Role of fine-needle aspiration in the clinical management of solid organ transplant recipients: a review.
BACKGROUND
We evaluated the clinical course of the solid-organ transplant population at our institutions to determine the role of fine-needle aspiration (FNA) in the clinical management of this subgroup of patients.


METHODS
1196 allograft recipients (522 liver, 288 cardiac, 250 renal, 131 lung, 5 heart and lung) were reviewed. A total of 62 (5.2%) (32 liver, 23 heart, 6 lung, and 1 renal) transplant patients underwent an FNA procedure. Thirty-seven males and 25 females were included, ranging in age from 18 to 71 years (mean 50 years).


RESULTS
Of the 62 fine-needle aspirates, 29 (47%) were neoplastic. The most common malignancies aspirated were malignant solid tumors (15 cases)-including 8 epithelial malignancies, 5 hepatocellular carcinomas, and 2 mesenchymal neoplasms-followed by posttransplant lymphoproliferative disorders (14 cases). Thirteen (21%) aspirates were inflammatory. The remaining 20 (32%) cases were benign aspirates from various sites (9 liver, 3 breast, 2 thyroid, 2 soft tissue, 2 lung, and 2 vertebral body). Surgical and/or autopsy material was available in 34 cases (55%). There was agreement between the tissue diagnosis and FNA material in 33 cases (97%). One case (3%) was a false negative. No false-positive cases were recorded.


CONCLUSIONS
This study showed that over 50% of the aspirates were benign, justifying a conservative approach in the clinical management of these patients. Histologic correlation was available in 54% of the cases with an overall specificity of 100% and a sensitivity of 97%. We conclude that FNA is a highly sensitive and specific technique in the evaluation of lesions occurring in posttransplant patients. Cancer (Cancer Cytopathol)
