Improving Rectal Cancer Outcomes with the National Accreditation Program for Rectal Cancer.

 The treatment of rectal cancer has undergone dramatic changes over the past 50 years. It has evolved from a rather morbid disease usually requiring a permanent stoma, almost exclusively managed by surgeons, to one that involves experts across numerous disciplines to provide the best care for the patient. With significant improvements in surgical techniques, the use of chemotherapy and radiotherapy, advanced imaging, and standardization of pathological assessment, the perioperative morbidity and permanent colostomy rates have significantly decreased. We have seen improvements in the quality of the specimen and rates of recurrence as well as disease-free survival. Rectal cancer, as demonstrated in European trials, has now been recognized as a disease best managed by a multidisciplinary team.  The aim of this article is to evaluate the main body of literature leading to the advances made possible by the new American College of Surgeons Commission on Cancer National Accreditation Program for Rectal Cancer.  Following the launch of the American College of Surgeons Commission on Cancer National Accreditation Program for Rectal Cancer, we expect dramatic increases in membership and accreditation, with associated improvement in center performance and, ultimately, in patient outcomes.  The National Accreditation Program for Rectal Cancer began in 2017. To date, the only data that have been analyzed are from the preintervention phase.  Based on the results of studies within the United States and on the successes demonstrated in Europe, it remains our hope and expectation that the management of rectal cancer in the United States will rapidly improve.
