To evaluate the efficacy of the Cytobrush method in aged patients, a comparative study between the Cytobrush smears and cotton swab smears from the uterine cervix was performed. Consecutive 319 cotton swab smears of the endocervix were attempted on aged patients (60‐98 yr, average 77.5 yr) from 1987 to 1988 (A group). Subsequently 391 endocervical smears were attempted by the Cytobrush on aged patients (60‐100 yr, average 76.9 yr) from 1988 to 1990 (B group). The Cytobrush method was more effective in the following two points: (1) The rate of insert‐impossible case in B group (7.2%) was lower than A group (12.5%). (2) The rate of case containing endocervical columnar cells increased in B group (64.7%) compared with A group (47.7%). In contrast, benign epithelial fragments (BFs) were observed in 6.8% of A, in 28.4% of B group. In smears positive for squamous cancer, malignant epithelial fragments (MFs) were noted in 24.5% of A, and 55.1% of B group. Consequently, the differential diagnosis of MFs from BFs is of more importance on the Cytobrush smears of aged patients. © 1994 Wiley‐Liss, Inc.
