Can Exercise Be a Part of Cancer Treatment? | Dana-Farber Cancer Institute

To help reduce the risk of cancer, the American Cancer Society recommends at least 150 minutes a week of exercise or activity — a 30 minute walk each weekday, for instance — plus some strength training twice a week for good physical health.  

But researchers at Dana-Farber and other cancer centers are exploring the possibility that exercise could be specifically prescribed as medicine for cancer patients. Christina Dieli-Conwright, PhD, MPH, an exercise oncologist who runs the inaugural exercise oncology research laboratory at Dana-Farber, is investigating several exercise interventions that could help reduce side effects and improve outcomes for patients. 

“There’s a lot of excitement right now around the question of whether exercise can actually alter treatment-related endpoints,” says Dieli-Conwright. “Are those who exercise more likely to respond better to treatment?” 

Exercise as supportive medicine 

Much of the research around exercise and cancer has focused on patients who have completed therapy. Dieli-Conwright wants to intervene during treatment, while patients are taking medicines that might have difficult side effects.  

She is running several clinical trials to determine whether exercise could be a form of supportive care that alleviates symptoms and increases the chances that a patient might complete therapy. For instance: 

• The RE-BUILD Trial is investigating the feasibility of virtually supervised resistance exercise combined with protein supplementation to patients with pancreatic cancer who are receiving chemotherapy and may experience loss of skeletal muscle mass during treatment. 
• The CLARITY Trial is investigating the effects of high-intensity interval training (HIIT) for patients with early-stage breast cancer who are receiving chemotherapy to determine if the exercise intervention has an influence on cognitive function. 
• The MOBILTY Trial is investigating strength and aerobic training for patients with ovarian or endometrial cancer who are receiving chemotherapy to see if the exercise influences mobility or neuropathy, a form of nerve damage that can affect feeling in the feet and hands. 

Exercise interventions designed for marginalized groups 

Dieli-Conwright recognizes that patients from groups that have been historically marginalized in medicine can have reduced fitness levels, higher rates of obesity and heart disease, and higher risks of poor outcomes. Systemic marginalization results in lower levels of income, fewer resources for support and family care, and less access to medical care and wellness programs. All these factors together increase the chances that people from these groups will face health challenges.     

“We would be remiss to not focus on interventions that can specifically help people from groups that have been underrepresented in clinical trials,” she says. 

She currently has several clinical trials that include the involvement of family members, support groups with people from similar groups or backgrounds, transportation assistance, and more.  

These trials include: 

• The ROSA Trial offers virtually supervised exercise programs that focus on improving metabolic health for obese early-stage Latina breast cancer survivors. 
• The THRIVE Trial offers a 16-week exercise intervention designed to increase physical activity among Black and Hispanic breast, colorectal, or prostate cancer patients receiving chemotherapy.  
• The POWER Trial is focused on exercise and its ability to reduce cardiovascular disease risk factors in Black prostate cancer patients taking androgen deprivation therapy. 

Training for treatment 

The same way an athlete can prepare for a sporting event, patients can prepare for cancer treatment. Dieli-Conwright is interested in learning more about whether pre-habilitation exercise training helps patients prepare for and endure treatment. 

For example, the PROTECT Trial is examining the effects of an aerobic and resistance training program in patients with multiple myeloma who are scheduled to receive an autologous stem cell transplant.

Long-term vision 

Imagine infusion facilities, waiting rooms, and hospital wards that also have seamlessly integrated spaces for exercise. This is Dieli-Conwright’s vision of a world where exercise and movement are integral to the experience of clinical care.  

Yet Dieli-Conwright knows that not everyone is comfortable with exercising with others. While some of her trials offer in-person, in-clinic exercise interventions, others are offered virtually. She has evidence suggesting that adherence to the interventions is about the same either way, at a minimum of 80%.  

“Once people join an exercise trial, they participate,” she says. “People generally enjoy the physical benefits and having something positive they can do for themselves during treatment.”
