Prognostic factors and the prognostic role of inflammation indices in malignant pleural mesothelioma

In this study, we aimed to investigate the prognostic factors of malignant pleural mesothelioma and the prognostic value of inflammation indices in malignant pleural mesothelioma. Between January 2002 and December 2019, a total of 132 patients (74 males, 58 females; mean age: 55 years; range, 31 to 79 years) diagnosed with malignant pleural mesothelioma were retrospectively analyzed. Patients" demographic data and laboratory results were recorded. The prognostic value of the following five inflammation indices was evaluated: neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, advanced lung cancer inflammation index, C-reactive protein/albumin ratio, and prognostic nutritional index. Of all patients, 81% (n=107) were aged 65 or older and 61.4% (n=81) had an epithelioid histology. Of 12 variables examined in the multivariate analysis for their relationship with survival, age ≥65 years, non-epithelioid subtype, and prognostic nutritional index
