GLI1 and neoplasm: Comparison of the Kaplan Meier curves of recurrence-free survival showed a significantly more rapid rate of tumor recurrence in patients with tumors expressing high levels of GLI1 (HR = 2.63; 95% CI: 1.0, 6.5; P = 0.04; Median recurrence-free survival was 30 months in the High GLI1 group vs. 85 months in the Low GLI1 group; Figure 2B).
