Sexual function does not continuously decline after radiation therapy treatments for prostate cancer

Sexual function in prostate cancer patients receiving external beam radiation therapy (EBRT) decreases within the first two years after treatment but then stabilizes and does not continuously decline as was previously thought, according to a study in the January 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

Prostate cancer is the most common male cancer other than skin cancer. It can be effectively treated using multiple methods, including prostatectomy, brachytherapy and EBRT, so the long-term side effects are often used by patients and doctors as deciding factors when choosing a treatment.

Changes in sexual function are some of the more common side effects from prostate cancer treatments, but the degree to which EBRT affects function varies widely, depending on the study.

In a first of its kind study, researchers at the Jefferson Medical College of Thomas Jefferson University in Philadelphia, the Thomas Jefferson University Hospital Department of Radiation Oncology in Philadelphia and the University of California, Davis, School of Medicine Department of Radiation Oncology in Sacramento, Calif., evaluated 143 prostate cancer patients receiving EBRT who completed baseline data on sexual function before treatment and at follow-up visits.

Radiation Therapy Oncology Group and US Oncology Enter Collaboration to Increase Patient Access to National Clinical Trials

HOUSTON, October 16, 2008—The Radiation Therapy Oncology Group (RTOG) and US Oncology, Inc. today announced they have entered into a collaboration to increase patient access to national cancer clinical trials with a radiation focus in the community setting.

The collaboration means patients receiving cancer care at practices affiliated with US Oncology have access to RTOG trials for disease sites including brain, head & neck, lung, gastrointestinal, genitourinary, cervix, and breast cancers. RTOG trials focus on testing the integration of radiation therapy with new systemic therapies and surgery.

The collaboration also marks the first time US Oncology, as a network of member practices, has participated in cooperative group trials in radiation oncology. In addition, US Oncology is the first multi-state, national organization to become an affiliate member of RTOG. Current members include large regional practices and academic practices with several facilities in metropolitan areas.
