The Role of Carcinoembryonic Antigen After Neoadjuvant Chemoradiotherapy in Patients With Rectal Cancer

Abstract

Combined pre- and postchemoradiotherapy CEA levels could be useful as a prognostic factor for disease-free survival in patients with rectal cancer who undergo treatment with neoadjuvant chemoradiotherapy and curative resection. Postchemoradiotherapy CEA may be helpful in a selection of patients who want more conservative surgery after chemoradiotherapy.
