Validity of Needle Aspiration Cytology and Frozen Section in Thyroid Tumor

초록

The role of fine needle aspiration cytology(FNAC) and frozen section (FS)in management of thyroid neoplasms continues to generate considerable controversy. We review our recent experiences to determine the clinical utility of FNAC and FS in our surgical menagement and investigated reliability of FNAC and FS in planning the extent of thyroid resection. Material and method: All patients who had operations for thyroid disease from May 1996 to November 2003 were identified in our retrospective database. 212 patients included our study.FNAC was undertaken in 175 patients and FS was done in 148 patients. Result : The sensitivity and specificity of FNAC were 72.1% and 100%, respectively, and those of FS were 67.2% and 100%. The results of FNAC were benign(n=72), malgnancy(n=31), indeterminate(n=9), and nondiagnostic(n=63). The results of FS we benign(n=95), and malignancy(n=31), indeterminate(n=53). The 9 indeterminate cases on FNAC were benign(n=6) and malignancy(n=3) on final pathology, and benign(n=7) and malignancy(n=2) on FS.
