Talc Pleurodesis Patients Need Alternate PET/CT Scan for Mesothelioma

PET/CT scan for mesothelioma

Certain patients may get more benefit out of an alternate type of PET/CT scan for mesothelioma. Positron emission tomography (PET) is a common tool for diagnosing mesothelioma. It is also used to monitor the effectiveness of mesothelioma treatments. Doctors often combine PET with computed tomography (CT) for an even clearer picture of mesothelioma progression. Typically, a PET/CT scan for mesothelioma involves injection of a tracer called FDG (fluorodeoxyglucose). But it turns out that PET/CT scans with this tracer do not work well for all mesothelioma patients. A new Japanese study suggests that mesothelioma patients who have had a procedure called talc pleurodesis should consider a different kind of PET/CT scan instead.

Precision Radiotherapy Method May Reduce Local Recurrence of Mesothelioma After Surgery

A radiation delivery method called tomotherapy may be more effective than conformal radiation therapy at keeping mesothelioma tumors from growing back at the original spot after surgery. That is the conclusion of UCLA researchers who compared tomotherapy and 3D conformal radiation therapy (CRT) in 45 patients with advanced pleural mesothelioma over an 8 year period. Of the forty-five consecutive patients, 23 received 3D-CRT and the other 22 received tomotherapy. Kaplan-Meier analysis was used to calculate overall survival, the time it took for a tumor to start regrowing in the same place, and the time it took for metastatic tumors to start appearing outside of the treatment field. Tomotherapy and 3D-CRT are both methods of delivering radiation into a mesothelioma tumor … Continue reading Precision Radiotherapy Method May Reduce Local Recurrence of Mesothelioma After Surgery »

Mesothelioma Prognosis Accuracy Improves with PET/CT ‘Delayed Phase’

Detecting Mesothelioma with New CT Algorithm

More research has confirmed the value of FDG-PET/CT technology for predicting treatment response in mesothelioma – especially when the scan is conducted in two phases. Positron emission tomography (PET) is a nuclear medicine imaging technique that produces three-dimensional images of functional processes in the body.  When the molecule FDG (fluorodeoxyglucose, a type of sugar) is used as the tracer, PET allows doctors to ‘see’ metabolic processes as they are happening.  Because metabolism is often higher in cancer cells, FDG-PET has proven to be a useful tool for diagnosing mesothelioma, the asbestos-linked cancer.   When FDG-PET is combined with computed tomography (CT), another powerful imaging test, the resulting images contain even more potentially crucial diagnostic, staging and prognostic information for mesothelioma. Now, a study conducted in Japan … Continue reading Mesothelioma Prognosis Accuracy Improves with PET/CT ‘Delayed Phase’ »
