Mesothelioma Radiation Treatment
Mesothelioma radiation therapy uses X-rays and other energy beams to shrink tumors and keep their growth or spreading. It can be given at any stage of mesothelioma as an option to treat the disease and prolong its the life of the patient or as an alternative treatment to ease symptoms.
Radiation is also used by doctors before surgery to shrink the tumor, which makes it easier for surgeons. They can also make use of it to kill any cancer cells that remain after surgery and to stop a recurrence.
External beam radiation therapy
Radiation therapy uses high-energy beams of X-rays or particles that eliminate cancerous cells. Mesothelioma tumors usually grow as multiple, small regions of tissue, making it hard to aim radiation at the tumor, and spare nearby healthy tissues. new mesothelioma treatment options techniques allow doctors to pinpoint the tumor, and limit the damage to other parts of the body. Radiation therapy can be used to destroy cancer cells that remain after surgery or chemotherapy. It can be used by itself or in conjunction with palliative therapies to reduce symptoms of mesothelioma, like pain and difficulty breathing.
For external beam radiation therapy, doctors employ a device to direct radiation towards the mesothelioma cancer from outside the body of the patient. The doctors utilize a CT, MRI, or PET scan to determine the exact location of mesothelioma. They then design a plan to deliver radiation to the affected area while limiting damage surrounding tissue. Radiation oncologists may mark your skin in freckle-sized dots so they can locate the affected area. They also mark the treatment area, which is the area that requires treatment.
You'll be lying on a bed for treatment and an instrument will be positioned on the area of your body with mesothelioma. You might be asked to change positions several times during your experimental treatment for mesothelioma however, you won't feel or see the machine moving around your. During the procedure, you might hear whirring or clicking sounds from the machine. The radiation doctor will monitor you from an observation room.
EBRT is usually done 5 days a week at least once per day for 2-8 weeks. Based on the type of radiation and the purpose of treatment, you will receive different treatments. Certain kinds of EBRT like intensity-modulated radiotherapy or IMRT makes use of computers to more accurately target the tumor and reduce radiation exposure to surrounding tissues.
Other forms of radiation, such as proton-beam radiation or SBRT make use of particles instead of X radiation. Proton beam radiation damages DNA in 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 aligns the radiation beams to the 3-dimensional shape and size of the tumor using 3-D computed-tomography (CT). This allows for higher doses of radiation to be delivered to the tumor while minimizing exposure to organs and tissues surrounding it. In addition to pleural mesothelioma treatment, IMRT can be used to treat lung cancer, prostate cancer, sarcomas, head and neck tumors.
In studies of patients with complex tumours, IMRT produced superior dose distributions and less toxicity when compared with conventional radiation techniques. Radiation oncologists employ IMRT to plan the course of treatment for their patients with mesothelioma and make sure that the radiation is aimed at the correct part of the body. The radiation oncologist talks to the patient and seeks informed consent before deciding if IMRT is appropriate for mesothelioma treatment.
Together, the radiation oncologist and medical physicist create an individualized IMRT treatment plan for mesothelioma. Radiation therapists perform the actual IMRT treatment. During the sessions the patient lies down on a table. The patient may hear noises or smell odors emanating from the equipment, however they shouldn't feel discomfort. The medical physicist and radiation oncologist remain outside of the room to observe from a secure distance.
During the IMRT session the radiation oncologist will alter the intensity of radiation as needed to better target the cancer. The radiation oncologist may also alter the intensity of each beam, which can help safeguard vital structures like the heart and large blood vessels.
At MSKCC, a team of radiation oncologists has utilized IMRT to treat mesothelioma over the past decade. Their results indicate that IMRT improves lung function, longevity and reduces long-term side effects like radiation esophagitis and radiation pneumonitis. The mesothelioma patients examined had pleural mesothelioma treatment mesothelioma survivor confirmed by biopsy in the hemithorax. They were not candidates for P/D or resection because of impaired pulmonary function. They were treated with IMRT to the hemithorax, with 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
Mesothelioma can be a deadly cancer, radiation therapy eliminates cancerous cells. It can also shrink tumors, making them easier to remove via surgery. It is a targeted treatment that uses narrow beams to protect healthy tissue in the vicinity.
Radiation therapy is utilized either on its own or in combination with other treatments for cancer like chemotherapy. Many patients with mesothelioma also receive supplemental chemotherapy to decrease the chance that cancer will recur after surgery and make their treatment more efficient.
Brachytherapy is the process of placing the radioactive source near or inside a mesothelioma tumour, which allows doctors to deliver a larger dose of radiation to the tumor. Doctors may utilize a 137Caesium or Iridium source for this treatment and requires hospitalization. The patient is placed in a shielded area with the source for a duration of 12-24 hours. This procedure can cause minor side effects, Pleural Mesothelioma Treatment such as soreness around the site of the implant and a small amount of bleeding around the area where the applicator is positioned.
Another alternative is high-dose (HDR) brachytherapy which involves placing multiple radioactive sources around the tumor and giving a higher dose of radiation over longer periods of time. This treatment is typically performed over a period of 3 to 5 days and requires a hospital stay. Mesothelioma patients who undergo this type of brachytherapy might also experience certain short-term side effects, including soreness around the area of insertion as well as a small amount of bleeding at the site where the applicators were placed.
It is often difficult to pinpoint radiation since mesothelioma is usually a multi-layered tumor. However, newer technology has allowed radiation doctors to precisely target an arc of radiation at the mesothelioma tumor, and stay clear of surrounding tissues.
In certain cases mesothelioma treatments patients are given brachytherapy as part of the preoperative treatment known as neoadjuvant therapy or as an adjuvant post-surgical treatment to kill any lingering mesothelioma tumors that the surgeon was unable to completely remove. 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 use proton beam radiation to target specific parts of a patient's body where mesothelioma tumors can be found. This kind of treatment is more precise and reduces the chance that healthy tissues will be exposed to high levels radiation. Patients with mesothelioma must discuss proton radiation therapy with their physician to determine if it is the best option for them.
Radiation oncologists develop a plan to treat cancerous tissue prior to beginning the proton beam treatment. Dosimetrists make use of computers to calculate the exact dose of radiation needed for the specific area. The doctors also determine which part of the body to place radiation, and how far into the body it should travel. Dosimetrists pass the information to a physicist, who makes use of a device called a synchrotron to accelerate protons into the energy needed to treat.
The protons are directed to the tumor by a system similar to a CT scanner after they enter the treatment room. The patient will lie on a table which moves to a position that matches the shape of the tumor. The physicist employs a system to rotate the proton beam's nozzle around he patient in order to ensure that radiation reaches the tumor at the highest angle that is possible.
A device called a gantry is used to direct and shape the proton beam. The gantry is surrounded by an immobilization frame which keeps the patient in a seated position while they are being treated. A computer controls the gantry. It is monitored from a nearby room by a team of radiation technicians. The radiation oncologist may change the treatment plan on each week's appointments if required.
In contrast to traditional photon radiation proton beam radiation doesn't penetrate the lung tissues as deep. This means that there is less chance of radiation-related complications like toxicity and growth of mesothelioma cancer cells which are resistant.
The proton beam can be used to target mesothelioma cancers in the lung's pleural lining and abdomen. It is essential to consult mesothelioma experts who have prior experience working with proton radiation.
