CHICAGO--(BUSINESS WIRE)--For men undergoing proton therapy for prostate cancer, fewer treatments with higher doses appear to be well tolerated, according to early clinical trial results. The trial, which continues to enroll patients, is evaluating using only 5 proton treatments given over 2 weeks for patients with low risk prostate cancer, a fraction of the 44 treatments typical in an 8-week standard course of therapy.
“There is evidence that proton therapy results in fewer side effects compared to standard X-ray radiation therapy. With more research into shorter courses of treatment, we will continue to see the cost of the treatment come down while still maintaining the same quality of life patients have come to expect.”
Patients who underwent the short-course of treatment reported no change in pre-treatment gastrointestinal, genitourinary or sexual function 6 months after completing therapy; no change in hormonal status was noted. The study reported on the outcomes of the first 22 who have completed treatment; more than 45 patients have now been enrolled on the protocol.
“This early analysis shows that short-course treatment is well tolerated, a result we continue to see in additional patients who we have enrolled in the trial and who have completed their therapy,” said Dr. William Hartsell, medical director of the CDH Proton Center, A ProCure Center, in Warrenville, Ill. “Being able to successfully treat patients in just a fraction of the time is not only convenient for patients, it also translates into substantial cost reductions.”
The study, which is led by Dr. Hartsell, is being conducted in the suburban Chicago center as well as the ProCure Proton Therapy Center in Oklahoma City. Ten patients were treated over 1 to 2 weeks at a higher dose for 5 treatments; another 12 patients were treated over 8 to 9 weeks with a standard proton dose and 44-day course of treatment. Prior to undergoing treatment and every 3 months following, side effects were monitored using industry-standard, patient-reported outcome measurements.
Data on the trial were presented at the Radiological Society of North America (RSNA) 98th Scientific Assembly and Annual Meeting.
Proton therapy for prostate cancer is clinically proven to be beneficial. Earlier this year, four studies, including one from ProCure, presented at the American Society for Radiation Oncology (ASTRO) annual meeting showed that proton therapy successfully reduces treatment related side effects and helps maintain a high quality of life for men with prostate cancer. The studies found little to no decline in genitourinary and gastrointestinal function for men treated with proton therapy and a faster return to pre-treatment function compared to standard X-ray radiation therapy.
“The body of research showing the benefits of proton therapy for prostate cancer is growing,” Hartsell said. “There is evidence that proton therapy results in fewer side effects compared to standard X-ray radiation therapy. With more research into shorter courses of treatment, we will continue to see the cost of the treatment come down while still maintaining the same quality of life patients have come to expect.”

AT A GLANCE
- Early results show short-course proton therapy treatment is well tolerated in the treatment of low risk prostate cancer.
- Patients receiving 5 proton therapy treatments with higher doses reported similar quality of life scores to those treated in standard 44 treatments.
- Reducing the number of sessions cuts treatment period to 1 to 2 weeks from 8.
About CDH Proton Center, A ProCure Center:
CDH Proton Center, A ProCure Center, Warrenville, Ill., is one of a handful of facilities in the country that offer proton therapy, an advanced form of radiation to treat cancer. The four-room, 60,000 sq. ft. Center, opened Oct. 19, 2010, is the first for Illinois and has the capacity to treat up to 1,500 patients a year. The precision of proton therapy spares healthy tissue and results in fewer short- and long-term side effects than treatment with standard X-ray radiation therapy. Proton therapy has been shown to be beneficial in the treatment of a broad range of tumor types including head and neck, brain, central nervous system, prostate, lung, sarcomas, gastrointestinal and many pediatric cancers. It is especially effective for treating children and adults with anatomically complex tumors such as at the base of the skull and tumors along the spinal cord. The CDH Proton Center, A ProCure Center, is a collaboration between Central DuPage Hospital (CDH), Radiation Oncology Consultants (ROC) and ProCure Treatment Centers, Inc. ProCure was founded in 2005 in Bloomington, Ind., and is developing a network of proton therapy centers in cities across the United States. For more information, visit www.procure.com/il.
