Evaluating which plan quality metrics are appropriate for use in lung SBRT.

CONCLUSION: Based on our study analyses, we recommend the following metrics as appropriate surrogates for establishing SBRT lung plan quality guidelines- Coverage % (ICRU 62), Conformity (CN or CIPaddick), and Gradient (R50%). Furthermore, we strongly recommend that RTOG lung SBRT protocols adopt either CN or CIPadddick in place of PITV ratio for conformity index evaluation. Advances in knowledge: Our study metrics are valuable tools for establishing lung SBRT plan quality guidelines.
