    Studies

    Clinical research on breast cancer

    The care of patients participating in trials is an important quality factor of any breast center.
    Over the past decades, much has been achieved in the early detection, diagnosis and treatment of breast cancer. Most new insights come from studies in which the best-known therapies are compared with newer, and preferably even better, ones. During clinical trials, patients have the opportunity to be treated with promising new drugs and other forms of therapy. The focus here is always on women who have breast cancer.

    Studies conducted at the Breast Center are reviewed by the Ethics Committee of the Canton of Zurich and, where necessary, by Swissmedic. The medical personnel involved in the conduction of the studies are trained in accordance with internationally recognized guidelines.

    General
    information

    Studies help

    • avoid unnecessary therapies
    • obtain more detailed information about dose and effect
    • measure quality of life and side effects of therapy
    • assess additional examinations for their value
    • disseminate the new findings through a worldwide network of collaborating study groups
    • prolong life while preserving the quality of life

    Cultural conditions and personal circumstances are always respected. Holistic treatment is provided – even in the event that study participation is discontinued.
    The results of such studies are usually not available for several years, so the benefit to patients with breast cancer is not immediately apparent. A patient’s personal study data are always used in encrypted form for data protection.
