Expression of Epithelial and Mesenchymal Markers in Plasmatic Extracellular Vesicles as a Diagnostic Tool for Neoplastic Processes. Int J Mol Sci 2023; 24:ijms24043578. [PMID: 36834987 PMCID: PMC9964693 DOI: 10.3390/ijms24043578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 02/03/2023] [Accepted: 02/07/2023] [Indexed: 02/12/2023] Open
Abstract
Tumor-derived extracellular vesicles (TD-EVs) have active roles as cancer hallmark enablers. EVs RNA of epithelial and stromal cells carry information that facilitates the communication processes that contribute to oncological progression, so the objective of this work was to validate by RT-PCR the presence of epithelial (KRT19; CEA) and stromal (COL1A2; COL11A1) markers in RNA of plasmatic EVs in healthy and diverse-malignancy patients for the development of a non-invasive cancer diagnosis system using liquid biopsy. Ten asymptomatic controls and 20 cancer patients were included in the study, and results showed that the isolated plasmatic EVs by scanning transmission electron microscopy (STEM) andBiomedical Research Institute A Coruña nanoparticle tracking analysis (NTA) contained most exosome structures with also a considerable percentage of microvesicles. No differences were found in concentration and size distribution between the two cohorts of patients, but significant gene expression in epithelial and mesenchymal markers between healthy donors and patients with active oncological disease was shown. Results of quantitative RT-PCR are solid and reliable for KRT19, COL1A2, and COL11A1, so the analysis of RNA extracted from TD-EVs could be a correct approach to develop a diagnostic tool in oncological processes.

Abstract
Inflammatory reactions play a crucial role in cancer progression and may contribute to systemic inflammation. In routine clinical practice, some inflammatory biomarkers can be utilized as valuable predictors for colorectal cancer (CRC). This study aims to determine the usefulness of a novel cancer-inflammation prognostic index (CIPI) marker derived from calculating carcinoembryonic antigen (CEA) multiplied by the neutrophil-to-lymphocyte ratio (NLR) values established for non-metastatic CRCs. Between January 1995 and December 2018, 12,092 patients were diagnosed with stage I to III primary CRC and had radical resection—they were all included in this study for further investigation. There were 5996 (49.6%) patients in the low-CIPI group and 6096 (50.4%) patients in the high-CIPI group according to the cutoff value of 8. For long-term outcomes, the high-CIPI group had a significantly higher incidence of recurrence (30.6% vs. 16.0%, p < 0.001) and worse relapse-free survival (RFS) and overall survival (OS) rates (p < 0.001). High CIPI was an independent prognostic factor for RFS and OS in univariate and multivariate analyses. This research is the first to document the independent significance of CIPI as a prognostic factor for CRC. To ensure that it works, this CIPI needs to be tested on more CRC prediction models.

Abstract
Thyroid cancer is the most important endocrine cancer with increasing
incidence. While thyroid cancers, especially papillary thyroid cancers, are known to
exhibit generally a favorable outcome with excellent survival rates, some thyroid
cancers are more aggressive with a poor prognosis. Several different biomarkers have
been introduced for the diagnosis of disease, identification of tumor load, assessment of
therapy response, and the detection of recurrence during follow-up of the thyroid
cancer patients. This chapter gives a brief overview of the circulating biomarkers used
in thyroid cancer patients.

Abstract
BACKGROUND Previous studies have evaluated the clinicopathological significance of carcinoembryonic antigen (CEA) of esophageal cancer in relatively small numbers of patients. Therefore, this study aimed to clarify the prognostic significance of CEA in 1822 patients with esophageal squamous cell carcinoma (SCC). METHODS Based on the Japanese Esophageal Society nationwide multi-institutional retrospective study, a total of 1,748 surgically treated ESCC from 15 hospitals were enrolled to evaluate prognostic impact of preoperative CEA values. Among them, 605 patients were categorized to up-front surgery group, and 1,217 patients were categorized to neoadjuvant therapy group. The CEA threshold for positivity was 3.7 ng/ml. The clinicopathological and prognostic impact of CEA was evaluated by univariate and multivariate analysis in each treatment modality groups. RESULTS In total, the CEA positive rate was 25.8% (470/1822). CEA-positive status was significantly associated with distant metastasis (P = 0.004) but not associated with other factors. CEA-positive status was associated with poor overall survival (P < 0.001) in univariate analysis as well as multivariate analysis (P = 0.003). CONCLUSIONS CEA was an independent prognostic determinant of overall survival in esophageal SCC. Based on the subgroup analysis, regardless of the treatment modality, patients with high pretreatment CEA showed poor overall survival.

Prognostic role of neoplastic markers in Takotsubo syndrome. Sci Rep 2021; 11:16548.

Abstract
Takotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

Abstract
This work addresses the fabrication of an efficient, novel, and economically viable immunosensing armamentarium that will detect the carcinoembryonic antigen (CEA) typically associated with solid tumors (sarcomas, carcinomas, and lymphomas) and is used as a clinical tumor marker for all these malignancies. We synthesized silver nanoparticles by single-step chemical reduction and coated with silica using a modified Stober method to fabricate silica-coated silver core-shell nanoparticles. The morphologies, structure, and size of the nanoparticles were characterized by Transmission Electron Microscopy (TEM), UV-Visible spectroscopy, X-ray diffraction (XRD), Raman spectroscopy, Fourier Transform Infra-Red Spectroscopy (FTIR), and Dynamic Light Scattering (DLS), respectively. The results indicated that the average size of Ag nanoparticles and silica-coated Ag nanoparticles is 50 nm and 80 nm, respectively. Our TEM results indicate that the silica-shell uniformly encapsulates silver core particles. Further, a disposable electrochemical immunosensor for carcinoembryonic antigen (CEA) was proposed based on the antigen immobilized in a silica-coated silver core-shell nanoparticle film on the surface of an indium-tin-oxide (ITO) flat substrate. The morphological characteristics of the constructed biosensor were observed by scanning electron microscopy (SEM) and electrochemical methods. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) were employed for the characterization of the proposed bioelectrode. The cyclic voltammogram appears to be more irreversible on silica coated silver core-shell nanoparticles. It is found that the fabricated immunosensor shows fast potentiometric response under the optimized conditions. The CEA could be determined in the linear range from 0.5 to 10 ng mL-1 with a detection limit of 0.01 ng mL-1 using the interface. The developed flat substrate of ITO for CEA detection (the model reagent) is a potentially promising immunosensing system, manifests good stability, and allows batch fabrication because of its economic feasibility.

Abstract
Carcinoembryonic antigen (CEA) was first identified as colon cancer antigen in 1965. The higher serum CEA level than that of healthy individuals led to its clinical application as a diagnostic biomarker for colorectal cancer. Subsequent molecular biology studies revealed that CEA are glycoproteins from a family of 32 genes and are normally expressed in various tissues. Indeed, serum CEA levels are not only increased in colorectal cancer but also increased in other types of cancers and noncancer diseases. However, a systematic comparison of the serum CEA levels in different diseases has not been reported. In current study, serum CEA levels from 70,993 patients with 49 clinically defined diseases were retrieved in the clinical laboratory of Affiliated Hospital of Qingdao University over the past 5 years. In addition, serum CEA levels from 39,650 individuals who attended their annual physical examination were used as healthy controls. Based on the mean, median, and -Log10p values, we found that patients suffering from 42 diseases had significantly increased serum CEA levels than that of healthy controls. Moreover, patients with lung fibrosis, pancreatic cancer, uremia, chronic obstructive pulmonary disease, colon cancer, Alzheimer's disease, rectum cancer, and lung cancer had highest media levels of serum CEA in a descending order. Furthermore, healthy individuals older than 65 years old ranked 24th out of 49 in the media levels of serum CEA. In summary, the increased serum CEA levels are associated with aging, cancers, and noncancer diseases and the molecular mechanisms behind the increased serum CEA levels in the 42 unrelated diseases need to be investigated.

Abstract
Carcinoembryonic antigen (CEA), the level of which is known to increase in both patients with gastrointestinal cancers and those with non-neoplastic conditions, is one of the most widely-used tumor markers. Hypothyroidism is a common endocrinological disorder in which CEA levels can rise, and is sometimes overlooked as a diagnosis in the absence of typical symptoms or thyroid enlargement. We report the cases of two patients with non-goiterous severe hypothyroidism with markedly elevated CEA levels that effectively decreased with levothyroxine replacement therapy alone. Hypothyroidism should be considered as an important cause of unexplained high serum CEA levels in order to avoid unnecessary medical examination.

Abstract
Aims To quantify the extent of squamous metaplasia in bronchial biopsies and relate it to the presence of chronic obstructive pulmonary disease (COPD), a smoking-related pathology. Methods Bronchial biopsies (n = 15 in each group) from smokers with COPD GOLD stage1 and GOLD stage2, smokers without COPD and healthy non-smokers were stained immunohistochemically with a panel of antibodies that facilitated the identification of pseudostratified epithelium and distinction of squamous metaplasia and squamous epithelium from tangentially cut epithelium. The percentage length of each of these epithelial phenotypes was measured as a percent of total epithelial length using computerised image analysis. Sections were also stained for carcinoembryonic antigen and p53, early markers of carcinogenesis, and Ki67, and the percentage epithelial expression measured. Results The extent of squamous metaplasia was significantly increased in both COPD1 and COPD2 compared to healthy smokers and healthy non-smokers. The amount of fully differentiated squamous epithelium was also increased in COPD1 and COPD2 compared to healthy non-smokers, as was the expression of carcinoembryonic antigen. These features correlated with one other. Conclusion In subjects with COPD there is a loss of pseudostratified epithelium accompanied by an increase in squamous metaplasia with transition into a fully squamous epithelium and expression of early markers of carcinogenesis.

Abstract
OBJECTIVE Carcinoembryonic antigen (CEA) is an oncofetal glycoprotein that is widely used as a tumour marker in adenocarcinomas. However, several non-neoplastic conditions, including acute and chronic inflammation and other inflammation-related conditions, are characterised by increased CEA concentrations. Bipolar disorder (BD) ranks seventh among the worldwide burden of non-fatal diseases. Inflammatory biomarkers have been considered as one of the main key pillars of a multifactorial approach for prediction of BD in an at-risk population. BP is accompanied by activation of inflammatory, cell-mediated and negative immunoregulatory cytokines. METHODS We measured the levels of CEA in serum samples from 44 individuals with euthymic BP out-patients and 45 healthy controls. Patients were diagnosed according to the DSM-IV criteria. CEA was measured by an electrochemiluminescence immunoassay. RESULTS The mean serum CEA concentration was 2.36±1.52 and 1.77±0.98 µg/l in patients and controls, respectively. CEA levels were significantly increased in euthymic BP patients when compared with controls (p=0.031). CONCLUSIONS This study suggests that CEA is increased in BD and supports a role for immune activation in the core pathological mechanisms of BP. CEA levels may be a secondary marker for diagnosing BP.

Abstract
OBJECTIVES "PAULA's" test (Protein Assays Utilizing Lung cancer Analytes) is a novel multiplex immunoassay blood test that incorporates both tumor antigens and autoantibodies to determine the risk that lung cancer (LC) is present in individuals from a high-risk population. The test's performance characteristics were evaluated in a study using 380 retrospective clinical serum samples. METHODS PAULA's test is performed on the Luminex xMAP technology platform, and detects a panel of 3 tumor antigens (CEA, CA-125, and CYFRA 21-1) and 1 autoantibody marker (NY-ESO-1). A training set (n = 230) consisting of 115 confirmed diagnoses of non-small cell lung carcinoma (NSCLC) cases and 115 age- and smoking history-matched controls was used to develop the LC predictive model. Data from an independent matched validation set (n = 150) was then used to evaluate the model developed, and determine the ability of the test to distinguish NSCLC cases from controls. RESULTS The 4-biomarker panel was able to discriminate NSCLC cases from controls with 74% sensitivity, 80% specificity, and 0.81 AUC in the training set and with 77% sensitivity, 80% specificity, and 0.85 AUC in the independent validation set. The use of NY-ESO-1 autoantibodies substantially increased the overall sensitivity of NSCLC detection as compared to the 3 tumor markers alone. Overall, the multiplexed 4-biomarker panel assay demonstrated comparable performance to a previously employed 8-biomarker non-multiplexed assay. CONCLUSIONS These studies confirm the value of using a mixed panel of tumor antigens and autoantibodies in the early detection of NSCLC in high-risk individuals. The results demonstrate that the performance of PAULA's test makes it suitable for use as an aid to determine which high-risk patients need to be directed to appropriate noninvasive diagnostic follow-up testing, especially low-dose CT (LDCT).

OBJECTIVE The aim of the present study was: (a) to measure levels of the tumor markers, Carcinoembryonic antigen (CEA), Cancer antigen 19-9 (CA19-9), Cancer antigen 125 (CA125), Neuron specific enolase (NSE) and Cytokeratin fragments 19 (CYFRA21-1); (b) to investigate any correlation between them and the inflammatory biomarkers C-reactive protein (CRP), Erythrocyte sedimentation rate (ESR) and white blood cells count (WBC), in patients with chronic obstructive pulmonary disease (COPD) exacerbation, who belong in groups of severity C and D, as classified by the Global Initiative for Chronic Obstructive Lung Disease (GOLD); (c) and finally, to compare these results in these two groups. MATERIAL AND METHODS Fifty-two patients with COPD exacerbation [35 male/17 female, mean age (± SD) 68.3 ± 6.4 years] were the study subjects, and were classified in severity groups C (n = 27) and D (n = 25), based on the spirometric classification, the number of exacerbations in the preceding year and the assessment of their symptoms by GOLD. Results. CEA and CA125 were increased in group D. In group C, there was a significant correlation between CRP and CA125 (p = 0.05). In group D, there was a significant correlation between WBC and NSE (p = 0.02), between CRP and CA19-9 (p = 0.02) and NSE (p < 0.001), and between the ESR and NSE (p = 0.03). CA125 (p = 0.01) and CA19-9 (p = 0.01) were significantly higher in group D compared to group C. In contrast, there was no significant difference in two groups for NSE, CEA and CYFRA21-1. CONCLUSION Certain tumor markers were increased and were associated with increased levels of inflammatory biomarkers and with the disease severity. Inflammation might have a key pathogenetic role linking the above tumor markers with the severity of COPD.

Abstract
BACKGROUND We investigated the clinical significance of tumor markers in patients with silicosis. METHODS Eighty silicosis patients without malignancy and 50 healthy volunteers were compared for serum tumor marker concentrations. Pulmonary function and several routine laboratory tests were performed. Correlation between serum tumor marker concentrations and severity markers for silicosis was analyzed. Tumor marker concentrations were detected in both blood and BALF samples in silicosis patients. The pre- and post-lavage differences in the serum tumor marker concentrations were also investigated. Immunohistochemical staining for tumor markers was performed in a lung biopsy specimen from a silicosis patient. RESULTS Both serum NSE and CA125 concentrations were significantly higher in cases compared with controls. Significant positive correlations were found between values of NSE and CA125 and LDH concentration. Significant negative correlations were also observed between values of NSE and CA125 and spirometric parameters. Patients with silicosis had higher concentrations of NSE in BALF than that in serum. 11 of 14 patients experienced a decrease in NSE concentrations following whole lung lavage. Immunohistochemical studies showed positive NSE staining in lung biopsy specimen. CONCLUSIONS Serum NSE and CA125 concentrations would provide valuable clinical information to assess disease severity in silicosis.

Abstract
BACKGROUND Carcinoembryonic antigen (CEA), a serological marker of malignant tumors, demonstrates a modest increase under nonmalignant conditions such as aging and smoking. Also, recent study results suggested that serum CEA levels may be related to insulin resistance or low-grade inflammation. The aim of this study was to investigate the factors associated with serum CEA levels in healthy non-smokers. METHODS Data was gathered from 21,501 adults aged 20 and over. We excluded 19,081 subjects who had omissions in anthropometric measurements or laboratory tests, or who had previous or current smoking history. RESULTS The mean CEA level was 1.18 ± 0.85 ng/dL in males and 0.93 ± 0.73 ng/dL in females. After adjustment for age, CEA level was positively correlated with fasting glucose, glycosylated hemoglobin (HbA1C), high density lipoprotein (HDL) cholesterol, estimated glomerular filtration rate in males. In females, CEA level was positively correlated with fasting glucose, HbA1C, HDL cholesterol, aspartate aminotransferase, and high-sensitivity C-reactive protein. In both gender groups, HbA1C had a strong influence on CEA levels when all other variables were included in the regression model (P < 0.05). CONCLUSION Within normal range, serum CEA levels were significantly associated with HbA1C levels but not with homeostasis model assessment of insulin resistance in the non-smoking population. These findings suggest that serum CEA levels are influenced by the glucose level itself instead of insulin resistance.

Abstract
Carbohydrate antigen 19-9 (CA 19-9) is a widely-used tumor marker in patients with pancreatic cancer. However, some patients with respiratory disease also exhibit elevated serum CA 19-9 levels. We report a case of normalization of elevated serum CA 19-9 levels after treatment of the nodular bronchiectatic form of Mycobacterium ab scessus lung disease. A 40-year-old man visited our hospital because of chronic cough and sputum. A computed tomography scan revealed severe bronchiectasis in the right upper and right middle lobes. Nontuberculous mycobacteria were repeatedly isolated and identified as M. abscessus. The serum CA 19-9 level was elevated to 142.35 U/mL (normal range, <37 U/mL). Surgical resection was performed because of failure of sputum conversion after antibiotic treatment. The serum CA 19-9 level returned to the normal range after surgery. This case suggested that serum CA 19-9 levels could be elevated in patients with the nodular bronchiectatic form of M. abscessus lung disease.

Abstract
Carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) have been well recognized as tumor markers for colorectal cancer. Previous studies suggested that obesity is inversely associated with the screening of CEA and CA19-9 levels and may reduce screening sensitivity. This study was conducted to evaluate the association of body mass index (BMI) with serum CEA and CA19-9 concentration in colorectal cancer patients. A total of 300 patients were enrolled in the study, selected from 2,950 consecutive colorectal cancer patients who underwent surgical treatment between August, 1994 and December, 2005. The association of BMI with CEA concentration, total circulating CEA mass and plasma volume was assessed by determining P-values for trends. The multivariate linear regression analysis was used to adjust for clinicopathological confounding factors to analyze the main outcome measures when CEA and CA19-9 had been log-transformed. Increased BMI was linearly correlated with a higher plasma volume. Using the stepwise method, the multiple regression model including BMI categories was reconstructed as follows: loge[CEA]=0.208+0.241[liver metastasis]+0.051 [differentiation]+0.092[TNM]; loge[CA19-9]=0.969+0.233 [gender]+0.141[ascites]+0.09[TNM]. The mean survival time in CEA+/CA19-9−, CEA+/CA19-9+, CEA−/CA19-9− and CEA−/CA19-9+ patients was 84.8, 58.2, 100.6 and 74.7 months, respectively. The 1-/3-year survival rates in each group was 76.0/59.8, 66.2/43.5, 96.3/87.6 and 71.7/41.0, respectively. In conclusion, the decreased concentration of CEA and CA19-9 in patients of higher BMIs may be the result of the hemodilution effect. The BMI factor should be considered during the surveillance of colorectal cancer. In addition, patients with simultaneous positive expression of CEA and CA19-9 exhibited shorter survival time.

Serum markers in small cell lung cancer: opportunities for improvement. Biochim Biophys Acta Rev Cancer 2013; 1836:255-72.

Abstract
Lung cancer is one of the leading causes of death from malignancy worldwide. In particular small cell lung cancers, which comprise about 15-20% of all lung cancers, are extremely aggressive and cure rates are extremely low. Therefore, new treatment modalities are needed and detection at an early stage of disease, as well as adequate monitoring of treatment response is essential in order to improve outcome. In this respect, the use of non-invasive tools for screening and monitoring has gained increasing interest and the clinical applicability of reliable, tumor-related substances that can be detected as tumor markers in easily accessible body fluids is subject of intense investigation. Some of these indicators, such as high LDH levels in serum as a reflection of the disease, have been in use for a long time as a general tumor marker. To allow for improved monitoring of the efficacy of new therapeutic modalities and for accurate subtyping, there is a strong need for specific and sensitive markers that are more directly related to the biology and behavior of small cell lung cancer. In this review the current status of these potential markers, like CEA, NSE, ProGRP, CK-BB, SCC, CgA, NCAM and several cytokeratins will be critically analyzed with respect to their performance in blood based assays. Based on known cleavage sites for cytoplasmic and extracellular proteases, a prediction of stable fragments can be obtained and used for optimal test design. Furthermore, insight into the synthesis of specific splice variants and neo-epitopes resulting from protein modification and cleavage, offers further opportunities for improvement of tumor assays. Finally, we discuss the possibility that detection of SCLC related autoantibodies in paraneoplastic disease can be used as a very early indicator of SCLC.

Abstract
Carcinoembryonic antigen (CEA) levels can be affected by many factors and metabolic syndrome is also a candidate. This study examined the relationship between CEA levels and metabolic syndrome using the data of 32,897 healthy Koreans. Fecal occult blood tests were also performed. Subjects with colorectal carcinoma were excluded. Subjects were classified by their smoking status, metabolic syndrome and its components. Prevalence of metabolic syndrome and its all components showed a significant increase according to the quartile of serum CEA concentration (P < 0.001). Increased numbers of metabolic syndrome components showed a positive association with CEA levels (P-trend < 0.001). The odds ratios for the highest CEA quartile vs the lowest serum CEA quartile significantly increased in the presence of metabolic syndrome and its components. After adjusting for age, gender and smoking status, metabolic syndrome, low high density lipoprotein cholesterol and elevated blood pressure had higher odds ratios (OR) of the highest CEA quartile compared with the lowest serum CEA quartile (OR = 1.125, 95% CI = 1.030 to 1.222, P = 0.009; OR = 1.296, 95% CI = 1.195 to 1.405, P < 0.001; OR = 1.334, 95% CI = 1.229 to 1.448, P < 0.001, respectively). These results indicate that metabolic syndrome is associated with CEA value, which may lead to a misunderstanding of the CEA levels.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a progressive and debilitating disease. Cor pulmonale, characterized by right ventricular (RV) failure, can severely influence prognosis in these patients. Hence, early recognition might be important for tailoring therapy. An old biomarker, CA-125, seems to be associated with the right heart. We aimed to show the relationship between CA-125 levels and RV failure in patients with COPD. HYPOTHESIS CA-125 might be a useful biomarker in identification of RV failure in patients with COPD. METHODS Forty patients with recent exacerbation of COPD were enrolled into the study. Another 40 age- and sex-matched individuals were enrolled for comparison. Levels of CA-125 were measured in the patients during the hospital stay. The COPD patients underwent echocardiographic study on the same day. Right-ventricular parameters were evaluated, and RV failure was identified via transthoracic echocardiography. RESULTS Patients with COPD had significantly higher CA-125 levels compared with controls (median 33.94 U/mL vs 9.76 U/mL, respectively; P < 0.001). Levels of CA-125 were correlated with systolic pulmonary artery pressure (r = 0.550, P < 0.001), tricuspid annular plane systolic excursion (r = - 0.496, P = 0.001), and tricuspid lateral annulus S velocity (r = - 0.549, P = 0.002). High CA-125 levels, obtained in hospitalized patients with COPD before echocardiography, enabled identification of RV failure with a sensitivity of 89.5% and specificity of 85.7%. CONCLUSIONS The CA-125 biomarker can be used to identify COPD patients with RV failure.
