The blood coagulation mechanism in general and the plasminogen system in particular
contribute to malignant growth and dissemination in complex ways. This article reviews
the extensive literature that has accumulated over the past half-century on effects
of plasminogen activation on the natural history of experimental animal and human
malignancy. Although the potent enzymes generated upon plasminogen activation may
have a direct effect on tumor cells, it is more likely that their mechanism of action
is related to disruption of the tumor cell-extracellular matrix interaction. These
observations suggest novel approaches to the experimental therapy of cancer.
