Mesothelioma Blood Test Could Help Delay Time Between CT Scans

mesothelioma blood test

A mesothelioma blood test could make it possible to stretch the time between CT scans to monitor treatment progress. That is the conclusion from a team of cancer experts in Italy. The researchers compared the results of the SMRP mesothelioma blood test to CT scans and other prognostic indicators in pleural mesothelioma patients.  Doctors typically use a set of criteria called mRECIST to assess how well a particular therapy is working. mRECIST includes measurements from CT scans. But CT scans are expensive, time-consuming, and expose patients to ionizing radiation.  The goal of the new study was to see how closely SMRP levels correlated with mRECIST results. The team says the blood test appears to be accurate enough that it could … Continue reading Mesothelioma Blood Test Could Help Delay Time Between CT Scans »

Diagnostic Accuracy of Lung Fluid Tests for Mesothelioma

diagnostic accuracy

Researchers in Germany say the diagnostic accuracy of lung fluid tests for mesothelioma is high enough that they can be routinely used for diagnosis.  Right now, if mesothelioma is suspected, doctors may order a fluid test first. If the fluid test (cytology) is positive, the doctor usually orders a tissue biopsy (histology) to confirm.  But the German team says their study shows that the diagnostic accuracy of cytology is almost as good as histology for mesothelioma – especially when doctors consider the patient’s hyaluronic acid level, too. Scientists from several German institutions analyzed cytology tests from more than 4,500 suspected cases of pleural mesothelioma. They conclude that cytology is accurate enough to be used routinely for diagnosis.  The Importance of … Continue reading Diagnostic Accuracy of Lung Fluid Tests for Mesothelioma »

Misdiagnosis of Mesothelioma More Common with Cytology Alone

misdiagnosis of mesothelioma

A new set of case reports illustrates how easily misdiagnosis of mesothelioma can happen when the diagnosis is based on cytology alone.  Cytology tests look at the cells in body fluids. For peritoneal mesothelioma patients, this is often the fluid that collects in their abdomen called ascites.  But doctors from India’s Dayanand Medical College and Hospital say using ascites samples alone to diagnose mesothelioma is a risky practice. Misdiagnosis of mesothelioma may delay proper treatment and negatively impact survival. The Difficulty of Diagnosing Peritoneal Mesothelioma Malignant mesothelioma only impacts about 2,500 people in the US every year. It is most common among people who have lived or worked around asbestos. Peritoneal mesothelioma is even rarer. About a fifth of patients … Continue reading Misdiagnosis of Mesothelioma More Common with Cytology Alone »

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 »

New Cancer Blood Test May Bolster Mesothelioma Diagnostic Tools

new cancer blood test

A new cancer blood test may make boost the accuracy of current screening tools and allow doctors to detect malignant mesothelioma and other hard-to-find cancers earlier.  The test is called a multi-cancer early detection (MCED) test. The US company Grail developed it and researchers at the Cleveland Clinic tested it on more than 3,500 patients. They found that it correctly identified cancer in more than half of cases. The test was even more accurate in rare cancer types for which no screening test is available.  Malignant mesothelioma was not specifically mentioned in the report. But it is an extremely rare cancer. The method used by the new cancer blood test suggests that it could be useful for finding mesothelioma, too.  … Continue reading New Cancer Blood Test May Bolster Mesothelioma Diagnostic Tools »

Japanese Researchers Discover ‘Novel Diagnostic Marker’ for Mesothelioma

novel diagnostic marker

A protein called CDLN15 could be a novel diagnostic marker for malignant pleural mesothelioma, allowing doctors to pinpoint asbestos cancer earlier and boost the odds of survival. That is the message from a recently published Japanese study.  Pleural mesothelioma is notoriously difficult to diagnose. It rarely causes any symptoms at all until it is in a late stage. When the symptoms do show up, they are easy to confuse with other illnesses. Earlier diagnosis of pleural mesothelioma depends on finding things that set it apart from other diseases. This novel diagnostic marker could serve as a red flag for this rare but deadly cancer.  CDLN15 as a Novel Diagnostic Marker CDLN15 stands for claudin-15. Claudins are a family of proteins … Continue reading Japanese Researchers Discover ‘Novel Diagnostic Marker’ for Mesothelioma »

Artificial Intelligence Improves Mesothelioma Diagnosis, Study Finds

artificial intelligence

There is more evidence that artificial intelligence may have a role to play in helping doctors diagnose deadly malignant mesothelioma earlier.  A study conducted at Japan’s Hyogo College of Medicine used past patient records to test a deep convolutional neural network (CDNN). This is a complex computer program designed to evaluate diagnostic criteria.  Pleural mesothelioma is a difficult cancer for doctors to diagnose. Artificial intelligence can help by quickly comparing diagnostic data to hundreds of past cases. In the Japanese study, the AI produced the most accurate mesothelioma diagnoses when combined with all of the available patient data. The Challenge of Diagnosing Mesothelioma Mesothelioma tumors grow on the membranes around internal organs. They usually come from past exposure to asbestos. … Continue reading Artificial Intelligence Improves Mesothelioma Diagnosis, Study Finds »

LA Woman’s Story is a Sobering Reminder to Watch for Signs of Pleural Mesothelioma

signs of pleural mesothelioma

The plight of an LA actress who found out she had lung cancer because of a COVID test is a sobering reminder to be aware of the early signs of pleural mesothelioma. The woman’s story was recently featured on the Today Show website. Fifty-nine year old Annabelle Gurwitch is a non-smoker with no known lung cancer risk factors. She and her 23-year-old child decided to get COVID tests after her child came home from college.  Although the COVID test was negative, Gurwitch writes that doctors were concerned about her persistent cough. Ongoing cough can be a one of the early signs of pleural mesothelioma, too. An X-ray revealed that Gurwitch was suffering from Stage 4 lung cancer, the most common … Continue reading LA Woman’s Story is a Sobering Reminder to Watch for Signs of Pleural Mesothelioma »

Waiting for Medicare Coverage Could Impact Mesothelioma Survival

medicare coverage

People who suspect they may have cancer but wait to get a diagnosis until they are eligible for Medicare coverage could negatively impact their ability to survive mesothelioma.  That is the message from a new Stanford study. The study suggests that many people wait until they are 65 to seek cancer care.  For people with a fast-growing cancer like mesothelioma, delaying diagnosis by waiting for Medicare coverage could have devastating consequences.  Early Mesothelioma Diagnosis Key to Survival Malignant pleural mesothelioma is a form of lung cancer caused by exposure to asbestos. It is one of the most deadly types of cancer. Like most cancers, the chances of surviving mesothelioma are higher the earlier it is diagnosed.  But mesothelioma is not … Continue reading Waiting for Medicare Coverage Could Impact Mesothelioma Survival »

COVID-19 Fears May Lead to Delayed Mesothelioma Diagnosis

delayed mesothelioma diagnosis

Cancer experts are warning that the fear of contracting COVID-19 may result in delayed mesothelioma diagnosis and worse outcomes for some patients.  A study from the Epic Health Research Network shows that many patients delayed cancer screenings and other preventative health appointments during the pandemic.  Although the numbers have started to increase, the trend may mean that some patients have already faced a delayed mesothelioma diagnosis.  Understanding Pleural Mesothelioma Pleural mesothelioma is a fast-growing cancer on the tissue that surrounds the lungs and lines the chest wall. It is most common in people who lived or worked around asbestos.  Even in the best of times, mesothelioma is extremely difficult to diagnose. Most mesothelioma patients have very few symptoms until the … Continue reading COVID-19 Fears May Lead to Delayed Mesothelioma Diagnosis »
