Fig. 2From: Prognostic factors for relapse-free survival in stage IB-IIIA primary lung adenocarcinoma by epidermal growth factor receptor mutation statusThe cumulative incidence of intrathoracic metastasis, distant metastasis, and metastasis to the central nervous system (CNS) was significantly higher in Mt high-risk patients than in Mt low-risk patients (a, c, e). The cumulative incidence of intrathoracic and distant metastases was higher in Wt high-risk patients than in Wt low-risk patients (b, d). The cumulative incidence of CNS metastasis tended to be higher in Wt high-risk patients than in Wt low-risk patients (f)Back to article page
