PURPOSE to determine the accuracy of fine-needle aspiration biopsy (FNAB) and of core-needle biopsy (CNB) in diagnosing breast lumps and breast cancer. METHODS this was a cross-sectional, retrospective and descriptive study based on the review of medical records. FNAB and CNB were carried out sequentially according to the routine of the Mastology Service. Both percutaneous procedures were app...

Objective: Measurement of thyroglobulin (Tg) in the wash-out of the needle used to perform FNAB on cervical lymph nodes (FNAB-Tg) provides evidence for metastatic of differentiated thyroid carcinoma (DTC). However, the cutoff value from preoperative patients is still controversial. The objectives of the study were to (1) determine an optimized cutoff value for FNAB-Tg levels (2) compare fine ne...

The objective was to analyze the results of UG-FNAB, performed in unselected consecutive patients with thyroid nodules. Methods. The UG-FNAB records were analyzed in this retrospective study. Indication for biopsy was the presence of at least one nodule detected by ultrasound. Results. 330 patients at mean age ± SD 48.4 ± 11.2 years; women/men = 12.8/1 were analyzed. From the total 596 nodules ...

INTRODUCTION Fine-needle aspiration biopsy (FNAB) as a means of evaluation of palpable soft tissue lesions is poorly utilized in our environment despite the fact that it safe, cheap, quick and easy to perform. METHODS All cases of cases of palpable soft tissue lesions of the trunk and extremities where FNAB was used as the initial evaluation tool were reviewed. Furthermore, the records for co...

OBJECTIVE To study the accuracy of fine needle aspiration biopsy (FNAB) processed by smear cytology and cell block (CB) techniques for the diagnosis of lacrimal gland tumors (LGTs). STUDY DESIGN In a prospective study, we enrolled 48 consecutive patients with LGTs. Immediately after excision of LGTs, the tissues were underwent FNAB with 23-gauge needles. The FNAB samples were processed to pro...

BACKGROUND Patients with pathological tissue mass in thoracic cage found with imaging require histopathological or cytological confirmation of malignancy before treatment. The tissue material essential for patomorphological evaluation can be acquired with fine-needle aspiration biopsies (FNAB) controlled with CT and core-needle biopsy (CNB) under real-time CT fluoroscopy guidance. The purpose o...

BACKGROUND Fine-needle aspiration biopsy has been well established as a diagnostic technique for selecting patients with thyroid nodules for surgical treatment, thereby reducing the number of unnecessary surgical procedures in cases of non-malignant tumors. OBJECTIVES To evaluate the sensitivity, specificity, accuracy, and positive and negative predictive values of FNAB in cases of a solitary...

CONTEXT Detection of thyroid cancer among benign nodules on fine-needle aspiration biopsies (FNAB), which presently relies on cytological examination, is expected to be improved by new diagnostic tests set up from genomic data. OBJECTIVE The aim of the study was to use a set of genes discriminating benign from malignant tumors, on the basis of their expression levels, to build tumor classifie...

BACKGROUND Fine-needle aspiration biopsy (FNAB) is a recognized technique for the basic, preoperative cytological diagnosis of thyroid nodules. AIM OF THE STUDY To analyze the accuracy of FNAB in the diagnosis of thyroid cancer in patients with solitary and multiple thyroid nodules and to compare the demographic, clinical and pathological characteristics of patients with thyroid carcinoma in ...

The present study compared the diagnostic yield of ultrasound-assisted cutting-needle biopsy (CNB) and fine-needle aspiration biopsy (FNAB) in chest lesions. A physician performed ultrasound and FNAB with a 22-G spinal needle in all patients, directly followed by a 14-G CNB in patients without contraindication. A total of 155 consecutive lesions arising from the lung (74%), pleura (12%), medias...
