A new report says biomarkers are urgently needed to determine which patients would benefit from immunotherapy for pleural mesothelioma. Researchers made the statement in a review of immunotherapy drugs in testing for malignant mesothelioma. They say some of these drugs have proven to be more effective than others for asbestos cancer. But a set of biomarkers would go a long way to funneling patients into the right immunotherapy for pleural mesothelioma. The Status of Immunotherapy for Pleural Mesothelioma Immunotherapy is believed to be the most promising up-and-coming cancer treatment. Immunotherapy treatments harness the strength of the body’s own immune response to attack cancer or help other drugs do so. Like other types of cancer, mesothelioma cells have ways of avoiding … Continue reading Immunotherapy for Pleural Mesothelioma: Biomarkers Urgently Needed
A new report says there is much for the mesothelioma community to be excited about in the technology known as exhaled breath analysis. Several studies suggest the method is as accurate at identifying mesothelioma as some more invasive tests. Researchers at the University of Leuven in Belgium led the new study. They analyzed six other studies on exhaled breath analysis The goal was to see how accurate the method is for diagnosing mesothelioma and other asbestos diseases. The researchers conclude that things look good for exhaled breath analysis, but there is more to learn. Searching for Signs of Mesothelioma Pleural mesothelioma is an aggressive lung-related cancer caused by exposure to asbestos. It can take decades to develop, but once it … Continue reading Exhaled Breath Analysis: Is it the Future of Mesothelioma Diagnosis?
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?
