Qualitative interviews with breast cancer and lymphoma patients receiving cardiotoxic chemotherapy revealed that altruism and provider recommendation drove enrollment, while intrinsic motivation, ease of participation, and positive study experiences supported completion, and symptom burden and lack of motivation were the main barriers to adherence.
Key Findings
Results
The main reasons participants enrolled in the physical activity intervention were altruism and provider recommendation.
18 breast cancer and lymphoma patients receiving potentially cardiotoxic chemotherapy completed semi-structured interviews
Participants were on average 53 years old (SD = 15)
The sample was 50% female (n = 9) and predominantly identified as White (n = 15, 83%)
Interviews focused on reasons for enrollment or dropout, perceptions of study personnel, experiences within the study interventions, and barriers to intervention adherence
Results
Participants reported completing the study because of intrinsic motivation, ease of participation, and positive study experiences.
Semi-structured interviews were audio recorded and analyzed using an integrative synthesis of the data
Key points and potential themes were identified from the qualitative data
Positive study experiences were identified as a factor supporting study completion
Ease of participation was cited as a facilitator of retention
Results
Participants reported favorable perceptions of the study interventions and study staff.
Perceptions of study personnel were a specific focus area of the semi-structured interviews
Experiences within the study interventions were also explored in the interviews
Positive study-staff relationships were identified as potentially enhancing study adherence and retention
Results
Barriers to adherence to the physical activity intervention included symptom burden and lack of motivation.
Barriers to intervention adherence were a specific focus of the semi-structured interview guide
Symptom burden was identified as a barrier, consistent with challenges of exercising during chemotherapy
Lack of motivation was also reported as a barrier to adherence
These barriers were identified among patients receiving potentially cardiotoxic chemotherapy
Discussion
Messages to enhance altruism and collaboration with providers may be important recruitment tools for cancer exercise trials.
Altruism was one of the main reasons cited for enrollment
Provider recommendation was the other main reason for enrollment
These findings suggest that recruitment strategies should leverage both patient-centered motivations and oncology provider networks
Conclusions
Developing positive study-staff relationships and delivering tailored, flexible interventions may enhance study adherence and retention in cancer exercise trials.
The study involved a tailored physical activity (PA) intervention
The qualitative data were used to optimize adherence and retention for a future randomized clinical trial
These strategies were described as contributing to the successful implementation of cancer exercise trials
The intervention was designed for breast cancer and lymphoma patients receiving potentially cardiotoxic chemotherapy
