Cancer specialists can tailor proton beams to precisely match the shape and depth of a tumor, sparing critical organs and tissues and helping patients live longer with minimal side effects.
Traditional X-ray radiation involves both an entrance dose and exit dose that can damage healthy tissue before and after reaching its intended tumor site, but conformal protons and IMPT increase precision while decreasing side effects.
What is Proton Therapy Energy?
Proton therapy is an innovative type of radiation treatment that utilizes an intense beam of protons to target tumors with pinpoint accuracy while sparing healthy tissues and vital organs. With such pinpoint precision comes higher radiation dosages resulting in more positive patient outcomes with reduced side effects compared to traditional X-ray radiation therapies.
Each proton starts its journey at the injector, where hydrogen atoms are broken apart into negatively charged electrons and positively charged protons. Next, these protons pass through a vacuum tube in a pre-accelerator where they gain energy before passing through a ring of magnets that boosts it to between 70 million and 250 million electron volts – enough for any depth within human bodies.
As protons travel through a patient’s tissue, they interact with it and release energy that fights cancer cells without damaging healthy tissue. Physicians then choose an area for maximum proton release in order to target cancerous cells while protecting healthy tissues from damage.
Proton beams offer precision that makes them an excellent way to treat lymph nodes. Conformal proton beams can be used to target primary tumors while simultaneously irradiating any micro nests of cancer that might exist within surrounding lymph nodes – this combination with X-ray therapy is known as conformal proton plus irradiation therapy (CP+IRT).
How Does Proton Therapy Energy Work?
Proton therapy delivers cancer-killing radiation with pinpoint precision, sparing healthy tissue and organs nearby while reaching deeper into tumors where it is most needed while simultaneously lowering potential long-term side effects.
As part of the treatment process, a proton beam is guided towards the patient using magnets. Beginning at an injector, hydrogen atoms are separated into negatively charged electrons and positively charged protons that then travel through an accelerator tube into a vacuum tube where their energy can be increased to two million electron volts to penetrate even deep tissue layers in the body.
As the proton beam progresses through its journey, it travels around a synchrotron ring 10 million times each second and, during that time, a radiofrequency cavity within it delivers extra energy to boost their total power to between 70 million and 250 million electron volts – enough for targeting cancer cells at any depth within the body without harming healthy tissue.
Once a proton beam leaves a synchrotron, it travels via a beam transport system to one of four radiation treatment rooms at Loma Linda University Medical Center’s Proton Therapy Institute. Here, radiation oncologists use complex treatment planning systems and an intricate collection of magnets to shape, focus, and deliver proton radiation therapy directly onto patient bodies.
Radiation oncologists can customize proton beams to conform specifically to the unique shape of each patient’s tumor, thus minimizing exposure to healthy surrounding tissue. They may also combine conformal proton beams with X-ray radiation therapy in order to treat not only primary tumor but any involved lymph nodes as well – helping prevent the spread of cancer to other parts of the body while potentially uncovering hidden nests of tumors which would go undetected by standard X-rays alone.
Protons then travel to their target area of the body, where they damage cancerous cells by damaging their DNA and killing them off. Due to proton beam’s pinpoint accuracy when compared with other forms of radiation therapy such as IMRT, physicians can offer patients an even higher quality of life after treatment has concluded.
How Can Proton Therapy Energy Help You?
Selecting an effective cancer treatment can be daunting, which is why it’s vital to communicate openly and honestly with your cancer team about all available therapies, such as proton therapy. Proton therapy specializes in precision radiation that directly targets tumors while sparing surrounding healthy tissue while minimizing side effects – it is an ideal treatment option for complex tumors or those located near critical organs where conventional radiation cannot penetrate.
Proton beam therapy involves using a device known as a cyclotron to send positively charged protons into your body and shape and direct them towards the site of your tumor. Once inside, these positively charged protons will release their cancer-fighting energies directly onto the tumor itself, damaging or even destroying its cells and helping fight back against cancer.
Proton therapy offers more precise radiation, but may not always be medically necessary for all patients. Your cancer team will carefully consider each case to decide whether proton therapy offers more advantages over alternative treatments.
Your doctor will evaluate whether proton therapy is right for you based on factors including cancer type and stage, overall health status and treatment goals. If proton therapy is recommended to you, our team of specialists will create a personalized treatment plan, drawing from radiation oncologists and medical physicists as needed.
Once your treatment plan has been determined, we’ll help arrange visits to UF Health Proton Therapy Institute. While receiving cancer therapy sessions lasting 15-45 minutes each, daily noninvasive sessions will take place throughout your treatment program.
Your cancer team will use the treatment machine to target your tumor site once positioned. A mask will also help keep breathing easy during this process.
A cyclotron then emits a proton beam into your body with exquisite accuracy, targeting precisely where your tumor exists. This allows for higher doses of radiation to reach its center where they’ll have maximum impact in killing cancerous cells while simultaneously protecting nearby healthy tissue and organs from radiation that might cause long-term side effects.
How Can Proton Therapy Energy Help Your Patients?
Proton therapy energy allows radiation oncologists to target tumors more precisely than with traditional X-ray radiation therapy, sparing healthy tissues around cancerous cells and minimizing side effects and damage to nearby structures such as nerves, arteries and organs. Proton beam therapy may also be appropriate in cases when traditional X-ray radiation would be unsafe – such as with cancers located at the base of skull or chordomas that occur near sensitive brain and ear structures.
Radiation oncologists utilize a computer-based program known as a treatment plan to precisely direct proton beam therapy toward the exact site of tumor. A cone-beam CT scan then provides a three-dimensional view of both tumor and surrounding anatomy for maximum precision of proton beam delivery.
Proton therapy energy is tailored to target tumor sites while sparing healthy tissues before and after. This ensures a significantly lower risk of side effects than photon (traditional) therapy; indeed, one study found that patients who received proton beam therapy experienced twice as many days without severe side effects when compared to those receiving photon radiation therapy.
Proton beam therapy may be used alone or combined with surgery and chemotherapy as a cancer treatment option. It’s especially useful in cases when the tumor is near vital or delicate areas, such as the skull base or spine, such as when treating children who require feeding tubes due to malnutrition issues.
Proton therapy has been proven to increase overall survival and decrease high-grade complications among head and neck cancers caused by human papillomavirus (HPV). HPV-related head and neck cancers typically affect young adults and are treated through radiation, chemotherapy and surgery; with proton beam therapy’s precise delivery system it may limit damage to organs and structures while decreasing subsequent treatment costs for complications like skin issues, voice changes or hearing loss.
