NJA中华男科学杂志National Journal of Andrology Zhonghua Nan Ke Xue Za Zhi2013,19(9):815-819http ://www.androl.cn·论著·Clinical Research(临床研究)前列腺癌内分泌治疗方法研究及预后分析黄宝星,宿恒川,曹万里,孙福康(上海交通大学医学院附属瑞金医院泌尿外科,上海200025)【摘要】目的:探究延长前列腺癌患者进展为激素非依赖性前列腺癌(AIPC )时间的内分泌治疗方法。

方法:经直肠活检穿刺证实前列腺癌患者93例,分为3组:22例患者接受双侧睾丸切除加比卡鲁胺联合治疗,行持续性全雄激素阻断(CAD );71例患者行间歇性内分泌治疗方法,其中29例患者行标准间歇性内分泌治疗(IAD ),42例患者行改良型间歇性内分泌治疗;两组治疗期用戈舍瑞林或亮丙瑞林联合比卡鲁胺的用药方案,行雄激素最大阻断(MAB ),当患者血清PSA 下降至<0.2μg /L ,维持用药3个月。

进入间歇期,IAD 组停药,改良型IAD 组停用促黄体生成激素释放激素类似物(LHRH-a ),但维持使用比卡鲁胺,两组在间歇期内出现PSA 持续升高,且大于4μg /L 时,则再次启用MAB ,直至患者进展为AIPC 。

比较CAD 、IAD 及改良型IAD 3组患者疾病随访时间、疾病进展时间及治疗周期。

结果:3组患者人口学特征、基线资料及随访时间相似,中位进展时间分别为(26.50ʃ4.15)月、(30.00ʃ7.83)月和(34.93ʃ5.08)月,CAD 与标准IAD 组比较差异无统计学意义(P =0.143),改良型IAD 组与CAD 及IAD 组比较差异有统计学意义(P =0.001,0.032)。

Kaplan-Meier 生存分析显示,改良组中位进展时间明显长于标准IAD 治疗组(P =0.01)。

标准IAD 与改良型IAD 组平均治疗周期分别为(16.13ʃ3.33)月和(19.58ʃ4.30)月,两组第1治疗周期间歇期分别为(9.6ʃ3.2)月和(14.2ʃ3.7)月,组间比较差异显著(P =0.001)。

结论:与CAD 和标准IAD 比较,改良型IAD 可显著延长前列腺癌患者进展为AIPC 的时间。

然而,随着治疗时间的延长,几乎所有的前列腺癌均会进展为激素非依赖性前列腺癌(androgen-independent prostate cancer,AIPC),一旦发展为AIPC,患者的预后往往很差。

如何延长行内分泌治疗的前列腺癌患者发展为AIPC的时间,是晚期前列腺癌治疗需面对的难题[1]。

标准间歇性雄激素阻断(intermittent androgen deprivation,IAD)可提高患者生活质量,减轻经济压力[2],但研究表明其延长肿瘤进展作用与持续性雄激素阻断(continuous androgen deprivation,CAD)相似,与传统内分泌治疗相比可能并无生存优势[3]。

为探究延长患者进展为AIPC时间的方案,我们分别采用不同的治疗策略,针对患者进展为AIPC时间的影响因素进行了回顾性分析,现报告如下。
