Ventilatory efficiency during exercise has emerged as a strong predictor of major postoperative complications, so far determined during a maximal cardiopulmonary exercise test. However, this test is limited by its availability and high cost, due to the requirement of high-technological equipment and advanced expertise. The current project aims to evaluate a simplified and accessible method for risk evaluation before decision on treatment in lung cancer. It builds on recent advances in technology and knowledge and combines a simple, low-intensity cycling test with measurement of ventilatory efficiency (end-tidal carbon dioxide pressure) with a handheld monitor. In a prospective, multi-center design the investigators will include patients evaluated for suspected lung cancer. The main objective is to establish threshold values for end-tidal carbon dioxide associated with low respectively high risk of major complications in patients undergoing surgery. In addition, the study aims to determine if end-tidal carbon dioxide can predict severe side-effects during neoadjuvant or curatively aiming systemic therapy. The project is closely linked to clinical practice, and the results can be easily implemented due to the simple and cost-efficient methodology. the suggested simplified approach would also allow access to physiological evaluation where more advanced methods are unavailable.",[25,26,27,28,29,30],"Lung Cancer (Diagnosis)","Lobectomy","Surgery Complications","Neoadjuvant Chemoimmunotherapy","End-Tidal Carbon Dioxide","Exercise","NOT_YET_RECRUITING","2026-04-02",{"date":34,"type":35},"2026-04-08","ACTUAL",{"date":37,"type":20},"2026-04-01",{"date":39,"type":20},"2029-12",{"name":41,"class":42},"Linkoeping University","OTHER_GOV",5,""]
