This is an academic led, multicenter, randomized, 1:1, non-comparative phase II trial. Patients with early stage MPM will be randomized between~Arm A - immediate surgery: immediate P/D followed by three cycles of chemotherapy (pemetrexed 500mg/m2 and cisplatin 75 mg/m2, both drugs given on day 1, every three weeks) for non-progressing patients~Arm B - delayed surgery: three cycles of chemotherapy (same regimen) followed by P/D, for non-progressing patients.~A maximum of four weeks (±2 weeks) will be allowed between the baseline tumor assessment and the start of treatment (surgery or chemotherapy). Randomization should be done as soon as possible after baseline tumor assessment.~The primary objective of the study is to investigate the feasibility of immediate P/D followed by cisplatin/pemetrexed chemotherapy or deferred P/D after cisplatin/pemetrexed chemotherapy in patients with early stage MPM.~The results of this study will allow the LCG to take one of the arms further to a comparative study with either no surgery or EPP as control arm. The choice of the comparator will depend on the result of a parallel ongoing randomized study in the UK, comparing P/D with no surgery
