Brief summary

People who responded to the World Trade Center (WTC) disaster on September 11, 2001 were exposed to toxic dust and smoke and have higher rates of certain health problems, including prostate cancer. Many WTC Responders with prostate cancer experience ongoing physical limitations, fatigue, and reduced quality of life, even after completing cancer treatment. Regular exercise can improve strength, balance, physical function, and well-being in people with cancer, but many men with prostate cancer do not meet recommended physical activity levels. Barriers such as travel, health concerns, and lack of access to tailored programs can make it difficult to participate in exercise programs. This pilot study will test whether a remotely delivered, supervised group exercise program is feasible and acceptable for WTC Responders with prostate cancer. The exercise program is delivered live by videoconference and is based on an established, evidence-based program for older adults. It includes aerobic, strength, balance, and flexibility exercises and is designed to be safe, supportive, and accessible to people living in different locations. A total of 40 WTC Responders with a history of prostate cancer will take part in this study. Participants will be randomly assigned to either (1) a 16-week remote exercise program or (2) a waitlist control group that receives usual care during the study period and is offered the exercise program after completing all study assessments. Participants in the exercise group will attend three one-hour exercise sessions per week using videoconferencing. The main goals of this study are to determine whether participants can be successfully recruited and retained, whether they attend and complete the exercise sessions, and whether they find the program acceptable and helpful. The study will also explore whether the exercise program improves physical function, physical activity, and quality of life. Physical function will be measured using simple movement tests performed remotely, and physical activity will be measured using a wearable activity monitor. Participants will also complete questionnaires about their health, physical functioning, and experiences with the program. In addition, this study will evaluate whether it is feasible for participants to collect saliva samples at home and return them by mail for future research. A subset of participants will be invited to complete interviews to share their experiences and provide feedback on how the program could be improved. Results from this pilot study will help inform the design of a larger future trial aimed at improving physical function and quality of life for WTC Responders with prostate cancer through accessible, remotely delivered exercise programs.

Secondary

MeasureTime frameDescription
Change in Fatigue Measured by PROMIS-29Baseline and Week 16PROMIS-29 Fatigue T-score. Higher scores indicate worse fatigue.
Change in Sleep Disturbance Measured by PROMIS-29Baseline and Week 16PROMIS-29 Sleep Disturbance T-score. Higher scores indicate worse sleep disturbance.
Change in Pain Interference Measured by PROMIS-29Baseline and Week 16PROMIS-29 Pain Interference T-score. Higher scores indicate greater pain interference.
Change in Anxiety Measured by PROMIS-29Baseline and Week 16PROMIS-29 Anxiety T-score. Higher scores indicate worse anxiety.
Change in Average Daily Step Count Measured by activPAL AccelerometerBaseline to 16 weeksAverage number of steps per day measured using a thigh-worn activPAL accelerometer worn continuously for 7 consecutive days.
Change in Depression Measured by PROMIS-29Baseline and Week 16PROMIS-29 Depression T-score. Higher scores indicate worse depressive symptoms.
Change in Ability to Participate in Social Roles Measured by PROMIS-29Baseline and Week 16PROMIS-29 Ability to Participate in Social Roles T-score. Higher scores indicate better social participation.
Change in Functional Capacity Measured by Duke Activity Status Index (DASI)Baseline and Week 16Duke Activity Status Index (DASI) total score estimating functional capacity. Higher scores indicate greater functional capacity.
Change in Short Physical Performance Battery (SPPB) Total ScoreBaseline to 16 weeksTotal composite score (range 0-12) derived from balance, gait speed, and chair stand components of the Short Physical Performance Battery. Higher scores indicate better physical performance.
Change in SPPB Balance ScoreBaseline to 16 weeksBalance subtest score (0-4) from the Short Physical Performance Battery. Higher scores indicate better balance performance.
Change in Timed Up and Go (TUG) Test TimeBaseline to 16 weeksTime in seconds required to stand from a seated position, walk 3 meters, turn, return, and sit down. Lower values indicate better mobility.
Change in Two-Minute Step Test PerformanceBaseline to 16 weeksNumber of step-raises completed in two minutes, meeting standardized knee-height criteria. Higher values indicate better aerobic endurance.
Change in Five-Times Sit-to-Stand (5xSTS) TimeBaseline to 16 weeksTime in seconds required to complete five consecutive sit-to-stand repetitions from a standard chair without use of arms. Lower values indicate better performance.
