CA15-3 (Cancer Antigen 15-3) is a tumor marker used to monitor certain cancers, especially breast cancer. It is found on the surface of many types of cancer cells and shed into the blood stream. It is used to monitor advanced, i.e. metastatic, cancer.[1]
Elevated CA15-3, in conjunction with alkaline phosphatase (ALP), was found to be associated with an increased chance of early recurrence in breast cancer.[2]
CA15-3 and associated CA27.29 (aka BR27.29) are different epitopes on the same protein antigen product of the breast cancer-associated MUC1 gene. CA27.29 has enhanced sensitivity and specificity and has therefore surpassed CA15-3 as a serum tumor marker. CA27.29 is elevated in 30% of patients with low-stage disease and 60 to 70% of patients with advanced-stage breast cancer.
Both CA27.29 and CA15-3 may be elevated in patients with benign ovarian cysts, benign breast disease, and benign liver disease. Elevations may also be seen in cirrhosis, sarcoidosis and lupus.
CA27.29 levels over 100 U/mL or CA15-3 levels over 25 U/mL are rare in benign conditions.
CA27.29 may be elevated in non-breast malignancies including colon, stomach, pancreas, prostate and lung.

- Novel electrochemical aptamer biosensor based on an enzyme-gold nanoparticle dual label for the ultrasensitive detection of epithelial tumour marker MUC1.
- Hu R, Wen W, Wang Q, Xiong H, Zhang X, Gu H, Wang S.Author information Hubei Collaborative Innovation Center for Advanced Organic Chemical Materials, Ministry of Education Key Laboratory for the Synthesis and Application of Organic Functional Molecules & College of Chemistry and Chemical Engineering, Hubei University, Wuhan 430062, PR China.AbstractA novel platform based on a hairpin oligonucleotide (HO) switch, gold nanoparticles (AuNPs), and enzyme signal amplification for the ultrasensitive detection of mucin 1 protein (MUC1) was developed in this assay. This HO aptamers and horseradish peroxidase (HRP) were immobilised on the AuNPs to yield HO-AuNP-HRP conjugates. AuNPs were used as labels and bridges between the HO and HRP. HRP was also used as label for catalysing the oxidation of o-phenylenediamine by H2O2. The reaction product was 2,3-diaminophenazine (DAP), which was reduced and could be detected at surface of modified electrode. The reduction signal of DAP was used as a probe for the sensitive detection. After the recognition between oligonucleotide and MUC1, biotin was exposed. Biotin, along with the conjugate, was captured by streptavidin onto the surface of modified electrode. Therefore, the detection of target MUC1 which was a membrane-associated glycoprotein of the mucin family could be sensitively transduced via detection of the electrochemical reduction signal of DAP. Compared to other aptasensors, this biosensor has a good linear correlation ranges from 8.8nM to 353.3nM and a lower detection limit of 2.2nM for MUC1. The proposed method provided a new electrochemical approach for the detection of MUC1.

Electronic address: hezhy@sysucc.org.cn.AbstractThe prognostic significance of preoperative carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) levels in breast cancer is controversial. This study evaluated the prognostic value of preoperative serum CEA and CA15-3 levels in Chinese breast cancer patients. A total of 470 patients with breast cancer had preoperative CEA and CA15-3 concentrations measured. The relationships between preoperative concentration and clinicopathological factors and outcomes were determined. CEA and CA15-3 levels were increased in 34 (7.2%) and 58 (12.3%) patients, respectively. Elevations of serum CEA and CA-15-3 levels correlated with the primary tumor size and axillary lymph node status. CEA levels were lower in patients with triple-negative breast cancer than in those with other subtypes (P = 0.002). The 5-year distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) of CEA-negative vs. CEA-positive patients were 84.1% vs. 54.5% (P < 0.001), 82.7% vs. 54.8% (P < 0.001), and 89.7% vs. 78.5% (P = 0.007), respectively. The 5-year DMFS, DFS, and OS of CA15-3-negative vs. CA15-3-positive patients were 84.0% vs. 69.6% (P = 0.002), 83.0% vs. 66.2% (P < 0.001), 90.9% vs. 74.2% (P = 0.005), respectively. Multivariate analysis of prognosis indicated that CEA and CA15-3 levels were independent prognostic factors for DMFS (P = 0.021) and DFS (P = 0.032), and DFS (P = 0.014) and OS (P = 0.032), respectively. Serum levels of CEA and CA15-3 may differ in breast cancer molecular subtypes and preoperative levels of CEA and CA15-3 have a significant effect on prognosis in Chinese women with breast cancer.

- Gold nanoparticle modified capacitive sensor platform for multiple marker detection.
- Altintas Z, Kallempudi SS, Gurbuz Y.Author information Faculty of Engineering and Natural Science, Sabanci University, Orhanli, Tuzla, Istanbul 34956, Turkey.AbstractThe detection and quantification of cancer biomarkers in human blood is crucial to diagnose patients in the early stage of a disease. The recent advances in biosensor technology can improve detection by reducing the application time and cost without an invasive approach. In this study, a highly sensitive, novel nanoparticle-modified capacitive sensor was developed for the detection of cancer markers. The current work mainly focused on developing a surface modification protocol for achieving higher sensitivity using Au-NPs. An interdigitated electrode (IDE) transducer was modified using gold nanoparticles (Au-NPs) for signal enhancement, the platform was initially optimized with a small size IL-6 protein and the methodology was then applied for multiple marker detection with the aim of precise disease diagnostics. Carcinoembryonic antigen (CEA) and epidermal growth factor receptor (hEGFR) could be successfully detected in the concentration range of 20-1000pgmL(-1) while cancer antigen 15-3 (CA15-3) was detected in the range of 10-200UmL(-1). These results show an increase of sensitivity by five-fold with respect to those not modified, demonstrating a highly sensitive and specific capacitive immunoassay that has a great potential for the use of early diagnosis of cancer disease.
