The effectiveness of radiation therapy for prostate cancer
- mechanism of action
- Species radiotherapy
- Side effects
Radiation therapy for prostate cancer in our time is the leading method in the fight against cancer process.It is used to treat both limited and common forms of the disease.
Previously, prostate cancer can be the only way to get rid of - a radical removal of the prostate (prostatectomy), but now radiation for prostate cancer has a leading position.
Survival of patients (ten-year) after radiotherapy ranges from 75-85%.According to the degree of risk of complications radical prostatectomy gives way to radiotherapy.These statistics indicate the effectiveness and safety of irradiation.
mechanism of action
Special device emits radio waves of different lengths and frequency.The resulting beam targets the pathological focus.The body must necessarily be maintained in a certain position for accurate hit rays in the tumor and not
Sometimes, instead of X-rays used protons, which have a high destructive effect on cancer cells.There is also a method of introducing a radioactive implant directly into the prostate gland in the form of grains.
radiotherapy Radiation therapy for prostate cancer should be as efficient as possible.Therefore developed several types of radiation:
- Brachytherapy: the temporary and permanent;
Remote exposure is the most common method of treatment of cancer.Previously using a computer or nuclear magnetic tomography determined the localization of cancer.After research conducted irradiation of the tumor, being careful not to affect neighboring tissue.Duration of therapy is seven to eight weeks.Calibration is done on an outpatient basis, which also represents a certain advantage for patients.
prostate Radiation therapy, in which the tumor is installed directly in the radioactive component is under the control of ultrasound, called brachytherapy.This type of exposure helps to minimize the radiation dose and reduce the undesirable effects on healthy tissue.
for treatment in oncology using several options brachytherapy :
Unlike remote radiation, brachytherapy has a low degree of probability of complications and side effects.The postoperative period passed without consequence and well tolerated even in old age.
Contact therapy presently used less often.The method is based on the irradiation of the tumor during surgery.
This combined method of treatment of cancer certain stage and severity.
prostate irradiation, unfortunately, can not go unnoticed.After proydёnnogo treatment may appear dizuricheskie disorder (micturition disorders), which are held for a certain time.Sometimes there bleeding from the rectum, perianal area.In 25-30% of patients develop weak potency, until the development of impotence.
Radiation therapy for prostate cancer requires a long period of time to complete suppression of cancer cells, respectively, after treatment, patients proydёnnogo depleted and weakened.For a speedy recovery, you need to comply with certain conditions:
- exclude heavy physical exertion;
- control urination and defecation;
- limit the use of alcohol, narcotic and hallucinogenic substances;
- diet (eliminate greasy, spicy, acidic foods);
- periodically visit consultation oncologists.
If prostate cancer was detected in its early stages, treatment with radiation therapy will not only eliminate the disease but also preserve the integrity of the gland, and the patient returnsnormal physical and social activity.
