Clinical Trial Overview and Enrollment



Most of the advances in treatment and prevention of breast cancer have come from information gained through clinical trials. Fundamental concepts that are now taken for granted, for example, the equivalence of lumpectomy and mastectomy in early-stage breast cancer and the efficacy of endocrine therapy in estrogen receptor positive breast cancer, were not accepted until verified by clinical trials. Clinical trials can take various forms, whether the primary endpoint is assessing safety of a new drug, feasibility of a new technique, or head-to-head comparison of a promising treatment to a previously established standard with improvement in survival as the primary endpoint. An overview of the origins, development, and current embodiment of the major clinical trial groups which focus on breast cancer is provided.
