Colorectal cancer is the third most common cancer worldwide, and more than half of those newly diagnosed with colon cancer are over the age of 70 years. Despite the large proportion of patients over the age of 70 diagnosed with colon cancer annually, this age group is significantly underrepresented in clinical trials and, therefore, there is little high-quality evidence on which to base treatment decisions or treatment guidelines. This article reviews the management of primary colon cancer in older adults, including screening, presentation and diagnosis, treatment, and follow-up in this population.
Key words: colon cancer, colorectal cancer, screening, tumour, older adults.
