OBJECTIVE: To suggest which system of cytologic classification (Bethesda System or World Health Organization [WHO]) of cervical lesions is more adequate for the Public Health Service of São Paulo State, Brazil, based on morphometric study with the Jandel Videoanalysis (JAVA) System. STUDY DESIGN: The study comprised groups of typical smears: cervical intraepithelial neoplasia (CIN 1) separated into two subgroups: cytopathic effects of human papillomavirus associated or not with dyskaryosis, CIN 2 and CIN 3. The JAVA system of image analysis was used to determine the nuclear/cytoplasmic (N/C) ratio in abnormal cells from each group. RESULTS: Significant differences were detected between the three grades of CIN and between the two subgroups of CIN 1. CONCLUSION: Although image analysis is not applicable to large-scale population screening of cervical smears, its use in the present study favored the three-grade cytologic classification (WHO). In addition, the three-grade classification offers the clinician more options for treatment. Considering the clinical-laboratory characteristics of our public health service, the three-grade classification is more adequate.
