The Search for a Mesothelioma Cure
Although there is currently no cure for mesothelioma, there are new developments in early detection, prevention and treatment.
Research That Leads to a Cure
Mesothelioma research and clinical trials are advancing treatment by leaps and bounds. There are multiple emerging treatments that show the potential to usher in a new era of treatment and bring patients another step toward a cure.
How is Mesothelioma Treatment Progressing?
With newly developed treatments, the average life expectancy of a mesothelioma patient has improved ten-fold in the past 2 decades.
Researchers across the globe are involved in new trials aimed at early detection and treatments that help patients live longer.
More Treatment Options
There are 2 times the number of treatment options available as there were a decade ago.
There is also genomic research being conducted on the relationship of genetics and the development of mesothelioma. Researchers have found that some genes contain information in declaring when our cells grow and at what rate they grow.
Over the past two decades, many experimental therapies have emerged. This is partially due to the growing number of mesothelioma-focused clinical trials. While some of these therapies still require additional testing, the groundwork is in place for patients to benefit from them in the future. These treatments may lead to a cure.

- One-on-one care from America’s leading mesothelioma specialists and researchers.
Another innovative option in the fight against cancer is the use of immunotherapy to strengthen the body’s own immune system. Sometimes known as biotherapy, immunotherapy uses two different approaches.
The first is active immunotherapy, which uses medication to enhance the immune system. The other is passive immunotherapy, which adds laboratory-created proteins to what the body is currently lacking. Immunotherapy is currently in clinical trials to determine its effectiveness, reliability and repeatability.
The drug Avastin has recently become the first of its kind to introduce antibodies in an attempt to treat cancer and extend life. In 2012, one the largest clinical trials centered on immunotherapy began. Its purpose is to develop a pipeline of continual phase 3 clinical trials.
Researchers have found that immunotherapy is one of the most promising forms of therapy for mesothelioma patients. For certain forms of immunotherapy, like dendritic cell-based immunotherapy, cells are stimulated outside the body and then reinserted into the body attached to non-active virus.
These cells are programmed to attack the cancerous cells. Immunotherapy is being used in large cell lung cancer and mesothelioma, bringing to light possible treatments for later staged cancer patients, and hopefully an eventual mesothelioma cure.

Mesothelioma is caused by asbestos exposure, but not every person exposed to asbestos will develop mesothelioma. Certain people are more likely to develop mesothelioma because of DNA mutations. Researchers hope that genetic testing can help identify people at higher risk of developing mesothelioma.
There are several important benefits of genetic testing:
- Earlier Diagnosis: The most important benefit of genetic testing is that doctors may be able to diagnose patients earlier. Doctors can use genetic testing to screen their patients who have been exposed to asbestos for mutations that may cause mesothelioma.
- Personalized Treatment: Researchers are working to develop more personalized treatments for mesothelioma. New treatments are being created for patients with certain genes. Doctors can choose specific treatments based on their patient’s DNA.
- More Accurate Prognosis: Doctors can use a patient’s genetic makeup to give a more accurate prognosis. Genetic information can also help doctors decide which treatments will be effective in improving a patient’s prognosis.
Many cancers and illnesses are caused or affected by genetic mutations. Sometimes patients are born with these mutations but carcinogens, like asbestos, can alter DNA as well. Genetic testing can help doctors identify patients with the mutations that could cause mesothelioma.
Photodynamic therapy utilizes light reactive chemicals called photosensitizers. When these chemicals are activated with light, oxygen is released that kills nearby cancer cells.
This may also keep certain blood vessels from continuing to feed a growing tumor, stunting the tumor’s growth. The photosensitizers are introduced intravenously and absorbed by the cancer cells.
This either weakens the cancer cells, making them more susceptible to chemotherapy and radiation, or outright kills them. Some side effects are slight discomfort and bruising. Photodynamic therapy is a growing science, and the search continues for more powerful chemicals and medications to maximize the effectiveness of this method.
Dr. Joseph Friedberg is pleased with the headway taking place regarding photodynamic therapy.
“Based on our new findings,” Dr. Friedberg said, “we are redoubling our clinical and translational research efforts to find a way to further improve and refine this multimodality treatment approach for mesothelioma.”
He found that patients treated with a pleurectomy/decortication and intraoperative photodynamic therapy have lived up to two years longer than initially told.
Virotherapy is an emerging type of treatment that uses viruses to fight cancer. Virotherapy can use several different types of viruses such as vaccinia, herpes, or measles. Researchers harness the power of viruses without the harmful effects by modifying them to be safe for healthy cells.
Virotherapy treatments work in 2 different ways. Some virotherapies modify a virus to attack cancer cells. Other virotherapies infect cancer cells with a virus to stimulate a response from the immune system.
Virotherapy Drugs for Mesothelioma
- GL-ONC1 is a modified form of the vaccinia virus that can infect mesothelioma cells. GL-ONC1 replicates and grows inside the tumors, destroying mesothelioma cells one by one. The virus also emits light that is visible on CT scans making it easy for doctors to track the progress of the virus as well as the cancer.
- MV-NIS is a form of the measles virus that has been modified to target mesothelioma cancer cells without harming normal cells. Researchers also believe the drug will trigger the immune system to attack the tumors. This drug has already proven effective in treating other types of cancer.
The idea for virotherapy developed over time as doctors observed strange reactions from cancer patients when they caught a virus. Doctors noticed cancer shrinking in several patients who were infected by a virus. In 1896, a 42 year old woman with leukemia went into remission after catching the flu. In a 1970s case, a young boy with a type of lymphoma contracted the measles. A tumor on his eye shrank and disappeared.
Mesothelioma specialists prefer to treat this cancer with several different types of treatment to maximize their effects. The concept behind Surgery for Mesothelioma After Radiation Therapy (SMART) is as simple as the name.
When radiation and surgery are given together, surgery is usually done first and then radiation is performed after. The researchers who developed SMART decided to try treating patients with radiation first and then surgery. The results with SMART were incredible compared to the results from a study testing surgery first.
Without SMART, the average survival time for late stage pleural mesothelioma is about 4 to 12 months. Treatment with SMART could help patients with pleural mesothelioma significantly increase their survival time.
