The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
Lung cancer is the most common cause of cancerârelated mortality worldwide in male and female.Many patients with lung cancer are in the advanced stages of the disease at the time of diagnosis. However, the poor early detection of lung cancer and ineffective treatments for advanced disease are responsible for the low overall 5-year survival rate of only 14% . Therefore, the development of noninvasive diagnostic tools for discovery of novel lung cancer specific biomarker is emerging as an important to identify early stage of lung cancer and therapeutic applications. Proteomic techniques including two-dimensional gel electrophoresis (2-DE) and differential gel electrophoresis coupled with MS technology are useful for the analysis of tumormarkers . Recently, different proteomic approaches have been used for biomarker discovery in urine samples of lung cancer patients. All of these studies have provided interesting data that contributed to enrich the urinary proteomic map of lung cancer patients.
