The Role of 18F-FDG PET/CT in the Diagnosis of Malignant Pleural Mesothelioma

Description
Summary:Objective: We aimed to investigate the diagnostic efficiency of pleural thickness and mediastinal lymph nodes, size and SUVmax values in patients with a pre-diagnosis of malignant pleural mesothelioma (MPM) who underwent 18F-FDG PET/CT imaging. Methods: Fifty-four patients who were admitted to our clinic with a diagnosis of MPM and had 18F-FDG PET/CT imaging between May 2018 and February 2020 were retrospectively analyzed. 28 of the patients were female (%51,8) and 26 were male (%48,2) and their average age was 58,8. Pleural thickness values of all patients, sizes of mediastinal lymph nodes and SUVmax values of all lesions were measured. Histopathological examination after PET/CT imaging revealed MPM in 23 patients, benign pleural disease (BPH) in 20, and metastatic pleural disease (MPH) in 11 patients. Results: In the comparison between all groups in terms of median SUVmax value of pleural thickness; statistical significance was found (p=0.003). Median SUVmax parameter of pleural thickness in paired group comparisons; The median SUVmax value of the BPH group was found to be statistically significantly lower than MPM and MPH (p values p:0.034 and p:0.023 respectively). In other parameters, when MPM and other groups were compared, no statistically significant difference was found. When the cut-off value of SUVmax for detecting MPM group was taken as 6,75, it had %69,6 sensitivity and %67,6 specificity, and a statistically significant difference was found. Conclusion: It was concluded that the median SUVmax value of pleural thickness can be used to distinguish malignant pleural mesothelioma from other pleural pathologies.
