A Better Way to Diagnose Mesothelioma?
New research suggests there may be a less invasive way to accurately diagnose malignant pleural mesothelioma. Right now, the gold standard for mesothelioma diagnosis is examination of suspected tumor cells under a microscope. To get those cells, doctors have to perform either an open surgery called thoracotomy or a less invasive operation called thoracoscopy using smaller incisions and a camera for guidance. But biomedical engineers at Carnegie Mellon University in Pittsburgh say analyzing cells in the fluid around the lungs may be just as effective. Unlike diagnostic methods that use tissue samples, the pleural fluid method requires only a thoracentesis, or removal of a sample of lung fluid using a needle. To maximize the diagnostic power of fluid samples, the…
