Thus, the authors assumed a relationship between the degree of local CXCR2 expression on EC cells and its serum concentration. Indeed, they found significantly higher serum CXCR2 levels in EC patients than in healthy controls. However, their study failed to show any relationship between serum CXCR2 concentrations and the clinical and pathological EC characteristics, found in studies on the expression of CXCR2 on EC cells.7,8 The authors emphasized that they carried out the first study evaluating serum CXCR2 concentrations in EC patients. Therefore, they could not present any data on the relationship between serum CXCR2 and its expression on EC cells. There are also no such data for other cells expressing CXCR2. Soluble CXCR2 (sCXCR2), present and measurable in biological fluids (plasma, urine), is an acidic glycopeptide identified as the N-terminal fragment of the CXCR2 molecule. It is released after proteolytic cleavage of CXCR2 by cell-associated metalloproteinases as shown for neutrophils.9 Thus, the relationship between serum sCXCR2 and CXCR2 expression may be complex. The second aim of the study was to establish the diagnostic characteristics of CXCR2 levels in the diagnosis of EC and to assess the clinical usefulness of this test. The obtained results clearly demonstrated that significant differences in serum CXCR2 levels between EC patients and tumor-free controls do not justify the measurement of this receptor to diagnose EC. CXCR2 is expressed on numerous cells, namely, on neutrophils, lymphocytes, as well as epithelial and endothelial cells, and cannot be considered a tumor-specific marker. Therefore, its serum concentration distributions in EC patients and healthy controls may overlap. The area under the receiver-operating characteristic curve (AUC) reflects the degree of overlapping of distributions. AUC for serum CXCR2 levels amounting to 0.681 found in the study indicates significant overlapping of distributions and poor overall diagnostic A tumor marker is a substance produced by or associated with a tumor, found in blood in concentrations higher than in malignancy-free subjects.1 The long history of tumor markers is a little disappointing. They were introduced on a larger scale in the years 1960–1970 with the hope that they would enable the diagnosis of malignancies at an early stage and serve as screening tests. In fact tumor markers are mainly used to monitor the course of the cancer disease after radical treatment. Rising concentrations of a tumor marker is an earlier indicator of cancer recurrence or distant metastases than clinical presentation and results of imaging studies are. Only a few tumor markers are used for screening (eg, alpha-fetoprotein in patients at risk for hepatocellular carcinoma or prostate-specific antigen together with other diagnostic too","PeriodicalId":20343,"journal":{"name":"Polskie Archiwum Medycyny Wewnetrznej","volume":"11 1","pages":"845-846"},"PeriodicalIF":0.0,"publicationDate":"2016-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89930048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
