Abstract
Organ preservation is considered in the management of selected patients with rectal
cancer. Complete clinical response observed after neoadjuvant chemoradiation for rectal
cancer is one of these cases. Patients who present complete clinical response are
candidates to the watch-and-wait approach, when radical surgery is not immediately
performed and is offered only to patients in the event of a local relapse. These patients
are included in a strict follow-up, and up of 70% of them will never be operated during
the follow-up. This strategy is associated with similar oncological outcomes as patients
operated on, and the advantage of avoiding the morbidity associated to the radical
operation. In this article we will discuss in detail the best candidates for this
approach, the protocol itself, and the long-term outcomes.
