2. Fig. 1
Heatmap representing the expression profiles of the 23 genes across the nonrecurrent (NR) group (n=21) and the recurrent (R) group (n=23). The genes have been ordered according to descending Mann-Whitney U p values, with the genes above the white horizontal margin being statistically significantly different (p<0.05). Expression levels: Red and blue indicate higher and lower expression relative to the median (black), respectively.

3. Fig. 2
Distribution of survivin expression in the nonrecurrent (NR) group and the recurrent (R) group. The boxes represent the survivin expression interquartile range. Open triangles represent outliers. The median survivin expression level (black horizontal bar) in the NR group and the R group are (range in parenthesis), respectively, 0.22 (0.0025–4.35) and 1.96 (0.25–7.31). The difference between the two groups is statistically significant (p=0.0011).

The performance of survivin for the identification of patients with short or prolonged recurrence-free periods. Comparison of the receiver operating characteristic curves for survivin expression between patients with long or short recurrence-free periods revealed an area under the curve of 0.79 (95%CI, 0.65–0.92).
