Abstract :
Abstract In recent years, stereotactic ablative radiation therapy (SABR), also known as stereotactic body radiation therapy (SBRT), has gained a lot of attention as a potential alternative to surgical resection for certain patients with early-stage non-small cell lung cancer (NSCLC) or patients who cannot tolerate it. When it comes to early stage NSCLC, data from many clinical trials and retrospective studies show that SABR/SBRT is a safe and effective treatment that can compete with surgical resection. Compared to less harsh fractionation methods, the toxicities caused by ablative radiation doses are far more severe and difficult to tolerate. In view of these facts, it is essential to take into account a number of factors in order to accomplish high-quality treatment. The correct selection of patients is based on solid published evidence. The treatment is carefully planned to reach enough tumour coverage while avoiding organs-at-risk. The ablative radiation is delivered with care, using reliable immobilisation, accurately targeting the tumour, and verifying the dose delivery precisely.
