Abstract Purpose To assess the impact of an [18F]FDG-PET/CT-driven diagnostic workup to rule out malignancy, avoid futile diagnostic surgeries, and improve patient outcomes in thyroid nodules with indeterminate cytology. Methods In this double-blinded, randomised controlled multicentre trial, 132 adult euthyroid patients with scheduled diagnostic surgery for a Bethesda III or IV thyroid nodule underwent [18F]FDG-PET/CT and were randomised to an [18F]FDG-PET/CT-driven or diagnostic surgery group. In the [18F]FDG-PET/CT-driven group, management was based on the [18F]FDG-PET/CT result: when the index nodule was visually [18F]FDG-positive, diagnostic surgery was advised; when [18F]FDG-negative, active surveillance was recommended. The nodule was presumed benign when it remained unchanged on ultrasound surveillance. In the diagnostic surgery group, all patients were advised to proceed to the scheduled surgery, according to current guidelines. The primary outcome was the fraction of unbeneficial patient management in one year, i.e., diagnostic surgery for benign nodules and active surveillance for malignant/borderline nodules. Intention-to-treat analysis was performed. Subgroup analyses were performed for non-Hürthle cell and Hürthle cell nodules. Results Patient management was unbeneficial in 42% (38/91 [95% confidence interval [CI], 32–53%]) of patients in the [18F]FDG-PET/CT-driven group, as compared to 83% (34/41 [95% CI, 68–93%]) in the diagnostic surgery group (p < 0.001). [18F]FDG-PET/CT-driven management avoided 40% (25/63 [95% CI, 28–53%]) diagnostic surgeries for benign nodules: 48% (23/48 [95% CI, 33–63%]) in non-Hürthle cell and 13% (2/15 [95% CI, 2–40%]) in Hürthle cell nodules (p = 0.02). No malignant or borderline tumours were observed in patients under surveillance. Sensitivity, specificity, negative and positive predictive value, and benign call rate (95% CI) of [18F]FDG-PET/CT were 94.1% (80.3–99.3%), 39.8% (30.0–50.2%), 95.1% (83.5–99.4%), 35.2% (25.4–45.9%), and 31.1% (23.3–39.7%), respectively. Conclusion An [18F]FDG-PET/CT-driven diagnostic workup of indeterminate thyroid nodules leads to practice changing management, accurately and oncologically safely reducing futile surgeries by 40%. For optimal therapeutic yield, application should be limited to non-Hürthle cell nodules. Trial registration number This trial is registered with ClinicalTrials.gov: NCT02208544 (5 August 2014), https://clinicaltrials.gov/ct2/show/NCT02208544.

Background: Fine needle aspiration cytology (FNAC) cannot differentiate between benign and malignant conditions in cytologically indeterminate thyroid lesions. Therefore, a minimum of diagnostic lobectomy is required for definitive diagnosis. The objective of this study is to identify the rate of malignancy and clinical features that may possibly predict malignancy in patients with these lesions, in Ethiopian hospitals. Methods: This was a retrospective review of the medical records of patients who underwent surgery for cytologically indeterminate thyroid lesions in three referral hospitals between September 2015 and September 2020. Results: Of 85 patients with indeterminate cytology findings, 56 (63.5%) were follicular, and 29 (34.1%) were reported to be hurthle cell neoplasms. Follicular lesions of undetermined significance (FLUS) and suspicious for follicular neoplasm were each reported in single cases (1.7%). Malignant disease was diagnosed in 19 (22.4%) of patients. A follicular variant of papillary cancer was detected in 7 (11.5%) patients. Hard nodule consistency was reported in 9 of 11 malignant lesions and 5 of 66 benign lesions. In multivariate binary logistic regression, hard nodule consistency was found to be associated with malignancy (P = 0.012, AOR = 7.28 (1.5, 34.54) 95% CI ). The ill-defined surface of a nodule was found to be associated with malignancy though the association was not statistically significant (P = 0.088, AOR = 0.162 (0.020, 1.313) 95% CI. Ultrasound evaluation of thyroid nodule was performed only in 41 (47.7%) of patients. Conclusion: The rate of malignancy in thyroid nodules with indeterminate cytology was 22.4%. The risk of malignancy was higher in patients with hard thyroid nodule consistency and ill-defined surface. Despite the established benefits of ultrasound for the evaluation of thyroid nodules, the current practice of its use in our setup is suboptimal.

Background and Objectives Follicular thyroid carcinoma (FTC) is the second common thyroid cancer which comprises about 10% of differentiated thyroid carcinoma. Hurthle cell carcinoma (HCC) is a relatively rare disease that has been classified as a subtype of FTC. However, there have been insufficient reports about these two similar thyroid cancers in South Korea due to low incidences. This study aims to present clinical features and evaluate prognostic factors of FTC and HCC.Subjects and Method We reviewed data of 189 FTC and 12 HCC patients who underwent surgery in our center from January 2000 to December 2020. Variables such as clinical characteristics, surgical method, pathologic result, post-operative treatment, survival rate and prognostic factors were included in our study.Results As for age, 67.2% of patients in FTC group and 33.3% of patients in HCC group were older than 55 years-old (p=0.017). The average tumor sizes of FTC and HCC were 2.98 and 3.1 cm, respectively. The 10-year overall survival rates of FTC and HCC were 96.5% and 100%, respectively. The 10-year disease free survival rates of FTC and HCC were 89.1% and 91.7%, respectively. Subclassification (widely invasive: p=0.036) and initial distant metastasis (p<0.001) were significant prognostic factors in FTC.Conclusion This study will be helpful for diagnosis and treatment of FTC and HCC, which are relatively rare.

Thyroid Hürthle cell carcinoma, known as thyroid eosinophilic carcinoma, is a rare pathological type of differentiated thyroid cancer (DTC), representing 3-4% of all thyroid cancers. However, given the high risk of invasion and metastasis, thyroid Hürthle cell carcinoma has a relatively poor prognosis. Traditional treatment methods have limited effects on patients with metastatic thyroid cancers. Developing a valuable therapy for advanced thyroid carcinomas is an unfilled need, and immunotherapy could represent another choice for these tumors. We herein reported the case of a patient with recurrent advanced thyroid Hürthle cell cancer and positive programmed death-ligand 1 (PD-L1) expression, who suffered tumor progression after re-surgery, radiotherapy, and targeted therapy. It is encouraging that PD-1 inhibitors in combination with GM-CSF and stereotactic body irradiation (SBRT) on metastatic disease have a significant anti-tumor effect.

Purpose: Assessment of the capabilities of the ultrasound method in the diagnostics of a rare Hurthle-cell tumor of the thyroid gland on the example of a clinical case of a patient with malignant neoplasms of independent primary multiple localizations in comparison with other research methods.Material and methods: A comprehensive study of materials from the history of the disease, the results of clinical, laboratory, instrumental, morphological research methods and their comparison with diagnostic cases from literature data.Results: Despite the full comprehensive examination of the patient, including ultrasound, MRI, PET/CT, puncture biopsy under ultrasound control, it was not possible to make the correct diagnosis before the operation. The presence of other malignant diseases in the patient’s history, the presence of altered paratracheal nodes in the same zone, and the rare occurrence of Hurthle thyroid tumors played a role.Conclusions: Hurthle-thyroid cell tumors are a rare disease, but it must always be taken into account in the diagnostic search, since even benign Hurthle tumors have a high risk of malignancy and spreading of distant metastases.

Ectopic parathyroid adenomas in thyroid tissue are uncommon (0.7 - 6%), and their oncocytic variants are exceedingly rare. We report two cases of intrathyroid parathyroid adenoma which were diagnosed as Hurthle cell adenoma on cytology. Case 1 is a 49-year-old female with a 2.4 cm hypoechoic nodule in the left lateral neck. Electrochemiluminescent immunoassay of the aspirate revealed PTH level of 422 pg/ml, conrming the presence of hyperfunctional parathyroid tissue. Subsequent resection of the left thyroid lobe revealed an enlarged intrathyroidal parathyroid. Case 2 is a 58-year-old female with a 2.1 cm hypoechoic nodule in the posterior-mid left thyroid lobe. Strong overexpression of parathyroid hormone and Chromogranin A genes and low expression of thyrocyte-related genes suggested parathyroid origin of the cells sampled. MEN1 mutation and multiple copy number alterations indicated the neoplastic nature of the nodule. Parathyroid oxyphil cells and oncocytic thyrocytes share cytomorphological ndings and distinguishing them by cytology alone is challenging, especially when the targeted lesion is intrathyroidal. Distinguishing intrathyroid oncocytic parathyroid adenoma from oncocytic thyroid follicular lesions has signicant clinical implications as Bethesda-IV category lesions have 20%–30% risk of malignancy. While stippled chromatin or intracytoplasmic fat vacuoles may be suggestive of parathyroid origin, these are not specic. Classifying the origin of a nodule as parathyroid vs thyroid rests upon the detection of PTH in aspirate material by ECL, immunocytochemistry or next-generation sequencing. In parathyroid aspirates, PTH level 100 pg/mL is suggestive of the presence of PTH-secre ≥ ting tissue at the site biopsied or along the needle track.
