Association of CYP19A1 mRNA expression with the survival of human breast cancer patients. Kaplan-Meier analyses of the overall survival (a, d, g), disease-free survival (b, e, h) and metastasis-free survival (c, f, i) in unselected patients (a–c; n = 100), ER-positive patients (d–f; n = 40), and ER-negative patients (g–i; n = 56) are shown. Patient subgroups with high and low CYP19A1 expression and their numbers (n) are indicated in each panel. ER, estrogen receptor
