High-Flow Oxygen in Reducing Shortness of Breath Caused by Exercise in Patients With Cancer

December 5, 2022 updated by: M.D. Anderson Cancer Center

High-Flow Oxygen for Exertional Dyspnea in Cancer Patients

This randomized phase II trial studies how well high-flow oxygen works in reducing difficulty breathing during exercise (exertional dyspnea) in patients with cancer. Dyspnea is linked to decreased lung function, quality of life, and survival. High-flow oxygen is a device that delivers heated and humidified oxygen through the nose. This may be effective in reducing dyspnea, and may help patients' lungs function better and improve their quality of life.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Obtain preliminary estimates of the effect size of oxygen and high flow rate on exertional dyspnea (modified Borg Scale adjusted for work rate and baseline dyspnea).

SECONDARY OBJECTIVES:

I. Determine the completion rate of a randomized controlled trial of exertional dyspnea in cancer patients.

II. Obtain preliminary estimates of the effects of oxygen and flow rate on physiologic function (respiratory rate and oxygen saturation) and exercise capacity (work rate and exercise duration).

OUTLINE: All patients undergo a baseline structured exercise session with air. Patients are then randomized to 1 of 4 treatments for a second session approximately 3 days later.

ARM I: Patients receive high-flow oxygen via nasal prongs during a structured stationary bicycle exercise session.

ARM II: Patients receive high-flow air via nasal prongs during a structured stationary bicycle exercise session.

ARM III: Patients receive low-flow oxygen via a nasal cannula during a structured stationary bicycle exercise session.

ARM IV: Patients receive low-flow air via a nasal cannula during structured stationary bicycle exercise session.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modified Borg Scale Dyspnea Intensity at Isotime
Time Frame: End of second exercise test and end of third exercise test, approximately up to 12 minutes
Assessed Dyspnea using the Modified Borg Scale Dyspnea Intensity that ranges from 0 ("no shortness of breath") to 10 ("worst possible shortness of breath") at Isotime. Measured the mean difference of Modified Borg Scale Dyspnea Intensity at isotime between the second exercise test (in which all patients received Low Flow Oxygen) and the third exercise tests (in which all patients received the assigned intervention).
End of second exercise test and end of third exercise test, approximately up to 12 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Slope of Modified Borg Scale Dyspnea Unpleasantness Over Time During Constant Work Exercise Per Minute (Third Test)
Time Frame: Third exercise test, approximately up to 12 minutes
Dyspnea unpleasantness was measured using the Modified Borg Scale Dyspnea Intensity that ranges from 0 ("no shortness of breath") to 10 ("worst possible shortness of breath"). Dyspnea intensity was measured every minute. The number of minutes varied by patient, per test. It was measured as pairwise difference of slope (taking 'low flow air' arm as a reference). This linear mixed model was constructed based on the following: Dyspnea Unpleasantness at third test = Minutes + Study Arm + Study Arm*Minutes + Total work rate + Slope of Dyspnea Unpleasantness and Minutes at Second test + Minutes at second test.
Third exercise test, approximately up to 12 minutes
Modified Borg Scale Leg Discomfort
Time Frame: Third exercise test, approximately up to 12 minutes
Leg discomfort was measured using the Modified Borg Scale Leg discomfort that ranges from 0 ("no discomfort") to 10 ("worst possible discomfort") during the constant work exercise of third test. Leg discomfort was measured every minute. The number of minutes varied by patient, per test. It was measured as pairwise difference of slope (taking 'low flow air' arm as a reference). This linear mixed model was constructed based on the following: Leg Discomfort at third test = Minutes + Study Arm + Study Arm*Minutes + Total work rate + Slope of Leg Discomfort and Minutes at Second test + Minutes at Second test.
Third exercise test, approximately up to 12 minutes
Exercise Endurance
Time Frame: End of third exercise test, approximately up to 12 minutes
The Exercise endurance was measured as a mean duration of constant work in minutes during third test. It was measured as pairwise comparison of mean difference of exercise duration (taking 'low flow air' as a reference). This linear mixed model was constructed based on the following: Time at third test = Study Arm + Minutes at Second test. Detail output from the mixed models
End of third exercise test, approximately up to 12 minutes
Adverse Events
Time Frame: Before and after 3rd test during intervention phase, approximately up to 12 minutes
Adverse effects related to supplemental oxygen use were assessed using a numeric rating scale from 0 (not at all) to 10 (worst possible) before and after the study intervention. The mean change was measured before and after the 3rd test ranging between -10 (improvement) and +10 (deterioration).
Before and after 3rd test during intervention phase, approximately up to 12 minutes
