Abstract
Objective: This study was designed and conducted to establish the relationship of biomarker CA19-9 levels in pancreaticobiliary and gastrointestinal malignancies. Methods: 50 patients with confirmed diagnosis of pancreaticobiliary and gastrointestinal malignancies and 30 age and gender matched controls were included in the study. Serum values of CA19-9 were determined in patients before surgery and chemotherapy. Results: In our present study, maximum number of patients were in the age group of 51–60 years. Mean levels of serum CA19-9 in patients (n=50) are 146.28±156.87 U/mL. Total patients (n=50), in 19 patients CA19-9 levels were ≤37 U/mL and in 31 patients CA19-9 levels were >37 U/mL. CA19-9 levels were highest in pancreatic and cholangiocarcinoma. Conclusion: High sensitivity and specificity of CA19-9 in pancreatic and biliary tract tumors identified CA19-9 as a best validated biomarker.
