Differentiated thyroid cancer in adolescents - does extent of disease at presentation differ with age?

Objectives: The authors sought to assess whether the age of 18 reflects a true pathological inflection point that justifies transitioning between pediatric and adult paradigms of care with differentiated thyroid cancer (DTC).

Methods: A retrospective chart review was conducted for patients aged 12-24 undergoing hemithyroidectomy or total thyroidectomy for papillary or follicular thyroid carcinoma from 2010 to 2020.

Results: A total of 153 patients receiving surgery for DTC were assessed for pathological stage, nodal metastasis, and thyroid neoplasm characteristics.

Characterization of Somatostatin Receptor 2 Gene Expression and Immune Landscape in Sinonasal Malignancies.

Olfactory neuroblastoma (ONB), sinonasal undifferentiated carcinoma (SNUC), and sinonasal neuroendocrine carcinoma (SNEC) are rare malignancies arising from the sinonasal tract with limited therapeutic options. The expression of the somatostatin receptor 2 gene (), which is expressed in other neuroendocrine neoplasms and is therapeutically actionable, has been reported in these tumors. Here, we analyzed gene expression and its associations with genomic features, established biomarkers predicting of immune response, and the tumor immune microenvironment in a cohort of ONB, SNUC, and SNEC tumor samples (26, 13, and 8 samples, respectively) from a real-world database.

The Potential Utility of RAS Q61R Immunohistochemistry as a Screening Tool in Pre-operative Fine Needle Aspirates of Medullary Thyroid Carcinoma.

Medullary thyroid carcinoma (MTC) can either be sporadic, often via mutually exclusive RET or RAS alterations, or inherited via a RET germline alteration. Germline testing is recommended for all patients diagnosed with MTC. RAS p.

Risk stratification of ThyroSeq results in indeterminate thyroid lesions: A single-institution experience of clinicopathologic correlation with cytologic findings.

Background: ThyroSeq offers the opportunity to stratify the risk of malignancy (ROM) in the characterization of indeterminate thyroid nodules, especially those categorized as atypia of undetermined significance (AUS). However, whether ThyroSeq interpretations correlate with cytologic features, management, and surgical outcome remains unclear.

Methods: Thyroid fine-needle aspiration specimens categorized as AUS and follicular neoplasm (FN) from 2017 to 2021 were identified from a cytology database search.
