How effective is targeted cryotherapy in the treatment of prostate cancer?
In the August 2002 peer-reviewed supplement of the journal Urology results of a seven year study of 590 cryo patients found that 92% of low-risk cancer patients, 89% of moderate-risk patients, and 87% of high-risk patients were disease free. In another study presented at the 1998 World Endo-Urology Conference, 97% of patients treated with targeted cryosurgery showed no signs of cancer at one year. Five-year combined data for both traditional cryosurgery and targeted cryotherapy show that of 988 patients treated, 82% had negative biopsies. This data is especially significant for moderate-to-high risk tumors, which are less successfully treated with surgery and radiation.
