Prognostic value of carcinoembryonic antigen and carbohydrate antigen 19–9 in periampullary cancer patients receiving pancreaticoduodenectomy

Asian Journal of Surgery, 2021
Background: We assessed the use of serum concentrations of carbohydrate antigen (CA) 19–9 and carcinoembryonic antigen (CEA) measured during the preoperative diagnostic workup as prognostic factors for survival in patients with periampullary carcinoma ...

Decreased serum carbohydrate antigen 19–9 levels after neoadjuvant therapy predict a better prognosis for patients with pancreatic adenocarcinoma: a multicenter case-control study of 240 patients

BMC Cancer, 2019
Background Carbohydrate antigen (CA) 19–9 levels after resection are considered to predict prognosis; however, the significance of decreased CA19–9 levels after neoadjuvant therapy has not been clarified.

Clinical characteristics and outcomes in carbohydrate antigen 19-9 negative pancreatic cancer. [PDF]

World J Clin Oncol, 2022
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of death from cancer worldwide. Tumor markers like carbohydrate antigen 19-9 (CA 19-9) have been proven valuable as a diagnostic tool and a predictor for tumor staging and response to ...

Novel tumor marker index using carcinoembryonic antigen and carbohydrate antigen 19-9 is a significant prognostic factor for resectable colorectal cancer. [PDF]

Sci Rep
We evaluated the usefulness of a newly devised tumor marker index (TMI), namely, the geometric mean of normalized carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), in determining colorectal cancer (CRC) prognosis.
