Louisville CyberKnife has treated over 100 patients in its first year through a partnership with the James Graham Brown Cancer Center, allowing doctors to collaborate across specialties. The center's medical director notes this collaboration gives patients access to multiple specialists. Additionally, the American Society of Radiation Oncology recently endorsed stereotactic body radiation therapy (SBRT) as a first-line treatment for prostate cancer. A five-year study showed SBRT successfully treated prostate cancer in 97% of low-risk patients and 90.7% of intermediate-risk patients, preserving sexual function in 75% of patients. The center hopes increased research will raise awareness of SBRT as a treatment option for other cancers.
