Kaplan-Meier survival plot.

<p>Survival of the different experimental groups based on euthanasia timepoints resulting from excessive tumor burden, when tumors reached 18 mm in any given dimension. The total experimental period was 34 days post-IRE treatment. Where 70% of the treated immunocompetent (IC) BALB/c mice survived until the endpoint of the study, nearly all control IC mice and both experimental immunodeficient (ID) nude mice groups were euthanized prior to reaching the endpoint due to excessive tumor burden.
