Presente y Futuro del Tratamiento del CM

 

En los países desarrollados del mundo, donde el acceso al tratamiento del CM está menos obstaculizado por barreras del sistema de salud, la mortalidad por CM ha disminuido progresivamente entre los años noventas del siglo pasado y la actualidad (9,131). En el CM metastásico con RH positivos, específicamente, la supervivencia prácticamente se ha duplicado, pasando de 32 a 57 meses (132).

Aunque esta mejoría puede ser atribuible a muchos factores, no hay duda de que el desarrollo de nuevos fármacos ha tenido un papel fundamental. Sin embargo, todavía existen importantes preguntas que contestar, particularmente en aquellas pacientes que desarrollan resistencia al tratamiento hormonal.

Las vías futuras de investigación incluyen el estudio y tratamiento de tumores con mutaciones en el RE, el hallazgo de biomarcadores, y el uso de biopsias líquidas, con la intención de desarrollar tratamientos personalizados que permitan mejorar la supervivencia de estas pacientes.

Conclusiones

La introducción y posterior evolución de muchos agentes endocrinos desde la década de 1970 ha transformado el tratamiento de las mujeres con CM (Figura 3).

Evolución cronológica de los descubrimientos en el tratamiento del cáncer de mama

Estos avances han logrado un cambio en la práctica clínica actual, pasando de cirugías ablativas y quimioterapias agresivas, a tratamientos dirigidos y mejor tolerados, lo que ha mejorado la supervivencia y la calidad de vida de las pacientes con CM.
