To investigate the diagnostic and prognostic significance of pro-gastrin-releasing peptide (ProGRP) in non-small cell (NSCLC) and small cell lung cancer (SCLC) and compare this marker with other known serum markers in lung cancer. ⋯ ProGRP is a useful marker in SCLC, with diagnostic performance better than that of NSE and demonstrating association with survival in NSCLC and SCLC limited to univariate analysis.
