title: Interplanner variability in carrying out three-dimensional conformal radiation therapy for non-small-cell lung cancer.
abstract: This study evaluated the variability among six radiation therapy planners in planning radiation treatment for four patients with lung cancer using two treatment protocols. The interplanner variability for target conformity and homogeneity was smaller than the variability among the patients and planning approaches. The same was found for the dose volume indices achieved for most critical structures, indicating that interplanner variability is not likely to be an important source of variation in radiotherapy studies if concise treatment protocols are followed.
