Summary

The purpose of this study is to evaluate the efficacy, quality of life and safety of switching from monthly (3.6 mg) or quarterly (10.8 mg) goserelin acetate (Zoladex®) to semiannual leuprorelin acetate 45 mg (Eligard® 45 mg) in prostate cancer patients with adequate hormonal castration level (plasma testosterone levels ≤50 ng/dL).

Detailed description

When systemic treatment is indicated, androgen deprivation therapy is the standard treatment for patients with prostate cancer. This condition occurs when the patient is diagnosed with metastatic disease or disseminated disease based on PSA values.The exchange of androgen hormone deprivation therapies in patients with metastatic prostate cancer may be required in different situations in clinical practice, such as: lack of medication available at the institution or on the market; alteration of the clinical protocol of the health institution due to economic factors and/or aiming to gain adherence to the treatment, often related to the posological convenience and/or logistics necessary for the administration of the medication, among others. Additionally, although there is evidence on the efficacy and safety of switching hormone treatments in patients with prostate cancer clinical data on this type of management of patients in Brazil are scarce. There are no data on how the management and switching of treatments is approached, nor on the clinical outcomes related to such a switch of therapy (time to progression, treatments used in combination with androgen deprivation therapy, time to onset of disease symptoms, time to start chemotherapy and costs involved).
