Impact of Salvage Surgery following Colonic Endoscopic Polypectomy for Patients with Invasive Neoplasia.

Salvage surgery following endoscopic polypectomy may improve the oncological survival of patients with invasive neoplasia, especially in patients with T1 stage. Furthermore, the T stage, size, and localization of polyps, as well as the level of CEA, could be identified as significant predictors for lymphonodal and distant metastases.
