Gamma knife radiosurgery for vestibular schwannomas: tumor control and functional preservation in 70 patients.
We present the previously unreported outcomes of 70 patients treated with Gamma knife radiosurgery for vestibular schwannoma (VS), including comprehensive analysis of clinical outcomes and the effects of lower marginal doses. ⋯ In the treatment of VS, contemporary radiosurgical techniques and the use of marginal doses below 13 Gy offer excellent tumor control, at high rates relative to surgical intervention. These findings are independent of marginal dose and tumor size. Patients should be informed about the benefits and risks of radiosurgery and microsurgery before choosing an intervention. Further analysis of post-treatment outcomes should be encouraged as follow-up times increase and the treatment protocols continue to evolve.

Formation of combined urology and radiation oncology practices: objective data from radiation oncologists for rationale.
We sought to determine motivating factors for radiation oncologists to form joint ventures with urologists to provide intensity modulated radiation treatment (IMRT) to prostate cancer patients that the urologists diagnose. ⋯ This data may indicate that radiation oncologists combine with urologists in a geographic area where the radiation oncologist has been economically displaced, has existing referral patterns, and continues to treat other patients with nonprostate malignancies.
