Colorectal cancer is the second leading cause of cancer death in the United States for men and women, with an estimated 146,000 new cases per year - a staggering 53,000 patients die each year. Rectal cancer comprises a third of these patients, with a 5-year survival rate of 67%. Management of locally advanced rectal cancer in the U.S. had remained stagnant for more than a decade, with most of these patients being treated with long-course chemoradiotherapy, surgery followed by adjuvant chemotherapy; adjuvant chemotherapy being administered despite lacking a high level of evidence. Over the past few years, with rectal cancer death rates exceeding 30% from metastatic disease, growing interest focused on the attributes of induction chemotherapy to eradicate minimal residual disease and purportedly increase survival. This led to the development of Total Neoadjuvant Therapy. We now have high-quality data from randomized prospective trials to review the facts, fantasies, and fallacies of Total Neoadjuvant Therapy.
