There is a need for new treatment strategies and prognostic markers for the management of malignant mesothelioma (MM). The activity of thalidomide/cisplatin/gemcitabine (arm A) or thalidomide alone (arm B) was investigated in two parallel phase II studies in patients with advanced MM, using 6 month progression free survival (PFS) as the principal end-point. The predictive role of pre-treatment and 8 week follow-up serum C-reactive protein (CRP), interlukin-6 (IL-6), interlukin-6 soluble receptor (sIL-6R), mesothelin (SMRP) and vascular endothelial growth factor (VEGF) was also assessed. The proportion of patients with stable disease for >6 months was similar in both studies (arm A 35%, arm B 29%) and toxicity was mainly grade I/II. In univariate analyses only pre-treatment VEGF and CRP were correlated with survival. At 8 weeks post treatment, increased survival was found with low (
