(Adds Siemens Healthineers comment, Commission declines comment, fourth source)
BRUSSELS/MUNICH, Feb 15 (Reuters) - German health group Siemens Healthineers is set to win EU antitrust approval for its $16.4-billion purchase of U.S. peer Varian Medical Systems Inc in a deal that will make it a world leader in cancer care therapy, four people familiar with the matter said.
Siemens Healthineers, spun off and floated in 2018 by Siemens, announced the acquisition in August last year. Varian is the leader in radiation therapy with a market share of more than 50%.
Siemens Healthineers last month offered concessions to address competition concerns about interoperability, the sources said. Such a measure enables computer systems and software to work with each other.
