Radiothérapie en conditions stéréotaxiques des cancers bronchiques localisés : principes et indications

Surgery remains the standard treatment for localized non-small cell lung cancer while the local control is optimal. For some patients, surgery is impossible due to comorbidities, especially in case of severe COPD. Stereotactic radiation is then a good option for these localized lung tumors without any nodes involvement. Peripheral lesions, but also central tumors can be treated providing less hypofractionated treatment. Due to hypofraction as well as its high precision, stereotactic radiation offers both a high quality of treatment and a well-tolerated treatment. Local control is high (> 80 %) and complications are limited. In contrast, survival data remain quite poor while patients die frequently of comorbidities or from metastatic progression.
