Can exercising at home before lung surgery be as good as going to a clinic?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age \> 18 years * Patient scheduled to undergo lung resection for the treatment of diagnosed or suspected bronchial cancer * Referred for prehabilitation before lung resection surgery * Patient living at home with another adult present during exercise sessions * Surgery date not established at the time of inclusion in the program, or at least 4 weeks away * Peak oxygen uptake below 20 ml/kg/min * Affiliated with a health insurance system * Able to read and understand the information letter and sign the consent form Non-Inclusion Criteria\*: * Oxygen therapy during exercise * Cardiological contraindication to exercise training * Refusal to participate in a center-based prehabilitation training program * Orthopedic, neurological, vascular, or neuromuscular conditions limiting exercise training on a cycle ergometer * Patient under guardianship or curatorship * Pregnant or breastfeeding women Exclusion Criteria: -Withdrawal of consent \*The eligibility criteria were revised in May 2026 following approval of a protocol amendment by the French Ethics Committee (CPP Île-de-France IV). The former non-inclusion criterion of patients receiving concomitant neoadjuvant chemoradiotherapy was removed to better reflect the study population to current clinical practice, as neoadjuvant treatments are increasingly integrated into the care pathway of patients undergoing thoracic surgery for non-small cell lung cancer and referred for pulmonary prehabilitation. The previous restriction had been too limiting and had slowed recruitment. This amendment was proposed to improve the feasibility of recruitment and to increase the representativeness of the study population, while ensuring the safety of the participants as no additional safety concerns were identified and all other exclusion criteria related to safety were unchanged.
