伽玛刀治疗前列腺癌前后PSA水平改变对预后的评估
Chinese Medical Equipment Journal(2008)
Abstract
目的:观察伽玛刀治疗前列腺癌对PSA水平的影响及PSA水平的变化对疾病预后的评估。方法:伽玛刀治疗38例患有前列腺癌的患者,治疗前测每位患者血清PSA值,治疗后3个月检测血清PSA值进行比较,同时了解患者的生存状况,计算3 a生存率。结果:随访3个月后,有34例PSA值恢复正常,症状缓解率100%,患者的生存质量得到不同程度改善。治疗前PSA水平≤20 ng/ml的3 a生存率较PSA水平>20 ng/ml高,总的3 a生存率87%(33/35)。结论:通过检测治疗前后PSA值,可以评估伽玛刀治疗前列腺癌的疗效及预后。
