Settings and Design: Two subsets of patients were recruited with lymphocytic exudative effusion, one subset constituted diagnosed patients of NSCLC with malignant pleural effusion and the other subset of constituted with Tubercular pleural effusion. Materials and Methods: CYFRA 21-1 and CEA levels were measured using Electrochemilumiscence Immunoassay (ECLIA). The test principle used the Sandwich method. For both the tests, results are determined via a calibration curve which is instrument specifically generated by 2 - point calibration and a master curve provided via reagent barcode. Statistical Analysis Used: All data are expressed as means ± SD and percentage. All the parametric variables were analysed by student-t test where as non parametric variables were compared by Mann-Whitney U-test Statistical significance was accepted for P values < 0.05. Software used were SPSS 11.5, and MS excel 2007. In order to compare the performance of the tumor markers, receiver operating characteristic (ROC) curves were constructed and compared with area under the curve (AUC). The threshold for each marker was selected based on the best diagnostic efficacy having achieved equilibrium between sensitivity and specificity. Results: In cases serum CYFRA21-1 levels had mean value of 34.1 ± 29.9 with a range of 1.6-128.3 where as in controls serum CYFRA21-1 levels had mean value of 1.9 ± 1.0 with a range of 0.5–4.7. In cases serum CEA levels had mean value of 24.9 ± 47.3 with a range of 1.0, 267.9 where as in controls serum CEA levels had mean value of 1.9 ± 1.4 with a range of 0.2-6.8. The difference in the means of serum CYFRA 21-l (P = 0.000) and CEA (P = 0.046) were statistically significant. In cases pleural fluid CYFRA21-1 levels had mean value of 160.1 ± 177.1 with a range of 5.4–517.2 where as in controls pleural fluid CYFRA21-1 levels had mean value of 15.9 ± 5.7 with a range of 7.2-29.6. In cases CEA pleural fluid levels had mean value of 89.8 ± 207.4 with a range of 1.0–861.2 where as in controls CEA levels had mean value of 2.5 ± 2.3 with a range of 1–8.9. The difference in the means of CYERA 21-1 (P = 0.001) between cases and controls is statistically significant. Conclusions: CYFRA21-1 (serum - pleural fluid) is a sensitive marker for NSCLC with sensitivity of 96.7%, highest of any combination [Serum (CYFRA 21-1 - CEA). CEA (Serum + Pleural Fluid), Pleural Fluid (CYFRA 21-1 + CEA)] and specificity of 77.8%. Levels of CYFRA21-l (serum + pleural fluid) are increased in malignant pleural effusion, so it is better to be used in suspicious malignant pleural effusion showing negative cytology, particularly in the absence of a visible tumor and or unsuitability for invasive procedure.","PeriodicalId":52464,"journal":{"name":"Journal of Carcinogenesis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82100683","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}

CCA is classified as intrahepatic, perihilar or distal extrahepatic; the individual subtypes differ in their biologic behavior, clinical presentation, and management.

In addition to known established risk factors, novel possible risk factors (i.e. obesity, hepatitis C virus) have been identified that are of high importance in developed countries where CCA prevalence rates have been low. CCA tends to develop on the background of inflammation and cholestasis. In recent years, our understanding of the molecular mechanisms of cholangiocarcinogenesis has increased, thereby, providing the basis for molecularly targeted therapies. In its diagnostic evaluation, imaging techniques have improved, and the role of complementary techniques has been defined. There is a need for improved CCA biomarkers as currently used ones are suboptimal. Multiple staging systems have been developed, but none of these is optimal. The prognosis of CCA is considered dismal. However, treatment options have improved throughout the last two decades for carefully selected subgroups of CCA patients. Perihilar CCA can now be treated with orthotopic liver transplantation with neoadjuvant chemoradiation achieving 5-year survival rates of 68%. Classically considered chemotherapy-resistant, the ABC-02 trial has shown the therapeutic benefit of combination therapy with gemcitabine and cisplatin.
