Abstract
BACKGROUND AND AIMS: Lung cancer is the most common cause of malignant pleural effusions (MPEs). For patients with lung cancer and MPE, median survival is only 3-4 months. The aim of this study was to evaluate lung cancer patients with MPE by clinical and laboratory findings on admission, and determine 2-year survival rate and prognostic factors. METHODS: Between 2008 and 2011, we examined 199 cases of non-small cell lung carcinoma with MPE. Demographic factors of patients, tumor characteristics, treatment delivered and laboratory parameters affecting prognosis were evaluated. Survival rates were estimated by Kaplan-Meier method. Significance of each prognostic factors selected by univariate analysis were confirmed using Cox regression model. RESULTS: The study included 139 (69.8%) male and 60 (30.2%) female patients with a median age of 64 (30-85) years. Median overall survival was 4.4 months. Adenocarcinoma was the leading cause of MPE with 80.4%. A univariate analysis showed that factors affecting mortality included gender (P < 0.001), MPE with distant metastasis (P = 0.025), lower serum albumin (P < 0.0001), lower pleural protein (P < 0.0001), increased serum lactate dehydrogenase (P = 0.003), increased serum C-reactive protein (CRP) (P < 0.0001), increased white blood cells (P < 0.0001), histopathological type (P = 0.004) and treatment decision (P < 0.0001). A multivariate analysis revealed that patients who had high level of serum CRP (P = 0.017), lower serum albumin (P = 0.009) and lower pleural protein (P = 0.003), MPE with distant metastasis (P = 0.003) and those who were chemotherapy naive (P < 0.0001) had shorter survival. CONCLUSION: High level of serum CRP, lower serum albumin and lower pleural protein, MPE with distant metastasis were most important prognostic factors for non-small cell lung carcinoma in patients with MPEs.
