EPCAM and pancreatic neoplasm: Researchers using an EpCAM-independent enrichment method—Isolation by Size of Tumour cells (ISET®)41, 43—have reported considerably higher amounts of CTCs in pancreatic cancer patients, with CTC detection in 93% (mean: 26 CTCs/7.5 mL peripheral blood, range: 0–240)41 and 78% (mean: 18 CTCs/mL peripheral blood, range: 0–251)43 of patients.
