P. Gattuso et al., Role of fine-needle aspiration in the clinical management of solid organ transplant recipients - A review, CANC CYTOP, 87(5), 1999, pp. 286-294
BAGKGROUND. We evaluated the clinical course of the solid-organ transplant
population at our institutions to determine the role of fine-needle aspirat
ion [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 h
eart, 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 mos
t common malignancies aspirated were malignant solid tumors (15 cases)-incl
uding 8 epithelial malignancies, 5 hepatocellular carcinomas, and 2 mesench
ymal 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 thyro
id, 2 soft tissue, 2 lung, and 2 vertebral body). Surgical and/or autopsy m
aterial was available in 34 cases (55%). There was agreement between the ti
ssue diagnosis and FNA material in 33 cases (97%). One case (3%) was a fals
e 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 pati
ents. Histologic correlation was available in 54% of the cases with an over
all specificity of 100% and a sensitivity of 97%. We conclude that FNA is a
highly sensitive and specific technique in the evaluation of lesions occur
ring in posttransplant patients. Cancer (Cancer Cytopathol) 1999;87:286-94,
