Accuracy of Pathologic Diagnosis in Thyroid Lesions

Arch Otolaryngol Head Neck Surg. 1992;118(9):918-922. doi:10.1001/archotol.1992.01880090034011

• Although there is much literature devoted to the role that fine-needle biopsy plays in the management of the thyroid mass, only a handful of studies deal with the diagnostic accuracy of the frozen section and final paraffin section of thyroid lesions. Fine-needle biopsy results, frozen-section diagnoses, final paraffin-section diagnoses, and panel review diagnoses were recorded for 137 consecutive patients who underwent thyroidectomy procedures. The overall accuracy of fine-needle biopsy, frozen-section, and paraffinsection diagnoses was 81%, 87%, and 94%, respectively. The high positive predictive value and specificity of both the fine-needle and frozen-section modalities suggests that intraoperative pathology consultation, given that the preoperative needle aspirate is positive for malignant neoplasia, can offer little further in the treatment of the patient. Stastistical analysis of the accuracy of the three modalities suggests strategies for accurate treatment of the thyroid nodule.
