EORTC has a strong track record in initiating and conducting radiotherapy-based clinical trials across disease types. This follows the group’s strategy to challenge, re-define and develop standards of care for loco-regional treatments. Our scientific projects are designed and conducted to integrate disciplines such as imaging, translational research, quality of life and quality assurance.

The Radiation Oncology Group (ROG) is open to cooperative projects involving other EORTC groups and external cooperations, for example with neuro-oncology networks in Canada, Australia and the US. The group places special emphasis on recruiting and mentoring junior colleagues who are interested in pursuing an academic career in the field of radiation oncology.

In addition, EORTC runs an extensive Radiotherapy Quality Assurance programme (link to RTQA section) to ensure the consistency and reliability of imaging data across all EORTC clinical trials involving radiotherapy.

EORTC is also building a European network of Radiation Therapy Technologists, who are involved in clinical research and quality assurance projects.

Main Achievements

EORTC research in the field of radiation oncology has resulted in many advances in the discipline and in treating certain cancers, notably:

Major improvement in overall survival for locally-advanced prostate cancer by combining radiation with three years of androgen suppression. (link to publication)

Reducing the risk for symptomatic brain metastases in small cell lung cancer with prophylactic cranial irradiation. (link to publication)

Reduced risk of relapse in early breast cancer with an additional dose of radiotherapy. (link to publication)

The definition of a contemporary Quality Assurance benchmark for radiation trials

The establishment of technical guidelines to define irradiation volumes in several cancers

Established preoperative chemoradiation as the new standard of care for the treatment of locally-advanced, resectable rectal cancer (link to publication)
