    For Select Mesothelioma Patients EPP Improves Survival

    A new study has confirmed the value of the surgical approach known as extrapleural pneumonectomy (EPP) for the treatment of malignant pleural mesothelioma in select patients. The pleural membrane separates the lungs from other internal organs. Pleural mesothelioma starts in the pleural tissue where it can cause the membrane to thicken and stiffen, restricting the ability of the lungs to expand. Eventually, the pleural cancer may metastasize into the lungs and other internal membranes. Extrapleural pneumonectomy attempts to prevent the mesothelioma cancer from further spreading to other parts of the body cavity by removing the tissues most likely to be effected. During an extrapleural pneumonectomy, the surgeon removes part of the parietal pleura, or lung lining, as well as part…

    Mesothelioma and the Immune System

    The presence of an immune cell is associated with better prognosis for patients undergoing extrapleural pneumonectomy for malignant pleural mesothelioma is the conclusion of a recent article published in the Journal of Thoracic Cardiovascular Surgery.1 Canadian researchers tested mesothelioma samples removed from 32 patients (28 men and 4 women). The patients ranged in age from 21 to 74 (median age was 59). The researchers were looking for the numbers of specific types of immune cells. They then compared this data to the survival of the patients to see if these cell counts had any relationship with survival. They found that one specific type of immune cell called CD8+ was associated with better prognosis. The study found that higher levels of…
