Resumen

Objetivos: Este estudio pretende evaluar la utilidad del test APTIMA, que identifica mRNA E6/E7 de 14 tipos de virus del papiloma humano de alto riesgo (HPV-AR), para el diagnóstico de neoplasias intraepiteliales cervicales (CIN) grado 2 o peor, así como comparar la sensibilidad de dicho test con otros test diagnósticos. Material y métodos: Un total de 203 pacientes, referidas a colposcopia por presentar una citología anómala o un test positivo para HPV-AR, fueron evaluadas con APTIMA, Hybrid Capture (HC2), Cobas 4800, Linear Array y tinción inmunohistoquímica p16INK4a. Resultados: Se calculó la sensibilidad para todos los test teniendo como endpoint CIN2+ y CIN3+, encontrando cifras de sensibilidad superiores al 90% para todos ellos. La sensibilidad para APTIMA fue 92.80% y 92.94% para CIN2+ y CIN3+ respectivamente (p<0.0001), la de HC2 96.80% y 95.29% (p<0.0001), la de Cobas 4800 96.00% y 95.29% (p=0.011), la de Linear Array 98.40% y 97.65% (p=0.007) y la de p16INK4a 95.90% y 96.39% (p<0.0001). El test APTIMA y la tinción imnunohistoquímica p16INK4a presentaron los mejores valores de especificidad, 35.90% y 47.94%, respectivamente (p<0.0001). Conclusión: APTIMA tiene una sensibilidad similar a otros test diagnósticos para la detección de CIN2+, por lo que podría ser un test útil para el screening del cáncer de cérvix.
