Inflammation-Based Prognostic System Predicts Postoperative Survival of Colorectal Cancer Patients with a Normal Preoperative Serum Level of Carcinoembryonic Antigen

摘要

Background Although carcinoembryonic antigen (CEA) is a valuable indicator for estimating the progression of colorectal cancer (CRC), some patients with advanced CRC show no elevation of the CEA level. On the other hand, inflammation-based prognosis, assessed by the Glasgow Prognostic Score (GPS), has been established as one of the important prognostic factors of survival after surgery for several types of cancer. We estimated the postoperative survival of CRC patients with a normal preoperative serum level of CEA on the basis of the GPS.
