CT Scans Fail To Identify Metastatic Mesothelioma Prior to Surgery

CT scans

CT scans are not a reliable way to detect the spread of mesothelioma into certain lymph nodes between the ribs. This is important because people with mesothelioma cells in their posterior intercostal lymph nodes (PILN) do not tend to get good results from P/D surgery. Surgeons need a good way to find mesothelioma cells in these lymph nodes before they decide to perform this risky operation. But University of Pennsylvania researchers say CT scans are not the best method.  CT Scans in Mesothelioma Diagnosis and Prognosis CT stands for computerized tomography. A CT machine uses a series of X-ray images from different angles to create a 3D picture of a mesothelioma tumor. Most hospitals have a CT scanner. They are … Continue reading CT Scans Fail To Identify Metastatic Mesothelioma Prior to Surgery »

Invasiveness of Peritoneal Mesothelioma: MRI Beats CT for Assessment

invasvieness of peritoneal mesothelioma

New research shows MRI beats CT when it comes to measuring the invasiveness of peritoneal mesothelioma. Scientists from several of the top US cancer centers ran the study. It included nearly 500 mesothelioma patients and appears in the journal Clinical Colorectal Cancer.  The study shows that the invasiveness of peritoneal mesothelioma is more visible on MRI than it is on CT. The news could make a difference in how doctors plan peritoneal mesothelioma treatment.  Peritoneal Cancer Index and Mesothelioma Peritoneal mesothelioma cancer grows on the peritoneal membrane lining the abdomen. Like all forms of mesothelioma, it usually comes from exposure to asbestos. Peritoneal mesothelioma accounts for about a fifth of all mesothelioma cases.  Doctors assess the invasiveness of peritoneal mesothelioma … Continue reading Invasiveness of Peritoneal Mesothelioma: MRI Beats CT for Assessment »

Tracking Mesothelioma Recurrence: FDG-PET/CT Versus CT

mesothelioma recurrence

FDG-PET/CT may be a more effective way to track malignant pleural mesothelioma recurrence than contrast-enhanced CT scanning.  That is the conclusion of cancer researchers with Japan’s Hyogo College of Medicine. The researchers focused on fifty patients who underwent radical surgery for pleural mesothelioma. Afterwards, doctors used both FDG-PET/CT and contrast-enhanced CT scans to track mesothelioma progression. Two experienced examiners assessed the cases. They concluded that FDG-PET/CT was more accurate than CT for diagnosing mesothelioma recurrence. Mesothelioma Recurrence After Surgery Pleural mesothelioma is one of the most difficult cancers to treat. It arises in the layers of the pleural membrane that surrounds the lungs. Mesothelioma tumors tend to grow and spread quickly. Treatments like chemotherapy, surgery, and radiotherapy can sometimes slow … Continue reading Tracking Mesothelioma Recurrence: FDG-PET/CT Versus CT »

Accurate Diagnosis of Pleural Mesothelioma with History and Imaging Only

accurate diagnosis of mesothelioma

Medical history and CT imaging may be enough to make an accurate diagnosis of pleural mesothelioma, even without a biopsy. That finding comes from a team of French and Canadian researchers led by Universite Laval in Quebec.  Biopsy is usually considered critical for accurate diagnosis of pleural mesothelioma. But the French and Canadian team says imaging studies may provide enough information to make a diagnosis.  This could be especially good news for people who are not healthy enough to undergo thoracoscopy. Pleural Mesothelioma Diagnostic Procedure: First Steps Pleural mesothelioma is the most common type of mesothelioma. Mesothelioma is an aggressive cancer that grows on the membranes around internal organs.  This cancer is rare and notoriously difficult to diagnose, especially in … Continue reading Accurate Diagnosis of Pleural Mesothelioma with History and Imaging Only »

Do Mesothelioma Doctors Rely Too Much on CT?

A team of researchers in the UK say doctors may be relying too heavily on the results of CT scans to determine which patients should have invasive biopsies for suspected pleural mesothelioma. Examining tumor cells under a microscope is currently the only way to definitively diagnose malignant pleural mesothelioma. However, because getting a cell sample means that a patient has to undergo surgery, doctors typically use non-invasive tests like CT first. CT scans have become an important part of the diagnostic process for malignant pleural mesothelioma. To see how valuable these tests really are for respiratory patients, experts from the Oxford Centre for Respiratory Medicine and the Lancashire Chest Centre in Preston, UK analyzed the CT scans and final diagnoses … Continue reading Do Mesothelioma Doctors Rely Too Much on CT? »

CT Accuracy May Vary for Mesothelioma

A group of French doctors has a warning for people exposed to asbestos and concerned about the possibility of mesothelioma: watch out for false positive CT results. Their new meta-analysis of current radiological techniques found that there is a wide margin in the way CT results are interpreted in cases of cancer in the lungs and chest including mesothelioma. The study may have important implications for mesothelioma, where early, accurate diagnosis is critical. CT (computed tomography) and the newer high-resolution volume CT (HR-VCT) which takes multiple two-dimensional images, are among the most popular imaging modalities for diagnosing and staging malignant pleural mesothelioma. According to the researchers who conducted the study, part of the problem is the lack of specific training in … Continue reading CT Accuracy May Vary for Mesothelioma »
