abstract introduction:   it is more than 60 years that fine needle aspiration (fna) has been used for diagnosing palpable breast masses and has been known as an effective method for several years in europe. in this study, we compared the diagnostic accuracy of fna with open biopsy in tabriz and shiraz, iran. material and methods: we studied 100 patients with breast lesions in tabriz imam khomei...

Background and Objectives: We aimed at evaluating the efficacy of fine needle aspiration biopsy (FNA) in comparison with histopathology and demonstrating whether cytological study could be a proper diagnostic tool in orbital mass lesions. Materials and Methods: In a cross sectional study during 36 months, patients referred to our ophthalmologic center affiliated to Tehran University of Medical...

BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was initially introduced for diagnosing gastrointestinal and pancreatic lesions, and later on for lung and mediastinal lesions. It can provide tissue diagnosis of lung cancer where bronchoscopy is non-diagnostic. It is a minimally invasive method for lymph node (N) and metastasis (M) staging of non-small cell lung cancer, ...

Background: Breast cancer is the most common in world, as well Cameroon, where it represents about 20.1% of all cancers recorded 2020. The number pathologists country few seven for a population 26 million. diagnostic performances modalities other than histology—clinical breast examination (CBE), imaging and fine needle aspiration cytology (FNA)—in our context are not known. Study Objectives: Ou...

BACKGROUND Differential diagnosis of pancreatic solid masses with EUS-guided FNA (EUS-FNA) is still challenging in about 15% of cases. Mutation of the K-ras gene is present in over 75% of pancreatic adenocarcinomas (PADC). OBJECTIVE To assess the accuracy of K-ras gene mutation analysis for diagnosing PADC. DESIGN We systematically searched the electronic databases for relevant studies publ...

Patients with solitary thyroid nodules should have fine-needle aspiration (FNA) cytology as the initial screening test, but the most of those referred to a surgeon usually undergo frozen section examination (FS). The aim of this retrospective study was to assess the usefulness of FNA cytology and FS together in patients with a solitary thyroid nodule (TN). Two-hundred and ten patients with a TN...

BACKGROUND Endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) of pancreatic lesions is being increasingly used. Our aim was to determine the safety, accuracy, and clinical utility of EUS-guided FNA in both the diagnosis and staging of pancreatic cancer. METHODS Forty-four patients (24 men/20 women) had EUS-guided FNA of pancreatic lesions (39 head/neck, 5 body, 3 tail) and/or ass...

OBJECTIVE To determine the impact of endoesophageal ultrasound-guided fine-needle aspiration (EUS-FNA) on management of thoracic malignancies. METHODS One hundred and twenty patients referred for invasive diagnostic and resection of thoracic malignancies were studied prospectively. Negative and inconclusive EUS-FNA findings were assessed by video-assisted mediastinoscopic lymphadenectomy (VAM...
