Circulating tumor cells detected by lab-on-a-disc: Role in early diagnosis of gastric cancer
Fig 3
Receiver operating characteristic (ROC) curve.
The value of circulating tumor cells (CTCs) showed an area under the ROC curve of 0.928 (95% confidence interval: 0.885–0.971, P < 0.001). To identify the optimal CTC threshold value for differentiating patients with gastric cancer from healthy controls, the sensitivity and specificity were optimized using a threshold count of 2 CTCs per 7.5 mL of blood.
