ABSTRACT

El cáncer de mama es la primera causa de muerte por cáncer en mujeres chilenas. Mientras la mayoría de las personas logra curarse de esta enfermedad, un 5% de los casos se presenta inicialmente con enfermedad avanzada y hasta un 20-30% de pacientes con enfermedad localizada pueden sufrir recurrencias sistémicas. La mayoría de las neoplasias mamarias son dependientes del estímulo estrogénico, de allí que la deprivación de estrógenos es la principal estrategia terapéutica. Recientemente, el uso de terapias molecularmente dirigidas en combinación con la terapia endocrina ha logrado mejorar los resultados de sobrevida del cáncer de mama avanzado, con menos efectos colaterales que aquellos producidos por la quimioterapia convencional. El conocimiento de los mecanismos de acción de estas nuevas terapias, sus toxicidades, vías de resistencia y selección de pacientes para lograr los mejores beneficios terapéuticos son aspectos relevantes en el manejo de la enfermedad. Presentamos una revisión del estado actual del manejo del cáncer de mama metastásico hormonodependiente con enfásis en el uso de terapias endocrinas combinadas con terapias moleculares.


Breast cancer is the leading cause of cancer death in Chilean women. While most patientes are cured, five percent of cases present with advanced disease initially and up to 20-30% of patients with localized disease may suffer systemic recurrences. The majority of breast neoplasms are dependent on the estrogenic stimulus, hence the deprivation of estrogen is the main therapeutic strategy. Recently, the use of molecular targeted therapies in combination with endocrine therapy has been successful in improving the survival outcomes of advanced breast cancer, with fewer side effects than those produced by conventional chemotherapy. Knowledge of the mechanisms of action of these new therapies, their toxicities, resistance pathways and patient selection to achieve the best therapeutic benefits are relevant aspects in the management of the disease. We present a review of the current state of management of hormone-dependent metastatic breast cancer with emphasis on the use of endocrine therapies combined with molecular therapies.
