The general goal of the STARLighT study is to test whether a structured physical exercise and nutritional intervention significantly impacts clinical outcomes in patients with early-stage lung cancer. The main questions it aims to answer are: * Can structured physical exercise and nutrition intervention positively modify the pathological complete response in patients with early-stage lung cancer undergoing neoadjuvant treatments? * Can structured physical exercise and nutrition intervention positively influence disease-free survival in patients with early-stage lung cancer undergoing adjuvant treatments compared to usual care? This study will recruit two cohorts of patients. Cohort A will accrue patients who are candidates for neoadjuvant treatment and offer the opportunity to participate in a structured physical exercise and nutritional program, lasting the entire period of anticancer treatment. Cohort B will accrue patients who are candidates for adjuvant treatments. Patients will be randomized to receive 6 months of structured physical exercise and nutritional intervention or standard of care.
