Changes in quality of life after surgery or radiotherapy in early-stage lung cancer

Surgical resection has been considered the standard of care and most effective treatment for early-stage non-small cell lung cancer (NSCLC) (1,2). However, approximately 25% of early-stage NSCLC patients do not undergo surgery due preexisting comorbidities, older age, or refusal (1,3). stereotactic body radiation therapy (SBRT), also known as stereotactic ablative radiotherapy (SABR), has been proposed in order to provide a minimally invasive treatment that improves accuracy in delivering ultra-high radiation doses (4). SBRT has become accepted and adapted as an alternative treatment for early-stage NSCLC (5-11)
