Expression of PinX1 in breast cancer tissues and associated with 5-year overall and disease-specific survival in breast cancer patients. (A) Negative and positive staining in breast cancer tissue. Top panel, magnification × 200; bottom panel, magnification × 400. (B) Low PinX1 expression correlated with a poorer 5-year overall cumulative survival for 236 breast cancer patients (P = 0.010, log-rank test). (C) Low PinX1 expression correlated with a poorer 5-year disease-specific cumulative survival for 208 breast cancer patients (P = 0.003, log-rank test). Cum. indicates cumulative.
