Mesothelioma Spreading to the Brain and the Role of Stereotactic Radiosurgery

Mesothelioma Spreading to the Brain and the Role of Stereotactic Radiosurgery

Researchers from the University of Pittsburgh shared a case about a mesothelioma patient whose cancer spread to their brain. Doctors used a treatment called stereotactic radiosurgery to treat the tumors in the brain.

A Glimpse into Treatment Challenges

The patient had a type of cancer called pleural mesothelioma. This cancer develops in the lining of the lungs. It is caused by inhaling tiny asbestos fibers that cause inflammation, which leads to tumors.

Pleural mesothelioma occurs in about 2,000 people in the United States every year. The disease occurs more often in men than women. It can often take around 40 years for pleural mesothelioma to begin. The symptoms might include shortness of breath, chest pain, cough, and fatigue.

Pleural mesothelioma is a rare cancer, and it is even more rare for it to spread to the brain. To help this patient feel better, their doctors used a special kind of radiation therapy called stereotactic radiosurgery.

A Case Study and the Potential of Stereotactic Radiosurgery

Mesothelioma is usually treated with a combination of surgery, chemotherapy, and radiation. A newer treatment that has recently emerged is immunotherapy.

The patient received the treatment twice to treat a total of 15 tumors in the brain. After the first treatment, the tumors responded well. Some symptoms like swelling improved with the help of medications.

But during the next three months, eight new tumors appeared, and the patient needed to have the special radiation treatment again. The treatment helped control the tumors and improved the patient’s ability to function, but the patient ultimately passed away from the cancer spreading throughout their body.

This happened one year after they were diagnosed with the disease and six months after the first stereotactic radiosurgery treatment for the brain tumors. They were receiving other treatments like immunotherapy and chemotherapy at the same time, but they couldn’t stop the cancer from spreading.

The researchers shared this case because they believe that stereotactic radiosurgery can be used by other doctors to treat mesothelioma that spreads to the brain. They also encourage more research to develop better treatments to improve the survival rate of mesothelioma.

Doctors Describe "Concrete Therapeutic Approach" for Mesothelioma

A team of medical researchers in Italy have achieved what they are calling “excellent” tumor control and survival results in malignant pleural mesothelioma patients using a combination of surgery, chemotherapy, and radiotherapy. Caused by exposure to asbestos, mesothelioma typically spreads quickly across the lung-encasing membrane called the pleura. There is no known cure but treatments are improving. In the current prospective study, 20 malignant pleural mesothelioma patients underwent radical pleurectomy/decortication followed by high doses of radiation. After surgeons removed as much of the visible mesothelioma tumor and surrounding tissue as possible, patients received 50Gy of radiation to the effected side of their chest, delivered in 25 fractions. Regions of particular concern for mesothelioma regrowth got an extra radiation “boost” to…

Does Radiotherapy Reduce Mesothelioma Pain?

A new study says there is not enough evidence to support the use of radiotherapy for the treatment of pain associated with malignant pleural mesothelioma. Researchers at the University of Edinburgh in Scotland reviewed a range of past studies on mesothelioma pain and radiotherapy by searching databases that date back as far as 1974. To be eligible to be included in their review, the study had to focus on malignant pleural mesothelioma and radiotherapy given “with the intent of improving pain”. The study also had to report doses and fractionation of the radiotherapy and how the pain responded. In all, the researchers found eight studies on mesothelioma pain and radiotherapy that met the criteria. Two of the studies were prospective…

Website Aims to Protect Homeowners from Mesothelioma

Australia’s Cancer Council is trying to educate home renovators about their risk for mesothelioma with a new e-learning course. Australia has one of the highest per capita rates of mesothelioma in the world, largely because of several asbestos mining operations that were once located there. Although asbestos has been banned from building products in Australia since 1989, asbestos-linked diseases like mesothelioma, lung cancer, and asbestosis continue to pose a serious health concern. While mesothelioma has traditionally occurred among people exposed to asbestos on the job, Australia is now bracing for another “wave” of mesothelioma victims among homeowners who encounter asbestos while doing their own renovation projects. Cancer Council Australia has launched “kNOw asbestos in your home” in an effort to…

A virus that causes leukemia in gibbon apes may have the power to help fight malignant mesothelioma in people. Gibbon ape leukemia virus (GALV) has been tested for years as a viral vector, a carrier of therapeutic genetic information, in the treatment of various human illnesses, including cancer. A new study in Japan compared GALV with a leukemia virus derived from mice to see which carrier communicated most efficiently with mesothelioma cells. While both types of viruses replicated in most of the mesothelioma cell lines tested, the mouse-derived virus was not effective in a mesothelioma cell line called ACC-MESO-1. In this cell line, only the GALV spread efficiently both in culture and in mice that had been given human mesothelioma…

Radiotherapy for Mesothelioma: Better But Still Limited

ByAlex Strauss

A form of highly-targeted radiation therapy for mesothelioma is better than it used to be, but is still risky. That is the message of a recent article on intensity-modulated radiation therapy (IMRT) in Seminars in Thoracic and Cardiovascular Surgery. Author Kenneth E. Rosenzweig, MD, a Radiation Oncologist with Mount Sinai Hospital in New York, reviewed recent studies on IMRT and mesothelioma. He concludes that, while the “troubling toxicity” associated with IMRT when it was first introduced has not been entirely eliminated, the fact that clinicians now have more experience with it is making a positive difference for mesothelioma patients. Before targeted therapies like IMRT were available, high-dose radiation was not usually a feasible option for mesothelioma since the irregular shape…

Mesothelioma Nurses Ready for New Cases in Australia

ByAlex Strauss

Australia is bracing for an expected new wave of mesothelioma cases in the next decade and the Lung Foundation of Australia is taking action now to get ready. The Foundation has paid for ten nurses from around the country to receive specialized training in helping patients and families cope with mesothelioma. The nurses, who have recently completed the training, are now equipped to lead treatment planning for these complex cancer patients and to help other nurses do the same. Pleural mesothelioma is an aggressive cancer that occurs in the lining around the lungs. It is caused by exposure to asbestos dust, a toxin that was once alarmingly prevalent in Australia where it was mined and heavily used in construction. Because…
