Percentage reduction of tumor weight at autopsy in the low dose treatment groups

Treatment group	Percentage reduction of tumor weight	P-value
Control
Brom (3.0 mg/kg) + Ac (300 mg/kg)	54.10±16.72	0.0005
GEM (2.0 mg/kg)	53.55±25.35	0.0035
GEM (2.0 mg/kg) + Brom (3.0 mg/kg) + Ac (300 mg/kg)	51.91±27.33	0.0056
5-FU (15 mg/kg)	10.93±30.15	0.4153
5-FU (15 mg/kg) + Brom (3.0 mg/kg) + Ac (300 mg/kg)	7.10±57.53	0.7745

Percentage reduction of tumor weight = [tumor weight (control) - tumor weight (treatment)/tumor weight (control)] ×100. Data are presented as mean ± SD; P-values were obtained through t-test; significance level: P<0.05.
