodules and from the use of more precise diagnostic tools.

The incidence of thyroid cancer is increasing rapidly worldwide, although its mortality rate remains flat. Thyroid nodules occur commonly in the general population, mostly as incidental findings at ultrasound evaluation, which is the first examination method used for neck imaging. However, although ultrasound is an established and very sensitive method for detecting thyroid nodules, and superior to clinical physical palpation, it has a relatively low diagnostic performance when it comes to differentiating between benign and malignant nodules.

In recent years, several studies have proposed the potential use of new ultrasound techniques through a multiparametric evaluation by using new methods, such as CEUS (contrast-enhanced ultrasound) and, especially, USE (US elastography) to increase the accuracy of baseline ultrasound. This is used in order to improve the non-invasive diagnostic power of thyroid nodules, avoiding invasive investigations, such as feed needle aspiration cytology (FNAC) or biopsy, which are often necessary.

The purpose of this Special Issue is to analyze the molecular mechanisms underlying the formation of thyroid nodules and to take stock of the updates present in the most recent literature regarding a more precise instrumental diagnosis, combining new experiments.

Familial non-medullary thyroid carcinoma (FNMTC) accounts for 3% to 9% of all thyroid cancer cases, yet its genetic mechanisms remain unknown. Our study aimed to screen and identify novel susceptibility genes for FNMTC. Whole-exome sequencing (WES) was conducted on a confirmed FNMTC pedigree, comprising four affected individuals across two generations. Variants were filtered and analyzed using ExAC and 1000 Genomes Project, with candidate gene pathogenicity predicted using SIFT, PolyPhen, and MutationTaster. Validation was performed through Sanger sequencing in affected pedigree members and sporadic patients (TCGA database) as well as general population data (gnomAD database). Ultimately, we identified the mutant PPP4R3A (NC_000014.8:g.91942196C>T, or NM_001366432.2(NP_001353361.1):p.(Asp409Asn), based on GRCH37) as an FNMTC susceptibility gene. Subsequently, a series of functional experiments were conducted to investigate the impact of PPP4R3A and its Asp409Asn missense variant in thyroid cancer. Our findings demonstrated that wild-type PPP4R3A exerted tumor-suppressive effects via the Akt-mTOR-P70 S6K/4E-BP1 axis. However, overexpression of the PPP4R3A Asp409Asn mutant resulted in loss of tumor-suppressive function, ineffective inhibition of cell invasion, and even promotion of cell proliferation and migration by activating the Akt/mTOR signaling pathway. These results indicated that the missense variant PPP4R3A Asp409Asn is a candidate susceptibility gene for FNMTC, providing new insights into the diagnosis and intervention of FNMTC. Full article

The endotracheal tube (ETT) with laryngeal adhesive electrodes for intraoperative neural monitoring (IONM) may be related to laryngopharyngeal complications, such as postoperative sore throat (POST), hoarseness, and coughing. We aimed to evaluate the effects of the ETT with laryngeal adhesive electrodes for IONM on the occurrence of laryngopharyngeal complications during thyroidectomy. In this retrospective study, we included 176 patients who underwent thyroidectomy for thyroid cancer between September 2020 and February 2021. The patients were categorized into control (n = 108) and IONM (n = 68) groups. Patients in the IONM group were intubated with the ETT with surface electrodes. Characteristics of the patients and surgery, perioperative variables, and laryngopharyngeal complications, including POST, hoarseness, and cough, were evaluated. The severity and incidence of POST were comparable between the two groups on postoperative days 0, 1, and 2 (p = 0.103, 0.386, and 0.056, respectively). Furthermore, no significant differences were observed in the occurrence of postoperative hoarseness and cough between the groups. The ETT with laryngeal adhesive electrodes for IONM during thyroidectomy did not affect the incidence and severity of postoperative laryngopharyngeal complications, including POST, hoarseness, and cough. Further prospective, double-blinded, randomized clinical trials are required to gain a clearer understanding. Full article
