Neoplasias intraepiteliais cervicais: faixa etária no momento do diagnóstico citológico / Cervical intraepithelial neoplasia: age group in the moment of the cytological diagnosis

Objetivo: Avaliar a distribuição de diagnósticos citológicos de neoplasia intraepitelial cervical (NIC), considerando a idade das mulheres incluídas. Material e Métodos: Osresultados citológicos de mulheres com NIC 1 (721), NIC 2(218) e NIC 3 (84) foram analisados em um modelo estratificado por faixa etária. Resultados e Conclusão: As prevalências encontradas foram de 70,48% (721/1023) para NIC 1, 21,31% (218/1023) para NIC 2 e 8,21% (84/1023) para NIC 3. Os diagnósticos citológicos de NIC 1 foram observados com maior frequência em mulheres com menos de 40 anos (88,35%; 637/721). Os diagnósticos citológicos de NIC 2 também foram mais frequentes emmulheres com menos de 40 anos, com uma prevalência de 43,6% (95/218), observada na faixa etária de 20-30 anos, e de 22,5% (49/218) em mulheres de 31-40 anos. Osdiagnósticos de NIC 3 foram mais frequentes em mulheres com mais de 30 anos (83,3%; 70/84). Houve uma maior prevalência de NIC 1 e NIC 2 em mulheres na faixa etária de 20 a 30 anos, enquanto que NIC 3 teve prevalência maior em mulheres com mais de 30 anos. É possível que a história natural da NIC 2 seja mais próxima a de NIC 1, quando comparadaà de NIC 3.

Objective: To evaluate the distribution of the cytological diagnosesof cervical intraepithelial neoplasia (CIN) considering the includedwomen's age group. Material and Methods: The cytological resultsof woman with CIN 1 (721), CIN 2(218) and CIN 3 (84) were analyzedin a stratified model by age group. Results and Conclusion: Thetotal prevalences founded were 70.48% (721/1023) for CIN 1, 21.31%(218/1023) for CIN 2 and 8.21% (84/1023) for CIN 3. The cytologicdiagnosis of CIN 1 were observed more frequently in women underthe age of 40 (88.35% 637/721). The cytologic diagnosis of CIN 2were also more frequent in women under 40 years of age with aprevalence of 43.6% (95/218) observed in the age group of 20-30years and 22.5% (49/218) in women of 31-40 years. The diagnosis ofCIN 3 were more frequent in women over 30 years (83.3% 70/84).There is a higher prevalence of CIN 1 and CIN 2 in women aged 20to 30 years while CIN 3 prevalence is higher in women over 30 years.It is possible that the natural history of CIN 2 is closer to CIN 1 whencompared to CIN 3.

Cytopathic effects of human papillomavirus infection and the severity of cervical intraepithelial neoplasia : A frequency study.

Cytopathic effects related to the human papillomavirus (HPV) infection are more frequently found in cervical intraepithelial neoplasia (CIN) 1; however, there are indications that at least half the histological diagnoses of CIN2 and CIN3 include koilocytosis areas. The objective of this study was to evaluate the frequency of the cytological criteria suggestive of HPV infection in the cervical smears of women with a histological diagnosis of CIN. One hundred and sixty-two women with abnormal cervical smears and a diagnosis of CIN confirmed by histopathology were selected, including 46 cases of CIN 1, 42 of CIN 2 and 74 cases of CIN 3. Koilocytosis was found in 63% of the smears from women with a histopathological diagnosis of CIN 1. This sign was observed in 26.2% and 25.7% of smears of women with a diagnosis of CIN 2 and CIN 3, respectively. Cytomegaly also was frequent in cervical smears of women with histopathological diagnosis of CIN 1 (71.8%). On the other hand, spindle cells and atypical metaplasia were more frequent in women with CIN 2 and CIN 3. Atypical parakeratosis showed similar frequency in all grades of CIN diagnosis. Koilocytois and cytomegaly were inversely correlated with the diagnosis of CIN2 or CIN 3, with OR values respectively of 0.30 (95%CI 0.13-0.68) and 0.26 (95%CI 0.11-0.58). The others signs analyzed did not show any significant association. Koilocitosis and cytomegaly can provides good reassurance that a patient with atypical cervical smear have CIN 1.
