Abstract

The invention relates to application of lobaplatin in preparation of drugs used for treating prostate cancer, especially to application of lobaplatin in preparation of drugs used for treating hormone refractory prostate cancer. An effective therapeutic dose of lobaplatin is 20 to 50 mg per square of a body surface area. According to the invention, a novel therapeutic drug is provided for treatment of prostate cancer, and clinical application of lobaplatin and a preparation thereof is broadened.

Description

technical field [0001] The invention relates to the application of lobaplatin in the preparation and treatment of prostate cancer, and belongs to the field of new application of chemical medicines. Background technique [0002] Prostate cancer is a malignant tumor that occurs in male prostate tissue and is the result of abnormal and disordered growth of prostate acinar cells. Prostate cancer incidence varies markedly by geographic and ethnic origin. In developed countries and regions such as Europe and the United States, it is the most common malignant tumor in men, and its mortality rate ranks second among various cancers; in Asia, its incidence rate is lower than that in Western countries, but it has shown a rapid upward trend in recent years. The etiology of prostate cancer has not yet been ascertained, and it may be related to various factors such as heredity, environment, and sex hormones. The secretory function of the prostate is regulated by the androgen testosteron...
