Lung cancer is the most common cause of malignant pleural effusions (MPEs). For patients with lung and MPE, median survival only 3-4 months. The aim this study was to evaluate MPE by clinical laboratory findings on admission, determine 2-year rate prognostic factors.Between 2008 2011, we examined 199 cases non-small cell carcinoma MPE. Demographic factors patients, tumor characteristics, treatment delivered parameters affecting prognosis were evaluated. Survival rates estimated Kaplan-Meier...
