Total Neoadjuvant Therapy (TNT) in Rectal Cancer

Purpose of Review: This review summarizes the relevant literature on the use of total neoadjuvant therapy (TNT) for patients with locally advanced rectal cancer. It highlights the most notable literature published and briefly discusses future directions. Recent Findings: Recent randomized trials evaluating TNT show improved rates of pathologic complete response and patient treatment tolerance with this approach. Summary: The rationale for TNT includes the poor patient tolerance of adjuvant chemotherapy and the persistent risk of distant disease in patients with locally advanced rectal cancer, despite improvements in local control. Randomized trials have focused on short-term pathologic endpoints. Ongoing phase 3 trials are evaluating long-term disease-related outcomes, allowing for a more thorough evaluation of this treatment paradigm. TNT may also facilitate organ preservation in appropriately selected patients.
