目的 :探讨中晚期前列腺癌的放射治疗的疗效。方法:1983～ 1999年共收治中晚期前列腺癌 17例 ,其中 B期 4例 ,C期 6例 ,D期 7例。均给予放射治疗 ,局部肿瘤量达 4 0～ 70 Gy,2 0～ 35次 ,4～ 7周。 结果:本组病例 5、10年生存率 5 7.14 % (8/14 )、30 % (3/10 )。所有病例放疗后排尿困难或骨转移疼痛改善 ,肉眼血尿消失。放疗后 6个月复查肿瘤明显缩小或消失者 85 .7% (12 /14 )。结论:中晚期前列腺癌的放射治疗可以缓解症状 。

Objective: To study the efficacy of the external irradiation treatment of advanced prostate cancer. Methods: Total seventeen cases of advanced prostate cancer patients were treated from 1983 to 1999 Four cases were in stage B. Six cases were in stage C and the other seven cases were in stage D.External irradiation treatment was performed on all patients. Local tumor doses were up to 40～70 Gy. Results: The actual survivals at 5 and 10 years were 57.14% and 30%, respectively. After radiotherapy, all cases were improved as to dysuria and bone metastatic pain and their haemuresis disappeared. Six months later, check of all the cases were done and found that local tumor disappeared or became markedly smaller in 12 of 14 cases (85.7%). Conclusion: External irradiation treatment of advanced prostate cancer can alleviate symptoms and increase survival rate.
