Optical immunosensor panel using quantum dot-antibody conjugates for highly sensitive detection of carbohydrate antigen 19–9 (CA19-9)

Analytica Chimica Acta
This study introduces a fluorescent immunosensor colour panel with antibody-conjugated quantum dots for detecting CA19-9 in human serum. The immunosensors presented decreasing fluorescence with increasing CA19-9 concentrations, with a linear detection range from 0.01 to 501.87 U mL-1 and detection limits of 1.66 × 10⁻⁴, 2.71 × 10⁻⁴, and 5.45 × 10⁻⁴ U ...

The Efficacy of Serum Carcinoembryonic Antigen (CEA), Cancer Antigen 125 (CA125), Carbohydrate Antigen 19-9 (CA19-9), Carbohydrate Antigen 15-3 (CA15-3), α-Fetoprotein (AFP) and Human Chorionic Gonadotropin (hCG) Levels in Determining the Malignancy of Solitary Pulmonary Nodules

Journal of International Medical Research, 2009
We investigated the utility of the tumour markers carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3), α-fetoprotein (AFP) and human chorionic gonadotropin (hCG) for the differential diagnosis of benign and malignant solitary pulmonary nodules in 42 hospitalized patients ...

Developing a Prognostic Model for Intrahepatic Cholangiocarcinoma Patients With Elevated Preoperative Carbohydrate Antigen 19-9 Levels: Volume-Adjusted CA19-9 (VACA) as a Novel Biomarker

Cancer Control
Purpose The predictive sensitivity of carbohydrate antigen 19-9 (CA19-9) in assessing the prognosis of intrahepatic cholangiocarcinoma (ICC) remains inadequate. Integrating CA19-9 with tumor volume offers a potentially viable strategy for improving prognostic accuracy.

Diagnostic and Prognostic Value of CEA and CA19-9 in Colorectal Cancer

Diseases, 2021
Colorectal cancer (CRC) is the third most common cancer worldwide. A diagnosis at early stages with enhanced screening methods is vital as metastases and recurrences increase mortality.

Increased carbohydrate antigen 19‐9 expression in a thymic neuroendocrine tumor

Thoracic Cancer, 2021
Here, we report a case of carbohydrate antigen (CA) 19‐9‐producing mediastinal neuroendocrine tumor (NET) (atypical carcinoid). A 54‐year‐old woman with no specific relevant medical history was referred to our hospital because of increased CA19‐9 (95.3 U/

Metastatc Gastric Adenocarcinoma Cancer With a Very High Serum Carbohydrate Antgen 19-9 Level: A Case Study

Case Reports in Clinical Practice, 2021
Carbohydrate Antigen 19-9 (CA19-9) is a tumor marker for the prognosis of colorectal and pancreatic cancers. The high level of this tumor marker in gastric cancer indicates the advanced stage and peritoneal metastasis of the tumor.
