What’s happening at OCSRI?
St. John Health System and Tulsa Cancer Institute have united to give Oklahomans a new level of confidence and hope. Together, we are Oklahoma Cancer Specialists and Research Institute.


Oklahoma Cancer Specialists and Research Institute exists to provide patients with the highest level of comprehensive cancer care. We are driven by our compassion for patients and their families; you have an ally in the fight against cancer.

We are connected to our patients, investing in their health and well-being throughout treatment and beyond. We are committed to pursuing advanced and innovative treatment methods. Cancer will give up before we will.

As Oklahoma’s only certified member of MD Anderson Cancer Network®, a program of MD Anderson Cancer Center, we are dedicated to the mission of eliminating cancer and upholding the highest standards of quality care. Our main campus in Tulsa underwent rigorous evaluations and clinical reviews to become a certified site in the MD Anderson Cancer Network.


Oklahomans don't have to travel far from home to receive the most up-to-date treatment options for cancer. We believe having the emotional support of family and friends nearby is an important part of successful therapy.
Oklahoma Cancer Specialists and Research Institute offers state-of-the-art outpatient oncology services in a compassionate, cost effective community-based setting.
