Clinically Relevant Prognostic Parameters in Differentiated Thyroid Carcinoma.

Endocr Pathol 2018 Dec;29(4):357-364

Department of Pathology, Brigham and Women's Hospital and Harvard Medical School, 75 Francis Street, Boston, MA, 02115, USA.

Although differentiated thyroid carcinomas typically pursue an indolent clinical course, it is important to identify the subset of tumors that are most likely to behave aggressively so that patients with these tumors are counseled and treated appropriately. Extent of disease is fundamental to the prognostication for differentiated thyroid carcinoma; however, there are additional histologic features of the tumor separate from extent of disease that have been shown to affect clinical course. This review will start with a discussion of aggressive variants of papillary thyroid carcinoma, move to the prognostic significance of vascular invasion in follicular thyroid carcinoma, and finish with a discussion of Hürthle cell carcinoma, with an emphasis on why it is not considered a subtype of follicular thyroid carcinoma in the 2017 WHO Classification of Tumors of Endocrine Organs.

J Cytol 2018 Jul-Sep;35(3):131-138

Department of Pathology, Faculty of Medicine, Kuwait University, and Cytology Unit, Mubarak Al-Kabeer Hospital, Kuwait.

Synthesis and storage of thyroglobulin as well as synthesis of thyroid hormones and their release into the circulation are important functions of thyroid, which were studied in fine needle aspiration (FNA) smears from thyroid lesions. Evidence of thyroglobulin synthesis was demonstrated in neoplastic and nonneoplastic follicular cells, especially in Hürthle cells, in the form of colloid inclusions. Whereas the pinocytic vesicles containing colloid at the luminal end of in nonneoplastic and neoplastic follicular cells indicated engulfment of colloid for synthesis of thyroid hormones (T and T), the marginal vacuoles (MVs) (fire-flare appearance) at the basal aspects of follicular cells suggested their release on way to the interfollicular capillaries.

Department of Ultrasound, Beijing Friendship Hospital, Capital Medical University, Beijing 100050, P.R. China.

HRas proto-oncogene () is one of the most commonly mutated genes in thyroid cancer, with mutations frequently occurring in the follicular and Hurthle cell subtypes. However, the contribution of mutations in to papillary thyroid carcinoma (PTC) progression and the tall-cell variant (TCV) is poorly understood. The aim of the present study was to investigate the somatic genetic variants present in in patients with PTC, and to investigate the association of these mutations with PTC. Read More

IS MEASUREMENT OF CIRCULATING TUMOR DNA OF DIAGNOSTIC USE IN PATIENTS WITH THYROID NODULES?

Endocr Pract 2018 May 2;24(5):453-459. Epub 2018 Mar 2.

Objective: Circulating tumor DNA (ctDNA), a subset of cell-free DNA (cfDNA), is a potential biomarker for thyroid cancer. We determined the performance of a ctDNA panel for detecting thyroid malignancy in patients with thyroid nodules.

Methods: Sixty-six patients with thyroid nodules without a prior history of cancer enrolled in a prospective, 1-year study in which blood was drawn for ctDNA analysis prior to undergoing fine-needle aspiration biopsy (FNAB) of thyroid nodules. Read More

Different qualifiers of AUS/FLUS thyroid FNA have distinct BRAF, RAS, RET/PTC, and PAX8/PPARg alterations.

Cancer Cytopathol 2018 May 22;126(5):317-325. Epub 2018 Feb 22.

Department of Public Health, Federico II University of Naples, Naples, Italy.

Background: The Bethesda System for Reporting Thyroid Cytopathology category of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) includes fine-needle aspiration (FNA) specimens that cannot straightforwardly be classified as benign or malignant. To determine whether morphological subcategorization based on atypia qualifiers and molecular testing could improve malignancy risk stratification of AUS/FLUS patients, this study assessed the correlation between these qualifiers and the molecular alterations commonly harbored by thyroid neoplasms.

Methods: A total of 162 AUS/FLUS cases were subcategorized by atypia qualifiers (Hürthle cell changes, architectural atypia, and cytologic atypia [CyA]) and were tested for BRAF, N-H-KRAS, RET/PTC, and paired box 8 (PAX8)/peroxisome proliferator activated receptor γ (PPARg) mutations. Read More

Preoperative Cytologic Diagnosis of Warthin-like Variant of Papillary Thyroid Carcinoma.

J Pathol Transl Med 2018 Mar 12;52(2):105-109. Epub 2018 Feb 12.

Department of Pathology, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.

Background: Warthin-like variant of papillary thyroid carcinoma (WLV-PTC) is a relatively rare variant of papillary thyroid carcinoma with favorable prognosis. However, preoperative diagnosis using fine-needle aspiration (FNA) specimens is challenging especially with lymphocytic thyroiditis characterized by Hürthle cells and lymphocytic background. To determine a helpful cytological differential point, we compared WLV-PTC FNA findings with conventional papillary thyroid carcinoma with lymphocytic thyroiditis (PTC-LT) and conventional papillary thyroid carcinoma without lymphocytic thyroiditis (PTC) regarding infiltrating inflammatory cells and their distribution.

The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features on the rate of malignancy for atypia of undetermined significance subcategories.

Cancer Cytopathol 2018 May 9;126(5):309-316. Epub 2018 Feb 9.

Department of Pathology, The Johns Hopkins Hospital, Baltimore, Maryland.

Background: The recent revision in terminology, with noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) replacing noninvasive follicular variant of papillary thyroid carcinoma, has reclassified the clinically indolent tumor as nonmalignant. The objective of this study was to evaluate the impact of this change on the rate of malignancy (ROM) for subcategories of an atypia of undetermined significance (AUS) diagnosis on fine-needle aspiration (FNA) cytology.

Methods: Consecutive thyroid FNAs interpreted as AUS over a period of 4 years were retrospectively analyzed. Read More
