HIFU, or Intense Focused Ultrasound, is a noninvasive strategy for management of localized prostate kind of cancer. HIFU focuses ultrasound energy and soundwaves to a targeted area in the prostate leading to rapid temperature increases and focal ablation with the treatment zone with great accuracy. In most cases, HIFU is conducted while on an outpatient basis a single to four hours depending on the size the prostate. The most important good thing about HIFU is a very low incontinence rate of under 2% along with a post-treatment male impotence rate of 20 to 30%. The key 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 not in the prostate). These men would have clinical stage T1 or T2b disease (i.e., no palpable nodule or nodule confined one lobe with the prostate), Gleason score of 7 or fewer (preferably not in excess of Gleason Score 3+4=7), PSA amount of lower than 20, as well as a prostate amount of 40 grams or less. Initial data for treatment of appropriately selected men with HIFU indicates results much like other modalities with regard to localized cancer control, biochemical recurrence, and disease-free survival. Additionally, reported incontinence and erectile dysfunction rates after HIFU may be low at less that 2% and 20 to 30%, respectively.
Benefits of HIFU as a means of treating select men with prostate kind of cancer add a non-surgical, non-invasive technique requiring no stay in hospital. Additionally, the prostate type of cancer tissue is destroyed with no radiation exposure. HIFU is repeatable should re-treatment become necessary in the foreseeable future. Additionally, HIFU may be used to treat recurrent cancer of the prostate that has been initially treated by other means, including radiation or proton therapy. Another impressive putting on HIFU to treat localized prostate type of cancer is in emerging successes with focal therapy of cancer of the prostate. During these select cases, studies would be performed to be sure a low-volume of cancer of the prostate limited by one lobe or possibly a specific focal site inside prostate. The involved lobe or perhaps the specific site of the patient’s prostate cancer would then be focally treated. Candidates for focal HIFU include men with low-volume (less than or corresponding to 3 cores positive for cancer, no one core with in excess of 50% positive), Gleason Score of 6 or fewer, along with a PSA of under 10. These men would undergo "template" or "saturation" biopsies with greater to 24 cores evaluated. Recent reports looking at focal therapy of prostate cancer in very select men with low-volume disease are emerging and early results look promising although no long lasting details are yet available. Early brings about some research has revealed around 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% in a study looking at results at three and six months following treatment.
HIFU is really a non-invasive treatment selection for men with low- to intermediate-risk prostate cancer. The important thing to the success as with most selections for treatment is in appropriate candidate selection. HIFU is carried out internationally and it is currently undergoing numerous studies for FDA approval in the usa. American urologists are trained in performing HIFU and help American teams internationally in order to offer laser hair removal to appropriately selected patients considering HIFU as a means of treating their cancer of the prostate. Of course, be sure to discuss all options together with your urologist like the risks, benefits and alternatives to each prior to an educated decision regarding treatments for your prostate kind of cancer. Maintain open and honest discussions along with your doctor when thinking about these options as the step to business energy is locating the treatment you want plus your particular cancer the very best.
