Anastrozole. An effective, second-line hormonal treatment for advanced breast cancer.

Because advanced breast cancer is not curable, the goal of treatment is to prolong survival yet maintain an acceptable quality of life. Anastrozole offers another option for second-line hormonal therapy in postmenopausal women with advanced breast cancer. This recently approved selective aromatase inhibitor is as efficacious as other available hormonal therapies for this indication and appears to offer an advantage with regard to adverse effects and ease of administration.
