La radiothérapie (stéréotaxique…) et le cancer broncho-pulmonaire

New high-precision radiotherapy techniques allow a better adaptation to the tumor volume limiting the exposure of healthy organs and an increase in tumor dose. Among these techniques, stereotactic radiotherapy represents a fundamental change from the conventional fractionated radiotherapy. Dedicated systems including secure immobilization avoiding patient movement and accurate repositioning allows very high doses with high precision in one or few fractions. The results are encouraging with local control (80 to 100 % in 2 years) and survival (56 to 80 % at 2 years) rates very high in selected populations. The rate of late toxicity remains acceptable around 20 % of grade ≥ 3 at 2 years. We will focus in this article to describe the principle and the main results of the extracranial stereotactic radiotherapy of primary lung injury and pulmonary oligometastases.
