Is Surgery Always Necessary in Rectal Cancer?

Abstract

Rectal cancer is a major health problem around the world, representing about one-third of the total colorectal cancer cases. Because of its anatomical location, there is a higher risk of local recurrence, and treatment often requires a complex multidisciplinary approach which includes neoadjuvant radiotherapy, chemotherapy, and a radical surgical procedure that commonly leads to a permanent colostomy. The cure rate with this strategy is good, with some patients having no residual disease in the surgical specimen. While the prognosis for those Patients is excellent, their quality of life is permanently compromised. In this article, we review risks and benefits of the standard treatment approach and compare standard treatment with alternative methods aimed at rectal preservation.
