How Radiation Treatment In Mesothelioma Has Changed My Life The Better
Radiation Treatment in Mesothelioma

Mesothelioma patients could undergo radiation therapy as part of their pleural mesothelioma treatment plan. It can help reduce the likelihood that cancer will recur following surgery.

Radiation therapy is a form of radiation that damages DNA in cells and kills them. It can be given before or after surgery.

Doctors often combine it chemotherapy to improve the results of surgery. It can also help alleviate symptoms by shrinking tumors that cause discomfort such as breathlessness.

External beam radiation therapy (EBRT)

This treatment uses x rays or particles that come from an outside machine to destroy cancerous cells. It can be administered prior to or after surgery and chemotherapy to eliminate cancerous cells in the area and also as a palliative treatment to alleviate symptoms like shortness of breath. Mesotheliomas do not grow as a single distinct tumors, and therefore it's difficult to target radiation towards them while protecting healthy tissue. Newer techniques are helping overcome this issue.


Experts in radiation use computers to create detailed images of the tumor and adjacent healthy tissues. These images help them decide the amount of radiation to use and where it should be directed. This information is used by a huge machine to place the radiation beam over the tumor in a precise manner. The majority of EBRT procedures require treatment five days a week for a period of weeks, but certain patients require less treatments. Each session lasts between 15 and 30 minutes, although most of the time is spent getting the patient in the correct position for the treatment.

The kind of EBRT that is used to treat mesothelioma will rely on the location of the tumors and the health of the patient. It could be a standard version of EBRT, referred to as three-dimensional conformal radiation therapy (3D-CRT) or a more sophisticated technique such as intensity-modulated radiation therapy (IMRT). In some instances, it may be combined with a specific method, such as stereotactic body radiation therapy to treat larger tumors, or with other treatment options like intraoperative radiation therapy to treat smaller tumors that cannot be surgically removed.

Another option for treatment is proton beam radiation therapy, which involves aiming particle beams (like protons or helium particles) at a tumour from various angles. This allows for more precise targeting of the site of cancer and minimizes damage to healthy tissues and organs in the vicinity. However proton beam radiation therapy isn't widely employed in Australia for mesothelioma.

A different kind of radiation, intraoperative radiation therapy (IORT) is utilized in conjunction with surgery to try and remove any mesothelioma that can not be surgically removed. This is a quick procedure that takes only few minutes to complete.

Intensity-modulated radiation therapy (IMRT)

IMRT is a treatment that allows doctors to treat tumors without causing harm to healthy tissue. It is a treatment that makes use of a medical linear accelerator (LINAC) machine that creates photons, or X-rays, to focus on the tumor and the surrounding tissue. The machine is able to rotate around the patient permitting the beam to be directed on several different angles to ensure that each area is being treated. This lets the doctor administer more doses to the tumor, while also protecting the healthy tissues surrounding it from damage.

IMRT is used in conjunction with Image-Guided Radiation Therapy (IGRT) which aids the physician to target the exact area of cancer. IGRT uses computerized imaging, like CT scans or X-rays along with MRI scans if they are available to aid the radiation oncologist to locate the mesothelioma and surrounding areas with precision. Once the area of interest is located, IMRT can be used to design an treatment plan that targets the mesothelioma in a precise manner.

The IMRT system also allows the doctor to tailor the treatment according to the individual anatomy of each patient and reduce the risk of adverse negative effects. Radiation oncologists typically provide patients with five daily IMRT treatments per week, lasting between five and eight consecutive weeks. Each session is between 15 and 30 minutes. The daily dose of radiation helps protect the body's normal tissues. It is also important to note that a weekend break is usually required so that the body's healthy tissues can recover.

The IMRT technique has produced positive results in patients suffering from mesothelioma of the neck and head. It is particularly beneficial when tumors are located close to radiosensitive structures, like the parotids. A recent study found that IMRT could deliver a large dose of radiation to the cancer without damaging the adjacent parotid. The parotid glands that were spared recovered to 63 percent of their pre-treatment levels in comparison to just 3 percent in patients who received conventional radiation. This is a highly promising outcome, but more research needs to be conducted. To confirm these preliminary findings large-scale IMRT trials will be required.

Brachytherapy

If doctors aren't able to eliminate mesothelioma in its entirety, radiation can help shrink the tumor and lessen symptoms. Palliative care is what this is called. Doctors combine it with other treatments such as chemotherapy and neoadjuvant therapies to extend the lifespan of patients.

Radiation therapy involves the use of x-rays to kill cancerous cells from an outside machine. New techniques, like IMRT, allow doctors to better target the area around the tumor, and limit radiation damage.

Certain types of radiation may also be used inside the body to kill cancerous cells. In brachytherapy, doctors place a radioactive source that is sealed in or near the mesothelioma. This can be done with a catheter or an applicator. Doctors can then deliver doses of radiation from a device outside the body to target the source. This is known as external radiation therapy (EBRT).

Doctors can use either high-dose or pulsed-dose radiation in brachytherapy. With the former patients, they stay in the hospital and receive 10 minutes of sessions each day for a period of 2 weeks. High-dose brachytherapy isn't as popular due to the need for a larger machine and longer exposure times.

Another form of brachytherapy employs protons instead of x-rays. Because they are physical particles, protons don't absorb into tissues as easily and can cause less damage to the surrounding areas. However, this kind of radiation is more expensive and is not as widely available as xrays.

Mesothelioma patients may need to undergo radiation therapy for several weeks or more. This may be difficult to tolerate. Patients should consult with their physicians about any adverse effects they could encounter during treatment. Patients should also ask their doctors for advice on how to minimize adverse effects.

As part of a multimodal plan for treatment mesothelioma patients can also benefit from immunotherapy and genetic therapy. Immunotherapy boosts the immune system, and mesothelioma patients who have had chemotherapy can benefit from immunotherapies to boost their chemotherapy regimen.

Researchers are also looking at ways to improve the results of radiation therapy for mesothelioma. One way is to combine brachytherapy and immunotherapy, which involves injecting cells that are infused with the drug Yervoy into the chest cavity. mesothelioma treatments have shown that this treatment works. Gene therapy is a different approach that involves replacing mesothelioma tumor cells with genes or repairing them in order to limit their growth and make them more prone to chemotherapy.

Radiation therapy after surgery

The treatment of radiation therapy is not a cure for mesothelioma however it can improve the chances of survival for the patient. When utilized in conjunction with other treatment methods can shrink mesothelioma-related tumors and ease the discomfort and pain that cancer causes. It can also lessen the risk of mesothelioma cancer cells spreading after surgery or following the removal of the lung tumor (known as seeding).

Each session lasts around 30 minutes. The procedure can be uncomfortable because the radiation oncologist needs to place and hold the patient in a certain position.

Before the session begins patients should dress in a comfortable way. Avoid wearing anything that is made of metal since it can interfere with the precision and accuracy of the equipment. Patients should also eat six small meals frequently to avoid nausea.

Depending on the patient's condition, they may be offered a standard or brachytherapy version of radiation. In conventional treatment, doctors use a machine called a linear accelerator deliver the radiation. This is the most commonly used mesothelioma treatment. It is usually used to treat mesothelioma that is a cancer that develops in the lining of the lungs.

Brachytherapy is a sophisticated treatment that utilizes a source of radiation placed within the body. The implant can be inserted temporarily or permanently. When inserting the implant, the surgeon must ensure that only cancerous tissue is targeted, and not the surrounding organs.

In some mesothelioma clinical trials researchers are looking at the possibility of combining radiation therapy and surgical procedures for patients with resectable pleural mesothelioma. One example is the SMART trial. This experimental treatment plan involves providing patients with extrapleural pneumonectomy prior to radiotherapy hemithoracic. This combination of treatments allows doctors to give patients greater doses of radiation and reduce the risk of mesothelioma post-surgery seeding.

A mesothelioma patient can undergo a partial or complete remission. This means that the tumor size has decreased or even disappeared completely. Some patients have experienced remission for a long time, and have lived past their initial prognosis.
