Research Network

International Cooperation in the treatment of Breast Cancer

The Breast International Group (BIG) was founded in 1996 and became an official international non-profit organization under Belgian law (aisbl) in 1999.

BIG’s mission is to facilitate the conduct of large and difficult breast cancer clinical trials and to reduce the wasteful duplication of efforts. Because BIG is ultimately not a “group” itself, but a “communications network” that enables its members to get together regularly to discuss and collaborate in research projects, BIG can be viewed as a “consortium of consortia”. BIG is a partnership among independent collaborative research entities that have their own data centres and extensive networks of affiliated investigators, hospitals and laboratories. Its 41 members, from Europe, Canada, Latin America, Australia / New Zealand and Asia, coordinate the BIG trials and are tied to approximately 3,000 specialized hospitals and research centres around the world.

The IBCSG is an active participant in the BIG.
