摘要
Management of locally advanced rectal cancer has evolved over time from surgical resection alone to multimodality therapy with preoperative radiation, chemotherapy, and total mesorectal excision resulting in excellent local control rates. Refinements in neoadjuvant therapies and their sequencing have improved pathologic complete response rates such that consideration of selective radiation and nonoperative management are now active clinical trial questions. Advances in radiation treatment planning and delivery techniques may allow for further reduction in acute treatment-related toxicity in select patient populations. Collectively, therapeutic strategies remain focused on improving outcomes for patients with higher-risk disease and reducing the morbidity of treatment.
