An international team of scientists has identified a protein biomarker for mesothelioma that appears to shorten survival. The biomarker is CD70. It belongs to the tumor necrosis factor (TNF) family of proteins. New research suggests that patients who express more of this protein biomarker for mesothelioma have faster-growing tumors that are less likely to respond to treatment. High CD70 levels have been linked with tumor aggression in some other types of cancer. This is the first time they have been linked to malignant pleural mesothelioma survival. CD70 and Mesothelioma Prognosis Pleural mesothelioma is a highly aggressive type of tumor. It grows on the membranes around internal organs. Mesothelioma rarely responds to standard cancer treatments. People diagnosed with pleural mesothelioma are … Continue reading Protein Biomarker for Mesothelioma Linked to Shorter Survival
A protein called transforming growth factor-beta (TGF-β) might be an effective biomarker for pleural mesothelioma. New research shows it could help diagnose the asbestos cancer and distinguish it from other lung conditions. The findings come from researchers at the West German Cancer Center in Essen, Germany. They studied patients with malignant mesothelioma, non-malignant pleural diseases or lung cancer. TGF-β levels were different in mesothelioma patients than they were in people with other diseases. They correlated with mesothelioma survival. This suggests that TGF-β could make a good biomarker for pleural mesothelioma. How Do Doctors Use a Biomarker for Pleural Mesothelioma? A biomarker for pleural mesothelioma is a substance whose presence indicates that a person has the disease. Some biomarkers occur in … Continue reading Biomarker for Pleural Mesothelioma: Transforming Growth Factor-Beta
Doctors in Michigan have launched a study to determine if volatile organic compounds (VOCs) in exhaled breath can detect early mesothelioma. They are also looking for a correlation between participants’ VOCs and biomarkers in the blood. VOCs can give doctors vital information about cellular metabolism. Previous studies of VOCs show that they can sometimes indicate the presence of mesothelioma. But no one knows yet if VOCs can really detect early mesothelioma. None of the previous studies have been big enough for the technique to be universally recommended. How VOCs Can Detect Early Mesothelioma Cancer causes biochemical changes in the body. These biochemical changes produce VOCs that a person exhales. Different types of cancer produce different combinations of VOCs. Breath testing … Continue reading Study Evaluates Breath Test to Detect Early Mesothelioma
Mesothelioma patients and their doctors may have reason to be optimistic about a new lung cancer blood test. A random trial of more than 12,000 high-risk people in Scotland shows the EarlyCDT test combined with CT imaging can detect cancer early. Earlier diagnosis is likely to lead to longer survival of lung cancers like pleural mesothelioma. Researchers presented their findings on the new lung cancer blood test at a global conference this week in Spain. Largest Lung Cancer Trial As in the US, lung cancer is the biggest cancer killer in Scotland. Pleural mesothelioma is a form of lung cancer. Although it is rare, mesothelioma is more common in the UK than in other parts of the world. This is … Continue reading Lung Cancer Blood Test: Can it Find Early Mesothelioma?
Australian researchers believe they have identified what amounts to a microRNA signature for mesothelioma in pleural effusion. Pleural effusion is the name for excess lung fluid. Up to 90 percent of pleural mesothelioma patients develop a pleural effusion. Researchers at the University of Western Australia say this fluid contains a wealth of information that could improve mesothelioma diagnosis. They have recently identified a trio of RNA molecules in fluid samples that could serve as a microRNA signature for mesothelioma. This “signature” could help doctors distinguish mesothelioma from other types of cancer. The Challenge of Mesothelioma Diagnosis Pleural mesothelioma is notoriously hard to diagnose. The early symptoms of mesothelioma are similar to the symptoms of many other lung conditions. They are … Continue reading MicroRNA Signature for Mesothelioma Could Lead to Earlier Diagnosis
New guidelines may make it easier to tell which mesothelioma patients contracted the disease because of a BAP1 gene mutation. The knowledge could have an impact on mesothelioma treatment planning. BAP1 stands for BRCA associated protein-1. People who have an inherited BAP1 gene mutation face a higher risk for several conditions, including malignant mesothelioma. Very few mesothelioma patients have the mutation and gene testing is not routine. So researchers at a top US cancer center have developed a set of screening criteria. The criteria may help predict which mesothelioma patients could benefit from genetic testing. Testing for the Altered Gene Mesothelioma is just one of the conditions associated with the inherited BAP1 gene mutation. People with this condition are also … Continue reading Spotting the BAP1 Gene Mutation in Mesothelioma Patients
A cancer research project involving dogs could eventually pave the way for an over-the-counter mesothelioma test. Researchers in Florida recently published a study suggesting that dogs may be able to detect lung cancer with surprising accuracy. If they can determine which cancer biomarkers the dogs detect, they may be able to develop an over-the-counter mesothelioma test. Can Dogs Smell Lung Cancer? The new study comes from the Florida campus of the Lake Erie College of Osteopathic Medicine (LECOM). Researchers there are working with a canine training and research firm called BioScentDX. According to LECOM, a dog’s sense of smell is at least 10,000 times stronger than a person’s. The research team chose Beagles for the tests because they are among … Continue reading Dog Research May Lead to Over-the-Counter Mesothelioma Test
Breath testing for mesothelioma may be a promising new way to catch asbestos cancer early. But Italian researchers are warning that there is not yet enough research to recommend widespread use of the technique. Malignant pleural mesothelioma is a virulent and hard-to-treat cancer. Researchers around the world continue to search for faster, easier ways to diagnose and treat it. Breath testing for mesothelioma is one proposed method. Special machines measure volatile organic compounds (VOCs) in patients’ exhaled breath. VOCs can give doctors important information about cellular metabolism and can indicate the presence of cancer. But researchers at Italy’s University of Bari analyzed all of the studies on breath testing for mesothelioma since 2000. They say none of the studies are … Continue reading Breath Testing for Mesothelioma: Not Yet Ready for Widespread Use?
If you have been exposed to asbestos and your doctor sees a mesothelioma tumor on your CT scan, it may be a waste of time to do a lung fluid test, too. Many different types of cancer cause excess lung fluid or pleural effusions. Looking for cancer cells in pleural effusions is one of the ways doctors test for cancers like pleural mesothelioma. This is called effusion cytology. But a new study says this test may not be very reliable for people with malignant mesothelioma. If other factors point to mesothelioma, they say it makes more sense to skip effusion cytology and go straight to a biopsy. Mesothelioma Develops in People Exposed to Asbestos Pleural mesothelioma is a type of … Continue reading Exposed to Asbestos? Lung Fluid Test May Waste Valuable Time
New research confirms that some mesothelioma biomarkers are much more effective than others for detecting asbestos cancer. The news comes from a study conducted at the Icahn School of Medicine at Mount Sinai in New York. Researchers ran an analysis of more than 50 studies on three popular mesothelioma biomarkers. They concluded that two of them make good mesothelioma screening tools but one of them does not. The Challenge of Early Mesothelioma Diagnosis Mesothelioma is a highly aggressive cancer caused by exposure to asbestos. As with most cancers, the odds of surviving mesothelioma are higher if it is caught early. But mesothelioma does not cause many symptoms in the early stages. This can make it challenging to diagnose. Even … Continue reading Analysis of Three Top Mesothelioma Biomarkers
