Esophagus toxicity after stereotactic and hypofractionated radiotherapy for central lung tumors: Normal tissue complication probability modeling

As no grade 3-5 esophageal toxicity was observed in our cohort, a Dmax of 56 Gy EQD210 and a D5cc of 35.5 Gy EQD210 could be delivered without high risks of severe toxicity. The NTCP models of this study might be used as practical guidelines for the treatment of central lung tumors with stereotactic radiotherapy.
