Diagnostic accuracy of fine needle aspiration of thyroid nodule versus biopsy in thyroid lesions.

چکیده
BACKGROUND FNA biopsy of thyroid is a rapid, minimally invasive, and cost effective first line procedure in the evaluation of thyroid nodule. This study was conducted to evaluate the cytological accuracy, sensitivity and specificity of fine needle aspiration (FNA) of solitary thyroid nodules in correlation with post-surgical histological findings. METHODS This retrospective study was carried out at Department of Pathology, Abbottabad International Medical College, Abbottabad from January 2009 to December 2010. A total of 81 patients with clinically palpable solitary thyroid nodule were included in the study. Thyroid function tests were initially performed followed by FNA of thyroid nodules later operated and histopathological examination was conducted on the excised nodules. FNA diagnoses were correlated with the histological findings. The accuracy, sensitivity and specificity of the procedure were determined. RESULTS Out of 81 cases, 5 (6.2%) were unsatisfactory and 76 cases were satisfactory for cytological evaluation. Cyto-histopathological correlation was carried out for these cases. The study showed a diagnostic accuracy of 93% with sensitivity and specificity rates of 75% and 96% respectively. Positive predictive value is 81% and negative predictive value is 95%. CONCLUSION Fine needle aspiration (FNA) has evolved as an accurate and sensitive diagnostic tool for the initial screening of patients with thyroid nodules, and has reduced the need for unnecessary surgery.

Diagnostic Accuracy of Frozen Section in Comparison With Fine Needle Aspiration Cytology in Thyroid Lesions – A Prospective Study
Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

In the assessment of Thyroid lesions Fine needle aspiration cytology (FNAC) is widely considered as the diagnostic technique of choice. Retrospectively 96 patients with Thyroid nodules seen during the period August 2012 – July 2013 were analyzed to determine the utility and diagnostic accuracy in establishing the diagnosis of thyroid lesions.
متن کاملDiagnostic Fine Needle Aspiration in a Case of Riedel’s Thyroiditis
In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...

Background and Objectives: Fine needle aspiration cytology (FNAC) is an established out- patient procedure used in primary diagnosis of palpable thyroid lesions. A modified technique fine needle capillary sampling (FNCS) obviates the need of suction, is less painful, patient friendly and reported to overcome the problem of inadequate and bloody specimens. The aim of our study was to compare the...

Background and Objective: Thyroid nodules are among the most common clinical problems and the application of an inexpensive and accurate diagnostic method prevents performing inessential surgeries. In this regard, the aim of this study was to compare the cytologic report of fine-needle aspiration (FNA) of thyroid nodules with the results of thyroid surgery. Materials and Methods: In this cross...
متن کاملAssessment of the effectiveness of local anesthesia before thyroid fine needle biopsy considering the size of the nodule
Background: Fine needle aspiration biopsy (FNAB) is usually used to distinguish the malignant and benign nodules. Applying a biopsy needle evokes a sense of fear and pain in the patients. Although some studies refute the usefulness of local anesthesia (LA) prior to fine needle aspiration biopsy, it is still debatable. This prospective cross-sectional study intended to evaluate the effect of LA ...
