Proton Therapy Treatment FAQ’s

Proton therapy is a more refined form of radiation therapy that uses protons from hydrogen atoms rather than X-ray radiation or photons.

The practical difference between the two therapies is the distribution and absorption of the radiation. Conventional radiation passes entirely through the patient’s body, starting off strong and getting weaker and weaker as it passes through. Consequently, the radiation from conventional therapy is absorbed by the surrounding organs in the process, which causes varying side effects dependent on the area of the body where the tumor lies.

In contrast, proton therapy stops at the site of the tumor, so it terminates cancerous cells but spares the normal, healthy surrounding tissue. Due to the accuracy of the proton beam, side effects are may be lower, providing a higher quality of life for a patient throughout their treatment and limiting long-term side effects in the future.

As proton therapy is another form of radiation, all cancers responsive to conventional radiation will be able to be treated. This includes cancers and tumors in the breasts, brain, prostate, lungs, head and neck, base of the skull, spine, gastrointestinal, gynecologic malignancies and others.

Proton therapy is the ideal treatment for pediatric patients, since the targeted dosage of radiation avoids much of the nearby surrounding tissue. This limits the risk of future health conditions that can arise as a result of young patients being treated with photon radiation, which impacts more of the surrounding areas.

Not all cancers or clinical conditions require proton therapy. Our experts have experience in all radiation therapy modalities such as photon (x-ray) therapy, electrons and brachytherapy and will recommend the type of radiation or combination of radiation that is best for you.
Yes, all patients will be treated by the same physician for the full duration of their treatment.
If you need other therapies or services during your radiation therapy such as chemotherapy, blood work or imaging your physician team at MPTC can work with your oncologist or connect you with our experts at the University of Maryland Medical Center.
At MPTC we are happy to continue to work with your other doctors for combined care. Our physicians, nurses and nurse practitioners are experienced in working with physicians both in and out of state. If however you need a referral to another type of specialist we are also happy to connect patients to our experts at the University of Maryland Medical Center.
No, proton therapy is not experimental. Proton therapy treatment began in the mid-1950’s and was approved by the U.S. Food and Drug Administration in 1988. To date, over 100,000 people have received proton therapy as part of their cancer treatment in centers all over the United States and the world. Some types of cancers show improved results with proton therapy while others show similar results.

Physicians from the Maryland Proton Treatment Center have participated in many research studies demonstrating the efficacy of proton therapy. View of list of them here.

Proton therapy only causes hair loss if the treatment area bears hair. Unlike chemotherapy, which is a systemic treatment, forms of radiation like proton therapy only affect the specific area of the body being treated.
MPTC uses the Varian ProBeam® Proton Therapy System, which is one of the most advanced systems in the world. The specific form of radiation is called “pencil-beam scanning” or “intensity modulated proton therapy” (IMPT).

It uses a 90-ton cyclotron to accelerate protons to two thirds the speed of light, sending them down a beamline the length of football field and into one of five treatment rooms.

Four of five of our treatment rooms feature a rotational gantry. This hidden 3-story tall machine helps move the treatment nozzle up to 360 degrees into the precise position to deliver your treatment.

The beam is delivered without sound or pain in a matter of minutes with millimeter precision.

On any typical day, you may spend anywhere from an hour to an hour and a half with us while undergoing proton therapy. This entails getting checked in, changed, being called back to the treatment room, getting set up on a table, imaged and treated.
If you have received radiation to treat a past cancer, you may still be a candidate for proton therapy.

Because proton therapy offers precise tumor targeting, physicians can limit the amount of radiation that healthy tissues near the tumor receive. This means that physicians can treat tumors more aggressively, with higher doses of radiation, without higher risk.

If your tumor has grown back (recurrence), aggressive treatment is often the best course of action. Proton therapy puts radiation back on the table as a treatment option for recurrent tumors.

One of the primary indications for proton beam therapy is in patients who have had previous radiation therapy.

The idea that proton beams could play a role in treating cancer was proposed in 1946 by Dr. Robert Wilson, who is considered to be the “father of proton therapy”.

From the mid 1950’s on, proton treatment began for a limited number of cancers, with computing and treatment delivery technology advancing rapidly over the next 30 years.

By the 1980’s, these advancements made proton therapy a viable option for treating localized solid tumors in many areas of the body and proton treatment facilities began to open. Up until the last ~10 years however, proton therapy remained a scarce resource in our country with only certain types of tumors being treated. Over the last 10 years, more centers have opened and as a result a wider variety of cancers are now treated.

In 2016, the Maryland Proton Treatment Center opened as the first center in the region to offer proton therapy with the most advanced form of proton therapy in the world, called pencil beam scanning. We have treated over 2000 patients and counting with the most experienced team in the region.

Proton Therapy Cost FAQ’s

In our experience, around 85% of patients are approved for coverage by their insurance provider. Some private insurance companies cover proton therapy for specific disease sites (cancer types) or on a case-by-case basis. We will work on your behalf to obtain coverage including communicating the facts and clinical recommendation for proton therapy, providing comparative treatment plans and setting up physician-to-physician consultations between our team and your insurance provider when necessary.
Proton therapy is generally covered by Medicare (non-HMO). In many cases, patients covered by Medicare supplemental insurance often incur few net-out-of-pocket expenses for treatment after deductibles, copays/coinsurance, and annual maximum payments are met.

We also work with insurance providers from around the country.
