Breakthrough Research Reveals New Hope in Colorectal Cancer Treatment and Prevention

Colorectal cancer is a significant health concern in the U.S. It’s the second leading cause of cancer deaths. This year, over 150,000 people are expected to be diagnosed, with nearly 53,000 dying from it, according to the American Cancer Society.

Recent studies shared at the American Society of Clinical Oncology (ASCO) meeting shine a light on both medication and lifestyle changes, particularly diet and exercise. While overall diagnoses are down due to better screening, young adults are seeing rising rates. It’s estimated that by 2030, colorectal cancer could become the main cause of cancer deaths among people aged 20 to 49.

A study published in the New England Journal of Medicine supports earlier findings that regular exercise enhances survival rates for colorectal cancer patients. Researchers tracked nearly 900 colon cancer patients from 2009 to 2024. Half received an informative booklet about healthy living. The other half worked with a physical activity consultant for three years.

The results were compelling: those who engaged in regular exercise had a 28% lower risk of cancer recurrence. Their five-year disease-free survival rate was 80%, compared to 74% for those who only received the booklet. This means exercise helped prevent 1 in 16 patients from developing new cancer. Dr. Christopher Booth, an oncology professor, emphasized that exercise should be a vital part of colon cancer treatment.

Experts are still exploring why exercise reduces cancer risks. One suggestion is that it lowers inflammation in the body. Another study presented at ASCO highlights how anti-inflammatory diets can also improve survival rates. Patients who focused on foods like leafy greens, coffee, and tea showed a 63% lower risk of death than those consuming diets high in red meat and processed foods.

According to Dr. Sara Char, a clinical fellow at Dana-Farber Cancer Institute, the increase in colorectal cancer cases among younger individuals indicates that lifestyle factors, including diet, play a crucial role. She noted the importance of understanding how food and habits affect cancer development and patient recovery.

Both Booth and Char agree that colorectal cancer patients often seek ways to manage their own risks. They find lifestyle changes empowering and achievable. A simple walking routine three to four days a week can make a significant difference.

Lifestyle interventions not only support patients but also help health systems by promoting sustainable care. However, access to necessary resources is crucial.

In addition to lifestyle changes, new treatments are emerging. Pfizer recently presented data on Braftovi, a drug that combines with chemotherapy to significantly extend survival in patients with advanced colorectal cancer. Those treated with this combo lived an average of 30 months compared to just 15 months with standard treatment.

Braftovi targets specific mutations that can lead to abnormal cell growth. Pfizer’s CEO emphasizes that these targeted therapies represent major advances in cancer treatment, making it easier to determine which patients may benefit.
