Abstract:
Background and objectiveSerum carcinoembryonic antigen (CEA) and the soluble fragment of cyto-keratin 19 (CYFAR21-1) are important tumor markers (TMs) in the preoperative examination of patients with non-small cell lung cancer (NSCLC). However, the prognostic role of these markers in NSCLC patients remains controversial. hTe aim of the study was to investigate the clinical signiifcance of serum CEA variances and CYFAR21-1 levels for the prognosis of NSCLC patients following surgery.MethodshTis retrospective study investigated the clinical records and follow-up sessions of 175 patients with NSCLC who accepted surgery and adjuvant chemotherapy. Patients were subdivided into groups based on serum CEA and CYFAR21-1 levels. Survival analysis was conducted usingKaplan-Meier method for each group. hTe prognostic fac-tor was evaluated usingCox proportional hazards model.Results hTe overall survival (OS) of patients with high preopera-tive CEA or CYFAR21-1 levels was lower than that of patients with normal preoperative CEA or CYFAR21-1 levels. hTe OS displayed a signiifcant difference (P=0.001) between groups with high and normal preoperative CYFAR21-1. Compared with groups exhibiting normal preoperative and postoperative levels of CEA or CYFAR21-1, the OS was shorter for groups with high preoperative and postoperative levels of CEA or CYFAR21-1. hTe difference of the paired groups was signiifcant (P<0.05). Compared with the groups with normal preoperative and postoperative levels of CEA and CYFAR21-1, the OS was lower for the groups with high preoperative and postoperative levels of CEA and CYFAR21-1, which indicated a signiifcant difference (P<0.001). hTe CEACYFAR211 (HHHH), CEACYFAR211 (NNHH), CYFAR21-1 (HH), CEA (HH), and male genderwere identiifed as independent prognostic factors (P<0.05).ConclusionhTis study suggested that the prognosis of NSCLC patients was not signiifcantly satisfactory if preoperative and postoperative level of serum CEA or CYFAR21-1 was higher than standard value, especially if the preoperative and postoperative levels of CYFAR21-1 and CEA were higher than the standard values. hTe measurement of preoperative and postoperative levels of CYFAR21-1 and CEA proved helpful for the prognosis of patients with NSCLC.
