HIFU, or Intense Focused Ultrasound, is a non-surgical strategy for treatments for localized cancer of the prostate. HIFU focuses ultrasound energy and sound waves to a targeted area in the prostate producing rapid temperature increases and focal ablation of the treatment zone with great accuracy. In most cases, HIFU is completed with an outpatient basis a single to four hours depending on the sized the prostate. The largest benefit from HIFU is an extremely low incontinence rate of below 2% as well as a post-treatment erection dysfunction rate of 20 to 30%. The true secret to success with HIFU, however, is proper patient selection. Candidates include men with low- to intermediate-risk localized cancer of the prostate (i.e., no spread of cancer outside of the prostate). These men would've clinical stage T1 or T2b disease (i.e., no palpable nodule or nodule confined one lobe with the prostate), Gleason score of seven or less (preferably not higher than Gleason Score 3+4=7), PSA amount of less than 20, along with a prostate volume of 40 grams or fewer. Initial data for treatment of appropriately selected men with HIFU has demonstrated results comparable to other modalities regarding localized cancer control, biochemical recurrence, and disease-free survival. Additionally, reported incontinence and male impotence rates after HIFU are quite low at less that 2% and 20 to 30%, respectively.
Benefits of HIFU as a way of treating select men with cancer of the prostate incorporate a non-surgical, non-invasive technique requiring no hospital stay. Additionally, the prostate type of cancer tissue is destroyed without the radiation exposure. HIFU is repeatable should re-treatment become necessary in the future. Additionally, HIFU enable you to treat recurrent prostate cancer that's initially treated by other means, for example radiation or proton therapy. Another impressive putting on HIFU to treat localized prostate cancer is based on emerging successes with focal therapy of prostate kind of cancer. During these select cases, studies would be performed to ensure a low-volume of prostate kind of cancer limited by one lobe or even a specific focal site inside prostate. The involved lobe or even the specific site in the patient's prostate type of cancer would then be focally treated. Candidates for focal HIFU include men with low-volume (below or equal to 3 cores positive for cancer, not one core with more than 50% positive), Gleason Score of 6 or fewer, and a PSA of less than 10. These men would undergo "template" or "saturation" biopsies with greater to 24 cores evaluated. Recent surveys taking a look at focal therapy of prostate type of cancer in very select men with low-volume disease are emerging and early results look promising although no lasting data is yet available. Early results in some studies show as much as 90% recurrence free survival following focal therapy in observed at close range men. Incontinence rates following focal HIFU were 0 to 1% and erectile dysfunction rates under 5% a single study investigating results at three and 6 months following treatment.
HIFU is really a minimally invasive treatment option for men with low- to intermediate-risk prostate type of cancer. The key for the success like all options for treatment lies in appropriate candidate selection. HIFU is conducted internationally which is currently undergoing clinical trials for FDA approval in america. American urologists are been trained in performing HIFU and work with American teams internationally as a way to offer this treatment to appropriately selected patients interested in HIFU as a technique of treating their cancer of the prostate. Keep in mind, make sure to discuss all options using your urologist including the risks, benefits and choices to each prior to the best decision regarding treating your cancer of the prostate. Maintain open and honest discussions together with your doctor when contemplating these options as the answer to business energy is finding the treatment that best suits you plus your particular cancer the very best.
