Abstract

High levels of serum carcinoembryonic antigen (S-CEA) are considered a negative prognostic factor in non-small-cell lung cancer (NSCLC), while the prognostic value of tumour CEA (T-CEA) is unknown. We investigated the prognostic role of T-CEA in radically resected early stage NSCLC. We measured preoperative S-CEA levels and T-CEA in 146 patients with stage 1-2 NSCLC, and analysed their influence on survival. In patients positive for T-CEA, 3-year survival was 80%, compared to 65% in T-CEA-negative patients (p = 0.03). After stratification by histology, T-CEA positivity was prognostic of better survival in squamous cell carcinoma (SCC) (p = 0.024) but not in adenocarcinomas (ADK) (p = 0.87). Multiple Cox regression analysis showed that T-CEA positivity was an independent predictor of better survival in patients with early stage NSCLC (p = 0.02). In SCC patients, the magnitude of the hazard ratio was confirmed even if the precision of the estimate is decreased (p = 0.06). In conclusion, T-CEA expression appears to be an important prognostic factor in early stage SSC of the lung.
