Exercise and Diet Improve Cancer Patient Outcomes, New Studies Show

Exercise and Colon Cancer Survival

• 🏋️ A study in the New England Journal of Medicine found that colon cancer patients participating in a structured exercise program with a trainer had a 37% lower risk of death after 8 years.
• 🎯 The same study indicated that cancer was also less likely to recur in patients who exercised.
• 🏥 This structured exercise intervention, involving 889 patients across 50 centers, showed a 28% decrease in cancer recurrence and a 37% decrease in death risk at 8-year follow-up.
• 💰 The findings suggest a need for resources, insurance coverage, and health coaches to make such exercise programs accessible to patients.

High-Fiber Diet and Melanoma Treatment Response

• 🍎 A trial comparing high-fiber and lower-fiber diets in melanoma patients starting immunotherapy revealed significant differences in treatment response.
• 📈 Approximately 77% of patients on a high-fiber diet responded to their immunotherapy treatment, compared to only 29% in a control group.
• 🔬 This link is attributed to the gut microbiome, where bacteria that help break down fiber are associated with improved immunotherapy response.
• 🍽️ A controlled feeding study where patients received all meals from a metabolic kitchen for 10 weeks showed a marked improvement in tumor shrinkage rates for those on a high-fiber diet.

Lifestyle Interventions in Cancer Care

• 💡 For patients already diagnosed with cancer, improving lifestyle factors like diet and exercise can potentially synergize with treatments to improve outcomes.
• 🩺 While these lifestyle changes do not replace chemotherapy or immunotherapy, they should impact how healthcare providers support patients in improving their prognosis.
• 🔬 The research, including a small study of 43 patients and a larger phase three randomized study, provides encouraging evidence for the role of lifestyle in cancer treatment.
