Abstract

Background: Fine needle aspiration (FNA) diagnoses are usually confirmed via surgical pathology or via evaluation of clinical outcomes. However, such confirmation may not occur for patients who die shortly after FNA, and autopsy may be a useful quality assessment tool in these cases. Also, there is little data investigating the relationship between FNA and mortality. We sought to demonstrate the autopsy as a quality assessment tool for the FNA and assess the contribution of FNA to mortality in patients who die soon after the procedure. Methods: A search of our database was performed from 1992 to 2016 for patients who were autopsied after dying within 30 d of an FNA. Concordance between findings from FNA, autopsy, and any intervening surgical pathology material was determined. Finally, a subjective determination of the likelihood that FNAs contributed to deaths was made by reviewing autopsy reports. The contribution was categorised as either “unlikely”, “possible”, or “probable”. Results: Fifty-eight patients (average age = 58 y) met the search criteria. Thirty-six (62%) patients had malignancies. Surgical pathology material was obtained concurrently or following FNA in 20 cases (34%). There was 73% concordance between FNA and autopsy findings, which compares to 80% concordance between FNA and surgical pathology diagnoses. The FNA was determined to be at least possibly contributory to death in 7/58 cases (3 cases designated as “probable,” and 4 as “possible”). Conclusion: Autopsy can be used to validate FNA diagnoses and, like surgical pathology, confirms that FNA diagnoses are mostly accurate. However, in a small number of patients, FNA can precipitate death.
