Salvage cryosurgery of the prostate after radiation failure

Radiation therapy is one option for patients with localized prostate cancer. Despite advances in delivering radiation to the prostate gland with therapies such as brachytherapy and/or external beam radiation therapy, urologists will be faced with managing patients with rising prostate-specific antigen values and with positive biopsy results secondary to radiation-recurrent prostate cancer. If the cancer is detected early, salvage therapy can be initiated. Since salvage prostatectomy is associated with significant morbidity, patients are often left with the option of either watchful waiting or temporary palliation with hormone deprivation therapy, with its attendant toxicity. The introduction of third-generation cryotechnology using 17-gauge CryoNeedlestrade mark (Oncura, Inc., Plymouth Meeting, PA) and the recent modifications in the technique of salvage cryosurgery have enabled cryosurgeons to eradicate these tumors safely and with significantly decreased morbidity. Selection and management of patients, as well as the contemporary results of salvage cryosurgery, are discussed in this article.
