Background: The recommended management of Atypia/follicular lesion of unknown significance (AUS/FLUS) includes active surveillance (AS), repeated fine needle aspiration (RFNA), diagnostic surgery or genetic testing
Purpose: To assess the management of AUS/FLUS patients in without implementing genetic testing.
Methods: A single institute cohort study of all adult patients who underwent ultrasound-guided FNA (USGFNA) between January 2009 and January 2013 and were followed until January 2016.
Results: The median follow-up time was 4.6 years (range 3.2-6.8). Forty-eight patients (57%) were referred to AS, and 36 patients (43%) were referred for diagnostic surgery. Thirty-six of the AS group (75%) underwent RFNA. An additional eight patients from the AS group subsequently underwent diagnostic surgery. Malignancies rate in the diagnostic surgical samples was 34% (15/44). 61.1% of RFNAs resulted in benign cytology. Analysis of adherence to follow-up in the 36 AS patients showed an adherence rate of only 53%. Men demonstrated better compliance (31.6% vs. 5.8%, respectively, p=0.052), especially males in their 6th decade of life.
Discussion: Quality patient selection for surgery based on clinical, sonographic and cytological considerations is feasible, reaching malignancy rate of 34%. RFNA was shown to be a reliable and important tool in the management of these patients, yet active surveillance should be offered after careful assessment of the patient and the nodule’s characteristics
Conclusion: When Genetic tests these tests are not feasible, careful management of AUS/FLUS patients may still offer good results. Compliance to follow-up schedules should be a major consideration when selecting patients for AS.
