The incidence rate of esophagogastric junction (EGJ) adenocarcinoma has been rapidly increasing worldwide. Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are major serum tumor markers in gastrointestinal cancers. However, the role of these markers in EGJ adenocarcinoma has not been thoroughly investigated. A total of 211 patients with EGJ adenocarcinoma who underwent surg...
BACKGROUND The present study was undertaken to establish any correlation of elevated levels of CA19-9 with tumor stage or grade of urothelial carcinoma. MATERIALS AND METHODS This hospital based study was carried out in the Department of Biochemistry of Nepalese Army Institute of Health Sciences between 1st July 2012 and 31st December 2012. Approval for the study was obtained from the institu...
Although carbohydrate antigen (CA19-9) level is frequently upregulated in pancreatobiliary cancer, it is also elevated in some benign diseases. This study aimed to determine whether CA19-9 levels could be used to distinguish between benign obstructive jaundice and pancreatobiliary cancer. Fifty-seven patients with obstructive jaundice were studied retrospectively. Endoscopic retrograde cholangi...
CA19-9 is a tumor-associated antigen. It is also a marker of pancreatic tissue damage that might be caused by diabetes. Long-term poor glycemic control may lead to pancreatic beta cell dysfunction which is reflected by elevated serum CA19-9 level. Intracellular cholesterol accumulation leads to islet dysfunction and impaired insulin secretion which provide a new lipotoxic model. This study firs...
OBJECTIVE The current study was designed to analyze the value of 18F-FDG positron emission tomography/computed tomography (PET/CT) combined with carbohydrate antigen 19-9 (CA19-9) in differentiating pancreatic carcinoma (PC) from chronic mass-forming pancreatitis (CMFP) in Chinese elderly. METHODS As it is impossible to differentially diagnose PC from CMFP, 60 participants older than 65 years...
BACKGROUND/AIM The performance of the circulating tumor markers carbohydrate antigen 19-9 (CA19-9), matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) were evaluated separately and in combination for their potential value in detecting pancreatic ductal adenocarcinoma. PATIENTS AND METHODS The patients had symptoms of pancreatic cancer. The discriminative s...
OBJECTIVE Hilar cholangiocarcinoma is the fourth most common gastrointestinal malignancy. CA19-9 and CEA are helpful devices in the management of gastrointestinal malignancies and belong to clinical routine in surgical oncology. But the validity of these parameters in terms of tumor extension and prognosis of bile duct malignancies still remains unclear. METHODS From 1998 to 2008, we obtained...
Carbohydrate antigen 19-9 (CA19-9) is a well-known tumor marker for pancreatobiliary cancer, and several studies have shown that an elevated serum CA19-9 level is associated with more aggressive biological behavior in gastric cancer (GC). However, the clinicopathological characteristics of CA19-9-positive GC remain unclear. We herein report an autopsy case of CA19-9-positive GC in an 84-year-ol...
Currently the diagnosis of pancreatic ductal adenocarcinoma (PDAC) relies on CA19-9 and radiological means, whereas some patients do not have elevated levels of CA19-9 secondary to pancreatic cancer. The purpose of this study was to identify potential serum biomarkers for CA19-9 negative PDAC.A total of 114 serum samples were collected from 3 groups: CA19-9 negative PDAC patients (n = 34), CA19...
PURPOSE To diagnose the urothelial carcinoma of the bladder by measuring CA19-9 level in the urine. MATERIALS AND METHODS This study was conducted on 47 patients with histopathologically confirmed urothelial cancer and 50 control subjects. The urinary level of CA19-9 was measured in both groups by enzyme-linked immunosorbent assay after concentration of urine with Bio-Gel dry beads. Urine cyt...
