Survival rate of mice that received a single injection or multiple injections of HVJ-E/BLM. The mice were injected with HVJ-E/BLM on day 1 or days 1, 6, and 9 after CDDP treatment (i.p.) on day 0. Control mice had no treatment after CT-26 tumor injection. Results are representative of two independent experiments. Results were statistically analyzed using Kaplan-Meier method and log-lank test (n = 5).
