Home workouts could speed lung cancer recovery, new study says

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

Inclusion Criteria: 1. Age ≥ 18 years. 2. Histological or cytological diagnosis of lung cancer (resectable stage according to the multidisciplinary team). 3. Patients scheduled for lung surgery with curative intent (lobectomy, segmentectomy, pneumonectomy, etc.). 4. Ability to understand and sign informed consent. 5. Clinical condition that allows participation in a supervised exercise program, according to medical evaluation, with an ECOG performance status of 0-2 (Eastern Cooperative Oncology Group Performance Status). 6. Availability to perform the scheduled measurements and follow-ups (preoperative and postoperative). 7. Ability to use the mobile application or have family support to do so. Exclusion Criteria: 1\. Absolute medical contraindications to supervised physical exercise, such as unstable angina, recent decompensated heart failure, uncontrolled arrhythmias, or acute cardiovascular events within the last 3 months. 2\. Very advanced chronic lung disease that prevents participation in the program (e.g., severe COPD with FEV1 \< 30% predicted, as determined by the clinical team). 3\. Distant metastases or metastatic cancer that contraindicate surgery with curative intent. 4\. Planned palliative surgery or life expectancy \< 3 months. 5\. Home oxygen therapy with severe, uncorrectable hypoxemia, as determined by clinical judgment. 6\. Moderate-to-severe cognitive, neurological, or psychiatric impairment that prevents understanding of the study or proper use of the mobile application. 7. An insurmountable language barrier that prevents understanding the study information or using the mobile application. 8\. Pregnancy. 9\. Participation in another interventional clinical trial that may interfere with the study objectives or its primary outcome. 10\. Any other condition that, in the opinion of the research team, compromises the participant's safety or adherence to the protocol. Withdrawal Criteria 1. Withdrawal of consent. 2. Adverse events that contraindicate continued exercise (clinical decision). 3. Failure to complete more than 30% of planned sessions (for per-protocol analysis; continue in ITT).
