ACURÁCIA DO TESTE DE PAPANICOLAOU NO DIAGNÓSTICO DE LESÕES PRECURSORAS DO CÂNCER CERVICAL

Abstract

Objetivo: Avaliar a acurácia da citologia e colposcopia. Métodos: Foi realizado um estudo retrospectivo entre 184 mulheres consecutivas que foram submetidas à biópsia cervical. Os desfechos (lesões precursores e câncer cervical) assim como os resultados do teste de Papanicolaou e colposcopia, foram dicotomizadas em lesão intraepitelial de baixo grau ou menos e lesão intraepitelial de alto grau ou mais. Foi calculado sensibilidade, especificidade, valor preditivo positivo (VPP) e negativo (VPN) para cada, todos com intervalo de confiança de 95%. Resultados: Foram encontrados 184 pacientes que preencheram os critérios do estudo. A média de idade foi de 30.2 ± 10.6 (variação 15-89). A sensibilidade, especificidade e acurácia foram melhores na colposcopia do que no exame de Papanicolaou: a sensibilidade foi de 70,4% (IC 95% 67,0% - 81,0%) e 54,0% (IC 95% 46,8% - 61,2%) respectivamente, a especificidade foi de 96,3% (95% IC 93,0% -99,0%) e 91,0% (IC 95% 86,9% -95,1%) respectivamente, e a acurácia de 88,9% (IC 95% 75,3% -86,6%) e 80,9% (IC 95% 75,3% -86,6%) na colposcopia e citologia, respectivamente. Conclusão: Os falsos negativos foram um grande problema detectado em nosso estudo, eles não diagnosticaram 46% dos casos de lesão intraepitelial escamosa de alto grau (LIEAG) ou mais pela citologia e 26% pela colposcopia.Palavras-chave: Acurácia; Exame de Papanicolaou; Lesões Precursoras; Colposcopia.
