Validity of fine needle aspiration cytology in diagnosing thyroid gland neoplasms

Abstract: Objectives: To determine the validity of Fine needle aspiration cytology (FNAC) in diagnosing thyroid neoplasms and to identify the causes of false positive and negative results. Method:Thyroid FNACs of 100 patients with subsequent histology were analysed. The diagnostic categories used included Thy 1 to Thy 5. Thy 3 was subdivided into Thy 3a and Thy 3b depending on the presence or absence of features suggestive of a follicular neoplasm. Histology results were categorized as neoplastic or non neoplastic.

“…Therefore our findings (31-40 years age group) are within the findings of the international studies (Table 4). There is a wide variation in the global statistics relating to validity of FNAC as a tool for diagnosing thyroid pathology and the Royal College of pathologists (RCPAAustralasia) has allowed a wide range for sensitivity, specificity of FNAC with regard to thyroid neoplasms [13,14]. The sensitivity, specificity and accuracy for diagnosis of neoplasm by FNAC in our study are acceptable.…”

“…It is important to differentiate neoplastic from non neoplastic thyroid enlargement, to provide optimum healthcare to affected patients. Thyroid fine needle aspiration cytology (T-FNAC) is a widely accepted diagnostic tool for preoperative assessment of solitary thyroid nodules, diffuse and multi-nodular goiters with specificity ranging between 67%-100% and sensitivity ranging between 77.7%-93% (4)(5)(6)(7)(8). T-FNAC diagnostic value is enhanced when combined with radiological investigations and thyroid function assays (6).…”
