Palliative Radiotherapy for Mesothelioma Produces “Substantial Treatment Response”

palliative radiotherapy for mesothelioma

Doctors in Pennsylvania may have found a way to boost the effectiveness of palliative radiotherapy for pleural mesothelioma. Palliative radiotherapy is used to help with mesothelioma symptoms. It uses lower doses of radiation. Doctors do not expect to treat mesothelioma with palliative radiotherapy. But researchers at the University of Pennsylvania think it could also be a treatment. They combined palliative radiotherapy with a special kind of gene therapy. The gene therapy affects the immune system. They say the combination produced a “substantial treatment response” in a man with mesothelioma. Immuno-gene Therapy and Palliative Radiotherapy Immuno-gene therapy uses genes to stimulate the immune system against cancer. In the new Pennsylvania case study, a 67-year-old man with mesothelioma received immuno-gene therapy. Doctors … Continue reading Palliative Radiotherapy for Mesothelioma Produces “Substantial Treatment Response” »

Chemoimmunotherapy Called “Next Frontier” for Mesothelioma Cancer

mesothelioma cancer treatment

Mesothelioma researchers in Australia are calling the combination of chemotherapy and immunotherapy the “next frontier” in the treatment of mesothelioma cancer. In a study published in the journal Expert Opinions in Biological Therapy, the researchers reviewed past clinical trials on mesothelioma immunotherapy. They focused on studies published between 2016 and 2018. Their goal was to get a clearer picture of just how effective these drugs are and how they might be used in combination with other treatments. Chemotherapy for Mesothelioma Cancer Currently, immunotherapy is not the primary treatment for mesothelioma cancer. Instead, most patients have chemotherapy, which is considered the gold standard treatment. For the past 15 years, Alimta has been the main chemotherapy drug for people with malignant mesothelioma. … Continue reading Chemoimmunotherapy Called “Next Frontier” for Mesothelioma Cancer »

Flaxseed Compound May Help Prevent Malignant Mesothelioma and Asbestosis

prevent malignant mesothelioma with flaxseed compound?

There is new evidence that a compound found in flaxseeds may help prevent malignant mesothelioma and other asbestos-related diseases. The compound is an anti-inflammatory which appears to calm down the overactive immune system after asbestos exposure in mice. Inflammation has long been considered a key factor in the development of mesothelioma. Scientists are hopeful that preventing it may also prevent malignant mesothelioma. Inflammatory Response to Asbestos Exposure Asbestos is a group of naturally-occuring minerals that cause cancer in people and animals. When a person accidentally breathes in or swallows asbestos fibers, they trigger an inflammatory response that can last for years. White blood cells flock to the area and damaging free radicals are produced. Over time, some cells may become … Continue reading Flaxseed Compound May Help Prevent Malignant Mesothelioma and Asbestosis »

New Mesothelioma Clinical Trial Will Test Personalized Immunotherapy

mesothelioma clinical trial of dendritic cells

A Dutch company has recruited the first patients into a pivotal mesothelioma clinical trial of autologous dendritic cells. Dendritic cells are immune system cells that work as messengers. They help tell T cells to attack cancers like malignant mesothelioma. The new mesothelioma clinical trial will test using the patient’s own dendritic cells (autologous cells) as a way to keep cancer from coming back after mesothelioma treatment. Expanding Mesothelioma Treatment Options There is only one approved treatment for malignant pleural mesothelioma. This “standard of care” treatment is chemotherapy with Alimta (pemetrexed) and cisplatin. Although most mesothelioma patients receive this treatment, very few live longer than a year after diagnosis. A Netherlands-based company called Amphera is trying to change those odds. Its … Continue reading New Mesothelioma Clinical Trial Will Test Personalized Immunotherapy »

PARP Inhibitors Could Enhance Immunotherapy Response in Mesothelioma

mesothelioma immunotherapy response

A new study suggests that drugs known as PARP inhibitors may enhance immunotherapy response in mesothelioma patients. According to a report published in the Journal of Clinical Investigations, PARP inhibitors worked especially well in cancers with mutations in their DNA repair genes. Some malignant mesothelioma patients have mutated DNA repair genes. In these patients, a PARP inhibitor may modify immunotherapy response, making drugs like Keytruda work better. How PARP Impacts Immunotherapy Response PARP stands for poly (ADP-ribose) polymerase. It represents a family of proteins involved in a number of cellular processes, including DNA repair. PARP is also involved in apoptosis, or programmed cell death. Olaparib (Lynparza) is an example of a PARP inhibitor. PARP inhibitors attack tumors that already have … Continue reading PARP Inhibitors Could Enhance Immunotherapy Response in Mesothelioma »

Mesothelioma Research Demonstrates Power of Intrapleural Immunotherapy

X-ray showing location of intrapleural immunotherapy

New metadata suggests that intrapleural immunotherapy is a powerful, targeted way to treat malignant pleural mesothelioma.   Pleural mesothelioma is a deadly cancer of the lining around the lungs. It is caused by asbestos exposure and is notoriously difficult to treat. Now, a new study suggests that delivering immunotherapy treatments directly into the pleural space where mesothelioma tumors form may help these drugs work even better. What is Intrapleural Immunotherapy? Immunotherapy treatments harness the immune system to help fight cancer. Immunotherapy works alone or in combination with other treatments like chemotherapy or surgery. Many researchers and doctors believe that immunotherapy is the future of mesothelioma treatment. Intrapleural immunotherapy is a more targeted way to deliver these cancer-fighting messengers. It does … Continue reading Mesothelioma Research Demonstrates Power of Intrapleural Immunotherapy »

New Mesothelioma Immunotherapy Treatment Reduces Tregs with Immunotoxin

mesothelioma immunotherapy response

There is a new mesothelioma immunotherapy treatment in the works. This one is based on reducing the number of Tregs or regulatory T-cells around a mesothelioma tumor. Tregs are an important part of maintaining balance in the immune system. They help protect people against autoimmune diseases like MS and lupus. But in people with malignant mesothelioma and other types of cancer, too many Tregs can be a problem. Tregs respond to distress signals sent out by a tumor. They surround the tumor and protect it against attack from the immune system. The goal of mesothelioma immunotherapy treatment is to reactivate the immune system to fight the cancer. Developing a Mesothelioma Immunotherapy Treatment Molecular biologists at the National Cancer Institute and … Continue reading New Mesothelioma Immunotherapy Treatment Reduces Tregs with Immunotoxin »

New Mesothelioma Drug Trial Begins

mesothelioma drug trial

A new mesothelioma drug trial is now underway. The trial will test a brand new type of immunotherapy medication called CA-170. CA-170 is designed to block an immune system suppressor called VISTA. It is the only VISTA-blocking medication currently in clinical trial. “CA-170 has demonstrated favorable safety and tolerability as well as preliminary anti-tumor activity in patients across multiple tumor types,” the company said in a statement. Mesothelioma Drug Trial Focuses on VISTA Malignant mesothelioma is highly resistant to standard cancer treatments. Many top researchers believe that immunotherapy drugs offer the best promise for curing mesothelioma. That is because cancers like malignant mesothelioma survive in part by evading detection by the immune system. They do this in a variety ways … Continue reading New Mesothelioma Drug Trial Begins »

BAP1 Can Distinguish Mesothelioma from Other Conditions

Scientist looking at mesothelioma cells

German scientists say a protein could help doctors distinguish mesothelioma from other conditions. Malignant mesothelioma is a cancer that grows on the membranes around organs. These membranes are called mesothelial membranes. But other conditions can also grow on mesothelial membranes. One of those conditions is adenomatoid tumors. Adenomatoid tumors are benign but, even under the microscope, their cells can look a lot like malignant mesothelioma. Now, a group of pathologists in Germany say the BAP1 protein can tell these two conditions apart. If doctors can distinguish mesothelioma from other conditions early enough, mesothelioma patients may have better outcomes. BAP1 Loss and Mesothelioma BAP1 is a protein encoded by the BAP1 gene. BAP1 is one of the proteins that helps keep … Continue reading BAP1 Can Distinguish Mesothelioma from Other Conditions »

Chemotherapy for Mesothelioma May Work Better with TroVax

UK researchers say a cancer vaccine called Trovax has the potential to boost the power of chemotherapy for mesothelioma. Chemotherapy is the main treatment for malignant pleural mesothelioma. Mesothelioma is a cancer of the lung lining caused by asbestos exposure. It is very hard to treat. Even people who have chemotherapy for mesothelioma do not usually live more than two years after diagnosis. Mesothelioma researchers are always looking for ways to improve chemotherapy for mesothelioma. It is often combined with other treatments like surgery, radiation or immunotherapy. Now, scientists think adding TroVax to mesothelioma chemotherapy may be another good option. What is the TroVax Cancer Vaccine? The TroVax cancer vaccine is made by UK-based Oxford BioMedica. It contains an altered … Continue reading Chemotherapy for Mesothelioma May Work Better with TroVax »
