Comparison of tumor marker levels before and after treatment in the two groups of patients ($\overline{x}\pm s$).

Group	N	AFP (ng/mL)		CEA (ng/mL)		CA125 (U/mL)		SCCA (ng/ml)
		BT	AT	BT	AT	BT	AT	BT	AT
O group	43	4.08 ± 1.45	3.93 ± 1.24	2.96 ± 0.15	2.88 ± 0.35	16.54 ± 10.58	16.74 ± 9.28	3.56 ± 2.14	2.13 ± 1.12a
C group	53	4.18 ± 1.03	4.21 ± 1.87	2.58 ± 0.93	2.77 ± 0.71	15.67 ± 9.13	16.84 ± 7.46	3.68 ± 2.46	1.23 ± 1.05b
t		0.125	0.292	0.927	0.786	0.150	0.203	0.252	4.053
P		>0.05	>0.05	>0.05	>0.05	>0.05	>0.05	>0.05	<0.01

Note: comparison of the observation group before and after treatment, ^aP < 0.05; comparison before and after treatment in the control group, ^bP < 0.05. The levels of tumor markers were as follows, and there exhibited no significant difference in serum AFP, CEA, and CA199 levels before treatment (P > 0.05). The levels of AFP, CEA, and CA199 after treatment were lower than those before treatment. Compared with the two groups, the improvement of the observation group was significantly better than that of the control group.
