Nine patients were alive and 15 irradiated tumors were controlled during the follow-up period of 10–54 months (median, 20 months). The overall survival rates at 1 and 2 years after SBRT were 90.0% and 62.2%, respectively.
The total biologically effective doses ranging from 50.7 to 157.5 Gy (median, 100 Gy) were given to the tumors by SBRT. Patients and Methods:Ģ1 patients who underwent SBRT for lung tumors within 2 cm from a major bronchus were retrospectively analyzed. The aim of this retrospective study is to investigate the safety and efficacy of stereotactic body radiotherapy (SBRT) for patients with lung tumors in the pulmonary hilum.
High-dose irradiation to the pulmonary hilar region is generally considered to be of high risk in causing bronchial injury.
