Methods: From 1983 to 1999, 17 cases of advanced prostate cancer were treated, including 4 cases in stage B, 6 cases in stage C and 7 cases in stage D. All were given radiotherapy, local tumor volume of 40 ~ 70 Gy, 20 ~ 35 times, 4 ~ 7 weeks. Results: The 5-year and 10-year survival rates were 5 7.14% (8/14) and 30% (3/10) in this group of patients. All cases of dysuria after radiotherapy or bone metastases to improve the pain, gross hematuria disappeared.
