In the last 15 years, the use of Stereotactic Ablative Radiation Therapy (SABRT) in the management of small peripheral lung tumours has developed considerably, so that it currently represents a standard of care for inoperable stage I non-small cell lung cancer (NSCLC), offering a survival advantage over traditional radiotherapy, local control rates at 3 years around 90%, with a low risk of toxicity. Indications have extended to larger tumours up to 5 cm and centrally located tumours. In this review we will explore the role of SABRT in early stage NSCLC, the state of the art, the challenges and the future for this technique. There are ongoing studies to optimize such approaches within a multicentric setting. Trials comparing surgery to SABRT in operable or marginally operable have failed because of poor accrual. Several questions remain that need to be addressed in prospective studies.

Background: The use of local consolidative therapy (LCT) in patients with oligometastatic non-small cell lung cancer (NSCLC) is rapidly evolving, with a preponderance of data supporting the benefits of such therapeutic approaches incorporating pulmonary resection for appropriately selected candidates. However, practices vary widely institutionally and regionally, and evidence-based guidelines are lacking.
Methods: The Society of Thoracic Surgeons assembled a panel of thoracic surgical oncologists to evaluate and synthesize the available evidence regarding the role of pulmonary resection as LCT.

Background: Non-small cell lung cancer (NSCLC) is a fatal disease, and radioresistance is an important factor leading to treatment failure and disease progression. The objective of this research was to detect radioresistance-related genes (RRRGs) with prognostic value in NSCLC.
Methods: The weighted gene coexpression network analysis (WGCNA) and differentially expressed genes (DEGs) analysis were performed to identify RRRGs using expression profiles from TCGA and GEO databases.

Chronic obstructive pulmonary disease (COPD) is among the most relevant comorbidity associated with lung cancer. The advent of innovative triple treatment approaches for COPD has significantly improved patients' quality of life and outcomes. Few data are available regarding the impact of triple inhaler therapy on patients featuring COPD and lung cancer.
