Neutrophil: Lymphocyte and Platelet: Lymphocyte Ratios is a Predictor of Survival in Malignant Pleural Mesothelioma

Malignant pleural mesothelioma is a tumor with aggressive course and limited therapeutic options which arises from serosal cells lining pleural cavity. It is estimated that there are annually 500-600 new MPM cases in Turkey and overall 30,000 MPM cases worldwide (Stahel et al., 2010; Utkan et al., 2013). It is rarely seen, although its incidence is tended to increase. The MPM incidence increases by age with male predominance. Asbestos and erionite are known causes in the etiology (Ibrahim et al., 2013). There is a widely accepted that MPM has no benefit from anti-tumor therapy and therapeutic options have no contribution to prognosis; in addition, no standard treatment protocol has been yet established. Many clinics consider that supportive therapy is sufficient. Currently
