Interventional radiology treatments for recurrent prostate cancer
April 12th, 2010 Posted in radiation therapyA new study at Mayo Clinic in Rochester, Minn. suggests that 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.
According to the study leader, the men underwent salvage therapy treated with either MR-guided laser interstitial thermal therapy, which uses high temperatures generated by local absorption if laser energy, or cryoablation, generating freezing with extremely cold gas destroying cancerous tissue. By using MR imaging with temperature mapping and/or ice ball growth monitoring, clinicians tailored treatments to lesion size and location.
Immediately after treatment, Mayo researchers found no definite residual tumor. The treatment preserved the patients’ baseline sexual and urinary function and had no major complications.
