Lessons derived from A Prospective In-Silico Quality Assurance Study of Contouring Target Volumes within a Cooperative Group Setting: Insights from Radiation Oncologists’ Perspective

Target delineation variability is a significant technical impediment in cooperative group trials which employ IMRT and may impact outcome. The SWOG Radiation Oncology Committee conducted a prospective in-silico quality assurance pilot study based on the hypothesis that it is feasible to determine how diverse institutions participating in clinical trials are incorporating FDG PET-CT, 3D-, and 4D-CT data in RT planning.
