Purpose: For patients with this type of cancer, the standard of care is treatment with chemotherapy. Radiation therapy is typically not used. This is because radiation to the entire lining of the lung has many side effects that are often severe including damage to the lung (pneumonitis). There is a new radiation technique using Intensity Modulated Radiation Therapy (IMRT) that has been shown to reduce many of the side effects of standard radiation therapy. This type of radiation therapy specifically targets the lining of the lung, where you have your cancer, and reduces the risk of damaging the lung itself. The purpose of this study is to test the safety and toxicity of standard chemotherapy +/-pleurectomy/decortication followed by IMRT to the pleura in patients with malignant pleural mesothelioma.
- Arm I: Experimental
- This is a single institution phase II toxicity study of chemotherapy +/- Pleurectomy/Decortication (P/D) followed by Intensity Modulated Radiation Therapy (IMRT) to the pleura in patients with malignant pleural mesothelioma. Patients will receive up to four cycles of pemetrexed (500mg/m2) and cisplatin (75mg/m2 ) or carboplatin (AUC=5) every 3 weeks. After completion of the chemotherapy, patients who are potential candidates for pleurectomy/decortication (P/D) at the time of enrollment will have this performed and four to six weeks later they will be treated with IMRT, 50.4 Gy in 28 fractions. If patients have unresectable disease, they will be treated with IMRT, 50.4 Gy in 28 fractions after completion of the chemotherapy.
