Brief summary

The purpose of this research study is to compare the effects of music and different levels of device-guided breathing on anxiety and shortness of breath in lung cancer survivors.

Detailed description

OBJECTIVES 1. To assess feasibility (accrual, participation, adherence, retention) of a randomized study of device-guided breathing and music in 75 post-treatment lung cancer survivors with significant anxiety. 2. To obtain preliminary data on the variability and efficacy of two doses of a device-guided breathing intervention versus a music control group for reducing anxiety (primary outcome) and for improving self-reported dyspnea and respiratory functioning (secondary outcomes) in post-treatment lung cancer survivors. 3. To select the optimal dose of the device-guided breathing intervention (15 minutes once/day or twice/day) for subsequent randomized study.

Interventions

DEVICEGroup A - Device guided breathing low dose

Group A: 15 minutes once a day, 5 days a week for 12 weeks.

DEVICEGroup B - Device guided breathing high dose

Group B - 15 minutes twice a day, 5 days a week for 12 weeks.

DEVICEGroup C - Usual Breathing Control Group

Group C - 15 minutes per day, 5 days a week for 12 weeks.

Inclusion criteria

* Past History of any lung cancer * For Stage I-III disease, patients should be 2-24 months post-completion of surgery, radiation therapy and/or chemotherapy with no further planned treatment during the 12-week study and no evidence of disease. * For Stage IV disease, patients may be receiving no treatment or may be receiving maintenance treatment with a target agent, chemotherapy, or immunotherapy provided the most recent imaging does not demonstrate progressive disease. * After completion of all three screening questionnaires, participant must score accordingly on at least one questionnaire to be eligible. * Willing/able to attend brief introductory session and use assigned device for the assigned period of time (15 minutes once or twice per day), at least 5 days per week for 12 weeks * Age ≥ 18 years * Must have telephone

Exclusion criteria

* Patient does not understand English * Active lung infection * Progressive cancer (must be considered no evidence of disease or stable) * Any change in psychotropic medications in past 30 days * Hearing loss that would preclude participating in interventions. Adequate hearing to participate will be determined via: (1) Response of no to the question \[Do you have a hearing problem now?\] Participants with hearing aids will be allowed to enroll as long as their hearing is adequate to hear the sounds on the study devices. If necessary, potential study participants will receive a brief test trial with the RESPeRATE device. If they indicate inability to hear the guiding tones, they will not be enrolled in the study. Cortisol Exclusion \- Participants with endocrine disorders (e.g., diabetes and thyroid disorders) or on steroid-based medications are excluded from the cortisol portion of the study (with the exception of topical hydrocortisone that is permitted).

Design outcomes

Primary

MeasureTime frameDescription
Retention - Number of Participants Who Complete the Final Assessment12 weeksRetention will be calculated as the number of participants who complete the final assessment divided by number randomized.
Accrual Rate- Number of Patients Accrued to the StudyTime from study opening to study close ~46.42 monthsThe accrual rate will be calculated as the number of patients accrued to the study divided by the number of months of accrual.
Adherence- Amount of Time the Device is Used12 weeksAdherence will be calculated as the actual amount of time the device is used divided by the prescribed time. Successful adherence will be defined as use of the device ≥80% of the time assigned.

Secondary

MeasureTime frameDescription
Change From Baseline for Anxiety as Measured by Hospital Anxiety and Depression Scale (HADS)12 weeksTo obtain preliminary data on the variability and efficacy of two doses of a device-guided breathing intervention versus a usual breathing control group for reducing anxiety. This is a 14-item self-report measure of cognitive and behavioral symptoms of anxiety and depression; clinically significant symptoms are indicated by a score of greater than or equal to 8 with a range from 0 to 42. Higher scores indicate more anxiety.

Other

MeasureTime frameDescription
Salivary Cortisol Levels12 weeksCortisol levels will be assessed upon awakening, 30 minutes post-awakening, and at bedtime for three consecutive days at baseline and three consecutive days.
Gene Expression Levels12 weeksThe DNA methylation and gene expression patterns between the different groups.
DNA Methylation Levels12 weeksDNA methylation levels will be measured To determine if changes in anxiety are associated with methylation

Recruitment details

Implementation was facilitated through the Wake Forest National Cancer Institute Community Oncology Research Program (NCORP), developed to increase community participation in cancer trials. Forty-six participants were accrued between July 30 2015 and June 11 2019 (0.99 participants/month).

Pre-assignment details

In this feasibility study, participants were stratified by baseline self-reported dyspnea score and randomized to a 12-week high-dose or low-dose device-guided breathing intervention versus a usual breathing control group with equal probability, using variable length permuted block randomization. All participants enrolled were randomized and included in analyses.
