Comparison of the CEA levels of the two groups of patients. Note: The abscissa represents before and after treatment, and the ordinate represents the expression level, mg/L; the expression levels of CEA before and after treatment in the control group were 74.23 ± 18.65 and (29.76 ± 7.85); the expression levels of CEA before and after treatment in the combination group were 74.05 ± 18.44 and 19.07 ± 5.09; indicates that the CEA expression levels of the control group patients before and after treatment were significantly different (t = 17.023, ); indicates that the CEA expression levels of patients in the combination group before and after treatment were significantly different (t = 22.263, ); indicates that the CEA expression levels of the two groups of patients after treatment were significantly different (t = 8.851, ).
