RESUMO
Patients with metastasis prostate cancer underwent androgen deprivation therapy (ADT) in the considering of the leading role of androgen receptor pathway. However, the resistance occurred within 1 year or more. The combination of cytotoxic chemotherapy and abiraterone for ADT therapy was performed in recent randomized controlled trials. The meta-analysis was focused on the treatment comparisons between additional treatment with ADT and ADT alone. A significant difference was observed that the overall survival benefit of early and active additional treatment with ADT in patients with hormone-sensitive metastatic prostate cancer. However, a great proportion of patients with metastatic disease have metastases after receiving ADT. It will be important to further improve the treatment options.
