Con el objetivo de demostrar mediante de pruebas estadísticas la importancia de la citología exfoliativa en el diagnóstico precoz de lesiones oncológicas bucales, se realizó un estudio observacional analítico transversal en el Hospital Provincial Docente "Manuel Ascunce Domenech" de Camagüey, de enero a diciembre del 2000. Se realizo examen de PDCB a 248 pacientes remitidos, se seleccionaron 41 por presentar lesiones que por su aspecto parecían malignas o sospechosas; todas fueron sometidas a examen citológico y biopsia. Dadas las características del estudio constituyeron a la vez la muestra y el control en dependencia del proceder aplicado. La efectividad de los métodos se comprobó mediante el sistema estadístico de Galen y Gambino. Los resultados citológicos fueron positivos en 30 pacientes, 6 negativos, cero sospechosos y 5 no útiles; en cuanto a las biopsias: 29 carcinomas epidermoides, 10 leucoplasias y 2 descriptivas. Al ser comparadas, la citología demostró poseer 100 % de sensibilidad, 28 % de especificidad, valor predictivo y negativo de 91 % y 100 %, respectivamente, con el 96 % de eficiencia global de la prueba. Se demuestra su importancia como método diagnóstico no invasivo.With the objective of statistically proving the importance of exfoliative citology in the early diagnosis of oral oncological lesions, a crosswise, analytical and observational study was carried out at "Manuel Ascunce" Provincial Teaching Hospital in Camaguey from January to December, 2000. PDCB test was performed on 248 referred patients of whom 41 were selected because they presented with lesions that seemed to be malignant or suspected of malignancy. All these lesions were applied cytological tests and biopsies. Given the characteristics of the study, they were as samples or controls depending on the applied procedures. The effectiveness of the methods is confirmed by Galen and Gambino's statistical system. Cytological results were positive in 30 patients, negative in 6, 0 suspected and 5 were useless. Biopsies showed 29 epidermoid carcinomas, 10 leukoplasias and 2 descriptive. When compared, cytology showed 100% sensitivity, 28% specificity, predictive and negative value of 81% and 100% and the global efficiency of the test was 96%. This paper proved the importance of exfoliative cytology as non-invasive diagnostic method.
