title: Comparison of smears and cell blocks in the fine needle aspiration diagnosis of recurrent gynecologic malignancies.
abstract: A retrospective, seven-year study was conducted to evaluate the value of cell blocks as an adjunct to smears in the fine needle aspiration (FNA) diagnosis of recurrent gynecologic malignancies. Eighty-four FNAs were performed on patients with previously diagnosed malignancies of the cervix (39 cases), ovary (27), uterus (14), vulva (2) and vagina (2). Material for the preparation of cell blocks was available in all cases. Smears and cell blocks were reviewed separately, and the findings were categorized as positive, negative, suspicious or unsatisfactory. Identical smear and cell block results were reported in 71 (84.5%) of the 84 cases (45 positive, 20 negative, 1 suspicious and 5 unsatisfactory). In 12 cases (14.3%) the smear was superior to the cell block in detecting malignant cells; while all 12 smears were positive, 8 cell blocks were negative, and 4 were suspicious. In no case was the cell block positive with a negative smear; in one (1.2%) the cell block was positive and the smear suspicious. The results of this study indicate that the additional study of cell blocks is of little benefit in the FNA cytodiagnosis of recurrent disease in patients with documented gynecologic malignancies.
