FUT3 and pancreatic neoplasm: A recent study found that the accuracy of early pancreatic cancer blood tests (CA19-9 and DUPAN-2) was improved when monitored by measuring the FUT2/FUT3 genotype subgroups and combining CA199 with DUPAN-2.183 Therefore, the detection of FUT added to patients with low CA19-9 expression may contribute to a more effective diagnosis of pancreatic cancer.
