According to an abstract to be presented at an upcoming conference, researchers from Harvard Medical School found that by adding the drug Zytiga to hormone therapy prior to surgery for men with locally advanced, aggressive prostate cancer, they could completely or nearly completely eradicate the disease in a third of patients in a recent trial.
Typically, locally advanced prostate cancer means high levels of prostate-specific antigen, an aggressive disease that has spread throughout the prostate, and a rather poor prognosis.
This Phase II trial involved 58 men who were given Zytiga along with Lupron (a hormone that stops testosterone production in the testes) for either three months or six months prior to undergoing surgery.
Preliminary results, released ahead of the American Society of Clinical Oncology (ASCO) meeting in Chicago in June demonstrated that among the 29 men who received the combination for six months, in three of the men, doctors could find no evidence of the cancer, and in another seven the disease was almost entirely eradicated.
Currently Zytiga is approved to treat advanced prostate cancer in patients who have already undergone chemotherapy.
