Proton Therapy for Gastrointestinal Cancers

Proton Therapy for Gastrointestinal and Colorectal Cancers

Scripps Proton Therapy Center provides advanced radiation treatments for gastrointestinal and colorectal cancers.

Protons deposit their maximum therapeutic dose directly in the tumor. As a result, patients being treated for gastrointestinal or colorectal cancers receive smaller radiation doses to healthy structures adjacent to tumors, such as small intestine, lung, esophagus, heart, kidney and spinal cord. With the accuracy of proton therapy, patients may experience a reduced chance of side effects and secondary cancers.

About Proton Therapy


Proton Radiation Treatment for Gastrointestinal (GI) and Colorectal Cancers

Patients with gastrointestinal or colorectal cancers often undergo aggressive treatments to cure their disease, including combinations of surgery, chemotherapy and radiation. Because these cancer treatments can generate side effects, it’s important to make radiation therapy as gentle as possible.

Protons deposit their maximum energy in the targeted tissue, bringing less radiation to nearby organs and other critical structures. These benefits are especially pronounced for patients with advanced GI cancers of the pancreas, liver, esophagus and rectum. In these cases, protons can reduce unnecessary radiation to the bowel, heart, kidneys, spinal cord and bone.

This accuracy is even further enhanced by Scripps’ advanced imaging and pencil beam scanning technology, which focuses a narrow proton beam — smaller than the width of a pencil — to precisely target tumors.

What to expect

Each patient’s therapy is precisely tailored to their needs. Patients and clinicians collaborate closely to create a personalized treatment plan. The number and length of treatments will vary, based on the cancer. How patients respond depends on many factors, including the types of treatments they are receiving. Many people tolerate proton therapy well and continue to perform normal activities. However individual responses vary.

Proton therapy is a highly precise form of external radiation therapy that can be used for tumor control in select patients. All cancer treatments have advantages and disadvantages. Be sure to discuss these, as well as treatment options, with your cancer specialist.
