Table 4.

Density of the tumors from the low dose treatment groups determined at autopsy

Treatment group	Density (g/cm3)	% Change compared to control
Control	0.60
Brom (3 mg/kg) + Ac (300 mg/kg)	0.54	10% decrease
GEM (2 mg/kg)	0.59	2.0% decrease
GEM (2 mg/kg) + Brom (3 mg/kg) + Ac (300 mg/kg)	0.63	5.0% increase
5-FU 15 mg/kg	0.65	8.0% increase
5-FU (15 mg/kg) + Brom (3 mg/kg) + Ac (300 mg/kg)	0.60	No increase

Density = tumor mass/tumor volume (g/cm³). Percentage change of tumor density = [tumor density (control) - tumor density (treatment)/tumor density (control)] ×100.
