Figure 6

Risk stratification based on EFS and OS correlates with serum Shh and IL-6 levels in metastatic breast cancer. (A) Event free survival (EFS) of all progressive metastatic patients by serum Shh levels, (B) EFS of all progressive metastatic patients based on serum IL-6 levels, (C) EFS of all progressive metastatic patients based on a two-factor model (serum Shh and IL-6). (D) Overall survival (OS) of all progressive metastatic patients based on a two-factor model (serum Shh and IL-6). Note worse overall outcome for patients with both Shh and IL-6 at a high level.
