Colorectal cancer is a significant health issue within the United States, now recognized as the second most common conductor of cancer-related deaths. According to the American Cancer Society, it is anticipated that over 150,000 Americans will be diagnosed with colorectal cancer this year, and nearly 53,000 will succumb to the disease. These alarming statistics underscore the urgency for improved prevention, detection, and treatment strategies to address the needs of those affected.
Recent studies presented at the annual meeting of the American Society of Clinical Oncology (ASCO) offer a ray of hope regarding both pharmaceutical and lifestyle interventions. Notably, these studies examined the profound effects that diet and exercise could have on the prognosis of colorectal cancer patients. The long-term decrease in overall diagnoses of colorectal cancer has been largely attributed to advancements in screening. However, a troubling trend has emerged, as case rates appear to be increasing among younger adults. Research predicts that colorectal cancer could become the leading cause of cancer death among individuals aged 20-49 by 2030, marking a concerning shift that clinicians and researchers are actively addressing.
Several pivotal studies conducted in recent years have consistently demonstrated that regular physical activity can significantly improve survival rates for those diagnosed with colorectal cancer. This was recently confirmed in a new study published in the New England Journal of Medicine and presented at the ASCO conference. This research followed nearly 900 colon cancer patients who had completed chemotherapy between 2009 and 2024. Among these participants, half were given an informational booklet encouraging a healthy lifestyle, while the other half received additional support from a physical activity consultant for three years. The results were striking: patients engaged in the exercise program experienced a 28% reduction in cancer recurrence risk and an impressive five-year disease-free survival rate of 80%, compared to 74% for those adhering only to the booklet’s recommendations.
In practical terms, this means that the exercise program effectively prevented 1 out of every 16 patients from developing recurrent or new cancers. Dr. Christopher Booth, a professor of oncology at Queen’s University and a co-author of the study, emphasized the significance of these findings, stating that the benefits of exercise could rival those offered by traditional cancer drugs, thus establishing it as an essential treatment component for colon cancer.
While ongoing efforts aim to uncover the mechanisms behind exercise’s protective role against cancer, experts suggest that reduced inflammation in the body may be a noteworthy factor. An additional study presented at the ASCO conference indicated that anti-inflammatory diets, which include foods like coffee, tea, and leafy greens, could also enhance survival rates among individuals with stage 3 colon cancer. The research illustrated that patients consuming anti-inflammatory diets and maintaining higher physical activity levels had a 63% lower risk of mortality compared to those on more inflammatory diets rich in red and processed meats, refined grains, and sugary drinks.
Dr. Sara Char, a clinical fellow in Hematology and Oncology at Dana-Farber Cancer Institute, highlighted the importance of understanding the immune system’s role in colorectal cancer development, linking inflammation to cancer risk. Notably, the rise in colorectal cancer incidences among younger populations suggests that environmental factors, including diet and lifestyle choices, may significantly contribute to escalating rates, independent of genetic factors.
Both Dr. Booth and Dr. Char acknowledged the proactive interests of colorectal cancer patients who are eager to manage their risks comprehensively. Dr. Booth remarked on the empowering nature of these lifestyle interventions, emphasizing that patients can realistically commit to integrating exercise into their routines. The research included individualized “exercise prescriptions” tailored to each patient’s starting point; most individuals could achieve the recommended physical activity by briskly walking for an hour several times a week.
The role of medical systems in supporting patients as they engage in such interventions cannot be understated. Moreover, research presented during the ASCO conference highlighted innovative advancements in drug therapy. Notably, drug manufacturer Pfizer unveiled data on Braftovi, a colorectal cancer treatment that, in conjunction with standard chemotherapy and an antibody drug, demonstrated the ability to double the lifespan of patients suffering from aggressive tumors—an astounding increase from an average of 15 months to 30 months.
Braftovi functions through targeting a mutation within a specific protein that can induce abnormal cell growth, and it already holds approval by the U.S. Food and Drug Administration for treating certain cancer forms. Pfizer’s CEO, Dr. Albert Bourla, remarked on the significance of targeted therapies like Braftovi, stating that they represent substantial advancements in oncology over the past two decades. With plans to pursue further approvals to expand indications for the drug, Pfizer’s findings underline the critical importance of proactive measures in colorectal cancer treatment and recovery.
