Vegetating Lesions that Appear in the Scar after Neoadjuvant Therapy for Rectal Tumors: Tumor Regrowth or Benign Neoplasm?

Abstract

Introduction After the diagnosis of neoplasm of the middle and distal rectum, patients are often submitted to oncological treatment by neoadjuvant therapy. At the end of this treatment, those patients who show complete clinical response can choose, together with their physician, to adopt the watch-and-wait strategy; although it implies lower morbidity for the patient, this strategy is dependent on strict adherence to treatment follow-up for the early identification of any future local injury.
