Kaplan-Meier analysis for progression-free survival (PFS) in 57 SOEC patients treated with taxane-based chemotherapy. Positive expression of Class III β-tubulin (a), Sox2 (b), and only nuclear Survivin (c) was associated with poor PFS (p = 0.032, 0.005, and 0.004, respectively). Expression of only cytoplasmic Survivin (d) was not related to PFS (p = 0.727). Number of patients at risk at the beginning of each year is shown below the horizontal axis
