Androgen Deprivation Therapy (ADT) is a standard treatment for locally advanced or metastatic prostate cancer. It is also increasingly used in patients with high-risk localized prostate cancer or in patients with prostate-specific antigen (PSA) relapse after local therapy.
The luteinizing hormone-releasing hormone (LHRH) agonists, such as goserelin acetate(Zoladex®), have provided an effective and reversible means of suppressing androgen level. Zoladex® was originally formulated as a 3.6mg depot injection. Goserelin acetate 10.8-mg depot, given once every 3 months, is pharmacodynamically equivalent to 3 consecutive monthly injections of the goserelin acetate 3.6-mg depot, offers a more convenient and cost-effective dosing regimen for patients.
Goserelin acetate 10.8-mg depot has been available in China since 2012. However, data on the effectiveness and safety of the long-acting depot of Zoladex® (goserelin acetate depot) 10.8mg specifically in a Chinese population is limited. A "real-world" observational study is proposed to establish the effectiveness and safety profile of Zoladex ® 10.8mg in Chinese patients with localized or locally advanced prostate cancer.
