Moving Beyond Morphology Toward a Morpho-Molecular Classification of Pleural Mesothelioma

Despite recent advances in the treatment of pleural mesothelioma, it remains a challenging and heterogeneous disease, with limited options for patients. Survival rates have only marginally improved in the past years, highlighting the need for a better biological understanding of the disease for the translation into clinical practice. Although recent years have seen substantial progress in genomics and molecular pathology, much of the existing literature has focused on morphology-correlated changes, with molecular, immunohistochemical, clinical, and blood biomarkers largely studied in a correlative framework.
