TUESDAY, March 16 (HealthDay News) -- In patients with locally recurrent prostate cancer following radical prostatectomy, magnetic resonance-guided ablation using laser interstitial thermal therapy or cryoablation may be a feasible treatment, according to research presented at the Annual Scientific Meeting of the Society of Interventional Radiology, held from March 13 to 18 in Tampa, Fla. In addition, cryoablation may be a feasible treatment for breast cancer patients who refuse surgery, according to other research presented at the conference.

In one study, David A. Woodrum, M.D., of the Mayo Clinic in Rochester, Minn., and colleagues conducted a retrospective review of four men with post-surgical recurrent prostate cancer, including two treated with magnetic resonance-guided laser interstitial thermal therapy and two treated with cryoablation. After treatment, the researchers found no definite residual tumor. They also found that treatment preserved the patients' baseline sexual and urinary function and resulted in no major complications.

In a second study, Peter J. Littrup, M.D., of the Barbara Ann Karmanos Cancer Institute in Detroit, and colleagues studied 13 patients with 25 breast cancer foci, which were treated in 13 cryotherapy sessions. After an average follow-up of 18 months, they observed no local recurrences.

"Magnetic resonance-guided ablation may prove to be a promising new treatment for prostate cancer recurrences; it tailors treatment modality (imaging) and duration to lesion size and location and provides a less invasive and minimally traumatic alternative for men," Woodrum said in a statement.
