“…Third, we used relatively small sample size to assess the low incidence of complication of FNA and CNB. Although CNB has been known as a safe procedure [ 42 43 44 ], a further prospective investigation with a larger sample size is necessary to verify the results of our study. Finally, we performed local anesthesia with 2% lidocaine when performing the CNB procedure, but not with FNA procedure.…”

Background:To compare pain, tolerability, and complications associated with fine needle aspiration (FNA) versus core needle biopsy (CNB). Methods: FNAs were performed using 23-gauge needles and CNBs were performed using 18-gauge double-action spring-activated needles in 100 patients for each procedure. Patients were asked to record a pain score using a 10-cm visual analog scale and procedure tolerability. Complications and number of biopsies were recorded. Results: The median pain scores were similar for the FNA and CNB approaches during and 20 minutes after the biopsy procedures (3.7 vs. 3.6, P=0.454; 0.9 vs. 1.1, P=0.296, respectively). The procedure was tolerable in all 100 FNA patients and in 97 CNB patients (P=0.246). The mean number of biopsies was fewer in the CNB group (1.4 vs. 1.2, P=0.002). By subgroup analysis (staff vs. non-staff), no significant difference was detected in any parameter. There were no major complications in either group, but three patients who underwent CNB had minor complications (P=0.246). Conclusion: FNA and CNB show no significant differences for diagnosing thyroid nodules in terms of pain, tolerability, or complications.

“…However, due to its substantial rate of nondiagnostic and indeterminate results, various methods to enhance its diagnostic yield have been suggested [1][2][3][4][5][6][7]. Core-needle biopsy (CNB) has emerged as a diagnostic tool for thyroid nodules based on recent advances in core biopsy devices (spring-activated single-or double-action needles) and the widespread use of highresolution ultrasonography (US) [8,9]. CNB has been reported to be an effective and safe diagnostic tool, as it allows clinicians to obtain a core tissue sample with potential information on architectural histological structures, thus enabling immunochemical staining [10][11][12][13].…”

Ultrasonography 2020;39:159-165 Purpose: The purpose of this study was to present the distribution of lesions among the six categories of the pathology reporting system for thyroid core-needle biopsy (CNB), along with the range of malignancy risk of each category based on different diagnostic criteria for benignity in a clinical cohort. Methods: For 1,216 consecutive nodules (≥1 cm) of 1,125 patients who underwent CNB at two hospitals, the diagnostic results based on the six categories of thyroid CNB were analyzed. Patients were divided into three groups according to prior fine-needle aspiration (FNA) status: second-line CNB for nodules where prior FNA yielded nondiagnostic or unsatisfactory results (n=57), second-line CNB for nodules with prior FNA results of atypia/follicular lesion of undetermined significance (AUS/FLUS) (n=303), and first-line CNB (n=856). Results: The proportion of nodules in each CNB category and the range of the malignancy rate for each category was as follows, in order from category I to VI: 1.8%, 23.1%-75.0%; 57.9%, 0.7%-16.7%; 16.0%, 13.2%-46.7%; 8.8%, 53.8%-56.8%; 2.0%, 100%; and 13.5%, 100%. First-line CNB was associated with a higher rate of conclusive diagnoses (category II, IV, or VI) (725 of 856, 84.7%) than second-line CNB with prior nondiagnostic or AUS/FLUS FNA results (241 of 360, 66.9%; P<0.001). Conclusion: The overall distribution of nodules across the six categories of thyroid CNB and the ranges of malignancy risk for those categories were presented in a clinical cohort. Firstline CNB tended to produce a higher rate of conclusive results than second-line CNB with prior inconclusive FNA results.

“…During the follow-up period, the indications for repeated RFA or EA include the presence of power Doppler signals or enhancing portion on a CT scan, despite a reduction in the size [5,6,9,13]; volume reduction <50% [8]; or the presence of residual cancer tissue on core-needle biopsy or fine-needle aspiration cytology [5,8,10,51,52]. An additional treatment may be required for large cancers.…”

Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid malignancy and has a good prognosis and low mortality rate. Surgery is the standard treatment for patients with primary and recurrent thyroid cancer. Although patients with PTC usually exhibit excellent treatment outcome, the incidence of recurrence in the neck ranges from 20% to 59%. When a patient with thyroid cancer is contraindicated for surgery, ultrasound (US)-guided ablation techniques, including ethanol ablation (EA) and thermal ablations, are suggested alternatives. In this review, we evaluated the indications, devices, techniques, clinical outcomes, and complications associated with US-guided EA and thermal ablations based on available scientific evidence and expert opinions regarding the use of ablation for primary and recurrent thyroid cancers.
