Comparative outcomes of ultrasound-guided radiofrequency ablation vs. microwave ablation for patients with T1N0M0 papillary thyroid carcinoma: a retrospective cohort study.
Eur Radiol
January 2025
Department of Ultrasound, First Medical Center, Chinese PLA General Hospital, No. 28 Fuxing Road, Haidian District, 100853, Beijing, China.
Objective: To compare the clinical outcomes between radiofrequency ablation (RFA) and microwave ablation (MWA) for the treatment of T1N0M0 papillary thyroid carcinoma (PTC) in a large cohort.
Materials And Methods: This retrospective study included 1111 patients with solitary T1N0M0 PTC treated with RFA (n = 894) or MWA (n = 215) by experienced physicians. A propensity score matching was used to compare disease progression, including lymph node metastases (LNM), recurrent tumors and persistent tumors, recurrence-free survival (RFS), volume reduction ratio (VRR), and complications between the RFA and MWA groups.
Somatic copy number deletion of chromosome 22q in papillary thyroid carcinoma.
Eur Thyroid J

Deletion of the long q arm of chromosome 22 (22qDEL) is the most frequently identified recurrent somatic copy number alteration (SCNA) observed in papillary thyroid carcinoma (PTC). Since its role in PTC is not fully understood, we conducted a pooled analysis of genomic characteristics and clinical correlates in 1094 primary tumors from four published PTC genomic studies. The majority of PTC with 22qDEL exhibited arm-level loss of heterozygosity (86%); nearly all PTC with 22qDEL had losses in 22q12 and 13, which together constitute 70% of the q arm.

December 2024
Faculty of Medicine, Nursing, and Health Sciences, Monash University, Clayton, Victoria, Australia.
Objective: This systematic review seeks to evaluate the prevalence of local symptoms in patients with benign thyroid disease as described in the literature.
Data Sources: A literature search was conducted across PubMed, Embase, Medline, and Cochrane databases.
Review Methods: Crude symptom prevalence was obtained by addition of data across studies that reported local symptoms, and adjusted symptom frequency was calculated using a random effects model.
Arrival-Time Parametric Imaging in Contrast-Enhanced Ultrasound for Thyroid Nodule Differentiation.
Med Sci Monit
December 2024
Department of Ultrasound Diagnosis, General Hospital of Northern Theater Command, Shenyang, Liaoning, China.
BACKGROUND Solitary thyroid nodules present a challenge in differentiating between benign and malignant conditions using ultrasound (US). Arrival time parameter imaging (At-PI) following contrast-enhanced ultrasound (CEUS) can effectively visualize the vascular architectural patterns of the nodules, providing valuable diagnostic information. This study aimed to explore the application value of At-PI in differentiating thyroid nodules, specifically focusing on a sample of 127 cases.

Thyroid
December 2024
Oncology Center, Oswaldo Cruz German Hospital, São Paulo, Brazil.
Autonomously functioning thyroid nodules (AFTNs) represent ∼5% of all thyroid nodules and often necessitate definitive treatments such as surgery or radioiodine (I), both of which have inherent risks. Radiofrequency ablation (RFA) has emerged as an effective and safe therapeutic option for managing AFTNs. This study aims to assess the effectiveness and safety of RFA for solitary AFTNs in various countries across Latin America.
