Figure 1

Comparison of serum levels (all serum levels data in this study were entered into excel software by the first author and the corresponding author, and the independent sample t test was performed using the mean ± standard deviation. The serum levels of ProGrp, CEA, CA211, and NSE were significantly higher in the observation group than in the comparison group (a) The serum levels of ProGrp, CA211, and NSE were significantly higher in the small-cell lung cancer observation group than in the squamous cancer and adenocarcinoma groups (b) and the serum levels were significantly lower in lung cancer patients in stage I and II than in patients in stage III and IV (c) with statistically significant differences ( > 0.05).
