Key result
Apolipoprotein A2 isoform index improves pancreatic cancer detection when added to CA19-9.
Why the study?
Does the apoA2-i index improve diagnostic performance for pancreatic cancer?
Does the apoA2-i index improve diagnostic performance for pancreatic cancer?
The apoA2-i index may be a useful adjunctive tumor marker for detecting pancreatic cancer, particularly in CA19-9-negative cases.
The apoA2-i index can detect CA19-9-negative pancreatic cancer, and the combination of the apoA2-i index with CA19-9 enhances diagnostic performance in clinical practice.
