Abstract

Objective: To compare the diagnostic rate of ultrasound-guided fine-needle aspiration biopsy (FNAB) with the diagnostic rate of combined FNAB and core-needle biopsy in the evaluation of nodular thyroid disease. Methods: We performed a retrospective case-control study by reviewing charts of patients who underwent ultrasound-guided FNAB and core-needle biopsy of the thyroid at a tertiary referral center from January 1999 to December 2001. Results were classified as diagnostic (negative, suspicious, or positive for malignancy) or nondiagnostic. These findings were compared with an age- and sex-matched control group who underwent only FNAB. Complications between the groups were reviewed. Results: The patient group consisted of 320 patients who underwent 340 ultrasound-guided fine-needle aspiration and core-needle biopsies of the thyroid; the control group consisted of 311 patients who underwent 340 FNABs. There was no significant difference in the nondiagnostic rates between groups-12.9% in patients who had FNAB-only compared with 10.9% in patients who had both procedures (proportion difference, -2.1%; 95% confidence interval, -7.0% to 2.9%; P = .41). There was a trend towards an increased incidence of hematoma and infection in the core biopsy group. In the group that underwent FNAB and core-needle biopsies, 10 patients (3.1%) developed biopsy-specific complications (hematomas in 8 patients, biopsy site infections in 2 patients). In the FNAB-only group, 3 patients (1.0%) developed hematomas; there was no incidence of infection. Conclusions: In the evaluation of thyroid nodules, the addition of core-needle biopsies to FNAB confers little benefit in decreasing the nondiagnostic rates and may be associated with increased complications. Core-needle biopsies should not be routinely performed in the evaluation of thyroid nodules, but rather, patient selection for the more invasive core biopsy should be done judiciously.
