Avances en el tratamiento de cáncer de próstata resistente a la castración: énfasis en nuevas terapias hormonales

Resumen

Prostate cancer represents the second cancer-related cause of death in North American and Chilean men. The main treatment for incurable stages of disease is surgical or pharmacological castration. However, with time and despite the addition of anti-androgens, the disease progresses to a clinical state that has been commonly referred to as “hormone refractory”. In recent years, the concept of hormone refractoriness has been challenged and replaced by “castration resistance”, acknowledging that further and optimal hormonal manipulation can be attained, beyond achieving testosterone levels at castration range. The purpose of this review is to summarize the recent therapeutic breakthroughs in the management of metastatic castrate resistant prostate cancer (mCRPC), with greater emphasis in the newer hormonal therapy agents such as Abiraterone and Enzalutamide. Future combination and sequential treatment strategies are contextualized in the current era of personalized cancer medicine and genomic characterization of prostate cancer.
