ABSTRACT

La decisión de administrar un tratamiento adyuvante del cáncer de mama en estadio inicial se fundamenta en la evaluación de varios factores pronósticos. El estado de los ganglios axilares, el tamaño del tumor y el grado de diferenciación histológico son las variables consideradas como clásicas, que se ven complementadas con el estado de los receptores hormonales y la expresión de HER2. Estos factores pueden combinarse con índices pronósticos para tener una estimación más precisa sobre el riesgo de recaída o de muerte asociada a la neoplasia. Otros parámetros individuales tienen una importancia secundaria. En los últimos años, a los factores clásicos se les han añadido los perfiles de expresión de genes, que permiten definir qué pacientes pueden prescindir de la quimioterapia adyuvante cuando el riesgo de recaída estimado es bajo. Se encuentran comercializados diferentes perfiles y se emplean de forma rutinaria en casos seleccionados. En el futuro, los perfiles génicos servirán para seleccionar grupos de pacientes que se beneficien de nuevos tratamientos dirigidos (AU)


Decision about the administration of adjuvant therapy for early breast cancer depends on the evaluation of prognostic factors. Lymph node status, tumor size and grade of differentiation are classical variables in this regard, and can be complemented by hormonal receptor status and HER2 expression. These factors can be combined into prognostic indexes to better estimate the risk of relapse or death. Other factors are less important. Gene profiles have emerged in recent years to identify low-risk patients who can forgo adjuvant chemotherapy. A number of profiles are available and can be used in selected cases. In the future, gene profiling will be used to select patients for treatment with new targeted therapies (AU)
