BACKGROUND Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) with bedside cytopathology is the gold standard for assessment of pancreatic, subepithelial, and other lesions in close proximity to the gastrointestinal tract, but it is time-consuming, has certain diagnostic limitations, and bedside cytopathology is not widely available. AIMS The goal of this study is to compare the ...
The aim of this retrospective study is to evaluate the diagnostic yields of combining fine needle aspiration (FNA) with brushing cytology (BC) in clinical work-up of pancreatic ductal adenocarcinoma. The study included a total of 97 patients who underwent both FNA and BC along with histologic/clinical follow-up (F/U). Cytologic diagnoses were categorized as negative for neoplasm (NEG), atypical...
AIMS To evaluate the correlation of fine needle aspiration (FNA) cytology and frozen section biopsy in the diagnosis of thyroid nodules. METHODS The medical records of 662 patients who underwent FNA cytology of the thyroid and thyroid surgery were analysed. Frozen section biopsies were taken from 586 of the 662 patients. The diagnostic correlations of FNA cytology, frozen section, and both FN...
BACKGROUND/AIMS Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported the usefulness of EUS-FNA/B for rectal and perirectal lesions. This study reports our expanded experience with EUS-FNA/B for rectal and perirectal lesions in term...
The National Cancer Institute (NCI) sponsored the NCI Thyroid Fine-Needle Aspiration (FNA) State of the Science Conference on October 22-23, 2007 in Bethesda, MD. The 2-day meeting was accompanied by a permanent informational website and several on-line discussions between May 1 and December 15, 2007 (http://thyroidfna.cancer.gov). This document summarizes the indications for performing an FNA ...

RATIONALE Assessment of mediastinal lymph nodes is recommended in patients with non-small cell lung cancer without distant metastases. Linear transesophageal endoscopic ultrasound with real-time guided fine-needle aspiration (EUS-FNA) is a promising, nonsurgical tool for mediastinal staging. OBJECTIVES We conducted a randomized controlled trial comparing surgical staging with EUS-FNA. METHO...
Ultrasound-guided fine-needle aspiration (FNA) cytology is the most widely used screening and diagnostic method for thyroid nodules. Although Western guidelines for managing thyroid nodules and the Bethesda System for Reporting Thyroid Cytopathology are widely available throughout Asia, the clinical practices in Asia vary from those of Western countries. Accordingly, the Working Group of Asian ...
The Flora of North America (FNA) is a large-scale collaboration involving over eight hundred scientists working together to create a 30-volume compendium of all naturally occurring plants in North America. The size and complexity of the project result in significant cognitive overload which comprises not just information or data but also work practices and activities. We view FNA as a distribut...
Fine-needle aspiration (FNA) biopsy of the thyroid gland is an accurate diagnostic test used routinely in the initial evaluation of nodular thyroid disease (1-6). Epidemiologic studies suggest that nodular thyroid disease is a common clinical problem, with a prevalence of 4% to 7% in the adult population in North America and an annual incidence of 0.1%, which translates into approximately 300,0...
