The Kaplan-Meier survival curves of nomogram for predicting CSS in SCLC patients with BM. (A) The cutoff values of risk score were determined by X-tile software, patients were divided into low-risk group (green): risk score <0.8, medium-risk group (grey): risk score 0.8–1.8 and high-risk group (red): risk score >1.8; (B) survival curves of high-risk, medium-risk and low-risk groups in the whole cohort; (C) survival curves of high-risk, medium-risk and low-risk groups in the training cohort; (D) survival curves of high-risk, medium-risk and low-risk groups in the validation cohort. SCLC, small cell lung cancer; BM, brain metastasis; CSS, cancer-specific survival.
