In external beam radiation therapy, a machine outside the body shoots a beam of X-rays or charged particles at a patient’s cancer site. There are many types of external beam radiation. Specialists use the most sophisticated kinds to treat pleural mesothelioma.

When a pleural mesothelioma patient receives radiation, it is almost always external beam radiation.
The machine that creates the radiation is usually a linear accelerator or Linac machine.
In aggressive multimodal treatment, doctors typically use radiation after surgery to kill cancer cells left behind. This strategy is associated with better survival rates for patients.
Doctors may also use radiation before or during surgery. A 2021 research study noted that patients who received external beam radiation therapy after pleurectomy and decortication surgery had an overall survival of 13.5 months.
On its own, radiation therapy can relieve chest pain by shrinking tumors. Patients can also receive radiation at the same time as chemotherapy and immunotherapy.
Radiation therapy has mild side effects compared to chemotherapy for pleural mesothelioma.
However, doctors must be cautious when giving a patient radiation therapy in the chest, as it can easily damage the lungs and heart if doctors do not aim it carefully.
Hyperthermic intrathoracic chemotherapy (HITHOC) is an experimental alternative to radiation therapy. HITHOC may benefit patients who undergo lung-sparing surgery for pleural mesothelioma.
When mesothelioma specialists use radiation, they rely on the most advanced technology available.
Radiation therapy is limited for peritoneal mesothelioma treatment. Doctors may use it to prevent surgical tools from spreading cancer cells. More substantial types of radiation treatment are too dangerous to use in the abdomen.
In traditional radiation therapy, high-energy X-rays pass through the patient’s body in a straight line.
The radiation damages the tumor but also affects the healthy tissue in front of and behind it.
Pleural mesothelioma develops in the membrane on the outside of the lungs. Radiation oncologists must use unique methods to make sure they can target cancer without hurting nearby lung and heart tissue.

Image-guided 3D radiation is advanced but not advanced enough for pleural mesothelioma.
Mesothelioma specialists constantly test the best available technology in the hopes of helping their patients live longer, better lives.
IMRT involves hitting the cancer from many different angles and changing the intensity of the radiation to suit each angle.
Radiation oncologists use image scanning and computer modeling to fine-tune the radiation treatment.
A leading-edge form of this technique is called helical tomotherapy. In this approach, a patient lies inside a donut-shaped machine. This machine can shine image-guided, intensity-modulated radiation on the patient from any angle.
Another new form is volumetric modulated arc therapy (VMAT), which is faster and more accurate than standard IMRT.
A technique explicitly developed for pleural mesothelioma patients is called intensity-modulated pleural radiation therapy (IMPRINT).
Instead of using a beam of X-rays, some specialized cancer centers can use a beam of protons to kill cancer cells.
The advantage of proton therapy is that it causes much less collateral damage to healthy cells around the tumor site.
Because there is less risk to the rest of the patient’s body, radiation oncologists can give the tumor site a more lethal dose of energy. Proton therapy is not yet a standard treatment for mesothelioma.
