Context: Follicular thyroid cancer (FTC) is classified into minimally invasive (miFTC), encapsulated angioinvasive (eaFTC), and widely invasive (wiFTC) subtypes, according to the 2017 World Health Organization (WHO) guidelines. The genetic signatures of these subtypes may be crucial for diagnosis, prognosis, and treatment, but have not been described. Objective: Identify and describe the genetic underpinnings of subtypes of follicular thyroid cancer. Methods: Thirty-nine tumors, comprising 12 miFTCs, 17 eaFTCs, and 10 wiFTCs were whole-exome sequenced and analyzed...

Follicular-patterned tumors of the thyroid gland are characterized by a predominantly follicular growth pattern. They frequently harbor RAS mutations, not BRAF mutations. Technological advances in molecular testing have discovered novel RAS-type mutations. However, clinical significance of these mutations remains unknown. We investigated the prevalence and clinical impact of mutations of BRAF, NRAS, HRAS, KRAS, EZH1, EIF1AX, and TERT genes by Sanger sequencing in a series of 201 follicular-patterned thyroid tumors including follicular adenoma (n=40), Hürthle cell adenoma (n=54), noninvasive follicular thyroid neoplasms with papillary-like nuclear features (n=50), follicular thyroid carcinoma (n=40), Hürthle cell carcinoma (n=10), and poorly differentiated thyroid carcinoma arising in a well differentiated follicular neoplasm (n=7), and 120 classic papillary carcinoma...

Background: Preablative stimulated thyroglobulin (ps-Tg) is an important investigation in the follow-up of patients with Differentiated thyroid cancer(DTC) after surgery. Levels of ps-Tg >2-10 ng/ml have been suggested to predict metastasis to cervical and extracervical sites. There is still debate on the need for routine iodine whole-body scan (131 I WBS) in the management of low-to-intermediate-risk DTC patients. Objective: We analyzed our data of patients with DTC who underwent total thyroidectomy to discuss the predictability of ps-Tg on metastatic disease on the 131 I WBS...

BACKGROUND: The prognostic variability of thyroid carcinomas has led to the search for accurate biomarkers at the molecular level. Follicular thyroid carcinoma (FTC) is a typical example of differentiated thyroid carcinomas (DTC) in which challenges are faced in the differential diagnosis. METHODS: We used high-throughput paired-end RNA sequencing technology to study four cases of FTC with different degree of capsular invasion: two minimally invasive (mFTC) and two widely invasive FTC (wFTC)...

Ultrasonography is pivotal in triage thyroid biopsy in the era after the identification of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This pictorial essay illustrates the pathologic basis of the sonographic features that distinguish NIFTP from thyroid cancers. In this study, we present the correlations of ultrasonography to ×1 histopathology to assess shape and margin characteristics. Markedly hypoechoic nodules correlate to microfollicular/solid nodules, while isoechoic/hyperechoic thyroid nodules correlate to normofollicular/macrofollicular nodules...

The diagnostic and clinical approaches to follicular-patterned thyroid neoplasms often create dilemmas for pathologist and clinicians. The molecular analysis of these tumors could be a useful tool to overcome diagnostic limitations. The most frequent molecular alterations are point mutations of RAS family genes. Nevertheless, other molecular markers should be taken into account for their prognostic role, as BRAF mutations and the recently described telomerase reverse transcriptase (TERT) promoter mutation. We investigated the prevalence and the possible role of TERT promoter, BRAF, and RAS mutations in a series of low-risk well-differentiated follicular-patterned thyroid neoplasms...

AIMS: Paediatric follicular thyroid carcinomas are uncommon, and their clinicopathological features and molecular profiles are still unknown. In the present study, we aimed to investigate the clinicopathological aspects of a large series of follicular thyroid carcinomas (FTCs) in paediatric patients and to analyse the point mutations in codons 12, 13 and 61 of NRAS, HRAS and KRAS genes and the rearrangements of PAX8-PPARG. METHODS AND RESULTS: A total of 41 paediatric FTCs less than 21 years of age were enrolled into the present study...

BACKGROUND: Follicular thyroid cancer is the second most common thyroid cancer, accounting for 10%-15% of all cases. Follicular thyroid carcinomas (FTCs) can be classified into two subtypes: classic (C), which exhibit both vascular and capsular invasion and minimally invasive (MI), which only has limited capsular invasion. Both types, like most well-differentiated thyroid cancers, are traditionally treated the same: a completion thyroidectomy usually followed by radioiodine ablation. We hypothesize that MI-FTC may behave more like a benign follicular adenoma rather than C-FTC and may not require total thyroidectomy and radioiodine...

Follicular thyroid carcinoma (FTC) and benign follicular adenoma (FA) are indistinguishable by preoperative diagnosis due to their similar histological features. Here we report the first RNA sequencing study of these tumors, with data for 30 minimally invasive FTCs (miFTCs) and 25 FAs. We also compared 77 classical papillary thyroid carcinomas (cPTCs) and 48 follicular variant of PTCs (FVPTCs) to observe the differences in their molecular properties. Mutations in H/K/NRAS, DICER1, EIF1AX, IDH1, PTEN, SOS1, and SPOP were identified in miFTC or FA...

The procedure guideline for radioiodine therapy of differentiated thyroid cancer (version 4) was developed in the consensus of a representative expert group. This fulfils the level S1 (first step) within the AWMF classification of Clinical Practice Guidelines (AWMF, Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, Germany). This procedure guideline completed the guideline for surgical management of thyroid cancer (level S2) with the aspects from nuclear medicine. Controversies over ablative radioiodine therapy in small papillary thyroid cancers and in minimally invasive follicular cancer without angioinvasion, over empirical standard doses for ablative radioiodine therapy, and over the kind of TSH-stimulation were described and the guideline formulated a corridor of good clinical practice...

BACKGROUND: Thyroperoxidase (TPO) is a membrane-bound protein essential for the production of thyroid hormones; because of this, TPO expression may be impaired in selected thyroid diseases. The goal of this study is to analyze TPO immune expression in differentiated thyroid cancer, and to determine whether TPO has any prognostic value. METHODS: A total of 139 patients who required surgery due to a thyroid nodule with signs or symptoms suspicious for malignancy during their physical, ultrasound and/or cytology examination were consecutively selected for the study...

The strategy for surgical treatment of thyroid cancer differs depending on the histopathological type. In papillary thyroid cancer, which accounts for most cases of thyroid cancer, total thyroidectomy is recommended in high-risk cases with tumors of more than 5 cm or with N1, EX2, or M1 tumors in Japan. On the other hand, ipsilateral lobectomy is performed for low-risk cases with T1N0M0. Our department has also added a treatment policy for the prognostic factor, age. Prophylactic lymph node dissection is performed in the central neck region but is not recommended in the lateral neck region...

Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer after papillary carcinoma. Based on the extent of invasion, it has been classified into minimally and widely invasive subtypes. The minimally invasive type usually grows slowly and is clinically indolent but in rare cases has an aggressive behavior with distant metastases. The lungs and bones are the most common sites of metastasis. The literature mentions very few cases of scalp metastases. We report an unusual case of minimally invasive FTC with multiple scalp and bone metastases as the initial presenting complaint...

Follicular thyroid carcinoma is the second most common type of thyroid cancer, and its incidence has increased dramatically in recent years. Although it typically presents as a thyroid nodule, it can spread to distant sites via hematogenous dissemination. Spinal cord compression complicating thyroid carcinoma is rare with only few cases reported in the literature. This case illustrates a minimally invasive follicular carcinoma that showed such an aggressive behavior, and thus the importance of considering metastatic thyroid carcinoma in the differential diagnosis of chronic back pain, which may possibly progress to spinal cord compression carrying severe morbidity...

OBJECTIVE: The primary purpose of this study was to validate the proposed modified 2009 American Thyroid Association Risk Stratification System (M-2009-RSS) in patients with thyroid cancer and to compare the findings with those of the 2009 ATA Risk of Recurrence (2009 ATA-RR) and the Ongoing Risk of recurrence system. The secondary purpose was to assess which risk stratification system had the best predictive value to foresee the probability of structural incomplete response or the no evidence of disease (NED) status at the end of follow-up...

BACKGROUND: The solid variant of papillary thyroid carcinoma (SVPTC) comprises approximately 3% of thyroid cancers, and there are conflicting reports about its behavior in the literature. The cytology of SVPTC is limited to 3 single case reports, a review article, and a monograph. We present the first cytologic study of SVPTC. METHODS: Fine-needle aspiration smears obtained with ultrasound guidance from 13 patients with histologically pure SVPTC were reviewed, and the cytologic features recorded...

Follicular thyroid carcinoma is the second most common type of thyroid cancer, and its incidence has increased dramatically in recent years. Although it typically presents as a thyroid nodule, it can spread to distant sites via hematogenous dissemination. Bone metastasis is diagnosed clinically in 2%-13% of patients with differentiated thyroid cancer; nevertheless spinal cord compression complicating thyroid carcinoma is rare and only few cases has been reported in the literature. This case illustrates a strange case of a minimally invasive follicular carcinoma that showed an aggressive behavior, and thus the importance of considering metastatic thyroid carcinoma in the differential diagnosis of chronic back pain progressing to spinal cord compression carrying a severe morbidity...
