Proton Therapy Austin Texas
Proton therapy is an innovative form of radiation therapy that uses a proton beam to directly transmit radiation to the tumor, killing cancer cells while sparing healthy tissues. With a low radiation dose, protons enter the body, stop at the tumor, match its form and volume or depth, and deposit the bulk of their cancer-fighting energy right at the tumor.
Proton therapy directly applies high-energy proton beams to tumors, reducing damage to healthy tissue surrounding them and critical organs. Proton therapy is especially effective treating children and in cancers located close to critical organs and sensitive areas.
Physicist Robert R. Wilson, Ph.D. first proposed the concept of using protons in medical care in 1946. The first attempts to use proton radiation to treat patients started in nuclear physics testing laboratories in the 1950s but implementations were limited to a few areas of the body. As of July 2017, there are over 75 particle therapy facilities worldwide, with at least 41 others under construction. As of June 2018, 27 operational proton therapy centers are in the United States. As of the end of 2015 more than 154,203 patients had been treated worldwide.

Advantage of proton therapy: Targets tumors and cancer cells with precision and minimal exit dose. Reduces overall toxicity. Reduces the risk and/or incidence of side effects on healthy tissue. Proton therapy is most commonly used at MSK for treating head and neck cancer and pediatric cancers. We also are using it increasingly to treat spine tumors, breast cancer, sarcoma, brain tumors, and prostate cancer. A system called a cyclotron provides proton therapy, which sends a high-energy beam of protons through the skin into the tumor. At Memorial Sloan Kettering, a CT or MRI scan to map the tumor in three dimensions is the first step. In close collaboration with medical physicists, radiation oncologists then use computer programs to determine how to administer the treatment at the exact dose and venue.

Patient will receive proton therapy in a special treatment room, where the patient will be positioned on a treatment table. An immobilization device will make sure stay in the exact position on the table. Proton therapy treatments usually last about 30 minutes from the time the patient enter the treatment room to the time you leave. Although proton therapy destroys cancer cells by a similar mechanism to that used in traditional x-ray radiation — by destroying their DNA. Owing to the peculiar physical properties of protons, however, doctors may be able to administer radiation to a particular body depth. All energy has been released by proton therapy by the time it hits the tumor site, so there is no dose after that point. It can help to decrease side effects. Proton therapy usually requires the same number of procedures as traditional radiation therapy and the same session times.
The Texas Proton Therapy Center includes the latest generation of proton technologies and a patient-centered approach to treatment. All three treatment rooms have pencil-beam scanning of latest generation. Small proton beams, measuring only millimeters wide, are rapidly scanned across the tumor to precisely match the shape of the tumor. It enables therapy to adapt to diverse, formed or even moving tumors and decreases excess radiation to healthy tissues.
Physicians also use cone beam computed tomography (cone beam CT), which uses 3-D volumetric imaging (vs. 2-D X-ray images) to provide improved visualization, better patient positioning, and more precise treatment of cancerous tumors. As therapy decreases the size of the tumor, advanced diagnostic imaging, including PET / CT and a 3-Tesla MRI, is used to update the treatment plan.
Proton therapy:
- Is especially effective in treating cancers in sensitive areas and for children whose bodies are still growing.
- Uses high-energy, precisely targeted proton beams to destroy cancerous cells, leading to a lower recurrence rate for many patients.
- Decreases damage and harm to healthy tissue and essential organs surrounding it.
- It is non-invasive and can mitigate side effects.
- Often it improves the chemotherapy tolerance of patients.
- During and after surgery, patients can retain their current quality of life;Is sometimes effective in treating areas already treated with radiation.proton therapy Austin Texas
Latest Generation Technology
The 63,000-square-foot Irving-Las Colinas facility features an advanced fixed beam treatment room and two isocentric gallery treatment rooms; each gallery room has a 30-foot, 110-ton system that rotates 360 degrees to enable the most precise placement of proton beams on submillimeter-accurate patient tumours. A 220-ton cyclotron anchors the proton beam machinery, which can accelerate the protons to nearly the speed of light.All three treatment rooms feature pencil-beam scanning. Small proton beams, measuring only millimeters wide, are rapidly scanned across the cancer target to precisely match the shape of the tumor. It allows for adaption to complex shaped or even moving tumors, improves dose conformity, and reduces excess radiation to normal tissues.proton therapy Austin Texas
Patient-Centered Approach
The Texas Proton Therapy Center is committed to producing more cancer survivors and enhancing their quality of life as well. Our patient-centered approach to care is evident in the new center, which is designed to create a positive and supportive patient experience. The center offers a full range of patient support services, focused therapeutic activities for patients, families, and caregivers, and a children’s activities room. The patient support services also assist out-of-town patients.Proton Therapy | Texas Oncology
