3 Reasons You're Not Getting Radiation Treatment For Mesothelioma Isn't Working (And How To Fix It)
Mesothelioma Radiation Treatment

Treatment for mesothelioma with radiation makes use of X radiation and other energy beams in order to shrink tumors and halt their growth and spread. It can be utilized at any stage to prolong the life of a patient or relieve symptoms.

Radiation is also used by doctors prior to surgery to shrink the tumor, which makes it easier for surgeons. They can also utilize it following surgery to kill any remaining cancer cells and prevent the recurrence of cancer.

External beam radiation therapy

Radiation therapy utilizes high-energy beams of X-rays or particles that destroy cancerous cells. Mesothelioma tumors often grow as multiple, small regions of tissue, making it hard to aim radiation at the tumor and spare nearby healthy tissues. New methods allow doctors to better pinpoint the cancer and limit damage to other tissues of the human body. Radiation can also be used after chemotherapy or surgery to destroy any remaining cancer cells. It can be used alone or as part of a palliative treatment to lessen mesothelioma-related symptoms such as breathing difficulties and pain.

For external beam radiation therapy, doctors utilize an instrument to direct radiation towards mesothelioma from outside the patient's body. The doctors make use of a CT, MRI, or PET scan to determine the exact location of mesothelioma. They then design a plan to deliver radiation to the area, while limiting damage surrounding tissue. The radiation oncologist might mark your skin with small dots to aid in locating the area. They also mark the treatment field that is the part which needs to be treated.

You'll be lying on a treatment table, and the machine will be placed over the area of your body that is affected by mesothelioma. You may be asked to change positions a few times throughout your session, but you won't feel or see the machine moving around your. During the procedure, you might hear clicks or whirring noises from the equipment. The radiation doctor will monitor you from a room of observation.

EBRT is typically done 5 days a week, once a day, for 2-8 weeks. Based on the type of radiation you want to receive and the goal of treatment you will receive various treatments. Some EBRT treatments, such as intensity modulated radiation therapy (IMRT), use computers to pinpoint the tumor more precisely and limit radiation exposure on nearby tissues.

Other types of radiation, like proton beam radiation or SBRT, use particles instead of an X-ray. Proton beam radiation damages DNA of cancer cells, causing them to die faster than normal cells. This type of treatment could be more precise than EBRT, but it's not yet widely employed for mesothelioma.

Intensity-modulated radiation therapy (IMRT)

Intensity-modulated radiation therapy employs 3-D computed tomography (CT) images of the patient as well as computerized dose calculations to align the radiation beams with the three-dimensional shape of the tumor. This allows higher radiation doses to be delivered to the tumor while minimising the radiation exposure to surrounding organs and tissues. In addition to pleural mesothelioma treatment, IMRT is also used to treat prostate cancer, lung cancer, sarcomas and head and neck tumors.

In studies involving patients with complex tumors, IMRT produces superior dose distributions and lower toxicity when in comparison to conventional radiation techniques. Radiation oncologists plan their mesothelioma treatment plan and use IMRT to ensure that the radiation is directed towards the right part of the body. The radiation oncologist talks to the patient and obtains informed consent before determining whether IMRT is suitable for mesothelioma therapy.


The radiation oncologist and medical physicist work together to develop an individual IMRT treatment plan for mesothelioma. The radiation therapists will then administer the actual treatments using IMRT. During the sessions the patient is lying on a table. They may hear noises and smell odors of the equipment but shouldn't feel any discomfort. Medical scientists and radiation oncologists remain outside the room for an uninvolved viewing distance.

During an IMRT session an oncologist who is a radiation specialist may alter the intensity of radiation to target the tumor better. The radiation oncologist could also alter the intensity of the beams to protect vital structures like the heart and large vessels.

Since nearly a decade, a team at MSKCC of radiation oncologists have utilized IMRT to treat mesothelioma. Their findings demonstrate that IMRT improves lung function, survival and reduces long-term side consequences such as radiation pneumonitis and radiation esophagitis. The mesothelioma patients studied had pleural mesothelioma confirmed by biopsy in the hemithorax and were not suitable for P/D or resection due to impaired pulmonary function. They were treated with an IMRT procedure to the hemithorax or without pleurectomy. In the group that received IMRT, overall survival was 71 percent at one year. It was 53 percent at two years.

Brachytherapy

The use of radiation therapy is to kill cancerous cells within mesothelioma which is a deadly cancer. It can also shrink tumors to make them easier to remove by surgery. It is a type of targeted treatment that uses narrow beams to prevent damaging healthy tissues around.

Radiation therapy can be utilized by itself or with other types of cancer treatments, such as chemotherapy. Many patients with mesothelioma also receive supplemental chemotherapy to lower the chance that cancer will return after surgery and make the treatment more effective.

Brachytherapy involves placing an radioactive source close to or within a mesothelioma tumor that allows doctors to deliver a larger dose of radiation to the tumor. The procedure requires hospitalization, and doctors may use a 137Caesium source or an Iridium source. The patient stays in a protected room with the source for 12-24 hours. A patient may experience some temporary side effects as a result of the procedure, such as a rash on the area of the implant and small amounts of bleeding from the area at which the applicator was put.

Another alternative is High-dose (HDR) Brachytherapy which involves placing a variety of radioactive sources around the tumor and delivering higher doses radiation over a longer amount of time. This treatment usually takes between three and five days, and involves an overnight stay in a hospital. Mesothelioma patients who undergo this kind of brachytherapy may also experience some short-term side effects, like discomfort at the site of insertion as well as a small amount of bleeding from the sites where the applicators were placed.

Because mesothelioma typically develops as multi-layered masses and is difficult to target with radiation. However, advances in technology have enabled radiation specialists to focus a beam at mesothelioma and away from surrounding tissues.

In some cases, mesothelioma patients may be given brachytherapy as part of an operative procedure known as Neoadjuvant Therapy or as a post-surgical adjuvant treatment to kill any lingering mesothelioma cells that the surgeon was not able to completely eliminate. In addition, some mesothelioma patients are treated with brachytherapy alongside pleurectomy/decortication and conventional radiation therapy as a palliative treatment for their symptoms.

Proton beam radiation

Radiation oncologists treat mesothelioma tumors in specific areas of the body. radiation treatment in mesothelioma of treatment allows for an improved method of treatment and reduces the chance of exposing healthy tissue to radiation at high levels. Patients with mesothelioma should discuss proton radiation therapy with their physician to determine if this is the best treatment for them.

The process of proton beam radiation begins with the radiation oncologist creating plans to treat the cancerous tissue. Dosimetrists utilize computers to calculate the exact amount of radiation required for the region. Doctors also decide on the amount of radiation to give and the location where it should be delivered. Dosimetrists pass the information to a physicist. The physicist uses a machine known as synchrotron to accelerate protons into the energy required to treat.

The protons are directed to the tumor through a mechanism similar to the CT scanner after they enter the treatment room. The patient will lie on a table that shifts into position to match the shape of the tumor. The physicist will then use a system that rotates beam's nozzle around the patient to ensure the radiation reaches all the areas of the tumor at the most optimal angles.

A gantry is a device that is used to direct and shape the proton beam. The gantry is surrounded by an immobilization frame that keeps the patient still while being treated. A computer regulates the gantry. It is monitored from an adjacent room by a team radiation technicians. The radiation oncologist can alter the treatment plan on each week's appointments if required.

In contrast to traditional photon radiation proton beam radiation does not penetrate the tissues of the lungs as deeply. This means that there is a lower risk of developing radiation-related complications including toxicity and the development of mesothelioma tumors that are resistant to treatment.

The proton beam is used to treat mesothelioma tumors in the pleural linings of lungs and the abdomen. It is essential to consult mesothelioma specialists who have prior experience working with proton radiation.
