Prostate Cancer

Proton Therapy for Prostate Cancer

Proton therapy (or proton beam therapy) is one of the most advanced forms of radiation therapy in the world, making it an ideal prostate cancer treatment.

With protons, a high dose of radiation can be delivered directly to the tumor, while avoiding unnecessary radiation to nearby healthy tissue and vital organs. This decreases the risk of damage to the rectum and bladder.

Studies have shown that using proton therapy for prostate cancer results in excellent rates of cancer control and very low rates of serious complications in the bowel or bladder, as compared with other forms of treatment.7

Ideal treatment option for prostate cancer

Avoid unnecessary radiation to nearby organs

Decrease risk of long-term side effects

Increase overall survival rate1

About Prostate Cancer

Prostate cancer is the second most common type of cancer among men and represents about 10% of all new cancer cases in the United States. Based on data from the National Cancer Institute, approximately one out of every nine men will develop prostate cancer during their lifetime. As of 2017, more than 3 million men in the U.S. were living with prostate cancer.8

The Benefits of Proton Therapy

Research continues to demonstrate that proton therapy can lead to better outcomes for many prostate cancer patients. For instance, data released at the 2017 PTCOG national conference revealed:

Decreased Side Effects

Increased Survival Rate

Significantly fewer patients treated with proton therapy reported gastrointestinal, genitourinary, endocrine or “other” complications compared with intensity-modulated radiation therapy (IMRT). In addition, the proton beam therapy group’s 5-year overall survival rate was 93.25%, compared to 88.43% for IMRT. Patients who received proton therapy report highest quality of life compared to surgery, x-ray, or brachytherapy patients.2

Proton Therapy By The Numbers

5% increase in Overall Survival Rate for intermediate risk prostate cancer1

21% decrease in risk of urinary toxicity5

25% decrease in risk of erectile dysfunction6

35% decrease in radiation to the bladder3

42% decrease in relative risk of developing a secondary malignancy1

50% decrease in treatment-related bowel frequency and urgency5

59% decrease in radiation to the rectum3

Comparing Proton Therapy to other treatment options

When considering your treatment options for prostate cancer, it’s important to compare the impact each of them could have on your quality of life. Some treatments result in a higher risk of side effects. Some of those side effects are short-term, while others are long-term. We are strong advocates for each patient finding the prostate cancer treatment plan that is best for him.

The interactive illustration below compares proton therapy to traditional radiation (x-ray/IMRT) when treating prostate cancer. Proton therapy reduces the risk of side effects by delivering significantly less radiation to surrounding organs like the rectum and bladder. Slide the arrow to see the difference in radiation exposure to healthy tissue and vital organs surrounding the cancerous tumor. The colored areas are exposed to radiation, while the gray/white areas are not.

Proton Therapy Improves Quality of Life During & After Treatment

Men treated for prostate cancer using proton therapy reported significantly better quality of life than other therapy options. A national survey profiled 755 men, ages 50-75, at least 12 months after prostate cancer treatment. Patients who received proton therapy reported the best outcomes for overall quality of life, urinary function, sexual function, ability to remain active during treatment, and living life the way they wanted to after treatment.

Notably, the chart below shows more than 70% of proton therapy patients reported that treatment did not interfere at all with their overall quality of life.

Patient Stories

When someone is diagnosed with cancer, life’s focus turns to cancer treatment, quality of life, care, and cure. During this journey, there are a myriad of emotions, and there is no greater comfort than connecting with someone who has been down this path before.
