Abstract

The optimal extent of surgery needed for isthmic papillary thyroid carcinoma (PTC) is not well-defined, although total thyroidectomy is usually recommended. This study aimed to evaluate the efficacy of isthmusectomy in the surgical treatment of isthmic PTC. Materials and Methods: We retrospectively studied 121 patients who underwent thyroidectomy with or without central neck dissection (CND) for single isthmic PTC from January 2003 to June 2019. We excluded patients who were clinically suspected to have clinically positive cervical lymph node metastasis and gross extrathyroidal extension or to have cancers at sites other than the thyroid isthmus. Patients were divided into three groups according to the extent of thyroidectomy—total thyroidectomy, lobectomy with isthmusectomy (the lobectomy group), and isthmusectomy. Clinical and pathologic characteristics, surgical outcomes, recurrence rate, and survival were analyzed. Results: Of 121 isthmic PTC patients, 28 were men and 93 were women. Total thyroidectomy, lobectomy with isthmusectomy, and isthmusectomy were performed in 70 (57.8%), 40 (33.1%), and 11 (9.1%) patients, respectively. Prophylactic CND was performed in 104 (86%) patients. In a subgroup analysis, patients who underwent total thyroidectomy showed higher postoperative hypoparathyroidism (p < 0.001) than those who underwent lobectomy and isthmusectomy. However, there were no differences in the recurrence rate or survival between the three groups. Conclusion: Thyroid isthmusectomy may be effective in the surgical treatment of small single isthmic PTC. Further studies are necessary to verify this result. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: We aimed to compare the efficacy of ultrasound-guided core-needle biopsy (CNB) with repeat fine-needle aspiration (rFNA) cytology in thyroid nodules with inconclusive results in initial fine-needle aspiration cytology. Methods: We studied 402 patients who required a repeat biopsy of thyroid nodules using ultrasound-guided CNB (n = 192) or rFNA (n = 210) because of inconclusive results in initial FNA, corresponding to categories I, III, and IV of the Bethesda System for Reporting Thyroid Cytopathology. If repeat biopsy results were benign (category II), suspicious malignancy (category V), or malignancy (category VI), they were defined as "diagnostic results". The diagnostic yield and performances of repeat biopsy were analyzed and compared between the rFNA and CNB groups. Results: The diagnostic results were obtained significantly higher in the CNB group than in the rFNA group (72.4% vs. 52.4%; P < 0.001). In the subgroup analysis, the diagnostic results were significantly higher in the CNB group than in the rFNA group for patients of categories I and III (P < 0.001 in both) in initial FNA. However, in patients with category IV nodules, there were no significant differences in diagnostic results between the two groups (P = 0.46). Conclusion: Compared to rFNA, ultrasound-guided CNB is useful and effective as a repeat biopsy option for thyroid nodules with non-diagnostic results (category I) and atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS) (category III) in initial FNA.

Abstract

Objectives/hypothesis: Ultrasound-guided fine-needle aspiration cytology (US-FNAC) is a well-established procedure performed to establish the diagnosis of Kikuchi-Fujimoto disease (KFD). Ultrasound-guided core needle biopsy (US-CNB) is an alternative diagnostic tool for KFD. However, the efficacy of US-CNB is not well evaluated. This study aimed to evaluate the efficacy of US-CNB and compare it with that of US-FNAC in the diagnosis of KFD.Study Design: Retrospective cohort study.Methods: We analyzed 170 patients who were diagnosed with KFD between January 2009 and May 2019. US-FNAC, US-CNB, and excisional biopsy were performed in 47, 114, and 9 patients, respectively. Diagnostic accuracies of US-FNAC and US-CNB were analyzed and compared.Results: Of the 170 patients, 45 and 125 were men and women, respectively. The mean age was 26.9 ± 9.1 years. The most common symptom was cervical lymphadenopathy, followed by fever, headache, and myalgia. The diagnosis of KFD was established primarily by US-FNAC in 21 (44.7%) of the 47 patients, by US-CNB in 109 (95.6%) of the 114 patients, and by excisional biopsy in all 9 patients. There was no specific major complication related to US-FNAC and US-CNB.Conclusion: US-CNB can be considered safe and effective and used as the primary modality for the pathological diagnosis of KFD.Level Of Evidence: 4.
