ca19-9 یک آنتی ژن کربوهیدراتی است که کاربردش به طور شایع به عنوان نشانگر سرمی تومور در بدخیمی های پانکراس و مجاری صفراوی افزایش می یابد. حساسیت ca19-9 در تشخیص بدخیمی پانکراس،70 تا 90 درصد و وی‍ژگی، 68 تا 91 درصد می باشد. افزایش ca19-9 در موارد دیگری از جمله سایر بدخیمی ها و برخی وضعیت های خوش خیم مانند انسداد مجاری صفراوی، به علل دیگر از جمله سنگ نیز دیده می شود اما در این موارد افزایش، قابل ت...
BACKGROUND A phase I/II study and subsequent phase III study (MPACT) reported significant correlations between CA19-9 decreases and prolonged overall survival (OS) with nab-paclitaxel plus gemcitabine (nab-P + Gem) treatment for metastatic pancreatic cancer (MPC). CA19-9 changes at week 8 and potential associations with efficacy were investigated as part of an exploratory analysis in the MPACT ...
BACKGROUND Measurement of objective response to chemotherapy using imaging modalities is sometimes difficult in pancreatic cancer (PC). We aimed to verify whether monitoring of serum tumor markers (TMs), namely carcinoembryonic antigen, CA19-9, DUPAN-2, SPan-1, can facilitate earlier confirmation of treatment failure. METHODS Monitoring of serum TMs and computed tomography were performed ever...
PURPOSE Biomarkers for the early detection of pancreatic cancer are urgently needed. The primary objective of this study was to evaluate whether increased levels of serum CA19-9, CA125, CEACAM1, and REG3A are present before clinical presentation of pancreatic cancer and to assess the performance of combined markers for early detection and prognosis. EXPERIMENTAL DESIGN This nested case-contro...
Background: Aims serum markers provide a non-invasive, cheap and effective diagnostic and prognostic tool for cholangiocarcinoma. In this study, we aimed to evaluate serum levels of CEA, CA125, CA19-9 and CA724 for the diagnosis and staging of cholangiocarcinoma. Materials and methods: Serum levels of CA125, CA19-9, CA724 and CEA were measured preoperatively, postoperatively and during follow-u...
Here we report the first case of carbohydrate antigen (CA) 19-9-producing early gastric adenocarcinoma arising in polyp. A solitary pedunculated polyp lesion of the stomach, measuring 26 × 20 × 20 mm, was noticed in a 76-year-old Japanese woman due to an abdominal disorder, associated with a markedly high serum CA19-9 level (2,172.6 U/ml). After endoscopic mucosal resection was performed, the C...
BACKGROUND Free tumour cells in the peritoneal cavity of patients with pancreatic carcinoma carry a poor prognosis. Reactive or degenerative mesothelial cells can make cytological interpretation with conventional stains difficult. Detection of the tumour-associated antigens carcinoembryonic antigen (CEA) and CA19-9 may improve detection. METHODS At staging laparoscopy, 22 patients with pancre...
We assessed the prognostic significance of preoperative serum carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 242 (CA242) levels in surgically treated colorectal cancer patients. The relationship of preoperative serum CEA, CA19-9 and CA242 levels with disease characteristics was investigated in 310 patients. Correlation between tumor markers was inves...
E-selectin, expressed on endothelial cells, mediates adhesion of leukocytes and tumor cells to endothelium. CA19-9 (sialyl-Lewis(a)) and sialyl-Lewis(x) are specific ligands for E-selectin. We have recently shown that mucin-rich culture media from human gallbladder epithelial cells contains CA19-9. In this study, we have tested whether human biliary mucin binds to E-selectin. The ability of muc...
Objective: We had previously demonstrated that the carbohydrate antigen 19-9 (CA19-9), lactate dehydrogenase (LDH), neutrophil lymphocyte ratio (NLR) are prognostic factors for patients with metastatic colorectal cancer (mCRC). In this study, we try to analysis the association of these blood-based biomarkers with bevacizumab efficacy in the first line setting. Methods: A total of 284 eligible c...
