Validez de la inspección visual con ácido acético frente a citología cervical

Abstract

Resumen Introducción: las lesiones precancerosas, condiciones asociadas a la exposición al virus del papiloma humano (VPH), amenazan la salud de la mujer en diferentes etapas de la vida, desde la adolescencia a la vejez. Se ha observado que una estrategia de bajo costo, como la inspección visual con ácido acético (IVAA), revela lesiones cervicouterinas, al tiempo que se establecen intervenciones que permiten modificar el curso de la enfermedad, lo cual mejora la calidad de vida de la mujer. Objetivo: determinar la validez de la inspección visual con ácido acético en comparación con la citología cervical para detección de lesiones precancerosas. Material y métodos: estudio descriptivo, observacional, transversal, prospectivo, analítico. El tipo de muestreo fue no probabilístico. La muestra estuvo compuesta por 638 participantes. Los datos se recolectaron con una ficha de recolección de datos y se analizaron de forma cuantitativa con el programa SPSS. El estudio se apegó a lo dispuesto en la Ley General de Salud en Materia de Investigación en México y contó con la aprobación del Comité Local de Investigación del Instituto Mexicano del Seguro Social (IMSS). Resultados: la IVAA comparada con la citología cervical mostró una sensibilidad de 75% y una especificidad de 98%, un valor predictivo positivo de 47%, un valor predictivo negativo de 99%, una probabilidad post-test positivo de 97% y una concordancia de 61%. Conclusión: la IVAA presentó una sensibilidad aceptable y puede ser utilizada como prueba de cribado en conjunto con la citología.

Background: Precancerous lesions, conditions associated with exposure to human papillomavirus (HPV), threaten women's health at different stages of life, from adolescence to old age. It has been observed that a low-cost strategy, such as visual inspection with acetic acid (VIA), reveals cervical lesions, while establishing interventions that allow modifying the course of the disease, thus improving women's quality of life. Objective: To determine the validity of VIA in comparison with cervical cytology for the detection of precancerous lesions. Material and methods: Descriptive, observational, cross-sectional, prospective, analytical study. The type of sampling was non-probabilistic. The sample consisted of 638 participants. Data were collected with a data collection form and analyzed quantitatively with the SPSS software. The study complied with the provisions of the General Health Law on Research in Mexico and was approved by the local research committee of the Mexican Institute for Social Security (IMSS, according to its initials in Spanish). Results: VIA compared with cervical cytology showed a sensitivity of 75%, a specificity of 98%, a positive predictive value of 47%, a negative predictive value of 99%, a positive post-test probability of 97%, and a concordance of 61%. Conclusion: VIA showed an acceptable sensitivity and can be used as a screening test in conjunction with cytology.
