Mesothelioma Treatment

Standard treatments for malignant mesothelioma are surgery, chemotherapy and radiation. Typically treatment plans incorporate a combination of the three, if possible for the patient. For cases where standard treatments do not work, mesothelioma patients may be able to participate in clinical trials to try experimental treatments.

There is no cure for mesothelioma, but it is possible for treatment to improve patient prognosis. Treatment options will vary based on the type of mesothelioma, patient characteristics and staging. For late-stage patients, there are alternative therapies and palliative care options that can help improve symptoms and quality of life.

Standard Mesothelioma Treatments

When determining which treatment type is best for the patient, mesothelioma doctors will consider mesothelioma type, cell type and patient characteristics. The patient’s age and overall health may limit what treatment options are viable. The stage of cancer is also an influential factor. If the disease is localized, more treatment options are available than if spreading has occurred.

• 

  Surgery

  For patients with an early-stage mesothelioma diagnosis, surgery can be used to remove all or most of the tumor(s). Depending on the tumor location, surgery may include removing the mesothelial lining, one or more lymph nodes, or part or all of a lung or other organ. Radical mesothelioma surgeries that have shown success include a pleurectomy/decortication (P/D) and extrapleural pneumonectomy (EPP).

• 

  Chemotherapy

  Chemotherapy drugs work by attacking fast-growing cells, such as cancer cells. Often used in conjunction with surgery, chemotherapy can kill any remaining mesothelioma cells and help prevent recurrence.

• 

  Radiation Therapy

  Through the use of targeted radiation, mesothelioma tumors can often be shrunk, making them easier to be removed through surgery. The two primary types of radiation for mesothelioma include external beam radiation therapy (EBRT) and internal beam radiation therapy (IMRT).

In many cases, mesothelioma specialists will recommend a multimodal approach, which combines surgery, chemotherapy and/or radiation therapy, or even emerging treatments in some cases. In various studies, multimodal treatment has been shown to be more effective than any of the individual treatments alone. In particular, surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC), a heated chemotherapy wash applied directly to the abdominal cavity, has demonstrated around a 50% survival rate or higher for peritoneal mesothelioma patients in recent clinical studies. With aggressive multimodal plans, patients should be aware of all potential treatment side effects.

Clinical Trials and Experimental Treatments

Researchers and specialists continue to make advances in mesothelioma research, with efforts towards finding a cure and more effective treatment options. Before a treatment becomes approved by the U.S. Food and Drug Administration (FDA) and readily available to all patients, it’s considered an experimental treatment and only offered through clinical trials. Experimental treatments have the potential to become a standard care option if proven successful.

Malignant mesothelioma patients must meet certain criteria in order to be eligible to participate in a clinical trial. In most cases, emerging treatments are designed for patients that are in the late stages of their diagnosis and/or if the cancer is not responding to standard treatment options. Emerging treatments may be able to extend life expectancies for patients, however, patients still must meet other criteria specific to the trial, which can include a particular type and cell type, stage of disease or prior treatments received. Ultimately, patients should discuss their options with their mesothelioma doctor to understand eligibility.

Immunotherapy

Immunotherapy has been shown to be successful in treating mesothelioma and other diseases by boosting the immune system. Used on its own, immunotherapy is still a rare cancer treatment option. However, immunotherapy combined with standard treatments like chemotherapy has shown great success in the treatment of mesothelioma, in some cases extending life expectancy by months or even years.

The effectiveness of different immunotherapy drugs continues to be tested, particularly when used during a multimodal treatment plan. Types of immunotherapy that have been used include:

Gene Therapy

Gene therapy is another emerging treatment that has shown promise in treating malignant mesothelioma for some patients. Gene therapy works by repairing the genetic structure or function of cells. If repair is successful, it can potentially treat the disease or help prevent the development of diseases without as many side effects as treatments like chemotherapy or radiation therapy. Types of gene therapy include:

Epigenetic Therapy

Epigenetic therapy is a malignant mesothelioma treatment similar to gene therapy, used specifically to treat malignant pleural mesothelioma. While gene therapy targets gene sequences, epigenetic therapy targets gene expression. Patterns have been found between epigenetic patterns and the development of tumors, suggesting that changes in epigenetic patterns can turn off tumor-suppressing genes.

Epigenetic therapy can be used to help prevent the growth of tumors, metastasis (spreading of cancer), resistance to cancer treatment drugs and many other cell functions contributing to the development of cancer.

Photodynamic Therapy

Photodynamic therapy (PDT) is a relatively new treatment that uses light to target and kill cancer cells. All that PDT needs to work is oxygen, light and a photosynthesizing agent. Researchers continue to test the effectiveness of the targeted therapy and strive for drugs that can better target specific cancer cells.

Mesothelioma Doctors and Cancer Centers

Not all physicians have experience treating mesothelioma cancer. There are mesothelioma doctors around the United States who have experience treating the disease with extensive knowledge regarding the best treatment options, new treatment advances and palliative care to potentially extend patient survival and improve quality of life. Some mesothelioma experts specialize in particular types of the disease. Thoracic oncologists specialize in cancers of the chest with expertise specific to pleural mesothelioma and pericardial mesothelioma. Some specialize particularly in peritoneal mesothelioma.

If a patient is diagnosed with malignant mesothelioma, they’ll likely be referred by their primary health care physician to a larger scale comprehensive cancer institute. Cancer centers will be able to provide targeted cancer treatments, some of which are specifically designed to treat mesothelioma. Cancer centers are located throughout the country, and many are linked to top medical universities.

Palliative Mesothelioma Treatments

Palliative mesothelioma treatments may be used on their own or in conjunction with standard treatment options. These treatments aren’t used to treat the cancer, but rather to improve symptoms and quality of life for patients.

Common palliative treatments include pleurocentesis and paracentesis, which are used to drain excess fluid buildup around the lungs or abdomen. This helps alleviate symptoms associated with the fluid buildup, including chest or abdominal pain, difficulty breathing and shortness of breath.

Palliative treatments can be invasive or non-invasive, including anything from pain medication to physical therapy, massage, acupuncture, yoga and other alternative therapies. Mesothelioma patients may undergo palliative care during their treatment journey, as their sole treatment plan during the late stages of their diagnosis or after treatment.

No matter what type of treatment patients pursue, they should discuss all options with their medical care team to understand what is best for their individual case. This can also provide an idea of potential treatment costs for financial planning and decision-making.
