Prostate cancer cryotherapy for prostate cancer
Cryotherapy is a very new treatment for prostate cancer. Also cryosurgery and cryoablation, cryotherapy of the prostate known, is a minimally invasive and able to use the controlled freezing and thawing to destroy the disease.
Cryotherapy role in the treatment of prostate Cancer, Because cryotherapy is relatively new, the absence of many studies on the rate of long-term survival, cryotherapy is not as common as radiation therapy for primary treatment used. Cryotherapy, is effective in the treatment of prostate cancer that are resistant to radiation and shall be repeated. Some doctors think that the use of gel instead of higher doses of radiation therapy is more effective for radiation resistant prostate cancer.
Prostate cancer Cryotherapy works because the freezing of ice crystals form around cells within and around them. Freezing and thawing of the cells through a process of dehydration, dramatic changes in pH values destroyed, or prevented the movement of red blood cells. Send to freeze the prostate, particularly negative 40 degrees Celsius, also activates an anti-tumor response in the body. An anti-tumor response begins with the production of antibodies that work to remove the prosttae cancer tumor.
History Cryotherapy,Cryoablation Translated tissue destruction by freezing. The idea with temperatures below zero in the treatment of prostate cancer, especially in the prostate tissue radiation resistant, the 19th since the Century, used as mixtures of ice and salt in the breast or has been given for the treatment of cervical cancer. Modern cryotherapy began in 1966 with the use of liquid nitrogen. If cryotherapy was used for the first time, was fully invasive surgery. The first form of cryotherapy causes a perineal incision through the instrument was brought called a cryoprobe. Liquid nitrogen is circulated through the probe to freeze the gland. In 1974, doctors began transperineal with a minimally invasive.
Today the third generation cryotherapy needles used more efficiently by managing transrectal ultrasound. Only recently has the technology available, the surgeon can carefully place and forms an ice ball, which will destroy the prostate tissue. Technological advances are changing cryoneedles cryoprobe using transrectal ultrasound guidance, change in liquid nitrogen, argon and helium, and use a warming catheter.
Advantages and disadvantages of primary Cryotherapy, Cryotherapy is an effective treatment for people in the early stages of prostate cancer at low risk of metastasis. This can also be an excellent alternative for those who are not good candidates for radical prostatectomy. Cryotherapy can be used without external beam radiation and prostate cancer cells, which are radiation resistant. Some of the benefits, including the day of hospitalization, although some patients stay overnight, depending on your health.
Cryotherapy can be repeated to remove if not, be the cancer tissue in the first phase of treatment. Patients who can not seek alternative treatments such as radiotherapy or radical prostatectomy. Because cryotherapy is minimally invasive, patients experience a slight, if any, loss of blood. A disadvantage is that long-time data on cryotherapy for its novelty in the general treatment of prostate cancer is limited.
