Molecular, Pathologic Intra Tumoral Heterogeneity in Malignant Pleural Mesothelioma

All patient with suspected malignant pleural mesothelioma requiring surgical biopsy after validation in oncologic multidisciplinary board will be included. During a standardized routine procedure of pleural biopsy by mean of general anesthesia and video thoracoscopic approach, 3 - 5 biopsies are realized. During this procedure, blood samples are collected and a piece of biopsy will be used for the constitution of a specific bio collection in the CRB (centre de ressources biologiques).
