PET/CT Scans May Be Less Accurate in Elderly Mesothelioma Patients

pet/ct scans

Researchers at Case Western Reserve are warning cancer doctors not to rely too heavily on PET/CT scans when diagnosing malignant mesothelioma – especially in older patients. PET/CT is an important tool for staging mesothelioma and can help with diagnosis. But a new case report highlights the problem of false-negative PET/CT scans.  In this case involving a 77-year-old man, PET/CT showed no mesothelioma. Even the man’s lung fluid tests were negative for mesothelioma. The case is a potent reminder that biopsy is still the gold standard for diagnosing asbestos cancer.  PET/CT Scans and Other Tools for Diagnosing Mesothelioma Pleural mesothelioma is a tricky cancer to diagnose. Most patients do not even have symptoms until the disease is in a later stage. … Continue reading PET/CT Scans May Be Less Accurate in Elderly Mesothelioma Patients »

Pleurodesis May Impact Mesothelioma Scan Results

Mesothelioma patients who undergo a procedure called talc pleurodesis (TP) for excess lung fluid may be harder to monitor with FDG-PET/CT scans afterward. Talc pleurodesis is a procedure used to manage pleura effusions, the build-up of fluid around the lungs that causes many of the most uncomfortable symptoms of malignant pleural mesothelioma. As a mesothelioma tumor spreads across the pleural lining, the body often produces fluid in response.  As this fluid fills up the pleural cavity between the mesothelial lining and the lungs it can cause pain and make it hard for the mesothelioma patient to breath. Draining the fluid and filling the space with medical-grade talc is one way to deal with the problem. But a new study suggests that … Continue reading Pleurodesis May Impact Mesothelioma Scan Results »
