Use of cyst fluid CEA, CA19-9, and amylase for evaluation of pancreatic lesions
Abstract
Objectives: The study goals were development of reference intervals and an interpretive algorithm for pancreatic cyst fluid tumor markers.
Design and methods: 442 pancreatic cyst fluids were tested for CEA, CA19-9, and amylase.
Results: CEA>30 ng/mL discriminates mucinous from non-mucinous cysts. After CEA analysis, amylase and CA19-9 segregate non-mucinous and mucinous subtypes, respectively.
Conclusions: Pancreatic cyst fluid tumor markers supplement other diagnostic measures. This study provides estimated reference intervals and an algorithm for interpretation.
