Abstract

We report a 56-year-old man who underwent monitoring of the response to chemotherapy of malignant pleural mesothelioma (MPM). 8F-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and computed tomography (CT) were performed prior to chemotherapy and after the first and second courses of chemotherapy. The tumor lesion exhibited shrinkage on CT and a decrease in the standardized uptake value (SUV) max after the first course of chemotherapy, but exhibited size enlargement and an increase in SUV max after the second course of chemotherapy. These findings suggest that results of quantification of metabolic response by FDG-PET are related to the objective response as determined by CT in patients with MPM.
