Radiation Failure on Treating Prostate Cancer

HIFU (high intensity focused ultrasound) uses high-energy sound waves to destroy prostate cancer cells, without radiation. Intersect precisely focused ultrasound waves raise the temperature within the targeted cancerous tissue greater than 80-90 degrees Celsius per second, effectively destroying the tissue.

Unlike radiation therapy, ultrasound energy is non-ionizing "clean energy", which does not damage the tissue around the target zone.Cilj zone is about 1 / 8 inch in diameter, which allows greater precision of radiation therapy. Unlike radiation, HIFU treatment can even be repeated in the case of the disease recurring at a local level. HIFU May also be used as salvage therapy following failed radiation.

HIFU procedure is performed on an outpatient basis, which means a stay in hospital is often not potrebno.Postupak be performed under spinal or general anesthesia and usually takes about 2-3 hours. During the procedure, a tiny probe is inserted into the rectum, which generates and transmits ultrasonic energy to precisely aims prostate. Your doctor will monitor the prostate all the way through the process with real-time ultrasound images in order to maximize destruction of prostate cancer and reduce injury to other vital tissues.

HIFU treatment for prostate cancer has not yet been approved by the U.S. Food and Drug Administration. However, until now, more than 6,000 people have been subjected to HIFU to more than 100 international HIFU centers worldwide. Each year, more than 40,000 men with prostate cancer who were treated with radiation have cancer vratiti.Većina will decide on hormonal therapy in an attempt to control their cancer. Hormone therapy prohibits the production of testosterone to slow the growth of cancer. However, the decrease in testosterone can cause side effects such as osteoporosis, increased risk of heart attack, stroke, loss of libido, depression, loss of mental acuity, and impotence. HIFU is radiation free and destroy the remaining cancer within the prostate using ultrasound to clean energy. In a small safety trial of the United States, 91% of respondents have a negative biopsy 6 months after HIFU treatment.

a typical short-term adverse effects associated with radiation include fatigue, urinary and rectal symptoms. Urinary symptoms may include frequency, urgency, urge incontinence, nocturia and decreased urinary stream. May Rectal symptoms include diarrhea, fecal incontinence, rectal bleeding and rectal urgency. Generally, urinary and rectal symptoms are transient. In addition, erectile dysfunction often develops months or years after radiation therapy. Long-term complications are rare and include rectal or urinary fistula, urinary stricture, hemorrhagic cystitis and proctitis (chronic bleeding from the rectum and bladder) and the dysfunctional bladder or rectum as a result of scarring. There is growing evidence that people undergoing pelvic radiation significantly higher risk of developing cancer of the colon and urinary bladder.

Salvage radical prostatectomy is also technically challenging procedure because of the prostate is embedded in the fibrous scar produces radiation. So, minimally invasive ablative therapies receive increasing acceptance for treatment of recurrent prostate cancer after failed radiation, which is really HIFU. Many patients who have had radiation, brachytherapy or external beam radiation experience an increase in PSA have discovered that the cancer had returned. These patients may be candidates for HIFU also, so long as the cancer has not spread to bones or other organs. In addition, patients who have local return after receiving intensive prostatectomy may qualify for HIFU.
