Background and aims:
People with rare cancers, lower survival prospects, and higher morbidity have been under-represented in exercise oncology trials. The ECHO-R trial evaluates the safety, feasibility and potential efficacy of a pragmatic, telehealth-delivered exercise program in the understudied population of recurrent ovarian cancer patients.
Methods:
50 women receiving chemotherapy for recurrent ovarian cancer were recruited to this pre-post, mixed-method exercise trial. The six-month intervention was delivered by Exercise Professionals via 12 telephone sessions and up to five in-person sessions. The weekly exercise intervention target was consistent with exercise oncology guidelines - 150 minutes of moderate-intensity, multimodal exercise - with prescribed volume and mode individualised. Primary outcomes were feasibility (minutes of exercise completed) and harms profile (exercise-related adverse outcomes) of the intervention. Secondary outcomes, assessed at baseline and post-intervention, included quality of life (FACT-O), fatigue (FACT-Fatigue), anxiety and depression (HADS), and neurotoxicity (FACT-GOG-NTX). 13 women participated in post-intervention qualitative interviews to provide a deeper understanding of factors influencing exercise participation.
Results:
The average minutes of weekly exercise completed did not meet the target (median 142 min/week, min: 0; max 533). 38% of the sample reported ≥1 harm (range 0-7 harms/person; no serious harms reported), with 71% of harms impacting exercise participation (11% moderate-major impact). There was no meaningful change in health outcomes observed between pre- and post-intervention. The importance of social support and the physical environment, the “hurdles” of side effects, the power of advice from health professionals, a “yearning” for the outdoors and a tendency to “resort” to walking emerged as qualitative themes influencing physical activity participation.
Conclusion:
Findings support that those delivering exercise therapy to people with recurrent ovarian cancer should focus on each person’s “why” and that factors influencing exercise participation may be more psychosocial than physical.
