Resumo
Purpose: to analyze the factors that may be related to
insufficient material in fine needle aspiration cytology
(FNAC).
Patients and Methods: a total of 351 FNAC of patients with
solid breast tumors were studied in a random way: 180 (51%)
by Cameco’s pistol holder and 171 (49%) by the auto-vacuum
device. All smears were analyzed by only one cytopathologist,
and they were described as malignant, suspicious, benign or
insufficient for diagnosis. The significance of each variable
was tested by the χ 2 test.
Results: among the 351 cases analyzed, we found 67 (19%)
of insufficient material. The device used (pistol or auto-
vacuum), the size of the tumor and the clinical stage of the
lesions were not related to the frequency of sufficient and
insufficient material. The age of the patient and the
histological type of the tumor were related to the rate of
insufficient material. Patients younger than 50 had a 12%
rate of insufficient material, compared to 30 above 50
(p<0.03). The patients with fibroadenosis had a rate of 30%,
those with ductal carcinoma, 20%, and those with
fibroadenoma 12% (p<0.02). Conclusion: the present study showed a relatively high rate
of insufficient material (19%), which was influenced by the
age of the patient and the histological type of the biopsied
breast lesion.
