Figure 3From: Prognostic impact of detecting viable circulating tumour cells in gastric cancer patients using a telomerase-specific viral agent: a prospective study Comparison of cell diameter between patients and volunteers. To determine the threshold, we compared the diameters of cells from gastric cancer patients and controls by ROC analysis. There was a significant difference between the gastric cancer patients and the controls (p < 0.001; area under the curve = 0.57; 95% confidence interval = 0.54–0.60).Back to article page
