Figure 1 Kaplan-Meier survival curves for patients affected by malignant pleural mesothelioma stratified by staging system: (A) European Organization for the Research and Treatment of Cancer (EORTC) Score; (B) modified Glasgow Prognostic Score (mGPS); (C) neutrophil-to-lymphocyte ratio (NLR).

Figure 2 Distribution of the proliferative index (A) and vascular endothelial growth factor (VEGF) expression values (B) across the two studied groups (n = 10 each). Differences in medians were tested using the Mann-Whitney U test.

Figure 3 Expression of Ki-67 and VEGF by immunohistochemistry in patients with low risk (NLR<5 and mGPS of 0–1, Group A) versus high risk inflammatory scores (NLR ≥5 and mGPS of 2, Group B). A primary mesothelioma specimen with low proliferative index (5%; Panel A); and focal VEGF expression (Histoscore = 60; Panel C) is shown. A tumour specimen with elevated proliferative index (72%, Panel B) and high VEGF expression (Histoscore = 300, Panel D) is shown. Original magnification, ×200.
