Survival of TS/A tumor‐bearing BALB/c mice. Tumor therapy was performed as detailed in Materials and Methods. Four groups of five mice bearing established subcutaneous TS/A tumors were treated 7 days after tumor implantation with DC + CpG 15/10, CpG 15/10 alone, DCs alone, or PBS given twice, 7 days apart, by subcutaneous injection in the flank opposite the tumor nodule. Data are represented as % survival at 240 days after initial tumor implantation, p values presented with respect to DC + CpG 15/10 using the log‐rank test.
