Inhibition of Secondary Tumor Growth by a Primary Pancreatic Cancer Tumor in an In Vivo Mouse Model.

Primary Tumor	Secondary tumor
	Lewis lung	HT1080	BxPC3
BxPC3	84%	73%	81%
ASPC-1	10%	7%	Not determined

Tumor cells were prepared and implanted into SCID mice. At the end of the experiment, tumor volume was measured. The volume of an inhibited tumor was compared to the volume of an uninhibited control tumor, and the ratio expressed as percentage inhibition. Thus, a secondary tumor having a volume that is 16% of the control tumor volume exhibits 84% inhibition in growth.
