Malignant pleural mesothelioma (MPM) is a deadly disease that occurs in 2,000 to 3,000 people each year in the United States. Although MPM is an extremely difficult disease to treat, with the median overall survival ranging between 9 and 17 months regardless of stage, there has been significant progress over the last few years that has reshaped the clinical landscape. This article will provide a comprehensive discussion of the latest developments in the treatment of MPM. We will provide an update of the major clinical trials that impact mesothelioma treatment in the resectable and unresectable settings, discuss the impact of novel therapeutics, and provide perspective on where the clinical research in mesothelioma is moving. In addition, there are controversial issues, such as the role of extrapleural pneumonectomy, adjuvant radiotherapy, and use of intensity-modulated radiotherapy versus hemithoracic therapy that will also be addressed in this manuscript.

62-year-old man with shortness of breath and an abnormal chest CT Axial 3D SPGR postgadolinium images (Figure 13.8.1) demonstrate diffuse thickening and enhancement of the left pleura, with a few minimally enhancing, focal right-sided pleural plaques. Malignant pleural mesothelioma Malignant pleural mesothelioma is a rare neoplasm that originates from the mesothelial cells lining the visceral and parietal pleura. The incidence of malignant pleural mesothelioma in the United States is 15 cases per million; there is a strong correlation with asbestos exposure. Malignant pleural mesothelioma is divided into 3 histologic subtypes: epithelial (55%-65%), sarcomatoid (10%-15%), and mixed (20%-35%). Patients with epithelial malignant pleural mesothelioma have the best prognosis, and among those with limited disease who undergo extrapleural pneumonectomy (removal of the pleura, lung, hemidiaphragm, and part of the pericardium), survival is longer (5-year survival, 39%) than among all patients (median survival, 8-18 months after diagnosis)....

Abstract Background Malignant Pleural Mesothelioma (MPM) is a highly aggressive tumor which need effective therapeutic methods to improve the prognosis. We carried out this study to explore the role of miR-182 in MPM development, its correlation with Numb expression and EMT. Methods First, we investigated the level of miR-182 and Numb-mRNA by qRT-PCR. Furthermore, we introduced the putative miR-182 binding site into a luciferase reporter plasmid to illustrate the impact of miR-182 on Numb. Then, we down-regulated the expression of miR-182 with/without Numb knocked down in NCI-H2452 cells to investigated their effect. Data were presented as mean ± SD of three independent experiments. Student’s test, correlation analysis and analysis of variance (ANOVA) were used. Results Our results revealed that miR-182 has a high level of expression in MPM, it has a negative correlation with Numb and targeted Numb in MPM cells. miR-182 facilitated the invasion of MPM cells while down-regulation of miR-182 restrained the progression of EMT and made MPM cells more susceptible to pemetrexed. Conclusions miR-182 and Numb can serve as potential therapeutic targets for MPM.

e18509 Background: The prognostic systems currently in use in MPM, such as the EORTC and CALGB score, include the clinical and histological parameters, excluding the FDG-PET (PET) evaluation and the possibility of surgery. The aim of our study was to investigate the role of PET baseline SUV-max and surgery as prognostic factors in MPM. Methods: From April 2002to December 2012, 48 pts with a certain histological diagnosis of MPM underwent staging by PET scan before peri-operative (multimodality treatment) or palliative first-line chemotherapy (CT). Surgery was performed in 22(45.8%) pts. Pt characteristics: males 44(91.7%), females 4(8.3%); median age 65 (51-77) years; ECOG PS 0-1 45(93.7 %), PS 2 3(6.3 %); IMIG stage I-II 18(37.5%), III-IV 30(62.5%); histological subtype epithelial 40(83.3%), mixed 5(10.4%), sarcomatoid 3(6.3%); extrapleural pneumonectomy 8(16.8%), pleurectomy/decortication 14(29.2%), 17 (35.4%) VATS plus pleurodesis, 19(39.6%) no surgical procedures. Platinum based CT was performed in combination with pemetrexed in 39(81.3%) pts and with gemcitabine in 9(18.7%). According to the EORTC score 30(62.5%) pts were classified in the good prognosis group and 18(37.5%) as poor prognosis. The cut-off value of PET baseline SUV-max calculated by ROC analysis was 9; SUV-max at baseline PET was ≤ 9 in 32(66.7%) pts and >9 in 16(33.3%). Median overall survival (OS) was 12 (3-60) months. Results: Upon validating the impact of individual factors on OS using the Kaplan-Meier analysis, we found statistical significance was reached by histology (p=0.0038) and surgery (p=0.0027). In a multivariate analysis using the Cox regression system, considering OS as a dependent variable, according to age, histology, stage, PET baseline SUV-max and surgery, epithelial histology (p =0.002) and surgery (p=0.012) achieved a statistical significance. SUV-max at baseline PET was not statistically significant (p = 0.290), excluding it as a possible independent prognostic factor in MPM. Conclusions: This analysis does not indicate any prognostic value for baseline PET in MPM, confirming the importance of histological subtype and introducing surgery as a possible prognostic factor.
