Although many patients with colorectal cancer are elderly, exclusion of these patients from randomized controlled trials has impeded the creation of evidence-based guidelines for this population. A study by Seymour et al demonstrated that elderly and frail patients with untreated metastatic colorectal cancer can participate in a randomized controlled trial. Study patients, who were considered unfit for full-dose chemotherapy, underwent a comprehensive health assessment and were started on chemotherapy at 80% of standard doses. [99]
