feasibility, acceptability, and preliminary effects of lymfit

Conditions: Cancer Survivors; Lymphoma

Summary: background: lymphoma is one of the most diagnosed cancers in young adults aged 18 to 39. lymphoma is highly treatable, and the survival rate is often high. yet, cancer treatments can be toxic, and their side effects can negatively impact the quality of life among cancer survivors. the current research suggests that being active after treatment can improve cancer outcomes. for instance, reducing cancer-related fatigue, anxiety, depression, and improving sleep quality and survival. physical activities can greatly improve the quality of life after cancer treatment. knowledge gap: young adults are unique from cancer patients of other age groups. young adults need stage-of-life-specific, person-centred cancer and survivorship care. despite knowing that exercise is beneficial in improving cancer outcomes, cancer survivors' engagement and adherence to exercise guidelines remain poor. it is crucial to develop an effective intervention that can motivate lymphoma patients to be active after treatment. purposes: our study team developed a behavioural change intervention named lymfit. the lymfit intervention involves a personalized exercise program, bi-weekly kinesiology follow-ups, and the use of activity trackers. the aim of this study is to test if the design of the intervention is feasible and acceptable. the investigators also aim to test if the intervention is able to promote exercise motivation among young adult lymphoma survivors. implications: this 12-week pilot study examines the implementation strategies and clinical relevance of a behavioural change intervention targeting young adult lymphoma survivors. the study results have the potential to map out the optimal design of an effective physical activity intervention in improving cancer outcomes, and optimize post-cancer treatment care coordination among health professionals.

background: lymphoma and its subtypes are among the most commonly diagnosed cancers in young adults aged 18 to 39. most types of lymphoma are often treated with curative therapies. unfortunately, treatment side effects, and unhealthy or sedentary lifestyles can substantially affect quality of life and long-term cancer prognosis outcomes among young adult cancer survivors. a growing body of evidence reveals significant associations between physical activity and cancer-related outcomes. evidence suggests that specific frequency, intensity, timing, and types of physical activity can have positive effects on cancer treatment processes and outcomes. physical activity is also significantly associated with enhanced health-related quality of life among cancer survivors. despite sustained efforts in the development and implementation of exercise interventions geared towards specific cancer populations and age groups, evidence suggests that lymphoma survivors' exercise engagements remain suboptimal. this warrants the development of an intervention that is theoretically guided, and specific to cancer type and age, to enhance physical activity levels sufficient to improve cancer outcomes. grounded in self-determination theory, the lymfit intervention (an individualized exercise program with bi-weekly kinesiology assessments and an activity tracker device) supports the psychological need satisfaction of competence, relatedness, and autonomy in engaging physical activities. purpose: to evaluate the feasibility, acceptability, and preliminary effects of the lymfit intervention on participants' motivation to engage in exercise among young adult lymphoma survivors. methods: this study is a two-armed feasibility pilot randomized controlled trial. a target sample size of 28 young adult lymphoma survivors (at the end of their treatment up to six months post-treatment) will be randomly allocated to receive either the 12-week lymfit intervention (intervention group; n=14) or be on a wait-list (control group; n=14). feasibility will be assessed by examining criteria related to recruitment, randomization, retention, questionnaire completion, and intervention fidelity. acceptability will be assessed by examining participant satisfaction with the intervention and the perceived suitability of intervention delivery procedures. preliminary effects will be assessed using self-report questionnaires at baseline and post-intervention with four study outcomes: psychological need satisfaction, exercise motivation, physical activity level, and quality of life. implications: this study examines the feasibility and acceptability of the lymfit intervention. the results of this study are expected to help in mapping out the optimal design of an effective exercise program for improving cancer outcomes and quality of life in young adults with lymphoma. if the lymfit intervention shows desired effects, it will have to potential to offer nursing professionals an alternative care option to enhance the quality of post-treatment young adults cancer survivorship care.
