Serum Biomarkers in Diagnosis of Mesothelioma

Study Overview
=================
Brief Summary
-----------------
In this study, the investigators analyzed the efficiencies of hyaluronan, osteopontin, C-ERC/mesothelin, N-ERC/mesothelin and syndecan-1 serum levels, both individually and in combination, in distinguishing malignant pleural mesothelioma patients from patients with metastatic malignant pleural diseases, benign pleural diseases, and benign asbestos pleurisy.

Detailed Description
-----------------
In the year 2002, a database for the pleural diseases was constructed to be prospectively filled in the department. The findings, outcome features and characteristics of follow-up for all cases with pleural diseases have been recorded in this database. The patient data, including epidemiological characteristics, smoking status, history of other diseases and co-morbid conditions, previous asbestos exposure, medications and additional physical and radiological examination findings, including computed tomography scans, both serum and pleural fluid laboratory investigational data and indications of invasive procedures, were recorded in the database mentioned above. The methods employed in the diagnosis of patients; any complications; characteristics such as the stages of diseases, treatments, and course of treatments; and results were also recorded in the database. From the date of the first database establishment, a tissue, blood, serum, and fluid specimen bank was constructed; tissue, blood, serum and pleural fluid samples of patients, which had been taken at the beginning of diagnosis process, were stored in this bank at -80°C. The blood, serum, and pleural fluid samples of patients were stored during the diagnosis process, and if conducted, pleural tissue samples taken during invasive procedures were also stocked.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Serum N-ERC/mesothelin, C-ERC/mesothelin, hyaluronan, osteopontin and syndecan -1 level in the patients with mesothelioma, metastatic malignant pleural diseases, benign pleural diseases, and benign asbestos pleurisy. | The levels of N-ERC/mesothelin, C-ERC/mesothelin, hyaluronan, osteopontin, and syndecan-1 in the serum samples were established by Enzyme-Linked Immunosorbent Assays (ELISA) at the Division of Pathology, Department of LABMED, Karolinska Institute, Stockholm, Sweden. All analyses were performed in duplicate by researchers who were unaware of the patient diagnoses. The human N-ERC/mesothelin and osteopontin. ELISA kits were supplied by Immuno-Biological Laboratories Co. Ltd. Japan; the C-ERC/mesothelin ELISA kit was supplied by (MESOMARK™) FDI Fujirebio Diagnostics, Inc.; the hyaluronan ELISA kit (Ref. 029-001) was supplied by Corgenix company; and the syndecan-1 ELISA kit (catalog no. 950.640.096) was supplied by the Diaclone company. Analyses were conducted using a sensitivity TM XS Microplate Sample Processor manufactured by Bio-Tek Instruments Inc (Vermont, USA) in accordance with the manufacturer's instructions. The C-ERC/mesothelin levels were determined at nanomolar levels due | From January 2004 to December 2010 |
