PROSTATE CANCER

Prostate cancer is common urological cancer, early often asymptomatic, most of the patients when treatment is already advanced. Some patients because of distant metastases, traced search for the source of prostate cancer at diagnosis. The treatment of prostate cancer is still a radical resection of the prostate, endocrine therapy and radiotherapy. For the treatment of advanced prostate cancer, hormonal therapy and that radiation therapy is the most effective means. Common methods for testicular castration operation, anti - androgen drugs such as flutamide, a KANG Shi.

Endocrine therapy for the treatment of early prostate cancer satisfied with the results, but with the passage of time, transformed into a prostate cancer - androgen-independent cells, a PSA rise, affecting endocrine therapy. Radiation therapy is the treatment of advanced prostate cancer effective method, interference radiation on DNA synthesis, can effectively kill tumor cells, reduce infiltration around the tumor and lower. Apart from the radiation therapy, radiation particles implant brachytherapy, in recent years the rapid development of new technologies, the effect of high-low complication of normal tissues to radiation damage to the minimum extent. Particulate radiation brachytherapy implant can be used in early and advanced prostate cancer.

Prostate cancer brachytherapy method is the basic specifications of a certain number of sources directly inserted into the prostate, prostate cancer cells to high doses. In order to be satisfied with the treatment site dose, must formulate specific preoperative treatment planning system, according to sources around the dose distribution of the rules with a certain amount of these radioactive sources. Prostate cancer radiation therapy using CT, MRI and other imaging computer 3D reconstruction of the pool cloth reasonable and reliable. Through tablets tablets source of activity and spacing adjustment to the target dose uniformity, the target dose of a sudden drop, which will help protect normal tissue. Using the short half-life of radioactive nuclides, to kill or inhibit the proliferation of fast tumor cells more favorable. Treatment is simple, injury, protective security, and other benefits. Current prostate brachytherapy treatment of multiple choice I Pa 103 or 125.

Two Zhejiang Medical Center urology in the province in the first brachytherapy treatment of prostate cancer, nearly five years for a total of 100 cases of prostate cancer, including many other cases of failure, through our years of observation, patients with most cases PSA values decreased significantly, and prostate cancer mass was soft, small change, no serious complications in patients with prolonged survival time and improve the quality of life. Through clinical analysis, we believe that brachytherapy treatment of brachytherapy treatment of prostate cancer is an effective alternative method.
