Summary

The purpose of this study is to evaluate the safety of combining chemotherapy at different doses with a specific type of radiation therapy delivered to the entire lining of the lung to find out what effects, if any, it has on people. This radiation technique is called pleural intensity modulated radiation therapy (IMRT). IMRT specifically targets the lining of the lung (pleura) where the cancer is and reduces the risk of damaging the lung itself. When given after chemotherapy, pleural IMRT has demonstrated promising results with respect to keeping mesothelioma under control longer. However, the investigators want to determine if giving pleural IMRT at the same time as chemotherapy is safe. If safe, further studies will be done to see if chemotherapy and pleural IMRT given at the same time keeps the tumor under control for a longer period of time than chemotherapy followed by pleural IMRT.

Conditions

• Malignant Pleural Mesothelioma

Interventions

Type	Name	Description
DRUG	Pemetrexed/Cisplatin	Dose escalation of pemetrexed and cisplatin will follow the dose levels. The escalation will not exceed 500 mg/m\^2 for pemetrexed in combination with 75 mg/m\^2 of cisplatin even if the maximum tolerated dose is not identified. Each treatment cycle of chemotherapy will be 21 days. Patients will receive up to 2 cycles of chemotherapy during the radiation, and be followed for any DLT during the radiation therapy and for 12 weeks afterwards.
RADIATION	Pleural Intensity Modulated Radiation Therapy	Pleura intensity modulated radiation therapy (IMRT) will be administered over approximately 6 weeks at 50.4 Gy in 28 fractions. The prescription radiation dose may anywhere between 45 and 50.4 Gy in 25 fractions if necessary to meet the normal tissue dose constraints.
DEVICE	MRI	A pre-treatment MRI before chemo-RT will be acquired and will be used for target delineation. A three month post-treatment MRI will be acquired with the same protocol to assess the response from concurrent chemo-RT.
