About The US Oncology Network

Affiliated Oncologists is a practice in The US Oncology Network (The Network). This collaboration unites the practice with more than 1,200 independent physicians dedicated to delivering value-based, integrated care to patients — close to home. Through The Network, these independent doctors come together to form a community of shared expertise and resources dedicated to advancing local cancer care and to delivering better patient outcomes. The Network is supported by McKesson Corporation, whose coordinated resources and infrastructure allow doctors in The Network to focus on the health of their patients, while McKesson focuses on the health of their practices. Affiliated Oncologists also participate in clinical trials through Sarah Cannon Research Institute (SCRI), a joint venture with US Oncology Research and one of the world's leading oncology research organizations conducting community-based clinical trials. Focused on advancing therapies for patients over the last three decades, SCRI is a leader in drug development. It has conducted more than 600 first-in-human clinical trials since its inception and contributed to pivotal research that has led to the majority of new cancer therapies approved by the FDA today.
