The Role of Surgery in Lung Cancer Treatment: Present Indications and Future Perspectives—State of the Art

SIMPLE SUMMARY: Lung cancer evolutions, innovative systemic treatments, minimally invasive thoracic surgery approaches and perioperative medical care have changed the role of surgery in the treatment of lung cancer. Pre-invasive and early-stage lung cancer, and conversely, advanced and metastatic tumors can be treated by innovative imaging-guided resection, minimally invasive approach or hybrid approach with very good short-term outcomes, enhanced recovery and preserved long-term survival. Considering lung cancer as a chronic disease, surgery must anticipate future disease evolution by sparing lung tissue and preserving lung function, while an oncologic complete resection must be performed. Surgery could also be valuable when recurrences occur or for selected palliative conditions. This article outlines present indications and future perspectives of lung surgery in lung cancer. ABSTRACT: Non-small cell lung cancers (NSCLC) are different today, due to the increased use of screening programs and of innovative systemic therapies, leading to the diagnosis of earlier and pre-invasive tumors, and of more advanced and controlled metastatic tumors. Surgery for NSCLC remains the cornerstone treatment when it can be performed. The role of surgery and surgeons has also evolved because surgeons not only perform the initial curative lung cancer resection but they also accompany and follow-up patients from pre-operative rehabilitation, to treatment for recurrences. Surgery is personalized, according to cancer characteristics, including cancer extensions, from pre-invasive and local tumors to locally advanced, metastatic disease, or residual disease after medical treatment, anticipating recurrences, and patients’ characteristics. Surgical management is constantly evolving to offer the best oncologic resection adapted to each NSCLC stage. Today, NSCLC can be considered as a chronic disease and surgery is a valuable tool for the diagnosis and treatment of recurrences, and in palliative conditions to relieve dyspnea and improve patients’ comfort.
