Figure 1From: Membrane-bound estrogen receptor-α expression and epidermal growth factor receptor mutation are associated with a poor prognosis in lung adenocarcinoma patientsA. Kaplan-Meier curve for recurrence-free survival according to the presence or absence of membrane-bound ERα expression. The RFS tended to be worse in patients showing elevated mERα expression level in the tumor cells than that of the patients not showing tumor-cell mERα expression (P = 0.076, log-rank test). B. The RFS of the patients in the double-positive group was significantly worse than that of the other patients (P = 0.003, log-rank test).Back to article page
