Response Evaluation in Malignant Pleural Mesothelioma

Brief Summary

Recently, a few small trials have shown promising results on value of fluoro-2-deoxy-D-glucose and positron emission tomography imaging in response assessment in Malignant Pleural Mesothelioma. These studies considered different parameters in Positron Emission Tomography (PET) analysis, mainly the standardized uptake value and volume-based parameters such as total glycolytic volume.

Primary Outcome Measures

To validate a semi-automated iterative threshold-based region growing algorithm in a previously published series of patients. [Time Frame: 4 months]

Secondary Outcome Measures

To extend the analysis to another series of consecutive patients with MALIGNANT PLEURAL MESOTHELIOMA treated with first-line pemetrexed-based chemotherapy, and to perform a combined analysis of the two groups. [Time Frame: 4 months]

To validate the new liver-based threshold semi-automated algorithm on the GE ADW4.6 workstation with the algorithm validated in step 1 in the same subset of patients. [Time Frame: 4 months]
