Inclusion Criteria:

• Provide written informed consent to participate on the study
• Patients must have a pathologically confirmed diagnosis either at MSKCC or at the participating site of stage I-III malignant pleural mesothelioma
• Epithelioid or biphasic histology subtype (Note: patients with biphasic histology can have < 10% sarcomatoid)
• No evidence of metastatic disease.
• Patient age ≥ 18 years but ≤ 80 years at the time of consent.
• Karnofsky performance status ≥ 80%
• Pulmonary Function Tests:
  1. For all patients: DLCO > 40% predicted (corrected for Hgb)
  2. For patients enrolled post-P/D, only: FEV1 >/= 35% (corrected for Hgb) (Note: patients enrolled prior to P/D will have PFTs repeated pre-IMRT. If this criteria is not met, they will be removed from study)
• In cases of concern about decreased renal function and potential high radiation dose to the kidneys, an optional nuclear medicine kidney function scan may be performed prior to radiation therapy to determine the functional contribution of each kidney.
• Patient enrolled prior to chemotherapy must have adequate organ function as indicated by the following laboratory values:
  1. Absolute neutrophil count ≥1.5 K/mcL
  2. Platelets ≥100 K/mcL
  3. Serum total bilirubin ≤ 1.5 X ULN
  4. AST (SGOT) or ALT (SGPT) ≤ 3.0 X ULN Note: patients enrolled after chemotherapy do not have to meet the above criteria

Exclusion Criteria:

• > 10% Sarcomatoid or desmoplastic histology
• Continuous oxygen use
• Prior nephrectomy on the contralateral side of MPM

• Prior thoracic radiation therapy preventing hemithoracic pleural IMRT
• Bulky disease in the fissure preventing lung-sparing pleural IMRT
• Patients undergoing extrapleural pneumonectomy
• Patients with an active infection that require systemic antibiotics, antiviral, or antifungal treatments
