Background: Classical teaching dictates that follicular adenoma (FA) can be distinguished from follicular carcinoma (FC) based on histologic features only. We retrospectively reviewed our institution’s 10-year experience in the use of fine-needle aspiration (FNA) to diagnose follicular thyroid neoplasms. Methods: Patients who had FNA of a thyroid neoplasm from 2000 to 2010 were reviewed. Diagno...

BACKGROUND Fine needle aspiration (FNA) is the standard of care for the diagnostic work-up of thyroid nodules but despite its proven utility, the non-diagnostic rate for thyroid FNA ranges from 6-36%. A non-diagnostic FNA is problematic for the clinician and patient because it can result in repeated procedures, multiple physician visits, and a delay in definitive treatment. Surgeon-performed FN...

INTRODUCTION CT scan-guided fine-needle aspiration (FNA) of lung nodules is a well-established diagnostic technique. In our institution, both FNA and tissue core biopsy (using a 20-gauge needle) under CT scan guidance are routinely performed during the same procedure, and a preliminary diagnosis (an immediate assessment) is rendered. We compared core roll preparations (CRPs) with aspirate smear...

Thyroid Fine Needle Aspiration (FNA) is a safe, effective means of assessment of thyroid cancer 1 with ultrasound guided FNA (UG-FNA) providing a more accurate and cost effective means of diagnosis of thyroid cancer than palpation guided FNA 2 . This report looked at the institutional experience of UG-FNA of the thyroid which were carried out over a 9 year period in the Adelaide, Meath and Nati...

PURPOSE The diagnosis and staging of lung cancer critically depends on surgical procedures. Endoscopic ultrasound (EUS) -guided fine-needle aspiration (FNA) is an accurate, safe, and minimally invasive technique for the analysis of mediastinal lymph nodes (LNs) and can additionally detect tumor invasion (T4) in patients with centrally located tumors. The goal of this study was to assess to what...

BACKGROUND Among patients with papillary thyroid carcinoma (PTC), 30%-80% have cervical lymph node (LN) metastases, which are most commonly located in the central compartment. However, preoperative ultrasonography identifies malignant central compartment LNs in only 20%-30% of cases. We aimed to evaluate the diagnostic value of intraoperative thyroglobulin (Tg) measurement in fine-needle aspira...

PURPOSE This study was performed to determine the malignancy risk of thyroid nodules with isolated macrocalcification and to evaluate the diagnostic efficacy of fine-needle aspiration (FNA) and core needle biopsy (CNB). METHODS From May 2008 to December 2014, a total of 44 patients with isolated macrocalcifications were enrolled from 4,081 consecutive patients who underwent FNA or CNB at a si...

Introduction. Thorough quality control (QC) study with systemic monitoring and evaluation is crucial to optimizing the effectiveness of EUS-FNA. Methods. Retrospective analysis was composed of investigating consecutive patient files that underwent EUS-FNA. QC specifically focused on diagnostic accuracy, impacts on preexisting diagnoses, and case management. Results. 268 patient files were evalu...
