The serum B7-H3, B7-H1, cancer-associated carbohydrate antigen-50 (CA-50) and carcinoembryonic antigen (CEA) expressions in patients with CRC, benign gastrointestinal diseases, and healthy controls were measured by ELISA.
Multivariate analysis of PC revealed that T4 cancer (OR 5.143, 95% CI 1.400-18.897, p = 0.014), T3 mucinous cancer (OR 17.480, 95% CI 1.577-193.714, p = 0.020), obstructed tumors (OR 6.030, 95% CI 1.627-22.343, p = 0.007), and peritoneal fluid CEA above 5 ng/dl (OR 4.073, 95% CI 1.315-12.615, p = 0.015) were significant risk factors.
Generally, serum CEA levels have not been used as tumor markers for salivary gland malignancies; however, it may be useful for MAC arising from salivary glands.
Alpha-fetoprotein (AFP), cancer antigens 15.3, 19.9, and 125, carcinoembryonic antigen, and alkaline phosphatase (ALP) are widely measured in attempts to detect cancer and to monitor treatment response.
Patients age, a family history of cancer in a first-degree relative, pre-treatment levels of carcinoembryonic antigen (CEA), prognostic nutritional index (PNI), histological tumor grade, tumor-node-metastasis (TNM) stage, and LVI were independent prognostic indicators (all P<0.05).
In addition, the types and amount distribution of cancer in cancer group were also matched with somatic cancer-related CVST group patients.Compared to cancer group patients, somatic cancer-related CVST group patients had more intracranial metastasis, a higher platelet count, higher plasma D-dimer, carcinoembryonic antigen (CEA) and cancer antigen (CA) 125 levels, a greater platelet to lymphocyte ratio (PLR), and a greater platelet to neutrophil ratio (PNR).
KEY POINTS: The case exemplifies clinical benefit from sequential immune checkpoint blockade in a patient with Lynch syndrome with advanced metastatic colorectal cancer and urothelial cancer.Metabolic response, with decreased fluorodeoxyglucose avidity on positron emission tomography and computed tomography, and reductions in tumor markers, such as carcinoembryonic antigen, were helpful in this case to monitor disease status over a 28-month period of therapy.The concept of sequential immune checkpoint blockade in patients with advanced mismatch repair-deficient cancer merits further study to determine which patients are most likely to benefit.
By using of the sandwich-type immunoreactions and luminol-H<sub>2</sub>O<sub>2</sub>p-iodophenol (PIP) chemiluminescence(CL) system, three cancer biomarkers were simultaneously detected in human serum samples on μPADs with the linear range of 0.05-80.0 ng·mL<sup>-1</sup> for carcinoembryonic antigen (CEA), 5.0-80.0 ng·mL<sup>-1</sup> for alpha-fetal protein (AFP) and 1.0-50.0 ng·mL<sup>-1</sup> for prostate-specific antigen (PSA).
Three factors were significantly related to malignancy in IPMN; the diameter of the main pancreatic duct, the serum value of carcinoembryonic antigen (CEA), and the neutrophil-to-lymphocyte ratio (NLR).
Predictive significance of CYFRA21-1, squamous cell carcinoma antigen and carcinoembryonic antigen for lymph node metastasis in patients with esophageal squamous cancer.
Some CEACAMs such as CEACAM1, CEACAM5 and CEACAM6 are highly associated with cancer and are even recognised as valid clinical markers for certain cancer forms.
Levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and CA-125 in blood are used as markers to determine response of patients with cancer to therapy, but are not used to identify patients with pancreatic cancer.
This case report describes a rare underlying cause of hematoma after CEA, which reminds us to pay attention to prostate symptoms or related medical history, especially malignancy, in surgical patients, which may result in severe complications.
This biosensing approach demonstrates good reproducibility and high specificity for CEA in real serum samples providing a promising method to evaluate CEA in human serum for early diagnosis and monitoring of cancer.
These results clearly demonstrate a newly developed highly efficient and label-free impedimetric immunosensor for the detection of CEA using N, S-GQDs@Au-PANI nanowires as the biosensing probe, which can pave the gateway for the fabrication of high performance and robust impedimetric immunosensor to detect cancer makers in early stage of cancer diagnosis and therapy.
Abnormal Golgi pH Homeostasis in Cancer Cells Impairs Apical Targeting of Carcinoembryonic Antigen by Inhibiting Its Glycosyl-Phosphatidylinositol Anchor-Mediated Association with Lipid Rafts.
After excluding patients with missing data for at least one malignancy predictor in the nomogram (main pancreatic duct diameter, cyst size, presence of mural nodule, serum carcinoembryonic antigen and carbohydrate antigen (CA) 19-9 levels, and age).
All asymptomatic individuals underwent screening investigations for malignancy including PAP smear, mammography, low-dose computed tomography, evaluation of cancer antigen 125, cancer antigen 19-9, alpha fetoprotein, carcinoembryonic antigen, prostate specific antigen (PSA) levels and clinical examination to identify healthy individuals with no indication of cancer.
At current work, the combination of sensors were used to detect the presence of BCR-ABL1 as a mutant gene and CEA as a biomarkers of cancer, such a capability makes the package liable for early and certain detection of acute lymphoblastic leukemia.
