VEGFA and malignant mesothelioma: 2002; Hamed et al. 2004; Jin et al. 2004; Sack et al. 2005; Shu et al. 2007; Qian et al. 2012; Zhang et al. 2012). One study was excluded since it provided data for the S‐VEGF levels only for the malignant mesothelioma group of patients (Hirayama et al. 2011). All studies showed statistically significant higher S‐VEGF levels among patients with MPE, except for one (Sack et al. 2005).
