Pearson correlation analysis showed a positive correlation between serum CA19-9, CA125, CEA and CER, BV, BF, PS (P < 0.05), which suggested a correlation between the tumor markers and the CT perfusion parameters, however, the number of cases included in the current study is relatively small, and there is a need to further expand the sample size in future research. The gene discussed is CEACAM5; the disease is neoplasm.
