Figure 2From: CXCR4 expression on circulating pan-cytokeratin positive cells is associated with survival in patients with advanced non-small cell lung cancer Circulating pan-cytokeratin positive cells and CXCR4/pan-cytokeratin positive cells in 16 patients with NSCLC and 10 normal subjects. CXCR4 and pan-cytokeratin were measured by FACS from normal healthy donors or patients with NSCLC (*p = 0.11, **p = 0.02). Horizontal line represents mean.Back to article page
