Abstract

Background

The loco regional relapse is frequent in the lung disease. The aim of this study was to evaluate the outcomes of re-irradiation by SBRT in terms of Local Control (LC) and toxicities.

Methods

From April 2011 to December 2016, twenty-two patients received a re-irradiation by SBRT. Twenty- seven lesions were treated. The medium BED(10) of re-irradiation was 100.6 Gy (range: 48–151.2 Gy) and the medium EQD2(10) was 93.8 Gy (range: 40–126 Gy). In the previous treatment the medium BED(10) was 97.2 Gy (range: 40–120 Gy), the medium EQD2(10) was 81 Gy (range: 32.5–100 Gy). The median time between the first and the second treatment was 18 months.

Results

Local Control was reached in 18 out of 27 (66%) re-irradiated lesions, with rates of 67 and 54% at 1- year and 2- years respectively. The treatment was well tolerated; the maximum recorded toxicity was Grade 3.

Conclusions

Re- irradiation by SBRT may represent an option for the treatment of lung disease with good results in terms of LC and toxicity.
