Mesothelioma Chemotherapy with Avastin Helps Pain, Neuropathy

ByAlex Strauss
mesothelioma chemotherapy with Avastin

New evidence suggests that supplementing standard mesothelioma chemotherapy with Avastin (bevacizumab) may lead to less pain. It may also reduce the risk of another mesothelioma complication called peripheral neuropathy.

That word comes from a newly-published study involving several French hospitals. The study is a follow-up to the French-led MAPS study from 2016.

The MAPS study showed that performing mesothelioma chemotherapy with Avastin – in addition to the standard chemotherapy drugs – improved mesothelioma survival by 23 percent.

Now it looks like the three-drug combination can also help mesothelioma patients live longer with fewer side effects.

Mesothelioma Complications and Side Effects

Avastin is a VEGF inhibitor. It works by preventing the formation of blood vessels that feed a growing tumor. The primary goal of the MAPS trial was to assess the survival impact of mesothelioma chemotherapy with Avastin. The second goal was to see how it affected quality of life.

Four hundred and forty-eight patients with advanced pleural mesothelioma enrolled in the MAPS study. The study ran from 2008 to 2014. Some of the patients had chemotherapy with Avastin while others had chemotherapy without it.

Ninety-four percent of the patients filled out a questionnaire about their quality of life as it relates to their health.

The questionnaire included general questions about life with cancer. It also had more specific questions related to lung cancer. Patients filled it out at the beginning of their mesothelioma treatment and again every nine weeks until their cancer progressed.

Life is Better After Mesothelioma Chemotherapy with Avastin

Pleural mesothelioma and treatment can trigger some uncomfortable symptoms. It is common for patients to have chest pain caused by the growing tumor or fluid collection around the lungs.

Peripheral neuropathy can also be a problem. This is a set of symptoms caused by damage to the nerves that control the arms and legs. Some chemotherapy drugs can cause peripheral neuropathy in mesothelioma patients.

But researchers found that the Avastin group lived longer without either of these problems. Many of the patients who had mesothelioma chemotherapy with Avastin were not bothered by peripheral neuropathy for a year or more. Patients who had no Avastin started having problems related to peripheral neuropathy at a median of 7.59 months.

The Avastin group also had less pain than the no-Avastin group. There was no negative impact on quality-of-life from mesothelioma chemotherapy with Avastin.

Since the MAPS study, chemotherapy with Avastin, Alimta (pemetrexed), and cisplatin has been the standard of care in France.

The US National Comprehensive Cancer Network guidelines have also included this combination as an option for first-line mesothelioma treatment since 2016.

    Doctors Describe "Concrete Therapeutic Approach" for Mesothelioma

    ByAlex Strauss

    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…

    Mesothelioma Still Rising Despite Ban in Ireland

    ByAlex Strauss

    A study in Ireland confirms that it can take many years for a ban on asbestos to have a measurable impact on a country’s rates of malignant mesothelioma. Mesothelioma is the most serious of a list of diseases – including lung cancer, pleural plaques, asbestosis, and others – linked with exposure to asbestos dust. Affecting the linings around the lungs and other organs, mesothelioma is often resistant to most cancer treatments and may be fatal within a year of diagnosis. According to the International Ban Asbestos Secretariat, Ireland is one of 55 countries that have enacted some type of asbestos ban. However, although Ireland banned asbestos in 2000, a new study published in Cancer Epidemiology shows that incidence of the…

    Does Radiotherapy Reduce Mesothelioma Pain?

    ByAlex Strauss

    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

    ByAlex Strauss

    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…

    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…
