Repeat FNA for thyroid cancer: is the 3-month waiting period needed?

Delaying repeat thyroid fine-needle aspiration (FNA) for 3 mo after a non diagnostic result is not associated with improved diagnostic yield for thyroid cancer.
Patients who received early (3 mo) repeat FNA had similar satisfactory diagnosis yield (84.4% vs 90.9%; P=.117).
Early and late repeat FNA were associated with similar specificity (100% for both) and sensitivity (44.44% vs 51.85%; P=.7631).
Repeat FNA was non diagnostic in 11.04% of patients.
17.6% of patients who had a non diagnostic result on repeat biopsy were found to have malignancy after diagnostic lobectomy.
