Increased serum tumor biomarkers are usually associated with huge tumor burden, but the prognostic value of these markers remains controversial. The serum levels of carcinoembryonic antigen (CEA), nerve cell-specific enolase, and lactate dehydrogenase in 281 patients with small cell lung cancer (SCLC) were analyzed in this study. Increased serum CEA levels were observed in 92 (32.7%) patients. Survival was superior in patients with normal serum CEA levels compared with those with increased serum CEA levels. The median survival time, 2-year overall survival (OS) rate, and 3-year OS rate were 19.1 months vs 14.6 months, 42.7% vs 28.3%, and 30.6% vs 14.1%, respectively (P = 0.002). In multivariate analysis, extensive-stage (ES)-SCLC (hazard ratio [HR] = 1.936, P = 0.001), an increased serum CEA level (HR = 1.432, P = 0.021) at diagnosis, and <4 cycles of chemotherapy (ChT) (HR = 0.432, P = 0.001) were independent negative prognostic factors for the OS. Additionally, normal CEA level (HR = 1.678, P = 0.012), treatment modalities including surgery (HR = 1.595, P = 0.049), and ≥ 4 cycles of ChT (HR = 1.880, P = 0.004) were independent positive prognostic factors for OS in patients with local disease. In the subgroup with ES-SCLC, normal serum CEA level (HR = 1.608, P = 0.043), thoracic radiation therapy (HR = 1.744, P = 0.005), and ≥ 4 cycles of ChT (HR = 2.626, P = 0.001) were independent positive prognostic factors for OS.
