Benefits of Proton Therapy

General

Proton therapy patients experienced a two-thirds reduction in the relative risk of severe side effects within 90 days of treatment (when compared to x-ray radiation therapy)1

11.5% or 45 of 391 patients receiving proton therapy experienced a severe side effect in the 90-day time frame compared to 27.6% or 301 of 1,092 for the X-ray radiation therapy group’s severe side effects.1

Brain Cancer

31% increase in disease control for aggressive tumors at base of skull (chordomas) at 5 years.2

50% less likely to have secondary brain tumor from treatment.3

55% reduction in average dose to the hippocampi (memory function) in treatment of meningioma.4

Prostate Cancer

5% higher 5-year overall survival in intermediate risk.5

Patients who received proton therapy report highest quality of life compared to surgery, x-ray, or brachytherapy patients.6

35% less radiation to the bladder and 59% less radiation to the rectum.7

42% reduction in relative risk of developing a secondary malignancy.8

50% reduction in treatment related bowel frequency and urgency at 2 years.9

21% lower risk of urinary toxicity at 2 years.9

25% lower risk of erectile dysfunction at 2 years.10

Breast Cancer

88% less radiation dose to the heart for left sided breast cancer.11,12

44% reduction in clinically significant radiation doses to the lung.12

90% of partial breast irradiation cases result in good to excellent cosmetic outcomes at 5 years.13

Well tolerated – Less than 4% serious side effects (grade 3) in locally advanced breast cancer.12

10% increase in local cancer control at 5 years in stage II-III.22

15% decrease in distant metastasis at 5 years in stage II-III.22

26% reduction in pulmonary toxicity compared with X-ray therapy (IMRT).23

21% reduction in the risk of severe, treatment related lymphopenia, particularly in lower esophagus.24

3-4-day reduction in average hospital stay after surgery.25
