Objective: To investigate the clinical effect of 125I radioactive seed implantation\nand the treatment of prostate cancer with radical resection of prostate\ncancer. Methods: Within the period of the second phase, 62 cases of prostate\ncancer patients, aged from 46 to 87 years old, average 69 years old. In the\ntreatment group, 30 cases were implanted with 125I radioactive particles via\nthe rectum with the guidance of the rectum. 32 cases in the control group\nunderwent radical prostatectomy. Results: All patients were operated successfully,\nthe patients were followed up for 12 to 36 months. In the treatment\ngroup, the average particle size was 38 + 15. No serious complications caused\nby rectal puncture. 2 patients occurred 6 months after PSA increased significantly,\nsystemic examination revealed bone metastases, and underwent endocrine\ntherapy. In the control group, there were 2 cases of patients with PSA\nsignificantly increased in 5 months after surgery, and the external irradiation\nplus endocrine therapy. During the observation period, the survival rate of\nthe patients who were implanted with 125I particles in the treatment group\nwithout progression was 93.3%. Control group, the cumulative PSA progression\nfree survival rate was 93.7%. Conclusion: Patients with prostate cancer\nduring the second phase, the clinical curative effect of the treatment of prostate\ncancer with the treatment of 125I of prostate cancer and the treatment of\nprostate cancer by using radical resection of prostate cancer are quite. This\ntechnology has the advantages of small trauma, quick recovery, low damage\nto normal tissue
