A Comparative Study of Aspiration Vs Non Aspiration Technique in Fine Needle Cytology of Thyroid Lesion
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 5
Abstract
Background: Fine‑needle aspiration (FNA) of thyroid gland is a widely accepted, simple, safe and accurate method for evaluation of thyroid lesion. Fine needle non-aspiration/ Fine needle capillary cytology (FNNAC/FNC) is an alternative technique not commonly used, though it is easy to perform. Aim- To evaluate the efficacy of fine-needle non-aspiration cytology (FNNAC) with that of fine-needle aspiration cytology (FNAC) of thyroid lesions as regards to cellular and hemorrhagic yield and to compare these two cytological techniques. Methods: The present study includes 129 thyroid cases carried out in the Department of pathology, Rajendra Institute of medical sciences, Ranchi during the one year period from November 2013 to October 2014. The smears were scored using three objective parameters i.e. background blood or clot, amount of cellular material and retention of appropriate architecture in a single blind setting by a cyto-pathologist. The results were analyzed using Student t- testfor independent sample as well as paired data. Results: After evaluation of FNAC and FNNAC on the basis of these scores, FNAC yielded more cellular material than FNNAC (p < 0.001). In a similar manner FNAC has higher average score for background blood (p < 0.001) than FNNAC. However there was no statistical difference in average architecture score.Diagnostically superior samples were more by FNAC; FNNAC yielded more diagnostically adequate smears. Conclusions: After evaluation of both techniques on the basis of these scores, larger numbers of diagnostically superior samples were obtained by FNNAC; however, by FNAC greater numbers of diagnostically adequate smears were observed.
