Abstract Fifty-nine successive cases of fine-needle aspiration (FNA) of the liver were reviewed to determine the efficacy of various rinse and smear preparations in rendering a diagnosis of cancer. Preparations included Papanicolaou- and Diff-Quik-stained smears, Millipore filters, cytocentrifugation, and cell blocks. Of 33 of 59 cases diagnostic for cancer, 90\% were positive on rinse, 78\% on smear, and 69.6\% on both rinse and smear. Seven cases (21.2\%) were diagnostic on rinse preparation only and would otherwise have been interpreted as equivocal. Papanicolaou smears and cell block rinses were most valuable to evaluate malignancy in the liver, using the FNA technic. The authors believe rinse preparations justify their cost for assessment of cancer and are essential to establish the diagnosis in a significant number of cases.
