MedicalResearch: What are the main findings of the study?

Dr. Sui: In the present study, cancer survivors who reported performing resistance exercise (RE) at least 1 day of the week had a 33% lower risk of all-cause mortality compared with individuals who did not report participation in resistance exercise.  Further, there was an inverse relationship between resistance exercise and all-cause mortality in those who were physically active, but not in those who were physically inactive.  Although leisure-time physical activity was not associated with a lower risk of all-cause mortality, the present results support the benefits of resistance exercise and physical activity was during cancer survival.

MedicalResearch: Were any of the findings unexpected?

Dr. Sui: Our results are consistent with previous literature demonstrating positive effects of exercise in cancer patients.  Physical activity (PA) is a modifiable risk factor known to decrease the occurrence of disease and all-cause mortality in healthy populations.  Additionally, regular PA can lead to the maintenance of and/or improvements in body composition, physical function, and overall quality of life in cancer survivors.

MedicalResearch: What should clinicians and patients take away from your report?

Dr. Sui: This is the first prospective study to examine the associations between resistance exercise and all-cause mortality in cancer survivors.  Although preliminary, clinicians should be aware of the long-term benefits of regular physical activity participation, especially resistance exercise in cancer survivors.

MedicalResearch: What recommendations do you have for future research as a result of this study?

Dr. Sui: Future prospective randomized controlled trials should be designed to address potential mechanisms between resistance exercise and health outcomes, including all-cause and disease-specific mortality, during cancer survival.
