[Potentiation of the antitumoral effect of electrochemotherapy by immunotherapy with allogeneic cells producing interleukin 2]
Abstract
Electrochemotherapy (ECT) is a new antitumour treatment which consists of delivering electric pulses to the tumour a few minutes after an intravenous injection of bleomycin. The antitumour efficacy of ECT is increased by local injections of interleukin 2 (IL2) in the oedema which appears at the site of the treated tumours. We have shown that tumour cells inoculated in syngeneic mice are rejected if IL2 secreting allo- or xenogeneic cells are co-injected with tumour cells. We report here the large increase of ECT therapeutical efficacy when allogeneic cells secreting IL2 are injected into the peri-tumoural oedema.
