Promising results for 5-day stereotactic body radiation therapy in early stage prostate cancer

Preliminary results show that a shortened course of radiation therapy for prostate cancer called stereotactic body radiation therapy (SBRT) provides good PSA response for early-stage prostate cancer and has the same side effects as other treatments, according to a March 15 study in the International Journal of Radiation Oncology*Biology*Physics , the official journal of the American Society for Radiation Oncology (ASTRO).

First-degree family history of prostate cancer does not affect some treatment outcomes

In a first of its kind study, a first-degree family history of prostate cancer has no impact on the treatment outcomes of prostate cancer patients treated with brachytherapy (also called seed implants), and patients with this type of family history have clinical and pathologic characteristics similar to men with no family history at all, according to a January 1 study in the International Journal of Radiation Oncology*Biology*Physics , the official journal of the American Society for Radiation Oncology.
