Mesothelioma Radiation
Mesothelioma Guide » Mesothelioma Treatment Options » Mesothelioma Radiation
Radiation therapy is an effective treatment option for patients with malignant mesothelioma. It works best in combination with other treatments such as surgery.
Treatment for All Stages of Mesothelioma
Radiation therapy is effective in treating patients with all stages of malignant mesothelioma. It is best used to shrink or stunt the growth of cancerous tumors. In patients with early stage mesothelioma, radiation is often combined with curative surgical treatments. In the advanced stages, it is used to provide pain relief to patients.
Benefits of Radiation Treatment
Improve Life Expectancy
Radiation treatment used in a multimodal setting before and after surgery has had the result of increasing life expectancies in some cases.
Target Mesothelioma Tumors
Innovative radiation techniques can be used to directly target tumors, sparing healthy cells and tissue.
Pain Relief
Radiation treatment is used for pain relief purposes in patients in all stages of mesothelioma by shrinking tumors.
Specialist Care
Mesothelioma is a rare cancer, and most oncologists don’t have extensive experience treating it. It’s important to find a doctor who specializes in mesothelioma treatment. A patient’s doctor (or team of doctors) recommends a treatment plan for them, which may include radiation. If so, a radiologist or radiation oncologist consults with them.
Patients should seek out radiation oncologists who have experience treating mesothelioma. Patients having difficulty finding the right mesothelioma specialist can use our free Doctor Match program to connect them with a specialist.

How to Get Radiation for Mesothelioma
If you want to learn more about radiation or how to start radiotherapy for mesothelioma, stick to these three steps:
- 1Meet with a mesothelioma specialist at a cancer center. They’ll provide their expert insight into your treatment options and explain the positives and concerns regarding radiation for mesothelioma. They’ll also either work directly with a radiation oncologist or can refer you to one.
- 2Learn the different types of radiotherapy. The traditional type is called photon radiation, but other methods have emerged in the 21st century. Intraoperative radiotherapy may also be an option if you’re eligible for surgery.
- 3Meet with a radiation oncologist. Learn your schedule for treatment, including how many sessions you’ll have and how much time is in between each one. They’ll also go over the side effects you might experience.
Radiation Basics
Radiation therapy consists of noninvasive treatment sessions. During these sessions, high-energy beams such as gamma rays or X-rays are used to target malignant tumors.
Radiation oncologists prepare patients for their treatment by performing a simulation, which maps out the region and allows for doctors to ensure exact targeting. Treatment itself is painless and lasts only 5-10 minutes. The entire office visit only lasts around 30 minutes.
Patients simply come into the office and lie still while the radiation targets the cancerous tumor. Side effects like nausea or general fatigue may occur following procedures, but this is normal. Radiation therapy is a key tool in the fight against mesothelioma and most patients believe the benefits outweigh the side effects.
Studies also show that after a radical surgery, such as an extrapleural pneumonectomy (EPP), the combination of radiation and chemotherapy improves life expectancy. Some patients have lived five years or longer with this treatment combination.
Radiation Treatment Options
There are different types of radiation therapy that are used on mesothelioma patients. These options are considered after examining tumor size, metastasis, staging and general health. There are two general types of radiation therapy: external beam radiation and intraoperative radiation therapy.
External Beam Radiation
External beam radiation is effective for all stages of mesothelioma and is noninvasive. There is typically no preparation for external beam procedures. This method of radiation has significantly improved life expectancies in patients who combined this treatment with chemotherapy.
External beam radiation methods for mesothelioma include:
- X-ray Radiation
- CT Scan Radiation
- 3D Conformal Radiation
- Intensity-Modulated Radiation Therapy
Intraoperative Radiation Therapy (IORT)
IORT applies radiation directly to tumors during surgery. This allows doctors to avoid passing radiation through healthy tissue. IORT is used in early stage patients who are eligible for surgery. The use of IORT during surgery has contributed to increased survival times in many patients.
Surgery for Mesothelioma After Radiation Therapy (SMART)
SMART is a multimodal treatment procedure that uses Intensity Modulated Radiation Therapy (IMRT) prior to undergoing a radical extrapleural pneumonectomy (EPP).
This is a relatively new and somewhat unconventional procedure, as it administers large doses of radiation first. Multimodal treatments with surgery and radiation typically apply the radiation following surgery. With the SMART method, a higher level of radiation can be administered with less fear of harmful side effects to the patient, as the toxic area is then removed in surgery.
The purpose of combining IMRT and the EPP is to kill mesothelioma cells surrounding tumors in the lung. This also makes surgery more successful, as it removes a larger percentage of the cancer.
Using the SMART procedure, patients are given IMRT over a period of five days prior to surgery. This procedure has shown better results than post-operative radiation in terms of survival and reduced side effects.

Radiation Therapy Process
Many patients ask about what they can expect when receiving radiation therapy. There are a series of general steps that often take place in the treatment process:
Consultation Visit
Patients speak with a radiation oncologist who determines the best type of radiation therapy to use. This specialist answers questions and helps determine a treatment plan. Patients are requested to bring all previous documentation with them. This includes X-rays, CT scans, MRIs, lab studies and other diagnostic tests. The physician performs a thorough examination and makes a recommendation for treatment.
Informed Consent
Prior to any procedure, patients have the right to understand their treatment plan, including any and all tests they’ve elected to undergo. Once patients confirm they understand their rights and the extent of treatment, they sign a consent form. However, patients may withdraw or amend their consent form at any time.
Imaging Simulation
Using a CT machine, also known as a simulator, a “map” of the location to be targeted with radiation is created. This only takes about an hour or so and is noninvasive. Simulation provides radiation specialists with the best imaging of the region they’ll be treating. It’s a critical step in the process of determining the best way to use radiation to affect the tumor.
Tattooing / Protective Coverings
In some cases, a soft ink is used to mark the spot of the treatment beams. The tattoo is nearly invisible to the naked eye, but plays an important role in ensuring the most accurate treatment. Also, depending on the location of the tumor, molds can be created to protect certain areas of the body (the face, for example), from errant radiation.
Treatment Day
Treatment begins after confirmation of treatment plans and configurations. The average length of time for the daily treatment is 15-30 minutes and is performed five days per week. In rare cases, patients may receive two treatments per day. Generally, these treatments go on for 3-10 weeks but may be altered by the doctor. The technicians take X-rays once every week to confirm that the treatment has targeted the right location. Patients take part in follow-up appointments as well.

Radiation Prognosis
It’s accepted in the mesothelioma medical community that radiation therapy alone doesn’t cure mesothelioma. However, epithelioid pleural mesothelioma patients who receive radiation therapy in conjunction with a curative surgery (such as EPP) have a 40% life expectancy improvement over surgery alone.
This is well above the average 16 months survival and continues to increase as further treatments are developed. Stage 1 and stage 2 patients who receive radiation in concert with a successful extrapleural pneumonectomy see a 30% decrease in risk of cancer recurrence.
Jodi Page

Jodi Page was diagnosed with epithelioid pleural mesothelioma at age 26. Jodi underwent an extrapleural pneumonectomy followed by three weeks of radiation therapy to prevent seeding – which is the tendency of cancer cells to reappear at the numerous incision points form the surgery.
The radiation treatment was administered twice a day, everyday during this time. Over a decade later, Jodi is living healthily and has no signs of mesothelioma. Her specialists considered her radiation treatment a success.

Improving Radiation Treatments
Radiation is an effective component of a mesothelioma treatment plan, but it has its drawbacks. Organs and tissue may be damaged when the body experiences high levels of radiation. Radiosensitizers and radioprotectors may modify the reaction to radiation.
Radiosensitizers
Radiosensitizers are intended to enhance the tumor killing process while minimizing damage to human tissue. Many of these radiosensitizers contain oxygen. As tumors grow, they become more deficient in oxygen (hypoxia), causing the cells around them to weaken.
When these cells weaken, they can no longer fight the tumor as efficiently. Radiosensitizers introduce more oxygen, which results in an increase in the effectiveness of radiation. Cisplatin is a widely used chemotherapy drug that also makes cancer cells weaker because it contains radiosensitizers.
Radioprotectors
Radioprotectors act as shields for healthy cells as radiation enters the body. Although these cells are not fully protected, the drug also helps to repair them. These protectants block oxygen from getting to the tumors, but not to the healthy cells. When tumors become more hypoxic (oxygen deficient), they cannot grow or spread as quickly.

Improve Your Prognosis With Radiation
Patients with mesothelioma are very likely to receive radiation because of its ability to shrink tumors and slow the growth of cancer. Radiation treatment is usually noninvasive and mesothelioma patients from stages 1-4 may be treated using it. Patients can expect to spend 15-30 minutes per day, five days per week receiving their treatment.
While radiation treatment is not used in a curative manner on its own, it is highly effective as a complementary treatment option. Radiation therapy is found to improve life expectancy, decreasing the cancer recurrence rate. Get connected with a mesothelioma specialist who can offer the radiation treatment that is right for you.

Common Questions About Radiation for Mesothelioma
Are there different types of radiation for mesothelioma?
There are three variations of radiation for mesothelioma: photon, proton and intensity-modulated therapy. Photon radiation is the traditional X-ray type, also known as external beam radiotherapy. Intensity-modulated radiation therapy conforms the beam to the shape of the tumor. Proton radiation uses proton beams rather than X-rays, which reduces damage to healthy tissue.
What are the common side effects of mesothelioma radiation?
Damage to healthy lung tissue is the most common side effect of mesothelioma radiation. This damage can cause scarring, which is a medical condition called pulmonary fibrosis. Other side effects include:
- Nausea
- Fatigue
- Skin problems (itchiness, dryness or peeling)
- Coughing
- Shortness of breath
Does radiation improve mesothelioma survival?
Radiation can improve mesothelioma survival and offers the greatest benefit when paired with other therapies. The combination of surgery and radiation can lead to post-treatment survival of 30 months. In one study conducted at Michigan Medicine, radiation before surgery led to a median survival of more than four years.
Where can I get radiation for my mesothelioma?
Most cancer centers offer radiation as a treatment option. If the center has a dedicated team for mesothelioma cases, they’ll almost certainly have state-of-the-art radiotherapy equipment and an on-staff radiation oncologist. Our Doctor Match service can help you find a hospital offering radiation as part of its treatment protocol.
