Using CT Scans in Surgical Decision-Making in Peritoneal Mesothelioma

ByHolly Zink

Peritoneal mesothelioma is caused by asbestos. The peritoneum is the space in your abdomen that contains the intestines, the stomach, and the liver. The abdomen (peritoneum) is the second most common site of mesothelioma after the pleural (lungs and chest). Most doctors believe peritoneal mesothelioma is caused by the ingestion of asbestos fibers. Microscopic asbestos fibers become embedded in the abdomen (peritoneum). After about 20-50 years, these fibers can cause inflammation and mutations in the healthy mesothelial cells. These mutations may ultimately cause these cells to become cancerous. Thus, forming tumors in the peritoneum. Patients diagnosed with peritoneal mesothelioma may survive several or more years after diagnosis. There are long-term survivors, such as Paul Kraus.

Mesothelioma and MRI Scans: Using an Old Tool in a New Way

ByHolly Zink

Imaging scans are an important tool in helping clinicians diagnose mesothelioma. These scans include X-rays, CT scans, MRI scans, and PET scans. These tools help clinicians to see tumors inside a patient’s body. The results of the scan cannot diagnose mesothelioma, but it is an important tool for arriving at the correct diagnosis. Unlike X-rays and CT’s, magnetic resonance imaging (MRI) scans use a completely different type of radiation. An MRI applies a very strong magnetic field to change the spin of protons. The scanner also produces a radio frequency. This process produces a signal that can be made into an image. Until now, the role of MRIs has been limited in mesothelioma. However, new evidence suggests MRIs can be…

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

ByAlex Strauss

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….

MRI Imaging May Be Superior to CT for Pleural Mesothelioma Diagnosis and Staging

ByAlex Strauss

When it comes to diagnosing and monitoring treatment response in people with pleural mesothelioma, MRI imaging may be better than CT.  That is the message from a new Italian study published in the online medical journal Cancers.  RIght now, CT (computed tomography) is the most popular form of imaging for pleural mesothelioma. Cancer doctors use CT images to help diagnose mesothelioma. They also use it to see how widespread the cancer is and to find out if treatment is making a difference.  But radiology researchers at Pisa University Hospital say MRI imaging has advantages over CT for people with the rare asbestos cancer.  Mesothelioma Diagnosis and Prognosis  Malignant pleural mesothelioma is the most serious of several health conditions linked to…

CT Scans Fail To Identify Metastatic Mesothelioma Prior to Surgery

CT Scans Fail To Identify Metastatic Mesothelioma Prior to Surgery

ByAlex Strauss

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…

Predicting Mesothelioma Outcomes with FDG-PET: A New Model

ByAlex Strauss

Swiss doctors have created a new tool for predicting mesothelioma outcomes with FDG-PET scans.  FDG-PET scanning is a nuclear imaging technique. It gives doctors a non-invasive way to track the growth of pleural mesothelioma tumors.  The Swiss team analyzed multiple PET scans and CT scans from mesothelioma patients. They used a computer to look for commonalities in the scans. Then they used the information to create a computer model for predicting mesothelioma outcomes with FDG-PET. The model may help doctors and patients make better decisions about mesothelioma treatment in the future.  Imaging Studies for Mesothelioma Prognosis Pleural mesothelioma tumors occur on the pleural lining around the lungs. In the early stages, mesothelioma causes few symptoms. As mesothelioma tumors grow, they…

Diagnostic CT Scan for Mesothelioma: More is Better

Diagnostic CT Scan for Mesothelioma: More is Better

ByAlex Strauss

A new report out of the UK suggests that a thorough diagnostic CT scan for pleural mesothelioma should include images of the abdomen and pelvis, as well as the chest.  When a person goes to the doctor with early signs of malignant pleural mesothelioma, a CT scan of the chest is often the next step in making a diagnosis. CT scans create a 3-dimensional image of internal organs, making it easier to spot mesothelioma tumors.  But a research team led by the University of Bristol says a diagnostic CT scan that shows only the chest might miss mesothelioma tumors in other areas. How a Diagnostic CT Scan Works CT stands for computerized tomography. CT scanning is an advanced type of…

Invasiveness of Peritoneal Mesothelioma: MRI Beats CT for Assessment

ByAlex Strauss

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…

Tracking Mesothelioma Recurrence: FDG-PET/CT Versus CT

ByAlex Strauss

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…

Talc Pleurodesis Patients Need Alternate PET/CT Scan for Mesothelioma

Talc Pleurodesis Patients Need Alternate PET/CT Scan for Mesothelioma

ByAlex Strauss

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. How Does Talc Pleurodesis Impact PET/CT Scan for Mesothelioma?…
