To evaluate the value of plasma ProGRP, CYFRA 21-1 and CEA in patients with lung cancer. The levels of plasma ProGRP, CYFRA 21-1 and CEA were detected in 85 healthy control, 49 benign lung diseases and 143 lung neoplasms. The levels of ProGRP in the patients with SCLC was monitored. The level of plasma ProGRP in SCLC (M 179.1 ng/ml) was significantly higher than adenocarcinoma (M 35.3 ng/ml), squamous-cell carcinoma (M 33.3 ng/ml), healthy control (M 35.6 ng/m) and benign lung diseases (M 33.3 ng/m), P < 0.001. The sensitivity and specificity for diagnosing SCLC by ProGRP were 60.6% and 95.0% respectively. In the effective treatment group, ProGRP reduced 45.9%, in the progression group, ProGRP increased 103.1%, P < 0.05. The level of CEA in the metastatic adenocarcinoma (M 10.22 ng/ml) was significantly higher than non-metastatic adenocarcinoma (M 3.85 ng/ml) and squamous cell carcinoma (M 2.56 ng/ml) (P < 0.01). The plasma ProGRP is a good indicator for diagnosing and evaluating cure effect in SCLC; the high expression of CEA is related to the metastatic adenocarcinoma.
