Table 1 Examples of Preclinical Activity in Rodents Treated with Autologous Cancer Vaccines: Effect of Tumor Burden on Outcome<br />

(Continued )<br />

Cancer type Vaccine type Efficacy Disease settings<br />

Preclinical Models and Clinical Situation 35<br />

Early: treatment started 1 day after tumor<br />

challenge<br />

Moderately advanced: treatment started 7 days<br />

after tumor challenge<br />

Advanced: treatment started 14 days after tumor<br />

100% complete tumor rejection (cure) in early<br />

setting vs. 60% cure in moderately advanced<br />

disease setting and 30% cure in advanced<br />

disease setting (14)<br />

Breast IL-2–transduced tumor<br />

cells<br />

challenge<br />

Early: treatment started 6 days after tumor<br />

challenge<br />

Advanced: treatment started 9 days after tumor<br />

challenge<br />

Minimal disease: primary tumor surgically<br />

removed prior to start of vaccination, yet still<br />

bore second tumor at distal site<br />

Bulky disease: no surgical resection and thus<br />

bore primary and secondary tumor at time of<br />

vaccination<br />

Early: treatment started 3 days after tumor<br />

challenge<br />

Moderately advanced: treatment started 7–10<br />

days after tumor challenge<br />

Early: treatment started 3 days after tumor<br />

challenge<br />

Moderately advanced: treatment started 10 days<br />

after tumor challenge<br />

Advanced: treatment started 17 days after tumor<br />

challenge<br />

70% of mice alive at day 200 (end of study) in<br />

early setting compared with 0% in control<br />

group vs. 20% alive in advanced disease (15)<br />

Kidney IL-4–transduced tumor<br />

cells<br />

Significant reduction in rate of tumor growth in<br />

minimal disease setting vs. no effect of<br />

vaccination in bulky disease setting (16)<br />

Mesothelioma B7-1–transduced tumor<br />

cells<br />

87% complete tumor rejection (cure) in early<br />

setting vs. 0% cure in moderately advanced<br />

disease setting (17)<br />

Myeloma TNF-a–transduced and<br />

B7-1–transduced tumor<br />

cells<br />

83% of mice alive at day 71 (end of study) in<br />

early setting, 34% alive in moderately<br />

advanced disease setting, and 0% alive in<br />

advanced disease setting (18)<br />

Fibrosarcoma IFN-g–transduced and<br />

B7-1–transduced tumor<br />

cells<br />
