Simple Steps: Walking May Ease Colorectal Cancer Fatigue

Regular physical activity—especially walking—may improve fatigue and boost quality of life for people with nonmetastatic colorectal cancer during the first 2 years after diagnosis, according to research presented at ASCO Gastrointestinal Cancers Symposium 2026.

The study, which tracked over 1700 patients with colorectal cancer, found that those with nonmetastatic disease who walked for exercise 6-12 months after their diagnosis showed significant improvement in their fatigue scores over time. Their quality-of-life ratings rose in tandem.

The findings suggest that simple, sustained movement may play a meaningful role in long-term survivorship care, lead investigator Louisa Liu, MD, of Cedars-Sinai Medical Center in Los Angeles, said during a press briefing.

“Fatigue is one of the most common and debilitating symptoms our patients experience, often long after treatment ends,” Liu noted.

The new data, she said, show that an accessible form of exercise, especially when maintained over time, “can make a real difference in how patients feel and function during recovery.”

Joel Saltzman, MD, an ASCO expert in gastrointestinal cancers based at Taussig Cancer Center, Cleveland Clinic, Cleveland, agreed.

This is a “super-important study for all of us in the cancer community,” Saltzman told the briefing, especially in light of the CHALLENGE trial.

That study demonstrated that a structured exercise program can actually improve overall survival for patients with early-stage colon cancer who completed surgery and adjuvant chemotherapy.

“When you couple that with how patients feel, it really begs the question: Are we as a society doing enough cancer rehabilitation?” Saltzman said. “Everyone’s familiar with cardiac rehab, but oncologic rehabilitation is really something that really should be thought about in the future.”

Among long-term colorectal cancer survivors, nearly 40% continue to experience moderate-to-severe fatigue years after treatment — a challenge that affects functional recovery, daily activity, and quality of life.

“Yet,” Liu said, “our toolbox of effective interventions remains limited.”

Growing evidence supports physical activity as a nonpharmacologic approach for managing cancer-related fatigue. The mechanisms, Liu noted, may be multiple and include reductions in systemic inflammation, preserved muscle mass, better sleep quality and improvements in psychological stress.

In fact, current clinical guidelines recommend physical activity as part of survivorship care, but some key questions remain unanswered, Liu said.

“We still don’t fully understand when during recovery activity is most beneficial, what types of activity are best for different patients, or how these effects play out in real-world longitudinal settings, especially in colorectal cancer survivors,” she explained.

To address some of those gaps, Liu and colleagues analyzed data from 1718 patients with colorectal cancer (mean age, 67 years; 48% women) enrolled in the International ColoCare prospective cohort study. Nearly 1 in 5 had metastatic disease at diagnosis.

Physical activity was assessed at baseline and at 6, 12, and 24 months after diagnosis using a validated questionnaire. Participants’ total number of metabolic equivalent of task (MET) minutes per week — a measurement of energy spent during physical activity — were calculated for walking, moderate activities, and vigorous activities.

Total physical activity was categorized as low (fewer than 600 MET min/wk), moderate (600-3000 MET min/wk), or high (over 3000 MET min/wk).

Cancer-related fatigue and quality of life were measured using the European Organization for Research and Treatment of Cancer QLQ-C30 scale.

Overall, patients who were more physically active reported less fatigue and better quality of life as they moved further into recovery. And walking, Liu said, showed the “clearest and most consistent” association with these improved outcomes.

Among patients with nonmetastatic disease, those who reported regular walking 6-12 months after diagnosis showed significantly lower fatigue and higher quality-of-life scores over 2 years. Fatigue scores in this group improved steadily with time, from 32.5 at diagnosis to 29 at 12 months post-diagnosis and 26.8 at 24 months post-diagnosis.

Patients with metastatic disease also showed reductions in fatigue scores — from 40.7 at diagnosis to 37.1 at 12 months and 36.4 at 24 months — although those differences did not reach statistical significance.

Liu pointed out that patients with metastatic disease, not surprisingly, reported greater fatigue and poorer quality of life across all time points vs those with early-stage disease.

So, she said, “we don’t yet have strong evidence that physical activity changes the fatigue trajectory in the long run for metastatic patients. But this is an area where more targeted research is really needed.”

Looking at patterns of physical activity, the researchers found that activity levels at the time of diagnosis did not reliably predict long-term fatigue and quality-of-life outcomes. Instead, a patient’s activity level maintained between diagnosis and 1 year follow-up was a predictor of better outcomes.

“Short-term increases in physical activity didn’t seem to make a meaningful difference,” Liu said. “This suggests that when it comes to managing cancer-related fatigue, the key is to build steady, lasting habits that patients can stick with throughout their recovery.”

The study had no commercial funding. Liu and Saltzman had no disclosures.
