Fine-needle Aspiration Biopsy for Head and Neck Tumors

Abstract

Fine-needle aspiration biopsy was performed in 109 patients(143 specimens) with head-neck tumors, and its accuracy and usefulness were evaluated. The total histological accuracy rate was 78.3%, 81.0% for benign tumors and 73.6% for malignant tumors.
The overall misdiagnostic rate was 21.7%, the false negative rate was 4.9%, and false positive rate 1.4%, with unsatisfactory material accounting for 15.4%. The histological accuracy rate excluding unsatisfactory cases was 92.6%. The accuracy rate of fine-needle biopsy for histological examination of smears will be improved as the number of unsatisfactory cases is reduced. This method is useful for the diagnosis of head and neck tumors.
