La introducción de programas de cribado y el tratamiento de células precancerosas ha reducido la incidencia del cáncer de cérvix. El equipo de Kyrgiou ha revisado los datos de 27 estudios y ha llegado a la conclusión de que la conización con crioterapia eleva el riesgo relativo de parto pretérmino, bajo peso al nacer y cesárea. La excisión quirúrgica de las lesiones premalignas eleva el riesgo relativo de nacimientos pretérmino, de bajo peso y de rotura prematura de membranas, mientras que la conización con láser ofrece los mismos resultados que las anteriores.
Para los autores del trabajo, las intervenciones para extirpar las lesiones precancerosas en el cuello del útero están acompañadas de morbilidad asociada a la gestación, por lo que se debería informar a las pacientes sobre los riesgos que pueden aparecer.
