About this study

Official title: Evaluation of Non-Small Cell Lung Cancer Patients' Oxygen Uptake On-kinetics at Cycle-ergometer During Prehabilitation

In developed countries cancer has become the second leading cause of death after cardiovascular disease. The lung is a particularly exposed organ since broncho-pulmonary cancers rank second in terms of incidence, and the first rank in terms of mortality of all cancers listed in like reported in United States.

Lung resection surgery is currently the recommended curative treatment for the early stages of non-small cell lung cancer (NSCLC). Despite this preferred indication, some patients can not be eligible for surgery because of their cardiovascular or respiratory comorbidities or their impaired functional capacity.

Thus, the evaluation of aerobic capacity through cardiopulmonary exercise testing (CPET) of patients estimated at risk of postoperative complication is now recommended to estimate the level of predictive risk associated. The American Thoracic Society and the European Respiratory Socitety agree on thresholds of <10 and> 20 ml/kg/min of maximum oxygen uptake (VO2peak) respectively determining a high or low postoperative risk, between these two thresholds risk is considered moderate.

Aerobic capacity is traditionally expressed in terms of maximum oxygen uptake (VO2max or VO2peak) evaluated during an incremental CPET. In patients with significant respiratory impairment, these tests are often limited by ventilation and sub-maximally on the metabolic or cardiac parameters. However, the analysis of the VO2 kinetic during a constant-intensity test of moderate intensity is also a relevant way of measuring aerobic conditioning. Indeed, the time constant (τ) of phase II of VO2 kinetics (VO2τ) is a marker that closely reflects the adjustment of oxidative metabolism in skeletal muscle. Analysis of the kinetic parameters of the cardio-respiratory response to exercise has been shown to be reproducible and training-sensitive in patients with chronic obstructive pulmonary disease (COPD). The value of VO2τ was also reported to be strongly correlated with markers of severity and prognosis in COPD patients. Previous work has shown that exercise training can improve the speed of the VO2 kinetic response in COPD patients as well as in healthy subjects.

To date, no study to our knowledge has evaluated the kinetics of the cardiorespiratory response during moderate intensity constant-load test in patients with NSCLC. In this context, this work aims to evaluate the applicability of this measure as well as its evolution during a preoperative exercise training program in patients with NSCLC.

What participants receive

  • Preoperative Pulmonary RehabilitationOther

    Each prehabilitation session will last approximately 90 minutes and will include:

    Endurance training at the ventilatory threshold, determined according to the initial CPET. The first session will last for 15 to 20 minutes then increase by 5 minutes each session to reach 45 minutes in total (including a 5-minute warm-up and 5 minutes of active recovery). The intensity will then increase by 5 or 10 W, as could be tolerated;

    Peripheral muscle strengthening at 60% to 70% of the 1-repetition maximum of 3 main components (quadriceps press, whole-leg extension, and upper limb pull down). Three sets of 12 movements will carry out for each exercise and the load will increase weekly as tolerated;

    Inspiratory muscle training using a threshold calibrated to at least 30% of the MIP. Patients will be encouraged to carry out 15 minutes of independent training daily and to increase the resistance regularly.

    Education to bronchial drainage techniques as well as directed coughing.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase II time constant of Oxygen uptake kinetics (VO2τ), during a constant load test on a cyclo ergometer (time frame: before the preoperative training program). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
