CTC count in pancreatic cancer patients and healthy controls. a, Distribution of CTCs in diagnosed pancreatic cancer and health controls, existence of CTCs in 25 pancreatic cancer patients and 20 healthy controls were examined. b Distribution of CTCs in patients with pancreatic cancer according to pathological staging (TNM). c Comparison of circulating tumor cells and CA19-9 as blood-based markers. The blue horizontal dashed line indicated the CA 19-9 threshold of 37 U/ml. d ROC curves for CTCs count to discriminate pancreatic cancer patients from healthy controls. The cutoff value was defined as 2 CTCs/7.5 ml
