Accuray Incorporated announced positive data for CyberKnife stereotactic body radiation therapy (SBRT) for the treatment of cancer confined to the prostate.

Treatment with SBRT was effective with far fewer treatment sessions than are often required with traditional radiotherapy.

A recent study evaluated the use of sildenafil (Viagra) for preventing sexual side effects when taken after radiation therapy for prostate cancer. Participants were treated with sildenafil for 6 months and evaluated for 2 years. Erectile function questionnaire scores were significantly higher in the group who received sildenafil, suggesting an overall improvement in sexual satisfaction in these individuals.
