Figure 10. Metastatic growth under different values of Inline graphic.

Figure 10

The primary tumor is held to a steady state by the immune response, and metastases are seeded beginning 6 months into the simulation. For the lowest value of Inline graphic, a single metastatic lesion forms; moderate to high values lead to suppression of all metastases, while a very high Inline graphic overwhelms the immune response, leading to widespread metastatic growth. Note that in (C) and (D) the immune response to the metastases can cause perturbations in the primary tumor size, but does not change the overall behavior. (A) Inline graphic. (B) Inline graphic.
