background and objectives:breast cancer is the most common cancer among women worldwide. fine needle aspiration biopsy (fnab) is one of the methods of breast biopsy which is fast, easy and cost effective. the aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided fnab and guided core needle biopsy (cnb) in the evaluation of breast le...

BACKGROUND We wished to analyse patterns of use of needle biopsy procedures by BreastScreen Australia (BSA) accredited programs to identify areas for improvement. DESIGN BSA services provided anonymous data regarding percutaneous needle biopsy of screen detected lesions assessed between 2005-2009. RESULTS 12 services, from 5 of 7 Australian states and territories provided data for 18212 les...

BACKGROUND The primary aim of this study was to evaluate the diagnostic accuracy of ultrasound (US) in the study of superficial lymph nodes during the follow-up of patients surgically treated for skin tumours. The secondary objective was to compare positive cytological results with histological reports. PATIENTS AND METHODS From 2004 to 2011, 480 patients (male/female: 285/195; median age 57 ...

OBJECTIVE The aim of this study was to evaluate the accuracy of the measurement of thyroglobulin in washout needle aspiration biopsy (FNAB-Tg) to detect papillary thyroid cancer (PTC) metastases. SUBJECTS AND METHODS Forty-three patients (51.4 ± 14.6 years) with PTC diagnosis and evidence of enlarged cervical lymph nodes (LN) were included. An ultrasound-guided fine-needle aspiration of suspi...

OBJECTIVE To assess the role of fine-needle aspiration biopsy (FNAB) in the management of pediatric thyroid nodules. METHODS Results of 30 FNABs performed in our clinic were retrospectively reviewed. Clinical and surgical follow-up data were obtained from the patient files, and clinical correlation and accuracy of FNAB were evaluated. RESULTS The results of 30 FNABs were reported as benign ...

BACKGROUND The objective of this study was to evaluate the validity of fine needle aspiration biopsy (FNAB) according to ultrasonography (US) characteristics in thyroid nodules 4 cm and larger. METHODS We retrospectively reviewed the cases of 263 patients who underwent thyroid surgery for thyroid nodules larger than 4 cm between January 2001 and December 2010. RESULTS The sensitivity of US-...

PURPOSE We performed this study to detect preoperative axillary metastases with ultrasound (US)-guided fine needle aspiration biopsy (FNAB), to eliminate the need for time-consuming and costly sentinel lymph node (SLN) scintigraphy and biopsy steps in the treatment of breast cancer patients, and in that of with suspicious US findings, and to evaluate the accuracy of preoperative US-guided FNAB ...

INTRODUCTION Fine needle aspiration biopsy (FNAB) is the main examination in diagnostics of thyroid nodules. Yet, it does not allow the differentiation of follicular lesions (FL). A new classification of thyroid biopsy results (newC) might improve pre-operative diagnostics mainly due to the introduction of a new subcategory of 'follicular lesion of undetermined significance', as well as the cla...

BACKGROUND Fine-needle aspiration cytology is frequently used for differential diagnosis of neck masses of unknown origin. Inconclusive and even false-negative results are not uncommon. AIM To evaluate the utility of thyroglobulin (Tg) measurement in fine-needle aspirates (FNA-Tg) for detecting cervical lymph node (CLNs) metastases from differentiated thyroid carcinomas. METHODS An ultrasou...

We conducted a retrospective study of 104 cases of salivary gland tumors that were initially assessed by fine-needle aspiration biopsy (FNAB). Based on subsequent histopathologic analysis of excised specimens, we found that preoperative FNAB was highly sensitive and specific for both benign and malignant tumors-including the most common, pleomorphic adenomas and squamous cell carcinomas, respec...
