چکیده
Background: Numerous studies indicate that Papanicolaou smears contain better cellular material when the technique for collecting the sample employs the Zelsmyn Cytobrush TIl. Few studies, however, have examined its ability to increase the percentage of abnormal Papanicolaou smear results in actual clinical practice. Methods: This study looked at 7999 Papanicolaou smears done by 46 primary care physicians to determine the percentage of abnormal results during two different periods. The Cytobrush TIl technique was then implemented; and after 6029 Papanicolaou smears, the percentage of smears with abnormal findings was recalculated. Results: The proportion of Papanicolaou smears demonstra1ing significantly abnormal cells remained constant during the three observation periods: 1.81 percent during the first period, 1.96 percent during the second period (before the Cytobrush TIl technique was implemented), and 1.96 percent during the third period (after the Cytobrush TIl technique was implemented). Conclusions: It seems logical that Papanicolaou smears containing better cellular material from the squamocolumnar Junction would increase the yield of Papanicolaou smears with cancerous and precancerous cells. Our study, however, did not confirm this supposition. While evaluation of Papanicolaou smear technique based on quantity and quality of cellular material is important, we believe the effectiveness of any technique must be evaluated from another perspective the actual practice setting.

For more than 40 years, the Papanicolaou smear has been used to screen for cervical cancer.1,2 The extensive literature on cervical cancer discusses various aspects of the Papanicolaou smear as a screening tool and can be broken down into four
