Inhibitory effect of arsenic trioxide on angiogenesis and expression of vascular endothelial growth factor in gastric cancer

Table 1 Tumor growth inhibition (TGI) of tumors treated with arsenic (n = 10, mean ± SD)

Group	Tumor volume (V) mm3			Mass(mg)	TGI (%)
	D 0	D6	D11		D6	D11
Control	67 ± 45	343 ± 160	999 ± 338	784 ± 185
2.5 mg/kg	63 ± 36	307 ± 80	696 ± 125a	556 ± 211a	11.7%	30.3% (29.1%)
5 mg/kg	66 ± 48	240 ± 203	491 ± 116ac	375 ± 167ac	30.0%	50.9% (52.2%)

^aP < 0.05 vs control;

^cP < 0.05 vs 2.5 mg/kg; TGI calculated using tumor volume was given in parenthesis.
