54. University of Texas MD Anderson Cancer Center
Headquarters: Houston, Texas
Bought By: Concord Medical Services
Headquarters: Beijing, China
Back in 2012, many eyebrows were raised when 20% of The University of Texas M.D. Anderson Cancer Center Proton Therapy Center was acquired by Beijing-based company Concord Medical services. Although the purchase didn’t directly affect the University’s ownership stakes, it did boost Concord’s profile.

“Proton treatment has become a widely accepted method of radiation therapy,” said Dr. Jianyu Yang, Concord Medical chairman and CEO. “Concord Medical plans to build and operate two proton centers in China. This transaction will enable us to gain valuable experience and knowledge of the operations of a proton therapy center from the world leader in proton therapy cancer care.”
