At the MD Anderson Proton Therapy Center, we partner with referring physicians to provide the best possible care for their patients. We work closely with referring physicians to answer questions and help streamline referrals. Once treatment is complete, we are happy to coordinate and follow up with patients in conjunction with their referring physicians.
About Proton Therapy Treatment
Proton therapy is a type of particle therapy which uses a beam of positively charged protons to irradiate cancerous tumors. Because of the protons unique ability to distribute the radiation dose more directly to the tumor, it minimizes the damage to nearby healthy tissues.
Though many tout proton therapy as “new,” it has actually been used to treat patients for more than 20 years. In the 1950s, proton therapy was first used in a lab setting; in 1964 Harvard cyclotron was used in clinically; and in 1990 it began being used in a hospital setting to treat patients with cancer and other diseases.
Intensity Modulated Proton Therapy (IMPT)
IMPT is best used to deliver a potent and precise dose of protons to the most complicated tumors, ones that largely reside embedded in the nooks and crannies of the head and neck or skull base. Learn more about this new evolution of cancer treatment.
Clinical Indications & Benefits of Proton Therapy
Proton therapy can be very beneficial to tumor sites requiring a higher degree of dose conformality when the tumor is contiguous to clinical structures such as the heart, lungs and esophagus. Pediatric tumors, thoracic tumors, lymphoma, and tumors of the brain, head and neck, prostate and liver are just a few of the tumors that respond well to proton beam radiation treatment.
Patients who receive proton therapy treatment often have improved tumor control, reduced side effects and potentially lower incidence of secondary malignancies. Because of the ability to precisely target and irradiate tumors while sparing critical and sensitive structures nearby, we are able to increase the radiation dose. This is especially beneficial to patients who are undergoing combined treatments of chemotherapy and radiation; pediatric patients whose bodies are still growing and developing; those with tumors that have become resistant to chemotherapy and require a high dosage of radiation for tumor control; and those with tumors that are near healthy tissues and critical structures.
