NRG Oncology established Center for Innovation in Radiation Oncology (CIRO) to achieve the following aims:

1) Promote innovative Radiation Therapy (RT) research within the entire National Clinical Trials Network (NCTN)

  • Accelerate the testing of new radiation oncology innovations in NCTN clinical trials in all groups
  • Facilitate the application of innovations across all appropriate protocols

2) Foster intergroup collaboration and protocol harmonization in terms of inclusion and description of RT techniques and delivery devices

  • Reduce timelines for development of new protocols
  • Improve the clarity of NCTN protocols


Radiation oncologists and medical physicists collaborate and provide the documents and tools listed on this webpage.
