Feasibility of Implementing Cancer-Specific Community-Based Exercise Programming: A Multi-Centre Randomized Trial.

BACKGROUND: There is growing recognition of the importance of reporting preliminary work on the feasibility of a trial. The present study aimed to assess the feasibility of (1) a proposed fitness testing battery, and (2) processes related to the implementation of cancer-specific exercise programming in a community setting. METHODS/DESIGN: A randomized controlled implementation feasibility trial was performed in advance of a large-scale implementation study. Eligible participants within 18 months of a cancer diagnosis were randomized to immediate or delayed community-based exercise at YMCA locations in Calgary and Edmonton, Canada for an 8-week period. The primary outcome for the trial was the feasibility of the physical fitness testing battery, defined as a 70% or greater completion rate across the 24-week study period. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework was used to evaluate processes related to implementation of the exercise program across the two sites. RESULTS: Eighty participants were recruited, 73 (91%) completed the 8-week trial, and 68 (85%) completed the 16- and 24-week follow-ups. Sixty participants (75%) completed the full physical fitness test battery at each time point, and 59 (74%) completed the patient-reported outcome measures. Statistically significant between-group differences were found in favor of the exercise group for functional aerobic capacity, upper and lower extremity strength, and symptoms. Differences were found between the sites, however, in completion rates and processes related to program implementation. DISCUSSION: Findings suggest the need for minor adaptations to the physical fitness battery and outcome measures to better fit the community context. While findings support feasibility, context-specific challenges related to implementation processes were identified.

Therapeutic Ultrasound for Chemotherapy-Related Pain and Sensory Disturbance in the Hands and Feet in Patients With Colorectal Cancer: A Pilot Randomized Controlled Trial.

CONTEXT: This proof-of-concept trial was undertaken as a first step in exploring the clinical benefit of therapeutic ultrasound for pain and sensory disturbance in patients with colorectal cancer. OBJECTIVES: The aim of this study was to determine the feasibility and preliminary efficacy of adding therapeutic ultrasound to a home-based therapeutic exercise program (current standard of care) for patients presenting with oxaliplatin-related pain and sensory disturbance in the hands and feet. METHODS: Thirty-one colorectal cancer patients with presenting symptoms of peripheral sensory neuropathy, based on a physician-rated grade 1, 2, or 3 on the National Cancer Institute Common Terminology Criteria for Adverse Events for sensory and motor neuropathy, were enrolled in the trial. Patients were randomized to either 10 sessions of ultrasound therapy intervention over two-week period (continuous ultrasound at an intensity of 0.7 to 0.8 w/cm2, and frequency of 3 MHz for 5 minutes) plus standard care (n = 16) or to standard care alone (n = 15). The feasibility of therapeutic ultrasound was determined by the recruitment rate, participants' adherence to the intervention, and the study completion rates. Assessments of pain, sensory disturbance, sensation, and balance were conducted at baseline, two and six weeks. RESULTS: We achieved a recruitment rate of 84%, an adherence rate of 100% to the intervention, and a completion rate of 100%. Adding therapeutic ultrasound to standard care resulted in a statistically and clinically significant improvement in symptoms of pain and sensory disturbance (P = 0.003) at two weeks; however, no significance difference between the groups was found at the six-week follow-up. CONCLUSIONS: The findings of this proof-of-concept study support the feasibility of the therapeutic ultrasound in addition to standard care as an intervention for colorectal cancer patients with oxaliplatin-related pain and sensory disturbance in the hands and feet. The findings warrant a large-scale placebo-controlled trial.

Conservative and dietary interventions for cancer-related lymphedema: a systematic review and meta-analysis.

The findings support the use of compression garments and compression bandaging for reducing lymphedema volume in upper and lower extremity cancer-related lymphedema. Specific to breast cancer, a statistically significant, clinically small beneficial effect was found from the addition of manual lymph drainage massage to compression therapy for upper extremity lymphedema volume.
