Mesothelioma treatments are performed in various means, including radiation. Radiation treatment is often performed using a linear accelerator (LINAC) machine, commonly used for external beam therapy. This therapy aims highly focused beams of radiation at the edges of the site where cancer is found, destroying any abnormal cells and preventing growth or regrowth of the tumor while sparing the normal tissue. LINAC can also be used in sterotactic radio surgery similar to using a gamma knife on the targets within the brain.
The LINAC uses a microwave technology, similar to that used for radar, to accelerate electrons and then allowing the electrons to collide with a heavy metal target. High energy x-rays are scattered from the target, a portion of which is collected and shaped to form a beam that matches the patient’s tumor. The patient lies on a moveable treatment couch and lasers are used to ensure the patient is in the proper position. Radiation can be delivered to the tumor from any angle by rotating the device and the treatment couch.
A trained radiation oncologist will prescribe the treatment, while a radiation physicist and dosimetrist determine the best way to deliver the dosage and calculate the time required to deliver the dose. A radiation therapist will operate the LINAC.
LINAC is used in a large percentage of radiation therapy in the United States, as well as various treatment centers in Canada, New Zealand, and Great Britain. Using LINAC allows treatment facilities to deliver more treatment to a greater number of patients, thereby reducing wait times for radiation patients.
