  • Title: Use of cyst fluid CEA, CA19-9, and amylase for evaluation of pancreatic lesions.
    Author: Snozek CL, Mascarenhas RC, O'Kane DJ.
    Journal: Clin Biochem; 2009 Oct; 42(15):1585-8. PubMed ID: 19576876.
    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.
