Exercise as Medicine: Strategies for Integrating Exercise into Cancer Care

Dr. Pedro Barata and Dr. Kathryn Schmitz discuss evidence-based exercise oncology programs, how to incorporate exercise into cancer care and connect the right patient to the right program, and ultimately build a culture of exercise in oncology. TRANSCRIPT Dr. Pedro Barata: Hello, and welcome to By the Book, a podcast series from ASCO that features compelling perspectives from authors and editors of the ASCO Educational Book. I'm Dr. Pedro Barata. I'm a medical oncologist and a clinical trialist at the University Hospital Seidman Cancer Center and an associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I'm also happy to serve as a deputy editor for the ASCO Educational Book. Today, we'll be talking about exercise. We have plenty of evidence that exercise benefits symptoms, improves the quality of life of patients, and actually has been shown to reduce risk of recurrence of cancer but also improve survival. And I think that's increasingly clear as data emerges. Today, I'm delighted to be speaking to Dr. Kathryn Schmitz. She's a leading expert on integrating exercise into cancer care. Dr. Schmitz serves as the deputy director of the University of Pittsburgh Hillman Cancer Center and also a professor of hematology-oncology at University of Pittsburgh Medical School. She's the senior author of a fantastic article in the ASCO Educational Book that's titled "Implementation Science as the Secret Sauce for Integrating Exercise Screening and Triage Pathways in Oncology." She also led a really compelling piece that just got published in JCO titled "If Exercise Were a Pill, We’d All Prescribe It to Patients With Cancer. But It's Not" So I'm thrilled to have Dr. Schmitz joining us today and helping us explore evidence-based exercise oncology programs, how to incorporate exercise into cancer care, and also how to connect the right patient to the right program. So with that, welcome, Dr. Schmitz. Thank you so much for taking the time to chat with us. Dr. Kathryn Schmitz: Thank you for the opportunity. Dr. Pedro Barata: One of the highlights of ASCO last year and practice changing, in my opinion, data out of The New England [Journal of Medicine] is called the CHALLENGE trial. It did provide high level evidence that a structured, supervised exercise program could improve both disease-free survival and overall survival. This is a study in the GI world, but I think it got a lot of attraction and attention beyond the GI world, across solid tumors, really. Could you give us a little brief recap of that trial and what have you seen as being the impact in practices around oncology? Dr. Kathryn Schmitz: So, CHALLENGE was very exciting. Prior to CHALLENGE, there were any number of observational studies that indicated that there was a relationship between being more physically active and reduced recurrence and improved overall survival for colon cancer in particular. You know, notably, in 2006, Jeff Meyerhardt published two papers in the same journal, of the same issue of JCO, showing very, very similar data from two very large studies. And those were studies number five and six in this area. You know, there's a lot of evidence observationally, but we don't generally change clinical practice on the basis of observational data. So, we were all waiting very impatiently for the results of the CHALLENGE trial. And it was very exciting to be in the front row when the results were reported out and to be part of the group with a standing ovation for the authors when it was presented. To summarize, 889 colon cancer patients, stage II and III, were randomized into either a structured exercise program or a health education control comparison group and followed for an average of 7.9 years. And the structured exercise group had a 27% reduced risk of recurrence and a 38% improvement in overall survival. One of the things that's really notable about this is that what we typically expect is that when we go from the observational literature to the clinical trial literature, that we expect effects to go down. We expect to see a larger effect in the observational than in the RCT land, and that did not happen here. We actually see an effect that matches what we've seen in observational literature, which is really, really exciting. And, you know, one of the reasons why this has been so exciting across not just GI but other cancers is the notable finding of a reduced risk of second primaries. So, they only observed two breast cancer second primaries in the treatment group and 12 in the comparison group. And overall, they reduced the second primaries occurrence, hazard ratio was 0.5, a 50% reduction of second primaries, which is just remarkable. It really got everybody very, very excited. And now the big question, of course, is, all right, how do I do this? How do I make this happen? The thing to note is that what they did in CHALLENGE is probably not doable...
