Preoperative Treatment of Locally Advanced Rectal Cancer: Assets and Drawbacks of Short Course and Long Course in Clinical Practice

Preoperative short-course radiotherapy and preoperative long-course chemoradiotherapy are the standards of care for high-risk rectal cancer in different parts of the world. Both treatments are effective in local control and carry a low morbidity. The advantage of short course is its simplicity, whereas long course has the advantage of downsizing tumors thus increasing the chance of sphincter preservation. Although 2 randomized trials comparing short course and long course have been performed, the better form of preoperative treatment remains a subject of discussion.
