Can exercise help lung cancer patients before treatment?

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 at time of diagnosis; due to the rarity of the disease in those \<18 years, this age bracket will not be included. * Histologically diagnosed with stage II or III non-small cell lung cancer (NSCLC) and has not started lung cancer treatment. * Patient's treatment plan is to receive neoadjuvant therapy (defined as chemotherapy, chemotherapy and immunotherapy, or chemotherapy and radiation therapy) followed by surgical treatment. Patients will be enrolled at least three weeks prior to receiving their first neoadjuvant treatment. * Ability to follow directions and complete questionnaires in English and/or Spanish. * Ability to understand and the willingness to sign a written informed consent document prior to any study-related procedures. * Willing to travel to DFCI for necessary data collection. Exclusion Criteria: * Patients who are morbidly obese (BMI\>40 kg/m2) or Anorexic (BMI\<17 kg/m2). * Unstable comorbidities that contraindicate participation in exercise program compliance. Patients with unstable comorbidities may develop unexpected adverse events from exercise. For the purpose of patients' safety, as well as because part of this study involves remote, home-based exercise where close supervision is not possible, patients with unstable medical conditions are excluded. Study staff will identify untreated or unmanaged conditions when screening and treating MDs must provide clearance prior to patient enrollment. * Patients with alcohol or drug abuse, significant mental or emotional problems that would interfere with compliance (assessed by NCCN Distress Thermometer). * Patients scheduled to receive single modality cancer treatment (unimodal therapy), scheduled surgery within 2 weeks of the pre-treatment clinic visit, or for whom treatment has already started. * Patients who are pregnant, or plan to become pregnant during study duration will be excluded due to the unknown nature of exercise on developing fetuses. * Subjects who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study.
