Overall survival analysis for CXCR4 cytoplasmic expression. Kaplan-Meier curves for overall survival (OS) in 110 patients with high expression of CXCR4 and 90 patients with low expression of CXCR4 in cytoplasm. Survival time sharply decreased in patients with high CXCR4 cytoplasmic expression, especially in the first five years, Meanwhile, survival of patients with low CXCR4 expression was merely moderately affected (P = 0.011).
