This paper summarizes some studies recently carried out in this Institute in the field of cancer chemotherapy.
Three main groups of data are reported:
a) different sensitivity to chemotherapy of the same tumor transplanted in different sites of the body;
b) a method to study cancer dissemination as a basis for cancer chemotherapy;
c) a system to perfuse tissue culture with the blood of living animals as an approach to study duration of action of antitumoral drugs.
