Therefore, early diagnosis and positive treatment is crucial for the extension of overall survival in EC patients. We aim to investigate the feasibility of squamous cell cancer antigen (SCC-Ag), cytokeratin 21-1 fragment (CYFRA21-1), and carcinoembryonic antigen (CEA) in the diagnosis of postoperative LR in patients with EC, and the correlation between their expression and the prognosis of the disease. Methods: Sixty-two EC patients with postoperative LR were included, and thirty normal individuals served as normal control. Serum SCC-Ag, CYFRA21-1and CEA were determined before and one month after treatment. SCC-Ag level was evaluated using chemiluminescent microparticle immunoassay. CYFRA21-1 was determined using the chemiluminescence assay. CEA was determined using the direct chemiluminescence assay. The patients received radiotherapy and/or chemoradiotherapy. The survival rates were measured using Kaplan-Meier method, and was tested using Logrank analysis. Multiple logic regression analysis was used for the analysis of prognostic factors. Results: Remarkable elevation was noticed in serum SCC-Ag (t=4.79, P UR - https://tcr.amegroups.org/article/view/10091
