Tumor growth and survival rate in the lung metastasis model. A. Series of CT scan images showing development of the lung metastases, (a, b): a control mouse, (c, d): a Tpit/E vaccinated mouse; day 14 (a, c) and 21 (b, d) after tumor challenge. Tumors were indicated by arrowheads. No lung metastasis was observed in panel c. B. Survival rate after tumor challenge, p < 0.05: Tpit/E vaccine vs. control.
