The purpose of this study was to assess the usefulness of HER2 levels in ultrasonographically guided fine-needle aspiration biopsy (US-FNA) aspirates of axillary lymph nodes (ALNs) in the determination of lymph node metastasis or the characterization of primary breast cancer, and to correlate the HER2 levels in US-FNA aspirates (FNA-HER2s) of metastatic ALNs with the HER2 statuses of correspond...

BACKGROUND AND OBJECTIVE Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). P...

Background and study aims  The low sensitivity of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), especially for the diagnosis of serous cystadenomas (SCAs), can be associated with diagnostic uncertainty that can regularly lead to unnecessary surgical procedures. Needle-based confocal laser endomicroscopy (nCLE) used with EUS-FNA improves diagnostic accuracy, helping to reduce un...

Introduction of endoscopic ultrasound (EUS) to medical practice has brought a huge change in diagnostic algorithm of many gastrointestinal diseases. Addition of EUS-guided fine needle aspiration (FNA) upgraded diagnostic power of EUS. In this focused review series, value of EUS-FNA in the diagnosis of various diseases and tips for getting the best results with EUS-FNA are described by four invi...

ارزیابی نسج کبد که از طریق نمونه برداری از این عضو امکانپذیر می شود، اساس ارزیابی و مدیریت بسیاری از بیماری های کبدی می باشد. در حال حاضر با وجود تست های حساس و در دسترس جهت تشخیص بیماری های کبدی، همچنان بیوپسی کبد به عنوان یکی از اساسی ترین ابزار تشخیص دهنده و درمانی بیماری های کبد، به خصوص بیماری های مزمن کبدی محسوب می شود. در واقع بیوپسی کبد همواره به عنوان یک آزمون مکمل آزمون های دیگر به شم...
