CA19-9 for detecting recurrence of pancreatic cancer [PDF]

Scientific Reports, 2020
AbstractCA19-9 values are regularly measured in patients with pancreatic cancer. Certainly, its potential as a biomarker has been compromised by false negative results in CA19-9 negative patients and false positive results in benign pancreatico-biliary diseases. For detection of PDAC recurrence, however, CA19-9 might play an important role.

Prognostic significance of carbohydrate antigen 19-9 (CA19-9) change during immediate postoperative periods in patients with stage I–III colorectal cancer [PDF]

Annals of Coloproctology
Purpose Although carbohydrate antigen 19-9 (CA19-9) may exhibit low sensitivity in tumor screening, its prognostic significance has been highlighted. This study assessed the significance of preoperative CA19-9 and early postoperative CA19-9 levels in ...

CA19-9/DBil: a promising indicator to distinguish between CA19-9-elevated pancreatic head-type autoimmune pancreatitis and pancreatic head cancer [PDF]

BMC Gastroenterology
Background Pancreatic head-type autoimmune pancreatitis (PH-AIP) with elevated CA19-9 is sometimes difficult to distinguish from pancreatic head cancer (PHC) with elevated CA19-9. At times, IgG4 proves inadequate in offering assistance.
