FORT MYERS, Fla., March 12, 2020 /PRNewswire/ — 21st Century Oncology, the largest integrated cancer care network in the nation, is entering into a joint venture partnership with Landmark Cancer Centers to increase patient access and advanced academic-level clinical care to cancer patients throughout the central United States. 21st Century Oncology will have a majority stake in the partnership while Landmark, located in Texas, Arkansas, Oklahoma and Missouri, will continue to oversee and lead business development efforts in central U.S. markets it currently operates.

Through the partnership, 21st Century Oncology will bring its best practices, quality oversight and expertise in cancer care to these new markets. Both organizations will continue to focus on achieving best possible outcomes for patients, supporting doctors and teams and expanding in all markets.

“21st Century Oncology looks forward to welcoming the Landmark physicians and team members to our ‘One Dream Team,'” said Chief Executive Officer Kim Commins-Tzoumakas. “We have been working on this combination for some time and I look forward to seeing what the two organizations can do together. The Landmark team has built an incredible organization and pipeline for expanding access to needed clinical cancer care across their region. Our new partnership, leveraging 21st Century’s broad network, academic-level cancer experience and operational infrastructure, will create a powerful combination that will support Landmark’s business acumen to grow the network and patient access even further in the future.”

The joint venture will add Landmark’s 12 cancer centers and five medical oncology offices across four states to 21st Century Oncology’s 123 radiation oncology treatment centers and 170 clinical offices in 15 states. What’s more, this transaction will add Landmark, and the central U.S., to the combination announced late last year between GenesisCare and 21st Century Oncology, expected to be complete later this spring.

Together, this partnership creates a global network of over 200 radiation oncology treatment centers and 170 clinical offices.

“This joint venture is exciting for our partner physicians, employees and patients by providing a fantastic platform for growth opportunities as well as continued excellence in patient care,” said Landmark’s founder and Chief Executive Officer Jon Tryggestad. “The 21st Century team shares our relational philosophy. We have always seen our purpose as being about people at every level and are excited to find a partner who shares this value.”

The transaction is expected to close following customary regulatory approvals.
