Fig. 1From: Multiple antigen-engineered DC vaccines with or without IFNα to promote antitumor immunity in melanomaKaplan-Meier plot of OS and PFS. a and b. OS and PFS is shown for patients who were randomized after DC vaccines (n = 23) to observation (no boost, n = 12 randomized + 2 not receiving HDI) or those randomized to HDI (n = 11 randomized, 9 receiving IFN). OS: IFN vs. OBS p = 0.54 (ns). PFS: IFN vs. OBS p = 0.43 (ns). Not shown are those who progressed early, before randomization (n = 12), who were the statistically significant different clinical group vs. those randomized (OS p = 0.0001, PFS p < 0.0001)Back to article page
