Kaplan-Meier curves with log-rank test comparing recurrent free survival (RFS) in different subgroups (A) Bladder cancer patients with low SAM68 expression (bold line) had a cumulative 5-year RFS rate of 80.0%, compared to 52.9% for patients with high SAM68 expression (dotted line; p = 0.001). (B) Comparison of RFS curves between groups with different SAM68 intracellular localization. The RFS curves were similar between SAM68 nucleus expression and cytoplasm expression groups (p = 0.539). However, the RFS was much worse in the nucleus-cytoplasm co-expression group, no matter compared with nucleus expression group (p = 0.002) or cytoplasm expression group (p = 0.037).
