Why St. Jude for radiation therapy?

We provide the highest quality of care for our patients who need radiation therapy:

  • St. Jude has one of the nation’s largest teams of radiation oncologists who care solely for children.
  • St. Jude is at the forefront of developing ways to reduce or eliminate side effects from radiation therapy.
  • St. Jude offers state-of-the-art facilities and equipment, including proton beam radiation therapy. Proton therapy kills cancer cells while sparing healthy cells, and may lessen the severity of side effects that affect brain function after treatment for some types of brain tumors. The St. Jude Proton Therapy Center is the first center in the world that treats only children with this therapy.
  • Our research studies have guided doctors around the world. These studies have resulted in less radiation given to children over the past 20 years. St. Jude research methods are the model for radiation therapy clinical trials across the U.S. and the world.
  • Our way of doing clinical trials helps guide other national brain tumor trials. We use 2 advanced radiation therapy treatments, known as intensity-modulated radiation therapy (IMRT) using photons (x-rays) or intensity-modulated proton therapy. These methods help doctors make a 3-D map of the tumor. This helps them aim the radiation directly at the tumor cells to kill them while sparing nearby healthy cells. This approach has helped increase the cure rates of some cancers and reduced side effects for children with some types of brain tumors. 

More reasons to choose St. Jude for care include:

  • We are consistently ranked among the best childhood cancer centers in the nation by US News & World Report.
  • At St. Jude, we have created an environment where children can be children and families can be together.
  • St. Jude patients and families never pay for services authorized by St. Jude.
  • We lead more clinical trials for childhood cancer than any other hospital in the U.S. 
  • St. Jude is the only National Cancer Institute–designated Comprehensive Cancer Center just for children. A Comprehensive Cancer Center meets rigorous standards for research that develops new and better approaches to prevent, diagnose, and treat cancer.
  • The nurse-to-patient ratio at St. Jude is about 1:3 in hematology and oncology and 1:1 in the Intensive Care Unit.
     

Radiation therapy team

The St. Jude radiation therapy team works closely with other specialists at St. Jude to make sure that your child is getting the best care possible for their needs.

Our team includes:

  • Pediatric radiation oncologists who treat cancers, sickle cell anemia, and aplastic anemia using radiation therapy 
  • Nurse practitioners or physician assistants who assist your oncologist with your child’s care
  • Physicists who understand and guide the use of radiation
  • Anesthesiologists who give special medicines to relieve pain during surgery or procedures
  • Nurses who give specialized care for your child’s disease 
  • Radiation therapists who provide treatment with radiation
  • Child life specialists who use play and relaxation to help your child cope with their treatment and hospital stay
  • Clinical research staff who help manage and perform clinical trials and collect information to learn more about disease treatment

Meet your radiation therapy team.
 

What to expect during your visit 

Radiation therapy uses high-energy radiation (electromagnetic waves) aimed at harmful cells to help control your child’s disease.

The radiation oncologist and other members of the care team will talk with you about the best type of therapy for your child and develop a treatment plan.

Depending on your child’s condition and eligibility, the care team may suggest that your child take part in a clinical trial. They will answer any questions you have about treatment and follow-up.

Consultation

During your consultation, you will meet with members of your care team. They will help answer your questions about treatment.

Your care team will talk to you about informed consent. This is a process in which you give permission before treatment can start. The team will explain the goal of radiation treatment and any radiation side effects your child may have. 

Simulation

During the simulation phase, the team plans your child’s treatment. If a tumor is found, your child may have a CT scan and MRI to help the team find the tumor’s exact location, size, and shape. The team uses this information to aim the radiation at the correct place to kill the cancer cells and reduce damage to nearby healthy cells. The steps of simulation are:

  • A radiation therapy team may put marks on your child’s skin with a permanent marker or paint pen so they can easily see where to aim the radiation each time. You may wash the area gently but do not scrub. Scrubbing can remove the marks and irritate your child’s skin.
  • Instead of the marker, the team may place very small tattoos (freckle size) on your child’s skin using a very small, sterilized needle.
  • The team may fit your child for a device, which helps keep your child in the same position during each treatment. The device could be a mask or body mold made for your child, which is marked to guide the radiation to the correct place on your child’s body.
  • It is important that your child’s body stays in the correct position during radiation treatment. This helps the radiation therapy kill more cancer cells and reduce the damage to normal cells.

A physicist and radiation oncologist will decide how much radiation to give and where the radiation should be targeted (known as mapping).

Treatment

The radiation oncologists will tell your child that it is important to be still during the treatment. An anesthesiologist or child life specialist may also help your child to stay comfortable and still during therapy.

Your child will get their radiation treatment as an outpatient, meaning they do not have to stay at the hospital. The care team will tell you how often they need to come, and how long they will need radiation. The therapy plan depends on the type of cancer or anemia your child has.

The radiation oncologist will explain:

  • How long each radiation treatment will take: It may take some time for your child to get into the right position, and this part may take longer than the actual treatment.
  • How long radiation treatment will last: Treatments will often be 4–5 days a week for several weeks, as small daily doses help to protect the skin.
  • How many “rest” days there will be in between treatments: Usually, your child will get rest time on the weekends, as time off helps healthy cells recover.

A scheduler from your child’s care team will help you make the radiation appointments.

Follow-up visits

After treatment, your child’s radiation oncologist will meet with you for follow-up visits. Your child may need more imaging tests, such as CT scans, ultrasounds, or x-rays, to see how well the treatment is working and if the cancer is spreading (known as monitoring). They will also note any side effects your child may have.
