Case Reports Comparative Study
Treatment planning system evaluation for mesothelioma IMRT.
Malignant pleural mesothelioma (MPM) has been treated with extrapleural pneumonectomy (EPP) followed by IMRT. IMRT improved radiation dose distributions to the complex operative bed, and preliminary results suggested improved local control compared with conventional treatment planning. IMRT was initially developed on the Corvus treatment planning system. Other treatment planning systems are also IMRT-capable. Treatment plans from several systems were compared to determine the feasibility of using IMRT in a multi-institution trial. ⋯ IMRT plans can be calculated for MPM targets by at least three commonly available treatment planning systems. Pinnacle- and Eclipse-based plans seem more efficient, and may be delivered in a shorter time than Corvus-based plans.

We previously reported that F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) response correlated strongly with survival after radical radiotherapy (RT)/chemoradiotherapy for non-small cell lung cancer (NSCLC). PET-response, survival and patterns of failure data are presented with long-term follow-up. ⋯ Attainment of CMR after radical RT/chemoRT for NSCLC bestows superior freedom from local and distant relapse; late local relapse is common.
