  1. description
    All patients are on Step 1 before being randomized to Step 2. STEP 1: Patients who received allowed neoadjuvant systemic therapy before study entry undergo pleurectomy/decortication (P/D) within 4 to 8 weeks of systemic therapy. Otherwise, patients undergo P/D within 4 weeks of study entry followed within 4 to 8 weeks by four 21-day cycles of pemetrexed and cisplatin or carboplatin on day 1.

      Patients continuing to Step 2. Patients must have received at least 2 cycles of systemic therapy and undergone a pleurectomy/decortication with the goal of macroscopic complete resection; Within 30 days prior to Step 2 randomization: no evidence of progression, ECOG Performance Status 0-1, history/physical examination occurs.
