Suboptimal Treatment Planning Adds Substantial Risk of Normal Tissue Complication: A Secondary Study on RTOG 0126

NCTN clinical trial standardization for radiotherapy through IROC and CIRO

Evidence-based practice is the cornerstone of modern medicine. Randomized clinical trials across multiple institutions are the gold standard for modern evidence collection. National Cancer Trials Network (NCTN) instruments the clinical trials through the new infrastructure for improvements in cancer treatment. Radiation therapy is an integral component of cancer treatment and is involved in many of the NCTN clinical trials. Radiotherapy is experiencing exciting developments in new treatment modalities and multi-modality image guidance. One of NCTN network groups NRG Oncology brings together the research areas of the National Surgical Adjuvant Breast and Bowel Project (NSABP), the Radiation Therapy Oncology Group (RTOG), and the Gynecologic Oncology Group (GOG). The Imaging and Radiation Oncology Core (IROC) and Center for Innovation in Radiation Oncology(CIRO) of NRG Oncology complement each other's functions in development and implementation of the new radiotherapy and imaging technologies in clinical trials with standardization and other strategies for quality. The standardization process is the essential step to make the data collected for clinical trials of high quality, interoperable, and reusable.
